The nanocomposite consists of the Ag as a core and Pt as shell on the surface of graphene nanosheets (Ag/Pt-G) was synthesized with a simple method and used as a novel electrochemical platform for an efficient catalyst for oxidation of the ethanol, methanol and formic acid. The morphology and electrochemical properties of Ag/Pt-G nanocomposite were investigated by TEM, X-ray diffraction, and vo...

The form of liver microsomal cytochrome P-450 induced by chronic administration of ethanol to rabbits, designated as P-450ALC or P-450 isozyme 3a, has been purified to homogeneity as judged by several criteria, including NH2- and COOH-terminal amino acid sequence determination. The reconstituted alcohol-P-450 oxygenase (APO) system containing P-450ALC and NADPH-cytochrome P-450 reductase cataly...

Replacement of dietary triglycerides containing long-chain fatty acids (LCFA) by triglycerides containing medium-chain fatty acids (MCFA) markedly reduced the capacity of alcohol to produce fatty liver in rats. After 24 days of ethanol and MCFA, the increase in hepatic triglycerides was only 3 times that of controls, whereas an 8-fold rise was observed after ethanol and LCFA. The triglyceride f...

Chronic ethanol-induced downregulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α) and upregulation of peroxisome proliferator-activated receptor gamma coactivator 1-beta (PGC1β) affect hepatic lipid oxidation and lipogenesis, respectively, leading to fatty liver injury. Low-ω3 fatty acid (Low-ω3FA) that primarily regulates PGC1α and soy protein (SP) that see...

Doxorubicin is an antineoplastic drug which undergoes oxidation-reduction cycling and produces toxicity to some cancer cell lines. Since oxidation-reduction cycling requires reducing equivalents and because ethanol metabolism via alcohol dehydrogenase (ADH) increases NADH, the effect of ethanol on doxorubicin toxicity was examined in cultured cells. Since some cells exhibit resistance to anthra...

1. The influence of ethanol on the redox level of the redox pair lactate/pyruvate has been studied in experiments with rat-liver slices. 2. Ethanol had no effect on oxygen consumption but strongly depressed carbon dioxide formation. On the assumption that ethanol is oxidized to acetate in the liver slices, it could be calculated that most of the oxygen that disappeared was consumed in this reac...

In the present study, three different structures with preferentially exposed crystal faces were supported on commercial carbon black by the polyol method (nanoparticles (NP/C), nanobars (NB/C) and nanorods (NR/C)). The electrocatalysts were characterized by XRD, TEM, TGA and cyclic voltammetry at three different ethanol concentrations. Considerable differences were found in terms of catalytic e...

Porous Pt nanowire arrays show enhanced electrocatalytic activities for ethanol oxidation in direct alcohol fuel cells.
