    A methodology to generate 2-thio- and 2-oxoimidazoles through an addition-cyclization-isomerization reaction of propargylcyanamides with thiol and alcohol nucleophiles is described. In general, the reaction sequence allows for the rapid formation of highly substituted 2-thio- and 2-oxoimidazoles in good to excellent yields.

    The first (thio)cyanate to iso(thio)cyanate rearrangements based on 2-fluoroallylic alcohols are presented. Long-chain 2-fluoroallylic alcohols were converted to corresponding N-unsubstituted carbamates by treatment with trichloroacetyl isocyanate. Dehydration using trifluoroacetic anhydride in the presence of triethylamine formed intermediate allylic cyanates, which immediately underwent sigmatropic rearrangement to fluorinated allyl isocyanates. Without isolation the latter delivered fluorinated ureas by addition of amines. The thiocyanate to isothiocyanate rearrangements started from the same fluorinated allylic alcohols, which were first converted to mesylates. Heating in THF with potassium thiocyanate led to fluorinated allyl isothiocyanates, via [3,3]-sigmatropic rearrangement of intermediate allyl thiocyanates. The formed products were further reacted with amines to fluorinated thioureas.

  7. Origin of the superior performance of (thio)squaramides over (thio)ureas in organocatalysis.

    Lu, Tongxiang; Wheeler, Steven E

    2013-11-04

    The Diels-Alder cycloaddition of anthracene and nitrostyrene catalyzed by the squaramide-derived aminocatalysts (Sq) recently reported by Jørgensen and co-workers (Angew. Chem. 2012, 124, 10417; Angew. Chem. Int. Ed. 2012, 51, 10271) has been studied by using modern tools of computational quantum chemistry. This catalyst is compared with analogous urea-, thiourea-, and thiosquaramide-derived aminocatalysts. Ultimately, a thiosquar-amide-derived catalyst is predicted to result in the lowest free-energy barrier, while retaining the same high degree of enantioselectivity as Sq. This stems in part from the superior hydrogen-bonding ability of thiosquaramides, compared to squaramides and (thio)ureas. We also examine the hydrogen-bonding ability of (thio)ureas and (thio)-squaramides in model complexes. In contrast to previous work, we show that aromaticity does not contribute significantly to the enhanced hydrogen-bonding interactions of squaramides. Overall, thiosquaramide, which has not been explored in the context of either organocatalysis or molecular recognition, is predicted to lead to strong, co-planar hydrogen bonds, and should serve as a potent hydrogen-bonding element in a myriad of applications.

    Wet scrubbing is the leading proven commercial post-combustion FGD technology available to meet the sulfur dioxide reductions required by the Clean Air Act Amendments. To reduce costs associated with wet FGD, Dravo Lime Company has developed the ThioClear process. ThioClear is an ex-situ forced oxidation magnesium-enhanced lime FGD process. ThioClear process differs from the conventional magnesium-enhanced lime process in that the recycle liquor has minimal suspended solids and the by-products are wallboard quality gypsum and magnesium hydroxide, an excellent reagent for water treatment. The process has demonstrated sulfur dioxide removal efficiencies of +95% in both a vertical spray scrubber tower and a horizontal absorber operating at gas velocities of 16 fps, respectively. This report details the optimization studies and associated economics from testing conducted at Dravo Lime Company`s pilot plant located at the Miami Fort Station of the Cincinnati Gas and Electric Company.

    1991-03-01

    We report the synthesis of four new 4-thio-5,8-dideazafolic acid analogues and a 4-(methylthio) analogue structurally related to the thymidylate synthase (TS) inhibitor N10-propargyl-5,8-dideazafolic acid. Three N10-propargyl-4-thio-5,8-dideazafolic acid analogues had C2 amino, hydrogen, and methyl substituents. A 4-thio and a 4-(methylthio) compound each with hydrogen at C2 and ethyl at N10 were also synthesized. In general, the synthetic route involved thionation of the appropriate 4-oxoquinazoline; the sulfur thus introduced was then protected by methylation. Further protection with a pivaloyl group was required for the quinazoline bearing a 2-amino substituent. The protected quinazolines were treated with N-bromosuccinimide and the resulting 6-(bromomethyl) compounds were then coupled to the appropriate N-monoalkylated diethyl N-(4-aminobenzoyl)-L-glutamate in N,N-dimethylacetamide with calcium carbonate as base. The 4-thio-5,8-dideazafolic acids were obtained by removal of the methylthio group with sodium hydrosulfide, followed by deprotection of the carboxyl groups with cold dilute alkali. For the compound containing a pivaloyl protecting group, hot dilute alkali was used. To obtain the 5,8-dideazafolic acid containing a 4-(methylthio) substituent, the corresponding diester was treated with lithium hydroxide which selectively deprotected the carboxyl groups. The five compounds were tested as inhibitors of L1210 TS. It was found that replacement of the 4-oxygen of the quinazoline moiety by sulfur did not alter the TS inhibition. However, the introduction of a methylthio substituent at position 4 severely impaired TS inhibition. All 4-thio compounds were less cytotoxic to L1210 cells in culture than their 4-oxo counterparts.

    Full Text Available Per-O-acetyl-5-thio-DL-mannose was synthesized from petrochemicals in six steps and 9% overall yield. It was then derivatized into glycosyl trichloroacetimidate and subjected to glycosidation reaction with a mannosyl acceptor to give a separatable mixture of disaccharides with 5-thio-D- and L-mannosides. This is the first synthesis of an enantiomerically pure 5-thiosugar derivative from racemic chemicals. The D-glycoside was derivatized into methyl (5-thio-α-D-mannopyranosyl-2-O-α-D-mannopyranoside 6-phosphate as a potential inhibitor of a golgi α-1,2-mannosidase.

  16. The Quorum-Quenching Metallo-gamma-lactonase from Bacillus thuringiensis Exhibits a Leaving Group Thio Effect

    Lactone-hydrolyzing enzymes derived from some Bacillus species are capable of disrupting quorum sensing in bacteria that use N-acyl-L-homoserine lactones (AHLs) as intercellular signaling molecules. Despite the promise of these quorum-quenching enzymes as therapeutic and anti-biofouling agents, the ring opening mechanism and the role of metal ions in catalysis have not been elucidated. Labeling studies using {sup 18}O, {sup 2}H, and the AHL lactonase from Bacillus thuringiensis implicate an addition-elimination pathway for ring opening in which a solvent-derived oxygen is incorporated into the product carboxylate, identifying the alcohol as the leaving group. {sup 1}H NMR is used to show that metal binding is required to maintain proper folding. A thio effect is measured for hydrolysis of N-hexanoyl-L-homoserine lactone and the corresponding thiolactone by AHL lactonase disubstituted with alternative metal ions, including Mn{sup 2+}, Co{sup 2+}, Zn{sup 2+}, and Cd{sup 2+}. The magnitude of the thio effect on k{sub cat} values and the thiophilicity of the metal ion substitutions vary in parallel and are consistent with a kinetically significant interaction between the leaving group and the active site metal center during turnover. X-ray absorption spectroscopy confirms that dicobalt substitution does not result in large structural perturbations at the active site. Finally, substitution of the dinuclear metal site with Cd{sup 2+} results in a greatly enhanced catalyst that can hydrolyze AHLs 1600-24000-fold faster than other reported quorum-quenching enzymes.

    A method for quantification of total soluble protein-derived thiols in beer was developed based on the formation of fluorescent adducts with the maleimide compound ThioGlo 1. The problem of interference from fluorescent adducts of sulfite and ThioGlo 1 was solved by HPLC separation of the adducts followed by fluorescence detection. Using standard addition of GSH, a detection limit of 0.028 μM thiols was achieved. The application and validation of the method was demonstrated for beers with different color intensities, and the application range is in principle for any biological system containing thiols. However, the quantification of cysteine was complicated by a lower fluorescence response of its ThioGlo 1 adducts. Based on the studies of the responses of a series of cysteine-derived thiols and (1)H NMR studies of the structures of ThioGlo 1 adducts with GSH and cysteine, it was concluded that thiols with a neighboring free amino group yield ThioGlo 1 adducts with a reduced fluorescence intensity.

    Thio-dimethylarsinic acid (thio-DMA(V)) has recently been identified as human metabolite after exposure toward both the human carcinogen inorganic arsenic and arsenosugars, which are the major arsenical constituents of marine algae. This study aims to get further insight in the toxic modes of action of thio-DMA(V) in cultured human urothelial cells. Among others effects of thio-DMA(V) on eight cell death related endpoints, cell cycle distribution, genotoxicity, cellular bioavailability as well as for the first time its impact on DNA damage induced poly(ADP-ribosyl)ation were investigated and compared to effects induced by arsenite. The data indicate that thio-DMA(V) exerts its cellular toxicity in a similar or even lower concentration range, however most likely via different mechanisms, than arsenite. Most interestingly, thio-DMA(V) decreased damage-induced cellular poly(ADP-ribosyl)ation by 35,000-fold lower concentrations than arsenite. The inhibition of this essential DNA-damage induced and DNA-repair related signaling reaction might contribute to inorganic arsenic induced toxicity, at least in the bladder. Therefore, and also because thio-DMA(V) is to date by far the most toxic human metabolite identified after arsenosugar intake, thio-DMA(V) should contemporary be fully (also in vivo) toxicologically characterized, to assess risks to human health related to inorganic arsenic but especially arsenosugar dietary intake.

    This study aims at modifying dual-cure composite cements by adding thio-urethane oligomers to improve mechanical properties, especially fracture toughness, and reduce polymerization stress. Thiol-functionalized oligomers were synthesized by combining 1,3-bis(1-isocyanato-1-methylethyl)benzene with trimethylol-tris-3-mercaptopropionate, at 1:2 isocyanate:thiol. Oligomer was added at 0, 10 or 20 wt% to BisGMA-UDMA-TEGDMA (5:3:2, with 25 wt% silanated inorganic fillers) or to one commercial composite cement (Relyx Ultimate, 3M Espe). Near-IR was used to measure methacrylate conversion after photoactivation (700 mW/cm(2) × 60s) and after 72 h. Flexural strength and modulus, toughness, and fracture toughness were evaluated in three-point bending. Polymerization stress was measured with the Bioman. The microtensile bond strength of an indirect composite and a glass ceramic to dentin was also evaluated. Results were analyzed with analysis of variance and Tukey's test (α = 0.05). For BisGMA-UDMA-TEGDMA cements, conversion values were not affected by the addition of thio-urethanes. Flexural strength/modulus increased significantly for both oligomer concentrations, with a 3-fold increase in toughness at 20 wt%. Fracture toughness increased over 2-fold for the thio-urethane modified groups. Contraction stress was reduced by 40% to 50% with the addition of thio-urethanes. The addition of thio-urethane to the commercial cement led to similar flexural strength, toughness, and conversion at 72h compared to the control. Flexural modulus decreased for the 20 wt% group, due to the dilution of the overall filler volume, which also led to decreased stress. However, fracture toughness increased by up to 50%. The microtensile bond strength increased for the experimental composite cement with 20 wt% thio-urethane bonding for both an indirect composite and a glass ceramic. Novel dual-cured composite cements containing thio-urethanes showed increased toughness, fracture toughness and

    Platelet P2Y12 is an important adenosine diphosphate (ADP) receptor that is involved in agonist-induced platelet aggregation and is a valuable target for the development of anti-platelet drugs. Here we characterise the effects of thio analogues of uridine triphosphate (UTP) on ADP-induced platelet aggregation. Using human platelet-rich plasma, we demonstrate that UTP inhibits P2Y12 but not P2Y1 receptors and antagonises 10 µM ADP-induced platelet aggregation in a concentration-dependent manner with an IC50 value of ~250 µM. An eight-fold higher platelet inhibitory activity was observed with a 2-thio analogue of UTP (2S-UTP), with an IC50 of 30 µM. The 4-thio analogue (4S-UTP) with an IC50 of 7.5 µM was 33-fold more effective. A three-fold decrease in inhibitory activity, however, was observed by introducing an isobutyl group at the 4S- position. A complete loss of inhibition was observed with thio-modification of the γ phosphate of the sugar moiety, which yields an enzymatically stable analogue. The interaction of UTP analogues with P2Y12 receptor was verified by P2Y12 receptor binding and cyclic AMP (cAMP) assays. These novel data demonstrate for the first time that 2- and 4-thio analogues of UTP are potent P2Y12 receptor antagonists that may be useful for therapeutic intervention. PMID:28146050

    2011-01-01

    Full Text Available We synthesised and toxicologically characterised the arsenic metabolite thiodimethylarsinic acid (thio-DMAV. Successful synthesis of highly pure thio-DMAV was confirmed by state-of-the-art analytical techniques including H1-NMR, HPLC-FTMS, and HPLC-ICPMS. Toxicological characterization was carried out in comparison to arsenite and its well-known trivalent and pentavalent methylated metabolites. It comprised cellular bioavailability as well as different cytotoxicity and genotoxicity end points in cultured human A549 lung cells. Of all arsenicals investigated, thio-DMAV exerted the strongest cytotoxicity. Moreover, thio-DMAV did not induce DNA strand breaks and an increased induction of both micronuclei and multinucleated cells occurred only at beginning cytotoxic concentrations, indicating that thio-DMAV does not act via a genotoxic mode of action. Finally, to assess potential implications of thio-DMAV for human health, further mechanistic studies are urgently necessary to identify the toxic mode of action of this highly toxic, unusual pentavalent organic arsenical.

    Thio-urethanes were synthesized by combining 1,6-hexanediol-diissocyante (aliphatic) with pentaerythritol tetra-3-mercaptopropionate (PETMP) or 1,3-bis(1-isocyanato-1-methylethyl)benzene (aromatic) with trimethylol-tris-3-mercaptopropionate (TMP), at 1:2 isocyanate:thiol, leaving pendant thiols. Oligomers were added at 10-30 phr to BisGMA-UDMA-TEGDMA (5:3:2, BUT). 25 wt% silanated inorganic fillers were added. Commercial cement (Relyx Veneer, 3M-ESPE) was also evaluated with 10-20 phr of aromatic oligomer. Near-IR was used to follow methacrylate conversion (DC) and rate of polymerization (Rpmax). Mechanical properties were evaluated in three-point bending (ISO 4049) for flexural strength/modulus (FS/FM, and toughness), and notched specimens (ASTM Standard E399-90) for fracture toughness (KIC). Polymerization stress (PS) was measured on the Bioman. Volumetric shrinkage (VS, %) was measured with the bonded disk technique. Results were analyzed with ANOVA/Tukey's test (α=5%). In general terms, for BUT cements, conversion and mechanical properties in flexure increased for selected groups with the addition of thio-urethane oligomers. The aromatic versions resulted in greater FS/FM than aliphatic. Fracture toughness increased by two-fold in the experimental groups (from 1.17 ± 0.36 MPam(1/2) to around 3.23 ± 0.22 MPam(1/2)). Rpmax decreased with the addition of thio-urethanes, though the vitrification point was not statistically different from the control. VS and PS decreased with both oligomers. For the commercial cement, 20 phr of oligomer increased DC, vitrification, reduced Rpmax and also significantly increased KIC, and reduced PS and FM. Thio-urethane oligomers were shown to favorably modify conventional dimethacrylate networks. Significant reductions in polymerization stress were achieved at the same time conversion and fracture toughness increased.

    The crystal structure of the title compound, [Cd(NCS)2(C6H7NO)2] n is made up of Cd(2+) cations that are coordinated by three thio-cyanate ligands and three 4-(hy-droxy-meth-yl)pyridine ligands within distorted N4OS octa-hedra. The asymmetric unit consists of one Cd(2+) cation, two thio-cyanate anions and two 4-(hy-droxy-meth-yl)pyridine ligands in general positions. Two Cd(2+) cations are linked by two μ-1,3 N- and S-bonding thio-ycanate anions into dimers which are further linked into branched chains along [100] by two μ-1,6 N- and O-bonding 4-(hy-droxy-meth-yl)pyridine ligands. One additional N-bonded 4-(hy-droxy-meth-yl)pyridine ligand and one additional N-bonded thio-cyanate anion are only terminally bonded to the metal cation. Inter-chain O-H⋯S hydrogen bonds between the hy-droxy H atoms and one of the thio-cyanate S atoms connect the chains into a three-dimensional network.

    (RS)-2-Amino-3-(5-tert-butyl-3-hydroxy-4-isothiazolyl)propionic acid (thio-ATPA), a 3-isothiazolol analogue of (RS)-2-amino-3-(5-tert-butyl-3-hydroxy-4-isoxazolyl)propionic acid (ATPA), has previously been shown to be a relatively weak AMPA receptor agonist at native (S)-glutamic acid ((S)-Glu) receptors (EC(50)=14 microM), comparable in potency with ATPA (EC(50)=34 microM). Recent findings, that (S)-ATPA is a potent (EC(50)=0.48 microM) and selective agonist at homomerically expressed ionotropic GluR5, prompted us to resolve thio-ATPA using chiral chromatography and pharmacologically characterize the two enantiomers at native as well as cloned ionotropic glutamate receptors. The enantiomers, (S)- and (R)-thio-ATPA, were obtained in high enantiomeric excess, and their absolute stereochemistry established by an X-ray crystallographic analysis. Electrophysiologically, the two enantiomers were evaluated in the rat cortical wedge preparation, and the S-enantiomer was found to be an AMPA receptor agonist (EC(50)=8.7 microM) twice as potent as the racemate, whereas the R-enantiomer was devoid of activity. In accordance with this, (S)-thio-ATPA proved to be an agonist at homomerically expressed recombinant AMPA receptors (GluR1o, GluR3o, and GluR4o) with EC(50) values of 5, 32 and 20 microM, respectively, producing maximal steady state currents of 78--168% of those maximally evoked by kainic acid, and 120-1600% of those maximally evoked by (S)-ATPA. At homomerically expressed GluR5, (S)-thio-ATPA was found to be a potent agonist (EC(50)=0.10 microM), thus being approximately five times more potent than (S)-ATPA. (R)-Thio-ATPA induced saturating currents with an estimated EC(50) value of 10 microM, most likely due to a contamination with (S)-thio-ATPA. At heteromerically expressed GluR6+KA2 receptors, (S)-thio-ATPA showed relatively weak agonistic properties (EC(50)=4.9 microM). Thus, (S)-thio-ATPA has been shown to be a very potent agonist at GluR5, and may be a valuable

    Full Text Available Thiopeptides are a growing class of sulfur-rich, highly modified heterocyclic peptides that are mainly active against Gram-positive bacteria including various drug-resistant pathogens. Recent studies also reveal that many thiopeptides inhibit the proliferation of human cancer cells, further expanding their application potentials for clinical use. Thiopeptide biosynthesis shares a common paradigm, featuring a ribosomally synthesized precursor peptide and conserved posttranslational modifications, to afford a characteristic core system, but differs in tailoring to furnish individual members. Identification of new thiopeptide gene clusters, by taking advantage of increasing information of DNA sequences from bacteria, may facilitate new thiopeptide discovery and enrichment of the unique biosynthetic elements to produce novel drug leads by applying the principle of combinatorial biosynthesis. In this study, we have developed a web-based tool ThioFinder to rapidly identify thiopeptide biosynthetic gene cluster from DNA sequence using a profile Hidden Markov Model approach. Fifty-four new putative thiopeptide biosynthetic gene clusters were found in the sequenced bacterial genomes of previously unknown producing microorganisms. ThioFinder is fully supported by an open-access database ThioBase, which contains the sufficient information of the 99 known thiopeptides regarding the chemical structure, biological activity, producing organism, and biosynthetic gene (cluster along with the associated genome if available. The ThioFinder website offers researchers a unique resource and great flexibility for sequence analysis of thiopeptide biosynthetic gene clusters.

The molecular structure and detailed spectroscopic analysis of all three novel synthesized thiones derivatives have been performed using experimental techniques like 1H, 13C NMR, 2D (COSY, HSQC, DEPT-135 and DEPT-90) as well as theoretical calculations by density functional theory (DFT) using B3LYP and 6-311G + (d, p) basis set. The strength and nature of weak intramolecular interactions have been studied by atom in molecule (AIM) approach. Global reactivity descriptors have been computed to predict reactivity and reactive sites in the molecule.

    Summary Organocatalysis, now running its second decade of life, is being considered one of the main tools a synthetic chemist has to perform asymmetric catalysis. In this review the synthesis of six-membered rings, that contain multiple chiral centers, either by a ring closing process or by a functionalization reaction on an already existing six-membered ring, utilizing bifunctional (thio)ureas will be summarized. Initially, the use of primary amine-thioureas as organocatalysts for the above transformation is being discussed, followed by the examples employing secondary amine-thioureas. Finally, the use of tertiary amine-thioureas and miscellaneous examples are presented. PMID:27340441

    The emission properties of some aza-stilbenes (2-, 3- and 4-styrylpyridine) and thio-stilbenes [2- and 3-styrylthiophene and 1,2-di-(3-thienyl)ethene]have been investigated after inclusion in commercial (NaY) and cation-exchanged (TlY) faujasite zeolites to get information on the triplet properties through population of the T{sub 1} state induced by the heavy atom effect. The fluorescence properties in NaY and TlY were compared with those reported in solution. The phosphorescence spectra, observed in TlY at liquid nitrogen temperature, allowed the energy levels of the T{sub 1} states to be obtained. Phosphorescence lifetimes were also measured. Their comparison with the lifetime known for stilbene showed that the radiative decay is little affected by the heteroatoms. - Research highlights: {yields} The exchange of Na{sup +} with heavy Tl{sup +} cations in faujasite zeolites allowed the triplet properties of some hetero-stilbenes to be obtained. {yields} The absorption and fluorescence spectra in NaY and TlY were measured and compared with those in fluid solutions. {yields} The triplet energy levels and lifetimes of three aza-stilbenes and three thio-stilbenes in TlY were determined by measuring their phosphorescence emission at liquid nitrogen temperature.

  20. Impact of thio-urethane additive and filler type on light-transmission and depth of polymerization of dental composites.

    Faria-E-Silva, André Luis; Pfeifer, Carmem Silvia

    2017-08-11

    This study evaluated the effects of filler type and the addition of thio-urethane oligomers on light-transmission, polymerization kinetics and depth of cure of resin composites. BisGMA:UDMA:TEGMA (5:3:2wt%) were mixed with 0 (control) or 20wt% thio-urethane. Fillers with various sizes and refractive indices were included and refractive index (RI) measured. Unfilled resins were used as controls. The RIs of materials were measured before and after polymerization. The irradiance reaching the bottom of 3-mm thick specimens was measured during the polymerization. Degree of conversion to a depth of 5mm was mapped. An optical bench was used to simultaneously follow conversion and light transmission. The addition of thio-urethane increased the RI for all composites. As expected, RI also increased with conversion for all materials. The one exception was for the material filled with OX-50, in which the RI of the composite decreased with conversion. In this case, the irradiance at the bottom of the 3mm specimen was also the lowest among all groups. The addition of thio-urethanes had only minimal effect on light transmission within a filler type, but led to increased conversion in depth for all groups. The filler type itself had a greater effect on light transmission, and that correlated well with the degree of conversion. The effect of the thio-urethane addition on degree of conversion in depth was dependent on filler type. The additive can be tailored to improve the RI match with the filler to optimize light transmission in dental composites. Copyright © 2017 The Academy of Dental Materials. Published by Elsevier Ltd.

  1. Arsenobetaine and thio-arsenic species in marine macroalgae and herbivorous animals: Accumulated through trophic transfer or produced in situ?

    Science.gov (United States)

    Foster, Simon; Maher, William

    2016-11-01

    Arsenobetaine (AB) and thio-arsenoribosides were measured in common macroalgae species (8 phaeophyta, 4 rhodophyta and 2 chlorphyta), along the Australian south east coast line. As well, arsenic species profiles were measured for two common marine herbivores, the sea urchin Centrostephanus rodgersii and the fish Odax cyanomelas that graze on these macroalgae to understand if trophic transfer of these species would account for their presence in marine herbivores. AB was found in seven of the fourteen macroalgae species investigated but does not contributed significantly to any of the macroalgae arsenic content (0.01-1.2μg/g). AB was found in only two of the brown macroalgae and all the red and green macroalgae (with the exception of Corallina officinalis). Thio-arsenic species were found sporadically, but not in high concentrations in any of the macroalgae investigated. AB present in macroalgae is likely to be associated with epiphytic organisms while thio-arsenoribosides are likely to be produced by decaying parts of damaged macroalgae. A laboratory feeding experiment in which the herbivorous gastropod, Austrocochlea constricta, was fed macroalgae containing thio-arsenoribosides for a 24hr period every three days showed that these are readily accumulated over a short period. Thio-arsenoribosides in herbivores are therefore probably obtained through trophic transfer. Some AB is also obtained through trophic transfer; however, the presence of trimethylated arsonioribosides, a hypothesized precursor of AB formation in herbivores, suggests that some AB is produced within herbivores from the transformation of arsenoribosides accumulated from their diet.

    A series of thio-substituted pyrimidine, benzoxazole, benzothiazole and triazole analogues were synthesized from Baylis-Hillman bromides in a clean and efficient way. The synthesized twenty new compounds were subjected to in vitro COX-1 and COX-2 inhibitory activity. Majority of compounds found to be highly selective COX-2 inhibitor. Seven compounds (16e, 16f, 16k, 16l, 16m, 16r and 16s) displayed anti-inflammatory activity at micromolar concentrations with IC50 values for COX-2 inhibition ranging from 2.93 to 5.34 μM compared to reference drug whose IC50 is 2.66 μM. All these seven compounds had very little COX-1 inhibition property and thus are suitable candidates for anti-inflammatory drugs with less gastrointestinal side effect. Copyright © 2014 Elsevier Ltd.

    Glibenclamide is widely used in the management of non-insulin dependent diabetes mellitus, but numerous risks limit its use in therapy. In the search for novel structures that are safer and more efficient than glibenclamide, we obtained new chemical analogs based on bioisosterism, through the treatment of benzenesulfonamide derivatives with isothiocyanates and isocyanates, affording (thio)ureas with good yield. We also verified the hypoglycemic activity, through an in vivo approach. Most of these synthesized compounds improved glucose tolerance, and the mechanism of action of the best compound (7) suggests that its effect is mediated by insulin secretion, while its hypoglycemic action is triggered by glucose uptake involving GLUT4 expression and translocation through PI-3K and PKA activity and active de novo protein synthesis in skeletal muscle. Taking all these factors together, sulfonylthiourea 7 acts as an insulin secretagogue and insulinomimetic agent on glucose homeostasis, and does not exhibit toxicity in acute treatment.

    To minimize patient suffering, the smallest possible volume of blood should be collected for diagnosis and disease monitoring. When estimating insulin secretion capacity and resistance to insulin in diabetes mellitus (DM), increasing insulin assay immunosensitivity would reduce the blood sample volume required for testing. Here we present an ultrasensitive ELISA coupled with thio-NAD cycling to measure immunoreactive insulin in blood serum. Only 5 μL of serum was required for testing, with a limit of detection (LOD) for the assay of 10(-16) moles/assay. Additional recovery tests confirmed this method can detect insulin in sera. Comparisons between a commercially available immunoreactive insulin kit and our ultrasensitive ELISA using the same commercially available reference demonstrated good data correlation, providing further evidence of assay accuracy. Together, these results demonstrate our ultrasensitive ELISA could be a powerful tool in the diagnosis and treatment of not only DM but also many other diseases in the future.

    We have carried out experimental investigation on binary ice mixture containing carbon disulfide (CS2) and ammonia (NH3) ices formed at 10 K. Icy films were formed in various combinations to investigate the reactivity of CS2 and NH3 molecules on cometary nucleus. In the case of NH3 ices, deposition carried out at 10 K was found to contain NH3 homo-dimers that was found to reorient upon annealing to 40 K. Phase transition was found to take place as the 10 K ice was warmed to higher temperatures and the phase transition temperature was found to be 5 K higher for the mixed ice in comparison to the layered deposits. Thermal processing of the mixed deposition of CS2sbnd NH3 ice was found to leave thio residue, which could be ammonium dithiocarbamate that was even found to be present at 340 K.

    Diverse functionalized representatives of (1-4)-S-thiodisaccharides, 6-9 were synthesized and assessed for cytotoxicity and apoptosis against human cancer cell lines (A549, LoVo, MCF-7 and HeLa). The FCP 6 was more active against MCF-7 cells (i.e., an estrogen-dependent breast cancer line), whereas other (1-4)-S-thiodisaccharides showed strongest activity against A549 cells (i.e., a lung adenocarcinoma line). We propose to use a concept of functional 'CARB-pharmacophores' when evaluating a potential for the compounds' general antineoplastic activity. Future studies will determine the reasons for cell-type specificity of these compounds. The thio-sugar motif appears to be a promising lead for future developments. Copyright © 2014 Elsevier Ltd.

    A simple efficacious topical treatment for cutaneous leishmaniasis (CL) is still an unresolved challenge. This study aimed to evaluate the efficacy of the topical use of thioxolone plus benzoxonium chloride (Thio-Ben) tincture in combination with cryotherapy in comparison with intralesional meglumine antimoniate (Glucantime) along with cryotherapy in treating anthroponotic CL (ACL). The study was conducted in Leishmaniasis Center in Dadbin Health Care Clinic, Kerman, Iran. Sixty-four CL lesions were randomly assigned to receive Thio-Ben plus cryotherapy (TC) (n = 32) or Glucantime plus cryotherapy (GC) (n = 32). Thio-Ben was used topically every other day and Glucantime was used intralesionally once a week for a maximum of 3 months. In both study groups, cryotherapy was administered using liquid nitrogen once every 2 weeks. Of 64 recruited lesions, 47 lesions completed the study protocol. Twenty lesions (91%) in TC group and 23 lesions (92%) in GC group showed complete cure. TC group showed faster clinical response. Pain, hypersensitivity reaction, dizziness, and nausea were only seen in GC group. This study showed that the topical use of Thio-Ben combined with cryotherapy has a good efficacy in treating ACL with the benefit that Thio-Ben has more patient compliance and less side effects than intralesional Glucantime.

    2-Thiocytosine (TC) and 2-thiouracil (TU) were subjected to hydrated electron (eaq(-)), formate radical (CO2˙(-)) and 2-hydroxypropan-2-yl radical ((CH3)2˙COH) reactions in aqueous medium. Transients were characterized by absorption spectroscopy and the experimental findings were rationalized by DFT calculations at LC-ωPBE and M06-2X levels using a 6-311+G(d,p) basis set and SMD solvation. In eaq(-) reactions, a ring N-atom protonated radical of TC and an exocyclic O-atom protonated radical of TU were observed via addition of eaq(-) and subsequent protonation by solvent molecules. However, two competing but simultaneous mechanisms are operative in CO2˙(-) reactions with TC and TU. The first one corresponds to formations of N(O)-atom protonated radicals (similar to eaq(-) reactions); the second mechanism led to 2 center-3 electron, sulfur-sulfur bonded neutral dimer radicals, TCdim˙ and TUdim˙. DFT calculations demonstrated that H-abstraction by CO2˙(-) from TC(TU) results in S-centered radical which upon combination with TC(TU) provide the dimer radical. In some cases, DFT energy profiles were further validated by CBS-QB3//M06-2X calculations. This is the first time report for a contradictory behavior in the mechanisms of eaq(-) and CO2˙(-) reactions with any pyrimidines or their thio analogues.

    Since the discovery of Dirac physics in graphene, research in 2D materials has exploded with the aim of finding new materials and harnessing their unique and tunable electronic and optical properties. The follow-on work on 2D dielectrics and semiconductors has led to the emergence and development of hexagonal boron nitride, black phosphorus, and transition metal disulfides. However, the spectrum of good insulating materials is still very narrow. Likewise, 2D materials exhibiting correlated phenomena such as superconductivity, magnetism, and ferroelectricity have yet to be developed or discovered. These properties will significantly enrich the spectrum of functional 2D materials, particularly in the case of high phase-transition temperatures. They will also advance a fascinating fundamental frontier of size and proximity effects on correlated ground states. Here, a broad family of layered metal thio(seleno)phosphate materials that are moderate- to wide-bandgap semiconductors with incipient ionic conductivity and a host of ferroic properties are reviewed. It is argued that this material class has the potential to merge the sought-after properties of complex oxides with electronic functions of 2D and quasi-2D electronic materials, as well as to create new avenues for both applied and fundamental materials research in structural and magnetic correlations. © 2017 WILEY-VCH Verlag GmbH & Co.

    Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy(ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM.

    The reaction of copper(I) iodide with N-acetyl­thio­morpholine (L, C6H11NOS) in aceto­nitrile results in a coordination polymer with composition [CuI(L)2]n. The CuI atom is coordinated by two S atoms and two I atoms, adopting a distorted tetra­hedral environment. The μ2-bridging mode of the I atoms gives rise to chains extending parallel to [010]. C—H⋯O hydrogen-bonding inter­actions between the chains lead to a three-dimensional network. PMID:28083135

    Serotonin transporters (SERT) are target-sites for commonly used antidepressants, such as fluoxetine, paroxetine, sertraline, and so on. Imaging of these sites in the living human brain may provide an important tool to evaluate the mechanisms of action as well as to monitor the treatment of depressed patients. Synthesis and characterization of an improved SERT imaging agent, ADAM (2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine)(7) was achieved. The new compound, ADAM(7), displayed an extremely potent binding affinity toward SERT (K{sub i}=0.013 nM, in membrane preparations of LLC-PK{sub 1}-cloned cell lines expressing the specific monoamine transporter). ADAM(7) also showed more than 1,000-fold selectivity for SERT over norepinephrine transporter (NET) and dopamine transporter (DAT) (K{sub i}=699 and 840 nM, for NET and DAT, respectively). The radiolabeled compound [{sup 125}I]ADAM(7) showed an excellent brain uptake in rats (1.41% dose at 2 min post intravenous [IV] injection), and consistently displayed the highest uptake (between 60-240 min post IV injection) in hypothalamus, a region with the highest density of SERT. The specific uptake of [{sup 125}I]ADAM(7) in the hypothalamus exhibited the highest target-to-nontarget ratio ([hypothalamus - cerebellum]/cerebellum was 3.97 at 120 min post IV injection). The preliminary imaging study of [{sup 123}I]ADAM in the brain of a baboon by single photon emission computed tomography (SPECT) at 180-240 min post IV injection indicated a specific uptake in midbrain region rich in SERT. These data suggest that the new ligand [{sup 123}I]ADAM(7) may be useful for SPECT imaging of SERT binding sites in the human brain.

    In this work, magnetic di-thio functionalized mesoporous silica nanoparticles (DT-MCM-41) were prepared by grafting dithiocarbamate groups within the channels of magnetic mesoporous silica nanocomposites. The functionalized nanoparticles exhibited proper magnetic behavior. They were easily separated from the aqueous solution by applying an external magnetic field. The results indicated that the functionalized nanoparticles had a potential for high-efficient removal of Hg(2+) in environmental samples. The maximum adsorption capacity of the sorbent was 538.9 mg g(-1), and it took about 10 min to achieve the equilibrium adsorption. The resulted adsorption capacity was higher than similar works for adsorption of mercury. It can be due to the presence of di-thio and amine active groups in the structure of sorbent. The special properties of MCM-41 like large surface area and high porosity also provided a facile accessibility of the mercury ions into the ligand sites. The complete removal of mercury ions was attained with dithiocarbamate groups in a wide range of mercury concentrations. The recovery studies were also applied for the river water, seawater, and wastewater samples, and the values were over of 97 %.

    The skin penetrating antioxidant cysteamine derivative of (-)-epicatechin as well as other thio conjugates were efficiently obtained with high yields from pine (Pinus pinaster) bark by simultaneous one pot extraction and depolymerization using water and cysteamine hydrochloride. The influence of the concentration of bark, acid, and cysteamine, as well as the reaction time on the total conversion, was studied. The total conversion into the epicatechin and catechin conjugates was as high as 47 g/kg pine bark with 1666 g cysteamine/kg bark and 28 g/kg with 166 g cysteamine/kg bark. A fast cleanup step by absorption/desorption on XAD-16 greatly facilitated further purification of the active major component. At a pilot scale, 4beta-(2-aminoethylthio)epicatechin (1) (conversion 263 g, purity 35% by reversed phase high-performance liquid chromatography/weight) was obtained from 17 kg of pine bark after simultaneous extraction/depolymerization followed by cleanup with the polymeric resin in approximately 10 h. The results show that pine (P. pinaster) bark is a suitable source of flavanols for the preparation of active thio derivatives. Conditions are given for the fast and efficient preparation of the conjugates.

    In the title compound, [Cu(NCS)(C3H9PS)] n , the thio-cyanate ions bind the Cu(I) atoms covalently, forming infinite -Cu-SCN-Cu- chains parallel to the a axis. Each Cu(I) atom is also coordinated to a tri-methyl-phosphine sulfide group via a Cu-S bond. Two crystallographically independent chains propagate in opposite directions, and are held together in a ribbon arrangement by long bonds between Cu(I) atoms in the first chain and thio-cyanate S atoms in the second, with Cu-S = 2.621 (1) Å. The geometry around the Cu(I) atoms in the first chain is distorted tetra-hedral, with angles involving the long Cu-S bond much less than ideal, and the S-Cu-N angle between the phosphine sulfide S atom and the thio-cyanate N atom opening out to 133.19 (9)°. Each Cu(I) atom in the second chain appears to be disordered between two positions 0.524 (4) Å apart, with occupancy factors of 0.647 (6) and 0.353 (6). The Cu(I) atom in the major site is in a distorted trigonal-planar configuration, with the S-Cu-N angle between the phosphine sulfide and the thio-cyanate N atom again opened out, to 137.01 (15)°. The Cu(I) atom in the minor site, however, forms in addition a long bond [Cu-S = 2.702 (5) Å] to the phosphine sulfide of the first chain, not the thio-cyanate S atom, to provide a further link between the chains.

    This study was to explore the prevalence of alcohol experiences and to identify the expectancy on the effects of alcohol and alcohol knowledge in early adolescents. The cross-sectional survey of 1854 students from seven middle schools in one district of Seoul was conducted by convenience sampling. Alcohol experience and early onset of alcohol use were measured by the Youth Risk Behavior Survey. Alcohol expectancy was measured by an Alcohol Effects Questionnaire. Over sixty five percent of adolescents reported that they had previous drinking experiences. The participants with no alcohol drinking experience had a lower level of alcohol knowledge than those with experience(t=2.73, p=.007). In expectancy on effects of alcohol, girls had a more positive alcohol expectation than boys(t=-2.54, p=.011). Alcohol knowledge negatively correlated with alcohol expectancy(r=-.40 p=.000). In regression of alcohol expectancy, gender and alcohol knowledge were significant predictors explaining 17%. The results support that alcohol expectancy is an important link with early drinking experiences and alcohol knowledge, focusing on the importance of gender differences. Therefore, an alcohol prevention program in early adolescence is needed and should be focused on multidimensionality of the alcohol expectancy with developmental and psychosocial factors for early adolescents.

    A novel 2-thio-6-oxo-1,6-dihydropyrimidine-containing inhibitor of human lactate dehydrogenase (LDH) was identified by high-throughput screening (IC50=8.1 μM). Biochemical, surface plasmon resonance, and saturation transfer difference NMR experiments indicated that the compound specifically associated with human LDHA in a manner that required simultaneous binding of the NADH co-factor. Structural variation of the screening hit resulted in significant improvements in LDHA biochemical inhibition activity (best IC50=0.48 μM). A crystal structure of an optimized compound bound to human LDHA was obtained and explained many of the observed structure-activity relationships. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Novel, water-soluble CdTe quantum dots (QDs) capped with β-cyclodextrin (β-CD) and ~ 4.0 nm in diameter were synthesized in aqueous solution, and characterized using transmission electron microscopy (TEM). A fluorescence-sensing system based on the photoinduced electron transfer (PET) of (mono-6-thio-β-CD)-CdTe QDs was then designed to measure the interaction of phenothiazine dyes [methylene blue (MB) and methylene green (MG)] with herring sperm DNA (hsDNA). This fluorescence-sensing system was based on a fluorescence "OFF-ON" mode. First, MB/MG adsorbed on the surface of (mono-6-thio-β-CD)-CdTe QDs effectively quenches the fluorescence of (mono-6-thio-β-CD)-CdTe QDs through PET. Then, addition of hsDNA restores the fluorescence intensity of (mono-6-thio-β-CD)-CdTe QDs, because hsDNA can bind with MB/MG and remove it from the as-prepared (mono-6-thio-β-CD)-CdTe QDs. In addition, detailed reaction mechanisms of the (mono-6-thio-β-CD)-CdTe QDs-MB/MG-hsDNA solution system were studied using optical methods, by comparison with the TGA-CdTe QDs-MB/MG-hsDNA solution system.

    Alcohol withdrawal is a common clinical condition that has a variety of complications and morbidities. The manifestations can range from mild agitation to withdrawal seizures and delirium tremens. The treatments for alcohol withdrawal include benzodiazepines, anticonvulsants, beta-blockers and antihypertensives. Although benzodiazepines are presently a first-line therapy, there is controversy regarding the efficacies of these medications compared with others. Treatment protocols often involve one of two contrasting approaches: symptom-triggered versus fixed-schedule dosing of benzodiazepines. We describe these protocols in our review and examine the data supporting symptom-triggered dosing as the preferred method for most patients in withdrawal.The Clinical Institute Withdrawal Assessment for Alcohol scoring system for alcohol withdrawal streamlines care, optimizes patient management, and is the best scale available for withdrawal assessment. Quality improvement implications for inpatient management of alcohol withdrawal include increasing training for signs of withdrawal and symptom recognition, adding new hospital protocols to employee curricula, and ensuring manageable patient-to-physician and patient-to-nurse ratios.

    The interaction of Cd2+ with uracil,2-thiouracil,4-thiouracil and 2,4-dithiouracil have been investigated by the density functional theory(DFT) calculations.For uracil and 2,4-dithiouracil,where the two basic sites are the same,Cd2+ attachment to the heteroatom at position 4 is preferred.However,for the systems where both types of basic centers,a carbonyl and a thiocarbonyl groups,are present,Cd2+ association with sulfur is favorable.The enhanced stability of these enolic and thiol forms comes from Cd2+ interaction with two basic sites simultaneously,which thereby triggers a significant aromatization of the ring.More significantly,the Cd2+ binding energy with uracil and its thio-derivatives is larger than the tautomerization barriers connecting the diketo-like forms with the corresponding enolic-like tautomers.Consequently,when associated with Cd2+,all tautomers are energetically accessible and should be observed in the gas phase.

    The asymmetric unit of the title compound, C16H22N2O2S, contains two crystallographically independent mol-ecules (A and B). In mol-ecule A, the cyclo-hexane ring is disordered over two orientations [occupancy ratio 0.841 (10):0.159 (10)]. In each mol-ecule, the central carbonyl thio-urea unit is nearly planar (r.m.s. deviations for all non-H atoms of 0.034 Å in mol-ecule A and 0.094 Å in mol-ecule B). In both mol-ecules, the cyclo-hexane ring adopts a chair conformation. The mean plane of the cyclo-hexane ring makes dihedral angles of 35.8 (4) (mol-ecule A) and 20.7 (3)° (mol-ecule B) with that of the benzene ring. Each mol-ecule features an intra-molecular N-H⋯O hydrogen bond, which closes an S(6) ring motif. In the crystal, mol-ecules are linked via pairs of weak N-H⋯S inter-actions, forming inversion dimers with an R 2 (2)(8) ring motif for both mol-ecules. The crystal structure also features weak C-H⋯π ring inter-actions.

    Full Text Available New derivatives of 7-aminocephalosporanic acid 1–8 were synthesized by acylation of the 7-amino group of the cephem nucleus with various arylidinimino-1,3,4-thiadiazole-thio(or dithio-acetic acid intermediates 3a–d and 5a–d, respectively, so the acyl side chains of these new cephalosporins contained a sulfide or disulfide bond. This unique combination of a Schiff base with the sulfide or disulfide bonds in the acyl side chain afforded new cephalosporins of reasonable potencies, some of which were found to possess moderate activities against the tested microorganisms. Their chemical structures were characterized by ¹H-NMR, IR spectroscopy and elemental microanalysis. Preliminary in vitro antimicrobial activities of the prepared cephalosporins were investigated using a panel of selected microorganisms. Results indicated that the newly synthesized cephalosporins containing disulfide bonds (compounds 5–8 exhibited better activities against Staphylococcus aureus and Escherichia coli. The cephalosporins cross-linked by a sulfide bond (compounds 1–4 showed a slight change in antimicrobial activities when compared with that of the reference cephalosporin (cephalexin.

The condensation reactions yield the corresponding Schiff Base ligands, HLa-Maf and H2Lb-Daf. The chelation of the ligands to metal ions occurs through the sulfur of the thiol group as well as the nitrogen atoms of the azomethine group of the ligands. HLa-Maf acts as monobasic bidentate or dibasic tetradentate, while H2Lb-Daf behaves as twice negatively cargend tetradentate ligand. The structures of these ligands were elucidated by elemental analysis, infrared, ultraviolet-visible spectra, as well as 1H NMR spectra. Reactions of the Schiff bases ligands with ruthenium(III), oxovanadium(IV) and dioxouranium(VI) afforded the corresponding transition metal complexes. The properties of the newly prepared complexes were analyse by elemental analyses, infrared, electronic spectra, 1H NMR as well as the magnetic susceptibility and conductivity measurement. The metal complexes exhibits different geometrical arrangements such as octahedral and square pyramidal coordination. Schiff base ligands and their metal complexes were tested against two pathogenic bacteria as Gram-positive and Gram-negative bacteria as well as one kind of fungi to study their biological activity. All the complexes exhibit antibacterial and antifungal activities against these organisms.

    The title compound, C12H17N3OS, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the benzene ring and the hydrazinecarbo-thio-amide group are 6.9 (4) and 37.2 (5)° in mol-ecules A and B, respectively. An intra-molecular O-H⋯N hydrogen bond is observed in each mol-ecule. This serves to maintain an approximately planar conformation for mol-ecule A, but leaves a significant twist between these two groups in mol-ecule B. In the crystal, a weak N-H⋯S inter-action is observed, forming inversion dimers among the B mol-ecules and resulting in an R 2 (2)(8) motif. These dimers are further inter-connected by weak N-H⋯O and C-H⋯O inter-molecular inter-actions, forming chains along [011].

    The complexes TpWO2X react with sulfiding agents such as B2S3 or P4S10 to give the oxothio- and bis(thio)tungsten(VI) complexes TpWOSX (X = Cl(-)) and TpWS2X [X = Cl(-), S2PPh2(-); Tp = hydrotris(3,5-dimethylpyrazol-1-yl)borate]. The reaction of TpWS2Cl with (i) PPh3 in pyridine and (ii) dimethyl sulfoxide affords TpWOSCl in good overall yield. The chloro complexes undergo metathesis with alkali metal salts to yield species of the type TpWOSX and TpWS2X [X = OPh(-), SPh(-), SePh(-), (-)-mentholate]. The diamagnetic complexes exhibit NMR spectra indicative of C(1) (TpWOSX) or C(s) (TpWS2X) symmetry and IR spectra consistent with terminal oxo and thio ligation (nu(W=O), 940-925 cm(-1); nu(W=S) or nu(WS2), 495-475 cm(-1)). Crystals of (R,S)-TpWOS[(-)-mentholate] are monoclinic, space group P2(1), with a = 11.983(2) A, b = 18.100(3) A, c = 13.859(3) A, beta = 91.60(2) degrees, V = 3004.6(8) A(3), and Z = 4. Crystals of TpWS2(OPh)-CH2Cl2 are orthorhombic, space group Pbca, with a = 16.961(4) A, b = 33.098(7) A, c = 9.555(2) A, V = 5364(2) A(3), and Z = 8. The mononuclear, distorted-octahedral tungsten centers are coordinated by a tridentate Tp ligand, an alkoxy or aryloxy ligand, and two terminal chalcogenide ligands. The average W=O and W=S distances are 1.726(7) and 2.125(2) A, respectively, and the O=W=S and S=W=S angles 102.9(3) and 102.9(1) degrees, respectively. The tungsten and sulfur X-ray absorption spectra of TpWOSCl and TpWS2Cl are consistent with the presence of terminal pi-bonded thio ligands in both complexes. The thio complexes generally undergo a reversible one-electron reduction at potentials significantly more positive than their oxo analogues. The chemical, spectroscopic, and electrochemical properties of the complexes are heavily influenced by the presence of W=S pi frontier orbitals.

    Thio(bisphenolato) complexes of the type [M2(mu-tbop-kappa3O,S,O)2Cl4] [M = Zr 1, Hf 2 and tbop = 2,2-thiobis{4-(1,1,3,3-tetramethyl-butyl)phenolate}] were prepared by HCl elimination from tbopH2 and MCl4. Substitution of the chlorides in 1 and 2 by 2,6-diisopropylphenolato groups (dipp) generates new compounds [M2(mu-tbop-kappa3O,S,O)2(dipp)4] (M = Zr 3, Hf 4). The structures of 1-4 were confirmed by NMR spectroscopy; complexes 3 and 4 were further investigated by X-ray crystallography. These studies showed 1-4 to be dimers either in the solid state or in solution and to have metal centers adopting distorted octahedral geometry. However treatment of MCl4 with [Al2(mu-OEt)2(tbop-kappa3O,S,O)2] or [Al2(mu-tbop-kappa3O,S,O)2Me2] gave heterotrinuclear complexes [M(tbop-kappa3O,S,O)2Cl2(mu-AlX2)2] (M = Zr, X = Cl 5, X = Me 7 and M = Hf, X = Cl 6, X = Me 8) for which the single-crystal X-ray diffraction analysis showed zirconium and hafnium centers to have eight-coordinate dodecahedral geometry. Complexes 1-6 after activation with aluminium alkyls and supporting on MgCl2 showed a lack of activity in the ethene polymerization process and moderate activity towards 1-hexene producing high molecular weight atactic poly(1-hexenes).

    The highly toxic methyl-, ethyl- and phenylmercury species that may exist in the three main anatomical parts - the adductor muscle, the mantle and the visceral mass - of bay scallops (Argopecten irradias) were quantitatively released by cupric chloride, zinc acetate, sodium chloride and hydrochloric acid (HCl) under ultrasonic extraction. After centrifugation, the mercury species in the supernatant were concentrated by thio (SH)-bearing chelating resins, eluted with HClO4 and HCl and extracted with toluene. Separation was achieved by capillary GC equipped with programmed temperatures, a constant nitrogen flow and detected by a micro-electron capture detector (μECD). Under optimised conditions, the LODs for methyl-, ethyl- and phenylmercury in bay scallop samples were 1.1, 0.65 and 0.80 ng g(-1), respectively. The maximum RSD for three replicate determinations of methyl-, ethyl- and phenylmercury in bay scallop samples were 13.7%, 14.0% and 11.2%, respectively. In the concentration range of 4-200 ng g(-1) in bay scallop samples, the calibration graphs were linear with correlation coefficients not less than 0.997. Recoveries for spiked samples were in the range of 92.7-103.5% (methylmercury), 87.5-108.3% (ethylmercury) and 91.6-106.0% (phenylmercury), respectively. The method was verified by the determination of methylmercury in a CRM GBW10029 (Total Mercury and Methyl Mercury in Fish Tissue), with results in good agreement with the certified values. Methylmercury - the only existing species in bay scallops - was successfully determined by the method.

    This article is designed to review the representations of alcoholism provided by members of an association of former alcoholics, namely Alcoholics Anonymous (AA), based on partial results from a qualitative survey conducted in the Sapopemba group of AA in a neighborhood on the outskirts of the city of Sao Paulo, Brazil. The article thus analyzes alcoholism from an emic perspective, i.e., how it is conceived and managed by those who acknowledge themselves as being "sick as alcoholics", how they explain the sickness, how they experience it, and how they endeavor to overcome it. The purpose is to present AA and its treatment strategy and to highlight the link made by the association by conceiving of alcoholism as a physical, moral, and spiritual illness.

    Eight rare earth metal (Ⅲ) complexes with 2-(((4,6-dimethyl)-2-pyrimidinyl)thio)-acetic acid, LnL3*nH2O [HL=2-(((4,6-dimethyl)-2-pyrimidinyl)thio)-acetic acid; Ln=La, Ce, Pr, Nd, Sm Eu, Gd, Tb; n=4 or 5], were prepared and characterized by elemental analysis, complexometric titration, thermal analysis, conductivity, IR and 1H-NMR. The results reveal that carboxyl group of the ligand coordinates with rare earth ions in bidentate mode after deprotonated. The water molecules exist as crystal water in the complexes. The anti-tumour activities of HL and some complexes were tested by both the MTT and SRB methods. The results show that the suppression ratios of some complexes against the tested tumour cells (HL-60 human leukemia cell lines, BGC-823 human gastric carcinoma cell lines, hela human cervix adenocarcinoma cell lines and Bel-7402 human hepatic carcinoma cell lines) are superior to HL.

    The human androgen receptor (AR) is a proven therapeutic target in prostate cancer. All current antiandrogens, such as Bicalutamide, Flutamide, Nilutamide, and Enzalutamide, target the buried hydrophobic androgen binding pocket of this protein. However, effective resistance mechanisms against these therapeutics exist such as mutations occurring at the target site. To overcome these limitations, the surface pocket of the AR called binding function 3 (BF3) was characterized as an alternative target for small molecule therapeutics. A number of AR inhibitors directly targeting the BF3 were previously identified by us ( J. Med. Chem. 2011 . 54 , 8563 ). In the current study, based on the prior results, we have developed structure-activity relationships that allowed designing a series of 2-((2-phenoxyethyl)thio)-1H-benzimidazole and 2-((2-phenoxyethyl)thio)-1H-indole as lead BF3 inhibitors. Some of the developed BF3 ligands demonstrated significant antiandrogen potency against LNCaP and Enzalutamide-resistant prostate cancer cell lines.

    This study demonstrates a one versus two-step synthesis of fluorescent gold quantum dots (F-AuQDs) and nano clusters (F-AuNCs) functionalized with thiolated organic linkers using reduction of gold precursor in N,N Prime -dimethylformamide in 1 h of reaction. The F-AuQDs and F-AuNCs show fluorescence emission at 425 {+-} 5 nm upon excitation at 345 {+-} 5 nm of wavelength, with good water solubility and stability. Five different thiolated organic binary linkers consisting of various functional groups including: carboxylic acid, hydroxyl, and aromatic amine, were conjugated with the F-AuQDs and F-AuNCs. The formation mechanism and functionalization of the F-AuQDs and F-AuNCs was characterized using UV-vis absorption spectra, UV-vis light, fluorescent emission spectra, pH, TEM, and FTIR. The fluorescence emission of the F-AuQDs and F-AuNCs is greatly dependent on the thio-linker. This novel one-step approach provides facile and fast synthesis of F-AuQDs and F-AuNCs over the two-step method, with less than 5 h of reaction and workup compared to more than 28 h of reaction for the two-step approach. These thio-linker functionalized F-AuQDs and F-AuNCs have a wide application in fluorescent labeling of biomolecules, optical devices, imaging, energy transfer, and biosensing.

    Full Text Available Alcohol dependence is a disabling condition that has a high prevalence, but in Europe only a small fraction of the people diagnosed with alcohol abuse and dependence are treated, representing the widest treatment gap, as compared with other mental disorders. Early diagnosis and monitoring of alcoholic liver disease (ALD is still insufficiently solved. Although ALD is the most common cause for liver disease in the Western world, it largely remains underestimated and underdiagnosed for many reasons. The recent introduction of non-invasive elastographic techniques such as transient elastography (TE has significantly improved the early diagnosis of alcoholic liver cirrhosis (ALC. As demonstrated in the literature, inflammation-associated liver stiffness (LS rapidly decreases during alcohol detoxification, and is also directly correlated to change in LS in both abstinent and relapsing patients. Newly published data show that LS could be used to monitor and validate hepatoprotective effects during nalmefene usage. Nalmefene is an opioid system modulator that diminishes the reinforcing effects of alcohol, helping the patient to reduce drinking. Three randomised, multicentre, double-blind, placebo-controlled, parallelgroup Phase III studies were designed to assess the efficacy and safety of nalmefene in reducing alcohol consumption. Patients with a high or very high drinking risk level (DRL at baseline and randomisation show a clinically significant effect from nalmefene treatment, which is generally well tolerated. Moreover, reduced alcohol consumption supported by nalmefene in combination with psychosocial support may indeed help to reduce the alcohol-related burden and the large treatment gap.

    Full Text Available The author briefly interprets the research – results, referring to the phenomenon of children of alcoholics, especially the psychological and psychopathological characteristics of children of alcoholics in adolescence and young adulthood. The author presents a screening study of adolescents. The sample contains 200 high school students at age 18. The aim of the survey was to discover the relationship between alcohol consumption of parents, PTSD - related psychopathological symptoms and reported life quality of their children. The study confirmed the hypothesis about a substantial correlation between high alcohol consumption of parents, higher psychopathological symptom - expression and lower reported life quality score of their children. Higher PTSD-related symptomatology in children of alcoholics is probably resulted by home violence, which is very often present in family of alcoholics. The article also evaluated the results regarding suicide ideation of children of alcoholics, which is definitely more frequent and more intense than in their peers living in non alcohol – dependent families.

    Klop, Boudewijn; do Rego, Ana Torres; Cabezas, Manuel Castro

    2013-08-01

    This study reviews recent developments concerning the effects of alcohol on plasma triglycerides. The focus will be on population, intervention and metabolic studies with respect to alcohol and plasma triglycerides. Alcohol consumption and fat ingestion are closely associated and stimulated by each other via hypothalamic signals and by an elevated cephalic response. A J-shaped relationship between alcohol intake and plasma triglycerides has been described. A normal body weight, polyphenols in red wine and specific polymorphisms of the apolipoprotein A-V and apolipoprotein C-III genes may protect against alcohol-associated hypertriglyceridemia. In contrast, obesity exaggerates alcohol-associated hypertriglyceridemia and therefore the risk of pancreatitis. High alcohol intake remains harmful since it is associated with elevated plasma triglycerides, but also with cardiovascular disease, alcoholic fatty liver disease and the development of pancreatitis. Alcohol-induced hypertriglyceridemia is due to increased very-low-density lipoprotein secretion, impaired lipolysis and increased free fatty acid fluxes from adipose tissue to the liver. However, light to moderate alcohol consumption may be associated with decreased plasma triglycerides, probably determined by the type of alcoholic beverage consumed, genetic polymorphisms and lifestyle factors. Nevertheless, patients should be advised to reduce or stop alcohol consumption in case of hypertriglyceridemia.

    Full Text Available New 1-thio-1,3-diene complexes of chromium(0, molybdenum(0, and tungsten(0 with the biden-tate bonding of unsaturated ligand to the metal’s core via the π-system of the C=C bond and sulfur lone electron pair of heterodiene are obtained. Quantum-chemical calculations reveal geometry, electron structure, and formation free energies of these complexes, as well as factors governing the coordination mode. Hydrophosphorylation of the complexes begins from the attack of H-dialkylphosphonate towards the thiocarbonyl group; the generated organometallic α-mercaptophosphonates subsequently undergo the mercaptophosphonate-thiolphospate and thiolphosphate-thionphosphate rearrangements with organ-ophosphorus compounds remaining bound to the metal’s core.

    T4 DNA ligase is one of the most commonly used enzymes for in vitro molecular research and a useful model for testing the ligation mechanism of ATP-dependent DNA ligation. To better understand the influence of phosphate group modifications in the ligation process, a series of ATP analogs were tested as cofactors. P-diastereomers of newly developed β,γ-hypo-ATPαS (thio) and β,γ-hypo-ATP (oxo) were synthesized and their activity was compared to ATPαS and their natural precursors. The evaluation of presented ATP analogs revealed the importance of the α-phosphate stereogenic center in ATPαS for the T4 DNA ligase activity and sheds new light on the interaction between ATP-dependent DNA ligases and cofactors.

    The structural, electronic, and spectroscopic properties of 4-methyl-5-((5-phenyl-1,3,4 oxadiazol-2-yl)thio)benzene-1,2-diol (MPOTB) have been carried out at ab initio and DFT levels. A detailed study of geometrical parameters, Infrared spectrum, chemical shifts (13C NMR, 1H NMR), and electronic properties of the title compound is presented. The correlation between the theoretical and the experimental 13C, and 1H chemical shifts of MPOTB were about 1.02-1.03 and 0.98-1.00, respectively. The electronic properties, such as molecular electrostatic potential, NBO atomic charges, HOMO and LUMO energies were performed at above levels. Rather high hardness of MPOTB introduces it as a stable molecule. As a result, the calculated findings were compared with the observed values and generally found to be in good agreement.

    Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

    Rapid excessive alcohol drinking frequently causes disturbance of consciousness due to head trauma, brain edema, hypoglycemia, hyponatremia, hepatic coma and so on, provoked by acute alcohol intoxication. Rapid differential diagnosis and management are extremely important to save a life. On the other hands, the chronic users of alcohol so called alcoholism has many kinds of physical diseases such as liver diseases (i.e., fatty liver, alcoholic hepatitis, alcoholic liver cirrhosis and miscellaneous liver disease), diabetes mellitus, injury to happen in drunkenness, pancreas disease (i.e., acute and chronic pancreatitis and deterioration of chronic pancreatitis), gastrontestinal diseases (i.e., gastroduodenal ulcer), and so on. Enough attention should be paid to above mentioned diseases, otherwise they would turn worse more with continuation and increase in quantity of the alcohol. It should be born in its mind that the excessive drinking becomes the weapon threatening life.

    Alcohol is a potent somnogen and one of the most commonly used "over the counter" sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to unravel the mechanism of alcohol-induced sleep disruptions. We have conducted a series of experiments using two different species, rats and mice, as animal models. We performed microdialysis, immunohistochemical, pharmacological, sleep deprivation and lesion studies which suggest that the sleep-promoting effects of alcohol may be mediated via alcohol's action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Since binge alcohol consumption is a highly prevalent pattern of alcohol consumption and disrupts sleep, we examined the effects of binge drinking on sleep-wakefulness. Our results suggest that disrupted sleep homeostasis may be the primary cause of sleep disruption observed following binge drinking. Finally, we have also shown that sleep disruptions observed during acute withdrawal, are caused due to impaired

    Full Text Available Alcohol exerts teratogenic effects in all the gestation times, with peculiar features in relationship to the trimester of pregnancy in which alcohol is assumed. Alcohol itself and its metabolites modify DNA synthesis, cellular division, cellular migration and the fetal development. The characteristic facies of feto-alcoholic syndrome (FAS-affected baby depends on the alcohol impact on skull facial development during the first trimester of pregnancy. In association there are cerebral damages with a strong defect of brain development up to the life incompatibility. Serious consequences on fetal health also depends on dangerous effects of alcohol exposure in the organogenesis of the heart, the bone, the kidney, sensorial organs, et al. It has been demonstrated that maternal binge drinking is a high factor risk of mental retardation and of delinquent behaviour. Unfortunately, a lower alcohol intake also exerts deleterious effects on fetal health. In several countries of the world there is a high alcohol use, and this habit is increased in the women. Therefore, correct information has to be given to avoid alcohol use by women in the preconceptional time and during the pregnancy. Preliminary results of a study performed by the authors show that over 80% of pregnant and puerperal women are not unaware that more than 2 glasses of alcohol/week ingested during pregnancy can create neurological abnormalities in the fetus. However, after the information provided on alcoholic fetopathy, all women are conscious of the damage caused by the use of alcohol to the fetus during pregnancy. This study confirms the need to provide detailed information on the negative effects of alcohol on fetal health. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Alcoholism and alcohol-associated organ injury is one of the major health problems worldwide. Alcohol may lead to an alteration in intermediary metabolism and the relation between alcohol intake and body weight is a paradox. The effect of alcohol intake on resting metabolic rate, assessed by indirect calorimetry, and lipid oxidation, is still controversial. Small quantities of ethanol seem to have no effect on body weight. Ingestion of moderate amounts may lead to an increase in body weight, via a lipid-oxidizing suppressive effect. Chronic intake of excessive amounts in alcoholics leads to a decrease in body weight, probably via increased lipid oxidation and energy expenditure. Chronic ethanol abuse alters lipid-soluble (vitamins A, D and E) and water-soluble (B-complex vitamins, vitamin C) vitamins status, and some trace elements status such as magnesium, selenium or zinc.

    Problematic use of alcohol configures an element of interest in the context of preventive interventions aimed to ensuring the performance of any work in safety conditions. To contrast the acute alcohol abuse in the workplace the existing legislation provides alcoholimeters controls and prohibition of recruitment and administration of alcohol. Recent legislation (D.Lgs. 81/08) establishes health surveillance for alcohol dependence and appears still incomplete and difficult to apply. Clinical diagnostic tools available to the physician for alcohol dependence identification are well-defined and recently improved thanks to new laboratory markers with high sensitivity and specificity (CDT) and self-administered questionnaires. In this contest we are awaiting for legislative action to specify conditions and procedures for inspections in the workplace in order to face the problem of alcohol dependence without excessive bureaucracy and with more attention to preventive aspects.

    Full Text Available Background: The association between alcohol and aggression has long been recognized, but the systematic research to understand the causal basis for this relationship and the processes that underlie it has only been undertaken in the past 25 years. In the article the most important mechanisms, by which alcohol affects behavior, are explained. Aggression in persons with alcohol dependence and the connection between antisocial (dissocial personality disorder, alcohol and aggression are described. In addition different forms of aggression or violence, that have been committed under the influence of alcohol, such as inter-partner violence, sexual assault, child abuse, crime and traffic accidents are described.Conclusions: The research findings can be used in the prevention and treatment of alcohol-related aggression.

    Full Text Available Observational studies have attributed a protective effect to alcohol consumption on the development of atherosclerosis and cardiovascular morbidity and mortality. Alcohol intake in the amount of one to two drinks per day results in an estimated 20-40% reduction in cardiovascular events. An additional protective effect, according to major cohort studies, has been attributed to wine, probably due to antioxidant effects and platelet antiaggregation agents. On the other hand, the influence of different patterns of alcohol consumption and environmental factors may explain a great part of the additional effect of wine. Protection may be mediated by modulation of other risk factors, because alcohol increases HDL-C, produces a biphasic response on blood pressure, and modulates the endothelial function, while it neither increases body weight nor impairs glucose-insulin homeostasis. Alcohol may also have a direct effect on atherogenesis. Despite these favorable effects, the current evidence is not enough to justify prescribing alcohol to prevent cardiovascular disease.

    Full Text Available For a long time, alcohol was thought to exert a general depressant effect on the central nervous system (CNS. However, currently the consensus is that specific regions of the brain are selectively vulnerable to the acute effects of alcohol. An alcohol-induced blackout is the classic example; the subject is temporarily unable to form new long-term memories while relatively maintaining other skills such as talking or even driving. A recent study showed that alcohol can cause retrograde memory impairment, that is, blackouts due to retrieval impairments as well as those due to deficits in encoding. Alcoholic blackouts may be complete (en bloc or partial (fragmentary depending on severity of memory impairment. In fragmentary blackouts, cueing often aids recall. Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol on learning and memory may result from alteration of the hippocampus and related structures on a cellular level. A rapid increase in blood alcohol concentration (BAC is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts, implying that genetic factors play a role in determining CNS vulnerability to the effects of alcohol. This factor may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual‟s alcohol expectancy; one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Extensive research on memory and learning as well as findings related to the acute effects of alcohol on the brain may elucidate the mechanisms and impact associated with the alcohol- induced blackout.

    Alcohol abuse has numerous adverse health and social consequences. The consumer response to changes in alcohol affordability is an important issue on alcohol policy debates. Studies from many countries have shown an inverse relationship between alcohol prices and alcohol consumption in the population. There are, however, suggestions that increasing the price of alcohol by rising taxes may have limited effect on alcohol-related problems, associated with long-term heavy drinking. The aim of the present study was to evaluate the relationship between alcohol affordability and alcohol-related mortality rates in post-Soviet Belarus. For this purpose trends in alcohol-related mortality rates (mortality from liver cirrhosis, pancreatitis, alcoholism and alcohol psychoses) and affordability of vodka between 1990 and 2010 were compared. The time series analysis revealed that 1% increase in vodka affordability is associated with an increase in liver cirrhosis mortality of 0,77%, an increase in pancreatitis mortality of 0.53%, an increase in mortality from alcoholism and alcohol psychoses of 0,70%. The major conclusion emerging from this study is that affordability of alcohol is one of the most important predictor of alcohol-related problems in a population. These findings provide additional evidence that decreasing in affordability of alcohol is an effective strategy for reducing alcohol consumption and alcohol-related harm.

    Full Text Available Atherosclerosis is manifested as coronary artery disease (CAD, ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day, especially red wine, may be allowed for those at risk for atherosclerosis complications.

    Chronic use of alcohol is considered to be a potential risk factor for the incidence of type 2 diabetes mellitus (T2DM), which causes insulin resistance and pancreatic β-cell dysfunction that is a prerequisite for the development of diabetes. However, alcohol consumption in diabetes has been controversial and more detailed information on the diabetogenic impact of alcohol seems warranted. Diabetes, especially T2DM, causes dysregulation of various metabolic processes, which includes a defect in the insulin-mediated glucose function of adipocytes, and an impaired insulin action in the liver. In addition, neurobiological profiles of alcoholism are linked to the effects of a disruption of glucose homeostasis and of insulin resistance, which are affected by altered appetite that regulates the peptides and neurotrophic factors. Since conditions, which precede the onset of diabetes that are associated with alcoholism is one of the crucial public problems, researches in efforts to prevent and treat diabetes with alcohol dependence, receives special clinical interest. Therefore, the purpose of this mini-review is to provide the recent progress and current theories in the interplay between alcoholism and diabetes. Further, the purpose of this study also includes summarizing the pathophysiological mechanisms in the neurobiology of alcoholism.

    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy.

    Diminished sexual functioning among individuals dependent upon alcohol has been assessed. Ninety-seven male patients entered the study, all inpatients as the unit for treatment of alcoholism and drug addiction (Villa 6) in Porirua Hospital, Porirua. The sexual ability of these patients before the development of alcoholism was also rated for the same items and this rating was used as a control. Of the 97 patients, 69 (71 percent) suffered from sexual dysfunction for a period more than 12 months prior to admission to hospital. The disturbances noted were diminished sexual desire (58 percent of patients), erectile impotence (16 percent), premature ejaculation (4 percent), ejaculatory in competence (22 percent). A high proportion of the alcoholics showed signs of sexual deviation-19 percent having performed sexual crimes and a further 28 percent having repeated thought of sexual crimes. The possible causes of alcohol induced sexual dysfunction are discussed.

    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.

    Full Text Available Aim: To determine the level of alcohol consumption in a selected group of adolescents. Design: A descriptive cross-sectional study. Methods: The data were obtained using a part of the standardized ESPAD questionnaire for assessing consumption of alcoholic beverages. The sample comprised 422 students from seven secondary schools of different types in the city of Ostrava. For statistical analysis, the chi-squared test and Fisher's exact test (for n ≤ 5 were used. The data were processed using Stata v. 10. Results: More than half of respondents first tried alcohol before the age of 15. The most frequent alcohol-related problems were unprotected sex, decreased school performance and problems with parents or friends. Incomplete families were found to be an important factor in adolescents preferring and more frequently drinking beer. Conclusion: The study confirmed results reported by the Europe-wide survey ESPAD, namely that adolescents start to drink alcohol as early as before they turn fifteen.

    Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of nerve cells) while neuronal loss from selected brain regions indicates permanent and irreversible damage. There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Recently, it has been shown that excitatory amino acid (EAA) neurotransmitters and homocysteine levels are elevated in patients who underwent withdrawal from alcohol. Furthermore, it has been found that homocysteine induces neuronal cell damage by stimulating NMDA receptors as well as by producing free radicals. Homocysteine neurotoxicity via overstimulation of N-methyl-D-aspartate receptors may contribute to the pathogenesis of both brain shrinkage and withdrawal seizures linked to alcoholism.

    The asymmetric unit of the title compound, [Rb2(P2S6)(C12H24O6)2]·2CH3CN, contains one half of an [Rb(18-crown-6)2]2[P2S6] unit and one aceto-nitrile solvent mol-ecule. The [Rb(18-crown-6)]2[P2S6] unit is completed by inversion symmetry. Its Rb(+) ion is situated near the centre of the macrocyclic cavity, but is displaced by 0.8972 (1) Å from the O atoms of the crown in the direction of the [P2S6](2-) moiety. The overall coordination number of the cation is eight, defined by the six crown ether O atoms and by two terminal S atoms of the [P2S6](2-) anion. The hexa-thio-metadiphosphate anion is built up from two tetra-hedral PS4 units joined together by a common edge. The crystal structure is characterized by alternating layers of [Rb(18-crown-6)]2[P2S6] and aceto-nitrile solvent mol-ecules stacked along [010].

    Even though nicotinic acid (niacin) appears to have beneficial effects on human lipid profiles, niacin-induced cutaneous vasodilatation called flushing limits its remedy to patient. GPR109A is activated by niacin and mediates the anti-lipolytic effects. Based on the hypothesis that β-arrestin signaling mediates niacin-induced flushing, but not its anti-lipolytic effect, we tried to find GPR109A agonists which selectively elicit Gi-protein-biased signaling devoid of β-arrestin internalization using a β-lactamase assay. We identified a 4-(phenyl)thio-1H-pyrazole as a novel scaffold for GPR109A agonist in a high throughput screen, which has no carboxylic acid moiety known to be important for binding. While 1-nicotinoyl derivatives (5a-g, 6a-e) induced β-arrestin recruitment, 1-(pyrazin-2-oyl) derivatives were found to play as G-protein-biased agonists without GPR109A receptor internalization. The activity of compound 5a (EC50 = 45 nM) was similar to niacin (EC50 = 52 nM) and MK-6892 (EC50 = 74 nM) on calcium mobilization assay, but its activity at 10 μM on β-arrestin recruitment were around two and five times weaker than niacin and MK-6892, respectively. The development of G-protein biased GPR109A ligands over β-arrestin pathway is attainable and might be important in differentiation of pharmacological efficacy.

  20. Effects of an ATP analogue, adenosine 5'-[α-thio]-triphosphate, on F1-ATPase rotary catalysis, torque generation, and inhibited intermediated formation.

    F1-ATPase (F1), an important rotary motor protein, converts the chemical energy of ATP hydrolysis into mechanical energy using rotary motion with extremely high efficiency. The energy-conversion mechanism for this molecular motor has been extensively clarified by previous studies, which indicate that the interactions between the catalytic residues and the β- and γ-phosphates of ATP are indispensable for efficient catalysis and torque generation. However, the role of α-phosphate is largely unknown. In this study, we observed the rotation of F1 fuelled with an ATP analogue, adenosine 5'-[α-thio]-triphosphate (ATPαS), in which the oxygen has been substituted with a sulfur ion to perturb the α-phosphate/F1 interactions. In doing so, we have revealed that ATPαS does not appear to have any impact on the kinetic properties of the motor or on torque generation compared to ATP. On the other hand, F1 was observed to lapse into the ADP-inhibited intermediate states when in the presence of ATPαS more severely than in the presence of ATP, suggesting that the α-phosphate group of ATP contributes to the avoidance of ADP-inhibited intermediate formation.

    The title compound, C17H18N2O2S2, synthesized via a condensation reaction between S-benzyl di-thio-carbazate and 3,4-di-meth-oxy-benzaldehyde, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an L-shape but differ in the orientation of the benzyl ring with respect to the 3,4-di-meth-oxy-benzyl-idine ring, this dihedral angle is 65.59 (8)° in mol-ecule A and 73.10 (8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, forming dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H⋯O hydrogen bonds, giving inversion dimers of dimers. These units are linked by C-H⋯π inter-actions, forming ribbons propagating in the [100] direction.

    Two organic compounds - 3-thiolanespiro-5‧-hydantoin, 4-thio-1H-tetrahydropyranespiro-5‧-hydantoin and four new Pt(II) and Pt(IV) complexes with general formulas cis-[Pt(L)2Cl2] and cis-[Pt(L)2Cl4] were synthesized. The obtained compounds were characterized by elemental analysis, IR, 1H, 13C NMR spectroscopy. The hybrid DFT calculations were used for optimization of the structure geometries of the ligand (L1) and its Pt(II) complex (1). The calculated structural parameters such as bond lengths and angles are in good agreement with the experimental data for similar hydantoins and their platinum complexes. The obtained results showed that the geometry of the complex (1) is plane square and the bounding of the L1 with platinum ion is realized by sulfur atom from thiolane ring. The complexes were tested for cytotoxicity in vitro on four human tumor cell lines. The tested compounds exerted concentration-dependent cytotoxic effects against some of the tumor cell lines.

    In the title mol-ecular complex, [Ni(C3H5OS2)2(C5H4BrN)2], the Ni(2+) cation is located on a centre of inversion and has a distorted octa-hedral N2S4 environment defined by two chelating xanthate ligands and two monodentate pyridine ligands. The C-S bond lengths of the thio-carboxyl-ate group are indicative of a delocalized bond and the O-Csp (2) bond is considerably shorter than the O-Csp (3) bond, consistent with a significant contribution of one resonance form of the xanthate anion that features a formal C=O+ unit and a negative charge on each of the S atoms. The packing of the mol-ecules is stabilized by C-H⋯S and C-H⋯π inter-actions. In addition, π-π inter-actions between the pyridine rings [centroid-to-centroid distance = 3.797 (3) Å] are also present. In the crystal structure, mol-ecules are arranged in rows along [100], forming layers parallel to (010) and (001).

    Complex of copper(II) with 2-cyano-1-methyl-3-{2-{{(5-methylimidazol-4- yl)methyl}thio}ethyl)guanidin(xepamet) had been synthesized in 1 : 4 mole ratio of metal to the ligand in methanol. The complex was characterized by metal analysis, thermal gravimetry/differential thermal analyzer (TG/DTA), molar conductivity meter, (Fourier transform infrared spectroscopy) FT-IR, UV-Vis spectroscopy, and magnetic susceptibility balance. The molar conductivity measurement shows that the complex was 2: 1 for electrolyte and SO42- which was acting as a counter ion. The thermal analysis by Thermogravimetric (TG) indicates that the complex contained four molecules of H2O. The Infrared spectral data indicates that functional groups of (C=N) imidazole and (C-S) are coordinated to the center ion Cu2+. Magnetic moment measurement shows that the complex is paramagnetic with peff = 1.78 ± 0.01 BM. Electronic spectra of the complex show a broad band at 608 nm (16447.23 cm-1) are due to Eg→T2g transition. Based on those of characteristics, The complex formula was estimated as [Cu(xepamet)2]SO4.4H2O. The structure of [Cu(xepamet)2]SO4.4H2O complex is probably square planar.

Here, we assessed the efficacy of s{sup 4}UMP on JY cells. Treatment of JY cells with s{sup 4}UMP suppressed their colony forming activity and induced apoptosis; healthy human bone marrow granulocyte-macrophage progenitor cells were 14-fold less sensitive to the nucleotide. In vivo effectiveness of s{sup 4}UMP was determined using xenograft SCID mouse model. s{sup 4}UMP decreased the cell number and colony forming activity of the total cell content of the femur of SCID mice transplanted with JY cells without affecting the bone marrow of healthy mice. These results suggest that s{sup 4}UMP alone or in combination with other clinically approved anti-leukemic remedies should be further explored as a potential novel therapeutic agent.

    The aims of this study were: (i) to explore the structure-activity relationship of some new anti-inflammatory benzothieno[3,2-d]pyrimidin-4-one sulphonamide thio-derivatives 1-11; and (ii) to evaluate the possibility of using the most active compounds as fluorescent probes to determine tumours or their progression. Therefore, to know the precise mechanism by which these compounds interact with cyclooxygenase (COX)-2 enzyme, a molecular docking study was carried out; to assess spectroscopic characteristics, their absorption and emission properties were determined. The results demonstrated that some derivatives of benzothieno[3,2-d] pyrimidine exhibit interesting anti-inflammatory properties related to interactions with active sites of COX-2 and are fluorescent. The antipyrine-bearing compound 4 displayed high COX-2 affinity (ΔG = -9.4) and good fluorescent properties (Φfl = 0.032). Thus, some members of this new class of anti-inflammatory may be promising for fluorescence imaging of cancer cells that express the COX-2 enzyme. Further in vitro and in vivo studies are needed to confirm this hypothesis.

    The title compound, C9H8N2O2S3, crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209 Å) and are linked by an N-H⋯O hydrogen bond. In both mol-ecules, the thio-phene rings show orientational disorder, with occupancy factors of 0.6727 (17) and 0.3273 (17) for mol-ecule A, and 0.7916 (19) and 0.2084 (19) for mol-ecule B. The five-membered rings make an angle of 79.7 (2)° in mol-ecule A and an angle of 66.8 (2)° in mol-ecule B. In the crystal, chains of mol-ecules running along the a-axis direction are linked by N-H⋯O hydrogen bonds. The inter-action of adjacent chains through N-H⋯O hydrogen bonds leads to two types of ring structures containing four mol-ecules and described by the graph-set motifs R4(4)(18) and R4(2)(14).

    Bioactive scaffolds for tissue engineering call for demands on new materials which can enhance traditional biocompatibility requirements previously considered for clinical implantation. The current commercially available thermoplastic materials, such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(ε-caprolactone) (PCL) and their copolymers, have been used to fabricate scaffolds for regenerative medicine. However, these polymers have limitations including lacking of broadly tuning mechanical and degradable properties, and activation of specific cell-scaffold interactions, which limit their further application in tissue engineering. In the present study, electrospun scaffolds were successfully fabricated from a new class of block poly(butylene succinate)-based (PBS-based) copolyesters containing either butylene thiodiglycolate (BTDG) or butylene diglycolate (BDG) sequences. The polyesters displayed tunable mechanical properties and hydrolysis rate depending on the molecular architecture and on the kind of heteroatom introduced along the polymer backbone. To investigate their potential for skeletal regeneration, human mesenchymal stromal cells (hMSCs) were cultured on the scaffolds in basic, osteogenic and chondrogenic media. Our results demonstrated that PBS-based copolyesters containing thio-ether linkages (i.e. BTDG segments) were more favorable for chondrogenesis of hMSCs than those containing ether linkages (i.e. BDG sequences). In contrast, PBS-based copolyesters containing ether linkages showed enhanced mineralization. Therefore, these new functional scaffolds might hold potential for osteochondral tissue engineering applications.

    Gold nanoparticles (GNPs) (1-1,000 nm) modified by glucose have been considered to increase the toxicity of radiotherapy in human malignant cells. We report on the effect on lung-cancer cells, A549, of thio-glucose-bound gold nanoparticles (Glu-GNPs) with a size of 13 nm, combined with megavoltage (MV) X-ray. Viewed by transmission electron microscopy, Glu-GNPs were mainly distributed in the membrane-coated vesicles of A549 cells. The combination of Glu-GNPs with radiation resulted in a significant growth inhibition, compared with radiation alone (P < 0.05). Glu-GNPs enhanced radiation effect by increasing the ratio of A549 cells in the G2/M phase, and inducing more apoptosis. Furthermore, when combined with radiation, Glu-GNPs resulted in deregulation of Bcl-2 and upregulation of Bax and active caspase 3. Our results suggest that Glu-GNPs, as a new radiosensitizer, combined with radiation, can increase cytotoxicity on A549 cells not only by arresting the G2/M phase, but also by increasing apoptosis-probably via regulating the expression of Bcl-2 family of proteins and mitochondrial apoptotic pathway.

    Alcoholism is a chronic relapsing/remitting disease that is frequently unrecognized and untreated, in part because of the partial efficacy of treatment. Only approximately one-third of patients remain abstinent and one-third have fully relapsed 1 year after withdrawal from alcohol, with treated patients doing substantially better than untreated [1]. The partial effectiveness of strategies for prevention and treatment, and variation in clinical course and side effects, represent a challenge and an opportunity to better understand the neurobiology of addiction. The strong heritability of alcoholism suggests the existence of inherited functional variants of genes that alter the metabolism of alcohol and variants of other genes that alter the neurobiologies of reward, executive cognitive function, anxiety/dysphoria, and neuronal plasticity. Each of these neurobiologies has been identified as a critical domain in the addictions. Functional alleles that alter alcoholism-related intermediate phenotypes include common alcohol dehydrogenase 1B and aldehyde dehydrogenase 2 variants that cause the aversive flushing reaction; catechol-O-methyltransferase (COMT) Val158Met leading to differences in three aspects of neurobiology: executive cognitive function, stress/anxiety response, and opioid function; opioid receptor micro1 (OPRM1) Asn40Asp, which may serve as a gatekeeper molecule in the action of naltrexone, a drug used in alcoholism treatment; and HTTLPR, which alters serotonin transporter function and appears to affect stress response and anxiety/dysphoria, which are factors relevant to initial vulnerability, the process of addiction, and relapse.

  14. Fuel Class Higher Alcohols

    KAUST Repository

    2016-08-17

    This chapter focuses on the production and combustion of alcohol fuels with four or more carbon atoms, which we classify as higher alcohols. 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.

      Sociological studies into alcohol use seem to find it difficult to deal with the substance itself. Alcohol tends to be reduced to a symbol of a social process and in this way the sociological research loses sight of effects beyond the social. This paper suggests a new theoretical approach...... to the study of alcohol and teenagers' (romantic) relationships, inspired by actor-network theory (ANT). The central feature of ANT is to search for relationships, or rather networks, between all things relevant to the phenomenon. All material and semantic structures, things, persons, discourses, etc....... that influence a given situation are described as actants and are entered into the analysis. The aim of this paper is to propose a way of including materiality in sociological analyses of alcohol and to explore ways of using focus group interview material in ANT-inspired analysis.

    Mounting evidence over the last 40 years clearly indicates that alcoholism (alcohol dependence) is a disorder of the brain. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has taken significant steps to advance research into the neuroscience of alcohol. The Division of Neuroscience and Behavior (DNB) was formed within NIAAA in 2002 to oversee, fund, and direct all research areas that examine the effects of alcohol on the brain, the genetic underpinnings of alcohol dependence, the neuroadaptations resulting from excessive alcohol consumption, advanced behavioral models of the various stages of the addiction cycle, and preclinical medications development. This research portfolio has produced important discoveries in the etiology, treatment, and prevention of alcohol abuse and dependence. Several of these salient discoveries are highlighted and future areas of neuroscience research on alcohol are presented.

    2017-08-24

    In order to reduce harms from alcohol, evidence-based policies are to be introduced and sustained. To facilitate the dissemination of policies that reduce alcohol-related harms by documenting, comparing, and sharing information on effective alcohol polices related to restrictions on alcohol marketing and alcohol warning messaging in 10 Canadian provinces. Team members developed measurable indicators to assess policies on (a) restrictions on alcohol marketing, and (b) alcohol warning messaging. Indicators were peer-reviewed by three alcohol policy experts, refined, and data were collected, submitted for validation by provincial experts, and scored independently by two team members. The national average score was 52% for restrictions on marketing policies and 18% for alcohol warning message policies. Most provinces had marketing regulations that went beyond the federal guidelines with penalties for violating marketing regulations. The provincial liquor boards' web pages focused on product promotion, and there were few restrictions on sponsorship activities. No province has implemented alcohol warning labels, and Ontario was the sole province to have legislated warning signs at all points-of-sale. Most provinces provided a variety of warning signs to be displayed voluntarily at points-of-sale; however, the quality of messages varied. Conclusions/Importance: There is extensive alcohol marketing with comparatively few messages focused on the potential harms associated with alcohol. It is recommended that governments collaborate with multiple stakeholders to maximize the preventive impact of restrictions on alcohol marketing and advertising, and a broader implementation of alcohol warning messages.

    The Conceptual Level Analogies Test (CLAT), a well-constructed test of analogical reasoning, was given to groups of middle-aged male alcoholics and control subjects in two separate studies. As predicted, the alcoholics had lower CLAT scores than nonalcoholics in both studies. These results support the generalized-diffuse model of the neuropsychological effects of alcoholism. Contrary to prediction, alcoholics differed from control subjects as much on the easy analogies as they did on the hard analogies, which suggested that alcoholics differ both qualitatively and quantitatively from nonalcoholics in cognitive impairment. Finally, in two of three studies in our laboratory, familial alcoholics had significantly lower CLAT scores than nonfamilial alcoholics. These findings emphasize the importance of considering familial history of alcoholism when studying the neuropsychological functioning of alcoholics.

    A potentiometric sensor based on the 1-benzyl-3-(4-nitrophenyl) thio-urea was synthesized and tested as an ionophore in PVC based membrane sensor towards SCN - ions. This membrane exhibits a linear stable response over a wide concentration range (1.0 × 10''-5 to 1.0 × 10''-2 M) with a slope of -59.2 mV/dec., a detection limit of log[SCN''- ] = -5.05, and a selectivity coefficient for thiocyanate against perchlorate anion of logK{sub s}cn''pot = -0.133. The selectivity series of the membrane is as follows: SCN''- > ClO{sub 4}''- > I''- >NO{sub 3}''- >HSO{sub 3}''- > Cl''-HSO{sub '}'-''4 > F''- > CH{sub 3}COO''- > HCO''-''3 > Br''- > H{sub 2}PO{sub 4}''- > SO{sub 3}''-''2 > SO{sub 4}''-''2 > CO{sub 3}''-''2. The proposed electrode showed good selectivity and a good response for the SCN''- ion over a wide variety of other anions in pH 6.0 buffer solutions and has a fast response time of about < 5s.. The influences of the membrane by pH, ionophore, and plasticizer were studied.

    Full Text Available CONTEXT: The oropharynx microbiota plays an important role in the origin of infections, especially among alcoholics whose airway defenses are impaired. OBJECTIVE: To compare the normal oropharingeal flora in heavy alcohol drinker and non-alcoholics. PATIENTS: 117 persons, 58 heavy alcohol drinkers and 59 non-alcoholics. SETTING: Santa Casa de São Paulo Emergency Service. DESIGN: A blind prospective study. MAIN OUTCOMES MEASURES: Prevalence of aerobic and anaerobic bacteria, and fungi. RESULTS: The study of the oropharynx microbiota among heavy alcohol drinkers demonstrated the presence of anaerobic microorganisms in 84.5% of them, including: Bacteroides sp, Prevotella melaninogenica, Fusobacterium sp, Veilonella sp, Peptostreptococcus sp, Propionibacterium sp, Bifidobacterium sp and Clostridium sp, versus 30.5% (p<0.005 of non-alcoholics. Candida sp was present in 34.5% of heavy alcohol drinkers and 5.1% of non-alcoholics (p<0.005. Enterobacteria predominated among heavy alcohol drinkers (25% compared with non-alcoholics (5.5% only in the age group 14 to 34 years (p<0.05. CONCLUSION: Based upon these results, it was possible to conclude that the knowledge of the oropharynx microbiota among heavy drinkers and non-alcoholics has an important predictive value concerning probable etiologic agents of lower airway infections. Infections caused by anaerobic microorganisms and fungi should be taken into consideration during the choice of empirical therapy for heavy alcohol drinkers.

    Alternative transportation fuels, preferably from renewable sources, include alcohols with up to five or even more carbon atoms. They are considered promising because they can be derived from biological matter via established and new processes. In addition, many of their physical-chemical properties are compatible with the requirements of modern engines, which make them attractive either as replacements for fossil fuels or as fuel additives. Indeed, alcohol fuels have been used since the early years of automobile production, particularly in Brazil, where ethanol has a long history of use as an automobile fuel. Recently, increasing attention has been paid to the use of non-petroleum-based fuels made from biological sources, including alcohols (predominantly ethanol), as important liquid biofuels. Today, the ethanol fuel that is offered in the market is mainly made from sugar cane or corn. Its production as a first-generation biofuel, especially in North America, has been associated with publicly discussed drawbacks, such as reduction in the food supply, need for fertilization, extensive water usage, and other ecological concerns. More environmentally friendly processes are being considered to produce alcohols from inedible plants or plant parts on wasteland. While biofuel production and its use (especially ethanol and biodiesel) in internal combustion engines have been the focus of several recent reviews, a dedicated overview and summary of research on alcohol combustion chemistry is still lacking. Besides ethanol, many linear and branched members of the alcohol family, from methanol to hexanols, have been studied, with a particular emphasis on butanols. These fuels and their combustion properties, including their ignition, flame propagation, and extinction characteristics, their pyrolysis and oxidation reactions, and their potential to produce pollutant emissions have been intensively investigated in dedicated experiments on the laboratory and the engine scale

    Alcohol abuse and dependence represents a most serious health problem worldwide with major social, interpersonal and legal interpolations. Besides benzodiazepines, anticonvulsants are often used for the treatment of alcohol withdrawal symptoms. Anticonvulsants drugs are indicated for the treatment of alcohol withdrawal syndrome, alone or in combination with benzodiazepine treatments. In spite of the wide use, the exact role of the anticonvulsants for the treatment of alcohol withdrawal has not yet bee adequately assessed. To evaluate the effectiveness and safety of anticonvulsants in the treatment of alcohol withdrawal. We searched Cochrane Drugs and Alcohol Group' Register of Trials (December 2009), PubMed, EMBASE, CINAHL (1966 to December 2009), EconLIT (1969 to December 2009). Parallel searches on web sites of health technology assessment and related agencies, and their databases. Randomized controlled trials (RCTs) examining the effectiveness, safety and overall risk-benefit of anticonvulsants in comparison with a placebo or other pharmacological treatment. All patients were included regardless of age, gender, nationality, and outpatient or inpatient therapy. Two authors independently screened and extracted data from studies. Fifty-six studies, with a total of 4076 participants, met the inclusion criteria. Comparing anticonvulsants with placebo, no statistically significant differences for the six outcomes considered.Comparing anticonvulsant versus other drug, 19 outcomes considered, results favour anticonvulsants only in the comparison carbamazepine versus benzodiazepine (oxazepam and lorazepam) for alcohol withdrawal symptoms (CIWA-Ar score): 3 studies, 262 participants, MD -1.04 (-1.89 to -0.20), none of the other comparisons reached statistical significance.Comparing different anticonvulsants no statistically significant differences in the two outcomes considered.Comparing anticonvulsants plus other drugs versus other drugs (3 outcomes considered), results

  18. Stress, epigenetics, and alcoholism.

    Acute and chronic stressors have been associated with alterations in mood and increased anxiety that may eventually result in the development of stress-related psychiatric disorders. Stress and associated disorders, including anxiety, are key factors in the development of alcoholism because alcohol consumption can temporarily reduce the drinker's dysphoria. One molecule that may help mediate the relationship between stress and alcohol consumption is brain-derived neurotrophic factor (BDNF), a protein that regulates the structure and function of the sites where two nerve cells interact and exchange nerve signals (i.e., synapses) and which is involved in numerous physiological processes. Aberrant regulation of BDNF signaling and alterations in synapse activity (i.e., synaptic plasticity) have been associated with the pathophysiology of stress-related disorders and alcoholism. Mechanisms that contribute to the regulation of genetic information without modification of the DNA sequence (i.e., epigenetic mechanisms) may play a role in the complex control of BDNF signaling and synaptic plasticity-for example, by modifying the structure of the DNA-protein complexes (i.e., chromatin) that make up the chromosomes and thereby modulating the expression of certain genes. Studies regarding the epigenetic control of BDNF signaling and synaptic plasticity provide a promising direction to understand the mechanisms mediating the interaction between stress and alcoholism.

    Multiple lines of evidence strongly indicate that genetic factors contribute to the risk for alcohol use disorders (AUD). There is substantial heterogeneity in AUD, which complicates studies seeking to identify specific genetic factors. To identify these genetic effects, several different alcohol-related phenotypes have been analyzed, including diagnosis and quantitative measures related to AUDs. Study designs have used candidate gene analyses, genetic linkage studies, genomewide association studies (GWAS), and analyses of rare variants. Two genes that encode enzymes of alcohol metabolism have the strongest effect on AUD: aldehyde dehydrogenase 2 and alcohol dehydrogenase 1B each has strongly protective variants that reduce risk, with odds ratios approximately 0.2-0.4. A number of other genes important in AUD have been identified and replicated, including GABRA2 and alcohol dehydrogenases 1B and 4. GWAS have identified additional candidates. Rare variants are likely also to play a role; studies of these are just beginning. A multifaceted approach to gene identification, targeting both rare and common variations and assembling much larger datasets for meta-analyses, is critical for identifying the key genes and pathways important in AUD.

  20. Diabetes mellitus and alcohol.

    2004-01-01

    Alcohol influences glucose metabolism in several ways in diabetic patients as well as in non-diabetic patients. Since alcohol inhibits both gluconeogenesis and glycogenolysis, its acute intake without food may provoke hypoglycaemia, especially in cases of depleted glycogen stores and in combination with sulphonylurea. Consumed with a meal including carbohydrates, it is the preferred fuel, which may initially lead to somewhat higher blood glucose levels and hence an insulin response in type 2 diabetic patients. Depending on the nature of the carbohydrates in the meal, this may be followed by reactive hypoglycaemia. Moderate consumption of alcohol is associated with a reduced risk of atherosclerotic disorders. Diabetic patients benefit from this favourable effect as much as non-diabetic patients. Apart from effects on lipid metabolism, haemostatic balance and blood pressure, alcohol improves insulin sensitivity. This improvement of insulin sensitivity may also be responsible for the lower incidence of type 2 diabetes mellitus reported to be associated with light-to-moderate drinking. In case of moderate and sensible use, risks of disturbances in glycaemic control, weight and blood pressure are limited. Excessive intake of alcohol, however, may not only cause loss of metabolic control, but also annihilate the favourable effects on the cardiovascular system.

  1. Invertebrate models of alcoholism.

    For invertebrates to become useful models for understanding the genetic and physiological mechanisms of alcoholism related behaviors and the predisposition towards alcoholism, several general requirements must be fulfilled. The animal should encounter ethanol in its natural habitat, so that the central nervous system of the organism will have evolved mechanisms for responding to ethanol exposure. How the brain adapts to ethanol exposure depends on its access to ethanol, which can be regulated metabolically and/or by physical barriers. Therefore, a model organism should have metabolic enzymes for ethanol degradation similar to those found in humans. The neurons and supporting glial cells of the model organism that regulate behaviors affected by ethanol should share the molecular and physiological pathways found in humans, so that results can be compared. Finally, the use of invertebrate models should offer advantages over traditional model systems and should offer new insights into alcoholism-related behaviors. In this review we will summarize behavioral similarities and identified genes and mechanisms underlying ethanol-induced behaviors in invertebrates. This review mainly focuses on the use of the nematode Caenorhabditis elegans, the honey bee Apis mellifera and the fruit fly Drosophila melanogaster as model systems. We will discuss insights gained from those studies in conjunction with their vertebrate model counterparts and the implications for future research into alcoholism and alcohol-induced behaviors.

      Sociological studies into alcohol use seem to find it difficult to deal with the substance itself. Alcohol tends to be reduced to a symbol of a social process and in this way the sociological research loses sight of effects beyond the social. This paper suggests a new theoretical approach...... to the study of alcohol and teenagers' (romantic) relationships, inspired by actor-network theory (ANT). The central feature of ANT is to search for relationships, or rather networks, between all things relevant to the phenomenon. All material and semantic structures, things, persons, discourses, etc......'s development from being a non-drinker at the age of 14, to a heavy drinker at 16, the paper investigates how the actants brought out by young people themselves constitute different forms of agency.

    2008-01-01

    This longitudinal study examined the influence of alcohol advertising and promotions on the initiation of alcohol use. A measure of receptivity to alcohol marketing was developed from research about tobacco marketing. Recall and recognition of alcohol brand names were also examined. Data were obtained from in-class surveys of sixth, seventh, and eighth graders at baseline and 12-month follow-up. Participants who were classified as never drinkers at baseline (n = 1,080) comprised the analysis sample. Logistic regression models examined the association of advertising receptivity at baseline with any alcohol use and current drinking at follow-up, adjusting for multiple risk factors, including peer alcohol use, school performance, risk taking, and demographics. At baseline, 29% of never drinkers either owned or wanted to use an alcohol branded promotional item (high receptivity), 12% students named the brand of their favorite alcohol ad (moderate receptivity), and 59% were not receptive to alcohol marketing. Approximately 29% of adolescents reported any alcohol use at follow-up; 13% reported drinking at least 1 or 2 days in the past month. Never drinkers who reported high receptivity to alcohol marketing at baseline were 77% more likely to initiate drinking by follow-up than those were not receptive. Smaller increases in the odds of alcohol use at follow-up were associated with better recall and recognition of alcohol brand names at baseline. Alcohol advertising and promotions are associated with the uptake of drinking. Prevention programs may reduce adolescents' receptivity to alcohol marketing by limiting their exposure to alcohol ads and promotions and by increasing their skepticism about the sponsors' marketing tactics.

  8. Neuropathology of alcoholism.

    There are wide ranging effects of alcohol on the nervous system. Some interfere with physiological and neurochemical functions but ultimately structural damage occurs. During life one of the most impressive changes is brain shrinkage which can be visualized using neuroradiological imaging techniques. This article reviews the pathological explanations for brain shrinkage and addresses the question of the pathogenesis of the reversible component of this damage in relation to prolonged abstinence from alcohol. This shrinkage seems to relate to a loss of white matter. However, the cortex is also abnormal in that there is a loss of neurones from the frontal region. In this and other regions of the cortex examined there is shrinkage of the neuronal soma. This is reflected in a retraction of the neuronal dendritic arbor which plays a crucial role in cell-to-cell communication. In addition, the cerebellum appears to be vulnerable in alcoholic patients although it may well be that associated nutritional deficiencies play an important role. The Wernicke-Korsakoff syndrome is another important deficiency disorder which is seen most frequently in alcoholic patients. Two important population groups which are considered in this review are females and moderate ('social') drinkers. Females are thought to be more susceptible to the damaging effects of alcohol than males and this is examined in the light of the scant data available. Similarly, there are few neuropathological data on people who drink 30-80 grams of alcohol per day. In order to assess so-called 'safe levels of drinking' this is an important group to study.

    We simultaneously obtained blood samples in emergency patients for ethanol content from both antecubital fossae using an alcohol prep pad on one arm and a non-alcohol-containing germicidal solution on the other. Fifty patients with ethanol concentrations greater than zero were statistically analyzed. Twenty patients surveyed had no measurable alcohol level by either technique. There was no significant difference in the blood alcohol concentration obtained by either method of skin preparation in both groups (P less than .01). Blood alcohol concentration incidentally obtained in the emergency department by routine isopropyl alcohol skin preparation is an accurate laboratory parameter.

    To discuss the mechanism of action, the efficacy and the safety of Alcoholics Anonymous (AA) in the treatment of alcoholism. The published works on effective treatments for alcoholism is briefly reviewed and a prospective multidisciplinary follow-up of recovery from alcoholism in two community cohorts of adolescent males followed from 1940 until the present day is reviewed. The suggested mechanism of action of AA is that it employs four factors widely shown to be effective in relapse prevention in addictions: external supervision, substitute dependency, new caring relationships and increased spirituality. In addition, AA serendipitously follows the principles of cognitive behaviour therapy in relapse prevention. Alcoholics Anonymous appears equal to or superior to conventional treatments for alcoholism, and the skepticism of some professionals regarding AA as a first rank treatment for alcoholism would appear to be unwarranted. Alcoholics Anonymous is probably without serious side-effects.

    Alcohol, which is ubiquitous today, is a major health concern. Its use was already relatively high among the youngest respondents, peaked among young adults, and declined in older age groups. Alcohol is causally related to more than 60 different medical conditions. Overall, 4% of the global burden of disease is attributable to alcohol, which accounts for about as much death and disability globally as tobacco and hypertension. Alcohol also promotes the generation of reactive oxygen species (ROS) and/or interferes with the body's normal defense mechanisms against these compounds through numerous processes, particularly in the liver. Photobiomodulation (PBM) is a cell-specific effect of low intensity monochromatic light or low intensity laser irradiation (LIL) on biological systems. The cellular effects of both alcohol and LIL are ligand-independent so that PBM might rehabilitate alcohol induced dysfunction. The PBM on alcohol induced human neutrophil dysfunction and rat chronic atrophic gastritis, the laser acupuncture on alcohol addiction, and intravascular PBM on alcoholic coma of patients and rats have been observed. The endonasal PBM (EPBM) mediated by Yangming channel, autonomic nervous systems and blood cells is suggested to treat alcohol induced dysfunction in terms of EPBM phenomena, the mechanism of alcohol induced dysfunction and our biological information model of PBM. In our opinion, the therapeutic effects of PBM might also be achieved on alcoholic myopathy.

    2013-01-01

    Full Text Available This study explores types of alcohol and surrogates consumed, patterns of consumption, and reasons behind noncommercial alcohol consumption among alcohol-dependent patients in Belarus. The study was conducted in the Belarusian city Grodno in 2012 with 223 alcoholics admitted to narcological clinic using structured interviews. The results suggest that at least 20.2% of alcohol dependent patients regularly consume samogon and 11.8% of patients use surrogates, the most popular among which are medications with a high percentage of ethanol and industrial spirits. The belief that, according to quality criteria, samogon exceeds licensed vodka is the main motive for its consumption. The results of this study suggest the existence of the problem of consumption of noncommercial alcohol among alcohol dependent patients in Belarus.

  13. The risks associated with alcohol use and alcoholism.

    Rehm, Jürgen

    2011-01-01

    Alcohol consumption, particularly heavier drinking, is an important risk factor for many health problems and, thus, is a major contributor to the global burden of disease. In fact, alcohol is a necessary underlying cause for more than 30 conditions and a contributing factor to many more. The most common disease categories that are entirely or partly caused by alcohol consumption include infectious diseases, cancer, diabetes, neuropsychiatric diseases (including alcohol use disorders), cardiovascular disease, liver and pancreas disease, and unintentional and intentional injury. Knowledge of these disease risks has helped in the development of low-risk drinking guidelines. In addition to these disease risks that affect the drinker, alcohol consumption also can affect the health of others and cause social harm both to the drinker and to others, adding to the overall cost associated with alcohol consumption. These findings underscore the need to develop effective prevention efforts to reduce the pain and suffering, and the associated costs, resulting from excessive alcohol use.

  14. Hyperventilation, anxiety, craving for alcohol: a subacute alcohol withdrawal syndrome.

    Roelofs, S M

    1985-01-01

    Hyperventilation leading to respiratory alkalosis is part of the acute alcohol withdrawal syndrome On the basis of clinical observations and a literature review on withdrawal symptoms the following was hypothesized: (a) hyperventilation is also part of a subacute alcohol withdrawal syndrome and (b) hyperventilation appears together with anxiety and craving for alcohol. These hypotheses were tested in a sample of 37 male alcoholic inpatients, abstinent for periods from several weeks to 9 months. Subjects were administered a questionnaire dealing with drinking history and craving for alcohol during abstinence, the Spielberger Anxiety Inventory and a hyperventilation complaint checklist. Subjects' disposition to hyperventilation was assessed during a physiological measurement session. Results show that hyperventilatory symptoms, anxiety and craving for alcohol appear together. Moreover, the severity of hyperventilatory and anxiety symptomatology is positively correlated with the duration of physically dependent alcohol use but not with the duration of excessive drinking per se, irrespective of age. These results corroborate the hypotheses outlined before.

    We demonstrate the usefulness of surfactant coated CdSe quantum dots in bio-imaging applications after evaluating their steady state and time resolved emission responses. The surfactant coated QDs, with the respective sizes of ~14 nm and 10 nm are synthesized considering two different types of coating agents, namely, thio-glycolic acid (TGA) and sodium dodecyl sulfate (SDS). The steady state luminescence response is characterized by both near band edge (NBE) and defect-related emissions, but with a strong dependency on the nature of surfactant coating. Time resolved photoluminescence (TR-PL) studies have revealed bi-exponential characteristics with CdSe–TGA QDs exhibiting longer life time decay parameters than those of CdSe–SDS QDs. To be specific, the fast (τ{sub 1}) and the slow (τ{sub 2}) components are characterized by ~10 and 30 times larger values in the former than the latter case. In the FT-IR spectra, several stretching and bending vibrations are observed to be adequately influenced by the nature of surfactant coating. The availability of plentiful Na{sup +} counter ions around SDS coated QDs, as evident from the FT-IR spectroscopy studies, can also be responsible for obtaining reduced size of the QDs. In contrast, Raman active modes are apparently distinguishable in TGA coated QDs, with LO and TO mode positions significantly blue-shifted from the bulk values. While attributing to the intense defect mediated emission of TGA coated QDs, the effect of TGA coating presented a stronger fluorescence imaging capability over the SDS coated ones. A detailed assessment of fluorescent counts, as a basis of bio-imaging response, is being discussed on a comparative basis. - Highlights: • Fluorescent CdSe quantum dots are synthesized with two different kinds of surfactant coatings. • Time resolved photoluminescence (TR-PL) studies have revealed bi-exponential decay characteristics. • Both slow and fast decay parameters are found to be longer in CdSe QDs

  17. Genetic studies in alcohol research

    Karp, R.W. [National Institute on Alcohol Abuse and Alcoholism, Rockville, MD (United States)

    1994-12-15

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) supports research to elucidate the specific genetic factors, now largely unknown, which underlie susceptibility to alcoholism and its medical complications (including fetal alcohol syndrome). Because of the genetic complexity and heterogeneity of alcoholism, identification of the multiple underlying factors will require the development of new study designs and methods of analysis of data from human families. While techniques of genetic analysis of animal behavioral traits (e.g., targeted gene disruption, quantitative trait locus (QTL) mapping) are more powerful that those applicable to humans (e.g., linkage and allelic association studies), the validation of animal behaviors as models of aspects of human alcoholism has been problematic. Newly developed methods for mapping QTL influencing animal behavioral traits can not only permit analyses of human family data to be directly informed by the results of animal studies, but can also serve as a novel means of validating animal models of aspects of alcoholism. 55 refs.

    2013-05-01

    Full Text Available Background The frequent co-abuse of alcohol and tobacco may suggest that they share some common neurological mechanisms. For example, nicotine acts on Nicotinic acetylcholine receptors (nAChRs in the brain to release dopamine to sustain addiction. Might nAChRs be entwined with alcohol? Objectives This review summarizes recent studies on the relationship between alcohol and nAChRs, including the role of nAChRs in molecular biological studies, genetic studies and pharmacological studies on alcohol, which indicate that nAChRs have been potently modulated by alcohol. Methods We performed a cross-referenced literature search on biological, genetic and pharmacological studies of alcohol and nAChRs. Results Molecular biological and genetic studies indicated that nAChR (genes may be important in mediating alcohol intake, but we still lack substantial evidence about how it works. Pharmacological studies proved the correlation between nAChRs and alcohol intake, and the association between nicotine and alcohol at the nAChRs. The positive findings of varenicline (a partial agonist at the _4_2 nAChR, smoking-cessation pharmaceutical treatment for alcoholism, provides a new insight for treating co-abuse of these two substances. >Conclusions Molecular biological, genetic and pharmacological studies of alcohol at the nAChR level, provide a new sight for preventing and treating the co-abuse of alcohol and nicotine. Given the important role of nAChRs in nicotine dependence, the interaction between alcohol and nAChRs would provide a new insight in finding effective pharmacological treatments, in decreasing or stopping alcohol consumption and cigarette smoking concurrently.

    Underage drinking is a major problem in Australia and may be influenced by exposure to alcohol advertising. The objective of the present study was to collect data on 12-17 year old Australian adolescents' exposure to different types of alcohol advertising and examine the association between exposure to advertising and alcohol consumption. A cross-sectional survey of 1113 adolescents aged 12-17 years recruited with a variety of methods to gain a cross-section of participants across metropolitan, regional and rural New South Wales (including independent schools, mall intercepts and online). Participants answered a series of questions assessing adolescents' exposure to alcohol advertising across eight media (including television, Internet and point-of-sale). Alcohol consumption was assessed using three questions (initiation, recent consumption and frequency of consumption in the previous 12 months). The majority indicated that they had been exposed to alcohol advertisements on television, in newspapers and magazines, on the Internet, on billboards/posters and promotional materials and in bottleshops, bars and pubs; exposure to some of these types of alcohol advertisements was associated with increased alcohol consumption, with differences by age and gender. The results are consistent with studies from other countries and suggest that exposure to alcohol advertisements among Australian adolescents is strongly associated with drinking patterns. Given current high levels of drinking among Australian youth, these findings suggest the need to address the high levels of young people's exposure to alcohol advertising.

    Information was gathered on recognition and treatment of alcohol problems in the primary and secondary health sectors, the latter represented by a department of hepatology. The general practitioner finds in most cases (18/26, 69%) that it is relevant to advise about a patient's alcohol misuse...... on admission forms when the patient previously has been discharged from another department with this diagnosis. However, if the patient has not previously been hospitalised due to alcohol misuse, information on the diagnosis is only rarely (30/114, 26%) available. This difference is highly significant (P = 0.......0001). The case-recording hospital physician at admission recognises 73% of alcohol misusers who are admitted with a non-alcohol-related diagnosis. When the patient had been evaluated by both the admitting physician and the case-recording hospital physician, information on the alcohol problem occurred...

    2004-01-01

    The CERN Medical Service has observed an increase in the number of personnel suffering from alcohol-related problems in recent years, in spite of the implementation of stricter regulations concerning the consumption of alcohol on the site. The causes of alcohol-related problems are often complex and many-faceted. A family history of alcohol abuse can be a cofactor in excessive drinking. The effects on a person's work are not negligible and should not be ignored. "Alcohol and the work place" is the third part of a campaign designed to raise awareness of the risks of alcohol consumption, which has already dealt with "alcohol and health" and "alcohol and road safety".Many employers have taken steps to confront the problem, and CERN launched a campaign to help its employees suffering from alcohol-related problems over ten years ago. A standing SCC sub-group on the prevention of alcoholism has been set up and Operational Circular No. 8, which defines the role and responsibilities of all parties concerned in the m...

    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.

    2016-03-01

    © 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.

    Prepared at the request of US Senator Birch Bayh, Chairman of the National Alcohol Fuels Commission, this study may be best utilized as a guidebook and resource manual to foster the development of a statewide fuel alcohol plan. It examines sectors in Indiana which will impact or be impacted upon by the fuel alcohol industry. The study describes fuel alcohol technologies that could be pertinent to Indiana and also looks closely at how such a fuel alcohol industry may affect the economic and policy development of the State. Finally, the study presents options for Indiana, taking into account the national context of the developing fuel alcohol industry which, unlike many others, will be highly decentralized and more under the control of the lifeblood of our society - the agricultural community.

    Krishnan, Harish R; Sakharkar, Amul J; Teppen, Tara L; Berkel, Tiffani D M; Pandey, Subhash C

    2014-01-01

    Alcoholism is a complex psychiatric disorder that has a multifactorial etiology. Epigenetic mechanisms are uniquely capable of accounting for the multifactorial nature of the disease in that they are highly stable and are affected by environmental factors, including alcohol itself. Chromatin remodeling causes changes in gene expression in specific brain regions contributing to the endophenotypes of alcoholism such as tolerance and dependence. The epigenetic mechanisms that regulate changes in gene expression observed in addictive behaviors respond not only to alcohol exposure but also to comorbid psychopathology such as the presence of anxiety and stress. This review summarizes recent developments in epigenetic research that may play a role in alcoholism. We propose that pharmacologically manipulating epigenetic targets, as demonstrated in various preclinical models, hold great therapeutic potential in the treatment and prevention of alcoholism.

    Solomons, Hilary Denis

    2012-06-01

    Alcohol abuse is an important public health problem, with major implications in patients with a pre-existing liver pathology of viral origin. Hepatitis C, for example, is one of the diseases in which alcohol consumption can lead to the transition from a fairly benign outline to a potentially life-threatening liver disease. Alcohol abuse is usually identified on the basis of clinical judgment, alcoholism related questionnaires, laboratory tests and, more recently, biomarkers. Also on this list of tests, carbohydrate deficient transferrin (CDT) is widely available and useful for determining recent alcohol consumption, particularly when corroborated with elevation of other liver-associated enzymes. Clinicians should be aware of the indications and limitations of this test in order to better evaluate alcohol consumption in their patients.

    An overview with respect to the identification of patients with risky drinking, alcohol abuse or alcohol dependence is given. As a first step, a simple screening questionnaire should be used. Self-statements in standardized questionnaires are more valid than standard laboratory markers. A useful instrument is for example BASIC. In screening positive patients, an in-depth diagnosis is necessary and helps to distinguish between different forms of problematic alcohol use. Depending on the severity of the alcohol problem, brochures, internet-programs, counselling or referral to treatment services is helpful.

    The mononuclear mixed-ligand title complex, [CuCl(C7H7N3O2S)(C18H15P)2], displays a distorted tetra­hedral coordination sphere around the CuI atom, with two P atoms from two tri­phenyl­phosphane mol­ecules, one terminal S atom from a 1-(4-nitro­phen­yl)thio­urea mol­ecule and a chloride ion as ligands. An intra­molecular N—H⋯Cl hydrogen bond stabilizes the mol­ecular conformation [graph-set motif R 2 2(6)]. In the crystal, further N—H⋯Cl hydrogen bonds connect individual mol­ecules into zigzag chains parallel to [001]. The chains are linked by weak C—H⋯O hydrogen-bonding inter­actions into a three-dimensional network. PMID:28083132

  10. Acamprosate for alcohol dependence

    Directory of Open Access Journals (Sweden)

    Susanne Rösner

    Full Text Available BACKGROUND: Alcohol dependence is among the main leading health risk factors in most developed and developing countries. Therapeutic success of psychosocial programs for relapse prevention is moderate, but could potentially be increased by an adjuvant treatment with the glutamate antagonist acamprosate. OBJECTIVE: To determine the effectiveness and tolerability of acamprosate in comparison to placebo and other pharmacological agents. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: We searched the Cochrane Drugs and Alcohol Group (CDAG Specialized Register, PubMed, Embase and CINAHL in January 2009 and inquired manufacturers and researchers for unpublished trials. SELECTION CRITERIA: All double-blind randomised controlled trials (RCTs which compare the effects of acamprosate with placebo or active control on drinking-related outcomes. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data. Trial quality was assessed by one author and cross-checked by a second author. Individual patient data (IPD meta-analyses were used to verify the primary effectiveness outcomes. MAIN RESULTS: 24 RCTs with 6915 participants fulfilled the criteria of inclusion and were included in the review. Compared to placebo, acamprosate was shown to significantly reduce the risk of any drinking RR 0.86 (95% CI 0.81 to 0.91; NNT 9.09 (95% CI 6.66 to 14.28 and to significantly increase the cumulative abstinence duration MD 10.94 (95% CI 5.08 to 16.81, while secondary outcomes (gamma-glutamyltransferase, heavy drinking did not reach statistical significance. Diarrhea was the only side effect that was more frequently reported under acamprosate than placebo RD 0.11 (95% 0.09 to 0.13; NNTB 9.09 (95% CI 7.69 to 11.11. Effects of industry-sponsored trials RR 0.88 (95% 0.80 to 0.97 did not significantly differ from those of non-profit funded trials RR 0.88 (95% CI 0.81 to 0.96. In addition, the linear regression test did not indicate a significant risk of

  11. The alcohol withdrawal syndrome.

    2008-08-01

    The alcohol withdrawal syndrome (AWS) is a common management problem in hospital practice for neurologists, psychiatrists and general physicians alike. Although some patients have mild symptoms and may even be managed in the outpatient setting, others have more severe symptoms or a history of adverse outcomes that requires close inpatient supervision and benzodiazepine therapy. Many patients with AWS have multiple management issues (withdrawal symptoms, delirium tremens, the Wernicke-Korsakoff syndrome, seizures, depression, polysubstance abuse, electrolyte disturbances and liver disease), which requires a coordinated, multidisciplinary approach. Although AWS may be complex, careful evaluation and available treatments should ensure safe detoxification for most patients.

  12. Microstructure of neat alcohols

    CERN Document Server

    Perera, A; Zoranic, L; Perera, Aurelien; Sokolic, Franjo; Zoranic, Larisa

    2007-01-01

    Formation of microstructure in homogeneous associated liquids is analysed through the density-density pair correlation functions, both in direct and reciprocal space, as well as an effective local one-body density function. This is illustrated through a molecular dynamics study of two neat alcohols, namely methanol and \\emph{tert}-butanol, which have a rich microstructure: chain-like molecular association for the former and micelle-like for the latter. The relation to hydrogen bonding interaction is demonstrated. The apparent failure to find microstructure in water -a stronger hydrogen bonding liquid- with the same tools, is discussed.

  13. Pharmacologically induced alcohol craving in treatment seeking alcoholics correlates with alcoholism severity, but is insensitive to acamprosate

    2011-01-01

    Modulation of alcohol craving induced by challenge stimuli may predict the efficacy of new pharmacotherapies for alcoholism. We evaluated two pharmacological challenges, the α2-adrenergic antagonist yohimbine, which reinstates alcohol seeking in rats, and the serotonergic compound meta-chlorophenylpiperazine (mCPP), previously reported to increase alcohol craving in alcoholics. To assess the predictive validity of this approach, the approved alcoholism medication acamprosate was evaluated for...

    Alcohol addiction is a heterogeneous psychiatric disorder according to both phenotype and etiology. Difference in phenotype characteristics manifests in the manner the addiction arises, history of the alcoholic and history of drinking, comorbid disorders, and the phenomenon of abstinence difficulties. Concerning the etiology of alcoholism, the disease itself is considered to be a consequence of an interactive influence of the environment and genetic factors. Numerous researches conducted in the last decades discovered many aspects of the biochemical, cell and molecular bases of alcohol addiction, leading to a conclusion that alcoholism is, like many other addictions, a brain disease. By recognizing alcoholism as a disease which basically implies changes of the neurobiological mechanisms, as well as a clear genetic basis, it was supposed that the disease, having its basis solely in the symptomatology, is essentially heterogeneous. By trying to solve the problem of a clinically heterogeneous nature of the disease during the last fifty years, various sub-classifications of such patients have been suggested. According to Cloninger, subtypes of alcoholism differ also according to changes in the brain neurotransmission systems, i.e. it is supposed that patients suffering from alcoholism type 1 have a more pronounced dopaminergic transmission deficit, while dopaminergic transmission is not disturbed significantly in patients diagnosed with alcoholism type 2, who, however, have a significant lack of serotonergic transmission. In such a way, Cloninger actually presented the basis of the so-called neurobiological alcoholism model. Since he has connected differences in neurotransmission with differences in personality characteristics, this model is also known as the psychobiological model of alcoholism. The characteristic of alcoholism type 1 is avoiding damage (Harm Avoidance, HA) decreased dopamine transmission and increased serotonin transmission, while the significant

    BACKGROUND: To examine the relationship of alcohol consumption, alcohol use disorder and mortality. METHOD: A cohort of 4316 male former Vietnam-era US army personnel participating in telephone survey and medical examination in middle age (mean age 38.3 years) in 1985-1986 was used. Alcohol...... consumption was reported in face-to-face interview on medical history and information on DSM-III alcohol use disorder was obtained from structured psychiatric interview (using the Diagnostic Interview Schedule). Mortality hazard during 15 years of follow-up was assessed with Cox proportional hazard regression...... modeling. RESULT: A total of 4251 individuals participated in the psychiatric interview and the medical history interview. Of these 998 were abstainers, and for the remaining 3253 we calculated weekly average consumption and monthly frequency of binge drinking. A total of 1988 had alcohol dependence, abuse...

    In the present study, we have tested the cytotoxic and DNA damage activity of two novel bis-1,2,4 triazole derivatives, namely 1,4-bis[5-(5-mercapto-1,3,4-oxadiazol-2-yl-methyl)-thio-4-(p-tolyl)-1,2,4-triazol-3-yl]-butane (MNP-14) and 1,4-bis[5-(carbethoxy-methyl)-thio-4-(p-ethoxy phenyl) -1,2,4-triazol-3-yl]-butane (MNP-16). The effect of these molecules on cellular apoptosis was also determined. The in-vitro cytotoxicity was evaluated by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay as well as Trypan blue dye exclusion methods against human acute lymphoblastic leukemia (MOLT4) and lung cancer cells (A549). Our results showed that MNP-16 induced significant cytotoxicity (IC(50) of 3-5 μM) compared with MNP-14. The cytotoxicity induced by MNP-16 was time and concentration dependent. The cell cycle analysis by flow cytometry (fluorescence-activated cell sorting [FACS]) revealed that though there was a significant increase in the apoptotic population (sub-G(1) phase) with an increased concentration of MNP-14 and 16, there was no cell cycle arrest. Further, the comet assay results indicated considerable DNA strand breaks upon exposure to these compounds, thereby suggesting the possible mechanism of cytotoxicity induced by MNP-16. Hence, we have identified a novel molecule (MNP-16) which could be of great clinical relevance in cancer therapeutics.

    Baclofen shows potential for rapidly reducing symptoms of severe alcohol withdrawal syndrome (AWS) in people with alcoholism. Treatment with baclofen is easy to manage and rarely produces euphoria or other pleasant effects, or craving for the drug. This is an updated version of the original Cochrane Review published in 2015, Issue 4. To assess the efficacy and safety of baclofen for people with AWS. We updated our searches of the following databases to March 2017: the Cochrane Drugs and Alcohol Group Specialised Register, CENTRAL, PubMed, Embase, and CINAHL. We also searched registers of ongoing trials. We handsearched the references quoted in the identified trials, and sought information from researchers, pharmaceutical companies, and relevant trial authors about unpublished or uncompleted trials. We placed no restrictions on language. We included all randomised controlled clinical trials (RCTs) evaluating baclofen versus placebo or any other treatment for people with AWS. We excluded uncontrolled, non-randomised, or quasi-randomised trials. We included both parallel group and cross-over studies. We used standard methodological procedures expected by Cochrane. We included three RCTs with 141 randomised participants. We did not perform meta-analyses due to the different control interventions. For the comparison of baclofen and placebo (1 study, 31 participants), there was no significant difference in Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar) scores (very low quality evidence). For the comparison of baclofen and diazepam (1 study, 37 participants), there was no significant difference in CIWA-Ar scores (very low quality evidence), adverse events (risk difference (RD) 0.00, 95% confidence interval (CI) -0.10 to 0.10; very low quality evidence), dropouts (RD 0.00, 95% CI -0.10 to 0.10; very low quality evidence), and dropouts due to adverse events (RD 0.00, 95% CI -0.10 to 0.10; very low quality evidence).

    Full Text Available The aim of the article was to assess how the perception of alcohol craving, which is one of the symptoms of alcohol dependence, evolved, as well as how it was reflected in the diagnostic classifications. The purpose of this article was also a discussion of the models of the origins of craving, explaining the etiology of this phenomenon and the tools for measuring this concept. The concept of craving, defined as a strong need or compulsion to drink alcohol, functioned for many years, not only in the clinical practice but also as a concept inherently associated with alcohol dependence. However, among experts and researchers, there was no consensus about the etiology of this phenomenon and its development. Some emphasize the emotional – motivational aspect of it, while in the literature also its cognitive – behavioral nature is highlighted. Craving as a symptom has been recognized as a diagnostic criterion of alcohol dependence in the International Statistical Classification of Diseases and Related Health Problems – ICD 10. In the year 2013, it was also indicated as a symptom of disorder resulting from alcohol abuse in the Diagnostic and Statistical Manual of Mental Disorders – DSM 5. It seems to be significant also to discuss the tools used to measure craving, both in clinical trials and therapeutic practice, among them: the Alcohol Specific Role Play Test, Obsessive Compulsive Drinking Scale (OCDS Lubeck Craving Scale (LCRR and Alcohol Urge Questionnaire (AUQ.

    The number of Americans who are overweight or obese has reached epidemic proportions. Elevated weight is associated with health problems and increased medical expenditures. This paper analyzes Waves 1 and 2 of the National Epidemiological Survey of Alcohol and Related Conditions to investigate the role of alcohol consumption in weight gain. Alcohol is not only an addictive substance but also a high-calorie beverage that can interfere with metabolic function and cognitive processes. Because men and women differ in the type and amount of alcohol they consume, in the biological effects they experience as a result of alcohol consumption, and in the consequences they face as a result of obesity, we expect our results to differ by gender. We use first-difference models of body mass index (BMI) and alcohol consumption (frequency and intensity) to control for time-invariant unobservable factors that may influence changes in both alcohol use and weight status. Increasing frequency and intensity of alcohol use is associated with statistically significant yet quantitatively small weight gain for men but not for women. Moreover, the first-difference results are much smaller in magnitude and sometimes different in sign compared with the benchmark pooled cross-sectional estimates.

    2017-08-01

    Consumption of alcoholic beverages is widespread through much of the world, and significantly impacts human health and well-being. We sought to determine the contribution of orosensation ('taste') to several alcohol intake measures by examining general responsiveness to taste and somatosensory stimuli in a convenience sample of 435 adults recruited from six cohorts. Each cohort was divided into quantiles based on their responsiveness to sweet, sour, bitter, salty, umami, metallic, and astringent stimuli, and the resulting quantiles pooled for analysis (Kruskal-Wallis ANOVA). Responsiveness to bitter and astringent stimuli was associated in a non-linear fashion with intake of all alcoholic beverage types, with the highest consumption observed in middle quantiles. Sourness responsiveness tended to be inversely associated with all measures of alcohol consumption. Regardless of sensation, the most responsive quantiles tended to drink less, although sweetness showed little relationship between responsiveness and intake. For wine, increased umami and metallic responsiveness tended to predict lower total consumption and frequency. A limited examination of individuals who abstain from all alcohol indicated a tendency toward higher responsiveness than alcohol consumers to sweetness, sourness, bitterness, and saltiness (biserial correlation), suggesting that broadly-tuned orosensory responsiveness may be protective against alcohol use and possibly misuse. Overall, these findings confirm the importance of orosensory responsiveness in mediating consumption of alcohol, and indicate areas for further research. Copyright © 2017. Published by Elsevier Inc.

    2002-10-19

    Two homeless alcoholics, males aged 58 and 40 years, suffered from multiple health problems. Sleeping outdoors, excessive drinking and incompetence refrained them from seeking proper assistance. The patients were assessed on many occasions at primary care services provided in shelters in Amsterdam, at police stations and in the streets. They were also frequently admitted to shelter infirmaries, alcohol clinics and general hospitals. Despite substantial individual health damage, community costs and extreme care consumption, coercive treatment was not applied to prevent the death of the first patient and to stabilise the situation of the second. It is stated that a specific group such as homeless alcoholics can hardly be treated except during moments of crisis. Coercive treatment should be applicable in order to stabilise these patients so as to prevent early mortality among the alcoholic homeless with comparable health problems. Outreach primary care services for the alcoholic homeless should actively cooperate with addiction and mental health services in providing adequate care.

The literature could...... be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moderate to strong evidence of increased postoperative morbidity after surgical procedures on alcohol abusers. There is weak to moderate evidence of increased postoperative mortality, hospital stay, and re......-operation. The personal and economic consequences are tremendous.

    Several years ago, Cohen et al. (1958) demonstrated that under the influence of alcohol drivers became more risk prone, although their risk perception remained unchanged. Research shows that ambiguity aversion is to some extent positively correlated with risk aversion, though not very highly (Camerer and Weber, 1992). The question addressed by the present research is whether alcohol reduces ambiguity aversion. Our research was conducted in a natural setting (a restaurant bar), where customers with differing levels of alcohol intoxication were offered a choice between a risky and an ambiguous lottery. We found that alcohol reduced ambiguity aversion and that the effect occurred in men but not women. We interpret these findings in terms of the risk-as-value hypothesis, according to which, people in Western culture tend to value risk, and suggest that alcohol consumption triggers adherence to socially and culturally valued patterns of conduct different for men and women.

    Alcohol consumption is a global phenomenon, as is the resultant health, social and economic harm. The nature of these harms varies with different drinking patterns and with the societal and political responses to the burden of harm; nevertheless, alcohol-related chronic diseases have a major effect on health. Strong evidence exists for the effectiveness of different strategies to minimize this damage and those policies that target price, availability and marketing of alcohol come out best, whereas those using education and information are much less effective. However, these policies can be portrayed as anti-libertarian and so viewing them in the context of alcohol-related harm to those other than the drinker, such as the most vulnerable in society, is important. When this strategy is successful, as in Scotland, it has been possible to pass strong and effective legislation, such as for a minimum unit price for alcohol.

    1990-05-01

    The primary goal of the present article is to compare expectancy models with competing attitude models of alcohol use. First, several methodological issues in expectancy research were addressed, to more adequately compare the theoretical models. Study 1 examined the effect of possible self-report biases on associations among expectancy constructs and alcohol use. In Studies 2 and 3, the basic distinction between general factors of positive and negative alcohol expectancies was investigated in both cross-sectional and prospective models. Alternative predictions that were based on competing expectancy and attitude theories were evaluated primarily in Study 3. Results from these studies supported the validity of the expectancy constructs and the proposed distinctions among expectancy and attitude constructs-in terms of strong discriminant validity, absence of self-report bias, and differential prediction of alcohol use. Furthermore, the findings favored certain expectancy models over alternative attitude models of alcohol use, reaffirming the usefulness of the expectancy framework.

    Despite the fact that addiction has often been identified as an attachment disorder, empirical studies on this topic are rather scarce. In our study we explore attachment style (secure vs. insecure) in alcoholic inpatients and its relationship with perceived parenting and alcohol-related and psychiatric problems in a sample of 101 alcoholic inpatients (Belgium). Our results reveal that in comparison to the securely-attached group, insecurely-attached alcoholic inpatients perceived their mother as more controlling, reported more severe psychiatric problems in the European Addiction Severity Index, had higher scores on the Beck Depression Inventory, showed more schizotypal and depressive personality traits and had more difficulties with communicating emotions (alexithymia). We argue that it makes sense to differentiate alcoholic inpatients on the basis of attachment style and that both groups (secure/insecure) need different treatment approaches.

    The self-reported prevalence of alcohol use among U.S. college students decreased from 90.5% in 1980 to 79.2% in 2012. National efforts exist to reduce alcohol misuse among college students in the United States, yet little research addresses substance abuse among nursing students and even less addresses alcohol misuse. Alcohol misuse in nursing students may result in patient harm. This scoping study describes the state of the science of alcohol misuse among nursing students, guided by the research question: "What is the current state of alcohol misuse among U.S. nursing students?" Evidence was drawn from several scholarly sources. Articles were included if they addressed U.S. nursing students; alcohol misuse; substance abuse or chemical impairment; prevalence rates; and/or characteristics including nursing student behaviors, attitudes, and beliefs. Using thematic analysis, common themes were extracted, followed by hand coding those themes and using NVivo qualitative software. Six studies met inclusion criteria. Three themes, eight subthemes, and several gaps in knowledge were identified. The themes include "high prevalence exists," "necessity of supportive environments," and "hopelessness without policies." Subthemes include "root cause," "vulnerable population," "scholarship and substance use," "education," "identification of risk factors," "prevention and deterrents," "safety," "ethical and legal issues," and "consequences." On the basis of this analysis, several research questions were developed to explore alcohol misuse in this population. Alcohol was the most often used substance. Nursing students were unaware of a safe level of consumption and the potential negative health-related and professional effects associated with alcohol misuse.

    Alcoholism is a debilitating disorder that can take a significant toll on health and professional and personal relationships. Excessive alcohol consumption can have a serious impact on both drinkers and developing fetuses, leading to long-term learning impairments. Decades of research in laboratory animals and humans have demonstrated the value of eyeblink classical conditioning (EBC) as a well-characterized model system to study the neural mechanisms underlying associative learning. Behavioral EBC studies in adults with alcohol use disorders and in children with fetal alcohol spectrum disorders report a clear learning deficit in these two patient populations, suggesting alcohol-related damage to the cerebellum and associated structures. Insight into the neural mechanisms underlying these learning impairments has largely stemmed from laboratory animal studies. In this mini-review, we present and discuss exemplary animal findings and data from patient and neuroimaging studies. An improved understanding of the neural mechanisms underlying learning deficits in EBC related to alcoholism and prenatal alcohol exposure has the potential to advance the diagnoses, treatment, and prevention of these and other pediatric and adult disorders.

    2014-01-01

    Full Text Available Alcohol dependence is a serious psychiatric disorder with harmful physical, mental and social consequences, and a high probability of a chronic relapsing course. The field of pharmacologic treatment of alcohol dependence and craving is expanding rapidly; the drugs that have been found to reduce relapse rates or drinking in alcohol-dependent patients and are approved for treatment of alcohol dependence are naltrexone, acamprosate and disulfiram, whereas also topiramate appears as a promising therapy. For many patients, however, these treatments are not effective. Evidence from a number of different studies suggests that genetic variation is a significant contributor to interindividual variation of clinical presentation of alcohol problems and response to a given treatment. The aim of the present review is to summarize and discuss the findings on the association between gene polymorphisms and the response to alcohol dependence treatment medications. It is anticipated that future implementation of pharmacogenomics in clinical practice will help personalize alcohol dependence drug treatment, and development personalized hospital pharmacology.

    Full Text Available The objective of this study was to investigate residential exposure to alcohol outlets in relation to alcohol consumption and mental health morbidity (anxiety, stress, and depression. This was a cross-sectional study of 6,837 adults obtained from a population representative sample for the period 2006-2009 in Perth, Western Australia. The number of alcohol outlets was ascertained for a 1600 m service area surrounding the residential address. Zero-inflated negative binomial and logistic regression were used to assess associations with total alcohol consumption, harmful alcohol consumption (7-10 drinks containing 10 g of alcohol for men, 5-6 drinks for women and medically diagnosed and hospital contacts (for anxiety, stress, and depression, respectively. The rate ratio for the number of days of harmful consumption of alcohol per month and the number of standard drinks of alcohol consumed per drinking day was 1.06 (95% CI: 1.02, 1.11 and 1.01 (95% CI: 1.00, 1.03 for each additional liquor store within a 1600 m service area, respectively. The odds ratio of hospital contact for anxiety, stress, or depression was 1.56 (95% CI: 0.98, 2.49 for those with a liquor store within the service area compared to those without. We observed strong evidence for a small association between residential exposure to liquor stores and harmful consumption of alcohol, and some support for a moderate-sized effect on hospital contacts for anxiety, stress, and depression.

    This study simultaneously evaluated multiple circulating neurohormones, osmolality, thirst, and fluid balance in eight actively drinking, alcoholic males and seven controls before and 12 hr after an ethanol challenge. Basal levels of serum osmolality and thirst were significantly higher in alcoholics compared with controls, yet actively drinking alcoholics at the start of the study had normal vasopressin (AVP) levels, plasma angiotensin II (Ang II), plasma renin activity, plasma aldosterone (Aldo), and plasma catecholamines. In response to ethanol, serum osmolalities rose significantly higher while plasma AVP levels became significantly suppressed in alcoholics. After the ethanol stimulus, plasma Ang II levels of alcoholics were significantly higher than those of controls at 11 AM (12.15 +/- 4.49 vs. 1.83 +/- 0.6 pg/ml, p less than 0.02) and 12 noon (14.93 +/- 6.81 vs. 1.37 +/- 0.17 pg/ml, p less than 0.04). Neither plasma renin activity nor Aldo changed in accordance with the elevated plasma Ang II in alcoholics. Diuresis in the alcoholics, assessed by the sum of urine output following the challenge dose, was significantly less than that of controls. Thirst scores and fluid intakes after the ethanol challenge did not differ between alcoholics and controls. The lack of an Ang II-mediated increase in plasma Aldo or thirst response suggests that ethanol may have a specific blunting effect on Ang II receptors. This study demonstrates that ethanol can be used as a provocative test in chronic alcoholics to uncover aberrant hormonal responses for two systems, namely, Ang II and AVP.(ABSTRACT TRUNCATED AT 250 WORDS)

    This article provides information on the amount of alcohol consumed by students during college sports events. It examines the relationship between alcohol consumption and the rank of the match, sex of the players (male vs. female league), and sex of the spectators. The study was carried out during an interdepartmental volleyball championship (cup system) at the University of Warmia and Mazury in Olsztyn (Poland), which included 16 matches (in both male and female leagues). The research sample consisted of 2,683 students between ages 19 and 24 years (including 1,768 men and 915 women) who came to cheer on their peers at the matches. Two objective measurements of alcohol consumption were used: (a) the number of empty alcohol packages left behind by the spectators at the sports facilities after each match and (b) breath alcohol analysis tests given to volunteering spectators after each match (in which 323 persons consented to participate). Male league games were accompanied by more alcohol consumption than were female league games, and male spectators drank more than female spectators. The most drinking occurred among men watching the male league, and the least amount of drinking occurred among women watching the female league. Alcohol intoxication increased with the rank of the match mostly among men watching the male league. The sex of players and spectators seems to be a mediating factor in the relationship between the rank of a match and the amount of alcohol consumed.

    Perceived peer alcohol use is a predictor of consumption in college males; frequent references to alcohol on Facebook may encourage alcohol consumption. Content analysis of college males' Facebook profiles identified references to alcohol. The average age of 225 identified profiles was 19.9 years. Alcohol references were present on 85.3% of the profiles; the prevalence of alcohol was similar across each undergraduate grade. The average number of alcohol references per profile was 8.5 but increased with undergraduate year (p = .003; confidence interval = 1.5, 7.5). Students who were of legal drinking age referenced alcohol 4.5 times more than underage students, and an increase in number of Facebook friends was associated with an increase in displayed alcohol references (p < .001; confidence interval = 0.009, 0.02). Facebook is widely used in the college population; widespread alcohol displays on Facebook may influence social norms and cause increases in male college students' alcohol use.

    This paper presents findings of a qualitative study of older people's use of alcohol during retirement and identifies ways that an improved understanding of older people's drinking can inform policy approaches to alcohol and active and healthy ageing. Qualitative semi-structured interviews conducted with a self-selecting sample of retired people. Participants were recruited from three geographical locations in the West of Scotland. A quota sampling design was used to ensure a broad spread of participants in terms of socio-economic position, age and gender. In total 40 participants were interviewed and the data analysed thematically using Braun and Clarke's (2006) approach. Amongst those who used alcohol, it was most often framed in terms of pleasure, relaxation, socialising and as a way to mark the passage of time. Alcohol was often associated with social occasions and interactions both in private and in public spaces. There were also many examples of the use of imposed routines to limit alcohol use and of a decreasing volume of alcohol being consumed as participants aged. This suggests that older people are often active in constructing what they regard as 'healthier' routines around alcohol use. However, processes and circumstances associated with ageing can lead to risk of social isolation and/or increased alcohol consumption. Such processes include retirement from paid work and other 'biographical disruptions' such as caring for a partner, bereavement and/or loss of social networks. These findings highlight processes that can result in changes in drinking habits and routines. Whilst these processes can be associated with a reduction or cessation of alcohol use as people age, they can also be associated with increased risk of harmful alcohol consumption. Fractured or disrupted routines, particularly those associated with bereavement or the burden of caring responsibilities, through increasing the risk of loneliness and isolation, can construct increased risk of

    Alcohol dependence is a major public health problem that is characterised by recidivism and a host of medical and psychosocial complications. Besides psychosocial interventions, different pharmacological interventions have been or currently are under investigation through Cochrane systematic reviews. The primary aim of the review is to assess the benefits/risks of anticonvulsants for the treatment of alcohol dependence. We searched the Cochrane Drugs and Alcohol Group Trials Register (October 2013), PubMed (1966 to October 2013), EMBASE (1974 to October 2013) and CINAHL (1982 to October 2013). Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing anticonvulsants alone or in association with other drugs and/or psychosocial interventions versus placebo, no treatment and other pharmacological or psychosocial interventions. We used standard methodological procedures as expected by The Cochrane Collaboration. A total of 25 studies were included in the review (2641 participants). Most participants were male, with an average age of 44 years. Anticonvulsants were compared with placebo (17 studies), other medications (seven studies) and no medication (two studies). The mean duration of the trials was 17 weeks (range four to 52 weeks). The studies took place in the USA, Europe, South America, India and Thailand. Variation was reported in the characteristics of the studies, including their design and the rating instruments used. For many key outcomes, the risk of bias associated with unclear or unconcealed allocation and lack of blinding affected the quality of the evidence.Anticonvulsants versus placebo: For dropouts (16 studies, 1675 participants, risk ratio (RR) 0.94, 95% confidence interval (Cl) 0.74 to 1.19, moderate-quality evidence) and continuous abstinence (eight studies, 634 participants, RR 1.21, 95% Cl 95% 0.97 to 1.52, moderate-quality evidence), results showed no evidence of differences. Moderate-quality evidence suggested that

    Full Text Available Suicide is an escalating public health problem, and alcohol use has consistently been implicated in the precipitation of suicidal behavior. Alcohol abuse may lead to suicidality through disinhibition, impulsiveness and impaired judgment, but it may also be used as a means to ease the distress associated with committing an act of suicide. We reviewed evidence of the relationship between alcohol use and suicide through a search of MedLine and PsychInfo electronic databases. Multiple genetically-related intermediate phenotypes might influence the relationship between alcohol and suicide. Psychiatric disorders, including psychosis, mood disorders and anxiety disorders, as well as susceptibility to stress, might increase the risk of suicidal behavior, but may also have reciprocal influences with alcohol drinking patterns. Increased suicide risk may be heralded by social withdrawal, breakdown of social bonds, and social marginalization, which are common outcomes of untreated alcohol abuse and dependence. People with alcohol dependence or depression should be screened for other psychiatric symptoms and for suicidality. Programs for suicide prevention must take into account drinking habits and should reinforce healthy behavioral patterns.

    In 2009, the Food and Drug Administration (FDA) banned characterising flavours in cigarettes (except for menthol) due to their appeal to teen starter smokers. In August 2016, the agency deemed all tobacco products to be under its authority and a more comprehensive flavour ban is under consideration. To determine the scope and scale of alcohol-flavoured tobacco products among cigars & cigarillos, hookahs and electronic cigarettes (e-cigarettes). Alcohol-flavoured tobacco products were identified by online search of tobacco purveyors' product lines and via Google search cross-referencing the various tobacco product types versus a list of alcoholic beverage flavours (eg, wine, beer, appletini, margarita). 48 types of alcohol-flavoured tobacco products marketed by 409 tobacco brands were identified. Alcohol flavours included mixed drinks (n=25), spirits (11), liqueurs (7) and wine/beer (5). Sweet and fruity tropical mixed drink flavours were marketed by the most brands: piña colada (96), mojito (66) and margarita (50). Wine flavours were common with 104 brands. Among the tobacco product categories, brands offering alcohol-flavoured e-cigarettes (280) were most numerous, but alcohol-flavoured products were also marketed by cigars & cigarillos (88) and hookah brands (41). Brands by major tobacco companies (eg, Philip Morris, Imperial Tobacco) were well represented among alcohol-flavoured cigars & cigarillos with five companies offering a total of 17 brands. The widespread availability of alcohol-flavoured tobacco products illustrates the need to regulate characterising flavours on all tobacco products. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  16. Alcoholism between Fiction and Reality.

    Science.gov (United States)

    Carota, Antonio; Calabrese, Pasquale

    2013-01-01

    Alcoholism has always been emphasized in literature, narratives, and theater as its prevalence and related disability are very high, is found throughout the world, and affects women and men of all ages and social classes. There is a tragic or romantic fascination in the deep sense of personal failure that drinking is able to relieve and in the uncontrollable inability to stop drinking. These aspects have been portrayed well by fictional alcoholics in movies and novels. It has become evident that biological traits together with a complex series of psychosocial factors (e.g. negative life events, depression, anxiety, and other psychiatric or personality disorders), which are also well represented in novels and movies, can lead to alcohol addiction. Behavioral (euphoria, disinhibiting behaviors, aggressiveness) and neurological changes (confusion, bradypsychism, slurred speech, ataxia, blackouts) related to alcohol intoxication are also well portrayed by fictional characters. Delirium tremens, epilepsy, alcohol dementia, and Wernicke-Korsakoff disease, however, find less representation in literature and on the stage and screen. The treatment of alcoholic dependence is very difficult (as often reported by fictional and real stories), but should never be considered hopeless. It should be initiated at any stage of the disease. The support offered by Alcoholics Anonymous has always had great appeal for the public. Fictional works can portray alcohol addiction superbly and show some dark sides of human nature (negative emotions and autodestructive thoughts and behaviors), and, at the same time, the severity and pervasiveness of mental illnesses. The psychiatric and psychosocial aspects of alcohol addiction in movies and novels could be an inspiring source for new psychological studies and rehabilitation programs.

    The last issue of the Alcohol Fuels Process R/D Newsletter contained a work breakdown structure (WBS) of the SERI Alcohol Fuels Program that stressed the subcontracted portion of the program and discussed the SERI biotechnology in-house program. This issue shows the WBS for the in-house programs and contains highlights for the remaining in-house tasks, that is, methanol production research, alcohol utilization research, and membrane research. The methanol production research activity consists of two elements: development of a pressurized oxygen gasifier and synthesis of catalytic materials to more efficiently convert synthesis gas to methanol and higher alcohols. A report is included (Finegold et al. 1981) that details the experimental apparatus and recent results obtained from the gasifier. The catalysis research is principally directed toward producing novel organometallic compounds for use as a homogeneous catalyst. The utilization research is directed toward the development of novel engine systems that use pure alcohol for fuel. Reforming methanol and ethanol catalytically to produce H/sub 2/ and CO gas for use as a fuel offers performance and efficiency advantages over burning alcohol directly as fuel in an engine. An application of this approach is also detailed at the end of this section. Another area of utilization is the use of fuel cells in transportation. In-house researchers investigating alternate electrolyte systems are exploring the direct and indirect use of alcohols in fuel cells. A workshop is being organized to explore potential applications of fuel cells in the transportation sector. The membrane research group is equipping to evaluate alcohol/water separation membranes and is also establishing cost estimation and energy utilization figures for use in alcohol plant design.

    A patient with chronic alcoholism presented with myelopathy and low serum folate and cobalamin levels. A 42-year-old alcoholic man had gait disturbance for 4 months. A neurological examination revealed marked spasticity with increased deep tendon reflexes and extensor plantar responses of the lower limbs. His cobalamin level was decreased and his serum folate level was particularly low. His plasma ammonia level was not increased. Abstinence and folic acid and cobalamin supplementation stopped the progression of his neurological deficits. This case indicates that nutritional deficiency should be monitored closely in patients with chronic alcoholism who present with myelopathy. PMID:28049986

    Alcoholism and other forms of substance abuse affect between 10% and 15% of dentists, and the damage caused is well documented and understood. In the face of this, recovery rates remain below 20%. The key is in understanding the mind of the alcoholic. There are clear patterns of denial and ineffective coping that accompany the approximately ten to fifteen years over which addiction is established. Successful recovery invariably begins with a crisis that forces a change in mindset. Recovery involves mental vision of a continuous and lifelong growth process that does not involve alcohol.

    Full Text Available Organophosphates, which can cause occupational poisoning due to inappropriate personal protective measures, are widely used insecticides in agricultural regions of southern Turkey. Therefore, the classical clinical findings of this cholinergic poisoning are myosis, excessive secretions, bradicardia and fasciculations are easy to be recognized by local medical stuff. Diseases and conditions related to alcoholism such as mental and social impairments, coma, toxicity, withdrawal, and delirium are frequent causes of emergency visits of chronic alcoholic patients. Here we present a case diagnosed and treated as organophosphate poisoning although it was an alcohol withdrawal in the beginning and became delirium tremens, due to similar symptoms.

    The sulfated minerals present in mining areas may cause serious environmental problems, because of the chemolithotrophic bacteria action of the gender Thiobacillus, mainly the T. ferroxidans and T. thio-oxidans. These microorganisms are able to oxidize mineral sulfates, elementary sulfur and the ferrous ion (T. ferroxidans), being capable of mobilizing radionuclides as the uranium for the environment. In this context, this study had the aim of investigating the occurrence and the fluctuations in the T. ferroxidans and T. thio-oxidans populations, in mine, effluent, tailing dam and waste rock of the Mine and Mill Industrial Complex of Pocos de Caldas-MG (ICPC). The relative seasonal behavior of some variables, when evaluated simultaneously indicated that the high values of oxidation-reduction potential, the low values of pH, the detection of the largest percentages of incidence and highest values of T. ferroxidans and T. thio-oxidans counting, observed in the sites 075, BIA, CM, BF4, BF8 and BE, indicated that these are the principal places of mine acid drainage occurrence and bio-leaching bacteria action in the ICPC and be considered critical sites, faced to a possible decommission measure.

    Alcoholism is a disease that greatly ruins body mental health, family's health, and a social property. Moreover, it is a disease that a few drinking are connected with the danger of the relapse because there is a control trouble of the drinking desire. The purpose of this survey is to clarify the relation between television commercial of alcoholic beverage (CM) and alcoholism. Questionnaire survey on CM and the drinking desire of alcoholism was carried out. Participants were 104 abstinent patients (AP) and 221 healthy control subjects (HCS). HCS were ruled out alcohol dependence syndrome range by Alcohol Use Disorders Identification Test. Statistical analysis was performed using Chi-square and Fisher's exact tests as well as adjusted residuals to compare AP and HCS. In addition, AP was analyzed the relationship between period of abstinence and CM. The average period of abstenence from drinking was 3.38 +/- 1.55 years. AP had the experience of receiving stimulation to the drinking desire by CM. AP had the unpleasantness to the CM. Also, they hoped to discontinue CM, they felt the unpleasantness when they watched CM. Generally, three years are considered to be a stability period after abstains from drinking. Thirty-seven% of AP with 3 years and 27% of AP with 5 years answered "It is very which question about "I want to drink alcohol when I watched CM of alcohol beverage". It was suspected the CM stimulation was a risk element of an external trigger of the drinking desire, and AP had significantly felt "unpleasant" and hoped that "Discontinuance of CM". It was suggested that it is necessary to reconsider the CM stimulation from the viewpoint of relapse prevention of AP.

    Alcoholic hepatitis is a pro-inflammatory chronic liver disease that is associated with high short-term morbidity and mortality (25%-35% in one month) in the setting of chronic alcohol use. Histopathology is notable for micro- and macrovesicular steatosis, acute inflammation with neutrophil infiltration, hepatocellular necrosis, perivenular and perisinusoidal fibrosis, and Mallory hyaline bodies found in ballooned hepatocytes. Other findings include the characteristic eosinophilic fibrillar material (Mallory's hyaline bodies) found in ballooned hepatocytes. The presence of focal intense lobular infiltration of neutrophils is what typically distinguishes alcoholic hepatitis from other forms of hepatitis, in which the inflammatory infiltrate is primarily composed of mononuclear cells. Management consists of a multidisciplinary approach including alcohol cessation, fluid and electrolyte correction, treatment of alcohol withdrawal, and pharmacological therapy based on the severity of the disease. Pharmacological treatment for severe alcoholic hepatitis, as defined by Maddrey's discriminant factor ≥ 32, consists of either prednisolone or pentoxifylline for a period of four weeks. The body of evidence for corticosteroids has been greater than pentoxifylline, although there are higher risks of complications. Recently head-to-head trials between corticosteroids and pentoxifylline have been performed, which again suggests that corticosteroids should strongly be considered over pentoxifylline.

    2012-01-01

    As a consequence of Sweden joining the European Union, privately imported alcohol is increasingly sold within illegal contexts (i.e., smuggled alcohol). One implication of the smuggled alcohol is that alcohol becomes more available to underage drinkers. In the Swedish debate, smuggled alcohol has been formulated as a youth problem. The aim of this…

  7. Risks of alcoholic energy drinks for youth.

    Science.gov (United States)

    Weldy, David L

    2010-01-01

    Ingesting alcohol and energy drinks together is associated with a decreased awareness of the physical and mental impairment caused by the alcohol without reducing the actual impairment. This is of particular concern for youth who have a baseline of less mature judgment. Adding energy drinks to alcohol tends to increase the rate of absorption through its carbonation and dilution of the alcohol, and keep a person awake longer allowing ingestion of a greater volume of alcohol. At low blood alcohol levels, caffeine appears to decrease some of the impairment from the alcohol, but at higher blood alcohol levels, caffeine does not appear to have a modifying effect on either the physical or mental impairment induced by the alcohol. Obtaining this combination is made easier and more affordable for under aged persons by manufacturers of premixed alcoholic energy drink combination beverages. Awareness by medical and educational personnel and parents of this activity and its potential for harm is unknown.

    1984-01-01

    Erectile impotence is a common complaint in alcoholics, but its mechanism is unknown. We have studied nocturnal penile erection in 13 alcoholics who complained of impotence. Seven had normal erections and their impotence was therefore psychogenic. Six were found to have diminished or absent nocturnal erections. Plasma concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were elevated in this latter group, with the exception of one patient who had only raised FSH. They also had more evidence of neurological damage than the other seven alcoholics, and two had evidence of damage to the parasympathetic nervous system. Investigation of erection during sleep in alcoholic patients with impotence may be useful in differentiating clinically between patients with psychogenic causes and patients with organic causes of impotence.

    Full Text Available Chronic liver damage caused by viral infection, alcohol, or obesity can result in increased risk for hepatocellular carcinoma (HCC. Ample epidemiological evidence suggests that there is a strong synergism between hepatitis C virus (HCV and alcoholic liver diseases (ALD. The Toll-like receptor (TLR signaling pathway is upregulated in chronic liver diseases. Alcoholism is associated with endotoxemia that stimulates expression of proinflammatory cytokine expression and inflammation in the liver and fat tissues. Recent studies of HCC have centered on cancer-initiating stem cell (CSC, including detection of CSC in cancer, identification of CSC markers, and isolation of CSC from human HCC cell lines. Synergism between alcohol and HCV may lead to liver tumorigenesis through TLR signaling.

    Full Text Available Alcoholism is a serious social problem due to its impact on individual and collective health. In order to provide an update on the latest findings that explain the development and symptoms of alcohol addiction, the short and long term changes that this disorder causes in the central nervous system are shown in this paper. A total of 52 information sources were consulted, including 43 journal articles, 4 books and statistical reports. The main network managers were used. The interaction of ethanol with various structures of the neuronal membrane affects the cytoarchitecture and brain function associated with the reward system, motor processing, learning and memory, resulting in the development of alcohol dependence. In addition, ethanol-induced changes in excitation/inhibition explain the phenomena of alcohol tolerance and withdrawal.

    Worker absenteeism due to substance abuse costs the Alberta economy approximately $720 million a year. It is estimated that 20 per cent of all drivers in fatal crashes were using alcohol, and the use of cannabis and cocaine in Alberta has more than doubled over the last 15 years. In addition, 1 in 10 Alberta workers have reported using alcohol while at work and 4 per cent have reported using alcohol 4 hours prior to coming to work during the previous 12 months. In an effort to ensure appropriate health and safety for workers in the Canadian petroleum industry, 6 trade associations in the sector have joined together as the Enform Alcohol and Drug Initiative and are now working to develop a common approach to drug and alcohol guidelines and workplace rules. The task group will determine if existing policies and guidelines are sufficient to ensure a safe workplace and will consider standardizing the testing, application and rehabilitation of workers with respect to the use of drugs and alcohol. In the past, disciplinary actions have often been reversed because employers have not been consistent or did not follow established alcohol and drug policies or test to specific standards. Various work rules for inappropriate alcohol and drug use were reviewed, as well as education and communication strategies regarding policy content. Standards for testing criteria were discussed, as well as issues concerning duty-to-accommodate circumstances. An excerpt of concentration standards was presented. It was concluded that a matrix for companies to assess and determine safety sensitive positions is needed. refs., tabs., figs.

    While psychological conflict about dependency needs of alcoholic and obese persons has been widely observed, few studies have examined differences in dependency characteristics between these clinical groups. The Interpersonal Dependency Inventory was administered to 22 alcoholic and 8 morbidly obese men in intensive treatment for alcohol and obesity. The original hypothesis that alcoholic and obese men would show similar dependency needs was supported. Dependency correlates of personality may serve as useful predictor variables in the clinical treatment of alcoholic and obese persons.

Direct markers (mainly blood or serum and urine ethanol, ethylglucuronide, ethyl sulfate, and phosphatidylethanol directly track the intake of alcohol and vary in their sensitivity and kinetics of appearance and clearance. Indirect markers (mean corpuscular volume,γ-glutamyl transferase, alanine aminotransferase and aspartate aminotransferase, and carbohydrate-deficient transferrin are biological parameters that are influenced by a steady and significant alcohol intake. We discuss the values of these tests and the relevance of their prescriptions for the clinical evaluation of heavy drinking. We indicate, when known, the pathophysiological mechanism of their elevations. We also discuss the amount and time of alcohol consumption required to give a positive result and the duration of abstinence required for the return to normal values. The forensic use of these biomarkers will not be considered in this review.Keywords: alcoholism, biomarker, CDT, relapse, alcohol-induced liver disease

  2. Grain alcohol study: summary

    Energy Technology Data Exchange (ETDEWEB)

    The study has concentrated upon a detailed examination of all considerations involved in the production, use, and marketing of ethyl alcohol (Ethanol) as produced from the fermentation of agricultural grains. Each parameter was examined in the light of current energy markets and trends; new sources and technological, and processes for fermentation, the capability of the agricultural industry to support fermentaton demand; the optimization of value of agricultureal crops; and the efficiencies of combining related industries. Anhydrous (200 proof) ethanol makes an excellent blending component for all present automotive fuels and an excellent octane additive for unleaded fuels in proportions up to 35% without requiring modifications to current engines. There is no difference between ethanol produced by fermentation and ethanol produced synthetically from petroleum. The decision to produce ethanol one way or the other is purely economic. The agricultural industry can support a major expansion in the fermentation industry. The residue (distillers grains) from the fermentation of corn for ethanol is an excellent and economical feed for livestock and poultry. A reliable supply of distillers grains can assist in making the large beef feedlot operations more economically viable. The source materials, fuels, products and by-products of an ethanol plant, beef feedlot, gas biodigester plant, municipal waste recovery plant and a steam generated electrical plant are interrelated and mutually beneficial for energy efficiencies and economic gains when co-located. The study concludes that the establishment of such agricultural-environment industrial energy complexes, would provide a broad range of significant benefits to Indiana.

    2016-05-01

    To assess the immediate effect of alcohol promoting and alcohol warning advertisements on implicit and explicit attitudes towards alcohol and on alcohol seeking behaviour. 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. 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). 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. © The Author 2015.

  5. Psychoanalytic treatment of psychological addiction to alcohol (alcohol abuse).

    Science.gov (United States)

    Johnson, Brian

    2011-01-01

    The DSM-V Committee plans to abolish the distinction between Alcohol Abuse and Alcohol Dependence (dsm5.org). The author presents a case report as a proof of concept that this distinction should be retained. The author has asserted that Alcohol Abuse is a purely psychological addiction, while Alcohol Dependence involves capture of the ventral tegmental dopaminergic SEEKING system (Johnson, 2003). In psychological addiction the brain can be assumed to function normally, and ordinary psychoanalytic technique can be followed. For the patient described, transference interpretation was the fundamental key to recovery. Alcoholic drinking functioned to prevent this man from remembering overwhelming childhood events; events that were also lived out in his current relationships. Murders that occurred when he was a child were hidden in a screen memory. The patient had an obsessional style of relating where almost all feeling was left out of his associations. After he stopped drinking compulsively, he continued to work compulsively. The maternal transference had to be enacted and then interpreted in order for overwhelming memories to be allowed into conscious thought. After psychoanalysis, the patient resumed drinking and worked a normal schedule that allowed more fulfilling relationships. He had no further symptoms of distress from drinking over a 9-year followup. This case illustrates that Alcohol Abuse is a purely psychological illness, that it does not have the brain changes typical of Alcohol Dependence. Combining epidemiological, neurobiological, longitudinal, and psychoanalytic observations would allow multiple sources of information to be used in creating diagnostic categories. Losing details of human behavior by relying only on epidemiological studies is likely to cause errors in categorization of disorders. In turn, having faulty categories as the basis of further research is likely to impair identification of specific effective treatments.

  6. Alcohol-induced Cushing syndrome. Hypercortisolism caused by alcohol abuse.

    2011-01-01

    Cushing's syndrome (CS), a rare syndrome caused by overexposure to glucocorticoids, is difficult to diagnose. The underlying causes of CS include pituitary and ectopic adrenocorticotropic hormone (ACTH) producing tumours and adrenal adenomas or hyperplasia. Alcoholism, however, can cause similar symptoms, giving rise to a so-called pseudo-Cushing state, which aggravates the differential diagnostic dilemmas of CS. To document any specific clinical or biochemical features of alcohol-induced CS. A Medline computer-aided search was performed to identify studies that have attempted to differentiate between alcohol-induced pseudo-Cushing and CS. Only original articles, not reviews, written in English were included. A total of 62 articles were included. Clinical and biochemical abnormalities mimicking increased hypothalamus-pituitary-adrenal (HPA) axis activity were found in the majority of the patients, although the severity of the changes varied widely. The most frequently occurring abnormalities were: insufficient suppression after low-dose dexamethasone or increased 24-hour urinary free cortisol (UFC). After alcohol withdrawal, cortisol decreased and dexamethasone-induced suppression of cortisol increased. No differences were noted between alcoholic and control subjects after an ACTH stimulation test, insulin tolerance test or metyrapone test. Differences were found after a naloxone test and hexarelin test. Studies using corticotropin-releasing hormone stimulation and tests after ethanol ingestion revealed inconclusive results. There is no clear definition for the alcohol-induced pseudo-Cushing state, and hitherto studies fail to provide clues to differentiate between pseudo-Cushing and Cushing's syndrome. Only cessation of alcohol can normalise biochemical abnormalities and regress hypercortisolic symptoms.

    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

    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.

    Alcohol is a common target of counterfeiting in Russia. Counterfeit alcohol is defined here as the manufacture, distribution, unauthorized placement (forgery) of protected commodity trademarks, and infringement of the exclusive rights of the registered trademark holders of alcoholic beverages. It is often argued that the expansion of the counterfeit product market is due to the steady demand of economically disadvantaged people for low-priced goods. The situation becomes more complicated once deceptive and nondeceptive forms of counterfeiting are taken into account. This study aimed to identify markers of risky behavior associated with the purchase of counterfeit alcohol in Russia. The analysis relied on consumer self-reports of alcohol use and purchase collected nationwide by the Russia Longitudinal Monitoring Survey (RLMS-HSE) in 2012 to 2014. I used a generalized linear mixed-model logistic regression to identify predictors of risky behavior by consumers who purchased counterfeit alcohol, either knowingly or unknowingly, during the 30 days preceding the survey. Purchases of counterfeit alcohol declined slightly from 2012 to 2014, mainly due to a decrease in consumers mistakenly purchasing counterfeit products. Predictors of counterfeit alcohol purchases differed between consumers who knowingly and unknowingly purchased counterfeit products. Nondeceptive purchase of counterfeit alcohol was related primarily to an indifference to alcohol brands. Consumers with social networks that include drinkers of nonbeverage alcohol and producers of homemade alcohol were highly likely to consume counterfeit alcohol deliberately. Problem drinking was significantly associated with a higher risk of both deceptive and nondeceptive purchases of counterfeit alcohol. Poverty largely contributed to nondeceptive counterfeiting. The literature has overestimated the impact of low prices on counterfeit alcohol consumption. Problem drinking and membership in social networks of consumers

    Over the past 30 years the role of alcohol (ethanol) in the development of acute and chronic pancreatitis has been intensively investigated. However, ethanol is generally consumed in form of alcoholic beverages which contain numerous non-alcoholic compounds. At least on gastric acid secretion it has been convincingly demonstrated that alcohol and alcoholic beverages have markedly different effects. In the present article, we provide an overview about the effect of different non-alcoholic cons...

  15. Alcohol's Effects on Lipid Bilayer Properties

    2011-01-01

    Alcohols are known modulators of lipid bilayer properties. Their biological effects have long been attributed to their bilayer-modifying effects, but alcohols can also alter protein function through direct protein interactions. This raises the question: Do alcohol's biological actions result predominantly from direct protein-alcohol interactions or from general changes in the membrane properties? The efficacy of alcohols of various chain lengths tends to exhibit a so-called cutoff effect (i.e., increasing potency with increased chain length, which that eventually levels off). The cutoff varies depending on the assay, and numerous mechanisms have been proposed such as: limited size of the alcohol-protein interaction site, limited alcohol solubility, and a chain-length-dependent lipid bilayer-alcohol interaction. To address these issues, we determined the bilayer-modifying potency of 27 aliphatic alcohols using a gramicidin-based fluorescence assay. All of the alcohols tested (with chain lengths of 1–16 carbons) alter the bilayer properties, as sensed by a bilayer-spanning channel. The bilayer-modifying potency of the short-chain alcohols scales linearly with their bilayer partitioning; the potency tapers off at higher chain lengths, and eventually changes sign for the longest-chain alcohols, demonstrating an alcohol cutoff effect in a system that has no alcohol-binding pocket.

    The aim of this study was to examine differences in alcohol consumption and its consequences when consumed alone and when mixed with energy drinks. A survey was conducted among Dutch students at Utrecht University and the College of Utrecht. We collected data on alcohol consumption and alcohol-related consequences of alcohol consumed alone and/or alcohol mixed with energy drinks (AMED). The data were analyzed using a retrospective within-subject design, comparing occasions when subjects consumed AMED with those when they consumed alcohol only in the past 30 days. A representative sample of 6002 students completed the survey, including 1239 who consumed AMED. Compared with consuming alcohol only, when consuming AMED, students consumed significantly fewer alcoholic drinks on an average drinking day (6.0 versus 5.4, respectively), and reported significantly fewer drinking days in the previous month (9.2 versus 1.4), significantly fewer days being drunk (1.9 versus 0.5), and significantly fewer occasions of consuming more than four (female)/five (male) alcoholic drinks (4.7 versus 0.9). The maximum number of mixed alcoholic drinks (4.5) in the previous month was significantly lower when compared with occasions when they consumed alcohol only (10.7). Accordingly, the mean duration of a drinking session was significantly shorter when mixing alcoholic drinks (4.0 versus 6.0 hours). Finally, when consuming AMED, significantly fewer alcohol-related consequences were reported (2.6) for the previous year, including driving a car while intoxicated, taking foolish risks, or being injured or hurt, as compared with alcohol-related consequences when consuming alcohol only (4.9). Mixing alcohol with energy drinks decreases overall alcohol consumption, and decreases the likelihood of experiencing negative alcohol-related consequences.

    Heavy alcohol drinking is a risk factor for colorectal cancer (CRC); previous studies have shown a linear dose-dependent association between alcohol intake and CRC. However, some studies suggest that moderate alcohol consumption may have a protective effect, similar to that seen in cardiovascular disease. Other factors may interact with alcohol and contribute additional risk for CRC. We aimed to determine the association between moderate alcohol consumption, limited to 30 g of alcohol per day, by beverage type on CRC risk and to assess the effects of other factors that interact with alcohol to influence CRC risk. The PubMed database was used to find articles published between 2008 and 2014 related to alcohol and CRC. Twenty-one relevant articles were evaluated and summarized, including 11 articles reporting on CRC risk associated with moderate intake and 10 articles focusing on genetic interactions associated with alcohol and CRC risk. The association between alcohol and increased risk for CRC was found when intakes exceeded 30 g/d alcohol. Nonsignificant results were consistently reported for intakes alcohol consumers. Some significant results suggest that the development of CRC is dependent on the interaction of gene and environment. The association between the amount of alcohol consumed and the incidence of CRC was not significant at moderate intake levels. Moderate alcohol consumption was associated with a reduced CRC risk in study populations with greater adherence to a Mediterranean diet, where wine contributed substantially to the alcoholic beverage consumed. Other factors such as obesity, folate deficiency, and genetic susceptibility may contribute additional CRC risk for those consuming alcohol. To minimize CRC risk, appropriate recommendations should encourage intakes below 30 g of alcohol each day. Copyright © 2015 by the Research Society on Alcoholism.

    Alcohol dehydrogenase (ADH) was applied to produce alcohol biosensor. The enzyme was collected from cultured Bacillus sp. in solid media. From 6 tested isolates, bacteria from fermented rice grain (TST.A) showed the highest oxidation current which was further applied as the bioreceptor. Various ethanol concentrations was measured based on the increase of maximum oxidation current value. However, a reduction value was happened when the ethanol concentration was higher than 5%. Comparing the result of spectrophotometry measurement, R2 value obtained from the biosensor measurement method was higher. The new proposed method resulted a wider detection range, from 0.1-5% of ethanol concentration. The result showed that biosensor method has big potency to be used as alcohol detector in foods or bevearages.

    Objective To study the relationship between drinking environment, attitudes and situation and alcohol-related health problems. Methods A sample of 2327 respondents was randomly collected from Wuhan, Hubei Province in China by a face-to-face interview. The structural equation modeling analysis was performed for the data collected. Results Both parents' drinking behaviors and respondents' drinking situation strongly impacted the alcohol-related problems and diseases. Friends' or peers' drinking behaviors influenced the respondents' drinking attitudes and behaviors. Males experienced more alcohol-related problems and diseases than females. Conclusions Comparatively, parents' drinking behaviors exert the most significant influence on drinkers. Therefore, it is beneficial to restrict parents' drinking behaviors for the offsprings and the whole society, and an intensive professional education in early motherhood is also necessary for Chinese women.

    gamma-Hydroxybutyric acid (GHB) reduces alcohol drinking, promotes abstinence from alcohol, suppresses craving for alcohol, and ameliorates alcohol withdrawal syndrome in alcoholics. At preclinical level, GHB suppresses alcohol withdrawal signs and alcohol intake in rats. The present study was designed to investigate whether GHB administration was capable of affecting alcohol's motivational properties (the possible animal correlate of human craving for alcohol) in selectively bred Sardinian alcohol-preferring rats. To this aim, rats were initially trained to lever press for alcohol (15%, vol/vol) under a procedure of operant, oral alcohol self-administration (fixed ratio 4 in 30-min daily sessions). Once responding for alcohol had stabilized, rats were divided into two groups and allocated to two independent experiments. Experiment 1 assessed the effect of GHB (0, 25, 50, and 100mg/kg, i.p.) on breakpoint for alcohol, defined as the lowest response requirement not achieved by each rat when exposed to a single-session progressive ratio schedule of reinforcement. Experiment 2 assessed the effect of GHB (0, 25, 50, and 100mg/kg, i.p.) on single-session extinction responding for alcohol (alcohol was absent and unreinforced responding was recorded). Breakpoint and extinction responding for alcohol are reliable indexes of alcohol's motivational strength. In Experiment 1, all doses of GHB reduced--by approximately 20% in comparison to saline-treated rats--breakpoint for alcohol. In Experiment 2, administration of 25, 50, and 100mg/kg GHB reduced--by approximately 25%, 40%, and 50%, respectively, in comparison to saline-treated rats--extinction responding for alcohol. Conversely, no dose of GHB altered breakpoint and extinction responding for sucrose (3%, wt/vol) in two independent subsets of Sardinian alcohol-preferring rats. Together, these data suggest that GHB administration specifically suppressed alcohol's motivational properties in Sardinian alcohol-preferring rats

    Alcohol exposure alters oral mucosa. Patient compliance with mouthwash use may be reduced by oral pain resulting from rinsing with alcohol-containing mouthwash. However, information regarding the effects of alcohol consumption and mouthwash alcohol concentration on oral pain is limited. In this double-blind, randomized, controlled cross-over study, we investigated the effects of alcohol consumption status and mouthwash alcohol concentration on response to and perception of oral pain induced by alcohol-containing mouthwash. Fifty healthy men aged 33 to 56 years were enrolled and classified as drinkers and nondrinkers according to self-reported alcohol consumption. All subjects rinsed with two commercially available mouthwash products (which contained high and low concentrations of alcohol) and a negative control, in randomized order. Time of onset of oral pain, time of cessation of oral pain (after mouthwash expectoration), and pain duration were recorded, and oral pain intensity was recorded on a verbal rating scale. Drinkers had later oral pain onset and lower pain intensity. High-alcohol mouthwash was associated with earlier pain onset and greater pain intensity. In addition, oral pain cessation was later and pain duration was longer in nondrinkers rinsing with high-alcohol mouthwash. In conclusion, alcohol consumption status and mouthwash alcohol concentration were associated with onset and intensity of oral pain.

    In the crystal structure of the title complex, [Mn(NCS)2(C6H8N2)(H2O)3]·2C6H8N2, the Mn(II) cation is coordinated by two terminally N-bonded thio-cyanate anions, three water mol-ecules and one 2,6-di-methyl-pyrazine ligand within a slightly distorted N3O3 octa-hedral geometry; the entire complex mol-ecule is generated by the application of a twofold rotation axis. The asymmetric unit also contains an uncoordinating 2,5-di-methyl-pyrazine ligand in a general position. Obviously, the coordination to the 2,6-di-methyl-pyrazine ligand is preferred because coordination to the 2,5-di-methyl-pyrazine is hindered due to the bulky methyl group proximate to the N atom. The discrete complexes are linked by water-O-H⋯N(2,6-di-methyl-pyzazine/2,5-di-methyl-pyza-zine) hydrogen bonding, forming a three-dimensional network. In the crystal, mol-ecules are arranged in a way that cavities are formed in which unspecified, disordered solvent molecules reside. These were modelled employing the SQUEEZE routine in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The composition of the unit cell does not take into account the presence of the unspecified solvent.

    In the title compound, [Ag6(C12H10N3OS)6]·4C3H7NO, the hexa-nuclear complex mol-ecule lies about an inversion center. The six Ag atoms form a distorted octa-hedron, with Ag⋯Ag distances in the range 2.933 (1)-3.401 (1) Å. Each Ag atom is surrounded by one N atom and two thiol-ate S atoms from two deprotonated 2-hy-droxy-1-naphthaldehyde thio-semi-carb-a-zone ligands. Each ligand coordinates three Ag atoms via a bridging thiol-ate S atom and a monodentate N atom, thus two Ag3S3 hexa-gonal rings are linked together. Two dimethyl-formamide solvent mol-ecules are located in four sets of sites with half-occupancy and form O⋯H-N hydrogen bonds to the complex mol-ecule. Intra-molecular O-H⋯N hydrogen bonds are also present. The discrete hexa-nuclear clusters are further linked through π-π inter-actions into layers parallel to (001), the shortest distance between the centroids of aromatic rings being 3.698 (2) Å.

    Full Text Available The relationship between alcohol consumption and glycoconjugate metabolism is complex and multidimensional. This review summarizes the advances in basic and clinical research on the molecular and cellular events involved in the metabolic effects of alcohol on glycoconjugates (glycoproteins, glycolipids, and proteoglycans. We summarize the action of ethanol, acetaldehyde, reactive oxygen species (ROS, nonoxidative metabolite of alcohol — fatty acid ethyl esters (FAEEs, and the ethanol-water competition mechanism, on glycoconjugate biosynthesis, modification, transport and secretion, as well as on elimination and catabolism processes. As the majority of changes in the cellular metabolism of glycoconjugates are generally ascribed to alterations in synthesis, transport, glycosylation and secretion, the degradation and elimination processes, of which the former occurs also in extracellular matrix, seem to be underappreciated. The pathomechanisms are additionally complicated by the fact that the effect of alcohol intoxication on the glycoconjugate metabolism depends not only on the duration of ethanol exposure, but also demonstrates dose- and regional-sensitivity. Further research is needed to bridge the gap in transdisciplinary research and enhance our understanding of alcohol- and glycoconjugate-related diseases.

    The aim of the study was to determine the role of alcoholic drinks as a potential source of dietary fluoride by means of measuring fluoride levels in selected alcoholic drinks available on the Polish market that are also diverse in terms of the percentage content of ethanol. The study was conducted on 48 types of drinks with low, medium, and high alcohol content available on the Polish market and offered by various manufacturers, both Polish and foreign. Fluoride concentrations in individual samples were measured by potentiometric method with a fluoride ion-selective electrode. The highest fluoride levels were determined in the lowest percentage drinks (less than 10 % v/v ethanol), with the lowest fluoride levels observed in the highest percentage drinks (above 40 % v/v ethanol). In terms of types of alcoholic drinks, the highest fluoride levels were determined in beers and wines, while the lowest levels were observed in vodkas. These data confirm the fact that alcoholic beverages need to be considered as a significant source of fluoride delivered into the body.

    Antabuse treatment has mostly been applied to alcohol dependent patients although the heavy users of alcohol are responsible for the major parts of alcohol related problems in our societies. The heavy users of alcohol should be identified both by the general practitioners and the hospital doctors...... in any field and the first intervention should be a health interview connected with a biological monitoring of alcohol damages and thereby many patients would be motivated for moderate drinking. If this is not the case, heavy users should be encouraged to a 6 or better a 12 months supervised treatment...... with Antabuse. This treatment has especially been effective in employees with work-related alcohol problems....

    Alcoholics Anonymous (AA) is an international organization of recovering alcoholics that offers emotional support through self-help groups and a model of abstinence for people recovering from alcohol dependence, using a 12-step approach. Although it is the most common, AA is not the only 12-step intervention available there are other 12-step approaches (labelled Twelve Step Facilitation (TSF)). To assess the effectiveness of AA or TSF programmes compared to other psychosocial interventions in reducing alcohol intake, achieving abstinence, maintaining abstinence, improving the quality of life of affected people and their families, and reducing alcohol associated accidents and health problems. We searched the Specialized Register of Trials of the Cochrane Group on Drugs and Alcohol, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE from 1966, EMBASE from 1980, CINAHL from 1982, PsychINFO from 1967. Searches were updated in February 2005. We also inspected lists of references for relevant studies. Studies involving adults (alcohol dependence attending on a voluntary or coerced basis AA or TSF programmes comparing no treatment, other psychological interventions, 12-step variants. One reviewer (MF) assessed studies for inclusion and extracted data using a pre-defined data extraction form. Studies were evaluated for methodological quality and discussed by all reviewers. Eight trials involving 3417 people were included. AA may help patients to accept treatment and keep patients in treatment more than alternative treatments, though the evidence for this is from one small study that combined AA with other interventions and should not be regarded as conclusive. Other studies reported similar retention rates regardless of treatment group. Three studies compared AA combined with other interventions against other treatments and found few differences in the amount of drinks and percentage of drinking days.

METHOD: Subjects were selected from a Danish birth cohort that included 223 sons of alcoholic fathers (high risk; HR) and 106 matched controls (low risk; LR). Clinical...... examinations were performed at age 40 (n = 202) by a psychiatrist using structured interviews and DSM-III-R diagnostic criteria. RESULTS: HR subjects were significantly more likely than LR subjects to develop alcohol dependence (31% vs. 16%), but not alcohol abuse (17% vs. 15%). More subjects with alcohol...... abuse were in remission at age 40 than subjects with alcohol dependence. Risk did not predict remission from either alcohol abuse or alcohol dependence. CONCLUSION: Familial influences may play a stronger role in the development of alcoholism than in the remission or recovery from alcoholism....

    This study examined the association between alcohol-use problem severity, defined by number of DSM-IV alcohol Abuse and Dependence symptoms and frequency of alcohol use, and problem behavior engagement among Mexican students. A confidential survey was administered to 1229 students in grades 7-12 at two schools in a northern border city in Mexico. Youths were categorized into five groups based on their alcohol use frequency and symptoms of DSM-IV alcohol Abuse and Dependence, specifically: no lifetime alcohol use, lifetime alcohol use but none in the past year, past year alcohol use, one or two alcohol Abuse or Dependence symptoms, and three or more alcohol Abuse or Dependence symptoms. The association between five levels of alcohol-use problem severity and three problem behaviors, lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble, was examined using chi-square or Fisher's exact tests. Several alcohol-use problem severity categories were significantly different with respect to rates of lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble. Higher alcohol-use problem severity was associated with greater endorsement of problem behaviors. Knowing about variations in adolescent alcohol use and alcohol problems may be instrumental in determining if youths are also engaging in a range of other risk behaviors. Considering varying levels of alcohol use and alcohol problems is important for effective targeted prevention and treatment interventions.

  11. The Burden of Alcohol Use

    Research shows that multiple factors influence college drinking, from an individual’s genetic susceptibility to the positive and negative effects of alcohol, alcohol use during high school, campus norms related to drinking, expectations regarding the benefits and detrimental effects of drinking, penalties for underage drinking, parental attitudes about drinking while at college, whether one is member of a Greek organization or involved in athletics, and conditions within the larger community that determine how accessible and affordable alcohol is. Consequences of college drinking include missed classes and lower grades, injuries, sexual assaults, overdoses, memory blackouts, changes in brain function, lingering cognitive deficits, and death. This article examines recent findings about the causes and consequences of excessive drinking among college students relative to their non-college peers and many of the strategies used to collect and analyze relevant data, as well as the inherent hurdles and limitations of such strategies.

    Alcohol dependence often is a familial disorder and has a genetic component. Research in causative factors of alcoholism is coordinated by a multi-center program, COGA [The Collaborative Study on the Genetics of Alcoholism, Begleiter et al., 1995]. We analyzed a subset of the COGA family sample, 84 pedigrees of Caucasian ancestry comprising 745 persons, 339 of whom are affected according to DSM-III-R and Feighner criteria. Using parametric and nonparametric methods, evidence for linkage was found on chromosome 1 (near markers D1S532, D1S1588, and D1S534), as well as on chromosome 15 (near marker D15S642). Other regions of the genome showed suggestive evidence for contributing loci. Related findings are discussed in recent publications investigating linkage in humans [Reich et al., 1998] and mice [Melo et al., 1996].

    precise identification of alcohol abuse. However, the inability of the questionnaires to detect short-term changes in intake and abuse without dependence, the inconsistent predictive values of the biological markers, and the lack of evidence of an association to postoperative morbidity reduces......Patients who drink too much have more complications after surgery. The aim of this thesis was to evaluate the evidence, possible mechanisms, and prevention of the increased postoperative morbidity in alcohol abusers, defined by a consumption of at least five drinks per day. The literature could...... be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moderate to strong evidence of increased postoperative morbidity after surgical procedures on alcohol abusers. There is weak to moderate evidence of increased postoperative mortality, hospital stay, and re...

  14. Inequality, deprivation and alcohol use.

    There are major social inequalities in health within societies. Alcohol and tobacco are major preventable causes of ill health. Using data from the United Kingdom, this paper examines the social distribution of tobacco and alcohol consumption; the role that tobacco and alcohol may play in mediating or modifying social inequalities in health; and the implications of social distribution for policies to reduce harm associated with consumption of alcohol and tobacco. In the United Kingdom, as in many other countries, there is clear inverse association between socio-economic position and consumption of cigarettes. Over the past three decades, the decline in smoking has been more rapid in men and women in higher socio-economic groups. United Kingdom suggest that among employed men and women, the prevalence of non-drinking shows an inverse association with occupational status; heavy drinking differs little; and moderate drinking is more common among those of higher socio-economic status. Smoking accounts for perhaps 25% of the social class difference in coronary heart disease (CHD) mortality, more for lung cancer, less for some other diseases. healthier patterns of drinking may contribute to the lower CHD rates of higher social classes. Although other factors are clearly important in generating social inequalities, it is important to take the social distribution of alcohol and tobacco into account when formulating policy. For cigarette consumption, there is evidence that in lower socio-economic groups demand is more sensitive to price; higher socio-economic groups are more responsive to health education. There has been less research of this nature for alcohol. Available analyses suggest that price responsiveness of heavy drinking may be greatest in young men and in those with lower incomes. A pricing strategy has important equity implications.

  15. Hand antiseptics: rubs versus scrubs, alcoholic solutions versus alcoholic gels.

    This report describes three different investigations undertaken to demonstrate the advantage of fluid alcoholic hand disinfectants. In the first study, the skin compatibility of Sterillium, a liquid alcoholic rub-in hand disinfectant was compared with that of Hibiscrub, a water-based handwashing antiseptic. Using various parameters such as image analysis of removed squames (D-squames), skin roughness or transepidermal water loss, Hibiscrub was found to be significantly inferior to Sterillium. Hibiscrub caused skin irritation in 15 volunteers who could not complete the test. In a second study, the microbicidal efficacy of Sterillium and Hibiscrub was tested in surgical hand disinfection. The microbial reduction by Sterillium was significantly greater than that of Hibiscrub, immediately after application as well as after the surgical procedure. In a third study, certain alcoholic gels were tested according to the EN 1500 'hygienic hand disinfection'. None of the gels tested passed the EN 1500 within 30s. However, Sterillium met the EN 1500 requirement within 30s. We conclude that Sterillium is superior to Hibiscrub in terms of skin tolerance and microbicidal efficacy in surgical hand disinfection. It is also superior to alcoholic gels.

    Alcohol use disorders (AUDs)-a spectrum including at-risk drinking, alcohol abuse, dependence, and addiction-is a highly prevalent problem worldwide with a substantial economic impact. The toll of alcohol on individual health and healthcare systems is devastating. Alcohol is estimated to be the fifth leading risk factor for global disability-adjusted life years. Tackling the problem of AUD requires a comprehensive strategy that includes solid action on price, availability, and marketing of alcohol. Restricting or banning alcohol advertising may reduce exposure to the risk posed by alcohol at the individual and general population level. Warning labels about the cancer risks associated with drinking have a high degree of public support and may be an inexpensive and acceptable way to educate the public. Religiosity may reduce risk behaviors and contribute to health decision making related to alcohol use.
