By regulating cellular differentiation and branching morphogenesis, vitamin A plays an essential role during lung development. Retinoic acid ...
Chronic ketamine administration impairs mitochondrial complex I in the rat liver.
Venâncio, Carlos; Antunes, Luís; Félix, Luís; Rodrigues, Paula; Summaville, Teresa; Peixoto, FranciscoAIM: Ketamine can induce hepatotoxicity which has been suggested to be dependent on mitochondrial impairment. This study investigated the long-term effects of chronic low-dose ketamine on liver mitochondrial function, oxidative stress parameters, liver histology and glycogen content. MAIN METHODS: Adult rats were administered with saline or ketamine (5 or 10mg/kg) twice a day for a fourteen-day period in orde...

Effect of gamma radiation on mycotoxins solutions
Calado, Thalita; Antonio, Amilcar L.; Rodrigues, Paula; Cabo Verde, Sandra; Venâncio, ArmandoDue to the high toxicity of mycotoxins, many methods have been used to reduce or eliminate them from food and feed. Gamma radiation is one technique that has been investigated with some promising results in degradation of some mycotoxins from food. The aim of this study was to clarify the effect of gamma irradiation on aflatoxin B1 (AFB1) aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2), ochatox...
