In this study we investigated the hypothesis that a high-salt diet to hyperinsulinemic rats might impair antioxidant defense owing to its involvement in the activation of sodium reabsorption to lead to higher oxidative stress. Rats were fed a standard (CON), a high-salt (HS), or a high-fructose (HF) diet for 10 weeks after which, 50% of the animals belonging to the HF group were switched to a regimen of high-fr...
Previous studies have demonstrated that the ingestion of açaí pulp can improve serum lipid profile in various animal models; therefore, we hypothesized that açaí pulp (Euterpe oleracea Mart.) may modulate the expression of the genes involved in cholesterol homeostasis in the liver and increase fecal excretion, thus reducing serum cholesterol. To test this hypothesis, we analyzed the expression of 7α-hydroxylase...
O extrato de sementes de urucum, bastante utilizado como corante de alimentos, tem sido também descrito pela comunidade científica por seu efeito hipocolesterolemiante. Desta forma, o objetivo deste trabalho foi avaliar em ratos, os efeitos da administração de um extrato oleoso contendo 8% de bixina sobre o perfil lipídico, defesas antioxidantes e marcadores das funções hepáticas e renais. Foram conduzidos três...
