Increased plasma and hepatic TNF-alpha activity has been implicated in the pathogenesis of alcoholic liver disease (ALD). We previously reported that monocytes from alcoholic patients show enhanced constitutive as well as LPS-inducible NF-kappaB activation and TNF-alpha production. Studies in monocytes have shown that cAMP plays an important role in regulating TNF-alpha expression, and elevatio...
Cotton fibres were subjected to cleaning process and then characterized for maturity. Decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and Trichloroethene on the native fibres were carried out. The effects of these on the strength and moisture regain were investigated. The activation energies of the dyeings were also analysed with Durazol Scarlet Red 4 BAS. The r...
Jones, Michael K., Rabiha M. Itani, Hongtao Wang, Morimasa Tomikawa, I. James Sarfeh, Sandor Szabo, and Andrzej S. Tarnawski. Activation of VEGF and Ras genes in gastric mucosa during angiogenic response to ethanol injury. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G1345–G1355, 1999.—Our previous studies demonstrated that ethanol injury triggers the angiogenic response in gastric mu...
Using an antibody against 5α-reduced neurosteroids, predominantly allopregnanolone, we found that immunostaining in the CA1 region of rat hippocampal slices was confined to pyramidal neurons. This neurosteroid staining was increased following 15 min administration of 60 mm but not 20 mm ethanol, and the enhancement was blocked by finasteride and dutasteride, selective inhibitors of 5α-reductase...
Acute functional tolerance to ethanol develops during a single exposure to ethanol; it has been suggested to be a predisposing factor for the development of ethanol dependence. Genetic determinants of acute functional tolerance, as well as of ethanol dependence, have been clearly demonstrated. We describe a novel approach that uses a combination of selective breeding (to segregate genes contrib...
Microinjection of glycine into the ventral tegmental area selectively decreases ethanol consumption.
The mechanisms of ethanol addiction are not completely understood. The mesolimbic dopaminergic system is involved in many drug-related behaviors, including ethanol self-administration. The dopaminergic neurons in this system originate in the ventral tegmental area (VTA) and are under the control of GABAergic transmission. Our previous in vitro electrophysiological data indicate that glycine rec...
Platelet-derived growth factor (PDGF) is a critical regulator of cell proliferation. Because ethanol inhibits cell proliferation in vivo and in vitro, we hypothesize that ethanol-induced inhibition results from differential interference with signal transduction pathways activated by PDGF. Cultured cortical astrocytes were used to examine the effects of ethanol on PDGF-mediated signal transducti...
Interactions between ethanol and synaptic transmission mediated by gamma -amino-N-butyric acid (GABA) have been suggested to contribute to alcohol intoxication. Ethanol effects on postsynaptic GABAA receptors have been the major focus of this line of research. There is increasing evidence that ethanol potentiation of GABAergic transmission involves increased GABA release from presynaptic termin...
A bstract. Consumption of alcohol causes hyperuricemia by decreasing urate excretion and increasing its production. Our previous studies indicate that ethanol administration increases uric acid production by increasing ATP degradation to uric acid precursors. To test the hypothesis that ethanol-induced increased urate production results from acetate metabolism and enhanced adenosine triphosphat...
In this work, the characteristics of wood degradation using supercritical alcohols have been studied. Supercritical ethanol and supercritical methanol were used as solvents. The kinetics of wood degradation were analyzed using the nonisothermal weight loss technique with heating rates of 3.1, 9.8, and 14.5 °C/min for ethanol and 5.2, 11.3, and 16.3 °C/min for methanol. Three different kinetic a...
