The frequency of alcohol use among a subject population of 28 male and 60 female college students was assessed using the Student Alcohol and Drug Use Survey (STADUS). Data were also collected on personality traits as measured by the Sensation Seeking Scale V (SSSV) and the Eysenck Personality Questionnaire (EPQ). Finally, three biochemical variables were assessed: monoamine oxidase (MAO) activi...

The enantioselective oxidation of secondary alcohols represents a valuable approach for the synthesis optically pure compounds. Flavoprotein oxidases can catalyse such selective transformations by merely using oxygen as electron acceptor. While many flavoprotein preferably act on primary alcohols, FAD-containing alcohol oxidase from Phanerochaete chrysosporium was found to be able perform kinet...

The dramatic expansion of the peroxisomal compartment known to occur in the methanol-utilizing yeast Hansenula polymorpha on transfer from glucose- to methanol-containing media was shown to be accompanied by the synthesis of at least six major polypeptides that dominate the polypeptide pattern of total cell extracts analyzed by NaDodSO(4)/polyacrylamide gel electrophoresis. Two of these polypep...

The oxidant source in alcohol-induced liver disease remains unclear. NADPH oxidase (mainly in liver Kupffer cells and infiltrating neutrophils) could be a potential free radical source. We aimed to determine if NADPH oxidase inhibitor diphenyleneiodonium sulfate (DPI) affects nuclear factor-kappaB (NF-kappaB) activation, liver tumor necrosis factor-alpha (TNF-alpha) mRNA expression, and early a...

In North America, liver disease due to alcohol consumption is an important cause of death in adults, although its pathogenesis remains obscure. Despite the fact that resident hepatic macrophages are known to contribute to early alcohol-induced liver injury via oxidative stress, the exact source of free radicals has remained a mystery. To test the hypothesis that NADPH oxidase is the major sourc...

The regio- and stereospecific conversion of prochiral 4-alkylphenols by the covalent flavoprotein vanillyl-alcohol oxidase was investigated. The enzyme was active, with 4-alkylphenols bearing aliphatic side chains of up to seven carbon atoms. Optimal catalytic efficiency occurred with 4-ethylphenol and 4-n-propylphenols. These short-chain 4-alkylphenols are stereoselectively hydroxylated to the...

Objective: Alcohol is known to cause inflammation in the stomach by decreasing protective substances of gastric mucosa and increasing oxidative stress. The purpose this study was investigate anti-inflammatory effect Artemisiae Argyi Folium extract (AF) on alcohol-induced gastritis.Methods: total polyphenol flavonoid contents AF were confirmed through an vitro experiment. Radical scavenging acti...

Chemical tests for measurement of blood alcohols are the subject of much interest. particularly in legal cases, and there is a need for quick, simple and reliable assay methods. Likewise. the determinations of carboxylic acids and aldehydes are of importance in various industrial fields, but such assays are difficult to carry out. especially at low concentrations. In the past. alcohols_ have be...
