Aims. 3,5,4'-Trihydroxy-trans-stilbene, a natural polyphenolic compound present in wine and grapes and better known as resveratrol, has free radical scavenging properties and is a potent protector against oxidative stress induced by alcohol metabolism. Today, the mechanism by which ethanol exerts its toxicity is still not well understood, but it is(More)
BACKGROUND Prolonged opening of the mitochondrial permeability transition pore (PTP) leads to cell death. Various ubiquinone analogs have been shown to regulate PTP opening but the outcome of PTP regulation by ubiquinone analogs on cell fate has not been studied yet. METHODOLOGY/PRINCIPAL FINDINGS The effects of ubiquinone 0 (Ub(0)), ubiquinone 5 (Ub(5)),(More)
The beta-amyloid (Abeta) peptide Abeta25-35 provokes apoptosis of cerebellar granule cells through activation of caspase-3 while the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) promotes granule cell survival by inhibiting caspase-3 activation through the intrinsic apoptotic pathway. The aim of the present study was to determine(More)
The aim of this study was to characterize the early alterations of the liver mitochondrial function in ZDF (fa/fa) rats that develop diabetes compared to that of their lean counterparts ZDF (fa/+). Liver mitochondrial function was examined in 11- and 14-week-old ZDF (fa/fa) and ZDF lean (fa/+) rats. Oxygen consumption, H2O2 release, calcium retention(More)
