Rheumatoid arthritis is an inflammatory disease driven by TH1 CD4(+) cells. Interleukin-10 is present in higher concentrations in serum and synovial fluid from patients with rheumatoid arthritis and has a marked anti-inflammatory activity. Furthermore, it is capable of stimulating B cells and increasing autoantibody production. Interleukin-10 synthesis is under genetic control. Objective. Three polymorphisms of the promoter region were analyzed for interleukin-10 genes -1082, -819 and -592. Subjects were patients with rheumatoid arthritis compared with a control population for these genes. Material and methods. One hundred two patients with rheumatoid arthritis and 102 matched healthy controls were studied. The following data were taken from the rheumatoid arthritis patients: age of disease onset, presence and titers of rheumatoid factor, and history of replacement joint surgery. Genotypes were obtained by polymerase chain reaction and sequence-specific primer method. The three polymorphisms are in strong linkage-disequilibrium and form three haplotypes -1082A/-819C/-592C, -1082A/-819T/-592A y -1082G/-819C/-592C. Results. No association was detected between Interleukin-10 alleles, haplotypes/genotypes and rheumatoid arthritis. No significant differences occurred between interleukin-10 polymorphisms and age of disease onset, presence and titer of rheumatoid factor and history of major joint replacement. Conclusions. Interleukin-10 is an important regulator of the immune response and likely plays a role in the pathogenesis of rheumatoid arthritis. The current results suggested that Interleukin10 promoter polymorphisms were not important for development or severity of rheumatoid arthritis."

The kinetoplastid membrane protein 11, KMP-11, from Trypanosoma cruzi elicits humoral and cellular immunity in mice that protects them from infection against further parasite challenge. Objective. To characterize the expression of surface markers on dendritic cells from chronic chagasic patients and healthy individuals, in response to the KMP-11 protein from Trypanosoma cruzi and its N-terminal pepticle K1. Materials and methods. Monocyte-derived dendritic cells from seven chronic chagasic patients and seven healthy individuals were stimulated with the KIMP-11 protein and the K1 peptide. Seven days after culturing, the CD83, CD86, and HLA-DR membrane expression as well as the production of cytokines were evaluated by flow cytometry. Results. Neither KMP-11 protein nor K1 peptide elicited the expression of the maturation marker CD83 on dendritic cells of patients or healthy control individuals. Dendritic cells from chronic chagasic patients exposed to K1 and LIPS at the same time presented a significant reduction in CD86 and CD83 membrane expression in contrast to the cells exposed to LPS alone, whereas dendritic cells from healthy individuals did not show this behavior. The secretion of interleukin-12 was decreased in the cultures of dendritic cells from chronic chagasic patients but not from healthy controls. Conclusions. KIVIP-11 protein does not affect the maturation of dendritic cells, but in the presence of LIDS the K1 peptide leads to a decreased expression of CD86 and CD83 as well as interleukin-12 production, This phenomenon may be associated with an impaired T cell stimulation."

Deforestation and land use effects on micromorphological and fertility changes in acidic rainforest soils in Venezuelan Andes	SOIL & TILLAGE RESEARCH		English	Article						land use effects; deforestation; micromorphological changes; fertility changes	ORGANIC FARMING SYSTEMS; QUALITY	"With the aim of determining the impact on soil caused by deforestation and replacement by pasture in the rainforests of the Venezuelan Andes, three representative plots were selected: one under natural forest (F), another deforested (D), and the third one under pasture (P). The chemical analyses of the soils were complemented with a micromorphological study. The analysis of thin sections revealed major differences in the microstructure and porosity, as well as in the characteristics of the fine fraction and organic constituents, together with other pedological features, corroborating the different dynamics and types of soil in the natural or altered forest landscape. The change in soil use leads to the reorganization of the solid fraction, evidenced in the intensity of the processes of transference and accumulation of materials in the different soil horizons. The results confirm that the change in land use is determinant in the current fertility and evolution of the soils. The main consequences of the land-use change are: a change in the soil organic-matter cycle with a greater degree of maturation in the disturbed soils (C/N in Ah horizon: 28.5 (F); 19.8 (D); 18.4 (P)), in which moder humus from undisturbed forest soils transforms into an acidic mull in the anthropogenic disturbed ones; illuviation of organic matter and minerals appears to have occurred after deforestation (colour (dry-wet) in Ah-Bt1-Bt2 horizons: 3/2-2/2, 4/ 4-3/4, 4.5/4-3.5/4 (F); 5/4-4.5/4, 5/6-4/6, 5/6-4.5/6 (D); 4.5/4-4/3.5, 5/6-4/4, 5/6-4/4 (P)); the amount of kaolinite and the degree of browning increased gradually with deforestation; other changes observed (bioturbation, microstructure, porosity and distribution of organic constituents) may also be related to the different activity of the soil fauna in disturbed (oribatids) and undisturbed soils (worms). Thus the porosity changes in the following form: the percentage of packing voids in the surface samples decreases from a 80% in the forest soil to a 70% and 65% in deforested and pasture soils, respectively. Moreover in depth a dominance of channels in forest-soil porosity changes into an abundance of planar voids in the other two types of soils studied. (C) 2007 Elsevier B.V. All rights reserved."

Line brightnesses, line ratios and electron temperatures are examined, and their relationship with the arm-length asymmetry of the radio source is also investigated. We find that on the side of the nucleus with the shortest radio lobe, the gas covering factor is higher, and the ionization parameter is lower. The contrasts in environmental density required to explain the asymmetries in the line brightness and the radio arm-length asymmetries are in fair agreement with each other. These results add further weight to the conclusion of McCarthy, van Breugel & Kapahi - lobe distance asymmetries in powerful radio sources are the result of an asymmetry in the environmental density. We also note that the brightness of both the UV and optical continuum emission shows a similar spatial asymmetry to that shown by the line emission. While the UV continuum asymmetry can be wholly explained by the expected asymmetry in the nebular continuum, the optical continuum asymmetry cannot. We argue that, at least at optical wavelengths, the starlight and/or the scattered light must also be strongly spatially asymmetric."

Studied sections' locations vary in distance to the Chicxulub structure from distal (Agost and Caravaca, Spain), through closer (ODP Hole 1049A, Blake Nose, North Atlantic), to proximal (El Mimbral and La Lajilla, Mexico). A clear magnetic signature is associated with the fireball layer in the most distal sections, consisting of a sharp increase in susceptibility and saturation isothermal remanent magnetization (SIRM), and a decrease in remanence coercivity. Magnetic properties in these sections point to a distinctive ferrimagnetic phase, probably corresponding to the reported Mg- and Ni-rich, highly oxidized spinels of meteoritic origin. At closer and proximal sections magnetic properties are different. Although there is an increase in susceptibility and SIRM associated with a rusty layer placed on top of the siliciclastic deposit in proximal sections, and with a similar limonitic layer on top of the spherule bed that defines the boundary at Blake Nose, the magnetic properties indicate a mixture of iron oxyhydroxides dominated by fine-grained goethite. Based on previous geochemical studies at Blake Nose and new geochemical and PGE abundance measurements performed in this work at El Mimbral, this goethite-rich layer can be interpreted as an effect of diagenetic remobilization and precipitation of Fe. There is not enough evidence to assert that this Fe concentration layer at proximal sections is directly related to deposition of fine meteoritic material. Magnetic, geochemical, and iridium data reject it as a primary meteoritic phase."

Only the fixNOQPd operon is required for the establishment of an effective symbiosis; microaerobic induction of this operon is under the control of at least three transcriptional regulators, FixKf, FnrNd, and FnrNchr, belonging to the Crp/Fnr family. In this work, we describe two novel Crp/Fnr-type transcriptional regulators (StoRd and StoRf, symbiotic terminal oxidase regulators) that play differential roles in the control of key genes for nitrogen fixation. Mutations either in stoRd or stoRf enhance the microaerobic expression of both fixNOQP reiterations, increasing also the synthesis of the cbb3-type oxidase in nodules.

The Sgr MDF is found to evolve significantly from a median [Fe/H] similar to -0.4 in the core to similar to-1.1 dex over a Sgr leading arm length representing similar to 2.5-3.0 Gyr of dynamical (i. e., tidal stripping) age. This is direct evidence that there can be significant chemical differences between current dSph satellites and the bulk of the stars they have contributed to the halo. Our results suggest that Sgr experienced a significant change in binding energy over the past several gigayears, which has substantially decreased its tidal boundary across a radial range over which there must have been a significant metallicity gradient in the progenitor galaxy. By accounting for MDF variation along the debris arms, we approximate the MDF Sgr would have had several gigayears ago. We also analyze the MDF of a moving group of M giants we previously discovered toward the north Galactic cap. These objects have the opposite radial velocities to the infalling Sgr leading arm stars there, and we propose that most of them represent Sgr trailing arm stars overlapping the Sgr leading arm in this part of the sky. If so, these trailing arm stars further demonstrate the strong MDF evolution within the Sgr stream."

Patients and Methods A total of 348 patients were randomly assigned to receive XELOX (oral capecitabine 1,000 mg/m(2) bid for 14 days plus oxaliplatin 130 mg/m(2) on day 1 every 3 weeks) or FUOX ( continuous-infusion FU 2,250 mg/m(2) during 48 hours on days 1, 8, 15, 22, 29, and 36 plus oxaliplatin 85 mg/m(2) on days 1, 15, and 29 every 6 weeks). Results There were no significant differences in efficacy between XELOX and FUOX arms, which showed, respectively, median time to tumor progression (TTP; 8.9 v 9.5 months; P = .153); median overall survival (18.1 v 20.8 months; P = .145); and confirmed response rate (RR; 37% v 46%; P = .539). The safety profile of the two regimens was similar, although there were lower rates of grade 3/4 diarrhea (14% v 24%) and grade 1/2 stomatitis (28% v 43%), and higher rates of grade 1/2 hyperbilirubinemia (37% v 21%) and grade 1/2 hand-foot syndrome (14% v 5%) with XELOX versus FUOX, respectively. Conclusion This randomized study shows a similar TTP of XELOX compared with FUOX in the first-line treatment of MCRC, although there was a trend for slightly lower RR and survival. XELOX can be considered as an alternative to FUOX."

One potential drug target in the organisms that cause these diseases is sterol biosynthesis. This paper describes the design and synthesis of quinuclidine derivatives as potential inhibitors of a key enzyme in sterol biosynthesis, squalene synthase (SQS). A number of compounds that were inhibitors of the recombinant Leishmania major SQS at submicromolar concentrations were discovered. Some of these compounds were also selective for the parasite enzyme rather than the homologous human enzyme. The compounds inhibited the growth of and sterol biosynthesis in Leishmania parasites. In addition, we identified other quinuclidine derivatives that inhibit the growth of Trypanosoma brucei (the causative organism of human African trypanosomiasis) and Plasmodium falciparum (a causative agent of malaria), but through an unknown mode(s) of action."

Detection of GRB 060927 at z=5.47: Implications for the use of gamma-ray bursts as probes of the end of the dark ages	ASTROPHYSICAL JOURNAL		English	Article						cosmology : observations; gamma rays : bursts (GRB 060927)	HOST GALAXIES; LIGHT-CURVE; THEORETICAL IMPLICATIONS; COSMIC REIONIZATION; GRB AFTERGLOWS; COLUMN DENSITY; MILKY-WAY; REDSHIFT; SWIFT; EVOLUTION	"We report on follow-up observations of the gamma-ray burst GRB 060927 using the robotic ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detected 20 s after the burst, the earliest rest-frame detection of optical emission from any GRB. Spectroscopy performed with the VLT about 13 hr after the trigger shows a continuumbreak at lambda approximate to 8070 angstrom, produced by neutral hydrogen absorption at z approximate to 5.6. We also detect an absorption line at 8158 angstrom, which we interpret as Si II lambda 1260 at z = 5. 467. Hence, GRB 060927 is the second most distant GRB with a spectroscopically measured redshift. The shape of the red wing of the spectral break can be fitted by a damped Ly alpha profile with a column density with log (N-H/cm(-2)) = 22-50 +/- 0.15. We discuss the implications of thiswork for the use ofGRBs as probes of the end of the dark ages and draw threemain conclusions: (1) GRB afterglows originating from z less than or similar to 6 should be relatively easy to detect from the ground, but rapid near-infrared monitoring is necessary to ensure that they are found; (2) the presence of large H I column densities in some GRB host galaxies at z > 5 makes the use of GRBs to probe the reionization epoch via spectroscopy of the red damping wing challenging; and ( 3) GRBs appear crucial to locate typical star-forming galaxies at z > 5, and therefore the type of galaxies responsible for the reionization of the universe."

Nuclear starburst-driven evolution of the central region in NGC 6764	ASTRONOMY & ASTROPHYSICS		English	Article						ISM : jets and outflows; galaxies : active; ISM : kinematics and dynamics; ISM : individual : objects : NGC 6764 radio; lines : galaxies	H-II-REGIONS; MOLECULAR GAS; SEYFERT-GALAXIES; STAR-FORMATION; INTERSTELLAR-MEDIUM; SPIRAL GALAXIES; GALACTIC-CENTER; RADIO; CONTINUUM; BARS	"Aims. We study the CO and the radio continuum emission in an active galaxy to analyze the interplay between the central activity and the molecular gas. Methods. We present new high-resolution observations of the (CO)-C-12(1-0) and (CO)-C-12(2-1) emission lines, and 3.5 cm and 20 cm radio continuum emission in the central region of the LINER/starburst galaxy NGC 6764. Results. The galaxy has an outflow morphology in radio continuum, spatially coincident with the CO and H alpha emission, and centered slightly off the radio continuum peak at the LINER nucleus. The total molecular gas mass in the center is about 7 x 10(8) M-circle dot, using a CO luminosity to total molecular gas conversion factor that is three times lower than the standard one. (CO)-C-12(1-0) emission is found near the boundaries of the radio continuum emission cone. The outflow has a projected expansion velocity of 25 km s(-1) relative to the systemic velocity of NGC 6764. About 4 x 10(6) M-circle dot of molecular gas is detected in the outflow. The approximate location (similar to 1 kpc) of the dynamical inner Lindblad resonance has been derived from the rotation curve. The peak of the CO emission is slightly (< 200 pc) off set from the peak of the radio continuum. Conclusions. The molecular gas has most likely been ejected by the stellar winds from the recent starburst, but the CO line ratios show indication of an interaction with the AGN. The energy released by the nuclear starburst is sufficient to explain the observed outflow, even if the data cannot exclude the AGN from being the major energy source. Comparison of the outflow with hydrodynamical simulations suggests that the nuclear starburst is 3-7 Myr old and the bubble-like outflow is still confined and not freely expanding."

Pierre Auger Collaboration	Correlation of the highest-energy cosmic rays with nearby extragalactic objects	SCIENCE		English	Article							SPECTRUM	"Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron volts and the positions of active galactic nuclei (AGN) lying within similar to 75 megaparsecs. We rejected the hypothesis of an isotropic distribution of these cosmic rays with at least a 99% confidence level from a prescribed a priori test. The correlation we observed is compatible with the hypothesis that the highest-energy particles originate from nearby extragalactic sources whose flux has not been substantially reduced by interaction with the cosmic background radiation. AGN or objects having a similar spatial distribution are possible sources."

Cox proportional hazards models were used to estimate relative risks and 95% confidence intervals. There were no statistically significant associations with endometrial cancer risk for increasing quartile intakes of any of the exposure variables. However, in continuous models calibrated by using 24-hour recall values, the multivariable relative risks were 1.61 (95% confidence interval: 1.06, 2.45) per 100 g/day of total carbohydrates, 1.40 (95% confidence interval: 0.99, 1.99) per 50 units/day of total dietary glycemic load, and 1.36 (95% confidence interval: 1.05, 1.76) per 50 g/day of total sugars. These associations were stronger among women who had never used postmenopausal hormone therapy compared with ever users (total carbohydrates P-heterogeneity = 0.04). Data suggest no association of overall glycemic index, total starch, and total fiber with risk, and a possible modest positive association of total carbohydrates, total dietary glycemic load, and total sugars with risk, particularly among never users of hormone replacement therapy."

We determined the IL12B 3' UTR genotypes in a sample of 200 seronegative individuals and 260 serologically positive patients (130 with Chagasic cardiomyopathy and 130 asymptomatic). All individuals are from a Colombian region where T. cruzi infection is endemic. Genotyping was performed by the PCR-restriction fragment length polymorphism (RFLP) method. The overall distribution of the IL12B 3' UTR alleles and genotypes in seronegative compared with seropositive individuals was not statistically significant. Interestingly, we found that the IL12B 3' UTR CC genotype was significantly increased among cardiomyopathic patients when compared to asymptomatic individuals (16% versus 5%; P = 0.005; P-c = 0.015; OR = 3.39; 95% CI 1.3-9.15). In addition, we observed that the IL12B 3' UTR C allele was present at significantly higher frequency in cardiomyopathic (33% versus 22%; P = 0.008; P-c = 0.016; OR = 1.69; 95% CI 1.12-2.55) as compared to asymptomatic. Our results suggest that IL12B 3' UTR gene polymorphisms may influence the susceptibility to develop Chagasic cardiomyopathy. (C) 2007 Elsevier Masson SAS. All rights reserved."

Observational evidence suggests that the GB is our closest star formation complex, but its true nature and origin remain rather controversial. In this work we analyze the fractal structure of the stellar component of the GB. In order to do this, we tailor and apply an algorithm that estimates the fractal dimension in a precise and accurate way, avoiding both boundary and small-data set problems. We find that early OB stars ( of spectral types earlier than B4) in the GB have a fractal dimension very similar to that of the gas clouds in our Galaxy. On the contrary, stars in the GB of later spectral types show a larger fractal dimension, similar to that found for OB stars of both age groups in the local Galactic disk (LGD). This result seems to indicate that while the younger OB stars in the GB preserve the memory of the spatial structure of the cloud where they were born, older stars are distributed following a similar morphology as that found for the LGD stars. The possible causes for these differences are discussed."

This relation is compared with that obtained for a sample of ETG of the Coma Cluster, and with that obtained for a sample of perturbed S0 galaxies contained within high-density environments. Methods. Using very strict physical isolation criteria we selected a sample of 82 E and S0 galaxies from the CfA catalogue, in the redshift range 5000 km s(-1) <= cz < 10 000 km s(-1). We obtained the photometric parameters, ( re, < S Be >) and total magnitude for 21 galaxies in the B filter and for 23 in the Gunn r filter. Results. The main result we obtained is that the KR is the same for isolated galaxies and for galaxies in high- density environments or in interaction. In addition we found evidence that the intrinsic dispersion of the KR depends on the magnitude range within which the galaxies are contained (larger dispersion for larger magnitude range), and not on the degree of gravitational interaction to which these galaxies are subjected."

Multimode pulsations of the lambda bootis star 29 Cygni: The 1995 and 1996 multisite campaigns	ASTRONOMICAL JOURNAL		English	Article						stars : individual (29 Cygni); stars : oscillations	UNEQUALLY-SPACED DATA	"In this paper we present the results of multisite photometric and spectroscopic campaigns, carried out during the years 1995 and 1996, to study the pulsations of a typical lambda Bootis star, 29 Cyg. During the 1995 campaign we found well-defined multiperiodicity in 29 Cyg, which was studied in detail during a multilongitude campaign covering a 65 day time interval in 1996. The frequency analysis of the 1996 campaign's data easily revealed 11 excited low l degree modes with frequencies of oscillation ranging from 20.3 to 37.4 cycles day(-1) and mean photometric amplitudes ranging from 10.65 to 0.96 mmag in the V filter. After removing the well-identified frequencies, the discrete Fourier transform of the residuals showed excess power in the 20-40 cycle day(-1) domain, which indicates the probable existence of unresolved rich p-mode spectra with photometric V amplitudes below 0.5 mmag. We found a regular spacing of 2.41 cycles day(-1) within the modes of 29 Cyg, which was interpreted as the spacing of consecutive even and odd l-values. The asteroseismic luminosity log L/L-circle dot = 1.12, calculated from the frequency spacing, is in good agreement with the Hipparcos luminosity log L/L-circle dot = 1.16 and with luminosities from photometric and spectroscopic calibrations. Using our multicolor photometry we tentatively identified the dominant f(1) 37.425 cycle day(-1) mode as an l = 2, n = 5mode, and made radial overtone identification for all frequencies. These ranged from n 2 to 5. Analysis of the photometric data shows the long-term ( years) and probable short-term ( days) variability of amplitudes for all of these modes in 29 Cyg. Using our multicolor WBVR filter photometry, we found the wavelength dependence of the pulsation amplitudes for the five highest amplitude modes. Based on the H alpha line radial velocity observations of 29 Cyg, we detected multiperiodic radial velocity variations with frequencies of 38.36 and 29.99 cycles day(-1) and semiamplitudes of 1.0 and 0.8 km s(-1), respectively. These frequencies coincide within the errors with the photometric frequencies of the two highest amplitude modes, 37.425 and 29.775 cycles day(-1). For the highest amplitude l = 2, n= 5 mode ( 37.425 cycles day(-1)), the radial velocity-to-light amplitude ratio and velocity-to-light phase shift are equal to 2K(H alpha)/Delta V 94 km mag(-1) s(-1) and Phi(f1) = phi(Vr) - phi V = +0: 08 +/- 0.01, respectively, and are in good agreement with values for delta Scuti stars. The rich multiperiodic spectrum makes 29 Cyg a promising target for future multisite campaigns."

This work describes the K1 peptide's secondary structure and its recognition by sera from chagasic patients. Circular dichroism and NMR spectroscopy analysis revealed that the K1 peptide adopts an alpha-helical conformation. Fifty-six percent of individuals had anti-K1 and 86% anti-KMP-11 antibodies by ELISA in the chronic Chagas' group and 28 and 68% in the indeterminate Chagas' group, respectively. By contrast, no reactivity was observed in sera from healthy individuals and tuberculosis patients. Antibody response subclass specificity to the K1 peptide was IgG1 and IgG3. Taken together these results support the idea that the K1 peptide acts as a B-cell-inducer epitope during Chagas' disease. (c) 2007 Elsevier Inc. All rights reserved."

Characterization of Fasciola samples from different host species and geographical localities in Spain by sequences of internal transcribed spacers of rDNA	PARASITOLOGY RESEARCH		English	Article							RIBOSOMAL DNA-SEQUENCE; COMPLEX NEMATODA; GIGANTICA; HEPATICA; JAPAN; GENE	"In the present study, 25 samples representing Fasciola (Platyhelminthes: Trematoda: Digenea) from nine host species and 19 geographical locations in Spain were characterized genetically by sequences of the first (ITS-1) and second (ITS-2) internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA). The ITS rDNA was amplified from individual liver flukes by polymerase chain reaction (PCR), and the amplicons were sequenced directly. The lengths of the ITS-1 and ITS-2 sequences were 422 and 362 bp, respectively, for all Spanish liver fluke samples sequenced. Comparison of the ITS sequences of the Spanish Fasciola samples examined in the present study with that of Fasciola hepatica, Fasciola gigantica and the ""intermediate Fasciola"" revealed that all Spanish Fasciola samples examined represent the single species of F. hepatica, with only slight sequence variation in the ITS-2 (1/362, 0.3%) among the sequenced samples, but the sequence variation was not related to particular host species and/or geographical origins of the samples. The Spanish F. hepatica examined differed from Fasciola from elsewhere by two nucleotides in the ITS-2, which provided genetic marker for the differentiation of Spanish F. hepatica from Fasciola from other geographical localities. These results have implications for studying the population genetic structure of the Spanish F. hepatica and for the diagnosis and control of the disease it causes."

These data complement archival high-resolution data from the Hubble Space Telescope at optical and near-IR wavelengths, creating an extremely valuable data set for astronomers with a broad range of scientific interests. Our goal is to investigate the nature of the near-UV light in these objects, its relation to the circumnuclear starburst phenomenon, and the connection of this to the evolution and growth of the galaxy bulge and central black hole. In this paper we describe the near-UV morphology of the objects and characterize the near-UV emission. We estimate the size and the luminosity of the emitting regions and extract the luminosity profile. We also determine the presence of unresolved compact nuclei. In addition, the circumnuclear stellar cluster population is identified, and the contribution of the stellar clusters to the total light, at this wavelength, is estimated. The size of the sample allows us to draw robust statistical conclusions. We find that Seyfert 1 galaxies (Sy 1's) are completely dominated by their bright and compact nuclei, which remains pointlike at this resolution, while we find almost no unresolved nuclei in Seyfert 2 galaxies (Sy2's). The Seyfert types 1 and 2 are quite segregated in an asymmetry versus compactness plot. Stellar clusters are found somewhat more frequently in Sy2's (in similar to 70% of the galaxies) than in Sy1's (similar to 57%), and contribute more to the total light in Sy2's, but these two differences seem to be mostly due to the large contribution of the compact nuclei in Sy1's, as the luminosity distribution of the clusters is similar in both Seyfert types."

In the present work, we compared the effect of flavones (chrysin and luteolin) and flavonols (kaempferol, morin, isorhamnetin, and rutin) on root colonization (number of entry points and degree of root colonization) of tomato plants (Lycopersicum esculentum L.) with the effect of these flavonoids on the presymbiotic growth of these AMF, which has been reported in a recent study. With all tested AMF (Gigaspora rosea, Gigaspora margarita, Glomus mosseae, and Glomus intraradices) a correlation between the number of entry points and the percentage of root colonization was found. When the number of entry points was high, root colonization was also enhanced. Application of the flavones chrysin and luteolin and of the flavonol morin increased the number of entry points and the degree of colonization, whereas the flavonols kaempferol, isorhamnetin, and rutin showed no effect. These results show that in contrast to their effect on the presymbiotic growth of the AMF on the level of root colonization, the tested flavonoids do not exhibit a genus- and species-specificity. Moreover, comparison of our data with the data obtained by J.M. Scervino, M.A. Ponce, R. Erra-Bassells, H. Vierheilig, J.A. Ocampo, and A. Godeas. (2005a. J.

Recently, a new lineage, highly divergent from the Italian prototype, has been reported in Spain. Objective: We describe a reversetranscription, real-time PCR assay for detection of both Toscana virus genotypes. The real-time PCR uses a TaqMan (R) probe and an internal control to identify false negative results. Study design: A conserved region of the two known lineages of Toscana virus, located at the 3' end of the small segment of their genomes, was chosen to design both the primers and the probe. Results: The sensitivity of the assay was 0.0158 TICD50 per reaction of Toscana virus, equivalent to seven copies of cDNA. No other phleboviruses or RNA viruses were amplified by this specific real-time PCR. Conclusions: The assay seems to be sensitive, reliable and easy to be applied in the diagnosis of autochthonous and/or imported suspected cases of Toscana virus infection. (c) 2007 Elsevier B.V.

About 500 new variable stars enter the General Catalogue of Variable Stars (GCVS) every year. Most of them however lack spectroscopic observations, which remains critical for a correct assignement of the variability type and for the understanding of the object. Aims. The Variable Star One-shot Project (VSOP)is aimed at (1) providing the variability type and spectral type of all unstudied variable stars, (2) process, publish, and make the data available as automatically as possible, and (3) generate serendipitous discoveries. This first paper describes the project itself, the acquisition of the data, the dataflow, the spectroscopic analysis and the on-line availability of the fully calibrated and reduced data. We also present the results on the 221 stars observed during the first semester of the project. Methods. We used the high-resolution echelle spectrographs HARPS and FEROS in the ESO La Silla Observatory (Chile) to survey known variable stars. Once reduced by the dedicated pipelines, the radial velocities are determined from cross correlation with synthetic template spectra, and the spectral types are determined by an automatic minimum distance matching to synthetic spectra, with traditional manual spectral typing cross-checks. The variability types are determined by manually evaluating the available light curves and the spectroscopy. In the future, a new automatic classifier, currently being developed by members of the VSOP team, based on these spectroscopic data and on the photometric classifier developed for the COROT and Gaia space missions, will be used.

Objective: We aimed to assess the association of energy intake from fried food with general and central obesity in Spain, a Mediterranean country where frying with oil is a traditional cooking procedure. Design: This was a cross-sectional study of 33 542 Spanish persons aged 29-69 y who were participating in the European Prospective Investigation into Cancer and Nutrition between 1992 and 1996. Dietary intake was assessed by a diet history questionnaire. Height, weight, and waist circumference were measured by trained interviewers. Analyses were performed with logistic regression and were adjusted for total energy intake and other confounders. Results: The prevalence of general obesity [body mass index (in kg/m(2)) 30] was 27.6% in men and 27.7% in women. Respective figures for central obesity (waist circumference >= 102 cm in men and >= 88 cm in women) were 34.5% and 42.6%. The average proportion of energy intake from fried food was 15.6% in men and 12.6% in women. The adjusted odds ratios for general obesity in the highest versus the lowest quintile of fried food intake were 1.26 (95% CI: 1.09, 1.45; P for trend < 0.001) in men and 1.25 (1.11, 1.41; P for trend < 0.001) in women. The corresponding values for central obesity were 1.17 (1.02, 1.34; P for trend < 0.003) in men and 1.27 (1.13, 1.42; P for trend < 0.001) in women. Conclusion: Fried food was positively associated with general and central obesity only among subjects in the highest quintile of energy intake from fried food."

The data set consists of photometric time-series from eight sites using nine 0.6-2.1 m telescopes with a time-baseline of 43 d. In two stars, EW Cnc and EX Cnc, we detect the highest number of frequencies (41 and 26) detected in delta Scuti stars belonging to a stellar cluster, and EW Cnc has the second highest number of frequencies detected in any delta Scuti star. We have computed a grid of pulsation models that take the effects of rotation into account. The distribution of observed and theoretical frequencies shows that in a wide frequency range a significant fraction of the radial and non-radial low-degree modes are excited to detectable amplitudes. Despite the large number of observed frequencies we cannot constrain the fundamental parameters of the stars. To make progress we need to identify the degrees of some of the modes from either multicolour photometry or spectroscopy."

GRB 060912A and the nature of the long-short GRB divide	MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY		English	Article						gamma-rays : bursts	GAMMA-RAY BURST; HOST GALAXY; STAR-FORMATION; VLT SPECTROSCOPY; AFTERGLOW; SUPERNOVA; REDSHIFT; FAINT; PROGENITORS; GRB-050709	"We investigate the origin of the GRB 060912A, which has observational properties that make its classification as either a long or short burst ambiguous. Short-duration gamma-ray bursts (SGRBs) are thought to have typically lower energies than long-duration bursts, can be found in galaxies with populations of all ages and are likely to originate from different progenitors to the long-duration bursts. However, it has become clear that duration alone is insufficient to make a distinction between the two populations in many cases, leading to a desire to find additional discriminators of burst type. GRB 060912A had a duration of 6 s and occurred only similar to 10 arcsec from a bright, low-redshift (z = 0.0936) elliptical galaxy, suggesting that this may have been the host, which would favour it being a short burst. However, our deep optical imaging and spectroscopy of the location of GRB 060912A using the Very Large Telescope (VLT) shows that GRB 060912A more likely originates in a distant star-forming galaxy at z = 0.937, and is most likely a long burst. This demonstrates the risk in identifying bright, nearby galaxies as the hosts of given gamma-ray bursts (GRBs) without further supporting evidence. Further, it implies that, in the absence of secure identifications, 'host' type, or more broadly discriminators that rely on galaxy redshifts, may not be good indicators of the true nature of any given GRB."

Investigation is hampered by difficulty in estimating in vivo production of nitric oxide (NO), but genetic studies provide a potential means of examining the relation between NO production and disease outcome. To better characterize the host genetic factors determining the susceptibility to TB, we evaluated the influence of two polymorphisms in the NOS2A gene on the risk of developing pulmonary TB in a Northwestern Colombian population, which is a moderately-high endemic area. One hundred and fourteen patients with TB and negative for human immunodeficiency virus, plus 304 healthy controls were examined for NOS2A CCTTT and TAAA polymorphisms. A total of 160 healthy controls mentioned before, underwent tuberculin skin test (TST). Analysis disclosed significant differences between patients and controls with NOS2A CCTTT polymorphism (P = 0.0001, Pc = 0.001, OR = 0.4, and 95%Cl = 0.3-0.7) independent of TST status. When the NOS2A alleles were stratified into short (8-11) and long (12-16) repeats, significant differences with short repeats were observed between TB patients and all controls (P = 0.005, OR = 0.63, 95% Cl = 0.46-0.86). No individual association with NOS2A TAAA was detected. These results indicate that a polymorphism in the NOS2A gene influences the susceptibility to TB and suggest a role for NOS2A in the pathogenesis of mycobacterial infection. (c) 2007 Elsevier Ltd.

There is some evidence that mutations in MTHFR gene provide susceptibility to NTDs in some populations; however, other studies have not found this association. One of the problems with previous studies is that they treat NTDs as a homogeneous group, when specific defects could have different etiologies. We conducted a case-control study specifically for anencephaly, based on the Mexican Epidemiological Surveillance System of Neural Tube Defects to evaluate its association with maternal MTHFR 677C > T and 1298A > C polymorphisms, in three states with high frequencies of NTDs: Puebla, Estado de Mexico and Guerrero. We interviewed and collected blood samples from 118 case mothers and 112 control mothers. The questionnaire included information on their reproductive history, socioeconomic characteristics, prenatal care, tobacco and alcohol use, presence of chronic diseases, acute illnesses and fever, consumption of multivitamins and drugs during the periconceptional period. After adjusting for potential confounders, the risk from the mutated homozygous mothers (677TT genotype) was significantly higher than that from mothers with 677CC genotype (OR 3.16, 95 % C1 1.29-7.73); in the case of the heterozygous mothers, an increased risk of anencephaly was observed, even though this was not statistically significant (OR 1.8195% C1 0.78-4.25).

The southern, historic collapse crater (El Crater) currently hosts a fumarolic field with a maximum temperature of 121 degrees C. Chemical and isotopic data from five gas-sampling field campaigns carried out in 2002, 2003 and 2005 highlight the presence of high-temperature gas components (e.g. SO2, HCl and HF), which indicate a significant contribution of juvenile magmatic fluids to the hydrothermal system feeding the gas discharges. This is strongly supported by the mantle-derived helium and carbon isotopic signatures, although the latter is partly masked by either a sedimentary subduction-related or a shallow carbonate component. The observed chemical and isotopic composition of the Mombacho fluids seems to indicate that this volcanic system, although it has not experienced eruptive events during the last centuries, can be considered active and possibly dangerous, in agreement with the geophysical data recorded in the region. Systematic geochemical monitoring of the fumarolic gas discharges, coupled with a seismic and ground deformation network, is highly recommended in order to monitor a possible new eruptive phase."

An association study was carried out to examine the influence of MIF-173 single nucleotide polymorphism and the MIF-794 microsatellite on the susceptibility to develop human tuberculosis (TB) in a well-defined Latin-American population. To this purpose, 230 northwestern Colombian patients with pulmonary TB, negative for human immunodeficiency virus infection, and 235 matched healthy individuals stratified by the tuberculin skin test were examined. Multivariate analysis showed that MIF-173C allele was associated with disease (odds ratio = 1.64, 95% confidence interval 1.07-2.52) in a dominant pattern. No allele in the MIF-794 CATT microsatellite was associated with risk of TB. These results indicate that MIF gene influences the risk of developing TB in the studied population."

The morphologies are varied. The nebula of one source has a centrally peaked, rounded appearance. In the other two objects, it consists of two spatial components. The three nebulae are aligned with the radio axis within less than or similar to 30 degrees. The total Ly alpha luminosities are in the range (0.3-3.4) x 10(44) erg s(-1). The Ly alpha spectral profile shows strong variation through the nebulae, with full width at half-maximum (FWHM) values in the range similar to 400-1500 km s(-1) and velocity shifts V-offset similar to 120-600 km s(-1). We present an infall model that can successfully explain the morphology, size, surface brightness distribution and the velocity field of the Ly alpha nebula associated with MRC 1558-003. It can also explain why Ly alpha is redshifted relative to other emission lines and the FWHM values of the non-resonant He II line. This adds further support to our previous conclusion that the quiescent giant nebulae associated with this and other high-redshift powerful radio galaxies are in infall. A problem for this model is the difficulty to reproduce the large Ly alpha FWHM values, which might be the consequence of a different mechanism. We have discovered a giant (similar to 85 kpc) Ly alpha nebula associated with the radio galaxy MRC 0140-257 at z = 2.64. It shows strikingly relaxed kinematics (FWHM < 300 km s(-1) and V-offset less than or similar to 120 km s(-1)), unique among high-z (greater than or similar to 2) radio galaxies."

Precise stellar masses and radii provide unique information on stellar evolution. In a Galactic context, they may also provide information on the evolution of the Solar neighbourhood. Aims. We aim to determine absolute dimensions for the mid B-type eclipsing binary U Ophiuchi and compare the inferred ages and chemical compositions to those of other binary stars with masses near 5 M-circle dot. Methods. We determine masses, radii, log g, log T-eff, and luminosities for the stars in U Oph from new radial velocities and uvby light curves. By improving the Wilson-Devinney code, we also derive precise apsidal-motion and light-time orbits of this triple system, using 353 times of minimum over 120 years. Finally, we compare the data for U Oph and three similar systems with the predictions of stellar models. Results. The stars in U Oph have masses of 5.27 +/- 0.09 M-circle dot and 4.74 +/- 0.07 M circle dot, radii of 3.48 +/- 0.02 R-circle dot and 3.11 +/- 0.03 R-circle dot; we argue that systematic errors are negligible. The apsidal motion period is exceptionally short, U similar to 21 yr, while the light-time orbit has P-3 similar to 38.4 yr. The precise log g values for DI Her, UOph, V760 Sco, and MU Cas, all within 10% of 5 M-circle dot, place them successively from the ZAMS to the TAMS, at ages of 5-100 x 10(6) yr. Current stellar evolution models fit both stars in each system very well if the (otherwise unconstrained) metal abundance Z is adjusted in each case. Conclusions. More accurate data and/or binary systems with larger mass ratios are needed to actually test stellar models near 5 M-circle dot. The different Z values found for these young, nearby systems suggest that disk stars form with a range of metal abundances even today, but more data are needed to confirm this result."

Glomus mosseae and Glomus deserticola increased dry weight, shoot length, total N, P and K concentration and the quantity of chlorophyll in E. globulus shoots. The protection of Eucalyptus by AM fungi against the action of the heavy metals was more evident when this plant grew as an intercrop with soybean than as a monoculture. The presence of the saprobe fungi Fusarium concolor and Trichoderma koningii further enhanced shoot dry weight, N, P and K content of AM Eucalyptus. The co-inoculation of Eucalyptus with Glomus deserticola and T koningii was more effective for Cd uptake. In addition, Glomus deserticola enhanced the amount of Ph absorbed by Eucalyptus plants. We showed that it is important to select the most efficient AM and saprobe fungi to stimulate plant growth in heavy-metal-contaminated soil and that the combination of both plays an important role in metal tolerance of Eucalyptus plants.

Proper motions of the jets in the region of HH 30 and HL/XZ Tau: Evidence for a binary exciting source of the HH 30 jet	ASTRONOMICAL JOURNAL		English	Article						"ISM : Herbig-Haro objects; ISM : individual (HH 30, HH 266); ISM : jets and outflows; stars : formation; stars : individual (HL Tauri, XZ Tauri)"	AURIGA MOLECULAR CLOUD; HL TAURI; CIRCUMSTELLAR DISK; HIGH-RESOLUTION; HH 30; YOUNG STARS; LONG-SLIT; OUTFLOWS; SPECTROSCOPY; KINEMATICS	"We present [ S II] images of the HH 30 and HL/XZ Tau region obtained at two epochs, as well as long-slit optical spectroscopy of the HH 30 jet. We measured proper motions of similar to 100-300 km s(-1) for the HH 30 jet and counterjet and of similar to 120 km s(-1) for the HL Tau jet. Inclination angles with respect to the plane of the sky are 0 degrees - 40 degrees for the HH 30 jet and 60 degrees for the HL Tau jet. Comparison with previous observations suggests that most of the jet knots consist of persistent structures. Also, we corroborate that the HH 30-N knots correspond to the head of the HH 30 jet. The overall HH 30 jet structure can be well described by a wiggling ballistic jet, arising either from orbital motion of the jet source around a primary or from precession of the jet axis because of the tidal effects of a companion. In the first scenario, the orbital period would be 53 yr and the total mass 0.25-2 M-circle dot. In the precession scenario, the mass of the jet source would be similar to 0.1-1 M-circle dot, the orbital period < 1 yr, and the mass of the companion less than a few times 0.01 M-circle dot, thus being a substellar object or a giant exoplanet. In both scenarios a binary system with a separation < 18 AU(< 0.13"") is required. Since the radius of the flared disk observed with the HST is similar to 250 AU, we conclude that this disk appears to be circumbinary rather than circumstellar, suggesting that the search for the collimating agent of the HH 30 jet should be carried out at much smaller scales."

Squalene synthase (SQS) catalyzes the first step committed to the biosynthesis of sterols within the isoprenoid pathway, and several inhibitors of the enzyme have selective antitrypanosomal activity both in vivo and in vitro. The enzyme from Trypanosoma cruzi is a 404-amino-acid protein with a clearly identifiable membrane-spanning region. In an effort to generate soluble recombinant enzyme, we have expressed in Escherichia coli several truncated versions of T. cruzi SQS with a His tag attached to the amino terminus. Deletions of both the amino- and carboxyl-terminal regions generated active and soluble forms of the enzyme. The highest levels of soluble protein were achieved when 24 and 36 amino acids were eliminated from the amino and carboxyl regions, respectively, yielding a protein of 41.67 kDa. The Michaelis-Menten constants of the purified enzyme for farnesyl diphosphate and NAD (NADPH) were 5.25 and 23.34 mu M, respectively, whereas the V-max was 1,428.56 nmol min(-1)mg(-1). Several quinuclidine derivatives with antiprotozoal activity in vitro were found to be selective inhibitors of recombinant T. cruzi SQS in comparative assays with the human enzyme, with 50% inhibitory concentration values in the nanomolar range. These data suggest that selective inhibition of T. cruzi SQS may be an efficient strategy for the development of new antitrypanosomal agents."

The design of environmental monitoring programmes should include indicators of the current status of ecosystems, alerting to incipient changes in them. In this context, a sampling scheme has been designed taking into account the main processes and soil uses affecting the dynamics of soil organic matter. Well-tested parameters were determined in order to assess which of them are most useful as indicators of soil organic matter evolution in and soil, such as that in the ""Cabo de Gata-Nijar"" Natural Park (SE Spain). The parameters characterising the lability of the different fractions indicate changes in soil organic matter triggered by changes in soil use and soil dynamics. Changes in soil use, when drastic, are best reflected by those fractions comprising a high percentage of the total soil carbon, while the processes having slower dynamics are best demonstrated by the labile fractions. As a result of the sensitivity analysis of parameters versus changes, and taking into account the operational difficulties for determining them, the following indicators are proposed for a monitoring programme: total organic carbon, active fraction of the organic carbon and ratios of this fraction versus total organic carbon (%) (as given by the lability index proposed).

Aluminum tolerance in some plant species has been ascribed to arbuscular mycorrhizal fungal symbiosis. In this study, the application of aluminum was found to inhibit mycelia development of saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi Glomus mosseae and Glomus deserticola in vitro. Several levels of aluminum were applied to Eucalyptus globulus plants and inoculated with arbuscular mycorrhizal fungi alone or together with both saprobe fungi. The application of 1,500 mg kg(-1) decreased the shoot and root dry weight, chlorophyll content and total P, Mg, and Ca concentrations in the shoot of E. globulus. However, both mycorrhizal fungi G. mosseae and G. deserticola inoculated alone increased the shoot dry weight of Eucalyptus, compared with a non- arbuscular mycorrhizal inoculated control treated with 1,500 mg kg(-1) of aluminum. When 1,500 mg kg(-1) of aluminum was applied, T. koningii increased the effect of G. deserticola on the shoot weight of eucalyptus, whereas with 3,000 mg kg(-1), shoot weight and arbuscular mycorrhizal colonization decreased in all treatments. With 1,500 mg kg(-1), the highest accumulation of aluminum in the shoot was obtained when G. deserticola was inoculated together with T. koningii. The possibility of manipulating an arbuscular mycorrhizal inoculation together with a saprobe fungus confers a high aluminum resistance in E. globulus. The effect of such combined inoculation is particularly important in some Chilean volcanic acid soils, mainly those which have been intensively cropped and are without lime addition, which facilitates the increase of phytotoxic aluminum species and limits their agricultural use. Therefore, such dual inoculation in field conditions deserves further investigation. Overall, the arbuscular mycorrhizal and saprobe fungi contribute to the increase in resistance of E. globulus to aluminium."

After correction by misclassification, near-infrared spectroscopy was associated with an odds ratio of 2.3 (95% confidence interval: 1.36, 4.22). The amount of PTCA is thus a strong and independent risk indicator for melanoma. Incorporating PTCA determination into epidemiologic studies is therefore recommended."

We determined the nature and Peimbert type of two low-excitation planetary nebulae, PNG 232.0+05.7 and IRAS 19336-0400. Methods. We used low resolution optical spectroscopy in the range 3200-9000 angstrom. Results. We derived line intensities, reddening, physical conditions ( electron density and temperature) and ionic and elemental abundances. Based on the abundance analysis and its radial velocity we conclude that PNG 232.0+05.7 is a halo planetary nebulae. This discovery thus adds this object to the sample of ten known halo planetary nebulae. IRAS 19336-0400 is probably a type III planetary nebulae, as strongly suggested by its abundances and high radial velocity, although this conclusion awaits a better estimation of its distance."

Testing the predicted mass-loss bi-stability jump at radio wavelengths	ASTRONOMY & ASTROPHYSICS		English	Article						"radio continuum : stars; stars : early-type; stars : mass-loss; stars : winds, outflows"	EARLY-TYPE STARS; RADIATION-DRIVEN WINDS; LUMINOUS BLUE VARIABLES; LOW METALLICITY ENVIRONMENT; SOUTHERN OB STARS; STELLAR WINDS; WOLF-RAYET; SPECTRAL CLASSIFICATIONS; CONTINUUM MEASUREMENTS; TERMINAL VELOCITIES	"Context. Massive stars play a dominant role in the Universe, but one of the main drivers for their evolution, their mass loss, remains poorly understood. Aims. In this study, we test the theoretically predicted mass-loss behaviour as a function of stellar effective temperature across the so-called ""bi-stability"" jump. Methods. We observe OB supergiants in the spectral range O8-B3 at radio wavelengths to measure their thermal radio flux densities, and complement these measurements with data from the literature. We derive the radio mass-loss rates and wind efficiencies, and compare our results with H alpha mass-loss rates and predictions based on radiation-driven wind models. Results. The wind efficiency shows the possible presence of a local maximum around an effective temperature of 21 000 K - in qualitative agreement with predictions. Furthermore, we find that the absolute values of the radio mass-loss rates show good agreement with empirical H alpha rates derived assuming homogeneous winds - for the spectral range under consideration. However, the empirical mass-loss rates are larger ( by a factor of a few) than the predicted rates from radiation-driven wind theory for objects above the bi-stability jump ( BSJ) temperature, whilst they are smaller ( by a factor of a few) for stars below the BSJ temperature. The reason for these discrepancies remains as yet unresolved. A new wind momenta-luminosity relation ( WLR) for O8-B0 stars has been derived using the radio observations. The validity of the WLR as a function of the fitting parameter related to the force multiplier alpha(eff) ( Kudritzki & Puls 2000) is discussed. Conclusions. Our most interesting finding is that the qualitative behaviour of the empirical wind efficiencies with effective temperature is in line with the predicted behaviour, and this presents the first hint of empirical evidence for the predicted mass-loss bi-stability jump. However, a larger sample of stars around the BSJ needs to be observed to confirm this finding."

Among these mechanisms, modifications in the ratio of saturated/unsaturated fatty acids and in cis/trans fatty acid isomers, cyclopropanation and changes in the phospholipids head group composition have been observed. To further understand the role of phospholipid head groups in solvent stress adaptation, we knocked out the cls (cardiolipin synthase) gene in Pseudomonas putida DOT-T1E. As expected, cis mutant membranes contained less cardiolipin than those of the wild-type strain. Although no significant growth rate defect was observed in the cis mutant compared with the wild-type strain, mutant cells were significantly smaller than the wild-type cells. The cls mutant was more sensitive to toluene shocks and to several antibiotics than the parental strain, suggesting either that the RND efflux pumps involved in the extrusion of these drugs were not working efficiently or that membrane permeability was altered in the mutant. Membranes of the cis mutant strain seemed to be more rigid than those of the parental strain, as observed by measurements of fluorescence polarization using the DPH probe, which intercalates into the membranes. Ethidium bromide is pumped out in Pseudomonas putida by at least one RND efflux pump involved in antibiotic and solvent resistance, and the higher rate of accumulation of ethidium bromide inside mutant cells indicated that functioning of the efflux pumps was compromised as a consequence of the alteration in phospholipid head group composition."

For short and long-term evaluations, two sites were chosen in a private extensive cattle ranch: (1) unburned areas and (2) burned areas. The forage total cover before fire (initial stage) was 54%; this cover decreased in burned areas to 13% (1986) and to 25% (2000), mainly due to a reduction in forage shrub cover. The cover of Atriplex lampa (zampa), the dominant forage shrub, decreased from 17.0 to 0.20% in 1986 after fire, and 15 years later this value remains constant (0.33%). The same area showed a carrying capacity, expressed in hectares per large stock unit (LSU), of 10 haLSU(-1) by 1986 and 17 haLSU(-1) by 2000, whereas in unburned areas it was 7 haLSU(-1), similar to prewildfire. All selected species that had been cut, simulating the action of fire, resprouted 1 year later, except zampa. We determined that the re-establishment of zampa plants in burned areas is extremely slow. Conditions as absence of adventitious bud/root crown and drought in following post-fire years may have determined the poor recovery of A. lampa."

Searching for signatures of stochastic excitation in stellar pulsations: a look at gamma Doradus stars	ASTRONOMY & ASTROPHYSICS		English	Article						methods : statistical; stars : statistics; stars : oscillations; stars : fundamental parameters	FREQUENCY RATIO METHOD; VARIABLE-STARS; DELTA-SCUTI; CLUSTER; DOZEN	"In stellar oscillations, the temporal variation in the amplitude of a given mode can yield some information about the interior of the star. In what concerns the excitation mechanism, it has been shown that for oscillations that are excited and damped by a physical process in stochastic equilibrium, the ratio of the standard deviation of the amplitude sigma(A) over the amplitude mean value mu(A) is of the order of 0.52. This ""statistical signature"" is a general property of stochastically excited oscillations, so it can be used with any type of star-making it a powerful tool. Although the method is simple, its reliability and robustness have yet to be proven. With the help of simulations, these points are addressed in the present work, and the observational requirements for this method to work are more clearly defined. We show that a number of amplitude measurements of about 10(2) are required to get a good estimate of sigma(A)/mu(A). The method is also tested against the complication of having a time series crowded with many modes (unresolvable in short time series), and results show that the theoretical relation of sigma(A)/mu(A) still holds true. Some of the motivation behind the new tests of the method involves applying it to gamma Doradus stars. The open question of what drives oscillations in these stars makes this statistical method very interesting when applied to gamma Doradus stars. A test of the method is performed using. Doradus observations. As expected, the results are inconclusive and demonstrate how ground-based observations of. Doradus stars hardly fulfill the applicability requirements of the method. We show, however, how a possible scenario of stochastic excitation in these stars could be detected with the COROT space mission."

Various pristine sites like the Paracou Research Station are devoted to study this tropical ecosystem. We used culture-independent techniques, like polymerase chain reaction-temperature gradient gel electrophoresis, and construction of clone libraries of partial 16S rRNA and nifH genes, to analyze the composition of the bacterial community in the rhizosphere of mature trees of Eperua falcata and Dicorynia guianensis, both species within the Caesalpiniaceae family. E. falcata is one of the more abundant pioneer tree species in this ecosystem and so far, no root nodules have ever been found. However, its nitrogen-fixing status is regarded as ""uncertain"", whereas D. guianensis is clearly considered a non-nitrogen- fixing plant. The rhizospheres of these mature trees contain specific bacterial communities, including several currently found uncultured microorganisms. In these communities, there are putative nitrogen-fixing bacteria specifically associated to each tree: D. guianensis harbors several Rhlzoblum spp. and E. falcata members of the genera Burkholderla and Bradyrhizobium. In addition, nifH sequences in the rhizosphere of the latter tree were very diverse. Retrieved sequences were related to bacteria belonging to the alpha(-), beta(-), and gamma-Protcobacteria in the E. falcata rhizoplane, whereas only two sequences related to y-Proteobacteria were found in D. guianensis. Differences in the bacterial communities and the abundance and diversity of nijli sequences in E. falcata rhizosphere suggest that this tree could obtain nitrogen through a nonnodulating bacterial interaction."

These Ly alpha-excess objects (LAEs) show Ly alpha/He II values consistent with or above standard photoionization model predictions. We reject with confidence several scenarios to explain the unusual strength of Ly alpha in these objects: shocks, low nebular metallicities, high gas densities and absorption/ scattering effects. We show that the most successful explanation is the presence of a young stellar population which provides the extra supply of ionizing photons required to explain the Ly alpha excess in at least the most extreme LAEs ( probably in all of them). This interpretation is strongly supported by the tentative trend found by other authors for z >= 3 radio galaxies to show lower ultraviolet rest-frame polarization levels, or the dramatic increase in the detection rate at submm wavelengths of z > 2.5 radio galaxies. The enhanced star formation activity in LAEs could be a consequence of a recent merger which has triggered both the star formation and the active galactic nucleus/radio activities. The measurement of unusually high Ly alpha ratios in the extended gas of some high-redshift radio galaxies suggests that star formation activity occurs in spatial scales of tens of kpc. We argue that, although the fraction of LAEs may be incompletely determined, both at 2 less than or similar to z < 3 and at z >= 3, the much larger fraction of LAEs found at z >= 3 is a genuine redshift evolution and not due to selection effects. Therefore, our results suggest that the radio galaxy phenomenon is more often associated with a massive starburst at z > 3 than at z < 3."

Our sample consists of 11 radio galaxies at 2.3 <= z <= 3.6 previously known to have giant, kinematically quiescent nebulae. We identify several correlated asymmetries: on the side of the brightest radio jet and hotspot (i) the redshift of the kinematically quiescent nebula is highest, (ii) Ly alpha is brighter relative to the other lines and continuum, (iii) the radio spectrum is flattest and (iv) the radio structure has its highest polarization. These asymmetries are not found to be correlated with either the radio arm length asymmetry or the brightness asymmetry of the UV-optical emitting material. The correlation between the radio brightness asymmetry and the radial velocity of the quiescent gas also appears to be present in powerful radio galaxies with 0 less than or similar to z less than or similar to 1. Collectively, these asymmetries are most naturally explained as an effect of orientation, with the quiescent nebulae in infall: this is the first study to distinguish between the rotation, infall, outflow and chaotic motion scenarios for the kinematically quiescent emission-line nebulae around powerful active galactic nuclei."

The evolution of the angular momentum in young low-mass stars is still a debated issue. The stars presented here were discovered as X-ray sources in the ROSAT All-Sky Survey (RASS) of the Orion complex and subsequently optically identified thanks to both low and high resolution spectroscopy. Aims. The determination of the rotational periods in young low-mass stars of different age is fundamental for the understanding of the angular momentum evolution. Methods. We performed a photometric monitoring program on a sample of 40 solar-mass young stars in the Orion star-forming region, almost all previously identified as weak T Tauri stars (WTTS) candidates. Photometric B and V data were collected from 1999 to 2006 at Catania Astrophysical Observatory (OAC). Data were also acquired in December 1998 at Calar Alto Observatory (CA) and in 1999, 2000, and 2003 at San Pedro Martir (SPM). From the observed rotational modulation, induced by starspots, we derived the rotation periods, using both the Lomb-Scargle periodogram and the CLEAN deconvolution algorithms. Results. In total, we were able to determine the rotation periods for 39 stars, spanning from about 0.5 to 13 days, showing a rather flat distribution with a peak around 1-2 days. Though some of these stars were found to be spectroscopic binaries, only the systems with shorter orbital periods and circular orbits turned out to be synchronized. In the other cases, the rotational period is shorter than the period of pseudo-synchronization at periastron. Conclusions. The new data provide further evidence for the spin up of solar-mass stars predicted by models of angular momentum evolution of pre-main sequence (PMS) stars."

The measurement of the fractal dimension (D-f) of interstellar clouds is a simple way to characterize this fractal structure, but several factors, both intrinsic to the clouds and to the observations, may contribute to affect the values obtained. In this work, we study the effects that opacity and noise have on the determination of D-f. We focus on two different fractal dimension estimators, namely, the perimeter-area-based dimension (D-per) and the mass-size dimension (D-m). We first use simulated fractal clouds to show that opacity does not affect the estimation of D-per. However, D-m tends to increase as opacity increases, and this estimator fails when applied to optically thick regions. In addition, very noisy maps can seriously affect the estimation of both D-per and D-m, decreasing the final estimation of D-f. We apply these methods to emission maps of the Ophiuchus, Perseus, and Orion molecular clouds in different molecular lines, and we obtain that the fractal dimension is always in the range 2.6 less than or similar to D-f less than or similar to 2.8 for these regions. These results support the idea of a relatively high (>2.3) average fractal dimension for the interstellar medium, as traced by different chemical species."

Recent findings suggest that interferon regulatory factor 5 (IRF-5) may play a crucial role in several cellular processes, including the transcription of genes for inflammatory cytokines. Two genetic variants of the IRF5 gene (rs2004640 in exon 1 and rs2280714 in the 3'-untranslated region) have been shown to exert functional modifications affecting IRF5 messenger RNA splicing and expression, and have been associated with genetic predisposition to systemic lupus erythematosus (SLE). The aim of this study was to analyze the possible contribution of the IRF5 gene to the predisposition to rheumatoid arthritis (RA). Methods. Three case-control cohorts from Spain (724 RA patients and 542 healthy controls), Sweden (281 RA patients 474 healthy controls), and Argentina (284 RA patients and 286 healthy controls) were independently analyzed. Genotyping for IRF5 rs2004640 and rs2280714 was performed using a TaqMan 5' allele-discrimination assay. Results. In the 3 cohorts studied, no statistically significant differences in allele or genotype frequencies of the rs2004640 and rs2280714 IRF5 polymorphisms were observed between RA patients and controls. Accordingly, haplotype analysis revealed that none of the IRF5 haplotypes was associated with genetic predisposition to RA. Conclusion. Our results suggest that the IRF5 functional polymorphisms analyzed do not seem to be implicated in genetic susceptibility to RA."

Detection of HCO+ emission toward the planetary nebula K3-35	ASTRONOMICAL JOURNAL		English	Article						circumstellar matter; ISM : molecules; planetary nebulae : general; radio lines : ISM; stars : individual (K3-35)	ASYMPTOTIC GIANT BRANCH; WATER-MASER EMISSION; RADIO MORPHOLOGY; CO; ENVELOPES; STARS	"We report the detection, for the first time, of HCO+(J = 1 -> 0) emission, as well as marginal CO(J = 1 -> 0) emission, toward the planetary nebula (PN) K3-35 as a result of a molecular survey carried out toward this source. We also report new observations of the previously detected CO( J 2 ! 1) and water maser emission, as well as upper limits for the emission of the SiO, (HCO+)-C-13, HNC, HCN, HC3OH, HC5N, CS, HC3N, (CO)-C-13, CN, and NH3 molecules. From the ratio of CO(J = 2 -> 1) to CO(J = 1 -> 0) emission we have estimated the kinetic temperature of the molecular gas, obtaining a value of similar or equal to 20 K. Using this result we have estimated a molecular mass for the envelope of similar or equal to 0.017M(circle dot) and an HCO+ abundance relative to H-2 of 6 x 10(-7), similar to the abundances found in other PNe. K3-35 is remarkable because it is one of the two PNe reported to exhibit water maser emission, which is present in the central region, as well as at a distance of similar or equal to 5000 AU from the center. The presence of molecular emission provides some clues that could help in understanding the persistence of water molecules in the envelope of K3-35. The HCO+ emission could be arising in dense molecular clumps, which may provide the shielding mechanism that protects water molecules in this source."

We continue our survey of magnetic chemically peculiar (CP2) stars in galactic open clusters to shed more light on their origin and evolution. Aims. To study the group of CP2 stars, it is essential to find these objects in different galactic environments and at a wide range of evolutionary stages. The knowledge of open cluster ages and metallicities can help for finding a correlation between these parameters and the (non-)presence of peculiarities, which has to be taken into account in stellar evolution models. Methods. The intermediate band. a photometric system samples the depth of the 5200 angstrom flux depression by comparing the flux at the centre with the adjacent regions with bandwidths of 110 angstrom to 230 angstrom. It is capable of detecting magnetic CP2 and CP4 stars with high efficiency, but also the groups of (metal-weak) lambda Bootis and classical Be/shell stars can be successfully investigated. In addition, it allows the age, reddening, and distance modulus to be determined with appropriate accuracy by fitting isochrones. Results. From the 1677 observed members of the eight open clusters, one Ae and twenty-five CP2 stars were identified. Furthermore nineteen deviating stars are designated as questionable for several reasons. The estimated age, reddening, and distance for the programme clusters were compared with published values of the literature and discussed in this context. Conclusions. The current paper shows that CP2 stars are continuously present in very young (7 Myr) to intermediate age (500 Myr) open clusters at distances greater than 2 kpc from the Sun."

The effect of NO3- or NH4+ on mycorrhizal and non-mycorrhizal wheat plants was measured on key root-soil interface activities: pH, acid phosphatase (P-ase) activity and P availability. Root AM colonization, extraradical mycelium length and spore number were also examined at three stages of AM symbiosis development (120, 150 and 240 days after sowing, DAS). The effect of N-source on AM propagule formation was used as an index of the quality and vigor of AM colonization. Mycorrhizal root length was greater with NO3- than with NH4+ at all times. The NO3- source also improved extraradical mycelium density, which reached its maximum at 150 DAS. At each harvest the spore number in the rhizosphere soil was also greater with NO3- fertilization. This NO3- effect on spore formation ranged from 20% at a 120 DAS to 287% at a 240 DAS increase, compared with NH4+. Extraradical mycelium and AM efficiency for P acquisition appeared to be related. The particular fungus/plant metabolism as affected by N sources (NO3- or NH4+) applied did not result in differential plant growth or in changes in N plant acquisition, but affected AM development and activity. Differences in soil pH, available P or P-ase activity in soil seems not to be responsible for the improved physiological status of mycorrhizal development in NO3- fed plants. Mycorrhizal propaguide formation in this soil and the high persistence of extraradical mycelium are important factors which may have a strong influence on the next crop, and thus, this aspects should be considered when a cropping system is designed. The influence of N sources on AM performance is of ecological and practical interest in volcanic soils when conventional management is used. (c) 2006 Elsevier B.V. All rights reserved."

Distinctive features of the symbiosis between alfalfa and S. meliloti are the marked specificity from the plant to the bacteria and the strict requirement for the presence of sulfated lipochitooligosaccharides (Nod factors [NFs]) at its reducing end. Here, we present evidence of the presence of a functional nodH-encoded NF sulfotransferase in the Or191-like rhizobia. The nodH gene, present in single copy, maps to a high molecular weight megaplasmid. As in S. meliloti, a nodF homolog was identified immediately upstream of nodH that was transcribed in the opposite direction (local synteny). This novel nodH ortholog was cloned and shown to restore both NF sulfation and the Nif(+)Fix(+) phenotypes when introduced into an S. meliloti nodH mutant. Unexpectedly, however, nodH disruption in the Or191-like bacteria did not abolish their ability to nodulate alfalfa, resulting instead in a severely delayed nodulation. In agreement with evidence from other authors, the nodH sequence analysis strongly supports the idea that the Or191-like rhizobia most likely represent a genetic mosaic resulting from the horizontal transfer of symbiotic genes from a sinorhizobial megaplasmid to a not yet clearly identified ancestor."

Rheumatoid arthritis (RA) is considered a Th1-driven disease. Interleukin 4 (IL-4) binds to its receptor, promoting Th2 differentiation and limiting Th1 responses, but its role in the pathogenesis of RA is conflicting. We analyzed 2 polymorphisms of the IL4 gene and 4 polymorphisms of the IL4RA gene in patients with RA and in a control population, as well as rheumatoid factor (RF) seropositivity, titers of RF, and history of replacement joint surgery among patients with RA. Methods. The study population consisted of 102 patients with RA and 102 matched healthy controls. Genotyping of IL4-590, IL4RA +148, +1124, +1218, and +1902 was determined by restriction fragment length polymorphism-polymerase chain reaction (PCR) and sequence-specific primer-PCR. IL4 variable number tandem repeat polymorphism was determined by direct amplification. Results. The IL4-590TT genotype was significantly more frequent in patients with RA than in controls (p = 0.018, OR 3.34, 95% CI 1.08-11.04). The IL4RA +148A allele was significantly associated with the presence of RF (p = 0.0019, OR 2.55, 95% CI 1.55-4.86) and a history of articular joint replacement (p = 0.024, OR 2.08, 95% CI 1.04-4.18). The IL4RA +19026 allele was more frequently seen in patients with RA and high RF titers (p = 0.00067, OR 4, 95% CI 1.64-9.93). Conclusion. Highly complex pathways lead to the development of RA and may not be similar in all patients. Our findings of higher frequency of IL4 and IL4RA genotypes and alleles with RA, presence of RF, RF titers, and history of articular joint replacement support the polygenic expression of RA and the likely role of IL-4 in influencing its initiation and development."

Our goal is to establish the true nature of post-AGB star candidates and to identify new post-AGB stars. Methods. We used low resolution optical spectroscopy and we compared the spectra of the candidate post-AGB stars with those of stars in the library specta available in the literature and with spectra of ""standard"" post-AGB stars, and direct imaging in narrow-band filters. Results. Spectra were obtained for 16 objects: 14 objects have not been observed previously and 2 objects are already known post-AGB stars used as ""standards"" for identification. From the spectra we identify: six new post-AGB stars with spectral types between G5 and F5, two HII regions the morphology of which is revealed in the direct images for the first time, a G giant with infrared emission, a young stellar object, a probable post-AGB star with emission lines and three objects for which the classification is still unclear. As a whole, our results provide new, reliable identifications for 10 objects among listed post-AGB star candidates."

The origin of X-ray Flashes (XRFs) is still a mystery and several models have been proposed. To disentangle among these models, an important observational tool is the measure of the XRF distance scale, so far available only for a few of them. Aims. In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. Methods. We performed a detailed spectral and temporal analysis of both the prompt and the afterglow emission and we estimated the distance scale of the likely host galaxy. We then used the currently available sample of XRFs with known distance to discuss the connection between XRFs and classical Gamma-ray Bursts (GRBs). Results. We found that the prompt emission properties unambiguously identify this burst as an XRF, with an observed peak energy of E-p = 17 +/- 13 keV and a burst fluence ratio S2-30 keV/S30-400 keV > 1. A non-fading optical source with R similar to 24 mag and with an apparently extended morphology is spatially consistent with the X-ray afterglow, likely the host galaxy. XRF 040912 is a very dark burst since no afterglow optical counterpart is detected down to R > 25 mag (3 sigma limiting magnitude) at 13.6 h after the burst. The host galaxy spectrum detected from 3800 angstrom to 10 000 angstrom, shows a single emission line at 9552 angstrom. The lack of any other strong emission lines blue-ward of the detected one and the absence of the Ly alpha cut-off down to 3800 angstrom are consistent with the hypothesis of the [OII] line at redshift z = 1.563 +/- 0.001. The intrinsic spectral properties rank this XRF among the soft GRBs in the E-peak-E-iso diagram. Similar results were obtained for most XRFs at known redshift. Only XRF 060218 and XRF 020903 represent a good example of instrinsic XRF (i-XRF) and are possibly associated with a different progenitor population. This scenario may call for a new definition of XRFs."

The standard 'collapsar' model(3) predicts that a broad-lined and luminous type Ic core-collapse supernova accompanies every long- duration GRB(4). This association has been confirmed in observations of several nearby GRBs(5-9). Here we report that GRB 060505 ( ref. 10) and GRB 060614 ( ref. 11) were not accompanied by supernova emission down to limits hundreds of times fainter than the archetypal supernova SN 1998bw that accompanied GRB 980425, and fainter than any type Ic supernova ever observed(12). Multi-band observations of the early afterglows, as well as spectroscopy of the host galaxies, exclude the possibility of significant dust obscuration and show that the bursts originated in actively star-forming regions. The absence of a supernova to such deep limits is qualitatively different from all previous nearby long- duration GRBs and suggests a new phenomenological type of massive stellar death."

A log N-HI=22.6 damped Ly alpha absorber in a dark gamma-ray burst: The environment of GRB 050401	ASTROPHYSICAL JOURNAL		English	Article						"dust, extinction; galaxies : high-redshift; galaxies : ISM; gamma rays : bursts; quasars : absorption lines; X-rays : general"	HIGH COLUMN DENSITY; HOST GALAXIES; LYMAN-ALPHA; LOW METALLICITY; INTERSTELLAR-MEDIUM; ABSORPTION SYSTEMS; DUST PROPERTIES; STAR-FORMATION; LOW-REDSHIFT; NEUTRAL GAS	"The optical afterglow spectrum of GRB 050401 (at z = 2.8992 +/- 0.0004) shows the presence of a damped Ly alpha absorber (DLA), with log N-Hi 22.6 +/- 0.3. This is the highest column density ever observed in a DLA and is about 5 times larger than the strongest DLA detected so far in any QSO spectrum. From the optical spectrum, we also find a very large Zn column density, implying an abundance of [Zn/H] = -1.0 +/- 0.4. These large columns are supported by the early X-ray spectrum from Swift XRT, which shows a column density (in excess of Galactic) of log N-H = 22.21(-0.08)(+0.06) assuming solar abundances (at z = 2.9). The comparison of this X-ray column density, which is dominated by absorption due to alpha-chain elements, and the H I column density derived from the Ly alpha absorption line allows us to derive a metallicity for the absorbing matter of [alpha/H] = -0.4 +/- 0.3. The optical spectrum is reddened and can be well reproduced with a power law with SMC extinction, where A(V) = 0.62 +/- 0.06. But the total optical extinction can also be constrained independent of the shape of the extinction curve: from the optical to X-ray spectral energy distribution, we find 0.5 less than or similar to A(V) less than or similar to 4.5. However, even this upper limit, independent of the shape of the extinction curve, is still well below the dust column that is inferred from the X-ray column density, i.e., A(V) = 9.1(-1.5)(+1.4). This discrepancy might be explained by a small dust content with high metallicity (low dust-to-metals ratio). ""Gray"" extinction cannot explain the discrepancy, since we are comparing the metallicity to a measurement of the total extinction (without reference to the reddening). Little dust with high metallicity may be produced by sublimation of dust grains or may naturally exist in systems younger than a few hundred megayears."

Multifrequency variability of the blazar AO 0235+164 - The WEBT campaign in 2004-2005 and long-term SED analysis	ASTRONOMY & ASTROPHYSICS		English	Article						galaxies : active; galaxies : BL Lacertae objects : general; galaxies : BL Lacertae objects : individual : AO 0235+164; galaxies : jets; galaxies : quasars : general	ACTIVE GALACTIC NUCLEI; BL-LACERTAE OBJECTS; EXTRAGALACTIC RADIO-SOURCES; XMM-NEWTON OBSERVATIONS; SOFT-X-RAY; RELATIVISTIC JETS; LIGHT CURVES; HELICAL JETS; QUASARS; AO-0235+164	"Aims. A huge multiwavelength campaign targeting the blazar AO0235+164 was organized by the Whole Earth Blazar Telescope (WEBT) in 2003 - 2005 to study the variability properties of the source. Methods. Monitoring observations were carried out at cm and mm wavelengths, and in the near-IR and optical bands, while three pointings by the XMM-Newton satellite provided information on the X-ray and UV emission. Results. We present the data acquired during the second observing season, 2004 - 2005, by 27 radio-to-optical telescopes. The similar to 2600 data points collected allow us to trace the low-energy behaviour of the source in detail, revealing an increased near-IR and optical activity with respect to the previous season. Increased variability is also found at the higher radio frequencies, down to similar to 15 GHz, but not at the lower ones. While the X-ray (and optical) light curves obtained during the XMM-Newton pointings reveal no significant short-term variability, the simultaneous intraday radio observations with the 100 m telescope at Effelsberg show flux-density changes at 10.5 GHz, which are more likely due to a combination of intrinsic and extrinsic processes. Conclusions. The radio ( and optical) outburst predicted to peak around February - March 2004 on the basis of the previously observed 5 - 6 yr quasi-periodicity did not occur. The analysis of the optical light curves reveals now a longer characteristic time scale of variability of similar to 8 yr, which is also present in the radio data. The spectral energy distributions corresponding to the XMM-Newton observations performed during the WEBT campaign are compared with those pertaining to previous pointings of X-ray satellites. Bright, soft X-ray spectra can be described in terms of an extra component, which appears also when the source is faint through a hard UV spectrum and a curvature of the X-ray spectrum. Finally, there might be a correlation between the X-ray and optical bright states with a long time delay of about 5 yr, which would require a geometrical interpretation."

The detection of magnetic chemically peculiar (CP2) stars in open clusters of extragalactic systems can give observational answers to many unsolved questions. For example, one can study the influence of different global as well local environments on the lack of and presence of peculiarities. Aims. The mean percentage of CP2 stars in the Milky Way is of the order of 5% for the spectral range from early B-to F-type, luminosity class V objects. The origin of the CP2 phenomenon seems to be closely connected to the overall metallicity and global magnetic field environment. The theoretical models are still only tested by observations in the Milky Way. It is therefore essential to provide high quality observations in rather different global environments. Methods. The young clusters NGC 2136/7 were observed in the. a photometric system. This intermediate band photometric system samples the depth of the 520 nm flux depression by comparing the flux at the center with the adjacent regions with bandwidths of 11 nm to 23 nm. The Delta a photometric system is most suitable for detecting CP2 stars with high efficiency, but is also capable of detecting a small percentage of non-magnetic CP objects. Furthermore, the groups of (metal-weak) lambda Bootis, as well as classical Be/shell stars, can be successfully investigated. Results. We present high precision photometric. a observations of 417 objects in NGC 2136/7 and its surrounding field, of which five turned out to be bona fide magnetic CP stars. In addition, we discovered two Be/Ae stars. Conclusions. From our investigations of NGC 1711, NGC 1866, NGC 2136/7, their surroundings, and one independent field of the LMC population, we derive an occurrence of classical chemically peculiar stars of 2.2(6)% in the LMC, which is only half the value found in the Milky Way. The mass and age distribution of the photometrically detected CP stars is not different from that of similar objects in galactic open clusters."

(1999, Rev. Mex. Astron. Astrofis., 35, 187) and representative of the population of bright LINER sources. The nuclear X-ray morphology has been classified by their nuclear compactness in the hard band (4.5 - 8.0 keV) into 2 categories: active galactic nuclei (AGN) candidates ( with a clearly identified unresolved nuclear source) and starburst (SB) candidates ( without a clear nuclear source). Sixty percent of the total sample are classified as AGNs, with a median luminosity of L-X(2-10 keV) = 2.5 x 10(40) erg s(-1), which is an order of magnitude higher than for SB-like nuclei. The spectral fitting allows us to conclude that most of the objects need a non-negligible power-law contribution. When no spectral fitting can be performed ( data with a low signal-to-noise ratio), the color - color diagrams allow us to roughly estimate physical parameters, such as column density, temperature of the thermal model, or spectral index for a power-law, and therefore to better constrain the origin of the X-ray emission. The X-ray morphology, the spectra, and the color - color diagrams together allow us to conclude that a high percentage of LINER galaxies, at least approximate to 60%, could host AGN nuclei, although contributions from high-mass X-ray binaries or ultra-luminous X-ray sources cannot be ruled out for some galaxies."

Before the launch of the Swift satellite, the majority of the gamma-ray burst (GRB) afterglows for which Lya was redshifted into the observable spectrum showed evidence for a damped Lya absorber. This small sample indicated that GRBs explode either in galaxies, or regions within them, having high neutral hydrogen column densities. Aims. To increase the spectroscopic sample of GRBs with z > 2 and hence establish the N(H I) distribution along GRB lines-of-sight. Methods. We have obtained six z > 2 GRB afterglow spectra and fitted the Lya absorption line in each case to determine N(H I). This has been complemented with 12 other Swift N(H I) values from the literature. Results. We show that the peak of the GRB N(H I) distribution is qualitatively consistent with a model where GRBs originate in Galactic-like molecular clouds. However, a systematic difference, in particular an excess of low column-density systems compared to the predictions, indicates that selection effects and conditions within the cloud (e.g. strong ionization) influence the observed N(H I) range. We also report the discovery of Lya emission from the GRB 060714 host, corresponding to a star-formation rate of approximately 0.8 M-circle dot yr(-1). Finally, we present accurate redshifts of the six bursts: z = 3.240 +/- 0.001 (GRB 050319), z = 2.198 +/- 0.002 (GRB 050922C), z = 3.221 +/- 0.001 (GRB 060526), z = 3.425 +/- 0.002 (GRB 060707), z = 2.711 +/- 0.001 (GRB 060714) and z = 3.686 +/- 0.002 (GRB 060906)."

The two Titan stellar occultations of 14 November 2003	JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS		English	Article							UPPER-ATMOSPHERE; ZONAL WINDS; STRATOSPHERE; NEPTUNE; TEMPERATURE	"[1] We report the observation of two stellar occultations by Titan on 14 November 2003, using stations in the Indian Ocean, southern Africa, Spain, and northern and southern Americas. These occultations probed altitudes between similar to 550 and 250 km ( similar to 1 to 250 mbar) in Titan's upper stratosphere. The light curves reveal a sharp inversion layer near 515 +/- 6 km altitude (1.5 mu bar pressure level), where the temperature increases by 15 K in only 6 km. This layer is close to an inversion layer observed fourteen months later by the Huygens HASI instrument during the entry of the probe in Titan's atmosphere on 14 January 2005 [ Fulchignoni et al., 2005]. Central flashes observed during the first occultation provide constraints on the zonal wind regime at 250 km, with a strong northern jet ( similar to 200 m s(-1)) around the latitude 55 degrees N, wind velocities of similar to 150 m s(-1) near the equator, and progressively weaker winds as more southern latitudes are probed. The haze distribution around Titan's limb at 250 km altitude is close to that predicted by the Global Circulation Model of Rannou et al. ( 2004) in the southern hemisphere, but a clearing north of 40 degrees N is necessary to explain our data. This contrasts with Rannou et al.' s ( 2004) model, which predicts a very thick polar hood over Titan's northern polar regions. Simultaneous observations of the flashes at various wavelengths provide a dependence of tau proportional to lambda(-q), with q = 1.8 +/- 0.5 between 0.51 and 2.2 mu m for the tangential optical depth of the hazes at 250 km altitude."

We performed an association study in 110 HIV-negative tuberculosis patients and 299 matched controls. In addition, a total of 155 healthy controls were screened for the tuberculin skin test (TST). DC-SIGN -336 SNP detection was performed by the real-time polymerase chain reaction technology, using the TaqMan 5' allele. The insertion/deletion in the ""neck"" region was analyzed by polymerase chain reaction with specific primers. Although an increased frequency of the G allele in tuberculosis patients (23176), as compared with controls (19%), was observed, differences were not statistically significant (OR = 1.31, 95176 CI = 0.89-1.94, P = 0.14). On the other hand, DC-SIGN repeat polymorphism in the ""neck"" region had a very low frequency in the analyzed population. We conclude that the studied polymorphisms are not relevant risk factors for developing tuberculosis in Northwestern Colombian individuals. Human Immunology 67, 808-811 (2006).

Ionization of large-scale absorbing haloes and feedback events from high-redshift radio galaxies	ASTRONOMY & ASTROPHYSICS		English	Article						cosmology : early universe; galaxies : active; galaxies : formation; galaxies : ISM; line : formation	LYMAN-ALPHA EMISSION; STAR-FORMATION; INTERGALACTIC MEDIUM; ABSORPTION-LINES; HII GALAXY; KINEMATICS; QUASARS; CLUSTER; SPECTROSCOPY; POPULATIONS	"Aims. We present photoionization calculations for the spatially-extended absorbers observed in front of the extended emission-line spectrum of two high-redshift radio galaxies, 0943 - 242 (z(e) = 2.922) and 0200 + 015 (z(e) = 2.230), with the aim of reproducing the absorber column ratio, N-CIV/N-HI. Methods. We explore the effects of using different UV continua in the photoionization calculations. A comparison is made between the absorber in 0200 + 015 and the two absorbers observed near the lensed Lynx arc nebula at redshift 3.36, which present very similar NCIV/NHI ratios. Results. We find that hot stars from a powerful starburst, or a metagalactic background radiation (MBR) in which stars dominate quasars, are equally successful in reproducing the observed NCIV/NHI, assuming subsolar gas metallicities for each absorber. These softer SEDs eliminate the difference of a factor 1000 in metallicity between the two absorbers encountered in earlier work where a power-law sed was assumed. The detection of continuum flux in 0943 - 242 suggests that the level of ionizing photons is consistent with a stellar ionizing source. Conclusions. If the MBR is responsible for the ionization of the radio galaxy absorbing shells, their radii (if spherical) would be large (> 100 kpc) and their mass huge > 10(12) M circle dot, implying that the feedback mechanism initiated by the central galaxy has caused the expulsion of more baryonic mass than that left in the radio galaxy. If, as we believe is more likely, stellar ionizing sources within the radio galaxy are responsible for the absorber's ionization, smaller radii of similar to 25 kpc and much smaller masses (similar to 10(8) - 10(10) M circle dot) are inferred. This radius is consistent with the observed transition in radio source size between the smaller sources in which strong Hi absorption is almost ubiquitous and the larger sources where it is mostly lacking. Finally, we outline further absorption-line diagnostics that could be used to further constrain the properties of the haloes and their source of ionization."

Our study population consisted of 130 serologically positive cardiomyopathic patients and 130 seropositive and asymptomatic individuals from a Colombian population where Trypanosoma cruzi infection is endemic. Genotyping of the ILIA (-889C/T, +4845G/T), IL1B (-511C/T, -31T/C, +3954T/C, +5810G/A) and IL1RN (+8006T/C, +8061C/T, + 1100T/C) polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism and polymerase chain reaction sequence-specific primer methods. Statistically significant differences in the distribution of the IL1B +5810 genotypes were observed comparing cardiomyopathic patients and asymptomatic individuals (p = 0.036). Frequency of the GG genotype was higher in the cardiomyopathic patient group than in the asymptomatic group (13% versus 5%, P = 0.03, odds ratio [OR] = 2.64, 95,76 confidence interval [CI] = 0.99-7-33). Differences in the distribution of the allele frequencies were also observed, being the +5810G allele overrepresented in patients with cardiomyopathy (37% versus 27%, p = 0.014, OR = 1.59, 95% Cl = 1.08-2.36). Examination of markers in the ILIA (-889 and +4845), IL1B (-511, -31, and +3954) and IL1RN (+11100) genes revealed that the overall distribution of alleles and genotypes in patients with chagasic cardiomyopathy and asymptomatic were not significantly different. Our results show that in,Colombian population the IL1B+5810G allele was associated with an increased risk chagasic cardiomyopathy. In addition, we demonstrated that homozygosity for the IL1B+5810G risk allele increased significantly the susceptibility to cardiomyopathy. This implies that the effect of IL1B gene on chagasic cardiomyopathy predisposition is dose dependent. We found that the haplotype CT of IL1B -31 and +3954 polymorphisms showed higher association with risk to chagasic cardiomyopathy (p(c) = 0.008, OR = 12.53) and the extended haplotype (CCT-CATT) was significantly more frequent in asymptomatic than in cardiomyopathic patients (p = 0.0014, P-c = 0.011, OR = 0.17). Therefore this study suggests that IL1 gene cluster polymorphisms may play a relevant role in the susceptibility to development of chagasic chronic cardiomyopathy.

Methods: A paired case control study ( 1: 1) was done based on records of the Epidemiological Surveillance System of Neural Tube Defects in Mexico; 151 cases of anencephaly of more than 20 weeks' gestation were selected between March 2000 and February 2001. Controls were selected from the same maternity services as those of the cases and were born alive without congenital malformations. Information was obtained from both parents by means of a general questionnaire, a food frequency questionnaire, and a specific questionnaire on occupational exposure to pesticides. Exposures were analysed with emphasis on the three months before and one month after the last menstruation periods ( acute risk period ( ARP)), as well as exposure prior to the abovementioned period ( non-acute risk period ( NARP)). Results: The children of mothers who worked in agriculture in the ARP had a greater risk of anencephaly ( OR = 4.57, 95% CI 1.05 to 19.96). The risk of fathers having a child with anencephaly was greater in those who applied pesticides irrespective of whether it was done in the ARP or the NARP ( OR = 2.50, 95% CI 0.73 to 8.64; and OR= 2.03, 95% CI 0.58 to 7.08, respectively). Conclusions: These results support the hypothesis of the effect of maternal exposure to agricultural work on anencephaly and suggest that exposure of the father to pesticides in the periconceptional period or prior to this can also increase the risk of having an anencephalic child."

A detailed spectroscopic study covering the blue to near-infrared wavelength range (.3700 angstrom-1 mu m) was performed for a sample of 34 HII galaxies in order to derive fundamental parameters for their HII regions and ionizing sources, as well as gaseous metal abundances. All the spectra included the nebular [SIII]lambda lambda 9069,9532 angstrom lines, given their importance in the derivation of the S/H abundance and relevant ionization diagnostics. Methods. A systematic method was followed to correct the near-IR [SIII] line fluxes for the effects of the atmospheric transmission. A comparative analysis of the predictions of the empirical abundance indicators R-23 and S-23 was performed for our sample galaxies. The relative hardness of their ionizing sources was studied using the. eta' parameter and exploring the role played by metallicity. Results. For 22 galaxies of the sample, a value of the electron temperature T-e[SIII] was derived, along with their ionic and total S/H abundances. Their ionic and total O/H abundances were derived using direct determinations of T-e[OIII]. For the rest of the objects, the total S/H abundance was derived using the S 23 calibration. The abundance range covered by our sample goes from 1/20 solar up to solar metallicity. Six galaxies present 12+log (O/H) <7.8 dex. The mean S/O ratio derived in this work is log (S/O) = -1.68 +/- 0.20 dex, 1 sigma below the solar (S/O)(circle dot) value. The S/O abundance ratio shows no significant trend with O/H over the range of abundance covered in this work, in agreement with previous findings. There is a trend for HII galaxies with lower gaseous metallicity to present harder ionizing spectra. We compared the distribution of the ionic ratios O+/O++ vs. S+/S++ derived for our sample with the predictions of a grid of photoionization models performed for three different stellar effective temperatures. This analysis indicates that a large fraction of galaxies in our sample seem to be ionized by extremely hard spectra, in line with recent suggestions for extra ionizing sources in HII galaxies."

Identification of the structural components and analysis of the internal kinematics in the planetary nebula IC 5217. Methods. Narrow- band images and high resolution long- slit spectra in the H alpha, [N II] and [O III] emission lines, and VLA 6 cm continuum data. Results. IC 5217 is composed of a very bright equatorial ring, open bipolar lobes, alpha- axis point- symmetric features, on- axis distant faint regions, and an off- axis very elongated bipolar structure. The ring, open lobes, point- symmetric features and distant faint regions appear as elements of a single point- symmetric bipolar shell with a very narrow waist. This shell presents an axis ratio of similar to 37 and an aspect ratio of similar to 5. The 6 cm data show that the ring is an extremely flat disk with a central hole. Expansion velocity in the ring ranges from <= 10 km s(-1) in He II up to similar or equal to 27 km s(-1) in [N II], whereas a velocity of similar to 460 km s(-1) is estimated for the polar regions of the bipolar shell. Strong acceleration of the outer regions of the ring is observed. The elongated bipolar structure probably represents a highly collimated (aspect ratio similar to 12), high velocity cylindrical- like shell. A collimated agent (wind or jet) would account for the shaping of the bipolar shell if this agent has operated in the direction perpendicular to the equatorial disk. The point- symmetric features and cylindrical shell are probably related to collimated ejections but that occurred when the basic nebular shape had already been established."

Characterization of zonal winds in the stratosphere of Titan with UVES: 2. Observations coordinated with the Huygens Probe entry	JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS		English	Article							TROPOSPHERIC CLOUDS; ATMOSPHERE; TEMPERATURES; OCCULTATION; DYNAMICS	"The Huygens Probe has successfully entered Titan's atmosphere and landed on its surface on 14 January 2005. With the aim of characterizing the zonal wind flow in Titan's stratosphere close to the time of entry, coordinated observations were carried out at the Very Large Telescope on the nights of 7, 12, 14, and 15 January. As in our previous investigation (Luz et al., 2005), we used the UVES instrument, mounted on the Kueyen-UT2 telescope, simultaneously achieving high spectral resolving power and high spatial resolution. The field has been derotated in order to align the 0.3-arcsec aperture perpendicularly to Titan's rotation axis. In this configuration, spatial information in the east-west direction is preserved in a set of spectra in the direction perpendicular to dispersion. We present measurements of zonal winds obtained with the technique of absolute accelerometry. The observations were made in the wavelength range 4200-6200 angstrom, probing between 115 and 280 km, with peak contributions at 200 and 170 km for the lower and upper parts of the domain. We detect prograde zonal winds with lower limits 46 and 53 ms(-1) at these altitudes. These values are close to our previous measurements."

Expression of a peroxisome proliferator-activated receptor gene (xPPAR alpha) from Xenopus laevis in tobacco (Nicotiana tabacum) plants	PLANTA		English	Article						acyl-CoA oxidase; clofibrate; Nicotiana tabacum; peroxisomes; peroxisome proliferator-activated receptor	FATTY-ACIDS; NITRIC-OXIDE; BETA-OXIDATION; TRANSGENIC TOBACCO; PPAR-GAMMA; DESATURASE; METABOLISM; MECHANISMS; YEAST; IDENTIFICATION	"In this work, we have genetically transformed tobacco (Nicotiana tabacum) plants with the peroxisome proliferator-activated receptor cDNA (xPPAR alpha) from Xenopus laevis, which is a transcriptional factor involved in the peroxisomal proliferation and induction of fatty acid beta-oxidation in animal cells. Several transgenic lines were generated and one representative line (T) from the R2 generation was selected for further studies. Analysis of free fatty acids revealed that unsaturated fatty acids such as C16:2 and C16:3 were deficient in line T, whereas saturated fatty acids like C16:0, C18:0, and C20:0 were more abundant than in non-transformed plants. Acyl-CoA oxidase (ACOX) activity was assayed as a marker enzyme of beta-oxidation in crude leaf extracts and it was found that in line T there was a threefold increase in enzyme activity. We also found that the peroxisome population was increased and that catalase (CAT) activity was induced by clofibrate, a known activator of xPPAR alpha protein, in leaves from line T. Taken together, these findings suggest that xPPAR alpha is functional in plants and that its expression in tobacco leads to changes in general lipid metabolism and peroxisomal proliferation as reported in animal cells. Furthermore, it indicates that there is an endogenous ligand in tobacco cells able to activate xPPAR alpha."

An optical supernova associated with the X-ray flash XRF 060218	NATURE		English	Article							LOW-LUMINOSITY; LIGHT-CURVE; BURST; AFTERGLOW; MODELS; GRB-030329; GRB-031203; DISCOVERY; SN-2006AJ; EMISSION	"Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae(1) that are more luminous than average(2-5) and that eject material at very high velocities. Less-luminous supernovae were not hitherto known to be associated with GRBs, and therefore GRB - supernovae were thought to be rare events(6). Whether X-ray flashes - analogues of GRBs, but with lower luminosities and fewer gamma-rays - can also be associated with supernovae, and whether they are intrinsically 'weak' events or typical GRBs viewed off the axis of the burst(7), is unclear. Here we report the optical discovery and follow-up observations of the type Ic supernova SN 2006aj associated with X-ray flash XRF 060218. Supernova 2006aj is intrinsically less luminous than the GRB - supernovae, but more luminous than many supernovae not accompanied by a GRB. The ejecta velocities derived from our spectra are intermediate between these two groups, which is consistent with the weakness of both the GRB output(8) and the supernova radio flux(9). Our data, combined with radio and X-ray observations(8-10), suggest that XRF 060218 is an intrinsically weak and soft event, rather than a classical GRB observed off-axis. This extends the GRB - supernova connection to X-ray flashes and fainter supernovae, implying a common origin. Events such as XRF 060218 are probably more numerous than GRB - supernovae."

Discovered in an infrared search at Kitt Peak 5 hr after the burst trigger, this afterglow is the faintest ever observed in the R band at such an early epoch and exhibits very red colors, with R - K approximate to 6. The optical magnitude of the afterglow of GRB 030115 is fainter than many upper limits for other bursts, suggesting that without early NIR observations it would have been classified as a ""dark'' burst. Both the color and optical magnitude of the afterglow are likely due to dust extinction at moderate redshift z > 2 and indicate that at least some optical afterglows are very faint due to dust along the line of sight. Multicolor Hubble Space Telescope observations were also taken of the host galaxy and the surrounding field. Photometric redshifts imply that the host and a substantial number of faint galaxies in the field are at z similar to 2.5. The overdensity of galaxies is sufficiently great that GRB 030115 may have occurred in a rich high-redshift cluster. The host galaxy shows extremely red colors (R - K = 5) and is the first GRB host to be classified as an extremely red object (ERO). Some of the galaxies surrounding the host also show very red colors, while the majority of the cluster are much bluer, indicating ongoing unobscured star formation. As it is thought that much of high-redshift star formation occurs in highly obscured environments, it may well be that GRB 030115 represents a transition object, between the relatively unobscured afterglows seen to date and a population of objects that are very heavily extinguished, even in the NIR."

Values in the nanomolar range were obtained for 50% effective dose against the Trypanosoma brucei subsp. rhodesiense bloodstream form cultured in vitro. In order to investigate the mode of action, Trypanosoma brucei subsp. brucei 24-SMT was cloned and overexpressed and compounds were assayed for inhibitory activity. None of the inhibitors tested appeared to be active against the enzyme. Sterol composition analysis showed that only cholestane type sterols are present in membranes of bloodstream forms while ergosterol is a major component of procyclic sterol extracts. Interestingly, Northern blot analysis showed the presence of 24-SMT mRNA in both the procyclic and the bloodstream forms of the parasite, although levels of mRNA were threefold lower in the latter. Likewise, Western blot analysis and activity determinations evidenced the existence of actives enzyme in both forms of the parasite. We conclude that the designed compounds act at sites other than 24-SMT in Trypanosoma brucei."

To investigate the physical nature of the afterglow emission. We report on the photometric, spectroscopic and polarimetric observations of the optical afterglow of Gamma-Ray Burst (GRB) 030328 detected by HETE-2. Methods. Photometric, spectroscopic and polarimetric monitoring of the optical afterglow. Results. Photometry, collected at 7 different telescopes, shows that a smoothly broken powerlaw decay, with indices alpha(1) = 0.76 +/- 0.03, alpha(2) = 1.50 +/- 0.07 and a break at t(b) = 0.48 +/- 0.03 days after the GRB, provides the best fit of the optical afterglow decline. This shape is interpreted as due to collimated emission, for which we determine a jet opening angle theta(jet) similar to 3 degrees.2. An achromatic bump starting around similar to 0.2 d after the GRB is possibly marginally detected in the optical light curves. Optical spectroscopy shows the presence of two rest-frame ultraviolet metal absorption systems at z = 1.5216 +/- 0.0006 and at z = 1.295 +/- 0.001, the former likely associated with the GRB host galaxy. Analysis of the absorption lines at z = 1.5216 suggests that the host of this GRB may be a Damped Lyman-alpha Absorber. The optical V-band afterglow appears polarized, with P = (2.4 +/- 0.6)% and theta = 170 degrees +/- 7 degrees, suggesting an asymmetric blastwave expansion. An X-ray-to-optical spectral flux distribution of the GRB 030328 afterglow was obtained at 0.78 days after the GRB and fitted using a broken powerlaw, with an optical spectral slope beta(opt) = 0.47 +/- 0.15, and an X-ray slope beta(X) = 1.0 +/- 0.2. Conclusions. The discussion of the results in the context of the ""fireball model"" shows that the preferred scenario for this afterglow is collimated structured jet with fixed opening angle in a homogeneous medium."

We report the molecular characterization of the genes encoding histone H2A protein from a T rangeli KP1(+) strain (H14), its comparison to T rangeli KPI(-) strain (C23) histone H2A coding genes [Puerta, C., Cuervo, P., Thomas, M.C., Lopez, M.C., 2000. Molecular characterization of the histone H2A gene from the parasite Trypanosoma rangeli. Parasitol. Res. 86, 916--922], and its application in a low-stringency single specific primer polymerase chain reaction (LSSP-PCR) assay to differentiate these parasite groups. The results show that the locus encoding the H2A protein in the H14 strain is formed by at least 11 gene units measuring 799 nucleotides in length, organized in tandem, and located in two chromosomes of approximately 1.9 and 1.1 Mb in size. Remarkably, in KPI(-) strains these genes are on pairs of chromosomes of about 1.7 and 1.9 Mb. In addition, there is a hybridization signal in the compression region above 2.1 Mb in all T. rangeli strains. Therefore, the chromosomal location of these genes is a useful marker to distinguish between KPI(+) and KPI(-) T. rangeli strains. The alignment of the H2A nucleotide sequences from H14 and C23 strains showed an identity of 99.5% between the coding regions and an identity of 95% between the non-coding regions. The deduced amino acid sequences proved to be identical. Based on 5% of the difference between the intergenic regions, we developed a LSSP-PCR assay which can differentiate between KPI(+) and KPI(-) strains. (c) 2006 Elsevier B.V. All rights reserved."

Our study includes 711 systemic lupus erythematosus (SLE) patients and 755 healthy controls. We genotyped the migration inhibitory factor (MIF) -173G/C using a polymerase chain reaction (PCR) system with predeveloped TaqMan allelic discrimination assay and the MIF -794 CATT(n) microsatellite polymorphism using a PCR-fluorescent method. A statistically significant difference in the distribution of the MIF -173*C allele between SLE patients and controls (P = 0.004, OR 1.34, 95% CI 1.05-1.27) was observed. In addition, the frequency of the MIF -173*C/C genotype was higher in SLE patient (P = 0.002, OR 2.58, 95% CI 1.32-5.10). No differences in the distribution of CATTn were found. However, the haplotypes analyses showed that only the CATT(7)-MIF-173*C haplotype was associated with a higher susceptibility to SLE (P = 0.001, OR 1.84, 95% CI 1.35-2.79). No association with clinical features was detected in any case. These results suggest that both, MIF -173*C allele and CATT(7)-MIF-173*C haplotype, confer susceptibility to SLE in our population."

We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Flash (XRF). XRF 060218 is clearly associated with a supernova-dubbed SN2006aj. Methods. We present early spectra for SN2006aj as well as optical lightcurves reaching out to 50 days past explosion. Results. Our optical lightcurves define the rise times, the lightcurve shapes and the absolute magnitudes in the U, V and R bands, and we compare these data with data for other relevant supernovae. SN2006aj evolved quite fast, somewhat similarly to SN2002ap, but not as fast as SN1994I. Our spectra show the evolution of the supernova over the peak, when the U-band portion of the spectrum rapidly fades due to extensive line blanketing. We compare to similar spectra of very energetic type Ic supernovae. Our first spectra are earlier than spectra for any other GRB-SN. The spectrum taken 12 days after burst in the rest frame is similar to somewhat later spectra of both SN1998bw and SN2003dh, implying a rapid early evolution. This is consistent with the fast lightcurve. From the narrow emission lines from the host galaxy we derive a redshift of z = 0.0331 +/- 0.0007. This makes XRF 060218 the second closest gamma-ray burst detected. The flux of these emission lines indicate a high-excitation state, and a modest metallicity and star formation rate of the host galaxy."

The detection of magnetic chemically peculiar (CP2) stars in open clusters of the Milky Way can be used to study the influence of different galactic environments on the (non-)presence of peculiarities, which has to be taken into account in stellar evolution models. Furthermore it is still unknown if the CP2 phenomenon evolves, i.e. does the strength of the peculiarity feature at 5200 angstrom increase or decrease with age. Methods. We have observed eight young to intermediate age open clusters in the. a photometric system. This intermediate band photometric system samples the depth of the 5200 angstrom flux depression by comparing the flux at the center with the adjacent regions having bandwidths of 110 angstrom to 230 angstrom. The Delta a photometric system is most suitable to detect CP2 stars with high efficiency, but is also capable of detecting a small percentage of non-magnetic CP objects. Also, the groups of (metal-weak). Bootis, as well as classical Be/shell stars, can be successfully investigated. This photometric system allows one to determine the age, reddening and distance modulus by fitting isochrones. Results. Among the presented sample of eight galactic clusters, we have detected twenty three CP2, eight Be/Ae and eight metal-weak stars. Another six objects show a peculiar behaviour which is most probably due to a non-membership, variability or duplicity. Fitting isochrones to a photometry yields estimates of the age, reddening and distance that are in excellent agreement with published values."

Kinematically perturbed gas, which we have shown to be within the radio structure in previous publications, is always blueshifted with respect to the kinematically quiescent gas, is usually spatially extended, and is usually detected on both sides of the nucleus. In the three objects from this sample for which we are able to measure line ratios for both the perturbed and quiescent gases, we suggest that the former has a lower ionization state than the latter. We propose that the perturbed gas is part of a jet-induced outflow, with dust obscuring the outflowing gas that lies on the far side of the object. The spatial extent of the blueshifted perturbed gas, typically similar to 35 kpc, implies that the dust is spatially extended at least on similar spatial scales. We also find interesting interrelationships between UV line, UV continuum and radio continuum properties of this sample."

Out of the 10 strains, the five slow-growing isolates grew well under oxygen-limiting conditions with nitrate as a sole nitrogen source, and accumulated nitrous oxide in the growth medium when acetylene was used to inhibit nitrous oxide reductase activity. All five strains contained DNA homologous to the Bradyrhizobium japonicum nirK, norBDQ and nosZ genes. In contrast, fast-growing lotus rhizobia were incapable of growing under nitrate-respiring conditions, and did not accumulate nitrous oxide in the growth medium. DNA from each of the five fast-growing strains showed a hybridization band with the B. japonicum nirK gene but not with norBDQ and nosZ genes. Partial 16S rDNA gene sequencing revealed that fast-growing strains could be identified as Mesorhizobium loti species and the slow-growers as Bradyrhizobium sp."

Because Lyp is an important molecule involved in the inflammatory response, and its levels are increased in cells that participate in the immune response against Mycobacterium tuberculosis, we hypothesized that the functional PTPN22 C1858T polymorphism could be a genetic factor predisposing to the development of tuberculosis (TB). Accordingly, we undertook an association study in which 113 patients with pulmonary TB and 161 matched healthy controls stratified by the tuberculin skin test (TST) were examined. Significant skewing was observed when T allele frequencies of patients with TB and all controls were compared (P = 0.04, odds ratio = 0.3; 95% confidence interval = 0.08-1.04) and frequencies of patients with TB and TST+ healthy controls were compared (P = 0.01, odds ratio = 0.2; 95% confidence interval = 0.05-0.79). No stratification was detected between patients and control samples. These results suggest that the T allele may be a factor protecting against development of TB once the immune system recognizes M. tuberculosis (i.e., TST+ individuals), whereas the C allele may be a risk factor for development of overt TB. The results also indicate that an association opposite that between the PTPN22 polymorphism and TB exists between TB and autoimmunity."

These images provide the most photometrically accurate and morphologically detailed views of the disk between 30 and 300 AU from the star ever recorded in scattered light. We confirm that the previously reported warp in the inner disk is a distinct secondary disk inclined by similar to 5 degrees from the main disk. The projected spine of the secondary disk coincides with the isophotal inflections, or ""butterfly asymmetry,'' previously seen at large distances from the star. We also confirm that the opposing extensions of the main disk have different position angles, but we find that this ""wing-tilt asymmetry'' is centered on the star rather than offset from it, as previously reported. The main disk's northeast extension is linear from 80 to 250 AU, but the southwest extension is distinctly bowed with an amplitude of similar to 1 AU over the same region. Both extensions of the secondary disk appear linear, but not collinear, from 80 to 150 AU. Within similar to 120 AU of the star, the main disk is similar to 50% thinner than previously reported. The surface brightness profiles along the spine of the main disk are fitted with four distinct radial power laws between 40 and 250 AU, while those of the secondary disk between 80 and 150 AU are fitted with single power laws. These discrepancies suggest that the two disks have different grain compositions or size distributions. The F606W/F435W and F814W/F435W flux ratios of the composite disk are nonuniform and asymmetric about both projected axes of the disk. The disk's northwest region appears 20%-30% redder than its southeast region, which is inconsistent with the notion that forward scattering from the nearer northwest side of the disk should diminish with increasing wavelength. Within similar to 120 AU, the m(F435W)-m(F606W) and m(F435W)-m(F814W) colors along the spine of the main disk are similar to 10% and similar to 20% redder, respectively, than those of beta Pic. These colors increasingly redden beyond similar to 120 AU, becoming 25% and 40% redder, respectively, than the star at 250 AU. These measurements overrule previous determinations that the disk is composed of neutrally scattering grains. The change in color gradient at similar to 120 AU nearly coincides with the prominent inflection in the surface brightness profile at similar to 115 AU and the expected water-ice sublimation boundary. We compare the observed red colors within similar to 120 AU with the simulated colors of nonicy grains having a radial number density alpha r(-3) and different compositions, porosities, and minimum grain sizes. The observed colors are consistent with those of compact or moderately porous grains of astronomical silicate and/or graphite with sizes greater than or similar to 0.15-0.20 mu m, but the colors are inconsistent with the blue colors expected from grains with porosities greater than or similar to 90%. The increasingly red colors beyond the ice sublimation zone may indicate the condensation of icy mantles on the refractory grains, or they may reflect an increasing minimum grain size caused by the cessation of cometary activity."

Whether it is beneficial to administer prone ventilation early, and for longer periods of time, is unknown. Methods: We enrolled 136 patients within 48 h of tracheal intubation for severe ARDS, 60 randomized to supine and 76 to prone ventilation. Guidelines were established for ventilator settings and weaning. The prone group was targeted to receive continuous prone ventilation treatment for 20 h/d. Results: The intensive care unit mortality was 58% (35/60) in the patients ventilated supine and 43% (33/76) in the patients ventilated prone (p = 0.12). The latter had a higher simplified acute physiology score II at inclusion. Multivariate analysis showed that simplified acute physiology score II at inclusion (odds ratio [OR], 1.07; p < 0.001), number of days elapsed between ARDS diagnosis and inclusion (OR, 2.83; p < 0.001), and randomization to supine position (OR, 2.53; p = 0.03) were independent risk factors for mortality. A total of 718 turning procedures were done, and prone position was applied for a mean of 17 h/d for a mean of 10 d. A total of 28 complications were reported, and most were rapidly reversible. Conclusion: Prone ventilation is feasible and safe, and may reduce mortality in patients with severe ARDS when it is initiated early and applied for most of the day."

Co-inoculation (Gluconacetobacter diazotrophicus plus Gloinus mosseae) did not increase the shoot and root dry weight of either plant. There was a synergistic effect of Gluconacetobacter diazotrophicus on root colonization of maize by Glomus intraradices, whereas an antagonistic interaction was observed in the sorghum root where the number of Gluconacetobacter diazotrophicus and the colonization by Glomus intraradices were reduced. Plant roots inoculated with Glucottacetobacter diazotrophicus and Glomus intraradices, either separately or together, significantly increased root endoglucanase, endopolymethylgalacturonase and endoxyloglucanase activities. The increase varied according to the plant. For example, in comparison with non-inoculated plants, there were higher endoglucanase (+328%), endopolymethylgalacturonase (+ 180%) and endoxyloglucanase (+ 125%) activities in 45-day old co-inoculated maize, but not in 45-day old sorghum.

Long gamma-ray bursts and core-collapse supernovae have different environments	NATURE		English	Article							HOST GALAXIES; LOW METALLICITY; MASSIVE STARS; IA SUPERNOVAE; REDSHIFT; AFTERGLOW; PROGENITORS; RATES; SPECTROSCOPY; CONSTRAINTS	"When massive stars exhaust their fuel, they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse also powers an even more brilliant relativistic explosion known as a long-duration gamma-ray burst. One would then expect that these long gamma-ray bursts and core-collapse supernovae should be found in similar galactic environments. Here we show that this expectation is wrong. We find that the gamma-ray bursts are far more concentrated in the very brightest regions of their host galaxies than are the core-collapse supernovae. Furthermore, the host galaxies of the long gamma-ray bursts are significantly fainter and more irregular than the hosts of the core-collapse supernovae. Together these results suggest that long-duration gamma-ray bursts are associated with the most extremely massive stars and may be restricted to galaxies of limited chemical evolution. Our results directly imply that long gamma-ray bursts are relatively rare in galaxies such as our own Milky Way."

The model assumes a massive and young stellar cluster surrounded by a large collection of clouds. These are thus exposed to the most important star formation feedback mechanisms: photoionization and the cluster wind. The models show how he two feedback mechanisms compete with each other in the disruption of clouds and lead to two different hydrodynamic solutions: the storage of clouds into a long-lasting ragged shell that inhibits the expansion of the thermalized wind and the steady filtering of the shocked wind gas through channels carved within the cloud stratum. Both solutions are here claimed to be concurrently at work in giant H (II) regions and H (II) galaxies, causing their detailed inner structure. This includes multiple large-scale shells, filled with an X-ray-emitting gas, that evolve to finally merge with each other, giving the appearance of shells within shells. The models also show how the inner filamentary structure of the giant superbubbles is largely enhanced with matter ablated from clouds and how cloud ablation proceeds within the original cloud stratum. The calculations point at the initial contrast density between the cloud and the intercloud media as the factor that defines which of the two feedback mechanisms becomes dominant throughout the evolution.

The afterglow showed a very rapid rise in the first day, followed by a relatively slow decay in the next few days. There was a clear bump in the light curve after similar to 25 days, accompanied by a drastic change in the spectral energy distribution. The light curve and the spectral energy distribution are naturally interpreted as describing the emergence and subsequent decay of a supernova ( SN), similar to SN 1998bw. At peak luminosity, the SN is estimated to be 0.8 +/- 0.1 mag fainter than SN 1998bw. This argues in favor of the existence of a SN associated with this XRF. A spectrum obtained 35 days after the burst shows emission lines from the host galaxy. We use this spectrum to put an upper limit on the oxygen abundance of the host at [O/H] <= 0.6 dex. We also discuss a possible trend between the softness of several bursts and the early behavior of the optical afterglow, in the sense that XRFs and X-ray-rich gamma-ray bursts ( GRBs) seem to have a plateau phase or even a rising light curve. This can be naturally explained in models in which XRFs are similar to GRBs but are seen off the jet axis."

Objective: To test the possible role of these variants in susceptibility to or severity of systemic lupus erythematosus (SLE), on the basis that common genetic bases are shared by autoimmune disorders. Methods: 597 SLE patients and 987 healthy controls of white Spanish origin were studied. Two additional cohorts of 228 SLE patients from Sweden and 122 SLE patients from Colombia were included. A case control association study was carried out with six single nucleotide polymorphisms (SNP) spanning the SLC22A4 gene, one SNP in RUNX1 gene, and one additional SNP in SUM04 gene. Results: No significant differences were observed between SLE patients and healthy controls when comparing the distribution of the genotypes or alleles of any of the SLC22A4, RUNX1, or SUMO4 polymorphisms tested. Significant differences were found in the distribution of the SUMO4 genotypes and alleles among SLE patients with and without nephritis, but after multiple testing correction, the significance of the association was lost. The association of SUMO4 with nephritis could not be verified in two independent SLE cohorts from Sweden and Colombia. Conclusions: These results suggest that the SLC22A4, RUNX1, and SUMO4 polymorphisms analysed do not play a role in the susceptibility to or severity of SLE."

We present early optical spectroscopy of the afterglow of the gamma-ray burst GRB060206 with the aim of determining the metallicity of the GRB absorber and the physical conditions in the circumburst medium. We also discuss how GRBs may be important complementary probes of cosmic chemical evolution. Methods. Absorption line study of the GRB afterglow spectrum. Results. We determine the redshift of the GRB to be z = 4.04795 +/- 0.00020. Based on the measurement of the neutral hydrogen column density from the damped Lyman-alpha line and the metal content from weak, unsaturated S II lines we derive a metallicity of [S/H] = -0.84 +/- 0.10. This is one of the highest metallicities measured from absorption lines at z similar to 4. From the very high column densities for the forbidden Si II*, O I*, and O I** lines we infer very high densities and low temperatures in the system. There is evidence for the presence of H-2 molecules with log N(H-2) similar to 17.0, translating into a molecular fraction of log f approximate to 3.5 with f = 2N(H-2)/(2N(H-2) + N(H-I)). Even if GRBs are only formed by single massive stars with metallicities below similar to 0.3 Z(circle dot), they could still be fairly unbiased tracers of the bulk of the star formation at z > 2. Hence, metallicities as derived for GRB060206 here for a complete sample of GRB afterglows will directly show the distribution of metallicities for representative star-forming galaxies at these redshifts."

The rs2004640 T allele creates a 5' donor splice site in an alternate exon 1 of IRF5, allowing expression of several unique IRF5 isoforms. We also identify an independent cis-acting variant associated with elevated expression of IRF5 and linked to the exon 1B splice site. Haplotypes carrying the variant associated with elevated expression and lacking the exon 1B donor site do not confer risk of SLE.

Out of the 40 star-forming regions surveyed in the CCS (2(1) - 1(0)) line, only six low- mass sources show CCS emission: one transitional object between the prestellar and protostellar Class 0 phase (GF9-2), three Class 0 protostars (L1448-IRS3, L1448C, and B1-IRS), a Class I source (L1251A), and a young T Tauri star (NGC 2071 North). Since CCS is considered an ""early-time'' (less than or similar to 10(5) yr) molecule, we explain these results by either proposing a revision of the classification of the age of NGC 2071 North and L1251A, or suggesting the possibility that the particular physical conditions and processes of each source affect the destruction/production of the CCS. No statistically significant relationship was found between the presence of CCS and parameters of the molecular outflows and their driving sources. Nevertheless, we found a significant relationship between the detectability of CCS and the ammonia peak intensity ( higher in regions with CCS), but not with its integrated intensity. This tendency may suggest that the narrower ammonia line widths in the less turbulent medium associated with younger cores may compensate for the differences in ammonia peak intensity, rendering differences in integrated intensity negligible. From the CCS detection rate we derive a lifetime of this molecule of similar or equal to(0.7-3) x 10(4) yr in low-mass star-forming regions."

The aim of this work is to identify and study spectral features in the quasar 3C 273 usually blended by its strong jet emission. Methods.

The overall spectrum is used to model the infrared and X- ray spectral components. Results. Three thermal dust emission components are identified in the infrared. The dust emission on scales from 1 pc to several kpc is comparable to that of other quasars, as expected by AGN unification schemes. The observed weakness of the X-ray emission supports the hypothesis of a synchrotron self-Compton origin for the jet component. There is a clear soft-excess and we find evidence for a very broad iron line which could be emitted in a disk around a Kerr black hole.

The previous assessment of a care center, including patients or residents and staff, allows an effective strategy to be designed. Oral health protocols are mainly based on the daily removal of bacterial plaque from teeth or prostheses (or both), cleaning of oral mucosa, and continual oral hydration. These practices are facilitated by the use of electric toothbrushes and products such as chlorhexidine, fluoride toothpastes, and rinses or gels for dry mouth. This type of protocol should include regular collaboration with dental professionals and provide a program of continuous training for nursing staff on oral health issues."

We first generate fractal clouds with a given fractal dimension and associate each clump with a maximum in the resulting density field. Then, we discuss the effect that different criteria for clump selection have on the derived global properties. We calculate the masses, sizes, and average densities of the clumps as a function of the fractal dimension (D-f) and the fraction of the total mass in the form of clumps (epsilon). In general, clump mass does not fulfill a simple power law with size of the type M-cl proportional to R-cl(gamma); instead, the power changes, from gamma similar or equal to 3 at small sizes to gamma < 3 at larger sizes. The number of clumps per logarithmic mass interval can be fitted to a power law N-cl proportional to M-cl(-alpha M) cl in the range of relatively large masses, and the corresponding size distribution is N-cl proportional to M-cl(-alpha M) cl at large sizes. When all the mass is forming clumps (epsilon = 1), we obtain that as Df increases from 2 to 3, alpha(M) increases from similar to 0.3 to similar to 0.6 and alpha(R) increases from similar to 1.0 to similar to 2.1. Comparison with observations suggests that D-f similar or equal to 2: 6 is roughly consistent with the average properties of the ISM. On the other hand, as the fraction of mass in clumps decreases (epsilon < 1), alpha(M) increases and alpha(R) decreases. When only similar to 10% of the complex mass is in the form of dense clumps, we obtain alpha(M) similar or equal to 1.2 for D-f = 2.6 ( not very different from the Salpeter value 1.35), suggesting this a likely link between the stellar initial mass function and the internal structure of molecular cloud complexes."

A few H-beta-Crawford measurements were also collected for calibration purposes and they locate this star well inside the gamma Dor instability region. We find HD 218427 to be deficient in metals, similar to other well-defined gamma Dor stars, and discuss the possibility that it has a lambda Boo nature. We carried out frequency analysis for different filters, including the combined ""vby"" filter, and five frequencies were found as significant with periods ranging between 0.3 and 0.8 days. The recently-developed frequency ratio method is used in order to identify the excited modes. The results are consistent with an l = 2 identification for all the modes and with high radial quantum numbers ( n similar to 40) for the three main observed periodicities. The possibility of multiplet structures is also discussed. However, no consistency is found when using the time-dependent convection treatment to discriminate modes. This disagreement can be due to the large rotation velocity taking place in HD218427 and, consequently, the significant coupling between the modes."

Although these statistics has been formulated using crisp mathematics, their use returns statements about ""quality control"" which are full of vagueness (for example, the aforementioned idea of precise or imprecise processes). For this reason, it seems both natural and interesting to introduce tools from Fuzzy Sets Theory for the formulation of quality control models. Fuzzy Sets shall be used to study process quality capability and to generate a bilateral simultaneous control for the central tendency and a unilateral one for variability.

The surface density of these z similar to 5: 8 candidates is approximately 6 times higher than the number expected from deep ACS fields. This is one of the highest galaxy overdensities at high redshifts, which may develop into a group or cluster. We also find evidence for a substructure associated with one of the candidates. It has two very faint companion objects within 200, which are likely to merge. The finding supports the results of a recent simulation, which finds that luminous quasars at high redshifts lie on the most prominent dark matter filaments and are surrounded by many fainter galaxies.

The results indicate that the hydrolytic activity of the PA15 strain was inducible, whereas that of the UAP5541 strain seems to be constitutive (regardless of the concentration of sucrose used). When the concentration of the enzymatic substrates was increased in the culture medium, the production of hydrolytic enzymes decreased. The different behaviour of the strains PA15 and UAP5541 grown in the culture medium with different concentrations of sucrose and the enzymatic substrates demonstrates, that the microbial response and the control of the enzymatic expression of G. diazotrophicus strains were different and complex and may be important in their capacity to penetrate plant root as well as in their competitive capacity against other microorganisms."

Contrary to the case for the widely used O-23 parameter, the calibration remains single valued up to the abundance values observed in the disk HII regions. The calibration is based on a large sample of nebulae for which direct determinations of electron temperatures exist and the sulphur chemical abundances can be directly derived. ICFs, as derived from the [SIV] 10.52 mu emission line (ISO observations), are shown to be well reproduced by Barker's formula for a value of alpha = 2.5. Only about 30% of the objects in the sample require ICFs larger than 1.2.

Comparison with the predictions of linear non-adiabatic radial pulsation models allowed us to identify only five of the nine observed frequencies, and to constrain the position of IP Per in the HR diagram. The latter is in good agreement with the empirical determination of the stellar parameters obtained by Miroshnichenko et al. ( 2001, A&A, 377, 854). An initial interpretation of the observed frequencies using the Aarhus non-radial pulsation code suggests that three frequencies could be associated with non-radial ( l = 2) modes. Finally, we present new evolutionary and pulsation models at lower metallicity ( Z = 0.008) to take into account the possibility that IP Per is metal deficient, as indicated by Miroshnichenko et al.

Both the bursts themselves and their afterglows have been predicted to be visible out to redshifts of z approximate to 20, and therefore to be powerful probes of the early Universe(1,2). The burst GRB 000131, at z = 4.50, was hitherto the most distant such event identified(3). Here we report the discovery of the bright near-infrared afterglow of GRB 050904 (ref. 4). From our measurements of the near-infrared afterglow, and our failure to detect the optical afterglow, we determine the photometric redshift of the burst to be z = 6.39(-0.12)(+0.11) (refs 5-7). Subsequently, it was measured(8) spectroscopically to be z = 6.29 +/- 0.01, in agreement with our photometric estimate. These results demonstrate that GRBs can be used to trace the star formation, metallicity, and reionization histories of the early Universe."

Cluster members were selected from the Hubble Space Telescope Advanced Camera for Surveys (HST ACS) images, combined with ground-based near-IR imaging and optical spectroscopy. The observed early-type color-magnitude relation (CMR) in i(775) - z(850) versus z(850) shows an intrinsic scatter in color of 0.060 +/- 0.009 mag, within 10 from the cluster X-ray emission center. Both the elliptical and the S0 galaxies show small scatter about the CMR of 0.042 +/- 0.010 and 0.044 +/- 0.020 mag, respectively. From the scatter about the CMR, a mean luminosity weighted age t > 3: 3 Gyr (z(f) approximate to 3) is derived for the elliptical galaxies, assuming a simple stellar population modeling (single-burst solar metallicity). Strikingly, the S0 galaxies in RDCS J0910+5422 are systematically bluer in i(775) - z(850), by 0.07 +/- 0.02 mag, than the ellipticals. The ellipticity distribution as a function of color indicates that the face-on S0s in this particular cluster have likely been classified as elliptical. Thus, if anything, the offset in color between the elliptical and S0 populations may be even more significant. The color offset between S0 and E galaxies corresponds to an age difference of approximate to 1 Gyr for a single-burst solar-metallicity model. A solar-metallicity model with an exponential decay in star formation will reproduce the offset for an age of 3.5 Gyr; i.e., the S0s have evolved gradually from star-forming progenitors. The early-type population in this cluster appears to be still forming. The blue early-type disk galaxies in RDCS J0910+5422 likely represent the direct progenitors of the more evolved S0s that follow the same red sequence as elliptical galaxies in other clusters. Thirteen red galaxy pairs are observed, and the galaxies associated in pairs constitute similar to 40% of the CMR galaxies in this cluster."

We obtain accurate radial velocities for 42 globular clusters (GCs) in total, 30 for GCs around the elliptical NGC 3379, eight around the lenticular NGC 3384, and four which may be associated with either galaxy. These data are notable for their large radial range extending from 0.'7 to 14.'5 (2 to 42 kpc) from the centre of NGC 3379, and small velocity uncertainties of about 10 km s(-1). We combine our sample of 30 radial velocities for globular clusters around NGC 3379 with 8 additional GC velocities from the literature, and find a projected velocity dispersion of sigma(p) = 175(-22)(+24) km s(-1) at R < 5' and sigma(p) = 147(-39)(+44) at R > 5'. These velocity dispersions are consistent with a dark matter halo around NGC 3379 with a concentration in the range expected from a Lambda CDM cosmological model and a total mass of approximate to 6 x 10(11) M-.. Such a model is also consistent with the stellar velocity dispersion at small radii and the rotation of the H I ring at large radii, and has a (M/L)(B) that increases by a factor of five from several kpc to 100 kpc. Our velocity dispersion for the globular cluster system of NGC 3379 is somewhat higher than that found for the planetary nebulae (PNe) in the inner region covered by the PN data, and we discuss possible reasons for this difference. For NGC 3384, we find the GC system has a rotation signature broadly similar to that seen in other kinematic probes of this SB0 galaxy. This suggests that significant rotation may not be unusual in the GC systems of disc galaxies."

This radio galaxy has six spectroscopically confirmed Ly alpha-emitting companion galaxies and appears to lie within an overdense region. The radio galaxy is marginally resolved in i(775) and z(850), showing continuum emission aligned with the radio axis, similar to what is observed for lower redshift radio galaxies. Both the half-light radius and the UV star formation rate are comparable to the typical values found for Lyman break galaxies at z similar to 4-5. The Ly alpha emitters are sub-L-* galaxies, with deduced star formation rates of 1-10 M-circle dot yr(-1). One of the Ly alpha emitters is only detected in Ly alpha. Based on the star formation rate of similar to 3 M-circle dot yr(-1) calculated from Ly alpha, the lack of continuum emission could be explained if the galaxy is younger than similar to 2 Myr and is producing its first stars. Observations in V(606)i(775)z(850) were used to identify additional Lyman break galaxies associated with this structure. In addition to the radio galaxy, there are 22 V-606 break (z similar to 5) galaxies with z(850) < 26.5 (5 sigma), two of which are also in the spectroscopic sample. We compare the surface density of similar to 2 arcmin(-2) to that of similarly selected V-606 dropouts extracted from GOODS and the UDF parallel fields. We find evidence for an overdensity to very high confidence (> 99%), based on a counts-in-cells analysis applied to the control field. The excess suggests that the V-606 break objects are associated with a forming cluster around the radio galaxy."

The K1 peptide derived from T. cruzi KMP-11 protein has a high binding affinity to the HLA-A*0201 molecule. Nevertheless, it is not known whether this peptide is processed and displayed as an MHC class I epitope during natural infection by T. cruzi. The aim of this study was to evaluate, by ELISPOT assay, the ability of K1 peptide to activate CD8(+)T lymphocytes to produce IFN-gamma. Therefore, CD8(+)T lymphocytes from 22 HLA-A*0201(+)individuals, 12 chronic chagasic patients and 10 uninfected controls, were analysed. The results revealed that two of the chagasic patients had IFN-gamma-secreting CD8(+)T cells that were able to respond to K1 peptide with a relative frequency of 110 and 230 per million CD8(+)T cells. In contrast, none of HLA-A*0201(+)uninfected controls responded to K1 peptide. Responses to HLA-A*0201 restricted peptide from the influenza matrix protein were found in six chagasic patients and four uninfected controls with an average frequency of 175 and 111 cells per million CD8(+)T cells, respectively. Moreover, a flow cytometric assay for degranulation showed that chagasic responders had K1-specific cytotoxic CD8(+) T cells. It is shown here for the first time that the K1 peptide is efficiently processed, presented and recognized by CD8(+)T lymphocytes during the natural course of Chagas disease."

Our spectrum of GRB 991216 is the only optical spectrum for this afterglow. It shows two probable absorption systems at z = 0.80 and z = 1.02, where the highest redshift most likely reflects the distance to the host galaxy. A third system may be detected at z = 0.77. HST imaging of the field, obtained 4 months after the burst, has resulted in the detection of two amorphous regions of emission, one at the projected afterglow position, and the other 0.''6 away. The spectrum shows a depression in flux in between 4000 angstrom and 5500 angstrom. This could be the result of a 2175 angstrom-type extinction feature in the host of GRB 991216, but at a rather red wavelength of 2360 angstrom. If this interpretation is correct, it is the first time the extinction feature is seen in a GRB afterglow spectrum. It is centered at a wavelength similar to that of the ultra-violet (UV) bumps inferred from observations of a few UV-strong, hydrogen-poor stars in the Galaxy. All significant absorption lines (except for one) detected in the spectrum of GRB 011211 are identified with lines originating in a single absorption system at z = 2.142 +/- 0.002, the redshift of the GRB 011211 host galaxy. We also detect the Ly alpha absorption line in the host, to which we fit a neutral hydrogen column density of log N( H I) = 20.4 +/- 0.2, which indicates that it is a damped Lya system. Using a curve-of-growth analysis, we estimate the Si, Fe and Al metallicity at the GRB 011211 redshift to be [Si/H] = -0.9(-0.4)(+0.6), [Fe/H] = -1.3 +/- 0.3, and [Al/H] = -1.0(-0.3)(+0.5) . For GRB 021211, we detect a single emission line in a spectrum obtained tens of days after the burst, which we identify as [O II] lambda 3727 at z = 1.006. The corresponding unobscured [O II] star-formation rate is 1.4 M-circle dot yr(-1)."

Our frequency analysis results in the detection of 23 sinusoidal signals in the light curves. Ten of those correspond to independent pulsation modes, and the remainder are combination frequencies. We find some slow aperiodic variability such as that seemingly present in several beta Cephei stars. We perform mode identification from our colour photometry, derive the spherical degree l for the five strongest modes unambiguously and provide constraints on l for the weaker modes. We find a mixture of modes of 0 <= l <= 4. In particular, we prove that the previously suspected rotationally split triplet within the modes of 12 Lac consists of modes of different l; their equal frequency splitting must thus be accidental. One of the periodic signals we detected in the light curves is argued to be a linearly stable mode excited to visible amplitude by non-linear mode coupling via a 2:1 resonance. We also find a low-frequency signal in the light variations whose physical nature is unclear; it could be a parent or daughter mode resonantly coupled. The remaining combination frequencies are consistent with simple light-curve distortions. The range of excited pulsation frequencies of 12 Lac may be sufficiently large that it cannot be reproduced by standard models. We suspect that the star has a larger metal abundance in the pulsational driving zone, a hypothesis also capable of explaining the presence of beta Cephei stars in the Large Magellanic Cloud."

Different techniques, tested with simulated time series, are used to calculate this parameter, so that the results are reliable. We find that there is strong correlation in the region, and that small earthquakes are very important to the stress transfers. In addition, it is shown that predictability in an earthquake system is a function of the relationship between magnitude and energy, and that seismicity rate, or number of events, provides the best measure of this predictability."

We morphologically segregate galaxies using a combination of visual classification and objective machine-based selection. We use the asymmetry (A) and central concentration (C) parameters to characterize galaxies up to z(850,AB) < 25 mag. We take advantage of the multicolor data set and estimate redshifts for our sample using the Bayesian photometric redshift, which enables us to investigate the evolution of their morphological demographics with redshift. Using a template fitting model and a maximum likelihood approach, we compute the star formation rate (SFR) for galaxies up to z similar or equal to 1.3 and its contributions from different morphological types. We report that spiral galaxies are the main providers to the total SFR. The E/S0 contribution flattens out at z similar or equal to 1, while the irregular/peculiar (Irr/Pec) galaxy populations continuously rise to match the spiral contribution at z similar or equal to 1:0. We use the i(775) - z850 and V606 - i(775) color-magnitude diagrams to constrain the galaxies' formation histories and find that E/S0s show both a population of luminous red galaxies in place at z similar to 1.2 and a bluer and fainter population resembling that of Irr/Pec at similar redshifts."

A new core from Laguna de Tagua Tagua (34 degrees 30' S) provides a sedimentologic, geochemical and palynological record of regional hydrologic balance for the last 46 000 cal. yr BP. According to Our age model, relatively humid conditions Occurred during glacial times before 43500 cal.yr BP and from 40000 to 21 500 cal.yr BP. Reduced moisture conditions and likely lower temperatures occurred from 42 400-40100 cal. yr BP. Higher lake levels, and pollen assemblages with Valdivian rainforest taxa, imply much higher precipitation during glacial times (40 100-21 000 cal. yr BP) compared to today and, therefore, enhanced westerly activity in northern Central Chile. Afterwards, the general decrease in moisture was punctuated by two abrupt arid periods at 21 000-19 500 cal. yr BP and 17 00015 000 cal. yr BP, arid two more humid intervals: 19 500-17 000 (almost coincident with the global Last Glacial Maximum, LGM) and 13 500-11 500 cal. yr BP. The early and mid-Holocene were the most arid periods in Central Chile for the studied time interval. Millennial-scale palaeohydrological reconstructions from Tagua Tagua are consistent with regional climatic records. Copyright (C) 2005 John Wiley & Sons, Ltd."

We use a retrieval scheme originally developed for absolute stellar accelerometry [Connes, R, 1985. Astrophys. Space Sci., 110, 211-255] to extract the velocity signal by Simultaneously taking into account all the lines present in the spectrum. The method allows to measure the Doppler shift induced at a given point by the zonal wind flow, with high precision. The short-wavelength channel (4200-5200 angstrom) probes one scale height higher than the long-wavelength one (5200-6200 angstrom), and we observe statistically significant evidence for stronger winds at higher altitudes. The results show a high dispersion. Globally, we detect prograde zonal winds, with lower limits of 62 and 50 in s(-1) at the regions centered at 200 and 170 km attitude, but approximately a quarter of the measurements indicates null or retrograde winds.

Absolute dimensions of the components are determined with excellent precision ( better than 0.7% in the masses and 0.5% in the radii) for the purpose of testing various aspects of theoretical modeling. We obtain 0.928 +/- 0.006 M. and 1.186 +/- 0.004 R. for the hotter, larger, more massive, and more luminous photometric primary (star A) and 0.870 +/- 0.004 M. and 0.964 +/- 0.004 R. for the cooler, smaller, less massive, and less luminous photometric secondary (star B). A faint, third component contributes 2.6% of the light in V but is not detected in our spectrograms. The effective temperatures and interstellar reddening of the stars are accurately determined from UBV and uvby beta photometry and from analysis of the spectrograms: 5760 +/- 100 K for the primary and 5560 +/- 150 K for the secondary, corresponding to spectral types of G5 and G7, and 0.050 mag for interstellar reddening Eb-y. The orbits are slightly eccentric, and spectral line widths give observed rotational velocities that are not significantly different from synchronous for both components. The components of RW Lac are old, somewhat metal-deficient, low-mass, main-sequence stars with an age of about 11 Gyr, according to models."

The spectrum of the source rises in the whole frequency range sampled, from 2.4 to 24.9 GHz, although the spectral index seems to decrease at the highest frequencies (0.79 +/- 0.04 between 4.3 and 8.9 GHz, and 0.64 +/- 0.06 between 16.1 and 24.9 GHz). This suggests a turnover frequency of around 20 GHz (which is unusual among PNe, whose radio emission usually becomes optically thin at frequencies < 10 GHz), and a relatively high emission measure (1.5 x 10(9) cm(-6) pc). The radio-continuum emission has increased by a factor of similar or equal to 1.26 at 8.4 GHz in 13 yr, which can be explained as expansion of the ionized region by a factor of similar or equal to 1.12 in radius with a dynamical age of similar or equal to 120 yr and at an expansion velocity of similar or equal to 5-40 km s (-1).

The present work offers, for the first time, a very detailed analysis of oxygen and hydrogen isotopic signatures of unusually large ice conglomerations, or ""megacryometeors"", that fell to the ground in Spain during January 2000. The hydrochemical analysis is based on the bulk isotopic composition and systematic selective sampling ( deuterium isotopic mapping) of eleven selected specimens. delta(18)O and delta D (V-SMOW) of all samples fall into the Meteoric Water Line matching well with typical tropospheric values. The distribution of the samples on Craig's line suggests either a variation in condensation temperature and/or different residual fractions of water vapour ( Rayleigh processes). Three of the largest megacryometeors exhibited unequivocally distinctive negative values (delta(18)O = - 17.2 parts per thousand and delta D = - 127 parts per thousand V-SMOW), (delta(18)O = - 15.6 parts per thousand and delta D = - 112 parts per thousand V-SMOW) and (delta(18)O = - 14.4 parts per thousand and delta D =- 100% V-SMOW), suggesting an atmospheric origin typical of the upper troposphere. Theoretical calculations indicate that the vertical trajectory of growth was lower than 3.2 km. During the period in which the fall of megacryometeors occurred, anomalous atmospheric conditions were observed to exist: a substantial lowering of the tropopause with a deep layer of saturated air below, ozone depression and strong wind shear. Moreover, these large ice conglomerations occurred during non-thunderstorm conditions, suggesting an alternative process of ice growth was responsible for their formation."

The water maser spots of this microstructure present a spatial distribution and line-of-sight velocity components that fit extremely well a circular ring of similar or equal to 1 AU radius expanding at similar or equal to 2.5 km s(-1). In particular, we have studied the spatio-kinematics and intensity distribution of the maser emission of an expanding ring observed at arbitrary angles. We construct position-velocity diagrams for the maser spots, calculating the maximum intensity as a function of the impact parameter and then comparing the results with the observations. This is the first time that such well-ordered spatio-kinematical behavior of the water masers is observed and modeled at the very small scale of similar or equal to 1 AU. The VLA2 maser shell is probably produced by an energetic stellar wind that compresses the ambient medium and drives a shock into it. Water maser emission is excited in flattened structures behind the shocks. We speculate that either these kinds of spatio-kinematical microstructures are produced by fluid instabilities within the shocked material or they correspond to nearly round cloudlets (turbulent eddies?) in the ambient medium that were flattened by the expanding shock."

Here we describe the minimal region required for stable replication of a member of the repC family, the low copy-number plasmid pRmeGR4a from Sinorizobium meliloti GR4. This region contains only two genes: one encoding the initiator protein RepC (46.8 kDa) and other, an antisense RNA (67 nt). Mapping of transcriptional start sites and promoter regions of both genes showed that the antisense RNA is nested within the repC mRNA leader. The constitutively expressed countertranscribed RNA (ctRNA) forms a single stem-loop structure that acts as an intrinsic rho-independent terminator. The ctRNA is a strong trans-incompatibility factor and negative regulator of repC expression. Based on structural and functional similarities between members of the repC and repABC families we propose a model of their evolutionary relationship. (c) 2005 Elsevier Inc. All rights reserved."

We have detected an unresolved continuum source [ I20126N(1.3 cm)] nearly coinciding with the strongest peak of the northern double continuum source previously detected at 3.6 cm in the field and suggested to be a radio jet. In addition, we have detected 29 water maser spots, 21 of which are tightly grouped in a cluster of similar or equal to 0.'' 1 size displaced similar or equal to 0.'' 07 (similar or equal to 120 AU) northwest of I20126N(1.3 cm). The relative positions of the masers with respect to I20126N(1.3 cm) have been established with 10 mas of accuracy. The overall spatial distribution and line-of-sight velocity components of the water maser spots associated with I20126N( 1.3 cm) are fully consistent with those previously found by Moscadelli and collaborators through VLBI measurements and interpreted as tracing a conical outflow, with the powering source ( suggested to be traced by a one-sided radio continuum jet) located at the cone vertex. Within this very reasonable scenario, our observations would indicate that the source I20126N( 1.3 cm) is showing the position of the high-mass protostar. Analyzing the spatiokinematic distribution of the VLA water masers, we propose that their motions also show, in addition to proper motions on the order of 100 km s(-1) seen in the plane of the sky, a component of rotation with velocities on the order of 20 km s(-1). The water masers seem then to be both rotating ( as evidenced from their radial velocities) and changing their position in the plane of the sky ( from the proper motions). Within this scenario, some of the water maser spots could be within a rotating circumstellar disk of similar or equal to 170 AU size around a protostar of similar or equal to 20 M-. if it is located at the center of the water maser cluster rather than located at the position of I20126N( 1.3 cm). Then, I20126N( 1.3 cm) would trace one of the two peaks of a two-sided thermal jet, with the high-mass protostar located in between. We think that simultaneous high angular resolution and sensitive multifrequency ( from centimeter to submillimeter wavelengths) observations are the key studies to knowing both the nature of the continuum emission ( one-or two-sided jet?) and the location of the high-mass protostar, which is very relevant for modeling this important object."

Relatively dense taxon sampling for the genera Rhizobium and Mesorhizobium was achieved by generating atpD and recA sequences for six type and 24 reference strains not previously available in GenBank. This phylogeny was used to classify nine nodule isolates from Sesbania exasperata, S. punicea and S. sericea plants native to seasonally flooded areas of Venezuela, and compared with a PCR-RFLP analysis of rrs plus rrl genes and large maximum likelihood rrs and nifH phylogenies. We show that rrs phylogenies are particularly sensitive to strain choice due to the high levels of sequence mosaicism found at this locus. All analyses consistently identified the Sesbania isolates as Mesorhizobium plurifarium or Rhizobium huautlense. Host range experiments on ten legume species coupled with plasmid profiling uncovered potential novel biovarieties of both species. This study demonstrates the wide geographic and environmental distribution of M. plurifarium, that R. galegae and R. huautlense are sister lineages, and the synonymy of R. gallicum, R. mongolense and R. yanglingense. Complex and diverse phylogeographic, inheritance and host-association patterns were found for the symbiotic nifH locus. The results and the analytical approaches used herein are discussed in the context of rhizobial taxonomy and molecular systematics. (c) 2005 Elsevier GmbH. All rights reserved."

The rctA gene product lacks sequence conservation with other proteins of known function but may belong to the winged-helix DNA-binding subfamily of transcriptional regulators. Similar to that of many transcriptional repressors, rctA transcription seems to be positively autoregulated. rctA expression is greatly reduced upon overexpression of another gene, rctB, previously identified as a putative activator of R. edi pSym conjugal transfer. Thus, rctB seems to counteract the repressive action of rctA. rctA homologs are present in at least three other bacterial genomes within the order Rhizobiales, where they are invariably located adjacent to and divergently transcribed from putative virB-like operons. We show that similar to that of R. edi pSym, conjugative transfer of the 1.35-Mb symbiotic megaplasmid A of Sinorhizobium meliloti is also subjected to the inhibitory action of rctA. Our data provide strong evidence that the R. edi and S. meliloti pSym plasmids are indeed self-conjugative plasmids and that this property would only be expressed under optimal, as yet unknown conditions that entail inactivation of the rctA function. The rctA gene seems to represent novel but probably widespread regulatory systems controlling the transfer of conjugative elements within the order Rhizobiales."

Accordingly, 298 patients with rheumatoid arthritis (RA), 143 with systemic lupus erythematosus (SLE), 70 with primary Sjogren's syndrome (pSS) and 110 with Type 1 diabetes (T1D) were studied. The control group consisted of 308 matched healthy individuals. Genotyping of PTPN22 was performed by the real-time polymerase chain reaction technology, using the TaqMan 50'allele discrimination assay. The 1858 T allele was found to be a risk factor for pSS (odds ratio (OR) = 2.42), SLE (OR 2.56), and T1D (OR 1.83). A lower but nonsignificant trend was observed for RA (OR = 1.26).

Our goal is to gain insights in the types of galaxies that give rise to GRBs and the relationship of GRB hosts to high-redshift galaxies selected through more traditional photometric methods. We measure structural properties of our sample from HST observations obtained after the GRB afterglow faded. Fitting exponential disk (typical for spirals) and r(1/4) (typical for ellipticals) models to the surface brightness profiles of eight z < 1.2 bright host galaxies, we find that the disk model is slightly preferred for most hosts, although two galaxies are fit best with an r(1/4) profile. We furthermore measure the central concentrations and asymmetries of all 37 host galaxies using the CAS (concentration, asymmetry, clumpiness) system and compare with values for galaxies in the Hubble Deep Field and systems present on the GRB host images. Our first main conclusion is that GRB hosts exhibit a surprisingly broad diversity of galaxy types. A significant fraction (68%) of host galaxies are situated in a region of the concentration-asymmetry diagram occupied by spirals or peculiar/merging galaxies. Twelve hosts (32%) are situated in the region occupied by elliptical galaxies, having high concentration indices indicative of early types or early types in formation. These results show that GRB host galaxies are not a single morphological type but span the available range of galaxy types seen at high redshift. We also find some evidence for evolution in GRB host galaxy morphology, such that hosts at z > 1 have a relatively high light concentration, indicating that these systems are perhaps progenitors of massive galaxies, or are compact blue star-forming galaxies. We find that GRB hosts at z > 1 are different from the general field population at z > 1 in terms of light concentration, at > 99.5% confidence, yet have sizes similar to the general z > 1 population. This is the opposite of the effect at z < 1, where GRB hosts are smaller than average. We argue that GRB hosts trace the starburst population at high redshift, as similarly concentrated galaxies at z > 2 are undergoing a disproportionate amount of star formation for their luminosities. Furthermore, our results show that GRBs are not only an effective tracer of star formation but are perhaps ideal tracers of typical galaxies undergoing star formation at any epoch, making them perhaps our best hope of locating the earliest galaxies at z > 7."

Although this gamma- ray burst (GRB) is one of the best observed so far in terms of sampling in the time domain, multiwavelength coverage, and polarimetric observations, there is substantial disagreement between different interpretations of data sets on this burst in the literature. We have observed the field of GRB 021004 with the HST at multiple epochs from 3 days until almost 10 months after the burst. With the STIS PRISM and G430L spectroscopy, we cover the spectral region from about 2000 to 5700 angstrom, corresponding to 600-1700 angstrom in the rest frame. From the limit on the flux recovery blueward of the Lyman limit, we constrain the H I column density to be above 1 x 10(18) cm(-2) (5 sigma). On the basis of ACS and NICMOS imaging, we find that the afterglow evolved achromatically within the errors (any variation must be less than 5%) during the period of the HST observations. The color changes observed by other authors during the first 4 days must be related to a stochastic phenomenon superimposed on an afterglow component with a constant spectral shape. This achromaticity implies that the cooling break has remained on the blue side of the optical part of the spectrum for at least 2 weeks after the explosion. The optical-to-X-ray slope beta(OX) is consistent with being the same at 1.4 and 52.4 days after the burst. This indicates that the cooling frequency is constant and, hence, according to fireball models, that the circumburst medium has a constant density profile. The late-time slope of the light curve (alpha(2), F-v proportional to t(-alpha 2)) is in the range alpha(2) = 1.8-1.9 and is inconsistent with a single power law. This could be due to a late-time flattening caused by the transition to nonrelativistic expansion or could be due to excess emission (a ""bump"" in the light curve) about 7 days after the burst. The host galaxy is, like most previously studied GRB hosts, a (very) blue starburst galaxy with no evidence for dust and with strong Ly alpha emission. The star formation rate of the host is about 10 M-circle dot yr(-1) on the basis of both the strength of the UV continuum and the Ly alpha luminosity. The spectral energy distribution of the host implies an age in the range 30-100 Myr for the dominant stellar population. The afterglow was located very close (similar to 100 pc) to the center of the host, implying that the progenitor was possibly associated with a circumnuclear starburst."

We find a break in the J-band light curve at - t(b) = 2.6 +/- 1.0 d ( observer frame). If we assume this is the jet break, we derive a beaming-corrected energy E-gamma similar to (4 divided by 12) x 10(51) erg. This limit shows that GRB050904 is consistent with the Amati and Ghirlanda relations. This detection is consistent with the expected number of GRBs at z > 6 and shows that GRBs are a powerful tool to study the star formation history up to very high redshift."

The results for the distant cluster NGC 3105 is most important because of the still unknown influence of the global metallicity gradient of the Milky Way. These findings confirm that CP stars are present in open clusters of very young ages ( log t >= 6.90) at galactocentric distances up to 11.4 kpc. For all programme clusters the age, reddening, and distance modulus were derived using the corresponding isochrones.

Its applicability to observed frequencies of rotating gamma Doradus stars is discussed taking into account the following aspects: the use of a perturbative approach to compute adiabatic oscillation frequencies; the effect of rotation on the observational Brunt-Vaisala integral determination and finally, the problem of disentangling multiplet-like structures from frequency patterns due to the period spacing expected for high-order gravity modes in asymptotic regime. This analysis reveals that the FRM produces reliable results for objects with rotational velocities up to 70 km s(-1), for which the FRM intrinsic error increases one order of magnitude with respect to the typical FRM errors given in Moya et al. (2005, A&A, 432, 189). Our computations suggest that, given the spherical degree l identification, the FRM may be discriminating for m = 0 modes, in the sense that the method avoids any misinterpretation induced by the presence of rotationally split multiplet-like structures, which reinforces the robustness of the method. However, if l is unknown, such discrimination is not ensured. In order to check the FRM in presence of slow-moderate rotation, we have applied it to the three observed frequencies of the slowly rotating (v sin i = 29 km s(-1)). Doradus star HD 48501."

The breakthrough in our understanding of long-duration GRBs ( those lasting more than similar to 2 s), which ultimately linked them with energetic type Ic supernovae(2-4), came from the discovery of their long-lived X-ray(5) and optical(6,7) 'afterglows', when precise and rapid localizations of the sources could finally be obtained. X-ray localizations have recently become available(8,9) for short ( duration < 2 s) GRBs, which have evaded optical detection for more than 30 years. Here we report the first discovery of transient optical emission (R-band magnitude similar to 23) associated with a short burst: GRB 050709. The optical afterglow was localized with subarcsecond accuracy, and lies in the outskirts of a blue dwarf galaxy. The optical and X-ray(10) afterglow properties 34 h after the GRB are reminiscent of the afterglows of long GRBs, which are attributable to synchrotron emission from ultrarelativistic ejecta. We did not, however, detect a supernova, as found in most nearby long GRB afterglows, which suggests a different origin for the short GRBs."

While for the latter field, including its surrounding we obtain a contribution of 3 per cent of chemically peculiar stars detectable by Delta a photometry (i.e. the magnetic objects of this group), the second field yields about half of this value in good accordance with Maitzen et al.'s finding for NGC 1866, the surrounding field of which has been found to exhibit a very low value of such stars (0.3 per cent). Thus, we are faced with the fact that our incipient impression about a substantially lower appearance of magnetic chemically peculiar stars in the LMC as compared to the Galaxy continues to be valid. Most of the photometrically identified peculiar stars (from their historical origin denominated Ap stars) are located in the domain of the B-type stars. However, this is a selection effect due to the limiting magnitude of our observing conditions impeding the observation of fainter main-sequence stars. In addition to objects showing up as positive deviators in Delta a photometry, we also discuss nine stars which appear opposite the main line of normal stars, and hence are negative deviators. For most of them, the interpretation as emission stars of B-type seems to be appropriate. The statistically relevant number of observations obtained so far in the LMC supports the view that the formation of magnetic peculiar stars has occurred there at a significantly lower rate."

"The application of Pb inhibited the development of mycelia of the saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi (AM) Glomus mosseae and G. deserticola in vitro. The application to soil of 1500 mg kg(-1) of Pb decreases the dry weight, total N, P, Mg and Fe concentration and chlorophyll content of the shoot of E. globulus no inoculated with AM fungi. However, G. deserticola increased the dry weight, total nutrient concentration and chlorophyll content of the shoot, and the percentage of AM root length colonization and the succinate dehydrogenase activity of AM mycelia of E. globulus in presence of 1500 mg kg(-1) of Pb, and these increases were higher when G. deserticola was inoculated together with T. koningii. The application to soil of 3000 mg kg(-1)of Pb decreased the shoot dry weight and AM colonization of E. globulus in all treatments tested. Pb was accumulated in the stem more than in the leaves of E. globulus. In presence of 1500 mg kg-1 of Pb the highest accumulation of this metal in the stem took place when E. globulus was colonized with G. deserticola. In conclusion, the possibility to increase Lead accumulation in stem is very attractive for phytoextraction function, the saprobe fungi, AM and their interaction may have a potential role in elevating phytoextraction efficiency and stimulate plant growth under adverse conditions such as lead contaminated soil."

In this study we investigated the effects of temperature on fungal growth and tested whether the differences in fungal growth were related to the effects of temperature on carbon movement to, or within, the fungus. (.) Growth curves and C uptake-transfer-translocation measurements were obtained for three arbuscular mycorrhizal fungi (AMF) isolates cultured within a 6-30 degrees C temperature range. A series of experiments with a model fungal isolate, Glomus intraradices, was used to examine the effects of temperature on lipid body and 33 P movement, and to investigate the role of acclimation and incubation time. (.) Temperature effects on AMF growth were both direct and indirect because, despite clear independent root and AMF growth responses in some cases, the uptake and translocation of 13 C was also affected within the temperature range tested. Root C uptake and, to a lesser extent, C translocation in the fungus, were reduced by low temperatures (< 18 C). Uptake and translocation of 33 P by fungal hyphae were, by contrast, similar between 10 and 25 C. (.) We conclude that temperature, between 6 and 18 C, reduces AMF growth, and that C movement to the fungus is involved in this response."

According to the effect on each fungal growth parameter, the tested compounds could be classified to be genus and/or species specific or specific, for a certain developmental stage of pre-symbiotic growth. A clear arbuscular mycorrhizal genus specific, and even species specific, effect of some flavonoids was observed. However, this specificity of a flavonoid could not be generalized but differs depending on the pre-symbiotic stage of the AM fungus.

From V and R imaging, initiated similar to 2 days after the GRB trigger and lasting up to three weeks, we detect no variable object inside the small Swift XRT X-ray error circle down to 2 sigma limits of V = 26.5 and R = 25.1. The X-ray error circle includes a giant elliptical galaxy at z = 0.225, which has been proposed as the likely host of this GRB. Our limits indicate that if the GRB originated at, z = 0.225 any supernova-like event accompanying the GRB would have to be over 100 times fainter than normal Type Ia SNe or Type Ic hypernovae, 5 times fainter than the faintest known Ia or Ic SNe, and fainter than the faintest known Type II SNe. Moreover, we use the optical limits to constrain the energetics of the GRB outflow. Simple models indicate that unless the intrinsic energy in the outflow from GRB 050509B was <= 10(51) ergs, there was very little radioactive material with efficient decay timescales for generating a large luminosity. These limits strongly constrain progenitor models for this short GRB."

A very large dataset composed of 4722 photometric measurements was collected at six observatories in Europe and America.

From uvby beta photometry and evolutionary tracks it appears to be a Pop. I star with M = 1.75 M., located in the middle of the instability strip, close to the Zero-Age Main Sequence.

Under phosphate-limiting conditions of growth, S. meliloti replaces its phospholipids by membrane lipids that do not contain any phosphorus in their molecular structure and, in S. meliloti, these phosphorus-free membrane lipids are sulphoquinovosyl diacyl-glycerols (SL), ornithine-containing lipids (OL), and diacylglyceryl-N,N,N-trimethylhomoserines (DGTS). In earlier work, we demonstrated that neither SL nor OL are required for establishing a nitrogen-fixing root nodule symbiosis with alfalfa. We now report the identification of the two structural genes btaA and btaB from S. meliloti required for DGTS biosynthesis. When the sinorhizobial btaA and btaB genes are expressed in Escherichia coli, they cause the formation of DGTS in this latter organism. A btaA-deficient mutant of S. meliloti is unable to form DGTS but can form nitrogen-fixing root nodules on alfalfa, demonstrating that sinorhizobial DGTS is not required for establishing a successful symbiosis with the host plant. Even a triple mutant of S. meliloti, unable to form any of the phosphorus-free membrane lipids SL, OL, or DGTS is equally competitive for nodule occupancy as the wild type. Only under growth-limiting concentrations of phosphate in culture media did mutants that could form neither OL nor DGTS grow to lesser cell densities."

One important drug target in these organisms is sterol biosynthesis. In these organisms the main endogenous sterols are ergosta- and stigmata-like compounds in contrast to the situation in mammals, which have cholesterol as the sole sterol. In this paper we discuss the design, synthesis and evaluation of potential transition state analogues of the enzyme Delta(24(25))-methyltransferase (24-SMT). This enzyme is essential for the biosynthesis of ergosterol, but not required for the biosynthesis of cholesterol. A series of compounds were successfully synthesised in which mimics of the S-adenosyl methionine co-factor were attached to the sterol nucleus. Compounds were evaluated against recombinant Leishmania major 24-SMT and the parasites L. donovani and Trypanosoma cruzi in vitro, causative organisms of leishmaniasis and Chagas disease, respectively. Some of the-compounds showed inhibition of the recombinant Leishmania major 24-SMT and induced growth inhibition of the parasites. Some compounds also showed anti-parasitic activity against L. donovani and T cruzi, but no inhibition of the enzyme. In addition, some of the compounds had anti-proliferative activity against the bloodstream forms of Trypanosoma brucei rhodesiense, which causes African trypanosomiasis.

The great interest of this object lies in that three important characteristics coexist: cluster membership, binarity and pulsation. Its binarity and the delta Sct-type pulsations of one component were detected in the course of several Strmgren photometric campaigns. The frequency analysis of all the uvby out-of-eclipse data reveals a clear frequency of 19.5974 cd(-1) as well as the existence of other high values in the range 18-20 cd(-1). We have also carried out a first evaluation of the binary parameters and determined a value of 5.702 d for the orbital period. An additional potential interest of HD172189 resides in its location in the field of view of the COROT mission and, therefore, this star is an excellent candidate for becoming a target for asteroseismology."

Recent studies suggest that high-mass stars may form through accretion of material from a circumstellar disk(3), in essentially the same way as low-mass stars form, rather than through the merging of several low-mass stars(4). There is as yet, however, no conclusive evidence(5,6). Here we report the presence of a flattened disk-like structure around a massive 15M(.) protostar in the Cepheus A region, based on observations of continuum emission from the dust and line emission from the molecular gas. The disk has a radius of about 330 astronomical units (AU) and a mass of 1 to 8 M(: It is oriented perpendicular to, and spatially coincident with, the central embedded powerful bipolar radio jet, just as is the case with low-mass stars, from which we conclude that high-mass stars can form through accretion."

The radio galaxy is known to reside within a large galaxy overdensity ( both in physical extent and density contrast). There is good evidence that this `` protocluster'' region is the progenitor of a present- day rich galaxy cluster. TN J1338 is the dominant galaxy in the protocluster in terms of size and luminosity ( in both the optical and near- infrared) and therefore seems destined to evolve into the brightest cluster galaxy. The high spatial resolution ACS images reveal several kiloparsec- scale features within and around the radio galaxy. The continuum light is aligned with the radio axis and is resolved into two clumps in the i(775) and z(850) bands. These components have luminosities similar to 10(9) L-circle dot and sizes of a few kpc. The estimated nebular continuum, scattered light, synchrotron- and inverse Compton - scattering contributions to the aligned continuum light are only a few percent of the observed total, indicating that the observed flux is likely dominated by forming stars. The estimated star formation rate for the whole radio galaxy is similar to 200M(circle dot) yr(-1). A simple model in which the jet has triggered star formation in these continuum knots is consistent with the available data. A striking, but small, linear feature is evident in the z850 aligned light and may be indicative of a large- scale shock associated with the advance of the radio jet. The rest of the aligned light also seems morphologically consistent with star formation induced by shocks associated with the radio source, as seen in other high- z radio galaxies ( e. g., 4C 41.17). An unusual feature is seen in Ly alpha emission. A wedge- shaped extension emanates from the radio galaxy perpendicularly to the radio axis. This `` wedge'' naturally connects to the surrounding asymmetric, large- scale (similar to 100 kpc) Ly alpha halo. We posit that the wedge is a starburst- driven superwind associated with the first major epoch of formation of the brightest cluster galaxy. The shock and wedge are examples of feedback processes due to both active galactic nucleus and star formation in the earliest stages of massive galaxy formation."

Upon processing and clustering the set of 1893 accepted sequences was reduced to 697 clusters consisting of 452 singletons and 245 contigs. Functional categories were assigned based on BLAST searches against a database of the eukaryotic orthologous groups of proteins (KOG). Thirty six percent of the generated sequences showed no hits against the KOG database and 39.6% presented similarity to the KOG classes corresponding to translation, ribosomal structure and biogenesis. The most populated cluster contained 45 ESTs homologous to members of the glucose transporter family. This fact can be immediately correlated to the reported Phytomonas dependence on anaerobic glycolytic ATP production due to the lack of cytochrome-mediated respiratory chain. In this context, not only a number of enzymes of the glycolytic pathway were identified but also of the Krebs cycle as well as specific components of the respiratory chain. The data here reported, including a few hundred unique sequences and the description of tandemly repeated motifs and putative transcript stability motifs at untranslated mRNA ends, represent an initial approach to overcome the lack of information on the molecular biology of this organism.

Our extensive dataset is a factor of 2 larger and spans a time interval similar to 4 times longer than the ones considered previously for this GRB afterglow; this allows a more thorough analysis of its light curve and of the GRB host galaxy properties. The afterglow light curves show a single power-law temporal decline, modified at late times by light from a host galaxy with moderate intrinsic extinction, and possibly by an emerging supernova (SN). The afterglow evolution is interpreted within the classical ""fireball"" scenario as a weakly collimated adiabatic shock propagating in the interstellar medium. The presence of a SN light curve superimposed on the non-thermal afterglow emission is investigated: while in the optical bands no significant contribution to the total light is found from a SN, the NIR J-band data show an excess which is consistent with a SN as bright as the known hypernova SN1998bw. If the SN interpretation is true, this would be the farthest GRB-associated SN, as well as the farthest core-collapse SN, discovered to date. However, other possible explanations of this NIR excess are also investigated. Finally, we studied the photometric properties of the host, and found that it is likely to be a slightly reddened, subluminous, extreme starburst compact galaxy, with luminosity similar to 0.1 L-star, an age of similar to 0.5 Gyr and a specific Star Formation Rate (SFR) of approximate to 30 M-circle dot yr(-1) (L/L-star)(-1).

(AM) colonized and noncolonized clover roots on the number of entry points and percentage of root colonization of tomato (Lycopersicum esculentum L.) by Gigaspora rosea, Gi margarita, Glomus mosseae and G. intrarradices symbionts was determined. With fungi of both genera, a correlation between the number of entry points and the percentage of root colonization was found in the presence of some of the tested flavonoids. The flavonoids acacetin and rhamnetin, present in AM clover roots, inhibited the formation of AM penetration structures and the AM colonization of tomato roots, whereas the flavonoid 5,6,7,8,9-hydroxy chalcone, which could not be detected in AM clover root, inhibited both parameters. The flavonoid quercetin, which was present in AM clover roots, stimulated the penetration and root colonization of tomato by Gigaspora. However, the flavonoids 5,6,7,8-hydroxy-4'-methoxy flavone and 3,5,6,7,4'-hydroxy flavone, which was not found in AM clover root, increased the number of entry points and the AM colonization of tomato roots by Gigaspora. These results indicated that flavonoids could be implicated in the process of regulation of AM colonization in plant root, but its role is highly complex and depend not only on flavonoids, but also on AM fungal genus or even species.

Trypanosoma rangeli is not pathogenic for humans but shows a high immunological cross-reactivity with Trypanosoma cruzi, the causative agent of Chagas' disease that affects more than 17 million people throughout the world. Recent studies have suggested that T. cruzi KMP-11 antigen could be a good candidate for the induction of immunoprotective cytotoxic responses against T. cruzi natural infection. In the present paper the genes coding for the T. rangeli kinetoplastid membrane protein-11 have been characterized. The results show that the locus encoding this protein is formed by 4 gene units measuring 550 nucleotides in length, organized in tandem, and located in different chromosomes in KP1(+) and KP1(-) strains. The gene units are transcribed as a single mRNA of 530 nucleotides in length. Alignment of the T. rangeli KMP-11 deduced amino acid sequence with the homologous KMP-11 protein from T. cruzi revealed an identity of 97%.

We use multicolor imaging with the Advanced Camera for Surveys on the Hubble Space Telescope to determine these sizes and surface brightnesses. Using three different estimates of the surface brightnesses, we find that we reliably estimate the surface brightness for the galaxies in our sample with a scatter of < 0.2 mag and with systematic shifts of <= 0.05 mag. We construct samples of galaxies with early- type morphologies in both clusters. For each cluster, we use a magnitude limit in a band that closely corresponds to the rest- frame B, to magnitude limit of M-B = - 18: 8 at z = 0, and select only those galaxies within the color- magnitude sequence of the cluster or by using our spectroscopic redshifts. We measure evolution in the rest- frame B surface brightness and find - 1: 41 +/- 0: 14 mag from the Coma Cluster of galaxies for RDCS J1252.9 - 2927 and - 0: 90 +/- 0: 12 mag of evolution for RX J0152.7 - 1357, or an average evolution of ( - 1: 13 +/- 0: 15) z mag.

We find no statistically significant evolution in this scatter, although an increase in the scatter could be expected.

However, interstellar clouds are observed as projected two-dimensional images, and the projection of a three-dimensional fractal distorts its measured properties. Here we use simulated fractal clouds to study the relationship between the three-dimensional fractal dimension (D-f) of modeled clouds and the dimension resulting from their projected images. We analyze different fractal dimension estimators: the correlation and mass dimensions of the clouds and the perimeter-based dimension of their boundaries (D-per). We find the functional forms relating Df with the projected fractal dimensions, as well as their dependence on the image resolution, which allow us to estimate the ""real'' Df value of a cloud from its projection. The application of these results to Orion A indicates in a self-consistent way that 2.5 less than or similar to D-f less than or similar to 2.7 for this molecular cloud, a value higher than the result D-per + 1 similar or equal to 2.3 sometimes assumed in the literature for interstellar clouds."

Compounds that inhibited the enzyme, also reduced the levels of steroids and caused growth inhibition of L. mexicana promastigotes. However there was a lower correlation between inhibition of the enzyme and growth inhibition of the intracellular parasites, possibly due to delivery problems.

We focus on INTEGRAL Revolution number 48 when the source was found to exhibit a new type of variability as preliminarily reported in Hannikainen ( 2003, A&A, 411, L415). The variability pattern, which we name., is characterized by a pulsing behaviour, consisting of a main pulse and a shorter, softer, and smaller amplitude precursor pulse, on a timescale of 5 min in the JEM-X 3-35 keV lightcurve. We also present simultaneous RXTE data. From a study of the individual RXTE/PCA pulse profiles we find that the rising phase is shorter and harder than the declining phase, which is opposite to what has been observed in other otherwise similar variability classes in this source. The position in the colour-colour diagram throughout the revolution corresponds to State A (Belloni et al. 2000, A&A, 355, 271) but not to any previously known variability class. We separated the INTEGRAL data into two subsets covering the maxima and minima of the pulses and fitted the resulting two broadband spectra with a hybrid thermal-non-thermal Comptonization model. The fits show the source to be in a soft state characterized by a strong disc component below similar to 6 keV and Comptonization by both thermal and non-thermal electrons at higher energies."

The simulation is made by convolving real spectra with a Gaussian function, with sigma (the full width at half maximum) related to the final spectral resolution. The accuracy with which the stellar parameters are determined indicates that the method may be applied to typical objective-prism spectra. We show that changes in the spectral resolution do not significantly affect the stellar parameters obtained with this method for early-type stars, whereas for later-type stars an improved approach is necessary."

The spectra pertain to the inner similar to 300 pc in radius, and thus sample the central kinematics and stellar populations of active galaxies. The data are used to measure stellar velocity dispersions (sigma(star)) with both cross-correlation and direct fitting methods. These measurements are found to be in good agreement with each other and with those in previous studies for objects in common. The CaT equivalent width is also measured. We find average values and sample dispersions of W-CaT of 4.6 +/- 2.0, 7.0 +/- 1.0 and 7.7 +/- 1.0 angstrom for Seyfert 1s, Seyfert 2s and normal galaxies, respectively. We further present an atlas of [S III]lambda 9069 emission-line profiles for a subset of 40 galaxies.

Simulations and independent comparisons of our visually derived morphologies indicate that ACS allows one to distinguish between E, S0, and spiral morphologies down to z(850) = 24, corresponding to L/L* 0.21 and 0.30 at z = 0.83 and 1.24, respectively. We adopt density and radius estimation methods that match those used at lower redshift in order to study the evolution of the MDR and MRR. We detect a change in the MDR between 0: 8 < z < 1.2 and that observed at z similar to 0, consistent with recent work; specifically, the growth in the bulge-dominated galaxy fraction, f(E+S0), with increasing density proceeds less rapidly at z similar to 1 than it does at z similar to 0. At z similar to 1 and Sigma >= 500 galaxies Mpc(-2), we find < f(E+S0)> = 0.72 +/- 0.10. At z similar to 0, an E + S0 population fraction of this magnitude occurs at densities about 5 times smaller. The evolution in the MDR is confined to densities Sigma greater than or similar to 40 galaxies Mpc(-2) and appears to be primarily due to a deficit of S0 galaxies and an excess of Sp+Irr galaxies relative to the local galaxy population. The f(E)-density relation exhibits no significant evolution between z = 1 and 0. We find mild evidence to suggest that the MDR is dependent on the bolometric X-ray luminosity of the intracluster medium. Implications for the evolution of the disk galaxy population in dense regions are discussed in the context of these observations."

The overexpression of this transporter reduced the accumulation of fluorescent glycerophospholipid analogs, increased the exocytic activity, and decreased infectivity of macrophage, but did not confer resistance to drugs. Together, these results suggest that this new ABC transporter plays a role in phospholipid trafficking, which may be modifying the vesicular trafficking and the infectivity of the parasite.

The resolved g - r, r - i, and i - z color maps reveal a prominent blue core identifying this galaxy as a ""typical'' case study, exhibiting variations of 0.5 - 1.0 mag in color between the center and the outer regions, opposite to the expectations of reddened metallicity- induced gradients in passively evolved elliptical galaxies. From a Magellan-Clay telescope spectrum we secure the galaxy redshift at z = 0.624. We find a strong X-ray source coincident with the spheroid galaxy. Spectral features and a high X-ray luminosity indicate the presence of an active galactic nucleus (AGN) in the galaxy. However, a comparison of the X-ray luminosity to a sample derived from the Chandra Deep Field - South displays L-X to be comparable to type 1/QSO galaxies while the optical flux is consistent with a normal star-forming galaxy.

Radial and tangential arcs delineate the critical curves in unprecedented detail, and many small counterimages are found near the center of mass. We construct a flexible light deflection field to predict the appearance and positions of counterimages. The model is refined as new counterimages are identified and incorporated to improve the model, yielding a total of 106 images of 30 multiply lensed background galaxies, spanning a wide redshift range, 1.0 < z < 5.5. The resulting mass map is more circular in projection than the clumpy distribution of cluster galaxies, and the light is more concentrated than the mass within r < 50 kpc h(-1). The projected mass profile flattens steadily toward the center with a shallow mean slope of dlog &USigma;/dlog r &SIME; -0.55 &PLUSMN; 0.1, over the observed range r < 250 kpc h(-1), matching well an NFW profile, but with a relatively high concentration, C-vir = 8.2(1.8)(+2.1). A softened isothermal profile (r(core) = 20 +/- 2"") is not conclusively excluded, illustrating that lensing constrains only projected quantities. Regarding cosmology, we clearly detect the purely geometric increase of bend angles with redshift. The dependence on the cosmological parameters is weak owing to the proximity of A1689, z = 0.18, constraining the locus, Omega(M) + Omega(Lambda) less than or equal to 1.2. This consistency with standard cosmology provides independent support for our model, because the redshift information is not required to derive an accurate mass map. Similarly, the relative fluxes of the multiple images are reproduced well by our best-fitting lens model."

Here we present the spectroscopic discovery of two M 32 twins in the massive galaxy cluster Abell 1689. As these objects are so rare, this is an important step towards a better understanding of the nature of compact galaxies. The two M 32 twins had first been detected within our photometric search for ultra compact dwarf galaxy (UCDs) candidates in A1689 (Mieske et al. 2004b, AJ, 128, 1529) with the Advanced Camera for Surveys (ACS). Their luminosities (M-V similar or equal to - 17 mag) are very similar to M 32 and their surface brightness profiles are consistent with that of M 32 projected to A1689' s distance. From our ACS imaging we detect several fainter compact galaxy candidates with luminosities intermediate between M 32 and the Fornax UCDs. If spectroscopically confirmed as cluster members, this would almost close the gap in the mag-mu plane between the region of UCDs and the compact ellipticals, implying a sequence of faint compact galaxies well separated from that of dwarf ellipticals."

Spatially resolved spectral properties	MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY		English	Article						galaxies : active; galaxies : nuclei; galaxies : Seyfert; galaxies : statistics; galaxies : stellar content	DWARF SEYFERT NUCLEI; NEARBY GALAXIES; STAR-FORMATION; EMISSION; SEARCH; STARBURST; CLUSTER; ATLAS	"In a recently completed survey of the stellar population properties of low-ionization nuclear emission-line regions (LINERs) and LINER/H II transition objects (TOs), we have identified a numerous class of galactic nuclei which stand out because of their conspicuous 10(8-9) yr populations, traced by high-order Balmer absorption lines and other stellar indices. These objects are called 'young-TOs', because they all have TO-like emission-line ratios. In this paper we extend this previous work, which concentrated on the nuclear properties, by investigating the radial variations of spectral properties in low-luminosity active galactic nuclei (LLAGNs). Our analysis is based on high signal-to-noise ratio (S/N) long-slit spectra in the 3500-5500 Angstrom interval for a sample of 47 galaxies. The data probe distances of typically up to 850 pc from the nucleus with a resolution of similar to100 pc (similar to1 arcsec) and S/N similar to 30. Stellar population gradients are mapped by the radial profiles of absorption-line equivalent widths and continuum colours along the slit. These variations are further analysed by means of a decomposition of each spectrum in terms of template galaxies representative of very young (less than or equal to10(7) yr), intermediate age (10(8-9) yr) and old (10(10) yr) stellar populations. This study reveals that young-TOs also differ from old-TOs and old-LINERs in terms of the spatial distributions of their stellar populations and dust. Specifically, our main findings are as follows. (i) Significant stellar population gradients are found almost exclusively in young-TOs. (ii) The intermediate age population of young-TOs, although heavily concentrated in the nucleus, reaches distances of up to a few hundred pc from the nucleus. Nevertheless, the half width at half-maximum of its brightness profile is more typically 100 pc or less. (iii) Objects with predominantly old stellar populations present spatially homogeneous spectra, be they LINERs or TOs. (iv) Young-TOs have much more dust in their central regions than other LLAGNs. (v) The B-band luminosities of the central less than or similar to1 Gyr population in young-TOs are within an order of magnitude of M-B=-15, implying masses of the order of similar to10(7)-10(8) M-circle dot. This population was 10-100 times more luminous in its formation epoch, at which time young massive stars would have completely outshone any active nucleus, unless the AGN too was brighter in the past."

The importance of this study in comparison with previous ones is that the Lindroos sample is not X-ray selected so we avoid a possible bias towards fast rotators. In this preliminary study we have monitored eleven stars in the UBVRI bands during two campaigns of ten consecutive nights each. Eight of the observed PTTSs show periodic modulations in their lightcurves and the derived periods range from 1.9 d to 8.0 d. The comparison of these results with theoretical rotational tracks based on disk-star locking theory shows that star-disk decoupling times of 1-20 Myr could reproduce the rotational properties of the targets, assuming an initial rotation period of similar to8 d and a mass of 1 M-circle dot. We have studied the rotation-activity relations of Lindroos PTTSs and compared them with those found in other groups of PMS and zero-age main-sequence (ZAMS) similar to1 M-circle dot stars. The Lindroos sample displays activity-rotation relations very similar to those found in TTSs. It contains a mixture of very active stars, with L-X/L-bol ratios close to the saturation level of -3, and less active (unsaturated) stars. This could be the result of different star-disk decoupling times. Future monitoring of a larger and unbiased sample of PTTS will be important to confirm the significance of these results."

A break in the afterglow light curve is seen approximately 1 day from the onset of the burst. The light curve displays a significant deviation from a simple broken power-law with a bright 1.5 mag bump with a duration of 2-3 days. The optical/near-infrared spectral energy distribution is best fit with a power-law with index beta=-0.36+/-0.12 reddened by an SMC-like extinction law with (a modest) A(V)=0.34+/-0.04. In addition, we present deep spectroscopic observations obtained with the Very Large Telescope. The redshift measured via metal absorption lines in the OA is z=2.658+/-0.004. Based on the damped Lyalpha absorption line in the OA spectrum we measure the H. column density to be log N(H I)=21.6+/-0.2. This confirms the trend that GRBs tend to be located behind very large H. column densities. The resulting dust-to-gas ratio is consistent with that found in the SMC, indicating a low metallicity and/or a low dust-to-metal ratio in the burst environment. We find that a neighbouring galaxy, at a separation of only 1.""2, has z=0.841+/-0.001, ruling it out as the host of GRB 030429. The small impact parameter of this nearby galaxy, which is responsible for Mg II absorption in the OA spectrum, is in contrast to previous identifications of most QSO absorption-selected galaxy counterparts. Finally, we demonstrate that the OA was not affected by strong gravitational lensing via the nearby galaxy."

It appears that the star is part of a double line binary system, with a period of 1.801 d, corresponding to twice the period of the photometric variations. Hence the star is an ellipsoidal variable. The system is probably synchronized. The physical parameters of both components were derived through two independant methods, one based on evolutionary tracks, the other being the result of the behaviour of light curves in a close binary system. After removing the ellipsoidal variations, 3 frequencies are detected in the photometric data: 8.56, 14.51 and 16.42 d(-1), while 2 additional frequencies are also possible: 10.96 and 12.11 d(-1).

The (CO)-C-13 emission of the same region was observed with the IRAM 30 m telescope and optical spectroscopy of several H.. regions in the area were obtained with the Calar Alto 3.5 m telescope. We recovered with the interferometer about 50% of the (CO)-C-12(1-0) total emission that had been earlier measured with single dish observations (Lisenfeld 2002, A&A, 394, 823), indicating that about half of the molecular gas is distributed on spatial scales larger than about 10-15"" (corresponding to 4-6 kpc) to which PdBI is not sensitive. We find two main areas of CO emission: (i) an elongated region towards the area known as SQ B where a Tidal Dwarf Galaxy could currently be forming and (ii) a barely resolved area at the tip of the optical tidal arm. Both regions follow dust lanes visible on HST images and their CO peak coincides spatially exactly with the maximum of the Ha line emission. In SQ B, there is furthermore very good kinematical agreement between the CO, Ha and HI components. We conclude from these coincidences that the gaseous matter found in quantities in the area is physically associated to the optical tidal tail and thus that the intergalactic atomic hydrogen there was expelled from NGC 7319. Its origin had previously been much debated. Furthermore, the relatively high oxygen abundances ( about solar) estimated from the optical spectra of the H.. regions imply that the gas feeding the star formation originated from the inner regions of the parent galaxy. In SQ B, we derive from different tracers a star formation rate, corrected for dust extinction-which is important in the area-of 0.5 M-circle dot/yr, i. e. one of the highest values so far measured outside galaxies. The inferred molecular gas consumption time of 0.5 Gyr lies in the range of values found for spiral and starburst galaxies. On the other hand, the ratio of (CO)-C-12/(CO)-C-13 > 25 is much higher than the values found in disks of spiral galaxies. A relatively low opacity for the (CO)-C-12 gas is the most likely reason."

In addition, we present BOOTES-1 wide-field observations at the time of the occurrence of the burst. First observations at ESO started 0.2 days after the event when the gamma ray burst ( GRB) afterglow was at a magnitude of R similar to 19 and continued until the afterglow had faded below the detection threshold (R> 26). No underlying host galaxy was found. The optical light curve shows a break around 0.8 days after the burst, which is achromatic within the observational errors, supporting the view that it was due to a jetted explosion. Close to the break time the degree of linear polarization of the afterglow light was less than 1.1%, which favors a uniform-jet model rather than a structured one. VLT spectra show two absorption line systems at redshifts z = 1.962 +/- 0.001 and 1.986 +/- 0.001, placing the lower limit for the redshift of the GRB close to 2. We emphasize that the kinematics and the composition of the absorbing clouds responsible for these line systems are very similar to those observed in the afterglow of GRB 021004. This corroborates the picture in which at least some GRBs are physically related to the explosion of a Wolf-Rayet star."

Absolute dimensions of the components are determined with high precision (better than 1.5% in the masses and radii) for the purpose of testing various aspects of theoretical modeling. We obtain 2.005 +/- 0.029 M-circle dot and 2/345 +/- 0.012 R-circle dot for the hotter, but smaller, less massive and less luminous photometric primary (star A), and 2.234 +/- 0.026 M-circle dot and 3.385 +/- 0.026 R-circle dot for the cooler, larger, more massive and more luminous photometric secondary (star B). The effective temperatures and interstellar reddening of the stars are accurately determined from uvbybeta photometry: 8375 +/- 150 K for the primary, 8150 +/- 150 K for the secondary - corresponding to spectral types of A3m and A4m - and 0.058 mag for Eb-y. The metallic-lined character of the stars is revealed by high-resolution spectroscopy and uvbybeta photometry. The orbits are circular, and spectral line widths give observed rotational velocities that are synchronous with the orbital motion for both components. The components of V885 Cyg are main-sequence stars with an age of about 500 Myr according to models. Our estimate of the age of this system would seem to favor the hydrodynamic damping formalism of Tassoul & Tassoul in this particular case, since both the components' spins are synchronous and the orbit is circular."

A. Herrera-Cervera, J. M. Sanjuan-Pinilla, J. Olivares, and J. Sanjuan, J. Bacteriol. 180:4583-4590, 1998) was modified to improve its reliability and prevent selection of undesired false mob clones. By following this modified approach, we were able to identify two functional mob regions in the genome of Rhizobium etli CFN42. One corresponds to the recently characterized transfer region of the nonsymbiotic, self-transmissible plasmid pRetCFN42a (C. Tun-Garrido, P. Bustos, V. Gonzalez, and S. Brom, J. Bacteriol. 185:1681-1692, 2003), whereas the second mob region belongs to the symbiotic plasmid pRetCFN42d. The new transfer region identified contains a putative oriT and a typical conjugative (tra) gene cluster organization. Although pRetCFN42d had not previously been shown to be self-transmissible, mobilization of cosmids containing this tra region required the presence of a wild-type pRetCFN42d in the donor cell; the presence of multiple copies of this mob region in CFN42 also promoted conjugal transfer of the Sym plasmid pRetCFN42d. The overexpression of a small open reading frame, named yp028, located downstream of the putative relaxase gene traA, appeared to be responsible for promoting the conjugal transfer of the R. etli pSym under laboratory conditions. This yp028-dependent conjugal transfer required a wild-type pRetCFN42d traA gene. Our results suggest for the first time that the R. etli symbiotic plasmid is self-transmissible and that its transfer is subject to regulation. In wild-type CFN42, pRetCFN42d tra gene expression appears to be insufficient to promote plasmid transfer under standard laboratory conditions; gene yp028 may play some role in the activation of conjugal transfer in response to as-yet-unknown environmental conditions."

The mean values of the degree of linear polarization (P) and its position angle (theta) resulting from our campaign are <P> = 1.18 +/- 0.10% and <theta> = 148.7degrees +/- 2.3degrees, after correcting for Galactic interstellar polarization. Our VLT data set is most naturally described by a constant degree of linear polarization and position angle, nonetheless a slow theta evolution cannot be entirely ruled out by our data. The VLT monitoring campaign did not reveal either a significant theta rotation respect to the Keck spectropolarimetric observations performed similar to0.25 days after the GRB (Barth et al. 2003). However, <P> is a factor of two lower than the polarization degree measured from Keck. Additionally, the VLT polarization data allowed us to construct an accurate V-band light curve. The V-band photometric data revealed a smooth light curve with a break located between the last Keck and our first VLT polarimetric measurement, 0.33 < t(break,V) < 0.88 days after the GRB.

Stromal invasion was found in only one area where neoplastic follicles coalesced. Granulosa cells had atypical, bizarre TP53 positive nuclei with hyperchromatism, abundant mitoses and numerous hyaline globules. The contralateral ovary was normal. From the age of 10 years, the patient had a complex medical history of multiple tumors, including telangiectatic osteosarcoma, typical and malignant phyllodes tumor, reticulohistiocytoma of skin, carcinomas of the breast and lipo- and leiomyosarcoma. The female genital tract also harbored myometrial leiomyomas and an early endometrial carcinoma. Retrospective histologic study of all mesenchymal neoplasms in this patient showed, the conspicuous presence of similar bizarre TP53 positive cells with hyaline globules in all the mesenchymal neoplasms. In the genetic study, a germline p53 gene mutation was detected in exon 10, codon 336, generating a stop codon in the oligomerization domain of the protein (E336X). A further p53 mutation was found in exon 7 in the granulosa cell tumor. Mutation occurred de novo since there was no history of tumors in any family members, all of whom had a wild-type p53. Although this patient shows a typical tumor phenotype of Li Fraumeni syndrome, the germline mutation corresponded to a highly unusual mutated domain, which is similar to the one found in childhood malignant adrenocortical tumor; also a rare neoplasm that originates in adrenocortical cells; which are closely related, both functionally and embryologically, to granulosa cells."

Azasterols are a known class of (S)-adenosyl-L-methionine: Delta(24)-sterol methltransferase(24-SMT) inhibitors in fungi, plants, and some parasitic protozoa. The compounds prepared showed activity at micromolar and nanomolar concentrations when tested against Leishmania spp. and Trypanosoma spp. The enzymatic and sterol composition studies indicated that the most active compounds acted by inhibiting 24-SMT. The role of the free hydroxyl group at position 3 of the sterol nucleus was also probed. When an acetate was attached to the 3beta-OH, the compounds did not inhibit the enzyme but had an effect on parasite growth and the levels of sterols in the parasite, suggesting that the acetate group was removed in the organism. Thus, an acetate group on the 3beta-OH may have application as a prodrug. However, there may be an additional mode(s) of action for these acetate derivatives. These compounds were shown to have ultrastructural effects on Leishmania amazonensis promastigote membranes, including the plasma membrane, the mitochondrial membrane, and the endoplasmic reticulum. The compounds were also found to be active against the bloodstream form (trypomastigotes) of Trypanosoma brucei rhodesiense, a causative agent of African trypanosomiasis."

Case report	BMC INFECTIOUS DISEASES		English	Article							CUTANEOUS LEISHMANIASIS; TRAVELERS	"Background: The question ""Where have you been?"" is a common one asked by doctors in Northern Europe and America when faced with clinical symptoms not typical of their country. This question must also arise in the clinics of developing countries in which non-autochthonous cases such as the one described here can appear. Important outbreaks of Leishmania infantum have been recorded in the last decade in several Latin American countries but its presence has not yet been recorded in Argentina. We report the first case of visceral leishmaniasis owing to L. infantum in this country. Case presentation: A 71-year-old Spanish woman who has been living in Mendoza, Argentina, during the last 40 years presented with a history of high fever and shivering, anemia, leukopenia and splenomegaly over two years. Argentinian doctors did not suspect visceral leishmaniasis even when the histological analysis revealed the presence of ""intracytoplasmatic spheroid particles compatible with fungal or parasitic infection"". After a serious deterioration in her health, she was taken to Spain where she was evaluated and visceral leishmaniasis was established. Specific identification of the parasite was done by PCR-ELISA, isoenzyme electrophoresis and RAPD-PCR. Conclusion: We would like to point out that: i) cases such as the one described here, which appear in non-endemic areas, can pass unnoticed by the clinical physician. ii) in countries in which these introduced cases reside, in-depth parasitological studies are required into vectors and possible reservoirs to rule out the rare case of local infection and, once infection has taken place, to ensure that this does not spread by anthroponotic transmission or a competent reservoir."

The libraries were constructed from trypomastigote and amastigotes, using a spliced leader primer to synthesize the cDNA second strand, thus selecting for full-length cDNAs. Since the libraries were not normalized nor pre-screened, we compared the representation of transcripts between the two using a statistical test and identify a subset of transcripts that show apparent differential representation. A non-redundant set of 1619 reconstructed transcripts was generated by sequence clustering. This dataset was used to perform similarity searches against protein and nucleotide databases. Based on these searches, 339 sequences could be assigned a putative identity. One thousand one-hundred and sixteen sequences in the non-redundant clustered dataset (68.8%) are new expression tags, not represented in the T cruzi epimastigote ESTs that are in the public databases.

The origin of the survey, infrared and radio observations, data-reduction and optical identifications are briefly reviewed, and a summary of the area covered and the completeness limit for each infrared band is given. A detailed discussion of the band-merging and optical association strategy is given. The total Catalogue consists of 3762 sources. 23 per cent of the 15-mum sources and 75 per cent of the 6.7-mum sources are stars. For extragalactic sources observed in three or more infrared bands, colour-colour diagrams are presented and discussed in terms of the contributing infrared populations. Spectral energy distributions (SEDs) are shown for selected sources and compared with cirrus, M82 and Arp220 starburst, and active galactic nuclei (AGN) dust torus models. Spectroscopic redshifts are tabulated, where available. For the N1 and N2 areas, the Isaac Newton Telescope ugriz Wide Field Survey permits photometric redshifts to be estimated for galaxies and quasars. These agree well with the spectroscopic redshifts, within the uncertainty of the photometric method [similar to10 per cent in (1 + z) for galaxies]. The redshift distribution is given for selected ELAIS bands and colour-redshift diagrams are discussed. There is a high proportion of ultraluminous infrared galaxies (log(10) of 1-1000 mum luminosity L-ir > 12.22) in the ELAIS Catalogue (14 per cent of 15-mum galaxies with known z), many with Arp220-like SEDs. 10 per cent of the 15-mum sources are genuine optically blank fields to r' = 24: these must have very high infrared-to-optical ratios and probably have z > 0.6, so are high-luminosity dusty starbursts or Type 2 AGN. Nine hyperluminous infrared galaxies (L-ir > 13.22) and nine extremely red objects (EROs) (r - K > 6) are found in the survey. The latter are interpreted as ultraluminous dusty infrared galaxies at z similar to 1. The large numbers of ultraluminous galaxies imply very strong evolution in the star formation rate between z = 0 and 1. There is also a surprisingly large population of luminous (L-ir > 11.5), cool (cirrus-type SEDs) galaxies, with L-ir L-opt > 0, implying A(V) > 1."

Our observations in the R band cover the temporal range from 4.2 hr to 64 days after the high-energy event. We also present the results of multicolor imaging extending to the K band on three epochs. The light curve of the R-band afterglow the first week after the burst is similar to the light curve for long-duration gamma-ray bursts (GRBs), i.e., a broken power law with a late time slope of alpha approximate to 2.0 (F-nu proportional to t(-alpha)). Furthermore, the spectral energy distribution (SED) has a power-law (F-nu proportional to nu(-beta)) shape with slope beta approximate to 1.0. However, the decay slope at t < 1 day is shallow, consistent with zero. This is in qualitative agreement with the prediction that XRFs are off-axis classical GRBs. After the first week there is a strong bump in the light curve, which peaks at around 16 days. The SED after the peak becomes significantly redder. We discuss the possible interpretations of this bump and conclude that an underlying supernova is the most likely explanation since no other model appears consistent with the evolution of the SED. Finally, we present deep spectroscopy of the burst both in the afterglow and in the bump phase. A firm upper limit of z = 2.3 is placed on the redshift of XRF 030723 from the lack of Ly alpha forest lines in the spectrum of the afterglow. The lack of significant absorption and emission lines in either of the two spectra excludes a spectroscopic redshift determination."

Both objects have been reported to show ""anomalous positions"" in the HR diagram in the sense that they appear below the main sequence. A significant result of this work is that both stars arc metal-deficient. The Hipparcos distance of HD 34282 is very uncertain and the current study places the star at the expected evolutionary position in the HR diagram, i.e. as a PMS star. The distance for HD 141569 found in this work matches the Hipparcos distance, and the problem of its anomalous position is solved as a result of the low metallicity of the object: using the right metallicity tracks, the star is in the PMS region. The SEDs are constructed using data covering ultraviolet to millimetre wavelengths. Physical, non-parametric models, have been applied in order to extract some properties of the disks surrounding the stars. The disk around HD 34282 is accreting actively, it is massive and presents large grains in the mid-plane and small grains in the surface. HD 141569 has a very low mass disk, which is in an intermediate stage towards a debris-type disk."

A cluster of very red Cubewanos is firmly identified in orbits of low inclination and eccentricity beyond 40 AU from the Sun. Further correlations between surface colours and dynamical parameters ( inclination and perihelion distance) are suggested for Cubewanos and scattered disk objects, but lack complete confidence for their reality. Plutinos and Centaurs do not show any clear correlation between surface colours and orbital parameters. We present in this paper 12 spectra obtained in the visible region and nine of them for which we obtained also near infrared spectra up to 2.4 microns. A few other objects have been observed, but the data are still under reduction and analysis. The principal reported results obtained are: (i) a wide range of visible slopes; (ii) evidence for surface variations on 2001 PT13; and (iii) possible detection of few percent of water ice ( 1999 TC36, 2000 EB173, 1999 DE9\, 2001 PT13, 2000 QC(243), 1998 SG(35))."

Usually the livestock is not confined, so it is impossible to assess the amount of food each animal will eat. Therefore it makes no sense to design diets verifying the nutritional requirements exactly. It is more valuable to allow for constraint violations, i.e., fuzzy constraints which in turn may lead to cheaper diets. Under this scenario the problem is modelled as a fuzzy linear programming (FLP) one and then solved by using a decision support systems (DSS) named SACRA (a Spanish acronym for support system for the construction of cattle diets) that the authors have specifically developed for this problem. SACRA is based on PROBO, an already experimented DSS also developed by the authors, and it is highly friendship, interactive and does not require any knowledge about FLP. The tests carried out with SACRA have shown a high level of satisfaction from the side of the decision makers. (C) 2003 Elsevier B.V. All rights reserved."

We have monitored its host galaxy from 1-100 days after the burst. In spite of the high extinction to the source and the bright host, a significant increase and subsequent decrease has been detected in the apparent brightness of the host, peaking between 10 and 33 days after the GRB. The only convincing explanation is a supernova (SN) associated with the XRF, SN20031w. This is the earliest time at which a SN signal is clearly discernible in a GRB/XRF (apart from SN1998bw). SN20031w is extremely luminous with a broad peak and can be approximately represented by the lightcurve of SN1998bw brightened by similar to0.55 mag, implying a hypernova, as observed in most GRB-SNe. The XRF-SN association firmly links XRFs with the deaths of massive stars and further strengthens their connection with GRBs. The fact that SNe are also associated with XRFs implies that Swift may detect a significant population of intermediate redshift SNe very soon after the SN explosions, a sample ideally suited for detailed studies of early SN physics."

The concentration on a few selected sites gives better consistency and accuracy than collecting smaller amounts from a larger number of sites. 23 frequencies were detected with a high statistical significance. 6 of these are new. The 17 frequencies found in common with the 1992-1995 data are the modes with highest amplitudes. This indicates that the pulsation spectrum of FG Vir is relatively stable over the ten-year period. Two frequencies have variable amplitudes and phases from year to year as well as during 2002. These were both found to be double modes with close frequencies. For the mode at 12.15 c/d this leads to an apparent modulation with a time scale of similar to129 d. The close frequencies at 12.15 c/d are composed of a radial and a nonradial mode, suggesting a similarity with the Blazhko Effect seen in RR Lyrae stars."

VET spectra of the afterglow show damped Lyalpha (DLA) absorption and low- and high-ionization lines at a redshift z = 3.3718 +/- 0.0005. The inferred neutral hydrogen column density, log N(H I) = 21.90 +/- 0.07, is larger than any (GRB- or QSO-) DLA H I column density inferred directly from Lyalpha in absorption, From the afterglow photometry, we derive a conservative upper limit to the host-galaxy extinction: A(V) < 0.5 mag. The iron abundance is [Fe/H] = -1.47 &PLUSMN; 0.11, while the rnetallicity of the gas as measured from sulphur is [S/H] = -1.26 &PLUSMN; 0.20. We derive an upper limit on the H-2 molecular fraction of 2N(H-2)/(2N(H-2) + N(H I)) &LSIM; 10(-6). In the Ly&alpha; trough, a Ly&alpha; emission line is detected, which corresponds to a star-formation rate (not corrected for dust extinction) of roughly I M. yr(-1). All these results are consistent with the host galaxy of GRB 030323 consisting of a low metallicity gas with a low dust content. We detect fine-structure lines of silicon, Si II*, which have never been clearly detected in QSO-DLAs; this Suggests that these lines are produced in the vicinity of the GRB explosion site. Under the assumption that these fine-structure levels are Populated by particle collisions, we estimate the H I volume density to be n(H I) = 10(2)-10(4) cm(-3). HST/ACS imaging 4 months after the burst shows an extended AB(F606W) = 28.0 &PLUSMN; 0.3 mag object at a distance of 0.&DPRIME;14 (1 kpc) from the early afterglow location, which presumably is the host galaxy of GRB 030323."

A. niger and its exudates stimulated the germination and hyphal outgrowth of G. mosseae and Gi. rosea spores and AM colonization of roots by these and native fungi in an unsterilized soil. In contrast, T. harzianum and its exudates had no effects, and P. restrictum and its exudates had no effects on spore germination or hyphal outgrowth from spores of either G. mosseae or colonization by the native AM endophytes in an unsterilized soil. Effect of A. niger were dependent on the concentration of exudates and varied according to the AM endophyte. For example, the application of 1-2.5 mul/ml of exudates of A. niger increased the outgrowth of hyphae from spores of G. mosseae, but for Gi. rosea increases only occurred in the range 1-10 mul/ml. On the other hand, the colonization of plants by Gi. rosea increased with the application of 10 ml/pot of exudates of A. niger, but the colonization of soybean by G. mosseae or by native AM endophytes increased in the presence of 20 mul/pot of exudates. The similarity in trends observed in the effects of the saprobe fungi or their exudates on spore germination and hyphal length and effects on AM colonization of plants and number of propagules of AM fungi suggest that the effects of saprobe fungi are largely due to effects on the extraradical phase of the AM fungi."

UGC 813/6 are only the second known example of head-on spiral-spiral collisions, the first example being the UGC 12914/5 pair. Strong CO emission is present in the bridge between UGC 813 and 816, unassociated with stellar emission, just as in UGC 12914/5. The CO emission from the UGC 813/6 bridge, not counting the emission from the galaxies themselves, is at least that of the entire Milky Way. Collisions of gas-rich spirals are really collisions between the interstellar media (ISMs) of the galaxies. We show that collisions between molecular clouds bring H-2 into the bridge region. Although the dense clouds are ionized by the collisions, they cool and recombine very quickly and become molecular again even before the galactic disks separate. Because the clouds acquire an intermediate velocity post-collision, they are left in the bridge between the separating galaxies. The star formation efficiency appears low in the molecular clouds in the bridges. We speculate that the pre-stellar cores in the molecular clouds may expand during the cloud collisions, thus retarding future star formation. Because the ISM-ISM collisions discussed here require a very small impact parameter, they are rare among field spirals. In clusters, however, these collisions should be an important means of ejecting enriched gas from the inner parts of spirals."

The strains of T. pseudokoningii did not affect dry matter and percentage of root length colonization of soybean inoculated with G. mosseae, except T. pseudokoningii 2212, which inhibited both parameters. However, all T. pseudokoningii strains decreased the shoot dry matter and the percentage of AM root length colonization of soybean inoculated with Gi. rosea. The saprotrophic fungi tested seem to affect AM colonization of root by effects on the presymbiotic phase of the AM fungi.

Our infrared imaging observations are obtained with the 3.5 m Calar Alto telescope and the AO system ALFA. With two epoch observations which were separated by about one year, we found two co-moving companion candidates, one close to HD 77407 and one close to GJ 577. For the companion candidate near GJ 577, we obtained an optical spectrum showing spectral type M 4.5; this candidate is a bound low-mass stellar companion confirmed by both proper motion and spectroscopy. We estimate the masses for HD 77407 B and GJ 577 B to be similar to0.3 to 0.5 M-. and similar to0.16 to 0.2 M-., respectively. Compared to Siess et al. (2000) models, each of the two pairs appears co-eval with HD 77407 A, B being 10 to 40 Myrs and GJ 577 A, B being greater than or equal to 100 Myrs old. We also took multi-epoch high-resolution spectra of HD 77407 to search for sub-stellar companions, but did not find any with 3 M-Jup as upper mass (m sin i) limit (for up to 4 year orbit s); however, we detected a long-term radial velocity trend in HD 77407 A, consistent with a similar to0.3 M-. companion at similar to50 AU separation, i.e. the one detected by the imaging.

More than 60% of the stars present line profile variations which can be interpreted as due to pulsation related to gamma Doradus stars. For all stars we also derived the projected rotation velocity (up to more than 200 km s(-1)). The amplitude ratios 2K/Deltam for the main HIPPARCOS frequency are in the range 35-96 km s(-1) mag(-1). About 50% of the candidates are possible members of binary systems, with 20 stars being confirmed gamma Doradus. At least 6 stars present composite spectra, and in all but one case (for which only one spectrum could be obtained), the narrow component shows line profile variations, pointing towards an uncomfortable situation if this narrow component originates from a shell surrounding the star. This paper is the first of a series concerning mode identification using both photometric and spectroscopic methods for the confirmed gamma Doradus stars of the present sample."

Our main goal is to determine whether the stars that live in the innermost ( 100 pc scale) regions of these galaxies are in some way related to the emission-line properties, which would imply a link between the stellar population and the ionization mechanism. High signal-to-noise ratio, ground-based long-slit spectra in the 3500-5500 Angstrom interval were collected for 60 galaxies: 51 LINERs and LINER/H II transition objects, two starburst galaxies, and seven nonactive galaxies. In this paper, the first of a series, we ( 1) describe the sample; ( 2) present the nuclear spectra; ( 3) characterize the stellar populations of LLAGNs by means of an empirical comparison with normal galaxies; ( 4) measure a set of spectral indices, including several absorption-line equivalent widths and colors indicative of stellar populations; and ( 5) correlate the stellar indices with emission-line ratios that may distinguish between possible excitation sources for the gas. Our main findings are as follows: ( 1) Few LLAGNs have a detectable young (less than or similar to10(7) yr) starburst component, indicating that very massive stars do not contribute significantly to the optical continuum. In particular, no features due to Wolf-Rayet stars were convincingly detected. (2) High-order Balmer absorption lines of H I (HOBLs), on the other hand, are detected in similar to40% of LLAGNs. These features, which are strongest in 10(8) - 10(9) yr intermediate-age stellar populations, are accompanied by diluted metal absorption lines and bluer colors than other objects in the sample. ( 3) These intermediate-age populations are very common (similar to50%) in LLAGNs with relatively weak [O I] emission ([O I]/Halpha less than or equal to 0.25) but rare (similar to10%) in LLAGNs with stronger [O I]. This is intriguing since LLAGNs with weak [O I] have been previously hypothesized to be ""transition objects'' in which both an AGN and young stars contribute to the emission-line excitation. Massive stars, if present, are completely outshone by intermediate-age and old stars in the optical. This happens in at least a couple of objects where independent UV spectroscopy detects young starbursts not seen in the optical. (4) Objects with predominantly old stars span the whole range of [O I]/Halpha values, but (5) sources with significant young and/or intermediate-age populations are nearly all (similar to90%) weak [ O I] emitters. These new findings suggest a link between the stellar populations and the gas ionization mechanism. The strong -[ O I] objects are most likely true LLAGNs, with stellar processes being insignificant. However, the weak -[ O I] objects may comprise two populations, one where the ionization is dominated by stellar processes and another where it is governed by either an AGN or a more even mixture of stellar and AGN processes. Possible stellar sources for the ionization include weak starbursts, supernova remnants, and evolved poststarburst populations. These scenarios are examined and constrained by means of complementary observations and detailed modeling of the stellar populations in forthcoming communications."

Our goal is to search for spectroscopic signatures of young and intermediate-age stars and to investigate their relationship with the ionization mechanism in LLAGNs. The method used is based on the stellar population synthesis of the optical continuum of the innermost ( 20 - 100 pc) regions in these galaxies. For this purpose, we have collected high spatial resolution optical (2900 - 5700 Angstrom) STIS spectra of 28 nearby LLAGNs that are available in the Hubble Space Telescope archive. The analysis of these data is compared with a similar analysis also presented here for 51 ground-based spectra of LLAGNs. Our main findings are as follows: ( 1) No features due to Wolf-Rayet stars were convincingly detected in the STIS spectra. ( 2) Young stars contribute very little to the optical continuum in the ground-based aperture. However, the fraction of light provided by these stars is higher than 10% in most of the weak-[O I] ([O I]/Halpha less than or equal to 0.25) LLAGN STIS spectra. (3) Intermediate-age stars contribute significantly to the optical continuum of these nuclei. This population is more frequent in objects with weak than with strong [O I]. Weak -[O I] LLAGNs that have young stars stand out for their intermediate-age population. (4) Most of the strong -[O I] LLAGNs have predominantly old stellar population. A few of these objects also show a featureless continuum that contributes significantly to the optical continuum. These results suggest that young and intermediate-age stars do not play a significant role in the ionization of LLAGNs with strong [ O I]. However, the ionization in weak -[O I] LLAGNs with young and/or intermediate-age populations could be due to stellar processes. A comparison of the properties of these objects with Seyfert 2 galaxies that harbor a nuclear starburst suggests that weak -[O I] LLAGNs are the lower luminosity counterparts of the Seyfert 2 composite nuclei."

SVS 13 is a young close binary system whose components are separated by 65 AU in projection. Our high angular resolution observations reveal that only one of the components of the SVS 13 system (VLA 4B) is associated with detectable circumstellar dust emission. This result is in contrast with the well-known case of L1551 IRS 5, a binary system of two protostars separated by 45 AU, where each component is associated with a disk of dust. In both SVS 13 and in L1551 IRS 5 the emission apparently arises from compact accretion disks, smaller than those observed around single stars, but still massive enough to form planetary systems like the solar one. These observational results confirm that the formation of planets can occur in close binary systems, either in one or in both components of the system, depending on the specific angular momentum of the infalling material."

Gas velocity distributions are presented, together with a simple circular rotation model that allows us to determine the kinematical major axes. Stellar velocity distributions are also shown. The main result is that active and control galaxies seem to be equivalent in all kinematical aspects. For both subsamples, the departure from pure circular rotation in some galaxies can be explained by the presence of a bar and/or of a spiral arm. They also present the same kind of peculiarities, in particular, S-shape structures are quite common near the nuclear regions. They define very similar Tully-Fisher relations. Emission line ratios are Given for all the detected HII regions; the analysis of the [NIl]/Halpha metallicity indicator shows that active and non-active galaxies have indistinguishable disk metallicities. These results argue in favour of active and non-active isolated spiral galaxies having essentially the same properties, in agreement with our previous results based on the analysis of near infrared images. It appears now necessary to confirm these results on a larger sample."

Trypanosoma cruzi and Leishmania HMGRs are closely related in their catalytic domains to bacterial and eukaryotic enzymes described but lack an amino-terminal domain responsible for the attachment to the endoplasmic reticulum. In the present study, digitonin-titration experiments together with immunoelectron microscopy were used to establish the intracellular localization of HMGR in these pathogens. Results obtained with wild-type cells and transfectants overexpressing the enzyme established that HMGR in both T. cruzi and Leishmania major is localized primarily in the mitochondrion and that elimination of the mitochondrial targeting sequence in Leishmania leads to protein accumulation in the cytosolic compartment. Furthermore, T. cruzi HMGR is efficiently targeted to the mitochondrion in yeast cells. Thus, when the gene encoding T. cruzi HMGR was expressed in a hmg1 hmg2 mutant of Saccharomyces cerevisiae, the mevalonate auxotrophy of mutant cells was relieved, and immunoelectron analysis showed that the parasite enzyme exhibits a mitochondrial localization, suggesting a conservation between the targeting signals of both organisms."

Two detections have been obtained: the already known water maser emission in K3-35, and a new cluster of masers in IRAS 17347-3139. This low rate of detections is compatible with the short lifetime of water molecules in PNe (similar to100 yr). The water maser cluster at IRAS 17347-3139 are distributed on a ellipse of size similar or equal to0.""2 x 0.""1, spatially associated with compact 1.3 cm continuum emission ( simultaneously observed with the VLA). From archive VLA continuum data at 4.9, 8.4, and 14.9 GHz, a spectral index alpha = 0.76 +/- 0.03 (S-v proportional to v(alpha)) is derived for this radio source, which is consistent with either a partially optically thick ionized region or an ionized wind. However, the latter scenario can be ruled out by mass-loss considerations, thus indicating that this source is probably a young PN. The spatial distribution and the radial velocities of the water masers are suggestive of a rotating and expanding maser ring, tracing the innermost regions of a torus formed at the end of the asymptotic giant branch phase. Given that the 1.3 cm continuum emission peak is located near one of the tips of the major axis of the ellipse of masers, we speculate on a possible binary nature of IRAS 17347-3139, where the radio continuum emission could belong to one of the components and the water masers would be associated with a companion."

Spain has a population heavily exposed to various types of tobacco and alcoholic beverages but the role and impact of tobacco type and beverage type in oral carcinogenesis remain controversial. To estimate the independent and joint effects of tobacco smoking and alcohol drinking habits on the risk of developing oral cancer, we carried out a multicenter, hospital-based, case-control study in Spain. Data from 375 patients newly diagnosed with cancer of the oral cavity or oropharynx and 375 matched control subjects were analyzed using multivariate logistic regression procedures. All exposure characteristics of amount, duration and cessation of both tobacco smoking and alcohol drinking were strongly associated with cancer risk following a dose-dependent relationship. At equal intake or duration levels, black-tobacco smoking and drinking of spirits were both associated with a 2- to 4-fold increase in cancer risk compared to blond tobacco smoking or drinking of wine or beer, respectively. While ever exposure to smoking only or drinking only was associated with a moderate and nonsignificant increase in cancer risk, a history of simultaneous exposure to both habits was associated with a 13-fold increase that was compatible with a synergistic effect model (p-value for interaction: 0.008). Exposure to black tobacco smoking and/or drinking of spirits may account for up to 77% of oral cancer occurrence in Spain. Both black tobacco smoking and drinking of spirits place individuals at a very high risk of developing oral cancer.

The optimal RT activity was detected at a concentration of 5 mM Mg2+, pH 8 and between 28 and 37degreesC. Site-directed mutagenesis in the RT catalytic site proved that substitution of aspartic acid 313 for isoleucine (RTD313IL1Tc) practically abolishes the RT activity of the RTL1Tc protein. RT-polymerase chain reaction assays revealed that the RTL1Tc protein has the ability to use both homologous and heterologous RNA templates. Also, it is shown that the RTL1Tc protein is capable of synthesizing complementary DNA molecules by consecutive switching of the oligo molecule, which the protein uses as a template. This template switching may be involved in the retroelement integration process."

We discover a break in the afterglow light curve after 1.3 days, which implies an initial jet opening angle of about 9degrees. The jet origin of this break is supported by the fact that the spectral energy distribution is achromatic during the first 4 days. During later phases, GRB 011121 shows significant excess emission above the flux predicted by a power law, which we interpret as additional light from an underlying supernova. In particular, the spectral energy distribution of the optical transient approximately 2 weeks after the burst is clearly not of power-law type but can be presented by a blackbody with a temperature of similar to6000 K. The deduced parameters for the decay slope and the spectral index favor a wind scenario, i.e., an outflow into a circumburst environment shaped by the stellar wind of a massive gamma-ray burst (GRB) progenitor. Because of its low redshift of z = 0: 36, GRB 011121 has been the best example for the GRB-supernova connection until GRB 030329 and provides compelling evidence for a circumburster wind region expected to exist if the progenitor was a massive star."

Recently, we have reported the first unambiguous detection of water maser emission in a planetary nebula, K 3-35 (Miranda et al. 2001). The water masers in K3-35 were detected at the center of the nebula, along the minor axis, at a radius of similar to85 AU and also at the surprisingly large distance of 5000 AU from the star, at the tips of the bipolar lobes. The existence of these water molecules is puzzling, and probably we are observing the very moment of transformation of a giant star into a planetary nebula. Miranda et al. (2001) also report the presence of polarization in the OH 1665 MHz masers, which are distributed towards the central star in a torus-like structure. Here we review the main results on this source."

The data consist of lambda3.6-cm continuum, ground and space-based imaging, and high and low-dispersion longslit spectra. The structure of the central region seems to be a distorted, ring of 20"" in diameter. The lack of [N-II] emission is conspicuous, as revealed by imaging and low dispersion spectra. Notably, the kinematics of the point-symmetric (PS) structures of NGC 6309 indicates the presence of lobes or cavities as those generally found in bipolar nebulae.

Photometric observations and pulsational frequency analysis	MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY		English	Article						techniques : photometric; stars : early-type; stars : individual : mu Eridani; stars : individual : nu Eridani; stars : oscillations; stars : variables : other	WHOLE-EARTH-TELESCOPE; MODE-IDENTIFICATION; OSCILLATIONS; AMPLITUDE; CAMPAIGN	"We undertook a multisite photometric campaign for the beta Cephei star nu Eridani. More than 600 h of differential photoelectric uvyV photometry were obtained with 11 telescopes during 148 clear nights. The frequency analysis of our measurements shows that the variability of nu Eri can be decomposed into 23 sinusoidal components, eight of which correspond to independent pulsation frequencies between 5 and 8 cd(-1). Some of these are arranged in multiplets, which suggests rotational m-mode splitting of non-radial pulsation modes as the cause. If so, the rotation period of the star must be between 30 and 60 d. One of the signals in the light curves of nu Eri has a very low frequency of 0.432 cd(-1). It can be a high-order combination frequency or, more likely, an independent pulsation mode. In the latter case, nu Eri would be both a beta Cephei star and a slowly pulsating B (SPB) star. The photometric amplitudes of the individual pulsation modes of nu Eri appear to have increased by about 20 per cent over the last 40 years. So have the amplitudes of the dominant combination frequencies of the star. Among the latter, we could only identify sum frequencies with certainty, not difference frequencies, which suggests that neither light-curve distortion in its simplest form nor resonant mode coupling is their single cause. One of our comparison stars, mu Eridani, turned out to be variable with a dominant time-scale of 1.62 d. We believe either that it is an SPB star just leaving its instability strip or that its variations are of rotational origin."

The broad-band UBVRIJHKs photometry is used to determine the global spectral energy distribution (SED) of the host galaxy. Comparison with that of known galaxy types shows that the host is similar to a moderately kreddened starburst galaxy with a young stellar population. The estimated internal extinction in the host is A(V) = 0.15 +/- 0.1 and the star-formation rate (SFR) from the UV continuum is 1.3 +/- 0.3 M-circle dot yr(-1) (not corrected for the effects of extinction). Other galaxy template spectra than starbursts failed to reproduce the observed SED. We also present VLT spectra leading to the detection of Halpha from the GRB host galaxy. A SFR of 2.8 +/- 0.7 M-circle dot yr(-1) is inferred from the Halpha line flux, and the presence of a young stellar population is supported by a large equivalent width. Images from HST/STIS show that the host has two separate knots, which could be two distinct star-forming regions."

To investigate these associations, we conducted a multicenter case-control study of cancer of the oral cavity and oropharynx in nine countries. Methods: We recruited 1670 case patients (1415 with cancer of the oral cavity and 255 with cancer of the oropharynx) and 1732 control subjects and obtained an interview, oral exfoliated cells, and blood from all participants and fresh biopsy specimens from case patients. HPV DNA was detected by polymerase chain reaction (PCR). Antibodies against HPV16 L1, E6, and E7 proteins in plasma were detected with enzyme-linked immunosorbent assays. Multivariable models were used for case-control and case-case comparisons. Results: HPV DNA was detected in biopsy specimens of 3.9% (95% confidence interval [CI] = 2.5% to 5.3%) of 766 cancers of the oral cavity with valid PCR results and 18.3% (95% CI = 12.0% to 24.7%) of 142 cancers of the oropharynx (oropharynx and tonsil combined) with valid PCR results. HPV DNA in cancer biopsy specimens was detected less frequently among tobacco smokers and paan chewers and more frequently among subjects who reported more than one sexual partner or who practiced oral sex. HPV16 DNA was found in 94.7% of HPV DNA-positive case patients. HPV DNA in exfoliated cells was not associated with cancer risk or with HPV DNA detection in biopsy specimens. Antibodies against HPV16 L1 were associated with risk for cancers of the oral cavity (odds ratio [OR] = 1.5, 95% CI = 1.1 to 2.1) and the oropharynx (OR = 3.5, 95% CI = 2.1 to 5.9). Antibodies against HPV16 E6 or E7 were also associated with risk for cancers of the oral cavity (OR = 2.9, 95% CI = 1.7 to 4.8) and the oropharynx (OR = 9.2. 95% CI = 4.8 to 17.7). Conclusions: HPV appears to play an etiologic role in many cancers of the oropharynx and possibly a small subgroup of cancers of the oral cavity. The most common HPV type in genital cancers (HPV16) was also the most common in these tumors. The mechanism of transmission of HPV to the oral cavity warrants further investigation."

One source has a collimated, jetlike outflow at a 2000 AU scale, while the other has a shell outflow at a 160 AU scale expanding in multiple directions with respect to a central compact radio continuum source. This result reveals that outflow collimation is not only a consequence of ambient conditions but is something intrinsic to the individual evolution of stars and brings to light the possibility of noncollimated outflows in the earliest stages of YSOs."

Spiked soil samples having different physico-chemical properties, and selected soil-derived matrices with diverse MBT adsorption capacity, characterized by their Freundlich equation K-f values, were used to verify the method applicability to a broad range of different soils. The spiking procedure was considered a crucial point to reproduce as closely as possible the solute - soil adsorption taking place in the natural environment. Ageing effects, where the compound could diffuse into inaccessible locations within the soil matrix in view of its great stability, were considered of particular concern. In spite of the heterogeneous physico-chemical properties of soils under study, recoveries were greater than 90%. Performance of the MASE procedure correlated highly with the adsorption capacity of soil-derived matrices: the lowest recoveries were for illite ( 67 - 73%), among the mineral surfaces, and for a humic acid ( 67 - 72%), among the organic fractions. Intra-assay variation for each type of sample soil range from 0.40 to 3.89% (RSD). Limits of detection and quantification were 0.047 and 0.15 mug g(-1), respectively.

Methods: Extracted human third molars had their crowns transversally sectioned either next to the occlusal DEJ or next to the pulp, to expose flat, superficial or deep dentin surfaces. The surfaces were bonded with: 1) three two-step, total-etch, self-priming adhesives (Single Bond, Prime&Bond NT, and Excite), 2) a two-step, self-etching primer (Clearfil SE Bond), and 3) a single-step, self-etching all-in-one adhesive (Etch & Prime 3.0) according to manufacturers' directions. Composite build-ups were constructed incrementally with Z250. After storage for 24 hours in water at 37degreesC, the teeth were sectioned to obtain several bonded beams of 1.0 mm(2) cross-sectional area. Each beam was tested in tension in an Instron machine at 0.5 mm/minute. Results were analyzed by two-way ANOVA and post-hoc multiple comparisons (P= 0.05). Bonded interfaces were also examined by TEM. Nanoleakage was examined using a silver-staining technique. Results: Single Bond, Prime&Bond NT and Clearfil SE Bond performed equally when were bonded to superficial dentin; the lowest value was obtained with Etch & Prime 3.0. On deep dentin, the highest bond strengths were attained with Clearfil SE Bond and Prime&Bond NT. The bond strengths of Prime&Bond NT and Excite were significantly higher to deep than to superficial dentin and the rest of the adhesives showed similar bond strength to both dentin depths. Nanoleakage was manifested to variable extent within all hybrid layers examined."

The burst occurred in a very faint (Rgreater than or similar to29.5) damped Lyalpha absorber (DLA) at a redshift of z=3.198+/-0.004. The derived column density of neutral hydrogen is log(N-Hi)=21.7+/-0.2, and the rest-frame reddening is constrained to be E(B-V)<0.065, i.e., A(V)<0.20 for standard extinction laws with R-V&AP;3. The resulting dust-to-gas ratio is less than 11% of that found in the Milky Way but consistent with the SMC and high-redshift QSO DLAs, indicating a low metallicity and/or a low dust-to-metal ratio in the burst environment. A gray extinction law (large R-V), produced through preferential destruction of small dust grains by the gamma-ray burst, could increase the derived A(V) and dust-to-gas ratio. The dimness of the afterglow is, however, fully accounted for by the high redshift: if GRB 020124 had been at z=1, it would have been approximately 1.8 mag brighter-in the range of typical bright afterglows."

Here we report the discovery of a dim optical afterglow (OA) that would not have been detected by many previous searches due to its faintess (R similar to 23). This OA was seen to decline following a power law decay with index alpha(R) = - 0.95 +/- 0.16. The spectral index beta(opt/NIR) yielded - 1.25 +/- 0.14. These values may be explained by a relativistic expansion of a fireball ( with p = 2.0) in the cooling regime. We also find evidence for inverse Compton scattering in X-rays.

Two giant and 10 dwarf/ H II galaxies, members of a group, are simultaneously undergoing a burst of star formation. Redshift measurements suggest that the group galaxies are in the process of falling into the cluster at very high speed. We explore two possible mechanisms that could have triggered the short-lived stellar burst that we are witnessing: the first, internal to the group itself, via tidal interactions among its members, the hypothesis favored by Sakai et al.; the second associated with the high-velocity infall of the group galaxies into the cluster intergalactic medium.

These compounds are potential inhibitors of the enzyme sterol 24-methyltransferase (24-SMT), which is a vital enzyme in the biosynthesis of ergosterol and related 24-alkyl sterols. Structure-activity studies were undertaken to understand the important features for activity against the enzyme, with the aim of increasing activity and selectivity. The compounds were evaluated for inhibition of recombinant Leishmania major 24-SMT and the effect of compounds on sterol composition and parasite proliferation. Essentially, compounds which showed good activity against the recombinant enzyme had a significant effect on the sterol composition and growth of parasites. The activity of compounds was found to be related to the basicity and stereochemical location of the nitrogen. Also, presence of an unprotected 3beta-OH seemed to be important for activity. However, some azasterols which were not good inhibitors of 24-SMT also showed antiproliferative activity, suggesting that there may be other modes of actions of these compounds."

Plant growth, macro and micronutrient assimilation, and specific absorption rate (SAR) were measured. Arbuscular mycorrhizal (AM) colonization and extraradical mycelium development were also examined. The high availability of N and P in the soil reduced the content of macro and micronutrients in AM plants. At the lowest P application (0.1 mM), the AM colonization increased nutrient acquisition at all N levels tested. However, the highest application of N and P to the soil reduced the uptake of N, P, K, Mn and Zn in AM compared to non-AM lettuce plants. These fertilizer levels were also inhibitory to AM-intra and extraradical colonization. In contrast to non-AM plants, AM colonization increased SAR values at the lowest N and P levels for nearly all the nutrients, and decreased the amount of nutrients absorbed per unit of root mass at the highest N and P levels applied. Results demonstrated some negative effects of high N and P application in soil on the acquisition of N, P, K, Fe, Mn and Zn for mycorrhizal plants. (C) 2003 Elsevier Ireland Ltd.

A drop of the velocity dispersions in the innermost +/-(1-3) arcsec is observed in four of them, and hinted at in the remaining galaxy (NGC 6814). The available HST images for our sample together with another nine galaxies with reported velocity dispersion drops are also used to investigate the presence of morphological inner structures at the scales of the kinematical drops. Evidence for disk-like shapes is found in 12 out of the 14 cases. The only exceptions are NGC 6814 and NGC 6951. Existing N-body simulations including stars, gas and star formation predict that such a drop is most probably due to a young stellar population born from dynamically cold gas accreted in a circumnuclear disk formed during an episode of central gas accretion driven by a bar. The equivalent widths of the calcium triplet lines for our 5 galaxies have been measured. Even if the profiles could be formally consistent with constant EW(CaT) values, they seem to indicate the presence of a local maximum in the regions corresponding spatially to the drops; if confirmed, this would imply the presence of a different stellar population, whose properties could help constrain the models."

We find that: (i) the best SED fit is obtained with a starburst template, (ii) the photometric redshift is consistent with the spectroscopic redshift, (iii) the colours of the host are inconsistent with an old stellar population, and (iv) the global extinction is constrained to be in the range A(V) = 0.12-0.61 mag. The derived global extinction agrees with the one reported for the afterglow (A(V) = 0.4-0.9 mag), suggesting a homogeneous distribution of the interstellar medium (ISM) in the host galaxy. These findings are supplemented by morphological information from Hubble Space Telescope (HST) imaging: the surface brightness profile is smooth, symmetric and compact with no underlying structures (like dust lanes, spiral arms or disks). A natural scenario which accounts of all the above results is a nuclear starburst that harbours a young population of stars from which the GRB originated."

The AA Tau light curve had been previously shown to vary with a 8.2 d period, exhibiting a roughly constant brightness level, interrupted by quasi-cyclic fading episodes, which we interpreted as recurrent eclipses of the central star by the warped inner edge of its accretion disk (Bouvier et al. 1999). Our observations show the system is dynamic and presents non-stationary variability both in the photometry and spectroscopy. The star exhibits strong emission lines that show substantial variety and variability in their profile shapes and fluxes. Emission lines such as Halpha and Hbeta show both infall and outflow signatures and are well reproduced by magnetospheric accretion models with moderate mass accretion rates (10(-8)- 10(-9) M-. yr(-1)) and high inclinations (i greater than or equal to 60degrees). The veiling shows variations that indicate the presence of 2 rotationally modulated hot spots corresponding to the two magnetosphere poles. It correlates well with the He i line flux, with B - V and the V excess flux. We have indications of a time delay between the main emission lines (Halpha, Hbeta and He I) and veiling, the lines formed farther away preceding the veiling changes. The time delay we measure is consistent with accreted material propagating downwards the accretion columns at free fall velocity from a distance of about 8 R-star. In addition, we report periodic radial velocity variations of the photospheric spectrum which might point to the existence of a 0.02 M-. object orbiting the star at a distance of 0.08 AU. During a few days, the eclipses disappeared, the variability of the system was strongly reduced and the line fluxes and veiling severely depressed. We argue that this episode of quiescence corresponds to the temporary disruption of the magnetic configuration at the disk inner edge. The smooth radial velocity variations of inflow and outflow diagnostics in the Halpha profile yield further evidence for large scale variations of the magnetic configuration on a timescale of a month. These results may provide the first clear evidence for large scale instabilities developping in T Tauri magnetospheres as the magnetic field lines are twisted by differential rotation between the star and the inner disk. The interaction between the inner accretion disk and the stellar magnetosphere thus appears to be a highly dynamical and time dependent process."

This cassette formal test was evaluated first in blind with a panel of 393 coded serum samples. The Chagas Stat-Pak identified 197 infected (98.5% sensitivity) and 183 non-infected individuals (94.8% specificity). A second evaluation was performed with 352 sera from four Latin America countries tested independently in each Country, showing a sensitivity of 100% and specificity of 98.6%. A third set of tests comparing sera with plasma and eluates from filter paper as well as serum preserved in 50% glycerol did show identical results as those obtained with serum. This rapid test (15 min) uses one device per sample, does not require refrigeration nor a laboratory structure or specialized skills to be performed, accepts different types of samples and may be stored for long periods of time for result checking and documentation. These attributes together with the high sensitivity and specificity demonstrated herein, make this test a suitable tool for field studies, small laboratories and emergencies at blood banks in the countryside of endemic areas.

We present contour maps, surface brightness and color profiles, and color maps of the sample galaxies. The morphology of the BCDs in the near-infrared (NIR) has been found to be basically the same as in the optical. The inner regions of these systems are dominated by the starburst component. At low surface brightness levels the emission is due to the underlying host galaxy; the latter is characterized by red, radially constant colors and isophotes well fitted by ellipses. We derive accurate optical-NIR host galaxy colors for eight of the sample galaxies; these colors are typical of an evolved stellar population. Interestingly, optical-NIR color maps reveal the presence of a complex, large-scale absorption pattern in three of the sample galaxies. We study the applicability of the Sersic law to describe the surface brightness profiles of the underlying host galaxy and find that, because of the limited surface brightness interval over which the fit can be made, the derived Sersic parameters are very sensitive to the selected radial interval and to errors in the sky subtraction. Fitting an exponential model gives generally more stable results and can provide a useful tool to quantify the structural properties of the host galaxy and compare them with those of other dwarf classes, as well as with those of star-forming dwarfs at higher redshifts."

From this study, the star is definitively classified as an evolved delta Sct-type variable with solar metal abundances. This conclusion is also supported by the detected multiperiodic pulsational behaviour and the observed variation of the m(1) index over the pulsation cycle. This variation is slightly reversed relative to the V light curve, in very good agreement with the m(1) variation expected from the photometric calibrations. Besides the main frequency f(1)=5.3745 cd(-1) and its first harmonic 2f(1), a secondary peak is found at f(2)=5.8332 cd(-1) (f(1)/f(2)=0.92) with f(1) identified as a radial mode and f(2) as non-radial. Whereas no significant variations are found in the amplitude of f(1) from season to season, the amplitude of f(2) changes strongly. Moreover, the main period has remained constant since 1990, within the observational uncertainties. Additional secondary frequencies may also be excited in this variable."

Phylogenetically, Ensifer and Sinorhizobium form a single group in the 16S rDNA dendrogram of the alpha-Proteobacteria, as well as in an analysis of partial recA gene sequences. They may therefore be regarded as a single genus. Because Sinorhizobium was proposed in 1988, according to the Bacteriological Code (1990 Revision) the older name, Ensifer, has priority. However, there are several reasons why a change from Sinorhizobium to Ensifer may not be the best solution and making an exception to Rule 38 may be more appropriate.

For three regions of the sample (SBS 0335 - 052, I Zw 18, and H29) we present tailored photoionization models based on improved calculations with respect to previous models. In particular, we use the photoionization models to study quantitatively the effect of collisional excitation of Balmer lines on the determination of the helium abundance (Y) in the individual regions. This effect is twofold: first, the intensities of the Balmer lines are enhanced with respect to the pure recombination value, mimicking a higher hydrogen abundance; second, the observed reddening is larger than the true extinction, as a result of the differential effect of collisions on different Balmer lines. In addition to these effects, our analysis takes into account the following features of H II regions: ( 1) the temperature structure, ( 2) the density structure, ( 3) the presence of neutral helium, ( 4) the collisional excitation of the He I lines, ( 5) the underlying absorption of the He I lines, and ( 6) the optical thickness of the He I lines. The object that shows the highest increase in Y after the inclusion of collisional effects in the analysis is SBS 0335 - 052, whose helium abundance has been revised by DeltaY = +0.0107. The revised Y-values for the five objects in our sample yield an increase of + 0.0035 in Y-P, giving Y-P = 0.2391 +/- 0.0020."

These soils constitute excellent models to study both natural and man-induced VA mycorrhizal effect over plant nutrition and soil ecology sustainability. This paper studies the effect of Glomus etunicatum inoculation of wheat in a natural volcanic soil fertilized with soluble P or with partially acidulated-rock phosphate (pa-RP) at two rates (17 and 86 kg P ha(-1)); yield, plant phosphorus acquisition, and mycorrhizal colonized root length, are measured. The influence of these treatments on mycorrhizal mycelium and spore production as well as on soil phosphatase (P-ase) activity was also determined. The inoculation of G. etunicatum, locally isolated, increased significantly the extent of P plant acquisition, spore number, length of extraradical mycelium, and P-ase activity when compared with indigenous arbuscular mycorrhizal (AM) fungi fertilized with pa-RP, at the level of 86 kg ha(-1). In concordance with these results, the remaining available P in the experimental soil without inoculation was depressed. A negative impact of soluble P application in G. etunicatum inoculated soil was noted in the P-ase activity, and also in the effectiveness of the applied inoculum in relation to P plant uptake. In soil AM inoculated and fertilized with pa-RP (86 kg ha(-1)), the enhancement of P-ase activity was related to high mycelium development and spore formation. P plant acquisition in G. etunicatunt inoculated plants ranged from 4.96 to 11.57 mg per pot when 86 kg ha(-1) of pa-RP is applied compared with the same amount of soluble P Surprisingly, adding pa-RP does not improve the amount of colonized root length. Fungal root AM colonization and AM propagules (mycelium and spores) were not depressed at higher soluble P supply, but the activity of G. etunicatum measured as P plant uptake was strongly affected. The inoculation with G. etunicatum enhances spore production, particularly at the lower soluble P and at the highest pa-RP levels. A close relationship (r = 0.938) between AM spores and P-ase activity was found. Only in pa-RP treatments the G. etunicatum inoculation reduced the external P wheat requirements. The improvement of P-ase activity by G. etunicatum inoculation, as a biological factor involved in P-cycling in soil, may be an important mechanism related to plant P acquisition.

Histochemical determination of succinate dehydrogenase (SDH) and alkaline phosphatase (ALP) activities which indicate active fungal metabolism was carried out at two phosphorus (P) levels. The presence of B.t. increased extra- and intraradical colonization [measured as frequency (%F), intensity (%I) and percentage of arbuscules (%A)] for both arbuscular mycorrhizal fungi (AMF) rather than plant growth or nutrition regardless P level. Under the lowest level of P fertilization, B.t. enhanced to a similar extent the extra- and intraradical development of both endophytes, but the proportion of fungal tissue showing SDH or ALP was increased in G. intraradices-colonized plants. [SDH: 458% (M) and 512% (A); ALP: 358% (M) and 300% (A)]. P supply decreased G. intraradices colonization to a higher extent than G. mosseae. Nevertheless, the totality of G. intraradices structures developed in P-amended medium showed intraradical o extraradical activity, while in G. mosseae-colonized roots, SDH and ALP activities highly decreased relative to fungal tissue determined by TB staining as affected by P. Our results show that bacterial inoculation compensates the negative effect of P on the intraradical fungal growth and vitality. P amendment reduced in a higher extent G. intraradices infection intensity (non-vital and vital staining) and G. mosseae activity (ALP staining). Thus, big differences in the proportion of SDH-active infection showing ALP activity in mycelium developed by each endophyte were noted at the highest P level. Physiological plant parameters such as photosynthetic activity did not explain specific changes on each arbuscular-mycorrhizal fungus as affected by P or B.t. inoculation. The increased extraradical mycelium development and metabolic fungal activity as a result of B.t. inoculation positively affected N and P plant content and photosynthetic rate in G. intraradices-colonized plants under the lowest P conditions. In general, the increased metabolically active fungal biomass in co-inoculated plants was irrespective of P level and was not related to the P plant uptake from the inert soil-less substrate. These results show the bacterial effect increasing the physiological and metabolic status of AM endophytes, which not only confirms but also extends previous findings on arbuscular mycorrhizae-bacteria interactions. The present study emphasizes the ecological and practical importance of rhizosphere free-living bacteria as mycorrhizae-helper microorganisms. (C) 2003 Elsevier Science Ltd. All rights reserved."

In the context of currently available models for changes in the polarization of GRBs, a homogeneous jet with an early break time of t(b) approximate to 1 day provides a good explanation of our data.

The aim of this paper was to deepen the study of the spatial pattern of pectin distribution in the aperture of Oenothera hookeri.velans ster/+ster fertile pollen. We used ""in situ"" immunocytochemical techniques at electron microscopy, involving monoclonal antibodies JIM5 and JIM7 directed against pectin epitopes in fertile pollen grains of Oenothera hookeri.velans ster/+ster. The same region was also analyzed by classical cytochemistry for polysaccharide detection. Immunogold labelling at the JIM7 epitope showed only in mature pollen labelling mainly located at the intine endo-aperture region. Cytoplasmic structures near the plasma membrane of the vegetative cell showed no labelling gold grains. In the same pollen stage the labelling at the JIM5 epitope was mostly confined to a layer located in the limit between the endexine and the ektexine at the level of the border of the oncus. Some tubuli at the base of the ektexine showed also an accumulation of gold particles. No JIM5 label was demonstrated in the aperture chamber and either in any cytoplasmic structure of the pollen grains. The immunocytochemical technique, when compared with the traditional methods for non- cellulose polysaccharide cytochemistry is fare more sensitive and allows the univocal determination of temporal and spatial location of pectins recognized by the JIM7 and JIM5 MAbs."

This evidence was originally based on the probable association of one unusual GRB with a supernova(1), but now includes the association of GRBs with regions of massive star formation in distant galaxies(2,3), the appearance of supernova-like 'bumps' in the optical afterglow light curves of several bursts(4-6) and lines of freshly synthesized elements in the spectra of a few X-ray afterglows(7). These observations support, but do not yet conclusively demonstrate, the idea that long-duration GRBs are associated with the deaths of massive stars, presumably arising from core collapse. Here we report evidence that a very energetic supernova (a hypernova) was temporally and spatially coincident with a GRB at redshift z=0.1685. The timing of the supernova indicates that it exploded within a few days of the GRB, strongly suggesting that core-collapse events can give rise to GRBs, thereby favouring the 'collapsar' model(8,9)."

Ground-based optical observations, performed with 8 different telescopes, started about 1 day after the high-energy prompt event and spanned a period of similar to10 days; the addition of archival HST data extended the coverage up to similar to150 days after the GRB. We report the first detection of the afterglow in NIR bands. The detection of Balmer and oxygen emission lines in the optical spectrum of the host galaxy indicates that the GRB is located at redshift z = 0.691. Fe II and Mg II absorption systems are detected at z = 0.691 and at z = 0.472 in the afterglow optical spectrum. The latter system is likely caused by absorbing clouds in the galaxy complex located similar to2"" southwest of the GRB020405 host. Hence, for the first time, the galaxy responsible for an intervening absorption line system in the spectrum of a GRB afterglow is spectroscopically identified. Optical and NIR photometry of the afterglow indicates that, between 1 and 10 days after the GRB, the decay in all bands is consistent with a single power law of index alpha = 1.54 +/- 0.06. The late-epoch VLT J-band and HST optical points lie above the extrapolation of this power law, so that a plateau ( or ""bump"") is apparent in the VRIJ light curves at 10-20 days after the GRB. The light curves at epochs later than day similar to20 after the GRB are consistent with a power-law decay with index alpha' = 1.85 +/- 0.15. While other authors have proposed to reproduce the bump with the template of the supernova ( SN) 1998bw, considered the prototypical ""hypernova"", we suggest that it can also be modeled with a SN having the same temporal profile as the other proposed hypernova SN2002ap, but 1.3 mag brighter at peak, and located at the GRB redshift. Alternatively, a shock re-energization may be responsible for the rebrightening. A single polarimetric R-band measurement shows that the afterglow is polarized, with P = 1.5 +/- 0.4% and polarization angle theta = 172degrees +/- 8degrees. Broad-band optical-NIR spectral flux distributions show, in the first days after the GRB, a change of slope across the J band which we interpret as due to the presence of the electron cooling frequency v(c). The analysis of the multiwavelength spectrum within the standard fireball model suggests that a population of relativistic electrons with index p similar to 2.7 produces the optical-NIR emission via synchrotron radiation in an adiabatically expanding blastwave, with negligible host galaxy extinction, and the X-rays via Inverse Compton scattering off lower-frequency afterglow photons."

In Chungara, the and period was shorter and occurred during the late 19th and early 20th centuries, while in Miscanti, it occurred earlier and ended at the beginning of the 20th century. In El Peinado, conditions were wetter during the 17-19th centuries and the and period occurred prior to the 17th century. Other records from the region show abrupt paleohydrological and paleoclimatic changes synchronous with the termination of the Little Ice Age. Despite local differences and dating uncertainties, the Little Ice Age stands out as a significant though complex climatic event in the Andean Altiplano. The discrepancies between the northern and southern Altiplano records during the last few centuries may reflect contrasting responses to external forcing in two areas with different climatic regimes.

The chromitites and hosting dunites were firstly affected by a regional serpentinization event, a subsequent episode of hydrothermal alteration (chloritization mainly) and, finally, these already altered bodies were crosscut by thin calcite-dominated veins. Analysed serpentines from serpentinized chromitites and dunites present very similar isotopic compositions (delta(18)O= + 4.7 parts per thousand to + 6.3 parts per thousand and deltaD = - 67 parts per thousand to - 60 parts per thousand), suggesting that the serpentinization process took place at moderate temperatures, in an oceanic environment. Serpentine formation by interaction with ocean water is also supported by the isotopic composition of chlorite and calcite. These results suggest that the serpentinization, chloritization and fracture filling processes of the Mayari-Baracoa Ophiolite Belt took place in a subocean floor scenario and, thus, that the Mayari-Baracoa serpentines represent a good example of serpentine formed during interaction with seawater. The oceanic origin of the serpentines from serpentinized chromitites and dunites from the MBOB indicate that the serpentinization of the mantle sequence occurred pre-thrusting (pre-emplacement in age).

We carried out a photometric search for Lyalpha emitters on scales less than or similar to 10 h(-1) Mpc in the fields of a sample of 47 z approximate to 3 known QSOs. Wide and narrowband filter color-magnitude diagrams were generated for each of the 6'.6 x 6'.6 fields. A total of 13 nonresolved objects with a significant color excess were detected as QSO candidates at a redshift similar to that of the target. All the candidates are significantly fainter than the reference QSOs, with only two of them within 2 mag of the central object. Follow-up spectroscopic observations have shown that five, i.e., about 40% of the candidates, are QSOs at the same redshift of the target; four are QSOs at different z ( two of them probably being a lensed pair at z = 1.47); two candidates are unresolved H II galaxies at z similar to 0.3; and one unclassified and one candidate turned out to be a CCD flaw. These data indicate that at least 10% of the QSOs at z similar to 3 do have companions. We have also detected a number of resolved, rather bright Lyalpha emitter candidates. Most likely, a large fraction of them might be bright galaxies with [O II] emission, at z approximate to 0.3. The fainter population of our candidates corresponds to the current expectations. Thus, there are no strong indications for the existence of an overdensity of Lyalpha galaxies brighter than m approximate to 25 around QSOs at z approximate to 3."

A common property of these three hosts is their extreme faintness. The location at which GRBs occur with respect to their host galaxies and surrounding environments are robust indicators of the nature of GRB progenitors. The bursts studied here are among the four most extreme outliers, in terms of relative distance from the host center, in the recent comprehensive study of Bloom et al. (2002). We obtain a revised and much higher probability that the galaxies identified as hosts indeed are related to the GRBs (P(n(chance))=0.69, following Bloom et al. 2002), thereby strengthening the conclusion that GRBs are preferentially located in star-forming regions in their hosts. Apart from being faint, the three hosts consist of multiple structures, indicative of merging and active star-formation.

We present an analysis of carbon monoxide spectra observed at SEST. A detailed picture of the nature of the post-perihelion outgassing at large heliocentric distances is shown. The data starts at 2.9 AU, with active water sublimation, and stretch outside 10 AU, where CO-driven activity is still detected. The activity is studied using a coma model which separates the outgassing into two different sources, one insolation-dependent source, peaking at the subsolar point, and one isotropically outgassing source. Gas velocities and production rates of the two sources are derived for two different cases. In the first case the isotropic source is assumed to be inside the nucleus, and in the second case this source is assumed to be CO-rich material in the coma. Under both assumptions, the results indicate that the two component sources evolve independently. At heliocentric distances around 3 AU, acceleration of the CO molecules in the innermost region of the coma is required for the model to fit the observations. This acceleration must occur at a slower rate than that predicted by hydrodynamic simulations. From 6 to 10 AU, the derived parameters appear remarkably constant. The nuclear outgassing velocity is generally unchanged with heliocentric distance during this wide interval. Observations of molecules other than CO are included in the SEST dataset, and a comparison is made to the modelling results. HCN and CH3OH show signs of being produced in the same way as the CO up to a heliocentric distance of 6 AU."

These observations provide a detailed characterization of the CO (1-0) vibrational band, clearly separating for the first time individual CO lines (P10 to P19 lines of (CO)-C-13). They indicate that the CO/N-2 mixing ratio in Titan's troposphere is 32+/-10 ppm. Comparison with photochemical models indicates that CO is not in a steady state in Titan's atmosphere. The observations confirm that Titan's 5-mum continuum geometric albedo is similar to0.06, and further indicates a similar to20% albedo decrease over 4.98-5.07 mum. Nonzero flux is detected at the 0.01 geometric albedo level in the saturated core of the (CO)-C-12 (1-0) band, at 4.75-4.85 mum, providing evidence for backscattering on the stratospheric haze. Finally, emission lines are detected at 4.75-4.835 mum, coinciding in position with lines from the CO(1-0) and/or CO(2-1) bands. Matching them by thermal emission would require Titan's stratosphere to be much warmer (by similar to 25 K at 0.1 mbar) than indicated by the methane 7.7-mum emission and the Voyager radio-occultation. We show instead that a nonthermal mechanism, namely solar-excited fluorescence, is a more plausible source for these emissions. Improved observations and laboratory measurements on the vibrational-translational relaxation of CO are needed for further interpretation of these emissions in terms of a CO stratospheric mixing ratio.

Tobacco and alcohol have been identified as the two major risk factors for oral cancer in most western populations. Other risk factors include diets low in fruits and vegetables, but the impact of dietary habits on the risk of these cancers has never been assessed in Spain. The objective of this study was to elucidate the role of dietary habits in oral and oropharyngeal cancer, a multicentric case-control study was conducted in three areas of Spain (Barcelona, Granada and Sevilla) between 1996 and 1999. Cases were 375 patients (71 women), with incident, histologically confirmed cancer of the oral cavity or oropharynx, and controls were 375 subjects (71 women) admitted to hospitals for conditions unrelated to smoking or alcohol drinking. Data were analysed using multivariate logistic regression procedures. After allowance for education, tobacco and alcohol use, a significant inverse association with the risk of oral and oropharyngeal cancer was found for total consumption of total green vegetables (OR 0.54, 95% Cl = 0.34-0.87) and total fruit (OR 0.52, 95% CI = 0.34-0.79) with significant trends in risk. We found that the protective effect of each of these food items was consistently larger among current smokers and among heavy alcohol drinkers, following a multiplicative effect model. In conclusion, this study provides further support to the beneficial effect of high intake of vegetables and fruits on the risk of developing cancers of the oral cavity and oropharynx in Spain, particularly among current smokers and heavy alcohol drinkers.

These observations represent the most exhaustive photometry given to date of any GRB host galaxy. A grid of spectral templates have been fitted to the Spectral Energy Distribution (SED) of the host. The derived photometric redshift is z = 0.842(-0.042)(+0.014), which is in excellent agreement with the spectroscopic redshift (z = 0.8463 +/- 0.0002) proposed by Piro et al. (2002) based on a single emission line. Furthermore, we have determined the photometric redshift of all the galaxies in an area of 6' x 6' around the host galaxy, in order to check for their overdensity in the environment of the host. We find that the GRB 000210 host galaxy is a subluminous galaxy (L similar to 0.5 +/- 0.2 L*), with no companions above our detection threshold of 0.18 +/- 0.06 L*. Based on the restframe ultraviolet flux a star formation rate of 2.1 +/- 0.2 M, yr(-1) is estimated. The best fit to the SED is obtained for a starburst template with an age of 0.181(-0.026)(+0.037) Gyr and a very low extinction (A(v) similar to 0).

In order to characterize the stellar population and other continuum sources (e.g. featureless continuum, FC) we have measured the equivalent width, W , of six absorption features, four continuum colours and their radial variations, and performed spectral population synthesis as a function of distance from the nucleus. About half of the sample has Ca iiK and G band W values smaller at the nucleus than at 1 kpc from it, owing to a younger population and/or FC. The stellar population synthesis shows that, while at the nucleus, 75 per cent of the galaxies present contribution >20 per cent of ages less than or equal to100 Myr and/or of an FC, this proportion decreases to 45 per cent at 3 kpc. In particular, 55 per cent of the galaxies have a contribution >10 per cent of the 3-Myr/FC component (a degenerate component in which one cannot separate what is caused by an FC or by a 3-Myr stellar population) at the nucleus, but only 25 per cent of them have this contribution at 3 kpc. As a reference, the stellar population of 10 non-Seyfert galaxies, spanning the Hubble types of the Seyfert (from S0 to Sc) was also studied. A comparison between the stellar population of the Seyferts and that of the non-Seyferts shows systematic differences: the contribution of ages younger than 1 Gyr is in most cases larger in the Seyfert galaxies than in non-Seyferts, not only at the nucleus but up to 1 kpc from it."

We present Very Large Array observations, made in the highest angular resolution A configuration, of H2O maser emission toward this source. Our data show that the H2O spots appear to be segregated in two velocity groups: a group with radial velocity similar to that of the ambient cloud (V-LSR similar or equal to 8 km s(-1)) that is associated with the western radio source, and a blueshifted (by similar to20 km s(-1)) velocity group that is associated with the eastern radio source.

These structures, while smaller than the VLA beam, are 6-200 times the size of the VLBA synthesized beam. The morphology and the observed proper motions found in these structures imply three different centers of star formation activity in a region of similar or equal to 0.""3 radius (similar or equal to 200 AU). The most remarkable result from these observations is the discovery of an arc of water masers which is perfectly fitted by a circle to one part in a thousand. This arc is expanding and suggests a spherical ""puff"" of ejected material ejected 33 years ago from a protostar located 600 mas south of the radio jet HW2.

Pre- and post-perihelion CCD images of the gas (CN, C-2) and dust (green and red continua) coma were obtained with the 82 cm IAC-80 telescope at Teide Observatory (Canary Islands, Spain). For vp = 0.85r(H)(-0.5) and v(d) = 1.19 km s(-1) (i.e. characteristic of HCN being the CN parent species), the CN column density profiles are best reproduced with parent and daughter lifetimes of the order of 19 300 and 256 000 s. An equally good reproduction of the observed profiles is achieved by considering that a mixture of nitrogen compounds expanding at v(p) = 1 km s(-1) and with a lifetime of 19 000 s produces CN with an ejection velocity of v(d) = 2.5 km s(-1) and a lifetime of 174 000 s. Fitting the observed CN profiles with variable velocities and lifetimes, the results indicate that the nature of the CN precursor in comet 21P/Giacobini-Zinner is still unclear, ruling out HCN as the only precursor and favouring a mixture of nitrogen compounds. Regarding C-2, the derived lifetimes are 35 000 and 62 000 s, if the parent and daughter velocities are fixed at similar to1 km s(-1). Gas production rates derived by means of the Vectorial modeling with the mentioned above lifetimes and velocities indicate that (i) the comet activity decreases with decreasing r(H) (i.e. peak activity is not reached at the perihelion), and (ii) as already known, the comet is typically depleted in C-2 with a log Q(C2)/Q(CN) approximate to -0.4. The azimuthally averaged surface brightness profiles of the continuum images are well fitted with m greater than or equal to 1 in a log B-log rho representation at projected radial distances (rho) larger than 1000 km. The continuum light scattered from the dust in the coma of comet Giacobini-Zinner is redder than the Sun light on every date from Nov. 8 to 24, regardless the cometocentric distance. On Nov. 25, there is a sudden change in the dust color, being considerably bluer than the Sun, whereas on Dec. 7 and 8, the dust became much redder than it was before. These color variations do not seem to be related to sudden variations (relative minimum or maximum) in the cometary activity. The gas-to-dust mass ratio is similar to1, but affected by a large uncertainty (about a factor of 2) since the comet was not simultaneously imaged in the OH band, and the H2O production rate has been considered from other measurements taken some weeks before ours."

Therefore, screening for antibodies to Trypanosoma cruzi is mandatory in blood banks in South America. Most of the commercial serologic tests employ epimastigote antigens and show a high number of inconclusive and false-positive results, with high economic and social costs. STUDY DESIGN AND METHODS: An ELISA using a mixture of three T. cruzi recombinant antigens, B13, 1F8, and H49 (mix-ELISA), was evaluated, first with a panel of well-characterized sera from 617 patients with Chagas' disease and 277 nonchagasic individuals, living in nine countries of South and Central America. Subsequently, the mix-ELISA was evaluated with 451 samples, from an endemic area of Brazil (Goias), that were rejected from several blood banks because they presented discrepant results by two commercially available kits (indirect immunofluorescence assay, indirect hemagglutination assay, and/or ELISA). RESULTS: The mix-ELISA exhibited 99.7 percent sensitivity and 98.6 percent specificity in the first evaluation with the 894 samples. In the second evaluation, 451 sera that had discrepant results in the first screening for Chagas' disease were further analyzed with the mix-ELISA. Upon consideration of the consensus results obtained with the trypomastigote excreted-secreted antigens blot test, a confirmatory test for Chagas' disease, the mix-ELISA led to a reduction in 99.6 percent in the number of discordant sera. CONCLUSION: The combination of three T. cruzi recombinant antigens in a multiantigen immunoassay was highly sensitive and specific for Chagas' disease diagnosis. It is proposed that it can be applicable in blood bank screening in conjunction with the conventional serologic tests."

We present the results of our observing campaign at radio wavelengths which began in August 1995 and ended in January 2002. The observations were carried out with the telescopes of Nancay, IRAM, JCMT, CSO and, since September 1997, SEST. The lines of nine molecules (OH, CO, HCN, CH3OH, H2CO, H2S, CS, CH3CN and HNC) were monitored. CS, H2S, H2CO, CH3CN were detected up to r(h) = 3-4 AU from the Sun, while HCN and CH3OH were detected up to 6 AU. CO, which is the main driver of cometary activity at heliocentric distances larger than 3-4 AU, was last detected in August 2001, at r(h) = 14 AU. The gas production rates obtained from this programme contain important information on the nature of cometary ices, their thermal properties and sublimation mechanisms. Line shapes allow to measure gas expansion velocities, which, at large heliocentric distances, might be directly connected to the temperature of the nucleus surface. Inferred expansion velocity of the gas varied as r(h)(-0.4) within 7 AU from the Sun, but remained close to 0.4 km s(-1) further away. The CO spectra obtained at large r(h) are strongly blueshifted and indicative of an important day-to-night asymmetry in outgassing and expansion velocity. The kinetic temperature of the coma, estimated from the relative intensities of the CH3OH and CO lines, increased with decreasing r(h), from about 10 K at 7 AU to 110 K around perihelion."

The tmoX gene is also the initial gene in the tmoXABCDEF gene cluster. The transcription initiation point from the tmoX promoter was mapped, and the sequence upstream revealed striking identity with the promoter of the tod operon of P. putida. The tod operon is regulated by a two-component signal transduction system encoded by the todST genes. Two novel genes from P. mendocina KR1, tmoST, were rescued by complementation of a P. putida DOT-TIE todST knockout mutant, whose gene products shared about 85% identity with TodS-TodT.

In this work, the reaction of the atomic radicals, H, O(P-3), F and Cl with toluene has been studied using ab initio theoretical methods to compare the stability of the isomeric adducts and to predict their expected hyperfine coupling constants. Ipso addition is found to be favored only for fluorine, although the ipso and ortho isomers have very similar energies for oxygen and chlorine.

We model the centimetre and millimetre continuum spectrum in terms of free-free emission from an ionized core-halo source. In this model a dense (2.6 x 10(6) cm(-3)), optically thick inner core dominates the millimetre emission, while a low-density (1 x 10(4) cm(-3)), optically thin halo dominates the centimetre emission. The spectral index of the core (between 2 cm and 7 mm) is alpha similar or equal to 1.6 +/- 0.1 (S-nu proportional to nu(alpha)), which is consistent with optically thick free-free emission.

Both isoforms showed strong identity with other known CK1s. Their corresponding genes encode proteins of 312- and 330-amino acid residues with apparent molecular weights of 16 and 37 kDa, respectively. TcCK1.1 is a two-copy gene while TcCK1.2 is tandemly repeated, an arrangement not yet found in any other CK1. TcCK1.1 has been overexpressed in Escherichia coli and the recombinant protein exhibited properties characteristic of the CK1 family. Northern blot indicated that both TcCK1s are expressed differentially during the life stages of the parasite: the isoform TcCK1.1 shows low levels of mRNA expression in epimastigotes and increased expression in trypomastigotes while TcCK1.2 presents an augmented expression in amastigotes as compared with the other two life stages of the parasite. The CK1-like activity of amastigotes and trypomastigotes is significantly higher than that of epimastigotes and, independent of the life stage of the parasite, a constitutive activity is observed which, in the epimastigote forms, is found predominantly in the microsomal fraction. Also in the epimastigote forms, the CK1-like activity increases in the log phase of growth of the parasites, and, through synchronization studies, this activity has been most conspicuously circumscribed to the S and M phases of the cell cycle.

In total 28 objects were observed of which 18 are new measurements. Combining our new BVRI photometry with the data summary published by Hainaut & Delsanti (2002) results in a database of 94 objects: 45 Cubewanos, 22 Plutinos, 13 scattered disk objects, 14 Centaurs. The reddening range seems to be similar among the four dynamical classes (-5 to 55%/100 nm) and only one outlier (1994 ES2) exists. The spectral gradient distribution of the Cubewanos peaks between 25 to 35%/100 nm, while for the three other types the maximum seems to fall below 20%/100 nm. A clustering of red Cubewanos with perihelia beyond similar to41 AU in low eccentricity and low inclination orbit suggests that these objects are less affected by the physical processes that potentially produce neutral colors, i.e. resurfacing by collision and by intrinsic activity. For Cubewanos and scattered disk objects, the range of reddening increases with decreasing perihelion distance and with increasing orbital excitation. A correlation of the spectral slope with inclination is present for Cubewanos and scattered disk objects, and is non-existent for the other dynamical types. It is unclear whether these trends (or their absence) are discriminative for the correctness of the resurfacing scenarios. If intrinsic activity is responsible for resurfacing, the start of the effect inside similar to41 AU from the Sun may be indicative for the driving agent, while in the collision scenario the survival of the red Cubewano cluster in the central region of the Kuiper-Belt argues for the existence of a population of bodies the surface of which is heavily radiation processed without impact resurfacing."

The results show evidence for a difference in the near-infrared spectral behaviour obtained during two observations carried out one month apart. In one spectrum there is the possible presence of signatures of water ice in small amounts. Two models have been proposed to interpret the surface composition of this Centaur.

It possesses a rich intergalactic medium (IGM), where hydrogen clouds, both atomic and molecular, associated with two starbursts (refered to as SQ A and B) have been found. In order to study the extent, origin and fate of the intergalactic molecular gas and its relation to the formation of stars outside galaxies and Tidal Dwarf Galaxies (TDGs), we mapped with the IRAM30 m antenna the carbon monoxide (CO) towards several regions of the IGMin SQ. In both SQ A and B, we detected unusually large amounts of molecular gas (3.1 x 10(9) M-. and 7 x 10(8) M-., respectively). In contrast, no significant CO detection was achieved towards HII regions south of the pair NGC 7318a/b despite their high Halpha luminosities. The molecular gas is very extended in both SQ A and SQ B, over areas of between 15 and 25 kpc. The CO clouds seem to have otherwise different properties and may be of a different nature. The integrated CO line of SQ A is in particular much wider than in SQ B. Its CO spectrum shows emission at two velocities (6000 and 6700 km s(-1)) that are coincident with two HI lines. The strongest emission at 6000 km s(-1) is however spatially offset from the HI emission and situated on a ridge south-east of the starburst region. In SQ B the CO emission coincides with that of tracers of star formation (Halpha, 15 mum and radio continuum). The CO peak lies slightly offset from the HI peak towards a steep HI gradient. This is indicating that the molecular gas is forming in-situ, possibly in a region of compressed HI, with subsequent star formation. The star forming region at SQ B is the object in SQ that most resembles a TDG."

The microbial inocula consisted of a wild type (WT) Rhizobium meliloti strain, the arbuscular mycorrhizal (AM) fungus Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe, and a phosphate solubilizing rhizobacterium (Enterobacter sp.). Inoculated microorganisms were established in the root tissues and/or in the rhizosphere soil of alfalfa plants (Medicago sativa L.). Improvements in N and P accumulation in alfalfa corroborate beneficial effects of Rhizobium and AM interactions. Inoculation with selected rhizobacteria improved the AM effect on N or P accumulation in both the RP-added soil and in the non RP-amended controls. Measurements of the N-15/N-14 ratio in plant shoots indicate an enhancement of the N-2 fixation rates in Rhizobium-inoculated AM-plants, over that achieved by Rhizobium in non-mycorrhizal plants. Whether or not RP was added, AM-inoculated plants showed a lower specific activity (P-32/P-31) than did their comparable non-mycorrhizal controls, suggesting that the plant was using otherwise unavailable P sources. The phosphate-solubilizing, AM-associated, microbiota could in fact release phosphate ions, either from the added RP or from the indigenous ""less-available"" soil phosphate. A low Ca concentrations in the test soil may have benefited P solubilization. Under field conditions, the inoculation with AM fungi significantly increased plant biomass and N and P accumulation in plant tissues. Phosphate-solubilizing rhizobacteria improved mycorrhizal responses in soil dually receiving RP and organic matter amendments. Organic matter addition favoured RP solubilization. This, together with a tailored microbial inoculation, increased the agronomic efficiency of RP in the test soil that was Ca deficient at neutral pH."

"The addition of plant residues and the appropriate management of arbuscular mycorrhizal (AM) symbioses have been tested in an acidic soil, an Andisol from Southern Chile, to ascertain whether these agro-technologies help plants to withstand potential mineral deficiency and the toxicities inherent to the low pH conditions. Firstly, the effects of legume (lupine) and non-legume (wheat) crop residues on some key root-soil interface activities (including AM development), on mineral acquisition by the plants, and on the yield of wheat growing in the test Andisol were investigated in a pot experiment under greenhouse conditions. Both lupine and wheat residues were added at a rate equivalent to 300 g m(-2) to the natural soil. These organic amendments increased soil pH (wheat more than lupine), P availability and AM development (lupine more than wheat), plant performance and mineral acquisition (wheat more than lupine). Because of an increase in mycorrhizal activity, which appeared to be involved in the effect of the added crop (particularly lupine) residues, the role of the AM symbiosis was further investigated in a tailored inoculation assay, using a selected AM fungus (Glomus etunicatum), in interaction with lupine and wheat residues. A significant effect of AM inoculation on the reduction of Zn and Cu, and Mn and Al acquisition was demonstrated, which could be of interest in acid soils with regard to potential toxicity problems."

The spectroscopic data are used to derive the internal extinction and to compute metallicities, electronic density, and temperature in the knots. By subtracting the contribution of the underlying older stellar population, modeled by an exponential function, removing the contribution from emission lines, and correcting for extinction, we can measure the true colors of the young star-forming knots. We show that the colors obtained this way differ significantly from those derived without the above corrections and lead to different estimates of the ages and star-forming history of the knots. Using predictions of evolutionary synthesis models, we estimate the ages of both the starburst regions and the underlying stellar component. We found that we can reproduce the colors of all the knots with an instantaneous burst of star formation and the Salpeter initial mass function ( IMF) with an upper mass limit of 100 M-circle dot. The resulting ages range between 3 and 6 Myr. The colors of the low surface brightness component are consistent with ages larger than 5 Gyr. The kinematic results suggest ordered motion around the major axis of the galaxy."

Early near-infrared (NIR) H and K' observations are also reported. The afterglow was optically faint (R approximate to 23) at discovery but did not exhibit an unusually rapid decay (power-law decay slope alpha < 1 : 8 at 2&sigma;). The optical/NIR spectral index (&beta;(RH) < 1.1) was consistent with the optical-to-X-ray spectral index (beta(RX) approximate to 0.6), indicating a maximal reddening of the afterglow of approximate to0.45 mag in R. Hence, the dimness of the optical afterglow was mainly due to the fairly at spectral shape rather than internal reddening in the host galaxy. We also present late-time Hubble Space Telescope/Space Telescope Imaging Spectrograph images of the field in which GRB 980613 occurred, obtained 799 days after the burst. These images show that GRB 980613 was located close to a very compact, blue V = 26 : 1 object inside a complex region consisting of star-forming knots and/or interacting galaxy fragments.

Design: Randomized, controlled study. Setting: Experimental Unit, Virgen de las Nieves University Hospital. Subjects: Seventy-two female CBA/H mice, 20-21 g, supplied by the animal center of the Experimental Unit. Intervention: The mice were randomized into three groups of 24. Group 1 (sham) received two intraperitoneal doses of 0.1 mL of phosphate-buffered saline; group 2 (lipopolysaccharide) was injected with 125 mg/kg lipopolysaccharide (Escherichia coli, intraperitoneally) 24 hrs after 0.1 mL of phosphate-buffered saline; group 3 was pretreated with 80 ng of recombinant interleukin-1beta per mouse (intraperitoneally) 24 hrs before the endotoxic challenge. Measurements and Main Results: At 1, 2, 4, and 24 hrs after the endotoxic challenge, we studied inflammatory infiltrate and tissue damage in lung, liver, and intestine by determining myeloperoxidase and malondialdehyde tissue concentrations. When we compared the pretreated group with the lipopolysaccharide group, myeloperoxidase concentrations decreased significantly in lung (p < .001) and liver (p < .001) at all study times, and in intestine (p < .001) at 2, 4, and 24 hrs; malondialdehyde concentrations significantly decreased in lung at 1 (p < .05), 2 (p < .01), and 24 (p < .001) hrs, in liver at 2 (p < .001), 4 (p < .01), and 24 (p < .001) hrs, and in intestine at 1 (p < .001), 2, 4 (p < .05), and 24 (p < .001) hrs.

Shoot and root dry biomass, AM colonized root length, macro-micronutrients content and soil phosphatase (P-ase) activity were determined after six months of plant growth. The inoculated G. etunicatum fungus, a fungal strain adapted to the prevailing soil conditions, enhanced plant growth (shoot and root biomass) and mineral acquisition of some elements when plants were fertilized with pa-PR but not with soluble P. The nutrient acquisition by AM inoculated plants varied with the source and amount of applied P. When pa-PR was supplied, the inoculated AM fungus enhanced P, potassium (K), aluminum (Al), and manganese (Mn) plant acquisition in comparison with indigenous endophytes alone. Shoot zinc (Zn) and copper (Cu) uptakes were also enhanced by G. etunicatum inoculation only at the intermediate assayed pa-PR level (43 kg ha(-1)). AM root colonization in the efficient pa-PR treatments, did not relate well to the plant growth and nutrient acquisition in most cases. Nutrients (Ca and Mg) that increased in AM inoculated plants were not those commonly deficient in acidic soils. Nevertheless, some nutrients, which often become limiting under low pH conditions such as P and K were increased by G. etunicatum inoculation plus pa-PR. Changes in rhizospheric soil pH under pa-PR application may be involved in these mycorrhizal effects on nutrient acquisition. The increases in plant biomass as a result of mycorrhizal inoculation do not seem to account for all the changes observed in mineral acquisition. The highest soil P-ase activity was observed at the lowest pa-PR dose showing a negative relationship with P-availability. The inoculation of G. etunicatum was effective in this natural acidic soil in overcoming factors that restrict plant growth and nutrition when pa-PR was applied."

The complex resembles a circular bubble 600 pc in diameter with a young super star cluster (SSC) near the center. The kinematics of ionized gas is studied through Halpha emission with several slit positions. Position-velocity diagrams show two distinct features with high speed motions. One is an irregularly shaped region to the east of the SSC, 270 pc in size, in which most of the Halpha emission is blue shifted by 120 km s(-1), and another is a 350 pc shell centered on the SSC with positive and negative velocity shifts of 60 km s(-1). Balmer and He I absorption lines in the SSC give an age of 12-13 Myr, which is consistent with the photometric age but significantly older than the kinematic ages of the high speed regions. The energetics of the SSC and its interaction with the environment are considered. The expansion energies exceed 10(52) ergs, but the power outputs from winds and supernova in the SSC are large enough to account for this. The intensities of Balmer, [N II], and [S II] emission lines within and around the complex indicate that shock excitation makes a significant contribution to the emission from the most energetic region."

Both formations are affected by low-grade metamorphism. The mixed-layer minerals were studied by optical microscopy, X-ray diffraction (XRD), electron microprobe (EMPA), and transmission/analytical electron microscopy (TEM/AEM). Two types of phyllosilicates were identified: chlorite-vermiculite and mica-chlorite, which are present in the Palaeozoic and Triassic rocks respectively. Chlorite-vermiculite mixed layers form packets with well-defined boundaries and mainly show 1:1 ordered sequences. On the contrary, mica-chlorite mixed layers show, in most cases, random sequences evolving laterally toward chlorite. The AEM data indicate compositions close to that of chlorite in the ternary Si-Al(Fe+Mg+Mn) diagrams for both types of mixed-layer phyllosilicates. Relative to the coexisting chlorite, they have lower (Fe+Mg) contents, and a higher Si/Al ratio. They are interpreted as products of the transformation of chlorite, developed during prograde metamorphism, and probably represent intermediate, metastable phases, in the chlorite to biotite transformation."

Recent observations have revealed that in the radio continuum (3.6-cm) the source is a binary with components separated by about 0.""3 in the east-west direction. The members of the binary are named VLA 4A (western component) and VLA 4B (eastern component). In an attempt to ascertain which of the two components of the binary is the most likely candidate to drive the outflow, we obtained accurate positions for the H2O maser spots toward this source, also known as H2O(A), derived from Very Large Array observations in its highest angular resolution A configuration. We detected a total of eleven spots over four observational sessions (made in the years 1983, 1985, 1988, and 1989). The spots are segregated in two velocity groups: a velocity group with v(LSR) similar to that of the ambient cloud (v(LSR) similar or equal to 8 km s(-1)), for which we detected five features (with v(LSR) in the range of 6.5 to 12.2 km s(-1)) and a blueshifted velocity group (six features with vLSR in the range of -25.4 to 5.6 km s(-1)). Remarkably, all the spots in the first velocity group are associated with VLA 4A, while all the spots in the blueshifted velocity group are associated with VLA 4B. We discuss the possible implications of this observation. We also present accurate positions of the H2O maser HH 7(B) and of the masers associated with IRAS4B (VLA 28) and IRAS7 (VLA 27, the exciting source of HH 6)."

Air temperature under the cover was higher at the beginning of the cropping season, as compared with open-air growing, but differences decreased throughout the crop cycle. Transmission of PPFD under cover varied from 85 to 65%, depending on dust accumulation on the cover and water vapour condensation in the inner surface of the fabric. Above-ground crop biomass at harvest was not influenced by direct covering (CO) relative to open air (OA) growing conditions. The enhancement of leaf area development, due to the more adequate temperature conditions in CO plots, was compensated by the reduction of the incoming PPFD under CO. Beet root biomass was significantly higher in the CO plots. The larger leaf area index (LAI) and similar values of above-ground biomass under CO indicate a larger production of thinner leaves, reaching significantly higher specific leaf area (SLA) at harvest in the CO cabbage, lettuce and spinach crops, contributing to an important rise in the quality of the marketable product.

There is an apparent kinematic discontinuity between the bright bipolar core and the outer regions.

(1998) with 0.06"" resolution toward L1551 IRS5 have shown two resolved dust sources. Both sources are elongated with almost the same orientation, similar flux densities, and similar angular sizes, being interpreted by these authors as a system of twin, aligned protoplanetary disks of 10 AU radius around the components of a young binary of 50 AU separation. These protoplanetary disks, the smaller ones ever imaged at mm wavelengths, are about a factor of ten smaller than disks around isolated stars, but have enough mass to form solar systems similar to our own. The fact that the disks are aligned with each other argues in favor for long-lived planetary systems in this binary. We all look forward to the future development of interferometers such as the EVLA, SMA, and ALMA in order to characterize the physical conditions of these associated protoplanetary disks by detecting spatially resolved molecular line emission. With these upcoming interferometers it will be possible to make great strides forward in our knowledge of the star formation processes."

We measured the intensities of several H and He recombination lines, and of forbidden lilies of a large number of ions. We calculate the physical conditions in the, two nebulae with a large number of diagnostics and determine their chemical abundances by applying ionization correction factors (icf's) to the observed ionic abundances. For NGC 5461, the icf's are based on a tailored photoionization model of the region (Luridiana & Peimbert 2001), while for NGC 5471 they are computed from those predicted by a photoionization model of NGC 2363 (Luridiana, Peimbert, & Leitherer 1999), a region which is similar to NGC 5471 in the ionization structure. For both regions, the icf's are compared to those computed following the prescriptions by Mathis & Rosa (1991).

This is one of the largest coordinated set of observations ever performed for this source, covering the wide energy band in radio (13.3-0.3 cm), near-infrared (J, H, and K bands), X-rays, and gamma rays (from 1 keV to 10 MeV). During the campaign GRS 1915+105 was predominantly in the plateau (or low/hard) state but sometimes showed soft X-ray oscillations: before April 20.3, rapid, quasi-periodic (similar or equal to45 minutes) flare-dip cycles were observed. In the spectral energy distribution in the plateau state, optically thick synchrotron emission and Comptonization is dominant in the radio and X- to gamma-ray bands, respectively. The small luminosity in the radio band relative to that in X-rays indicates that GRS 1915+105 falls in the regime of ""radio-quiet"" microquasars. In three epochs we detected faint flares in the radio or infrared bands with amplitudes of 10-20 mJy. The radio flares observed on April 17 shows frequency-dependent peak delay, consistent with an expansion of synchrotron-emitting region starting at the transition from the hard-dip to the soft-flare states in X-rays. On the other hand, infrared flares on April 20 appear to follow (or precede) the beginning of X-ray oscillations with an inconstant time delay of similar or equal to5-30 minutes. This implies that the infrared-emitting region is located far from the black hole by greater than or similar to10(13) cm, while its size is less than or similar to10(12) cm constrained from the time variability. We find a good correlation between the quasi-steady flux level in the near-infrared band and in the X-ray band. From this we estimate that the reprocessing of X-rays, probably occurring in the outer parts of the accretion disk, accounts for about 20%-30% of the observed K magnitude in the plateau state. The OSSE spectrum in the 0.05-10 MeV band is represented by a single power law with a photon index of 3.1 extending to similar to1 MeV with no cutoff. We can model the combined GIS-PCA-HEXTE spectra covering 1 200 keV by a sum of the multicolor disk model, a broken power law modified with a high-energy cutoff, and a reflection component. The power-law slope above similar to30 keV is found to be very similar between different states in spite of large flux variations in soft X- rays, implying that the electron energy distribution is not affected by the change of the state in the accretion disk."

The B field is assumed parallel to the arm, and the model results are applied to the optical segment of the Carina-Sagittarius arm. The characteristic features of the undular and interchange modes are clearly apparent in the simulations. The interchange mode appears first and generates small interstellar structures in the interarm regions, but its development inside the arm is hampered by the acceleration of the spiral wave. In contrast, the undular mode follows its normal evolution inside the spiral wave, creating large gas concentrations distributed along the arm. This results in a clear arm/interarm difference; the instability triggers the formation of large interstellar clouds ( with masses in the range of 10(6)-10(7) M-circle dot) inside the arms but generates only small structures with slight density enhancements in the interarm regions. The resulting clouds are distributed in an antisymmetric way with respect to the midplane, and their masses are similar to those inferred for H I superclouds in our Galaxy. Such a cloud distribution results in an azimuthal corrugation along the arm, and for conditions similar to those of the optical segment of the Carina-Sagittarius arm, it has a wavelength of about 2.4 kpc. This structuring, then, can explain the origin of both H I superclouds and the azimuthal corrugations in spiral arms. In particular, the wavelength of the fastest growing undular mode matches the corrugation length derived with the young stellar groups located in the optical segment of the Carina-Sagittarius arm."

We provide here information about this source of forage: allometric regression equations (phytovolume vs. total and forage phytomass), nutritive value and seed germination. The regression equations calculated were highly significant (r(2)=0.86 for volume/total phytomass and 0.93 for volume/forage phytomass, p<0.001). The values recorded for the in vitro digestibility of dry matter and organic matter were 65.93% and 62.13%, respectively. The optimum temperature for seed germination was 10 degrees C. Scarification in goat rumen for 24h increased the overall germination rate of fruit with pericarp although in sheep rumen overall germination decreased slightly.

We analysed retrospectively the results of 151 ICSI cycles in which sperm of vasectomized men were used at different time periods after vasectomy. METHODS: Oocytes were obtained after a desensitizing ovarian stimulation protocol using GnRH agonist in association with recombinant FSH and HCG. Sperm were retrieved by percutaneous epididymal sperm aspiration. The cycles were split into three groups: less than or equal to10 years after vasectomy (group 1, n = 47), 11-19 years after vasectomy (group 2, n = 79), and greater than or equal to20 years after vasectomy (group 3, n = 25). RESULTS: As might be expected, the mean age of men differed in the three groups (group 3 > group 2 > group 1), and the mean age of the women was also significantly higher in group 3 than in groups 1 and 2, although no differences were described between groups 2 and 3. All other laboratory and clinical parameters were similar in the three groups. Ongoing pregnancy and implantation rates (34, 25, 8% and 22, 15, 6% respectively) decreased significantly from group 1 to group 3. CONCLUSION: Pregnancy and implantation rates after ICSI with sperm from vasectomized men are negatively correlated with the time interval from vasectomy, which cannot be explained purely by male or female ageing."

The complex is peculiar because of its very high density of stars and clusters and semicircular shape. Its physical dimensions are about the same as for the local Gould Belt, but the stellar density is 1-2 orders of magnitude higher. In addition to an extremely luminous, similar to15 Myr old cluster discussed in an earlier paper, accounting for about 17% of the integrated V-band light, we identify 18 stellar clusters within the complex with luminosities similar to the brightest open clusters in the Milky Way. The color-magnitude diagram of individual stars in the complex shows a paucity of red supergiants compared to model predictions in the 10-20 Myr age range for a uniform star formation rate. We thus find tentative evidence for a gap in the dispersed star formation history, with a concentration of star formation into a young globular cluster during this gap. Confirmation of this result must, however, await a better understanding of the late evolution of stars in the corresponding mass range (greater than or similar to12 M.). A reddening map based on individual reddenings for 373 early-type stars is presented, showing significant variations in the absorption across the complex. These may be responsible for some of the arclike structures previously identified on ground-based images. We finally discuss various formation scenarios for the complex and the star clusters within it."

Three embedded young stellar objects (YSOs) were found within a projected area of similar or equal to 0"".6 x 0"".6 (400x400 AU(2)). One of the sources is the already known radio continuum jet HW2 (detected at 3.6 cm and 7 mm), while the other two weak sources were not previously known. One of these two new sources is detected only at 7 mm and is located similar or equal to0"".15 south from HW2. The other source, detected only at 3.6 cm, is located 0"".6 south from HW2 and nearly coincides with the center of the enigmatic expanding bubble of water masers recently detected with the Very Long Baseline Array. We suggest that this radio continuum source is the embedded YSO powering the water maser structure, but its nature is still unknown at present.

The H alpha trails correspond in position and length with tails of syncrotron radiation. At the galaxy side opposite to the tails, the two galaxies show bright H II regions aligned along arcs, where the star formation takes place at the prodigious rate of similar to1 M-. yr(-1). From the morphology of the galaxies and of the trailing material, we infer that the two galaxies are suffering from ram pressure due to their high-velocity motion through the cluster intergalactic medium. We estimate that similar to 10(9) M-. of gas, probably ionized in the giant H ii regions, is swept out, forming the tails. The tails cross each other at some 100 kpc from the present galaxy location, indicating that a major tidal event occurred some similar to 5 x 10(7) yr ago. We exclude that mutual harassment produced the observed morphology, and we show with numerical simulations that it could have marginally aided ram pressure stripping by loosening the potential well of the galaxies."

They are detected in the echelle spectra in the H alpha and [N II] lines but not in other nebular lines. The [N II]/H alpha ratio is uniformly high, similar or equal to1. The observed kinematics reveals bipolar collimated outflows in the jetlike features and shows that the southeast (northwest) component expands toward (away from) the observer at a remarkably constant line-of-sight velocity, 26.0 +/- 0.5 km s(-1). The observed expansion velocity and the opening angle of the jetlike features are used to estimate an inclination angle of similar or equal to5 degrees with respect to the sky plane and a space expansion velocity of similar or equal to 290 km s(-1). The spectrum of the bright central nebula reveals a profusion of Fe lines and extended wings of the H alpha line, similar to those seen in symbiotic stars and some young planetary nebulae that are presumed to host a mass-exchanging binary system. If this is the case for He 2-90, the constant velocity and direction of the jets require a very stable dynamic system against precession and warping."

The intrusion is particularly interesting because a previous intruder had stripped most of the gas from the group members. This debris field was shocked in the ongoing collision with the new intruder. This evolutionary history agrees well with observations and explains how a strongly interacting system can show low levels of star formation. We present new multiwavelength data including previously unpublished ROSAT X-ray, Ha interference ISO MIR/FIR, and filter/Fabry-Perot, radio line and continuum images. These observations and previously published data provide new insights, as well as support for some previous hypotheses. (1) and H I velocities allow us to Fabry-Peerot unambiguously distinguish between gas associated with SQ and the new intruder. (2) Most detected emission regions are found in the remnant interstellar medium (ISM) of the new intruder, which allows us to infer its size and present physical state. (3) The few emission regions associated with the stripped ISM of SQ include the best candidate tidal dwarf galaxy. (4) Multiwavelength data suggest that strong MIR/FIR emission from the Seyfert 2 nucleus of NGC 7319 comes from dust heated directly by a power-law continuum rather than a starburst. (5) The correspondence between extended X-ray/radio continuum/forbidden optical emission confirms the existence of a large scale shock in SQ. (6) We confirm the presence of two stripped spiral members in the process of transformation into E/S0 morphology. Finally (7) observations are consistent with the idea that the collision in SQ is ongoing with possible detection of H II region ablation and Rayleigh-Taylor instabilities."

The absolute configurations of eight hetero- and homochromophoric compounds, 1, 3, 6-9, 12, and 13, were determined by means of CD studies. Fourteen compounds, 1-3 and 6-16, have been tested on a multidrug-resistant Leishmania tropica line overexpressing a P-glycoprotein-like transporter to determine their ability to revert the resistance phenotype and to modulate intracellular drug accumulation.

Since they are relaxed systems in a post violent-relaxation stage, they are quasi-equilibrium gravitational systems and therefore they also have a quasi-constant specific entropy. Assuming that light traces mass, these two laws imply that in the space defined by the three Sersic law parameters (intensity Sigma (0), scale a and shape v), elliptical galaxies are distributed on two intersecting 2-manifolds: the Entropic Surface and the Energy-Mass Surface. Using a sample of 132 galaxies belonging to three nearby clusters, we have verified that ellipticals indeed follow these laws. This also implies that they are distributed along the intersection line (the Energy-Entropy line), thus they constitute a one-parameter family. These two physical laws (separately or combined), allow to find the theoretical origin of several observed photometrical relations, such as the correlation between absolute magnitude and effective surface brightness, and the fact that ellipticals are located on a surface in the [log R-eff, -2:5 log Sigma (0); log v] space. The fact that elliptical galaxies are a one-parameter family has important implications for cosmology and galaxy formation and evolution models. Moreover, the Energy-Entropy line could be used as a distance indicator."

This extended emission shows a radial velocity stratification, with higher radial velocities oil the jet axis and lower velocities away from the axis. Knot D has a low central electron density surrounded by material with higher electron densities, while the electron density is approximately constant across knot F.

These CCR5 polymorphisms were assessed in 85 seropositive (asymptomatic, n=53; cardi- omyopathic, n=32) and 87 seronegative individuals. The extremely low frequency (0.009) of the CCR5 Delta 32 allele in our population did not allow us to analyse its possible influence on T cruzi infection.

The spherical symmetry of the giant phase is lost in the transition to a planetary nebula, when nonspherical shells and powerful jets develop. Molecules that were present in the giant envelope are progressively destroyed by the radiation(1). The water-vapour masers that are typical of the giant envelopes(2,3) therefore are not expected to persist in planetary nebulae(1,4). Here we report the detection of water-maser emission from the planetary nebula K3-35. The masers are in a magnetized torus with a radius of about 85 astronomical units and are also found at the surprisingly large distance of about 5,000 astronomical units from the star, in the tips of bipolar lobes of gas. The precessing jets from K3-35 are probably involved in the excitation of the distant masers, although their existence is nevertheless puzzling. We infer that K3-35 is being observed at the very moment of its transformation from a giant star to a planetary nebula."

Deep contour maps, surface-brightness profiles, and color profiles were used to analyze and discuss their morphology and structure. Here, we present new U-band and H alpha observations. We compute isophotal and asymptotic magnitudes of the sample galaxies and total H alpha fluxes. Comparison with previous works is done to assess the quality of the data available for BCDs. Finally, we produce an atlas of detailed color and H alpha maps, the Drst systematic atlas of this kind published so far. The high quality of the data allows us to identify the different star-forming knots in the maps and to discriminate between them and the regions where star formation activity has already ceased. We supplement the atlas with a morphological description of each galaxy and group the galaxies in four classes according to the distribution of their star-forming regions."

The VLBA data show that some of the masers detected previously with the VLA unfold into unexpected and remarkable linear/arcuate ""microstructures,"" revealing, in particular three filaments (R1, R2, R3) with length sizes similar or equal to3-25 mas (2-18 AU) and unresolved in the perpendicular direction (less than or similar to0.1 AU), an arcuate structure (R4-A) of similar or equal to 20 mas size (15 AU), and a curved chain of masers (R5; which we have previously reported) of similar or equal to 100 mas size (similar or equal to 72 AU). Some of these structures unfold into even smaller linear ""building blocks"" (down to scales of 0.4 AU) shaping the ""larger"" structures. The flattened appearance of these small pieces argues strongly for a shock nature. Both the morphology and the observed proper motions found in these water maser structures have allowed us to identify at least three different centers of star formation activity in a region of similar or equal to 300 mas (200 AU) projected radius, unknown previously, and that could constitute a triple star system. We suggest that R1, R2, and R3, which are located close to the HW2 radio jet but offset by similar or equal to 200 mas with respect to its axis, could originate at the shocked walls of an inner cavity excavated by the HW2 wind in the circumstellar molecular gas. The presence of a wide-angle wind associated with the central HW2 object is implied. We also propose that the arcuate structure R4-A corresponds to a bow-shock structure produced by the wind of an undetected protostar (which we predict to be located toward the southeast of R4-A, similar or equal to 200 mas south from HW2). Finally, the third energy source of this small region could be that one exciting the arc R5, which, as we have previously reported, is expanding and related to an unidentified protostar located similar or equal to 600 mas south of HW2. The flux density of the water masers of the R5 arc excited by this unknown protostar (similar to 500 Jy) represents an important fraction (similar to 50%) of the total flux density of the maser emission in the entire Cepheus A star-forming region, suggesting that the exciting object could be a high-mass star. Furthermore, we find that the center of the circle, which Dt the R5 arc structure for each epoch, is moving with a velocity of similar to6 km s(-1). This could be caused by proper motions of the associated protostar because of relative orbital motions within the triple star system formed by HW2 and the energy sources of the R4-A and R5 structures."

These objects are formed of material torn off of the outer parts of a spiral disk due to tidal forces in a collision between two massive galaxies. Molecular gas is a key element in the galaxy formation process, providing the link between a cloud of gas and a bona fide galaxy. We have detected CO in 8 TDGs (two of them have already been published in Braine et al. 2000, hereafter Paper I), with an overall detection rate of 80%, showing that molecular gas is abundant in TDGs, up to a few 10(8) M-.. The CO emission coincides both spatially and kinematically with the HI emission, indicating that the molecular gas forms from the atomic hydrogen where the HI column density is high. A possible trend of more evolved TDGs having greater molecular gas masses is observed, in accord with the transformation of HI into H-2. Although TDGs share many of the properties of small irregulars, their CO luminosity is much greater (factor similar to 100) than that of standard dwarf galaxies of comparable luminosity. This is most likely a consequence of the higher metallicity (greater than or similar to1/3 solar) of TDGs which makes CO a good tracer of molecular gas. This allows us to study star formation in environments ordinarily inaccessible due to the extreme difficulty of measuring the molecular gas mass. The star formation efficiency, measured by the CO luminosity per H alpha flux, is the same in TDGs and full-sized spirals. CO is likely the best tracer of the dynamics of these objects because some fraction of the HI near the TDGs may be part of the tidal tail and not bound to the TDG. Although uncertainties are large for individual objects, as the geometry is unknown, our sample is now of eight detected objects and we find that the ""dynamical"" masses of TDGs, estimated from the CO line widths, seem not to be greater than the ""visible"" masses (HI + H-2 + a stellar component). Although higher spatial resolution CO (and HI) observations would help reduce the uncertainties, we find that TDGs require no dark matter, which would make them the only galaxy-sized systems where this is the case. Dark matter in spirals should then be in a halo and not a rotating disk. Most dwarf galaxies are dark matter-rich, implying that they are not of tidal origin. We provide strong evidence that TDGs are self-gravitating entities, implying that we are witnessing the ensemble of processes in galaxy formation: concentration of large amounts of gas in a bound object, condensation of the gas, which is atomic at this point, to form molecular gas and the subsequent star formation from the dense molecular component."

Fifteen galaxies present unambiguous signatures of recent episodes of star formation within approximate to 300 pc of the nucleus. When we relate this property to the Hubble type of the host galaxy, we find that the incidence of recent circumnuclear star formation increases along the Hubble sequence; it seems to be greater than that in non-Seyfert galaxies for the early Hubble types SO and Sa but similar to that in non-Seyfert galaxies for later Hubble types. In both early-type and late-type Seyfert galaxies, the presence of recent circumnuclear star formation is related to the galaxy morphology in the inner few kiloparsecs, as observed in Hubble Space Telescope images through the filter F606W by Malkan et al., who have assigned a late ""inner Hubble type"" to most Seyfert 2 galaxies with recent circumnuclear star formation. This new classification is due to the presence of dust lanes and spiral structures in the inner region. The presence of recent star formation around Seyfert 2 nuclei is also related to interactions: among the 13 galaxies of the sample with close companions or in mergers, nine have recent star formation in the nuclear region. These correlations between the presence of companions, the inner morphology, and the incidence of recent star formation suggest an evolutionary scenario in which the interaction is responsible for sending gas inward, which both feeds the active galactic nucleus and triggers star formation. The starburst then fades with time and the composite Seyfert 2 + starburst nucleus evolves to a ""pure"" Seyfert 2 nucleus with an old stellar population. This scenario can reconcile the hypothesis that the active nucleus in Seyfert galaxies is triggered by interactions with the results of previous studies, which find only a small excess of interacting galaxies in Seyfert samples when compared with non-Seyfert samples. The large excess can only be found early after the interaction, in the phase in which a composite (Seyfert+starburst) nucleus is observed."

We use the Sersic law to describe the light profile. The specific entropy (the Boltzmann-Gibbs definition) is then calculated assuming that the galaxy behaves as a spherical, isotropic, one-component system. We predict a relation between the three parameters of the Sersic law linked to the specific entropy, defining a surface in the parameter space, an `entropic plane'. We have analysed a sample of simulated merging elliptical galaxies (virtual) and a sample of galaxies belonging to the Coma Cluster (real). Both virtual and real galaxies are: 1) located in their own `entropic plane' and 2) in this plane, they are located on a straight line, indicating constant entropy: another physical property. A careful examination of the value of the specific entropy indicates a very small increase in the specific entropy with the generation after merging (virtual sample). Although one cannot distinguish between various generations for real galaxies, the distribution of specific entropy in this sample is very similar to that in the virtual sample."

Previous work has shown that nearly half (15) of these nuclei show the direct (but difficult to detect) spectroscopic signature at optical/near-UV wavelengths of the hot massive stars that power circumnuclear starbursts. In the present paper we examine a variety of more easily measured quantities for this sample, such as the equivalent widths of strong absorption features, continuum colors, emission line equivalent widths, emission line ratios and profiles, far-IR luminosities, and near-UV surface brightness. We compare the composite starburst + Seyfert 2 nuclei to ""pure"" Seyfert 2 nuclei, Starburst galaxies, and normal galactic nuclei. Our goals are to verify whether the easily measured properties of the composite nuclei are consistent with the expected impact of a starburst and to investigate alternative less demanding methods to infer the presence of starbursts in Seyfert 2 nuclei, applicable to larger or more distant samples. We show that starbursts do indeed leave clear and easily quantifiable imprints on the near-UV to optical continuum and emission line properties of Seyfert 2s. Composite starburst + Seyfert 2 systems can be recognized by: (1) a strong ""featureless continuum"" (FC), which dilutes the Ca II K line from old stars in the host's bulge to an equivalent width W-K < 10 Angstrom; (2) emission lines whose equivalent widths are intermediate between starburst galaxies and ""pure"" Seyfert 2's; (3) relatively low excitation line ratios, which indicate that part of the gas ionization in these Seyfert 2s (typically similar to 50% of H beta) is due to photoionization by OB stars; (4) large far-IR luminosities (greater than or similar to 10(10) L-circle dot); (5) high near-UV surface brightness (similar to 10(3) L-circle dot pc(-2)). These characteristics are all consistent with the expected impact of circumnuclear starbursts on the observed properties of Seyfert 2's. Furthermore, they offer alternative empirical diagnostics of the presence of circumnuclear starbursts from a few easily measured quantities."

The observations were done in the period October 1999 - May 2000, when 18 telescopes at 15 observatories were used to collect 253 light extrema during a total of 290 hours of time-series observations. The purpose of the observations was to investigate amplitude and period variability previously observed in this star, and to search for low-amplitude frequencies. We detect, apart from the main frequency and its two first harmonics, four additional frequencies in the light curves, all with low amplitudes (1-3 mmag). Combining the present data set with data obtained in 1998-99 at ESO confirms the new frequencies and reveals the probable presence of yet another pulsational frequency. All five low-amplitude frequencies are statistically significant in the data, but at least one of them (f(5)) suffers from uncertainty due to aliasing. Using colour photometry we find evidence for a radial main frequency (f(1)), while most or all low-amplitude frequencies are likely non-radial. We show that the main frequency of V1162 Ori has variable amplitude and period/phase, the latter is also displayed in the O-C diagram from light extrema. The amplitude variability in our data is cyclic with a period of 282 d and a range of nearly 20 mmag, but earlier amplitude values quoted in the literature cannot be explained by this cyclic variation.

The comparison of the broad-band flux spectra of these host galaxies with the template spectral energy distributions (SEDs) of local starburst galaxies of different morphological types shows that the BVRcIc of the hosts are best fitted by the spectral properties of template SEDs of starburst galaxies and that there is a significant internal extinction in these host galaxies. We derived the absolute magnitudes of the GRB host galaxies making use of SEDs for the starburst galaxies. To create theoretical templates we performed the population synthesis modeling of the continuum spectral energy distribution of the host galaxies of GRB 970508 and GRB 980703 using different extinction laws (Cardelli et al. 1989 and Calzetti et al. 2000) and assuming burst and exponential scenarios of star formation. The comparison of BVRcIc broad-band flux spectra with the local starburst galaxies templates and theoretical templates as well as direct estimates (using Balmer emission lines) of the internal extinction shows that it is likely to be of great importance to take into account effects of the internal extinction in the host galaxies. From the energy distribution in the spectrum of the host galaxy of GRB 991208 and from the intensity of their spectral lines (with allowance for the effects of internal extinction) it follows that this is a GRB galaxy with the highest massive star-formation rate of all known GRB galaxies - up to hundreds of solar masses per year. The reduced luminosity of these dusty galaxies (e.g. for the host of GRB 970508 A(V) similar to 2 mag, for the host of GRB 980703 A(V) similar to 0.6 mag and for the host of GRB 991208 A(V) similar to 2 mag) could explain the observational fact (it results independently from our BVRcIc photometry and from calculated spectral distribution for the subset of galaxies having been observed with the 6-m telescope): none of the observed GRB host galaxies with known distances is brighter than the local galaxies with the luminosity L-* (where L-* is the ""knee"" of the local luminosity function)."

In 6 of these 11 galaxies radio halos were detected at the angular resolution of the current data. In the remaining cases the presence of halo emission could not be proven unambiguously, partly due to relatively low angular resolution. A clear trend was found that galaxies with radio halos are those with the highest far-infrared 60 mum to 100 mum flux ratios. This shows the suitability of high f(60)/f(100) ratios of greater than or equal to0.4 as a reliable tracer of galaxies with high star formation rates and related disk-halo interactions, leading to the presence of extraplanar emission, e.g. from cosmic ray electrons. The measured exponential scale heights of those 6 radio halos that were clearly detected range from about 1.4 to 3.1 kpc. All 4 physically small galaxies in our sample do show extraplanar synchrotron radio emission, indicating that their more shallow gravitational potential compared to normal-sized spirals might facilitate the escape of cosmic-ray electrons from the sites of star formation in their disks. Although the galaxies with the highest energy input rates into the ISM of their disks are those that have the most prominent radio halos, there is no direct relation between the halo scale heights and the energy input rates. Instead, the scale heights of the radio halos are dominated by the energy losses of the cosmic ray electrons on their way out of the galaxy disks."

We have assembled 11 spectra, from GHz radio through GeV gamma -rays, from the time intervals of EGRET observations. Although some of the data have appeared in previous publications, most are new, including data taken during the high states in early 1999 and early 2000. All of the spectra show substantial gamma -ray contribution to the total luminosity of the object; in a high state, the gamma -ray luminosity dominates over that at all other frequencies by a factor of more than 10. There is no clear pattern of time correlation; different bands do not always rise and fall together, even in the optical, X-ray, and gamma -ray bands. The spectra are modeled using a leptonic jet, with combined synchrotron self-Compton plus external Compton gamma -ray production. Spectral variability of 3C 279 is consistent with variations of the bulk Lorentz factor of the jet, accompanied by changes in the spectral shape of the electron distribution. Our modeling results are consistent with the UV spectrum of 3C 279 being dominated by accretion disk radiation during times of low gamma -ray intensity."

Communities representative of Patagonian steppe and marshes were compared with respect to the mycorrhizal status of their species. Most of both native and exotic plant species sampled were arbuscular mycorrhizal (AM). The percentage of species with mycorrhizal association was higher for perennial herbs and shrubs than for annual herbs. The higher ratio of mycorrhizal/nonmycorrhizal (NM) species found for dicotyledons than for monocotyledons, could reflect the presence of a considerable number of NM monocotyledons in the marsh. The mycorrhizal status of plants differed slightly between the steppe and the marsh. In the steppe, native AM species were more frequent than in the marsh. In contrast, in the marsh, the NM species were proportionally more represented than in the steppe. The Juncaceae and Cyperaceae, which include hydrohytic NM plants, accounted for many of these differences. Moreover, the dominant species in the marshes, Juncus arcticus, is a NM species. In the present study, most of species belonging to the same taxonomic family tended to have the same mycorrhizal associations, in agreement with studies on plants from other regions. Exceptions to this general behaviour were observed in the families Cyperaceae, Scrophulariaceae, Berberidaceae and Amaryllidaceae. The most represented families in which mycorrhizal behaviour differed between species of the same family were Asteraceae, Fabaceae and Poaceae. Senecio neaei (Asteraceae) and Boopis australis (Calyceraceae) showed facultative mycorrhizal behaviour."

Lipopolysaccharide profiles and 16S rDNA sequences demonstrated that all twelve acid-tolerant Rhizobium isolates belonged to one species. Furthermore, the group of acid-tolerant Rhizobium isolates was formed by one strain type, since they gave the same plasmid profile as well as the same IS- and ERIC-fingerprints. All acid-tolerant Rhizobium isolates were genetically identical even though they were isolated at very different locations in Argentina. The isolates nodulated a range of Medicago, Melilotus and Trigonella species, and Phaseolus vulgaris, but were weak in nitrogen fixation. M. sativa nodules induced by one of the acid-tolerant rhizobial isolates contained several bacteroids within a vesicle-like structure, in contrast to nodules induced by the reference strain S. meliloti 2011.

Incubation of U937 cells with IFN-gamma sensitized these cells to apoptosis induced by tumor necrosis factor-alpha, agonistic CD95 antibody, and tumor necrosis factor-related apoptosis-inducing ligand, Other human myeloid leukemic cells were also sensitized by IFN-gamma to death receptor-mediated apoptosis. Treatment of U937 cells with IFN-gamma up-regulated the expression of caspase-8 and potently synergized with death receptor ligation in the processing of caspase-8 and BID cleavage. Concomitantly, a marked down-regulation of BCL-2 protein was also observed in cells incubated with IFN-gamma, Furthermore, the caspase-dependent generation of a 23-kDa fragment of BCL-2 protein, the release of cytochrome c from mitochondria and the activation of caspase-9 were also enhanced upon death receptor ligation in IFN-gamma -treated cells. Ectopically expressed Bcl-2 protein inhibited IFN-gamma -induced sensitization to apoptosis. In summary, these results indicate that IFN-gamma sensitizes human myeloid leukemic cells to a death receptor-induced, mitochondria-mediated pathway of apoptosis."

This report describes the initial characterization of the LYT1 gene and the demonstration that the gene product is involved in cell lysis and infectivity. Mutational analysis demonstrated that deletion of LYT1 resulted in attenuation of infection, which was associated with diminished hemolytic activity. Reintroduction of LYT1 restored infectivity in null mutants, confirming the critical role of LYT1 in infection. Additionally, in vitro stage transition experiments with LYT1-deficient lines showed that these parasites converted to extracellular amastigote-like cells and metacyclic trypomastigotes more rapidly than wild-type parasites, suggesting that the diminished infectivity was not a result of the LYT1 deficiency that affected the parasite's ability to complete the life cycle."

The data reported in this paper show that the T. cruzi KMP11 protein is an immunodominant antigen highly recognized by the sera from chagasic and leishmaniasis patients. By the use of amino- and carboxyl-terminal truncated KMP11 recombinant proteins and synthetic peptides, evidence is provided that while the sera from chagasic patients recognize linear peptides the sera from patients with visceral leishmaniasis must be predominantly directed against conformational epitopes. We found that a particular linear determinant, located in the carboxyl-terminal region of the protein, is recognized with high specificity and sensitivity only by sera from Chagas' disease patients, suggesting it could be a good candidate for differential serodiagnosis of Chagas' disease."

The flux decay constant of the optic al afterglow in the R-band is -2.30 +/- 0.07 up to similar to5 days. which is very likely due to the jet effect. and it is followed by a much steeper decay with constant -3.2 +/- 0.2. the fastest one ever seen in a GRB optical afterglow. A negative detection in several all-sky films taken simultaneously with the er ent. that otherwise would have reached naked eye brightness, implies either a previous additional break prior to similar to2 days after the occurrence of the GRB (as expected from the jet effect) or a maximum, as observed in GRB 970508. The existence of a second break might indicate a steepening in the electron spectrum or the superposition of two events, resembling GRB 000301C. Once the afterglow emission vanished, contribution of a bright underlying supernova was found on the basis of the late-time R-band measurements. but the light curve is not sufficiently well sampled to rule out a dust echo explanation. Our redshift determination of z = 0.706 indicates that GRB 991208 is at 3.7 Gpc (for H-0 = 60 km s(-1) Mpc(-1), Omega (0) = 1 and Lambda (0) = 0), implying an isotropic energy release of 1.15 10(53) erg which may. be relaxed by beaming by a factor >10(2). Precise astrometry indicates that the GRB coincides within 0.2"" with the host galaxy, thus supporting a massive star origin. The absolute magnitude of the galaxy is M-B = -18.2, well below the knee of the galaxy luminosity function and we derive a star-forming rate of (11.5 +/- 7.1) M-circle dot yr(-1), which is much larger than the present-day rate in our Galaxy. The quasi simultaneous broad-band photometric spectral energy distribution of the afterglow was determined similar to3.5 day after the burst (Dec. 12.0) implying a cooling frequency ve below the optical band, i.e. supporting a jet model with p = -2.30 as the index of the power-law electron distribution."

Theoretical models suggest that ejection of gas during early phases of stellar evolution is a key mechanism for removing excess angular momentum, thereby allowing material to drift inwards towards the star through an accretion disk(1,2). Such ejections also limit the mass that can be accumulated by the stellar core(1,2). To date, these ejections have been observed to be bipolar and highly collimated, in agreement with theory. Here we report observations at very high angular resolution of the proper motions of an arc of water-vapour masers near a very young, massive star in Cepheus. We rnd that the arc of masers can be fitted to a circle with an accuracy of one part in a thousand, and that the structure is expanding. Only a sphere will always produce a circle in projection, so our observations strongly suggest that the perfectly spherical ejection of material from this star took place about 33 years earlier. The spherical symmetry of the ejecta and its episodic nature are very surprising in the light of present theories."

Setting: Experimental Unit, Virgen de las Nieves University Hospital. Subjects: Seventy-two female CBA/H mice of 20 to 21 g, supplied by the animal center of the Experimental Unit. Intervention: The mice were randomized into three groups of 24, Group 1 (sham) received two intraperitoneal tip) doses of 0.1 mt of phosphate-buffered saline; group 2 (lipopolysaccharide) was injected with 125 mg/kg lipopolysaccharide (Escherichia coil) tip) 24 hrs after 0.1 mt of phosphate-buffered saline; group 3 was pretreated with 80 ng tip) of IL-1 beta per mouse 24 hrs before the endotoxic challenge. Measurements and Main Results:At 1, 2, 4, and 24 hrs after the endotoxic challenge, the concentrations of soluble endothelial/leukocyte adhesion molecule 1 (ELAM-1), intercellular adhesion molecule 1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) were measured in the three groups. There was a significant increase (p < .01) in these concentrations at these times in comparison with the sham group, The use of IL-1<beta> produced a significant decrease (p < .05) in the three molecules among the treated group versus the group submitted only to the challenge; concentrations of ELAM-1 significantly decreased to below those of the sham group, and those of VCAM-1 reduced to levels that did not significantly differ from those of the sham group. Conclusion: Endotoxin administration significantly increases the concentrations of soluble ELAM-1, ICAM-1, and VCAM-1 in mice, Treatment with IL-1<beta> significantly decreases these concentrations, probably attenuating cell injury and organ dysfunction."

A large number of structural components are identified in the nebula: an outer bipolar and an inner shell, two pairs of collimated bipolar structures at different directions, monopolar bow-shock-like structures, and an extended equatorial structure within a halo. The formation of Hu 2-1 appears to be dominated by anisotropic mass ejection during the late-AGB stage of the progenitor and by variable, 'precessing' collimated bipolar outflows during the protoplanetary nebula and/or early planetary nebula phases. Different observational results strongly support the existence of a binary central star in Hu 2-1, among them (1) the observed point-symmetry of the bipolar lobes and inner shell, and the departures from axial symmetry of the bipolar lobes, (2) the off-centre position of the central star, (3) the detection of mass ejection towards the equatorial plane, and (4) the presence of 'precessing' collimated outflows. In addition, (5) an analysis of the kinematics shows that the systemic velocity of the bipolar outflows does not coincide with the systemic velocity of the bipolar shell. We propose that this velocity difference is a direct evidence of orbital motion of the ejection source in a binary system. From a deduced orbital velocity of similar to 10 km s(-1), a semimajor axis of similar to9-27 au and period of similar to 25-80 yr are obtained, assuming a reasonable range of masses. These parameters are used to analyse the formation of Hu 2-1 within current scenarios of planetary nebulae with binary central stars."

By combining our observations at 6 cm with previous data obtained at 3.6 cm, we estimate the spectral indices of the sources in the fields. For 32 of the sources we discriminate the sign of the spectral index and thus, we obtain information about the nature of the emission. For seven outflows (Mon R2E, S287-B, L1654, L483, PV Cephei, L1203, and L1251A) we found at least a central source with an spectral index consistent with thermal free-free emission from thermal radio jets. Multiple sources, separated similar to 10 "", are found near the center of the Mon R2E, S287-B, L1654, and L1251A outflows. In the case of S287-B we found two sources that are valid candidates to drive the S287-B molecular outflow and could be related to the outflow excitation. Under the assumption that the observed emission arises from thermal radio jets, we discuss the mechanism responsible for the ionization and the constraints that introduces on their physical parameters, and we estimate that the flow of ionized material has to originate at a few AU from the exciting star. Most of the remaining, noncentral, sources are characterized by negative spectral indices (alpha < -0.1) and are probably nonthermal background objects unrelated to the studied star-forming regions."

The effect of amendment with exogenous organic matter was also studied. Adsorption kinetic fits an hyperbolic model. MBT adsorption reached an apparent equilibrium within 2 h and followed a second-order reaction. The maximum adsorbed amounts for natural soils ranged from 32 to 145 mug g(-1). Rate constants were considered relatively low (0.27-1.5 x 10(-4) [mug g(-1)](1-n) (s-1)); the slow process was attributed to a combined effect of diffussion and adsorption. MBT adsorption fits the Freundlich model with r values greater than or equal to0.998 at P less than or equal to 0.001 significance levels. K-f and Freundlich exponents (1/n) ranged from 5.3 to 82.1 cm(3) g(-1) and from 0.66 to 0.73, respectively. K-f values for soils with a low organic matter content were lower than that obtained from the only typical allophanic soil derived from volcanic ash under study. Lineal regression analysis between K-f and organic matter content of nonallophanic soils gave a correlation coefficient of 0.980 (P = 0.02). Dispersion of K-d values together with close values of K-OM indicate that organic matter (OM) was the principal component responsible for MBT adsorption in unamended soils. Addition of peat decreased soil pH and increased adsorption capacity for allophanic and nonallophanic soils. Kinetic experiments showed enhancements of X-max values and lower rate constants."

The cohorts of mothers and infants of 1982 and 1993 were studied from the time of delivery. In both years, all mothers identified in the city's maternity hospitals answered a standardised questionnaire and their infants were examined. Over 99% of all children born in the city in each of the 2 years were included in the cohorts. Deaths occurring among these children were monitored prospectively, as well as all hospital admissions in the 1993 cohort. In the 1982 study, attempts were made to locate a 25% sample of the children at the mean age of 12 months using the addresses collected at the hospital (82% of the children were located), and all of the cohort children at the mean age of 20 months and 42 months, through a city census (87% were located in both follow-ups). In the 1993 study, 20% of all children plus all low birthweight infants were sought at 12 months of age, using the addresses collected at the hospital, and 95% were successfully traced. There was a 12% fall in the number of births occurring in 1993 (5304 births), in comparison with 1982 (6011 births), in spite of the increase in the population of reproductive age in the city during the decade. There was a marked difference in maternal height and weight at the beginning of pregnancy, with women giving birth in 1993 being, on average, 3.4 cm taller and 2.5 kg heavier than those who gave birth in 1982. The proportion of preterm babies (<37 weeks), measured by the date of last menstrual period, increased from 5.6% in 1982 to 7.5% in 1993. The median duration of breast feeding increased from 3.1 months in 1982 to 4.0 months in 1993. At 12 months of age, the prevalence of deficit of weight for age decreased from 5.4% in 1982 to 3.7% in 1993. The prevalence of deficit of height for age, however, increased from 5.3% to 6.1%. The perinatal mortality rate dropped 31%, from 32.2 per 1000 births in 1982 to 22.1 deaths per 1000 births in 1993. There was also a marked reduction in the infant mortality rate, from 36.4 per 1000 livebirths in 1982 to 21.1 per 1000 livebirths in 1993. The findings of the study indicate that there were improvements in the decade for most of the indicators evaluated, with the exception of birthweight and gestational age. It appears that improvements in perinatal and infant mortality rates are largely due to improvements in the health care sector."

Study design: Seventeen infants were fed a conventional formula for low birth-weight infants (F), and 17 a formula containing n - 6 and n -3 LCP from purified pig-brain phospholipids (LCP-F). Fourteen infants receiving human milk from a human milk bank were used as a reference (HM). Growth index were measured and blood samples were taken at entry and after 15 days and 30 days of feeding. Results: In infants fed LCP-F the levels of 22:6n - 3 in total plasma lipids and in plasma phospholipids and triglycerides were higher than in infants fed F and closer to the levels of HM group throughout the study. Docosahexaenoic acid concentration in total plasma lipids was 3.46 +/- 0.19 mg/dl in infants fed LCP-F and 2.08 +/- 0.20 in infants fed F after 15 days of feeding (P < 0.001), and 3.83 +/- 0.30 and 2.15 +/- 0.20 in infants fed LCP-F and F respectively, after 30 days of feeding (P < 0.001). The concentration of 20:4n - 6 in the LCP-F was significantly higher than in the F group at 15 and 30 days of feeding. Plasma antioxidant capacity did not differ significantly between the study groups. Conclusion: Feeding low birth-weight infants a formula containing LCP phospholipids results in an increase of n - 3 and n - 6 LCP in plasma towards that of infants fed human milk.

The sequence analysis displayed a 341-amino acid protein of about 37 300 Da molecular mass, corresponding to the subunit of this homotetrameric enzyme; it showed about 80% homology with the other ten higher plant cytosolic FBPases sequenced so far. The enzyme displayed a strong transcriptional expression in green organs (sessile and petioled leaves, stem, pod and grain), and poor expression in root and senescent basal leaves. It is noteworthy the high FBPase transcriptional expression in pod, which displays up to 4-fold higher content of FBPase-specific mRNA than that of root. The mRNA related to cytosolic FBPase was detected after 24 h continuous illumination of 24-h-dark-grown seedlings; this light-induced transcriptional expression is slower than that of chloroplast FBPase, which appears soon after 2 h light. In both cases the corresponding mRNAs disappeared when the light was turned off. The translational expression was also manifested, both as FBPase protein and activity, after 24 h illumination. This delay in the expression of cytosolic FBPase with respect to that of the plastidic enzyme can be interpreted as an indirect effect induced by a metabolite of the photosynthetic carbon pathway, rather than a direct effect of light on the DNA-expression mechanism. Pea cytosolic FBPase was not activated by dithiothreitol, with or without coupling to thioredoxins f or m. The enzyme showed a half-life of 6 h."

In terms of genetic distance Peruvians are closest to Bolivians, which is in agreement with the geographical location and the cultural and anthropological background of the two human groups. Several HLA-B alleles originally described in genetically isolated Amerindian tribes are also present in the sample studied here.

Up to eight optical flashes were recorded with CCD video cameras attached to small telescopes on November 18, 1999. Six impacts were videotaped by at least two independent observers at the same times and lunar locations, which is perhaps the strongest evidence for their collisional nature. The flashes were clearly above the noise and lasted for less than 0.02 s. Although previous observational efforts did not succeed in detecting impact flashes, additional candidates have been reported in the literature. The evidence accumulated so far implies that small telescopes equipped with high speed cameras can be used as a new tool for studying meteoroid streams, sporadic meteoroids, and hypervelocity collisions. In this review we discuss the various intervening parameters for detectability of flashes on the night side of the Moon (geometrical effects, contamination by scattered light from the day side, and properties of the meteoroids such as speed and flux of particles). Particular emphasis is placed on the analysis of the observations in order to derive relevant physical parameters such as luminous efficiencies, impactor masses, and crater sizes. Some of these parameters are of interest for constraining theoretical impact models. From a simple analysis, it is possible to derive the mass distribution of the impactors in the kg range. A more elaborate analysis of the data permits an estimate of the fraction of kinetic energy converted to radiation (luminous efficiency) if the meteoroid flux on the Moon is known. Applied to the 1999 lunar Leonids, these methods yield a mass index of 1.6 +/- 0.1 and luminous efficiencies of 2 x 10(-3) with an uncertainty of about one order of magnitude. Predictions of visibility of the major annual meteor showers are given for the next few years. These include the forthcoming 2001 Leonid return, for which we estimate detection rates in the visible."

The two components of the radio source are separated by 0"".3, corresponding to a projected separation of 65 AU for a distance of 220 pc. We propose that the radio sources trace the components of a binary system. The observed separation implies a lower limit of similar to 135 yr for the orbital period, for a binary system with a total mass of 2 M-.. We suggest that, as in other pre-main-sequence binaries, the two components of the system could be in different evolutionary stages and/or suffer from different extinction, with the more extincted object being associated with the previously reported millimeter source, while the other component would correspond to the visible star SVS 13. Since an increase in the optical/near-infrared brightness of the SVS 13 star was observed around 1990, we speculate that such flux variations could be due to the reappearance of the optical component previously occulted by the circumstellar envelope/disk of dust associated with the millimeter component. The observed separation implies a radius of similar to 60 AU for the presumed dust envelope and suggests an orbital period of similar to 1700 yr and a duration of the occultation of similar to 185 yr. We expect that other subarcsecond binary systems, which remain unresolved, could present an anomalous behavior that may be explained by assuming the presence of a binary system whose components are in different evolutionary stages and/or suffer from different extinction."

Several playa lakes from the San Francisco basin (26 degrees 56' S; 68 degrees 08' W, 3800-3900 m a.s.l.) show evidence of a recent raise in the watertable that led to modern deposition of carbonate and diatomaceous muds. A 2 m - long core from El Peinado Lake (26 degrees 29' 59 "" S, 68 degrees 05' 32 "" W, 3820 m a.s.l.) consists of calcitic crusts (unit 3), overlaid by an alternation of macrophyte-rich and travertine clast- rich, laminated muds (unit 2), and topped by travertine facies (unit 1). This sedimentary sequence illustrates a paleohydrological evolution from a subaerial exposure (unit 3) to a high lake stand (unit 2), and a subsequent smaller decrease in lake level (unit 1). The delta C-13(organic matter) record also reflects the lake transgression between units 3 and 2. Although there is a general positive correlation between delta O-18(carbonate) and salinity proxies (Na, Li and B content), the large data dispersion indicates that other factors besides evaporation effects control chemical and isotopic composition of lakewater. Consequently, the oxygen isotopic composition cannot be interpreted exclusively as an indicator of salinity or evaporation ratio. The degassing of CO2 during groundwater discharge can explain the enriched delta C-13 values for primary carbonates precipitated. The carbon budget in these high altitude, saline lakes seems to be controlled by physical rather than biological processes. The Altiplano saline lakes contain records of environmental and climatic change, although accurate C-14 dating of these lacustrine sediments is hindered by the scarcity of terrestrial organic material, and the large reservoir effects. Sedimentologic evidence, a Pb-210-based chronology, and a preliminary U/Th chronology indicate a very large reservoir effect in El Peinado, likely as a result of old groundwaters and large contributions of volcanic and geothermal C-14-free CO2 to the lake system. Alternative chronologies are needed to place these paleorecords in a reliable chronological framework. A period of increased water balance in the San Francisco basin ended at about 1660 +/- 82 yr B.P. (calendar yr U/Th age), and would correlates with the humid phase between 3000 and 1800 yr B.P detected in other sites of the southern Altiplano. Both, Pb-210 and preliminary U/Th dating favor a younger age for the paleohydrological changes in El Peinado. The arid period reflected by subaerial exposure and low lake levels in unit 3 would have ended with a large increase in effective moisture during the late 17th century. The increased lake level during deposition of unit 2 would represent the period between AD1650 - 1900, synchronous to the Little Ice Age. This chronological framework is coherent with other regional records that show an abrupt transition from more arid to more humid conditions in the early 17th century, and a change to modern conditions in the late 19th century. Although there are local differences, the Little Ice Age stands as a significant climatic event in the Andean Altiplano."

Quantitation of pesticides is made by HPLC and the R/S ratio by GC-MS. The inactive S-enantiomer from the racemic forms persists longer than the R-forms in silt and sandy loam soils, but for shorter time in the clay loam soil. The pure R-enantiomers, both for MCPP and DCPP, after incubation in soil, are partially converted into their S-forms. In all cases, the dissipation of racemic and pure enatiomeric forms is lower in the clay loam soil than in the silt and sandy loam soils. The R-forms' peristence, in the three soils, is approximately two times lower when they are incubated alone than when they are incubated as racemic compounds. When peat is added, the persistence of these herbicides in the silt and sandy loam soils increases, while in the clay loam soil it decreases. Besides, in the clay loam soil, the enantiomeric ratio (ER) changes from its S-preferential degradation to a preferential degradation of its R-form, so an increase in the persistence of the inactive S-form occurs.

It is shown that the observational data are consistent with luminous efficiencies of 2 x 10(-3) in the wavelength range of 400-900 nm with an uncertainty of about 1 order of magnitude. This experimental value of eta is significantly larger than previous estimates for meteoroids of asteroidal composition based on numerical calculations and scaling laws from laboratory collisions. According to our results, the luminous efficiency might vary with mass, i.e., the smaller impactors converting less kinetic energy into light and vice versa. A comparison with recent numerical simulations for meteoroids of cometary composition is also carried out."

High-resolution long-slit spectroscopy is used to track the impact from massive stars, while Hubble Space Telescope archive data are used to display the asymmetry of the nebula. NGC 604 is found to be a collection of photoionized filaments and sections of shells that are in direct contact with the thermalized matter ejected by the massive stars.

Such PGP activity was investigated for both a wild type strain and its genetically modified (GM) derivative, which had an enhanced biofertilizer capability. The PGP effect of these rhizobial strains was tested in interaction with two arbuscular-mycorrhizal (AM) fungi: G. mosseae or G. intraradices on lettuce (Lactuca sativa L.) plants. Both rhizobial strains were efficient in increasing lettuce biomass and also induced modifications on root morphology, particularly in mycorrhizal plants; thus these strains behave as plant growth promoting rhizobacteria. In non-mycorrhizal plants, both strains exhibited a similar growth promoting effect on lettuce. However, both rhizobial strains differed in mycorrhizal plants with regard to (i) biomass production, (ii) the length of axis and lateral roots, and (iii) the number of lateral roots formed; effects which were, in turn, affected by the AM fungus involved. Microbial treatments were more effective on root growth and morphology at earlier developmental stages (20 days of plant growth) but, in a later stage (after 40 days), the microbial effects were more relevant at increasing plant biomass. The interaction between the GM rhizobial strain and G. mosseae produced the highest growth promoting effect (476% over control), in spite of the fact that G. intraradices showed a quicker and higher colonization ability than G. mosseae. Microbial interactions inducing PGP effects did not benefit AM colonization nor the succinate dehydrogenase activity in the AM fungal mycelium. Irrespective of the underlying mechanisms, which are being now investigated, the interactions between rhizobial strains, as free-living saprophs, and AM fungi are noteworthy, and depend on the microbial genotype involved.

The observed light curves were fitted with a power-law decay for the optical transient (OT), plus an additional component that was treated in two different ways. First, the additional component was assumed to be an underlying galaxy of constant brightness. The resulting slope of the decay is 0.97(-0.02)(+0.05), and the magnitudes of the underlying galaxy are V = 22.3 +/- 0.05, R = 21.75 +/- 0.05, and I = 21.35 +/- 0.05. Second, the additional component was assumed to be a galaxy plus an underlying supernova with a time-variable brightness identical to that of GRB 980425, appropriately scaled to the redshift of GRB 990712. The resulting slope of the decay is similar, but the goodness of fit is worse, which would imply that either this GRB is not associated with an underlying supernova or the underlying supernova is much fainter than the supernova associated with GRB 980425. The galaxy in this case is fainter: V = 22.7 +/- 0.05, R = 22.25 +/- 0.05, and I = 22.15 +/- 0.05, and the OT plus the underlying supernova at a given time is brighter. Measurements of the brightnesses of the OT and the galaxy by late-time Hubble Space Telescope observation and ground-based observations can thus assess the presence of an underlying supernova."

The aim of that comparative analysis is to find the differential properties that could be directly connected with the phenomenon of nuclear activity. We stress the importance of using isolated objects for that purpose. Our study shows that both sets of galaxies are similar in their global properties: they define the same Kormendy relation, their disk components share the same properties, the bulge and disk scale lengths are correlated in a similar way, bar strengths and lengths are similar for primary bars. Our results therefore indicate that hosts of isolated Seyfert galaxies have bulge and disk properties comparable to those of isolated non active spirals. Central colors (the innermost 200 pc) of active galaxies are redder than the centers of non active spirals, most probably due to AGN light being re-emitted by the hot dust and/or due to circumnuclear star formation, through the contribution of giants/supergiants. Central to our analysis is the study of the possible connection between bars and similar non axisymmetric structures with the nuclear fuelling. We note that only one of the Seyfert galaxies in our sample, namely ESO 139-12, does not present a primary bar. But bars are equally present in active and control objects. The same applies to secondary bars. Not all the active galaxies we have observed have them, and some control galaxies also present such central structures. Secondary central elongations (associated with secondary bars, lenses, rings or disks) may be somewhat different,, but this result should be confirmed with larger samples. We note that numerical models indicate that such secondary bars are not strictly necessary to feed the central engine when a primary bar is present. Our results show that down to scales of 100-300 pc, there are no evident differences between active and non active spiral galaxies."

Host plants: maize (Zea mays L.), sorghum (Sorghum vulgare L.), lettuce ( Lactuca sativa L.), tomato (Lycopersicum esculentum L.), wheat (Triticum vulgare L), lentil (Ervum lens L.) and pea (Pisum sativum L.), the AM fungi: Glomus mosseae, G. fasciculatum, G. intraradices, G. clarum, and G. deserticola and the carriers for F. oxysporum inoculum: aqueous solution, thin agar slices, and pellets of agar and alginate were tested under greenhouse conditions. Greatest plant growth and AM colonization responses in sterilized and unsterilized soils were observed with pea, Glomus deserticola and sodium alginate pellets as the carrier for F. oxysporum inoculum. Under field conditions, adding F. oxysporum increased the survival of transplanted pea, possibly through a beneficial effect on AM fungi. Application of F. oxysporum increased shoot dry matter, N and P concentrations of pea and sorghum plants, and the level of AM colonization attained by indigenous or introduced AM fungi. These parameters were similar in plants inoculated with either G. deserticola or with the indigenous AM fungi. Application of the saprophytic fungus increased the number of propagules of AM fungi in field plots in which pea was grown, but this increase was not sufficient to increase AM colonization of sorghum after the pea crop."

This implies the existence of, at least, two different kinematic groups defining the GB system. We also model the evolution of a supershell in the solar neighborhood, and obtain a fit to the shape and kinematics of the gas in GB. Assuming that the expanding shell is also forming stars, we obtain the corresponding velocity fields for the shell and its newly formed stars.

The critical points of the potential energy surface for the OH addition to toluene are determined, and rate-equilibrium relationships are discussed. A stable structure corresponding to a prereactive complex which is formed when the OH radical is at about 2.5 Angstrom from toluene is obtained. The existence of this loosely bound system is necessary to explain the experimentally observed negative activation energy. The geometry of transition states and products are determined for addition at different positions in the ring, including the ipso position, which has not been considered in previous works. Energy results at the MP4 and coupled cluster levels calculated at the optimized MP2 and B3LYP geometries confirm that the ipso adduct is more stable than the ortho adduct by about 0.5 kcal/mol.

In contrast, the translational expression of Trx f was low in this organ, The high FBPase activity in immature seeds, and the low activity of leaves, must be related to high starch synthesis in the first, and with high sucrose formation in the second. The transcriptional expression of FBPase and NADP(+)-MDH, and to a lesser extent that of Trxs f and m, was inhibited under low irradiance in plants grown under both normal and high temperatures. Pea plants grown at low temperature displayed a high level of mRNAs for Trxs and their targets, especially when the growth was carried out at low light. To a lesser extent, similar behaviour was observed at the protein level, Chloroplasts of mesophyll leaf cells of pea plants grown under saturating light, or under sub-saturating continuous irradiance, showed broken envelopes, distorted structural elements and disorganized starch grains, as a consequence of a photobleaching process and high starch accumulation."

Over 7500 microearthquakes and earthquakes from 1985 to 1994 were analyzed to test that its spatial and temporal distributions are such that can be described by a Levy flight with anomalous diffusion (in this case in a subdiffusive regime). Earthquake behavior is well described through Levy flights and Levy distribution functions such as results show.

A model of the catalytic site of the protein has been built using two segments of three and four amino acids, respectively, which include four of the most important residues of the enzyme. The mechanism is based on that proposed by Strynadka et al, in 1992 (Strynadka et al,, Nature 359 (1992) 700-705). The results confirm that Lys-73 is expected to be unprotonated in the wild-type enzyme, and therefore acts as a general base in the acylation step of the reaction, Previous contradictory results are discussed, and a new proton transfer pathway from Lys-73 to p-lactam nitrogen is proposed.

The discovery of a pair of symmetric low-excitation bow-shocks, separated by 4', and forming a highly collimated bipolar outflow, is presented. The bow-shocks are emitting in [O III] and present the ionization structure expected from working surfaces of collimated jets, pointing out that these structures are tracing regions with shocked gas at high velocities (> 100 km s(-1)). In addition, an internal bipolar outflow (60 "" x 30 "") and an apparent off-center semi-circular shell (size approximate to 110 "") are also detected.

Observations at four epochs were obtained, and images were produced at three of these. One of these three epochs was when the source was near the minimum flux density of the ESE, the other two were as the flux density of the source was returning to its nominal value. The fourth epoch was at the maximum flux density during the egress from the ESE, but the VLBI observations had too few stations to produce an image. During the event the source consisted of a dominant, compact component, essentially identical to the structure seen outside the event. However, the source's diameter increased slightly at 13 cm, from near 0.6 mas outside the ESE to near 1 mas during the ESE. An increase in the source's diameter is inconsistent with a simple refractive model in which a smooth refractive lens drifted across the line of sight to PKS 1741-038. We also see no evidence for ESE-induced substructure within the source or the formation of multiple images, as would occur in a strongly refractive lens. However, a model in which the decrease in flux density during the ESE occurs solely because of stochastic broadening within the lens requires a larger broadening diameter during the event than is observed. Thus, the ESE toward PKS 1741-038 involved both stochastic broadening and refractive defocusing within the lens. If the structure responsible for the ESE has a size of order I AU, the level of scattering within an ESE lens may be a factor of 10(7) larger than that in the ambient medium. A filamentary structure could reduce the difference between the strength of scattering in the lens and ambient medium, but there is no evidence for a refractively induced elongation of the source. We conclude that, if ESEs arise from filamentary structures, they occur when the filamentary structures are seen lengthwise. We are able to predict the amount of pulse broadening that would result from a comparable lens passing in front of a pulsar. The pulse broadening would be no more than 1.1 mu s, consistent with the lack of pulse broadening detected during ESEs toward the pulsars PSR B1937+21 and PSR J1643-1224. The line of sight toward PKS 1741-038 is consistent with a turbulent origin for the structures responsible for ESEs. The source PKS 1741-038 lies near the radio Loop I and is seen through a local minimum in 100 mu m emission."

These observations show a great wealth of structures. The bright central nebula is surrounded by an attached shell and a detached outer halo. Both the inner and intermediate shells can be described as ellipsoids with similar major to minor axial ratios, but different spatial orientations. The kinematical ages of the intermediate shell and halo are 4800 and 28 000 yr, respectively. The intershell time lapse is in good agreement with the evolutionary interpulse time lapse. A highly collimated outflow is observed to protrude from the tips of the major axis of the inner nebula and impact on the outer edge of the intermediate shell. Kinematics and excitation of this outflow provide conclusive evidence that it is deflected during the interaction with the outer edge of the intermediate shell. At the same time, both the kinematics and the morphology of the intermediate shell appear to be affected by this interaction."

There are several paths from a conventional critical point to SOC. They begin with an absorbing-state phase transition (directed percolation is a familiar example), and impose supervision or driving on the system; two commonly used methods are extremal dynamics, and driving at a rate approaching zero. We illustrate this in sandpiles, where SOC is a consequence of slow driving in a system exhibiting an absorbing-state phase transition with a conserved density. Other paths to SOC, in driven interfaces, the Bak-Sneppen model, and self-organized directed percolation, are also examined. We review the status of experimental realizations of SOC in Light of these observations."

The presence of individual frequencies is confirmed by intercomparing four subsets of this data set, however, the uncertainties in data coming from the sparse nights and low signal weaken the conclusion on some results. The entire data base is then used to resolve closely spaced peaks. Twelve frequencies are indentified using this process. Further multisite observations are recommended to confirm the present frequency solution. Two periods, with a high probability of being real, are found in the low frequency domain. They are suggested to arise from binarity or g modes, as in gamma Dor stars. Single unusual cycles, possessing large amplitude, or displaying asymmetry, have been localized. A coherent frequency at 29.83 c/d with variable amplitude was found.

The difference in length between the two gene units is due to the presence of a short interspersed nucleotide element (SINE)-like DNA sequence inserted at the 3' end of some of these units. Southern, northern and chromosomal blot analysis of a Brazilian Y strain and six Colombian strains demonstrated the existence of polymorphisms regarding the relative copy number of the H2A gene units, the relative abundance of the H2A transcripts and their chromosomal location. These results show the existence of a dynamic organization in the H2A loci among T, cruzi strains in which a SINE-like sequence may be involved and support the fact that T. cruzi has a high degree of plasticity in its genome.

Several emission lines are identified, including the He II 4686 line and strong [N II]6548, 6583 and [O III]4959, 5007 emissions [I([N II])/I(H alpha) similar or equal to 5.5, I([O III])/I(H beta) similar or equal to 30]. A systemic velocity V-LSR = 10 +/- 2 km s(-1) for K3-35 is obtained from the optical emission lines, Two different kinematic components are identified in the nebula. One of them is probably related to the elliptical envelope previously observed. The second component exhibits systematic changes of the radial velocity with position, and a relatively small velocity width. This component may be attributed to the precessing jet-like outflows previously identified. The R and I images and the deduced R - I colour map strongly support the existence of a dense, partially neutral disc-like region in the equatorial plane of the nebula, which probably represents an equatorial density enhancement in a previously ejected slow wind. Diagnostic diagrams for Line intensity ratios in K 3-35 and collimated components of other planetary nebulae suggest that the emission spectrum of this kind of structure is a combination of radiative and shock excitation, in agreement with recent models of shocks in a strongly photoionized medium."

We use the Sersic law to describe their light profile. The specific entropy (Boltzmann-Gibbs definition) is then calculated supposing that the galaxies behave as spherical, isotropic, one-component systems. We find that, to a good approximation (similar to 10%), both real and virtual galaxies have an almost unique specific entropy. Within this approximation the galaxies are distributed in a thin plane in the space defined by the three Sersic law parameters, which we call the Entropic Plane. A further analysis shows that both real and virtual galaxies are in fact located on a thin line, therefore indicating the existence of another - and yet unknown - physical property, besides the uniqueness of the specific entropy. A more careful examination of the virtual galaxies sample indicates a very small increase of their specific entropy with merging generation. In a hierarchical scenario, this implies a correlation between the specific entropy and the total mass, which is indeed seen in our data. The scatter and tilt of the Entropic Line, defined by Lima Neto et al. (1999a), are reduced when this correlation is taken into account. Although one cannot distinguish between various generations for real galaxies, the distribution of their specific entropy is similar to that in the virtual sample, suggesting that hierarchical merging processes could be an important mechanism in the building of elliptical galaxies."

We find that there is little ongoing star formation inside the bar dominated region of the galaxy, except for the circumnuclear ring at 5 arcsec radius. There is some evidence that this star formation occurs in two modes, in bursts and continuously, along the ring and inwards, towards the nucleus. The equivalent width of the Call triplet absorption lines show that, in the metal rich central region, the continuum is dominated by a population of red supergiants, while red giants dominate outside. The gaseous kinematics along three slit position angles, and the comparison with the stellar kinematics, suggest the existence of a hierarchy of disks within disks, whose dynamics are decoupled at the two inner Linblad resonances (ILR), that we find to be located at 180 pc and at 1100 pc. This is supported by the structure seen in the high resolution HST images. The nucleus is spatially resolved in the emission line ratio [NII]/H alpha, and in the FWHM of the emission lines, within a radius of 1.5"", just inside the innermost ILR. Outside the iILR, the stellar CaT velocity profile is resolved into two different components, associated with the bar and the disk. Several results indicate that this is a dynamically old system: the little ongoing star formation inside the bar dominated part of the galaxy, the very large relative amount of molecular to total mass within the inner 6 arcsec radius, similar to 25%, and the geometry of the circumnuclear ring that leads the stellar bar at a position angle greater than 90 degrees. It is thus possible that a nuclear bar has existed in NGC 6951 that drove the gas towards the nucleus, as in the bars within bars scenario, but that this bar has already dissolved by the gas accumulated within the circumnuclear region. We discuss the possibility that the kinematical component inside the ilLR could be due to a nuclear outflow produced by the combined effects of SN and SN remnants, or to a nuclear disk, as in the disk within disk scenario that we propose fur the fueling of the AGN in NGC 6951."

The dearest results appear in apical, but also in middle leaves. Enzyme activites of FBPase and NADP-MDH were lowest just before flowering. In the case of FBPase this was probably a mechanism to facilitate triose-phosphate export to the cytosol for sucrose synthesis. The likely function of NADP-MDH is to supply the cytosol, via the malate translocator, with the NAD(P)H necessary for UTP regeneration in the sucrose biosynthetic pathway. Both the F-v/F(m)ratio and the net photosynthetic rate (IRGA) decreased at saturating irradiance (16 h photoperiod) and under sub-saturating continuous light. However, the F-v/F-m quotient recovered to normal values after several days adaptation to high light. A similar recovery was also observed in net photosynthesis, although normal levels were never obtained. Under light-stress conditions the concentration of Trxs f and m, and of the targets FBPase and NADP-MDH, were somewhat lower than those of unstressed plants. Even though the levels of the corresponding transcripts (mRNAs) are similar in upper leaves from control and light-stressed plants, those of the middle and basal leaves from plants grown under high light were substantially higher than those of the control plants. In addition to the well-documented transcriptional regulation of nuclear-coded chloroplast proteins, these results seem to indicate the existence of an additional post-transcriptional control."

The majority of these sources, at least 26 of them, are believed to be associated with young objects in the cloud. Among these sources are found candidates to power all the CO outflows observed in the region. For the first time, we detect at centimeter wavelengths counterparts to the young objects IRAS 2A, IRAS 2B, ASR 51, ASR 7, MMS 2, and IRAS 4C, and to the foreground G2 IV star BD +30 degrees 547. There is a strong correlation between the far-infrared and millimeter sources reported previously and the centimeter sources discussed here. Most likely, this correlation results from the fact that young embedded stars systematically have ionized outflows. Under these assumptions, the far-infrared and millimeter emission will originate from dust heated in the surroundings of the star, while the centimeter emission will come from the ionized flow. However, in two of the sources detected, the centimeter emission appears to have a significant contribution from heated dust. Two of the detected sources are time-variable, circularly polarized sources, and one of them is associated with a previously known T Tauri star. The results of our study suggest that sensitive radio continuum studies of other active star-forming regions could reveal a similar diversity of centimeter wavelength sources."

The line broadening observed in the molecular core appears to be a consequence of the interaction between the highly collimated wind from L1448C and the ambient molecular gas. The ammonia line emission shows a velocity gradient in a direction perpendicular to the outflow axis, which is consistent with rotation in a circumstellar structure. In addition, there is also evidence of a velocity gradient along the outflow axis, suggesting that the ammonia line emission could be tracing a self-gravitating, thick, disklike structure around L1448C, which appears to be rotating and contracting. We also detect ammonia emission associated with IRS 3, the infrared source about 75"" northwest of L1448C. This emission presents a wedgelike morphology pointing away from L1448C. We propose that this ammonia structure traces the region where the leading head of the L1448C near-infrared H-2 jet is carving a cavity in the northern molecular core, or alternatively, where the near-infrared H-2 jet is being bent to the west by the northern high-density core. In addition, an anticorrelation between the ammonia and H-2 line emissions is found. The near-infrared H-2 line emission is clearly seen in the relatively low density gap between the northern (IRS 3) and southern (L1448C) molecular cores, while the high-density molecular gas surrounding L1448C completely obscures this young stellar object and its counterjet at optical and near-infrared wavelengths."

Most of the galaxies can be considered ""pure"" Liners on the basis of the Veilleux & Osterbrock (1987) classification as suggested by Ho, Filippenko, & Sargent (1997). However, a considerable number of transition (Liners-HII or Liners-Starburst) objects are also included. One of the open questions, is whether Liners should be considered as a class of galaxies (like Seyfert galaxies for instance) or rather, as an heterogeneous group Of objects. We believe the study of Liners as a group is very interesting, precisely because they very likely represent a transition between non-thermal and starburst activity, and probably also between ""active"" and ""non- active"" galaxies. This catalog may be used as a basis for statistical research. A preliminary discussion of the main statistical properties of Liners, in the range from radio to X-ray frequencies, is given here."

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY		English	Article						"galaxies : clusters : individual : Coma; galaxies : clusters : individual : Abell 85; galaxies : distances and redshifts; galaxies : elliptical and lenticular, cD; galaxies : fundamental parameters; distance scale"	BRIGHTEST CLUSTER MEMBERS; COMA CLUSTER; VIOLENT RELAXATION; FUNDAMENTAL PLANE; SURFACE BRIGHTNESS; STELLAR-SYSTEMS; STATISTICAL-MECHANICS; PHOTOMETRIC CATALOG; LUMINOSITY-PROFILE; CENTRAL REGIONS	"Dynamical systems in equilibrium have a stationary entropy; we suggest that elliptical galaxies, as stellar systems in a stage of quasi-equilibrium, may have in principle a unique specific entropy. This uniqueness, a priori unknown, should be reflected in correlations between the fundamental parameters describing the mass (light) distribution in galaxies. Following recent photometrical work on elliptical galaxies by Caon et al., Graham & Colless and Prugniel & Simien, we use the Sersic law to describe the light profile and an analytical approximation to its three-dimensional deprojection. The specific entropy is then calculated, supposing that the galaxy behaves as a spherical, isotropic, one-component system in hydrostatic equilibrium, obeying the ideal-gas equations of state. We predict a relation between the three parameters of the Sersic law linked to the specific entropy, defining a surface in the parameter space, an 'Entropic Plane', by analogy with the well-known Fundamental Plane. We have analysed elliptical galaxies in two rich clusters of galaxies (Coma and ABCG 85) and a group of galaxies (associated with NGC 4839, near Coma). We show that, for a given cluster, the galaxies follow closely a relation predicted by the constant specific entropy hypothesis with a typical dispersion (one standard deviation) of 9.5 per cent around the mean value of the specific entropy. Moreover, assuming that the specific entropy is also the same for galaxies of different clusters, we are able to derive relative distances between Coma, ABGC 85, and the group of NGC 4839, If the errors are due only to the determination of the specific entropy (about 10 per cent), then the error in the relative distance determination should be less than 20 per cent for rich clusters. We suggest that the unique specific entropy may provide a physical explanation for the distance indicators based on the Sersic profile put forward by Young & Currie and recently discussed by Binggeli & Jerjen."

In addition, VLA-DnC lambda 3.6-cm continuum observations are presented, This material allows one to explore in unprecedented detail the morphology and kinematics of this PN, The morphology of this object is complex given the highly filamentary structure of the envelope, which is confirmed to possess a low mass, The halo has a high expansion velocity that yields incompatible kinematic and evolutionary ages, unless previous acceleration of the nebular expansion is considered. However, the most remarkable result from the present observations is the detection of a bipolar outflow in NGC 4361, which is unexpected in a PN with a Population II low-mass-core progenitor. It is shown that shocks resulting from the interaction of the bipolar outflow with the outer shell are able to provide an additional heating source in this nebula."

There were 48 treatments, altogether, 24 with chlorsulfuron and 24 with glyphosate. Each set of 24 was designed as 2 x 3 x 4 factorial with 1) plus or minus Glomus mosseae, 2) soybean alone, weed alone or soybean plus weed combination, 3) herbicide applied at the rates 0, 0.1, 0.5 and 1 x the field recommendation dose. The shoot dry mass of AM soybean treated with low doses of herbicides, when grown together with B. campestris or S. halepensis, but not when grown alone, was increased. This fact together with the absence of an increase in plant dry mass in intercropped non-AM soybean plants, suggest that the AM fungus mediates nutrient transfer from weeds to soybean. Neither herbicide affected AM colonization of plants except when glyphosate was applied at field recommendation dose to the weed S. halepensis grown as an intercrop. The most beneficial effect of G. mosseae on soybean was found when chlorsulfuron and glyphosate were applied at low doses, but this beneficial effect disappeared when the herbicides were applied at high doses."

Multilocus enzyme electrophoresis analysis of 39 isolates determined 11 different electrophoretic types, clustered into three main genetic groups. Genetic distances between groups were above 0.8. Five different 16S rRNA gene alleles were identified in this population, corresponding to previously described rhizobial species, Rhizobium etli, Rhizobium fredii, Rhizobium gallicum, Rhizobium giardinii and Rhizobium leguminosarum. Using R. etli strain CFN42 nifH and nodB genes as hybridization probes, identical restriction fragment length polymorphism profiles were found among isolates belonging to four different 16S rRNA gene species, indicative of interspecific gene transfer. Most of the bean-nodulating strains carried three copies of nifH and strongly hybridized to the nodB gene of R. etli CFN42, suggesting that their symbiotic plasmid genes are organized similarly. Combined data from multilocus enzyme electrophoresis and 16S allele characterization indicate that more than five bacterial species compose this rhizobial population, as almost identical 16S rDNA alleles were identified in isolates belonging to deeply divergent multilocus enzyme electrophoresis lineages.

Biological effects, as well as variations in carbon source inputs, and in the exchange rate with atmospheric CO2, are commonly considered the main controls on the carbon isotope values of authigenic lacustrine carbonate. We present sedimentological and geochemical evidence that favors physical processes - evaporation effects and CO2-degassing - as major controls on C-13 enrichment. We propose that large enrichments may result from the non-equilibrium gas-transfer isotope fractionation during CO2-degassing from thermal springs and evaporation effects in arid environments. The dilution effect by large quantities of C-14-free CO2 hinders accurate C-14 chronology of these lake records based on lacustrine organic matter and aquatic plants. Our results indicate that geothermal and volcanic CO2 sources in lake basins located in volcanic settings, and physical fractionation may have a greater significance than commonly accepted to explain lacustrine carbon isotope records.

The resulting vertex deviation for the whole sample of 252 stars is l(nu) similar to -64 degrees +/- 20 degrees, and this value is modified to l(nu) = 22 degrees +/- 8 degrees when the members of the Pleiades moving group are removed from the sample. This implies the existence of, at least, two different kinematic groups defining the GB system. We also model the evolution of a supershell in the solar neighborhood and obtain a fit to the shape and kinematics of the gas in the GB. Assuming that the expanding shell is also forming stars, we obtain the corresponding velocity fields for the shell and its newly formed stars. The average vertex deviation value resulting from these models for the new stars (assuming different velocity dispersion values and cutoff distances) is l(nu) similar or equal to 20 degrees and is consistent with the observed value when the Pleiades moving group members are excluded from the GB."

Emission is detected in the main hyperfine line of the first three transitions. The NH3(2, 2) emission shows a non-uniform 'ring' structure, which is more extended (3 arcsec) and intense than the emission seen in the (1, 1) and (3, 3) lines. A rotational temperature of similar to 30-50 K and a lower limit to the mass of similar to 1 (X-NH3/10(-8))(-1) M. are derived for the ring structure, The spatio-kinematical distribution of the NH3 emission does not seem to be consistent with a simple circumstellar disc around the HW 2 thermal biconical radio jet. We suggest that it represents the remnant of the parental core from which both the inner 300-au (0.4 arcsec) disc, traced by the water maser spots previously found in the region, and the central object have formed. The complex velocity field of this core is probably produced from bound motions (similar to those of the inner disc) and from interaction with outflowing material."

As a consequence of this interaction, the elliptical shell has been broken up, and in this process parts of the shell have been accelerated, while the collimated outflow has been slowed down and/or deflected, These results strengthen the notion that collimated outflows are common in planetary nebulae and may play an important role in shaping the nebular shells.

The leaching patterns could be related to variation in the soil texture and diffusion processes of the herbicides into micropores within the walls of conducting pore. The leaching rate in the amended soil columns decreased with the addition of organic matter. The breakthrough curves (BTC) of these herbicides in the leachates of the amended soil columns were wider and more diffused than the ETC obtained for the corresponding unamended soil.

At 153 centers in 34 countries, 1908 otherwise healthy, postmenopausal women with lumbar spine BMD 2 standard deviations or more below the premenopausal adult mean were randomly assigned to receive oral alendronate 10 mg (n = 950) or placebo (n = 958) once daily for 1 year. All patients received 500 mg elemental calcium daily. Baseline characteristics of patients in the two treatment groups were similar. At 12 months, mean increases in BMD were significantly (p less than or equal to 0.001) greater in the alendronate than the placebo group by 4.9% (95% confidence interval 4.6% to 5.2%) at the lumbar spine, 2.4% (2.0% to 2.8%) at the femoral neck, 3.6% (3.2% to 4.1%) at the trochanter and 3.0% (2.6% to 3.4%) for the total hip. The incidence of nonvertebral fractures was significantly lower in the alendronate than the placebo group (19 vs 37 patients with fractures), representing a 47% risk reduction for nonvertebral fracture for alendronate-treated patients (95% confidence interval 10% to 70%; p = 0.021). Incidences of adverse events, including upper gastrointestinal adverse events, were similar in the two groups. Therefore, for postmenopausal women with low bone mass, alendronate is well tolerated and produces significant, progressive increases in BMD at the lumbar spine and hip in addition to significant reduction in the risk of nonvertebral fracture."

The lambda 3.6 cm continuum emission is detected over a region of similar or equal to 65"" x 40"", similar in extent to the optical emission. Physical parameters of the nebula have been derived for the region in which the recombination lines were detected. From the line to continuum ratio, an electron temperature of similar or equal to 16,000 K and a single ionized helium abundance Y+ similar or equal to 0.14 are obtained. A relative extinction map of NGC 2440 has also been obtained from the ratio of the lambda 3.6 cm continuum acid Ha images. A higher relative extinction in the central region traces the dense and dusty environment of an apparent central ""toroid."" The velocity field obtained from the H92a line suggests that the central toroidal structure has a distorted, noncircular shape.

To investigate whether these pseudotyped, pantropic vectors can mediate gene transfer and;expression in E. histolytica, we constructed a retroviral vector, in which a hygromycin phosphotransferase is expressed from the E. histolytica actin promoter. Data confirm the infection, integration, and expression of a foreign gene mediated by the provirus. To our knowledge, this is the most evolutionarily distant example of successful integration and expression of a mammalian retrovirus.

The continuum observations, cross-calibrated with the H2O maser emission, provide information of the thermal jet of this young massive star with unprecedented angular resolution and fidelity. We find that the jet is already collimated on scales smaller than 100 AU. The analysis of the new 1.3 cm data and of previously obtained 3.6 cm data show that the source has the frequency dependences in major axis and flux density that characterize biconical jets. In particular, we find theta(maj) proportional to nu(-0.7+/-0.1) and S-nu proportional to nu(0.8+/-0.1) An improved determination of the mass loss rate in ionized gas, (M) over dot(ion) similar or equal to 9 x 10(-7) M. yr(-1), is provided with these new observations. As it was known from previous studies, the H2O maser emission does not coincide with the thermal jet but with a faint source of radio continuum emission displaced by similar to 7 "" to the northeast of the thermal jet. The H2O masers appear in two compact clusters separated by similar to 20 mas. One of the clusters is formed by spots in a linear geometry. The kinematics of these maser spots and their large blueshift with respect to the radial velocity of the parental molecular cloud suggest that they trace material accelerated by outflow phenomena, instead of a possible disk."

The HCO+ line shows emission up to velocities of similar to 50 km s(-1) relative to the ambient cloud velocity. The spatial distribution of the high-velocity gas is bipolar, centered on HW2, and extends for similar to 1' along P.A. = 55 degrees-60 degrees. The orientation of this molecular outflow is very similar to that of the radio jet and CO emission associated with HW2. This confirms that current mass loss from HW2 takes place in the northeast-southwest direction. The momentum rate of the HCO+ outflow is 1.3 x 10(-2) M-. km s(-1) yr(-1), 20 times larger than that of the ionized jet from HW2, suggesting that the jet could be largely neutral. Peaks of HCO+ emission coincide with some of the radio-continuum sources in the region, consistent with outflow-ambient gas interaction. Multiple episodes of outflow activity from either one precessing source or a number of powering sources would explain the detection of moderate-velocity HCO+ emission toward the HW7 chain of sources. The continuum emission at 3.4 mm is strongly peaked toward HW2, confirming that this is the most likely powering source for the outflow. The SiO emission is barely elongated along P.A. = -33 degrees, i.e., almost perpendicular to the HCO+ outflow. A velocity trend consistent with a gradient of similar to 31 km s(-1) over 2 "" is detected along the major axis of the SiO structure; these motions could be bound by 200 M-.. Published H2O and CS observations support our suggestion that this represents the outer, similar to 750 AU radius, part of a circumstellar disk, although further observations are needed to confirm this interpretation."

Considerable variation in the reproducibility and ri liability of these tests has been reported by different research laboratories, mainly due to cross-reactivity with other pathogens and standardization of the reagents. The use of recombinant antigens for the serodiagnosis of Chagas' disease is recommended to increase the sensitivity and specificity of serological tests. Expressed in Escherichia call, as fusion products with glutathione S-transferase. sir T. cruzi recombinant antigens (H49, JL7, A13, B13, JL8, and 1F8) were evaluated in an enzyme-linked immunosorbent assay for Chagas' disease, The study was carried out with a panel of 541 serum samples of chagasic and nonchagasic patients from nine countries of Latin America (Argentina, Bolivia, Brazil, Chile, Colombia, El Salvador, Guatemala, I Honduras, and Venezuela). The optimal concentration of each recombinant antigen for coating of plates was determined with the help of 84% labelled recombinant proteins. While the specificity of the epimastigote antigen was 84% because of false positives from leishmaniasis cases, for the recombinant antigens it varied from 96.2 to 99.6%. Recombinant antigens reacted with 79 to 100% of serum samples from chronic chagasic patients. In this way, it is proposed that a mixture of a few T. cruzi recombinant antigens should he employ ed in a diagnostic kit to minimize individual variation and promote high sensitivity in the diagnosis of Chagas' disease."

In this method the perturbation operator -e(-wr2)12/r(12) is introduced, where omega determines the size of the Coulomb hole. The set of parameters for omega has been redetermined to calculate equilibrium bond distances. Calculations have been performed for 41 homo- and heteronuclear singlet diatomic molecules and ions (X (1)Sigma(+)), including atoms of the second and third periods of the periodic table. The soft Coulomb hole correlation energies are compared to the corresponding empirical correlation energies. In general, calculated equilibrium bond distances are in better agreement with the experimental values than Hartree-Fock and Moller-Plesset-2 results. With respect to Moller-Plesset-3, the soft Coulomb hole method gives slightly larger values for the average deviations, except for the homonuclear series. (C) 1999 American Institute of Physics.

In alfalfa, the time course of nodule formation by the AT isolate LPU 83 showed a continued nodulation restricted to the emerging secondary roots, which was probably related to the low rate of nitrogen fixation by the largely ineffective nodules, Results demonstrate the complexity of the rhizobial populations present in the acidic soils represented by a main group of N-2-fixing rhizobia and a second group of ineffective and less-predominant isolates related to the AT strain Or191."

The 1.3 cm continuum emission is detected toward HW2, HW3b, HW3c, HW3d, and HW9. In addition, a new continuum source (Cep A:VLA 1), undetected previously, is observed at this wavelength. We detected three spatial clusters of H2O masers that are associated with the 1.3 cm continuum sources HW2, HW3b, and HW3dii (the brightest component of HW3d), indicating that these objects may harbor an energy source as suggested by Garay and coworkers. The spatial distribution of the H2O masers with respect to the continuum emission is different in each one of these objects. Toward source HW2 the H2O masers are spread over similar to 1 "" and aligned in a direction almost perpendicular to the associated radio jet. In HW3b the H2O masers are spread over a more compact region (-0."" 5) and aligned along the major axis of the elongated radio continuum emission. The masers associated with the compact object HW3dii are distributed over a compact region (similar to 0."" 5) but do not show any clear spatial trend. By comparing the H2O (this paper) and OH maser distributions in the region, we propose that object HW2, with the strongest H2O-OH maser activity, could represent the ""oldest"" young stellar object of the region, while HW3b, with no reported OH maser activity, could be the ""youngest"" source of these three objects."

From Johnson and Stromgren data, we were able to identify three independent frequencies (f(i) = 1.9791 cycle d(-1), f(2) = 1.7268 cycle d(-10) and f(3) = 1.6498 cycle d(-1)) as well as another signal, which we are able to identify as the coupling term between two of the frequencies (f(4) = f(1) - f(2) = 0.2479 cycle d(-1)). These four frequencies are able to account for all of the observed variations down to the la significance level. We discuss another possible interpretation of these frequencies using a model of quasi-stochastic amplitude modulation. In this scenario, we are able to show that HR 8799 might be pulsating with two independent frequencies, one of which undergoes amplitude modulation similar to other gamma Dor objects. In addition, we discuss a preliminary mode identification based on the observed colour curves. Finally, 18 simultaneous, high-resolution echelle spectra were collected on two nights and we qualitatively compare the radial velocities from these data with our photometry."

Partial sequencing of the 16S rDNA indicated that these isolates belong to Sinorhizobium meliloti species. IS-fingerprinting analysis revealed a high diversity among the isolates but some of them appear related to inoculant strains currently used in the region. The S. meliloti isolates showed a decreased growth rate with increasing acidity. They were, however, able to nodulate alfalfa at pH 5.6, but showed a delayed nodulation and decreased nodule number typical of S. meliloti strains. The impaired nodulation of S. meliloti at pH 5.6 did not result in a reduction of alfalfa dry matter production or nitrogen content. However, significant differences were observed for the relative symbiotic effectiveness of the strains analysed. LPU63 (Argentina) was the most effective among the isolates and exhibited a high nodulation competitiveness at both neutral and acidic pH. These results suggest that the isolate LPU63 may be a potential efficient inoculant for alfalfa in acid soils. (C) 1999 Federation of European Microbiological Societies.

Its rapid optical decay can be characterized by a power law with exponent -2.10 +/- 0.13 and a constant underlying source at R-c = 25.5 +/- 0.5. Its optical colors 2.1 days after the burst imply a spectral slope of -0.66 +/- 0.70. The gamma-ray spectrum as observed with BATSE shows that it is among the 4% softest bursts ever recorded. We argue that the rapid optical decay may be a reason for the nondetection of some low-energy afterglows of GRBs.

Two 1.3 cm continuum sources have been detected in the region, coinciding with the infrared sources IRS 1 and IRS 3, respectively. The radio emission in IRS 3 is consistent with an ionized thermal bipolar radio jet. Two clusters of H2O maser spots are detected, one associated with IRS 1 (22 spots) and the other one associated with IRS 3 (13 spots). The H2O maser distribution in IRS I seems to be tracing at scales of 300 AU the larger scale H-2 outflow observed at a few thousands of AU from the exciting source. On the other hand, the H2O masers in IRS 3 are distributed as an apparent disk of similar or equal to 0."" 05 (similar or equal to 20 AU) radius, oriented almost perpendicular to the major axis of the radio jet. There is a clear velocity gradient (similar or equal to 0.35 km s(-1) AU(-1)) along the major axis of the H2O maser distribution, which can be gravitationally bound by a central mass of similar or equal to 1 M-.. These results, together with the low-mass and early evolutionary stage of IRS 3, suggest that masers around this source are tracing a rotating proto-planetary disk within a proto-solar-like system. This represents direct kinematic evidence of the smallest rotating circumstellar disk ever observed around a young stellar object (YSDO). We discuss the dichotomy of H2O masers tracing either outflows or disks around YSOs, based on the evolutionary scheme proposed in our earlier work. We suggested that systems in which H2O masers trace disks are less evolved than those in which masers trace outflows. In this scheme, IRS 3 would then represent a relatively less-evolved object than IRS 1. This prediction is consistent with independent infrared observations showing that IRS 3 is at an earlier phase of evolution."

Radio continuum emission at 3.6 cm had been detected previously toward the center of symmetry of 13 outflows in these regions. With the new 6 cm observations we have been able to estimate the spectral index in the 6 to 3.6 cm wavelength range for 11 of these outflow central (Class 0 and Class I) sources. All the spectral indices obtained for these central sources are positive and consistent with partially thick thermal free-free emission. We discuss this result in relation to the current models for the origin of centimeter radio continuum emission in outflow sources. In particular, we find that the observed flux densities of these sources fit very well in the observational correlation between the radio continuum luminosity and the momentum rate of the outflow, and that the results are consistent with the central sources being thermal radio jets. Our data suggest that the ionized part of the jets begins at a distance less than or similar to 10 AU from the star. In addition, we have derived a positive value for the spectral index of HH 32A, indicative of partially thick thermal emission. For the remaining sources detected in the nine fields observed, our results indicate that the emission is, in general, nonthermal, as expected for background extragalactic sources. However, a few of these sources could be related to the star-forming regions studied."

However, the mechanisms of resistance are unclear. We selected in vitro a Leishmania tropica line resistant to 1.2 mg/mL of Sb(V) of glucantime (GLU-R10). The cell line has a stable phenotype for at least 6 months and a resistance index of 1400-fold. The resistant line has no cross-resistance to pentostam or to SbCl3 and SbCl5. The resistance to glucantime was reverted by buthionine sulfoximine (BSO) and chlorambucil (CLB); however, thiol analyses by HPLC of wild-type and GLU-R10 cell lines, in the presence or absence of the drug, showed no differences between these two cell lines. The resistant line had a DNA amplification shown as a circular extrachromosomal element (G-circle) of approximately 22 kb. However, the specific probes for gamma-glutamyl cysteine synthetase, ornithine decarboxylase and trypanothione reductase did not recognize the G-circle amplified in the GLU-R10. The G-circle did not arise from the H region and was not related with P-glycoprotein Pgp-MDR- or Pgp-MRP-like genes. Northern blot analysis of the G-circle showed that a single transcript of approximately 6 kb was overexpressed. in the resistant line. Molecular characterization of the G-circle would lead to the determination of the gene(s) involved in resistance to glucantime in Leishmania. (C) 1998 Elsevier Science Inc."

We obtain new values for the cluster parameters: E(B-V) = 0.71 +/- 0.08, V-O, - M-V = 11.9 +/- 0.1, and age = (7.5 +/- 3) x 10(6) yr. The combined evidence from the photometric diagrams suggests the presence of a number of pre-main-sequence (PMS) cluster members with spectral types similar to A0 to F5. The interpretation of these objects as PMS candidates is further supported by independent results from CCD uvby H beta observations. If confirmed, these stars would bridge the existing gap in the sample of PMS stars, between the coolest Herbig AeBe stars (HAeBe), and the hottest T Tauri stars. These PMS candidates are located some 0.5 and I mag above the main sequence in the V-(B-V) diagram, around the location of spectral types AF. This feature, together with their locations in the (U-B)-(B-V) diagram and the interpretation that they are PMS members, suggest an additional reddening law with a slope alpha = E(U-B)IE(B-V) similar or equal to 0.55, probably caused by circumstellar material."

It has been difficult to investigate this because of the resolution needed Here we report interferometric observations (at a wavelength of 7 mm) of the core of the star-forming region L1551. We have achieved a linear resolution of seven astronomical units (less than the diameter of Jupiter's orbit). The core of L1551 contains two distinct disks, with a separation of 45 AU; these appear to be associated with a binary system. Both disks are spatially resolved, with semi-major axes of about 10 AU, which is about a factor of ten smaller than disks around isolated stars(9-12).

The spectrum from the core is of low excitation with T-e(N II)= 8000 K and n(e)(S II)= 550 cm(-3). KjPn 8 is found to be a Type IPN according to the original classification scheme of Peimbert & Torres-Peimbert, with enriched He/H and N/O ratios with respect to mean values for PN. Increased O/H, Ne/H and Ar/H ratios over those of average PN reflect the possible metal-rich environment from which the progenitor star formed, and also are similar to those found in the extreme Type I PN He 2-111. The N/H ratio is found to be only moderately high compared to the average PN and consequently, the large O abundance pulls the N/O ratio towards the lower limit of the criterion for Type I planetary nebulae (PNe) in this case. In addition, the spectra of some knots and faint regions ia the KjPn 8 surroundings are presented, which show only a few spectral lines. Low electron densities ranging from 100 to 300 cm(-3) have been derived in these outer regions."

The glycosome-associated enzyme is not membrane-bound as it was recovered quantitatively in the aqueous phase of the biphasic system formed by Triton X-114 at 30 degrees C, Studies with digitonin-permeabilized intact epimastigotes demonstrated the presence of two pools of soluble HMG-CoA reductase in these cells, associated to the cytoplasmic and glycosomal compartments. Steady-state kinetic studies of the glycosome-associated enzyme indicated classical Michaelis-Menten behavior with K-m,K-app (HMG-CoA) 28 +/- 3 mu M, K-m,K-app (NADPH) 37 +/- 4 mu M, and V-m,V-app 3.9 +/- 0.2 nmol/min mg protein; the transition-state analog lovastatin behaved as a competitive inhibitor with respect to HMG-CoA with K-is 23 nM and a noncompetitive inhibitor toward NADPH with K-ii 29 nM. The results are in complete agreement with recent gene cloning and expression studies which showed that T. cruzi HMG-CoA reductase lacks the NH2-terminal membrane-spanning sequence, This is the first demonstration of a soluble eukaryotic HMG-CoA reductase and also the first report on the presence of an enzyme of the isoprenoid biosynthesis pathway in glycosomes.

We derive a critical density above which a cloud remains radiative after compression by the jet cocoon. The critical density depends mainly on the cocoon pressure. Supercritical clouds increase in emission-line brightness, while subcritical clouds generally are highly overheated, reducing their luminosity below that of the intercloud medium. As a result of the pressure stratification in the bow shock of the jet, a cylindrical structure of nested shells develops around the jet. The most compact and brightest compressed clouds surround the cloud-free channel of the radio jet. To support our analytical model, we present a numerical simulation of a supersonic jet propagating into a clumpy NLR. The position-velocity diagram of the simulated H alpha emission shows total line widths of the order of 500 km s(-1) with large-scale variations in the radial velocities of the clouds due to the stratified pressure in the bow shock region of the jet. Most of the luminosity is concentrated in a few dense clouds surrounding the jet. These morphological and kinematic signatures are all found in the well-observed NLR of NGC 1068 and other Seyfert galaxies."

These igneous (partially metamorphosed) rocks, and their host granulites, gneisses and migmatites of probable Precambrian age, are highly folded. The sulphide ore, consisting of pyrrhotite, pentlandite and chalcopyrite, occurs in the cores of both antiform and synform structures, within dunite, harzburgite and mainly along shear zones in bronzitite, replacing small mylonitic subgrains. The platinum-group mineral assemblage is dominated by Pd bismuthotellurides (Pt-free merenskyite, palladian bismuthian melonite and michenerite), with minor sperrylite, and PGE-sulpharsenides. The latter often occur as single, zoned crystals frequently showing cores of irarsite; outside these are concentric zones of cobaltian hollingworthite, rhodian nickelian cobaltite and Fe-rich nickelian cobaltite. Mineralogical, textural and chemical evidence indicate that the sperrylite and platinum-group element sulpharsenides were formed during a primary magmatic event associated with the fractionation of a basaltic melt, which was contaminated by the assimilation of metamorphic crustal rocks. PGE sulpharsenides crystallized from As-bearing, residual magmatic liquids that collected PGE and segregated after the crystallization of the monosulfide solid solution. During high-grade metamorphism, sulpharsenides were remobilized as solid crystals in the liquated sulfides suffering partial dissolution and fracturing. On the other hand, there is no evidence of a primary concentration of Pd-bismuthotelluride minerals, and their present spatial distribution is only the consequence of their formation under high-to medium-grade metamorphism, down to temperatures of below 500 degrees C. Pd bismuthotellurides crystallize even in fractures of sulpharsenides, attached to the boundaries of highly dissolved sulpharsenide crystals, and intergrown with molybdenite."

Two-dimensional calculations of remnants caused by a strong energy deposit in a low metal abundance ISM are here shown to undergo breakout once encountering a steep density gradient, leading to a fast-moving shell capable of producing the broad and faint emission lines. Energetic sources lead to fast, thick, and hot shells, and when evolving in a low-metallicity ISM, to quasi-adiabatic shells that strongly delay their fragmentation owing to Rayleigh-Taylor instabilities. At the same time, these are smoothly accelerated to reach large distances from the breakout point. The shell acceleration is promoted by the passage of several shocks with small relative speeds, caused by the continuous push exerted by the hot gas that steadily increases its speed to fill the deformed superbubble volume."

A major drawback to cope with is the complexity of T. cruzi genetics, that hinders the construction of a comprehensive genetic map. As a first step towards physical mapping, we report the construction and partial characterization of a T. cruzi CL-Brener genomic library in yeast artificial chromosomes (YACs) that consists of 2,770 individual YACs with a mean insert size of 365 kb encompassing around 10 genomic equivalents.

We find evidence in the ammonia maps for heating and line broadening toward VLA 2, confirming that this source is driving the large lobe pair of the quadrupolar molecular outflow. Additionally, H2O maser emission is detected toward this radio continuum source. A second, very compact ammonia ''hot spot'' is observed 10'' west of VLA 2. This ''hot spot'' may be heated by a deeply embedded (still undetected) young stellar object that could be the driving source of the more compact pair of molecular outflow lobes.

Two arbuscular mycorrhizal (AM) fungi belonging to different Glomus species were assayed. Populations of S-cycling microorganisms varied along the growth period for both AM fungi colonized and uncolonized plants, with significant quantitative and qualitative changes in the mycorrhizal compared with the non-mycorrhizal root zone, The occurrence of autotrophic sulphur oxidizers in pot cultures colonized with G. fasciculatum was significantly higher than in non-mycorrhizal ones throughout the plant growth period. The population size of this group was similar in non-mycorrhizal and G. mosseae colonized soil, The population of anaerobic sulphur mineralizing microorganisms was significantly decreased by mycorrhizal colonization. In contrast, pot cultures colonized by G. mosseae or G. fasciculatum had a higher quantity of sulphate-reducing bacteria than the control. The fact that the autotrophic S oxidizers and sulphate-reducing root-associated microorganisms were selectively stimulated by each one of the AM fungi assayed is a noticeable aspect. The maximum activity of the microbial processes regarding specific groups was at 15 days for the mineralizing, 45 days for the oxidizing and 0 days for the reducing microorganisms. In the case of autotrophic S oxidizers, the maximum population was achieved by 30 days in G. fasciculatum colonized treatment. From the data on occurrence of physiological grouping of sulphur-cycling microorganisms, we can deduce that a different ecological situation existed in the rhizosphere developed by non-mycorrhizal plants compared with those colonized by each one of the mycorrhizal endophytes.

The relative contribution of the compact component to the total emission varies from 15 to 100%. About half of the compact components appear spherically symmetric while the other half displays an elongated structure. There is, however, no correlation between the optical jet axis and the flattened dust structures, indicating that collimation occurs on smaller scales. Close to the energy source of HH 114 we discovered a so far unknown mm-source with L-bol/L-smm < 100 suggesting that it is still in its early protostellar evolutionary stage.

The number of participating laboratories increased from 10 in the first exercise (GEP-92) to 19 in the last exercise (GEP-95). Despite this increasing number of participating laboratories, results remained satisfactory. In the last exercises, all the laboratories used PCR-based DNA polymorphisms with an increasing number of markers obtaining good results. SLPs were used by only 30% of laboratories in the last two exercises but the results indicated a good level of expertise in most of these laboratories.

Two bright, point-symmetric arcs have been detected in the core of Cn 3-1, extending from the equator towards the polar regions of the ellipsoid. The arcs seem to be filamentary structures located on the ellipsoid, The origin of the arcs could be related to some sort of collimated bipolar ejections along a rotating axis, Relatively high mean [N II]/H alpha similar or equal to 0.83 and [S II]/H alpha similar or equal to 0.056 line intensity ratios are found in Cn 3-1, Maximum values of [S II]/H alpha of similar or equal to 0.083 are found in the arcs. The estimated kinematical age and ionized mass of Cn 3-1 are similar or equal to 1300 yr and similar or equal to 4 x 10(-2) M., respectively. M 3-27 is unresolved at 3.6 cm (size less than or equal to 0.6 arcsec), The detected [N II] and [S II] emission lines arise in a compact (size less than or equal to 1.4 arcsec), probably non-spherical region, which is identified with the ionized shell of M 3-27, The Ha emission from M 3-27 is dominated by strong stellar emission and exhibits a type III P Cygni profile with very extended wings (similar or equal to 3000 km s(-1)). A kinematical age of less than or equal to 530 yr and an ionized mass of similar or equal to 3 x 10(-4) M. are estimated for M 3-27, Extended haloes (size similar or equal to 36 arcsec in Cn 3-1, similar or equal to 24 arcsec in M 3-27) have been spectroscopically detected in both objects through their [N II] and/or H alpha emissions, An analysis of the kinematical and emission properties of the haloes strongly suggests that they are reflection nebulosities and contain large amounts of neutral material, and that the distribution of neutral material in them is largely isotropic."

The morphology of the (CO)-C-13 map is similar to the (CO)-C-12 1-0 and 2-1 maps. Maps of the (CO)-C-12 2-1/1-0 and (CO)-C-12/(CO)-C-13 1-0 ratios show small variations of the ratios throughout the disk with a rise of the (CO)-C-12 2-1/1-0 ratio towards the southeast. The values found are within the range as found in other galaxies. Radiative transfer calculations indicate a kinetic temperature of 10-15 K and H-2 densities on the order of 3 x 10(4) cm(-3). In the southeastern part of the dust lane, the gas appears to be warmer (20-30 K) which may be due to a greater star formation activity. The total molecular mass is about 1.2 x 10(8) M.. The observed (CO)-C-12 2-1 intensity is consistent with the molecular gas being distributed in a thin, warped disk as modelled by Quillen et al. (1992).

In this regime the cooling distance of the swept-up gas in the bowshock of the jet is of the same order as the transverse extent of the jet bowshock, as opposed to the more extreme regimes found for more powerful adiabatic large-scale jets or the slow galactic jets which have previously been simulated. We calculate the emissivity for the Ha line and for radio synchrotron emission. We find that the structure of the line-emitting cold envelope of the jet cocoon is strongly dependent on the nonstationary dynamics of the jet head as it propagates through the ambient medium. We observe the formation of cloud-like high density regions which we associate with NLR clouds and filaments. We find that some of these clouds might be partially neutral and represent sites of jet-induced star formation. The calculated Ha flux and the spectral line width are consistent with NLR observations. The simulation of the radio-optical emission with radiative cooling confirms the basic result of the geometric bowshock model developed by Taylor et al., i.e. that the start of noticeable optical line emission can be significantly offset from the hotspot of the radio emission. However, the time-dependent nature of the jet dynamics implies significant differences from Taylor et al.'s geometric bowshock model."

Plant dry weights of non-AM-inoculated maize and lettuce were unaffected by the presence of A. alternata and F. equiseti. In contrast, A. alternata and E. equiseti decreased plant dry weights and mycorrhization when inoculated to the rhizosphere before C. mosseae. The saprophytic fungi inoculated 2 weeks after G. mosseae did not affect the percentage of root length colonized by the AM endophyte, but did affect its metabolic activity assessed as succinate dehydrogenase activity. Although F. equiseti inoculated at the same time as G. mosseae did not affect mycorrhization of maize roots, its effect on AM colonization of lettuce roots was similar to that with A. alternata. In the rhizosphere of both plants, the population of saprophytic fungi decreased significantly, but was not affected by the presence of G. mosseae. Our results suggest that there may have been a direct effect of the saprophytic fungi on the mycorrhizal fungi in the extramatrical phase of the latter, and when the AM fungus was established in the root the AM fungus was less affected by the saprophytic fungi."

The isotherms of MBT adsorption followed the Freundlich model. Due to the similar physico-chemical and mineralogical properties of the soils from this area, the K-f values were only correlated with soil clay content, smectite content, and soil surface area. Methabenzthiazuron degradation did not occur in the soils, under our experimental conditions, for incubation periods of up to 42 d. Methabenzthiazuron was not detected in the eluates from the clay and silt loam soil columns; it was retained in the first 3-cm layer and the retardation factor values, R, were 24 and 14, respectively. A computation model simulating a uniform flow of water and instantaneous adsorption-desorption equilibrium is suitable for the description of MBT in the G-8 soil but showed an overestimation in the G-11 soil column."

Anti-TcMe antibodies inhibited the infectivity of fibroblast LLC-MK2 cells by 34% relative to a preimmune serum. The epitope was specifically recognized by 55% of the sera from 80 chagasic patients. The anti-TcMe antibody immunoprecipitated proteins of about 60 and 40 kDa from epimastigote and cell-culture trypomastigote forms, respectively. It is likely that the 60- and 40-kDa proteins are processed from higher-molecular-weight precursors, since the antibody immunoprecipitated protein fractions in the range of 115-150 kDa from in vitro translation products of poly A(+) RNA."

Additionally, we searched for the 6(16) - 5(23) H2O maser line towards nine regions, detecting a weak H2O maser near IRAS 20188+3928. We detected and mapped NH3 emission in 14 of the 15 regions observed, and we estimated physical parameters for the high density gas. We systematically found that the position of the best candidate for the outflow excitation in each region is very close to an NH3 emission peak. From a statistical study of the data presented in this paper, together with previously published data, we conclude that the NH3 line emission is more intense towards molecular outflow sources than towards sources with only optical outflows. Therefore, molecular outflows appear to be associated with larger amounts of high density gas. This result suggests a possible evolutive scheme in which young objects associated with molecular outflows lose progressively their neighboring high-density gas, weakening both the NH3 emission and the molecular outflow in the process, and making optical jets more easily detectable as the total amount of gas decreases."

Five networks were established through wide publicity, holding meetings of key laboratories and developing proposals which were then reviewed by the Steering Committee of Strategic Research for financial support. The aim of the Programme was to use the platform of these networks to: (1) train scientists From tropical disease-endemic countries; (2) transfer technology and share material and expertise, thereby reducing costs anti increasing efficiency; and (3) provide an information system that is accessible globally as soon as the results become available. The initial target suits to produce a low-resolution genome map for each of the parasites, but it soon became evident that by using rapidly developing technologies, it might be feasible to complete DNA-sequence analysis for some of the parasites in the next decade, as discussed here by Alberto Carlos Frasch and colleagues, with particular focus on the T, cruzi genome initiative."

Six have been observed previously at 1300 mu m, and two were also detected by IRAS. We observed eight of the new sources at six wave bands from 350 to 2000 mu m and derived upper limits for their far-infrared (FIR) emission from the IRAS raw data. The millimeter/submillimeter emission originates from cold dust (T-d similar to 20 K), and the individual components have gas masses of 5 M. < M(gas) < 36 M.. The ratio L(bol)/L(smm) is below 70 for six sources associated with OMC-3, indicating that they are class 0-type objects. Condensations in the OMC-2 region have L(bol)/L(smm) less than or equal to 360, suggesting an evolutionary effect from north to south. We report the discovery of a highly collimated bipolar CO outflow, most likely driven by the source OMC-3 MMS 8. The flow is over 5' (0.7 pc) long and less than 1' (0.15 pc) wide and is oriented nearly east-west. Less prominent outflows are associated with OMC-2 FIR 2/3 and OMC-3 MMS 6. The 1300 mu m continuum emission is confined to a ridge less than 1' wide while the emission in J = 2-1 (CO)-C-13, (CO)-O-18, and CS is between 5' and 10' wide. The continuum emission is displaced toward the eastern side of the molecular ridge that contains it. Most 1300 mu m sources lie in or close to line emission peaks. However, not all line emission peaks contain prominent 1300 mu m continuum sources. The curved filamentary structure of the large-scale dust and molecular emission is likely the result of compression by the superbubble centered similar to 25-70 pc further north, plus the impact of energy from the younger Ic subgroup of the Orion OB association, which lies 10-50 pc in front of our mapped region, and by the very recent expansion of the NGC 1977 and M42H II regions."

This alignment, and the flux density and deconvolved angular size dependences with frequency observed between 3.6 and 6 cm, are consistent with VLA 2 being a thermal radio jet and suggest that this source is related to the excitation of the larger pair of outflow lobes. Under this interpretation, the second, more compact lobe pair most probably constitutes an independent bipolar outflow, whose exciting source is still to be determined."

Results showed a high functional compatibility between Medicago species and autoctone endophytes, and a specific plant response to individual Glomus species. Differences among the Medicago species in their reaction to Glomus species ranged from negative to highly positive. A combination of host and AM fungal species indicates that a specific compatibility exists among symbionts. Nutrient uptake as a result of AM colonization also indicated a wide degree of responsiveness in each species according to the associated fungal symbiont to the plant, A positive effect on N, P and K, and negative on Ca and Mg nutrition was found in all mycorrhizal treatments, especially with the autoctone endophytes. Mycorrhizal infectivity could not be related to endophyte effectiveness, with generally fewer and larger Rhizobium nodules found on the most effective mycorrhizal treatments. Results support the role of indigenous AM endophytes in the efficacy of mycorrhizal symbiosis and the importance of host-endophyte selection to maximize growth and nutrition of Medicago. This study shows that AM symbiotic efficiency attributed to Medicago is dependent on endophyte association and plant species. The importance of selecting suitable AM fungi is of practical interest for improving the effectiveness of the tripartite symbiosis."

In this report, the Early Breast Cancer Trialists' Collaborative Group present their third 5-yearly systematic overview (meta-analysis), now with 15 years' follow-up. Methods in 1995, information was sought on each patient in any randomised trial of ovarian ablation or suppression versus control that began before 1990. Data were obtained for 12 of the 13 studies that assessed ovarian ablation by irradiation or surgery, all of which began before 1980, but not for the four studies that assessed ovarian suppression by drugs, all of which began after 1985. Menopausal status was not consistently defined across trials; therefore, the main analyses are limited to women aged under 50 (rather than ''premenopausal'') when randomised. Oestrogen receptors were measured only in the trials of ablation plus cytotoxic chemotherapy versus the same chemotherapy alone. Findings Among 2102 women aged under 50 when randomised, most of whom would have been premenopausal at diagnosis, 1130 deaths and an additional 153 recurrences were reported. 15-year survival was highly significantly improved among those allocated ovarian ablation (52 . 4 vs 46 . 1%, 6 . 3 [SD 2 . 3] fewer deaths per 100 women, logrank 2p=0 . 001), as was recurrence-free survival (45 . 0 vs 39 . 0%, 2p=0 . 0007). The numbers of events were too small for any subgroup analyses to be reliable. The benefit was, however, significant both for those with (''node positive'') and for those without (''node negative'') axillary spread when diagnosed. In the trials of ablation plus cytotoxic chemotherapy versus the same chemotherapy alone, the benefit appeared smaller (even for women with oestrogen receptors detected on the primary tumour) than in the trials of ablation in the absence of chemotherapy (where the observed survival improvements were about six per 100 node-negative women and 12 per 100 node-positive women). Among 1354 women aged 50 or over when randomised, most of whom would have been perimenopausal or postmenopausal, there was only a non-significant improvement in survival and recurrence-free survival. Interpretation In women aged under 50 with early breast cancer, ablation of functioning ovaries significantly improves long-term survival, at least in the absence of chemotherapy. Further randomised evidence is needed on the additional effects of ovarian ablation in the presence of other adjuvant treatments, and to assess the relevance of hormone-receptor measurements."

Based on specific growth rates, carbon source utilization and acid production, 13 out of the 15 isolates could be assigned to the slow-growing group of rhizobia (bradyrhizobia). Using antisera against whole cells of three isolates, we separated the 15 isolates into three serogroups. Only the slow-growing isolate Ls4 and the fast-growers Ls5 and Ls552 lacked cross-reactivity with any of the sera tested. Electrophoretic mobilities of whole cell protein from seven out of the eight isolates included in the serogroup represented by strain Ls31 were identical. Similarly, isolates Ls1B3 and Ls 1B4, both in serogroup Ls 1B3, had the same pattern of cell proteins. In contrast, isolates Ls3 and Ls7, belonging to serogroup Ls7, differed in protein profile. Plant growth experiments carried out under bacteriologically controlled conditions revealed that all of the isolates effectively nodulated L. subbiflorus and L. pedunculatus, but were unable to form effective nodules on L. tenuis and L. corniculatus. All isolates showed similar effectiveness in symbiosis with L. subbiflorus, except isolate Ls7, which gave significantly higher plant dry weight."

About one half of these cores have a compact core surrounded by an extended envelope. The lambda 1.3 mm dust emission maps were compared with NIR (2.13 mu m) and FIR (IRAS) maps to discriminate between isothermal and self-luminous cores. About one half of the cores were classified as isothermal. A comparison of virial masses derived from CS line widths with gas masses derived from lambda 1.3 mm dust emission shows that virial masses are on average by a factor of 20 ... 30 larger.

It was recorded at three sites, Beznar, Alhama, and Santa Fe, within about 40 km of the epicenter. It was also recorded by three NARS network stations (NE11, NE13 and NE14), which were in operation in Spain at the time. The data from Alhama and NE14, however, are not usable because of instrumental problems, The fact that the epicenter of the 1984 event was relatively close to the highly destructive earthquake of 25 December 1884 (M = 6.7-7.1) makes the source study of the 1984 event very interesting and useful. By synthetic modelling of the regional seismograms at NE11, NE13 and Toledo, the seismic moment is estimated as 3.0 x 10(23) dyne-cm (M(w) = 5.0). Source spectra estimated from accelerograms at Beznar and Santa Fe suggest that Holocene sediments (200 m in thickness) at Santa Fe may cause broadband amplification of about 10. From the spectra obtained from the Beznar accelerogram, the corner frequency is estimated as 1 Hz, which gives a stress drop of about 100 bar. We have synthesized expected ground motions at Santa Fe and Beznar from a postulated M(w) = 7.0 earthquake (similar to the 1884 event) using recordings of the 1984 event as empirical Green's functions. The simulations suggest that the horizontal accelerations during the postulated event may be 8-10 times greater than those observed during the 1984 event, exceeding 1/4 g at Santa Fe. Because of their close proximity and similar subsoil conditions, estimations at Santa Fe may also be valid for the lower part of the city of Granada. We finally compare the expected response spectra for the postulated event with the proposed design spectra."

We report measurements of C IV lambda 1549, He II lambda 1640, and O III] lambda 1663 paired to measurements of H beta, He II lambda 4686, and Fe IIopt in 52 low-redshift AGNs (z less than or similar to 0.8). Ultraviolet archival spectra covering the region of C IV lambda 1549 were obtained with the Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST). Moderate-resolution optical spectra (approximate to 4-7 Angstrom) were obtained in most cases within two years of the HST observations. We present an atlas of matching C IV lambda 1549 and H beta broad-line profiles. Velocity centroids at different profile heights and other profile properties were measured after removal of narrow-line components and contaminating satellite lines of other elements. Our results add refinements to the ''standard view'' of nebular conditions in the broad-line region (BLR). (1) The average electron density is most probably weighted toward values higher than expected in standard BLR models. The weakness of O III] lambda 1663 and N IV] lambda 1486 relative to He II lambda 1640 suggest that the semiforbidden lines are collisionally de-excited at n(e) greater than or similar to 10(10.5) cm(-3). (2) There is evidence, supporting earlier work, that photoionization via Ly alpha fluorescence plays a major role in the production of Fe IIUV. We identify and discuss briefly the Fe IIUV multiplets in the range 1550-1750 Angstrom. (3) The observational distinction between the narrow- and broad-line regions is blurred by the contribution of a region of intermediate density (10(6) cm(-3) less than or similar to n(e) less than or similar to 10(7) cm(-3)). Best evidence for this emission comes from the [O III] lambda 4363 and C IV lambda 1549 profiles. It is most likely associated with the innermost part of the narrow-line region. Comparisons between the broad-line profile of C IV lambda 1549, H beta and, whenever possible, He II lambda 1640 suggest (1) that radio-loud and radio-quiet AGNs are very different classes of objects that should be treated separately, and (2) that ionization structure varies within the velocity field. The extreme radial velocity emission is characterized by a high-ionization spectrum dominated by C IV lambda 1549 and He II. Several basic results are: (i) C IV lambda 1549 is almost always blueshifted with respect to H beta. (ii) There is a fundamental kinematic difference between radio-loud and radio-quiet objects relative to the rest frame of the AGN. (iii) Radio-loud objects show predominantly redshifted and asymmetric H beta and unshifted symmetric C IV lambda 1549. (iv) Radio-quiet objects show predominantly blueshifted and asymmetric C IV profiles with H beta usually symmetric and unshifted. Correlation analysis of the radio-quiet sample suggests that C IV lambda 1549 EW, C IV lambda 1549 shift/asymmetry, and the strength of Fe IIopt are related. C IV lambda 1549 profiles with large blueshift/asymmetry show lower EW and stronger Fe IIopt emission. The results suggest that C IV lambda 1549 and H beta arise in different velocity/geometry regimes. C IV lambda 1549 may be predominantly emitted in an outflowing bicone of large aperture (similar to 45 degrees), while Fe IIopt is most probably emitted in a strongly flattened geometry (possibly an accretion disk). Bulk H beta emission may come from a less flattened configuration of clouds. In this interpretation, the flux ratio Fe IIopt/H beta(BC) is an aspect indicator for radio-quiet objects. Radio-loud objects are more enigmatic, and the existence of a reliable optical aspect indicator remains uncertain. There is evidence that line profile properties of C IV lambda 1549 and HP are ''coupled'' in the radio-loud sample, suggesting that a common origin for the high- and low-ionization line emission is a possibility. If this is true, however, we do not have a reasonable explanation for the predominance of H beta redshifts and red asymmetries in that population."

The inoculation of maize plants with A, alternata and F. equiseti simultaneously with spores of G, mosseae significantly decreased the percentage of root length colonized by AM fungi, but there was no effect on AM colonization when G. mosseae was introduced before A. alternata and F. equiseti.

Determinations of dry matter production and concentrations of N, P, K, Ca and Mg in plant tissues showed that mycorrhizal colonization increased content of N, P and K and overall yield, but decreased the concentration of Ca and Mg in plant shoots. The response of mycorrhizal colonization to different amounts of extractable soil Ca indicated that, while mycorrhiza formation was not sensitive to soil Ca it induced a reduction of Ca in the plant. This study demonstrated that AM fungi modulate the ion ratios and ion balance in the plant. In general, the nutrient/Ca ratios were higher in AM than in non-AM plants. These results show that AM formation enhanced N, P and K and decreased Ca uptake. The mycorrhizal condition affected plant tolerance to nutrient deficiency or excess by modifying uptake. Only in AM plants were differences observed between the effects of varying Ca availability. There was a positive correlation between plant Ca content and nodulation in the mycorrhizal treatments. On the other hand, nodulation was not correlated with N, P and K contents. Calcium amendments had no effect on nodule formation in nonmycorrhizal plants, but nodule production was highly increased in AM plants, particularly at the highest Ca level. The correlation coefficients for parameters related to absorption of nutrients in mycorrhizal plants were highly significant for N and P, as well as for Ca and nodulation. According to our results, the mycorrhizal effect on Ca assimilation was not a simple buffering effect associated with Ca excess. The impact of AM function is dependent on various soil and environmental factors. The mechanisms by which AM fungi are able to alleviate nutrient excess has yet to be understood. Further research will be necessary to elucidate this effect."

We find that the spectral indices of the emission from these compact objects, in the frequency interval from 1.5 to 15 GHz, cover a wide range, from -0.6 to 0.7. Positive spectral indices are exhibited by sources 2, 3b, 3c, and 3d. The first and last of these objects, the brightest sources within Cep A East, exhibit in addition elongated morphologies and angular-size and flux-density dependences with frequency that suggest they correspond to confined jets of ionized gas. Most of the objects that appear in string structures exhibit a mixture of flat and negative spectral indices across their faces, which indicates the presence of both thermal and nonthermal emission. The spectral indices of the integrated emission from sources 1b, 4, 6, and 7a are in the range between -0.3 and -0.1 while those of sources 1a, 5, 7b, and 7c are even more negative (-0.6 less than or equal to alpha less than or equal to -0.4). We suggest that the radio emission from the string sources arises in shocks resulting from the interaction of confined stellar winds with the surrounding medium. The duality in emission mechanisms is expected in shock waves where a small fraction of the electrons are accelerated to relativistic velocities, giving rise to nonthermal emission, while most of the electrons produce thermal free-free emission. We find that the nonthermal emission dominates the thermal emission when the density of the thermal electrons is below a critical density of similar to 5 x 10(3) cm(-3). We also observed the Cep A West radio source, which consists of two compact components and an elongated, diffuse, champagne-like structure. We find that the spectral index between 1.5 and 5 GHz of the peak and of the integrated emission from the latter component are -0.1 and -0.4, respectively. We suggest that the radio emission from the diffuse source arises from shocked gas at the edge of a cavity driven by a wind that originates from the brightest compact radio object within this region, which shows a spectral index at the peak of the emission of 0.6."

To calibrate the 1.3 cm continuum emission, we used the strong (similar to 1000 Jy) H2O maser source as the reference, thus correcting the amplitude and phase instabilities introduced by the atmosphere. This powerful technique, first applied here to a star-forming region, allowed us to achieve a dynamic range of 15,000 : 1 for the strongest maser feature, a signal-to-noise ratio (S/N) of 70 : 1 for the radio jet and an accuracy of the order of 1 mas in the relative positions between the radio-continuum jet and the H2O masers in the region. We resolved the 1.3 cm jet into two maxima plus a fainter tail to the southwest. The separation between these two maxima (0 ''.14) and the total size of the jet (0 ''.39) are both consistent with models for a biconical ionized jet. The observed flux density (39 mJy) is, however, higher than expected. We detected 39 H2O maser spots toward the Cepheus A region, 28 of which are associated with the HW2 object, most of them distributed on either sides of the radio jet. We suggest that these latter maser features might be tracing a circumstellar molecular disk of radius similar to 300 AU, nearly perpendicular to the radio jet. The velocity gradient of 30 +/- 10 km s(-1) observed in the H2O spots over 600 AU along the axis perpendicular to the radio jet could be gravitationally bound by a central mass of 70 +/- 40 M.."

An analysis of the overall morphology, kinematics, and excitation of the ambient cloud core is presented. In particular, the mean rotational temperature derived over a region of 2' x 2' around FIRS 1 is found to be 12 K, whereas it increases to 30 K at distances within 6 '' from FIRS 1, indicating that FIRS 1 is the dominant energy source in the cloud core. By averaging the blueshifted (V-LSR = -6.1 --> +5.7 km s(-1)) and redshifted (V-LSR = +10.7 --> +22.5 km s(-1)) spectral channels of the VLA data with respect to the ambient cloud velocity (V-LSR = 7.0-9.4 km s(-1)), we have detected an excess of emission (above the expected continuum) that we identify as high-velocity ammonia emission associated with the YSO FIRS 1. The blue- and redshifted emissions seem to have a bipolar morphology, suggesting that they trace a bipolar ammonia outflow of similar to 20 '' in size and aligned with the radio continuum jet. We identify this high-velocity ammonia emission, with an estimated mass M(H-2) similar or equal to 0.2 [XNH(3)/10(-8))](-1) M., as associated with the molecular gas entrained by the radio jet. In addition, NH3 (1,1), (2,2), and (3,3) spectra of this region taken with the Haystack and the Effelsberg 100 m telescopes show ammonia emission at even higher velocities (up to similar to 30-40 km s(-1) from the line center) than those observed with the VLA (less than or similar to 20 km s(-1)), suggesting that the VLA observations cover only a fraction of the velocity range of the ammonia outflow. New VLA ammonia observations covering a higher velocity range are needed to fully map this high-velocity molecular emission and to confirm its bipolar distribution."

The plant Rhizobium sp. - mycorrhiza symbiosis system may increase in yield and nutrition in association with specific rhizosphere bacteria that solubilize calcium, iron, and aluminium phosphates. No benefit from phytate-mineralizing bacteria was found under these experimental conditions. P. phaseloides growth responses were influenced in different ways by specific combinations of the selected bacteria and arbuscular mycorrhizal fungi. Considerable stimulation of nutrient uptake was observed with fungus-bacteria combinations of Azospirillum sp. 1, Bacillus sp. 1 or Enterobacter (spp. 1 or 2) associated with G. mosseae. The fact that Bacillus sp. 1, a calcium-phosphate solubilizing isolate, positively interacted with G. mosseae and negatively with G. fasciculatum is an indication of specific functional compatibility between the biotic components integrated in the system. From our results, the interactions between bacterial groups able to solubilize specific phosphate and mycorrhizal fungi cannot be interpreted as occurring only via P solubilization mechanisms since no generalized effect was obtained. Iron-phosphate solubilizing microorganisms were more active alone than in dual associations with Glomus sp., but the aluminium-phosphate dissolving isolates positively interacted in mycorrhizal plants. Further work is needed in this area in order to elucidate the mechanisms that affect rhizosphere microorganism interactions. G. mosseae was more effective but less infective than G. fasciculatum in most of the combined treatments."

Randomized trials of radiotherapy and surgery for early breast cancer may have been too small to detect differences in long-term survival and recurrence reliably. We therefore performed a systematic overview (meta-analysis) of the results of such trials. Methods. Information was sought on each subject from investigators who conducted trials that began before 1985 and that compared local therapies for early breast cancer. Data on mortality were available from 36 trials comparing radiotherapy plus surgery with the same type of surgery alone, 10 comparing more-extensive surgery with less-extensive surgery, and 18 comparing more-extensive surgery with less-extensive surgery plus radiotherapy. Information on mortality was available for 28,405 women (97.4 percent of the 29,175 women in the trials). Results. The addition of radiotherapy to surgery resulted in a rate of local recurrence that was three times lower than the rate with surgery alone, but there was no significant difference in 10-year survival; among a total of 17,273 women enrolled in such trials, mortality was 40.3 percent with radiotherapy and 41.4 percent without radiotherapy (P=0.3). Radiotherapy was associated with a reduced risk of death due to breast cancer (odds ratio, 0.94; 95 percent confidence interval, 0.88 to 1.00; P=0.03), which indicates that, after 10 years, there would be about 0 to 5 fewer deaths due to breast cancer per 100 women. However, there was an increased risk of death from other causes (odds ratio, 1.24; 95 percent confidence interval, 1.09 to 1.42; P=0.002). This, together with the age-specific death rates, implies, after 10 years, a few extra deaths not due to breast cancer per 100 older women or per 1000 younger women, During the first decade or two after diagnosis, the excess in the rate of such deaths that was associated with radiotherapy was much greater among women who were over 60 years of age at randomization (15.3 percent vs. 11.1 percent [339 vs. 249 deaths]) than among those under 50 (2.5 percent vs. 2.0 percent [62 vs. 49 deaths]). Breast-conserving surgery involved some risk of recurrence in the remaining tissue, but no significant differences in overall survival at 10 years were found in the studies of mastectomy versus breast-conserving surgery plus radiotherapy (4891 women), more-extensive surgery versus less-extensive surgery (4818 women), or axillary clearance versus radiotherapy as adjuncts to mastectomy (4370 women). Conclusions. Some of the local therapies for breast cancer had substantially different effects on the rates of local recurrence - such as the reduced recurrence with the addition of radiotherapy to surgery - but there were no definite differences in overall survival at 10 years."

CO emission was detected in five of the galaxies. The 43'' beam of the SEST, at 115 GHz, was small enough for determining the general distribution of the gas, which is centrally peaked in all the cases, and the velocity field from which we could derive the major axis position angle and the rotation curve. The latter is, in general, very steep at the centre and quite flat after the turn-over point. It was used to estimate the total mass of the galaxy up to the farthest measured point. The gas mass was estimated from the CO and H I global velocity profiles. On three of the galaxies the (CO)-C-12(2-1) and (CO)-C-13(1-0) lines were also observed on their centres, the first one on a 10'' grid, covering a region of 20'' x 20'', and the second on one point towards the centre. The average ratio between the intensities of the (CO)-C-12(2-1) and (CO)-C-12(1-0) spectra is 1.3 in the three cases. The detections of the (CO)-C-13(1-0) were only marginal.

The Z-locations of the cluster sample display a well-defined Z-age stratification. The Cepheid sample has ages between 3 and 8 x 10(7) yr and shows a departure from the midplane similar to the one observed for clusters of the same age range. The existence of such an age gradient seems to corroborate previous hypotheses suggesting that the star formation activity was probably triggered by the same strong perturbation which originated the depression. A model in which the Big Dent was created by a collision of a high-velocity cloud with the Galactic disk is able to reproduce the observed gradient.

We identify a core sample of C IV lambda 1549 and H beta profiles with a wide distribution of red- and blueshifts (less than or equal to+/-1000 km s(-1)). We also identify two tails in this distribution: one with large HE redshifts (greater than or equal to 2000 km s(-1)) and another with large C IV blueshifts (greater than or equal to 1500 km s(-1)). The tails are mutually exclusive. All objects with extreme H beta redshift are radio loud, and all objects with extreme C IV blueshift are radio quiet. The core samples of smaller shifts can be most simply divided into: (1) H beta-a red-shifted radio-loud population (related to the tail) acid a radio-quiet population with mean shift near zero, and (2) C IV-a blueshifted radio-quiet population (related to the tail) and a radio-loud population with mean shift near zero. The results suggest fundamentally different kinematics for the HILs and LILs. They also suggest very different kinematics for radio-loud and radio-quiet active galactic nuclei. They also favor a predominance of radial motion in a large fraction of the sample."

The protein could be purified in three days by a simple procedure which includes heat treatment, ammonium sulfate fractionation, DEAE Sephacel and ACA 44 chromatographies with a yield of 20 mg/l culture. In every respect, the recombinant enzyme was similar to plant chloroplast Fru(1,6)P(2)ase and, in particular, its reactivity with Mg2+ and redox regulatory properties were conserved. In a second series of experiments based on three-dimensional modeling of the chloroplast protein and sequence alignments, two cysteine residues of the recombinant enzyme (Cys173 and Cys178) were mutated into serine residues. An active enzyme, which did not respond to thiol reagents and to light activation, was obtained, confirming the putative regulatory role of the insertional sequence characteristic of the chloroplast enzyme."

The maps are dominated by a central source whose position coincides with eta Car. Extended millimeter continuum emission is detected both at lambda 1.3 and 2.9-mm. This emission traces the optically thin free-free emission from the gas ionized by the nearby massive luminous stars of Trumpler 16. In 1992, the flux densities of eta Car were 15.8+/-1.9 Jy at lambda 1.3-mm and 4.9+/-0.7Jy at 2.9-mm. From an analysis of the spectrum from the near-infrared to the decimeter radio range, we show that the millimeter emission of eta Car is dominated by thermal emission from the ionized stellar wind. The infrared emission is dominated by dust radiation with temperatures ranging from 200 to 400 K. The total luminosity is L(IR) = 5 10(6) L.. Based on the millimeter flux densities measured in 1992, we derive a mass-loss rate of similar to 2.4 10(-3) M.yr(-1). Measurements obtained during the time interval from 1991 to 1994 indicate strong flux density variations at both millimeter wavelengths. We suggest that these variations are related to episodic shell ejections leading to variations in the degree of ionization in the wind of eta Car."

Two main condensations are distinguished in both our single-dish and our VLA maps. The northern ammonia condensation is resolved by the VLA as an arclike structure that surrounds the east side of the star HH 34 IRS (the exciting source of the jet) and coincides in projection with Re 24, the reflection nebula associated with the infrared source IRS 5. We suggest that this ammonia structure is tracing the wall of a cavity around HH 34 IRS. Our results are in good agreement with the hypothesis that this cavity was created by the stellar wind from HH 34 IRS, indicating that along the life of the star two kinds of stellar wind might have been present: a low-collimation wind that created the cavity, and a highly collimated wind that is at the origin of the jet. A second VLA ammonia condensation coincides with Re 23, the brightest part of the are of optical nebulosity previously proposed to be tracing the western wall of a cavity that contains the jet. The inner edges of these two ammonia condensations coincide with zones of a high level of polarization of the optical emission. With the angular resolution of our VLA observations, no ammonia (1, 1) emission is detected directly associated with the star HH 34 IRS, setting an upper limit of 0.1[X(NH3)/10(-8)](-1) M. for the mass of a possible circumstellar disk. From our single-dish observations, we find that there is extended emission (similar to 3') of high-density gas, not seen with the VLA.

Soluble and volatile compounds produced by A. niger significantly decreased percentage spore germination and the hyphal length of G, mosseae on water agar. The decrease caused by volatile compounds was significantly greater when A, niger was grown on malt extract agar. Shoot dry weights of maize and lettuce plants cultivated in soil in pots, and percentage arbuscular mycorrhizal (AM) root colonization of plants grown either in sand:vermiculite tubes inoculated with G. mosseae spores or in soil in pots with soil inoculum, were unaffected by A. niger when this saprobe was inoculated 2 wk after G. mosseae. Shoot dry weights and percentage AM colonization of plants decreased when the saprobic fungus was inoculated at the same time or 2 wk before G. mosseae. However, the metabolic activity resulting from AM colonization, measured as the percentage of mycelium showing succinate dehydrogenase activity, decreased in all treatments. The population of A. niger decreased when inoculated to the rhizosphere of plants at the same time as, or 2 wk after, G, mosseae, but not when it was inoculated 2 wk before G, mosseae. Our results show that C. mosseae decreases the saprobic fungal population through its effect on the plant, whereas A. niger, by the production of soluble or volatile substances, inhibits G. mosseae in its extramatrical stage."

This radio source, HH 80 North, has been proposed to be a member of the Herbig-Haro class since its centimeter flux density, angular size, spectral index, and morphology are all similar to those of HH 80. However, no object has been detected at optical wavelengths at the position of HH 80 North, possibly because of high extinction, and the confirmation of the radio continuum source as an HH object has not been possible. In the prototypical Herbig-Haro objects HH 1 and 2, ammonia emission has been detected downstream of the how in both objects. This detection has been interpreted as a result of an enhancement in the ammonia emission produced by the radiation held of the shock associated with the HH object. In this Letter we report the detection of the (1, 1) and (2, 2) inversion transitions of ammonia downstream HH 80 North. This detection gives strong support to the interpretation of HH 80 North as a heavily obscured HH object. In addition, we suggest that ammonia emission may be a tracer of embedded Herbig-Haro objects in other regions of star formation. A 60 mu m IRAS source could be associated with HH 80 North and with the ammonia condensation. A tentative explanation for the far-infrared emission as arising in dust heated by the optical and UV radiation of the HH object is presented."

Gerdeman and Trappe, or G. intraradices Schenk and Smith. Growth, N uptake, and nutrition were evaluated in VAM-inoculated plants and controls fertilized with two levels (3 or 6 mM) of either NH4+-N or NO3--N. The response by the mycorrhizal plants to N fertilization, according to N source and/or level differed significantly from that of the control plants. In general, the growth of the mycorrhizal plants was similar to that of the non-mycorrhizal plants when N was provided as NH4+. When the N source was NO3- the control plants grew significantly less than the VAM plants. Inoculation with VAM fungi gave yield increases of 255 and 268% for G. etunicatum-colonized plants, 201 and 164% for G. mosseae-colonized plants and 286 and 218% for G. intraradices-colonized plants fertilized with 3 and 6 mM NO3--N, respectively. The increased growth and acquisition of nutrients by plants fertilized with NO3--N and inoculated with VAM shows that VAM mycelium has a capacity for NO3- absorption. The results also showed that E. poeppigiana seedlings preferred NH4+ as an N source. G. etunicatum was the most effective endophyte, not only increasing N, P, Ca, Mg, and Zn uptake in the presence of NO3- fertilizer but also P and Mg in the presence of NH4+ applications. From these results we conclude that VAM symbiosis affects N metabolism in E. poeppigiana plants and that this species can overcome limitations on the use of NO3--N by the mediation of VAM fungi."

The energetic balance between the power of the stellar wind and the measured energetic input into the surrounding gas shows that the wind is largely the dominant factor for driving the bubble. The best model for the sustained bubble is the model with conservation of energy, (nonradiative shocked stellar winds).

We present multifrequency VLA radio continuum observations of Cep A HW2, the elongated radio object believed to be associated with the most luminous (approximately 10(4) L.) source in the region. In the frequency range from 1.5 to 43 GHz, we find that its flux density increases with frequency as nu0.69, while the angular size of its major axis decreases with frequency as nu-0.57. The above frequency dependences are very close to the theoretical values of nu0.6 and nu-0.7 expected for a biconical thermal jet and make Cep A HW2 the best example known of this type of object. We suggest that Cep A HW2 is responsible for at least part of the complex outflow and excitation phenomena observed in the region.

In Experiment 1 chicks were tube-fed with a nitrogen (N)-free diet for 4 days and then with a diet based on casein. Blood samples were taken by heart puncture for amino acid (AA) analysis at hourly intervals between 0 and 6 h after a meal. In Experiments 2 and 3, chicks were tube-fed at 1.5 or 1.9 maintenance level with isoenergetic (13.1 kJ ME/g(-1) DM) semisynthetic diets of different protein quality. In Experiment 2, high protein diets (20% crude protein) based on casein (C), lupin (L), soya bean (SB), faba bean (FB), field pea (FP), vetch (V) or bitter vetch (B), as the only source of protein, were used. In Experiment 3, low protein diets (12% CP) contained SB, FP, V or B. In both experiments, a N-free diet was also given. Samples of blood were taken for AA analysis between 3 and 4 h after a meal. In Experiment 1, a post-prandial increase in aminoacidemia was found; AA levels in plasma rose quickly, reaching a peak at 1 h, remained constant until 5 h and then declined, without reaching the initial values after 6 h. Irrespective of the protein quality or the protein level of the diets, the plasma AA ratio technique was in reasonable agreement with the Protein Score procedures in identifying the two most limiting amino acids for mast diets assayed. Methionine was found to be either the first or second limiting PLA for all diets, with the exception of diet C in Experiment 2 (tryptophan and histidine, respectively)."

In this model, the stellar jet is assumed to have a large number of ''internal working surfaces'' that intercept material from the jet beam and eject it sideways into the near environment. This sideways ejection of mass and momentum leads to the formation of a ''turbulent envelope'' in which the jet material is mixed with entrained environmental gas. Under the assumption that the jet has a large number of internal working surfaces (which would probably be the case for an evolved outflow), we derive a simple theoretical framework for describing this flow. We then use this model to obtain predictions of intensity maps and position-velocity diagrams which can be directly compared with observations of molecular outflows. We also discuss the general characteristics predicted from our model, which apparently show a good qualitative agreement with observations of molecular outflows. However, our model appears to predict a somewhat too high degree of collimation for the molecular outflows.

As previously reported, the high-density gas is mainly distributed in three clumps, Cep A-1, Cep A-2, and Cep A-3. Cep A-1 and Cep A-3 constitute an interstellar elongated structure (approximately 2.'3 x 0.'4, or approximately 0.5 x 0.08 pc), with the stellar activity center located at its northwest edge. We find that Cep A-1 and Cep A-3 are located, respectively, between the two main pairs of the blue- and redshifted CO lobes of the quadrupolar molecular outflow. This implies that the interstellar disklike structure cannot collimate the bipolar outflow near its origin in the east-west direction. The high-velocity outflow and the photons of its powering source seem to be producing significant perturbations of the morphological, kinematical, and temperature structures at the edges of the ammonia condensations. We suggest that the interstellar high-density condensations are diverting and redirecting the molecular outflow at scales of approximately 0.05-0.5 pc, with Cep A-1 and Cep A-3 splitting in two halves, respectively, the blue- and redshifted lobes of an originally bipolar outflow already collimated in the east-west direction at circumstellar scales. Part of the high-density gas located at the edges of the interstellar ammonia condensations may be in the process of being incorporated into the general high-velocity molecular outflow by a dragging effect. However, the overall observed motions in the interstellar high-density gas could be bound by the observed mass in the region. HW 2 is embedded in a circumstellar (approximately 3.3 x 2.''3, or approximately 2400 x 1700 AU; pa. = 22-degrees) high-density [n(H2) congruent-to 3 x 10(7)(X(NH3)/10(-8))-1 cm-3] clump of approximately 2(X(NH3)/10(-8))-1 M.. The high rotational temperatures [T(R)(22-11) = 40-50 K] and the large velocity dispersions in the ammonia emission (sigma congruent-to 3-4 km s-1) found toward this position lead us to favor this object as the powering source of the high-velocity outflow. The observed motions of the circumstellar molecular gas could reflect the bound motions of the gas (e.g., rotation or infall) around a central mass of approximately 10-20 M., or alternatively the perturbation of the ps by the wind of the central source. This circumstellar clump could be related to the circumstellar disk previously suggested from infrared continuum and maser line observations. We find that gas temperatures as a function of the projected distance r with respect to HW 2 can be fitted by T(R)(22-11) is-proportional-to r(-alpha), with alpha = 0.3-0.6. These indices are quite similar to those expected if heating of the molecular gas is via collisions with hot dust heated by the radiation of the central star(s). The observed luminosity in the region is enough to heat the gas up to the observed temperatures. This analysis suggests that similar VLA studies of radial temperature profiles in other star-forming regions may be very useful for understanding heating processes and identifying exciting sources."

These observations suggest the presence of a ''champagne'' flow of ionized gas. We detected two extended radio continuum sources emitting optically thin free-free radiation. The stronger one [S(nu)(total) congruent-to 4 Jy] is associated with GM 24, while the weaker one [S(nu)(total) congruent-to 0.1 Jy], located approximately 1'5 south of GM 24, is related to an optical nebula in the region. The maximum of radio continuum emission coincides with the source IRAS 17136-3617, which is the core of an infrared star cluster. The spectral line data show two velocity components toward GM 24 separated by approximately 10 km s-1. The velocity of the stronger and more compact component is close to the molecular cloud velocity, while its peak of line intensity coincides with the core of the star cluster. The largest H92alpha line widths (DELTAV congruent-to 46 km s-1) are also observed toward this position. The second velocity component (the weaker and extended one) is redshifted by approximately 10 km s-1 with respect to the velocity of the ambient molecular cloud. We suggest as a possible scenario that this velocity component constitutes emission from the ionized gas which is breaking out of the cloud and expanding away from us. A water maser source, with four velocity compoments, is located approximately 15'' southwest of the peak of the radio continuum emission."

We find that the molecular condensations associated with the far-infrared sources FIR 5, FIR 6, and FIR 7 have kinetic temperatures T(K) congruent-to 40 K. We also find line broadening toward FIR 6 and FIR 7. This suggests that these condensations may not be protostars heated by gravitational energy released during collapse but that they have an internal heating source. A flattened structure of ammonia emission is found extending parallel to the unipolar CO outflow structure, but displaced systematically to the east. If the NH3 emission traces the denser gas environment, there is no evidence that a dense gas structure is confining the molecular outflow. Instead, the location of the high-velocity outflow along the surface of the NH3 structure suggests that a wind is sweeping material from the surface of this elongated cloud core."

Since this is an introductory study, we only used the examples for 5 M., 1 M., and 0.6 M.. The results obtained are: (a) The Main Sequence represents a state of minimum action and potential energy where A(c)(t) and E(p)(t) are nearly invariant when compared to the variations of any other stellar parameter such as luminosity L(t), radius R(t), or the density rho(t) on which depends alpha(t), beta(t). (b) These parameters and the time of permanence of a star in the Main Sequence are, as expected, very sensitive to X, Z. But the parameters A(c), E(p) remain minimum and nearly invariant in the Main Sequence. The contractive and expansive phases associated with the pre- and post-Main-Sequence stages are also analysed. The scenario is not fundamentally altered if one includes rotational effects, taking the possible upper limits from observed rotations in T Tauri stars. (c) As a test for the theoretical criteria used here (and as a by-product with further applications) one has that the effective dynamical density rho(eff) = alpha-3-rho (mean stellar density) leads to an effective scale time for the thermal motions in the stellar interior P(eff) is-proportional-to rho(eff)-1/2 which is consistent with oscillation periods of pulsating stars not far from the Main Sequence such as delta-Scuti and beta-Cephei. The possibilities of further studies about stellar evolution using Jacobi dynamics are discussed."

J	"QUIROGA, RJ; CLARET, A"						THE STARS IN THE MAIN-SEQUENCE AND THEIR DYNAMIC PARAMETERS	ASTROPHYSICS AND SPACE SCIENCE		English	Article							CLOUDS	"The stars in the Main Sequence are seen as a hierarchy of objects with different masses M and effective dynamical radii R(eff) = R/alpha given by the stellar radii and the coefficients for the inner structure of the stars. As seen in a previous work (Paper I), during the lifetime in the Main Sequence R(eff)(t) remains a near invariant when compared to the variation in the time of R(t) and alpha(t). With such an effective R(eff) one obtains the amounts of action A(c)(M), the effective densities rho(eff)(M) = rho(M)alpha-3(M), the densities of action and of energy (or mean pressures in the stellar interior) a(c)(M), e(c)(M), and the potential energies E(p)(M). The amounts of action are A(c) is-proportional-to M(k) with k almost-equal-to 1.87 for the M stars, k almost-equal-to 5/3 for the KGF stars, and k almost-equal-to 1.83 for the A and earlier stars, representing very simple conditions for the other dynamical parameters. For instance k almost-equal-to 5/3 means a near invariant effective density rho(eff) for the KGF stars, while for such stars the mean densities and coefficients-alpha present the strongest variations with masses rho(M) is-proportional-to M-1.81 alpha(M) is-proportional-to M0.6. The cases for the M stars (e(c)(M) is-proportional-to M-1) and for the A and earlier stars (between a(c)(M) = constant and rho(eff)(M) is-proportional-to M-1) are also discussed. These conditions for the earlier stars also represent reasonable mean values for the whole stellar hierarchy in the range of masses 0.2 M. less-than-or-equal-to M less-than-or-equal-to 25 M.. With all this, one can build 'dynamical' HR diagrams with A(c)(M), E(p)(M), rho(eff)(M), etc., whose characteristics are analogous to these in the photometrical HR diagram. A comparison is made between A(c)(M) from the models here and the HR diagram with the best known stars of luminosity classes IV, V, and white dwarfs. The comparison of the potential energies E(p)(M) is-proportional-to M(-p) according to the stellar models used here and the observed frequency function psi(M) is-proportional-to M(-q) (number of stars in a given interval of masses) from different authors suggests the possibility that the product E(p)(M)psi(M) is a constant, but this must be confirmed with further studies of the function psi(M) and its fine structure. There are analogies between the formulation used here for the stellar hierarchy and other physical processes, for instance, in modified forms of the Kolmogorov law of turbulence and in the formulation used for the hierarchy of molecular clouds in gravitational equilibrium. Besides, the function of action A(c)(M) for the stars has analogous properties to the relations of angular momenta and masses J(M) for different types of objects. The cosmological implications of all this are discussed."

The galaxy exhibits gaseous wisps broadly coincident with the radio lobes. The optical spectrum is dominated by an emission line showing a very large rest-frame equivalent width of 350 angstrom, a spatial extent of approximately 10"" at the position angle of the radio structure, and a tilt with a maximum rest-frame velocity difference of approximately 760 km s-1. These properties, as well as the presence of the optical wisps suggest that the system is a product of a merger involving a gas-rich disk and a massive elliptical. Even though the object is relatively bright (V = 21.3), additional spectral lines could only be detected after a persistent, deep integration. These very faint features, identified with H-beta, [O III] lambda-5007, and H, K and G-band, have lead to an unambiguous interpretation of the dominant emission line as being [O II] lambda-3727. The detection of faint lines may have considerable relevance to some cases of radio galaxies for which extremely large redshifts (z > 3) have been inferred recently. The red colour of the galaxy, and the equivalent widths of the stellar absorption features suggest that the continuum of 1411-192 is dominated by an old stellar population. The physical conditions of the gas are similar to those of LINERS, with shock-heating as a possible ionization mechanism. The association of an ""ultra-soft"" emission line spectrum with such a powerful radio galaxy is intriguing."

In more than 80 HII galaxies the line [OIII]-lambda-4363 was measured with accuracy good enough to permit precise electron temperature determinations.  The observational parameters that define the properties of HII galaxies as a class are characterized and discussed."

The results show that many characteristic cuticular features (form of the head, head constriction, prominence of labial disc, presence and number of longitudinal striations on basal lip annule, tail form, form of tail annules, presence of epiptygma, indentation of the bursa) are variable at specific level and cannot be used for specific characterization.  Some other characters (number of lip annules, presence of areolations at phasmid level in lateral fields, ornamentation of lateral fields) show a low variability, are relatively constant in the genus, have limited use as identification criteria at the specific level, and help to separate species into groups. Study of the morphology of the epiptygma shows that this organ has a tubular structure which can be retracted and/or coiled into the vagina or protruded from the vulva to varying degrees, appearing in lateral optical section single when flattened or double when the tube is open. The synonymy of Peltamigratus and Nectopelta with Aorolaimus is confirmed.  Eight new combinations are proposed:  A. areolatus, A. levicaudatus, A. amazonensis, A. cerradoensis, A. raskii, A. paraensis, A. vigiae, A. banoae for species originally in Peltamigratus. A. intermedius is transferred to the genus Hoplolaimus as Hoplolaimus intermedius n. comb. The 32 species of the genus are placed in three groups according to (i) phasmid position, (ii) the presence of areolations at phasmid level in the lateral field, and (iii) the type of longitudinal ornamentations in the lateral fields. Morphological differences between the genera Scutellonema and Aorolaimus are discussed."
