Here, L-2-Amino-4-phosphonobutyric acid (L-AP4) is a known potent and selective agonist for the Group III mGlu receptors. However, it does not show any selectivity among the individual group III mGlu subtypes. In order to understand the molecular basis for this group selectivity, we solved the first human mGlu8 amino terminal domain (ATD) crystal structures in complex with L-glu and L-AP4. In comparison with other published L-glu-bound mGlu ATD structures, we have observed L-glu binds in a significantly different manner in mGlu1. Furthermore, these new structures provided evidence that both the electronic and steric nature of the distal phosphate of L-AP4 contribute to its exquisite Group III functional agonist potency and selectivity.

In the current study, we have characterized group I metabotropic glutamate (mGlu) receptor enhancement of 4-aminopyridine (4AP)-evoked [{sup 3}H]glutamate release from rat cerebrocortical synaptosomes. The broad spectrum mGlu receptor agonist (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid ((1S,3R)-ACPD, 10 {mu}M) increased 4AP-evoked [{sup 3}H]glutamate release (143.32{+-}2.73% control) only in the presence of exogenously applied arachidonic acid; an effect reversed by the inclusion of bovine serum albumin (BSA, fatty acid free). In contrast, the selective group I mGlu receptor agonist (S)-3,5-dihydroxyphenylglycine (DHPG) potentiated (EC{sub 50}=1.60{+-}0.25 {mu}M; E{sub max}=147.61{+-}10.96% control) 4AP-evoked [{sup 3}H]glutamate release, in the absence of arachidonic acid. This potentiation could be abolished by either the selective mGlu{sub 1} receptor antagonist (R,S)-1-aminoindan-1,5-dicarboxylic acid (AIDA, 1 mM) or the selective PKC inhibitor (Ro 31-8220, 10 {mu}M) and was BSA-insensitive. The selective mGlu{sub 5} receptor agonist (R,S)-2-chloro-5-hydroxyphenylglycine (CHPG, 300{mu}M) was without effect. DHPG (100 {mu}M) also potentiated both 30 mM and 50 mM K{sup +}-evoked [{sup 3}H]glutamate release (121.60{+-}12.77% and 121.50{+-}4.45% control, respectively). DHPG (100 {mu}M) failed to influence both 4AP-stimulated {sup 45}Ca{sup 2+} influx and 50 mM K{sup +}-induced changes in synaptosomal membrane potential. Possible group I mGlu receptor suppression of tonic adenosine A{sub 1} receptor, group II/III mGlu receptors or GABA{sub B} receptor activity is unlikely since 4AP-evoked [{sup 3}H]glutamate release was insensitive to the selective inhibitory receptor antagonists 8-cyclopentyl-1,3-dimethylxanthine, (R,S)-{alpha}-cyclopropyl-4-phosphonophenylglycine or CGP55845A, respectively. These data suggest an 'mGlu{sub 1} receptor-like' receptor potentiates [{sup 3}H]glutamate release from cerebrocortical synaptosomes in the absence of

Recent Advances in the Medicinal Chemistry of the Metabotropic Glutamate Receptor 1 (mGlu1)

2011-01-01

This Review summarizes the medicinal chemistry found in publications on both orthosteric and allosteric modulators of the metabotropic glutamate receptor 1 (mGlu1) from 2005 to the present. The time period covered by the scope of this current review has been particularly rich in mGlu1-related publications with numbers quadrupling when compared to the preceding five year period of 2000−2005. Publications in the field peaked in 2007 with over 35 articles appearing in the peer reviewed literature in the course of that year. Given that glutamate is one of the primary excitatory neurotransmitters in the mammalian central nervous system (CNS), it is unsurprising that it acts upon several receptors that are considered to be of potential therapeutic interest for many indications. Orthosteric and allosteric modulation of the receptor is possible, with a logical extrapolation to the chemotypes used for each strategy. The last five years of publications have yielded many mGlu1 selective antagonist chemotypyes, most of which have shown efficacy in pain in vivo models. However, the primary impact of these compounds has been to highlight the mechanistic safety risks of mGlu1 antagonism, independent of chemotype. As a review in medicinal chemistry, the primary focus of this paper will be on the design and, to a lesser degree, synthetic strategies for the delivery of subtype selective, CNS penetrant, druglike compounds through a “medchem” program, targeting modulators of the mGlu1 receptor.

The metabotropic Group III agonist, (1S,3R,4S)-1-aminocyclopentane-1,2,4-tricarboxylic acid (ACPT-1), selective for the mGlu(4alpha) receptor, suppresses sound-induced seizures in DBA/2 mice following its intracerebroventricular (i.c.v.) administration (ED(50) 5.6 [2.9-10.7], nmol i.c.v., 15 min, clonic phase) and in genetically epilepsy-prone (GEP) rats following focal administration into the inferior colliculus (ED(50) 0.08 [0.01-0.50], nmol, 60 min, clonic phase). ACPT-1 also protects against clonic seizures induced in DBA/2 mice by the Group I agonist, (RS)-3,5-dihydroxyphenylglycine (3,5-DHPG) (ED(50) 0.60 [0.29-1.2], nmol i.c.v.) and by the Group III antagonist, (RS)-alpha-methylserine-O-phosphate (MSOP) (ED(50) 49.3 [37.9-64.1], nmol i.c.v.). Another Group III agonist, (RS)-4-phosphonophenyl-glycine (PPG), preferentially activating the mGlu(8) receptor, previously shown to protect against sound-induced seizures in DBA/2 mice and GEP rats, also protects against seizures induced in DBA/2 by 3,5-DHPG (ED(50) 3.7 [2.4-5.7], nmol i.c.v.) and by the Group III antagonist, MSOP (ED(50) 40.2 [21.0-77.0], nmol i.c.v.). At very high doses (500 nmol i.c.v. and above), Group III antagonists have pro-convulsant and convulsant activity. The anticonvulsant protection against sound-induced seizures in DBA/2 mice provided by a fully protective dose (20 nmol, i.c.v.) of the mGlu(4) receptor agonist ACPT-1, is partially reversed by the co-administration of the Group III antagonists, MSOP, (RS)-alpha-methyl-4-phosphonophenylglycine (MPPG) or (S)-2-amino-2-methyl-4-phosphonobutanoic acid (MAP4), in the 20-50 nmol dose range. At doses of 50-200 nmol, MPPG and MAP4 cause further reversal of the ACPT-1 anticonvulsant protection, while the MSOP effect on ACPT-1 protection is abolished at higher doses. In contrast, the anticonvulsant protection against sound-induced seizures in DBA/2 mice provided by a fully protective dose (20 nmol, i.c.v.) of the mGlu(8) receptor agonist PPG, is not

We report the anticonvulsant action in DBA/2 mice of two mGlu Group III receptor agonists: (R,S)-4-phosphonophenylglycine, (R,S)-PPG, a compound with moderate mGlu8 selectivity, and of (1S,3R,4S)-1-aminocyclopentane-1,2,4-tricarboxylic acid, ACPT-1, a selective agonist for mGlu4alpha receptors. Both compounds, given intracerebroventricularly at doses which did not show marked anticonvulsant activity, produced a consistent shift to the left of the dose-response curves (i.e. enhanced the anticonvulsant properties) of 1-(4'-aminophenyl)-3,5-dihydro-7,8-dimethoxy-4H-2,3-benzodiazepin-4-one hydrochloride, CFM-2, a noncompetitive AMPA receptor antagonist, and 3-((+/-)-2-carboxypiperazin-4-yl)-1-phosphonic acid, CPPene, a competitive NMDA receptor antagonist, in DBA/2 mice. In addition, (R,S)-PPG and ACPT-1 administered intracerebroventricularly prolonged the time course of the anticonvulsant properties of CFM-2 (33 micromol/kg, i.p.) and CPPene (3.3 micromol/kg, i.p.) administered intraperitoneally. We conclude that modest reduction of synaptic glutamate release by activation of Group III metabotropic receptors potentiates the anticonvulsant effect of AMPA and NMDA receptor blockade.

Negative allosteric modulation of the mGlu7 receptor reduces visceral hypersensitivity in a stress-sensitive rat strain

Directory of Open Access Journals (Sweden)

Rachel D. Moloney

2015-01-01

Full Text Available Glutamate, the main excitatory neurotransmitter in the central nervous system, exerts its effect through ionotropic and metabotropic receptors. Of these, group III mGlu receptors (mGlu 4, 6, 7, 8 are among the least studied due to a lack of pharmacological tools. mGlu7 receptors, the most highly conserved isoform, are abundantly distributed in the brain, especially in regions, such as the amygdala, known to be crucial for the emotional processing of painful stimuli. Visceral hypersensitivity is a poorly understood phenomenon manifesting as an increased sensitivity to visceral stimuli. Glutamate has long been associated with somatic pain processing leading us to postulate that crossover may exist between these two modalities. Moreover, stress has been shown to exacerbate visceral pain. ADX71743 is a novel, centrally penetrant, negative allosteric modulator of mGlu7 receptors. Thus, we used this tool to explore the possible involvement of this receptor in the mediation of visceral pain in a stress-sensitive model of visceral hypersensitivity, namely the Wistar Kyoto (WKY rat. ADX71743 reduced visceral hypersensitivity in the WKY rat as exhibited by increased visceral sensitivity threshold with concomitant reductions in total number of pain behaviours. Moreover, AD71743 increased total distance and distance travelled in the inner zone of the open field. These findings show, for what is to our knowledge, the first time, that mGlu7 receptor signalling plays a role in visceral pain processing. Thus, negative modulation of the mGlu7 receptor may be a plausible target for the amelioration of stress-induced visceral pain where there is a large unmet medical need.

Altered function of the Gq-coupled, Group 1 metabotropic glutamate receptors, specifically mGlu5, is implicated in multiple mouse models of autism and intellectual disability. mGlu5 dysfunction has been most well characterized in the fragile X syndrome mouse model, the Fmr1 knock-out (KO) mouse, where pharmacological and genetic reduction of mGlu5 reverses many phenotypes. mGlu5 is less associated with its scaffolding protein Homer in Fmr1 KO mice, and restoration of mGlu5-Homer interactions by genetic deletion of a short, dominant negative of Homer, H1a, rescues many phenotypes of Fmr1 KO mice. These results suggested that disruption of mGlu5-Homer leads to phenotypes of FXS. To test this idea, we examined mice with a knockin mutation of mGlu5 (F1128R; mGlu5(R/R)) that abrogates binding to Homer. Although FMRP levels were normal, mGlu5(R/R) mice mimicked multiple phenotypes of Fmr1 KO mice, including reduced mGlu5 association with the postsynaptic density, enhanced constitutive mGlu5 signaling to protein synthesis, deficits in agonist-induced translational control, protein synthesis-independent LTD, neocortical hyperexcitability, audiogenic seizures, and altered behaviors, including anxiety and sensorimotor gating. These results reveal new roles for the Homer scaffolds in regulation of mGlu5 function and implicate a specific molecular mechanism in a complex brain disease. Abnormal function of the metabotropic, or Gq-coupled, glutamate receptor 5 (mGlu5) has been implicated in neurodevelopmental disorders, including a genetic cause of intellectual disability and autism called fragile X syndrome. In brains of a mouse model of fragile X, mGlu5 is less associated with its binding partner Homer, a scaffolding protein that regulates mGlu5 localization to synapses and its ability to activate biochemical signaling pathways. Here we show that a mouse expressing a mutant mGlu5 that cannot bind to Homer is sufficient to mimic many of the biochemical, neurophysiological, and

Schizophrenia arises from a complex interplay between genetic and environmental factors. Abnormalities in glutamatergic signaling have been proposed to underlie the emergence of symptoms, in light of various lines of evidence, including the psychotomimetic effects of NMDA receptor antagonists. Metabotropic glutamate receptor 5 (mGlu5) has also been implicated in the disorder, and has been shown to physically interact with NMDA receptors. To clarify the role of mGlu5-dependent behavioral expression by environmental factors, we assessed mGlu5 knockout (KO) mice after exposure to environmental enrichment (EE) or reared under standard conditions. The mGlu5 KO mice showed reduced prepulse inhibition (PPI), long-term memory deficits, and spontaneous locomotor hyperactivity, which were all attenuated by EE. Examining the cellular impact of genetic and environmental manipulation, we show that EE significantly increased pyramidal cell dendritic branching and BDNF protein levels in the hippocampus of wild-type mice; however, mGlu5 KO mice were resistant to these alterations, suggesting that mGlu5 is critical to these responses. A selective effect of EE on the behavioral response to the NMDA receptor antagonist MK-801 in mGlu5 KO mice was seen. MK-801-induced hyperlocomotion was further potentiated in enriched mGlu5 KO mice and treatment with MK-801 reinstated PPI disruption in EE mGlu5 KO mice only, a response that is absent under standard housing conditions. Together, these results demonstrate an important role for mGlu5 in environmental modulation of schizophrenia-related behavioral impairments. Furthermore, this role of the mGlu5 receptor is mediated by interaction with NMDA receptor function, which may inform development of novel therapeutics.

Binge-drinking is the most prevalent form of alcohol abuse and while an early life history of binge-drinking is a significant risk factor for subsequent alcoholism and co-morbid affective disorders, relatively little is known regarding the biobehavioral impact of binge-drinking during the sensitive neurodevelopmental period of adolescence. In adult mice, a month-long history of binge-drinking elicits a hyper-glutamatergic state within the nucleus accumbens (Acb), coinciding with hyper-anxiety. Herein, we employed a murine model of binge-drinking to determine whether or not: (1) withdrawal-induced changes in brain and behavior differ between adult and adolescent bingers; and (2) increased behavioral signs of negative affect and changes in Acb expression of glutamate-related proteins would be apparent in adult mice with less chronic binge-drinking experience (14 days, approximating the duration of mouse adolescence). Adult and adolescent male C57BL/6J mice were subjected to a 14-day binge-drinking protocol (5, 10, 20 and 40% alcohol (v/v) for 2 h/day), while age-matched controls received water. At 24 h withdrawal, half of the animals from each group were assayed for negative affect, while tissue was sampled from the shell (AcbSh) and core (AcbC) subregions of the remaining mice for immunoblotting analyses. Adult bingers exhibited hyper-anxiety when tested for defensive marble burying. Additionally, adult bingers showed increased mGlu1, mGlu5, and GluN2b expression in the AcbSh and PKCε and CAMKII in the AcbC. Compared to adults, adolescent mice exhibited higher alcohol intake and blood alcohol concentrations (BACs); however, adolescent bingers did not show increased anxiety in the marble-burying test. Furthermore, adolescent bingers also failed to exhibit the same alcohol-induced changes in mGlu and kinase protein expression seen in the adult bingers. Irrespective of age, bingers exhibited behavioral hyperactivity in the forced swim test (FST) compared to water

Negative symptoms of schizophrenia are poorly managed using the currently available antipsychotics. Previous studies indicate that agonists of the metabotropic glutamate (mGlu) 2/3 receptors may provide a novel approach for the treatment of schizophrenia. However, the effects of mGlu2/3 receptor agonists or mGlu2 receptor positive allosteric modulators have not yet been clearly elucidated in animal models of the negative symptoms of schizophrenia. Recently, we reported that the forced swimming test in rats treated with subchronic MK-801, an NMDA receptor antagonist, may be regarded as a useful test to evaluate the activities of drugs against the negative symptoms of schizophrenia. We evaluated the effects of LY379268, an mGlu2/3 receptor agonist, and BINA, an mGlu2 receptor positive allosteric modulator, on the hyperlocomotion induced by acute administration of MK-801 (0.15mg/kg, sc) and on the increase in the immobility time in the forced swimming test induced by subchronic treatment with MK-801 (0.5mg/kg, sc, twice a day for 7 days) in rats. Both LY379268 (3mg/kg, sc) and BINA (100mg/kg, ip) attenuated the increase in the immobility time induced by subchronic treatment with MK-801 at the same doses at which they attenuated the MK-801-induced increase in locomotor activity, but had no effect on the immobility time in saline-treated rats. The present results suggest that stimulation of the mGlu2 receptor attenuates the increase in the immobility time in the forced swimming test elicited by subchronic administration of MK-801, and may be potentially useful for treatment of the negative symptoms of schizophrenia.

2013-01-01

Full Text Available Metabotropic glutamate 2/3 (mGlu2/3 receptors have emerged as potential therapeutic targets due to the ability of mGlu2/3 receptor agonists to modulate excitatory transmission at specific synapses. LY354740 and LY379268 are selective and potent mGlu2/3 receptor agonists that show both anxiolytic- and antipsychotic-like effects in animal models. We compared the efficacy of LY354740 and LY379268 in attenuating restraint-stress-induced expression of the immediate early gene c-Fos in the rat prelimbic (PrL and infralimbic (IL cortex. LY354740 (10 and 30 mg/kg, i.p. showed statistically significant and dose-related attenuation of stress-induced increase in c-Fos expression, in the rat cortex. By contrast, LY379268 had no effect on restraint-stress-induced c-Fos upregulation (0.3–10 mg/kg, i.p.. Because both compounds inhibit serotonin 2A receptor (5-HT2AR-induced c-Fos expression, we hypothesize that LY354740 and LY379268 have different in vivo properties and that 5-HT2AR activation and restraint stress induce c-Fos through distinct mechanisms.

Negative allosteric modulators (NAMs) of metabotropic glutamate receptor subtype 5 (mGlu5) have potential applications in the treatment of fragile X syndrome, levodopa-induced dyskinesia in Parkinson disease, Alzheimer disease, addiction, and anxiety; however, clinical and preclinical studies raise concerns that complete blockade of mGlu5 and inverse agonist activity of current mGlu5 NAMs contribute to adverse effects that limit the therapeutic use of these compounds. We report the discovery and characterization of a novel mGlu5 NAM, N,N-diethyl-5-((3-fluorophenyl)ethynyl)picolinamide (VU0477573) that binds to the same allosteric site as the prototypical mGlu5 NAM MPEP but displays weak negative cooperativity. Because of this weak cooperativity, VU0477573 acts as a "partial NAM" so that full occupancy of the MPEP site does not completely inhibit maximal effects of mGlu5 agonists on intracellular calcium mobilization, inositol phosphate (IP) accumulation, or inhibition of synaptic transmission at the hippocampal Schaffer collateral-CA1 synapse. Unlike previous mGlu5 NAMs, VU0477573 displays no inverse agonist activity assessed using measures of effects on basal [(3)H]inositol phosphate (IP) accumulation. VU0477573 acts as a full NAM when measuring effects on mGlu5-mediated extracellular signal-related kinases 1/2 phosphorylation, which may indicate functional bias. VU0477573 exhibits an excellent pharmacokinetic profile and good brain penetration in rodents and provides dose-dependent full mGlu5 occupancy in the central nervous system (CNS) with systemic administration. Interestingly, VU0477573 shows robust efficacy, comparable to the mGlu5 NAM MTEP, in models of anxiolytic activity at doses that provide full CNS occupancy of mGlu5 and demonstrate an excellent CNS occupancy-efficacy relationship.

Metabotropic glutamate (mGlu) receptors mediate in part the CNS effects of glutamate. These receptors interact with a large array of intracellular proteins in which the final role is to regulate receptor function. Here, using co-immunoprecipitation and pull-down experiments we showed a close and specific interaction between mGlu(5) receptor and NECAB2 in both transfected human embryonic kidney cells and rat hippocampus. Interestingly, in pull-down experiments increasing concentrations of calcium drastically reduced the ability of these two proteins to interact, suggesting that NECAB2 binds to mGlu(5) receptor in a calcium-regulated manner. Immunoelectron microscopy detection of NECAB2 and mGlu(5) receptor in the rat hippocampal formation indicated that both proteins are codistributed in the same subcellular compartment of pyramidal cells. In addition, the NECAB2/mGlu(5) receptor interaction regulated mGlu(5b)-mediated activation of both inositol phosphate accumulation and the extracellular signal-regulated kinase/mitogen-activated protein kinase pathway. Overall, these findings indicate that NECAB2 by its physical interaction with mGlu(5b) receptor modulates receptor function.

Traditionally, a reduction in floating behavior or immobility in the Porsolt forced swim test (FST) is employed as a predictor of antidepressant efficacy. However, over the past several years, our studies of alcohol withdrawal-induced negative affect consistently indicate the coincidence of increased anxiety-related behaviors on various behavioral tests with reduced immobility in the FST. Further, this behavioral profile correlates with increased mGlu5 protein expression within limbic brain regions. As the role for mGlu5 in anxiety is well established, we hypothesized that the reduced immobility exhibited by alcohol-withdrawn mice when tested in the FST might reflect anxiety, possibly a hyper-reactivity to the acute swim stressor. Herein, we evaluated whether or not the decreased FST immobility during alcohol withdrawal responds to systemic treatment with a behaviorally-effective dose of the prototypical anxiolytic, buspirone (5 mg/kg). We also determined the functional relevance of the withdrawal-induced increase in mGlu5 expression for FST behavior by comparing the effects of buspirone to a behaviorally effective dose of the mGlu5 negative allosteric modulator MTEP (3 mg/kg). Adult male C57BL/6J mice were subjected to a 14-day, multi-bottle, binge-drinking protocol that elicits hyper-anxiety and increases glutamate-related protein expression during early withdrawal. Control animals received only water. At 24hr withdrawal, animals from each drinking condition were subdivided into groups and treated with an IP injection of buspirone, MTEP, or vehicle, 30min prior to the FST. Drug effects on general locomotor activity were also assessed. As we reported previously, alcohol-withdrawn animals exhibited significantly reduced immobility in the FST compared to water controls. Both buspirone and MTEP significantly increased immobility in alcohol-withdrawn animals, with a modest increase also seen in water controls. No significant group differences were observed for

The effect of alcohol exposure on patients undergoing a laparotomy for trauma is unknown. The purpose of this study was to compare outcomes of morbidity and mortality between alcohol positive and alcohol negative trauma patients who required emergent laparotomies using the National Trauma Data Bank (NTDB). A retrospective database analysis was performed using 28,354 NTDB incident trauma cases, from 2007 through 2012, who had been tested for alcohol and who required abdominal operations (using ICD-9-CM procedure codes) within 24h of presentation. Variables used: age, gender, admission year, alcohol presence, ISS, GCS, injury type & mechanism, discharge status, hospital LOS, ICU stay, ventilator use, and hospital complications. In adjusted analyses, there were no statistically significant differences between the alcohol positive and alcohol negative cohorts when evaluating in-hospital mortality (OR, 0.93; 95% CI: 0.84-1.03), likelihood of earlier hospital discharge (HR, 1.02; 95% CI: 0.99-1.05), and the all-inclusive category of in-hospital complications (OR, 1.04; 95% CI: 0.97-1.12). After adjusting for age, gender, admission year, ISS, GCS, and injury mechanism, there were no major differences between the alcohol positive and alcohol negative cohorts when it came to in-hospital mortality, likelihood of earlier hospital discharge, and most of the in-hospital complications measured among adult trauma patients requiring emergency laparotomies.

Glutamate metabotropic receptors as targets for drug therapy in epilepsy.

Science.gov (United States)

Moldrich, Randal X; Chapman, Astrid G; De Sarro, Giovambattista; Meldrum, Brian S

2003-08-22

Metabotropic glutamate (mGlu) receptors have multiple actions on neuronal excitability through G-protein-linked modifications of enzymes and ion channels. They act presynaptically to modify glutamatergic and gamma-aminobutyric acid (GABA)-ergic transmission and can contribute to long-term changes in synaptic function. The recent identification of subtype-selective agonists and antagonists has permitted evaluation of mGlu receptors as potential targets in the treatment of epilepsy. Agonists acting on group I mGlu receptors (mGlu1 and mGlu5) are convulsant. Antagonists acting on mGlu1 or mGlu5 receptors are anticonvulsant against 3,5-dihydroxyphenylglycine (DHPG)-induced seizures and in mouse models of generalized motor seizures and absence seizures. The competitive, phenylglycine mGlu1/5 receptor antagonists generally require intracerebroventricular administration for potent anticonvulsant efficacy but noncompetitive antagonists, e.g., (3aS,6aS)-6a-naphthalen-2-ylmethyl-5-methyliden-hexahydrocyclopenta[c]furan-1-on (BAY36-7620), 2-methyl-6-(phenylethynyl)pyridine hydrochloride (MPEP), and 2-methyl-6-(2-phenylethenyl)pyridine (SIB-1893) block generalized seizures with systemic administration. Agonists acting on group II mGlu receptors (mGlu2, mGlu3) to reduce glutamate release are anticonvulsant, e.g., 2R,4R-aminopyrrolidine-2,4-dicarboxylate [(2R,4R)-APDC], (+)-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid (LY354740), and (-)-2-oxa-4-aminobicyclo[3.1.0]hexane-4,6-dicarboxylate (LY379268). The classical agonists acting on group III mGlu receptors such as L-(+)-2-amino-4-phosphonobutyric acid, and L-serine-O-phosphate are acutely proconvulsant with some anticonvulsant activity. The more recently identified agonists (R,S)-4-phosphonophenylglycine [(R,S)-PPG] and (S)-3,4-dicarboxyphenylglycine [(S)-3,4-DCPG] and (1S,3R,4S)-1-aminocyclopentane-1,2,4-tricarboxylic acid [ACPT-1] are all anticonvulsant without proconvulsant effects.

5-Hydroxymethylfurfural (HMF) regularly occurs in foods and in alcoholic beverages. However, the risk of HMF associated with alcohol consumption has not been systematically studied, so that this study will provide the first quantitative risk assessment of HMF for consumers of alcoholic beverages. Human dietary intake of HMF via alcoholic beverages in the European Union was estimated based on WHO alcohol consumption data combined with our own survey data (n=944) and literature data (n=147) about the HMF contents of different beverage groups (beer, wine, spirits and unrecorded alcohol). The risk assessment was conducted using the margin of exposure (MOE) approach. For olfactory epithelium metaplasia in female mice, a benchmark dose (BMD) of 127 mg/kg bodyweight (bw)/d and a BMD lower confidence limit (BMDL) of 79 mg/kg bw/d were calculated from National Toxicology Program oral long-term animal experiments. The average human exposure to HMF from alcoholic beverages was estimated at 6.0E-3 mg/kg bw/d, which is approximately 8.5% of the total dietary exposure. In comparison of the human exposure with BMDL, the MOE was 13,167 for average alcohol consumption scenarios, which is a value that would be generally assumed as safe for threshold based compounds. The results show that the risk from HMF to the alcohol-consuming population is rather low and the priority for risk management (e.g. to reduce the contamination) is also low. Further toxicological research about HMF is required to further elucidate its mechanism.

Hallucinogenic drugs, such as lysergic acid diethylamide (LSD), mescaline and psilocybin, alter perception and cognitive processes. All hallucinogenic drugs have in common a high affinity for the serotonin 5-HT2A receptor. Metabotropic glutamate 2/3 (mGlu2/3) receptor ligands show efficacy in modulating the cellular and behavioral responses induced by hallucinogenic drugs. Here, we explored the effect of chronic treatment with the mGlu2/3 receptor antagonist 2S-2-amino-2-(1S,2S-2-carboxycyclopropan-1-yl)-3-(xanth-9-yl)-propionic acid (LY341495) on the hallucinogenic-like effects induced by LSD (0.24 mg/kg). Mice were chronically (21 days) treated with LY341495 (1.5 mg/kg), or vehicle, and experiments were carried out one day after the last injection. Chronic treatment with LY341495 down-regulated [3H]ketanserin binding in somatosensory cortex of wild-type, but not mGlu2 knockout (KO), mice. Head-twitch behavior, and expression of c-fos, egr-1 and egr-2, which are responses induced by hallucinogenic 5-HT2A agonists, were found to be significantly decreased by chronic treatment with LY341495. These findings suggest that repeated blockade of the mGlu2 receptor by LY341495 results in reduced 5-HT2A receptor-dependent hallucinogenic effects of LSD. PMID:23333599

Full Text Available FKBP5 encodes FK506-binding protein 5, a glucocorticoid receptor (GR-binding protein implicated in various psychiatric disorders and alcohol withdrawal severity. The purpose of this study is to characterize alcohol preference and related phenotypes in Fkbp5 knockout (KO mice and to examine the role of FKBP5 in human alcohol consumption. The following experiments were performed to characterize Fkpb5 KO mice. (1 Fkbp5 KO and wild-type (WT EtOH consumption was tested using a two-bottle choice paradigm; (2 The EtOH elimination rate was measured after intraperitoneal (IP injection of 2.0 g/kg EtOH; (3 Blood alcohol concentration (BAC was measured after 3 h limited access of alcohol; (4 Brain region expression of Fkbp5 was identified using LacZ staining; (5 Baseline corticosterone (CORT was assessed. Additionally, two SNPs, rs1360780 (C/T and rs3800373 (T/G, were selected to study the association of FKBP5 with alcohol consumption in humans. Participants were college students (n = 1162 from 21–26 years of age with Chinese, Korean or Caucasian ethnicity. The results, compared to WT mice, for KO mice exhibited an increase in alcohol consumption that was not due to differences in taste sensitivity or alcohol metabolism. Higher BAC was found in KO mice after 3 h of EtOH access. Fkbp5 was highly expressed in brain regions involved in the regulation of the stress response, such as the hippocampus, amygdala, dorsal raphe and locus coeruleus. Both genotypes exhibited similar basal levels of plasma corticosterone (CORT. Finally, single nucleotide polymorphisms (SNPs in FKBP5 were found to be associated with alcohol drinking in humans. These results suggest that the association between FKBP5 and alcohol consumption is conserved in both mice and humans.

Cocaine abuse remains a public health concern for which pharmacotherapies are largely ineffective. Comorbidities between cocaine abuse, depression, and anxiety support the development of novel treatments targeting multiple symptom clusters. Selective negative allosteric modulators (NAMs) targeting the metabotropic glutamate receptor 5 (mGlu5) subtype are currently in clinical trials for the treatment of multiple neuropsychiatric disorders and have shown promise in preclinical models of substance abuse. However, complete blockade or inverse agonist activity by some full mGlu5 NAM chemotypes demonstrated adverse effects, including psychosis in humans and psychotomimetic-like effects in animals, suggesting a narrow therapeutic window. Development of partial mGlu5 NAMs, characterized by their submaximal but saturable levels of blockade, may represent a novel approach to broaden the therapeutic window. To understand potential therapeutic vs adverse effects in preclinical behavioral assays, we examined the partial mGlu5 NAMs, M-5MPEP and Br-5MPEPy, in comparison with the full mGlu5 NAM MTEP across models of addiction and psychotomimetic-like activity. M-5MPEP, Br-5MPEPy, and MTEP dose-dependently decreased cocaine self-administration and attenuated the discriminative stimulus effects of cocaine. M-5MPEP and Br-5MPEPy also demonstrated antidepressant- and anxiolytic-like activity. Dose-dependent effects of partial and full mGlu5 NAMs in these assays corresponded with increasing in vivo mGlu5 occupancy, demonstrating an orderly occupancy-to-efficacy relationship. PCP-induced hyperlocomotion was potentiated by MTEP, but not by M-5MPEP and Br-5MPEPy. Further, MTEP, but not M-5MPEP, potentiated the discriminative-stimulus effects of PCP. The present data suggest that partial mGlu5 NAM activity is sufficient to produce therapeutic effects similar to full mGlu5 NAMs, but with a broader therapeutic index.

Alcohol consumption levels and alcohol use disorder (AUD) symptoms may serve as easily quantifiable markers for AUD relapse after remission and might help prevention workers identify at-risk individuals. We investigated the predictive value of alcohol consumption and AUD symptoms on relapse. Data are from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2). We selected 506 people in ≥12-month DSM-5 AUD remission at baseline and assessed their status at 3-year follow-up. AUD symptoms and drinking patterns were assessed using the Composite International Diagnostic Interview 3.0. Time since remission was assessed retrospectively at baseline and ranged from 1 to 48 years. Predictors for relapse were examined using Cox regression analysis. Cumulative AUD relapse rate was 5.6% at 5 years, 9.1% at 10 years and 12.0% at 20 years. Relapse was predicted by both medium (15-28/22-42 drinks weekly for women/men) and high (≥29/43) past alcohol intake, 6+ lifetime AUD symptoms, 'impaired control over use', and at-risk (≥8/15) current intake. The risk of relapse was especially high when medium or high past intake or 6+ lifetime symptoms coincided with current at-risk drinking. Only a minority of people in DSM-5 AUD remission relapsed, but the risk of relapse increased substantially with the presence of at least one of the risk factors. Moreover, at-risk current drinking coupled with other risk factors substantially increased the likelihood of relapse. Therefore, current drinking may provide an adequate reference point for relapse prevention. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Non-invasive imaging of metabotropic glutamate receptor 5 (mGlu 5 ) in the brain using PET is of interest in e.g., anxiety, depression, and Parkinson's disease. Widespread application of the most widely used mGlu 5 tracer, [ 11 C]ABP688, is limited by the short physical half-life of carbon-11. [ 18 F]PSS232 is a fluorinated analog with promising preclinical properties and high selectivity and specificity for mGlu 5 . In this first-in-man study, we evaluated the brain uptake pattern and kinetics of [ 18 F]PSS232 in healthy volunteers. [ 18 F]PSS232 PET was performed with ten healthy male volunteers aged 20-40 years. Seven of the subjects received a bolus injection and the remainder a bolus/infusion protocol. Cerebral blood flow was determined in seven subjects using [ 15 O]water PET. Arterial blood activity was measured using an online blood counter. Tracer kinetics were evaluated by compartment modeling and parametric maps were generated for both tracers. At 90 min post-injection, 59.2 ± 11.1% of total radioactivity in plasma corresponded to intact tracer. The regional first pass extraction fraction of [ 18 F]PSS232 ranged from 0.41 ± 0.06 to 0.55 ± 0.03 and brain distribution pattern matched that of [ 11 C]ABP688. Uptake kinetics followed a simple two-tissue compartment model. The volume of distribution of total tracer (V T , ml/cm 3 ) ranged from 1.18 ± 0.20 for white matter to 2.91 ± 0.51 for putamen. The respective mean distribution volume ratios (DVR) with cerebellum as the reference tissue were 0.88 ± 0.06 and 2.12 ± 0.10, respectively. The tissue/cerebellum ratios of a bolus/infusion protocol (30/70 dose ratio) were close to the DVR values. Brain uptake of [ 18 F]PSS232 matched the distribution of mGlu 5 and followed a two-tissue compartment model. The well-defined kinetics and the possibility to use reference tissue models, obviating the need for arterial blood sampling, make [ 18 F]PSS232 a promising fluorine-18 labeled

5α-Bile alcohols function as farnesoid X receptor antagonists

The farnesoid X receptor (FXR) is a bile acid/alcohol-activated nuclear receptor that regulates lipid homeostasis. Unlike other steroid receptors, FXR binds bile acids in an orientation that allows the steroid nucleus A to face helix 12 in the receptor, a crucial domain for coactivator-recruitment. Because most naturally occurring bile acids and alcohols contain a cis-oriented A, which is distinct from that of other steroids and cholesterol metabolites, we investigated the role of this 5β-configuration in FXR activation. The results showed that the 5β-(A/B cis) bile alcohols 5β-cyprinol and bufol are potent FXR agonists, whereas their 5α-(A/B trans) counterparts antagonize FXR transactivation and target gene expression. Both isomers bound to FXR, but their ability to induce coactivator-recruitment and thereby induce transactivation differed. These findings suggest a critical role for the A orientation of bile salts in agonist/antagonist function

High comorbidity between personality disorders and alcohol use disorders appears related to individual differences in underlying personality dimensions of behavioral undercontrol and affective dysregulation. However, very little is known about how the Diagnostic and Statistical Manual of Mental Disorders (5th edition; DSM-5) Section III trait model of personality pathology relates to alcohol problems or how the strength of the relationship between personality pathology and alcohol problems changes with age and across gender. The current study examined these questions in a sample of 877 participants using the General Assessment of Personality Disorder to assess general personality dysfunction, the Personality Inventory for DSM-5 to measure specific traits, and the Alcohol Use Disorder Identification Test (AUDIT) to assess problematic alcohol use. Results demonstrated that general personality pathology (Criterion A) was significantly related to problematic alcohol use after controlling for age and gender effects. Furthermore, 2 of the 5 higher-order personality trait domains (Criterion B), Antagonism and Disinhibition, remained significant predictors of problematic alcohol use after accounting for the influence of general personality pathology; however, general personality pathology no longer predicted hazardous alcohol use once Antagonism and Disinhibition were added into the model. Finally, these 2 specific traits interacted with age, such that Antagonism was a stronger predictor of AUDIT scores among older individuals and Disinhibition was a stronger predictor of alcohol problems among younger individuals. Findings support the general validity of this new personality disorder diagnostic system and suggest important age effects in the relationship between traits and problematic alcohol use.

The kinetics of oxidation of various alcohols by purified rat liver alcohol dehydrogenase (ADH) were compared with the kinetics of elimination of the alcohols in rats in order to investigate the roles of ADH and other factors that contribute to the rates of metabolism of alcohols. Primary alcohols (ethanol, 1-propanol, 1-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol) and diols (1,3-propanediol, 1,3-butanediol, 1,4-butanediol, 1,5-pentanediol) were eliminated in rats with zero-order kinetics at doses of 5-20 mmol/kg. Ethanol was eliminated most rapidly, at 7.9 mmol/kgh. Secondary alcohols (2-propanol-d7, 2-propanol, 2-butanol, 3-pentanol, cyclopentanol, cyclohexanol) were eliminated with first order kinetics at doses of 5-10 mmol/kg, and the corresponding ketones were formed and slowly eliminated with zero or first order kinetics. The rates of elimination of various alcohols were inhibited on average 73% (55% for 2-propanol to 90% for ethanol) by 1 mmol/kg of 4-methylpyrazole, a good inhibitor of ADH, indicating a major role for ADH in the metabolism of the alcohols. The Michaelis kinetic constants from in vitro studies (pH 7.3, 37 °C) with isolated rat liver enzyme were used to calculate the expected relative rates of metabolism in rats. The rates of elimination generally increased with increased activity of ADH, but a maximum rate of 6±1 mmol/kg h was observed for the best substrates, suggesting that ADH activity is not solely rate-limiting. Because secondary alcohols only require one NAD(+) for the conversion to ketones whereas primary alcohols require two equivalents of NAD(+) for oxidation to the carboxylic acids, it appears that the rate of oxidation of NADH to NAD(+) is not a major limiting factor for metabolism of these alcohols, but the rate-limiting factors are yet to be identified.

Well-defined unnatural dipeptide-alcohols based on a cis-2,5-disubstitued pyrrolidine backbone were synthesized from commercially available starting materials meso-diethyl-2,5-dibromoadipate, (S)-(-)-1-phenylethylamine, and phenylalaninol. The structures of these unnatural dipeptide-alcohols are supported by HRMS, 1H- and 13C-NMR spectroscopy. These unnatural dipeptide-alcohols can act as building blocks for peptidomimetics.

Human immunodeficiency virus-1 (HIV-1)-encoded transactivator of transcription (Tat) potentiated the depolarization-evoked exocytosis of [(3)H]D-aspartate ([(3)H]D-ASP) from human neocortical terminals. The metabotropic glutamate (mGlu) 1 receptor antagonist 7-(hydroxyimino)cyclopropa[b]chromen-1a-carboxylate ethyl ester (CPCCOEt) prevented this effect, whereas the mGlu5 receptor antagonist 2-methyl-6-(phenylethynyl) pyridine hydrochloride (MPEP) was ineffective. Western blot analysis showed that human neocortex synaptosomes possess mGlu1 and mGlu5 receptors. Tat potentiated the K(+)-evoked release of [(3)H]D-ASP or of endogenous glutamate from mouse neocortical synaptosomes in a CPCCOEt-sensitive and MPEP-insensitive manner. Deletion of mGlu1 receptors (crv4/crv4 mice) or mGlu5 receptors (mGlu5(-/-)mouse) silenced Tat effects. Tat enhanced inositol 1,4,5-trisphosphate production in human and mouse neocortical synaptosomes, consistent with the involvement of group I mGlu receptors. Tat inhibited the K(+)-evoked release of [(3)H]gamma-aminobutyric acid ([(3)H]GABA) from human synaptosomes and that of endogenous GABA or [(3)H]GABA from mouse nerve terminals; the inhibition was insensitive to CPCCOEt or MPEP. Tat-induced effects were retained by Tat(37-72) but not by Tat(48-85). In mouse neocortical slices, Tat facilitated the K(+)- and the veratridine-induced release of [(3)H]D-ASP in a CPCCOEt-sensitive manner and was ineffective in crv4/crv4 mouse slices. These observations are relevant to the comprehension of the pathophysiological effects of Tat in central nervous system and may suggest new potential therapeutic approaches to the cure of HIV-1-associated dementia.

Craving as a DSM-5 Symptom of Alcohol Use Disorder in Non-Treatment Seekers.

Hartwell, Emily E; Ray, Lara A

2018-05-01

DSM-5 has added craving as a new criterion and changed the diagnostic structure of alcohol use disorder (AUD). Though craving has long been a target of intervention, less is known about the impact this addition will have on prevalence and factor structure of AUD, particularly in non-treatment seeker with alcohol problems. Non-treatment seeking individuals reporting alcohol-related problems (N = 296) completed a structured clinical interview and the Penn Alcohol Craving Scale (PACS). PACS scores greater than 20 were considered to meet diagnostic criteria for the alcohol craving symptom. This study examined DSM-IV to DSM-5 diagnostic conversion and conducted an exploratory factor analysis to test the factor structure of the DSM-5 symptoms, including craving. The mean PACS score was 13.1 and alcohol craving was strongly correlated with other measures of alcohol use. Using the proposed cut-off score of PACS > 20, 46 participants (16.2%) met criteria for alcohol craving. Craving loaded moderately (0.47) onto the retained DSM symptoms and produced a unidimensional factor structure. The majority of participants who met for a DSM-IV AUD also met for a DSM-5 AUD (98.8%). Craving prevalence using the PACS was relatively low compared to the remaining 10 DSM-5 symptoms, possibly due to the non-treatment seeking nature of the sample. Conversion of DSM-IV to DSM-5 in this sample led to a small increase in overall AUD prevalence. Craving loaded well onto a single factor structure for AUD.

Re-exploration of the mGlu₁ PAM Ro 07-11401 scaffold: Discovery of analogs with improved CNS penetration despite steep SAR.

This letter describes the re-exploration of the mGlu1 PAM Ro 07-11401 scaffold through a multi-dimensional, iterative parallel synthesis approach. Unlike recent series of mGlu1 PAMs with robust SAR, the SAR around the Ro 07-11401 structure was incredibly steep (only ∼6 of 200 analogs displayed mGlu1 PAM activity), and reminiscent of the CPPHA mGlu5 PAM scaffold. Despite the steep SAR, two new thiazole derivatives were discovered with improved in vitro DMPK profiles and ∼3- to 4-fold improvement in CNS exposure (Kps 1.01-1.19); albeit, with a ∼3-fold diminution in mGlu1 PAM potency, yet comparable efficacy (∼5-fold leftward shift of the glutamate concentration-response curve at 10μM). Thus, this effort has provided additional CNS penetrant mGlu1 PAM tools in a different chemotype than the VU0486321 scaffold. These compounds will permit a better understanding of the pharmacology and therapeutic potential of selective mGlu1 activation, while highlighting the steep SAR challenges that can often be encountered in GPCR allosteric modulator discovery.

Alcohol testing is an expanding area of interest due to the impacts of alcohol abuse that extend well beyond drunk driving. However, existing approaches such as blood and urine assays are hampered in some testing environments by biohazard risks. A noninvasive, in vivo spectroscopic technique offers a promising alternative, as no body fluids are required. The purpose of this work is to report the results of a 36-subject clinical study designed to characterize tissue alcohol measured using near-infrared spectroscopy relative to venous blood, capillary blood, and breath alcohol. Comparison of blood and breath alcohol concentrations demonstrated significant differences in alcohol concentration [root mean square of 9.0 to 13.5 mg/dL] that were attributable to both assay accuracy and precision as well as alcohol pharmacokinetics. A first-order kinetic model was used to estimate the contribution of alcohol pharmacokinetics to the differences in concentration observed between the blood, breath, and tissue assays. All pair-wise combinations of alcohol assays were investigated, and the fraction of the alcohol concentration variance explained by pharmacokinetics ranged from 41.0% to 83.5%. Accounting for pharmacokinetic concentration differences, the accuracy and precision of the spectroscopic tissue assay were found to be comparable to those of the blood and breath assays.

The aim of this paper is to evaluate the protective effect of 5-hydroxymethyl-2-furfural (5-HMF) on acute alcohol-induced liver oxidative injury in mice. 5-HMF, a maillard reaction product, was isolated from the fruits of Schisandra chinensis for animal experiments. Experimental ICR mice were pretreated with different doses of 5-HMF (7.5, 15, and 30 mg/kg) for seven days by gavage feeding. Biochemical markers and enzymatic antioxidants from serum and liver tissue were examined. Our results showed that the activities of ALT (alanine aminotransferase), AST (aspartate transaminase), TC (total cholesterol), TG (triglyceride), L-DLC (low density lipoprotein) in serum and the levels of MDA (malondialdehyde) in liver tissue, decreased significantly (p < 0.05) in the 5-HMF-treated group compared with the alcohol group. On the contrary, enzymatic antioxidants CAT (catalase), GSH-Px (glutathione peroxidase), and GSH SOD (superoxide dismutase) were markedly elevated in liver tissue treated with 5-HMF (p < 0.05). Furthermore, the hepatic levels of pro-inflammatory response marker tumor necrosis factor-alpha (TNF-α) and interleukin-1β (IL-1β) were significantly suppressed (p < 0.05). Histopathological examination revealed that 5-HMF (30 mg/kg) pretreatment noticeably prevented alcohol-induced hepatocyte apoptosis and fatty degeneration. It is suggested that the hepatoprotective effects exhibited by 5-HMF on alcohol-induced liver oxidative injury may be due to its potent antioxidant properties.

We have studied the effects in three rodent models of generalised convulsive or absence epilepsy of two antagonists of group I metabotropic glutamate receptors that are selective for the mGlu1 receptor. LY 367385 ((+)-2-methyl-4-carboxyphenylglycine) and AIDA ((RS)-1-aminoindan-1,5-dicarboxylic acid) have been administered intracerebroventricularly (i.c.v.) to DBA/2 mice and lethargic mice (lh/lh), and focally into the inferior colliculus of genetically epilepsy prone rats (GEPR). In DBA/2 mice both compounds produce a rapid, transient suppression of sound-induced clonic seizures (LY 367385: ED50 = 12 nmol, i.c.v., 5 min; AIDA: ED50 = 79 nmol, i.c.v., 15 min). In lethargic mice both compounds significantly reduce the incidence of spontaneous spike and wave discharges on the electroencephalogram, from 150 min after the administration of AIDA, 500 nmol, i.c.v., and from 30 to >150 min after the administration of LY 367385, 250 nmol, i.c.v. LY 367385, 50 nmol, suppresses spontaneous spike and wave discharges from 30 to 60 min. In genetically epilepsy prone rats both compounds reduce sound-induced clonic seizures. LY 367385, 160 nmol bilaterally, fully suppresses clonic seizures after 2-4 h. AIDA is fully effective 30 min after 100 nmol bilaterally. It is concluded that antagonists of mGlu1 receptors are potential anticonvulsant agents and that activation of mGlu1 receptors probably contributes to a variety of epileptic syndromes.

In this study, we have determined and compared the pharmacological profiles of ibotenic acid and its isothiazole analogue thioibotenic acid at native rat ionotropic glutamate (iGlu) receptors and at recombinant rat metabotropic glutamate (mGlu) receptors expressed in mammalian cell lines....... Thioibotenic acid has a distinct pharmacological profile at group III mGlu receptors compared with the closely structurally related ibotenic acid; the former is a potent (low microm) agonist, whereas the latter is inactive. By comparing the conformational energy profiles of ibotenic and thioibotenic acid...... with the conformations preferred by the ligands upon docking to mGlu1 and models of the other mGlu subtypes, we propose that unlike other subtypes, group III mGlu receptor binding sites require a ligand conformation at an energy level which is prohibitively expensive for ibotenic acid, but not for thioibotenic acid...

Alcohol disorders and re-employment in a 5-year follow-up of long-term unemployed.

Science.gov (United States)

Claussen, B

1999-01-01

To establish whether the high prevalence of alcohol abuse among unemployed people is explained by alcohol abuse causing unemployment, or vice versa. A 5-year postal follow-up survey of a community sample of unemployed from Grenland, southern Norway. Two hundred and twenty-eight unemployed people, registered for more than 12 weeks, aged 16 to 63 years. Response rate 74%. The Alcohol Use Disorder Identification Test (AUDIT) and DSM-III diagnoses of alcohol disorders in medical examinations. At the 5-year follow up, 23% of those still unemployed and 12% of those re-employed scored higher than the AUDIT cut-point of 10. Re-employment reduced the chance of scoring positive on the AUDIT to 34% of the chance for those still unemployed. Significant selection to long-term unemployment according to AUDIT score was not demonstrated. None of the 7% who had a DSM-III diagnosis of an alcohol disorder had a job 5 years later, however, suggesting that alcohol-related selection to unemployment does occur. The high prevalence of harmful drinking among Norwegian unemployed is explained mainly by unemployment causing alcohol abuse rather than vice versa. Reducing unemployment should contribute to reduced alcohol problems in Norway.

Background The effect of alcohol consumption on glycaemic control indicators is not well known. In this study, we studied the effect of alcohol consumption on the plasma glucose and glycaemic control indicators in non-diabetic men. Methods The study enrolled 300 non-diabetic men who received a complete medical checkup (age: 52.8 ± 6.5 years, body mass index: 24.4 ± 2.8 kg/m 2 ). The subjects were divided into four groups by the amount of alcohol consumed, and the plasma glucose, HbA1c, glycated albumin (GA) and 1,5-anhydroglucitol (1,5-AG) concentrations of the groups were compared. Results As the level of alcohol consumption increased, significantly high concentrations of fasting plasma glucose (FPG) were observed, and the oral glucose tolerance test 2-h plasma glucose concentrations tended to rise. While no significant effect of alcohol consumption on HbA1c, 1,5-AG, and the 1,5-AG/FPG ratio was observed, the HbA1c/FPG ratio, GA and the GA/FPG ratio exhibited significantly low values as the level of alcohol consumption increased. In stepwise multivariate regression analysis, alcohol consumption was a significant negative independent variable for HbA1c and GA, but not for 1,5-AG. Conclusions As the level of alcohol consumption increased, the plasma glucose concentrations rose, but the HbA1c and GA concentrations were lower compared with the plasma glucose concentrations. These findings suggest that alcohol consumption may reduce HbA1c and GA concentrations, but not 1,5-AG.

Millions of men around the world suffer from erectile dysfunction, for which phosphodiesterase 5 inhibitors (PDE-5 inhibitors) are currently the first treatment option. Sexual activity and alcohol consumption are closely related, and the simultaneous use of alcohol and PDE-5 inhibitors can happen. Lodenafil carbonate is a new PDE-5 inhibitor, developed by a Brazilian pharmaceutical company. This work aimed at evaluating the cardiovascular safety of lodenafil carbonate, with and without simultaneous alcohol consumption. Fifteen male volunteers received 160 mg lodenafil carbonate (LC), in three different moments. Participants were assigned to three groups, treated with LC in fasting condition, with alcohol or receiving only placebo. The volunteers were continuously monitored during 24 hours for physical impairment, blood pressure, heart rate, QT interval and lodenafil's pharmacokinetic parameters. Lodenafil carbonate alone or with alcohol did not induce clinically relevant modifications in arterial blood pressure or heart rate. A statistically significant decrease in blood pressure was seen four hours after LC and alcohol intake, and an increase in heart rate six hours after intake of lodenafil carbonate alone. The QTc interval was not significantly modified. Lodenafil carbonate bioavailability was increased in 74% when drug intake was associated with alcohol. These results show that the use of lodenafil carbonate did not have clinically relevant effects on blood pressure or heart rate, and was not associated with QT interval prolongation. The association of lodenafil carbonate and alcohol affected its pharmacokinetic properties, increasing the bioavailability of the drug.

Blockade of alcohol's amnestic activity in humans by an alpha5 subtype benzodiazepine receptor inverse agonist.

Alcohol produces many subjective and objective effects in man including pleasure, sedation, anxiolysis, plus impaired eye movements and memory. In human volunteers we have used a newly available GABA-A/benzodiazepine receptor inverse agonist that is selective for the alpha5 subtype (a5IA) to evaluate the role of this subtype in mediating these effects of alcohol on the brain. After pre-treatment with a5IA, we found almost complete blockade of the marked impairment caused by alcohol (mean breath concentration 150mg/100ml) of word list learning and partial but non-significant reversal of subjective sedation without effects on other measures such as intoxication, liking, and slowing of eye movements. This action was not due to alterations in alcohol kinetics and so provides the first proof of concept that selectively decreasing GABA-A receptor function at a specific receptor subtype can offset some actions of alcohol in humans. It also supports growing evidence for a key role of the alpha5 subtype in memory. Inverse agonists at other GABA-A receptor subtypes may prove able to reverse other actions of alcohol, and so offer a new approach to understanding the actions of alcohol in the human brain and in the treatment of alcohol related disorders in humans.

Major depressive disorder (MDD) is a serious public health burden and a leading cause of disability. Its pharmacotherapy is currently limited to modulators of monoamine neurotransmitters and second-generation antipsychotics. Recently, glutamatergic approaches for the treatment of MDD have increasingly received attention, and preclinical research suggests that metabotropic glutamate receptor 5 (mGlu5) inhibitors have antidepressant-like properties. Basimglurant (2-chloro-4-[1-(4-fluoro-phenyl)-2,5-dimethyl-1H-imidazol-4-ylethynyl]-pyridine) is a novel mGlu5 negative allosteric modulator currently in phase 2 clinical development for MDD and fragile X syndrome. Here, the comprehensive preclinical pharmacological profile of basimglurant is presented with a focus on its therapeutic potential for MDD and drug-like properties. Basimglurant is a potent, selective, and safe mGlu5 inhibitor with good oral bioavailability and long half-life supportive of once-daily administration, good brain penetration, and high in vivo potency. It has antidepressant properties that are corroborated by its functional magnetic imaging profile as well as anxiolytic-like and antinociceptive features. In electroencephalography recordings, basimglurant shows wake-promoting effects followed by increased delta power during subsequent non-rapid eye movement sleep. In microdialysis studies, basimglurant had no effect on monoamine transmitter levels in the frontal cortex or nucleus accumbens except for a moderate increase of accumbal dopamine, which is in line with its lack of pharmacological activity on monoamine reuptake transporters. These data taken together, basimglurant has favorable drug-like properties, a differentiated molecular mechanism of action, and antidepressant-like features that suggest the possibility of also addressing important comorbidities of MDD including anxiety and pain as well as daytime sleepiness and apathy or lethargy.

To observe the effects of polydatin on learning and memory and cyclin-dependent kinase 5 (Cdk5) kinase activity in the hippocampus of rats with chronic alcoholism. Forty rats were randomly divided into 4 groups: control group, chronic alcoholism group, low and high polydatin group. The rat chronic alcoholism model was established by ethanol 3.0 g/(kg · d) (intragastric administration). The abstinence scoring was used to evaluate the rats withdrawal symptoms; cognitive function was measured by Morris water maze experiment; Cdk5 protein expression in the hippocampus was detected by immunofluorescence; Cdk5 kinase activity in the hippocampus was detected by liquid scintillation counting method. The abstinence score, escape latency, Cdk5 kinase activity in chronic alcoholism group rats were significantly higher than those of control group (P chronic alcoholism group (P chronic alcoholism group( P chronic alcoholism group were significantly increased compared with control group (P chronic alcoholism group ( P chronic alcoholism damage may interrelate with regulation of Cdk5 kinase activity.

In Australia, most alcohol is sold as packaged liquor from off-premises retailers, a market increasingly dominated by supermarket chains. Competition between retailers may encourage marketing approaches, for example, discounting, that evidence indicates contribute to alcohol-related harms. This research documented the nature and variety of promotional methods used by two major supermarket retailers to promote alcohol products in their supermarket catalogues. Weekly catalogues from the two largest Australian supermarket chains were reviewed for alcohol-related content over 12 months. Alcohol promotions were assessed for promotion type, product type, number of standard drinks, purchase price and price/standard drink. Each store catalogue included, on average, 13 alcohol promotions/week, with price-based promotions most common. Forty-five percent of promotions required the purchase of multiple alcohol items. Wine was the most frequently promoted product (44%), followed by beer (24%) and spirits (18%). Most (99%) wine cask (2-5 L container) promotions required multiple (two to three) casks to be purchased. The average number of standard drinks required to be purchased to participate in catalogue promotions was 31.7 (SD = 24.9; median = 23.1). The median price per standard drink was $1.49 (range $0.19-$9.81). Cask wines had the lowest cost per standard drink across all product types. Supermarket catalogues' emphasis on low prices/high volumes of alcohol reflects that retailers are taking advantage of limited restrictions on off-premise sales and promotion, which allow them to approach market competition in ways that may increase alcohol-related harms in consumers. Regulation of alcohol marketing should address retailer catalogue promotions. [Johnston R, Stafford J, Pierce H, Daube M. Alcohol promotions in Australian supermarket catalogues.

Alcohol is a major cause of chronic pancreatitis. About 5% of alcoholics will ever suffer from pancreatitis, suggesting that additional co-factors are required to trigger an overt disease. Experimental work has implicated lipopolysaccharide, from gut-derived bacteria, as a potential co-factor of alcoholic pancreatitis. This review discusses the effects of alcohol on the gut flora, the gut barrier, the liver-and the pancreas and proposes potential interventional strategies. A better understand...

Most alcoholics experience periods of voluntary alcohol abstinence or imposed alcohol deprivation followed by a return to alcohol drinking. This study examined whether varenicline (VAR) reduces alcohol intake during a return to drinking after periods of alcohol deprivation in rats selectively bred for high alcohol drinking (the alcohol preferring or "P" rats). Alcohol-experienced P rats were given 24-hour access to food and water and scheduled access to alcohol (15% and 30% v/v) for 2 h/d. After 4 weeks, rats were deprived of alcohol for 2 weeks, followed by reaccess to alcohol for 2 weeks, and this pattern was repeated for a total of 3 cycles. Rats were fed either vehicle (VEH) or VAR, in doses of 0.5, 1.0, or 2.0 mg/kg BW, at 1 hour prior to onset of the daily alcohol reaccess period for the first 5 days of each of the 3 alcohol reaccess cycles. Low-dose VAR (0.5 mg/kg BW) reduced alcohol intake during the 5 days of drug treatment in alcohol reaccess cycles 1 and 2. Higher doses of VAR (1.0 mg/kg BW and 2.0 mg/kg BW) reduced alcohol intake during the 5 days of treatment in all 3 alcohol reaccess cycles. The decrease in alcohol intake disappeared with termination of VAR treatment in all alcohol reaccess cycles. The results demonstrate that VAR decreases alcohol intake during multiple cycles of alcohol reaccess following alcohol deprivation in rats and suggests that it may prevent a return to heavy alcohol drinking during a lapse from alcohol abstinence in humans with alcohol use disorder.

1997-10-10

The impact of ethanol, cigarette smoking and heroin on serotonin function was evaluated, first in alcoholics during chronic ethanol intoxication and in opiate addicts after long-term heroin consumption, and secondly in both patient groups after detoxification treatment (i.e. a short-term abstinence of 8 days). Our results showed that the 5-hydroxytryptamine (5-HT) content in platelets was: (1) increased in the subgroup of anti-social alcoholics; (2) transiently and differently altered in alcoholics compared to opiate addicts; and (3) lowered in drinking alcoholics and normal in alcoholics who were drinking as well as smoking (that may occur via MAO-B inhibition by smoke). The findings indicate that alterations of the peripheral and possibly the central serotonin system may occur as predisposing factors for alcoholism in individuals with anti-social traits; they may also have some impact on the progression of alcoholism due to its lowered function during chronic ethanol intoxication that is substantially modified by smoking.

Hagman, Brett T

2016-09-18

It is critical that our alcohol screening instruments maintain their accuracy at detecting DSM-5 Alcohol Use Disorder (AUD) symptomatology. The Alcohol Use Disorders Identification Test (AUDIT) is one of the most widely used alcohol screening instruments, despite no studies evaluating its performance for detecting DSM-5 AUDs. The present study evaluated the performance of the AUDIT in the screening of DSM-5 AUDs in non-treatment seeking college students. Participants (N = 251) were undergraduate students who had at least one binge drinking occasion in the past 90-days. The AUROC value for DSM-5 AUD status in the overall sample was.779 (SE =.029; 95% CIs =.721 to.837). The AUROC values for the reference groups of any DSM-IV AUD and any binge drinker were.798 (SE =.028; 95% CIs =.742 to.853) and.827 (SE =.03; 95% CIs.768 -.886), respectively. A similar pattern of findings emerged between males and females. Gender differences emerged in the identification of AUDIT cut-off scores. A score of ≥ 8 and ≥ 9 had the best balance of sensitivity and specificity for females and males in college, respectively. Findings indicate that the AUDIT has a reasonable degree of diagnostic proficiency in screening for DSM-5 AUDs in college students.

Alcohol is a major contributor to the global burden of disease. In South Africa, alcohol abuse is hypothesized to correlate with women's HIV status, mental health, and partner relationships over time. All pregnant women in 12 urban, low-income, Cape Town neighborhoods were interviewed at baseline, post-birth, and at 6, 12, 36, and 60 months following delivery with retention rates from 82.5 to 94%. Women were assessed for any alcohol use, problematic drinking, depression, intimate partner violence, and HIV status. Prior to pregnancy discovery and 5 years after giving birth, alcohol use was 25.8 and 24.7%, respectively. Most women decreased their alcohol use during pregnancy. Twenty-one percent reported alcohol use on two or more assessments, and only 15% of the mothers drinking alcohol at 5 years were also drinking at baseline. Mothers with depression had a higher likelihood of drinking alcohol compared to mothers who were not depressed only at baseline and 6 months post-birth. Mothers who experienced IPV had more than twice the likelihood of drinking alcohol compared to non-IPV mothers at all assessments. HIV positive mothers were more likely to drink alcohol compared to mothers without HIV prior to pregnancy discovery and at 5 years post-birth. These longitudinal trends in alcohol use among young women in South Africa represent a large economic, social, and health burden and must be addressed in a comprehensive manner.

Continuous alcoholic fermentation

1956-01-01

Results are given of investigations on the continuous production of ethanol on a laboratory and on a semi-commercial scale. The suggested devices are particularly described. Under constant conditions the production cycle required 12 to 17 days, the acidity being 4.0 to 415 ml. 0.1 N NaOH/100 ml and the concentration of fermented wort 10.5 to 11%. The maximum production from 1 h of fermentation space during 24 h was 8.67 l of absolute alcohol when the efflux was divided into several basins; when the efflux of sweet wort was collected into one basin only, the maximum production was 7.20 l of absolute alcohol. The amount of alcohol produced was 62.20 l/100 kg sugar.

5-Aza-2'-deoxycytidine in the medial prefrontal cortex regulates alcohol-related behavior and Ntf3-TrkC expression in rats.

Xiaomeng Qiao

Full Text Available Recent studies have indicated that DNA methylation plays an important role in the development of alcohol abuse. 5-Aza-2'-deoxycytidine (5-Aza-dc, an inhibitor of DNA methyltransferases, was FDA approved for myelodysplastic syndrome treatment. However, it is unclear whether 5-Aza-dc is involved in alcohol abuse. In this study, using a chronic alcohol exposure model in rats, 5-Aza-dc was injected into the medial prefrontal cortex (mPFC. Alcohol-drinking behavior and the anxiety related behavior were evaluated by two-bottle choice and open field test. We found that 5-Aza-dc injection into the mPFC significantly decreased alcohol consumption and alcohol preference in alcohol-exposure rats, corresponding to the reduced blood alcohol levels. Although 5-Aza-dc potentiated the anxiety-like behavior of alcohol-exposure rats, it had no effect on the locomotor activity. Moreover, both of the mRNA and protein levels of DNA Methyltransferase 3A (DNMT3A and DNMT3B in the mPFC were upregulated after 35 days of alcohol exposure and this upregulation could be reversed by 5-Aza-dc treatment. Additionally, 5-Aza-dc reversed the alcohol-induced downregulation of neurotrophin-3 (Ntf3, correspondingly the expression of its receptor-TrkC was reduced. These findings identified a functional role of 5-Aza-dc in alcohol-related behavioral phenotypes and one of the potential target genes, Ntf3. We also provide novel evidence for DNA methyltransferases as potential therapeutic targets in alcohol abuse.

Low-dose prenatal alcohol exposure modulates weight gain and eliminates fractalkine expression in e14.5 mouse embryos

Directory of Open Access Journals (Sweden)

Jordyn Karliner

2017-07-01

Full Text Available Fetal Alcohol Spectrum Disorder (FASD is caused by maternal alcohol consumption during pregnancy and often leads to long-lasting developmental symptoms, including increased microglial migration and increased release of the chemokine, fractalkine, both of which play a role in embryonic brain development. However, the effects of low-dose alcohol exposure on microglia and fractalkine embryonically are not well documented. This study addresses this gap by using the voluntary drinking paradigm, Drinking in the Dark (DiD, to expose mice to acute doses of alcohol from embryonic day 7.5 (E7.5 to E14.5. Maternal mice and embryo analyses revealed increased embryo weights and a trend of increased gestational weight gain in alcohol-exposed mice compared to water-exposed mice. After quantifying soluble fractalkine concentrations through Western Blots, results indicated decreased fractalkine in alcohol-exposed mice compared to water-exposed. Overall, our data suggest that exposure to low doses of alcohol inhibits fractalkine release, which may affect microglial function.

Prior research has revealed a strong relationship between Posttraumatic Stress Disorder (PTSD) and alcohol misuse. However, previous attempts to understand nuanced associations between PTSD symptom clusters and alcohol misuse within military veteran samples have produced mixed results. In an attempt to better understand the associations between PTSD and alcohol misuse, the current study examined the unique relationships between the newly classified Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) PTSD symptom clusters and alcohol misuse in an outpatient sample of military veterans seeking treatment for PTSD and Substance Use Disorders. Veterans (N = 100) were administered a brief battery of self-report questionnaires prior to receiving psychological services to aid in diagnostic assessment and treatment planning. Hierarchical regression analyses revealed that PTSD intrusions (cluster B), negative alterations in cognition and mood (cluster D), and arousal/reactivity (cluster E) symptoms were associated with alcohol misuse. The positive association between alcohol misuse and PTSD symptom severity is consistent with a broader body of literature demonstrating the co-occurrence of these disorders, particularly in military samples. Increased alcohol consumption may interfere with current front-line treatments for PTSD, which encourages patients to experience a full range of emotions. As such, future research should explore the impact of substance use on the effectiveness of trauma focused treatments in the alleviation of DSM-5 PTSD symptoms.

Combustion Characteristics of C5 Alcohols and a Skeletal Mechanism for Homogeneous Charge Compression Ignition Combustion Simulation

KAUST Repository

Park, Sungwoo

2015-10-27

C5 alcohols are considered alternative fuels because they emit less greenhouse gases and fewer harmful pollutants. In this study, the combustion characteristics of 2-methylbutanol (2-methyl-1-butanol) and isopentanol (3-methyl-1-butanol) and their mixtures with primary reference fuels (PRFs) were studied using a detailed chemical kinetic model obtained from merging previously published mechanisms. Ignition delay times of the C5 alcohol/air mixtures were compared to PRFs at 20 and 40 atm. Reaction path analyses were conducted at intermediate and high temperatures to identify the most influential reactions controlling ignition of C5 alcohols. The direct relation graph with expert knowledge methodology was used to eliminate unimportant species and reactions in the detailed mechanism, and the resulting skeletal mechanism was tested at various homogeneous charge compression ignition (HCCI) engine combustion conditions. These simulations were used to investigate the heat release characteristics of the methyl-substituted C5 alcohols, and the results show relatively strong reactions at intermediate temperatures prior to hot ignition. C5 alcohol blending in PRF75 in HCCI combustion leads to a significant decrease of low-temperature heat release (LTHR) and a delay of the main combustion. The heat release features demonstrated by C5 alcohols can be used to improve the design and operation of advanced engine technologies.

Physicochemical Properties of α-Form Hydrated Crystalline Phase of 3-(10-Carboxydecyl)-1,1,1,3,5,5,5-heptamethyl Trisiloxane/Higher alcohol/Polyoxyethylene (5 mol) Glyceryl monostearate/Water System.

The α-form hydrated crystalline phase (often called as an α-gel) is one of the hydrated crystalline phases which can be exhibited by surfactants and lipids. In this study, a novel system of an α-form hydrated crystal was developed, composed of 3-(10-carboxydecyl)-1,1,1,3,5,5,5-heptamethyl trisiloxane (CDTS), polyoxyethylene (5 mol) glyceryl monostearate (GMS-5), higher alcohol. This is the first report to indicate that a silicone surfactant can form an α-form hydrated crystal. The physicochemical properties of this system were characterized by small and wide angle X-ray scattering (SWAXS), differential scanning calorimetry (DSC), and diffusion-ordered NMR spectroscopy (DOSY) experiments. SWAXS and DSC measurements revealed that a plurality of crystalline phases coexist in the CDTS/higher alcohol/water ternary system. By adding GMS-5 to the ternary system, however, a wide region of a single α-form hydrated crystalline phase was obtained. The self-diffusion coefficients (D sel ) from the NMR measurements suggested that all of the CDTS, GMS-5, and higher alcohol molecules were incorporated into the same α-form hydrated crystals.

Alcohol alters hepatic FoxO1, p53, and mitochondrial SIRT5 deacetylation function

2008-01-01

Chronic alcohol consumption affects the gene expression of a NAD-dependent deacetylase Sirtuis 1 (SIRT1) and the peroxisome proliferator-activated receptor-γ coactivator1α (PGC-1α). Our aim was to verify that it also alters the forkhead (FoxO1) and p53 transcription factor proteins, critical in the hepatic response to oxidative stress and regulated by SIRT1 through its deacetylating capacity. Accordingly, rats were pair-fed the Lieber-DeCarli alcohol-containing liquid diets for 28 days. Alcohol increased hepatic mRNA expression of FoxO1 (p = 0.003) and p53 (p = 0.001) while corresponding protein levels remained unchanged. However phospho-FoxO1 and phospho-Akt (protein kinase) were both decreased by alcohol consumption (p = 0.04 and p = 0.02, respectively) while hepatic p53 was found hyperacetylated (p = 0.017). Furthermore, mitochondrial SIRT5 was reduced (p = 0.0025), and PGC-1α hyperacetylated (p = 0.027), establishing their role in protein modification. Thus, alcohol consumption disrupts nuclear-mitochondrial interactions by post-translation protein modifications, which contribute to alteration of mitochondrial biogenesis through the newly discovered reduction of SIRT5

To investigate whether the effects of family conflict on adolescent drinking differed as a function of 5-hydroxy tryptamine transporter-linked polymorphic region (5-HTTLPR) genotype cross-sectionally and prospectively in two independent samples of adolescents. Path analysis and multi-group analysis of two prospective datasets were conducted. United States and United Kingdom. Sample 1 was 175 adolescents in the United States (mean age = 15 at times 1 and 2 with a 6-month interval); Sample 2 was 4916 adolescents in the United Kingdon (mean age = 12 at time 1 and 15 at time 2). In both samples, demographics, tri-allelic 5-HTTLPR genotype and perceived family conflict were assessed at time 1. Alcohol use (frequency of drinking) and alcohol misuse (frequency of intoxication, frequency of drinking three or more drinks, maximum number of drinks) were assessed at times 1 and 2. A significant gene-environment interaction on alcohol misuse at time 1 was found in both sample 1 (β = 0.57, P = 0.001) and sample 2 (β = 0.19, P = 0.01), indicating that the 5-HTTLPR low-activity allele carriers exposed to higher levels of family conflict were more likely to engage in alcohol misuse than non-carriers. A significant gene-environment interaction effect on change in alcohol misuse over time was found only in sample 1 (β = 0.48, P = 0.04) but not in sample 2. Compared with non-carriers, adolescents carrying the 5-HTTLPR low-activity allele are more susceptible to the effects of family conflict on alcohol misuse. © 2014 Society for the Study of Addiction.

Thermochemical study of deuterium exchange reactions in water-alcohol and alcohol-alcohol systems

Molar excess enthalpies of water-alcohol systems have been analyzed to give equilibrium constants and enthalpies of the reactions 2ROH + D 2 O = 2ROD + H 2 O (R = CH 3 , C 2 H 5 , n-C 3 H 7 ). The equilibrium constants are significantly greater than the ''random'' value. Molar excess enthalpies of alcohol-alcohol systems have been analyzed to give enthalpies of reactions ROH + R'OD = ROD + R'OH. The enthalpies of water-alcohol and alcohol-alcohol exchange reactions form a self-consistent set and are in good agreement with values from earlier studies. Molar excess enthalpies at 298.15 K are reported for n-C 3 H 7 OH and n-C 3 H 7 OD with H 2 O, D 2 O, CH 3 OH, CH 3 OD, C 2 H 5 OH, and C 2 H 5 OD

Impaired response inhibition in the rat 5 choice continuous performance task during protracted abstinence from chronic alcohol consumption.

Directory of Open Access Journals (Sweden)

Cristina Irimia

Full Text Available Impaired cognitive processing is a hallmark of addiction. In particular, deficits in inhibitory control can propel continued drug use despite adverse consequences. Clinical evidence shows that detoxified alcoholics exhibit poor inhibitory control in the Continuous Performance Task (CPT and related tests of motor impulsivity. Animal models may provide important insight into the neural mechanisms underlying this consequence of chronic alcohol exposure though pre-clinical investigations of behavioral inhibition during alcohol abstinence are sparse. The present study employed the rat 5 Choice-Continuous Performance Task (5C-CPT, a novel pre-clinical variant of the CPT, to evaluate attentional capacity and impulse control over the course of protracted abstinence from chronic intermittent alcohol consumption. In tests conducted with familiar 5C-CPT conditions EtOH-exposed rats exhibited impaired attentional capacity during the first hours of abstinence and impaired behavioral restraint (increased false alarms during the first 5d of abstinence that dissipated thereafter. Subsequent tests employing visual distractors that increase the cognitive load of the task revealed significant increases in impulsive action (premature responses at 3 and 5 weeks of abstinence, and the emergence of impaired behavioral restraint (increased false alarms at 7 weeks of abstinence. Collectively, these findings demonstrate the emergence of increased impulsive action in alcohol-dependent rats during protracted alcohol abstinence and suggest the 5C-CPT with visual distractors may provide a viable behavioral platform for characterizing the neurobiological substrates underlying impaired behavioral inhibition resulting from chronic intermittent alcohol exposure.

Alcoholic fatty liver is enhanced in CYP2A5 knockout mice: The role of the PPARα-FGF21 axis

International Nuclear Information System (INIS)

Chen, Xue; Ward, Stephen C.; Cederbaum, Arthur I.; Xiong, Huabao; Lu, Yongke

2017-01-01

Background & aims: Cytochrome P450 2A5 (CYP2A5) is induced by ethanol, and the ethanol induction of CYP2A5 is regulated by nuclear factor-erythroid 2-related factor 2 (NRF2). Cyp2a5 knockout (Cyp2a5 −/− ) mice develop more severe alcoholic fatty liver than Cyp2a5 +/+ mice. Fibroblast growth factor 21 (FGF21), a PPARα-regulated liver hormone, is involved in hepatic lipid metabolism. Alcoholic and non-alcoholic fatty liver are enhanced in Pparα knockout (Pparα −/− ) mice. This study investigates the relationship between the PPARα-FGF21 axis and the enhanced alcoholic fatty liver in Cyp2a5 −/− mice. Methods: Mice were fed the Lieber-Decarli ethanol diet to induce alcoholic fatty liver. Results: More severe alcoholic fatty liver disease was developed in Cyp2a5 −/− mice than in Cyp2a5 +/+ mice. Basal FGF21 levels were higher in Cyp2a5 −/− mice than in Cyp2a5 +/+ mice, but ethanol did not further increase the elevated FGF21 levels in Cyp2a5 −/− mice while FGF21 was induced by ethanol in Cyp2a5 +/+ mice. Basal levels of serum FGF21 were lower in Pparα −/− mice than in Pparα +/+ mice; ethanol induced FGF21 in Pparα +/+ mice but not in Pparα −/− mice, whereas ethanol induced hypertriglyceridemia in Pparα −/− mice but not in Pparα +/+ mice. Administration of recombinant FGF21 normalized serum FGF21 and triglyceride in Pparα −/− mice. Alcoholic fatty liver was enhanced in liver-specific Fgf21 knockout mice. Pparα and Cyp2a5 double knockout (Pparα −/− /Cyp2a5 −/− ) mice developed more severe alcoholic fatty liver than Pparα +/+ /Cyp2a5 −/− mice. Conclusions: These results suggest that CYP2A5 protects against the development of alcoholic fatty liver disease, and the PPARα-FGF21 axis contributes to the protective effects of CYP2A5 on alcoholic fatty liver disease.

Given the association between alcohol consumption and negative health consequences, there is a need for individuals to be aware of their consumption of ethanol, which requires knowledge of serving sizes and alcoholic strength. This study is one of the first to systematically investigate the ability to discriminate alcoholic strength by taste. Nine discrimination tests (total n = 413) according to International Standardization Organization (ISO) 4120 sensory analysis methodology "triangle test" were performed. A perceptible difference was found for vodka in orange juice (0.0 vs. 0.5% vol; 0 vs. 1% vol), pilsner and wheat beer (0.5 vs. 5% vol), and vodka in orange juice (5 vs. 10% vol, 20 vs. 30% vol, and 30 vs. 40% vol). The percentage of the population perceiving a difference between the beverages varied between 36 and 73%. Alcoholic strength (higher vs. lower) was correctly assigned in only 4 of the 7 trials at a significant level, with 30 to 66% of the trial groups assigning the correct strength. For the trials that included beverages above 40% vol (vodka unmixed, 40 vs. 50% vol and vodka in orange juice, 40 vs. 50% vol), testers could neither perceive a difference between the samples nor assign correct alcoholic strength. Discrimination of alcoholic strength by taste was possible to a limited degree in a window of intermediate alcoholic strengths, but not at higher concentrations. This result is especially relevant for drinkers of unlabeled, over-proof unrecorded alcoholic beverages who would potentially ingest more alcohol than if they were to ingest commercial alcohol. Our study provides strong evidence for the strict implementation and enforcement of labeling requirements for all alcoholic beverages to allow informed decision making by consumers.

Caetano, Raul; Gruenewald, Paul; Vaeth, Patrice A C; Canino, Glorisa

2018-02-01

Our aim was to examine lifetime criteria profiles and correlates of severity (mild, moderate, severe) of DSM-5 alcohol use disorders (AUD) in Puerto Rico. Data are from a household random sample of individuals 18 to 64 years of age in San Juan, Puerto Rico. The survey response rate was 83%. DSM-5 AUD was identified with the Spanish version of the World Health Organization's Composite International Diagnostic Interview. The analyses also identify correlates of each severity level using an ordered logistic regression model. The prevalence of lifetime DSM-5 AUD among men and women was 38 and 16%, respectively. Mild lifetime DSM-5 AUD was the most prevalent severity level among both men (18%) and women (9%). The most common criteria, independent of gender and severity level, were drinking larger quantities and for longer than planned (men range: 80 to 97%; women range: 78 to 91%) and hazardous use (men range: 56 to 91%; women range: 42 to 74%). Results from ordered logistic regression showed that the adjusted odds ratio for weekly drinking frequency, greater volume of alcohol consumed per drinking occasion, positive attitudes about drinking, drinking norms, and male gender invariantly increased risks across all DSM-5 AUD severity levels (mild, moderate, severe). Greater negative attitudes about drinking, low family cohesion, and Protestant religion were related to greater risks at higher AUD severity levels. AUD prevalence is high in San Juan, Puerto Rico. Prevalence rates for some criteria are equally high across severity levels and poorly differentiate between mild, moderate, or severe DSM-5 AUD. The sociodemographic and alcohol-related risks vary across DSM-5 severity levels. Copyright © 2018 by the Research Society on Alcoholism.

5-HT1A receptor-dependent modulation of emotional and neurogenic deficits elicited by prolonged consumption of alcohol.

Science.gov (United States)

Belmer, Arnauld; Patkar, Omkar L; Lanoue, Vanessa; Bartlett, Selena E

2018-02-01

Repeated episodes of binge-like alcohol consumption produce anxiety, depression and various deleterious effects including alterations in neurogenesis. While the involvement of the serotonin receptor 1 A (5-HT 1A ) in the regulation of anxiety-like behavior and neurogenesis is well documented, its contribution to alcohol withdrawal-induced anxiety and alcohol-induced deficits in neurogenesis is less documented. Using the Drinking-In-the-Dark (DID) paradigm to model chronic long-term (12 weeks) binge-like voluntary alcohol consumption in mice, we show that the selective partial activation of 5-HT 1A receptors by tandospirone (3 mg/kg) prevents alcohol withdrawal-induced anxiety in a battery of behavioral tests (marble burying, elevated-plus-maze, open-field), which is accompanied by a robust decrease in binge-like ethanol intake (1 and 3 mg/kg). Furthermore, using triple immunolabelling of proliferation and neuronal differentiation markers, we show that long-term DID elicits profound deficits in neurogenesis and neuronal fate specification in the dorsal hippocampus that are entirely reversed by a 2-week chronic treatment with the 5-HT 1A partial agonist tandospirone (3 mg/kg/day). Together, our results confirm previous observations that 5-HT 1A receptors play a pivotal role in alcohol drinking behavior and the associated emotional and neurogenic impairments, and suggest that 5-HT 1A partial agonists represent a promising treatment strategy for alcohol abuse.

Liang, C; Chen, J; Gu, W; Wang, H; Xue, Z

2011-10-01

The present study was designed to investigate the possible effect of chronic alcohol intake on propofol and remifentanil requirements, which was determined by quantifying the 50% (EC(50) ) and 95% (EC(95) ) effective effect-site concentrations for propofol and remifentanil at loss of consciousness (LOC) and after a painful stimulus. Thirty male patients (alcoholic group; n = 30) with chronic alcoholism and 30 patients (control group; n = 30) with a history of small alcohol intake were anaesthetized with propofol and remifentanil by target-controlled infusion. The predicted drug concentrations and Bispectral Index (BIS) values were recorded at LOC and after no response to painful stimuli. The EC(50) and EC(95) of propofol at LOC in alcoholic group were 3.15 [95% confidence interval (CI), 2.77-3.37] and 4.05 (95% CI, 3.18-5.26) μg/ml, respectively, and those of the control group were 2.21 (95% CI, 1.92-2.86) and 3.04 (95% CI, 2.45-4.64) μg/ml, respectively. The EC(50) and EC(95) of remifentanil measured after no response to painful stimuli in the alcoholic group were 3.02 (95% CI, 2.70-3.38) and 4.98 (95% CI, 4.56-5.89) ng/ml, respectively, and those of the control group were 2.95 (95% CI, 2.68-3.33) and 4.86 (95% CI, 4.55-5.92) ng/ml, respectively. The EC(50) and EC(95) values of propofol at LOC in the control group were significantly lower than that of the alcoholic group. These findings suggest that the induction dose requirements of propofol are increased in alcoholic patients anaesthetized with propofol and remifentanil administered by target controlled infusion. 2011 The Authors Acta Anaesthesiologica Scandinavica, 2011 The Acta Anaesthesiologica Scandinavica Foundation.

Contingency management (CM) has not been thoroughly evaluated as a treatment for alcohol abuse or dependence, in part because verification of alcohol use reduction requires frequent in-person breath tests. Transdermal alcohol sensors detect alcohol regularly throughout the day, providing remote monitoring and allowing for rapid reinforcement of reductions in use. The purpose of this study was to evaluate the efficacy of CM for reduction in alcohol use, using a transdermal alcohol sensor to provide a continuous measure of alcohol use. Participants were 13 heavy drinking adults who wore the Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet for three weeks and provided reports of alcohol and drug use using daily web-based surveys. In Week 1, participants were asked to drink as usual; in Weeks 2 and 3, they were reinforced on an escalating schedule with values ranging from $5 to $17 per day on days when alcohol use was not reported or detected by the SCRAM. Self-reports of percent days abstinent and drinks per week, and transdermal measures of average and peak transdermal alcohol concentration and area under the curve declined significantly in Weeks 2-3. A nonsignificant but large effect size for reduction in days of tobacco use also was found. An adjustment to the SCRAM criteria for detecting alcohol use provided an accurate but less conservative method for use with non-mandated clients. Results support the efficacy of CM for alcohol use reductions and the feasibility of using transdermal monitoring of alcohol use for clinical purposes. Copyright © 2011 Elsevier Ireland Ltd.

Alcohol Use Disorders: Implications for the Clinical Toxicologist

Directory of Open Access Journals (Sweden)

Michael McDonough

2015-03-01

Full Text Available Alcohol use disorders (AUDs are a health problem of high prevalence in most communities and such problems account for 5% of the total burden of disease worldwide. Clinical toxicologists are commonly required to treat patients having AUDs and associated drug/alcohol-related harm. There have been recent changes to some of the diagnostic criteria (notably in DSM V relevant to AUDs, with older terms “alcohol abuse” and “alcohol dependence” no longer being classified. AUDs may sometimes not be clearly recognizable and use of evidence-based screening interventions can help identify such conditions and lead to effective brief interventions (e.g. SBIRT programs in emergency departments. AUDs are viewed as chronic disorders of alcohol consumption occurring across a spectrum of severity. While most AUDs are mild to moderate in severity and usually self-limiting conditions, more severe presentations are more commonly encountered by physicians in emergency settings. Hence, clinical toxicologists are more likely to see patients within the more severe form of disorder, at end of the spectrum of AUDs. Among this group of patients, multi-morbidity and particularly high mortality risk exists, and thus they usually require management collaboration with specialist services. Patients with AUDs are most likely to be recognized by a clinical toxicologist in the following scenarios: following acute heavy alcohol ingestion and subsequently developing acute alcohol intoxication (ethanol toxidrome, following accidental or intentional drug overdosage where alcohol has also been consumed, following acute alcohol consumption that has been associated with behavioral risk-taking and/or self-harming (e.g. poisoning, envenomation, etc., when alcohol withdrawal reactions are severe requiring hospitalization and possibly following an adverse drug reaction.

AlcoholEdu® for College and other computer-based education programs have been developed to reduce alcohol use and related problems among students. This study investigated whether the failure of incoming first-year students to complete AlcoholEdu predicts future high-risk drinking that requires medical attention. A review of clinical records kept by a single university's health service identified 684 undergraduates (classes of 2007-2011) who had presented for an alcohol event (September 2003 through June 2008). We used survival analysis to determine whether students who partially completed the course or failed to take it were disproportionately represented among student patients who presented with elevated blood alcohol concentration (BAC). Students who failed to take the online course were 4.64 times more likely than those who completed it to experience an alcohol event (p students who had partially completed the course were 1.52 times more likely (p alcohol education and gender were not significantly related to students' measured BAC level. Students who had completed AlcoholEdu were less likely to present for an alcohol event than were students who partially completed or failed to take the course. Campus administrators should consider whether students who fail to complete an online alcohol course should be flagged for more focused interventions (e.g., brief motivational interview, mandatory education classes). This is the first study to show a relationship between first-year college students' non-completion of an online alcohol course and subsequent high-risk drinking that requires medical attention.

2014-07-01

The recently published Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) includes several major revisions to substance use diagnoses. Studies have evaluated the impact of these changes among adult samples but research with adolescent samples is lacking. 525 adolescents (93% African American) awaiting primary care appointments in Baltimore, Maryland were recruited for a study evaluating a substance use screening instrument. Participants were assessed for DSM-5 nicotine, alcohol, and cannabis use disorder, DSM-IV alcohol and cannabis abuse, and DSM-IV dependence for all three substances during the past year using the modified Composite International Diagnostic Interview-2, Substance Abuse Module. Contingency tables examining DSM-5 vs. DSM-IV joint frequency distributions were examined for each substance. Diagnoses were more prevalent using DSM-5 criteria compared with DSM-IV for nicotine (4.0% vs. 2.7%), alcohol (4.6% vs. 3.8%), and cannabis (10.7% vs. 8.2%). Cohen's κ, Somers' d, and Cramer's V ranged from 0.70 to 0.99 for all three substances. Of the adolescents categorized as "diagnostic orphans" under DSM-IV, 7/16 (43.8%), 9/29 (31.0%), and 13/36 (36.1%) met criteria for DSM-5 disorder for nicotine, alcohol, and cannabis, respectively. Additionally, 5/17 (29.4%) and 1/21 (4.8%) adolescents who met criteria for DSM-IV abuse did not meet criteria for a DSM-5 diagnosis for alcohol and cannabis, respectively. Categorizing adolescents using DSM-5 criteria may result in diagnostic net widening-particularly for cannabis use disorders-by capturing adolescents who were considered diagnostic orphans using DSM-IV criteria. Future research examining the validity of DSM-5 substance use disorders with larger and more diverse adolescent samples is needed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Expression of group III metabotropic glutamate receptors in the reproductive system of male mice.

2016-03-01

Although the presence of metabotropic glutamate (mGlu) receptors in the central nervous system is well documented, they have recently been found in peripheral and non-neuronal tissues. In the present study we investigated the expression of group III mGlu receptors in the reproductive system of male mice. Reverse transcription-polymerase chain reaction analysis revealed the presence of mGlu6, mGlu7 and mGlu8 (but not mGlu4) receptor transcripts in testes and epididymides from adult mice. In addition, expression of mGlu6 (Grm6) and mGlu8 receptor (Grm8) mRNA was detected in spermatozoa isolated from the vas deferens. The vas deferens was found to contain only mGlu7 receptor (Grm7) mRNA, which was particularly intense in 21-day-old male mice. In penile homogenates, only the mGlu7 receptor signal was detected. Genetic ablation of the mGlu7 receptor in males led to fertility disorders manifested by decreased insemination capability as well as deterioration of sperm parameters, particularly sperm motility, vitality, sperm membrane integrity and morphology, with a simultaneous increase in sperm concentration. These results indicate that constitutively expressed mGlu receptors in the male reproductive system may play an important role in ejaculation and/or erection processes, as well as in the formation and maturation of spermatozoa.

Impulsive traits and 5-HT2A receptor promoter polymorphism in alcohol dependents: possible association but no influence of personality disorders.

Impulsive behavior in alcoholics puts them at serious risk of severer course of disease and has been related to the serotonergic neurotransmission dysfunction. The aim of this study is to investigate the association between impulsive aggression in alcohol dependents with regard to the G-1438A polymorphism in the promoter region of the 5-HT2A receptor gene. Furthermore, we investigated the statistical interaction between 5-HT2A alleles, antisocial personality disorder (APD) and impulsive aggression in alcohol dependents. Alcohol dependents were investigated because these personality disorders and impulsive behavior are very frequent in alcohol dependence anf of clinical relevance. One hundred and thirty-five patients of German descent meeting DSM-IV criteria of alcohol dependence were recruited. Blood samples were taken from alcohol dependents to determine 5-HT2A promoter polymorphisms using PCR (polymerase chain reaction) of lymphocyte DNA. Impulsive aggression was assessed using a German version of the Barratt Impulsiveness Scale which was translated and backtranslated. Alcohol dependents were subdivided into low- or high-impulsivity groups using a median split of the Barratt score. APD and borderline personality disorder (BPD) were assessed using the SCID-II interview. The low-impulsivity group was slightly older and showed a later age at alcoholism onset than the highly impulsive group. Alcohol dependents with high impulsive traits showed a significant association with 5-HT2A 1438 A alleles. After excluding alcohol dependents with APD or BPD from the analysis, this association remained significant. Furthermore, no association between APD, BPD and 5-HT2A alleles was noted. Inpatient alcohol dependents showed a significant association between 5-HT2A A alleles and impulsive traits, independent of the presence of APD or BPD. No association was noted between personality disorders and the polymorphism. This is the first report about an association of 5-HT2A promoter

Negative Affect and Excessive Alcohol Intake Incubate during Protracted Withdrawal from Binge-Drinking in Adolescent, But Not Adult, Mice

Directory of Open Access Journals (Sweden)

Kaziya M. Lee

2017-07-01

Full Text Available Binge-drinking is common in underage alcohol users, yet we know little regarding the biopsychological impact of binge-drinking during early periods of development. Prior work indicated that adolescent male C57BL6/J mice with a 2-week history of binge-drinking (PND28-41 are resilient to the anxiogenic effects of early alcohol withdrawal. Herein, we employed a comparable Drinking-in-the-Dark model to determine how a prior history of binge-drinking during adolescence (EtOHadolescents influences emotionality (assayed with the light-dark box, marble burying test, and the forced swim test and the propensity to consume alcohol in later life, compared to animals without prior drinking experience. For additional comparison, adult mice (EtOHadults with comparable drinking history (PND56-69 were subdivided into groups tested for anxiety/drinking either on PND70 (24 h withdrawal or PND98 (28 days withdrawal. Tissue from the nucleus accumbens shell (AcbSh and central nucleus of the amygdala (CeA was examined by immunoblotting for changes in the expression of glutamate-related proteins. EtOHadults exhibited some signs of hyperanxiety during early withdrawal (PND70, but not during protracted withdrawal (PND98. In contrast, EtOHadolescents exhibited robust signs of anxiety-l and depressive-like behaviors when tested as adults on PND70. While all alcohol-experienced animals subsequently consumed more alcohol than mice drinking for the first time, alcohol intake was greatest in EtOHadolescents. Independent of drinking age, the manifestation of withdrawal-induced hyperanxiety was accompanied by reduced Homer2b expression within the CeA and increased Group1 mGlu receptor expression within the AcbSh. The present data provide novel evidence that binge-drinking during adolescence produces a state characterized by profound negative affect and excessive alcohol consumption that incubates with the passage of time in withdrawal. These data extend our prior studies on the

It assesses the feasibility of utilizing various C4-C8 alcohols as fuels for internal combustion engines. Utilizing higher-molecular-weight alcohols as fuels requires careful analysis of their fuel properties. ASTM standards provide fuel property requirements for spark-ignition (SI) and compression-ignition (CI) engines such as the stability, lubricity, viscosity, and cold filter plugging point (CFPP) properties of blends of higher alcohols. Important combustion properties that are studied include laminar and turbulent flame speeds, flame blowout/extinction limits, ignition delay under various mixing conditions, and gas-phase and particulate emissions. The chapter focuses on the combustion of higher alcohols in reciprocating SI and CI engines and discusses higher alcohol performance in SI and CI engines. Finally, the chapter identifies the sources, production pathways, and technologies currently being pursued for production of some fuels, including n-butanol, iso-butanol, and n-octanol.

Full Text Available Introduction: policosanol, a mixture of high molecular weight aliphatic alcohols purified from sugarcane with octacosanol as the main component, shows cholesterol-lowering and antiplatelet effects in addition to an inhibitory effect on type I cicloxygenase. Objective: to determine whether policosanol may inhibit 5-LOX enzyme activity in vitro. Methods: effects on 5-LOX enzyme activities were assessed in rat blood polymorphonuclear leukocytes. Vehicle or Policosanol suspensions (0.6 to 6 000 µg/mL were added to tubes containing the reaction mix and then absorbance changes at 234 nm were measured. Results: added Policosanol inhibited in vitro 5-LOX activity by 30 %, which was not a significant figure but depended on the concentration(r= 0.992; p< 0.05; it was 1 250 µg/mL. Conclusions: policosanol did not significantly inhibit 5-LOX enzyme activity in rat PMNL preparations, so that it does not seem to be a dual inhibitor of COX and-LOX enzymes. This result differs from that found for beeswax alcohols and underlines the different effects of the mixtures of long-chain fatty alcohols purified from the sugarcane and the beeswax.

Extraction of hafnium by 1-phenyl-3-methyl-4-benzoyl-5-pyralozone from aqueous-alcoholic solutions

Extraction of hafnium by 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (HL) in benzene, toluene, chloroform and tetrachloromethane from aqueous-alcoholic solutions of the formal acidity of 2M-HClO 4 was studied. Methyl, ethyl, n- and isopropyl, tert-butyl and allyl alcohol as well as ethylene glycol monomethyl ether and propylene glycol were used as organic components of the mixed aqueous-organic phase. Their presence in some cases resulted in a synergic increase in the distribution ratio of hafnium. The increase is interpreted using the results of a slope analysis and measurements of the alcohol distribution and the relative permittivity of the organic phase. It is suggested that HfL 4 molecules were solvated by alcohol molecules in the organic phase. At high alcohol concentration synergism changed into antagonism. This was caused by changes in the distribution of HL and its interaction with the alcohol in the organic phase. (author)

Clay-Alcohol-Water Dispersions: Anomalous Viscosity Changes Due to Network Formation of Clay Nanosheets Induced by Alcohol Clustering.

Science.gov (United States)

Kimura, Yuji; Haraguchi, Kazutoshi

2017-05-16

Clay-alcohol-water ternary dispersions were compared with alcohol-water binary mixtures in terms of viscosity and optical absorbance. Aqueous clay dispersions to which lower alcohols (ethanol, 1-propanol, 2-propanol, and tert-butanol) were added exhibited significant viscosity anomalies (maxima) when the alcohol content was 30-55 wt %, as well as optical absorbance anomalies (maxima). The maximum viscosity (η max ) depended strongly on the clay content and varied between 300 and 8000 mPa·s, making it remarkably high compared with the viscosity anomalies (2 mPa·s) observed in alcohol-water binary mixtures. The alcohol content at η max decreased as the hydrophobicity of the alcohol increased. The ternary dispersions with viscosity anomalies exhibited thixotropic behaviors. The effects of other hydrophilic solvents (glycols) and other kinds of clays were also clarified. Based on these findings and the average particle size changes, the viscosity anomalies in the ternary dispersions were explained by alcohol-clustering-induced network formation of the clay nanosheets. It was estimated that 0.9, 1.7, and 2.5 H 2 O molecules per alcohol molecule were required to stabilize the ethanol, 2-propanol, and tert-butanol, respectively, in the clay-alcohol-water dispersions.

Full Text Available When we compare the categories about alcohol, and substance-related disorders in DSM-IV and DSM-5, the new category, named addictive disorders is the most striking change. Only gambling disorder have been identified currently in this category. This may be the most remarkable change among the changes in the DSM-5. Because the expansion of the existing diagnostic criteria may cause the assessment of and lsquo;normal behavior' as a disorder. Additionally, withdrawal of caffeine and cannabis are defined in the DSM-5. Disorders collected under the title of substance-related disorders in the DSM-IV were collected under the name of substance-related and addictive disorders in the DSM-5. Specific criterias for substance abuse and substance addiction have been combined into the name of "substance use disorders". In substance abuse, "experienced legal problems" criteria was removed and "a strong desire or urge or craving for substance use" criteria has been introduced. Henceforth, substance abuse is defined as a mild form of substance use disorders in the DSM-5. A change in the prevalence of substance use disorders should be investigated by the new researches.

Excessive alcohol use is the third leading cause of preventable death and is highly correlated with alcohol dependence, a heritable phenotype. Many genetic factors for alcohol dependence have been found, but many remain unknown. In search of additional genetic factors, we examined the association between Diagnostic and StatisticalManual of Mental Disorders, Fourth Edition (DSM-IV) alcohol dependence and all common copy number variations (CNVs) with good reliability in the Study of Addiction: Genetics and Environment (SAGE). All participants in SAGE were interviewed using the Semi-Structured Assessment for the Genetics of Alcoholism, as a part of 3 contributing studies. A total of 2,610 non-Hispanic European American samples were genotyped on the Illumina Human 1M array. We performed CNV calling by CNVPartition, PennCNV, and QuantiSNP, and only CNVs identified by all 3 software programs were examined. Association was conducted with the CNV (as a deletion/duplication) as well as with probes in the CNV region. Quantitative polymerase chain reaction (qPCR) was used to validate the CNVs in the laboratory. CNVs in 6q14.1 (p = 1.04 × 10(-6)) and 5q13.2 (p = 3.37 × 10(-4)) were significantly associated with alcohol dependence after adjusting multiple tests. On chromosome 5q13.2, there were multiple candidate genes previously associated with various neurological disorders. The region on chromosome 6q14.1 is a gene desert that has been associated with mental retardation and language delay. The CNV in 5q13.2 was validated, whereas only a component of the CNV on 6q14.1 was validated by qPCR. Thus, the CNV on 6q14.1 should be viewed with caution. This is the first study to show an association between DSM-IV alcohol dependence and CNVs. CNVs in regions previously associated with neurological disorders may be associated with alcohol dependence.

The effect of alcohols on cell membrane proteins has originally been assumed to be mediated by their primary action on membrane lipid matrix. Many studies carried out later on both animal and yeast cells have revealed that ethanol and other alcohols inhibit the functions of various membrane channels, receptors and solute transport proteins, and a direct interaction of alcohols with these membrane proteins has been proposed. Using our fluorescence diS-C3 (3) diagnostic assay for multidrug-resistance pump inhibitors in a set of isogenic yeast Pdr5p and Snq2p mutants, we found that n-alcohols (from ethanol to hexanol) variously affect the activity of both pumps. Beginning with propanol, these alcohols have an inhibitory effect that increases with increasing length of the alcohol acyl chain. While ethanol does not exert any inhibitory effect at any of the concentration used (up to 3%), hexanol exerts a strong inhibition at 0.1%. The alcohol-induced inhibition of MDR pumps was detected even in cells whose membrane functional and structural integrity were not compromised. This supports a notion that the inhibitory action does not necessarily involve only changes in the lipid matrix of the membrane but may entail a direct interaction of the alcohols with the pump proteins. © 2013 Federation of European Microbiological Societies.

Chronic alcohol binging injures the liver and other organs by reducing NAD⁺ levels required for sirtuin's deacetylase activity.

Science.gov (United States)

French, Samuel W

2016-04-01

NAD(+) levels are markedly reduced when blood alcohol levels are high during binge drinking. This causes liver injury to occur because the enzymes that require NAD(+) as a cofactor such as the sirtuin de-acetylases cannot de-acetylate acetylated proteins such as acetylated histones. This prevents the epigenetic changes that regulate metabolic processes and which prevent organ injury such as fatty liver in response to alcohol abuse. Hyper acetylation of numerous regulatory proteins develops. Systemic multi-organ injury occurs when NAD(+) is reduced. For instance the Circadian clock is altered if NAD(+) is not available. Cell cycle arrest occurs due to up regulation of cell cycle inhibitors leading to DNA damage, mutations, apoptosis and tumorigenesis. NAD(+) is linked to aging in the regulation of telomere stability. NAD(+) is required for mitochondrial renewal. Alcohol dehydrogenase is present in every visceral organ in the body so that there is a systemic reduction of NAD(+) levels in all of these organs during binge drinking. Copyright © 2016.

Objective: The purpose of this study was to examine prevalences and concordances between Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), and Fifth Edition (DSM-5) substance use disorders (SUDs) in a newly completed U.S. epidemiologic survey. Method: The National Epidemiologic Survey on Alcohol and Related Conditions–III surveyed 36,309 civilian, noninstitutionalized adults. SUDs were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule–5. Concordances between DSM-IV and DSM-5 disorders were assessed using kappa statistics. Results: Prevalences of past-year substance-specific DSM-5 disorders (2+ criteria) were modestly higher than those of DSM-IV dependence and abuse combined for alcohol, sedatives/tranquilizers, opioids, and heroin, but lower for cannabis, cocaine, and stimulants. Lifetime prevalences were lower under DSM-5. Prevalences were similar between moderate to severe (4+ criteria) DSM-5 disorders and dependence, whereas prevalences of DSM-5 disorders at 3+ criteria (DSM-5 [3+]) were higher, particularly for cannabis. Past-year concordances were excellent for DSM-IV dependence and abuse combined versus any DSM-5 and DSM-IV dependence versus DSM-5 moderate to severe disorders; lifetime concordances were fair to excellent. Past-year concordances between DSM-IV and DSM-5 (3+) were generally similar to or modestly higher than those with any DSM-5 disorder; lifetime concordances were mostly lower. Conclusions: Findings are consistent with those informing the development of DSM-5. Future research should examine differences in patterns between past-year and lifetime disorders, particularly for cannabis. Other questions warranting investigation include whether different combinations of the same numbers of criteria carry different clinical or nosologic implications, whether changes innosology yield changes in treatment demand, and whether changes in characteristics of individuals with DSM-5 SUDs

Alcohol drinking pattern and risk of alcoholic liver cirrhosis

Askgaard, Gro; Grønbæk, Morten; Kjær, Mette S

2015-01-01

BACKGROUND & AIMS: Alcohol is the main contributing factor of alcoholic cirrhosis, but less is known about the significance of drinking pattern. METHODS: We investigated the risk of alcoholic cirrhosis among 55,917 participants (aged 50-64years) in the Danish Cancer, Diet, and Health study (1993......-2011). Baseline information on alcohol intake, drinking pattern, and confounders was obtained from a questionnaire. Follow-up information came from national registers. We calculated hazard ratios (HRs) for alcoholic cirrhosis in relation to drinking frequency, lifetime alcohol amount, and beverage type. RESULTS......: We observed 257 and 85 incident cases of alcoholic cirrhosis among men and women, respectively, none among lifetime abstainers. In men, HR for alcoholic cirrhosis among daily drinkers was 3.65 (95% CI: 2.39; 5.55) compared to drinking 2-4days/week. Alcohol amount in recent age periods (40-49 and 50...

BACKGROUND The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) will soon replace the DSM-IV, which has existed for nearly two decades. The changes in diagnostic criteria have important implications for research and for the clinical care of individuals with Substance Use Disorders (SUDs). METHODS We used the Semi-Structured Assessment for Drug Dependence and Alcoholism to evaluate the lifetime presence of DSM-IV abuse and dependence diagnoses and DSM-5 mild, moderate, or severe SUDs for alcohol, cocaine, opioids, and cannabis in a sample of 7,543 individuals recruited to participate in genetic studies of substance dependence. RESULTS Switches between diagnostic systems consistently resulted in a modestly greater prevalence for DSM-5 SUDs, based largely on the assignment of DSM-5 diagnoses to DSM-IV “diagnostic ophans” (i.e., individuals meeting one or two criteria for dependence and none for abuse, and thus not receiving a DSM-IV SUD diagnosis). The vast majority of these diagnostic switches were attributable to the requirement that only two of 11 criteria be met for a DSM-5 SUD diagnosis. We found evidence to support the omission from DSM-5 of the legal criterion due to its limited diagnostic utility. The addition of craving as a criterion in DSM-5 did not substantially affect the likelihood of an SUD diagnosis. CONCLUSION The greatest advantage of DSM-5 appears to be its ability to capture diagnostic orphans. In this sample, changes reflected in DSM-5 had a minimal impact on the prevalence of SUD diagnoses.

Consumer and public health organizations have called for better labelling on alcoholic drinks. However, there is a lack of consensus about the best elements to include. This review summarizes alcohol labelling policy worldwide and examines available evidence to support enhanced labelling. A literature review was carried out in June-July 2012 on Scopus using the key word 'alcohol' combined with 'allergens', 'labels', 'nutrition information', 'ingredients', 'consumer information' and/or 'warning'. Articles discussing advertising and promotion of alcohol were excluded. A search through Google and the System for Grey Literature in Europe (SIGLE) identified additional sources on alcohol labelling policies, mainly from governmental and organizational websites. Five elements were identified as potentially useful to consumers: (i) a list of ingredients, (ii) nutritional information, (iii) serving size and servings per container, (iv) a definition of 'moderate' intake and (v) a health warning. Alcohol labelling policy with regard to these aspects is quite rudimentary in most countries, with few requiring a list of ingredients or health warnings, and none requiring basic nutritional information. Only one country (Australia) requires serving size and servings per container to be displayed. Our study suggests that there are both potential advantages and disadvantages to providing consumers with more information about alcohol products. Current evidence seems to support prompt inclusion of a list of ingredients, nutritional information (usually only kcal) and health warnings on labels. Standard drink and serving size is useful only when combined with other health education efforts. A definition of 'moderate intake' and recommended drinking guidelines are best suited to other contexts.

In the United Kingdom, alcohol warning labels are the subject of a voluntary agreement between industry and government. In 2011, as part of the Public Health Responsibility Deal in England, the industry pledged to ensure that 80% of products would have clear, legible health warning labelling, although an analysis commissioned by Portman found that only 57.1% met best practice. We assessed what proportion of alcohol products now contain the required health warning information, and its clarity and placement. Survey of alcohol labelling data. United Kingdom. Analysis of the United Kingdom's 100 top-selling alcohol brands (n = 156 individual products). We assessed the product labels in relation to the presence of five labelling elements: information on alcohol units, government consumption guidelines, pregnancy warnings, reference to the Drinkaware website and a responsibility statement. We also assessed the size, colour and placement of text, and the size and colouring of the pregnancy warning logo. The first three (required) elements were present on 77.6% of products examined. The mean font size of the Chief Medical Officer's (CMO) unit guidelines (usually on the back of the product) was 8.17-point. The mean size of pregnancy logos was 5.95 mm. The pregnancy logo was on average smaller on wine containers. The UK Public Health Responsibility Deal alcohol labelling pledge has not been fully met. Labelling information frequently falls short of best practice, with font and logos smaller than would be accepted on other products with health effects. © 2015 Society for the Study of Addiction.

MGluR5 mediates the interaction between late-LTP, network activity, and learning.

Directory of Open Access Journals (Sweden)

Arthur Bikbaev

2008-05-01

Full Text Available Hippocampal synaptic plasticity and learning are strongly regulated by metabotropic glutamate receptors (mGluRs and particularly by mGluR5. Here, we investigated the mechanisms underlying mGluR5-modulation of these phenomena. Prolonged pharmacological blockade of mGluR5 with MPEP produced a profound impairment of spatial memory. Effects were associated with 1 a reduction of mGluR1a-expression in the dentate gyrus; 2 impaired dentate gyrus LTP; 3 enhanced CA1-LTP and 4 suppressed theta (5-10 Hz and gamma (30-100 Hz oscillations in the dentate gyrus. Allosteric potentiation of mGluR1 after mGluR5 blockade significantly ameliorated dentate gyrus LTP, as well as suppression of gamma oscillatory activity. CA3-lesioning prevented MPEP effects on CA1-LTP, suggesting that plasticity levels in CA1 are driven by mGluR5-dependent synaptic and network activity in the dentate gyrus. These data support the hypothesis that prolonged mGluR5-inactivation causes altered hippocampal LTP levels and network activity, which is mediated in part by impaired mGluR1-expression in the dentate gyrus. The consequence is impairment of long-term learning.

Paradoxical sleep deprivation in rats is considered as an experimental animal model of mania endowed with face, construct, and pharmacological validity. We induced paradoxical sleep deprivation by placing rats onto a small platform surrounded by water. This procedure caused the animal to fall in the water at the onset of REM phase of sleep. Control rats were either placed onto a larger platform (which allowed them to sleep) or maintained in their home cage. Sleep deprived rats showed a substantial reduction in type-2 metabotropic glutamate (mGlu2) receptors mRNA and protein levels in the hippocampus, but not in the prefrontal cortex or corpus striatum, as compared to both groups of control rats. No changes in the expression of mGlu3 receptor mRNA levels or mGlu1α and mGlu5 receptor protein levels were found with exception of an increase in mGlu1α receptor levels in the striatum of SD rats. Moving from these findings we treated SD and control rats with the selective mGlu2 receptor enhancer, BINA (30mg/kg, i.p.). SD rats were also treated with sodium valproate (300mg/kg, i.p.) as an active comparator. Both BINA and sodium valproate were effective in reversing the manic-like phenotype evaluated in an open field arena in SD rats. BINA treatment had no effect on motor activity in control rats, suggesting that our findings were not biased by a non-specific motor-lowering activity of BINA. These findings suggest that changes in the expression of mGlu2 receptors may be associated with the enhanced motor activity observed with mania. Copyright © 2016 Elsevier Ltd. All rights reserved.

The Combination of Marketed Antagonists of α1b-Adrenergic and 5-HT2A Receptors Inhibits Behavioral Sensitization and Preference to Alcohol in Mice: A Promising Approach for the Treatment of Alcohol Dependence.

Directory of Open Access Journals (Sweden)

Fabrice Trovero

Full Text Available Alcohol-dependence is a chronic disease with a dramatic and expensive social impact. Previous studies have indicated that the blockade of two monoaminergic receptors, α1b-adrenergic and 5-HT2A, could inhibit the development of behavioral sensitization to drugs of abuse, a hallmark of drug-seeking and drug-taking behaviors in rodents. Here, in order to develop a potential therapeutic treatment of alcohol dependence in humans, we have blocked these two monoaminergic receptors by a combination of antagonists already approved by Health Agencies. We show that the association of ifenprodil (1 mg/kg and cyproheptadine (1 mg/kg (α1-adrenergic and 5-HT2 receptor antagonists marketed as Vadilex ® and Periactine ® in France, respectively blocks behavioral sensitization to amphetamine in C57Bl6 mice and to alcohol in DBA2 mice. Moreover, this combination of antagonists inhibits alcohol intake in mice habituated to alcohol (10% v/v and reverses their alcohol preference. Finally, in order to verify that the effect of ifenprodil was not due to its anti-NMDA receptors property, we have shown that a combination of prazosin (0.5 mg/kg, an α1b-adrenergic antagonist, Mini-Press ® in France and cyproheptadine (1 mg/kg could also reverse alcohol preference. Altogether these findings strongly suggest that combined prazosin and cyproheptadine could be efficient as a therapy to treat alcoholism in humans. Finally, because α1b-adrenergic and 5-HT2A receptors blockade also inhibits behavioral sensitization to psychostimulants, opioids and tobacco, it cannot be excluded that this combination will exhibit some efficacy in the treatment of addiction to other abused drugs.

The liquids (e-liquids) used in an electronic cigarette (e-cigarette) contain myriad chemicals without adequate human inhalation safety data. Furthermore, the absence of e-liquid labeling requirements poses a formidable challenge to understanding how e-liquid constituents may promote nicotine addiction and/or have independent or synergistic biological effects when combined with nicotine. Ethyl alcohol is such a constituent, but has received little scientific interest in this context. Using a randomized, double blind, crossover design, acute changes in subjective drug effects, motor performance and biochemical measures of alcohol and nicotine intake were evaluated after directed and ad lib puffing from two commercially available e-liquids containing nicotine (8 mg/ml), vanilla flavor and either 23.5% (high) or 0.4% (trace) alcohol. While no differences in subjective drug effects were observed between alcohol conditions, performance on the Purdue Pegboard Dexterity Test (PPDT) improved under the trace, but not under the 23.5% alcohol condition. Although plasma alcohol levels remained undetectable during testing, urine ethyl glucuronide (EtG), an alcohol metabolite, became measurable in three participants after puffing from the 23.5% alcohol e-cigarette. Brief use of a widely available type of e-cigarette containing an e-liquid purchased from an internet vendor can negatively impact psychomotor performance and in some instances, produce detectable levels of a urine alcohol metabolite. Given the widespread and unregulated use of e-cigarettes, especially by youth and other vulnerable populations, further studies are needed to evaluate both the acute safety and long-term health risks of using alcohol-containing e-cigarettes.

Cerebellar granule cell GABAA receptor responses to alcohol vary as a function of alcohol consumption phenotype, representing a potential neural mechanism for genetic predilection for alcohol abuse (Kaplan et al., 2013; Mohr et al., 2013). However, there are numerous molecular targets of alcohol in the cerebellum, and it is not known how they interact to affect cerebellar processing during consumption of socially relevant amounts of alcohol. Importantly, direct evidence for a causative role of the cerebellum in alcohol consumption phenotype is lacking. Here we determined that concentrations of alcohol that would be achieved in the blood after consumption of 1-2 standard units (9 mm) suppresses transmission through the cerebellar cortex in low, but not high, alcohol consuming rodent genotypes (DBA/2J and C57BL/6J mice, respectively). This genotype-selective suppression is mediated exclusively by enhancement of granule cell GABAA receptor currents, which only occurs in DBA/2J mice. Simulating the DBA/2J cellular phenotype in C57BL/6J mice by infusing the GABAA receptor agonist, 4,5,6,7-tetrahydroisoxazolo-[5,4-c]pyridine-3-ol hydrochloride, into cerebellar lobules IV-VI, in vivo, significantly reduced their alcohol consumption and blood alcohol concentrations achieved. 4,5,6,7-Tetrahydroisoxazolo-[5,4-c]pyridine-3-ol hydrochloride infusions also significantly decreased sucrose consumption, but they did not affect consumption of water or general locomotion. Thus, genetic differences in cerebellar response to alcohol contributes to alcohol consumption phenotype, and targeting the cerebellar GABAA receptor system may be a clinically viable therapeutic strategy for reducing excessive alcohol consumption. Alcohol abuse is a leading cause of preventable death and illness; and although alcohol use disorders are 50%-60% genetically determined, the cellular and molecular mechanisms of such genetic influences are largely unknown. Here we demonstrate that genetic differences in

The objective of this investigation was to establish the ability of the Secure Continuous Remote Alcohol Monitoring (SCRAM) alcohol sensor to detect different levels of self-reported alcohol consumption, and to determine whether gender and body mass index, alcohol dependence, bracelet version, and age of bracelet influenced detection of alcohol use. Heavy drinking adults (N = 66, 46% female) wore the SCRAM for 1-28 days and reported their alcohol use in daily Web-based surveys. Participant reports of alcohol use were matched with drinking episodes identified from bracelet readings. On days when bracelets were functional, 690 drinking episodes were reported and 502 of those episodes (72.8%) were detected using sensor data. Using generalized estimating equations, we found no gender differences in detection of reported drinking episodes (77% for women, 69% for men). In univariate analyses, at the level of fewer than 5 drinks, women's episodes were more likely to be detected, likely because of the significantly higher transdermal alcohol concentration levels of these episodes, whereas at the level of 5 or more drinks, there was no gender difference in detection (92.6% for women, 93.4% for men). In multivariable analyses, no variables other than number of drinks significantly predicted alcohol detection. In summary, the SCRAM sensor is very good at detecting 5 or more drinks; performance of the monitor below this level was better among women because of their higher transdermal alcohol concentration levels. Individual person characteristics and bracelet features were not related to detection after number of drinks was included. Minimal bracelet malfunctions were noted.

Increasing alcohol taxes has proven effective in reducing alcohol consumption, but the effects of alcohol sales taxes on sales of specific alcoholic beverages have received little research attention. Data on sales are generally less subject to reporting biases than self-reported patterns of alcohol consumption. We aimed to assess the effects of Maryland's July 1, 2011 three percentage point increase in the alcohol sales tax (6-9%) on beverage-specific and total alcohol sales. Using county-level data on Maryland's monthly alcohol sales in gallons for 2010-2012, by beverage type, multilevel mixed effects multiple linear regression models estimated the effects of the tax increase on alcohol sales. We controlled for seasonality, county characteristics, and national unemployment rates in the main analyses. In the 18 months after the tax increase, average per capita sales of spirits were 5.1% lower (p sales were 3.2% lower (p sales were 2.5% lower (p sales trends in the 18 months prior to the tax increase. Overall, the alcohol sales tax increase was associated with a 3.8% decline in total alcohol sold relative to what would have been expected based on sales in the prior 18 months (p increased alcohol sales taxes may be as effective as excise taxes in reducing alcohol consumption and related problems. Sales taxes also have the added advantages of rising with inflation and taxing the highest priced beverages most heavily.

Alcohol abuse and related disorders treatment of alcohol dependence

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Alcohol abuse and alcoholism are the leading causes of worse health and increased mortality rates. Excessive alcohol consumption is the third leading cause of the global burden of diseases and a leading factor for lower lifespan and higher mortality. Alcohol abuse decreases working capacity and efficiency and requires the increased cost of the treatment of alcohol-induced disorders, which entails serious economic losses. The unfavorable medical and social consequences of excessive alcohol use determine the importance of effective treatment for alcoholism. The goals of rational pharmacotherapy of alcohol dependence are to enhance GABA neurotransmission, to suppress glutamate neurotransmission, to act on serotonin neurotransmission, to correct water-electrolyte balance, and to compensate for thiamine deficiency. Alcoholism treatment consists of two steps: 1 the prevention and treatment of alcohol withdrawal syndrome and its complications (withdrawal convulsions and delirium alcoholicum; 2 antirecurrent (maintenance therapy. Benzodiazepines are the drugs of choice in alleviating alcohol withdrawal and preventing its convulsive attacks and delirium alcoholicum. Diazepam and chlordiazepoxide are most commonly used for this purpose; the safer drugs oxazepam and lorazepam are given to the elderly and patients with severe liver lesions. Anticonvulsants having normothymic properties, such as carbamazepine, valproic acid, topiramate, and lamotrigine, are a definite alternative to benzodiazepines. The traditional Russian clinical practice (clearance detoxification has not a scientific base or significant impact on alcohol withdrawal-related states in addicts. Relapse prevention and maintenance therapy for alcohol dependence are performed using disulfiram, acamprosate, and naltrexone; since 2013 the European Union member countries have been using, besides these agents, nalmefene that is being registered in Russia.

To investigate the characteristics of alcohol use among Japanese adults and prevalence of alcohol dependence in Japan, we conducted a nationwide survey on alcohol drinking behavior and alcohol dependence among Japanese adults using a representative sampling method. We sampled 3500 adults from throughout the entire country using a stratified random sampling method with two-step stratification, and carried out a home visit interview survey. A total of 2547 people (72.8%) responded to the survey. The survey period was June, 2003. The questionnaire contained questions about the frequency and quantity of alcohol use, 'hazardous use of alcohol' and 'alcohol dependence' according to the ICD-10 definition, several screening scales on problem use of alcohol (CAGE, KAST, AUDIT), life-time prevalence of 24 alcohol related diseases, smoking status, dysgryphia, and nightcap drinking. The number of respondents was, 1184 males, and 1363 females. Lifetime alcohol drinking, and weekly drinking, and daily drinking rates were 95.1%, 64.4%, and 36.2% for males, 79.0%, 27.5%, and 7.5% for females, respectively. Average daily alcohol consumption was 3.7 units for males, and 2.0 units for females (1 unit = 10 g pure alcohol). The proportion of drinkers who drank alcohol 4 units or more daily was 28.9% for males, and 7.6% for females, and that for 6 units or more was 12.7% for males, and 3.4% for females. The proportion of flasher was 41.2% for males, and 35.0% for females. Among screening questions, problem drinking was most frequently identified using AUDIT (score 12 points or more, 150 persons), followed by KAST (2 points or more, 100 persons) and CAGE (2 points or more, 98 persons). The number of subjects who met the ICD-10 criteria for alcohol dependence was 24, while the number who engaged in hazardous alcohol use was 64. This study revealed that problem drinking and alcohol dependence are a serious problem in Japanese general population. The problem of females drinking may be

Full Text Available According to WHO, the world takes place every year approximately 500 000 suicides and suicide attempts of 7 million. Since 1994, Russia ranks 2nd in the world after Lithuania, in the level of suicides, and is among the countries with the linear dependence of frequency of suicides on the level of alcohol consumption.Purpose. Install a quantitative connection between the frequency of suicide with alcohol consumption and mortality from alcoholism in the world.Material and method. For studies we used the mortality coefficient (MK from suicide and alcohol abuse (number of people/100 thousand of age standardized the population in 159 countries according to the WHO in 2004, the average daily consumption levels of alcoholic beverages: spirits, wine and beer (g/person/day according to the FAO (Food and Agriculture Organization of the United Nations. For data analysis we used correlation and regression methods.Results. We found significant positive correlation of mortality coefficient (MK from suicide for men and women with consumption of alcoholic beverages (spirits, wine and beer and mortality from alcoholism. The gender differences are revealed. Included in the regression model independent variables (levels of alcohol consumption and mortality from alcoholism explain 66% and 52% of the variability in the frequency of suicides of men and women (dependent variables. A complete rejection of the consumption of alcohol reduces the MK from suicide of men in the world at 39.5 percent, in Russia — at 76.5%; women — 37.9%, in Russia — by 54.3%. According to the regression analysis the average daily level of consumption of strong alcohol in the world is 10.4 g (3.8 kg per year for men, in Russia — 91.8 g (of 33.5 kg per year. The increase in the consumption of strong alcohol to 3 g per day (1 kg per year increases the MK from suicide in men up to 10.8% (1.6 people in the world, in Russia — 2.4% (1.6 people.

In spite of many reports in the literature concerning with oxidation of benzylic alcohols to carbonyl compounds with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in stoichiometric amounts or even more, we surprisingly found that benzylic alcohols are directly oxidized to oximes using a catalytic amount of DDQ in the presence of hydroxylamine hydrochloride under solvent-free conditions. The present tandem catalytic method can be efficiently used for preparation of oximes in the presence of some other functional groups with excellent chemoselectivity

Cloninger suggested that type II alcoholism was associated with higher novelty seeking and less harm avoidance behaviors, which was similar to antisocial alcoholism. Most previous studies have failed to recruit subjects that have antisocial personality disorder without alcoholism due to the high coexisting likelihood of having antisocial personality disorder with alcoholism in the majority of the examined populations. Thus, recruitment of individuals with antisocial non-alcoholism (antisocial personality disorder) served as an important control group in examining Cloninger's hypothesis. Due to the documented protective effects against alcoholism of ALDH2*1/*2 or *2/*2 genotype among the Han Chinese population, we recruited antisocial non-alcoholics from the Han Chinese population in Taiwan to verify Cloninger's hypotheses. A total of 127 Han Chinese subjects were recruited who met the diagnosis of antisocial alcoholism (n = 43) or antisocial non-alcoholism (n = 84). We found that the antisocial alcoholism group scored higher on the novelty seeking behavior than did the antisocial non-alcoholism group (t = 2.61, P = 0.01), but no difference was observed on the harm avoidance dimension between these two groups (t = 0.15, P = 0.88). In the novelty seeking scores, after stratification of DRD2 TaqI A genotypes, only a significant difference in 5-HTTLPR polymorphisms between antisocial alcoholics and antisocial non-alcoholics was found, indicating an interaction between DRD2 TaqI A1+ (include A1/A1 or A1/A2) and 5-HTTLPR S/S genotype (t = 2.75, P = 0.01) However, no significant difference was found in the harm avoidance personality trait between these two groups of Han Chinese in Taiwan.

Background Existing information on consequences of the DSM-5 revision for diagnosis of alcohol use disorders (AUD) has gaps, including missing information critical to understanding implications of the revision for clinical practice. Methods Data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were used to compare AUD severity, alcohol consumption and treatment, sociodemographic and health characteristics and psychiatric comorbidity among individuals with DSM-IV abuse versus DSM-5 moderate AUD and DSM-IV dependence versus DSM-5 severe AUD. For each pair of disorders, we additionally compared three mutually exclusive groups: individuals positive solely for the DSM-IV disorder, those positive solely for the DSM-5 disorder and those positive for both. Results Whereas 80.5% of individuals positive for DSM-IV dependence were positive for DSM-5 severe AUD, only 58.0% of those positive for abuse were positive for moderate AUD. The profiles of individuals with DSM-IV dependence and DSM-5 severe AUD were almost identical. The only significant (pDSM-5 moderate AUD and DSM-IV abuse differed substantially. The former endorsed more AUD criteria, had higher rates of physiological dependence, were less likely to be White and male, had lower incomes, were less likely to have private and more likely to have public health insurance, and had higher levels of comorbid anxiety disorders than the latter. Conclusions Similarities between the profiles of DSM-IV and DSM-5 AUD far outweigh differences; however, clinicians may face some changes with respect to appropriate screening and referral for cases at the milder end of the AUD severity spectrum, and the mechanisms through which these will be reimbursed may shift slightly from the private to public sector.

To examine the National Institute on Alcohol Abuse and Alcoholism Youth Guide alcohol frequency screening thresholds when applied to Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnostic criteria, and to describe alcohol use patterns and alcohol use disorder (AUD) characteristics in rural youth from primary care settings. Adolescents (n = 1193; ages 12 through 20 years) visiting their primary care practitioner for outpatient visits in six rural primary care clinics were assessed prior to their practitioner visit. A tablet computer collected youth self-report of past-year frequency and quantity of alcohol use and DSM-5 AUD symptoms. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were determined. For early adolescents (ages 12 through 14 years), 1.9% met DSM-5 criteria for past-year AUD and ≥3 days with alcohol use in the past year yielded a screen for DSM-5 with optimal psychometric properties (sensitivity: 89%; specificity: 95%; PPV: 37%; NPV: 100%). For middle adolescents (ages 15 through 17 years), 9.5% met DSM-5 AUD criteria, and ≥3 past year drinking days showed optimal screening results (sensitivity: 91%; specificity: 89%; PPV: 50%; NPV: 99%). For late adolescents (ages 18 through 20 years), 10.0% met DSM-5 AUD criteria, and ≥12 past year drinking days showed optimal screening results (sensitivity: 92%; specificity: 75%; PPV: 31%; NPV: 99%). The age stratified National Institute on Alcohol Abuse and Alcoholism frequency thresholds also produced effective results. In rural primary care clinics, 10% of youth over age 14 years had a past-year DSM-5 AUD. These at-risk adolescents can be identified with a single question on alcohol use frequency.

This study aimed to establish the scale of alcohol-related injuries originating in the home. Despite recent media and public attention on alcohol-related injuries occurring at licensed venues, many occur in other locations including the home. A retrospective observational study. Emergency department surveillance data sourced from the Queensland Injury Surveillance Unit were interrogated for alcohol-related emergency department presentations from 2003-2012 (n = 12,296). Descriptive analysis was undertaken to assess alcohol involvement in injury, and analysis of variance was used to determine the differences among group means and their associated presentations. The relationship between demographic variables and injury location was assessed using p value of domestic violence by spouse or partner (n = 510), 59·5% occurred 'at home'. This is the first study to investigate alcohol-related injuries occurring at home. The home accounts for a greater proportion of injuries than the frequently assessed licensed premises location. Further research is required to validate these findings in a wider setting. A public health campaign is required to minimise harm associated with alcohol-related injuries in the home, and nurses are positioned to inform health policy makers around this issue. Furthermore, emergency department nurses are in a unique position to provide brief interventions around safe alcohol consumption and injury prevention. © 2016 John Wiley & Sons Ltd.

Highlights: • Cassava alcohol residue was first pretreated by hydrothermal reaction. • Hydrothermal pretreatment was optimized by RSM for co-utilization of C-5 and C-6 sugars. • The maximum xylose yield and the highest enzymatic digestibility were not obtained at the same conditions. • Optimum pretreatment conditions were at 193 °C, with 11.4% solids and for 51 min. • The optimal theoretical ethanol production was 69.5 mg/g raw materials by co-utilization of C-5 and C-6 sugars. - Abstract: Hydrothermal reaction was first applied to pretreat cassava alcohol residue for realizing the co-utilization of xylose and glucose to assume fermentation ethanol. This work focused on the influence of hydrothermal pretreatment conditions on ethanol production. Hydrothermal reaction was used to explore the maximum xylose and glucose yields, in respect to reaction temperature (120–240 °C), solid-liquid ratio (0.023–0.150) and reaction time (15–120 min). The results showed that the suitable conditions were at 180–200 °C, for 45–60 min and with 10–12.5% solids. In this range, the conjunct of xylose and glucose would reach the maximum, which can make full use of hemicellulose and cellulose in cassava alcohol residue. According to the results, respond surface methodology (RSM) based on Box-Behnken design was used to further optimize the three independent variables for the highest ethanol by co-utilization of xylose and glucose. RSM revealed that the effect of temperature on ethanol production was much more significant than the effect of reaction time and solid-liquid ratio, and the highest ethanol production was 70.6 mg/g that was close to the experiment value of 69.5 mg/g at 193 °C for 51 min and with 11.5% solids. Furthermore, the crystallinity and morphology of the untreated and pretreated cassava alcohol residue were investigated to assess the effect of hydrothermal pretreatment by scanning electron microscope (SEM) and X-ray diffraction (XRD

Alcohol Preferences and Event-Related Potentials to Alcohol Images in College Students.

Thurin, Kyle; Ceballos, Natalie A; Graham, Reiko

2017-11-01

Research on attentional biases to alcohol images has used heterogeneous sets of stimuli (e.g., an isolated beer can or a group of people drinking). However, alcoholic beverage preferences play an important part in determining an individual's alcohol use pattern and may influence attentional biases, especially for inexperienced drinkers. The current study examined whether alcoholic beverage preferences affect event-related potential (ERP) indices of cue reactivity to different types of alcohol images (e.g., beer, wine, and distilled spirits) in heavy episodic drinkers. ERPs were recorded in 14 heavy episodic drinkers (7 male) who completed a Go/No-Go task using preferred and nonpreferred alcohol images with nonalcoholic beverage images as controls. Larger N2 amplitudes for preferred alcohol images were observed relative to control images and to nonpreferred alcohol images, indicating increased attentional capture by preferred beverages. P3 amplitudes and latencies were not sensitive to preferences, but latencies were delayed and amplitudes were enhanced on No-Go trials (i.e., trials requiring response inhibition). These results suggest that alcoholic beverage preference is a factor influencing alcohol cue reactivity in heavy-episodic-drinking college students. This information has methodological significance and may also be applied to improve treatment and prevention programs that focus on attentional bias modification and inhibitory control training.

Saccharin fading is not required for the acquisition of alcohol self-administration, and can alter the dynamics of cue-alcohol memory reconsolidation.

Puaud, Mickaël; Ossowska, Zofia; Barnard, Jordan; Milton, Amy L

2018-04-01

Animal models of alcohol-seeking are useful for understanding alcohol addiction and for treatment development, but throughput in these models is limited by the extensive pretraining required to overcome the aversive taste of ethanol. Work by Augier et al. (Psychopharmacology 231: 4561-4568, 2014) indicates that Wistar rats will self-administer alcohol without water deprivation, exposure to sweetened ethanol solutions or intermittent access to ethanol. We sought to replicate and extend the work of Augier et al. by comparing the acquisition of instrumental self-administration of ethanol in Lister-Hooded rats that had been previously saccharin faded (SF group) or not (NSF group). We also aimed to determine whether NMDA receptor antagonism with MK-801, given at memory reactivation, reduced subsequent ethanol-seeking behaviour in both groups of animals. Finally, we assessed the ethanol preference of SF and NSF rats using the two-bottle choice procedure. Both SF and NSF groups acquired instrumental self-administration of ethanol, though SF rats consumed fewer of the earned reinforcers. MK-801, given at memory reactivation, had different effects on NSF and SF rats: impairing the capacity of an ethanol-paired conditioned stimulus (CS) to support reinstatement in NSF rats, and enhancing it in SF rats. Finally, neither SF nor NSF rats showed a preference for ethanol. Our data support those of Augier et al. (Psychopharmacology 231: 4561-4568, 2014) that pretraining is unnecessary for rats to acquire instrumental self-administration of ethanol. Indeed, saccharin fading may produce a weaker memory that extinguishes more readily, thus accounting for the different effects of MK-801 on SF and NSF rats.

Identification of a cys-ser substitution in the 5-HT{sub 2C} (HTR2C) receptor gene and allelic association to violent behavior and alcoholism

Several lines of evidence suggest that brain serotonergic functions, including behavioral and neurochemical responses to 5-HT{sub 2C} agonist, are abnormal in some individuals with alcoholism and aggressive behaviors. The aim of the present study was to identify coding sequence variants in the human 5-HT{sub 2C} receptor gene which may cause abnormal or variant function of this receptor. Using SSCP analysis, a non-conservative cys-ser substitution was found in the 5-HT{sub 2C} receptor (designated 5-HT{sub 2Ccys} and 5-HT{sub 2Cser}). The polymorphism was typed in CEPH families to genetically map the gene. To test for association of the variant to alcoholism, violent behavior and serotonin function, the 5-HT{sub 2C} genotypes of 151 non-related Finnish male alcoholic violent offenders and impulsive fire setters and 127 Finnish psychiatrically interviewed healthy male volunteers were determined. CSF 5-HIAA concentrations were available for 74 alcoholic violent offenders and 25 healthy volunteers. Linkage analysis placed the 5-HT{sub 2C} gene on Xq21, a region that has been previously shown to contain genes for several mental retardation syndromes. The 5-HT{sub 2Ccys}/5-HT{sub 2Cser} genotype frequencies in alcoholic violent offenders and controls differed significantly (0.90/0.10 and 0.82/0.18, respectively, P=0.048). The association was found to be strongest in the violent offenders who did not fulfill the criteria for antisocial personality disorder (5-HT{sub 2Ccys}/5-HT{sub 2Cser} 0.93/0.07, p=0.021). No association was found between CSF 5-HIAA concentrations and 5-HT{sub 2C} genotype. These results implicate a 5-HT{sub 2C} receptor amino acid substitution in predisposition to alcohol abuse and violent behavior in a subgroup of alcoholics.

Full Text Available Objective: to analyze the influence of alcohol intake during lactation in alcoholism onset. Methods: descriptive research with intentional convenient sample of 33 people addicted to alcohol and their mothers which assessed the correlation between the consumption of alcohol ingested using the instruments Cut down, Annoyde by criticims, Guilty and Eye-opener, and Tolerance, Annoyed, Cut down and Eye-opener. Results: addicts are men, young, single, with low level of education and income between one and five minimum wages. Among the patients who consider themselves alcoholics, 55.5% had mothers who considered themselves alcoholics and 60.0% of them had consumed alcohol during lactation, but this correlation was not significant. Conclusion: a positive correlation between alcohol consumption by mothers during breastfeeding and addiction of their children in adulthood was not found.

The risk of adverse events among alcohol-interactive medication users can occur with one standard alcoholic drink. Research on the extent to which this occurs is scant. To examine the prevalence and correlates of concurrent alcohol and alcohol-interactive (AI) medication use across different levels of risk for an alcohol-related adverse event in a nationally representative sample of American adults. Cross-sectional analysis of past year, self-reported drinking history as well as past month, self-reported and visually inspected prescription drug use data from the 1999-2000 and 2001-2002 NHANES questionnaire section (n = 8,246). Medications were considered AI if concurrent use of alcohol and the prescription drug could intensify the effects of alcohol, resulting in increased sedation, drowsiness, or dizziness. Weighted prevalence estimates and polytomous logistic regression accounted for the complex survey design. Overall, 13.5% took prescription AI medications, of which 5.6% reported alcohol consumption of three or more drinks on each drinking occasion. Correlates of such use were being a man [adjusted odds ratio (AOR): 4.37; 95% confidence interval (CI): 1.84-10.35], between the ages of 20 and 54 (AOR=12.28; 95% CI: 3.12-48.25), and currently smoking (AOR: 2.61; 95% CI: 1.28-5.29), with alcohol-abstaining AI users as the referent group. Combining alcohol and AI medications is a common phenomenon, and the risk of alcohol-related adverse drug events may be nontrivial. Screening for alcohol use before prescribing AI medications would be prudent. Better communication regarding the dangers of mixing alcohol with AI medications is warranted.

There is strong scientific evidence supporting the effectiveness of increasing alcohol taxes for reducing excessive alcohol consumption and related problems. Opponents have argued that alcohol tax increases lead to job losses. However, there has been no comprehensive economic analysis of the impact of alcohol taxes on employment. To fill this gap, a regional macroeconomic simulation model was used to assess the net impact of two hypothetical alcohol tax increases (a 5-cent per drink excise tax increase and a 5% sales tax increase on beer, wine, and distilled spirits, respectively) on employment in Arkansas, Florida, Massachusetts, New Mexico, and Wisconsin. The model accounted for changes in alcohol demand, average state income, and substitution effects. The employment impact of spending the new tax revenue on general expenditures versus health care was also assessed. Simulation results showed that a 5-cent per drink additional excise tax on alcoholic beverages with new tax revenues allocated to general expenditures increased net employment in Arkansas (802 jobs); Florida (4583 jobs); Massachusetts (978 jobs); New Mexico (653 jobs); and Wisconsin (1167 jobs). A 5% additional sales tax also increased employment in Arkansas (789 jobs; Florida (4493 jobs); Massachusetts (898 jobs); New Mexico (621 jobs); and Wisconsin (991 jobs). Using new alcohol tax revenues to fund health care services resulted in slightly lower net increases in state employment. The overall economic impact of alcohol tax increases cannot be fully assessed without accounting for the job gains resulting from additional tax revenues. Copyright © 2017 Elsevier Inc.

2018-06-01

Full Text Available Purpose: This study aimed to assess alcohol consumption and the occurrence of alcohol-related seizures in patients with epilepsy within the last 12 months.Methods: In an epilepsy outpatient clinic, a standardized questionnaire was used to collect data retrospectively from consecutive adult epilepsy patients who had been suffering from the disease for at least 1 year. Logistic regression analyses were performed to identify independent predictors.Results: A total of 310 patients with epilepsy were included. Of these, 204 subjects (65.8% consumed alcohol within the last 12 months. Independent predictors for alcohol use were antiepileptic drug monotherapy (OR 1.901 and physicians' advice that a light alcohol intake is harmless (OR 4.102. Seizure worsening related to alcohol consumption was reported by 37 of the 204 patients (18.1% who had used alcohol. All 37 subjects had consumed large quantities of alcohol prior to the occurrence of alcohol-related seizures regardless of their usual alcohol-drinking behavior. The amount of alcohol intake prior to alcohol-related seizures was at least 7 standard drinks, which is equivalent to 1.4 L of beer or 0.7 L of wine. In 95% of cases, alcohol-related seizures occurred within 12 h after cessation of alcohol intake. Independent predictors for alcohol-related seizures were generalized genetic epilepsy (OR 5.792 and chronic heavier alcohol use (OR 8.955.Conclusions: Two-thirds of interviewed subjects had consumed alcohol within the last 12 months. This finding may be an underestimate due to patients' self-reporting and recall error. In all cases, the occurrence of alcohol related-seizures was associated with timely consumption of considerably large amounts of alcohol. Thus, a responsible alcohol intake seems to be safe for most patients with epilepsy. However, subjects with epilepsy and especially those with generalized genetic epilepsy should be made aware of an increased risk for seizures related to heavy

Deracemization of Secondary Alcohols by using a Single Alcohol Dehydrogenase

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. We developed a single-enzyme-mediated two-step approach for deracemization of secondary alcohols. A single mutant of Thermoanaerobacter ethanolicus secondary alcohol dehydrogenase enables the nonstereoselective oxidation of racemic alcohols to ketones, followed by a stereoselective reduction process. Varying the amounts of acetone and 2-propanol cosubstrates controls the stereoselectivities of the consecutive oxidation and reduction reactions, respectively. We used one enzyme to accomplish the deracemization of secondary alcohols with up to >99% ee and >99.5% recovery in one pot and without the need to isolate the prochiral ketone intermediate.

Regulation of Akt and Wnt signaling by the group II metabotropic glutamate receptor antagonist LY341495 and agonist LY379268.

Science.gov (United States)

Sutton, Laurie P; Rushlow, Walter J

2011-06-01

Metabotropic glutamate receptors 2/3 (mGlu(2/3)) have been implicated in schizophrenia and as a novel treatment target for schizophrenia. The current study examined whether mGlu(2/3) regulates Akt (protein kinase B) and Wnt (Wingless/Int-1) signaling, two cascades associated with schizophrenia and modified by antipsychotics. Western blotting revealed increases in phosphorylated Akt (pAkt) and phosphorylated glycogen synthase kinase-3 (pGSK-3) following acute and repeated treatment of LY379268 (mGlu(2/3) agonist), whereas increases in dishevelled-2 (Dvl-2), dishevelled-3 (Dvl-3), GSK-3 and β-catenin were only observed following repeated treatment. LY341495 (mGlu(2/3) antagonist) induced the opposite response compared with LY379268. Co-immunoprecipitation experiments showed an association between the mGlu(2/3) complex and Dvl-2 providing a possible mechanism to explain how the mGlu(2/3) can mediate changes in Wnt signaling. However, there was no association between the mGlu(2/3) complex and Akt suggesting that changes in Akt signaling following LY341495 and LY379268 treatments may not be directly mediated by the mGlu(2/3) . Finally, an increase in locomotor activity induced by LY341495 treatment correlated with increased pAkt and pGSK-3 levels and was attenuated by the administration of the GSK-3 inhibitor, SB216763. Overall, the results suggest that mGlu(2/3) regulates Akt and Wnt signaling and LY379268 treatment has overlapping effects with D(2) dopamine receptor antagonists (antipsychotic drugs). © 2011 The Authors.

The purpose of the present study was to investigate associations between the 7-factor hybrid model of DSM-5 posttraumatic stress disorder (PTSD) symptoms, which includes intrusions, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal symptoms, and alcohol consumption and consequences. A nationally representative sample of 916 trauma-exposed U.S. military veterans were administered the Trauma History Screen, PTSD Checklist-5, and Alcohol Use Disorders Identification Test. Confirmatory factor analyses were conducted to determine associations between the 7-factor hybrid model of PTSD symptoms, and alcohol consumption and consequences. Results revealed that lifetime dysphoric arousal (r=0.31), negative affect (r=0.30), and anhedonia (r=0.29) symptom clusters were most strongly associated with past-year alcohol consequences. No significant associations were observed for alcohol consumption. While the cross-sectional study design does not allow one to ascertain causative associations between PTSD factors and alcohol consumption and consequences, results generally align with the self-medication hypothesis, as PTSD factors reflecting internalizing were most strongly related to alcohol-related consequences. These results underscore the importance of assessing for alcohol use problems in veterans who score highly on PTSD symptoms reflecting internalizing symptomatology. Copyright © 2017 Elsevier Ltd.

Branched five carbon (C5) alcohols are attractive targets for microbial production due to their desirable fuel properties and importance as platform chemicals. In this study, we engineered a heterologous isoprenoid pathway in E. coli for the high-yield production of 3-methyl-3-buten-1-ol, 3-methyl-2-buten-1-ol, and 3-methyl-1-butanol, three C5 alcohols that serve as potential biofuels. We first constructed a pathway for 3-methyl-3-buten-1-ol, where metabolite profiling identified NudB, a promiscuous phosphatase, as a likely pathway bottleneck. We achieved a 60% increase in the yield of 3-methyl-3-buten-1-ol by engineering the Shine-Dalgarno sequence of nudB, which increased protein levels by 9-fold and reduced isopentenyl diphosphate (IPP) accumulation by 4-fold. To further optimize the pathway, we adjusted mevalonate kinase (MK) expression and investigated MK enzymes from alternative microbes such as Methanosarcina mazei. Next, we expressed a fusion protein of IPP isomerase and the phosphatase (Idi1~NudB) along with a reductase (NemA) to diversify production to 3-methyl-2-buten-1-ol and 3-methyl-1-butanol. Finally, we used an oleyl alcohol overlay to improve alcohol recovery, achieving final titers of 2.23 g/L of 3-methyl-3-buten-1-ol (~70% of pathway-dependent theoretical yield), 150 mg/L of 3-methyl-2-buten-1-ol, and 300 mg/L of 3-methyl-1-butanol.

Alcohol consumption in our society is a known, and a widely discussed problem, due to the proven negative impact of excessive usage of spirits on health. Aim of the study was to evaluate the rate of consumption, and risk of an alcoholic disease among Polish students. Study was carried out using an authors' own questionnaire, made of a queries about amount and frequency of alcohol consumption, risky behaviors and knowledge about alcoholism. Research was conducted through community portals (f.e. facebook.com), and within 3 weeks time (from a 10(th) of January to 31(st) of January 2013) 1300 students from different Polish universities participated in it. Out of them, after removal of inadequate questionnaires, group of 1259 students (822 females, 437 males) was selected for further analysis. Average age equaled to 21.5, with the maximum of 27 and minimum of 18 years. For the statistical analysis StatSoft "Statistica" 10.0 software was used. The study shows that 95.5% of students use alcohol (mostly beer and vodka) and they tend to overuse it. 28.86% of respondents drank excessively more than 3 times during the month preceding research, 46% of subjects also had an alcoholic palimpsest more than once, 12.7% need an alcohol to enjoy a party and 0.83% of respondents can't control the amount of a one-time alcohol consumption. 3.32% of students may be in the group of a high alcoholism risk. Alcohol consumption is a common problem among Polish students. Most of respondents, mostly males, drink excessively and potentially risky for their health. There is a remarkable group of students endangered with alcohol addiction.

Full Text Available Abstract Background The Provincial Alcohol Index (PAI is one of the efforts to develop a composite measurement to operationalize the situation of alcohol consumption and related risk behaviors. The index offers a means for national and subnational alcohol control committees to address alcohol-related problems in their responsible jurisdiction areas. The objective of this study is to assess the relationship between PAI scores and alcohol-related problems using Thailand as an example. Methods Cross-sectional analyses of PAI scores based on the 2007 National Cigarette Smoking and Alcohol Drinking Behavior Survey (CSAD and the National Statistical Office data were conducted. CSAD data were collected from 168,285 Thai residents aged 15 years and above in 76 provinces of Thailand (population range 180,787 to 5,716,248. The PAI scores were generated using three different methods based on five indicators: 1 prevalence of adult (≥15 years drinkers, 2 prevalence of underage drinkers, 3 proportion of regular drinkers, 4 proportion of binge drinkers and 5 proportion of drink-drivers. Alcohol-related injuries and violent events together with provincial level covariates (age, gender, income and region were assessed. Correlational and linear regression analyses were performed to examine the relationship between PAI scores and alcohol-related problems. Results The PAI scores generated from the three methods were significantly correlated with one another (r > 0.7, p < 0.05 and significantly related to alcohol-related problems after adjusting for the provincial level covariates. Based on the normalized method, PAI scores had a significant and positive relationship with prevalence of alcohol-related injuries (beta = 562 cases per million population, p = 0.027 and violence (beta = 451 events per million population, p = 0.013. PAI scores were highest in the north and lowest in the south of the country. Conclusions The findings of this

We have recently reported that alcohol attenuates cocaine place preferences. Although the basis for this effect is unknown, alcohol may attenuate cocaine reward by potentiating its aversive effects. To examine this possibility, these experiments assessed the effects of alcohol on cocaine-induced taste aversions under conditions similar to those that resulted in attenuated place preferences. Specifically, Experiments 1 and 2 assessed the effects of alcohol (0.5 g/kg) on taste aversions induced by 20, 30 and 40 mg/kg cocaine. Experiment 3 examined the role of intertrial interval in the effects of alcohol (0.5 g/kg) on cocaine (30 mg/kg) taste aversions. In Experiments 1 and 2, cocaine was effective at conditioning aversions. Alcohol produced no measurable effect. Combining cocaine and alcohol produced no greater aversion than cocaine alone (and, in fact, weakened aversions at the lowest dose of cocaine). In Experiment 3, varying the intertrial interval from 3 days (as in the case of Experiments 1 and 2) to 1 day (a procedure identical to that in which alcohol attenuated cocaine place preferences) resulted in significant alcohol- and cocaine-induced taste aversions. Nonetheless, alcohol remained ineffective in potentiating cocaine aversions. Thus, under these conditions alcohol does not potentiate cocaine's aversiveness. These results were discussed in terms of their implication for the effects of alcohol on cocaine-induced place preferences. Further, the effects of alcohol on place preferences conditioned by cocaine were discussed in relation to other assessments of the effects of alcohol on the affective properties of cocaine and the implications of these interactions for alcohol and cocaine co-use.

Full Text Available Alcohol use disorders (AUDs may be associated with several psychological and affective disorders. It is controversial, however, if these symptoms are a cause or rather a consequence of alcohol dependence. There are few data testing simultaneously psychosocial and affective disorders before and after a period of alcohol abstinence. The aim of this study was to perform multiple psychometric evaluations in alcohol-dependent patients before and after 12 weeks of abstinence. Twenty-five alcohol-dependent patients were included in the study. The following psychometric tests were administered at baseline (T0 and after 12 weeks (T1: Addiction Severity Index (ASI, Brief Psychiatric Rating Scale (BPRS, Social Behaviour Scale (SBS, Sheehan Disability Scale (DISS, Aggression Questionnaire (AQ. At T1, 16 (64% patients were abstinent, 5 (20% patients dropped out and 4 (16% patients relapsed. Compared to T0, patients totally abstinent at T1 showed a significant reduction of the scores related to BPRS, BPRS-E and its subscales (except BPRS 5, ASI 1, ASI 2, ASI 3, ASI 6, ASI 7, BSM, AQ, DISS 1, DISS 2, DISS 3 (p<0.05. No significant changes in ASI 4, ASI 5, DISS 4 and DISS 5, BPRS 5 scores were found at T1 compared to T0. The present study indicates that total alcohol abstinence improves psychometric features, such as alcohol addiction severity, psychiatric rating, social behaviour, aggressiveness, and disability. Larger controlled studies are needed to confirm these findings.

The synthesis of the aroma chemical cinnamyl alcohol (CMO) by means of enzymatic reduction of cinnamaldehyde (CMA) was investigated using NADH-dependent alcohol dehydrogenase from Bacillus stearothermophilus both as an isolated enzyme, and in recombinant Escherichia coli whole cells. The influence of parameters such as reaction time and cofactor, substrate, co-substrate 2-propanol and biocatalyst concentrations on the bioreduction reaction was investigated and an efficient and sustainable one-phase system developed. The reduction of CMA (0.5 g/L, 3.8 mmol/L) by the isolated enzyme occurred in 3 h at 50 °C with 97% conversion, and yielded high purity CMO (≥98%) with a yield of 88% and a productivity of 50 g/genzyme. The reduction of 12.5 g/L (94 mmol/L) CMA by whole cells in 6 h, at 37 °C and no requirement of external cofactor occurred with 97% conversion, 82% yield of 98% pure alcohol and a productivity of 34 mg/gwet cell weight. The results demonstrate the microbial system as a practical and efficient method for larger-scale synthesis of CMO.

Information on the stimulatory and inhibitory effects of cuticular alcohols on growth and virulence of insecticidal fungi is unavailable. Therefore, we set out to describe the content of cuticular and internal alcohols in the body of housefly larvae, pupae, males and females. The total cuticular alcohols in larvae, males and females of Musca domestica were detected in comparable amounts (4.59, 3.95 and 4.03 μg g(-1) insect body, respectively), but occurred in smaller quantities in pupae (2.16 μg g(-1)). The major free alcohol in M. domestica larvae was C(12:0) (70.4%). Internal alcohols of M. domestica larvae were not found. Among cuticular pupae alcohols, C(12:0) (31.0%) was the most abundant. In the internal lipids of pupae, only five alcohols were identified in trace amounts. The most abundant alcohol in males was C(24:0) (57.5%). The percentage content of cuticular C(24:0) in males and females (57.5 and 36.5%, respectively) was significantly higher than that of cuticular lipids in larvae and pupae (0.9 and 5.6%, respectively). Only two alcohols were present in the internal lipids of males in trace amounts (C(18:0) and C(20:0)). The most abundant cuticular alcohols in females were C(24:0) (36.5%) and C(12:0) (26.8%); only two alcohols (C(18:0) and C(20:0)) were detected in comparable amounts in internal lipids (3.61±0.32 and 5.01±0.42 μg g(-1), respectively). For isolated alcohols, antimicrobial activity against 10 reference strains of bacteria and fungi was determined. Individual alcohols showed approximately equal activity against fungal strains. C(14:0) was effective against gram-positive bacteria, whereas gram-negative bacteria were resistant to all tested alcohols. Mixtures of alcohols found in cuticular lipids of larvae, pupae, males and females of M. domestica generally presented higher antimicrobial activity than individual alcohols. In contrast, crude extracts containing both cuticular and internal lipids showed no antifungal activity against the

The increased susceptibility for developing alcohol dependence seen in offspring from families with alcohol dependence may be related to structural and functional differences in brain circuits that influence emotional processing. Early childhood environment, genetic variation in the serotonin transporter-linked polymorphic region (5-HTTLPR) of the SLCA4 gene and allelic variation in the Brain Derived Neurotrophic Factor (BDNF) gene have each been reported to be related to volumetric differences in the temporal lobe especially the amygdala. Magnetic resonance imaging was used to obtain amygdala volumes for 129 adolescent/young adult individuals who were either High-Risk (HR) offspring from families with multiple cases of alcohol dependence (N=71) or Low-Risk (LR) controls (N=58). Childhood family environment was measured prospectively using age-appropriate versions of the Family Environment Scale during a longitudinal follow-up study. The subjects were genotyped for Brain-Derived Neurotrophic Factor (BDNF) Val66Met and the serotonin transporter polymorphism (5-HTTLPR). Two family environment scale scores (Cohesion and Conflict), genotypic variation, and their interaction were tested for their association with amygdala volumes. Personal and prenatal exposure to alcohol and drugs were considered in statistical analyses in order to more accurately determine the effects of familial risk group differences. Amygdala volume was reduced in offspring from families with multiple alcohol dependent members in comparison to offspring from control families. High-Risk offspring who were carriers of the S variant of the 5-HTTLPR polymorphism had reduced amygdala volume in comparison to those with an LL genotype. Larger amygdala volume was associated with greater family cohesion but only in Low-Risk control offspring. Familial risk for alcohol dependence is an important predictor of amygdala volume even when removing cases with significant personal exposure and covarying for

Chavez, Laura J; Williams, Emily C; Lapham, Gwen T; Rubinsky, Anna D; Kivlahan, Daniel R; Bradley, Katharine A

2016-05-01

Brief alcohol interventions are recommended for primary care patients who screen positive for alcohol misuse, but implementation is challenging. The U.S. Veterans Health Administration (Veterans Affairs [VA]) implemented brief interventions for patients with alcohol misuse in 2008, and rates of brief interventions documented in the electronic medical record increased from 24% to 78% (2008-2011). This study examined whether an independent measure of brief interventions-patient-reported alcohol-related advice-also increased among VA outpatients who screened positive for alcohol misuse on a mailed survey. This retrospective cross-sectional study included VA outpatient respondents to the VA's Survey of Healthcare Experiences of Patients (SHEP; 2007-2011) who reported past-year alcohol use and answered a question about alcohol-related advice. Alcohol-related advice was defined as a report of past-year advice from a VA clinician to abstain from or reduce drinking. The adjusted prevalence of alcoholrelated advice among patients who screened positive for alcohol misuse (SHEP AUDIT-C ≥ 5) was estimated for each year. Among patients with alcohol misuse (n = 61,843), the adjusted prevalence of alcohol-related advice increased from 40.4% (95% CI [39.3%, 41.5%]) in 2007 to 55.5% (95% CI [53.3%, 57.8%]) in 2011. Rates of alcoholrelated advice increased significantly each year except the last. The VA's efforts to implement brief interventions were associated with increased patient-reported alcohol-related advice over time, with a majority of patients with alcohol misuse reporting its receipt. Other systems considering similar approaches to implementation may benefit from collecting patient-reported measures of brief interventions for an additional perspective on implementation.

The omega-3 fatty acid eicosapentaenoic acid is required for normal alcohol response behaviors in C. elegans.

Directory of Open Access Journals (Sweden)

Richard C Raabe

Full Text Available Alcohol addiction is a widespread societal problem, for which there are few treatments. There are significant genetic and environmental influences on abuse liability, and understanding these factors will be important for the identification of susceptible individuals and the development of effective pharmacotherapies. In humans, the level of response to alcohol is strongly predictive of subsequent alcohol abuse. Level of response is a combination of counteracting responses to alcohol, the level of sensitivity to the drug and the degree to which tolerance develops during the drug exposure, called acute functional tolerance. We use the simple and well-characterized nervous system of Caenorhabditis elegans to model the acute behavioral effects of ethanol to identify genetic and environmental factors that influence level of response to ethanol. Given the strong molecular conservation between the neurobiological machinery of worms and humans, cellular-level effects of ethanol are likely to be conserved. Increasingly, variation in long-chain polyunsaturated fatty acid levels has been implicated in complex neurobiological phenotypes in humans, and we recently found that fatty acid levels modify ethanol responses in worms. Here, we report that 1 eicosapentaenoic acid, an omega-3 polyunsaturated fatty acid, is required for the development of acute functional tolerance, 2 dietary supplementation of eicosapentaenoic acid is sufficient for acute tolerance, and 3 dietary eicosapentaenoic acid can alter the wild-type response to ethanol. These results suggest that genetic variation influencing long-chain polyunsaturated fatty acid levels may be important abuse liability loci, and that dietary polyunsaturated fatty acids may be an important environmental modulator of the behavioral response to ethanol.

Therapeutic potential of mGluR5 targeting in Alzheimer's disease

Directory of Open Access Journals (Sweden)

Anil eKumar

2015-06-01

Full Text Available Decades of research dedicated towards Alzheimer's disease (AD has culminated in much of the current understanding of the neurodegeneration associated with disease. However, delineating the pathophysiology and finding a possible cure for the disease is still wanting. This is in part due to the lack of knowledge pertaining to the connecting link between neurodegenerative and neuroinflammatory pathways. Consequently, the inefficacy and ill-effects of the drugs currently available for AD encourage the need for alternative and safe therapeutic intervention. In this review we highlight the potential of mGluR5, a metabotropic glutamatergic receptor, in understanding the mechanism underlying the neuronal death and neuroinflammation in AD. We also discuss the role of mGlu5 receptor in mediating the neuron-glia interaction in the disease. Finally, we discuss the potential of mGluR5 as target for treating AD.

A waxy cuticle that serves as a protective barrier against non-stomatal water loss and environmental damage coats the aerial surfaces of land plants. It comprises a cutin polymer matrix and waxes. Cuticular waxes are complex mixtures of very long chain fatty acids (VLCFAs) and their derivatives. Results show that primary alcohols are the major components of bread wheat (Triticum aestivum L.) leaf blade cuticular waxes. Here, the characterization of TaFAR5 from wheat cv Xinong 2718, which is allelic to TAA1b, an anther-specific gene, is reported. Evidence is presented for a new function for TaFAR5 in the biosynthesis of primary alcohols of leaf blade cuticular wax in wheat. Expression of TaFAR5 cDNA in yeast (Saccharomyces cerevisiae) led to production of C22:0 primary alcohol. The transgenic expression of TaFAR5 in tomato (Solanum lycopersicum) cv MicroTom leaves resulted in the accumulation of C26:0, C28:0, and C30:0 primary alcohols. TaFAR5 encodes an alcohol-forming fatty acyl-coenzyme A reductase (FAR). Expression analysis revealed that TaFAR5 was expressed at high levels in the leaf blades, anthers, pistils, and seeds. Fully functional green fluorescent protein-tagged TaFAR5 protein was localized to the endoplasmic reticulum (ER), the site of primary alcohol biosynthesis. SDS-PAGE analysis indicated that the TaFAR5 protein possessed a molecular mass of 58.4kDa, and it was also shown that TaFAR5 transcript levels were regulated in response to drought, cold, and abscisic acid (ABA). Overall, these data suggest that TaFAR5 plays an important role in the synthesis of primary alcohols in wheat leaf blade. © The Author 2014.

1996-07-01

The purpose of the present study was to examine the processes underlying relapse to drinking using objective biological validation of self-reported recent alcohol consumption, using the ratio of 5-hydroxytryptophol to 5-hydroxyindol-3-ylacetic acid (5-HTOL/5-HIAA), a new biological marker to detect single episodes of drinking, in a sample of 38 male alcohol-dependent patients (DSM-III-R) who were assessed prospectively in terms of their clinical symptomatology over a 6-month treatment period. Results showed that nearly all patients obtained positive 5-HTOL/5-HIAA samples during the course of treatment. However, upon closer inspection, results revealed a bimodal distribution for alcohol intake with high and low frequency of consumption episodes. Results showed that high frequency consumers obtained higher ratings of clinical symptoms as measured by the Comprehensive Psychopathological Rating Scale (CPRS) and by the St Göran's Semi-structured Interview (SGSI) compared to low frequency alcohol consumers on symptoms of inner tension, lack of initiative, risk of relapse (as rated by therapists and as rated by patients themselves), dysphoria, negative craving for alcohol, and positive craving for alcohol. The present results provided evidence for the existence of two sub-populations of alcoholics, those who have frequent lapses and those who have low frequency of sporadic lapses. Further, these two sub-populations were shown to differ with respect to overall psychological functioning, and craving for alcohol. In conclusion, the present findings have important treatment implications in that reliable identification of patients' consumption patterns using biological markers would allow for the design of individually tailored treatment needs.

2014-01-01

Graphical abstract: Oxidation of various alcohols is studied in the liquid phase over new composite mixed oxide (V 2 O 5 /OMS-2) catalyst using tert-butyl hydroperoxide (TBHP). The activity of V 2 O 5 /OMS-2 samples was considerably increased with respect to OMS-2 catalyst and these samples are found to be suitable for the selective oxidation of alcohols. - Highlights: • V 2 O 5 /K-OMS-2 with different V/Mn molar ratios prepared by the impregnation method. • Oxidation of alcohols was studied in the liquid phase over V 2 O 5 /K-OMS-2 catalyst. • V 2 O 5 /K-OMS-2 catalyst had excellent activity for alcohol oxidation. • Benzyl alcohol oxidation using excess TBHP followed a pseudo-first order kinetic. • The selected catalyst was reused without significant loss of activity. - Abstract: This work reports the synthesis and characterization of mixed oxide vanadium–manganese V 2 O 5 /K-OMS-2 at various V/Mn molar ratios and prepared by the impregnation method. Characterization of these new composite materials was made by elemental analysis, BET, XRD, FT-IR, SEM and TEM techniques. Results of these analyses showed that vanadium impregnated samples contained mixed phases of cryptomelane and crystalline V 2 O 5 species. Oxidation of various alcohols was studied in the liquid phase over the V 2 O 5 /K-OMS-2 catalyst using tert-butyl hydroperoxide (TBHP) and H 2 O 2 as the oxidant. Activity of the V 2 O 5 /K-OMS-2 samples was increased considerably with respect to K-OMS-2 catalyst due to the interaction of manganese oxide and V 2 O 5 . The kinetic of benzyl alcohol oxidation using excess TBHP over V 2 O 5 /K-OMS-2 catalyst was investigated at different temperatures and a pseudo-first order reaction was determined with respect to benzyl alcohol. The effects of reaction time, oxidant/alcohol molar ratio, reaction temperature, solvents, catalyst recycling potential and leaching were investigated

1979-10-01

A microbial electrode consisting of immobilized microorganisms, a gas permeable Teflon membrane, and an oxygen electrode was prepared for the continuous determination of methyl and ethyl alcohols. Immobilized Trichosporon brassicae was employed for a microbial electrode sensor for ethyl alcohol. When a sample solution containing ethyl alcohol was injected into a microbial electrode system, the current of the electrode decreased markedly with time until a steady state was reached. The response time was within 10 min by the steady state method and within 6 min by the pulse method. A linear relationship was observed between the current decrease and the concentration of ethyl alcohol below 22.5 mg/liter. The current was reproducible within +- 6% of the relative error when a sample solution containing 16.5 mg/liter ethyl alcohol. The standard deviation was 0.5 mg/liter in 40 experiments. The selectivity of the microbial electrode sensor for ethyl alcohol was satisfactory. The microbial electrode sensor was applied to a fermentation broth of yeasts and satisfactory comparative results were obtained (correlation coefficient 0.98). The current output of the microbial electrode sensor was almost constant for more than three weeks and 2100 assays. A microbial electrode sensor using immobilized bacteria for methyl alcohol was also described.

Preclinical work suggests that GET 73 (N-[4-(trifluoromethyl)benzyl]-4-methoxybutyramide), a novel metabotropic glutamate receptor subtype 5 negative allosteric modulator, may represent a novel pharmacological treatment for alcohol use disorder. Two independent experiments evaluated the effect of acutely administered GET 73 (0, 30, and 100 mg/kg, intragastrically) on alcohol-induced hypolocomotion ( n=72) and sedation/hypnosis ( n=36) in rats. In healthy male volunteers ( n=14), an open-label, randomised, crossover study was conducted to compare adverse events and pharmacokinetic parameters, in two experiments in which 300 mg GET 73 was administered, with and without alcohol, once and thrice. In rats, when administered with alcohol-vehicle, 100 mg/kg, but not 30 mg/kg, GET 73 reduced spontaneous locomotor activity. When administered with alcohol, no dose of GET 73 altered either alcohol-induced hypolocomotion or sedation/hypnosis. In humans, both single and thrice 300 mg GET 73 administration were well tolerated, in the presence and absence of alcohol, with no differences in adverse events. There were no significant differences in relative bioavailability between administering 300 mg GET 73 in the presence or absence of alcohol.

Graphene oxide - Polyvinyl alcohol nanocomposite based electrode material for supercapacitors

Science.gov (United States)

Pawar, Pranav Bhagwan; Shukla, Shobha; Saxena, Sumit

2016-07-01

Supercapacitors are high capacitive energy storage devices and find applications where rapid bursts of power are required. Thus materials offering high specific capacitance are of fundamental interest in development of these electrochemical devices. Graphene oxide based nanocomposites are mechanically robust and have interesting electronic properties. These form potential electrode materials efficient for charge storage in supercapacitors. In this perspective, we investigate low cost graphene oxide based nanocomposites as electrode material for supercapacitor. Nanocomposites of graphene oxide and polyvinyl alcohol were synthesized in solution phase by integrating graphene oxide as filler in polyvinyl alcohol matrix. Structural and optical characterizations suggest the formation of graphene oxide and polyvinyl alcohol nanocomposites. These nanocomposites were found to have high specific capacitance, were cyclable, ecofriendly and economical. Our studies suggest that nanocomposites prepared by adding 0.5% wt/wt of graphene oxide in polyvinyl alcohol can be used an efficient electrode material for supercapacitors.

1999-07-01

The importance of implementing comprehensive drug and alcohol policies in the workplace was discussed with particular emphasis on the procedures which are needed to ensure that employers meet due diligence requirements regarding alcoholism and drug abuse. A study of workplace substance abuse issues in Alberta revealed that 80 per cent of the Alberta workforce uses alcohol, 27 per cent use cold medication, and 6.5 per cent use illicit drugs. The impact of drug and alcohol use in the workplace was also reviewed. Under the Canadian human rights legislation an employer cannot terminate an employee for having a medical illness including alcoholism or drug addiction. The issue of drug testing and when to drug screen was also discussed. It was suggested that addressing substance abuse in the workplace through policy procedures and practices can reduce costs related to lost productivity, absenteeism, workers` compensation claims, staff turnover, health benefit premiums and legal liabilities. 3 refs.

Alcohol abuse causes 79,000 deaths stemming from severe organ damage in the United States every year. Clinical manifestations of long-term alcohol abuse on the cardiac muscle include defective contractility with the development of dilated cardiomyopathy and low-output heart failure; which has poor prognosis with less than 25% survival for more than three years. In contrast, low alcohol consumption has been associated with reduced risk of cardiovascular disease, however the mechanism of this phenomenon remains elusive. The aim of this study was to determine the significance of apoptosis as a mediating factor in cardiac function following chronic high alcohol versus low alcohol exposure. Adult rats were provided 5 mM (low alcohol), 100 mM (high alcohol) or pair-fed non-alcohol controls for 4-5 months. The hearts were dissected, sectioned and stained with cresyl violet or immunohistochemically for caspase-3, a putative marker for apoptosis. Cardiomyocytes were isolated to determine the effects of alcohol exposure on cell contraction and relaxation. High alcohol animals displayed a marked thinning of the left ventricular wall combined with elevated caspase-3 activity and decreased contractility. In contrast, low alcohol was associated with increased contractility and decreased apoptosis suggesting an overall protective mechanism induced by low levels of alcohol exposure.

Amide Synthesis from Alcohols and Amines Catalyzed by Ruthenium N-Heterocyclic Carbene Complexes

DEFF Research Database (Denmark)

Dam, Johan Hygum; Osztrovszky, Gyorgyi; Nordstrøm, Lars Ulrik Rubæk

2010-01-01

The direct synthesis of amides from alcohols and amines is described with the simultaneous liberation of dihydrogen. The reaction does not require any stoichiometric additives or hydrogen acceptors and is catalyzed by ruthenium N-heterocyclic carbene complexes. Three different catalyst systems...... are presented that all employ 1,3-diisopropylimidazol-2-ylidene (IiPr) as the carbene ligand. In addition, potassium tert-butoxide and a tricycloalkylphosphine are required for the amidation to proceed. In the first system, the active catalyst is generated in situ from [RuCl2(cod)] (cod = 1,5-cyclooctadiene), 1...... chloride and base. A range of different primary alcohols and amines have been coupled in the presence of the three catalyst systems to afford the corresponding amides in moderate to excellent yields. The best results are obtained with sterically unhindered alcohols and amines. The three catalyst systems do...

To test whether reducing the standard serving size of alcoholic beverages would reduce voluntary alcohol consumption in a laboratory (study 1) and a real-world drinking environment (study 2). Additionally, we modelled the potential public health benefit of reducing the standard serving size of on-trade alcoholic beverages in the United Kingdom. Studies 1 and 2 were cluster-randomized experiments. In the additional study, we used the Sheffield Alcohol Policy Model to estimate the number of deaths and hospital admissions that would be averted per year in the United Kingdom if a policy that reduces alcohol serving sizes in the on-trade was introduced. A semi-naturalistic laboratory (study 1), a bar in Liverpool, UK (study 2). Students and university staff members (study 1: n = 114, mean age = 24.8 years, 74.6% female), residents from local community (study 2: n = 164, mean age = 34.9 years, 57.3% female). In study 1, participants were assigned randomly to receive standard or reduced serving sizes (by 25%) of alcohol during a laboratory drinking session. In study 2, customers at a bar were served alcohol in either standard or reduced serving sizes (by 28.6-33.3%). Outcome measures were units of alcohol consumed within 1 hour (study 1) and up to 3 hours (study 2). Serving size condition was the primary predictor. In study 1, a 25% reduction in alcohol serving size led to a 20.7-22.3% reduction in alcohol consumption. In study 2, a 28.6-33.3% reduction in alcohol serving size led to a 32.4-39.6% reduction in alcohol consumption. Modelling results indicated that decreasing the serving size of on-trade alcoholic beverages by 25% could reduce the number of alcohol-related hospital admissions and deaths per year in the United Kingdom by 4.4-10.5% and 5.6-13.2%, respectively. Reducing the serving size of alcoholic beverages in the United Kingdom appears to lead to a reduction in alcohol consumption within a single drinking occasion. © 2018 The Authors. Addiction

2017-08-02

Excessive mRNA translation downstream of group I metabotropic glutamate receptors (mGlu 1/5 ) is a core pathophysiology of fragile X syndrome (FX); however, the differentially translating mRNAs that contribute to altered neural function are not known. We used translating ribosome affinity purification (TRAP) and RNA-seq to identify mistranslating mRNAs in CA1 pyramidal neurons of the FX mouse model (Fmr1 -/y ) hippocampus, which exhibit exaggerated mGlu 1/5 -induced long-term synaptic depression (LTD). In these neurons, we find that the Chrm4 transcript encoding muscarinic acetylcholine receptor 4 (M 4 ) is excessively translated, and synthesis of M 4 downstream of mGlu 5 activation is mimicked and occluded. Surprisingly, enhancement rather than inhibition of M 4 activity normalizes core phenotypes in the Fmr1 -/y , including excessive protein synthesis, exaggerated mGluR-LTD, and audiogenic seizures. These results suggest that not all excessively translated mRNAs in the Fmr1 -/y brain are detrimental, and some may be candidates for enhancement to correct pathological changes in the FX brain.

Chung, Tammy; Cornelius, Jack; Clark, Duncan; Martin, Christopher

2017-09-01

Proposed International Classification of Diseases, 11th edition (ICD-11), criteria for substance use disorder (SUD) radically simplify the algorithm used to diagnose substance dependence. Major differences in case identification across DSM and ICD impact determinations of treatment need and conceptualizations of substance dependence. This study compared the draft algorithm for ICD-11 SUD against DSM-IV, DSM-5, and ICD-10, for alcohol and cannabis. Adolescents (n = 339, ages 14 to 18) admitted to intensive outpatient addictions treatment completed, as part of a research study, a Structured Clinical Interview for DSM SUDs adapted for use with adolescents and which has been used to assess DSM and ICD SUD diagnoses. Analyses examined prevalence across classification systems, diagnostic concordance, and sources of diagnostic disagreement. Prevalence of any past-year proposed ICD-11 alcohol or cannabis use disorder was significantly lower compared to DSM-IV and DSM-5 (ps DSM-5, and ICD-10 (ps DSM-5 SUD diagnoses showed only moderate concordance. For both alcohol and cannabis, youth typically met criteria for an ICD-11 dependence diagnosis by reporting tolerance and much time spent using or recovering from the substance, rather than symptoms indicating impaired control over use. The proposed ICD-11 dependence algorithm appears to "overdiagnose" dependence on alcohol and cannabis relative to DSM-IV and ICD-10 dependence, and DSM-5 moderate/severe use disorder, generating potential "false-positive" cases of dependence. Among youth who met criteria for proposed ICD-11 dependence, few reported impaired control over substance use, highlighting ongoing issues in the conceptualization and diagnosis of SUD.

Objectives While screening the activity of potential inhibitors of matrix metalloproteinases (MMPs), due to the limited water solubility of some of the compounds, they had to be solubilized in ethanol. When ethanol solvent controls were run, they were found to partially inhibit MMPs. Thus, the purpose of this study was to compare the MMP-inhibitory activity of a series of alcohols. Methods The possible inhibitory activity of a series of alcohols was measured against soluble rhMMP-9 and insoluble matrix-bound endogenous MMPs of dentin in completely demineralized dentin. Increasing concentrations (0.17, 0.86, 1.71 and 4.28 moles/L) of a homologous series of alcohols (i.e. methanol, ethanol, propanols, butanols, pentanols, hexanols, the ethanol ester of methacrylic acid, heptanols and octanol) were compared to ethanediol, and propanediol by regression analysis to calculate the molar concentration required to inhibit MMPs by 50% (i.e. the IC50). Results Using two different MMP models, alcohols were shown to inhibit rhMMP-9 and the endogenous proteases of dentin matrix in a dose-dependent manner. The degree of MMP inhibition by alcohols increased with chain length up to 4 methylene groups. Based on the molar concentration required to inhibit rhMMP-9 fifty percent, 2-hydroxyethylmethacrylate (HEMA), 3-hexanol, 3-heptanol and 1-octanol gave the strongest inhibition. Significance The results indicate that alcohols with 4 methylene groups inhibit MMPs more effectively than methanol or ethanol. MMP inhibition was inversely related to the Hoy's solubility parameter for hydrogen bonding forces of the alcohols (i.e. to their hydrophilicity). PMID:21676453

This paper is based upon the "8th Charles Lieber's Satellite Symposium" organized by Manuela G. Neuman at the Research Society on Alcoholism Annual Meeting, on June 25, 2016 at New Orleans, Louisiana, USA. The integrative symposium investigated different aspects of alcohol-induced liver disease (ALD) as well as non-alcohol-induced liver disease (NAFLD) and possible repair. We revealed the basic aspects of alcohol metabolism that may be responsible for the development of liver disease as well as the factors that determine the amount, frequency and which type of alcohol misuse leads to liver and gastrointestinal diseases. We aimed to (1) describe the immuno-pathology of ALD, (2) examine the role of genetics in the development of alcoholic hepatitis (ASH) and NAFLD, (3) propose diagnostic markers of ASH and non-alcoholic steatohepatitis (NASH), (4) examine age and ethnic differences as well as analyze the validity of some models, (5) develop common research tools and biomarkers to study alcohol-induced effects, 6) examine the role of alcohol in oral health and colon and gastrointestinal cancer and (7) focus on factors that aggravate the severity of organ-damage. The present review includes pre-clinical, translational and clinical research that characterizes ALD and NAFLD. Strong clinical and experimental evidence lead to recognition of the key toxic role of alcohol in the pathogenesis of ALD with simple fatty infiltrations and chronic alcoholic hepatitis with hepatic fibrosis or cirrhosis. These latter stages may also be associated with a number of cellular and histological changes, including the presence of Mallory's hyaline, megamitochondria, or perivenular and perisinusoidal fibrosis. Genetic polymorphisms of ethanol metabolizing enzymes and cytochrome p450 (CYP) 2E1 activation may change the severity of ASH and NASH. Other risk factors such as its co-morbidities with chronic viral hepatitis in the presence or absence of human deficiency virus were discussed

Aldehydes and ketones are important intermediates, especially for the construction of carbon-skeletons. The oxidation of alcohols is so important that a large number of methods and reagents have been reported for this purpose. N-halo reagents are widely used in organic synthesis and as a continuation of our interest in the application of N-halo compounds in organic synthesis, dibromo dimethylhydantoin (DBDMH) and dichloro dimethylhydantoin (DCDMH) were used for the oxidation of alcohols and our ongoing work on development of highly efficient oxidation protocols. We observed the oxidation of secondary alcohols with stoichiometric amounts of DBDMH and DCDMH under solvent-free conditions in the range of temperature 70-80 deg C. (author)

2015-01-01

Maternal alcoholism hinders the normal development of child and threatens his mental and physical health due to three factors: the hereditary transmission of predisposition to alcohol abuse; alcohol consumption during pregnancy; adverse family environment. The children of mothers suffering from alcoholism revealed are characterized by increased risk of depression, anxiety and other mental disorders, including alcohol and substance dependence. The adverse impact of maternal alcoholism (or, to speak more widely, parents' alcoholism) on the child health requires special preventive and treatment programs for both parents and children. Separation from the mother (even if the mother is addicted to alcohol) seriously injures the child, and therefore treatment programs for alcohol abusing women should be focused on the possible continuation of the parental rights of patients.

Alcohol and Suicide: Neurobiological and Clinical Aspects

Directory of Open Access Journals (Sweden)

Leo Sher

2006-01-01

Full Text Available Alcohol, primarily in the form of ethyl alcohol (ethanol, has occupied an important place in the history of humankind for at least 8,000 years. In most Western societies, at least 90% of people consume alcohol at some time during their lives, and 30% or more of drinkers develop alcohol-related problems. Severe alcohol-related life impairment, alcohol dependence (alcoholism, is observed at some time during their lives in about 10% of men and 3—5% of women. An additional 5—10% of each sex develops persistent, but less intense, problems that are diagnosed as alcohol abuse. It this review, neurobiological aspects of suicidal behavior in alcoholism is discussed. In individuals with comorbid depression and alcoholism, greater serotonergic impairment may be associated with higher risk of completed suicide. Dopaminergic dysfunction may play an important role in the pathophysiology of suicidal behavior in alcoholism. Brain damage and neurobehavioral deficits are associated with alcohol use disorders and may contribute to suicidal behavior in persons with alcohol dependence or abuse. Aggression/impulsivity and alcoholism severity affect risk for suicide among individuals with alcoholism. Major depressive episodes and stressful life events particularly, partner-relationship disruptions, may precipitate suicidal behavior in individuals with alcohol use disorders. Alcohol misuse and psychosocial adversity can combine to increase stress on the person, and, thereby, potentially, increase the risk for suicidal behavior. The management of suicidal patients with alcohol use disorders is also discussed. It is to be hoped that the efforts of clinicians will reduce morbidity and mortality associated with alcohol misuse.

2012-08-01

An increasing number of fatal road-accidents have been reported in which ecstasy was found in the blood of drivers. Although, ecstasy is frequently found to have been used in combination with alcohol, studies on the acute effects of ecstasy co-administered with alcohol on driving performance are relatively rare. The present study was designed to establish the extent of driver impairment as a consequence of ecstasy or combined ecstasy and alcohol use as compared to driving under the influence of 0.3‰, 0.5‰ and 0.8‰ alcohol. Furthermore, subjective performance was also assessed. Alcohol and ecstasy mainly influenced automated driving performance such as lateral and speed control. However, small to no effects of the substances were found on more complex driving behaviour. Overall, variance within the different driving measures was high especially when participants were treated with 3.4-methylenedioxy-methamphetamine (MDMA) and alcohol. Furthermore, equivalence testing showed that combined use may lead to impaired driving for some, but not all, drivers. Participants rated their own performance to be slightly worse than normal in both studies. Since driving was actually seriously deteriorated, this was a falsely positive assessment of their condition. The dissociation between subjective perceptions and objective performance decrements are important notions for traffic safety since this may affect a driver's judgement of whether or not it is safe to drive. For example, an intoxicated individual might decide to drive because the feelings of alertness caused by MDMA cloud the impairing effects of other drugs such as alcohol, thereby creating a potentially serious risk for traffic safety.

A rapid and sensitive alcohol oxidase/catalase conductometric biosensor for alcohol determination.

Science.gov (United States)

Hnaien, M; Lagarde, F; Jaffrezic-Renault, N

2010-04-15

A new conductometric biosensor has been developed for the determination of short chain primary aliphatic alcohols. The biosensor assembly was prepared through immobilization of alcohol oxidase from Hansenula sp. and bovine liver catalase in a photoreticulated poly(vinyl alcohol) membrane at the surface of interdigitated microelectrodes. The local conductivity increased rapidly after alcohol addition, reaching steady-state within 10 min. The sensitivity was maximal for methanol (0.394+/-0.004 microS microM(-1), n=5) and decreased by increasing the alcohol chain length. The response was linear up to 75 microM for methanol, 70 microM for ethanol and 65 microM for 1-propanol and limits of detection were 0.5 microM, 1 microM and 3 microM, respectively (S/N=3). No significant loss of the enzyme activities was observed after 3 months of storage at 4 degrees C in a 20mM phosphate buffer solution pH 7.2 (two or three measurements per week). After 4 months, 95% of the initial signal still remained. The biosensor response to ethanol was not significantly affected by acetic, lactic, ascorbic, malic, oxalic, citric, tartaric acids or glucose. The bi-enzymatic sensor was successfully applied to the determination of ethanol in different alcoholic beverages. (c) 2009 Elsevier B.V. All rights reserved.

Excessive alcohol consumption is the third-leading cause of preventable death in the U.S. This systematic review is one in a series exploring effectiveness of interventions to reduce alcohol-related harms. The focus of this review was on studies evaluating the effects of the privatization of alcohol retail sales on excessive alcohol consumption and related harms. Using Community Guide methods for conducting systematic reviews, a systematic search was conducted in multiple databases up to December 2010. Reference lists of acquired articles and review papers were also scanned for additional studies. A total of 17 studies assessed the impact of privatizing retail alcohol sales on the per capita alcohol consumption, a well-established proxy for excessive alcohol consumption; 9 of these studies also examined the effects of privatization on the per capita consumption of alcoholic beverages that were not privatized. One cohort study in Finland assessed the impact of privatizing the sales of medium-strength beer (MSB) on self-reported alcohol consumption. One study in Sweden assessed the impact of re-monopolizing the sale of MSB on alcohol-related harms. Across the 17 studies, there was a 44.4% median increase in the per capita sales of privatized beverages in locations that privatized retail alcohol sales (interquartile interval: 4.5% to 122.5%). During the same time period, sales of nonprivatized alcoholic beverages decreased by a median of 2.2% (interquartile interval: -6.6% to -0.1%). Privatizing the sale of MSB in Finland was associated with a mean increase in alcohol consumption of 1.7 liters of pure alcohol per person per year. Re-monopolization of the sale of MSB in Sweden was associated with a general reduction in alcohol-related harms. According to Community Guide rules of evidence, there is strong evidence that privatization of retail alcohol sales leads to increases in excessive alcohol consumption. Published by Elsevier Inc.

Mohammad Ghoreishi,

2010-01-01

Full Text Available Purpose: To compare the outcomes and complications of alcohol-assisted versus mechanical corneal epithelial debridement for photorefractive keratectomy (PRK. Methods: This randomized controlled trial included 1,250 eyes of 625 patients undergoing PRK for correction of myopia and myopic astigmatism. Each patient was randomly assigned to alcohol-assisted or mechanical epithelial removal. Results: A total of 658 eyes underwent alcohol-assisted epithelial removal while the epithelium was removed mechanically in 592 eyes. Mean spherical equivalent was ‑4.37}2.3 D in the alcohol group and ‑3.8}1.3 D in the mechanical group (P = 0.78. There was no significant difference in postoperative pain between the study groups (P = 0.22. Uncorrected visual acuity ≥ 20/20 and ≥ 20/40 was achieved in 90.9% versus 93.4% (P = 0.08, and 98.9% versus 99.5% (P = 0.36 of eyes in the alcohol and mechanical groups, respectively. Final refractive error within 1D of emmetropia was achieved in 90% versus 92.2% of eyes in the alcohol and mechanical groups, respectively (P = 0.23. Alcohol-assisted debridement required less time than mechanical debridement (96±18 vs. 118±26 seconds, P=0.035. There was no significant difference between the two groups in terms of early and late postoperative complications. Conclusion: Alcohol-assisted and mechanical epithelium removal are comparable in terms of efficacy and side effects. The method of epithelial debridement in PRK may be left to the surgeon′s choice.

One-pot synthesis of 2,5-dihydropyrroles from terminal alkynes, azides, and propargylic alcohols by relay actions of copper, rhodium, and gold.

Relay actions of copper, rhodium, and gold formulate a one-pot multistep pathway, which directly gives 2,5-dihydropyrroles starting from terminal alkynes, sulfonyl azides, and propargylic alcohols. Initially, copper-catalyzed 1,3-dipolar cycloaddition of terminal alkynes with sulfonyl azides affords 1-sulfonyl-1,2,3-triazoles, which then react with propargylic alcohols under the catalysis of rhodium. The resulting alkenyl propargyl ethers subsequently undergo the thermal Claisen rearrangement to give α-allenyl-α-amino ketones. Finally, a gold catalyst prompts 5-endo cyclization to produce 2,5-dihydropyrroles. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Alcohol Use Disorders in Argentinian Girls and Women 12 Months Before Delivery: Comparison of DSM-IV, DSM-5, and ICD-10 Diagnostic Criteria.

Science.gov (United States)

López, Mariana B; Conde, Karina; Cremonte, Mariana

The evidence of important problems related to prenatal alcohol exposure has faced researchers with the problem of understanding and screening alcohol use in this population. Although any alcohol use should be considered risky during pregnancy, identifying alcohol-drinking problems (ADPs) could be especially important because women with ADPs could not benefit from a simple advice of abstinence and because their offsprings are subjected to a higher risk of problems related with prenatal alcohol exposure. In this context, we aim to study the prevalence and characteristics of ADPs in pregnant women, evaluating the performance of different diagnostic systems in this population. The aims of the study were to describe the prevalence of ADPs obtained with the criteria of the Diagnostic and Statistical Manual of Mental Disorders in its fourth (DSM-IV) and fifth edition (DSM-5), and the International Classification of Diseases (ICD)-10, in Argentinean females aged 13 to 44 years, 12 months before delivery; to evaluate the level of agreement between these classification systems; and to analyze the performance of each diagnosis criterion in this population. Data were collected through personal interviews of a probability sample of puerperal women (N = 641) in the city of Santa Fe (Argentina), between October 2010 and February 2011. Diagnoses compatible with DSM-IV, DSM-5, and ICD-10 were obtained through the Composite International Diagnostic Interview. Agreement among diagnostic systems was measured through Cohen kappa. Diagnosis criteria performance were analyzed considering their prevalence and discriminating ability (D value). Total ADP prevalence was 6.4% for DSM-IV (4.2% abuse and 2.2% dependence), 8.1% for DSM-5 (6.4% mild, 0.8% moderate, and 0.9% severe alcohol use disorder), and 14.1% for the ICD-10 (11.9% harmful use and 2.2% dependence). DSM-5 modifications improved agreement between DSM and ICD. The least prevalent and worst discriminating ability diagnostic

Alcohol is popular in Western culture, supported by a perception that modest intake is cardioprotective. However, excessive drinking has detrimental implications for cardiovascular disease. Atrial fibrillation (AF) following an alcohol binge or the "holiday heart syndrome" is well characterized. However, more modest levels of alcohol intake on a regular basis may also increase the risk of AF. The pathophysiological mechanisms responsible for the relationship between alcohol and AF may include direct toxicity and alcohol's contribution to obesity, sleep-disordered breathing, and hypertension. We aim to provide a comprehensive review of the epidemiology and pathophysiology by which alcohol may be responsible for AF and determine whether alcohol abstinence is required for patients with AF.

Full Text Available Methanol is a cheap and potent adulterant of illicit liquors. Hemodialysis (HD is the best method to rapidly remove both toxic acid metabolites and parent alcohols, and it plays a fundamental role in treating severely poisoned patients. This retrospective study was carried out on 91 patients with detectable serum methanol levels who underwent HD. Because toxic alcohol levels were not immediately available, the initial diagnosis and treatment was based on clinical history with evidence of toxic alcohol intake, presence of high anion metabolic acidosis and/or end organ damage. Patients received bicarbonate, ethanol, according to clinical features and blood gases. Patients underwent HD in the setting of known methanol ingestion with high anion gap metabolic acidosis, or evidence of end-organ damage, regardless of methanol level. HD prescription included large surface area dialyzer (≥1.5 m2, blood flow rate of 250-350 mL/min and dialysate flow rate of 500 mL/min for 4-6 h. Between 9 and 11 July 2009, 91 males with mean age 40 ± 8.5 years underwent HD, and 13 patients required a second HD session. Patients consumed 100-500 mL illicit liquors, and symptoms appeared six and 60 h later. Clinical features were gastro-intestinal symptoms (83.5%, visual disturbances (60.4%, central nervous system symptoms (59.3% and dyspnea (43.9%. Before HD, mean pH was 7.11 ± 0.04 (range 6.70- 7.33 and mean bicarbonate levels were 8.5 ± 4.9 mmol/L (range 2-18. Three patients died due to methanol intoxication. Mortality was associated with severe metabolic acidosis (pH ≤ 6.90, ventilator requirement and coma/seizure on admission (P < 0.001. Timely HD, bicarbonate, ethanol and supportive therapy can be life-saving in methanol intoxication.

Full Text Available Introduction: Epidemiologic researches about psychoactive substance use have shown an up-and-coming situation to abusive consumption of alcohol in adolescent and young-adult groups. This consumption over come the knowledge about damage caused by abusive of these substances, especially for the population part who is in the “top of life experiences”; the university students. Aim: To estimate the prevalence of the alcoholic ingestion and alcohol abuse in university students at Jequié-BA, and to verify the association between the alcoholic ingestion and alcohol abuse with the gender, race, smoking and graduation area. Methods: Prevalence study with probabilistic randomized sample (n = 129 of a population of 3,644 university students, registered in three universities. It was used a Questionnaire contends socio-demographic data, asking for the alcoholic ingestion and test CAGE to abuse. Results: It has been found prevalence of 63.6% to alcohol ingestion, 21.7% of high risk in abuse, and 8.5% of alcohol abuse. Although they have not been gotten association statistics between these variable and gender, race, graduation area and smoking; the data had demonstrated highest rates of alcohol abuse, and high risk in developing in students of masculine gender, medium brown race, who attend a graduation course in the health area. Those who have used of the tobacco had presented percentile greater of high risk in becoming alcohol consumer abusive. Conclusions: Intent for data found, as much alcohol ingestion as abuse, since they reflect the necessity of prevention politics to the alcoholic abusive ingestion in this population

Alcohol advertising and youth.

Saffer, Henry

2002-03-01

The question addressed in this review is whether aggregate alcohol advertising increases alcohol consumption among college students. Both the level of alcohol-related problems on college campuses and the level of alcohol advertising are high. Some researchers have concluded that the cultural myths and symbols used in alcohol advertisements have powerful meanings for college students and affect intentions to drink. There is, however, very little empirical evidence that alcohol advertising has any effect on actual alcohol consumption. The methods used in this review include a theoretical framework for evaluating the effects of advertising. This theory suggests that the marginal effect of advertising diminishes at high levels of advertising. Many prior empirical studies measured the effect of advertising at high levels of advertising and found no effect. Those studies that measure advertising at lower, more disaggregated levels have found an effect on consumption. The results of this review suggest that advertising does increase consumption. However, advertising cannot be reduced with limited bans, which are likely to result in substitution to other available media. Comprehensive bans on all forms of advertising and promotion can eliminate options for substitution and be potentially more effective in reducing consumption. In addition, there is an increasing body of literature that suggests that alcohol counteradvertising is effective in reducing the alcohol consumption of teenagers and young adults. These findings indicate that increased counteradvertising, rather than new advertising bans, appears to be the better choice for public policy. It is doubtful that the comprehensive advertising bans required to reduce advertising would ever receive much public support. New limited bans on alcohol advertising might also result in less alcohol counteradvertising. An important topic for future research is to identify the counteradvertising themes that are most effective with

We evaluated the brain lesions of patients with chronic alcoholism in comparison with age-and sex-matched controls by MR imaging. T1-weighted sagittal and axial images and T2-weighted axial images were obtained with a 0.5 T superconducting MR unit. Various brain measurements were then performed, and the presence of regions of abnormal signal intensity was also compared between the two groups. The brain measurements revealed significant cerebral atrophy as well as significant cerebellar atrophy in the alcoholic group. These changes were more prominent in patients in their fifties and sixties than in those aged in the thirties and forties. Focal hypointense lesions were observed in 20.6% of the alcoholics and in 5% of the controls, while focal hyperintense lesions were observed in 61.8% of the alcoholics and in 20% of the controls. The severity of the MR findings correlated well with the age of the patients. These observations suggest that alcohol is an important promotor of brain aging. (orig.).

The calories in alcoholic beverages consumed by alcoholics are a major energy source and a strong modifier of their body weight. Genetic polymorphisms of alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) affect susceptibility to alcoholism and may affect body weight via gene-associated differences in fuel utilization in alcoholics. We evaluated associations between ADH1B/ALDH2 genotypes and the body weight and body mass index (BMI) of 1,301 Japanese alcoholic men at the time of their first visit to an addiction center. Median (25th to 75th) caloric intake in the form of alcoholic beverages was 864 (588 to 1,176) kcal/d. Age-adjusted caloric intake did not differ according to ADH1B/ALDH2 genotypes. The body weight and BMI values showed that the ADH1B*2/*2 and *1/*2 carriers (n = 939) were significantly leaner than the ADH1B*1/*1 carriers (n = 362) irrespective of age, drinking, smoking, and dietary habits. The age-adjusted body weight values of the ADH1B*2/*2, ADH1B*1/*2, and ADH1B*1/*1 carriers were 58.4 ± 0.4, 58.7 ± 0.5, and 63.6 ± 0.5 kg, respectively (ADH1B*2 vs. ADH1B*1/*1 carriers, p strong determinant of body weight in the alcoholics. The more rapid EtOH elimination associated with the ADH1B*2 allele may result in less efficient utilization of EtOH as an energy source in alcoholics.

The highest consumption levels of alcohol are found in the developed world, mostly the Northern Hemisphere. After a slight decrease at the beginning of the 1990s, alcohol use in the European Region increased with an average adult per capita consumption amounting to 12.5 litres of pure alcohol per capita for the year 2009. In France, adult consumption was 12.7 litres of pure alcohol per capita for the year 2009, and it is estimated that 1.5 to 2 million of adults are alcohol-dependent (4-5% of the adult population) and 5 million are excessive drinkers. The harmful use of alcohol is one of the world's leading health risks. Alcohol is the direct cause of more than 30 diseases and a causal factor in more than 60 major types of diseases and injuries, resulting in approximately 2.5 million deaths each year. Approximately 4% of all deaths worldwide and 4.5% (7.4% for men and 1.4% for women) of the global burden of disease and injury are attributable to alcohol. In 2004 in the EU, 15.2% of all disability-adjusted life years (DALYs) in men and 3.9% of all DALYs in women were lost due to alcohol. While the impact of alcohol consumption and dependence on mortality and disease is substantial, there are also many psychosocial consequences, including violence, family problems, child neglect and abuse, absenteeism and lost productivity in the workplace. This means that alcohol consumption and dependence have sizable impacts on many people other than the drinker. These effects add up to a staggering number of alcohol-attributable social costs, which can be estimated at € 155.8 billion a year in Europe. Despite all these consequences, many individuals with alcohol use disorders remain untreated although effective treatments exist. From 37 community-based psychiatric epidemiology studies that used standardized diagnostic instruments and included data on the percentage of individuals receiving care for alcohol abuse or dependence, the median rate of untreated cases of these

Negative allosteric modulation (NAM) of metabotropic glutamate receptor subtype 5 (mGlu5) represents a therapeutic strategy for the treatment of childhood developmental disorders, such as fragile X syndrome and autism. VU0409106 emerged as a lead compound within a biaryl ether series, displaying potent and selective inhibition of mGlu5. Despite its high clearance and short half-life, VU0409106 demonstrated efficacy in rodent models of anxiety after extravascular administration. However, lack of a consistent correlation in rat between in vitro hepatic clearance and in vivo plasma clearance for the biaryl ether series prompted an investigation into the biotransformation of VU0409106 using hepatic subcellular fractions. An in vitro appraisal in rat, monkey, and human liver S9 fractions indicated that the principal pathway was NADPH-independent oxidation to metabolite M1 (+16 Da). Both raloxifene (aldehyde oxidase inhibitor) and allopurinol (xanthine oxidase inhibitor) attenuated the formation of M1, thus implicating the contribution of both molybdenum hydroxylases in the biotransformation of VU0409106. The use of 18O-labeled water in the S9 experiments confirmed the hydroxylase mechanism proposed, because 18O was incorporated into M1 (+18 Da) as well as in a secondary metabolite (M2; +36 Da), the formation of which was exclusively xanthine oxidase-mediated. This unusual dual and sequential hydroxylase metabolism was confirmed in liver S9 and hepatocytes of multiple species and correlated with in vivo data because M1 and M2 were the principal metabolites detected in rats administered VU0409106. An in vitro-in vivo correlation of predicted hepatic and plasma clearance was subsequently established for VU0409106 in rats and nonhuman primates. PMID:22711749

Aims To assess the immediate effect of alcohol promoting and alcohol warning advertisements on implicit and explicit attitudes towards alcohol and on alcohol seeking behaviour. Methods We conducted a between-participants online experiment in which participants were randomly assigned to view one of three sets of advertisements: (a) alcohol promoting, (b) alcohol warning, or (c) unrelated to alcohol. A total of 373 participants (59.5% female) aged 18–40 (M = 28.03) living in the UK were recruited online through a research agency. Positive and negative implicit attitudes and explicit attitudes towards alcohol were assessed before and after advertisements were viewed. Alcohol seeking behaviour was measured by participants' choice of either an alcohol-related or non-alcohol-related voucher offered ostensibly as a reward for participation. Self-reported past week alcohol consumption was also recorded. Results There were no main effects on any of the outcome measures. In heavier drinkers, viewing alcohol promoting advertisements increased positive implicit attitudes (standardized beta = 0.15, P = 0.04) and decreased negative implicit attitudes (standardized beta = −0.17, P = 0.02). In heavier drinkers, viewing alcohol warning advertisements decreased negative implicit attitudes (standardized beta = −0.19, P = 0.01). Conclusions Viewing alcohol promoting advertisements has a cognitive impact on heavier drinkers, increasing positive and reducing negative implicit attitudes towards alcohol. Viewing alcohol warning advertisements reduces negative implicit attitudes towards alcohol in heavier drinkers, suggestive of a reactance effect. PMID:26391367

Towards a global alcohol policy: alcohol, public health and the role of WHO.

In 1983 the World Health Assembly declared alcohol-related problems to be among the world's major health concerns. Since then, alcohol consumption has risen in developing countries, where it takes a heavy toll. Alcohol-related problems are at epidemic levels in the successor states of the Soviet Union and are responsible for 3.5% of disability-adjusted life years (DALYs) lost globally. Substantial evidence exists of the relationship between the levels and patterns of alcohol consumption on the one hand and the incidence of alcohol-related problems on the other. Over the past 20 years, research has demonstrated the effectiveness of public policies involving, for example, taxation and restrictions on alcohol availability, in reducing alcohol-related problems. In the wake of rapid economic globalization, many of these policies at national and subnational levels have been eroded, often with the support of international financial and development organizations. Development agencies and international trade agreements have treated alcohol as a normal commodity, overlooking the adverse consequences of its consumption on productivity and health. WHO is in a strong position to take the lead in developing a global alcohol policy aimed at reducing alcohol-related problems, providing scientific and statistical support, capacity-building, disseminating effective strategies and collaborating with other international organizations. Such leadership can play a significant part in diminishing the health and social problems associated with alcohol use. PMID:10885168

College is often a time of alcohol use initiation and displayed Facebook alcohol references. The purpose of this longitudinal study was to determine associations between initial references to alcohol on social media and college students' self-reported recent drinking, binge drinking, and excessive drinking. First-year students from two U.S. public universities were randomly selected from registrar lists for recruitment. Data collection included 2 years of monthly Facebook evaluation. When an initial displayed Facebook alcohol reference was identified, these "New Alcohol Displayers" were contacted for phone interviews. Phone interviews used the validated timeline followback method to evaluate recent alcohol use, binge episodes, and excessive drinking. Analyses included calculation of positive predictive value and Poisson regression. A total of 338 participants were enrolled; 56.1% participants were female, 74.8% were Caucasian, and 58.8% were from the Midwestern University. A total of 167 (49.4%) participants became new alcohol displayers during the first 2 years of college. Among new alcohol displayers, 78.5% reported past 28-day alcohol use. Among new alcohol displayers who reported recent alcohol use, 84.9% reported at least one binge episode. Posting an initial Facebook alcohol reference as a profile picture or cover photo was positively associated with excessive drinking (risk ratio = 2.34; 95% confidence interval, 1.54-3.58). Findings suggest positive associations between references to alcohol on social media and self-reported recent alcohol use. Location of initial reference as a profile picture or cover photo was associated with problematic drinking and may suggest that a student would benefit from clinical investigation or resources.

To investigate the current purchasing behaviours of a group of dependent drinkers and their potential response to future increases in the price of alcohol. 115 clients undergoing medical detoxification completed an anonymous survey about their daily alcohol consumption, its cost, their response to potential price increases and strategies previously used when unable to afford alcohol. Mean and median number of standard drinks consumed per day was 24, at a median cost of $25 NZD (95%CI $22, $30). Thirty-six per cent (95%CI 26%, 46%) of the group bought alcohol at $1 or less per standard drink, and the median number of drinks consumed per day (30) by this group was significantly higher (p=0.0028) than the rest of the sample (22.5). The most common strategy used if no money was available to purchase alcohol was to forgo essentials. If facing a potential price rise, 77% (95%CI 69%, 85%) would switch wholly or partially to a cheaper product and 13% (95%CI 8%, 21%) would cut down their drinking. Although the majority of our group would be financially impacted by an increase in the minimum price per standard drink, any potential impacts would be most significant in those buying the cheapest alcohol (who also drink the most), suggesting that minimum pricing may be an important harm minimisation strategy in this group. A minimum price per standard drink would limit the possibility of switching to an alternate cheaper product and likely result in an overall reduction in alcohol consumption in this group. Stealing alcohol, or the use of non-beverage alcohol, were seldom reported as previous strategies used in response to unaffordable alcohol and fears of such are not valid reasons for rejecting minimum pricing to reduce general population consumption.

Alcohol Denat. is the generic term used by the cosmetics industry to describe denatured alcohol. Alcohol Denat. and various specially denatured (SD) alcohols are used as cosmetic ingredients in a wide variety of products. Many denaturants have been previously considered, on an individual basis, as cosmetic ingredients by the Cosmetic Ingredient Review (CIR) Expert Panel, whereas others, including Brucine and Brucine Sulfate, Denatonium Benzoate, and Quassin, have not previously been evaluated. Quassin is a bitter alkaloid obtained from the wood of Quassia amara. Quassin has been used as an insect antifeedant and insecticide and several studies demonstrate its effectiveness. At oral doses up to 1000 mg/kg using rats, Quassin was not toxic in acute and short-term tests, but some reversible piloerection, decrease in motor activity, and a partial loss of righting reflex were found in mice at 500 mg/kg. At 1000 mg/kg given intraperitoneally (i.p.), all mice died within 24 h of receiving treatment. In a cytotoxicity test with brine shrimp, 1 mg/ml of Quassin did not possess any cytotoxic or antiplasmodial activity. Quassin administered to rat Leydig cells in vitro at concentrations of 5-25 ng/ml inhibited both the basal and luteinizing hormone (LH)-stimulated testosterone secretion in a dose-related fashion. Quassin at doses up to 2.0 g/kg in drinking water using rats produced no significant effect on the body weights, but the mean weights of the testes, seminal vesicles, and epididymides were significantly reduced, and the weights of the anterior pituitary glands were significantly increased. The sperm counts and levels of LH, follicle-stimulating hormone (FSH), and testosterone were significantly lower in groups treated with Quassin. Brucine is a derivative of 2-hydroxystrychnine. Swiss-Webster mice given Brucine base, 30 ml/kg, had an acute oral LD(50) of 150 mg/kg, with central nervous system depression followed by convulsions and seizures in some cases. In those

3-hydroxy acids, 3-hydroxy-3,7-dimethyloct-6-enoic acid (1) and 3-hydroxy-2,2,3,7-tetramethyloct-6-enoic acid (2), were prepared from 6-methyl-5-hepten-2-one, and they were subsequently used to prepare (2,6,6-trimethyltetrahydropyran-2-yl)acetic acid (3) and 2-methyl-2-(2,6,6-trimethyltetrahydropyran-2-yl)propanoic acid (4), respectively, via cyclization with an acidic catalyst such as boron trifluoride diethyl etherate or iodine. The reaction of carboxylic acids 3 and 4 with alcohols, including methanol, ethanol, and 1-propanol, produced the corresponding methyl, ethyl, and propyl esters, which all contained a tetrahydropyran ring. Reduction of carboxylic acids 3 and 4 afforded the corresponding alcohols. Subsequent reactions of these alcohols with several acyl chlorides produced novel esters. The alcohols also reacted with methyl iodide and sodium hydride to provide novel ethers. A one-pot cyclization-esterification of 1 to produce esters containing a tetrahydropyran ring, using iodine as a catalyst, was also investigated.

Alcoholic ketosis and ketoacidosis are metabolic abnormalities often diagnosed in alcoholics in emergency departments. We attempted to identify determinants or factors associated with alcoholic ketosis. The subjects of this cross-sectional survey were 1588 Japanese alcoholic men (≥40 years) who came to an addiction center within 14 days of their last drink. The results of the dipstick urinalyses revealed a prevalence of ketosis of 34.0% (±, 21.5%; +, 8.9%; and 2+/3+; 3.6%) in the alcoholics. Higher urine ketone levels were associated with higher serum total bilirubin, aspartate transaminase (AST), alanine transaminase and gamma-glutamyl transpeptidase levels. A multivariate analysis by the proportional odds model showed that the odds ratio (95% confidence interval) for an increase in ketosis by one category was 0.94 (0.84-1.06) per 10-year increase in age, 0.93 (0.89-0.97) per 1-day increase in interval since the last drink, 1.78 (1.41-2.26) in the presence of slow-metabolizing alcohol dehydrogenase-1B (ADH1B*1/*1), 1.61 (1.10-2.36) and 1.30 (1.03-1.65) when the beverage of choice was whiskey and shochu, respectively (distilled no-carbohydrate beverages vs. the other beverages), 2.05 (1.27-3.32) in the presence of hypoglycemia Ketosis was a very common complication and frequently accompanied by alcoholic liver injury in our Japanese male alcoholic population, in which ADH1B*1/*1 genotype, consumption of whiskey or shochu, hypoglycemia, lower BMI and smoking were significant determinants of the development of ketosis. © The Author 2014.

Gordon, Ross

2011-11-01

The study investigated the nature and content of alcohol brand websites in the UK. The research involved an audit of the websites of the 10 leading alcohol brands by sales in the UK across four categories: lager, spirits, Flavoured Alcoholic Beverages and cider/perry. Each site was visited twice over a 1-month period with site features and content recorded using a pro-forma. The content of websites was then reviewed against the regulatory codes governing broadcast advertising of alcohol. It was found that 27 of 40 leading alcohol brands had a dedicated website. Sites featured sophisticated content, including sports and music sections, games, downloads and competitions. Case studies of two brand websites demonstrate the range of content features on such sites. A review of the application of regulatory codes covering traditional advertising found some content may breach the codes. Study findings illustrate the sophisticated range of content accessible on alcohol brand websites. When applying regulatory codes covering traditional alcohol marketing channels it is apparent that some content on alcohol brand websites would breach the codes.

A ban on multi-buy discounts of off-trade alcohol was introduced as part of the Alcohol Act in Scotland in October 2011. The aim of this study was to assess the impact of this legislation on alcohol sales, which provide the best indicator of population consumption. Interrupted time-series regression was used to assess the impact of the Alcohol Act on alcohol sales among off-trade retailers in Scotland. Models accounted for underlying seasonal and secular trends and were adjusted for disposable income, alcohol prices and substitution effects. Data for off-trade retailers in England and Wales combined (EW) provided a control group. Weekly data on the volume of pure alcohol sold by off-trade retailers in Scotland and EW between January 2009 and September 2012. The introduction of the legislation was associated with a 2.6% (95% CI = -5.3 to 0.2%, P = 0.07) decrease in off-trade alcohol sales in Scotland, but not in EW (-0.5%, 95% CI = -4.6 to 3.9%, P = 0.83). A statistically significant reduction was observed in Scotland when EW sales were adjusted for in the analysis (-1.7%, 95% CI = -3.1 to -0.3%, P = 0.02). The decline in Scotland was driven by reduced off-trade sales of wine (-4.0%, 95% CI = -5.4 to -2.6%, P types in Scotland, or in sales of any drink type in EW. The introduction of the Alcohol Act in Scotland in 2011 was associated with a decrease in total off-trade alcohol sales in Scotland, largely driven by reduced off-trade wine sales. © 2014 The Authors.

Full Text Available In this paper, emerging 5G mobile services are investigated and categorized from the perspective of not service providers, but end-users. The development of 5G mobile services is based on an intensive analysis of the global trends in mobile services. Additionally, several indispensable service requirements, essential for realizing service scenarios presented, are described. To illustrate the changes in societies and in daily life in the 5G era, five megatrends, including the explosion of mobile data traffic, the rapid increase in connected devices, everything on the cloud, hyper-realistic media for convergence services and knowledge as a service enabled by big-data analysis, are examined. Based on such trends, we classify the new 5G services into five categories in terms of the end-users’ experience as follows: immersive 5G services, intelligent 5G services, omnipresent 5G services, autonomous 5G services and public 5G services. Moreover, several 5G service scenarios in each service category are presented, and essential technical requirements for realizing the aforementioned 5G services are suggested, along with a competitiveness analysis on 5G services/devices/network industries and the current condition of 5G technologies.

Full Text Available Abstract Background Excess alcohol consumption has serious adverse effects on health and violence-related harm. In the UK around 37% of men and 29% of women drink to excess and 20% and 13% report binge drinking. The potential impact on population health from a reduction in consumption is considerable. One proposed method to reduce consumption is to reduce availability through controls on alcohol outlet density. In this study we investigate the impact of a change in the density of alcohol outlets on alcohol consumption and alcohol-related harms to health in the community. Methods/Design A natural experiment of the effect of change in outlet density between 2005–09, in Wales, UK; population 2.4 million aged 16 years and over. Data on outlets are held by the 22 local authorities in Wales under The Licensing Act 2003. The study outcomes are change in (1 alcohol consumption using data from annual Welsh Health Surveys, (2 alcohol-related hospital admissions using the Patient Episode Database for Wales, (3 Accident & Emergency department attendances between midnight–6am, and (4 alcohol-related violent crime against the person, using Police data. The data will be anonymously record-linked within the Secure Anonymised Information Linkage Databank at individual and 2001 Census Lower Super Output Area levels. New methods of network analysis will be used to estimate outlet density. Longitudinal statistical analysis will use (1 multilevel ordinal models of consumption and logistic models of admissions and Accident & Emergency attendance as a function of change in individual outlet exposure, adjusting for confounding variables, and (2 spatial models of the change in counts/rates of each outcome measure and outlet density. We will assess the impact on health inequalities and will correct for population migration. Discussion This inter-disciplinary study requires expertise in epidemiology and public health, health informatics, medical statistics

Effects of Specific Alcohol Control Policy Measures on Alcohol-Related Mortality in Russia from 1998 to 2013.

Khaltourina, Daria; Korotayev, Andrey

2015-09-01

To elucidate the possible effects of alcohol control policy measures on alcohol-related mortality in Russia between 1998 and 2013. Trends in mortality, alcohol production and sales were analyzed in conjunction with alcohol control legislative measures. Correlation analysis of health and alcohol market indicators was performed. Ethyl alcohol production was the strongest correlate of alcohol-related mortality, which is probably due to the fact that ethyl alcohol is used for both recorded and unrecorded alcohol production. Measures producing greatest mortality reduction effect included provisions which reduced ethyl alcohol production (introduction of minimum authorized capital for ethyl alcohol and liquor producers in 2006 and the requirement for distillery dreg processing), as well as measures to tax and denaturize ethanol-containing liquids in 2006. Liquor tax decrease in real terms was associated with rising mortality in 1998-1999, while excise tax increase was associated with mortality reduction in 2004 and since 2012. Conventional alcohol control measures may also have played a moderately positive role. Countries with high alcohol-related mortality should aim for a reduction in spirits consumption as a major health policy. Alcohol market centralization and reduction of the number of producers can have immediate strong effects on mortality. These measures should be combined with an increase in alcohol taxes and prices, as well as other established alcohol policy measures. In 2015 in Russia, this is not being implemented. In Russia, legislation enforcement including excise tax collection remains the major challenge. Another challenge will be the integration into the Eurasian Economic Union. © The Author 2015.

2011-02-01

Severe obesity remains the leading public health crisis of the industrialized world, with bariatric surgery the only effective and enduring treatment. Poor psychological adjustment has been occasionally reported postoperatively. In addition, evidence suggests that patients can metabolize alcohol differently after gastric bypass. Preoperatively and at 3 and 6 months postoperatively, 19 Roux-en-Y gastric bypass (RYGB) patients' breath alcohol content (BAC) was measured every 5 minutes after drinking 5 oz red wine to determine peak BAC and time until sober in a case-crossover design preoperatively and at 6 months postoperatively. Patients reported symptoms experienced when intoxicated and answered a questionnaire of drinking habits. The peak BAC in patients after RYGB was considerably higher at 3 months (0.059%) and 6 months (0.088%) postoperatively than matched preoperative levels (0.024%). Patients also took considerably more time to return to sober at 3 months (61 minutes) and 6 months (88 minutes) than preoperatively (49 minutes). Postoperative intoxication was associated with lower levels of diaphoresis, flushing, and hyperactivity and higher levels of dizziness, warmth, and double vision. Postoperative patients reported drinking considerably less alcohol, fewer preferred beer, and more preferred wine than before surgery. This is the first study to match preoperative and postoperative alcohol metabolism in gastric bypass patients. Post-RYGB patients have much higher peak BAC after ingesting alcohol and require more time to become sober. Patients who drink alcohol after gastric bypass surgery should exercise caution.

Alcohol Misuse and Multiple Sexual Partners

Directory of Open Access Journals (Sweden)

Shahrzad Bazargan-Hejazi, PhD

2012-05-01

Full Text Available Introduction: We examine the association between self-reported alcohol misuse and alcohol usewithin 2 hours of having sex and the number of sexual partners among a sample of African-Americanand Latino emergency department (ED patients.Methods: Cross-sectional data were collected prospectively from a randomized sample of all EDpatients during a 5-week period. In face-to-face interviews, subjects were asked to report their alcoholuse and number of sexual partners in the past 12 months. Data were analyzed using multiple variablenegative binomial regression models, and effect modification was assessed through inclusion ofinteraction terms.Results: The 395 study participants reported an average of 1.4 (standard error¼0.11 sexual partnersin the past 12 months, 23% reported misusing alcohol, and 28% reported consuming alcohol beforesex. There was no statistically significant association between alcohol misuse and the number ofsexual partners; however, alcohol before sex was associated with a larger number of sexual partners inthe past year. Moreover, among those who misused alcohol, participants who reported alcohol beforesex were 3 times more likely to report a higher number of sexual partners (risk ratio¼3.2; confidenceinterval [CI]¼1.9–5.6. The association between alcohol use before sex and number of sexual partnersis dependent upon whether a person has attributes of harmful drinking over the past 12 months.Overall, alcohol use before sex increases the number of sexual partners, but the magnitude of thiseffect is significantly increased among alcohol misusers.Conclusion: Alcohol misusers and those who reported having more than 1 sexual partner were morelikely to cluster in the same group, ie, those who used alcohol before sex. Efforts to reduce the burdenof sexually transmitted diseases, including human immunodeficiency virus, and other consequences ofrisky sexual behavior in the ED population should be cognizant of the interplay of alcohol and

Physicochemical properties of manganese dioxide synthesized using C2–C5 alcohols as reducing agents and their catalytic activities for CO oxidation

KAUST Repository

2015-09-26

MnO2 catalysts were synthesized in an aqueous solution of KMnO4 and C2–C5 alcohols using a simple redox method at room temperature. The crystalline structure of all samples was δ-MnO2 after being calcined at 300 °C. However, other physicochemical properties of the samples varied depending on the symmetry of the alcohols used. For the catalytic oxidation of CO, MnO2 catalysts prepared with 1° alcohols performed better than the samples prepared in 2° alcohols. Catalytic activities were correlated to the quantity of labile oxygen species of the catalysts. In CO-TPD analysis, the relative area of desorbed radical dotCO2, which is the product of the reaction between adsorbed CO and lattice oxygen species, becomes larger for MnO2 prepared with 1° alcohols than with 2° alcohols. These results were primarily resulted from the innate hydrogen dissociation behavior of alcohol in solution. The pKa was found to be an important factor in determining the physicochemical properties and catalytic activity toward CO oxidation of MnO2.

There has been a significant increase in the availability of online programs for alcohol problems. A systematic review of the research evidence underpinning these programs is timely. Our objective was to review the efficacy of online interventions for alcohol misuse. Systematic searches of Medline, PsycINFO, Web of Science, and Scopus were conducted for English abstracts (excluding dissertations) published from 1998 onward. Search terms were: (1) Internet, Web*; (2) online, computer*; (3) alcohol*; and (4) E\\effect*, trial*, random* (where * denotes a wildcard). Forward and backward searches from identified papers were also conducted. Articles were included if (1) the primary intervention was delivered and accessed via the Internet, (2) the intervention focused on moderating or stopping alcohol consumption, and (3) the study was a randomized controlled trial of an alcohol-related screen, assessment, or intervention. The literature search initially yielded 31 randomized controlled trials (RCTs), 17 of which met inclusion criteria. Of these 17 studies, 12 (70.6%) were conducted with university students, and 11 (64.7%) specifically focused on at-risk, heavy, or binge drinkers. Sample sizes ranged from 40 to 3216 (median 261), with 12 (70.6%) studies predominantly involving brief personalized feedback interventions. Using published data, effect sizes could be extracted from 8 of the 17 studies. In relation to alcohol units per week or month and based on 5 RCTs where a measure of alcohol units per week or month could be extracted, differential effect sizes to posttreatment ranged from 0.02 to 0.81 (mean 0.42, median 0.54). Pre-post effect sizes for brief personalized feedback interventions ranged from 0.02 to 0.81, and in 2 multi-session modularized interventions, a pre-post effect size of 0.56 was obtained in both. Pre-post differential effect sizes for peak blood alcohol concentrations (BAC) ranged from 0.22 to 0.88, with a mean effect size of 0.66. The available

Full Text Available Introduction: The expansion of methadone maintenance treatment (MMT program requires more data about the factors affecting the effectiveness of treatment, especially behavioral data such as smoking and alcohol use among patients. This study aimed to examine the prevalence of tobacco and alcohol consumption and identify related factors among MMT patients in the Vietnamese rural mountainside. Methods: We interviewed 241 MMT patients in two clinics in Tuyen Quang, a mountainous province in Vietnam. Patients were asked to report the smoking status (current smoker or not, nicotine dependence (by Fagerström test for nicotine dependence - FTND and alcohol use (by using the Alcohol Use Disorders Identification Test – AUDIT-C. EuroQol-5 dimensions-5 levels (EQ-5D-5L and EQ-Visual analogue scale (EQ-VAS were employed to measure health-related quality of life. Multivariate logistic and Tobit regressions were used to identify the associated factors. Results: The majority of respondents were current smokers (75.7% and a low proportion were hazardous drinkers (18.3%. People receiving treatment in a rural clinic (OR=0.45; 95%CI=0.22–0.92 and had problems in usual activities (OR=0.20; 95%CI=0.06–0.70 were less likely to be smokers. Q-VAS score (Coef.=0.03; 95%CI=0.02–0.05 and having problems in mobility (Coef.=0.72; 95%CI=0.03–1.42 was found to be associated with the increase of nicotine dependence. In terms of alcohol drinking, people with other jobs were more likely to drink hazardously compared to unemployed patients (OR=2.86; 95%CI=1.20–6.82. Similarly, patients having higher duration of MMT had higher likelihood of being hazardous drinkers (OR=1.07; 95%CI=1.01–1.13. Conclusions: This study highlights the low rate of alcohol abusers but a considerably high proportion of current smokers among MMT patients in the rural mountainside area. Alcohol and tobacco counseling programs combined with social and family support also play an essential role

The effect of swimming on the somatic and bone growth of female rats subjected to two experimental models to reproduce hormone deficiency was assessed.Twenty-eight Wistar, neonate female rats separated in two groups: Monosodium glutamate (MGlu, n = 14; solution of monosodium glutamate 4.0mg/g, alternate days, first 14 days of life and Saline Group (SAL, n = 14; saline solution. Body weight and measurements of somatic development (latero-lateral axis of the skull, anterior-posterior axis of the skull - LLS / APS - and length of the tail - LT were evaluated from the 1st to the 30th day of life. At 60 days of life, the MGlu group was ovariectomized and SAL just went though surgical stress. Subsequently, half of the animals in each group started the swimming training (12 weeks, 5 days/week, 60 min/session, resulting in the following experimental groups: Sedentary saline (Sedsal, n = 7, Swimming saline (Swisal, n = 7, Sedentary glutamate ovariectomy (SedMGluO, n = 7 and Swimming glutamate ovariectomy (SwiMGluO, n = 7.At the end of the experiment, the right femur was weighed and its length assessed. At the 30 initial days, the MGlu group reduced its body weight and the LLS, APC and LT compared to SAL. At day 60, body weight of MGlu group remained lower and at the end of the experiment it was similar between Swisal and Sedsal groups; SedMGLuO and SwiMGluO groups. However, weight reduction was observed in SedMGlutO compared to SedSAL. Swimming helped the weight of the femur in the SAL and did not alter it between SedMGluO and SwiMGluO, but it increased in Sedsal compared to SedMGluO group. In length, the SwiSal was similar to Sedsal and the same situation occurred between SwiMGluO and SedMGluO. However, Sedsal group presented greater length than SedMGluO. Swimming was not able to reverse the effects caused by situations of

Research evidence points to harmful effects from alcohol advertising among children and youth. In particular, exposure to alcohol advertising has been associated with adolescents drinking both earlier and heavier. Although current federal and provincial guidelines have addressed advertising practices to prevent underage drinking, practice has not been supported by existing policy. While protective measures such as social marketing campaigns have the potential for counteracting the effects from alcohol advertising, the effectiveness of such measures can be easily drowned out with increasing advertising activities from the alcohol industry, especially without effective regulation. Research reviewed by the European Focus on Alcohol Safe Environment (FASE) Project has identified a set of key elements that are necessary to make alcohol advertising policy measures effective at protecting children and youth from the harmful effects of alcohol marketing. Using these key elements as an evaluation framework, there are critical components in the Canadian alcohol advertising regulatory system that clearly require strengthening. To protect impressionable children and youth against the harmful effects of alcohol advertising, 13 recommendations to strengthen current alcohol advertising regulations in Canada are provided for Canadian policy-makers, advertising standard agencies, and public health groups.

Full Text Available BACKGROUND Alcohol affects many organs, especially the liver, pancreas and brain. Although, the beneficial effects of mild or moderate ethanol consumption have been implied with respect to coronary artery disease, excessive ethanol consumption can result in Alcoholic Heart Muscle Disease (AHMD. AIMS Alcohol consumption, mainly arrack, is common social problem in Mangalore. This study has been undertaken to assess the effects of alcohol on cardiovascular system. MATERIALS AND METHODS Thirty patient with history of consumption of about 6 units of alcohol per day for at least 5 days a week for at least 5 years who were admitted to Government Wenlock Hospital, Attavar K.M.C. and University Medical Centre, Mangalore, were selected as case and studied. RESULTS Alcohol intake is predominantly observed in males, majority of alcoholic had high blood pressure, serum levels of CPK-MB and LDH are elevated in chronic alcoholic patients, left ventricular hypertrophy, premature ventricular contraction and sinus tachycardia were common findings in the electrocardiograms of chronic alcoholic patients and development of alcoholic heart muscle disease is directly proportional to the quantity and duration of alcohol intake. CONCLUSION Overall, the present study has found high morbidity from chronic alcohol consumption highlighting the need for preventive measures to tackle this preventable hazard.

It is widely accepted that dopamine and serotonin (5-HT) neurotransmission can be critically involved in the development of alcohol abuse and alcohol dependence. Lesch's typology of alcoholism has been gaining increasing popularity as it qualitatively differentiates patients into different treatment response subgroups. The aim of the present study was to evaluate a possible genetic background of Lesch's typology with special emphasis placed on dopamine- and serotonin-related genes. 122 alcoholics (the mean age: 35+/-9 years) were investigated. According to Lesch's typology, 58 patients were of type I, 36 patients of type II, 11 patients of type III, and 17 patients of type IV. Alcohol drinking and family history was assessed by means of a structured interview, based on the Semi-Structured Assessment for the Genetics of Alcoholism. 150 control subjects without psychiatric disorders were also recruited. The control group was ethnically-, age- and gender-matched to the patients. The DRD2 TaqIA, exon 8, and promoter -141C ins/del polymorphisms as well as COMT Val158Met, 5HTT 44 bp del in promoter, and DAT 40 bp VNTR polymorphisms were detected by means of PCR. No significant differences were observed when the whole group of alcoholics and the controls were compared. Similarly, there were no differences between either the Lesch type I or type II alcoholics and the control subjects. No significant differences were observed between type I and type II alcoholics. Alleles frequencies were not calculated for the Lesch type III and type IV alcoholics since the number of patients was too small. The present results argue against any major role of the investigated polymorphisms in either Lesch type I or type II alcoholism. More comprehensive studies are needed to define the role of the investigated polymorphisms in Lesch type III and type IV alcoholism.

2007-05-01

Full Text Available Abstract Background While alcohol-related health and social problems amongst youths are increasing internationally, both consumption and associated harms are particularly high in British youth. Youth drinking patterns, including bingeing, frequent drinking and drinking in public spaces, are associated with increased risks of acute (e.g. violence and long-term (e.g. alcohol-dependence health problems. Here we examine economic, behavioural and demographic factors that predict these risky drinking behaviours among 15–16 year old schoolchildren who consume alcohol. A cross-sectional survey was conducted among schoolchildren in North West England (n = 10,271 using an anonymous questionnaire delivered in school settings. Analysis utilised logistic regression to identify independent predictors of risky drinking behaviour. Results Of all respondents, 87.9% drank alcohol. Of drinkers, 38.0% usually binged when drinking, 24.4% were frequent drinkers and 49.8% drank in public spaces. Binge, frequent and public drinking were strongly related to expendable income and to individuals buying their own alcohol. Obtaining alcohol from friends, older siblings and adults outside shops were also predictors of risky drinking amongst drinkers. However, being bought alcohol by parents was associated with both lower bingeing and drinking in public places. Membership of youth groups/teams was in general protective despite some association with bingeing. Conclusion Although previous studies have examined predictors of risky drinking, our analyses of access to alcohol and youth income have highlighted eradicating underage alcohol sales and increased understanding of children's spending as key considerations in reducing risky alcohol use. Parental provision of alcohol to children in a family environment may also be important in establishing child-parent dialogues on alcohol and moderating youth consumption. However, this will require supporting parents to ensure they

Evidence supports the expectation that changes in time of alcohol sales associate with changes in alcohol-related harm in both directions. However, to the best of our knowledge, no comprehensive systematic reviews had examined the effect of policies restricting time of alcohol trading on specific alcohol-related harms. To compile existing evidence related to the impact of policies regulating alcohol trading hours/days of on specific harm outcomes such as: assault/violence, motor vehicle crashes/fatalities, injury, visits to the emergency department/hospital, murder/homicides and crime. Systematic review of literature studying the impact of policies regulation alcohol trading times in alcohol-related harm, published between January 2000 and October 2016 in English language. Results support the premise that policies regulating times of alcohol trading and consumption can contribute to reduce injuries, alcohol-related hospitalisations/emergency department visits, homicides and crime. Although the impact of alcohol trading policies in assault/violence and motor vehicle crashes/fatalities is also positive, these associations seem to be more complex and require further study. Evidence suggests a potential direct effect of policies that regulate alcohol trading times in the prevention of injuries, alcohol-related hospitalisations, homicides and crime. The impact of these alcohol trading policies in assault/violence and motor vehicle crashes/fatalities is less compelling. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

This is the first study to examine the effect of alcohol marketing exposure on adolescents' drinking in a cross-national context. The aim was to examine reciprocal processes between exposure to a wide range of alcohol marketing types and adolescent drinking, controlled for non-alcohol branded media exposure. Prospective observational study (11-12- and 14-17-month intervals), using a three-wave autoregressive cross-lagged model. School-based sample in 181 state-funded schools in Germany, Italy, Netherlands, Poland. A total of 9075 eligible respondents participated in the survey (mean age 14 years, 49.5% male. Adolescents reported their frequency of past-month drinking and binge drinking. Alcohol marketing exposure was measured by a latent variable with 13 items measuring exposure to online alcohol marketing, televised alcohol advertising, alcohol sport sponsorship, music event/festival sponsorship, ownership alcohol-branded promotional items, reception of free samples and exposure to price offers. Confounders were age, gender, education, country, internet use, exposure to non-alcohol sponsored football championships and television programmes without alcohol commercials. The analyses showed one-directional long-term effects of alcohol marketing exposure on drinking (exposure T1 on drinking T2: β = 0.420 (0.058), P  0.05). Similar results were found in the binge drinking model (exposure T1 on binge T2: β = 0.409 (0.054), P  0.05). There appears to be a one-way effect of alcohol marketing exposure on adolescents' alcohol use over time, which cannot be explained by either previous drinking or exposure to non-alcohol-branded marketing. © 2016 Society for the Study of Addiction.

Harmful use of alcohol is one of the globally recognized causes of health hazards. There are no data on alcohol consumption from Andaman and Nicobar Islands. The objective of the study was to assess the prevalence and pattern of alcohol use among the population of Andaman and Nicobar Islands, India. A representative sample of 18,018 individuals aged ≥14 years were chosen by multistage random sampling and administered a structured instrument, a modified version of the Gender, Alcohol, and Culture: An International Study (GENACIS) which included sociodemographic details and Alcohol Use Disorders Identification Test (AUDIT). The overall prevalence of alcohol consumption was 35% among males and over 6.0% in females, aged 14 and above. Two out of every five alcohol users fit into a category of hazardous drinkers. One-fourth of the total users (23%) are alcohol dependents. Both the hazardous drinking and dependent use are high among males compared to females. Almost 18.0% of male drinkers and 12.0% of female drinkers reported heavy drinking on typical drinking occasions. The predominant beverages consumed were in the category of homebrews such as toddy and handia. The present study highlights the magnitude of hazardous drinking and alcohol dependence in Andaman and Nicobar Islands, India and the complex sociocultural differences in the pattern of alcohol use. Based on the AUDIT data, among the population of Andaman and Nicobar Islands (aged 14 and above), one out of ten requires active interventions to manage the harmful impact of alcohol misuse.

Serotonin's Complex Role in Alcoholism: Implications for Treatment and Future Research.

2016-06-01

Current pharmacological treatments for alcohol dependence have focused on reducing alcohol consumption, but to date there are few treatments that also address the negative affective symptoms during acute and protracted alcohol withdrawal which are often exacerbated in people with comorbid anxiety and depression. Selective serotonin reuptake inhibitors (SSRIs) are sometimes prescribed to ameliorate these symptoms but can exacerbate anxiety and cravings in a select group of patients. In this critical review, we discuss recent literature describing an association between alcohol dependence, the SERT linked polymorphic region (5-HTTLPR), and pharmacological response to SSRIs. Given the heterogeneity in responsiveness to serotonergic drugs across the spectrum of alcoholic subtypes, we assess the contribution of specific 5-HT circuits to discrete endophenotypes of alcohol dependence. 5-HT circuits play a distinctive role in reward, stress, and executive function which may account for the variation in response to serotonergic drugs. New optogenetic and chemogenetic methods for dissecting 5-HT circuits in alcohol dependence may provide clues leading to more effective pharmacotherapies. Although our current understanding of the role of 5-HT systems in alcohol dependence is incomplete, there is some evidence to suggest that 5-HT3 receptor antagonists are effective in people with the L/L genotype of the 5-HTTLPR polymorphism while SSRIs may be more beneficial to people with the S/L or S/S genotype. Studies that assess the impact of serotonin transporter polymorphisms on 5-HT circuit function and the subsequent development of alcohol use disorders will be an important step forward in treating alcohol dependence.

Shankhwar, Nisha; Kumar, Manishekhar; Mandal, Biman B.; Srinivasan, A.

2016-01-01

Composite nanofibrous membranes based on sol-gel derived 45SiO 2 24.5CaO 24.5 Na 2 O 6 P 2 O 5 (bioglass, BG) and 43SiO 2 24.5CaO 24.5 Na 2 O 6 P 2 O 5 2Fe 2 O 3 (magnetic bioglass, MBG) blended with polyvinyl alcohol (PVA) have been electrospun. These low cost membranes were mostly amorphous in structure with minor crystalline (sodium calcium phosphate) precipitates. All membranes were biodegradable. Among these, the composites exhibited higher tensile strength, better proliferation of human osteosarcoma MG63 cells and higher alkaline phosphatase enzyme activity than the bare PVA membrane, indicating their potential in bone tissue engineering. The magnetic PVA-MBG scaffold was also found to be a promising candidate for magnetic hyperthermia application. - Highlights: • Electrospun low-cost PVA-45S5 bioglass (BG) nanofibrous membranes • PVA-BG membranes containing 2 wt.% Fe 2 O 3 exhibit spontaneous magnetization. • BG fillers strongly enhanced mechanical strength and bioresponse of membranes. • Membranes show promise for bone scaffold and hyperthermia applications.

2014-06-01

The average U.S. adolescent is exposed to about 2.5 hours of popular music and 8 mentions of alcohol brands every day. Alcohol brand mentions may function as advertising whether or not they are sanctioned by the alcohol industry. Our study aimed to determine associations between adolescents' involvement with music containing alcohol brand mentions and alcohol-related behaviors. In 2010 to 2011, we conducted a random-digit-dial survey using national U.S. land line and cell phone frames. Through screening interviews, we identified 6,466 eligible households with subjects between 15 and 23 years of age, of whom 3,422 (53%) completed the telephone survey. Of these, 2,541 opted to participate in a subsequent web-based component. Independent variables included a composite score indicating owning and liking popular songs with alcohol brand mentions and correct recall of alcohol brands in songs. Outcome measures included ever having consumed a complete drink, ever bingeing, bingeing at least monthly, and having experienced problems from alcohol use. Among the 2,541 participants, compared with those in the lowest tertile on the receptivity scale, those in the highest tertile had higher odds of having had a complete drink (OR = 3.4; 95% CI = 2.2, 5.2) after adjusting for age, sex, race/ethnicity, socioeconomic status, sensation seeking, friend alcohol use, and parent alcohol use. Compared with those who did not identify at least 1 alcohol brand correctly, those who did had over twice the odds of having had a complete drink (OR = 2.1; 95% CI = 1.2, 3.8) after adjusting for all covariates. Results were also significant for the outcome of ever bingeing, but not for bingeing at least monthly or having had problems due to drinking. In a national sample of U.S. adolescents and young adults, there were independent associations between involvement with popular music containing alcohol brand mentions and both having ever had a complete drink and having ever binged on alcohol

Alcohol Demand, Future Orientation, and Craving Mediate the Relation Between Depressive and Stress Symptoms and Alcohol Problems.

Elevated depression and stress have been linked to greater levels of alcohol problems among young adults even after taking into account drinking level. This study attempts to elucidate variables that might mediate the relation between symptoms of depression and stress and alcohol problems, including alcohol demand, future time orientation, and craving. Participants were 393 undergraduates (60.8% female, 78.9% White/Caucasian) who reported at least 2 binge-drinking episodes (4/5+ drinks for women/men, respectively) in the previous month. Participants completed self-report measures of stress and depression, alcohol demand, future time orientation, craving, and alcohol problems. In separate mediation models that accounted for gender, race, and weekly alcohol consumption, future orientation and craving significantly mediated the relation between depressive symptoms and alcohol problems. Alcohol demand, future orientation, and craving significantly mediated the relation between stress symptoms and alcohol problems. Heavy-drinking young adults who experience stress or depression are likely to experience alcohol problems, and this is due in part to elevations in craving and alcohol demand, and less sensitivity to future outcomes. Interventions targeting alcohol misuse in young adults with elevated levels of depression and stress should attempt to increase future orientation and decrease craving and alcohol reward value.

2011-02-01

Previous research has documented a relationship between child sexual abuse and alcohol dependence. This paper extends that work by providing a comprehensive description of past year and lifetime alcohol consumption patterns, consequences, and dependence among women reporting either physical and sexual abuse in a national sample. This study used survey data from 3,680 women who participated in the 2005 U.S. National Alcohol Survey. Information on physical and sexual child abuse and its characteristics were assessed in relation to 8 past year and lifetime alcohol consumption measures. Child physical or sexual abuse was significantly associated with past year and lifetime alcohol consumption measures. In multivariate analyses, controlling for age, marital status, employment status, education, ethnicity, and parental alcoholism or problem drinking, women reporting child sexual abuse vs. no abuse were more likely to report past year heavy episodic drinking (OR(adj) = 1.7; 95% CI 1.0 to 2.9), alcohol dependence (OR(adj) = 7.2; 95% CI 3.2 to 16.5), and alcohol consequences (OR(adj) = 3.6; 95% CI 1.8 to 7.3). Sexual abuse (vs. no abuse) was associated with a greater number of past year drinks (124 vs. 74 drinks, respectively, p = 0.002). Sexual child abuse was also associated with lifetime alcohol-related consequences (OR(adj) = 3.5; 95% CI 2.6 to 4.8) and dependence (OR(adj) = 3.7; 95% CI 2.6 to 5.3). Physical child abuse was associated with 4 of 8 alcohol measures in multivariate models. Both physical and sexual child abuse were associated with getting into fights, health, legal, work, and family alcohol-related consequences. Alcohol-related consequences and dependence were more common for women reporting sexual abuse compared to physical abuse, 2 or more physical abuse perpetrators, nonparental and nonfamily physical abuse perpetrators, and women reporting injury related to the abuse. Both child physical and sexual abuse were associated with many alcohol outcomes in

Polysubstance Abuse: Alcohol, Opioids and Benzodiazepines Require Coordinated Engagement by Society, Patients, and Physicians

Directory of Open Access Journals (Sweden)

Ogbu, Uzor C

2015-03-01

Full Text Available The Centers for Disease Control and Prevention (CDC has published significant data trends related to substance abuse involving opioid pain relievers (OPR, benzodiazepines and alcohol in the United States. The CDC describes opioid misuse and abuse as an epidemic, with the use of OPR surpassing that of illicit drugs. Alcohol has also been a persistent problem and is associated with a number of emergency department visits and deaths independent of other substances. The use of these drugs in combination creates an additive effect with increased central nervous system suppression and a heightened risk of an overdose. We present a summary of the findings from the Morbidity and Mortality Weekly Report (MMWR with commentary on strategies to combat prescription drug and alcohol abuse.

The possible impact of an alcohol welfare surcharge on consumption of alcoholic beverages in Taiwan.

Science.gov (United States)

Yeh, Chun-Yuan; Ho, Li-Ming; Lee, Jie-Min; Hwang, Jhe-Yo

2013-09-08

The abuse of alcoholic beverages leads to numerous negative consequences in Taiwan, as around the world. Alcohol abuse not only contributes to cardiovascular disease, hypertension, diabetes and cancer, but it is also an underlying cause of many other serious problems, such as traffic accidents, lost productivity, and domestic violence. International leaders in health policy are increasingly using taxation as an effective tool with which to lower alcohol consumption. In this study, we assessed how consumption patterns in Taiwan would be affected by levying a welfare surcharge on alcoholic beverages of 20%, 40% or 60% in accordance with the current excise tax. We also assessed the medical savings Taiwan would experience if consumption of alcoholic beverages were to decrease and how much additional revenue a welfare surcharge would generate. We estimated the elasticity of four types of alcoholic beverages (beer, wine, whisky and brandy) using the Central Bureau of Statistics (CBS) Demand Model. Specifically, we estimated alcohol's price elasticity by analyzing the sales prices and time statistics of these products from 1974 to 2009. Alcoholic beverages in Taiwan have the following price elasticities: beer (-0.820), wine (-0.955), whisky (-0.587), brandy (-0.958). A welfare surcharge tax of 40% in accordance with the excise tax would decrease overall consumption of beer, wine, whisky and brandy between 16.24% and 16.42%. It would also generate New Taiwan Dollar (NT$) revenues of 5.782 billion to 5.993 billion. Savings in medical costs would range from NT$871.07 million to NT$897.46 million annually. A social and welfare surcharge of 40% on alcoholic beverages in Taiwan would successfully lower consumption rates, decrease medical costs, and generate revenue that could be used to educate consumers and further decrease consumption rates. Consequently, we strongly recommend that such a tax be imposed in Taiwan.

2012-03-01

The average US adolescent is exposed to 34 references to alcohol in popular music daily. Although brand recognition is an independent, potent risk factor for alcohol outcomes among adolescents, alcohol brand appearances in popular music have not been assessed systematically. We aimed to determine the prevalence of and contextual elements associated with alcohol brand appearances in US popular music. Qualitative content analysis. We used Billboard Magazine to identify songs to which US adolescents were most exposed in 2005-07. For each of the 793 songs, two trained coders analyzed independently the lyrics of each song for references to alcohol and alcohol brand appearances. Subsequent in-depth assessments utilized Atlas.ti to determine contextual factors associated with each of the alcohol brand appearances. Our final code book contained 27 relevant codes representing six categories: alcohol types, consequences, emotional states, activities, status and objects. Average inter-rater reliability was high (κ = 0.80), and all differences were easily adjudicated. Of the 793 songs in our sample, 169 (21.3%) referred explicitly to alcohol, and of those, 41 (24.3%) contained an alcohol brand appearance. Consequences associated with alcohol were more often positive than negative (41.5% versus 17.1%, P brand appearances were associated commonly with wealth (63.4%), sex (58.5%), luxury objects (51.2%), partying (48.8%), other drugs (43.9%) and vehicles (39.0%). One in five songs sampled from US popular music had explicit references to alcohol, and one-quarter of these mentioned a specific alcohol brand. These alcohol brand appearances are associated commonly with a luxury life-style characterized by wealth, sex, partying and other drugs. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

2017-11-01

This study aimed to address 2 important aspects of temporal pattern in alcohol-related facial fractures: (1) comparison of temporal pattern of alcohol-related facial fracture (alcohol group) presentation with non-alcohol-related fracture (non-alcohol group) presentation; (2) temporal pattern of patient demographic characteristics, injury characteristics, and surgical management in the alcohol group presentation. This study retrospectively examined the Victorian admitted episodes data set (VAED) for the years 2010 to 2013. VAED is a standardized set of data collected during all hospital presentations in Victoria. The study found higher incidence of alcohol-related facial fracture presentations during weekends and during the summer and spring months compared with non-alcohol-related fractures (statistically significant). Alcohol-related facial fractures are more likely to involve male patients in the 20- to 29-year age group, occur as a result of interpersonal violence, and require shorter hospital stays during weekend admissions (statistically significant). No statistically significant relationship has been observed in seasonal variation across all variables. This study found distinct characteristics in temporal distribution of alcohol-related facial fractures. These characteristics are, in particular, significant in weekend trauma admissions. Such information is important in workforce planning, resource distribution, and implementation of injury prevention programs. Copyright © 2017 Elsevier Inc. All rights reserved.

The gendered trouble with alcohol: young people managing alcohol related violence.

Science.gov (United States)

Lindsay, Jo

2012-05-01

Alcohol related violence is a troubling backdrop to the social lives and relationships of many young people in post-industrial societies. The development of the night-time economy where young people are encouraged to drink heavily in entertainment precincts has increased the risk of violence. This paper reports on 60 individual structured in-depth interviews about the drinking biographies of young people (aged 20-24) living in Victoria, Australia. Twenty-six males and 34 females participated in the research. The participants discussed their experiences with alcohol over their life course to date. The material on alcohol related violence is analysed in this paper. Just over half of the participants (33/60) recounted negative experiences with alcohol related violence. The findings demonstrate the continuing gendered nature of experiences of perpetration and victimization. Participants reported that aggression and violence perpetrated by some men was fuelled by alcohol consumption and required ongoing management. Experiences of violence were also spatialized. Men were more likely to report managing and avoiding violence in particular public settings whilst more women than men discussed managing violence in domestic settings. The central argument of this paper is that incidents of alcohol related violence and reactions to it are specific gender performances that occur in specific socio-cultural contexts. In contrast to research which has found some young people enjoy the adventure and excitement of alcohol related violence the mainstream participants in this study saw violence as a negative force to be managed and preferably avoided. Understanding violence as a dynamic gender performance complicates the development of policy measures designed to minimize harm but also offers a more holistic approach to developing effective policy in this domain. There is a need for greater acknowledgement that alcohol related violence in public venues and in families is primarily about

Full Text Available Case report of patient who has been an alcoholic for 40 years and, after reducing alcohol intake, developed auditory and visual hallucinations, which caused behavior change. Neurological issues, electrolyte disturbances and other organ dysfunctions were excluded as cause of said change. After intake of haloperidol and risperidone, the patient had regression of symptoms and denied having presented hallucinatory symptoms. The Manual Diagnóstico e Estatístico de Transtornos Mentais – 5ª edição (DSM-V includes alcoholic hallucinosis in the Substance-Induced Psychotic Disorder (alcohol, beginning during abstinence; however, the document is not yet very well accepted among the medical community. The difficulty of the team to confirm the diagnosis of alcoholic hallucinosis lies in the differential diagnosis, as Delirium tremens and severe withdrawal syndrome with psychotic symptoms. Thus, psychopathological differentiation is important, as well as continuity of research and collaboration of other clinical teams in the evaluation.

The DSM-5 Tobacco use disorder diagnosis incorporates tobacco misuse, addictive behaviors and withdrawal symptomology. Tobacco use is bidirectionally associated with sleep pathology; however, no epidemiological studies have yet evaluated the associations between DSM-5 Tobacco use disorder and self-reported sleep disturbance. The current study aimed to evaluate health, medical and sleep-related factors among individuals within this diagnostic stratum. A total of N = 36,177 adults who participated in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were included for analyses. The adjusted odd ratios (AOR) for individual classifications of DSM-5 Tobacco use disorder among those with subjective sleep disturbances were used as the primary outcome measure and relevant demographic, clinical and medical factors were considered in all univariate and multivariable analyses. Current and lifetime DSM-5 tobacco use disorder diagnoses were associated with poorer health and medical outcomes and higher rates of subjective sleep disturbances (all p DSM-5 tobacco use disorder and subjective sleep disturbances were maintained in multivariable analyses following adjustment for a range of health, lifestyle, and psychiatric factors (adjusted OR 1.11, 95%CI 1.00-1.23 and adjusted OR = 1.24, 95%CI 1.15-1.34, respectively); however, these relationships were fully explained by diagnoses of DSM-5 alcohol use disorder. Data from this large, representative survey indicate that the association between DSM-5 Tobacco use disorder and sleep disturbance is explained by underlying diagnoses of DSM-5 alcohol use disorder. Multifaceted substance abuse treatment protocols may improve treatment outcomes for affected patient groups.

Alcoholics' selective attention to alcohol stimuli: automated processing?

Stormark, K M; Laberg, J C; Nordby, H; Hugdahl, K

2000-01-01

This study investigated alcoholics' selective attention to alcohol words in a version of the Stroop color-naming task. Alcoholic subjects (n = 23) and nonalcoholic control subjects (n = 23) identified the color of Stroop versions of alcohol, emotional, neutral and color words. Manual reaction times (RTs), skin conductance responses (SCRs) and heart rate (HR) were recorded. Alcoholics showed overall longer RTs than controls while both groups were slower in responding to the incongruent color words than to the other words. Alcoholics showed longer RTs to both alcohol (1522.7 milliseconds [ms]) and emotional words (1523.7 ms) than to neutral words (1450.8 ms) which suggests that the content of these words interfered with the ability to attend to the color of the words. There was also a negative correlation (r = -.41) between RT and response accuracy to alcohol words for the alcoholics, reflecting that the longer time the alcoholics used to respond to the color of the alcohol words, the more incorrect their responses were. The alcoholics also showed significantly greater SCRs to alcohol words (0.16 microSiemens) than to any of the other words (ranging from 0.04-0.08 microSiemens), probably reflecting the emotional significance of the alcohol words. Finally, the alcoholics evidenced smaller HR acceleration to alcohol (1.9 delta bpm) compared to neutral (2.8 delta bpm), which could be related to difficulties alcoholics experience in terminating their attention to the alcohol words. These findings indicate that it is difficult for alcoholics to regulate their attention to alcohol stimuli, suggesting that alcoholics' processing of alcohol information is automated.

The importance of alcohol as an alternative fuel has been slowly established. In countries such as Brazil, they are already used in transport and other sectors of economy. Other developing countries are also trying out experiments with alcohol fuels. Chances of improving the economy of many developing nations depends to a large extent on the application of this fuel. The potential for alcohol fuels in developing countries should be considered as part of a general biomass-use strategy. The final strategies for the development of alcohol fuel will necessarily reflect the needs, values, and conditions of the individual nations, regions, and societies that develop them.

Functional imaging studies have recently demonstrated that specific brain regions become active in cocaine addicts when they are exposed to cocaine stimuli. To test whether there are regional brain activity differences during alcohol cue exposure between alcoholic subjects and social drinkers, we designed a functional magnetic resonance imaging (fMRI) protocol involving alcohol-specific cues. Ten non-treatment-seeking adult alcoholic subjects (2 women) (mean [SD] age, 29.9 [9.9] years) as well as 10 healthy social drinking controls of similar age (2 women) (mean [SD] age, 29.4 [8.9] years) were recruited, screened, and scanned. In the 1.5-T magnetic resonance imaging scanner, subjects were serially rated for alcohol craving before and after a sip of alcohol, and after a 9-minute randomized presentation of pictures of alcoholic beverages, control nonalcoholic beverages, and 2 different visual control tasks. During picture presentation, changes in regional brain activity were measured with the blood oxygen level-dependent technique. Alcoholic subjects, compared with the social drinking subjects, reported higher overall craving ratings for alcohol. After a sip of alcohol, while viewing alcohol cues compared with viewing other beverage cues, only the alcoholic subjects had increased activity in the left dorsolateral prefrontal cortex and the anterior thalamus. The social drinkers exhibited specific activation only while viewing the control beverage pictures. When exposed to alcohol cues, alcoholic subjects have increased brain activity in the prefrontal cortex and anterior thalamus-brain regions associated with emotion regulation, attention, and appetitive behavior.

Background The average U.S. adolescent is exposed to about 2.5 hours of popular music per day and 8 mentions of alcohol brands every day. Alcohol brand mentions may function as advertising whether or not they are sanctioned by the alcohol industry. Our study aimed to determine associations between adolescents' involvement with music containing alcohol brand mentions and alcohol-related behaviors. Methods In 2010–2011 we conducted a random-digit-dial survey using national U.S. land line and cell phone frames. Through screening interviews, we identified 6,466 eligible households with subjects between 15 to 23 years of age, of whom 3422 (52%) completed the telephone survey. Of these, 2541 opted to participate in a subsequent Web-based component. Independent variables included a composite score indicating owning and liking popular songs with alcohol brand mentions and correct recall of alcohol brands in songs. Outcome measures included ever having consumed a complete drink, ever bingeing, bingeing at least monthly, and having experienced problems from alcohol use. Results Among the 2541 participants, compared with those in the lowest tertile on the receptivity scale, those in the highest tertile had higher odds of having had a complete drink (OR=3.4; 95% CI=2.2, 5.2) after adjusting for age, sex, race/ethnicity, socioeconomic status, sensation seeking, friend alcohol use, and parent alcohol use. Compared with those who did not identify at least one alcohol brand correctly, those who did had over twice the odds of having had a complete drink (OR=2.1; 95% CI=1.2, 3.8) after adjusting for all covariates. Results were also significant for the outcome of ever bingeing but not for bingeing at least monthly or having had problems due to drinking. Conclusions In a national sample of U.S. adolescents and young adults, there were independent associations between involvement with popular music containing alcohol brand mentions and both having ever had a complete drink and

This study examined the frequency and nature of alcohol marketing references in broadcasts of the 2016 UEFA (Union of European Football Associations) European Championships football tournament in the United Kingdom (UK). Eighteen matches from across the tournament were recorded in full as broadcast in the UK, including all four matches featuring the English national team and all seven featuring the French national team. All visual and verbal references to alcohol marketing were recorded using a tool with high inter-rater reliability. A total of 2213 alcohol marketing references were recorded, an average of 122.94 per broadcast and 0.65 per broadcast minute (0.52 per minute in-play and 0.80 per minute out-of-play). Almost all references were visual (97.5%), with 77.9% occurring around the pitch border. Almost all (90.6%) were indirect references to alcohol brands (e.g., references to well-known slogans), compared to only 9.4% direct references to brands (e.g., brand names). The frequency of references to alcohol marketing was high. Although the overall proportion of direct brand references was low, the high proportion of indirect references demonstrates that alcohol producers were able to circumvent the French national law governing alcohol marketing (the Loi Évin) using indirect “alibi marketing”. To ensure the spirit of the Loi Évin regulations are achieved, stricter enforcement may be required to limit exposure to alcohol marketing, particularly for young people. PMID:28661462

Alcohol-dependent individuals (ALC) simultaneously present decreased inhibitory control and increased attention towards alcohol-related cues. The dual-process models have proposed that these symptoms reflect an imbalance between prefrontal/reflective and limbic/automatic systems, respectively leading to cognitive dysfunctions in executive processes and to alcohol-related bias. However, most previous research has focused on a separate exploration of these systems among ALC, and the direct measure of their interactions remains to be conducted. Moreover, no study has explored the evolution of this imbalance across the successive stages of alcohol-related disorders, and particularly in Korsakoff syndrome (KS), the most frequent neurological complication of alcohol-dependence. Ten KS, 14 ALC, and 14 matched control participants performed a modified Flanker task, the "Alcohol Flanker Task," based on congruent, incongruent, and neutral conditions with alcohol-related stimuli. This task required inhibitory processing on alcohol-related stimuli and evaluated, through a behavioral approach, the interaction between reflective and automatic systems, as well as its evolution between ALC and KS. ALC and KS both presented high reactivity towards alcohol-related stimuli, confirming the presence of alcohol-related bias. KS showed increased omission rates (related to distractor interference) while ALC showed higher false-alarm rates (related to prepotent response inhibition). These results suggest that different inhibitory subcomponents might be altered at the successive stages of the pathology, and experimentally confirms the crucial role of the interaction between reflective and automatic processes in alcohol-use disorders. The present results reinforce the proposal that alcohol-related cues significantly impact inhibitory control in alcohol-related disorders. However, ALC and KS present different patterns of deficits depending on task complexity (i.e., executive load), thus

From the biomedical point of view alcohol is a Janus-faced dietary component with a dose-dependent effect varying from cardiovascular protection to cytotoxicity. Alcohol is absorbed in the upper gastrointestinal tract by passive diffusion, is quickly distributed throughout body water and is mostly eliminated through oxidation. The enzymatically-catalyzed oxidative degradation to acetaldehyde and further to acetate is primarily localized in the liver. In case of a low blood alcohol concentration (0.5 per thousand) are increasingly oxidized by the microsomal ethanoloxidizing system (MEOS). Alcohol consumption induces several metabolic reactions as well as acute effects on the central nervous system. Chronic alcohol consumption to some extent irreparably damages nearly every organ with the liver being particularly concerned. There are three stages of alcohol-induced liver disease (fatty liver, alcohol hepatitis, liver cirrhosis) and the liver damages mainly result from reaction products of alcohol degradation (acetaldehyde, NADH and reactive oxygen species). An especially dreaded clinical complication of the alcohol-induced liver disease is the hepatic encephalopathy. Its pathogenesis is a multifactorial and self-perpetuating process with the swelling of astrocytes being a crucial point. Swollen astrocytes induce several reactions such as oxidative/nitrosative stress, impaired signal transduction, protein modifications and a modified gene expression profile. The swelling of astrocytes and the change in neuronal activity are attributed to several neurotoxins, especially ammonia and aromatic amino acids. In alcohol addicted subjects multiple micronutrient deficiencies are common. The status of folic acid, thiamine, pyridoxine and zinc is especially critical.

was measured in 19 698 men and women randomly drawn from the Copenhagen Population Register in 1976-78. The study population was linked to three different registers in order to detect alcoholism, and average follow-up time was 25 years. RESULTS: After adjustment for all putative confounders, the risk...... of alcoholism for women increased significantly at 1-7 drinks per week with a hazard ratio (HR) of 2.02 (95% confidence interval (CI): 1.16, 3.53) compared to never/almost never drinking; the HR for drinking monthly was 1.75 (95% CI: 1.08, 2.85). The risk for men did not increase significantly before 22......-41 drinks per week (HR = 3.81, 95 % CI: 2.18, 6.68) or if they had a daily alcohol intake (HR = 3.55, 95 % CI: 2.11, 5.99). Smoking was independently associated with the risk of alcoholism for both men and women. CONCLUSION: The risk of developing alcoholism increased significantly by very low intakes...

This study investigated the relative contribution of the Big 5 personality factors and alcohol metacognitions in predicting weekly levels of alcohol use in binge drinking university students. No research to date has investigated whether either of these constructs predicts levels of weekly alcohol use in binge drinkers. A sample of university students (n=142) who were classified as binge drinkers were administered the following self-report instruments: NEO-Five Factor Inventory (NEO-FFI; Costa & McCrae, 1992), Positive Alcohol Metacognitions Scale (PAMS; Spada & Wells, 2008), Negative Alcohol Metacognitions Scale (NAMS; Spada & Wells, 2008), and Khavari Alcohol Test (KAT; Khavari & Farber, 1978). Pearson product-moment correlations showed that weekly levels of alcohol use were negatively correlated with agreeableness and conscientiousness and positively correlated with positive alcohol metacognitions about cognitive self-regulation, negative alcohol metacognitions about uncontrollability and negative alcohol metacognitions about cognitive harm. A hierarchical regression analysis revealed that conscientiousness and positive alcohol metacognitions about cognitive self-regulation were the only two significant predictors of weekly levels of alcohol use when controlling for gender. These findings show that being male, low on conscientiousness and high on positive alcohol metacognitions about cognitive self-regulation raises the risk for increased weekly levels of alcohol use in binge drinking university students. The implications of these findings are discussed. Copyright © 2011 Elsevier Ltd. All rights reserved.

Minimally refined biomass fuel. [carbohydrate-water-alcohol mixture

Energy Technology Data Exchange (ETDEWEB)

Pearson, R.K.; Hirschfeld, T.B.

1981-03-26

A minimally refined fluid composition, suitable as a fuel mixture and derived from biomass material, is comprised of one or more water-soluble carbohydrates such as sucrose, one or more alcohols having less than four carbons, and water. The carbohydrate provides the fuel source; water-solubilizes the carbohydrate; and the alcohol aids in the combustion of the carbohydrate and reduces the viscosity of the carbohydrate/water solution. Because less energy is required to obtain the carbohydrate from the raw biomass than alcohol, an overall energy savings is realized compared to fuels employing alcohol as the primary fuel.

Preclinical work suggests that the metabotropic glutamate receptor subtype 5 (mGlu5) may represent a novel target to treat neuropsychiatric disorders, including alcohol use disorder and obesity. The goal of this first-in-man study was to evaluate the safety, tolerability and pharmacokinetics (PK) of GET 73 (PubChem SID: 329974174), a novel mGluR5 negative allosteric modulator. This was a double-blind, placebo-controlled, ascending dose, Phase I study conducted in healthy male volunteers in two experiments. GET 73 was administered as single ascending doses (N=48; Experiment 1; 10, 30, 100, 300, 450, 600-mg) or multiple ascending doses (N=32; Experiment 2; 100, 300, 450, 450-mg twice a day). Primary endpoints were the incidence of adverse events (AEs) among drug conditions and drug tolerability. The secondary endpoints were the PK parameters of GET 73 and its metabolite MET 2. Single GET 73 doses of up to 600-mg and repeated ascending doses of up to 450-mg twice/day were safe and well-tolerated. There were no serious or severe AEs. All AEs were mild or moderate in severity. Total GET 73 exposure increased with each increased GET 73 dose. A dose-related increase in mean maximum plasma drug concentration was observed after repeated dosing. Maximum plasma drug concentrations occurred between 0.5 and 2.05h after administration in all groups for both single and repeated doses. This first-in-human study indicates that GET 73, as single or multiple ascending doses, is safe and well-tolerated when administered to healthy male volunteers. Copyright © 2017 Elsevier B.V.

Alcohol advertising correlates with consumption, particularly in young people. We studied the evolution of the amounts spent on alcoholic beverages advertising and on advertising as a whole in conventional media in Spain during the period 1995-2005. We analyzed the amounts spent on advertising in total and on alcoholic beverages advertising by studying the annual INFOADEX Survey on Advertising Investment in Spain in conventional media (TV, radio, the press, billboards and Internet). The results were subdivided into the periods 1995-2000 and 2001-2005. In the period 1995-2000 there was an increase (Delta) in alcoholic beverages advertising expenditure, from 268 to 347 million euro (Delta=29.5%), but a decrease in its percentage of advertising as a whole (from 7.6% to 6.1%). In the period 2001-2005 there was a rise in alcohol advertising expenditure from 145 to 186 million euro(Delta=28.0%), and also in its percentage of total advertising (from 2.7% to 2.8%). In 2001-2005, spending by Regional governments on preventive advertising increased from 22 to 52 million euro (Delta=136%). Alcohol advertising expenditure remains high in Spain, with young people as a primary target. In contrast, there is only modest investment in preventive advertising. Regulatory measures are necessary with a view to protecting populations especially susceptible to uncontrolled consumption.

Prenatal alcohol exposure can alter physical and behavioral development, leading to a range of fetal alcohol spectrum disorders. Despite warning labels, pregnant women continue to drink alcohol, creating a need to identify effective interventions to reduce the severity of alcohol's teratogenic effects. Choline is an essential nutrient that influences brain and behavioral development. Recent studies indicate that choline supplementation can reduce the teratogenic effects of developmental alcohol exposure. The present study examined whether choline supplementation during prenatal ethanol treatment could mitigate the adverse effects of ethanol on behavioral development. Pregnant Sprague-Dawley rats were intubated with 6 g/kg/day ethanol in a binge-like manner from gestational days 5-20; pair-fed and ad libitum chow controls were included. During treatment, subjects from each group were intubated with either 250 mg/kg/day choline chloride or vehicle. Spontaneous alternation, parallel bar motor coordination, Morris water maze, and spatial working memory were assessed in male and female offspring. Subjects prenatally exposed to alcohol exhibited delayed development of spontaneous alternation behavior and deficits on the working memory version of the Morris water maze during adulthood, effects that were mitigated with prenatal choline supplementation. Neither alcohol nor choline influenced performance on the motor coordination task. These data indicate that choline supplementation during prenatal alcohol exposure may reduce the severity of fetal alcohol effects, particularly on alterations in tasks that require behavioral flexibility. These findings have important implications for children of women who drink alcohol during pregnancy. © 2010 Wiley-Liss, Inc.

2016-01-01

A UK student survey examined the motivations for consuming energy drinks alone and mixed with alcohol, and aimed to determine whether the type of motive had a differential effect on overall alcohol consumption. The online survey (N = 1873) assessed alcohol consumption and motivations for consumption when mixed with energy drinks (AMED) and mixed with other non-alcoholic beverages (AMOB) using a within-subject design. The most frequent neutral motives reported for AMED consumption included "I like the taste" (66.5%), and "to celebrate a special occasion" (35.2%). 52.6% of AMED consumers reported consuming AMED for at least one of five negative motives, primarily "to get drunk" (45.6%). Despite these negative motives those students reported consuming significantly less alcohol and fewer negative alcohol-related consequences on AMED occasions compared to alcohol-only (AO) occasions. Although the motives for consuming AMED and AMOB were comparable, more participants reported consuming AMED "to celebrate a special occasion", "to get drunk", because they "received the drink from someone else" or "because others drink it as well". However, significantly more students reported consuming AMOB than AMED because "It feels like I can drink more alcohol". Alcohol consumption was significantly less on AMED occasions compared to AMOB occasions, and both occasions significantly less than AO occasions. The majority of reasons for consuming AMED relate to neutral motives. Although 52.6% of students reported one or more negative motives for AMED consumption (predominantly "to get drunk") this had no differential effect on total alcohol consumption. The differences in motives suggest AMED is consumed more to enjoy special occasions and as a group-bonding experience, however alcohol consumption is significantly lower on such occasions in comparison to when AMOB or AO are consumed.
