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.

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.

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.

Nutrients | Free Full-Text | Quercetin Attenuates Chronic Ethanol-Induced Hepatic Mitochondrial Damage through Enhanced...
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.

CYP2E1: Biochemistry, Toxicology, Regulation and Function in Ethanol-Induced Liver Injury | Bentham Science
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 exposure exerts anti-inflammatory effects by inhibiting " by Pranoti Mandrekar, Valentina Jeliazkova et al.
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.

Neuroinflammation and Neurodegeneration in Adult Rat Brain from Binge Ethanol Exposure: Abrogation by Docosahexaenoic Acid
Evidence that brain edema and aquaporin-4 (AQP4) water channels have roles in experimental binge ethanol-induced neurodegeneration has stimulated interest in swelling/edema-linked neuroinflammatory pathways leading to oxidative stress. We report here that neurotoxic binge ethanol exposure produces comparable significant effects in vivo and in vitro on adult rat brain levels of AQP4 as well as neuroinflammation-linked enzymes: key phospholipase A2 (PLA2) family members and poly (ADP-ribose) polymerase-1 (PARP-1). In adult male rats, repetitive ethanol intoxication (3 gavages/d for 4 d, ∼9 g/kg/d, achieving blood ethanol levels ∼375 mg/dl;
Ethanol and galactose metabolism as influenced by 4-methylpyrazole in alcoholics with and without nutritional deficiencies....
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 ...
Hydrogen transfer between ethanol molecules during oxidoreduction in vivo | Biochemical Journal
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 ...

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 ...

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 ...
Ethanol increases receptor-dependent cyclic AMP production in cultured hepatocytes by decreasing Gi-mediated inhibition |...
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 ...
Biomolecules | Free Full-Text | In Vivo Acute on Chronic Ethanol Effects in Liver: A Mouse Model Exhibiting Exacerbated Injury,...
Chronic alcoholics who also binge drink (i.e., acute on chronic) are prone to an exacerbated liver injury but its mechanism is not understood. We therefore investigated the in vivo effects of chronic and binge ethanol ingestion and compared to chronic ethanol followed by three repeat binge ethanol on the liver of male C57/BL6 mice fed ethanol in liquid diet (4%) for four weeks followed by binge ethanol (intragastric administration, 3.5 g/kg body weight, three doses, 12h apart). Chronic followed by binge ethanol exacerbated fat accumulation, necrosis, decrease in hepatic SAM and SAM:SAH ratio, increase in adenosine levels, and elevated CYP2E1 levels. Histone H3 lysine acetylation (H3AcK9), dually modified phosphoacetylated histone H3 (H3AcK9/PS10), and phosphorylated H2AX increased after binge whereas phosphorylation of histone H3 ser 10 (H3S10) and H3 ser 28 (H3S28) increased after chronic ethanol-binge. Histone H3 lysine 4 and 9 dimethylation increased with a marked dimethylation in H3K9 in chronic

Responses of cerebral arterioles during chronic ethanol exposure<...
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 ...
A Spoonful of Sugarcane Ethanol: A Green Tax Medicine for the Cellulosic Ethanol Industry
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 ...
Genetic and Neural Mechanisms Underlying Ethanol-Related Behaviors in Drosophila melanogaster
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
Effect of chronic ethanol exposure on the liver of Clock-mutant mice | Journal of Circadian Rhythms | Full Text
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 ...
Infusing top quality ethanol yeast can increase ethanol yield - Distillersyeast
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 ...
Preventive Nutrition and Food Science | Korea Science
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 ...
Chronic alcohol ingestion exacerbates skeletal muscle myopathy in HIV-1 transgenic rats | AIDS Research and Therapy | Full Text
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
IDEALS @ Illinois: Market entry and exit in the spatial ethanol industry
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 ...
Effect of Ethanol Treatment on Rabbit Corneas | IOVS | ARVO Journals
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 ...
Inhibition of vascular endothelial growth factor signaling facilitates liver repair from acute ethanol-induced injury in...
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 ...
Lignocellulosic ethanol production employing immobilized Saccharomyces cerevisiae in packed bed reactor - Photonell
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 ...

Alcohol Based Hand Sanitizer: Can Frequent Use Cause an Elevated Blood Alcohol Level? - Full Text View - ClinicalTrials.gov
Ethanol continues to be the most frequently abused intoxicant in the United States.4 Drug testing in various work environments has become commonplace during the past two decades and will at times include blood, breath, or urine alcohol testing.5 While valid reasons for false positive drug tests do occur, a plethora of unusual and dubious explanations have been likewise tendered. Medical Review Officers (MRO) involved in evaluating such reports rely on past case reports, knowledge of laboratory analytical techniques, and other scientific evidence to validate or negate claims of drug use in the workplace. ABHS are now found in most hospitals and health-care facilities.1,3 Only one human report of serum ethanol levels following frequent clinical use of the ABHS has been reported.7 This finding of a negative serum ethanol level in this case is likely to be reproducible in all clinical settings as the physician attempted to simulate the most extreme use of the product that would be consistent with ...

Inside the means of anaerobic respiration yeast provides ethanol - Free-label-maker
In the technique of anaerobic respiration yeast yields ethanol. Ethanol fermentation by yeast is a vital course of action during the manufacture of ethanol or booze and while in the means of anaerobic respiration yeast generates ethanol. It is very critical to restrict the presence of oxygen throughout the fermentation process making sure that the yeast can ferment sugars into ethanol or consuming booze because it is also known.. Every single type of ethanol manufacturing including ethanol for human consumption and bio ethanol for powering engines needs to go through the fermentation approach that converts the mashed combination of water coupled with several fruits or grains or greens into ethanol with the desired alcoholic energy. Once the mash is prepared for sugar fermentation then dried yeast powder is additional to the mixture to begin the method of transforming sugars present while in the mixture into ethanol. Even so, during this process, its very crucial to avoid oxygen from remaining ...
Within the technique of anaerobic respiration yeast produces ethanol - Webbceo
Ethanol fermentation by yeast is a vital process during the manufacture of ethanol or alcohol and while in the means of anaerobic respiration yeast generates ethanol. Its very important to restrict the existence of oxygen during the fermentation procedure to ensure the yeast can ferment sugars into ethanol or consuming alcohol due to the fact it is also known.. Each individual sort of ethanol production which include ethanol for human intake and bio ethanol for powering engines needs to pass through the fermentation practice that converts the mashed mixture of water along with various fruits or grains or vegetables into ethanol along with the wished-for alcoholic power. After the mash is ready for sugar fermentation then dried yeast powder is additional towards the combination to start out the method of converting sugars current from the mixture into ethanol. Even so, for the duration of this method, it is rather critical to stop oxygen from remaining present in the combination since it is ...
Kinetic study of batch and fed-batch enzymatic saccharification of pretreated substrate and subsequent fermentation to ethanol ...
The main aim of the present investigation was to achieve high ethanol concentration as the final ethanol concentration in the fermentation broth is critical to make a cost-effective ethanol production process. Since the ethanol concentration is directly proportional to the sugar concentration, hence high concentration sugar syrup is a prerequisite. In the present study, the process modeling consisting of mass balance and kinetic models were used to provide insights into the process performance and to optimize the process for enhanced enzymatic hydrolysis. During the batch saccharification at different consistencies, a regular decrease in the rate constant with increase in the substrate concentration was observed (Figure 1) and the reaction was assumed to be a first order reaction. This decrease in rate may be attributed to the product inhibition, improper heat and mass transfer and the thermal deactivation of enzymes [7, 12]. The difference between the experimental values and those predicted ...

Evaluating the Economics of Ethanol
The ethanol industry has experienced explosive growth in the past several years due to concerns about oil dependence and climate change. However, sentiment has begun to shift against corn ethanol due to increasing food costs, dwindling profit margins and increased government expenditures propping up the industry. Despite the record increase in gasoline prices, ethanol has struggled with its own rising costs of production and market turmoil. This Masters Project assesses the economics of corn-based ethanol production in the United States through the development of three models. The Ethanol Supply Curve Model constructs an ethanol supply curve based on user defined commodity prices. The model compares the marginal cost of ethanol production to the wholesale price of gasoline in order to determine the ability of ethanol to compete with gasoline in the transportation fuel market. The Ethanol Profit Model solves for a facilitys profit margin under user defined commodity conditions. The Ethanol ...
Moderate Alcohol Consumption Is Associated With Left Ventricular Diastolic Dysfunction in Nonalcoholic Hypertensive Patients |...
Ethanol consumption is associated with left ventricular dysfunction in heavy ethanol drinkers. The effect of moderate ethanol intake on left ventricular function in hypertension, however, is unknown. We investigated the relationship between ethanol consumption and cardiac changes in nonalcoholic hypertensive patients. In 335 patients with primary hypertension, we assessed daily ethanol consumption by questionnaires that combined evaluation of recent and lifetime ethanol exposure and examined cardiac structure and function by echocardiography. Patients with abnormal liver tests, previous cardiovascular events, left ventricular ejection fraction ,50%, and creatinine clearance ,30 mL/min 1.72 m2 were excluded. Left ventricular hypertrophy was found in 21% of hypertensive patients and diastolic dysfunction was detected in 50% by tissue-Doppler imaging. Ethanol consumption was comparable in hypertensive patients with and without left ventricular hypertrophy, whereas patients with left ventricular ...

Is acute alcohol ingestion a risk factor for ischemic stroke? Results of a controlled study in middle-aged and elderly stroke...
To assess the role of acute alcohol ingestion as a risk factor for cerebral infarction, we administered a pretested questionnaire to 205 middle-aged and elderly acute ischemic stroke patients and 410 outpatient controls matched by age, sex, race, and method of hospital payment. Paired Mantel-Haenszel analysis revealed that alcohol ingestion within 24 (p = 0.07) and 72 (p = 0.001) hours of stroke onset and medical histories of smoking (p less than 0.0001), hypertension (p less than 0.001), and transient ischemic attacks (p = 0.051) were more common among stroke index cases than controls. Matched multiple logistic analysis revealed that both hypertension (p less than 0.05) and smoking (p less than 0.05) were independently associated with stroke, while alcohol consumption was not. In analyses to assess the possibility of mutual confounding effects of independent variables, the effect of alcohol ingestion was lost when adjusting for smoking. We conclude that acute alcohol ingestion is not an ...
government | e85 Ethanol Alternative Fuels
The ethanol supporters are looking to raise the content of ethanol in every day gasoline from 10 percent ethanol and 90 percent gasoline 20 percent ethanol and 80 percent gasoline. This will double the nations use of ethanol to further reduce Americas oil consumption. E85 (85 percent ethanol 15 percent gasoline) is still seemingly hard to find in many states, e10 has been utilized greatly across the country.. The only threat that can get this shot down is can todays cars use twice the ethanol that is currently available in e10? Some say, older vehicle engines may not be able to run on e20 because it will damage their engines.. The University of Minnesota and Minnesota State University have conducted studies to help ethanol out. They found that e20 will not damage engine parts. The e20 blend is not enough ethanol for engine parts to break down.. Even though there may be skepticism regarding ethanol as the fuel of the future, numerous states in America have laws requiring a certain percent of ...
Cardioprotection by Regular Ethanol Consumption: Potential Mechanisms and Clinical Application | Bentham Science
Keywords: Ethanol, ischemia-reperfusion injury, preconditioning, heart. Abstract: Epidemiological studies demonstrate that excessive drinking is associated with hypertension, cerebral bleeding and loss of cardiac contractility. Conversely, studies have shown that mortality rates for people who regularly drink ethanol in moderation are lower than in abstainers, primarily due to decreased fatal ischemic heart disease. Further, moderate ethanol consumers have lower rates of myocardial infarction compared with abstainers. These beneficial cardiac effects may be due to pleiotropic effects of ethanol on lipids, platelets, and fibrinolytic activity. During the past decade, studies conducted in several animal models have revealed that light to moderate regular ethanol consumption renders hearts more tolerant to myocardial ischemia-reperfusion injury; to a degree similar to cardiac ischemic preconditioning (brief episodes of ischemia dramatically limit infarct size following prolonged ischemia). Recent ...
1 56 P2X7 RECEPTOR ANTAGONISM INHIBITS INFLAMMATORY RESPONSE IN BRAIN INDUCED BY EXPOSURE TO COMBINED ETHANOL AND HIGH-FAT DIET...
2Research Center for Alcoholic Liver Disease and Pancreatitis and Cirrhosis, School of Medicine, University of Southern California, Los Angeles, USA. In the search for novel targets for chronic alcohol-induced inflammatory responses, we recently started exploring the therapeutic potential of ATP-gated purinergic P2X7 receptors (P2X7Rs). Despite the recognized important role in several neurodegenerative pathologies and inflammatory conditions, the role of P2X7Rs in ethanol-induced inflammation and organ damage is still unknown. Using a chronic ethanol exposure model of alcohol liver disease that combines intragastric (iG) ethanol feeding and high fat diet (Hybrid) in C57BL/6J mice, our recent work demonstrated an increased expression of P2X7Rs that paralleled neuroinflammatory changes in several ethanol-sensitive brain regions. These findings served the basis for the hypothesis that there is a functional link between P2X7Rs and chronic ethanol-induced inflammatory response leading to organ ...

Effects of chronic ethanol treatment and aging on brain phosphoinositide turnover and adenylate cyclase activity - UQ eSpace
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 ...
Deletion of the hfsB gene increases ethanol production in Thermoanaerobacterium saccharolyticum and several other thermophilic...
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 - Wikipedia
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 ...

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. The lowest caffeine dose reversed this effect and the

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 ...

American Indians Are At Much Greater Risk Of Suicide Following Acute Alcohol Intoxication - Redorbit
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 disorder - Wikipedia
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 ...

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 ...
Supplier-dependent differences in intermittent voluntary alcohol intake and response to naltrexone in Wistar rats
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 Opposite Effects of Acute and Chronic Alcohol on Lipopolysaccharide-Induced Inflammation Are Linked to IRAK-M in Human...
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 ...
The Temporary Tattoo That Monitors Your Blood Alcohol Level
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 ...

The effects of betaine treatment on rats fed an acute bolus of ethanol at 3 and 12 h post bolus: a microarray analysis | Genes ...
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
Salsolinol and dopamine in rat medial basal hypothalamus after chronic ethanol exposure | Garvan Institute of Medical Research
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.
Biofuels Policy and the Market for Motor Fuels: Empirical Analysis of Ethanol Splashing
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),

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 ...
Development of an Epigenetic Biomarker for Prediction of Fetal Alcohol Spectrum Disorder - Full Text View - ClinicalTrials.gov
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 ...

Alcohols | Strange and Schafermeyer's Pediatric Emergency Medicine, 4e | AccessEmergency Medicine | McGraw-Hill Medical
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 ...
Intravenous administration of anti-inflammatory mesenchymal stem cell spheroids reduces chronic alcohol intake and abolishes...
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.

Financing Growth of Cellulosic Ethanol
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
making biodiesel using Jatropha oil and ethanol - Topic
I made biodiesel using ethanol, palm kernel flakes and potassium hydroxide 85%. I made it twice. The first time I used 95% ethanol, 5% water. The second time I used 99.5% ethanol, 0.5% water. I had better results using the 99.5% ethanol to produce biodiesel. A problem is drying 95% ethanol+ 5% water and doing it inexpensively. There was a little water produced in the 99.5% ethanol when the catalyst was added, but Im not sure how much. If your oil is dry, for one liter of oil use 250 milliliters of ethanol with 5.8 grams 85% potassium hydroxide mixed into the alcohol plus titration number. Heat with constant stirring at 70 to 75 degrees centigrade for one hour. Do not heat with a flame. If possible use a sparkless hot plate. I think starting by making small amounts then working your way up to large quantities is the best way to learn to make the fuel correctly. After heating the ethanol, potassium hydroxide, dry jatropha oil for one hour, let the glycerine settle out long enough, remove the ...
In this paper, we demonstrated that chronic ethanol consumption markedly potentiates T cell-mediated hepatitis induced by injection of Con A in mice. Furthermore, it was determined that ethanol potentiation of T cell-mediated hepatitis is due mainly to enhancing the NF-κB signaling pathway and the subsequent induction of NF-κB-controlled chemokines and adhesion molecule expression in the liver. As shown in Fig. 5, B and C, NF-κB binding, IκB phosphorylation, and IκB degradation after Con A injection were significantly enhanced in ethanol-fed mice compared with pair-fed mice. Consistent with this finding, ICAM-1, MIP-1α, MIP-1β, MIP-2, and MCP-1 expression, which are controlled by NF-κB (11, 18, 37), are significantly prolonged in ethanol-fed mice after Con A injection compared with pair-fed mice. It has been reported (31, 32) that ethanol consumption causes activation of NF-κB and subsequent induction of chemokines and adhesion molecules in rodent livers as well as in monocytes from ...

NASCAR AMERICAN ETHANOL PARTNERSHIP CHANGES TONE REGARDING ETHANOL
NASCAR has successfully driven more than 5.5 million miles on E-15, a 15% blend of corn-based ethanol. The media has taken note. Due in some part to this relationship with NASCAR, reports show that tone of reporting regarding ethanol is now more likely to be positive. In fact, there were zero media stories about American Ethanol in 2013 that were negative in tone to ethanol. The most spoken about trait of ethanol in sports stories is its high-performance trait. The next most popular are environmentally friendly and American-made. And last year, 71 million people were exposed to these American Ethanol messages. Thats not a small accomplishment. Keep an eye on your television this weekend. Austin Dillon will be debuting the American Ethanol No. 3 in the Sprint Cup race at Phoenix.
Genetic engineering of Clostridium thermocellum DSM1313 for enhanced ethanol production | BMC Biotechnology | Full Text
Blending of ethanol with fossil fuel is recommended to address the problem of increasing demand for transportation fuel without environmental pollution. This implementation was planned because ethanol is derived from renewable biological sources, and has promising properties such as anti-knock potential [1, 2] and cleaner combustion [3, 4]. Several countries around the world are adopting this strategy, and are planning to increase the percentage of ethanol blending in a phased manner . In this context, allocation of natural resources for ethanol production in place of food production, and completing interests in ethanol for industrial and potable purposes are the major concerns to be addressed. For example, sugarcane molasses serves as the sole feedstock for bioethanol production in India where the annual production is approximately 2.7 billion litres of which only 30 % is offered for fuel purposes [6, 7]. When considering the supply of feedstock, increasing the production of ethanol from ...
Effects of maternal consumption of ethanol during pregnancy on the developing fetus and offspring: neurobehavioural outcomes,...
Maternal consumption of alcohol during pregnancy is associated with alterations in fetal development that negatively impact the offspring causing neurochemical and neurobehavioural dysfunction termed fetal alcohol spectrum disorders; the most severe outcome is fetal alcohol syndrome. Changes in maternal and fetal hypothalamic-pituitary-adrenal (HPA) axis activation, induction of cytochrome P450 2E1 (CYP2E1) enzyme activity and alterations in micronutrient status, including folate, following chronic ethanol exposure (CEE) are key contributors to the neuroendocrine and neurobehavioural effects observed in offspring. This study tested the following hypotheses: Maternal consumption of ethanol throughout pregnancy can: alter maternal and fetal HPA axis function and induce CYP2E1 enzyme activity in the third-trimester-equivalent; decrease folate status in the maternal-fetal unit, which can be mitigated by folic acid supplementation; and cause neurobehavioural deficits in offspring at low-moderate dose ...
Drosophila tao controls mushroom body development and ethanol-stimulated behavior through par-1. :: MPG.PuRe
Adiponectin, an adipokine predominantly secreted from adipocytes, has been shown to play protective roles against chronic alcohol consumption. While excessive ROS production in macrophages is considered one of the critical events for ethanol-induced damage in various target tissues, the effect of adiponectin on ethanol-induced ROS production is not clearly understood. In the present study, we investigated the effect of globular adiponectin (gAcrp) on ethanol-induced ROS production and the potential mechanisms underlying these effects of gAcrp in macrophages. Here, we demonstrated that gAcrp prevented ethanol-induced ROS production both in RAW 264.7 macrophages and primary murine peritoneal macrophages. Globular adiponectin also inhibited ethanol-induced activation of NADPH oxidase. In addition, gAcrp suppressed ethanol-induced increase in expression of NADPH oxidase subunits, including Nox2 and p22phox, via modulation of NF-κB pathway. Furthermore, pretreatment with Compound C, a selective ...
