Astyanax gymnodontus (Eigenmann, 1911), new combination, a polymorphic characid fish endemic to the Rio Iguaçu basin in Southern Brazil, is redescribed. The species was originally described as belonging to the monotypic genus Psalidodon, distinguished from Astyanax by the possession of a single series o...
Cytogenetic and FISH analyses were performed in 30 Ancistrus cuiabae specimens from a bay near the town of Poconé, in the Pantanal of Mato Grosso, Brazil. The observed diploid number was 2n = 34 chromosomes for both sexes and three distinct katyotypic formulae were found, namely cytotype A (20m, 8sm, 6s...
The genetic variability of three Gymnotus species from the Caracu stream, a small tributary of the left margin of Paraná River (Brazilian upper Paraná River floodplain), was estimated with data of 17 putative allozyme loci, which were obtained by using corn starch gel electrophoresis of 10 enzymatic sy...

Several candidate gene studies have demonstrated that genetic polymorphisms in cytokine genes contribute to variations in the levels of cytokines produced and this variation may influence the occurrence and severity of complications after stem cell transplantation (HSCT). In this work we compared the ser...

La diabetes mellitus tipo 2 es una de las epidemias de mayor impacto a nivel mundial. La susceptibilidad genética constituye un importante factor de riesgo en ella, que se adiciona al efecto de los factores ambientales y al modo de vida. Explorar el papel del polimorfismo Gly1057Asp del gen IRS-2 en la ...
The causes of acquired aplastic anemia (AAA) include immunologic mechanisms and oxidative DNA damage. Glutathione S-transferase (GST) plays an important role in detoxification. In humans, GST genes encode four main clones: alpha (A), mu (M), pi (P) and theta (T). Among GST genes, GST M1 and T1 have null ...
A leucemia mielóide crônica (LMC) é uma doença proliferativa do sistema hematopoiético, caracterizada pela expansão clonal de uma célula-tronco primitiva e pluripotente denominada stem cell. Este tipo de leucemia está associado, em 90 por cento dos casos, à translocação t(9;22)(q34;q11). Essa ...
