Various forms of chemically induced liver injury and their detection by diagnostic procedures. (1/9751)

A large number of chemical agents, administered for therapeutic or diagnostic purposes, can produce various types of hepatic injury by several mechanisms. Some agents are intrinsically hepatotoxic, and others produce hepatic injury only in the rare, uniquely susceptible individual. Idiosyncrasy of the host is the mechanism for most types of drug-induced hepatic injury. It may reflect allergy to the drug or a metabolic aberation of the host permitting the accumulation of hepatotoxic metabolites. The syndromes of hepatic disease produced by drugs have been classified hepatocellular, hepatocanalicular, mixed and canalicular. Measurement of serum enzyme activities has provided a powerful tool for studies of hepatotoxicity. Their measurement requires awareness of relative specificity, knowledge of the mechanisms involved, and knowledge of the relationship between known hepatotoxic states and elevated enzyme activities.  (+info)

Quantitative aspects in the assessment of liver injury. (2/9751)

Liver function data are usually difficult to use in their original form when one wishes to compare the hepatotoxic properties of several chemical substances. However, procedures are available for the conversion of liver function data into quantal responses. These permit the elaboration of dose-response lines for the substances in question, the calculation of median effective doses and the statistical analysis of differences in liver-damaging potency. These same procedures can be utilized for estimating the relative hazard involved if one compares the liver-damaging potency to the median effective dose for some other pharmacologie parameter. Alterations in hepatic triglycerides, lipid peroxidation, and the activities of various hepatic enzymes can also be quantitiated in a dose-related manner. This permits the selection of equitoxic doses required for certain comparative studies and the selection of doses in chemical interaction studies. The quantitative problems involved in low-frequency adverse reactions and the difficulty these present in the detection of liver injury in laboratory animals are discussed.  (+info)

Toxicological findings in a fatal ingestion of methamphetamine. (3/9751)

This paper presents the case history of a fatality caused by the complications brought about by the presence of methamphetamine and ethanol. Drug concentrations are reported from samples obtained approximately 15 min after the subject was last observed to be chewing what was then believed to be gum, 3 h after the initial toxic symptoms were displayed, 6, 11, and 22 h later. The subjects conditions deteriorated over the course of this time, and he was declared dead 33 h after the initial display of toxic symptoms. The toxicological findings and concentration levels of the reported biological specimens concurred with the expected findings in a case of methamphetamine toxicity.  (+info)

Ciprofloxacin decreases the rate of ethanol elimination in humans. (4/9751)

BACKGROUND: Extrahepatic ethanol metabolism is postulated to take place via microbial oxidation in the colon, mediated by aerobic and facultative anaerobic bacteria. AIMS: To evaluate the role of microbial ethanol oxidation in the total elimination rate of ethanol in humans by reducing gut flora with ciprofloxacin. METHODS: Ethanol was administered intravenously at the beginning and end of a one week period to eight male volunteers. Between ethanol doses volunteers received 750 mg ciprofloxacin twice daily. RESULTS: A highly significant (p=0.001) reduction in the ethanol elimination rate (EER) was detected after ciprofloxacin medication. Mean (SEM) EER was 107.0 (5.3) and 96.9 (4.8) mg/kg/h before and after ciprofloxacin, respectively. Faecal Enterobacteriaceae and Enterococcus sp. were totally absent after medication, and faecal acetaldehyde production capacity was significantly (p<0.05) decreased from 0.91 (0.15) to 0.39 (0.08) nmol/min/mg protein. Mean faecal alcohol dehydrogenase (ADH) activity was significantly (p<0. 05) decreased after medication, but ciprofloxacin did not inhibit human hepatic ADH activity in vitro. CONCLUSIONS: Ciprofloxacin treatment decreased the ethanol elimination rate by 9.4%, with a concomitant decrease in intestinal aerobic and facultative anaerobic bacteria, faecal ADH activity, and acetaldehyde production. As ciprofloxacin has no effect on liver blood flow, hepatic ADH activity, or cytochrome CYP2E1 activity, these effects are probably caused by the reduction in intestinal flora.  (+info)

Acute effects of ethanol on kainate receptors with different subunit compositions. (5/9751)

Previous studies showed that recombinant homomeric GluR6 receptors are acutely inhibited by ethanol. This study examined the acute actions of ethanol on recombinant homomeric and heteromeric kainate (KA) receptors with different subunit configurations. Application of 25 to 100 mM ethanol produced inhibition of a similar magnitude of both GluR5-Q and GluR6-R KA receptor-dependent currents in Xenopus oocytes. Ethanol decreased the KA Emax without affecting the EC50 and its effect was independent of the membrane holding potential for both of these receptors subtypes. Ethanol also inhibited homomeric and heteromeric receptors transiently expressed in human embryonic kidney (HEK) 293 cells. In these cells, the expression of heteromeric GluR6-R subunit-containing receptors was confirmed by testing their sensitivity to 1 mM alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid. Ethanol inhibited to a similar extent KA-gated currents mediated by receptors composed of either GluR6 or GluR6 + KA1 subunits, and to a slightly lesser extent receptors composed of GluR6 + KA2 subunits. Acute ethanol's effects were tested on GluR5 KA receptors that are expressed as homomers (GluR5-Q) or heteromers (GluR5-R + KA1 and GluR5-R + KA2). Homomeric and heteromeric GluR5 KA receptors were all inhibited to a similar extent by ethanol; however, there was slightly more inhibition of GluR5-R + KA2 receptors. Thus, recombinant KA receptors with different subunit compositions are all acutely inhibited to a similar extent by ethanol. In light of recent reports that KA receptors regulate neurotransmitter release and mediate synaptic currents, we postulate that these receptors may play a role in acute ethanol intoxication.  (+info)

Ethanol exposure differentially alters central monoamine neurotransmission in alcohol-preferring versus -nonpreferring rats. (6/9751)

Individual differences in ethanol preference may be linked to differences in the functional activity of forebrain monoamine systems or their sensitivity to modification by ethanol. To test this hypothesis, basal extracellular concentrations of dopamine (DA) and serotonin (5-HT) in the nucleus accumbens as well as the effects of repeated ethanol pretreatment on the basal release of these transmitters were examined in alcohol-preferring (P), alcohol-nonpreferring (NP), and genetically heterogeneous Wistar rats. All animals received i.p. injections of ethanol (1.0 g/kg) or saline for 5 consecutive days. Fifteen hours after the final pretreatment, basal extracellular concentrations and "in vivo extraction fraction" values for DA and 5-HT were determined by no-net-flux in vivo microdialysis. In ethanol-naive rats, significant line differences were observed with high basal 5-HT release in P rats, low 5-HT release in NP rats, and intermediate 5-HT levels in Wistar rats. No differences among groups were noted in basal DA release. Ethanol pretreatment decreased basal extracellular 5-HT levels in P rats whereas increasing 5-HT efflux was seen in the Wistar and NP lines. In addition, ethanol pretreatment increased extracellular DA concentrations in Wistar and P rats, but not in NP rats. The results confirm a relationship between the functional status of forebrain DA and 5-HT systems and ethanol preference or aversion. Moreover, the data suggest that ethanol exposure can alter basal DA and 5-HT in the nucleus accumbens and that vulnerability to ethanol-induced changes in monoamine neurotransmission may be a factor in genetically determined ethanol preference.  (+info)

Isocitrate lyase of Ashbya gossypii--transcriptional regulation and peroxisomal localization. (7/9751)

The isocitrate lyase-encoding gene AgICL1 from the filamentous hemiascomycete Ashbya gossypii was isolated by heterologous complementation of a Saccharomyces cerevisiae icl1d mutant. The open reading frame of 1680 bp encoded a protein of 560 amino acids with a calculated molecular weight of 62584. Disruption of the AgICL1 gene led to complete loss of AgIcl1p activity and inability to grow on oleic acid as sole carbon source. Compartmentation of AgIcl1p in peroxisomes was demonstrated both by Percoll density gradient centrifugation and by immunogold labeling of ultrathin sections using specific antibodies. This fitted with the peroxisomal targeting signal AKL predicted from the C-terminal DNA sequence. Northern blot analysis with mycelium grown on different carbon sources as well as AgICL1 promoter replacement with the constitutive AgTEF promoter revealed a regulation at the transcriptional level. AgICL1 was subject to glucose repression, derepressed by glycerol, partially induced by the C2 compounds ethanol and acetate, and fully induced by soybean oil.  (+info)

Antisense RNA strategies for metabolic engineering of Clostridium acetobutylicum. (8/9751)

We examined the effectiveness of antisense RNA (as RNA) strategies for metabolic engineering of Clostridium acetobutylicum. Strain ATCC 824(pRD4) was developed to produce a 102-nucleotide asRNA with 87% complementarity to the butyrate kinase (BK) gene. Strain ATCC 824(pRD4) exhibited 85 to 90% lower BK and acetate kinase specific activities than the control strain. Strain ATCC 824(pRD4) also exhibited 45 to 50% lower phosphotransbutyrylase (PTB) and phosphotransacetylase specific activities than the control strain. This strain exhibited earlier induction of solventogenesis, which resulted in 50 and 35% higher final concentrations of acetone and butanol, respectively, than the concentrations in the control. Strain ATCC 824(pRD1) was developed to putatively produce a 698-nucleotide asRNA with 96% complementarity to the PTB gene. Strain ATCC 824(pRD1) exhibited 70 and 80% lower PTB and BK activities, respectively, than the control exhibited. It also exhibited 300% higher levels of a lactate dehydrogenase activity than the control exhibited. The growth yields of ATCC 824(pRD1) were 28% less than the growth yields of the control. While the levels of acids were not affected in ATCC 824(pRD1) fermentations, the acetone and butanol concentrations were 96 and 75% lower, respectively, than the concentrations in the control fermentations. The lower level of solvent production by ATCC 824(pRD1) was compensated for by approximately 100-fold higher levels of lactate production. The lack of any significant impact on butyrate formation fluxes by the lower PTB and BK levels suggests that butyrate formation fluxes are not controlled by the levels of the butyrate formation enzymes.  (+info)

Author(s): Echevarria, David J.; Hammack, Catherine M.; Jouandot, David J.; Toms, Christina N. | Abstract: Previous research reports that acute alcohol exposure disrupts shoaling behavior in the zebrafish. The purpose of these studies is to better understand how acute alcohol exposure (0%, 0.125%, 0.25%, 0.5%, and 1.0%) alters zebrafish behavior. The effects of alcohol on aggressive behaviors in humans have been widely researched. Previous research from this lab has shown a bimodal effect of alcohol on shoaling behavior in zebrafish, with 0.5% and 2.0% (v/v) disrupting shoaling while 1.0% and 1.5% showing no direct effect. Because shoaling is a social behavior and is altered during acute alcohol exposure, aggressive behavior between fish should be addressed. In this series of experiments we explored alcohols effects on aggressive behaviors. In order to address a possible role for alcohol induced aggression as it relates to shoaling we chose to examine the effects of acute alcohol exposure on zebrafish

N-methyl-D-aspartate receptor dysfunction has been strongly suggested to link with the abnormalities seen in fetal alcohol syndrome. Thus, the effects of prenatal ethanol exposure on the total expression of NR1 splice variants and the cell surface expression of both NR1 and NR2 subunits in brain were investigated in rats. Western blot studies of membrane homogenates from cerebral cortices at postnatal days 1 through 21 indicate that prenatal ethanol treatment does not alter total NR1 expression or differential expression of NR1 splice variants during development. However, immunoprecipitation studies using PSD95 suggest that both C2-terminal variants and NR2A subunits at the cortical postsynaptic membrane of postnatal day 21 were significantly reduced after prenatal ethanol treatment. Moreover, C1-terminal variants were decreased in both pair-fed and ethanol-treated groups, while no significant differences in the levels of total NR1 subunits, NR1 splice variants containing the N- or C2-terminal
Chronic intermittent ethanol vapor exposure (CIE) in rodents produces reliable and high blood ethanol concentration and behavioral symptoms associated with moderate to severe alcohol use disorder (AUD)—for example, escalation of operant ethanol self-administration, a feature suggestive of transition from recreational to addictive use, is a widely replicated behavior in rats that experience CIE. Herein, we present evidence from a subset of rats that do not demonstrate escalation of ethanol self-administration following seven weeks of CIE. These low responders (LR) maintain low ethanol self-administration during CIE, demonstrate lower relapse to drinking during abstinence and reduced reinstatement of ethanol seeking triggered by ethanol cues when compared with high responders (HR). We examined the blood ethanol levels in LR and HR rats during CIE and show higher levels in LR compared with HR. We also examined peak corticosterone levels during CIE and show that LR rats have higher levels compared

Emerging evidence suggested mitophagy activation mitigates ethanol-induced liver injury. However, the effect of ethanol on mitophagy is inconsistent. Importantly, the understanding of mitophagy status after chronic ethanol consumption is limited. This study evaluated the effect of quercetin, a naturally-occurring flavonoid, on chronic ethanol-induced mitochondrial damage focused on mitophagy. An ethanol regime to mice for 15 weeks (accounting for 30% of total calories) led to significant mitochondrial damage as evidenced by changes of the mitochondrial ultrastructure, loss of mitochondrial membrane potential and remodeling of membrane lipid composition, which was greatly attenuated by quercetin (100 mg/kg.bw). Moreover, quercetin blocked chronic ethanol-induced mitophagy suppression as denoted by mitophagosomes-lysosome fusion and mitophagy-related regulator elements, including LC3II, Parkin, p62 and voltage-dependent anion channel 1 (VDAC1), paralleling with increased FoxO3a nuclear translocation.

Title: CYP2E1: Biochemistry, Toxicology, Regulation and Function in Ethanol-Induced Liver Injury. VOLUME: 3 ISSUE: 6. Author(s):Irina Kessova and Arthur I. Cederbaum. Affiliation:Department of Pharmacology and Biological Chemistry, Box 1603, Mount Sinai Schoolof Medicine, One Gustave L. Levy Place, New York, NY 10029.. Keywords:cyp2e1, ethanol-induced liver injury, chronic alcohol treatment., cyp2e1-dependent oxidative stress. Abstract: Ethanol-induced oxidative stress appears to play a major role in mechanisms by which ethanol causes liver injury. Many pathways have been suggested to contribute to the ability of ethanol to induce a state of oxidative stress. One central pathway appears to be the induction of the CYP2E1 form of cytochrome P450 enzymes by ethanol. CYP2E1 is of interest because of its ability to metabolize and activate many toxicological substrates, including ethanol, to more reactive, toxic products. Levels of CYP2E1 are elevated under a variety of physiological and ...
Acute alcohol use is associated with impaired immune responses and decreased proinflammatory cytokine production. Our earlier studies have shown that acute alcohol intake inhibits NF-kappaB DNA binding in an IkappaBalpha-independent manner. We report using human peripheral blood monocytes and Chinese hamster ovary cells transfected with CD14 cells that acute alcohol treatment in vitro exerts NF-kappaB inhibition by disrupting phosphorylation of p65. Immunoprecipitation of p65 and IkappaBalpha revealed that acute alcohol exposure for 1 h decreased NF-kappaB-IkappaBalpha complexes in the cytoplasm. Phosphorylation of p65 at Ser(536) is mediated by IkappaB kinase (IKK)beta and is required for NF-kappaB-dependent cellular responses. We show that acute alcohol treatment decreased LPS-induced IKKalpha and IKKbeta activity resulting in decreased phosphorylation of p65 at Ser(536). Furthermore, nuclear expression of IKKalpha increased after alcohol treatment, which may contribute to inhibition of NF-kappaB.

4-Methyl pyrazole (4-MP, a specific inhibitor of alcohol dehydrogenase) reduced ethanol elimination by 30-50% and completely removed the ethanol-induced inhibition of galactose elimination in 2 control subjects. Ethanol elimination was accelerated in 2 alcoholics with adequate nutrition, but the effect of 4-MP was comparable to that in controls. In 2 other alcoholic subjects, who reported poor nutritional intake, intermediate rates of ethanol elimination were observed and 4-MP had almost no effect on ethanol or galactose elimination. These results suggest that alcohol abuse may result in an increased contribution to ethanol elimination by pathways other than that involving alcohol dehydrogenase (ADH) and that the decreased contribution from ADH, possibly potentiated by inadequate nutrition, may diminish the ethanol-induced shift in the NAD-coupled redox state. Since liver damage produced by alcohol abuse is believed to be related to changes from the normal redox state caused by ethanol, these ...
Rates of exchange catalysed by alcohol dehydrogenase were determined in vivo in order to find rate-limiting steps in ethanol metabolism. Mixtures of [1,1-2H2]- and [2,2,2-2H3]ethanol were injected in rats with bile fistulas. The concentrations in bile of ethanols having different numbers of 2H atoms were determined by g.l.c.-m.s. after the addition of [2H6]ethanol as internal standard and formation of the 3,5-dinitrobenzoates. Extensive formation of [2H4]ethanol indicated that acetaldehyde formed from [2,2,2-2H3]ethanol was reduced to ethanol and that NADH used in this reduction was partly derived from oxidation of [1,1-2H2]ethanol. The rate of acetaldehyde reduction, the degree of labelling of bound NADH and the isotope effect on ethanol oxidation were calculated by fitting models to the found concentrations of ethanols labelled with 1-42H atoms. Control experiments with only [2,2,2-2H3]ethanol showed that there was no loss of the C-2 hydrogens by exchange. The isotope effect on ethanol ...

Experiments were designed in this study to determine the subcellular location of the retained secretory proteins. Ethanol was administered acutely to nonfasted rats by gastric intubation, whereas control animals received an isocaloric dose of glucose. Two hours after intubation, when maximum blood ethanol levels (45 mM) were observed, [3H]leucine and [14C]fucose were injected simultaneously into the dorsal vein of the penis. The labeling of secretory proteins was determined in the liver and plasma at various time periods after label injection. Ethanol treatment decreased the secretion of both leucine- and ...
TY - JOUR. T1 - The effect of diet on ethanol withdrawal symptomatology. AU - Baker, T. B.. AU - Cannon, D. S.. AU - Berman, Robert F. AU - Atkinson, C. A.. PY - 1977. Y1 - 1977. N2 - In Experiment 1 rats were gavaged with ethanol and nutrients at 6 hr intervals for 72 hr. Ethanol dosages were assigned by behavioral criteria of inebriation. Nourished animals were able to tolerate higher ethanol dosages than nutrient-deprived rats (9.62 vs 7.60 g/kg/day). Nourished rats were less likely to have withdrawal seizures than were nutrient-deprived rats given an equivalent amount of ethanol, but nourished rats given 25-30% more ethanol than the nutrient-deprived rats did have withdrawal seizures. Nutrient-deprived rats had BECs (Blood Ethanol Contents) higher than those of nourished rats receiving equivalent amounts of ethanol but comparable to the BECs of nourished rats receiving 25-30% more ethanol. All these results were replicated in Experiment 2 in which ethanol dependent rats above starting body ...
TY - JOUR. T1 - Stable histone methylation changes at proteoglycan network genes following ethanol exposure. AU - Gavin, David P.. AU - Hashimoto, Joel G.. AU - Lazar, Nathan H.. AU - Carbone, Lucia. AU - Crabbe, John Jr. AU - Guizzetti, Marina. PY - 2018/8/30. Y1 - 2018/8/30. N2 - Alcohol use disorder (AUD) is a chronic mental illness in which patients often achieve protracted periods of abstinence prior to relapse. Epigenetic mechanisms may provide an explanation for the persisting gene expression changes that can be observed even after long periods of abstinence and may contribute to relapse. In this study, we examined two histone modifications, histone 3 lysine 4 tri-methylation (H3K4me3) and histone 3 lysine 27 tri-methylation (H3K27me3), in the prefrontal cortex of Withdrawal Seizure Resistant (WSR) mice 21 days after 72 h of ethanol vapor exposure. These histone modifications were selected because they are associated with active promoters (H3K4me3) and repressed gene expression in a ...
Increasing evidence suggests that ethanol-induced changes in cyclic AMP (cAMP) signal transduction play a critical role in the acute and chronic effects of ethanol. Here we have investigated the effects of ethanol on cAMP signal transduction in primary cultures of rat hepatocytes. Acute exposure to ethanol had a biphasic effect on glucagon-receptor-dependent cAMP production in intact cells: 25-50 mM-ethanol decreased cAMP, whereas treatment with 100-200 mM-ethanol increased cAMP. After chronic exposure to 50-200 mM-ethanol for 48 h in culture, glucagon-receptor-dependent cAMP levels were increased, but no change in glucagon receptor number was observed. These effects of ethanol were independent of ethanol oxidation. Chronic ethanol treatment also increased adenosine-receptor- and forskolin-stimulated cAMP production. Increased cAMP production was also observed upon stimulation of adenylate cyclase with glucagon, forskolin and F- in membranes isolated from cells cultured with 100 mM-ethanol for ...
We previously reported that ethanol elicits an increased protein oxidation in the liver of rats receiving chronic ethanol by continuous intragastric infusion (Tsukamoto-French method). This accumulation of oxidized proteins could result from a decrease in the cytosolic proteolysis, related specifica …

TY - JOUR. T1 - Responses of cerebral arterioles during chronic ethanol exposure. AU - Mayhan, William. PY - 1992. Y1 - 1992. N2 - The purpose of this study was to examine the effects of ethanol exposure on responses of cerebral arterioles in vivo. Rats were fed liquid diets with or without ethanol for 2-3 mo. Using intravital microscopy, we measured diameter of cerebral arterioles in non-ethanol- and ethanol-fed rats in response to acetylcholine, histamine, ADP, the thromboxane analogue (U- 46619), and nitroglycerin. In non-ethanol-fed rats, acetylcholine, histamine, and ADP produced dose-related dilatation of cerebral arterioles. In ethanol- fed rats, however, acetylcholine produced vasoconstriction, and vasodilatation in response to histamine and ADP was impaired. Dilatation of cerebral arterioles in response to nitroglycerin and vasoconstriction in response to the thromboxane analogue (U-46619) were similar in non-ethanol- fed and ethanol-fed rats. Thus these findings suggest that chronic ...
On July 31, 2013, INEOS Bio, a bioenergy company, announced that its Florida facility became the world pioneer in producing commercial-scale cellulosic ethanol. Ethanol, or ethyl alcohol, is a renewable fuel resulting from fermenting plant-based materials. INEOS Bio produces cellulosic ethanol using vegetative and yard waste. Despite the flurry that accompanied last Julys event, Brazil is still regarded as the country that implemented the most successful ethanol industry in the world -the sugarcane ethanol industry. In the United States, the ethanol industry touches on two critical areas. First, ethanol can be used as motor fuel, and it is no secret that the United States relies on motor fuel. Second, the nations reliance on motor fuel, especially gasoline, raises significant environmental concerns, notably, greenhouse gas (GHG) emissions. Thus, given the recent advancements in ethanol production, and the critical areas that ethanol touches on, an issue emerges as to whether Brazils ethanol ...
It is concluded that oxaloacetate, required for the incorporation of ethanol into citrate, arises mainly from the transamination of aspartate and the fixation of carbon dioxide. 1. The pathway of ethanol metabolism in cotyledons of 3-day-old pea seedlings has been examined by incubating tissue slices with [1-(14)C]ethanol and [2-(14)C]ethanol for periods up to 1hr. 2. Ethanol was rapidly incorporated into citrate and glutamate but relatively small amounts of (14)C were present in the evolved carbon dioxide even after 1hr. of ethanol metabolism. 3. Similar data were obtained from experiments in which [1,2-(14)C(2)]acetaldehyde and [(14)C]acetate were supplied. 4. The results are interpreted as indicating that ethanol is metabolized essentially via the reactions of the tricarboxylic acid cycle with a substantial drain of alpha-oxoglutarate to support the biosynthesis of glutamate. 5. It is concluded that oxaloacetate, required for the incorporation of ethanol into citrate, arises mainly from the
Author(s): Devineni, Anita | Advisor(s): Heberlein, Ulrike | Abstract: Ethanol is one of the most widely used and abused drugs in the world. Ethanol consumption produces short-term changes in behavior as well as long-term adaptations that can lead to addiction. The mechanisms underlying both acute and chronic responses to ethanol are still not fully understood. Human and rodent studies have suggested that acute ethanol sensitivity may be related to risk of alcohol abuse, and that the same genes often regulate both types of behavior. In this thesis I have used the fruit fly Drosophila melanogaster as a model to study the genetic and neural mechanisms underlying ethanol-induced behavior. In Chapter 2, I show that flies prefer to consume food containing ethanol and that this ethanol preference may represent a new model for studying addiction-related behavior. In Chapter 3, I examine the relationships between acute ethanol sensitivity, ethanol tolerance, and ethanol consumption preference by measuring these
The liver plays a key role in the metabolism of alcohol and is also sensitive to the deleterious effects of chronic alcohol consumption. In humans, chronic alcohol consumption leads to a characteristic set of changes to the metabolism of lipids in the liver that is referred to as an alcoholic fatty liver. In humans, AFL is characterized by an increase in liver weight, accumulation of triglyceride and changes in the expression of genes involved in lipid metabolism. In severe cases, these metabolic changes result in the enlargement and fibrillization of the liver and are considered risk factors for cirrhosis and liver cancer.. Previous work suggests that there may be links between mutations in the circadian system and liver metabolism. The transcription of many genes in liver, including those involved in lipid metabolism, is regulated on the circadian time scale [8, 22]. Furthermore, mice with mutations in core elements of the circadian timing system also exhibit deficits in liver function. In ...
Background: Although the beneficial effects of mild to moderate ethanol consumption have been implied with respect to heart, alcohol abuse has proven to be a major cause of nonischemic cardiomyopathy in Western society. However, the biochemical and molecular mechanisms, which mediate the pathologic cardiac effects of ethanol, remain largely unknown. The aim of the present study was to explore the effects of chronic ethanol exposure on cardiac apoptosis and expression of some of the genes associated with cardiac remodeling in vivo. Methods: Alcohol-avoiding Alko Non Alcohol rats of both sexes were used. The ethanol-exposed rats (females, n= 6; males, n= 8) were given 12% (v/v) ethanol as the only available fluid from age of three to 24 months of age. The control rats (females, n= 7; males, n= 5) had only water available. At the end of the experiment, free walls of left ventricles of hearts were immediately frozen. Cytosolic DNA fragmentation, reflecting apoptosis, was measured using a commercial ...
Detroit Public Television (DPTV) is debuting a new ethanol documentary this Sunday, October 9, 2016 at 9:00 pm ET called, The Ethanol Effect. The film, produced by DPTV, takes a look at the controversy surrounding the challenges of the best use for Americas corn production: food or biofuel. The worldwide premier of the documentary is on PBS World Channel. (Click here to view promo clips and for additional air times.). The Ethanol Effect delves into what Ethanol is, demonstrates the production process and investigates the human, environmental and political costs of growing and refining corn for fuel in America. The documentary also dives into why the choices between food or biofuel are sparking controversy across the country. Interestingly, I met the production crew this past January in Altoona, Iowa during the Iowa Renewable Fuels Summit where they had access to various speakers including Iowa Governor Terry Branstad, USDA Ag Secretary Tom Vilsack, presidential hopefuls, and more biofuel ...
Your ethanol or alcohol or drinking alcohol as it is also called can provide great taste and strength only when you use the right yeast for fermentation, and infusing top quality ethanol yeast can increase ethanol yield as well as provide that perfect taste. Whether you engage in professional ethanol production or want to ferment a small batch of ethanol at home, using the best yeast can certainly improve the quality and quantity of your end product.. Alcohols and spirits such as whiskey, beer, wine, vodka, rum, etc need to pass through several brewing and even distilling processes before they end up in your glass. These processes start by firstly mixing the raw materials such as wheat, barley, corn, sugar, potatoes, grapes, apples, or any other ingredient based on the country where the drinks are produced and the end product that is required, along with water. This mixture is boiled, milled, and cooled so as to encourage the activation of enzymes that convert all possible starch in the raw ...
The purpose of this study was to investigate the effect of protein and dietary fiber levels on the activities of ehanol metabilizing enzymes of the brain in acute and chronic ethanol-treated rats. Male Sprague-Dwley rats were fed on diets containing two levels of protein(7%, 20%)) with two levels of fiber(5%, 105) for 5 weeks. Rats were orally administered 40% (v/v) ethanol(5g/body weight) 90 min before decapitation in the acute ethanol-treated groups and 25% (v/v) ethanol (5g/kg body weight) once a day for 5 weeks in the chronic ethnol-treated groups. Cytosilic alcohol dehydrogenase (ADH) activities were higher than those of mitochondrial ADH. The ADH activities were increased by 20% protein and %% fiber levels in the diet in two fractions , but were decreased by chronic ethanol treatment. Mitochondrial aldehyde dehydrogenase (ALDH) activities did not change by ethanol treatment but were increased by the 20% protein level. However, cytosilic ALDH activities were decreased by chronic ethanol ...
The present article provides an up-to-date review summarizing almost 18 years of research in genetically selected Marchigian Sardinian alcohol-preferring (msP) rats. The results of this work demonstrate that msP rats have natural preference for ethanol characterized by a spontaneous binge-type of drinking that leads to pharmacologically significant blood ethanol levels. This rat line is highly vulnerable to relapse and presentation of stimuli predictive of alcohol availability or foot-shock stress can reinstate extinguished drug-seeking up to 8 months from the last alcohol experience. The msP rat is highly sensitive to stress, shows an anxious phenotype and has depressive-like symptoms that recover following ethanol drinking. Interestingly, these animals have an up-regulated corticotrophin releasing factor (CRF) receptor 1 system. Clinical studies have shown that alcoholic patients often drink ethanol in the attempt to self-medicate from negative affective states and to search for anxiety ...
Thus, cellulosic ethanol provides a unique opportunity in which ethanol is produced not from corn that otherwise is used as food, but from a range of waste biomass, which are normally wasted anyway.. In theory, cellulosic ethanol sounds great. In practice however, cellulosic ethanol has not entered large scale commercial production owing to the high cost of ethanol thus produced. It is hoped that the cellulosic ethanol companies will soon escape from the valley of death phase they are currently in and start producing ethanol from cellulose in a large scale. Ethanol from cellulose raises the interesting question of whether algae could be used as the biomass for ethanol production from cellulose? It appears that some species of algae do have the potential to be considered as a cellulosic feedstock for ethanol production. However, we have not seen many efforts taken in this area of research. In algae, the storage component is starch and the cell wall component is cellulose. Many strains of algae ...
Separately, chronic alcohol ingestion and HIV-1 infection are associated with severe skeletal muscle derangements, including atrophy and wasting, weakness, and fatigue. One prospective cohort study reported that 41% of HIV-infected patients met the criteria for alcoholism, however; few reports exist on the co-morbid effects of these two disease processes on skeletal muscle homeostasis. Thus, we analyzed the atrophic effects of chronic alcohol ingestion in HIV-1 transgenic rats and identified alterations to several catabolic and anabolic factors. Relative plantaris mass, total protein content, and fiber cross-sectional area were reduced in each experimental group compared to healthy, control-fed rats. Alcohol abuse further reduced plantaris fiber area in HIV-1 transgenic rats. Consistent with previous reports, gene levels of myostatin and its receptor activin IIB were not increased in HIV-1 transgenic rat muscle. However, myostatin and activin IIB were induced in healthy and HIV-1 transgenic rats fed

This dissertation examines the corn based ethanol industry in the Corn Belt of the U.S. from three different angles: What affects ethanol plant location decisions, how does new ethanol capacity affect the local corn price, and what is the future landscape of ethanol production under an uncertain future? Ethanol production is a significant part of the American economy in terms of market demand for corn, job creation, household income, tax revenue, and decreasing reliance on foreign fuel. The EPA has supported the ethanol industry through the creation of the Renewable Fuels Standards put in place in 2007, however the very mandate created in part to secure the future of renewable energy in the U.S. is also a source of uncertainty. In late 2015, after speculation of a reduction in the requirement for ethanol, the RFS were renewed at an increased ethanol mandate than expected. These three papers enhance general understanding of how ethanol growth may occur, how new ethanol capacity affects local corn ...
Purpose: : To compare the mRNA expression of IL-1α, IL-8, MCP-1, and TGF-ß1 following topical ethanol treatment and mechanical debridement. Methods: : Fifty-eight pigmented rabbit corneas were divided into four groups. Group I (n=18) received mechanical epithelial debridement, group II (n=18) underwent 20% ethanol application for 30 seconds, and group III corneas underwent 20% ethanol application for 60 seconds. Group IV (n=4) did not undergo any procedure. Corneal epithelial and stromal keratocyte change was examined with H&E and TUNEL stains, while the mRNA expression of IL-1α, IL-8, MCP-1, and TGF-ß1 were examined with real-time polymerase chain reaction (PCR). Results: : Stromal keratocyte apoptosis was noticed for three days in group I and up to seven days in group III. Topical ethanol induced significant TUNEL staining of corneal epithelium and stromal keratocyte in an application time dependent manner. In group I, the expression of IL-8 mRNA showed two spikes of up-regulation on day 0 ...
Alcoholic liver disease (ALD) results from alcohol overconsumption and is among the leading causes of liver-related morbidity and mortality worldwide. Elevated expression of vascular endothelial growth factor (VEGF) and its receptors has been observed in ALD, but how it contributes to ALD pathophysiology is unclear. Here we investigated the impact of VEGF signaling inhibition on an established zebrafish model of acute alcoholic liver injury. VEGF-receptor 2/Kdrl activity was blocked by chemical inhibitor treatment or by genetic mutation. Exposing 4-day-old zebrafish larvae to 2% ethanol for 24 hours induced hepatic steatosis, angiogenesis and fibrogenesis. The liver started self-repair once ethanol was removed. While inhibiting Kdrl did not block the initial activation of hepatic stellate cells during ethanol treatment, it suppressed their proliferation, extracellular matrix protein deposition, and fibrogenic gene expression after ethanol exposure, thus enhancing the liver repair. It also ...
Until the Daniels Administration began pushing for development of ethanol plants in 2005, Indiana had only one commercial ethanol plant that produced ethanol primarily for use in blending with petroleum products in gasoline. Indiana was barely a blip on the radar screen in the ethanol industry nationwide. Now with 13 plants producing 1.2 billion gallons of ethanol annually, Indiana is a player, and is quickly being recognized as a major player in the ethanol energy game. Pence believes part of the solution is giving consumers choices. That means making various blends of ethanol available, and will require investment by different groups at various levels. Like Governor Daniels he also believes there is still hope for cellulosic ethanol. Daniels told the same audience Pence addressed that developments in cellulosic ethanol were coming much slower than he had hoped, and many had anticipated. Nevertheless, Daniels believes it will become a player in the industry. Cellulosic ethanol refers to ethanol ...
The isolated perfused rat kidney was used to investigate the effect of ethanol on the renal excretion and metabolism of choline. Choline at an initial perfusate concentration of 2.8 mM, with tracer amounts of [methyl-14C]choline, was recirculated through kidneys and radioactivity measured in perfusate, urine, and kidney. 14C-Choline and its metabolites were identified by chromatographic and electrophoretic procedures. Tubular excretion of choline was demonstrated and a transport maximum (Tm) of 1.6 mumol/kidney/min was reached at a choline perfusate concentration of 1.2 mM. Addition of 50 mM ethanol resulted in a 56% increase in the choline Tm and 100 mM ethanol decreased the choline Tm by 25%. The rate of loss of 14C-choline from the perfusate was increased by the lower ethanol concentration and decreased by the higher ethanol concentration. Ethanol at both concentrations diminished the amount of 14C remaining in the kidney. 14C-Betaine was the major choline metabolite and the only ...
The processing of raw cannabis plants to extract cannabinoids and other compounds can be carried out using a variety of methods. Some of the most popular methods are extraction using CO2, a hydrocarbon (usually butane), or ethanol. Which one is used depends on a variety of factors, including the amount of raw material to be processed, and the final application of the product, for example what form it will take and whether its for recreational or medicinal use.. In this article, well focus on the method of ethanol extraction. Ethanol extraction can be carried out by a number of methods including cold, warm, or room-temperature processing. Some ethanol extraction processes involve the use of a rotary evaporator setup to remove the ethanol from the extract solution.. Here, we take a closer look at ethanol extraction for cannabis applications, with a particular focus on ethanol removal using a rotary evaporator. Well include information about the steps involved in ethanol extraction, optimal ...
Effect of chronic alcohol consumption on the red blood cell count and RBC indices in the HIV infected patients on d4T/3TC/NVP drug regimen in Uganda
Ibdahs research team used rats bred for high activity, or runner rats, to test if increased metabolism protected the liver against fatty deposits and inflammation. One group of rats was exposed to chronic alcohol use for six weeks and compared to a second group that was not exposed to alcohol during the same time period.. As expected, we found that fatty deposits were greater in the livers of the chronic alcohol group, said Ibdah, who also serves as director of the Division of Gastroenterology and Hepatology at the MU School of Medicine. However, chronic alcohol ingestion did not cause significant inflammation in the liver. Higher physical activity levels seemed to protect against the metabolic dysfunction that eventually leads to irreversible liver damage.. Ibdahs team also found that chronic alcohol ingestion caused no discernable increase in free fatty acids, triglycerides, insulin or glucose in the blood of the group exposed to alcohol as compared to the control group.. This is ...
Most of ethanol production processes are limited by lower ethanol production rate and recyclability problem of ethanologenic organism. In the present study, immobilized co-fermenting Saccharomyces cerevisiae GSE1618 was employed for ethanol fermentation using rice straw enzymatic hydrolysate in a packed bed reactor (PBR). The immobilization of S. cerevisiae was performed by entrapment in Ca-alginate for optimization of ethanol production by varying alginic acid concentration, bead size, glucose concentration, temperature and hardening time. Remarkably, extra hardened beads (EHB) immobilized with S. cerevisiae could be used up to repeated 40 fermentation batches. In continuous PBR, maximum 81.82 g L−1 ethanol was obtained with 29.95 g L−1 h−1 productivity with initial glucose concentration of 180 g L−1 in feed at dilution rate of 0.37 h−1. However, maximum ethanol concentration of 40.33 g L−1 (99% yield) with 24.61 g L−1 h−1 productivity was attained at 0.61 h−1 dilution rate in ...

Inositol phosphate accumulation and adenylate cyclase activity were investigated in the cortex of young and aged ethanol-treated rats. Three months of ethanol treatment of young rats decreased maximal stimulation of inositol phosphate accumulation by carbachol by 26%, from 494 ± 76% of basal turnover in control animals to 396 ± 54% in ethanol-treated animals (mean ± SD). In aged rats ethanol-related changes were no longer observed but age-related changes were evident. EC50 was significantly higher than in young animals and maximal stimulation was significantly lower. Basal adenylate cyclase activity in cortical membranes of all groups of animals was not different. Forskolin-stimulated adenylate cyclase activity was not affected by ethanol treatment, but was higher in aged animals. The activity of forskolin-stimulated adenylate cyclase in the presence of carbachol was higher in both young and aged ethanol-treated animals, when compared to young controls. These results suggest that both ethanol ...
BACKGROUND: To assess the prevalence and sociodemographic correlates of suicide involving acute alcohol intoxication among U.S. ethnic minorities. METHODS: Data were derived from the restricted 2003 to 2009 National Violent Death Reporting System. The study focused on the sociodemographic and toxicological information of 59,384 male and female suicide decedents for 16 states of the United States. Acute alcohol intoxication was defined as having a blood alcohol content (BAC) ,/=0.08 g/dl. Overall, 76% of decedents were tested for the presence of alcohol. RESULTS: The proportion of suicide decedents with a positive BAC ranged from 47% among American Indians/Alaska Natives (AIs/ANs) to 23% among Asians/Pacific Islanders (PIs). Average BAC was highest among AIs/ANs. Among those who were tested for BAC, the proportion of decedents legally intoxicated prior to suicide was as follows: Blacks, 15%; AIs/ANs, 36%; Asians/PIs, 13%; and Hispanics, 28%. Bivariate associations showed that most suicide ...
The actions of ethanol on brain ligand-gated ion channels have important roles in the pathophysiology of alcohol-related neurodevelopmental disorders and fetal alcohol syndrome. Studies have shown that N-methyl-d-aspartate (NMDA) receptors are among the ligand-gated ion channels affected by prenatal ethanol exposure. We exposed pregnant dams to an ethanol-containing liquid diet that results in blood ethanol levels near the legal intoxication limit in most states (0.08%). Primary cultures of hippocampal neurons were prepared from the neonatal offspring of these dams, and NMDA receptor function was assessed by patch clamp electrophysiological techniques after 6-7 days in culture in ethanol-free media. Unexpectedly, we did not detect any changes in hippocampal NMDA receptor function at either the whole-cell or single-channel levels. However, we determined that fetal alcohol exposure alters the actions of the neurosteroids pregnenolone sulfate and pregnenolone hemisuccinate, which potentiate NMDA ...
With the discovery of interspecies hydrogen transfer in the late 1960s (Bryant et al. in Arch Microbiol 59:20-31, 1967), it was shown that reducing the partial pressure of hydrogen could cause mixed acid fermenting organisms to produce acetate at the expense of ethanol. Hydrogen and ethanol are both more reduced than glucose. Thus there is a tradeoff between production of these compounds imposed by electron balancing requirements; however, the mechanism is not fully known. Deletion of the hfsA or B subunits resulted in a roughly 1.8-fold increase in ethanol yield. The increase in ethanol production appears to be associated with an increase in alcohol dehydrogenase activity, which appears to be due, at least in part, to increased expression of the adhE gene, and may suggest a regulatory linkage between hfsB and adhE. We studied this system most intensively in the organism Thermoanaerobacterium saccharolyticum; however, deletion of hfsB also increases ethanol production in other thermophilic bacteria
Alcohol tolerance refers to the bodily responses to the functional effects of ethanol in alcoholic beverages. This includes direct tolerance, speed of recovery from insobriety and resistance to the development of alcoholism. Alcohol tolerance is increased by regular drinking. This reduced sensitivity requires that higher quantities of alcohol be consumed in order to achieve the same effects as before tolerance was established. Alcohol tolerance may lead to (or be a sign of) alcohol dependency. Heavy alcohol consumption over a period of years can lead to reverse tolerance. A liver can be damaged by chronic alcohol use, leading to a buildup of fat and scar tissue. The reduced ability of such a liver to metabolize or break down alcohol means that small amounts can lead to a high blood alcohol concentration (BAC) and more rapid intoxication. Direct alcohol tolerance is largely dependent on body size. Large-bodied people will require more alcohol to reach insobriety than lightly built ...

Y1 - 1996/7/1. N2 - To determine actions of acute intoxication on pathophysiologic responses to trauma, anesthetized and ventilated mongrel pigs received a 20% solution of ethanol (EtOH) by an intravenous (IV group; 2 g/kg, n = 8) or an oral (PO group; 3 g/kg, n = 12 x 60 minutes) route of administration, or the lactated Ringers vehicle (LR group; n = 12). After 60 minutes, all were subjected to soft tissue injury and 30 to 35% hemorrhage, 60-minute shock, and then resuscitation, with shed blood plus supplemental LR. After 3 days, host defense was challenged with Escherichia coli lipopolysaccharide (LPS); (1 μg/kg x 30-minutes IV). The supplemental resuscitation was identical (50-53 mL/kg/hours), but posttraumatic acidosis was observed in the IV group and the PO group (base deficit = 4.4 ± 1.3 and 5.5 ± 0.9 ...
Caffeine has been shown to reverse some of the performance-impairing effects of ethanol. However, it is not known whether this antagonistic effect of caffeine is mediated by a reduction in sleepiness. The present study assessed physiological alertness/sleepiness, memory, and psychomotor performance following the administration of placebo, ethanol, and caffeine+ethanol combinations. A total of 13 healthy individuals (21-35 years old) underwent four conditions presented in a Latin Square Design: placebo-placebo, ethanol (0.5 g/kg)-placebo, ethanol (0.5 g/kg)-caffeine 150 mg, and ethanol (0.5 g/kg)-caffeine 300-mg. The Multiple Sleep Latency Test (MSLT), psychomotor performance battery, memory test, and mood/sleepiness questionnaires were administered following each condition. The peak breadth ethanol concentration (BrEC) was 0.043±0.0197% and did not differ among the three caffeine treatments. As expected, ethanol reduced mean latency on the MSLT.

N1 - Copyright: Copyright 2008 Elsevier B.V., All rights reserved.. PY - 2007/2. Y1 - 2007/2. N2 - Chronic heavy alcohol consumption alters cardiac structure and function. Controversies remain as to whether hearts from females respond to the chronic ethanol intake in a manner analogous to males. In particular, sex differences in the myocardial response to chronic alcohol consumption remain unresolved at the molecular level. The purpose of the present set of experiments was to determine whether alterations in cardiac structure and protein metabolism show sexual dimorphism following chronic alcohol consumption for 26 wk. In control animals, hearts from female rats showed lowered heart weights and had thinner ventricular walls compared with males. The smaller heart size was associated with a lower ...

Furthermore, we sought to define the relationship between ethanol in the brain and the accumbal dopamine response after oral self-administration of ethanol. Methods: Two separate groups of male Long-Evans rats were trained to bar press with 10% ethanol or water. Rats were trained to elicit an escalating number of bar presses across daily sessions before gaining access to the drinking solution for 20 min. Microdialysis was performed before (during a waiting period), during, and after ...
Plasma prolactin, luteinizing hormone and estradiol levels were determined in six normal adult females before and during a period of acute alcohol intoxication. Plasma hormone levels found in these studies were compared with values obtained after administration of an isocaloric beverage. Each woman served as her own control for both studies which were carried out on the same day of the menstrual cycle (day 8, 9 or 10) over two consecutive menstrual cycles. Integrated plasma samples were obtained every 20 min for 6 consecutive hr before acute alcohol administration and during the ascending, peak and descending portions of the blood alcohol curve. After acute alcohol administration, all women achieved a moderate degree of intoxication, with mean peak blood alcohol levels of 88 mg/100 ml. No significant differences in levels of luteinizing hormone and estradiol were detected during any phase of the blood alcohol curve when compared to prealcohol administration values. No significant differences ...

Findings show that American Indians are at much greater risk than other ethnic groups.. In 2009, according to the Centers for Disease Control and Prevention, suicide ranked as the 10th leading overall cause of death in the United States. Prior research has also shown that alcohol use disorders confer increased risk for suicide, and are second only to mood disorders as common among individuals who have committed suicide. A study of the prevalence and sociodemographic correlates of suicide involving acute alcohol intoxication among U.S. ethnic minorities has found that American Indians are at much greater risk than other groups.. Results will be published in the May 2013 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.. I do not think that most people in the U.S. are aware that suicide is ranked as the 10th leading cause of death, said Raul Caetano, regional dean (Dallas) and professor of epidemiology at The University of Texas School of Public ...

The effect of long-term ethanol exposure on muscarinic receptors was investigated in human neuroblastoma SH-SY5Y cells. Exposure to 100 mM ethanol for 4 days enhanced both peak and steady-state levels of carbachol-stimulated inositol 1,4,5-bisphosphate increase. An ethanol concentration of 50 mM was sufficient for an enhancement of this event. The carbachol-stimulated decrease in [3H]inositol-labeled [3H]phosphatidylnositol 4,5-bisphosphate and increase [3H]inositol trisphosphate and [3H]inositol bisphosphate were also potentiated in ethanol-treated cells, which demonstrated that the receptor-stimulated activation of phospholipase C is augmented. Experiments with pirenzepine showed that carbachol-stimulated inositol 1,4,5-trisphosphate increase is mediated via M1 receptors both in ethanol-treated and control cells. Ethanol exposure for 2 or 4 days also caused an increase in [3H]N-methylscopolamine and [3H]quinuclidinyl benzilate binding sites and elevation of [3H]pirenzepine binding, which ...
Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person whose mother drank alcohol during pregnancy. Problems may include an abnormal appearance, short height, low body weight, small head size, poor coordination, low intelligence, behavior problems, and problems with hearing or seeing. Those affected are more likely to have trouble in school, legal problems, participate in high-risk behaviors, and have trouble with alcohol or other drugs. The most severe form of the condition is known as fetal alcohol syndrome (FAS). Other types include partial fetal alcohol syndrome (pFAS), alcohol-related neurodevelopmental disorder (ARND) and alcohol-related birth defects (ARBD). Some accept only FAS as a diagnosis, seeing the evidence as inconclusive with respect to other types. Fetal alcohol spectrum disorders are caused by drinking alcohol during pregnancy. Surveys from the United States have found about 10% of pregnant women have drunk alcohol in the last month, and ...
TY - JOUR. T1 - Ethanol differentially regulates proadrenocorticotropin/endorphin production and corticosterone secretion in ls and ss lines of mice. AU - Wand, Gary S.. PY - 1989/1. Y1 - 1989/1. N2 - The stimulatory effects of ethanol administration on the hypothalamic-pituitary-adrenal (HPA) axis were investigated in the long sleep (LS) and short sleep SS) lines of mice, selectively bred for differences in sensitivity to ethanol. To characterize the effects of ethanol exposure on levels of anterior pituitary pro-ACTH/endorphin mRNA, animals were treated with ethanol for either 4 or 7 days. Northern analyses of total RNA extracted from anterior pituitary indicated that ethanol-treated SS mice had 1.5-fold higher pro-ACTH/endorphin mRNA levels on day 4 and 2.5-fold higher mRNA levels on day 7 than SS control mice. Although ethanol-treated LS mice had 4-fold higher pro-ACTH/endorphin mRNA levels on day 4 compared to those in control LS mice, by day 7 pro- ACTH/endorphin mRNA levels in ...
Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, grain alcohol, and EtOH (see Fuel Properties search.) Ethanol has the same chemical formula regardless of whether it is produced from starch- or sugar-based feedstocks, such as corn grain (as it primarily is in the United States), sugar cane (as it primarily is in Brazil), or from cellulosic feedstocks (such as wood chips or crop residues).. Ethanol has a higher octane number than gasoline, providing premium blending properties. Minimum octane number requirements for gasoline prevent engine knocking and ensure drivability. Lower-octane gasoline is blended with 10% ethanol to attain the standard 87 octane.. Ethanol contains less energy per gallon than gasoline, to varying degrees, depending on the volume percentage of ethanol in the blend. Denatured ethanol (98% ethanol) contains about 30% less energy than gasoline per gallon. Ethanols impact on fuel economy is dependent on the ethanol content in the fuel and ...
Alcohol use disorder is a worldwide public health problem and is a disorder with substantial individual variation. There are suggested links between various behavioral traits, comorbid psychiatric diseases and excessive alcohol consumption. Moreover, the endogenous opioid system is involved in alcohol reward and reinforcement, and implicated in the action of alcohol. However, less is known about the complex associations between individual differences in behavior, alcohol consumption, pharmacotherapy response and related neurochemical mechanisms. Experimental animal models are critical for understanding the neurobiological underpinnings of alcohol use disorder.. The overall aims of this thesis were: i) to study the association between behavior and voluntary alcohol intake in outbred rats; ii) to study the association of voluntary alcohol intake, behavior, opioid receptor density and response to naltrexone; and iii) to obtain detailed behavioral characterizations of the animals on the basis of ...

The influence of acute and chronic alcohol exposure on innate immune cells from peripheral blood monocytes to tissue macrophages originating from spleen, lungs, and liver can be diverse. Earlier studies have shown that sterilization of the gut with antibiotics abrogated the in vivo effects of acute alcohol on Kupffer cells, indicating that circulating endotoxin played a key role in the effects of alcohol (32). Furthermore, in vivo acute alcohol exposure of murine Kupffer cells show decreased responsiveness to LPS, and this has been related to decreased IRAK expression, reduced NFκB activity (33), and decreased intracellular Ca2+ concentration (32). Subsequent studies also revealed that acute in vivo ethanol exposure of Kupffer cells increased CD14 expression through a mechanism dependent on AP-1 activation (34). In addition, splenic and alveolar macrophages exposed to a single dose of in vivo alcohol followed by ex vivo stimulation of LPS showed a significant decrease in proinflammatory ...
Youve probably heard of personal breathalysers and wristbands that read your blood alcohol level. But now researchers at the University of California in San Diego have developed a tattoo that analyses your sweat to determine the amount of alcohol in your bloodstream.. The temporary stick-on tattoo releases a drug called pilocarpine onto your skin to induce sweating, and then reads your blood-alcohol levels using a flexible electronic device magnetically attached to the tattoo. The data is beamed via Bluetooth to your smartphone, where you can easily check if youre over the limit. This all happens in less than eight minutes, and if youve had too much to drink, the application can even notify the police or a medical professional.. The developers claim the tattoo is more accurate than a breathalyser, and less invasive than a finger-prick test. They hope the new technology will help individuals to better control their alcohol consumption, as well as empowering bartenders to refuse customers who ...

Betaine, a methyl donor active in methionine metabolism, is effective in preventing and reversing experimental alcohol liver disease. The metabolic and molecular biologic mechanisms involved in this prevention are only partially known. To further investigate how betaine modifies the effects of ethanol on the liver, rats were given an acute ethanol bolus with or without betaine and the results were compared to isocaloric dextrose-fed controls. Livers were subjected to microarray analysis, and functional pathways and individual gene expression changes were analyzed. Experimental groups were compared by Venn diagrams showing that both ethanol and betaine caused a change in the expression of a large number of genes indicating that the changes were global. The bio-informatic analysis showed that all the KEGG functional pathways were affected and mainly down regulated at 3 h post bolus when ethanol plus betaine were compared with ethanol-fed rats. The most profound effect of betaine was on the metabolic
Endogenous levels of salsolinol and dopamine were measured by a gas chromatography/mass spectrometry (GC/MS) - selected ion monitoring technique using deuterated internal standards in Long Evans rats chronically exposed to ethanol for ten months. Chronic ethanol exposure produced significant increases of dopamine and salsolinol concentrations in the medial basal hypothalamus but not striatum. The data suggest that the occurrence of salsolinol in rat brain tissue is a consequence of an in vivo Pictet-Spengler cyclization.
Low ethanol prices relative to the price of gasoline blendstock, and tax credits, have resulted in discretionary blending at wholesale terminals of ethanol into fuel supplies above required levels---a practice known as ethanol splashing in industry parlance. No one knows precisely where or in what volume ethanol is being blended with gasoline and this has important implications for motor fuels markets: Because refiners cannot perfectly predict where ethanol will be blended with finished gasoline by wholesalers, they cannot know when to produce and where to ship a blendstock that when mixed with ethanol at 10 percent would create the most economically efficient finished motor gasoline that meets engine standards and has comparable evaporative emissions as conventional gasoline without ethanol blending. In contrast to previous empirical analyses of biofuels that have relied on highly aggregated data, our analysis is disaggregated to the level of individual wholesale fuel terminals or racks (of which

Ethanol is known as a potent teratogen responsible for the fetal alcohol syndrome characterized by cognitive deficits especially pronounced in juveniles but ameliorating in adults. Since the mechanisms of these deficits and following partial recovery are not fully elucidated, the aim of the present study was to investigate the process of synaptogenesis in the hippocampus over the first two months of life in control and fetal-alcohol rats. Ethanol was delivered to the pregnant dams by intragastric intubation throughout 7-21 gestation days at the daily dose of 6g/kg generating a mean blood alcohol level of 246.6±40.9mg/dl on gestation day 20. The spine densities as well as the expression of pre- and postsynaptic proteins, synaptophysin (SYP) and PSD-95 protein, were evaluated for three distinct hippocampal regions: CA1, CA2+3, and DG and four postnatal days: PD1, PD10, PD30 and PD60, independently. Our results confirmed an intensive synaptogenesis within the brain spurt period (first 10 postnatal days),
NAD or NADP differ with respect to presence or absence of a phosphate group esterified at the 2′ position of the adenosine ribose and are similar at the level of structure. Rosell et al. (21) have shown complete reversal of ADH cofactor specificity in crystallography studies. However, NAD is typically used in oxidative, ATP-generating degradation reactions, and NADP usually acts as a reductant in reductive biosynthetic reactions. An ethanol cycle with two ADH isozymes catalyzing opposite reactions (i.e., ethanol oxidation or ethanol synthesis) has been proposed for Thermoanaerobacter pseudoethanolicus (formerly Clostridium thermohydrosulfuricum) (22) and similarly for the naturally more ethanol-tolerant Zymomonas mobilis (23). We did not test the ethanol cycling hypothesis in this study, but net ethanol oxidation did not appear to be a major detoxification mechanism (SI Appendix, Fig. S6).. The reduction in specific activity with respect to NADH was far greater (∼25-fold less activity) than ...
Rats of the atherosclerosis-prone JCR:LA-corpulent strain were subjected to long-term low (0.5% wt/vol) or high (4% wt/vol) consumption of ethanol from 1 to 12 months of age. The corpulent rats are hyperphagic, obese, and insulin-resistant; exhibit a marked very low density lipoprotein hyperlipidemia; and develop both vascular and myocardial lesions while eating a normal rat chow. The total lipid profile of the rat sera showed only limited changes with ethanol consumption. There were also no significant effects on high density lipoprotein lipids. Ethanol consumption was associated with elevated fasting glucose concentrations in both lean and corpulent rats and a strong decrease in fasting insulin levels and pancreatic B-cell volume density in the hyperinsulinemic corpulent rats. The relative frequency of myocardial nodules of chronic inflammatory cells was increased in the ethanol-consuming rats, both lean and corpulent. In contrast, old organized lesions (scars) were absent in the ...
Fetal alcohol spectrum disorders (FASD) are a group of conditions that can occur in a person whose birth mother consumed alcohol during pregnancy. The effects can include physical problems and/or difficulties with behavior and learning. When clinicians identify FASD early, intervention approaches can minimize the potential impact and lessen or even prevent disabilities. Thus, objective markers for prenatal alcohol exposure are desired.. Using dried blood spots from the umbilical cord and a heel stick of newborns, this study will use Phosphatidylethanol (PEth), a novel biomarker for alcohol exposure, to identify and characterize infants exposure to alcohol before birth. Additionally, the dried blood spots will used to validate the use of screening assays using epigenetic changes as markers for prenatal alcohol exposure. Epigenetic changes are heritable changes in DNA that affect DNA function but do not change DNA sequence. The use of PEth testing will allow for the correlation of prenatal ...
TY - JOUR. T1 - Microbial production of ethanol from acetate by engineered Ralstonia eutropha. AU - Lee, Hye Mi. AU - Jeon, Bo Young. AU - Oh, Min-Kyu. PY - 2016/6/1. Y1 - 2016/6/1. N2 - This study was performed to produce ethanol from acetate using a genetically engineered Ralstonia eutropha. In order to genetically modify R. eutropha H16, phaCAB operon encoding metabolic pathway genes from acetyl-CoA to polyhydroxybutyrate (PHB) was deleted and adhE encoding an alcohol dehydrogenase from Escherichia coli was overexpressed for conversion of acetyl-CoA to ethanol. The resulting strain produced ethanol up to 170 mg/L when cultivated in minimal media supplemented with 5 g/L of acetate as a sole carbon source. Growth and ethanol production were optimized by adjusting nitrogen source (NH4Cl) content and repetitive feeding of acetate into the bacterial culture, by which the ethanol production was reached to approximately 350 mg/L for 84 h.. AB - This study was performed to produce ethanol from ...
Ethanol is a selective CNS depressant at low concentrations, and a general depressant at high concentrations. Initially, ethanol produces exhilaration and loss of inhibition, which progresses to lack of coordination, ataxia, slurred speech, gait disturbances, drowsiness, and, ultimately, stupor, and coma. The intoxicated child may demonstrate a flushed face, dilated pupils, excessive sweating, gastrointestinal distress, hypoventilation, hypothermia, and hypotension. Death from respiratory depression may occur at serum ethanol concentrations >500 mg/dL. Convulsions and death have been reported in children with acute ethanol intoxication owing to alcohol-induced hypoglycemia. Hypoglycemia results from inhibition of hepatic gluconeogenesis and is most common in children younger than 5 years. It does not appear to be directly related to the quantity of ethanol ingested.4 ...
Chronic alcohol intake leads to neuroinflammation and astrocyte dysfunction, proposed to perpetuate alcohol consumption and to promote conditioned relapse-like binge drinking. In the present study, human mesenchymal stem cells (MSCs) were cultured in 3D-conditions to generate MSC-spheroids, which greatly increased MSCs anti-inflammatory ability and reduced cell volume by 90% versus conventionally 2D-cultured MSCs, enabling their intravenous administration and access to the brain. It is shown, in an animal model of chronic ethanol intake and relapse-drinking, that both the intravenous and intra-cerebroventricular administration of a single dose of MSC-spheroids inhibited chronic ethanol intake and relapse-like drinking by 80-90%, displaying significant effects over 3-5 weeks. The MSC-spheroid administration fully normalized alcohol-induced neuroinflammation, as shown by a reduced astrocyte activation, and markedly increased the levels of the astrocyte Na-glutamate (GLT-1) transporter.

Downloadable! The U.S. biofuel industry is striving to produce ethanol from cellulosic feedstock sources in an effort to augment its existing corn grain-based ethanol production infrastructure. Technology to commercially produce cellulosic ethanol is rapidly advancing due in large part to the availability of substancial federal research and development funding. At the moment, several firms have pilot scale cellulosic ethanol production facilities under construction and testing. The transition from pilot scale to full commercialization of cellulosic ethanol will be difficult, due in large part financial constraints being imposed both internally and externally on the biofuels industry. This paper provides an overview of the biofuel industrys current financial setting and describes future challenges it faces in attempting to expand. These challenges are rooted in lack of industry capital, limited availability of performance benchmarks, concerns regarding future prospects of the industry, and general
Recent research findings show that mid-range ethanol blends - fuel mixtures most likely between E20 and E30 - can in some cases provide better fuel economy than regular unleaded gasoline, even in standard, non-flex-fuel vehicles. Previous assumptions held that ethanols lower energy content directly correlates with lower fuel economy for drivers. Those assumptions were found to be incorrect. E20 and E30 ethanol blends outperformed unleaded gasoline in fuel economy tests for certain autos. The tests were conducted using four 2007 model vehicles: a Toyota Camry, a Ford Fusion, and two Chevrolet Impalas, one flex-fuel and one non-flex-fuel. Contrary to Btu-based estimates of fuel economy for ethanol blends, three of the four vehicles tested achieved their highest fuel efficiency not on gasoline, but on an ethanol blend. Mid-level blends of ethanol E20 (20% ethanol, 80% gasoline) and E30 (30% ethanol, 70% gasoline) offered the best fuel economy in these tests. E30 offered better fuel economy than gasoline

Ipecac was used in cough mixtures as an expectorant or an emetic from the 18th until the early 20th century.[citation needed] For instance, Ipecac and opium were used to produce Dover's powder, which was used in syrup form.[citation needed] In 1965, the FDA approved the sale of up to one ounce of syrup of ipecac without a prescription. At the time it was approved, its use was recommended by the AAP, AAPCC, AMA, and the FDA's medical advisory board as a method to induce vomiting "for quick first-aid use in the home, under medical supervision", for use in cases of accidental poisoning.[2][3] Current guidelines from the American Academy of Pediatrics, however, strongly advise against this and in fact recommend the disposal of any syrup of ipecac present in the home.[4] Many toxicological associations have also issued position papers recommending against its use as a first-line treatment for most ingested poisons,[5] because of a lack of evidence that syrup of ipecac actually helps improve the ...
... (trade name Nimelan), also known as N-allylnormorphine dinicotinate, dinicotinoylnalorphine, or niconalorphine, is a semisynthetic, mixed opioid agonist-antagonist which is described as a narcotic antagonist but may produce limited analgesia and sedation at higher doses in opioid naive patients (with limited euphoria and dependence liability).[1][2] It is the 3,6-dinicotinate ester of nalorphine, and is therefore the nalorphine analogue of nicomorphine (which is the 3,6-dinicotinate ester of morphine). As nalorphine dinicotinate is only regulated at the Rx (prescription required) drug, it would be legal to possess with a valid prescription should a patient manage to acquire it.[citation needed] ...

An opioid antagonist, or opioid receptor antagonist, is a receptor antagonist that acts on one or more of the opioid receptors. Naloxone and naltrexone are commonly used opioid antagonist drugs which are competitive antagonists that bind to the opioid receptors with higher affinity than agonists but do not activate the receptors. This effectively blocks the receptor, preventing the body from responding to opioids and endorphins. Some opioid antagonists are not pure antagonists but do produce some weak opioid partial agonist effects, and can produce analgesic effects when administered in high doses to opioid-naive individuals. Examples of such compounds include nalorphine and levallorphan. However, the analgesic effects from these specific drugs are limited and tend to be accompanied by dysphoria, most likely due to additional agonist action at the κ-opioid receptor. As they induce opioid withdrawal effects in people who are taking, or have recently used, opioid full agonists, these drugs are ...
... (INN) (brand names Lethidrone, Nalline), also known as N-allylnormorphine, is a mixed opioid agonist-antagonist with opioid antagonist and analgesic properties.[1] It was introduced in 1954[2] and was used as an antidote to reverse opioid overdose and in a challenge test to determine opioid dependence.[3] It acts at two opioid receptors - the μ-opioid receptor (MOR) where it has antagonistic effects, and at the κ-opioid receptor (KOR) (Ki = 1.6 nM; EC50 = 483 nM; Emax = 95%) where it exerts high-efficacy partial agonist/near-full agonist characteristics.[4] Nalorphine was the second opioid antagonist to be introduced, preceded by nalodeine (N-allylnorcodeine) in 1915 and followed by naloxone in 1960 and naltrexone in 1963.[2] Due to potent activation of the KOR, nalorphine produces side effects such as dysphoria, anxiety, confusion, and hallucinations, and for this reason, is no longer used medically.[1][2][5] Nalorphine has a number of analogues including niconalorphine (the ...
