Ethanol metabolism in the liver induces oxidative stress and altered cytokine production preceding myofibroblast activation and fibrogenic responses. The purpose of this study was to determine how ethanol affects the fibrogenic response in precision-cut liver slices (PCLS). PCLS were obtained from chow-fed male Wistar rats (200-300 g) and were cultured up to 96 h in medium, 25 mM ethanol, or 25...

the oxidation of complexes of ti(iii), (til6)3+ (l=ur, meur, dmeur, deture, n-bu-ur, and phur), by iodine as i3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. the enthalpy of activation appears to decrease as ligand's size increases which suggest that the kinetic stabili...

Alcohol consumption is frequently associated with various cancers and the enhancement of the metabolic activation of carcinogens has been proposed as a mechanism underlying this relationship. The ethanol-induced enhancement of N-nitrosodiethylamine (DEN)-mediated carcinogenesis can be attributed to an increase in hepatic activity. However, the mechanism of elevation of N-nitrosomethylbenzylamin...

To study the mechanism of curcumin-attenuated inflammation and liver pathology in early stage of alcoholic liver disease, female Sprague-Dawley rats were divided into four groups and treated with ethanol or curcumin via an intragastric tube for 4 weeks. A control group treated with distilled water, and an ethanol group was treated with ethanol (7.5 g/kg bw). Treatment groups were fed with ethan...

MRC Group, School of Biosciences, Cardiff University, Museum Avenue Cardiff CF10 3AX, Wales, UK. Acute pancreatitis is generally initiated by premature trypsinogen activation in pancreatic acinar cells mediated by excessive intracellular calcium release from internal stores. One of the major causes of acute pancreatitis is excessive alcohol intake, but the molecular mechanism of this severe inf...

AIMS Different epidemiological studies have demonstrated that some ethanol containing beverages intake could be associated with a reduction of cardiovascular mortality, effect attributed in part to its antioxidant properties. Nuclear factor-kappa B (NF-kappaB) is a redox sensitive transcription factor implicated in the pathogenesis of atherosclerosis. We have examined the effect of four differe...

Protein kinase C (PKC) has been shown to regulate the ethanol sensitivity of membrane-bound receptors and transporters, but little is known about the molecular mechanisms underlying this regulation. PKC is a family of isozymes that translocate to new intracellular sites on activation. Here we present immunochemical data showing that ethanol causes translocation of dand e-PKC to new intracellula...

Toll-like receptors play an important role in the innate immune response, although emerging evidence indicates their role in brain injury and neurodegeneration. Alcohol abuse induces brain damage and can sometimes lead to neurodegeneration. We recently found that ethanol can promote TLR4 signaling in glial cells by triggering the induction of inflammatory mediators and causing cell death, sugge...

Objective(s) Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the present study, we aimed to investigate the gastroprotective potential of either p...
