Molecular footprint of drug-selective pressure in a human immunodeficiency virus transmission chain
No full textKnown human immunodeficiency virus (HIV) transmission histories are invaluable models for investigating the evolutionary and transmission dynamics of the virus and to assess the accuracy of phylogenetic reconstructions. Here we have characterized an HIV-1 transmission chain consisting of nine infected patients, almost all of whom were treated with antiviral drugs at later stages of infection. Partial pol and env gp41 regions of the HIV genome were directly sequenced from plasma viral RNA for at least one sample from each patient. Phylogenetic analyses in pol using likelihood methods inferred an evolutionary history not fully compatible with the known transmission history. This could be attributed to parallel evolution of drug resistance mutations resulting in the incorrect clustering of multidrug-resistant virus. On the other hand, a fully compatible phylogenetic tree was reconstructed from the env sequences. We were able to identify and quantify the molecular footprint of drug-selective pressure in pol using maximum likelihood inference under different codon substitution models. An increased fixation rate of mutations in the HIV population of the multidrug-resistant patient was demonstrated using molecular clock modeling. We show that molecular evolutionary analyses, guided by a known transmission history, can reveal the presence of confounding factors like natural selection and caution should be taken when accurate descriptions of HIV evolution are required.</p

Previous issue date: 2007-03-30A presente disserta??o tem como linha de pesquisa Pol?tica Criminal, Estado e Limita??o do Poder Punitivo e como ?rea de concentra??o a viol?ncia. Trata da delinq??ncia na Pol?cia Civil do Rio Grande do Sul e como a mesma ? vista pela Corregedoria-Geral de Pol?cia Civil, ?rg?o de controle interno da corpora??o, atrav?s da investiga??o e da formaliza??o dos casos por meio de inqu?ritos policiais ali elaborados. A partir da an?lise dos inqu?ritos policiais instaurados e remetidos entre 1999 a 2004, pode-se obter uma s?rie de dados acerca do policial investigado (g?nero, idade, tempo de servi?o, escolaridade, cargo), em que local teria ocorrido o delito, qual (is) delito (s) ele foi acusado, quais tipos de prova foram produzidos (testemunhal, documental e pericial), bem como se a v?tima e o policial acusado tinham antecedentes policiais. Ainda, analisa-se a decis?o do delegado-corregedor, por qual fundamento tomou tal decis?o e o que ocorreu no Poder Judici?rio com os casos em que houve indiciamento. Tamb?m, visando compreender todo esse contexto, realiza-se entrevista com os delegados de pol?cia que ocuparam a fun??o de Corregedor-Geral de Pol?cia entre 1999 e 2004, al?m de um dos primeiros Corregedores do ?rg?o. No mesmo sentido, analisa-se os documentos produzidos no interior dos inqu?ritos policiais. O objetivo da pesquisa ? caracterizar que tipo de delito o policial civil comete e como ? apurado pela COGEPOL tal pr?tica, no intento de elaborar um mapeamento sobre essa pr?tica delitiva, bem como compreender como se desenvolve o trabalho da Corregedoria-Geral de Pol?cia do estado, no que tange ? produ??o de provas e se h? interfer?ncia ou n?o no trabalho por ela desenvolvido, bem como se isso repercute no Poder Judici?rio. Considerando-se os aspectos analisados, conclui-se que os policiais civis cometem delitos, via de regra, por objetivos econ?micos, tendo idade aproximada entre 35 a 49 anos, com 17 a 25 anos de atividade, e sendo a atividade externa a que mais se vincula ? pr?tica de delitos. Constata-se, ainda, que a COGEPOL ? suscet?vel a influ?ncias externas e o indiciamento de policiais ? baixo, tendo como principal prova a testemunhal

Informality Sectoral Selection and Earnings in Uruguay
No full textIn this paper we define an informal worker as one who is not contributing to the social security system. We analyze the likelihood of being an informal worker, and we estimate the differentials in earnings between sectors using the OLS estimation and a switching regression model. We find that formality is more likely among the better-educated, and among men, those residing in the capital city, and heads of households. In addition, we find that according to five different proxies of the average gap for salaried workers and several sub-samples, earnings are higher in the formal than in the informal sector for all the samples.informal sector, wage differential
Ant community patterns in highly fragmented Chaco forests of central Argentina
No full textThe Chaco is the largest dry forest biome in South America and one of the regions most threatened by agricultural intensification. As a consequence, in several areas Chaco forests persist as forest remnants of different sizes embedded in an agricultural matrix. Ants are social insects that have key roles in ecosystem functioning, and the effects of this ongoing land use change process on ant communities are little known for this region. In the present study, we assessed the consequences of land use replacement by monocultures and forest fragmentation on ant communities. Particularly, we assessed whether patch size, patch isolation and edge effect affect species richness and composition of ground-dwelling ants in fragmented landscapes of Chaco forests. We collected ants by combining hand collecting and pitfall traps in 17 forest fragments and the surrounding matrix from two sites in Córdoba, Argentina. Patch size and patch isolation had no effect on ant richness; however, patch isolation and, to a lesser extent, patch size altered ant species composition. The ant community was not affected by edge but it was negatively affected by the crop matrix, which reduced richness and altered species composition. These results indicate that monoculture matrices severely affect ant communities in the Chaco forests, and that the effects of other indicators of habitat fragmentation (patch size and edge effect) are subtler and less relevant. In the present context of land use change, even small fragments could have an important value for the conservation of ant diversity.Fil: Pereyra, Mariana.

Grass seed production in the central Monte desert during successive wet and dry years
No full textIn desert regions, water availability triggers primary production, which determines seed production, the composition and size of soil seed reserves and the abundance and behaviour of seed-eating animals. In the central Monte desert, large precipitation events (≥10 mm) account for a high proportion of growing season's rainfall. Our first objective here was to assess whether and how timing and amount of seed production of C3 and C4 perennial grasses are linked to spring and summer precipitation pulses and to estimate the seasonal and year-to-year variability in seed production. Our second aim was to calculate grass seed production and compare it with seed requirements by granivorous animals to infer whether the animals can exert top-down effects on plant populations. Seed production of C3 and C4 species was triggered by significant spring and summer rainfall, respectively. Such distinct response may be associated with the effect of precipitation during flower development and seed set in both functional groups. In all species, seed production varied among years. Rainfall pulses in the summer triggered and positively affected the magnitude of seed production in most C4 grasses. However, all perennial grasses were able to produce high amount of seeds even during a year subjected to extreme drought, suggesting that perenniality would allow these species to make large reproductive investment despite harsh environmental conditions. The comparative assessment of seed production and consumer demands suggests that it is unlikely that granivory exerts a top-down control on grasses in the Monte desert.Fil: Pol, Rodrigo Gabriel.
