    Engineered microbes offer the opportunity to design and implement artificial molecular pathways for renewable production of tailored chemical commodities. Targeted biosynthesis of odd-chain fatty alcohols is very challenging in microbe, due to the specificity of fatty acids synthase for two-carbon unit elongation. Here, we developed a novel strategy to directly tailor carbon number in fatty aldehydes formation step by incorporating α-dioxygenase (αDOX) from Oryza sativa (rice) into Escherichia coli αDOX oxidizes Cn fatty acids (even-chain) to form Cn-1 fatty aldehydes (odd-chain). Through combining αDOX with fatty acyl-acyl carrier protein (-ACP) thioesterase (TE) and aldehyde reductase (AHR), the medium odd-chain fatty alcohols profile (C11, C13, C15) was firstly established in E. coli. Also, medium even-chain alkanes (C12, C14) were obtained by substitution of AHR to aldehyde decarbonylase (AD). The titer of odd-chain fatty alcohols was improved from 7.4mg/L to 101.5mg/L in tube cultivation by means of fine-tuning endogenous fatty acyl-ACP TE (TesA'), αDOX, AHRs and the genes involved in fatty acids metabolism pathway. Through high cell density fed-batch fermentation, a titer of 1.95g/L odd-chain fatty alcohols was achieved, which was the highest reported titer in E. coli. Our system has greatly expanded the current microbial fatty alcohols profile that provides a new brand solution for producing complex and desired molecules in microbes. PMID:25773521

    Different lines of alcohol dehydrogenases (ADHs) have separate superfamily origins, already recognized but now extended and re-evaluated by re-screening of the latest databank update. The short-chain form (SDR) is still the superfamily with most abundant occurrence, most multiple divergence, most prokaryotic emphasis, and most non-complicated architecture. This pattern is compatible with an early appearance at the time of the emergence of prokaryotic cellular life. The medium-chain form (MDR) is also old but second in terms of all the parameters above, and therefore compatible with a second emergence. However, this step appears seemingly earlier than previously considered, and may indicate sub-stages of early emergences at the increased resolution available from the now greater number of data entries. The Zn-MDR origin constitutes a third stage, possibly compatible with the transition to oxidative conditions on earth. Within all these three lines, repeated enzymogeneses gave the present divergence. MDR-ADH origin(s), at a fourth stage, may also be further resolved in multiple or extended modes, but the classical liver MDR-ADH of the liver type can still be traced to a gene duplication ~550 MYA (million years ago), at the early vertebrate radiation, compatible with the post-eon-shift, "Cambrian explosion". Classes and isozymes correspond to subsequent and recent duplicatory events, respectively. They illustrate a peculiar pattern with functional and emerging evolutionary distinctions between parent and emerging lines, suggesting a parallelism between duplicatory and mutational events, now also visible at separate sub-stages. Combined, all forms show distinctive patterns at different levels and illustrate correlations with global events. They further show that simple molecular observations on patterns, multiplicities and occurrence give much information, suggesting common divergence rules not much disturbed by horizontal gene transfers after the initial origins.

    The activity and the selectivity of Ru and Pt based carbon catalysts in the selective oxidation of long-chain aliphatic alcohols (C8, C10, C12) have been investigated. Ru/AC and Pt/AC always showed good initial activity, however deactivation phenomena rapidly depressed the catalytic per-formance of the catalysts. These phenomena can be limited by modification of Ru/AC and Pt/AC with Au improving the durability of the catalyst. Ru/AC and AuRu/AC showed good selectivity to the corresponding aldehyde (>95%) making these catalysts promising for fragrances manufactur-ing. The advantage in using Au modified catalyst lies on the easier regeneration procedure com-pared to the one necessary for Ru/AC. Pt/AC and AuPt/AC showed a lower selectivity to aldehyde promoting the formation of the acid and the ester formation respectively. The addition of water in the solvent system speeds up the reaction rate but drastically decreased the selectivity to aldehyde especially in the case of Pt based catalysts.

    Fatty alcohols are value-added chemicals and important components of a variety of industries, which have a >3 billion-dollar global market annually. Long chain fatty alcohols (>C12) are mainly used in surfactants, lubricants, detergents, pharmaceuticals and cosmetics while medium chain fatty alcohols (C6-C12) could be used as diesel-like biofuels. Microbial production of fatty alcohols from renewable feedstock stands as a promising strategy to enable sustainable supply of fatty alcohols. In this study, we report, for the first time, that medium chain fatty alcohols could be produced in yeast via targeted expression of a fatty acyl-CoA reductase (TaFAR) in the peroxisome of Saccharomyces cerevisiae. By tagging TaFAR enzyme with peroxisomal targeting signal peptides, the TaFAR could be compartmentalized into the matrix of the peroxisome to hijack the medium chain fatty acyl-CoA generated from the beta-oxidation pathway and convert them to versatile medium chain fatty alcohols (C10 &C12). The overexpression of genes encoding PEX7 and acetyl-CoA carboxylase further improved fatty alcohol production by 1.4-fold. After medium optimization in fed-batch fermentation using glucose as the sole carbon source, fatty alcohols were produced at 1.3 g/L, including 6.9% 1-decanol, 27.5% 1-dodecanol, 2.9% 1-tetradecanol and 62.7% 1-hexadecanol. This work revealed that peroxisome could be engineered as a compartmentalized organelle for producing fatty acid-derived chemicals in S. cerevisiae. PMID:27230732

    Wild-type Ralstonia eutropha H16 produces polyhydroxybutyrate (PHB) as an intracellular carbon storage material during nutrient stress in the presence of excess carbon. In this study, the excess carbon was redirected in engineered strains from PHB storage to the production of isobutanol and 3-methyl-1-butanol (branched-chain higher alcohols). These branched-chain higher alcohols can directly substitute for fossil-based fuels and be employed within the current infrastructure. Various mutant strains of R. eutropha with isobutyraldehyde dehydrogenase activity, in combination with the overexpression of plasmid-borne, native branched-chain amino acid biosynthesis pathway genes and the overexpression of heterologous ketoisovalerate decarboxylase gene, were employed for the biosynthesis of isobutanol and 3-methyl-1-butanol. Production of these branched-chain alcohols was initiated during nitrogen or phosphorus limitation in the engineered R. eutropha. One mutant strain not only produced over 180 mg/L branched-chain alcohols in flask culture, but also was significantly more tolerant of isobutanol toxicity than wild-type R. eutropha. After the elimination of genes encoding three potential carbon sinks (ilvE, bkdAB, and aceE), the production titer improved to 270 mg/L isobutanol and 40 mg/L 3-methyl-1-butanol. Semicontinuous flask cultivation was utilized to minimize the toxicity caused by isobutanol while supplying cells with sufficient nutrients. Under this semicontinuous flask cultivation, the R. eutropha mutant grew and produced more than 14 g/L branched-chain alcohols over the duration of 50 days. These results demonstrate that R. eutropha carbon flux can be redirected from PHB to branched-chain alcohols and that engineered R. eutropha can be cultivated over prolonged periods of time for product biosynthesis.

    Fatty aldehydes and alcohols are valuable precursors used in the industrial manufacturing of a myriad of specialty products. Herein, we demonstrate the de novo production of odd chain-length fatty aldehydes and fatty alcohols in Saccharomyces cerevisiae by expressing a novel biosynthetic pathway involving cytosolic thioesterase, rice α-dioxygenase and endogenous aldehyde reductases. We attained production titers of ∼20 mg/l fatty aldehydes and ∼20 mg/l fatty alcohols in shake flask cultures after 48 and 60 h respectively without extensive fine-tuning of metabolic fluxes. In contrast to prior studies which relied on bi-functional fatty acyl-CoA reductase to produce even chain-length fatty alcohols, our biosynthetic route exploits α-oxidation reaction to produce odd chain-length fatty aldehyde intermediates without using NAD(P)H cofactor, thereby conserving cellular resource during the overall synthesis of odd chain-length fatty alcohols. The biosynthetic pathway presented in this study has the potential to enable sustainable and efficient synthesis of fatty acid-derived chemicals from processed biomass. PMID:26461930

  19. Applying commodity chain analysis to changing modes of alcohol supply in a developing country.

    2000-12-01

    Development sociology has used global commodity chains as one way of analyzing the dynamics of power and profit-taking in globalized production networks made up of multiple firms and occurring in multiple national settings. A substantial portion of the alcohol supply in developing countries is now produced through such production networks. Particularly in the beer and spirits trade, a small number of transnational firms control networks of local producers, importers, advertisers and distributors. These networks serve to embed transnational or transnationally backed brands in the local culture, using the tools of market research, product design and marketing to influence local drinking practices. Case materials from Malaysia's beer industry help to illustrate how the transnational firms dominate in those links of the commodity chain in which monopoly or oligopoly control is most likely to be found: the design/recipe and marketing/advertising nodes. Their control of the commodity chains and extraction of monopoly or oligopoly profits from them places substantial resources and influence over drinking settings and practices in foreign hands. The impact of this influence on state efficacy and autonomy in setting alcohol policy is an important subject for future research on the creation and implementation of effective alcohol policies in developing societies.

    The effect of alcohol chain length, concentration and polarity on separation in high-performance liquid chromatography using beta-cyclodextrin-bonded silica is discussed. The results show that retention times cannot be predicted merely from the polarity of the binary mobile phase. Although organic modifiers with the same physico-chemical properties and from the same solvent group were used, the retention times obtained using binary mobile phases having the same polarity, were different. It was also observed that normal-chain carbon alcohols gave retention times shorter than those obtained with a branched-chain alcohol (n-propanol vs. isopropanol), and the longer the alcohol chain the shorter the retention times. A plot of ln k' vs. alcohol volume fraction for benzene, toluene, ethylbenzene, propylbenzene, butylbenzene, 1-phenylhexane and 1-phenyloctane gave a linear relationship in methanol, ethanol and propanol (except for 1-phenylhexane). A non-linear relationship was obtained for all the solutes in isopropanol, tert.-butanol and 1-butanol, in the alcohol volume fraction studied. PMID:2324212

  4. Synthesis of crystalline Cu2O nanoparticles using long chained alcohol

    International Nuclear Information System (INIS)

    The successful synthesis of highly crystallized cuprous oxide nanoparticles using long chained alcohol reduction method is reported. The purity of copper oxide obtained by this method greatly depends on the synthesis conditions such as reaction temperature, reaction duration, and hydroxyl ion concentration that assist the reduction kinetics. By optimizing the above parameters, cubic cuprous oxide with particle sizes controllable in the range of 10–30 nm were synthesized. The x-ray diffraction analysis confirmed the single-phased nature of Cu2O crystal. Furthermore, the ratio between copper and oxygen atoms in the product was determined to be 1.96 using the Rietveld analysis and confirmed the purity of Cu2O nanoparticles. In addition, I–V characteristics suggested that the nanoparticles function as semiconductor and indicated the use of these cuprous nanocrystals as a functional material for the preparation of solar devices.

    The primary structure of the gamma 1 subunit of human liver alcohol dehydrogenase isoenzyme gamma 1 gamma 1 was deduced by characterization of 36 tryptic and 2 CNBr peptides. The polypeptide chain is composed of 373 amino acid residues. gamma 1 differs from the beta 1 subunit of human liver alcohol dehydrogenase at 21 positions, and from the E subunit of horse liver alcohol dehydrogenase at 43 positions including a gap at position 128 as in the beta 1 subunit. All zinc-liganding residues from the E subunit of the horse protein and the beta 1 subunit of the human enzyme are conserved, but like beta 1, gamma 1 also has an additional cysteine residue at position 286 (in the positional numbering system of the horse enzyme) due to a Tyr----Cys exchange. Most amino acid exchanges preserve the properties of the residues affected and are largely located on the surface of the molecules, away from the active site and the coenzyme binding region. However, eight positions with charge differences in relation to the E subunit of the horse enzyme are noticed. These result in a net positive charge increase of one in gamma 1 versus E, explaining the electrophoretic mobilities on starch gels. Of functional significance is the conservation of Ser-48 in gamma 1 relative to E. The residue is close to the active site but different (Thr-48) in the beta 1 subunit of the human enzyme. Thus, the closer structural relationship between human gamma 1 and horse E enzyme subunit than between beta 1 and E is also reflected in functionally important residues, explaining a greater similarity between gamma 1 gamma 1 and EE than between beta 1 beta 1 and EE.

    A series of phase change materials (PCMs) based on long chain polyacrylate and 1-alcohol, i.e., poly (stearyl methacrylate) and 1-tetradecanol (PSMA/C14OH) were prepared through the solution-mixing method. Thermal energy storage capacity, thermal stability and morphology of PSMA/C14OH PCMs were characterized by Fourier transform infrared spectroscopy (FTIR), polarized optical microscopy (POM), field emission scanning electron microscopy (FE-SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). DSC results demonstrated that the heat of fusion of PSMA/C14OH PCMs increased from 85.9 to 172.3 J g−1 with the weight fraction of C14OH increasing from 20 to 80 wt%. And, the thermal stability also enhanced with PSMA weight. The spherulite (ca. 250 μm) in PSMA/C14OH composites containing 60 wt% C14OH proved the compatibility between PSMA and C14OH, indicating the cocrystallization behavior of alkyl side groups appeared. The cocrystallization behavior contributes the enhanced thermal stability of PSMA/C14OH PCMs, and it is suitable as the thermal energy storage materials in the future. - Highlights: • Heat storage capability of PSMA/C14OH PCMs increased with C14OH weight. • The spherulites exhibit the weight-dependence upon C14OH. • The thermal stability of PSMA/C14OH PCMs obviously improved

    Full Text Available Production of fatty acid esters from stearic, oleic, and palmitic acids and short-chain alcohols (methanol, ethanol, propanol, and butanol for the production of biodiesel was investigated in this work. A series of montmorillonite-based clays catalysts (KSF, KSF/0, KP10, and K10 were used as acidic catalysts. The influence of the specific surface area and the acidity of the catalysts on the esterification rate were investigated. The best catalytic activities were obtained with KSF/0 catalyst. The esterification reaction has been carried out efficiently in a semi-continuous reactor at 150°C temperature higher than the boiling points of water and alcohol. The reactor used enabled the continuous removal of water and esterification with hydrated alcohol (ethanol 95% without affecting the original activity of the clay.

    Gasification of organic wastes coupled to syngas fermentation allows the recovery of carbon in the form of commodity chemicals, such as carboxylates and biofuels. Acetogenic bacteria ferment syngas to mainly two-carbon compounds, although a few strains can also synthesize four-, and six-carbon molecules. In general, longer carbon chain products have a higher biotechnological (and commercial) value due to their higher energy content and their lower water solubility. However, de-novo synthesis of medium-chain products from syngas is quite uncommon in acetogenic bacteria. An alternative to de-novo synthesis is bioproduction of short-chain products (C2 and C4), and their subsequent elongation to C4, C6, or C8 through reversed β-oxidation metabolism. This two-step synergistic approach has been successfully applied for the production of up to C8 compounds, although the accumulation of alcohols in these mixed cultures remained below detection limits. The present work investigates the production of higher alcohols from syngas by open mixed cultures (OMC). A syngas-fermenting community was enriched from sludge of an anaerobic digester for a period of 109 days in a lab-scale reactor. At the end of this period, stable production of ethanol and butanol was obtained. C6 compounds were only transiently produced at the beginning of the enrichment phase, during which Clostridium kluyveri, a bacterium able to carry out carbon chain elongation, was detected in the community. Further experiments showed pH as a critical parameter to maintain chain elongation activity in the co-culture. Production of C6 compounds was recovered by preventing fermentation pH to decrease below pH 4.5–5. Finally, experiments showed maximal production of C6 compounds (0.8 g/L) and alcohols (1.7 g/L of ethanol, 1.1 g/L of butanol, and 0.6 g/L of hexanol) at pH 4.8. In conclusion, low fermentation pH is critical for the production of alcohols, although detrimental to C. kluyveri. Fine control of

  13. Quantum-chemical modeling of energy parameters and vibrational spectra of chain and cyclic clusters of monohydric alcohols

    International Nuclear Information System (INIS)

    The specific peculiarities of alcohols such as heightened viscosity, boiling temperature and surface tension can be explained by the capability of their molecules to form relatively stable associates named clusters due to hydrogen bonding. In present work the stability of different chain-like and cyclic clusters of methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol and 1-hexanol was investigated by means of quantum-chemical simulation and particular by recently developed DFT exchange–correlation functional M06-2X. The relative stability of the cluster structure was evaluated by the total energy per molecule at low temperatures (where all alcohols exist in solid state) and by the changing of the free Gibbs energy upon cluster formation at the room temperature. For the verification of revealed results the conformity of calculated IR spectra of the most stable cluster structures with the experimental IR spectra at different temperatures was analyzed.

    The fusel alcohols 3-methyl-1-butanol, 2-methyl-1-butanol, and 2-methyl-propanol are important flavor compounds in yeast-derived food products and beverages. The formation of these compounds from branched-chain amino acids is generally assumed to occur via the Ehrlich pathway, which involves the concerted action of a branched-chain transaminase, a decarboxylase, and an alcohol dehydrogenase. Partially purified preparations of pyruvate decarboxylase (EC 4.1.1.1) have been reported to catalyze the decarboxylation of the branched-chain 2-oxo acids formed upon transamination of leucine, isoleucine, and valine. Indeed, in a coupled enzymatic assay with horse liver alcohol dehydrogenase, cell extracts of a wild-type Saccharomyces cerevisiae strain exhibited significant decarboxylation rates with these branched-chain 2-oxo acids. Decarboxylation of branched-chain 2-oxo acids was not detectable in cell extracts of an isogenic strain in which all three PDC genes had been disrupted. Experiments with cell extracts from S. cerevisiae mutants expressing a single PDC gene demonstrated that both PDC1- and PDC5-encoded isoenzymes can decarboxylate branched-chain 2-oxo acids. To investigate whether pyruvate decarboxylase is essential for fusel alcohol production by whole cells, wild-type S. cerevisiae and an isogenic pyruvate decarboxylase-negative strain were grown on ethanol with a mixture of leucine, isoleucine, and valine as the nitrogen source. Surprisingly, the three corresponding fusel alcohols were produced in both strains. This result proves that decarboxylation of branched-chain 2-oxo acids via pyruvate decarboxylase is not an essential step in fusel alcohol production. PMID:9546164

  18. Dielectric studies of hydrogen bonded complexes tri-n-butyl phosphate (TBP) with long-chain aliphatic alcohols

    International Nuclear Information System (INIS)

    The mechanism of dipolar complexation involving TBP and three long chain aliphatic alcohols namely 1-hexanol, 1-heptanol, 1-octanol in a non-polar medium (benzene) was investigated from dielectric measurements at frequency 455 kHz and at temperature 303.16 K using modified Palit's method. The dipole moment of the complex (μbc), interaction dipole moment (Δμ), dipole moment of the H-bonded bridge (μ*) and induced polarization (ΔP) for the thermodynamically most favoured geometry of 1:1 complexes of these systems were computed. The results shows that complexation is due to partial proton transfer in all the cases studied and the tendency of complex formation is maximum in 1-heptanol system. (author)

    Confirmations of 2,4-dihydroxypentane (DHP), a model molecule for poly(vinyl alcohol), have been studied by quantum chemistry (QC) calculations and molecular dynamics (MD) simulations. QC calculations at the 6-311G MP2 level show the meso tt conformer to be lowest in energy followed by the racemic tg, due to intramolecular hydrogen bond between the hydroxy groups. The Dreiding force field has been modified to reproduce the QC conformer energies for DHP. MD simulations using this force field have been carried out for DHP molecules in the gas phase, melt, and CHCl3 and water solutions. Extensive intramolecular hydrogen bonding is observed for the gas phase and CHCl3 solution, but not for the melt or aqueous solution, Such a condensed phase effect due to intermolecular interactions results in a drastic change in chain conformations, in agreement with experiments.

  1. Study of surface tension and surface properties of binary systems of DMSO with long chain alcohols at various temperatures

    International Nuclear Information System (INIS)

    Highlights: • Surface tension of binary mixtures of alcohol/DMSO determined. • Surface mole fraction and surface thermodynamic parameters were calculated. • The surface tension data of binary mixtures were correlated with FLW, LWW and MS models. -- Abstract: Surface tensions of binary mixtures of DMSO (dimethyl sulphoxide) with a series of long chain aliphatic alcohols (1-propanol, 1-butanol, and 1-hexanol) were measured as a function of composition using the ring detachment method in the temperature range between (288.15 and 328.15) K. The surface tension results are used to describe quantitatively the nature, properties, and compositions of surface layers in binary liquid mixtures. The temperature influence on the behaviour of surface tensions and surface properties of binary mixtures has often been used to obtain information about solute structural effects on DMSO. The surface tension of the above mentioned binary systems were correlated with empirical and thermodynamic based models. The average relative error obtained from the comparison of experimental and calculated surface tension values for 15 binary systems with three models is less than 1%. In addition to finding more information about the surface structure of binary mixtures, surface mole fraction was calculated using an extended Langmuir model (EL). The temperature dependence of σ at fixed composition of solutions was used to estimate surface enthalpy, Hs, and surface entropy, Ss. The results provide information on the molecular interactions between the unlike molecules that exist at the surface and the bulk

    Highlights: • ρ and u have been measured for binary mixtures of benzylalcohol with 1-alkanols. • Experimental speed of sound data analyzed in terms of CFT and FLT. • VE for benzylalcohol with studied 1-alcohols are positive while κSE are negative. - Abstract: Densities (ρ) of pure liquids and their mixtures have been measured over the entire composition range for the binary mixtures of benzylalcohol with 1-heptanol, 1-octanol, 1-nonanol and 1-decanol at 298.15 K to 313.15 K and at atmospheric pressure by using Rudolph Research Analytical Digital Density Meter (DDM-2911 model). Further, the speed of sound (u) for the above said mixtures were also measured at 303.15 K and 313.15 K. The experimental density data were used to compute excess molar volumes (VE) and compared with predictive expression proposed by Redlich–Kister equation. Excess speed of sound (uE), isentropic compressibility (κS) and excess isentropic compressibilities (κSE) were evaluated from experimental sound velocity and density data. Moreover, the experimental speed of sound data was compared in terms of theoretical models proposed by Schaaff's collision factor theory (CFT) and Jacobson's free length theory (FLT). The experimental results were discussed in terms of intermolecular interactions between component molecules

    Chemical group 2 consists of branched-chain primary aliphatic alcohols/aldehydes/acids, acetals and esters with esters containing branched-chain alcohols and acetals containing branched-chain aldehydes, of which 34 are currently authorised for use as flavours in food. The use of 2-methylpropionic acid, isopentyl acetate, 3-methylbutyl butyrate and 2-methylbutyl acetate is safe at the proposed use level of 25 mg/kg complete feed for cattle, salmonids and non food producing animals and at 5 mg/kg complete feed for pigs and poultry. 2-Methylpropan-1-ol, isopentanol, 2-ethylhexan-1-ol, 2-methylpropanal, 3-methylbutanal, 2-methylbutyraldehyde, 3-methylbutyric acid, 2-methylvaleric acid, 2-ethylbutyric acid, 2-methylbutyric acid, 2-methylheptanoic acid, 4-methyloctanoic acid, isobutyl acetate, isobutyl butyrate, 3-methylbutyl propionate, 3-methylbutyl formate, glyceryl tributyrate, isobutyl isobutyrate, isopentyl isobutyrate, isobutyl isovalerate, isopentyl 2-methylbutyrate, 2-methylbutyl isovalerate and 2-methylbutyl butyrate are safe at the proposed use level of 5 mg/kg complete feed for all animal species. 3,7-Dimethyloctan-1-ol, 2-methylundecanal, 4-methylnonanoic acid, 3-methylbutyl hexanoate, 3-methylbutyl dodecanoate, 3-methylbutyl octanoate and 3-methylbutyl 3-methylbutyrate are safe at a maximum of 1.5 mg/kg complete feed for cattle, salmonids and non food-producing animals and of 1.0 mg/kg complete feed for pigs and poultry. No safety concern was identified for the consumer from the use of these compounds up to the highest safe level in feedingstuffs for all animal species. All compounds should be considered as irritants to skin, eyes and respiratory tract, and as skin sensitisers. The compounds do not pose a risk to the environment when used at concentrations considered safe for the target species. Since all compounds are used in food as flavourings, no further demonstration of efficacy is necessary.

It has been established that the influence of the sulphuric acid concentration on rhenium solvent extraction is largely due to the extraction process mechanism. In the case of the anion-exchange mechanism, ReO4- is best extracted from weakly acidic solutions, whereas when the hydrate-solvate mechanism takes place – from solutions containing 4-7 mole/l H2SO4.

    Zygosaccharomyces rouxii, a salt-tolerant yeast isolated from the soy sauce process, produces fusel alcohols (isoamyl alcohol, active amyl alcohol and isobutyl alcohol) from branched-chain amino acids (leucine, isoleucine and valine, respectively) via the Ehrlich pathway. Using a high-throughput screening approach in microtiter plates, we have studied the effects of pH, temperature and salt concentration on growth of Z. rouxii and formation of fusel alcohols from branched-chain amino acids. Application of minor variations in pH (range 3-7) and NaCl concentrations (range 0-20%) per microtiter plate well allowed a rapid and detailed evaluation of fermentation conditions for optimal growth and metabolite production. Conditions yielding the highest cell densities were not optimal for fusel alcohol production. Maximal fusel alcohol production occurred at low pH (3.0-4.0) and low NaCl concentrations (0-4%) at 25 degrees C. At pH 4.0-6.0 and 0-18% NaCl, considerable amounts of alpha-keto acids, the deaminated products from the branched-chain amino acids, accumulated extracellularly. The highest cell densities were obtained in plates incubated at 30 degrees C. The results obtained under various incubation conditions with (deep-well) microtiter plates were validated in Erlenmeyer shake-flask cultures. PMID:12689638

  8. Activities of the enzymes of the Ehrlich pathway and formation of branched-chain alcohols in Saccharomyces cerevisiae and Candida utilis grown in continuous culture on valine or ammonium as sole nitrogen source.

    Valine aminotransferase, a key enzyme in both biosynthesis and breakdown of branched-chain amino acids, showed consistently higher activity in Candida utilis grown in continuous culture than in Saccharomyces cerevisiae, while pyruvate decarboxylase and alcohol dehydrogenase, the other two enzymes of the Ehrlich pathway of branched-chain alcohol formation, were lower in activity. By spheroplast lysis, it was shown that valine aminotransferase followed the distribution of pyruvate decarboxylase in being located in the cytosol. Replacement of ammonium as nitrogen source by valine during conditions of carbon or nitrogen limitation caused increased specific activities of these three enzymes in S. cerevisiae, but (with one exception) decreased those of C. utilis. Of the metabolites accumulating in the culture medium, little or no ethanol or branched-chain alcohols were present during carbon-limited growth of either organism, but the change to nitrogen limitation resulted in increases in concentration of 20- to 100-fold in pyruvate, acetate and non-pyruvate keto acids as well as the accumulation of branched-chain alcohols in both organisms, and of ethanol, ethyl acetate and glycerol in S. cerevisiae. When valine was the limiting nitrogen source, there was an increase in non-pyruvate keto acids and a 10- to 16-fold increase in 2-methylpropanol. Total branched-chain alcohols formed under nitrogen limitation were 2-fold higher in S. cerevisiae than in C. utilis, irrespective of nitrogen source. Accumulation of branched-chain alcohols, ethanol, acetate and glycerol was also observed during carbon-limited growth of S. cerevisiae with valine as nitrogen source at dilution rates above the critical rate for transition to respirofermentative growth. Less than 70% of the valine carbon metabolized during growth of S. cerevisiae and only 15% of that used during growth of C. utilis was recovered in identified metabolic products. Even allowing for losses by volatilization during

    To understand the molecular mechanisms that control seed formation, we selected a seed-preferential gene (CvADH1) from the ESTs of developing watermelon seeds. RNA blot analysis and in situ localization showed that CvADH1 was preferentially expressed in the nucellar tissue. The CvADH1 protein shared about 50% homology with short-chain alcohol dehydrogenase including ABA2 in Arabidopsis thaliana, stem secoisolariciresinol dehydrogenase in Forsythia intermedia, and 3beta-hydroxysterol dehydrogenase in Digitalis lanata. We investigated gene-expression levels in seeds from both normally pollinated fruits and those made parthenocarpic via N-(2-chloro-4-pyridyl)-N'-phenylurea treatment, the latter of which lack zygotic tissues. Whereas the transcripts of CvADH1 rapidly started to accumulate from about the pre-heart stage in normal seeds, they were not detectable in the parthenocarpic seeds. Treating the parthenogenic fruit with GA(3) strongly induced gene expression, up to the level accumulated in pollinated seeds. These results suggest that the CvADH1 gene is induced in maternal tissues by signals made in the zygotic tissues, and that gibberellin might be one of those signals. We also observed that CvADH1 expression was induced by sucrose in the parthenocarpic seeds. Therefore, we propose that the CvADH1 gene is inducible by gibberellin, and that sucrose plays an important role in the maternal tissues of watermelon during early seed development. PMID:12552151

    Multiple sclerosis is a neurological disorder with poorly understood pathogenic mechanisms and a lack of effective therapies. Therefore, the search for new MS treatments remains very important. This study was performed on a commonly used cuprizone animal model of multiple sclerosis. It evaluated the effect of a plant-derived substance called Ropren® (containing approximately 95% polyprenols or long-chain isoprenoid alcohols) on cuprizone- induced demyelination. The study was performed on 27 eight-week old male CD-1 mice. To induce demyelination mice were fed 0.5% cuprizone in the standard diet for 10 weeks. Ropren® was administered in one daily intraperitoneal injection (12mg/kg), beginning on the 6th week of the experiment. On the 11th week, the corpus callosum in the brain was evaluated in all animals using magnetic resonance imaging with an 11.7 T animal scanner using T2- weighted sequence. Cuprizone treatment successfully induced the model of demyelination with a significant decrease in the size of the corpus callosum compared with the control group (p<0.01). Mice treated with both cuprizone and Ropren® did not exhibit demyelination in the corpus callosum (p<0.01). This shows the positive effect of polyprenols on cuprizone-induced demyelination in mice.

    A new family of neutral alcohol-soluble small molecular materials comprised of electron-rich triphenylamine (TPA) and fluorene featuring phosphonate side chains (FEP) is reported, namely 3TPA-FEP, 2TPA-2FEP and TPA-3FEP, which have different TPA and FEP contents. Due to their good solubility in polar solvents like alcohol, multilayer devices can be fabricated by a wet process from orthogonal solvents. Polymer light-emitting devices with these materials as a cathode interlayer and Al as the cathode show greatly enhanced efficiencies in contrast to control devices without such a cathode interlayer, and their efficiencies are comparable with or even higher than devices with the low work-function metal Ba/Al as the cathode. In addition, high-performance polymer solar cells based on the poly[N-9''-hepta-decanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT):[6,6]-phenyl C71 -butyric acid methyl ester (PC71 BM) system are also achieved with power conversion efficiencies of 7.21%, 6.90% and 6.89%, by utilizing 3TPA-FEP, 2TPA-2FEP and TPA-3FEP as the cathode interlayer, respectively. These efficiencies are also much higher than those for control devices without the cathode interlayer. Although TPA is well-known as a hole-transport unit, the current findings indicate that alcohol-soluble TPA-based small molecules are also a promising cathode interlayer for both electron injection and extraction.

  20. Enthalpies of reaction, formation, and hydrogenation among long chain alkanes, monoalkenes, acids, alcohols, and amines: G4 computed and experimental results

    International Nuclear Information System (INIS)

    Highlights: • We present a comparison of 59 G4 calculations with experimental results. • Enthalpies of formation, isomerization, and hydrogenation are covered. • Linear functions for experiment and calculation lead to a linear conversion function. • Results are given for alkanes, alkenes, acids, alcohols, and amines. - Abstract: We have carried out a comparison of experimental results and 59 G4 calculations of the enthalpies of formation ΔfH298Ko and hydrogenation ΔhydH298Ko of alkenes from 4 to 12 carbon atoms. We present a systematic calculation of the cis–trans isomerization enthalpy and a systematic comparison of experimental enthalpies of hydrogenation determined in this laboratory with the computed results of the same hydrogenations. The linear function of experimental results for alkanes and the linear function of the computed values lead to a linear function for converting one to the other. This result is an alternative to the commonly-used “atomization method” for finding the enthalpy of formation of an alkane relative to the thermodynamic reference state of the elements in their standard states. We calculate results in vector and matrix representation for compactness and consistency in treating large sets of computed G4 results. We show that the methods given here are sufficiently accurate so that reliable extrapolations to larger molecules can be made and that they are applicable to acids of biological interest, to alcohols, amines, and, in principle, to many other compounds such as polyenes, alkynes, and substituted alkanes

  4. Quadruple signal amplification strategy based on hybridization chain reaction and an immunoelectrode modified with graphene sheets, a hemin/G-quadruplex DNAzyme concatamer, and alcohol dehydrogenase: ultrasensitive determination of influenza virus subtype H7N9

    International Nuclear Information System (INIS)

    We report on a new amplification strategy for use in an immunoassay for influenza virus subtype H7N9. Graphene sheets were first placed on a glassy carbon electrode (GCE), and gold nanoparticles were then electrodeposited as a support for a layer of alcohol dehydrogenase (ADH) in a sol–gel containing thiol groups. Protein A was used to properly orientate immobilized antibody against H7N9 on the sol–gel, and this is shown to result in strongly improved specificity of the antigen-antibody binding. Thus, a sensitive and specific immunosensor was obtained in which a quadruple signal amplification strategy is employed, viz. (a) via the use of graphene sheets, (b) via a hybridization chain reaction, (c) the use of hemin/G-quadruplex DNAzyme concatamers, and (d) the use of ADH. The hemin/G-quadruplex is a typical DNAzyme, which simultaneously acts as NADH oxidase and HRP-mimicking DNAzyme. The hybridization chain reaction-based DNAzyme concatamers assembled on multi-walled carbon nanotubes (MWCNTs) and the ADH represent a triple electrocatalytic enzyme cascade system. Sandwich immunoreactions occurred between the capture antibody on the electrode and the secondary antibody labeled with MWCNTs. Positively charged Methylene Blue (MB) was then used as an intercalator to detect the DNAzyme concatamer formed. The differential pulse voltammetric signals for MB are related to the concentration of H7N9 in the range from 8 to 60 pg · mL−1, and the detection limit is 0.81 pg · mL−1 (at an S/N ratio of 3). This immunoassay is very sensitive, specific and robust. (author)

    Full Text Available Chemical group 1 (CG 1 consists of straight-chain primary aliphatic alcohols/aldehydes/acids, acetals and esters with esters containing saturated alcohols and acetals containing saturated aldehydes of which 86 are currently authorised for use as flavours in food. The FEEDAP Panel was unable to perform an assessment of ethyl oleate because of its insufficient purity. The following compounds are considered to be safe for all animal species at the use level proposed for feed flavourings: formic acid, acetic acid, propionic acid, octanoic acid, decanoic acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid, oleic acid, decanol, dodecanol, decyl acetate and dodecyl acetate. The remaining substances are considered safe for all animal species at 5 mg/kg complete feed (with a margin of safety between 1 and 120 and at 25 mg/kg complete feed (ethyl acetate and hexyl acetate, with a margin of safety between 2 and 6; and at 1 mg/kg complete feed for pigs and poultry and 1.5 mg/kg complete feed for all other species (ethylacrylate, ethyl hex-3-enoate, ethyl trans-2-butenoate, ethyl isobutyrate, ethyl isovalerate, butyl isovalerate, methyl isovalerate, hexyl isobutyrate, methyl 2-methyl butyrate, pentyl isovalerate, butyl 2-methyl butyrate, hexyl isovalerate, ethyl 2-methyl butyrate, hexyl 2-methyl butyrate and methyl 2-methylvalerate. No safety concern would arise for the consumer from the use of compounds belonging to CG 1 up to the highest safe level in feedingstuffs for all animal species. The FEEDAP Panel considers it prudent to treat all compounds under assessment as irritants to skin, eyes and respiratory tract and as skin sensitizers. No risk for the safety for the environment is foreseen. Since all 85 compounds are used in food as flavourings, no further demonstration of efficacy is necessary.

    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.

    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.

    Alcohol oxidases (Alcohol: O₂ Oxidoreductase; EC 1.1.3.x) are flavoenzymes that catalyze the oxidation of alcohols to the corresponding carbonyl compounds with a concomitant release of hydrogen peroxide. Based on substrate specificity, alcohol oxidases may be categorized broadly into four different groups namely, (a) short chain alcohol oxidase (SCAO), (b) long chain alcohol oxidase (LCAO), (c) aromatic alcohol oxidase (AAO), and (d) secondary alcohol oxidase (SAO). The sources reported for these enzymes are mostly limited to bacteria, yeast, fungi, plant, insect, and mollusks. However, the quantum of reports for each category of enzymes considerably varies across these sources. The enzymes belonging to SCAO and LCAO are intracellular in nature, whereas AAO and SAO are mostly secreted to the medium. SCAO and LCAO are invariably reported as multimeric proteins with very high holoenzyme molecular masses, but the molecular characteristics of these enzymes are yet to be clearly elucidated. One of the striking features of the alcohol oxidases that make them distinct from the widely known alcohol dehydrogenase is the avidly bound cofactor to the redox center of these enzymes that obviate the need to supplement cofactor during the catalytic reaction. These flavin-based redox enzymes have gained enormous importance in the development of various industrial processes and products primarily for developing biosensors and production of various industrially useful carbonyl compounds. The present review provides an overview on alcohol oxidases from different categories focusing research on these oxidases during the last decade along with their potential industrial applications.

    2012-01-01

    SUMMARY This study explores relationships between young adult restaurant employees' understanding and compliance with workplace alcohol control policies and consequences of alcohol policy violation. A mixed method analysis of 67 semi-structured interviews and 1,294 telephone surveys from restaurant chain employees found that alcohol policy details confused roughly a third of employees. Among current drinkers (n=1,093), multivariable linear regression analysis found that frequency of alcohol policy violation was positively associated with frequency of experiencing problems at work; perceived supervisor enforcement of alcohol policy was negatively associated with this outcome. Implications for preventing workplace alcohol-related problems include streamlining confusing alcohol policy guidelines. PMID:22984360

    BACKGROUND AND OBJECTIVE Internet alcohol marketing is not well studied despite its prevalence and potential accessibility and attractiveness to youth. The objective was to examine longitudinal associations between self-reported engagement with Internet alcohol marketing and alcohol use transitions in youth. METHODS A US sample of 2012 youths aged 15 to 20 was surveyed in 2011. An Internet alcohol marketing receptivity score was developed, based on number of positive responses to seeing alcohol advertising on the Internet, visiting alcohol brand Web sites, being an online alcohol brand fan, and cued recall of alcohol brand home page images. We assessed the association between baseline marketing receptivity and both ever drinking and binge drinking (≥6 drinks per occasion) at 1-year follow-up with multiple logistic regression, controlling for baseline drinking status, Internet use, sociodemographics, personality characteristics, and peer or parent drinking. RESULTS At baseline, ever-drinking and binge-drinking prevalence was 55% and 27%, respectively. Many (59%) reported seeing Internet alcohol advertising, but few reported going to an alcohol Web site (6%) or being an online fan (3%). Higher Internet use, sensation seeking, having family or peers who drank, and past alcohol use were associated with Internet alcohol marketing receptivity, and a score of 1 or 2 was independently associated with greater adjusted odds of initiating binge drinking (odds ratio 1.77; 95% confidence interval, 1.13–2.78 and odds ratio 2.15; 95% confidence interval, 1.06–4.37 respectively) but not with initiation of ever drinking. CONCLUSIONS Although high levels of engagement with Internet alcohol marketing were uncommon, most underage youths reported seeing it, and we found a prospective association between receptivity to this type of alcohol marketing and future problem drinking, making additional research and ongoing surveillance important.

    Alcohol dependence and abuse is one of the most costly health problems in the world from both a social and an economic point of view. It is a widespread problem, focusing attention not only psychiatrists but also doctors of other specialties. Patterns of drinking appear to be changing throughout the world, with more women and young people drinking heavily. Even risky drinking is a potential health risk, while chronic alcohol abuse contribute to the serious physical and mental complications. Alcohol used disorders associated with alcohol-induced brain damage include: withdrawal state, delirium tremens, alcoholic hallucinosis, alcoholic paranoia, Korsakoffs psychosis, alcoholic dementia, alcoholic depression. On the other hand, mental disorders as panic disorder, social anxiety disorder, agoraphobia, depression, bipolar disorder, schizophrenia, personality disorder most frequently comorbid with alcohol abuse or they trigger alcohol.

    In the present study, the effects of operating conditions on biocatalytic activity and stability of Novozym 435 for repeated-batch biodiesel production from free fatty acid (FFA) were investigated. Thermal deactivation caused by increased operating temperature from 45 to 50 °C could seriously affect the reusability of Novozym 435. The deactivation of Novozym 435 during the esterification of oleic acid with ethanol tended to be stronger than that in the system with methanol. Under the optimal conditions, considering both biocatalytic activity and stability of the enzyme, Novozym 435 could be reused for 13 cycles for biodiesel productions from oleic acid and absolute alcohols (methanol and ethanol) with FFA conversions of at least 90%. The presence of 4%–5%water in ethanol significantly affected the reusability of Novozym 435. Changes in the surface morphology of Novozym 435 during the esterification with various conditions were observed. It was revealed that the reduc-tion in catalytic activity was related to the swel ing degree of the catalyst surface. Additionally, biodiesel produc-tion from low cost renewable feedstocks, such as palm fatty acid distillate (PFAD) and 95%ethanol was examined. The esterification of PFAD with 95%ethanol catalyzed by Novozym 435 in 10-repeated batch operation showed the similar results in FFA conversion as compared to those using oleic acid. Novozym 435 remained active and could maintain 97.6%of its initial conversion after being used for 10 batches.

    Background Alcohol intoxication can increase inflammation and worsen injury, yet the mechanisms involved are not clear. We investigated whether acute alcohol intoxication elevates microvascular permeability, and investigated potential signaling mechanisms in endothelial cells that may be involved. Methods Conscious rats received a 2.5 g/kg alcohol bolus via gastric catheters to produce acute intoxication. Microvascular leakage of intravenously administered FITC-albumin from the mesenteric microcirculation was assessed by intravital microscopy. Endothelial-specific mechanisms were studied using cultured endothelial cell monolayers. Transendothelial electrical resistance (TER) served as an index of barrier function, before and after treatment with alcohol or its metabolite acetaldehyde. Pharmacologic agents were used to test the roles of alcohol metabolism, oxidative stress, p38 mitogen-activated protein (MAP) kinase, myosin light chain kinase (MLCK), rho kinase (ROCK), and exchange protein activated by cAMP (Epac). VE-cadherin localization was investigated to assess junctional integrity. Rac1 and RhoA activation were assessed by ELISA assays. Results Alcohol significantly increased FITC-albumin extravasation from the mesenteric microcirculation. Alcohol also significantly decreased TER and disrupted VE-cadherin organization at junctions. Acetaldehyde significantly decreased TER, but inhibition of ADH or application of a superoxide dismutase mimetic failed to prevent alcohol-induced decreases in TER. Inhibition of p38 MAP kinase, but not MLCK or ROCK, significantly attenuated the alcohol-induced barrier dysfunction. Alcohol rapidly decreased GTP-bound Rac1 but not RhoA during the drop in TER. Activation of Epac increased TER, but did not prevent alcohol from decreasing TER. However, activation of Epac after initiation of alcohol-induced barrier dysfunction quickly resolved TER to baseline levels. Conclusions Our results suggest that alcohol intoxication increases

    Full Text Available Studies have shown that excessive alcohol consumption impacts the intestinal microbiota composition, causing disruption of homeostasis (dysbiosis. However, this observed change is not indicative of the dysbiotic intestinal microbiota function that could result in the production of injurious and toxic products. Thus, knowledge of the effects of alcohol on the intestinal microbiota function and their metabolites is warranted, in order to better understand the role of the intestinal microbiota in alcohol associated organ failure. Here, we report the results of a differential metabolomic analysis comparing volatile organic compounds (VOC detected in the stool of alcoholics and non-alcoholic healthy controls. We performed the analysis with fecal samples collected after passage as well as with samples collected directly from the sigmoid lumen. Regardless of the approach to fecal collection, we found a stool VOC metabolomic signature in alcoholics that is different from healthy controls. The most notable metabolite alterations in the alcoholic samples include: (1 an elevation in the oxidative stress biomarker tetradecane; (2 a decrease in five fatty alcohols with anti-oxidant property; (3 a decrease in the short chain fatty acids propionate and isobutyrate, important in maintaining intestinal epithelial cell health and barrier integrity; (4 a decrease in alcohol consumption natural suppressant caryophyllene; (5 a decrease in natural product and hepatic steatosis attenuator camphene; and (6 decreased dimethyl disulfide and dimethyl trisulfide, microbial products of decomposition. Our results showed that intestinal microbiota function is altered in alcoholics which might promote alcohol associated pathologies.

    Natural products have a long history of use in traditional medicines and their activities against different diseases have been the focus of many basic and clinical researches in past few decades. The essential oils, volatile liquid containing aroma compound from plants, are known as active ingredients in the herbal medicine. Perillyl alcohol (POH) is usually available through dietary sources and is being explored for its cancer chemoprevention, tumor growth suppression, and regression. Citrus peels are the waste product of juice manufacturing industries and have been considered as a critical problem for environmental green ecology policies for years. One of the most well-known approaches to overcome this problem is transformation of these monoterpene by the use of specific strains of bacteria or yeasts. Limonene (1-methyl-4-isopropyl-cyclohexene) is a monoterpene, as other monoterpenes consists of two isoprene units, that comprises more than 90% of citrus essential oil and it exists in many fruits and vegetables. Although, the anticancer activity of d-limonene has identified nearly two decades ago, it has recently attracted much more attention in translational medicine. In this chapter, we will overview the anticancer effects of POH and d-limonene. Later, we will address the pharmacokinetics of these compounds, highlight the signaling pathways which are targeted by these proteins, review the clinical trials which have been done for these compounds in different cancer models, and finally discuss the future directions of the research in this field that might be more applicable in future cancer therapy strategies.

  13. Chain reaction

    International Nuclear Information System (INIS)

    Chain Reaction is a work of recent American political history. It seeks to explain how and why America came to depend so heavily on its experts after World War II, how those experts translated that authority into political clout, and why that authority and political discretion declined in the 1970s. The author's research into the internal memoranda of the Atomic Energy Commission substantiates his argument in historical detail. It was not the ravages of American anti-intellectualism, as so many scholars have argued, that brought the experts back down to earth. Rather, their decline can be traced to the very roots of their success after World War II. The need to over-state anticipated results in order to garner public support, incessant professional and bureaucratic specialization, and the sheer proliferation of expertise pushed arcane and insulated debates between experts into public forums at the same time that a broad cross section of political participants found it easier to gain access to their own expertise. These tendencies ultimately undermined the political influence of all experts. (author)

    [figure removed for brevity, see original site] The large crater at the top of this THEMIS visible image has several other craters inside of it. Most noticeable are the craters that form a 'chain' on the southern wall of the large crater. These craters are a wonderful example of secondary impacts. They were formed when large blocks of ejecta from an impact crashed back down onto the surface of Mars. Secondaries often form radial patterns around the impact crater that generated them, allowing researchers to trace them back to their origin.Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.

    Fetal alcohol syndrome is often associated with severe physical and neuropsychiatric maldevelopment. On the other hand, some offspring of women who drank during pregnancy appear to be affected in minimal ways and function relatively well within society. We questioned whether this effect of prenatal alcohol in the adult is generally minimal. To bear on this, we determined whether we could distinguish alcohol-exposed from nonexposed individuals in a population of male veterans, selected because of both their accepted level of function within society (e.g., honorable discharge from the military) and their admission to an alcohol treatment unit (thus, a greater likelihood of parental alcoholism, because of its familial aggregation). Consecutively admitted alcoholics (cases; n = 77) with likely maternal alcohol ingestion during their pregnancy or the first 10 years of life were matched with alcoholics with no maternal alcohol exposure during these periods (controls; n = 161). Each subject completed questionnaires regarding personal birthweight, alcohol, drug, educational and work histories, and family (including parental) alcohol and drug histories. We measured height, weight, and head circumference; checked for facial and hand anomalies; and took a frontal facial photograph, from which measurements of features were made. Data were analyzed by univariate statistics and stepwise logistic regression. No case had bona fide fetal alcohol syndrome. With univariate statistical analyses, the cases differed from the controls in 10 variables, including duration of drinking, width of alae nasae, being hyperactive or having a short attention span, and being small at birth. By stepwise logistic regression, the variables marital status, small size at birth, duration of drinking, and the presence of a smooth philtrum were marginally (the first two) or definitely (the last two) significant predictors of case status. Analysis of only the 37 cases in whom maternal prenatal drinking was

    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.

These techniques have allowed to prepare 1(R=Me, Et, i-Pr) and 2(R=Me, Et) with 70-98 % yield. Methylates are also prepared at ether interchange of ethylates by methyl alcohol. Metal anode oxidation in corresponding alcohol may be used for 1 synthesis. Physicochemical properties of both series alcoholates, solubility in alcohols in particular, depend on their formation conditions coordination polymerism. Alcoholates of 1 are rather unstable and tend to decomposition up to 2 and ether. It is suggested to introduce NaOR microquantities to stabilize those alcoholates

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

    [Objective] fao1 encods a iron-containing long-chain fatty alcohol oxidase in C.cloacae. By constructing the nuclear expression vector, according to the biological activity of protein we can judge whether fao1 can take full advantage of iron in Chlamydomonas reinhardtii chloroplast. Meanwhile it will provide a new direction for researches on the gene of iron-containing proteins.[Method]The PsaD transit peptide gene(TP), C. cloacae fatty-alcohol oxidase (fao1) gene and His-tag were cloned separately by polymerase chain reaction (PCR). The 3-piece fusion gene TFHis was inserted into pDBle. This construct was transformed into C. reinhardtii CW15 by glass beads method. The transgenic Chlamydomonas was obtained under the selection of zeocin and they were confirmed positive by PCR amplification and RT-PCR. The activity of the purified recombinant protein was tested by a color-linked assay.[Result]The correctness of the constructed pDBle-TFHis was confirmed by DNA sequencing. PCR and RT-PCR analysis of the genomic DNA and RNA from transgenic Chlamydomonas showed that the recombinant plasmid has been integrated into C. reinhardtii CW15 genome and transcribed successfully. Protein purification elution made substrate reaction turn blue.[Conclusion]In this study, fao1-bearing nuclear expression vector pDBle-TFHis was correctly constructed and integrated into C. reinhardtii CW15 genome and fao1 transcript was detected successfully. The recombinant protein was purified by an affinity column and the activity was tested.%[目的]fao1编码Candidacloacae中一种含铁辅基的长链脂肪醇氧化酶。通过构建该基因的衣藻核转化表达载体进行转化,根据表达蛋白的生物活性判断fao1能否充分利用衣藻叶绿体中的铁元素行使功能;同时也为需铁固氮酶基因的研究提供方向。[方法]通过PCR把PsaD信号肽、fao1、His-tag标签融合,连接到pDBle载体上;采用玻璃珠转化法,将重组子导入莱茵衣藻(CW15

    2010-01-01

    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.

    The adverse effects of prenatal alcohol consumption have long been known; however, a formal description and clinical diagnosis of these effects was not introduced until 1973. Since then, the distinction of the wide range of effects that can be induced by prenatal alcohol exposure, and, consequently, the terminology to describe these effects has continued to evolve. Although much progress has been made in understanding the consequences of prenatal alcohol exposure, challenges still remain in p...

  14. Alcohol-Induced Blackout

    Dai Jin Kim

    2009-11-01

    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.

    An overusing and an addiction to alcoholic drinks are important problems in a medical society. The studies made in the United States had documented that about 8-12% doctors were addicted to alcohol. In many cases the doctors are able to keep their problem as a secret and their activity is satisfied up to the moment when a decrease is noticed. Some factors--such as a high level of stress--predispose doctors to alcoholic problems especially surgeons. Alcohol problems should be identified as early as possible, and therapy ought to be given as well. There is no reason to hide the problem. PMID:19025048

    Special problems in the treatment of alcoholism are discussed. Risk groups, for instance children of alcoholics, should be identified as early as possible so that special attention can be paid to them. Treatment motivation plays a very central role, and motivating a patient for long-term treatment often is the most difficult part of the work. For alcohol dependent alcoholics, total abstinence should be the goal of treatment. To achieve this, psychotherapy consisting of supportive, behavioral and dynamic elements is recommended. To achieve effective therapy it should be carried out for a considerable length of time. PMID:8032164

    Alcohol abuse has been associated with an increased mortality and morbidity due to increased aspiration, delirium tremens, and seizures. The association of pneumococcal lung infections and leukopenia in the setting of alcohol abuse are rarely reported; however, when present, severe lung infections can happen with severe lung injury and poor response to conventional therapy and ultimately, death. We are reporting a case of 55-year-old-man presented with shortness of breath, cough and altered mental status and eventually found with severe pneumococcal lung infection in the setting of leukopenia and long-term alcohol abuse representing alcoholic leukopenic pneumococcal sepsis syndrome.

    Normal fatty aldehyde and alcohol metabolism is essential for epidermal differentiation and function. Long-chain aldehydes are produced by catabolism of several lipids including fatty alcohols, sphingolipids, ether glycerolipids, isoprenoid alcohols and certain aliphatic lipids that undergo α- or ω-oxidation. The fatty aldehyde generated by these pathways is chiefly metabolized to fatty acid by fatty aldehyde dehydrogenase (FALDH, alternately known as ALDH3A2), which also functions to oxidize...

    2001-01-01

    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.

    Full Text Available 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.

    Alcohol misuse remains the single most important contributing factor to road accident deaths and injuries in Australia. The results of compulsory blood alcohol tests on road casualties have shown that probationary licensed drivers have a threefold increased risk of road accident injury compared to fully licensed drivers and are additionally over-represented in alcohol-related crashes. These findings led the Victorian Road Trauma Committee to campaign for a zero blood alcohol limit for learner and probationary drivers and motorcyclists. In May 1984, zero blood alcohol legislation was enacted in Victoria. The present legislation applies to learner and first year probationary licence holders. For the first time we have evidence of a moderate reduction in alcohol-related road trauma in Victoria. Between 1977 and 1983 there has been a significant reduction in the proportion of driver casualties admitted to hospital with illegal blood alcohol concentrations and in the number of driver fatalities with blood alcohol concentrations in excess of 0.15 g%. An evaluation of the following recommended drink driver countermeasures is presented: improved driver education, increased penalties, re-education--rehabilitation programmes for convicted drink drivers, interlock devices and an increase in the legal drinking age.

    Alcoholism is a medical, social, and economic problem where treatment methods mostly include difficult and long-lasting psychotherapy and, in some cases, quite controversial pharmacological approaches. A number of medicinal plants and pure natural compounds are reported to have preventive and therapeutic effects on alcoholism and alcohol dependency, but their constituents, efficacy and mechanism of action are mostly unknown so far. Recently, kudzu [Pueraria lobata (Willd.) Ohwi], St. John's wort (Hypericum perforatum L.), danshen (Salvia miltiorrhiza Bge.), ginseng (Panax ginseng C.A. Mey.), Japanese raisin tree (Hovenia dulcis Thunb.), ibogaine (Tabernanthe iboga H. Bn.), evening primrose (Oenothera biennis L.), prickly pear fruit (Opuntia ficus indica (L.) Mill.), purple passionflower (Passiflora incarnata L.), thyme (Thymus vulgaris L.), fenugreek seed (Trigonella foenum-graecum L.), ginger (Zingiber officinale Roscoe) and many others drew the attention of researchers. Can, therefore, drugs of natural origin be helpful in the treatment of alcoholism or in decreasing alcohol consumption? PMID:22474979

    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.

    2004-05-15

    Alcohol use during pregnancy is a leading, preventable cause of birth defects and developmental disabilities in the United States, with fetal alcohol syndrome (FAS) being one of the most severe outcomes. Current survey statistics find that approximately one in eight pregnant women (500,000 per year) report alcohol use, with approximately 80,000 reporting binge drinking. While annual rates have fluctuated, trends analysis finds that there has been no significant change in rates of prenatal alcohol exposure over the past 10-year period. Development of effective programs to prevent FAS and to monitor the success of prevention efforts requires epidemiological data systems to inform these activities. This article describes alcohol use patterns among childbearing-age women and data sources that can be used in monitoring this behavior. PMID:15095466

    AIM: To investigate the relationship between genetic polymorphism of the CD14 promoter and the occurrence of alcoholic cirrhosis and alcoholic pancreatitis, and to challenge the conclusion made earlier that the patients with acute alcoholic pancreatitis and patients with alcoholic cirrhosis of liver are two different subpopulations.METHODS: Using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, we determined the polymorphism of CD14 gene and aldehyde dehydrogenase gene 2 (ALDH 2) in 335 alcoholic patients with different organ complications i.e., cirrhosis of liver (n = 100), acute pancreatitis (n = 100), esophageal cancer (n = 82) and avascular necrosis of hip joint (AVN) (n = 53)and 194 non-alcoholic controls in a Chinese group.RESULTS: The results showed that the carriage of T allele was not different among alcoholic patients with cirrhosis of liver, alcoholic patients with other complication and non-alcoholic controls. On the other hand, the carriage of the C allele was significantly more prevalent for alcoholic pancreatitis than for esophageal cancer (0.79 vs 0.60,P<0.001), alcoholic AVN (0.79 vs 0.65, P<0.025) and nonalcoholic controls (0.79 vs 0.68, P<0.025). Furthermore,when only subjects with ALDH2 1-1 genotype were examined, the C allele frequency was significantly more prevalent for alcoholic pancreatitis than for alcoholic liver cirrhosis (0.82 vs 0.69, P<0.025), esophageal cancer (0.82 vs 0.61, P<0.01), alcoholic AVN (0.82 vs 0.64,P<0.01) and non-alcoholic controls (0.82 vs 0.69, P<0.05).CONCLUSION: The C allele may be associated with some mechanism, which is important in the pathogenesis of alcoholic pancreatitis, and that alcoholic patients with acute pancreatitis and cirrhosis of liver are probably two different subpopulations.

    The high-frequency and low-amplitude dynamic mechanical response from a single poly(vinyl alcohol) chain was investigated. Modification of a commercial atomic force microscope enabled high-frequency and low-amplitude periodic deformations of polymer chains during extension to be performed. Such an...... mechanical response from poly(vinyl alcohol) does not differ from its static response. This result is not unexpected as poly(vinyl alcohol) is a highly flexible polymer with intramolecular relaxation processes taking place on a short time scale. The choice of a polymer with a fast relaxation allows its...

  7. Chain-Chain Based Routing Protocol

    Full Text Available Wireless sensor network (WSN is an emerging technology for monitoring physical world. WSNs consist of large numbers of sensor nodes operated by battery mostly in harsh environment. Thus energy conservation is a primary issue for organization of these sensor nodes. Another crucial issue is the data delivery time by sensor nodes to the sink node, especially in Military, medical fields, and security monitoring systems where minimum delay is desirable. Number of protocols has been proposed in the literature for routing. One of such protocols is the cluster based routing protocol LEACH (low energy adaptive clustering hierarchy. LEACH protocol organizes WSN into a set of clusters and a periodic voting for cluster head is performed in order to be evenly distributed among all the sensors of the WSN. This periodical cluster head voting in LEACH, however, consumes an amount of non-negligible energy and other resources. For energy conservation, PEGASIS (power efficient gathering in sensor information systems a near optimal chain-based protocol has been proposed, however, it is faced with the challenge of long delay for the transmitted data. Another routing protocol called CCM (Chain-Cluster based Mixed routing, which is mainly a hybrid of LEACH and PEGASIS is proposed, the consumed energy increases as network size increases. In this paper, we propose an efficient routing protocol called CCBRP (Chain-Chain based routing protocol, it achieves both minimum energy consumption and minimum delay. The CCBRP protocol mainly divides a WSN into a number of chains (Greedy algorithm is used to form each chain as in PEGSIS protocol and runs in two phases. In the first phase, sensor nodes in each chain transmit data to their chain leader nodes in parallel. In the second phase, all chain leader nodes form a chain (also, using Greedy algorithm and choose randomly a leader node then all chain leader nodes send their data to this chosen leader node. This chosen leader node

    Alcohol-related harm constitutes a significant factor decreasing work productivity. Of heavy alcohol users, most participate in working life. According to labour contract law, a person attending the workplace inebriated can be fired. If the employer applies a deferral to treatment practice, the drug- or alcohol-addicted person can be provided with the choice of therapy and rehabilitation instead of terminating the employment. According to the recent recommendation by the trade unions, organizations should have a program for preventing substance abuse. The employer should take care of the worker's intoxicant education and train the foremen to intervene in the situations on time. PMID:19492706

  12. Discrete Quantum Markov Chains

    CERN Document Server

    Faigle, Ulrich

    2010-01-01

    A framework for finite-dimensional quantum Markov chains on Hilbert spaces is introduced. Quantum Markov chains generalize both classical Markov chains with possibly hidden states and existing models of quantum walks on finite graphs. Quantum Markov chains are based on Markov operations that may be applied to quantum systems and include quantum measurements, for example. It is proved that quantum Markov chains are asymptotically stationary and hence possess ergodic and entropic properties. With a quantum Markov chain one may associate a quantum Markov process, which is a stochastic process in the classical sense. Generalized Markov chains allow a representation with respect to a generalized Markov source model with definite (but possibly hidden) states relative to which observables give rise to classical stochastic processes. It is demonstrated that this model allows for observables to violate Bell's inequality.

    This article addresses the problem in which a chain falls from a glass from some height. This phenomenon demonstrates a paradoxical rise of the chain over the glass. To explain this effect, an initial hypothesis and an appropriate theory are proposed for calculating the steady fall parameters of the chain. For this purpose, the modified Cayley's problem of falling chain given its rise due to the centrifugal force of upward inertia is solved. Results show that the lift caused by an increase in linear density at the part of chain where it is being bent (the upper part) is due to the convergence of the chain balls to one another. The experiments confirm the obtained estimates of the lifting chain.

    Full Text Available Introduction. Alcoholism could represent an important factor of crime and different forms of abuse of family members (physical and emotional exist in many alcohol-addict cases, as well as characteristics of immoral behaviour. Objective. The objective of our study was to determine the predominating forms in moral judgment of alcohol addicts, and to examine whether there was any statistically significant difference in moral judgment between alcohol addicted persons and non-alcoholics from general population. Methods. The sample consisted of 62 subjects, divided into a study (alcoholics and a control group (non-alcoholics from general population. The following instruments were used: social-demographic data, AUDIT, MMPI-201, cybernetic battery of IQ tests (KOG-3 and the TMR moral reasoning test. Results. Mature forms of moral judgment prevailed in both group of subjects, alcohol addicted persons and non-alcoholics. Regarding mature forms of moral judgment (driven by emotions and cognitive non-alcoholics from the general population had higher scores, but the difference was not statistically significant. Regarding socially adapted and egocentric orientation alcohol addicted persons had higher scores. However, only regarding intuitive-irrational orientation there was a statistically significant difference in the level of moral judgment (p<0.05 between alcoholics and non-alcoholics, in favour of the alcoholics. Conclusion. Moral judgment is not a category differing alcohol addicted persons from those who are not. Nevertheless, the potential destructivity of alcoholism is reflected in lower scores regarding mature orientations in moral judgment.

    Poly(aryl ether ketone)/sulfated poly(vinyl alcohol) (S-SPAEK/SPVA) composite membranes with different mass fractions of SPVA were prepared by solution casting using highly sulfonated side-chaintype sulfonated poly(aryl ether ketone) and sulfated poly(vinyl alcohol) as raw materials.Fourier transform infrared (FTIR) spectroscopy confirmed the structure of the S-SPAEK/SPVA composite membranes.Scanning electron microscope (SEM) images showed that SPVA was uniformly dispersed in an S-SPAEK polymer matrix.The uptake and swelling behavior,water retention capacity,methanol permeability,and proton conductivity of the composite membrane were investigated systematically.The performance testing of the composite membranes revealed that thermal stability and water absorption and retention capabilities were improved by introduction of SPVA.The methanol permeability of S-SPAEK/SPVA composite membranes decreased as the content of SPVA increased because the hydroxyl groups could effectively obstruct diffusion of methanol molecules.The methanol diffusion coefficients of the composite membranes decreased from 7.9 x 10-7 cm2 · s-1 for S-SPAEK/SPVA5 to 1.3 x 10-7 cm2 · s-1 for S-SPAEK/SPVA30; considerably lower than 11.5x 10-7 cm2· s-1 for the pure S-SPAEK membrane.The water absorption and retention capabilities increased as the numbers of hydrophilic groups increased by introduction of SPVA.As a result,the proton conductivity of the composite membranes increased with increasing water absorption and retention capabilities according to the Vehicle and Grotthuss mechanisms.The flexible chain segment of SPVA interacted strongly with the pendant chain of S-SPAEK,aiding hydrophilic/hydrophobic separation,and improving the proton conductivity of the composite membranes.The proton conductivity of the S-SPAEK/SPVA30 composite membrane reached 0.071 and 0.095 S· cm-1 at 25 and 80 ℃ C,respectively.These results show that S-SPAEK/SPVA composite membranes are promising for application in

      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.

    A 55-year-old man was admitted for a femur fracture; an alcohol fetor was noted on admission. The following day, the patient began to experience tremors and nervousness. Intravenous haloperidol was administered. Shortly afterwards, the patient experienced two generalized seizures and then began to experience delirium and uncontrollable agitation. The patient was diagnosed with alcohol withdrawal syndrome; high doses of intravenous midazolam were prescribed and infused. A few hours later, the patient presented signs of respiratory depression, requiring a transfer to the intensive care unit. After a review of the medical history, it was determined that the patient had been admitted on 3 previous occasions due to alcohol withdrawal and had progressed to delirium tremens after experiencing seizures. Can the risk of alcohol withdrawal syndrome and the need for prophylactic treatment be assessed on admission? Were appropriate monitoring and treatment measures employed?

    2015-01-01

    With the exception of cardiovascular diseases, no other medical condition causes more serious dysfunction or premature deaths than alcohol-related problems. Research results indicate that alcohol dependent individuals present an exceptionally poor level of quality of life. This is an outcome that highlights the necessity of planning and implementing preventive interventions on biological, psychological or social level, to be provided to individuals who make alcohol abuse, as well as to their families. Preventive interventions can be considered on three levels of prevention: (a) primary prevention, which is focused on the protection of healthy individuals from alcohol abuse and dependence, and may be provided on a universal, selective or indicated level, (b) secondary prevention, which aims at the prevention of deterioration regarding alcoholic dependence and relapse, in the cases of individuals already diagnosed with the condition and (c) tertiary prevention, which is focused at minimizing deterioration of functioning in chronically sufferers from alcoholic dependence. The term "quaternary prevention" can be used for the prevention of relapse. As for primary prevention, interventions focus on assessing the risk of falling into problematic use, enhancing protective factors and providing information and health education in general. These interventions can be delivered in schools or in places of work and recreation for young people. In this context, various programs have been applied in different countries, including Greece with positive results (Preventure, Alcolocks, LST, SFP, Alcohol Ignition Interlock Device). Secondary prevention includes counseling and structured help with the delivery of programs in schools and in high risk groups for alcohol dependence (SAP, LST). These programs aim at the development of alcohol refusal skills and behaviors, the adoption of models of behaviors resisting alcohol use, as well as reinforcement of general social skills. In the

  15. Crater chains on Mercury

    Science.gov (United States)

    Shevchenko, V.; Skobeleva, T.

    After discovery of disruption comet Shoemaker-Levy 9 into fragment train before it's collision with Jupiter there was proposed that linear crater chains on the large satellites of Jupiter and on the Moon are impact scars of past tidally disrupted comets.It's known that radar images have revealed the possible presence of water ice deposits in polar regions of Mercury. Impacts by a few large comets seem to provide the best explanation for both the amount and cleanliness of the ice deposits on Mercury because they have a larger volatile content that others external sources, for example, asteroid. A number of crater chains on the surface of Mercury are most likely the impact tracks of "fragment trains" of comets tidally disrupted by Sun or by Mercury and are not secondary craters. Mariner 10 image set (the three Mariner 10 flybys in 1974-1975) was used to recognize the crater chains these did not associate with secondary crater ejecta from observed impact structures. As example, it can be shown such crater chain located near crater Imhotep and crater Ibsen (The Kuiper Quadrangle of Mercury). Resolution of the Mariner 10 image is about 0.54 km/pixel. The crater chain is about 50 km long. It was found a similar crater chain inside large crater Sophocles (The Tolstoj Quadrangle of Mercury). The image resolution is about 1.46 km/pixel. The chain about 50 km long is located in northen part of the crater. Image resolution limits possibility to examine the form of craters strongly. It seems the craters in chains have roughly flat floor and smooth form. Most chain craters are approximately circular. It was examined many images from the Mariner 10 set and there were identified a total 15 crater chains and were unable to link any of these directly to any specific large crater associated with ejecta deposits. Chain craters are remarkably aligned. All distinguished crater chains are superposed on preexisting formations. A total of 127 craters were identified in the 15 recognized

    Guo, Daoyi; Pan, Hong; Li, Xun

    2015-09-01

    Microbial production of biodiesel from renewable feedstock has attracted intensive attention. Biodiesel is known to be produced from short-chain alcohols and fatty acyl-CoAs through the expression of wax ester synthase/fatty acyl-CoA: diacylglycerol acyltransferase that catalyzes the esterification of short-chain alcohols and fatty acyl-CoAs. Here, we engineered Escherichia coli to produce various fatty alcohol acetate esters, which depend on the expression of Saccharomyces cerevisiae alcohol acetyltransferase ATF1 that catalyzes the esterification of fatty alcohols and acetyl-CoA. The fatty acid biosynthetic pathways generate fatty acyl-ACPs, fatty acyl-CoAs, or fatty acids, which can be converted to fatty alcohols by fatty acyl-CoA reductase, fatty acyl-ACP reductase, or carboxylic acid reductase, respectively. This study showed the biosynthesis of biodiesel from three fatty acid biosynthetic pathway intermediates. PMID:26205521

    A case-control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to individuals in areas of high alcohol outlet availability was less than the gun suicide risk they incurred from acute alcohol consumption, especially to excess. This corroborates prior work but also uncovers new information about the relationships between acute alcohol consumption, alcohol outlets, and gun suicide. Study limitations and implications are discussed. PMID:21929327

    2011-12-01

    Alcohol-specific communication, a direct conversation between an adult and an adolescent regarding alcohol use, contains messages about alcohol relayed from the adult to the child. The current study examined the construct of alcohol-specific communication and the effect of messages on adolescent alcohol use and alcohol-related consequences. Parent-adolescent dyads were assessed biannually for 3 years (grades 9-11 at wave 6) to examine these relations in a large longitudinal study of adolescents initially in grades 6 through 8. An exploratory factor analysis identified two factors among alcohol-specific communication items, permissive messages and negative alcohol messages. Results showed previous level of adolescent alcohol use moderated the relation between permissive messages and alcohol use outcomes. Plotting of these interactions showed greater alcohol use and consequences with increasing permissive messages in adolescents with higher versus lower levels of previous alcohol use. Results suggest that parental messages regarding alcohol use may impact adolescent alcohol use beyond the effect of general parenting style and parental alcohol use. PMID:21667141

  11. Crystal Structure of Alcohol Oxidase from Pichia pastoris.

    Directory of Open Access Journals (Sweden)

    Christian Koch

    Full Text Available FAD-dependent alcohol oxidases (AOX are key enzymes of methylotrophic organisms that can utilize lower primary alcohols as sole source of carbon and energy. Here we report the crystal structure analysis of the methanol oxidase AOX1 from Pichia pastoris. The crystallographic phase problem was solved by means of Molecular Replacement in combination with initial structure rebuilding using Rosetta model completion and relaxation against an averaged electron density map. The subunit arrangement of the homo-octameric AOX1 differs from that of octameric vanillyl alcohol oxidase and other dimeric or tetrameric alcohol oxidases, due to the insertion of two large protruding loop regions and an additional C-terminal extension in AOX1. In comparison to other alcohol oxidases, the active site cavity of AOX1 is significantly reduced in size, which could explain the observed preference for methanol as substrate. All AOX1 subunits of the structure reported here harbor a modified flavin adenine dinucleotide, which contains an arabityl chain instead of a ribityl chain attached to the isoalloxazine ring.

    In this paper chain cacti are considered. First, for two specific classes of chain cacti (orto-chains and meta-chains of cycles with h vertices) the recurrence relation for independence polynomial is derived. That recurrence relation is then used in deriving explicit expressions for independence number and number of maximum independent sets for such chains. Also, the recurrence relation for total number of independent sets for such graphs is derived. Finaly, the proof is provided that orto-chains and meta-chains are the only extremal chain cacti with respect to total number of independent sets (orto-chains minimal and meta-chains maximal).

    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

    The interaction by hydrogen bond formation of some primary alcohols (1-heptanol, 1-octanol and 1-decanol) with esters (methyl methacrylate, ethyl methacrylate and butyl methacrylate) was investigated in non-polar solvents viz., n-heptane,CCh and benzene by means of FTIR spectroscopy. Formation constants and free energy changes of complex formation were determined. The dependence of the equilibrium constants and free energy changes of complex formation on the alkyl chain length of both the alcohols and esters are discussed. The solvent effect on the hydrogen bond formation is discussed in terms of specific interaction between the solute and solvent.

  19. The economics of alcohol abuse and alcohol-control policies.

    Science.gov (United States)

    Cook, Philip J; Moore, Michael J

    2002-01-01

    Economic research has contributed to the evaluation of alcohol policy through empirical analysis of the effects of alcohol-control measures on alcohol consumption and its consequences. It has also provided an accounting framework for defining and comparing costs and benefits of alcohol consumption and related policy interventions, including excise taxes. The most important finding from the economics literature is that consumers tend to drink less ethanol, and have fewer alcohol-related problems, when alcoholic beverage prices are increased or alcohol availability is restricted. That set of findings is relevant for policy purposes because alcohol abuse imposes large "external" costs on others. Important challenges remain, including developing a better understanding of the effects of drinking on labor-market productivity. PMID:11900152

    To develop pathways for advanced biological upgrading of sugars to hydrocarbons, we are seeking biological approaches to produce high carbon efficiency intermediates amenable to separations and catalytic upgrading to hydrocarbon fuels. In this study, we successfully demonstrated fatty alcohol production by oleaginous yeasts Yarrowia lipolytica and Lipomyces starkeyi by expressing a bacteria-derived fatty acyl-CoA reductase (FAR). Moreover, we find higher extracellular distribution of fatty alcohols produced by FAR-expressing L. starkeyi strain as compared to Y. lipolytica strain, which would benefit the downstream product recovery process. In both oleaginous yeasts, long chain length saturated fatty alcohols were predominant, accounting for more than 85% of the total fatty alcohols produced. To the best of our knowledge, this is the first report of fatty alcohol production in L. starkeyi. Taken together, our work demonstrates that in addition to Y. lipolytica, L. starkeyi can also serve as a platform organism for production of fatty acid-derived biofuels and bioproducts via metabolic engineering. We believe strain and process development both will significantly contribute to our goal of producing scalable and cost-effective fatty alcohols from renewable biomass.

  1. Understanding the supply chain

    Directory of Open Access Journals (Sweden)

    Aćimović Slobodan

    2006-01-01

    Full Text Available Supply chain management represents new business philosophy and includes strategically positioned and much wider scope of activity in comparison with its "older brother" - management of logistics. Philosophy of the concept of supply chain is directed to more coordination of key business functions of every link in distribution chain in the process of organization of the flow of both goods and information, while logistic managing instruments are focused on internal optimum of flows of goods and information within one company. Applying the concept of integrated supply chain among several companies makes the importance of operative logistics activity even greater on the level of one company, thus advancing processes of optimum and coordination within and between different companies and confirms the importance of logistics performances for the company’s profitability. Besides the fact that the borders between companies are being deleted, this concept of supply chain in one distribution channel influences increasing of importance of functional, i.e. traditional business managing approaches but instead it points out the importance of process managing approaches. Although the author is aware that "there is nothing harder, more dangerous and with uncertain success, but to find a way for introducing some novelties (Machiavelli, it would be even his additional stimulation for trying to bring closer the concept and goals of supply chain implementation that are identified in key, relevant, modern, theoretical and consulting approaches in order to achieve better understanding of the subject and faster implementation of the concept of supply chain management by domestic companies.

  2. SUMO chains: polymeric signals.

    Science.gov (United States)

    Vertegaal, Alfred C O

    2010-02-01

    Ubiquitin and ubiquitin-like proteins are conjugated to a wide variety of target proteins that play roles in all biological processes. Target proteins are conjugated to ubiquitin monomers or to ubiquitin polymers that form via all seven internal lysine residues of ubiquitin. The fate of these target proteins is controlled in a chain architecture-dependent manner. SUMO (small ubiquitin-related modifier) shares the ability of ubiquitin to form chains via internal SUMOylation sites. Interestingly, a SUMO-binding site in Ubc9 is important for SUMO chain synthesis. Similar to ubiquitin-polymer cleavage by USPs (ubiquitin-specific proteases), SUMO chain formation is reversible. SUMO polymers are cleaved by the SUMO proteases SENP6 [SUMO/sentrin/SMT3 (suppressor of mif two 3)-specific peptidase 6], SENP7 and Ulp2 (ubiquitin-like protease 2). SUMO chain-binding proteins including ZIP1, SLX5/8 (synthetic lethal of unknown function 5/8), RNF4 (RING finger protein 4) and CENP-E (centromere-associated protein E) have been identified that interact non-covalently with SUMO chains, thereby regulating target proteins that are conjugated to SUMO multimers. SUMO chains play roles in replication, in the turnover of SUMO targets by the proteasome and during mitosis and meiosis. Thus signalling via polymers is an exciting feature of the SUMO family.

    The association between alcohols and N,N-dimethylacetamide in carbon tetrachloride was investigated using FFIR spectroscopy at 298 K. The formation constants for 1:1 and 1:2 complexes were calculated using the method of Whetsel and Kagarise. The observed 1:1 complex values were also verified using the method of Nash. The rate of change in C =O bond moment on complexing with alcohols increased with increasing acidity of alcohols. The formation constant and values of free energy change increased with the increase in carbon chain length of alcohols,which suggested that the degree of complex formation varied with the length of the carbon chain of alcohols.

    Full Text Available Background: Supply chain risk management increasingly gains prominence in many international industries. In order to strengthen supply chain structures, processes, and networks, adequate potentials for risk management need to be built (focus on effective logistics and to be utilized (focus on efficient logistics. Natural-based disasters, such as the case of Fukushima, illustrate how crucial risk management is. Method: By aligning a theoretical-conceptual framework with empirical-inductive findings, it may be hypothesized that logistical systems do have a positive effect on supply chain risk management activities.  Result/conclusion:  Flexibility and capacity, as well as redundancy and standardization, are often viewed as being conflictionary. It shows, however, that in the light of supply chain risk management, those factors may yield a common benefit if proper logistics systems are applied.

  13. Alcohol content variation in the assessment of alcohol consumption.

    Science.gov (United States)

    Martin, C S; Nirenberg, T D

    1991-01-01

    Most investigators have not adequately accounted for the alcohol content of different beverages when assessing alcohol consumption. Considerable research has assessed consumption in terms of the number of standard drinks. A problem with standard drink measures is that different distilled spirits, wines, and malt beverages vary considerably in alcohol content. State-to-state and brand-to-brand variations in the strength of different malt beverage brands are provided, as malt beverage alcohol contents are not contained on labels due to federal and state regulations. Ignoring alcohol content variation when estimating consumption can produce a large amount of error. Alcohol consumption should be assessed in terms of the number, size, and alcohol content of beverages. PMID:1801580

    2013-09-01

    The conversion of branched-chain amino acids to branched-chain acids or alcohols is an important aspect of flavor in the food industry and is dependent on the Ehrlich pathway found in certain lactic acid bacteria. A key enzyme in the pathway, the 2-keto acid decarboxylase (KDC), is also of interest in biotechnology applications to produce small branched-chain alcohols that might serve as improved biofuels or other commodity feedstocks. This enzyme has been extensively studied in the model bacterium Lactococcus lactis, but is also found in other bacteria and higher organisms. In this report, distinct homologs of the L. lactis KDC originally annotated as pyruvate decarboxylases from Psychrobacter cryohalolentis K5 and P. arcticus 273-4 were cloned and characterized, confirming a related activity toward specific branched-chain 2-keto acids derived from branched-chain amino acids. Further, KDC activity was confirmed in intact cells and cell-free extracts of P. cryohalolentis K5 grown on both rich and defined media, indicating that the Ehrlich pathway may also be utilized in some psychrotrophs and psychrophiles. A comparison of the similarities and differences in the P. cryohalolentis K5 and P. arcticus 273-4 KDC activities to other bacterial KDCs is presented. PMID:23826991

    Companies are now progressively looking beyond themselves to come up with ways to improve revenue and profit margins. This has resulted in a heightened focus on the efficiency of the supply chains. Inefficient supply chains are being perceived as cavities that can deprive the firm from its cash flows when inventory is not required and sales revenue when product is not available at the point of sales. This has stimulated development of business models that intend to leverage and enhance the su...

  16. Variance bounding Markov chains

    OpenAIRE

    Roberts, Gareth O.; Jeffrey S. Rosenthal

    2008-01-01

    We introduce a new property of Markov chains, called variance bounding. We prove that, for reversible chains at least, variance bounding is weaker than, but closely related to, geometric ergodicity. Furthermore, variance bounding is equivalent to the existence of usual central limit theorems for all L2 functionals. Also, variance bounding (unlike geometric ergodicity) is preserved under the Peskun order. We close with some applications to Metropolis–Hastings algorithms.

    Background: Supply chain risk management increasingly gains prominence in many international industries. In order to strengthen supply chain structures, processes, and networks, adequate potentials for risk management need to be built (focus on effective logistics) and to be utilized (focus on efficient logistics). Natural-based disasters, such as the case of Fukushima, illustrate how crucial risk management is. Method: By aligning a theoretical-conceptual framework with empirical-induct...

    Highly efficient esterification of alcohols with acetic acid by using a Bransted acidic ionic liquid, i.e., 1-methyl-2-pyrrolidonium hydrogen sulfate ([Hnmp]HSo4), as catalyst has been realized. The turnover numbers (TON) were able to reach up to 11000 and turnover frequency (TOF) was 846. The catalytic system is suitable for the esterification of long chain aliphatic alcohols, benzyl alcohol and cyclohexanol with good yields of esters. The procedure of separating the product and catalyst is simple, and the catalyst could be reused. [Hnmp]HSO4 had much weaker corrosiveness than H2SO4. The corrosive rate of H2SO4 was 400 times more than that of [Hnmp]HSO4 to stainless steel.

    The retention indices of aliphatic alcohols of carbon number up to C{sub g}, and of their benzoyl derivatives up to C{sub 7}, were determined in columns packed with Chromo sorb G (AW-DMCS-HP) coated previously with 5% methyl, and methyl phenyl polysiloxanes with increasing polarity (SE-30, 0V-3, 0V-7, 0V-11, 0V-17 and OV-25). Correlations between retention indices and chain length for 1-alcohols, 2-alcohols, 3-alcohols, 1 , on -3-alcohols, 2-methyl-1-alcohols and for their corresponding benzoyl derivatives were calculated at 100, 120 and 140 degree centigree. In alcohols, a -CH{sub 2}- group increases I approximately 100 units, and in their benzoyl derivatives from 80 to 100 units. Dispersion indices {delta}l , and positional and structural increments {delta}I, were evaluated for -OH and benzoyl groups in terms of phase polarity and chain length. Effects of chain length, chain branching and double bond location on retention parameters were also studied. (Author) 23 refs.

    1990-04-01

    Body composition was evaluated in healthy detoxified alcoholics (aged 20-39) and lifestyle controls, with the expectation that prolonged, excessive consumption of alcohol may bring about nutritional or toxicologic alterations in the relationship between body fat and lean body mass. Body fat was assessed by measurements of skin-fold thickness and by means of bioelectric impedance methodology. No noteworthy differences were observed between alcoholics and controls with regard to the relationship between lean body mass and body fat or in the relationship between extracellular and intracellular water. It would appear that 15-20 years of heavy alcohol consumption does not necessarily alter body composition in healthy, young alcoholics. PMID:2190482

  4. Structural and phase transition changes of sodium dodecyl sulfate micellar solution in alcohols probed by small-angle neutron scattering (SANS)

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) measurements on 0.3M sodium dodecyl sulfate (SDS) micellar solutions have been performed in the presence of n-alcohols, from ethanol to decanol at different alcohol concentrations, 2–10 wt%. The ellipsoid micellar structure which occurred in the 0.3M SDS in aqueous solution with the size range of 30–50 Å has different behavior at various hydrocarbon chain length and concentration of alcohols. At low concentration and short chain-length of alcohols, such as ethanol, propanol, and butanol, the size of micelles reduced and had a spherical-like structure. The opposite effect occurred as medium to long chain alcohols, such as hexanol, octanol and decanol was added into the 0.3M SDS micellar solutions. The micelles structure changed to be more elongated in major axis and then crossed the critical phase transition from micellar solution into liquid crystal phase as lamellar structure emerged by further addition of alcohols. The inter-lamellar distances were also depending on the hydrocarbon chain length and concentration of alcohols. In the meantime, the persistent micellar structures occurred in addition of medium chain of n-alcohol, pentanol at all concentrations

    Ultra-fine magnetic particles are difficult to be dispersed in low boiling point solvents such as alcohol (C 1-C 4) and acetone. In this paper, we report the preparation methods of several alcohol and acetone-based magnetic fluids. The stability of magnetic fluid depended on the HLB (hydrophile-lipophile balance) of the solvent and alkyl chain lengths of organic layers. The fluid was most stable only when the HLB value of surfactant and the solvents are similar.

    Uncoupling proteins (UCPs) are anion channels that can decouple the mitochondrial respiratory chain. "Mild uncoupling" of internal respiration reduces free radical production and oxidative cell stress. Chronic alcohol consumption is a potent inducer of oxidative stress in multiple tissues and regulates UCP-2 and -4 expression in the brain. To analyse the impact of chronic alcohol intake on UCP-2 expression in tissues with high endogenous UCP-2 contents, male Wistar rats (n=34) were treated wi...

  9. Genetic studies in alcohol research

    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.

    Alcohol-related pathologies lead to most serious expressions, both at clinical and social level. The diffused social acceptance of consumption and abuse behavior and the lack of alcohol education for professionals (physicians, psychologists, social workers etc.) make difficult to put in the right frame this issue. Just a multidimensional approach can make the problem understandable. The history of alcohol consumption during the time gives us an exhaustive picture of the negative consequences of alcohol consumption. Alcohol consumption during pregnancy is a problem still underestimated and represents a serious risk for the health of the newborns: children alcohol-exposed in uterus are at risk to develop many pathologies and even the fetal-alcohol syndrome (FAS) that leads to facial anomalies, growth deficiencies and neurological damages. Therefore interventions coping with this kind of issues are needed in order to enhance people's health. PMID:15269446

    Sum-frequency vibrational spectroscopy and second-harmonic generation have been used to measure the orientational distributions of the polymer chains and adsorbed 8CB liquid crystal molecules on a rubbed polyvinyl alcohol surface. Results show that the polymer chains at the surface appear to be well aligned by rubbing, and the adsorbed liquid crystal molecules are aligned, in turn, by the surface polymer chains. Strong correlation exists between the orientational distributions of the polymer chains and the liquid crystal molecules, indicating that the surface-induced bulk alignment of a liquid crystal film by rubbed polymer surfaces is via an orientational epitaxylike mechanism.

    Full Text Available The IGPC Engineering Department designed basic projects for dry alcohol production plant, using technology developed in the IGPC laboratories. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects a production plant with a capacity of 40 m3/y was manufactured, at "Zorka Pharma", Šabac in 1995-1996. The product meets all quality demands, as well as environmental regulations. The dry alcohol production process is fully automatized. There is no waste in the process, neither gaseous, nor liquid. The chosen process provides safe operation according to temperature regime and resistance in the pipes, air purification columns and filters. Working at increased pressure is suitable for evaporation and condensation at increased temperatures. The production process can be controlled manually, which is necessary during start-up, and repairs.

    Hidden Markov chains have been shown to be inadequate for data modeling under some complex conditions. In this work, we address the problem of statistical modeling of phenomena involving two heterogeneous system states. Such phenomena may arise in biology or communications, among other fields. Namely, we consider that a sequence of meaningful words is to be searched within a whole observation that also contains arbitrary one-by-one symbols. Moreover, a word may be interrupted at some site to be carried on later. Applying plain hidden Markov chains to such data, while ignoring their specificity, yields unsatisfactory results. The Phasic triplet Markov chain, proposed in this paper, overcomes this difficulty by means of an auxiliary underlying process in accordance with the triplet Markov chains theory. Related Bayesian restoration techniques and parameters estimation procedures according to the new model are then described. Finally, to assess the performance of the proposed model against the conventional hidden Markov chain model, experiments are conducted on synthetic and real data. PMID:26353069

    In this method for extraction of alcohol from fermented material, insoluble organic matter is first removed before the ferment enters the distillation column and tried spent grains then recovered by drying under pressure. Excess steam from the drying stage is used to heat the distillation column. In addition, excess water vapour produced as a result of further heating by head vapour from the first distillation column, is drawn off from the evaporation step, condensed and fed into the distillation columns and evaporation step.

    First, epidemiological data and socioeconomic consequences of alcohol addiction are summarized. Research findings, in particular in intervention and evaluation, from 2009-2011 in the field of alcohol addiction treatment are then discussed concerning their relevance for rehabilitation practice. The search was based on PubMed and PSYNDEX. The interventions most frequently evaluated and found most effective in alcohol addiction treatment are cognitive-behavioural interventions. Further topics dealt with are: pharmacological relapse prevention; technologically based therapies (e. g. e-therapy); systemic interventions; 12-steps; effectiveness of addiction treatment as confirmed in large-scale catamnestic studies; treatment of addiction and comorbidity; various subgroups (like elderly people and women); as well as other new and interesting developments such as rehab case management, dovetailing of medical and vocational interventions, stepped-care interventions, rehab management category groups as well as a new focus on individual treatment experiences and the pre-eminence of the therapeutic relationship. Finally, priority areas of future research are described. PMID:21976262

    According to the nomenclature of Vallee and Bazzone [1983] for mammalian alcohol dehydrogenase (ADH) isozymes, baboon ADHs comprise three major classes of activity, which were distinguished according to the following properties: Class I ADHs. These isozymes exhibited low-Km characteristics with ethanol as substrate, high isoelectric points (8.5-9.3), and sensitivity to 5 mM 4-methyl pyrazole inhibition, and were the major liver (ADH-2) and kidney (ADH-1) isozymes in the baboon. Class II ADHs. These isozymes showed high-Km values for ethanol, neutral isoelectric points (7.7 for the liver ADH-4 [pi-ADH] and 7.2 for the major stomach ADH [ADH-3], respectively), and were insensitive to inhibition with 5 mM 4-methyl pyrazole. Class III ADH. This enzyme was characterized by its inactivity with ethanol as substrate (up to 0.5 M), insensitivity to 4-methyl pyrazole inhibition, preference for medium-chain-length alcohols as substrate (trans-2-hexen-1-ol was routinely used in this study), and an isoelectric point (6.5) similar to that of the human liver chi-ADH (pI 6.4). Major activity variation of the liver pi-ADH (ADH-4) isozyme was observed among the 114 liver samples examined, with 34 percent exhibiting a null (or low-activity) phenotype. An electrophoretic variant phenotype for the major class II stomach isozyme (ADH-3) was also found in the population studied. The baboon was used as a model for studying alcohol-induced changes in liver ADH phenotype following chronic alcohol consumption. Prepuberal male baboons were pair-fed nutritionally adequate liquid diets containing ethanol (50 percent of calories) or isocaloric carbohydrates, and liver ADH isozyme patterns from biopsy samples were monitored for 20 weeks. Dramatic decreases in class II liver ADH activity (ADH-4, or pi-ADH) were observed within 4 weeks after the start of alcohol feeding, and a shift in liver class I isozymes was found during the later stages of alcohol consumption. These changes during chronic

    Previously, it was shown that the tetrameric potassium channel KcsA when present in a lipid bilayer can be dissociated by trifluoroethanol [van den Brink-van der Laan, E., et al. (2004) Biochemistry 43, 4240-4250]. Here, we demonstrate that this is a general property of small alcohols. We found that small alcohols dissociate the KcsA tetramer, at a concentration that depends on their membrane affinity. Importantly, the efficiency of the alcohol-induced tetramer dissociation was found to correlate with the efficiency of both alcohol-induced bilayer leakage and acyl chain disordering. Our data suggest that the ability of small alcohols to induce KcsA tetramer dissociation and to function as anesthetics depends on their effect on the membrane lateral pressure. PMID:15147177

    Amination of non-activated aliphatic fatty alcohols to the corresponding primary amines was achieved through a five-enzyme cascade reaction by coupling a long-chain alcohol oxidase from Aspergillus fumigatus (LCAO_Af) with a ω-transaminase from Chromobacterium violaceum (ω-TA_Cv). The alcohol was oxidized at the expense of molecular oxygen to yield the corresponding aldehyde, which was subsequently aminated by the PLP-dependent ω-TA to yield the final primary amine product. The overall cascade was optimized with respect to pH, O2 pressure, substrate concentration, decomposition of H2O2 (derived from alcohol oxidation), NADH regeneration, and biocatalyst ratio. The substrate scope of this concept was investigated under optimized conditions by using terminally functionalized C4–C11 fatty primary alcohols bearing halogen, alkyne, amino, hydroxy, thiol, and nitrile groups.

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.

Also, new experiments were conducted with diluted alcohol solutions to n-octanol, expanding the experimental data from C1 up to C8. The proposed empirical correlations include, beside the superficial gas velocity, the alcohol chain length as the only factor to characterize the liquid phase. The suggested correlations have shown good agreement between the calculated and the experimental data.

    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.

    The follow-up study of alcoholic psychoses in male patients admitted to a clinical department of a psychiatric hospital in 2005-2007 was carried out. Patients with alcoholic psychoses made up from 15 to 30% of all patients. The number of psychosis had seasonal variations with the elevations in spring and autumn, peaks in January, lune and October. Alcoholic delirium morbidity made up from 69 to 82% of the total number of alcoholic psychoses, alcoholic hallucinosis varied from 14 to 27%. Other forms were presented by single cases. In alcoholic delirium hallucinations had brighter, sated character. The most specific were visual hallucinations in the form of zoohallucinations, hallucinations of an oral cavity ("sensation of threads, hair etc"). The most often observable characters were "extraneous people, animal, demons". In alcoholic hallucinosis, verbal contrast hallucinations, making comment hallucinations, visual illusions were most frequent. The family history of mental disorders and alcoholism was noted in 30% of patients with alcoholic psychosis. The probability of occurrence of alcoholic psychoses depended on the quality of consumed drinks. The presence of a cranial-brain injury in the anamnesis considerably aggravated the disease forecast and increased the risk of seizure syndrome. PMID:22611692

    Full Text Available In recent years, there are several methods introduced for the improvement of operational performances. Total quality management and supply chain management are two methods recommended for this purpose. These two approaches have been studied in most researches separately, while they have objectives in common, and this makes them a strategic means, which can be used, simultaneously. Total quality management and supply chain management play significant roles to increase the organizational competitiveness power. Moreover, they have only one purpose that is customer satisfaction, and they are different only on their approaches to reach their objectives. In this research, we aim to study both approaches of quality management and supply chain, their positive increasing effects that may be generated after their integration. For this purpose, the concept and definitions of each approach is studied, independently, their similarities and differences are recognized, and finally, the advantages of their integration are introduced.

    We consider finite Markov chains where there are uncertainties in some of the transition probabilities. These uncertainties are modeled by fuzzy numbers. Using a restricted fuzzy matrix multiplication we investigate the properties of regular, and absorbing, fuzzy Markov chains and show that the basic properties of these classical Markov chains generalize to fuzzy Markov chains.

  15. Mechanism of Conformational Transition of Silk Fibroin in Alcohol-water Mixtures

    2011-01-01

    Circular dichroism, intrinsic fluorescence of protein and exogenous fluorescence probe of 8-anilino-l-naphtha-lenesulfonic acid hemimagnesium salt (ANS) was used to investigate the mechanism of conformational change of silk fibroin (SF) in aqueous alcohol including methanol and ethanol. The conformational transition of SF from ran-dom coil to β-sheet was found to be of a close relationship with the microstructure of the solvent. The alcohol-water mixture at low concentration had little effect on the solvation of the peptide unit, as the inherent water structure was conserved. At high alcohol concentration, the transition from the tetrahedral-like water structure to the chain-like alcohol structure in the mixtures induced a β-sheet conformation of SF, as a result of the formation of intramolecu-lar hydrogen bond between the peptide units in order to eliminate the thermodynamic unfavorite from the contact to the solvent molecules. Meanwhile, the aggregating of hydrophobic side chains was decreased by the alcohol via the destruction of hydrogen bond network of water by alcohol and the binding of alcohol to hydrophobic group.

    2014-01-01

    Alcohol consumption is one of the leading causes of liver diseases and liver-related death worldwide. The gut is a habitat for billions of microorganisms which promotes metabolism and digestion in their symbiotic relationship with the host. Alterations of gut microbiome by alcohol consumption are referred to bacterial overgrowth, release of bacteria-derived products, and/or changed microbiota equilibrium. Alcohol consumption also perturbs the function of gastrointestinal mucosa and elicits a pathophysiological condition. These adverse effects caused by alcohol may ultimately result in a broad change of gastrointestinal luminal metabolites such as bile acids, short chain fatty acids, and branched chain amino acids. Gut microbiota alterations, metabolic changes produced in a dysbiotic intestinal environment, and the host factors are all critical contributors to the development and progression of alcoholic liver disease. This review summarizes recent findings of how alcohol-induced alterations of gut microbiota and metabolome, and discusses the mecha-nistic link between gastrointestinal dyshomeostasis and alcoholic liver injury.

    2005-01-01

    Phenylsulfonic acid functionalized mesoporous silica was synthesized by condensation of tetraethylorthosilicate with phenyltrimethoxysilane, and then sulfonation using 30% fuming sulfuric acid. The material was characterized using FT-IR, DSC, XPS, TEM and N2 adsorption/desorption measurements. DSC revealed that sulfonic acid group of the catalyst was decomposed at 354.8℃, indicating that the catalyst exhibited high thermal stability. XPS showed that there existed three kinds of different silicon species on surface of the catalyst. The catalytic performance of the catalyst was evaluated using transetherification of alcohols with dimethoxymethane. It was found that among primary alcohols, the selectivities of the two long-chain alcohols for n-dedocanol and n-tetradecyl alcohol were higher than 97.0% at the conversions of 43.6% and 65.3%, respectively, while the selectivities of the short-chain alcohols except for n-hexanol were less than 90.0% at the conversions of over 80.0%. Due to steric bartier, the secondary alcohols such as /so-butanol and cyclohexanol afforded conversions of 79.4% and 60.5%, and the selectivities of the two alcohols were more than 90.0%. The sequence in conversion of the substituted phenols isas follows: p-nitrophenol>p-fluorophenol≥p-bromophenol>p-cresol>m-cresol.

  20. Alcohol abuse and related disorders treatment of alcohol dependence

    2014-01-01

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

    Hepatocellular carcinoma shows a rising incidence worldwide, and the largest burden of disease in Western countries derives from patients with alcoholic liver disease (ALD) and cirrhosis, the latter being the premier premalignant factor for HCC. The present chapter addresses key issues including the epidemiology of alcohol-associated HCC, and its link to other coexisting non-alcoholic liver diseases, and additional host and environmental risk factors including the underlying genetics. Also discussed are molecular mechanisms of alcohol-associated liver cancer evolution involving the mediators of alcohol toxicity and carcinogenicity, acetaldehyde and reactive oxygen species, as well as the recently described mutagenic adducts which these mediators form with DNA. Specifically, interference of alcohol with retinoids and cofactors of transmethylation processes are outlined. Information presented in this chapter illustrates that the development of HCC in the context of ALD is multifaceted and suggests several molecular targets for prevention and markers for the screening of risk groups.

    de la Monte, Suzanne M; Kril, Jillian J

    2014-01-01

    Alcohol-related diseases of the nervous system are caused by excessive exposures to alcohol, with or without co-existing nutritional or vitamin deficiencies. Toxic and metabolic effects of alcohol (ethanol) vary with brain region, age/developmental stage, dose, and duration of exposures. In the mature brain, heavy chronic or binge alcohol exposures can cause severe debilitating diseases of the central and peripheral nervous systems, and skeletal muscle. Most commonly, long-standing heavy alcohol abuse leads to disproportionate loss of cerebral white matter and impairments in executive function. The cerebellum (especially the vermis), cortical-limbic circuits, skeletal muscle, and peripheral nerves are also important targets of chronic alcohol-related metabolic injury and degeneration. Although all cell types within the nervous system are vulnerable to the toxic, metabolic, and degenerative effects of alcohol, astrocytes, oligodendrocytes, and synaptic terminals are major targets, accounting for the white matter atrophy, neural inflammation and toxicity, and impairments in synaptogenesis. Besides chronic degenerative neuropathology, alcoholics are predisposed to develop severe potentially life-threatening acute or subacute symmetrical hemorrhagic injury in the diencephalon and brainstem due to thiamine deficiency, which exerts toxic/metabolic effects on glia, myelin, and the microvasculature. Alcohol also has devastating neurotoxic and teratogenic effects on the developing brain in association with fetal alcohol spectrum disorder/fetal alcohol syndrome. Alcohol impairs function of neurons and glia, disrupting a broad array of functions including neuronal survival, cell migration, and glial cell (astrocytes and oligodendrocytes) differentiation. Further progress is needed to better understand the pathophysiology of this exposure-related constellation of nervous system diseases and better correlate the underlying pathology with in vivo imaging and biochemical lesions

    Full Text Available Background: Today it is virtually impossible to operate alone on the international level in the logistics business. This promotes the establishment and development of new integrated business entities - logistic operators. However, such cooperation within a supply chain creates also many problems related to the supply chain reliability as well as the optimization of the supplies planning. The aim of this paper was to develop and formulate the mathematical model and algorithms to find the optimum plan of supplies by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Methods: The mathematical model and algorithms to find the optimum plan of supplies were developed and formulated by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Results and conclusions: The problem of ensuring failure-free performance of goods supply channel analyzed in the paper is characteristic of distributed network systems that make active use of business process outsourcing technologies. The complex planning problem occurring in such systems that requires taking into account the consumer's requirements for failure-free performance in terms of supply volumes and correctness can be reduced to a relatively simple linear programming problem through logical analysis of the structures. The sequence of the operations, which should be taken into account during the process of the supply planning with the supplier's functional reliability, was presented.

    The Exploration Supply Chain Simulation project was chartered by the NASA Exploration Systems Mission Directorate to develop a software tool, with proper data, to quantitatively analyze supply chains for future program planning. This tool is a discrete-event simulation that uses the basic supply chain concepts of planning, sourcing, making, delivering, and returning. This supply chain perspective is combined with other discrete or continuous simulation factors. Discrete resource events (such as launch or delivery reviews) are represented as organizational functional units. Continuous resources (such as civil service or contractor program functions) are defined as enabling functional units. Concepts of fixed and variable costs are included in the model to allow the discrete events to interact with cost calculations. The definition file is intrinsic to the model, but a blank start can be initiated at any time. The current definition file is an Orion Ares I crew launch vehicle. Parameters stretch from Kennedy Space Center across and into other program entities (Michaud Assembly Facility, Aliant Techsystems, Stennis Space Center, Johnson Space Center, etc.) though these will only gain detail as the file continues to evolve. The Orion Ares I file definition in the tool continues to evolve, and analysis from this tool is expected in 2008. This is the first application of such business-driven modeling to a NASA/government-- aerospace contractor endeavor.

    Although the misuse of firearms is necessary to the occurrence of firearm violence, there are other contributing factors beyond simply firearms themselves that might also be modified to prevent firearm violence. Alcohol is one such key modifiable factor. To explore this, we undertook a 40-year (1975-2014) systematic literature review with meta-analysis. One large group of studies showed that over one third of firearm violence decedents had acutely consumed alcohol and over one fourth had heavily consumed alcohol prior to their deaths. Another large group of studies showed that alcohol was significantly associated with firearm use as a suicide means. Two controlled studies showed that gun injury after drinking, especially heavy drinking, was statistically significant among self-inflicted firearm injury victims. A small group of studies investigated the intersection of alcohol and firearms laws and alcohol outlets and firearm violence. One of these controlled studies found that off-premise outlets selling takeout alcohol were significantly associated with firearm assault. Additional controlled, population-level risk factor and intervention studies, including randomized trials of which only 1 was identified, are needed. Policies that rezone off-premise alcohol outlets, proscribe blood alcohol levels and enhance penalties for carrying or using firearms while intoxicated, and consider prior drunk driving convictions as a more precise criterion for disqualifying persons from the purchase or possession of firearms deserve further study.

  7. Alcohol fuels for developing countries

    International Nuclear Information System (INIS)

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

  8. Alcohol myopia and goal commitment

    Directory of Open Access Journals (Sweden)

    A.TimurSevincer

    2014-03-01

    Full Text Available According to alcohol-myopia theory, acute alcohol consumption leads people to disproportionally focus on the salient rather than the peripheral aspects of a situation. We summarize various studies exploring how myopic processes resulting from acute alcohol intake affect goal commitment. After consuming alcohol student participants felt strongly committed to an important personal goal even though they had low expectations of successfully attaining the goal. However, once intoxicated participants were sober again (i.e., not myopic anymore they failed to act on their goal commitment. In line with alcohol-myopia theory, strong goal commitment as a result of alcohol intake was mediated by intoxicated (vs. sober participants disproportionally focusing on the desirability rather than the feasibility of their goal. Further supporting alcohol-myopia theory, when the low feasibility of attaining a particular goal was experimentally made salient (either explicitly or implicitly by subliminal priming, intoxicated participants felt less committed than those who consumed a placebo. We discuss these effects of acute alcohol intake in the context of research on the effects of chronic alcohol consumption on goal commitment.

  10. Fast internal dynamics in alcohol dehydrogenase

    International Nuclear Information System (INIS)

    Large-scale domain motions in alcohol dehydrogenase (ADH) have been observed previously by neutron spin-echo spectroscopy (NSE). We have extended the investigation on the dynamics of ADH in solution by using high-resolution neutron time-of-flight (TOF) and neutron backscattering (BS) spectroscopy in the incoherent scattering range. The observed hydrogen dynamics were interpreted in terms of three mobility classes, which allowed a simultaneous description of the measured TOF and BS spectra. In addition to the slow global protein diffusion and domain motions observed by NSE, a fast internal process could be identified. Around one third of the protons in ADH participate in the fast localized diffusive motion. The diffusion coefficient of the fast internal motions is around two third of the value of the surrounding D2O solvent. It is tempting to associate the fast internal process with solvent exposed amino acid residues with dangling side chains

  11. Selectively tritiated primary alcohols

    International Nuclear Information System (INIS)

    A procedure is suggested for the preparation of aliphatic primary alcohols selectively tritiated in the alpha position. The tritium donor is HTO; out of the catalysts tested, dichlorotris(triphenylphosphine)ruthenium(VI) gave the best results. The isotopic exchange can be performed over the temperature region of 130-200 degC. The amount of side products formed is negligible. The specific activity of the product is determined by the specific activity of HTO used and by the reactant ratio. The method is analogous to the reaction with D2O described by S.L. Regen in 1974.

  12. The alcohol withdrawal syndrome.

    LENUS (Irish Health Repository)

    McKeon, A

    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.

    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

    Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children’s drinking behavior in mid-adolescence are mediated by the children’s alcohol expectancies in early adolescence. A sample of 148 initially 9–11 year old boys and their parents from a high-risk population and a contrast group of communit...

    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...

    2005-01-01

    Anna Freud defined adolescence "evolutional disorder", meaning also a compulsory and temporary shift. Corresponding, biologically, to the puberty, it is an age full of expectations and hopes, nevertheless not free from psychological and social risks: because of a changing relation with family, of the searching of new models, of the coming in contact with less protective contexts, of the differentiation of affective expectations. Therefore it can be that the passing from childhood to active subjectivity brings on anxiety, conflicts and deviance; and it can suggest illusory remedies as overindulgence in alcohol, alarming phenomenon denounced by WHO and by many other international and Italian institutions. After these preliminary remarks, the A. reminds as alcohol and its by-products reached Europe, describes its metabolism and its biological effects, the genetic factors which could predispose to the tolerance and/or to the addiction, the environmental and social ones, and the costs, both individual and public. Conclusions want suggest two omens: the reclamation of a new kind of family relation, based on listening and dialogue; and the achievement of a concrete alliance between society and young adult, which could conjugate the expectations of the community with the rights of the new subject for a free and integrated growing up.

    Alcohol use disorder (AUD) and its sequelae impose a major burden on the public health of the United States, and adequate long-term control of this disorder has not been achieved. Molecular and behavioral basic science research findings are providing the groundwork for understanding the mechanisms underlying AUD and have identified multiple candidate targets for ongoing clinical trials. However, the translation of basic research or clinical findings into improved therapeutic approaches for AUD must become more efficient. Translational research is a multistage process of streamlining the movement of basic biomedical research findings into clinical research and then to the clinical target populations. This process demands efficient bidirectional communication across basic, applied, and clinical science as well as with clinical practitioners. Ongoing work suggests rapid progress is being made with an evolving translational framework within the alcohol research field. This is helped by multiple interdisciplinary collaborative research structures that have been developed to advance translational work on AUD. Moreover, the integration of systems biology approaches with collaborative clinical studies may yield novel insights for future translational success. Finally, appreciation of genetic variation in pharmacological or behavioral treatment responses and optimal communication from bench to bedside and back may strengthen the success of translational research applications to AUD.

    The vending machines which sell alcohol beverages (AVM) can be found quite easily in front of shops or on the roadside in this country. Although it is easily supposed that these vending machines might have badly influenced on developing alcohol dependence syndrome, no scientific study has been reported in this regard so far. In this study, we analyzed the present status of alcoholics (n = 759) and their family members (n = 512) and of ordinary people (n = 334) in terms of their "relation" and "attitudes" to the vending machines by a questionnaire method. The results obtained show as follows: The majority of alcoholics (60%) had used AVM a couple of times or more often in a week, and 18% of alcoholics had not used AVM at all. It was found that the natures of AVM such as "machine," "long time operation," "easy accessibility," are closely related to the development of their alcohol seeking behavior, resulting in forming unfavorable drinking patterns such as concealed drinking, gulping, early morning drinking or binge drinking. Unusual patterns of using AVM were also noticed among them, such as, go to AVM before 5 a.m. and wait until it starts to work, go to a far away AVM deliberately, or, visiting AVM one after another. It was noticed that these drinking habits affected seriously not only the alcoholics but their families also. The number of the family members who insisted that AVM affected badly on the course of alcohol dependence syndrome is larger than that of alcoholics who admit the same thing. As for the future abolition of AVM, 91% of the family members, 70% of alcoholics and 39% of ordinary persons agreed with. The rate of "agreed with abolition" is higher than that of "disagreed with abolition" among ordinary persons. PMID:7695515

  13. Volumes of chain links

    Kaiser, James; Rollins, Clint

    2011-01-01

    Agol has conjectured that minimally twisted n-chain links are the smallest volume hyperbolic manifolds with n cusps, for n at most 10. In his thesis, Venzke mentions that these cannot be smallest volume for n at least 11, but does not provide a proof. In this paper, we give a proof of Venzke's statement. The proof for n at least 60 is completely rigorous. The proof for n between 11 and 59 uses a computer calculation, and can be made rigorous for manifolds of small enough complexity, using methods of Moser and Milley. Finally, we prove that the n-chain link with 2m or 2m+1 half-twists cannot be the minimal volume hyperbolic manifold with n cusps, provided n is at least 60 or |m| is at least 8, and we give computational data indicating this remains true for smaller n and |m|.

  15. Extended linear chain compounds

    CERN Document Server

    Linear chain substances span a large cross section of contemporary chemistry ranging from covalent polymers, to organic charge transfer com­ plexes to nonstoichiometric transition metal coordination complexes. Their commonality, which coalesced intense interest in the theoretical and exper­ imental solid state physics/chemistry communities, was based on the obser­ vation that these inorganic and organic polymeric substrates exhibit striking metal-like electrical and optical properties. Exploitation and extension of these systems has led to the systematic study of both the chemistry and physics of highly and poorly conducting linear chain substances. To gain a salient understanding of these complex materials rich in anomalous aniso­ tropic electrical, optical, magnetic, and mechanical properties, the conver­ gence of diverse skills and talents was required. The constructive blending of traditionally segregated disciplines such as synthetic and physical organic, inorganic, and polymer chemistry, crystallog...

    1991-01-01

    Charts of 108 consecutive adult patients with flame burns of 20% to 70% total body surface area were reviewed to determine the incidence of acute alcohol intoxication and the likelihood that intoxicated patients were chronic alcohol abusers, to assess morbidity and mortality in the alcoholic patient with burns, and to characterize the intervention used in postdischarge treatment of the alcoholic patient with burns who survives. Twenty-seven percent of patients were acutely intoxicated at the time of injury. Evidence for chronic alcohol abuse was apparent in 90% of intoxicated patients, compared to only 11% of nonintoxicated patients (p = 0.0001). Alcoholic patients with burns not only had an overall mortality rate three times that of nonalcoholics (p = 0.001) but also died of smaller burns (p less than 0.05). Surviving alcoholic patients with burns required significantly more intravenous antibiotics and a longer hospitalization. Social service evaluation of use of alcohol was made in 84% of the cases of surviving intoxicated burn victims. Further intervention was undertaken in two thirds of these cases, usually involving an outpatient treatment program. PMID:2050723

    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.

  11. Alcohol misuse and renal damage.

    Science.gov (United States)

    Cecchin, E; De Marchi, S

    1996-01-01

    Recent clinical and experimental studies have demonstrated that the habitual consumption of large amounts of ethanol has deleterious effects on the kidney. A variety of tubular defects have been described in patients with chronic alcoholism. Evidence is emerging that tubular dysfunction has an important pathophysiological role in a wide range of electrolyte and acid-base disturbances commonly observed in these patients, and possibly in alcohol-induced bone disease. These renal abnormalities are often reversible, disappearing with abstinence. However, since 1990 a few cases of a syndrome of acute tubular necrosis due to binge drinking of ethanol in the absence of other evident nephrotoxic mechanisms, or in association with the use of nonsteroidal anti-inflammatory drugs, have been reported. A link between glomerulonephritis and alcoholism has become evident. IgA nephropathy has been demonstrated at autopsy in 64% of chronic alcoholics and, more recently, the association between alcoholism and postinfectious glomerulonephritis has been described. Structural and functional abnormalities of the kidney are reported with increasing frequency in the fetal alcohol syndrome seen in children who have been prenatally exposed to ethanol. In addition, over the last few years experimental studies in vitro or in animal models have provided information about the biochemical and molecular basis of alcohol-induced injury to kidney. It is hoped that future experimental and clinical research will provide us with a more comprehensive knowledge of the mechanisms of renal damage in alcohol misuse. PMID:12893483

  12. Swelling behaviour of amphiphilic poly (methacryloxyethl dimethylalkane ammonium bromide) gels in alcohol/water solvent systems

    International Nuclear Information System (INIS)

    Three kinds of amphiphilic PMADAB gels were prepared through radiation-induced polymerization and crosslinking of methacryloxyethyl dimethylalkane ammonium bromide (MADAB) with different alkyl side chains (butyl, octyl and dodecyl). The length of alkyl side chains had significant influence on swelling behavior of the PMADAB gels in alcohol/water solvent. Equilibrium swelling degree (EDS) of PMBDAB (butyl) gel in water was ca. 160 and decreased with increasing alcohol content (x), whereas EDS of PMODAB (octyl) and PMDDDAB (dodecyl) gels showed a convex-upward function of x, i.e., these two gels barely swelled in pure water and swelled with increasing x and then shrank gradually. This phenomenon was explained by the hydrophobic association of long alkyl chains and a cosolvency effect of PMADAB in alcohol and water. The swelling behavior of PMADAB gels in methanol, ethanol and isopropanol were similar, and their EDS are related with the dielectric constant of alcohol solvents. The results suggest that PMADAB gels may be potential absorbents for various kinds of alcohols. (authors)

  13. Hemolysis by aliphatic alcohols and saponin measured by the coil planet centrifugation method.

    1989-09-01

    Using the coil planet centrifugation method, the mechanism of hemolysis by alcohols and saponin was investigated. With this technique, erythrocytes are introduced into a gradient of hemolytic agents in saline, which is prepared in a long coiled polyethylene tube. The tube is centrifuged so that the cells move from a low to a high concentration of hemolytic agent. When the cells lyse, they release hemoglobin which remains stationary, and therefore hemolytic potency can be determined spectrophotometrically by the distance the cells move before lysing. We found that alcohols caused hemolysis at a particular concentration, whereas saponin-induced hemolysis was dependent on the amount of saponin accumulated in the environment of the cell. In addition, alcohols with longer carbon chains were more potent hemolytic agents than those with shorter chains, but each additional carbon group produced less of an increase in hemolysis per mole of alcohol. This chain-length dependency is consistent with a previous study on in vivo alcohol-induced hemolysis. The coil planet centrifugation method is also adaptable to comparative studies on the mechanism of other types of hemolysis, such as immune or drug-induced lysis, and to toxicological studies.

    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. PMID:27188823

  18. A 13C nuclear magnetic resonance investigation of the metabolism of leucine to isoamyl alcohol in Saccharomyces cerevisiae

    International Nuclear Information System (INIS)

    The metabolism of leucine to isoamyl alcohol in yeast was examined by 13C nuclear magnetic resonance spectroscopy. The product of leucine transamination, alpha-ketoisocaproate had four potential routes to isoamyl alcohol. The first, via branched-chain alpha-keto acid dehydrogenase to isovaleryl-CoA with subsequent conversion to isovalerate by acyl-CoA hydrolase operates in wild-type cells where isovalerate appears to be an end product. This pathway is not required for the synthesis of isoamyl alcohol because abolition of branched-chain alpha-keto acid dehydrogenase activity in an lpd1 disruption mutant did not prevent the formation of isoamyl alcohol. A second possible route was via pyruvate decarboxylase; however, elimination of pyruvate decarboxylase activity in a pdc1 pdc5 pdc6 triple mutant did not decrease the levels of isoamyl alcohol produced. A third route utilizes alpha-ketoisocaproate reductase (a novel activity in Saccharomyces cerevisiae) but with no role in the formation of isoamyl alcohol from alpha-hydroxyisocaproate because cell homogenates could not convert alpha-hydroxyisocaproate to isoamyl alcohol. The final possibility was that a pyruvate decarboxylase-like enzyme encoded by YDL080c appears to be the major route of decarboxylation of alpha-ketoisocaproate to isoamyl alcohol although disruption of this gene reveals that at least one other unidentified decarboxylase can substitute to a minor extent.

    2004-09-01

    The alcohol ignition interlock is an in-vehicle DWI control device that prevents a car from starting until the operator provides a breath alcohol concentration (BAC) test below a set level, usually .02% (20 mg/dl) to .04% (40 mg/dl). The first interlock program was begun as a pilot test in California 18 years ago; today all but a few US states, and Canadian provinces have interlock enabling legislation. Sweden has recently implemented a nationwide interlock program. Other nations of the European Union and as well as several Australian states are testing it on a small scale or through pilot research. This article describes the interlock device and reviews the development and current status of interlock programs including their public safety benefit and the public practice impediments to more widespread adoption of these DWI control devices. Included in this review are (1) a discussion of the technological breakthroughs and certification standards that gave rise to the design features of equipment that is in widespread use today; (2) a commentary on the growing level of adoption of interlocks by governments despite the judicial and legislative practices that prevent more widespread use of them; (3) a brief overview of the extant literature documenting a high degree of interlock efficacy while installed, and the rapid loss of their preventative effect on repeat DWI once they are removed from the vehicles; (4) a discussion of the representativeness of subjects in the current research studies; (5) a discussion of research innovations, including motivational intervention efforts that may extend the controlling effect of the interlock, and data mining research that has uncovered ways to use the stored interlock data record of BAC tests in order to predict high risk drivers; and (6) a discussion of communication barriers and conceptual rigidities that may be preventing the alcohol ignition interlock from taking a more prominent role in the arsenal of tools used to control

    1995-10-09

    Thirty-five alcoholic families have been studied to investigate the relationship between DNA markers at the monoamine oxidase (MAO) loci and (1) platelet activity levels and (2) alcoholism. A quantitative linkage analysis failed to reveal any evidence that the variation in activity levels cosegregates with the DNA markers. A sib-pair analysis did not reveal a significant excess of MAO haplotype sharing among alcoholic sibs, although the deviation from random sharing was in the direction consistent with an X-linked component. A reanalysis of platelet MAO activity levels in a subset of these families revealed that the lower levels previously found in alcoholics is more likely due to the differences between males and females. Only among males and only when a {open_quotes}broad{close_quotes} definition of alcoholism is used (and MAO activity levels are transformed to normality) does it appear that alcoholics have depressed activities compared to nonalcoholics. Finally, when the confounding due to gender difference is removed, no differences between type I and type II alcoholics are found in these families. 63 refs., 6 tabs.

  3. Temperature effect on 4-aminophtalimide fluorescence in n-alcohols

    International Nuclear Information System (INIS)

    The compound 4-aminophthalimide (4-AP) is a well-known dye used as an environment polarity sensitive probe e.g. in solvation studies. This paper presents the effect of temperature on 4-aminophthalimides steady-state and time-resolved fluorescence in five n-alcohols. It is shown that the hydrogen bonding ability of n-alcohols affects the shifts of steady-state absorption and fluorescence spectra of 4-aminophthalimide at room temperature, and the shifts of fluorescence also at temperatures from the range 180 to 323 K. Temperature is shown to affect the change in hydrogen bond energy that follows 4-AP excitation, in a way dependent on the n-alcohol alkyl chain length. On the other hand, time-resolved results indicate that the temperature dependence of 4-AP deactivation follows mainly from the energy-gap dependent non-radiative deactivation rate. Fluorescence transition dipole moments at room temperature have been found to be slightly dependent on the solvent, but nothing proves that these changes are connected to different hydrogen bonding character of each n-alcohol. Therefore, while the steady-state results provide clear evidence of hydrogen bonding between 4-AP and n-alcohols, the time-resolved results do not show any evident sign of hydrogen bonding, besides the influence of the position of fluorescence emission on the radiative and non-radiative rates. - Highlights: • We show temperature effect on 4-aminophthalimide (4-AP) absorption and emission. • Hydrogen bonds formation between n-alcohols and 4-AP affect steady-state results. • Temperature change influences hydrogen bonds energy. • 4-AP non-radiative deactivation is energy-gap controlled

    The compound 4-aminophthalimide (4-AP) is a well-known dye used as an environment polarity sensitive probe e.g. in solvation studies. This paper presents the effect of temperature on 4-aminophthalimides steady-state and time-resolved fluorescence in five n-alcohols. It is shown that the hydrogen bonding ability of n-alcohols affects the shifts of steady-state absorption and fluorescence spectra of 4-aminophthalimide at room temperature, and the shifts of fluorescence also at temperatures from the range 180 to 323 K. Temperature is shown to affect the change in hydrogen bond energy that follows 4-AP excitation, in a way dependent on the n-alcohol alkyl chain length. On the other hand, time-resolved results indicate that the temperature dependence of 4-AP deactivation follows mainly from the energy-gap dependent non-radiative deactivation rate. Fluorescence transition dipole moments at room temperature have been found to be slightly dependent on the solvent, but nothing proves that these changes are connected to different hydrogen bonding character of each n-alcohol. Therefore, while the steady-state results provide clear evidence of hydrogen bonding between 4-AP and n-alcohols, the time-resolved results do not show any evident sign of hydrogen bonding, besides the influence of the position of fluorescence emission on the radiative and non-radiative rates. - Highlights: • We show temperature effect on 4-aminophthalimide (4-AP) absorption and emission. • Hydrogen bonds formation between n-alcohols and 4-AP affect steady-state results. • Temperature change influences hydrogen bonds energy. • 4-AP non-radiative deactivation is energy-gap controlled.

    The hydrogen bonding interactions between N-methylformamide and primary, secondary, and tertiary alcohols have been studied using the FT1R spectroscopic method. The most likely association complex between alcohol and N-methylformamide is the 1:1 stoichiometric complex formed between the hydroxyl group of alcohol and the carbonyl group of N-methylformamide. The formation constant of the 1:1 complexes has been calculated using the Nash method. It appears that the primary alcohols have larger formation constant compared with the secondary and tertiary alcohols. The results showed that the proton-donating ability of the alcohols decreased in the order: primary>secondary>tertiary, and that the association constant increased with the increase in carbon chain of the alkyl group of alcohols.

    Full Text Available The growing need to address current energy and environmental problems has sparked an interest in developing improved biological methods to produce liquid fuels from renewable sources. While microbial ethanol production is well established, higher chain alcohols possess chemical properties that are more similar to gasoline. Unfortunately, these alcohols (except 1-butanol are not produced efficiently in natural microorganisms, and thus economical production in industrial volumes remains a challenge. Synthetic biology, however, offers additional tools to engineer synthetic pathways in user-friendly hosts to help increase titers and productivity of these advanced biofuels. This review concentrates on recent developments in synthetic biology to produce higher-chain alcohols as viable renewable replacements for traditional fuel.

    The mutagenicities of evaporated residues of alcoholic beverages were tested by the Ames method with the modification of pre-incubation, by using Salmonella typhimurium TA100 and TA98. 12 of 13 brands of whisky were mutagenic to TA100 without S9 mix. Addition of S9 mix decreased or abolished these mutagenicities. 5 brands of brandy and 1 apple brandy were tested, and all showed a similar type of mutagenicity to that of whisky. A fraction of brand-K whisky, containing a major mutagen(s), eluted from XAD-2 column with water, gave 3800 revertants of TA100 per plate at a dose equivalent to 10 ml of whisky. PMID:7012607

  16. The alcohol program

    International Nuclear Information System (INIS)

    The rationale for the launching of the Alcohol Program from sugarcane in Brazil in the mid-1970s is described as an answer to the first ''oil crisis'' as well as a solution to the problem of the fluctuating sugar prices in the international market. The technical characteristics of ethanol as a fuel are given as well as a discussion of the evolution of the cost of production, environmental and social consequences. Regarding costs, ethanol production was close to 100 dollars a barrel in the initial stages of the Program in 1980 falling rapidly due to economies of scale and technological progress to half that value in 1990, followed by a slower decline in recent years. Considering the hard currency saved by avoiding oil importation through the significant displacement of gasoline by ethanol and the decrease in the amount of external debt that the displaced oil importation was able to provide it is possible to demonstrate that the Alcohol Program has been an efficient way of exchanging dollar debt by national currency subsidies which are paid by the liquid fossil fuel users. Even with this economic gains for society, the continuity of the Program is difficult to maintain. Two solutions to this problem are discussed: internal expansion of the use of ethanol and exports to industrialized countries where it could be used as an octane enhancer. The main attractiveness of the Program - the reduction of CO2 emissions as compared to fossil fuels - is stressed, mainly as a solution for industrialized countries to fulfill their commitments with the United Nations Framework Climate Change Convention.

    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 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.

  3. Radiology's value chain.

    Science.gov (United States)

    Enzmann, Dieter R

    2012-04-01

    A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a

  4. Suicidal Behavior and Alcohol Abuse

    Directory of Open Access Journals (Sweden)

    Maurizio Pompili

    2010-03-01

    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.

  5. A statistical model of hydrogen bond networks in liquid alcohols

    Sillrén, Per; Bielecki, Johan; Mattsson, Johan; Börjesson, Lars; Matic, Aleksandar

    2012-03-01

    We here present a statistical model of hydrogen bond induced network structures in liquid alcohols. The model generalises the Andersson-Schulz-Flory chain model to allow also for branched structures. Two bonding probabilities are assigned to each hydroxyl group oxygen, where the first is the probability of a lone pair accepting an H-bond and the second is the probability that given this bond also the second lone pair is bonded. The average hydroxyl group cluster size, cluster size distribution, and the number of branches and leaves in the tree-like network clusters are directly determined from these probabilities. The applicability of the model is tested by comparison to cluster size distributions and bonding probabilities obtained from Monte Carlo simulations of the monoalcohols methanol, propanol, butanol, and propylene glycol monomethyl ether, the di-alcohol propylene glycol, and the tri-alcohol glycerol. We find that the tree model can reproduce the cluster size distributions and the bonding probabilities for both mono- and poly-alcohols, showing the branched nature of the OH-clusters in these liquids. Thus, this statistical model is a useful tool to better understand the structure of network forming hydrogen bonded liquids. The model can be applied to experimental data, allowing the topology of the clusters to be determined from such studies.

  6. Fluidizing and Solidifying Effects of Perfluorooctylated Fatty Alcohols on Pulmonary Surfactant Monolayers.

    Pulmonary surfactant (PS) preparations based mainly on bovine or porcine extracts are commonly administered to patients with neonatal respiratory distress syndrome (NRDS) for therapy. The preparations are sufficiently effective to treat NRDS; however, they are associated with a risk of infection and involve costly purification procedures to achieve batch-to-batch reproducibility. Therefore, we investigated the mechanism and interfacial behavior of synthetic PS preparations containing a mimicking peptide (KLLKLLLKLWLKLLKLLL, Hel 13-5). In particular, a hybrid PS formulation with fluorinated amphiphiles is reported from the perspective of surface chemistry. Fluorinated amphiphiles are characterized by exceptional chemical and biological inertness, high oxygen-dissolving capacity, low surface tension, excellent spreading ability, and high fluidity. These properties are superior to those for the corresponding hydrocarbon analogs. Indeed, a small amount of fluorinated long-chain alcohols enhances the effectiveness of the model PS preparation for in vitro pulmonary functions. Moreover, the mode of the improved efficacy differs depending on the hydrophobic chain length in the alcohols. For alcohols with a short fluorocarbon (FC) chain, the monolayer phase of the model PS preparation remains disordered (fluidization). However, the addition of alcohols containing a long FC chain reduces the disordered/ordered phase transition pressure and the growth of ordered domains of the monolayer (condensation). Furthermore, repeated compression-expansion isotherms of the monolayers, which can simulate respiration in the lung, suggest irreversible elimination of the short-FC alcohol into the subphase and enhancement of the squeeze-out phenomenon of certain PS components by solid-like monolayer formation induced by the long-FC alcohol. We demonstrated that fluorinated amphiphiles may be used as additives for synthetic or commercial PS preparations for RDS treatment. PMID:26833282

    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.

  12. Alcoholism between Fiction and Reality.

    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. PMID:23485899

    The aim of this work is to evaluate the effects of molecular weight, hydrolysis degree, and cross-link on the performance of Polyvinyl Alcohol (PVA) when applied as dielectric material in organic field effect transistors. For this purpose, metal–insulator-structures and polymeric films were characterized. The polymer structure was analyzed by thermogravimetry and calorimetry, and the electrical characterization of the films was performed through current–voltage and capacitance–voltage curves; and dielectric spectrometry. Cross-linkage, followed by hydrolysis degree, presented the major impact on polymer properties, due to the strong influence on chain mobility. The chain mobility increases the dielectric response and decreases the insulation capacity, generating the need to compromise between these two properties. The largest drawback encountered was the high sensitivity of the films to ambient humidity. The best performance of the organic insulator was obtained from cross-linked films made of an incompletely hydrolyzed PVA. - Highlights: • Effect of molecular weight, hydrolysis and cross-link on polyvinyl alcohol (PVA) dielectric • Cross-linkage, followed by hydrolysis, showed the major impact on properties. • Cross-linkage followed by hydrolysis showed the strongest effect on chain mobility. • Best dielectric performance: cross-linked films made of incompletely hydrolyzed PVA • Largest drawback is the high sensitivity of the films to ambient humidity

    Full Text Available Alcohol consumption has widely increased through out the world. This all is due to a stressful life style and emotional load on a person. Dentistry is not excluded from the stress phenomenon. Dentists experience stressful situations every day, and have to deal with these in a very professional manner. The dentists participated were told about the hazard and ill-effect of alcohol consumption. There need to be a reduction in consumption of alcohol in dentistry for the upliftment of general masses as well as the dentist.

  18. Pathogenesis of Alcoholic Liver Disease.

    2016-08-01

    Alcoholic liver disease includes a broad clinical-histological spectrum from simple steatosis, cirrhosis, acute alcoholic hepatitis with or without cirrhosis to hepatocellular carcinoma as a complication of cirrhosis. The pathogenesis of alcoholic liver disease can be conceptually divided into (1) ethanol-mediated liver injury, (2) inflammatory immune response to injury, (3) intestinal permeability and microbiome changes. Corticosteroids may improve outcomes, but this is controversial and probably only impacts short-term survival. New pathophysiology-based therapies are under study, including antibiotics, caspase inhibition, interleukin-22, anakinra, FXR agonist and others. These studies provide hope for better future outcomes for this difficult disease. PMID:27373608

  19. Alcohol Withdrawal Mimicking Organophosphate Poisoning

    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.

  20. Correlations Between retention indices and molecular structure of aliphatic alcohols and of their benzoyl derivatives on phenyl substituted polysiloxane stationary phases

    International Nuclear Information System (INIS)

    The retention indices of aliphatic alcohols of carbon number up to Cg, and of their benzoyl derivatives up to C7, were determined in columns packed with Chromo sorb G (AW-DMCS-HP) coated previously with 5% methyl, and methyl phenyl polysiloxanes with increasing polarity (SE-30, 0V-3, 0V-7, 0V-11, 0V-17 and OV-25). Correlations between retention indices and chain length for 1-alcohols, 2-alcohols, 3-alcohols, 1 , on -3-alcohols, 2-methyl-1-alcohols and for their corresponding benzoyl derivatives were calculated at 100, 120 and 140 degree centigree. In alcohols, a -CH2- group increases I approximately 100 units, and in their benzoyl derivatives from 80 to 100 units. Dispersion indices Δl , and positional and structural increments δI, were evaluated for -OH and benzoyl groups in terms of phase polarity and chain length. Effects of chain length, chain branching and double bond location on retention parameters were also studied. (Author) 23 refs

  1. Palm-based lauryl alcohol ethoxylate behavioural study and recommendations in personal care applications

    International Nuclear Information System (INIS)

    Palm-based lauryl alcohol ethoxylate was synthesized with 6 moles of ethylene oxide using an ethoxylation reactor. The 6 moles of ethylene oxide chain length was approximately the same length as the palm-based lauryl alcohol. The synthesized lauryl alcohol ethoxylate consisted of an average of 6 moles of ethylene oxide and was labeled as C12EO6. The molecular structure of lauryl alcohol ethoxylate was determined by Fourier Transformed Infrared Spectroscopy (FTIR). The ternary phase diagrams for olive or olein oil/water/C12E6 systems were investigated at 25 degree Celsius. The important features of the ternary phase diagrams are the emulsion and the concentrated emulsion phases. Optical microscope, particle size analyser and rheometer were used to characterize the different compositions of emulsions. Different consistencies of emulsions were recommended for the personal care applications. (author)

  2. The economic impact of alcohol abuse and alcoholism.

    Burke, T. R.

    1988-01-01

    The economic effects of alcohol abuse are as damaging to the nation as the health effects, affecting the family, the community, and persons of all ages. Underaged drinking is interfering with children's development, affecting the nation's ability to respond to economic challenge in the future. The college aged may be the most difficult to educate about alcohol abuse because of drinking patterns established at an early age and susceptibility to advertising inducements. Health care costs for fa...

  3. Alcohol Advertising Bans and Alcohol Abuse: An International Perspective

    OpenAIRE

    Henry Saffer

    1989-01-01

    The purpose of this paper is to empirically examine the effect on alcohol abuse of banning broadcast advertising of alcoholic beverages. The effect of a ban cannot be studied using data from one country because the adoption of new advertising bans is an infrequent event and requires many years for adjustment. However, an international data set can be used since there is considerable variation in the use of advertising bans across countries. The data used in this study are a pooled time series...
