Four populations of Astyanax hastatus Myers 1928 from the Guapimirim River basin (Rio de Janeiro State) were analyzed and three distinct cytotypes identified. These cytotypes presented 2n = 50 chromosomes, with 4M+8SM+10ST+28A (Cytotype A), 8M+10SM+14ST+18A (Cytotype B), 6M+8SM+4ST+32A (Cytotype C) and scanty heterochromatin, mainly located throughout pericentromeric regions of several chromosomal pairs. No homologies with the As-51 satellite DNA were observed in the three cytotypes, although all of them presented multiple 18S rDNA sites, as detected by both silver nitrate staining and FISH (fluorescent in situ hybridization). The application of the term "species complex" in Astyanax is discussed from a cytotaxonomic viewpoint.

Background Twin and family studies have shown that genetic effects explain a relatively high amount of the phenotypic variation in blood pressure. However, many studies have not been able to replicate findings of association between specific polymorphisms and diastolic and systolic blood pressure. Methods In a structural equation-modelling framework the authors investigated longitudinal changes in repeated measures of blood pressures in a sample of 298 like-sexed twin pairs from the population-based Swedish Twin Registry. Also examined was the association between blood pressure and polymorphisms in the angiotensin-I converting enzyme and the angiotensin 11 receptor type 1 with the 'Fulker' test Both linkage and association were tested simultaneously revealing whether the polymorphism is a Quantitative Trait Locus (QTL) or in linkage disequilibrium with the QTL. Results Genetic influences explained up to 46% of the phenotypic variance in diastolic and 63% of the phenotypic variance in systolic blood pressure. Genetic influences were stable over time and contributed up to 78% of the phenotypic correlation in both diastolic and systolic blood pressure. Non-shared environmental effects were characterised by time specific influences and little transmission from one time point to the next. There was no significant linkage and association between the polymorphisms and blood pressure. Conclusions There is a considerable genetic stability in both diastolic and systolic blood pressure for a 6-year period of time in adult life. Non-shared environmental influences have a small long-term effect Although associations with the polymorphisms could not be replicated, results should be interpreted with caution due to power considerations.

A leitura da obra de Paul Auster, desde os primeiros poemas e ensaios até à mais recente ficção, revela uma constante reflexão metalinguística e metaficcional sobre o trabalho da escrita. Auster equaciona o problema da escrita enquanto acto, permitindo ao leitor acompanhar e participar desse processo de construção. A narrativa e a linguagem intelectualizam-se, tornam-se conscientes, o que possibilita uma aproximação privilegiada ao ensino da tradução de textos literários através da própria literatura. The Invention of Solitude é como uma arte poética inspirada na experiência efectiva do sujeito, enquanto escritor e tradutor. Podemos considerá-lo um romance-manifesto em duas partes (Portrait of an Invisible Man e The Book of Memory), com especial incidência na exploração analítica da cena da escrita, utilizando a personagem-escritor e suas vivências como cobaia neste processo de auto e heteroconhecimento. A partir da análise aplicada de The Invention of Solitude, este artigo irá remeter também para os ensaios de Ernest Gellner sobre Wittgenstein em Language and Solitude, entre outros escritores que se debruçaram igualmente sobre questões ligadas à tradução literária, como Dryden, Goethe, Nietzsche, Benjamin, Ortega y Gasset e Octávio Paz.

In the work of Paul Auster (Newark, 1947 - ), we find two main themes: the sense of loss and existential drift and the loneliness of the individual fully committed to the work of writing, as if he had been confined to the book that commands his life. However, this second theme is clearly the dominant one because the character's space of solitude may include its own wandering, because this wandering is also often performed inside the four walls of a room, just like it is narrated inside the space of the page and the book. Both in his poetry, essays and fiction, Auster seems to face the work of writing as an actual physical effort of effective construction, as if the words that are aligned in the poem-text were stones to place in a row when building a wall or some other structure in stone.
