Ferreira, Pollyanna de Moraes França; Martins, Maria Tatiana Soares; Caldas, Débora Werneck; Gomes, Juliana Rodrigues; Oliveira, Jerusa Maria deThe aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg−1 feed. There was an increasing linear effect of turmeric on the thickness of the muscular layer, and height and width of the folds of the intestine. In...
Fertility in male rats: Disentangling adverse effects of arsenic compounds
Lima, Graziela Domingues de Almeida; Sertorio, Marcela Nascimento; Souza, Ana Cláudia Ferreira; Menezes, Tatiana Prata; Mouro, Viviane Gorete SilveiraArsenic impairs male reproductive functions. However, it is not clear whether different arsenic compounds similarly affect fertility. In this study, we compared the impact of sodium arsenite and arsenate on sperm quality and fertility. After 56 d exposure, male Wistar rats were mated and pregnant females were evaluated by fertility indexes. Clearly, exposure to 10 mg/L arsenite reduced daily sperm production vi...

Oliveira, Jerusa Maria deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Exogenous factors including heavy metals, radiation, environmental pollution, and pesticides can cause oxidative stress. Exposure to toxicants induces tissue bioacumulation and damage and has been associated with declines in bat populations. The aim of this study was to determine the occurrence of oxidative stress after a chronic exposure to commercia...
