    Aerobic soil biodegradation of toluene-2,4-di(8:2 fluorotelomer urethane) (FTU) and hexamethylene-1,6-di(8:2 fluorotelomer urethane) (HMU) in a forest soil and FTU in an agricultural silty clay loam soil was monitored for up to 6 months. Fluorotelomer alcohols were measured in headspace and parent monomers and all metabolites in soil extracts. Negligible degradation of FTU biodegradation occurred in the agricultural soil with 94 ± 15% recovered at day 180. However, in the forest soil, both FTU and HMU degradation was evident with significant losses of 24% (117 d) and 27% (180 day), respectively, and concomitant increases in the terminal metabolite, perfluorooctanoic acid (PFOA) concentrations were well above what could result from residual 8:2 FTOH. Kinetic modeling estimated half-lives for FTU (aromatic backbone) and HMU (aliphatic backbone) in the forest soil to be 3-5 months and 15.9-22.2 months, respectively. The addition of a structurally similar non-fluorinated FTU analog, toluene-2,4-dicarbamic acid diethyl ester (TDAEE) enhanced production of terminal end products from 8:2 FTOH degradation. However, there was no clear evidence that TDAEE enhanced cleavage of the urethane bond, thus TDAEE appeared to just serve as an additional carbon source. TDAEE's half-life was ∼ one week. A second addition of TDAEE appeared to retard subsequent degradation of FTU exemplifying the microbial dynamics and diversity impacting degradation of polyfluoroalkyl substances. Enhanced degradation of HMU was observed upon re-aeration indicating oxygen may have been limiting during some periods although degradation of intermediate metabolites to terminal metabolites was still occurring, albeit at slower rates.

    Previous studies have demonstrated that perfluorinated chemicals (PFCs) can affect reproduction by disruption of steroidogenesis in experimental animals. However, the underlying mechanism(s) of this disruption remain unknown. Here we investigated the effects and mechanisms of action of 1H, 1H, 2H, 2H-perfluoro-decan-1-ol (8:2 FTOH) on steroidogenesis using a human adrenocortical carcinoma cell line (H295R) as a model. H295R cells were exposed to 0, 7.4, 22.2 or 66.6 {mu}M 8:2 FTOH for 24 h and productions of progesterone, 17{alpha}-OH-progesterone, androstenedione, testosterone, deoxycorticosterone, corticosterone and cortisol were quantified by HPLC-MS/MS. With the exception of progesterone, 8:2 FTOH treatment significantly decreased production of all hormones in the high dose group. Exposure to 8:2 FTOH significantly down-regulated cAMP-dependent mRNA expression and protein abundance of several key steroidogenic enzymes, including StAR, CYP11A, CYP11B1, CYP11B2, CYP17 and CYP21. Furthermore, a dose-dependent decrease of cellular cAMP levels was observed in H295R cells exposed to 8:2 FTOH. The observed responses are consistent with reduced cellular cAMP levels. Exposure to 8:2 FTOH resulted in significantly less basal (+ GTP) and isoproterenol-stimulated adenylate cyclase activities, but affected neither total cellular ATP level nor basal (-GTP) or NaF-stimulated adenylate cyclase activities, suggesting that inhibition of steroidogenesis may be due to an alteration in membrane properties. Metabolites of 8:2 FTOH were not detected by HPLC-MS/MS, suggesting that 8:2 FTOH was not metabolized by H295R cells. Overall, the results show that 8:2 FTOH may inhibit steroidogenesis by disrupting the cAMP signalling cascade.

    Biotransformation of fluorotelomer (FT) compounds, such as 8:2 FT alcohol (FTOH) is now recognized to be a source of perfluorooctanoic acid (PFOA) as well as other perfluoroalkyl acids. In this study, microbially mediated hydrolysis of FT industrial intermediates 8:2 FT acrylate (8:2 FTAC) and 8:2 FT methacrylate (8:2 FTMAC) was evaluated in aerobic soils for up to 105d. At designated times, triplicate microcosms were sacrificed by sampling the headspace for volatile FTOHs followed by sequential extraction of soil for the parent monomers as well as transient and terminal degradation products. Both FTAC and FTMAC were hydrolyzed at the ester linkage as evidenced by 8:2 FTOH production. 8:2 FTAC and FTMAC degraded rapidly with half-lives ⩽5d and 15d, respectively. Maximum 8:2 FTOH levels were 6-13mol% within 3-6d. Consistent with the known biotransformation pathway of 8:2 FTOH, FT carboxylic acids and perfluoroalkyl carboxylic acids were subsequently generated including up to 10.3mol% of PFOA (105d). A total mass balance (parent plus metabolites) of 50-75mol% was observed on the last sampling day. 7:2 sFTOH, a direct precursor to PFOA, unexpectedly increased throughout the incubation period. The likely, but unconfirmed, concomitant production of acrylic acids was proposed as altering expected degradation patterns. Biotransformation of 8:2 FTAC, 8:2 FTMAC, and previously reported 8:2 FT-stearate for the same soils revealed the effect of the non-fluorinated terminus group linked to the FT chain on the electronic differences that affect microbially-mediated ester cleavage rates.

    Levels of perfluorinated carboxylates (PFCAs) in different environmental and biological compartments have been known for some time, but the routes of exposure still remain unclear. The opinions are divergent whether the exposure to general populations occurs mainly indirect through precursor compounds or direct via PFCAs. Previous results showed elevated blood levels of PFCAs in ski wax technicians compared to a general population. The objective of this follow-up study was to determine concentrations of PFCAs, perfluorosulfonates (PFSAs), and fluorotelomer alcohols (FTOHs), precursor compounds that are known to degrade to PFCAs, in air collected in the breathing zone of ski wax technicians during work. We collected air samples by using ISOLUTE ENV+ cartridges connected to portable air pumps with an air flow of 2.0 L min(-1). PFCAs C5-C11 and PFSAs C4, C6, C8, and C10 were analyzed using LC-MS/MS and FTOHs 6:2, 8:2, and 10:2 with GC-MS/MS. The results show daily inhalation exposure of 8:2 FTOH in μg/m(3) air which is up to 800 times higher than levels of PFOA with individual levels ranging between 830-255000 ng/m(3) air. This suggests internal exposure of PFOA through biotransformation of 8:2 FTOH to PFOA and PFNA in humans.

    Here, we developed and validated a headspace-solid-phase microextraction-gas chromatography/mass spectrometry (HS-SPME-GC/MS) method for the determination of 14 volatile perfluorinated alkylated substances (PFASs) in water and sediment samples according to SANTE 11945/2015 guidelines. Three fluorotelomer alcohols (FTOHs), two perfluoroalkyl iodides (PFIs), three fluorotelomer iodides (FTIs), four fluorotelomer acrylates and methacrylates (FTACs and FTMACs) and two perfluoroalkyl sulfonamides (FASAs) were analysed simultaneously to assess the occurrence of these compounds from their emission sources to the outlets in water treatment plants. Several SPME parameters were optimised for both water and sediment to maximise responses and keep analysis time to a minimum. In tap water, the limits of quantification (LOQs) were found to be between 20ng/L and 100ng/L depending on the analyte, with mean recoveries ranging from 76 to 126%. For sediments, LOQs ranged from 1 to 3ng/g dry weight depending on the target compound, with mean recoveries ranging from 74 to 125%. SPME considerably reduced sample preparation time and its use provided a sensitive, fast and simple technique. We then used this HS-SPME-GC/MS method to investigate the presence of volatile PFASs in the vicinity of an industrial facility. Only 8:2 FTOH and 10:2 FTOH were detected in a few water and sediment samples at sub-ppb concentration levels. Moreover, several non-target fluorotelomers (12:2 FTOH, 14:2 FTOH and 10:2 FTI) were identified in raw effluent samples. These long-chain fluorotelomers have high bioaccumulative potential in the aquatic environment compared with short-chain fluorotelomers such as 6:2 FTOH and 6:2 FTI. PMID:27125188

    The biotransformation of fluorotelomer-based compounds such as fluorotelomer alcohols (FTOHs) and polyfluoroalkyl phosphate esters (PAPs) are sources of exposure to perfluorinated carboxylates (PFCAs), leading in part to the observation of significant concentrations of PFCAs in human blood. The biotransformation of FTOHs and PAPs yield intermediate metabolites that have been observed to covalently modify proteins. In the current investigation, the extent of covalent protein binding in Sprague-Dawley rats upon exposure to 8:2 FTOH and the 6:2 polyfluoroalkyl phosphate diester (6:2 diPAP) was quantified. The animals were administered a single dose of 8:2 FTOH or 6:2 diPAP at 100 mg/kg by oral gavage to monitor biotransformation and extent of protein binding within the liver, kidney, and plasma. In the 8:2 FTOH-dosed animals, perfluorooctanoate (PFOA) was produced as the primary PFCA, at 623.13 ± 59.3, 459.5 ± 171.8, and 397.3 ± 133.0 ng/g in the plasma, liver, and kidney, respectively. For the animals exposed to 6:2 diPAPs, perfluorohexanoate (PFHxA) was the primary PFCA produced, with maximum concentrations of 57.4 ± 6.5, 9.0 ± 1.2, and 25.3 ± 1.2 ng/g in the plasma, liver, and kidney, respectively. Protein binding was observed in the plasma, liver, and kidney after 8:2 FTOH and 6:2 diPAP exposure, with the most significant binding occurring in the liver (>100 nmol/g protein). This is the first study to link the exposure and in vivo biotransformation of fluorotelomer-based compounds to covalent protein binding.

    The presence of perfluorinated carboxylic acids (PFCAs) in Arctic environments has been proposed to arise in part from the atmospheric oxidation of fluorotelomer alcohols (FTOHs), a class of fluorinated compounds used in a variety of commercial and industrial applications. The main atmospheric loss process for FTOHs is believed to be gas-phase OH oxidation, against which they have a lifetime of ~ 20 days. However, the existence of significant urban-rural gradients in gas-phase FTOH concentrations suggests that this class of compounds may be subject to additional loss processes. One possibility is that FTOHs may be oxidized at the surface of semiconductor-containing aerosols. In the present study, we investigate the uptake and photochemistry of a suite of fluorinated alcohols at the surface of TiO2, Mauritanian sand, and Icelandic volcanic ash. The test compounds 3,3,3-trifluoropropanol, 4:2 FTOH, and 6:2 FTOH each exhibit substantial uptake to these surfaces. Furthermore, at the illuminated TiO2 surface, we find that the photooxidation of 3,3,3-trifluoropropanol yields the corresponding aldehyde, and that this reaction is enhanced in the presence of co-sorbed nitrate. This latter observation provides evidence that the processing of mineral dust, which is known to deposit nitrate at the dust surface, may enhance its photochemical reactivity.

    Fluorotelomer alcohols [FTOHs, F(CF(2))(n) CH(2)CH(2)OH, n = 4, 6, and 8] are emerging environmental contaminants. Biotransformation of FTOHs by mixed bacterial cultures has been reported; however, little is known about the microorganisms responsible for the biotransformation. Here we reported biotransformation of FTOHs by two well-studied Pseudomonas strains: Pseudomonas butanovora (butane oxidizer) and Pseudomonas oleovorans (octane oxidizer). Both strains could defluorinate 4:2, 6:2, and 8:2 FTOHs, with a higher degree of defluorination for 4:2 FTOH. According to the identified metabolites, P. oleovorans transformed FTOHs via two pathways I and II. The pathway I led to the production of x:2 ketone [dominant metabolite, F(CF(2))(x)C(O)CH(3); x = n - 1, n = 6 or 8], x:2 sFTOH [F(CF(2))(x)CH(OH)CH(3)], and perfluorinated carboxylic acids (PFCAs, perfluorohexanoic, or perfluorooctanoic acid). The pathway II resulted in the formation of x:3 polyfluorinated acid [F(CF(2))(x) C(2)CH(2) COOH] and relatively minor shorter-chain PFCAs (perfluorobutyric or perfluorohexanoic acid). Conversely, P. butanovora transformed FTOHs by using the pathway I, leading to the production of x:2 ketone, x:2 sFTOH, and PFCAs. This is the first study to show that individual bacterium can bio-transform FTOHs via different or preferred transformation pathways to remove multiple --CF(2) -- groups from FTOHs to form shorter-chain PFCAs.

    The U.S. Environmental Protection Agency (EPA) has established an ongoing effort to identify the major perfluorocarboxylic acid (PFCA) sources in nonoccupational indoor environments and characterize their transport and fate. This study determined the concentrations of fluorotelomer alcohols (FTOHs), which are the precursors to PFCAs, in fifty-four consumer products collected from the U.S. open market in the years of 2011 and 2013. The products included carpet, commercial carpet-care liquids, household carpet/fabric-care liquids, treated apparel, treated home textiles, treated non-woven medical garments, floor waxes, food-contact paper, membranes for apparel, and thread-sealant tapes. The FTOHs quantified were 1H,1H,2H,2H-perfluoro-1-octanol (6:2 FTOH), 1H,1H,2H,2H-perfluoro-1-decanol (8:2 FTOH), and 1H,1H,2H,2H-perfluoro-1-dodecanol (10:2 FTOH). The content of 6:2 FTOH ranged from non-delectable to 331μgg(-1), 8:2 FTOH from non-delectable to 92μgg(-1), and 10:2 FTOH from non-detectable to 24μgg(-1). In addition, two consumer products from the home textile category were tested in the washing-drying process. One product from the treated apparel category and one from the home textile category were tested in the micro-scale chamber under elevated temperatures. The experimental data show that the washing-drying process with one cycle did not significantly reduce the FTOH concentrations in the tested consumer products. FTOH off-gassing was observed under accelerated aging conditions. Future tests should include air sampling to allow determination of the absolute emission rates at different temperatures. The results of this study should be informative to exposure assessment and risk management. PMID:24997516

    Ionization and in source-fragmentation behavior of four fluorotelomer alcohols (FTOH) (4:2 FTOH, 6:2 FTOH, 8:2 FTOH and 10:2 FTOH) and four N-alkyl fluorooctane sulfonamides/-ethanols (N-MeFOSA, N-EtFOSA, N-MeFOSE and N-EtFOSE) by APCI has been studied and compared with the traditionally used EI and CI. Protonated molecule was the base peak of the APCI spectrum in all cases giving the possibility of selecting it as a precursor ion for MS/MS experiments. Following, CID fragmentation showed common product ions for all FOSAs/FOSEs (C4F7 and C3F5). Nevertheless, the different functionality gave characteristic pattern fragmentations. For instance, FTOHs mainly loss H2O+HF, FOSAs showed the losses of SO2 and HF while FOSEs showed the losses of H2O and SO2. Linearity, repeatability and LODs have been studied obtaining instrumental LODs between 1 and 5fg. Finally, application to river water and influent and effluent waste water samples has been carried out in order to investigate the improvements in detection capabilities of this new source in comparison with the traditionally used EI/CI sources. Matrix effects in APCI have been evaluated in terms of signal enhancement/suppression when comparing standards in solvent and matrix. No matrix effects were observed and concentrations found in samples were in the range of 1-100pgL(-1) far below the LODs achieved with methods previously reported. Unknown related perfluoroalkyl substances, as methyl-sulfone and methyl-sulfoxide analogues for FTOHs, were also discovered and tentatively identified.

    Degradation of fluorotelomer alcohols (FTOHs) was recognized as an additional source of perfluorocarboxylic acids (PFCAs). Quantification of FTOHs and their degradation products can help shed light on the sources and fates of PFCAs in the environment. In this study, an analytical method was developed for the determination of 6:2 and 8:2 FTOHs, and their degradation products of poly- and perfluorinated acids, including fluorotelomer saturated and unsaturated carboxylic acids (FTCAs and FTUCAs), secondary polyfluorinated alcohols and PFCAs in biosolids-amended soils and plants using ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The extract efficiencies of different methods including ethyl acetate and methanol (MeOH) for FTOHs and acetonitrile, MeOH, methyl tert-butyl ether (MTBE), NaOH-MeOH and NaOH-MTBE for poly- and perfluorinated acids were tested. The results showed that 6:2 and 8:2 FTOHs and their degradation products could be simultaneously and satisfactorily extracted by MeOH, cleaned up by Envi-Carb graphitized carbon and solid phase extraction, respectively, and determined by UPLC-MS/MS separately. NaOH in the extractant caused the conversion of 6:2 FTCA and 8:2 FTCA into the corresponding FTUCAs. The selected methods have matrix recoveries ranged from 52% to 102%, and detection limits of 0.01-0.46ng/g dry weight for FTOHs and their degradation products in soil and plant. The optimized method was applied successfully to quantify FTOHs and their degradation products in two biosolids-amended soils and plants. The total concentrations of FTOHs in the soils were 44.1±5.8 and 82.6±7.1ng/g, and in plants tissues 3.58±0.25 and 8.33±0.66ng/g. The total concentrations of poly- and perfluorinated acids in the soils were 168.0±13.2 and 349.6±11.2ng/g, and in plants tissues 78.0±6.4 and 75.5±5.3ng/g. PMID:26070818

The extract efficiencies of different methods including ethyl acetate and methanol (MeOH) for FTOHs and acetonitrile, MeOH, methyl tert-butyl ether (MTBE), NaOH-MeOH and NaOH-MTBE for poly- and perfluorinated acids were tested. The results showed that 6:2 and 8:2 FTOHs and their degradation products could be simultaneously and satisfactorily extracted by MeOH, cleaned up by Envi-Carb graphitized carbon and solid phase extraction, respectively, and determined by UPLC-MS/MS separately. NaOH in the extractant caused the conversion of 6:2 FTCA and 8:2 FTCA into the corresponding FTUCAs. The selected methods have matrix recoveries ranged from 52% to 102%, and detection limits of 0.01-0.46ng/g dry weight for FTOHs and their degradation products in soil and plant. The optimized method was applied successfully to quantify FTOHs and their degradation products in two biosolids-amended soils and plants. The total concentrations of FTOHs in the soils were 44.1±5.8 and 82.6±7.1ng/g, and in plants tissues 3.58±0.25 and 8.33±0.66ng/g. The total concentrations of poly- and perfluorinated acids in the soils were 168.0±13.2 and 349.6±11.2ng/g, and in plants tissues 78.0±6.4 and 75.5±5.3ng/g.

    The occurrence of fluorotelomer alcohols (FTOHs) was investigated in 94 food-contact materials (FCMs). We detected 6:2 FTOH (<0.60-1110 ng/g), 8:2 FTOH (<0.40-8490 ng/g), and 10:2 FTOH (<0.02-9350 ng/g) in most FCM samples, and four longer-chain C14-20 FTOHs were, for the first time, identified in FCMs with relatively high concentrations (<0.02-8450 ng/g for 12:2 FTOH, <0.02-1640 ng/g for 14:2 FTOH, <0.02-372 ng/g for 16:2 FTOH, and <0.02-130 ng/g for 18:2 FTOH). There were three typical profiles of FTOHs that were dominated by 6:2 FTOH (95.6 ± 8.1% in 9 FCMs), 8:2 FTOH (50.9 ± 20.8% in 22 FCMs), and 10:2 FTOH (44.5 ± 20.9% in 30 FCMs), indicating the congener-specific usage of FTOHs for different commercial purposes. All nine detectable FCMs produced in the United States were dominated by 6:2 FTOH, which was significantly different from those produced in China. The median concentration of total FTOHs in eco-friendly paper tableware was 2990 ng/g, which was lower than in popcorn bags (18 200 ng/g) but much higher than other FCMs (<0.55-38.7 ng/g). FTOHs could migrate from paper bowls, with migration efficiencies of 0.004-0.24% into water, 0.004-0.24% into 10% ethanol, 0.009-2.79% into 30% ethanol, 0.06-13.0% into 50% ethanol (v/v) simulants, and 0.04-2.28% into oil. Migration efficiencies decreased with increasing carbon chain lengths of FTOHs. PMID:26655429

    Factors affecting microbial aerobic biodegradation of 6:2 fluorotelomer alcohol [6:2 FTOH, F(CF₂)₆CH₂CH₂OH] were investigated using three alkane-degrading bacteria (Mycobacterium vaccae JOB5, Pseudomonas oleovorans, and Pseudomonas butanovora) and one fluoroacetate-degrading bacterium (Pseudomonas fluorescens DSM 8341). In the presence of formate (an external reducing energy source), P. fluorescens DSM 8341 produced perfluorobutanoic acid by removing three -CF₂- groups from 6:2 FTOH. Only P. fluorescens DSM 8341 transformed 5:3 acid to 4:3 acid and perfluoropentanoic acid. However, formate showed no effects on the degradation rates, patterns, or transformation products of 6:2 FTOH by M. vaccae JOB5. When dicyclopropylketone (an alkane hydroxylase inducer) or formate was added, P. oleovorans rapidly degraded 6:2 FTOH and produced PFPeA. In the presence of lactate, P. butanovora degraded 6:2 FTOH slowly but produced diverse metabolites. Our results demonstrate that the extent and mechanisms of 6:2 FTOH biotransformation are affected by strain types, enzyme inducers, and levels of reducing energy. PMID:23907259

    Saturated and unsaturated fluorotelomer carboxylic acids have been identified as intermediates in the degradation of fluorotelomer alcohols to perfluorinated carboxylic acids (PFCAs). Although surface waters are the likely environmental sink for telomer acids, no fate or toxicity data exist for this matrix. We assessed the acute toxicity of the 4:2, 6:2, 8:2, and 10:2 saturated (FTCA) and unsaturated (FTUCA) fluorotelomer carboxylic acids to Daphnia magna, Chironomus tentans, and Lemna gibba. In general, toxicity increased with increasing fluorocarbon (FC) chain length, particularly for telomer acids of > or =8 FCs. In addition, the FTCAs were generally more toxic than the corresponding FTUCAs. Acute EC50s ranged from 0.025 mg/L (0.04 micromol/L) for D. magna (10:2 FTCA, immobility) to 63 mg/L (167 micromol/L) for C. tentans (6:2 FTCA, growth). While chain-length trends observed in the current study agree with those previously reported for PFCAs, the toxicity thresholds generated here are up to 10,000 times smaller. Our data provide the first evidence that PFCA precursors are more toxic than the PFCAs themselves. PMID:17993163

    Fluorotelomer alcohols (FTOHs) have shown estrogenic activity in vitro and in vivo, but the mechanism of this activity is not known. In this study, 18-week-old zebrafish (Danio rerio) were exposed to 0, 0.03, 0.3 and 3.0mg/l 1H,1H,2H,2H-perfluorooctan-1-ol (6:2 FTOH) for 7 days, and the effects on plasma sex hormone levels were measured followed by use of real-time PCR to examine selected gene expression in hypothalamic-pituitary-gonadal (HPG) axis and liver. Exposure to 6:2 FTOH significantly increased plasma estradiol (E2) and testosterone (T) levels in both males and females. Furthermore, the ratio of T/E2 was reduced in females while increased in males. In females, the increase of E2 was accompanied by up-regulated hepatic estrogenic receptor alpha (ERalpha) and vitellogenin (VTG1 and VTG3) expression. In males, the elevation of the T level is consistent with the up-regulation of cytochrome P450 c17alpha-hydroxylase, 17, 20-lase (CYP17) and the down-regulation of cytochrome P450 aromatase A (CYP19A). The present study demonstrated that waterborne exposure to 6:2 FTOH alter plasma sex hormone levels and the ratio of T/E2, as well as the transcriptional profiles of some genes in the HPG axis and liver. The results suggested that FTOHs may disturb fish reproduction through endocrine disrupted activity.

    Aqueous film-forming foams (AFFF) are complex mixtures containing fluorocarbon- and hydrocarbon-based surfactants that are used to fight hydrocarbon-fueled fires. The military is the largest consumer of AFFF in the United States, and fire-training activities conducted at military bases have led to groundwater contamination by unspent fuels and AFFF chemicals. A direct-injection, liquid-chromatography tandem mass spectrometry (LC MS/MS) method was developed to quantify a suite of fluorotelomer sulfonate surfactants in groundwater collected from military bases where fire-training activities were conducted. The 4:2, 6:2, and 8:2 fluorotelomer sulfonates were detected and quantified in groundwater from two of the three military bases. The total fluorotelomer sulfonate concentrations observed at Wurtsmith AFB, MI, and Tyndall AFB, FL, ranged respectively from below quantitation (< or = 0.60) to 182 microg/L and from 1100 to 14,600 microg/L. Analyses of a fluorotelomer-based AFFF concentrate by negative ion fast atom bombardment/mass spectrometry and LC MS/MS analyses indicate that the AFFF concentrate contains only a small amount of fluorotelomer sulfonates and that fluoroalkylthioamido sulfonates are the main anionic fluorosurfactant in the mixtures. More research is needed to determine the fate of fluoroalkylthioamido sulfonates in the environment.

    The aerobic biotransformation pathways of 4:2, 6:2, and 8:2 fluorotelomer thioether amido sulfonate (FtTAoS) were characterized by determining the fate of the compounds in soil and medium microcosms amended with an aqueous film-forming foam (AFFF) solution. The biotransformation of FtTAoS occurred in live microcosms over approximately 40 days and produced 4:2, 6:2, and 8:2 fluorotelomer sulfonate (FtS), 6:2 fluorotelomer unsaturated carboxylic acid (FtUCA), 5:3 fluorotelomer carboxylic acid (FtCA), and C4 to C8 perfluorinated carboxylic acids (PFCAs). Two biotransformation products corresponding to singly and doubly oxygenated forms of 6:2 FtTAoS were also identified through high resolution mass spectrometry (MS) analysis and liquid chromatography tandem-MS. An oxidative assay was used to indirectly quantify the total concentration of polyfluorinated compounds and check the mass balance. The assay produced near complete mass recovery of FtTAoS after biotransformation, with 10% (mol/mol) of the amended FtTAoS accounted for in FtS, FtCA, and PFCA products. The transformation rates of identified products appear to be slow relative to FtTAoS, indicating that some intermediates may persist in the environment. This study confirms some of the sources of FtS and PFCAs in groundwater and soil at AFFF-impacted sites and suggests that fluorinated intermediates that are not routinely measured during the biotransformation of PFASs may accumulate.

    A method based on LC/MS/MS analysis of fluorotelomer carboxylic acids (FTCAs: CnF2n+1CH2COOH, n = 6, 8, and 10) and fluorotelomer unsaturated carboxylic acids (FTUCAs: CnF2nCHCOOH, n = 6, 8, and 10) in rainwater using negative ionization electrospray multiple reaction monitoring conditions is described. These compounds are thought to be oxidative products of atmospherically transported fluorotelomer alcohols (FTOHs: CnF2n+1CH2CH2CH2OH). Preconcentration from rainwater samples collected in Winnipeg, Manitoba, Canada, was achieved using solid-phase extraction on C18 sorbent. Low parts per trillion levels of the C10- and C12-FTCAs and FTUCAs were detected, suggesting that one possible pathway of removing FTOHs from the atmosphere is through oxidation and wet deposition. Perfluorocarboxylic acids (PFCAs) and perfluorooctane sulfonate (PFOS) were simultaneously analyzed in the rainwater samples using established LC/MS/MS methods. PFOS was deposited in rainwater with a concentration of 0.59 ng/L while PFCAs were not detected above their respective method detection limits.

    This study investigated the biodegradation potential of 3-(14)C,1H,1H,2H,2H-perfluorodecanol [CF3(CF2)6(14)CF2CH2CH2OH, 14C-labeled 8-2 telomer B alcohol or 14C-labeled 8-2 TBA] by diluted activated sludge from a domestic wastewater treatment plant under aerobic conditions. After sample extraction with acetonitrile, biotransformation products were separated and quantified by LC/ARC (on-line liquid chromatography/accurate radioisotope counting) with a limit of quantification about 0.5% of the 14C counts applied to the test systems. Identification of biotransformation products was performed by quadrupole time-of-flight mass spectrometry. Three transformation products have been identified: CF3(CF2)6(14)CF2CH2COOH (8-2 saturated acid); CF3(CF2)6(14)CF=CHCOOH (8-2 unsaturated acid); and CF3(CF2)6(14)COOH (perfluorooctanoic acid, PFOA), representing 27, 6.0, and 2.1% of the initial 14C mass (14C counts applied) after 28 days, respectively. A transformation product, not yet reported in the literature, has also been observed and tentatively identified as CF3(CF2)6(14)CH2CH2COOH (2H,2H,3H,3H-perfluorodecanoic acid); it accounted for 2.3% of the mass balance after 28 days. The 2H,2H,3H,3H-perfluorodecanoic acid is likely a substrate for beta-oxidation, which represents one of the possible pathways for 8-2 telomer B alcohol degradation. The 8-2 saturated acid and 8-2 unsaturated acid cannot be directly used as substrates for beta-oxidation due to the proton deficiency in their beta-carbon (C3 carbon) and their further catabolism may be catalyzed by some other still unknown mechanisms. The 2H,2H,3H,3H-perfluorodecanoic acid may originate either from the major transformation product CF3(CF2)6(14)CF2CH2COOH or from other unidentified transformation products via multiple steps. Approximately 57% of the starting material remained unchanged after 28 days, likely due to its strong adsorption to the PTFE (poly(tetrafluoroethylene)) septa of the test vessels. No CF3(CF2)6(14)CF2COOH

    The SPARC software program and comparative density functional theory (DFT) calculations were used to investigate the aqueous phase hydration equilibrium constants (Khyd) of perfluoroalkyl aldehydes (PFAlds) and n:2 fluorotelomer aldehydes (FTAlds). Both classes are degradation products of known industrial compounds and environmental contaminants such as fluorotelomer alcohols, iodides, acrylates, phosphate esters, and other derivatives, as well as hydrofluorocarbons and hydrochlorofluorocarbons. Prior studies have generally failed to consider the hydration, and subsequent potential hydrate acidity, of these compounds, resulting in incomplete and erroneous predictions as to their environmental behavior. In the current work, DFT calculations suggest that all PFAlds will be dominantly present as the hydrated form in aqueous solution. Both SPARC and DFT calculations suggest that FTAlds will not likely be substantially hydrated in aquatic systems or in vivo. PFAld hydrates are expected to have pKa values in the range of phenols (ca. 9 to 10), whereas n:2 FTAld hydrates are expected to have pKa values ca. 2 to 3 units higher (ca. 12 to 13). In order to avoid spurious modeling predictions and a fundamental misunderstanding of their fate, the molecular and/or dissociated hydrate forms of PFAlds and FTAlds need to be explicitly considered in environmental, toxicological, and waste treatment investigations. The results of the current study will facilitate a more complete examination of the environmental fate of PFAlds and FTAlds. PMID:26980678

    The present work studied the uptake of 8:2 perfluoroalkyl phosphate diester (diPAP) by two different crops (lettuce and carrot) and two different amended soils. Firstly, the possible degradation of 8:2 diPAP in the absence of crop was studied and 8:2 monoPAP (monophosphate), 8:2 FTCA (saturated fluorotelomer carboxylate), 8:2 FTUCA (unsaturated fluorotelomer carboxylate), 7:3 FTCA (saturated fluorotelomer carboxylate), PFHpA (perfluoroheptanoic acid), PFHxA (perfluorohexanoic acid) and PFOA (perfluorooctanoic acid) were detected. In the presence of crops, different degradation products were detected in the soil and, while PFNA (perfluorononanoic acid), PFHpA, PFHxA, PFPeA (perfluoropentacoic acid), PFBA (perfluorobutanoic acid), 7:3 FTCA and PFOA were determined in the cultivation media when carrot was grown, PFOA was the only degradation product detected in the case of lettuce experiments. Regarding the uptake in carrot, all the degradation products except 7:3 FTCA were translocated from the soil to the carrot. Carrot core, peel and leaves bioconcentration factors, BCFs, were determined for 8:2 diPAP and its degradation products. Values lower than method detection limits for core and low BCFs in peel (0.025-0.042) and leaves (0.028-0.049) were achieved for 8:2 diPAP. Regarding to the degradation products, the higher their water solubility, the higher the plant translocation. In this sense, the lower the carbon chain length of PFCAs, the higher the BCFs determined (PFBA > PFHxA > PFHpA > PFOA > PFNA). In general, lower total BCFs were achieved when the total organic carbon of the soils increased. For lettuce experiments, 8:2 diPAP (0.04-0.18) and PFOA (0.28-1.57) were only determined in lettuce heart. PMID:26991379

    There are important measurements of alcoholism that are poorly understood by physicians. Professional attitudes toward alcoholic patients are often counterproductive. Americans spend about $30 billion on alcohol a year and most adults drink alcohol. Even though traditional criteria allow for recognition of the disease, diagnosis is often made late in the natural course, when intervention fails. Alcoholism is a major health problem and accounts for 10 percent of total health care costs. Still, this country's 10 million adult alcoholics come from a pool of heavy drinkers with well defined demographic characteristics. These social, cultural and familial traits, along with subtle signs of addiction, allow for earlier diagnosis. Although these factors alone do not establish a diagnosis of alcoholism, they should alert a physician that significant disease may be imminent. Focus must be directed to these aspects of alcoholism if containment of the problem is expected. PMID:685264

    The production of fluorinated compounds over the past 50 years has had numerous industrial applications. For example, perfluorinated carboxylic acids are used in the synthesis of polymers and fire retardants, perfluoroalkyl sulfonates act as surface protectors, and fluorotelomer alcohols are incorporated into products such as paints, coatings, polymers, and adhesives. Fluorotelomer alcohols (FTOHs) are linear polyfluorinated alcohols with the formula CF3(CF2)nCH2CH2OH (n=1,3,5,...). They have been suggested as possible precursors for perfluorinated carboxylic acids and detected in the troposphere over several North American sites. Perfluorocarboxylic acids have even been detected in the arctic food chain, human blood, tissues of animals and environmental waters. We report the surface activity of fluorotelomer alcohols and perfluorinated carboxylic acids at the air-water interface by using a Langmuir trough. Isotherms of the pure compounds along with mixed films with other organic carboxylic acids were collected. The main objective of these experiments was to understand their heterogeneous chemistry by characterizing the pure and mixed films, which serves as a representative model for organic films on atmospheric surfaces such as those found on oceans and aqueous aerosols. Film properties and behavior, notably stabilization, evaporation from the subphase, and miscibility in the single-component mixtures as well as in the mixed films will be discussed. An important consequence of FTOHs and perfluorocarboxylic acids being found to partition to the air-water interface is the possibility of their transport and widespread distribution and deposition using atmospheric aerosols.

    Perfluorooctane sulfonate (PFOS), a widely used mist suppressant in hard chrome electroplating industry, has been listed in the Stockholm Convention for global ban. 6:2 Fluorotelomer sulfonate (6:2 FTS) acid and salts have been adopted as alternative products in the market, but no data about their abiotic degradation has been reported. In the present study, the degradability of 6:2 FTS potassium salt (6:2 FTS-K) was evaluated under various advanced oxidation processes, including ultraviolet (UV) irradiation, UV with hydrogen peroxide (H2O2), alkaline ozonation (O3, pH = 11), peroxone (O3/H2O2), and Fenton reagent oxidation (Fe(2+)/H2O2). UV/H2O2 was found to be the most effective approach, where the degradation of 6:2 FTS-K followed the pseudo-first-order kinetics. The intermediates were mainly shorter chain perfluoroalkyl carboxylic acid (C7 to C2), while sulfate (SO4 (2-)) and fluoride (F(-)) were found to be the final products. The high yields of SO4 (2-) and F(-) indicate that 6:2 FTS-K can be nearly completely desulfonated and defluorinated under UV/H2O2 condition. The degradation should firstly begin with the substitution of hydrogen atom by hydroxyl radicals, followed by desulfonation, carboxylation, and sequential "flake off" of CF2 unit. Compared with PFOS which is inert in most advanced oxidation processes, 6:2 FTS-K is more degradable as the alternative.

    In light of the widespread presence of perfluorooctanoic acid (PFOA) in the environment, a comprehensive laboratory-scale study has developed data requested by the U.S. Environmental Protection Agency (EPA) to determine whether municipal and/or medical waste incineration of commercial fluorotelomer-based polymers (FTBPs) at end of life is a potential source of PFOA that may contribute to environmental and human exposures. The study was divided into two phases (I and II) and conducted in accordance with EPA Good Laboratory Practices (GLPs) as described in the quality assurance project plan (QAPP) for each phase. Phase I testing determined that the PFOA transport efficiency across the thermal reactor system to be used in Phase II was greater than 90%. Operating at 1000°C over 2s residence time with 3.2-6.6mgdscm(-1) hydrogen fluoride (HF), corrected to 7% oxygen (O2), and continuously monitored exhaust oxygen of 13%, Phase II testing of the FTBP composites in this thermal reactor system yielded results demonstrating that waste incineration of fluorotelomer-based polymers does not result in the formation of detectable levels of PFOA under conditions representative of typical municipal waste combustor (MWC) and medical waste incinerator (MWI) operations in the U.S. Therefore, waste incineration of these polymers is not expected to be a source of PFOA in the environment.

  20. Biotransformation of 6:2 fluorotelomer alcohol (6:2 FTOH) by a wood-rotting fungus.

    2014-04-01

    Biotransformation of 6:2 FTOH [F(CF2)6CH2CH2OH] by the white-rot fungus, Phanerochaete chrysosporium, was investigated in laboratory studies. 6:2 FTOH is a raw material increasingly being used to replace products that can lead to long-chain perfluoroalkyl carboxylic acids (PFCAs, ≥ 8 carbons). During a product's life cycle and after final disposal, 6:2 FTOH-derived compounds may be released into the environment and potentially biotransformed. In this study, P. chrysosporium transformed 6:2 FTOH to perfluorocarboxylic acids (PFCAs), polyfluorocarboxylic acids, and transient intermediates within 28 days. 5:3 Acid [F(CF2)5CH2CH2COOH] was the most abundant transformation product, accounting for 32-43 mol % of initially applied 6:2 FTOH in cultures supplemented with lignocellulosic powder, yeast extract, cellulose, and glucose. PFCAs, including perfluoropentanoic (PFPeA) and perfluorohexanoic (PFHxA) acids, accounted for 5.9 mol % after 28-day incubation. Furthermore, four new transformation products as 6:2 FTOH conjugates or 5:3 acid analogues were structurally confirmed. These results demonstrate that P. chrysosporium has the necessary biochemical mechanisms to drive 6:2 FTOH biotransformation pathways toward more degradable polyfluoroalkylcarboxylic acids, such as 5:3 acid, with lower PFCA yields compared to aerobic soil, sludge, and microbial consortia. Since bacteria and fungi appear to contribute differently toward the environmental loading of FTOH-derived PFCAs and polyfluorocarboxylic acids, wood-rotting fungi should be evaluated as potential candidates for the bioremediation of wastewater and groundwater contaminated with fluoroalkyl substances.

    The aerobic biodegradation of [1,2-(14)C] 6:2 FTOH [F(CF(2))(6)(14)CH(2)(14)CH(2)OH] in a flow-through soil incubation system is described. Soil samples dosed with [1,2-(14)C] 6:2 FTOH were analyzed by liquid scintillation counting, LC/ARC (liquid chromatography/accurate radioisotope counting), LC/MS/MS, and thermal combustion to account for 6:2 FTOH and its transformation products over 84 d. Half of the [1,2-(14)C] 6:2 FTOH disappeared from soil in 1.3 d, undergoing simultaneous microbial degradation and partitioning of volatile transformation product(s) and the 6:2 FTOH precursor into the air phase. The overall (14)C (radioactivity) mass balance in live and sterile treatments was 77-87% over 84-d incubation. In the live test system, 36% of total (14)C dosed was captured in the airflow (headspace), 25% as soil-bound residues recovered via thermal combustion, and 16% as soil extractable. After 84 d, [(14)C] 5:2 sFTOH [F(CF(2))(5)CH(OH)(14)CH(3)] was the dominant transformation product with 16% molar yield and primarily detected in the airflow. The airflow also contained [1,2-(14)C] 6:2 FTOH and (14)CO(2) at 14% and 6% of total (14)C dosed, respectively. The other significant stable transformation products, all detected in soil, were 5:3 acid [F(CF(2))(5)CH(2)CH(2)COOH, 12%], PFHxA [F(CF(2))(5)COOH, 4.5%] and PFPeA [F(CF(2))(4)COOH, 4.2%]. Soil-bound residues as well as conjugates between fluorinated transformation products and dissolved soil components were only observed in the live test system and absent in the sterile soil, suggesting that such binding and complexation are microbially or enzymatically driven processes. At day 84, 5:3 acid is postulated to be the major transformation product in soil-bound residues, which may not be available for further biodegradation in soil environment.

    2014-06-01

    Sardinian alcohol-preferring (sP) rats have been selectively bred for high alcohol preference and consumption. When exposed to the standard, home cage 2-bottle "alcohol (10%, v/v) vs. water" choice regimen with continuous access, male sP rats consume daily approximately 6 g/kg alcohol. Conversely, when exposed to the intermittent (once every other day) access to 2 bottles containing alcohol (20%, v/v) and water, respectively, male sP rats display marked increases in daily alcohol intake and signs of alcohol intoxication and "behavioral" dependence. The present study was designed to assess alcohol intake in female sP rats exposed, under the 2-bottle choice regimen, to (a) 10% (v/v) alcohol with continuous access (CA10%), (b) 10% (v/v) alcohol with intermittent access (IA10%), (c) 20% (v/v) alcohol with continuous access (CA20%), and (d) 20% (v/v) alcohol with intermittent access (IA20%). Male sP rats (exposed to CA10% and IA20% conditions) were included for comparison. Over 20 daily drinking sessions, daily alcohol intake in female CA10% and IA20% rats averaged 7.0 and 9.6 g/kg, respectively. The rank of alcohol intake was IA20% > IA10% = CA20% > CA10%. Conversely, daily alcohol intake in male CA10% and IA20% rats averaged 6.0 and 8.2 g/kg, respectively. Comparison of female and male rats yielded the following rank of alcohol intake: female IA20% > male IA20% > female CA10% ≥ male CA10%. An additional experiment found that alcohol drinking during the first hour of the drinking session produced mean blood alcohol levels of 35-40 mg% and 85-100 mg% in the CA10% and IA20% rats, respectively. These results (a) extend to female sP rats previous data demonstrating the capacity of the IA20% condition to markedly escalate alcohol drinking, and (b) demonstrate that female sP rats consume more alcohol than male sP rats. This sex difference is more evident under the IA20% condition, suggesting that female sP rats are highly sensitive to the promoting effect

    PFOA (perfluorooctanoic acid) oxidation (0.121-6.04 μM) by heat-activated persulfate was evaluated at 20-60 °C with 4.2-84 mM [Formula: see text] and in the presence of soluble fuel components to assess feasibility for in-situ remediation of groundwater. 6:2 fluorotelomer sulfonic acid/sulfonate (6:2 FTSA) and PFOS (perfluorooctanesulfonic acid) persulfate oxidation was also evaluated in a subset of conditions given their co-occurrence at many sites. High performance liquid chromatography electron spray tandem mass spectrometry was used for organic analysis and fluoride was measured using a fluoride-specific electrode. PFOA pseudo-1st order transformation rates (k1,PFOA) increased with increasing temperature (half-lives from 0.1 to 7 d for 60 to 30 °C) sequentially removing CF2 groups ('unzipping') to shorter chain perfluoroalkyl carboxylic acids (PFCAs) and F(-). At 50 °C, a 5-fold increase in [Formula: see text] led to a 5-fold increase in k1,PFOA after which self-scavenging by sulfate radicals decreased the relative rate of increase with more [Formula: see text] . Benzene, toluene, ethylbenzene and xylene did not affect k1,PFOA even at 40 times higher molar concentrations than PFOA. A modeling approach to explore pathways strongly supported that for 6:2 FTSA, both the ethyl linkage and CF2-CH2 bond of 6:2 FTSA oxidize simultaneously, resulting in a ratio of ∼25/75 PFHpA/PFHxA. The effectiveness of heat-activated [Formula: see text] on PFOA oxidation was reduced in a soil slurry; therefore, repeated persulfate injections are required to efficiently achieve complete oxidation in the field. However, PFOS remained unaltered even at higher activation temperatures, thus limiting the sole use of heat-activated persulfate for perfluoroalkyl substances removal in the field. PMID:26692515

  1. Endonucleolytic activity directed towards 8-(2-hydroxy-2-propyl) purines in double-stranded DNA.

    PubMed

    Livneh, Z; Elad, D; Sperling, J

    1979-11-01

    Photoalkylation of circular covalently closed DNA from phage PM2 with isopropyl alcohol by using a free radical photoinitiator and UV light of lambda greater than 305 nm led to the specific 8-substitution of purine moieties in the DNA, yielding 8-(2-hydroxy-2-propyl)adenine and 8-(2-hydroxy-2-propyl)guanine as the only detectable damage in the DNA. Using this specifically photoalkylated DNA as a substrate, we discovered in extracts of Micrococcus luteus an endonucleolytic activity that is directed towards 8-(2-hydroxy-2-propyl) purines in DNA. The activity is not a combination of a DNA-glycosylase and an apurinic site endonuclease. It is not inhibited by single-stranded DNA, by UV- or gamma-irradiated single-stranded DNA, or by normal or depurinated double-stranded DNA. however, gamma- or UV-(254 nm) irradiated double-stranded DNAs to inhibit the activity, hinting at the possibility of a common type of lesion in these damaged DNAs. Divalent cations are not required for the incising activity, and it is fully active in 1 mM EDTA, whereas caffeine and ATP cause inhibition. Extracts of mutant M. luteus lacking pyrimidine-dimer-directed endonucleases were found to contain the endonucleolytic activity in levels comparable to those present in the wild type. After the incision, we could demonstrate the specific excision of the 8-alkylated purines from the damaged DNA. The special conformational consequences of the 8-alkylation of purines, at the nucleotide level, namely their nonregular syn conformation, suggest that it is the distortion in the DNA that is recognized by the endonuclease.

  4. Did the 8.2 ka event affect southern Africa?

    NASA Astrophysics Data System (ADS)

    Shaw, Paul

    2014-05-01

    Palaeoenvironmental reconstruction of southern Africa over the past 4 decades has focused largely on the last glacial cycle, and, more recently, events during to Holocene, interpreted largely at the millennial scale. Little attention has been given to sub-millenial drivers and impacts, other than the Little Ice Age (HolmgreN et al 2001). The 8.2ka event has been recognized in Europe for over half a century from peat cores and dendrochronology. A Bond Event caused by disruption of the Gulf Stream by melting Laurentian ice, it lasted around 100 years and resulted in a fall in temperature in northern Europe of up to 6o C. Recently published high-resolution speleothem records have indicated significant short-term change over a much wider area than previously thought, including the Caribbean, eastern Brazil, Spain, Oman and China. A recent paper on Trinidad (Boyd et al, in press) emphasizes a period of prolonged drought in the southern Caribbean due to a southerly emplacement of the ITCZ. The question then arises whether this shift affected the southern hemisphere, and if so, what would be the likely impacts and evidence. A study of late Quaternary lake levels in Lake Chilwa, Malawi (Thomas et al 2009) noted a correspondence between high lake stands and Heinrich events, whilst modeling of Atlantic freshwater influx using the HadCM3 GCM indicates negative precipitation anomalies in the Caribbean and west Africa, with a significant positive anomaly in the interior of southern Africa, possibly linked to enhanced monsoonal activity in the Indian Ocean. These patterns in southern and western Africa have been suggested around 8.2 ka in a review of early Holocene data (Burrough & Thomas 2013), but the chronological resolution is not sufficient to conclude the observation. The only speleothem record for this period, T8 in Cold Air Cave, Makapansgat Valley (Holmgren et al 2003) shows an anomaly, but with temporal resolution at a 50 yr sampling interval, this again is speculative

  6. Alcohol Dehydrogenase from Methylobacterium organophilum

    1978-01-01

    The alcohol dehydrogenase from Methylobacterium organophilum, a facultative methane-oxidizing bacterium, has been purified to homogeneity as indicated by sodium dodecyl sulfate-gel electrophoresis. It has several properties in common with the alcohol dehydrogenases from other methylotrophic bacteria. The active enzyme is a dimeric protein, both subunits having molecular weights of about 62,000. The enzyme exhibits broad substrate specificity for primary alcohols and catalyzes the two-step oxidation of methanol to formate. The apparent Michaelis constants of the enzyme are 2.9 × 10−5 M for methanol and 8.2 × 10−5 M for formaldehyde. Activity of the purified enzyme is dependent on phenazine methosulfate. Certain characteristics of this enzyme distinguish it from the other alcohol dehydrogenases of other methylotrophic bacteria. Ammonia is not required for, but stimulates the activity of newly purified enzyme. An absolute dependence on ammonia develops after storage of the purified enzyme. Activity is not inhibited by phosphate. The fluorescence spectrum of the enzyme indicates that it and the cofactor associated with it may be chemically different from the alcohol dehydrogenases from other methylotrophic bacteria. The alcohol dehydrogenases of Hyphomicrobium WC-65, Pseudomonas methanica, Methylosinus trichosporium, and several facultative methylotrophs are serologically related to the enzyme purified in this study. The enzymes of Rhodopseudomonas acidophila and of organisms of the Methylococcus group did not cross-react with the antiserum prepared against the alcohol dehydrogenase of M. organophilum.

Regular science observations have just started with the first of these giant telescopes, while impressive astronomical images are being obtained with the second. The work is hard, but the mood in the control room is good. Insiders claim that there have even been occasions on which the groups have had a friendly "competition" about which telescope makes the "best" images! The ANTU-team has worked with the FORS multi-mode instrument , their colleagues at KUEYEN use the VLT Test Camera for the ongoing tests of this new telescope. While the first is a highly developed astronomical instrument with a large-field CCD imager (6.8 x 6.8 arcmin 2 in the normal mode; 3.4 x 3.4 arcmin 2 in the high-resolution mode), the other is a less complex CCD camera with a smaller field (1.5 x 1.5 arcmin 2 ), suited to verify the optical performance of the telescope. As these images demonstrate, the performance of the second VLT Unit Telescope is steadily improving and it may not be too long before its optical quality will approach that of the first.

    The Diagnostic Interview Schedule was employed to ascertain the prevalence of major depressive disorder (MDD), alcohol and substance abuse in a sample of 424 college students aged 16 to 19 years. Applying DSM III criteria, the prevalence of MDD was 6.8 per cent; of alcohol abuse, 8.2 per cent; and of substance abuse 9.4 per cent. Alcohol abuse was associated with MDD, but not with other psychiatric diagnoses. Substance abuse was associated both with MDD and with other psychiatric diagnoses as well. The onset of MDD almost always preceded alcohol or substance abuse suggesting the possibility of self-medication as a factor in the development of alcohol or substance abuse. PMID:3492151

    A pair of homologous series of polyfluorinated degradation products have been identified, both having structures similar to perfluorocarboxylic acids but (i) having a H substitution for F on the α carbon for 2H polyfluorocarboxylic acids (2HPFCAs) and (ii) bearing a double bond between the α-β carbons for the unsaturated PFCAs (2uPFCAs). Obtaining an authentic sample containing 2uPFOA and 2HPFOA, we optimized a mass-spectrometric multiple-reaction-monitoring (MS/MS) technique and then identified uPFCA and HPFCA homologous series in sludge-applied agricultural soils and fodder grasses for cattle grazing. Analysis of samples from a degradation experiment of commercial fluorotelomer-based polymers (FTPs), the dominant product of the fluorotelomer industry, confirmed that commercial FTPs are a potential source of uPFCAs and HPFCAs to the environment. We further confirmed the identity of the uPFCAs by imposing high-energy ionization to decarboxylate the uPFCAs then focused on the fluorinated chains in the first MS quadrupole. We also employed this high-energy ionization to decarboxylate and analyze PFCAs by MS/MS (for the first time, to our knowledge). In exploratory efforts, we report the possible detection of unsaturated perfluorooctanesulfonate in environmental samples, having a conceptual double-bond structure analogous to uPFOA. Using microcosms spiked with fluorotelomer compounds, we found 2uPFOA and 2HPFOA to be generated from unsaturated 8:2 fluorotelomer acid (8:2 FTUCA) and propose β- and α-oxidation mechanisms for generation of these compounds from 8:2 FTUCA. In light of these experimental results, we also reexamined the proposed biodegradation pathways of 8:2 fluorotelomer alcohol.

    We have investigated the gas-phase chemistry in dense cores where ice mantles containing ethanol and other alcohols have been evaporated. Model calculations show that methanol, ethanol, propanol, and butanol drive a chemistry leading to the formation of several large ethers and esters. Of these molecules, methyl ethyl ether (CH3OC2H5) and diethyl ether (C2H5)2O attain the highest abundances and should be present in detectable quantities within cores rich in ethanol and methanol. Gas-phase reactions act to destroy evaporated ethanol and a low observed abundance of gas-phase C,H,OH does not rule out a high solid-phase abundance. Grain surface formation mechanisms and other possible gas-phase reactions driven by alcohols are discussed, as are observing strategies for the detection of these large interstellar molecules.

For data collection, it was used the Scale of Attitudes to alcohol, alcoholism and alcoholic, applied to 144 nursing students. The results showed a tendency to negative attitudes of these students in face of alcoholism, alcoholic person and alcoholic drinks, since most participants were placed in category indifferent or disagree with the positive items, agreeing with negative scale items. We conclude that this trend of negative attitudes is connected to insufficient attention given to the subject during the nurses' education, being verified the need for greater importance to be given to this problem.

    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 is widely consumed across the world in different cultural and social settings. Types of alcohol consumption differ between (a) light, only occasional consumption, (b) heavy chronic alcohol consumption, and (c) binge drinking as seen as a new pattern of alcohol consumption among teenagers and young adults. Heavy alcohol consumption is detrimental to many organs and tissues, including bones. Osteoporosis is regularly mentioned as a secondary consequence of alcoholism, and chronic alcohol abuse is established as an independent risk factor for osteoporosis. The review will present the different mechanisms and effects of alcohol intake on bone mass, bone metabolism, and bone strength, including alcoholism-related "life-style factors" such as malnutrition, lack of exercise, and hormonal changes as additional causative factors, which also contribute to the development of osteoporosis due to alcohol abuse.

    The effects of alcohol on induction of arrhythmias is dose-dependent, independent of preexisting cardiovascular diseases or heart failure and can affect otherwise healthy subjects. While the probability of atrial fibrillation increases with the alcohol dosage, events of sudden cardiac death are less frequent with low and moderate consumption but occur more often in heavy drinkers with alcoholic cardiomyopathy. Men are first affected at higher dosages of alcohol but women can suffer from arrhythmias at lower dosages. Thromboembolisms and ischemic stroke can occur less often at lower dosages of alcohol; however, hemorrhagic stroke and subarachnoid hemorrhage are increased with higher alcohol dosages. Recognizable protective mechanisms of alcohol with respect to cardiovascular diseases only occur with lower amounts of alcohol of less than 10 g per day. Underlying mechanisms explain these controversial effects. Specific therapeutic options for alcohol-related arrhythmias apart from abstinence from alcohol consumption are not known. PMID:27582366

    Ethanol is an alcohol made from grain that can be blended with gasoline to extend petroleum supplies and to increase gasoline octane levels. Congressional proposals to encourage greater use of alternative fuels could increase the demand for ethanol. This report evaluates the growth potential of the ethanol industry to meet future demand increases and the impacts increased production would have on American agriculture and the federal budget. It is found that ethanol production could double or triple in the next eight years, and that American farmers could provide the corn for this production increase. While corn growers would benefit, other agricultural segments would not; soybean producers, for example could suffer for increased corn oil production (an ethanol byproduct) and cattle ranchers would be faced with higher feed costs because of higher corn prices. Poultry farmers might benefit from lower priced feed. Overall, net farm cash income should increase, and consumers would see slightly higher food prices. Federal budget impacts would include a reduction in federal farm program outlays by an annual average of between $930 million (for double current production of ethanol) to $1.421 billion (for triple production) during the eight-year growth period. However, due to an partial tax exemption for ethanol blended fuels, federal fuel tax revenues could decrease by between $442 million and $813 million.

  8. Alcoholic hepatitis.

    Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (< 84 days after diagnosis), patients with AH were likely to die from liver-related events and infections. In the long-term (≥ 84 days after diagnosis), those who developed cirrhosis mainly died from liver-related causes, and

    Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

    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.

    The 8.2ky event is attributed to pronounced cooling associated with the last stages of the deglaciation of the Laurentide and Scandinavian ice sheets. The global extent of this event is not well known, but it has recently been documented in various archives even in the southern hemisphere. We present proxy data evidence from speleothems collected in Venezuela and Puerto Rico that grew during the 8.2ky event. The age models based on precise MC-ICPMS 230Th/U-dating indicate that all stalagmites grew approximately 15 cm during the event - much faster than during any other growth period. This suggests that the 8.2ky event was associated with higher than normal precipitation throughout the eastern Caribbean. Higher precipitation values could have increased lowland flooding along the coastal areas of northern South America, already affected by early Holocene sea-level change, and might be linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. The eastern Caribbean seems to be very sensitive to the changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC). During the 8.2ky event, moisture transfer to the northern latitudes may have been slower resulting in the observed low-latitude precipitation patterns.

    Alcoholism, a worldwide disorder, is the cause of a variety of neurologic disorders. In this article we discuss the cellular pathophysiology of ethanol addition and abuse as well as evidence supporting and refuting the role of inheritance in alcoholism. A genetic marker for alcoholism has not been identified, but neurophysiologic studies may be promising. Some neurologic disorders related to longterm alcoholism are due predominantly to inadequate nutrition (the thiamine deficiency that causes Wernicke's encephalopathy), but others appear to involve the neurotoxicity of ethanol on brain (alcohol withdrawal syndrome and dementia) and peripheral nerves (alcoholic neuropathy and myopathy).

    Prenatal exposure to alcohol can damage the developing fetus and is the leading preventable cause of birth defects and intellectual and neurodevelopmental disabilities. In 1973, fetal alcohol syndrome was first described as a specific cluster of birth defects resulting from alcohol exposure in utero. Subsequently, research unequivocally revealed that prenatal alcohol exposure causes a broad range of adverse developmental effects. Fetal alcohol spectrum disorder (FASD) is the general term that encompasses the range of adverse effects associated with prenatal alcohol exposure. The diagnostic criteria for fetal alcohol syndrome are specific, and comprehensive efforts are ongoing to establish definitive criteria for diagnosing the other FASDs. A large and growing body of research has led to evidence-based FASD education of professionals and the public, broader prevention initiatives, and recommended treatment approaches based on the following premises:▪ Alcohol-related birth defects and developmental disabilities are completely preventable when pregnant women abstain from alcohol use.▪ Neurocognitive and behavioral problems resulting from prenatal alcohol exposure are lifelong.▪ Early recognition, diagnosis, and therapy for any condition along the FASD continuum can result in improved outcomes.▪ During pregnancy:◦no amount of alcohol intake should be considered safe;◦there is no safe trimester to drink alcohol;◦all forms of alcohol, such as beer, wine, and liquor, pose similar risk; and◦binge drinking poses dose-related risk to the developing fetus.

Our current knowledge of the neuroscience of alcohol dependence has evolved from the interchange of information gathered from both human alcoholics and animal models of alcoholism. Together, studies in humans and animal models have provided support for the involvement of specific brain structures over the course of alcohol addiction, including the prefrontal cortex, basal ganglia, cerebellum, amygdala, hippocampus, and the hypothalamic–pituitary–adrenal axis.

    The 8.2 ka event was the last deglacial abrupt climate event. A reduction in the Atlantic meridional overturning circulation (AMOC) attributed to the drainage of glacial Lake Agassiz may have caused the event, but the freshwater signature of Lake Agassiz discharge has yet to be identified in (delta)18O of foraminiferal calcite records from the Labrador Sea, calling into question the connection between freshwater discharge to the North Atlantic and AMOC strength. Using Mg/Ca-paleothermometry, we demonstrate that approx. 3 C of near-surface ocean cooling masked an 1.0 % decrease in western Labrador Sea (delta)18O of seawater concurrent with Lake Agassiz drainage. Comparison with North Atlantic (delta)18O of seawater records shows that the freshwater discharge was transported to regions of deep-water formation where it could perturb AMOC and force the 8.2 ka event.

    We present data from speleothems collected in Venezuela and Puerto Rico showing that the eastern Caribbean was anomalously moist during the 8.2ka event. Evidence from high-resolution analyses of Greenland ice core (GISP2) shows that at the same time northern Europe and the north Atlantic were cooler by 3 - 6° C. The trigger for the 8.2ka event is thought to be pulsed meltwater discharges from a multi-event drainage of proglacial lakes associated with the decaying Laurentide Ice Sheet margin. The meltwater apparently slowed the thermohaline circulation decreasing warmth to northern Europe. At the same time moisture transfer to the northern latitudes may have slowed resulting in the observed lower latitude precipitation patterns. The eastern Caribbean seems to be especially sensitive to the changes in the strength of the Atlantic meridional overturning circulation (AMOC). Higher precipitation values may also have increased lowland flooding along the coastal areas of north eastern South America, already affected by early Holocene sea-level change, and are linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. Our age models based on precise MC-ICPMS 230Th/U-dating indicate that the eastern Caribbean stalagmites all grew at about the same rate of 15 cm through the 8.2 ka event, much faster than during any other growth period, except today when they are also growing at an accelerated rate.

    MELCOR is a fully integrated, engineering-level computer code, being developed at Sandia National Laboratories for the USNRC. This code models the entire spectrum of severe accident phenomena in a unified framework for both BWRs and PWRs. As part of an ongoing assessment program, the MELCOR computer code has been used to analyze a station blackout transient in Surry, a three-loop Westinghouse PWR. Basecase results obtained with MELCOR 1.8.2 are presented, and compared to earlier results for the same transient calculated using MELCOR 1.8.1. The effects of new models added in MELCOR 1.8.2 (in particular, hydrodynamic interfacial momentum exchange, core debris radial relocation and core material eutectics, CORSOR-Booth fission product release, high-pressure melt ejection and direct containment heating) are investigated individually in sensitivity studies. The progress in reducing numeric effects in MELCOR 1.8.2, compared to MELCOR 1.8.1, is evaluated in both machine-dependency and time-step studies; some remaining sources of numeric dependencies (valve cycling, material relocation and hydrogen burn) are identified.

    Moderate drinking for the elderly of both genders is no more than one drink per day, where a drink is defined as 12 oz of beer, 5 oz of wine, or 1.5 oz of spirits. Age does not affect the rate of absorption or elimination of alcohol. Lean body mass decreases and adipose tissue increases with age, however, resulting in a corresponding decrease in the volume of total body water. With a smaller volume of distribution, an alcohol dose identical to that administered to a younger individual of the same size and gender will produce a higher blood alcohol concentration in the elderly. Low-dose alcohol stimulates appetite and promoters regular bowel function. In the well-nourished nonalcoholic elderly, the negative impact of alcohol consumption on nutrition is minimal. Alcohol consumption improves mood by increasing feelings of happiness and freedom from care while lessening inhibitions, stress, tension, and depression. Although in the laboratory low-dose alcohol improves certain types of cognitive function in young men, in other types of task performance, alcohol induces impairment, which worsens with age. The effects of alcohol on sleep are primarily detrimental, worsening both insomnia and breathing disturbances during sleep. Although the role of alcohol consumption in mortality from heart disease has not been investigated in the elderly, moderate drinking appears safe. Under some circumstances low-dose alcohol may produce analgesia whereas in others it may worsen pain. The elderly use a significant proportion of both prescription and over-the-counter medication, a large variety of which interact with alcohol. Alcoholic beverage consumption may exacerbate cognitive impairment and dementias of other etiology. Although some studies suggest that moderate use of alcohol by institutionalized senior citizens appears to produce benefits including improved socialization, separation of the effects of the social situation from those specifically attributable to alcohol remains to

    Alcohol abuse is a significant contributor to the global burden of disease and can lead to tissue damage and organ dysfunction in a subset of alcoholics. However, a subset of alcoholics without any of these predisposing factors can develop alcohol-mediated organ injury. The gastrointestinal tract (GI) could be an important source of inflammation in alcohol-mediated organ damage. The purpose of review was to evaluate mechanisms of alcohol-induced endotoxemia (including dysbiosis and gut leakiness), and highlight the predisposing factors for alcohol-induced dysbiosis and gut leakiness to endotoxins. Barriers, including immunologic, physical, and biochemical can regulate the passage of toxins into the portal and systemic circulation. In addition, a host of environmental interactions including those influenced by circadian rhythms can impact alcohol-induced organ pathology. There appears to be a role for therapeutic measures to mitigate alcohol-induced organ damage by normalizing intestinal dysbiosis and/or improving intestinal barrier integrity. Ultimately, the inflammatory process that drives progression into organ damage from alcohol appears to be multifactorial. Understanding the role of the intestine in the pathogenesis of alcoholic liver disease can pose further avenues for pathogenic and treatment approaches.

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

    This paper is based upon the “Charles Lieber Satellite Symposia” organized by Manuela G. Neuman at the Research Society on Alcoholism (RSA) Annual Meetings, 2013 and 2014. The present review includes pre-clinical, translational and clinical research that characterize alcoholic liver disease (ALD) and non-alcoholic steatohepatitis (NASH). In addition, a literature search in the discussed area was performed. Strong clinical and experimental evidence lead to recognition of the key toxic role of alcohol in the pathogenesis of ALD. The liver biopsy can confirm the etiology of NASH or alcoholic steatohepatitis (ASH) and assess structural alterations of cells, their organelles, as well as inflammatory activity. Three histological stages of ALD are simple steatosis, ASH, and chronic hepatitis with hepatic fibrosis or cirrhosis. These latter stages may also be associated with a number of cellular and histological changes, including the presence of Mallory's hyaline, megamitochondria, or perivenular and perisinusoidal fibrosis. Genetic polymorphisms of ethanol metabolizing enzymes such as cytochrome p450 (CYP) 2E1 activation may change the severity of ASH and NASH. Alcohol mediated hepatocarcinogenesis, immune response to alcohol in ASH, as well as the role of other risk factors such as its comorbidities with chronic viral hepatitis in the presence or absence of human deficiency virus are discussed. Dysregulation of hepatic methylation, as result of ethanol exposure, in hepatocytes transfected with hepatitis C virus (HCV), illustrates an impaired interferon signaling. The hepatotoxic effects of ethanol undermine the contribution of malnutrition to the liver injury. Dietary interventions such as micro and macronutrients, as well as changes to the microbiota are suggested. The clinical aspects of NASH, as part of metabolic syndrome in the aging population, are offered. The integrative symposia investigate different aspects of alcohol-induced liver damage and possible

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

    The 8.2 ka event is a key test case for simulating the coupled climate response to changes in the Atlantic Meridional Overturning Circulation (AMOC). Most previous model experiments of this event were forced by the drainage of proglacial Lake Agassiz-Ojibway into the Hudson Bay and entering the Atlantic Ocean through the Hudson Strait. This drainage contained enough water to raise global sea level about 0.2 meters or more, but it likely had a short duration on the order of one year. Recent advances in quantifying the meltwater forcing associated with the 8.2 ka event point towards a forcing larger than the drainage of Lake Agassiz-Ojibway, probably involving the collapse of the Hudson Bay ice dome and raising global sea level on the order of 1.5 to 3.0 meters. Using the Community Climate System Model version 3 (CCSM3), we show that this larger forcing yields a better match to paleoclimate proxy records. Despite these improvements in forcing magnitude in model simulations, the forcing itself is still generally applied in an unrealistic geographic manner, across most of the Labrador Sea rather than only along the Labrador coast. We present additional experiments using the CCSM3, with an ocean model resolution only slightly coarser than that used in previous eddy-resolving simulations, to test the sensitivity to freshwater forcing location. When revised freshwater forcing is applied across the Labrador Sea, the AMOC is reduced by about 40% and climate anomalies compare well with proxy records of the 8.2 ka event in terms of magnitude and duration. When the forcing is added only along the Labrador coast, however, most meltwater joins the subtropical gyre and travels to the subtropics with minor impact to the AMOC (about 10% decrease). It is likely that model biases in the placement of the North Atlantic Current remain an important limitation for correctly simulating the 8.2 ka event, though the effects of icebergs or alternative freshwater sources cannot be completely

    Long-duration gamma-ray bursts (GRBs) are thought to result from the explosions of certain massive stars, and some are bright enough that they should be observable out to redshifts of z > 20 using current technology. Hitherto, the highest redshift measured for any object was z = 6.96, for a Lyman-alpha emitting galaxy. Here we report that GRB 090423 lies at a redshift of z approximately 8.2, implying that massive stars were being produced and dying as GRBs approximately 630 Myr after the Big Bang. The burst also pinpoints the location of its host galaxy.

    The role alcohol abuse plays in criminality has been a matter of primary concern for scholars for decades, as indicated by numerous studies and research projects. Most of these studies focus on determining the presence of a relationship between criminal behaviour and alcohol use, and whether criminal inclinations increase with the consumption of alcohol. Research shows that alcohol use indeed increases the risk of criminal behaviour, and that there is an especially strong and consistent correlation between alcohol abuse and violent crimes. However, researchers still disagree on the exact extent to which alcohol use effects criminality, and on the mechanisms causing alcohol to induce violent behaviour. A significant proportion of studies have focused in recent years on aggressive behaviour as a result of drinking alcohol. One of the most important means of measurement is the study of violent behaviour in places where alcohol is on sale. Studying the forms and frequency of violence in pubs and near off-licence stores greatly enables experts to understand the general context of the problem. This is the reason for the increasing interest in the topic throughout the past few decades. The present study focuses mainly on the literature published in English and German in leading journals of criminology since 1980, as well as on the most recent and fundamental publications on the topic, with special regard to results concerning drinking habits, and the relationship between drinking alcohol and violent or criminal behaviour, respectively.

    Background The objective of this study was to establish baseline data on alcohol consumption patterns, behaviours and harms among amateur sportsmen in the Republic of Ireland. Findings The study presents findings from the baseline survey for a cluster randomised controlled trial to evaluate the effectiveness of a community intervention programme to reduce problem alcohol use among a representative sample of Gaelic Athletic Association (GAA) clubs in two counties in the Republic of Ireland. Self reported alcohol use, prevalence of binge drinking, AUDIT scores and alcohol-related harms were assessed in amateur GAA sportsmen aged 16 years and over. Nine hundred and sixty (960) players completed questionnaires (72% response rate). Mean age was 24.0 years (S.D. 5.2). Of those aged 18 years or over, 75% had post-primary education; most (864, 90%) were current drinkers and 8.2% were regular smokers. The self-reported average yearly alcohol consumption was 12.5 litres. Almost one third (31%) of current drinkers reported drinking over the recommended limit of 21 standard drinks per week and just over half (54.3%) reported drinking 6 or more standard drinks in a row at least once a week (regular binge drinking). Of those who (self) completed the Alcohol Use Disorder Identification Test (AUDIT) questionnaire, three-quarters (74.7%) had a score of 8 or more; 11.5% had a score of 20 or above warranting referral for diagnostic evaluation and treatment. Almost all (87.6%) of the 864 drinkers reported experiencing at least one harm due to their drinking. These alcohol misuse outcomes were higher than those found in a nationally representative sample of males of a similar age. There were strong associations between regular binge drinking and reporting harms such as being in a fight (adjusted odds ratio (OR) 2.02, p < 0.001), missing time from work or college (adjusted OR 1.39, p = 0.04) or being in an accident (adjusted OR 1.78, p = 0.04).

    The collapse of the proglacial lakes Agassiz and Ojibway and the discharge of the lake water into the Hudson Bay were identified as the cause of the cold event occurred around 8.2 thousand years before present day (8.2kybp). This event has been widely studied using coupled climate models by adding freshwater forcing into the subpolar North Atlantic. However, results from the coarse resolution coupled models differ from that of a high resolution forced standalone ocean model simulation. Here we use a state-of-art fully coupled high-resolution climate model with 1/10 degree horizontal resolution for the ocean and sea ice, and ¼ degree for the atmosphere and land components to study the influence of the freshwater forcing to the Atlantic Meridional Overturning Circulation (AMOC). In this simulation, 2 Sv freshwater is added into the North Atlantic along a narrow band of west Baffin Bay to North of Labrador Sea for two years, then the freshwater forcing is switched off. Our preliminary results show that AMOC weakens by over 30% within the first 10 years, and recovers afterwards. The added freshwater were partly transported into the subpolar North Atlantic and partly into the subtropical gyre. The latter part was carried by Gulf Stream into the subpolar North Atlantic about 25 years later.

    Several arguments are in favour of the use of antidepressant drugs in alcohol-dependent patients, especially those acting on the serotoninergic system: (1) neurochemical data indicate the interaction between alcohol and 5-HT metabolism, (2) pharmacological studies show an improvement in the behaviour of alcoholized animals treated with antidepressants, (3) depression is a frequent disease in alcoholic patients. Tianeptine has been shown to be active in the treatment of depression in patients with history of alcohol abuse or dependence. In a first double-blind study performed versus amitryptiline, depression after withdrawal was improved by tianeptine, and biological abnormalities usually related to chronic alcohol intake tended to decrease. Similar results were found in an open study carried out on 277 alcoholic patients treated for 1 year. As these patients were depressed, no definite conclusion could be drawn from these results in respect of a specific action of tianeptine on alcohol dependence. Thus, a multicentre double-blind study has been performed which compared tianeptine (12.5 mg t.i.d) and placebo in 342 non-depressed patients fulfilling DSM-III-R criteria for Psychoactive Substance Dependence (alcohol). Other inclusion criteria were: daily alcohol intake higher than 80 g, minimum score of 3 on the Short-Mast Questionnaire, mean corpuscular volume above 98 fl and/or gamma Gt more than twice the upper limit of normal. The patients were treated for 9 months. The intention-to-treat population and the per protocol population were made up of 327 patients and 111 patients, respectively. The main efficacy criterion was the absence of alcoholic relapse (abstinence) defined by the patient's statements, the investigators clinical judgement and some biological parameters: alcohol blood levels, gamma Gt levels. Secondary criteria were the evolution of the alcohol consumption in the patients who relapsed, cumulative abstinence duration, a visual analogue scale for the

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

    Alcoholic liver disease is one of the most prevalent liver diseases worldwide, and a major cause of morbidity and mortality. Alcoholic hepatitis is a severe form of liver injury in patients with alcohol abuse, can present as an acute on chronic liver failure associated with a rapid decline in liver synthetic function, and consequent increase in mortality. Despite therapy, about 30%-50% of patients with severe alcoholic hepatitis eventually die. The pathogenic pathways that lead to the development of alcoholic hepatitis are complex and involve oxidative stress, gut dysbiosis, and dysregulation of the innate and adaptive immune system with injury to the parenchymal cells and activation of hepatic stellate cells. As accepted treatment approaches are currently limited, a better understanding of the pathophysiology would be required to generate new approaches that improve outcomes. This review focuses on recent advances in the diagnosis, pathogenesis of alcoholic hepatitis and novel treatment strategies.

The ALD spectrum includes alcoholic fatty liver, alcoholic hepatitis, cirrhosis, and the development of hepatocellular carcinoma. The diagnosis of ALD is based on a combination of clinical features, including a history of significant alcohol intake, evidence of liver disease, and laboratory findings. Abstinence is the most important treatment for ALD and the treatment plan varies according to the stage of the disease. Various treatments including abstinence, nutritional therapy, pharmacological therapy, psychotherapy, and surgery are currently available. For severe alcoholic hepatitis, corticosteroid or pentoxifylline are recommended based on the guidelines. In addition, new therapeutic targets are being under investigation. PMID:25278689

    Diagnosis of alcoholism is very important, given its high prevalence and possibility of influencing the disease course. For this reason, the so-called biological markers of alcoholism are useful. These are analytic parameters that alter in the presence of excessive alcohol consumption. The two most relevant markers are the gamma-glutamyltranspeptidase and carbohydrate deficient transferrin. With this clinical comment, we aim to contribute to the knowledge of these tests and promote its use in the clinical practice. PMID:16194480

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

    The topic 'alcohol and crime' has several aspects. This article shows how drug administration is based on a complex network of legal provisions and is enforced by criminal law sanctions. As to crimes influenced by alcohol, drunken driving is by far the most important and best researched field. Next, the article turns to the role of alcohol with regard to severe common crimes such as murder or child abuse. Finally, the issue of drunkenness as a defence is raised and the treatment of alcoholics as a criminal law sanction discussed.

  15. Alcohol disrupts sleep homeostasis

    Alcohol is a potent somnogen and one of the most commonly used “over the counter” sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to understand how and where alcohol acts to affect sleep. We have conducted a series of experiments using two different species, rats and mice, as animal models, and a combination of multi-disciplinary experimental methodologies to examine and understand anatomical and cellular substrates mediating the effects of acute and chronic alcohol exposure on sleep-wakefulness. The results of our studies suggest that the sleep-promoting effects of alcohol may be mediated via alcohol’s action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Lesions of the BF cholinergic neurons or blockade of AD A1 receptors results in attenuation of alcohol-induced sleep promotion, suggesting that AD and BF cholinergic neurons are critical for sleep-promoting effects of alcohol.

    A microwave alcohol fuel sensor comprises a microwave oscillator, a microwave receiver, and a microwave transmission circuit connected to the oscillator and the receiver. The microwave transmission circuit comprises a dielectric substrate and, a strip line mounted on the substrate so that microwaves leak from the substrate to an alcohol gasoline fuel, and the microwaves attenuate by alcohol dielectric loss, whereby output voltage from the receiver corresponds to alcohol content rate. The dielectric substrate is formed tubular so that a constant amount of the fuel is fed the sensor.

    The aim of this research was to estimate the community prevalence of alcoholism and the potential risk factors that affect it in the Edirne provincial centre by using a scanning test. A cross-sectional study was carried out in the Edirne provincial centre. A sample population composed of 500 women and 200 men was selected randomly after the categorisation of the population according to ethnicity, age and sex. Through face-to-face interviews, data collection sheets, which were prepared to analyse potential factors affecting alcoholism frequency, were filled in by the sample population. The Michigan Alcoholism Scanning Test (MAST) was employed. According to MAST's normal grading, individuals with 5 or more points are evaluated as alcoholics. Accordingly, 8.2% of the sample population fit the definition of alcoholic. Alcoholism frequency was considerably higher in gypsies, the self-employed, smokers, and people with higher income. From logistic regression analysis alcoholism frequency was 12.4 times higher in men than in women, 3.2 times higher in gypsies than in others, 1.9 times higher in people who earned an income in the preceding week than in the unemployed, and 3.7 times higher in individuals who had smoked more than 100 cigarettes during their life or those who had smoked at least 1 cigarette for 3 months or for a longer period than in those who hadn't smoked any cigarettes. The prevalence of alcoholism in the Edirne provincial centre was similar to that in other countries in Europe. The most important finding was that alcohol consumption decreased in the unemployed, a finding that differs from that in other parts of the world. Gypsies, who differ in tradition, way of life, and job compared to the other strata of society, also suffered from higher alcohol consumption. This group usually consumed wine and generally did not eat while drinking.

    The earthquake nucleation process has been vigorously investigated based on geophysical observations, laboratory experiments, and theoretical studies; however, a general consensus has yet to be achieved. Here, we studied nucleation process for the 2014 Iquique, Chile Mw 8.2 megathrust earthquake located within the current North Chile seismic gap, by analyzing a long-term earthquake catalog constructed from a cross-correlation detector using continuous seismic data. Accelerations in seismicity, the amount of aseismic slip inferred from repeating earthquakes, and the background seismicity, accompanied by an increasing frequency of earthquake migrations, started around 270 days before the mainshock at locations up-dip of the largest coseismic slip patch. These signals indicate that repetitive sequences of fast and slow slip took place on the plate interface at a transition zone between fully locked and creeping portions. We interpret that these different sliding modes interacted with each other and promoted accelerated unlocking of the plate interface during the nucleation phase. PMID:27109362

  3. Did accelerated North American ice sheet melt contribute to the 8.2 ka cooling event ?

    The 8.2 ka event was an abrupt cooling of the Northern Hemisphere 8,200 years ago. It is an almost ideal case study to benchmark the sensitivity of climate models to freshening of the North Atlantic by ice sheet melt (Schmidt and LeGrande, 2005). The event is attributed to the outburst of North American proglacial lakes into the Labrador Sea, causing a slow-down in Atlantic overturning circulation and cooling of 1-2.5 °C around the N. Atlantic (Alley and Ágústsdóttir,2005). Climate models fail to simulate the ~150 year duration of the event when forced with a sudden (0.5 to 5 years) drainage of the lakes (Morrill et al., 2013a). This could be because of missing forcings. For example, the separation of ice sheet domes around the Hudson Bay is thought to have produced a pronounced acceleration in ice sheet melt through a saddle collapse mechanism around the time of the event (Gregoire et al., 2012). Here we investigate whether this century scale acceleration of melt contributed to the observed climatic perturbation, using the coupled Ocean-Atmosphere climate model HadCM3. We designed and ran a set of simulations with temporally variable ice melt scenarios based on a model of the North American ice sheet. The simulated magnitude and duration of the cold period is controlled by the duration and amount of freshwater introduced to the ocean. With a 100-200 year-long acceleration of ice melt up to a maximum of 0.61 Sv, we simulate 1-3 °C cooling in the North Atlantic and ~0.5-1 °C cooling in Continental Europe; which are similar in magnitude to the ~1-2 °C cooling estimated from records for these areas (Morrill et al., 2013b). Some of the observed features are however not reproduced in our experiments, such as the most pronounced cooling of ~6 °C observed in central Greenland (Alley and Ágústsdóttir, 2005). The results suggest that the ~150 year North Atlantic and European cooling could be caused by ~200 years of accelerated North American ice sheet melt. This

    The RELAP5 independent assessment project at Sandia National Laboratories is part of an overall effort funded by the NRC to determine the ability of various systems codes to predict the detailed thermal/hydraulic response of LWRs during accident and off-normal conditions. The RELAP5 code is being assessed at SNLA against test data from various integral and separate effects test facilities. As part of this assessment matrix, an intermediate break transient (L5-1) and a core uncovery transient (L8-2) performed at the LOFT facility have been analyzed. Transient calculations were done with both cycle 14 and cycle 18 of RELAP5/MOD1 and a comparison of the predictions was made. The results show that RELAP5/MOD1 did very well calculating the overall behavior for these intermediate break experiments, although there were a few quantitative disagreements.

    An 8.2-W GaAs FET amplifier with 38.6 + or - 0.5-dB gain over a 17.7-19.1-GHz frequency band has been developed. This amplifier combines the outputs of eight multistage amplifier modules utilizing a radial combiner. This state-of-the art power level has been achieved with AM/PM of less than 2 deg/dB. The third-order intermodulation products at 1-dB gain compression were 20 dBc, and variation in group delay over the frequency band was less than + or - 0.25 ns. Tests show that the amplifier is unconditionally stable and follows the graceful-degradation principle.

    The formation of perfluorooctanoate (PFOA) from 1H,1H,2H,2H-perfluorodecanol (8:2 FTOH) was studied for the first time in laboratory experiments with brackish water. The water samples were collected from the Baltic Sea, which is one of the largest brackish water areas in the world and is polluted with PFOA and other perfluorinated compounds. The formation of PFOA was studied in closed-bottle experiments at different water temperatures. As a reference experiment, a modified OECD 310 test was conducted with sludge from a wastewater treatment plant and with brackish water. The PFOA and 8:2 FTOH were concentrated from water samples by solid-phase extraction (SPE) and were analysed using liquid chromatography-mass spectrometry. The effect of oxygen concentration on the formation of PFOA was studied using surface water samples with high and low oxygen contents. Other experiments were performed with oxygen-rich surface water and oxygen-deficient bottom water. The formation of PFOA was observed in all experiments; it was higher in the trial performed with brackish water than in the reference test carried out with sludge. Clear temperature dependence was observed in the formation of PFOA in brackish water tests; after a 30-day test period, a sixfold increase was observed in the amount of PFOA in surface water between the temperatures of 15 and 20 °C. Microbes were suggested as the major cause of the formation of PFOA, but other environmental characteristics, such as oxygen, could also affect the formation potential of PFOA. PMID:23881592

  8. Hunter-Gatherer Responses to the 8.2 Ka Cold Event in the Fennoscandian Arctic

    2014-12-01

    Because of a marked influence of warm Atlantic water to primary productivity in the Barents Sea, the marine ecosystem in northernmost Fennoscandia is sensitive to disturbances in the North Atlantic oceanographic system. The 8.2 ka climate event, according to current knowledge, was triggered by a disturbance in the North Atlantic Thermohaline circulation. This suggests concurrent and strong climatic and marine cooling in the area covering the northernmost parts of Finland, Norway, and Sweden during the climate event. In this area ecosystem response to the 8.2 ka event can therefore be expected to have been prominent, which in turn should be reflected in the contemporary human socio-economic systems. A study that employs lithic technological, statistical, and spatial analyses of Late Mesolithic (ca. 8450-6850 cal BP) lithic technology and settlement configuration in the area indicates that lithic technology and settlement patterns were reorganised following the climatic and marine cooling. The studied groups changed their lithic technology as a result of developments that led to increased use of terrestrial resources and an accompanying long-distance coast/inland residential mobility pattern. Besides lithic technological changes and long-distance mobility on land, decreased marine productivity probably also explains the disappearance of semi-subterranean houses from the coast at ca. 8200 cal BP, while their reappearance after ca. 7500 cal BP can be linked to a increased influx of warm salty water into the Barents Sea. The results suggest that in the past a long period of decreased influx of Atlantic water into the Barents Sea has had disastrous consequences for the marine ecosystem. At present the Barents Sea fisheries have notable economic importance and produce, for example, over 90% of the Norwegian Atlantic cod (Gadus morhua) catch.

  9. Benchmarking MELCOR 1.8.2 for ITER Against Recent EVITA Results

    2007-11-01

    A version of MELCOR 1.8.2 modified for use in ITER Preliminary Safety Report analyses was validated against recent data from the EVITA facility located in Cadarache, France. EVITA Test Series 7 was used for this study to verify MELCOR’s ability to predict the pressures, temperatures, cryoplate ice mass, and vaccum vessel (VV) condensate mass for test conditions in EVITA that include injections of steam, nitrogen, and water in to the EVITA VV after the walls had been heated to 165 ºC and the cryoplate had been cooled to -193 ºC. In general, the ability of MELCOR to predict the VV pressure and wall temperatures for the steam only and water only injection tests was very good. Predicted ice layer masses where larger than reported for the EVITA cryoplate, in particular for the steam only injection tests (~40% too high), and the predicted condensate masses were less that measured in EVITA. Both of these descrpancies can be explained by ice porosity. The modified MELCOR 1.8.2 over predicts the EVITA VV pressure for the co-injection tests (e.g., steam plus nitrogen, or water plus nitrogen injections) by almost a factor of two. Based on parametric runs that where made by increasing the predicted cryoplate condensation rate, it is believed that this pressure over prediction is a result of an under predicted cryoplate condensation rate. The particulars of this study are documented in this report as well as conclusions about the impact this study has regarding the use of this verions of MELCOR for consequence analyses for ITER safety reports.

    The study investigated prenatal alcohol consumption and knowledge of alcohol risks and fetal alcohol syndrome among Korean women. The participants were 221 Korean women who attended the post-partum care centers in Seoul, Korea. The data included the participants' background characteristics, quantity-frequency typology, Student Alcohol Questionnaire, and a scale on the participants' knowledge of fetal alcohol syndrome. Alcohol was consumed during pregnancy by 12.7% of the participants. Of these, 60.7% drank alcohol with their spouse. A few participants reported that nurses identified their drinking habits and gave them information on alcohol consumption and fetal alcohol syndrome. Most of the participants did not have the opportunity for prenatal counseling about fetal alcohol syndrome. The knowledge level regarding alcohol risks and fetal alcohol syndrome among the participants was poor. Alcohol consumption before pregnancy was significantly related to prenatal alcohol consumption. Prenatal alcohol consumption was not related to knowledge about alcohol consumption and fetal alcohol syndrome. The assessment of alcohol consumption and counseling about alcohol are needed for pregnant women in order to prevent fetal alcohol syndrome.

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

Alcohol intake can modify worker's behaviour (impaired judgement and vigilance, dulled reflexes) causing reduced performance, mistakes during operating procedures, accidents and injuries. Moreover it can affect the toxicokinetic and toxicodinamic properties of several substances in the workplace, inducing a more complex evaluation of exposure assessment and diagnostic procedures of occupational diseases. The occupational physician, during health surveillance program, can face several alcohol related issues. These entail diagnostic evaluation of alcoholism, job fitness evaluation, in heavy drinkers, advise of rehabilitation and health promotion program.

    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

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

    2013-01-01

    We compared four simulations of the 8.2 ka event to assess climate model sensitivity and skill in responding to North Atlantic freshwater perturbations. All of the simulations used the same freshwater forcing, 2.5 Sv for one year, applied to either the Hudson Bay (northeastern Canada) or Labrador Sea (between Canada's Labrador coast and Greenland). This freshwater pulse induced a decadal-mean slowdown of 10-25%in the Atlantic Meridional Overturning Circulation (AMOC) of the models and caused a large-scale pattern of climate anomalies that matched proxy evidence for cooling in the Northern Hemisphere and a southward shift of the Intertropical Convergence Zone. The multi-model ensemble generated temperature anomalies that were just half as large as those from quantitative proxy reconstructions, however. Also, the duration of AMOC and climate anomalies in three of the simulations was only several decades, significantly shorter than the duration of approx.150 yr in the paleoclimate record. Possible reasons for these discrepancies include incorrect representation of the early Holocene climate and ocean state in the North Atlantic and uncertainties in the freshwater forcing estimates.

  4. MELCOR 1.8.2 Assessment: IET direct containment heating tests

    MELCOR is a fully integrated, engineering-level computer code, being developed at Sandia National Laboratories for the USNRC, that models the entire spectrum of severe accident phenomena in a unified framework for both BWRs and PWRS. As part of an ongoing assessment program, the MELCOR computer code has been used to analyze several of the IET direct containment heating experiments done at 1:10 linear scale in the Surtsey test facility at Sandia and at 1:40 linear scale in the corium-water thermal interactions (CWTI) COREXIT test facility at Argonne National Laboratory. These MELCOR calculations were done as an open post-test study, with both the experimental data and CONTAIN results available to guide the selection of code input. Basecase MELCOR results are compared to test data in order to evaluate the new HPME DCH model recently added in MELCOR version 1.8.2. The effect of various user-input parameters in the HPME model, which define both the initial debris source and the subsequent debris interaction, were investigated in sensitivity studies. In addition, several other non-default input modelling changes involving other MELCOR code packages were required in our IET assessment analyses in order to reproduce the observed experiment behavior. Several calculations were done to identify whether any numeric effects exist in our DCH IET assessment analyses.

  7. Reactivity to alcohol cues and induced moods in alcoholics.

    PubMed

    1990-01-01

    It has been theorized that respondent conditioning processes in part underlie desire for alcohol and thus contribute to relapse after alcoholism treatment. One implication of this theory is that the relevant conditioned responses could be eliminated by respondent extinction, in which the alcoholic patient is exposed to alcohol-related stimuli while being prevented from consuming alcohol. However, exteroceptive cues such as the sight and smell of alcoholic beverages are not always sufficient to elicit desire for alcohol. In view of this, it has been suggested that interoceptive cues, such as mood states, may also play a role in eliciting desire for alcohol. To test this, eight alcoholic subjects were induced to experience negative or neutral moods on four separate days, and then exposed to the sight and smell of their favorite alcoholic drink, and to a neutral stimulus (seltzer water), in a within-subjects design. Results from this work indicate that: (a) negative moods can be reliably induced in the laboratory as confirmed by subjects' reports; (b) exposure to alcohol cues had no effect on desire for alcohol while subjects were in a relaxed, neutral mood state; (c) the presence of negative mood states alone appeared to be sufficient to elicit desire for alcohol in some subjects, regardless of whether alcohol or water was presented. These data argue that negative mood states may cue desire for alcohol independent of other cues. The data also suggest that reactivity to alcohol cues may be substantially reduced by relaxation.

    There is good though not conclusive evidence that a small to modest average daily intake of alcohol--that is, 20-30 g/day is associated with increased longevity due mainly to a reduction in death from cardiovascular disease. Larger average daily alcohol intakes--especially those in excess of 60 g/day for men and 40 g/day for women--are associated with gradually increasing morbidity and mortality rates from a variety of diseases. Alcohol may be unrecognised as the cause of somatic disease, which can occur without overt psychosocial evidence of alcohol abuse, unless the index of suspicion is high and a thorough drink history obtained. Laboratory tests for the detection and/or confirmation of alcohol abuse are useful but subject to serious limitations being neither as sensitive nor specific as sometimes believed. The value of random blood and/or breath alcohol measurements, in outpatients, as an aid to diagnosis of alcohol-induced organic disease is probably not sufficiently appreciated and, though relatively insensitive, is highly specific.

    Agarwal-Kozlowski, K; Agarwal, D P

    2000-04-01

    A number of socio-economic, cultural, biobehavioral factors and ethnic/gender differences are among the strongest determinants of drinking patterns in a society. Both epidemiological and clinical studies have implicated the excessive use of alcohol in the risk of developing a variety of organ, neuronal and metabolic disorders. Alcohol abuse related metabolic derangements affect almost all body organs and their functions. Race and gender differences in drinking patterns may play an important role in the development of medical conditions associated with alcohol abuse. The incidence of alcoholism in a community is influenced by per capita alcohol consumption and covariates with the relative price and availability of alcoholic drinks. The majority of the family, twin and adoption studies suggest that alcoholism is familial, a significant proportion of which can be attributed to genetic factors. The question is how much of the variance is explained by genetic factors and to what degree is this genetically mediated disorder moderated by personal characteristics. Among the most salient personal characteristics moderating, the genetic vulnerability may be factors such as age, ethnicity, and presence of psychiatric co morbidity. Cultural factors and familial environmental factors are most likely predictors as well.

    The authors examined problem-solving marital interactions of alcoholic and nonalcoholic couples (N = 132). Four alcoholic groups (husband alcoholic with antisocial personality disorder or not, paired with alcoholic or nonalcoholic wives) were compared with each other and with a both-spouses-nonalcoholic group. Consistent with the alcoholic subtypes hypothesis, couples with an antisocial alcoholic husband had higher levels of hostile behavior regardless of wives’ alcoholism status. In contrast, rates of positive behaviors and the ratio of positive to negative behaviors were greatest among couples in which either both or neither of the spouses had alcoholic diagnoses and were lowest among alcoholic husbands with nonalcoholic wives. Discussion focuses on possible mechanisms linking antisocial alcoholism and discrepant alcoholic diagnoses to poorer marital outcomes. PMID:16492103

  13. Foreshock triggering of the 1 April 2014 Mw 8.2 Iquique, Chile, earthquake

    NASA Astrophysics Data System (ADS)

    Herman, Matthew W.; Furlong, Kevin P.; Hayes, Gavin P.; Benz, Harley M.

    2016-08-01

    On April 1st, 2014, a Mw 8.2 (U.S. Geological Survey moment magnitude) earthquake occurred in the subduction zone offshore northern Chile. In the two weeks leading up to the earthquake, a sequence of foreshocks, starting with a Mw 6.7 earthquake on March 16th and including three more Mw 6.0+ events, occurred predominantly south of the April 1st mainshock epicenter and up-dip of the area of significant slip during the mainshock. Using earthquake locations and source parameters derived in a previous study (Hayes et al., 2014) and a Coulomb failure stress change analysis of these events, we assess in detail the hypothesis that the earthquakes occurred as a cascading sequence, each event successively triggering the next, ultimately triggering the rupture of the mainshock. Following the initial Mw 6.7 event, each of the three largest foreshocks (Mw 6.4, 6.2 and 6.3), as well as the hypocenter of the mainshock, occurred in a region of positive Coulomb stress change produced by the preceding events, indicating these events were brought closer to failure by the prior seismicity. In addition, we reexamine the possibility that aseismic slip occurred and what role it may have played in loading the plate boundary. Using horizontal GPS displacements from along the northern Chile coast prior to the mainshock, we find that the foreshock seismicity alone likely does not account for the observed signals. We perform a grid search for the location and magnitude of an aseismic slip patch that can account for the difference between observed signals and foreshock-related displacement, and find that a slow slip region with slip corresponding to a Mw ∼ 6.8 earthquake located coincident with or up-dip of the foreshock seismicity can best explain this discrepancy. Additionally, such a slow slip region positively loads the mainshock hypocentral area, enhancing the positive loading produced by the foreshock seismicity.

    The performance of the Cassegrain Adaptive Optics (AO) system of the 8.2 m Subaru Telescope is reported. The system is based on a curvature wavefront sensor with 36 photon-counting avalanche photodiode modules and a bimorph wavefront correcting deformable mirror with 36 driving electrodes. This AO system has been in service since 2002 April for two open-use instruments, an infrared camera and spectrograph (IRCS) and a coronagraph imager with adaptive optics (CIAO). The Strehl ratio in the K-band is around 0.3 when a bright guide star is available under 0".4 seeing condition. High sensitivity of the wavefront sensor allows significant improvement in the image quality, even for faint guide stars down to R=18 mag. The design of the new Nasmyth Adaptive Optics system with 188 control elements under construction is described. This new system with fivefold increase in the number of control elements will provide twice higher Strehl ratio of 0.7. To increase the sky coverage for this new system, a power laser system to produce an artificail guide star in the upper atmosphere is also under construction. The AO system with laser guide capability enables the coverage up to 80% of the entire sky and offers diffraction limited observation for almost any target in the sky. An all solid-state 4W laser to generate the sodium D line emission by summing the two YAG laser frequencies is under development. The generated laser beam is tranmitted through a photonic crystal fiber to the laser launching telescope attached at the backside of the secondary mirror. Expected performance of this laser guide Nasmyth AO system is shown.

    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

    Man has consumed alcohol for its euphoric and sedative effect down through the ages. Attention in the medical literature has been primarily focused on the effects of alcohol on the nervous system and liver. In the past few years, isolated reports have appeared in the medical literature concerning the effects of alcohol on the bony skeleton. The purpose of this paper is to classify these lesions, discuss their pathophysiology, and briefly review their clinical course. The lesions discussed include osteoporosis, hip fractures, aseptic necrosis of the hip, and fat embolism. For the purpose of this discussion these lesions are divided into two groups. Group I includes the battered alcoholic syndrome. Group II includes fat embolism, both acute and chronic, and aseptic necrosis of the hip. ImagesFigure 1Figure 2Figure 3Figure 4Figure 5 PMID:522187

    Alcoholic cardiomyopathy is a specific heart muscle disease found in individuals with a history of long-term heavy alcohol consumption. Alcoholic cardiomyopathy is associated with a number of adverse histological, cellular, and structural changes within the myocardium. Several mechanisms are implicated in mediating the adverse effects of ethanol, including the generation of oxidative stress, apoptotic cell death, impaired mitochondrial bioenergetics/stress, derangements in fatty acid metabolism and transport, and accelerated protein catabolism. In this review, we discuss the evidence for such mechanisms and present the potential importance of drinking patterns, genetic susceptibility, nutritional factors, race, and sex. The purpose of this review is to provide a mechanistic paradigm for future research in the area of alcoholic cardiomyopathy. PMID:24671642

    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? Would it have been possible to change his outcome? PMID:25559647

    Alcohol use--and abuse--has always been more prevalent among males than among females. The sex role prescription for men to affirm their masculinity by drinking is a major determinant of this sex difference. This paper reviews the intricate interrelationship between masculinity and both social and alcoholic drinking. A large body of evidence indicates that social drinking is a primary cultural symbol of manliness; portrayals in the media strengthen this association. Less evidence exists to connect masculinity issues with alcoholic dependence, but there has been much speculation: Three psychodynamic theories of alcoholism--the repressed homosexuality, dependency, and power theories--hypothesized that men who drink addictively have the most fragile masculine identities. The 1980s have witnessed a widespread recognition of the dangers of equating drinking and manliness, and societal changes suggest that drinking may be gradually losing its masculine aura.

  8. Revisiting the November 27, 1945 Makran (Mw=8.2) interplate earthquake

    Makran Subduction Zone (MSZ) in southern Iran and southwestern Pakistan is a zone of convergence, where the remnant oceanic crust of Arabian plate is subducting beneath the Eurasian plate with a rate of less than 30 mm/yr. The November 27, 1945 earthquake (Mw=8.2) in eastern section of Makran followed by a tsunami, at some points 15 meters high. More than 4000 victims and widespread devastation along the coastal area of Pakistan, Iran, Oman and India are reported for this earthquake. We have collected the old seismograms of the 1945 earthquake and its largest following earthquake (August 5, 1947, Mw=7.3) from a number of stations around the globe. Using ISS data, we relocated these two events. We used the teleseismic body-waveform inversion code of Kikuchi and Kanamori to determine the slip distribution of these two earthquakes for the first time. The results show that the extent of rupture of the 1945 earthquake is larger than what previously had been approximated in other studies. The slip distribution suggests two distinct sets of asperities with different behavior in the west close to Pasni and in the east close to Ormara. The highest slip was obtained for an area between these two cities which shows geological evidence of rapid uplift. To associate this behavior with the structure of slab interface we studied the TPGA (Trench Parallel Free-air Gravity Anomaly) and TPBA (Trench Parallel Bouguer Anomaly) in MSZ. The results of TPGA does not show the expected phenomenon, which is the correlation of asperities with the area of highly negative TPGA. However, TPBA can make correlation between the observed slip distribution and the structure of slab interface. Using the topography and gravity profiles perpendicular to trench and along the MSZ, we could observe the segmentation in the slab interface. This confirms that we barely expect that the whole interface releases energy in one single megathrust earthquake. Current seismicity in MSZ, although sparse, can fairly

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

    A series of novel anion exchange composite membrane (QCS/PS-G8-2-8) were synthesized based on the quaternized chitosan (QCS, DQ = 89.20 (±3.50)%) blended with block polymer of polystyrene (PS) and G8-2-8 (maleic acid diethyl brace base pairs [octyl dimethyl chloride/ammonium bromide]). Then the QCS was cross-linked by glutaraldehyde (GA). The parameters including adsorption time (t), pH, and initial concentration of Rhodamine B (C0), temperature (T), the mass fraction of G8-2-8 and GA (WGA) on the adsorption were investigated to determine the optimum condition for the removal of RB. The kinetic and thermodynamic properties of the adsorption process were also discussed. The optimum adsorption condition was that the adsorption time was 100 min, pH was 4, the initial concentration of RB was 100 mg L-1, the mass fraction of G8-2-8 was 5.0 wt%, the mass fraction of GA was 2.0 wt%, the temperature was 40 °C. Thus, RB optimum adsorption capacity (q) of the composite membrane QCS/PS-G8-2-8 (5.0%) (G8-2-8 mass content (wt.%) was 5.0%) was 17.04 mg g-1. The adsorption isotherm of the RB on the composite membrane can be well fitted with the Temkin equation. The adsorption kinetics can be well described by the pseudo-second-order kinetics model. The values of ΔG, ΔH and ΔS indicated that the adsorption of RB onto QCS/PS-G8-2-8 was spontaneous and exothermic.

    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

    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

  13. [Clinical concept of alcoholic dementia].

    PubMed

    Kato, N

    1991-06-01

    Intellectual deterioration, changing in behavior and affect are often seen in association with long continued and heavy alcohol ingestion and such deteriorated states of patients are called alcoholic dementia. A large number of investigators have attempted to designate clinical concept of alcoholic dementia throughout the centuries and many kinds of term like as alcoholic pseudo-paralysis, alcoholic mental deficiency and alcoholic deterioration, etc, have been submitted since the beginning of 19th century. Numerous psychometric studies have indicated cognitive impairment and memory disturbance in chronic alcohol abusers and moreover brain PEG and CT-scan studies have shown sulcal widening and enlarged ventricles to be common in alcoholics. However, alcoholic dementia is hard to classify as a distinct disorder caused by alcoholic ingestion. The reason is lack of specific findings, both clinical and histopathological, like as Wernicke-Korsakoff syndrome and other nutritional disorders in alcoholics. Victor, M. describes in his work the majority of patients who have come to autopsy with the clinical diagnosis of primary alcoholic dementia have shown the lesions of the Wernicke-Korsakoff syndrome and he postulates alcoholic dementia is heavily contaminated with burned-out Wernicke-Korsakoff disease. The clinical and pathological observations presented by this time represent alcoholic dementia is a residual category for cases in which there are severe impairment of intelligence with marked deterioration of personality following prolonged and heavy drinking.

    OBJECTIVE: This study used prospective data to test the hypothesis that exposure to alcohol advertising contributes to an increase in underage drinking and that an increase in underage drinking then leads to problems associated with drinking alcohol. METHODS: A total of 3890 students were surveyed once per year across 4 years from the 7th through the 10th grades. Assessments included several measures of exposure to alcohol advertising, alcohol use, problems related to alcohol use, and a range of covariates, such as age, drinking by peers, drinking by close adults, playing sports, general TV watching, acculturation, parents’ jobs, and parents’ education. RESULTS: Structural equation modeling of alcohol consumption showed that exposure to alcohol ads and/or liking of those ads in seventh grade were predictive of the latent growth factors for alcohol use (past 30 days and past 6 months) after controlling for covariates. In addition, there was a significant total effect for boys and a significant mediated effect for girls of exposure to alcohol ads and liking of those ads in 7th grade through latent growth factors for alcohol use on alcohol-related problems in 10th grade. CONCLUSIONS: Younger adolescents appear to be susceptible to the persuasive messages contained in alcohol commercials broadcast on TV, which sometimes results in a positive affective reaction to the ads. Alcohol ad exposure and the affective reaction to those ads influence some youth to drink more and experience drinking-related problems later in adolescence. PMID:23359585

  15. Invertebrate models of alcoholism.

    PubMed

    Scholz, Henrike; Mustard, Julie A

    2013-01-01

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

  16. Alcoholic myopathy and acetaldehyde.

    PubMed

    Preedy, Victor R; Crabb, David W; Farrés, Jaume; Emery, Peter W

    2007-01-01

    Alcoholic myopathy is characterized by biochemical and morphological lesions within muscle, ranging from impairment of muscle strength and loss of lean tissue to cellular disturbances and altered gene expression. The chronic form of the disease is five times more common than cirrhosis and is characterized by selective atrophy of type 11 (anaerobic) fibres: type I (aerobic) fibres are relatively protected. Although the causative agent is known (i.e. ethanol), the intervening steps between alcohol ingestion and the development of symptoms and lesions are poorly understood. However, acetaldehyde appears to have an important role in the aetiology of the disease. For example, alcohol is a potent perturbant of muscle protein synthesis in vivo, and this effect is exacerbated by cyanamide pre-dosage, which raises acetaldehyde concentrations. Acetaldehyde alone also reduces muscle protein synthesis in vivo and proteolytic activity in vitro. The formation of acetaldehyde protein adducts is another mechanism of putative importance in alcoholic myopathy. These adducts are formed within muscle in response to either acute or chronic alcohol exposure and the adducts are located preferentially within the sarcolemmal and sub-sarcolemmal regions. However, the significance of protein adduct formation is unclear since we do not currently know the identity of the adducted muscle proteins nor whether adduction alters the biochemical or functional properties of skeletal muscle proteins.

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

    The 8.2 ka BP event could provide important information for predicting abrupt climate change in the future. Although published records show that the East Asian monsoon area responded to the 8.2 ka BP event, there is no high-resolution quantitative reconstructed climate record in this area. In this study, a reconstructed 10-year moving average annual rainfall record in southwest China during the 8.2 ka BP event is presented by comparing two high-resolution stalagmite δ18O records from Dongge cave and Heshang cave. This decade-scale rainfall reconstruction is based on a central-scale model and is confirmed by inter-annual monitoring records, which show a significant positive correlation between the regional mean annual rainfall and the drip water annual average δ18O difference from two caves along the same monsoon moisture transport pathway from May 2011 to April 2014. Similar trends between the reconstructed rainfall and the stalagmite Mg / Ca record, another proxy of rainfall, during the 8.2 ka BP period further increase the confidence of the quantification of the rainfall record. The reconstructed record shows that the mean annual rainfall in southwest China during the central 8.2 ka BP event is less than that of present (1950-1990) by ˜ 200 mm and decreased by ˜ 350 mm in ˜ 70 years experiencing an extreme drying period lasting for ˜ 50 years. Comparison of the reconstructed rainfall record in southwest China with Greenland ice core δ18O and δ15N records suggests that the reduced rainfall in southwest China during the 8.2 ka BP period was coupled with Greenland cooling with a possible response rate of 110 ± 30 mm °C-1.

    There is little information on the echocardiographic evaluation of left ventricular performance after the ingestion of alcohol. Therefore, we obtained echocardiograms and systolic time intervals in 9 normal subjects before and after a cocktail party. These subjects drank 5-6 ounces of 87 proof whiskey during the party. An additional 19 normal subjects drank 3 ounces of 87 proof whiskey and had similar studies performed. The results of the study with 5-6 ounces of alcohol are in Table 3. The 19 subjects who drank 3 ounces of alcohol showed no statistical changes except that the systolic ejection time fell from a control of 0.31 +/- 03 (see formula in text) to 0.30 +/- 0.4 (P less than 0.05). These data indicate that 5-6 ounces of whiskey can depress left ventricular function in normal subjects.

    Recent preclinical and clinical evidence using prazosin indicates that α(1) -blockade may represent a new approach to treat alcohol dependence (AD). While most of the alcohol research on α(1) -blockade has been conducted testing prazosin, O'Neil and colleagues recently performed a set of preclinical experiments testing another α(1) -blocker, doxazosin, which has a longer half-life that may enhance clinical utility. Doxazosin and prazosin share the same chemical structure, in which the central element is a piperazine ring. O'Neil and colleagues' main results are that doxazosin significantly reduced alcohol intake without affecting locomotor activity. As such, O'Neil and colleagues provide the first preclinical evidence of the possible role of doxazosin in AD. Additional translational research is needed to further test this hypothesis.

    Alcoholism is characterized by a lack of control over excessive alcohol consumption despite significant negative consequences. This impulsive and compulsive behavior may be related to functional abnormalities within networks of brain regions responsible for how we make decisions. The abnormalities may result in strengthened networks related to appetitive drive—or the need to fulfill desires—and simultaneously weakened networks that exercise control over behaviors. Studies using functional magnetic resonance imaging (fMRI) in abstinent alcoholics suggest that abstinence is associated with changes in the tone of such networks, decreasing resting tone in appetitive drive networks, and increasing resting tone in inhibitory control networks to support continued abstinence. Identifying electroencephalographic (EEG) measures of resting tone in these networks initially identified using fMRI, and establishing in longitudinal studies that these abstinence-related changes in network tone are progressive would motivate treatment initiatives to facilitate these changes in network tone, thereby supporting successful ongoing abstinence.

    Sugarbeets are a prime candidate for alcohol fuel production because they store their energy and much of their biomass as sucrose, a fermentable sugar. At the present time, it is uneconomical to produce alcohol from sugarbeets and the balance is marginal. A number of approaches could improve both the economic and the energy situation: 1) increasing production per acre; 2) reducing conversion costs; 3) integrating sugarbeet - sweet sorghum crops; and 4) utilizing low priority sources such as geothermal, coal, bagasse and solar for the energy of conversion.

    Concomitant use of alcohol and medications may lead to potentially serious medical conditions. Increasing prescription medication abuse in today's society necessitates a deeper understanding of the mechanisms involved in alcohol-medication interactions in order to help prevent adverse events. Interactions of medications with alcohol result in altered bioavailability of the medication or alcohol (pharmacokinetic interactions) or modification of the effects at receptor or ion channel sites to alter behavioral or physical outcome (pharmacodynamic interactions). The nature of pharmacokinetic or pharmacodynamic interactions involved in alcohol-medication interactions may differ between acute and chronic alcohol use and be influenced by race, gender, or environmental or genetic factors. This review focuses on the mechanisms underlying pharmacokinetic and pharmacodynamic interactions between alcohol and medications and provides examples for such interactions from replicated research studies. In conclusion, further translational research is needed to address several gaps in our current knowledge of alcohol-medication interactions, including those under various pathologic conditions.

  4. The sheep KAP8-2 gene, a new KAP8 family member that is absent in humans.

    The keratin-associated proteins (KAPs) are fundamental components of hair and wool fibres, and are believed to in part be responsible for some of the properties of these fibres. KAPs can be divided into three groups: the high sulphur (HS) KAPs, the ultra-high sulphur (UHS) KAPs and the high glycine-tyrosine (HGT) KAPs. KAP8 is a HGT-KAP family and was believed to be coded for by a single gene in both humans and sheep. However, the recent identification of a KAP8-2 gene in goats led us to investigate whether a KAP8-2 gene exists in sheep. A BLAST search of the Ovine Genome Assembly v2.0 using the coding sequence of caprine KRTAP8-2 identified a homologous region on sheep chromosome 1 (OAR1:123005473_123005664; E = e(-101)). This region was clustered with a number of previously identified KAP genes including (in order from the centromere) KRTAP11-1, KRTAP7-1, KRTAP8-1, KRTAP6-2, KRTAP6-1, KRTAP13-3 and KRTAP24-1. PCR-SSCP analysis of the notional gene revealed two dissimilar PCR-SSCP banding patterns, representing two DNA sequences. A single nucleotide difference 21 bp upstream of the TATA box was identified. The two sequences did not have great homology with known ovine KRTAP sequences, but high sequence identity was found with KRTAP8-2 from goats and reindeer. These results suggest that sheep possess a KAP8-2 gene and that this gene is polymorphic. The notional KAP8-2 protein is comprised of 63 amino acid residues and is rich in glycine and tyrosine, but has a low cysteine content. In contrast to other HGT-KAPs, ovine KAP8-2 contains more acidic amino acid residues, and this would likely result in a lower isoelectric point (pI) of 6.3. PMID:25279319

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

    Prenatal alcohol exposure (PAE) is one of the most prevalent and modifiable risk factors for somatic, behavioral, and neurological abnormalities. Affected individuals exhibit a wide range of such features referred to as fetal alcohol spectrum disorders (FASD). These are characterized by a more or less specific pattern of minor facial dysmorphic features, growth deficiency and central nervous system symptoms. Nevertheless, whereas the diagnosis of the full-blown fetal alcohol syndrome does not pose a major challenge, only a tentative diagnosis of FASD can be reached if only mild features are present and/or maternal alcohol consumption during pregnancy cannot be verified. The respective disorders have lifelong implications. The teratogenic mechanisms induced by PAE can lead to various additional somatic findings and structural abnormalities of cerebrum and cerebellum. At the functional level, cognition, motor coordination, attention, language development, executive functions, memory, social perception and emotion processing are impaired to a variable extent. The long-term development is characterized by disruption and failure in many domains; an age-adequate independency is frequently not achieved. In addition to primary prevention, individual therapeutic interventions and tertiary prevention are warranted; provision of extensive education to affected subjects and their caregivers is crucial. Protective environments are often required to prevent negative consequences such as delinquency, indebtedness or experience of physical/sexual abuse.

    2002-01-01

    The proteome is the complete set of proteins in an organism. It is considerably larger and more complex than the genome--the collection of genes that encodes these proteins. Proteomics deals with the qualitative and quantitative study of the proteome under physiological and pathological conditions (e.g., after exposure to alcohol, which causes major changes in numerous proteins of different cell types). To map large proteomes such as the human proteome, proteins from discrete tissues, cells, cell components, or biological fluids are first separated by high-resolution two-dimensional electrophoresis and multidimensional liquid chromatography. Then, individual proteins are identified by mass spectrometry. The huge amount of data acquired using these techniques is analyzed and assembled by fast computers and bioinformatics tools. Using these methods, as well as other technological advances, alcohol researchers can gain a better understanding of how alcohol globally influences protein structure and function, protein-protein interactions, and protein networks. This knowledge ultimately will assist in the early diagnosis and prognosis of alcoholism and the discovery of new drug targets and medications for treatment.

    2007-01-01

    Recent epidemiological studies indicate that alcohol consumption in women has increased in the last few years, which suggests that alcoholism in women will also increase in the near future. Moreover, this disease shows differential characteristics in women, and knowledge of these characteristics is important so that treatment can begin as early as possible. The objective of the present study was to explore clinical differences in alcohol use disorders according to patients' gender. It was carried out with a sample of 370 patients, 325 men (87.8%) and 45 women (12.2%), with mean ages of 42.83 and 44.6 years, respectively. The patients were assessed through the Europasi interview and analytical studies with liver enzyme profiles and blood tests. The most notable results were: women began alcohol consumption significantly later than men (19.61 and 16.9 years, respectively; p < 0.008); they were significantly older than men when the consumption pattern became problematic (30.93 and 24.68 years, respectively; p < 0.003); they had been drinking for fewer years (13.26 versus 17.85 years; p < 0.02); and they drank fewer grams of alcohol (117.7 and 133.8 g., respectively; n.s.). Women scored significantly higher than men on the Europasi psychiatric scale (2.91 and 1.97, respectively; p < 0.007) and men had more legal problems than women (1.2 and 1.0, respectively; p < 0.000). In the biological tests the GGT enzyme values were higher in men (137.51) than in women (96.7), but this difference was not significant, and the VCM value was significantly higher for women (98.1) than for men (95.05). Another important finding was that the percentage of women who had sought private professional help was higher than that of men (15% versus 4.6%; p < 0.01). PMID:18173101

    2010-01-01

    Brief alcohol counseling interventions can reduce alcohol consumption and related morbidity among non-dependent risky drinkers, but more intensive alcohol treatment is recommended for persons with alcohol dependence. This study evaluated whether scores on common alcohol screening tests could identify patients likely to have current alcohol dependence so that more appropriate follow-up assessment and/or intervention could be offered. This cross-sectional study used secondary data from 392 male and 927 female adult family medicine outpatients (1993–1994). Likelihood ratios were used to empirically identify and evaluate ranges of scores of the AUDIT, the AUDIT-C, two single-item questions about frequency of binge drinking, and the CAGE questionnaire for detecting DSM-IV past-year alcohol dependence. Based on the prevalence of past-year alcohol dependence in this sample (men: 12.2%; women: 5.8%), zones of the AUDIT and AUDIT-C identified wide variability in the post-screening risk of alcohol dependence in men and women, even among those who screened positive for alcohol misuse. Among men, AUDIT zones 5–10, 11–14 and 15–40 were associated with post-screening probabilities of past-year alcohol dependence ranging from 18–87%, and AUDIT-C zones 5–6, 7–9 and 10–12 were associated with probabilities ranging from 22–75%. Among women, AUDIT zones 3–4, 5–8, 9–12 and 13–40 were associated with post-screening probabilities of past-year alcohol dependence ranging from 6–94%, and AUDIT-C zones 3, 4–6, 7–9 and 10–12 were associated with probabilities ranging from 9–88%. AUDIT or AUDIT-C scores could be used to estimate the probability of past-year alcohol dependence among patients who screen positive for alcohol misuse and inform clinical decision-making.

    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.

    Cool conditions, known as the "8.2 ka event", occurred between 8400 and 7900 cal yr B.P. in Greenland, Europe and elsewhere in the North Atlantic. The impact of this brief cool interval on local forests is recorded in radiocarbon-dated, high-resolution pollen stratigraphies for New Long Pond (41^{0}50'N, 70^{0}42'W) and Davis Pond (42^{0}30'N, 73^{0}19'W), Massachusetts. The vegetation response to the event is recorded differently for regions with contrasting soil types. At New Long Pond, the sandy outwash derived soils are associated with changes in jack/red, white and pitch pine populations, whereas the dominant changes in vegetation for the clay-rich, proglacial lake derived soils around Davis Pond are among oak, hemlock, and beech. At both sites, pollen evidence for the "8.2 ka event" may be easily overlooked within the more dominant regional pattern for the Northeast, which shows a shift from dry to moist conditions in conjunction with changes from predominantly white pine to oak with more mesic plant taxa between 9000 and 8000 cal yr B.P. At New Long Pond, the "8.2 ka event" is brief, preceded by a low-stand in water-level during the early Holocene and dominated by white pine pollen. After 9000 cal yr B.P., pitch pine with beech, maple, hop/hornbeam, elm and ash pollen indicate a mixed mesophytic forest. A radiocarbon-dated decrease in loss-on-ignition values at 8400 cal yr B.P., likely related to a drawdown in lake level, distinguishes the "8.2 event" and helps highlight subtle shifts in vegetation that favor colder and drier conditions than before the event. Following this brief episode, the pollen data indicate a return to warm and moist conditions until about 5600 years ago. At Davis Pond, increased oak and decreased hemlock pollen abundances, followed by an increase in beech pollen abundance is evident and show what may be the dominant regional pollen signature for the "8.2 ka event" in the Northest. This pattern is also recorded at nearby Berry and

    Alcohol consumption is common across subpopulations in the United States. However, the health burden associated with alcohol consumption varies across groups, including those defined by demographic characteristics such as age, race/ethnicity, and gender. Large national surveys, such as the National Epidemiologic Survey on Alcohol and Related Conditions and the National Survey on Drug Use and Health, found that young adults ages 18–25 were at particularly high risk of alcohol use disorder and unintentional injury caused by drinking. These surveys furthermore identified significant variability in alcohol consumption and its consequences among racial/ethnic groups. White respondents reported the highest prevalence of current alcohol consumption, whereas alcohol abuse and dependence were most prevalent among Native Americans. Native Americans and Blacks also were most vulnerable to alcohol-related health consequences. Even within ethnic groups, there was variability between and among different subpopulations. With respect to gender, men reported more alcohol consumption and binge drinking than women, especially in older cohorts. Men also were at greater risk of alcohol abuse and dependence, liver cirrhosis, homicide after alcohol consumption, and drinking and driving. Systematic identification and measurement of the variability across demographics will guide prevention and intervention efforts, as well as future research. PMID:27159807

    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.

    2014-01-01

    Alcoholism results in about 2.5 million deaths annually worldwide, representing 4% of all mortality. Although alcoholism is associated with more than 60 diseases, most mortality from alcoholism results from alcoholic liver disease (ALD). ALD includes alcoholic steatosis, alcoholic hepatitis, and alcoholic cirrhosis, in order of increasing severity. Important scoring systems of ALD severity include: Child-Pugh, a semi-quantitative scoring system useful to roughly characterize clinical severity; model for end-stage liver disease, a quantitative, objective scoring system used for prognostication and prioritization for liver transplantation; and discriminant function, used to determine whether to administer corticosteroids for alcoholic hepatitis. Abstinence is the cornerstone of ALD therapy. Psychotherapies, including twelve-step facilitation therapy, cognitive-behavioral therapy, and motivational enhancement therapy, help support abstinence. Disulfiram decreases alcohol consumption by causing unpleasant sensations after drinking alcohol from accumulation of acetaldehyde in serum, but disulfiram can be hepatotoxic. Adjunctive pharmacotherapies to reduce alcohol consumption include naltrexone, acamprosate, and baclofen. Nutritional therapy helps reverse muscle wasting, weight loss, vitamin deficiencies, and trace element deficiencies associated with ALD. Although reduced protein intake was previously recommended for advanced ALD to prevent hepatic encephalopathy, a diet containing 1.2-1.5 g of protein/kg per day is currently recommended to prevent muscle wasting.

    Background Non-alcoholic steatohepatitis (NASH) is a serious form of non-alcoholic fatty liver disease (NAFLD), associated with obesity and insulin resistance. Previous studies suggested that intestinal bacteria produced more alcohol in obese mice than lean animals. Methodology/Principal Findings To investigate whether alcohol is involved in the pathogenesis of NASH, the expression of inflammation, fibrosis and alcohol metabolism related genes in the liver tissues of NASH patients and normal controls (NCs) were examined by microarray (NASH, n = 7; NC, n = 4) and quantitative real-time PCR (NASH, n = 6; NC, n = 6). Genes related to liver inflammation and fibrosis were found to be elevated in NASH livers compared to normal livers. The most striking finding is the increased gene transcription of alcohol dehydrogenase (ADH) genes, genes for catalase and cytochrome P450 2E1, and aldehyde dehydrogenase genes. Immunoblot analysis confirmed the increased expression of ADH1 and ADH4 in NASH livers (NASH, n = 9; NC, n = 4). Conclusions/Significance The augmented activity of all the available genes of the pathways for alcohol catabolism suggest that 1) alcohol concentration was elevated in the circulation of NASH patients; 2) there was a high priority for the NASH livers to scavenge alcohol from the circulation. Our data is the first human evidence that suggests alcohol may contribute to the development of NAFLD. PMID:20221393

    Alcohol use disorder does not disappear with aging, neither the associated induced-suffering. While the prevalence of alcohol use disorder still remains around 10% in the subjects over 65 year old age, and daily encountered by hospital or nursing-home caregivers. Alcohol misuse is often overlooked in elderly people, which then obtain lesser care than younger adults although the care prognosis remains as good as or better than before the age of 65, alcoholic abstinence gets always a place among care offers to elders suffering of alcohol use disorders and dependence. However abstinence is a complex notion gathering various representations or meanings, and induces necessary psychological changes. Alcoholic abstinence seems thus to be feared by families or caregivers, because of lack of knowledge about the addictive dimension of the disorder. On behalf of ultimate freedom, and allowing a last pleasure, alcohol use disorders and its associated suffering can be neglected because abstinence is considered as aggressive and harmful. However, modalities of reduction of alcohol consumption as well as access control or regulated supply of alcoholic beverages, keep having a place in graduate care offers. Beyond the choice of decreasing or suppress drinking alcohol beverages, which only are terms or conditions of improvement, the main point remains the improvement of well-fare, quality of life and elders' health.

    According to the 'Report on alcohol fuels policy review', published in 1979 by the US Department of Energy, cheese whey had a very low net feedstock cost/gal of ethanol produced ($0.22) and the production potential in the USA is 90 million gal ethanol/yr. Three processes are described, i.e. the Milbrew whey fermentation process using Kluyveromyces fragilis with whey of 10-15% TS under sterile or non-sterile conditions and in batch, semi-continuous or continuous operation (primarily, designed for the production of single-cell protein), the continuous Carbery process in commercial operation in Ireland (DSA 42, 7856) and the Danish process (Dansk Gaerings-industri, Copenhagen) producing edible alcohol from whey permeate, and methane from distillation wastes for use as fuel for heating the distillation units.

    Whey disposal has become a serious environmental problem and loss of revenue to the cheese industry. The U.S. Dept. of Energy has indicated that cheese whey has one of the lowest net feedstock costs per gallon of ethanol. The manufacture of ethanol is accomplished by specially selected yeast fermentation of lactose via the glycolytic pathway. Three commercial processes are described, the Milbrew process which produces single cell protein and alcohol, and the Carbery and Denmark processes which produce potable alcohol. Selected strains of Kluveromyces fragilis are used in all processes and in the latter process, effluents are treated under anaerobic conditions to produce methane, which replaces 17-20% of the fuel oil required by the distillation plant.

    Alcoholic cardiomyopathy (ACM) is a specific heart muscle disease found in individuals with a history of long-term heavy alcohol consumption. ACM is associated with a number of adverse histological, cellular, and structural changes within the myocardium. Several mechanisms are implicated in mediating the adverse effects of ethanol, including the generation of oxidative stress, apoptotic cell death, impaired mitochondrial bioenergetics/stress, derangements in fatty acid metabolism and transport, and accelerated protein catabolism. In this review, we discuss the evidence for such mechanisms and present the potential importance of drinking patterns, genetic susceptibility, nutritional factors, race, and sex. The purpose of this review is to provide a mechanistic paradigm for future research in the area of ACM.

    Between one- and two-thirds of all alcohol abusers have impairment of muscle function that may be accompanied by biochemical lesions and/or the presence of a defined myopathy characterised by selective atrophy of Type II fibres. Perturbations in protein metabolism are central to the effects on muscle and account for the reductions in muscle mass and fibre diameter. Ethanol abuse is also associated with abnormalities in carbohydrate (as well as lipid) metabolism in skeletal muscle. Ethanol-mediated insulin resistance is allied with the inhibitory effects of ethanol on insulin-stimulated carbohydrate metabolism. It acutely impairs insulin-stimulated glucose and lipid metabolism, although it is not known whether it has an analogous effect on insulin-stimulated protein synthesis. In alcoholic cirrhosis, insulin resistance occurs with respect to carbohydrate metabolism, although the actions of insulin to suppress protein degradation and stimulate amino acid uptake are unimpaired. In acute alcohol-dosing studies defective rates of protein synthesis occur, particularly in Type II fibre-predominant muscles. The relative amounts of mRNA-encoding contractile proteins do not appear to be adversely affected by chronic alcohol feeding, although subtle changes in muscle protein isoforms may occur. There are also rapid and sustained reductions in total (largely ribosomal) RNA in chronic studies. Loss of RNA appears to be related to increases in the activities of specific muscle RNases in these long-term studies. However, in acute dosing studies (less than 1 day), the reductions in muscle protein synthesis are not due to overt loss of total RNA. These data implicate a role for translational modifications in the initial stages of the myopathy, although changes in transcription and/or protein degradation may also be superimposed. These events have important implications for whole-body metabolism.

    Progress in understanding the neuroscience of addiction has significantly advanced the development of more efficacious medications for the treatment of alcohol use disorders (AUD). While several medications have been approved by regulatory bodies around the world for the treatment of AUD, they are not universally efficacious. Recent research has yielded improved understanding of the genetics and brain circuits that underlie alcohol reward and its habitual use. This research has contributed to pharmacogenetic studies of medication response, and will ultimately lead to a more "personalized medicine" approach to AUD pharmacotherapy. This chapter summarizes work on clinically available medications (both approved by regulatory bodies and investigational) for the treatment of alcohol dependence, as well as the psychiatric disorders that are commonly comorbid with AUD. Studies that have evaluated genetic influences on medication response and those that have employed neuroimaging to probe mechanisms of medication action or response are highlighted. Finally, new targets discovered in animal models for possible pharmacologic intervention in humans are overviewed and future directions in medications development provided.

    Nonbeverage alcohol (NBA), or substitutes for traditional forms of beverage alcohol, includes such substances as mouthwash, aftershave lotion and alcohol-based fuels. Literature pertaining to the prevalence, clinical significance and toxicity of this practice is reviewed, using illustrative cases from a series of 48 NBA consumers. It was found that 10-15% of alcoholics hospitalized in detoxication units have consumed NBA; half of these patients are regular consumers. Addiction to NBA itself may occur. Its use is primarily related to easy accessibility, rather than social or monetary factors. Polydrug misuse and antisocial personality disorder are more frequent in NBA users, but use is not pathognomic of end-stage alcoholism. The 48 NBA users reported surprisingly few toxic symptoms from acute ingestion, perhaps because tolerance to some substances in NBA may occur. Isopropyl alcohol was the exception, reproducibly causing symptoms suggestive of severe gastritis.

    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

    With the increasing availability of alcohol in modern times, the child neglect and abuse portrayed in Hogarth's engraving Gin Lane may once again be witnessed. Reports occur occasionally of alcohol being given deliberately to infants to quieten them, but alcohol poisoning in the slightly older child is not uncommon. The introduction of child-proof containers has altered poisoning figures recently. However, alcohol poisoning tends to occur at ages 3 and 4, that is, about 2 years after the peak of all poisonings in children. This difference may be an indication that alcohol is taken in imitation of parents' drinking, a suggestion which has some support from reported cases of mouthwash poisoning. Holidays and high days where children and alcohol mix, are potentially dangerous periods. Since alcohol poisoning can be fatal, yet if recognised is relatively easily managed, every child with the slightest degree of drowsiness should be suspect until proven or not by blood alcohol. The prevention of alcohol poisoning in the young child consists in protecting the alcohol by lock and key, not setting an example by drinking or gargling in front of children. Many substances such as mouthwash and perfume should also be under supervision. Once actual poisoning has occurred blood sugar is probably more important than the level of blood ethanol and blood sugar levels should be monitored frequently and the child treated with glucose, preferably intravenously.

  13. A Comparison of Modifications to MELCOR versions 1.8.2 and 1.8.6 for ITER Safety Analysis

    2010-06-01

    During the Engineering Design Activity of the International Thermonuclear Experimental Reactor (ITER), the MELCOR 1.8.2 code was selected as one of several codes to be used to perform ITER safety analyses [1]. MELCOR was chosen because it has the capability of predicting coolant pressure, temperature, mass flow rate, and radionuclide and aerosol transport in nuclear facilities and reactor cooling systems. MELCOR can also predict structural temperatures (e.g. first wall, blanket, divertor, and vacuum vessel) resulting from energy produced by radioactive decay heat and/or chemical reactions (oxidation). The Idaho National Laboratory (INL) Fusion Safety Program (FSP) made fusion specific modifications to the MELCOR 1.8.2 code [2-6], including models for water freezing, air condensation, beryllium, carbon, and tungsten oxidation in steam and air environments, flow boiling in coolant loops, and radiation in enclosures, that allowed MELCOR to assess the thermal hydraulic response of ITER cooling systems and the transport of radionuclides as aerosols during accident conditions. Recently, the ITER International Organization (IO) used a “pedigreed” version of MELCOR 1.8.2 [7] to perform accident analyses for ITER’s “Rapport Préliminaire de Sûreté” (Report Preliminary on Safety - RPrS). The MELCOR thermal-hydraulics code [8] is currently under development at the Sandia National Laboratory (SNL) for the US Nuclear Regulatory Commission (NRC). MELCOR is used to model the progression of severe accidents in light water fission reactors. Because MELCOR has undergone many improvements between version 1.8.2 and 1.8.6, the INL FSP decided to introduce fusion modifications into MELCOR 1.8.6, and thereby produce a version of MELCOR 1.8.6 with similar capabilities to the pedigreed version of MELCOR 1.8.2 used for the ITER RPrS. We have applied this version of MELCOR 1.8.6 to the same set of problems used in the MELCOR 1.8.2 pedigree analysis [7]. Section 2 describes a non

    Although the association between alcohol and pancreatic diseases has been recognized for a long time, the impact of alcohol consumption on pancreatitis and pancreatic cancer (PC) remains poorly defined. Nowadays there is not consensus about the epidemiology and the beverage type, dose and duration of alcohol consumption causing these diseases. The objective of this study was to review the epidemiology described in the literature for pancreatic diseases as a consequence of alcoholic behavior trying to understand the association between dose, type and frequency of alcohol consumption and risk of pancreatitis and PC. The majority of the studies conclude that high alcohol intake was associated with a higher risk of pancreatitis (around 2.5%-3% between heavy drinkers and 1.3% between non drinkers). About 70% of pancreatitis are due to chronic heavy alcohol consumption. Although this incidence rate differs between countries, it is clear that the risk of developing pancreatitis increases with increasing doses of alcohol and the average of alcohol consumption vary since 80 to 150 g/d for 10-15 years. With regard to PC, the role of alcohol consumption remains less clear, and low to moderate alcohol consumption do not appear to be associated with PC risk, and only chronic heavy drinking increase the risk compared with lightly drinkers. In a population of 10%-15% of heavy drinkers, 2%-5% of all PC cases could be attributed to alcohol consumption. However, as only a minority (less than 10% for pancreatitis and 5% for PC) of heavily drinkers develops these pancreatic diseases, there are other predisposing factors besides alcohol involved. Genetic variability and environmental exposures such as smoking and diet modify the risk and should be considered for further investigations. PMID:23429423

    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 families with an alcoholic member are twice those for families without one, and up to half of all emergency room admissions are alcohol related. Fetal alcohol syndrome is one of the top three known causes of birth defects, and is totally preventable. Alcohol abuse and alcoholism are estimated to have cost the nation $117 billion in 1983, while nonalcoholic drug abuse that year cost $60 billion. Costs of alcohol abuse are expected to be $136 billion a year by 1990, mostly from lost productivity and employment. Between 6 and 7 million workers are alcoholic, with an undetermined loss of productivity, profits, and competitiveness of American business. Alcohol abuse contributes to the high health care costs of the elderly beneficiaries of Federal health financing programs. Heavily affected minorities include blacks, Hispanics, and Native Americans. Society tends to treat the medical and social consequences of alcohol abuse, rather than its causes. Although our experience with the consequences of alcohol abuse is greater than that for any other drug, public concern for its prevention and treatment is less than for other major illnesses or abuse of other drugs.

    The copolymerization of vinyl alcohol with a number of electron deficient olefins is reported. Vinyl alcohol was formed through the acid catalyzed hydrolysis of ketene methyl vinyl acetal. Under water starved conditions, the kinetics of tautomerization have a zero order dependence upon the concentration of vinyl alcohol (k{sub obs} = 3.5 x 10{sup -6} M/s). Hence, under these conditions, the half life of vinyl alcohol can be several hours at room temperature. We found that this meta-stable species could be quantitatively polymerized in a copolymerization (AIBN, h{upsilon}, -10 to 25{degrees}C) with maleic anhydride, maleimide or acrylonitrile.

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

It examines sectors in Indiana which will impact or be impacted upon by the fuel alcohol industry. The study describes fuel alcohol technologies that could be pertinent to Indiana and also looks closely at how such a fuel alcohol industry may affect the economic and policy development of the State. Finally, the study presents options for Indiana, taking into account the national context of the developing fuel alcohol industry which, unlike many others, will be highly decentralized and more under the control of the lifeblood of our society - the agricultural community.

    The production of alcohol fuel from biomass represents a fast and practical means of adding to the dwindling petroleum supply. The biomass feed-stocks which will feed the alcohol distilleries must be carefully selected. Using food chain biomass crops for conversion to alcohol will cause a reduction in the amount of food available and increase the cost of food and alcohol feedstocks. The food chains should not be drastically interrupted, and agricultural economic balances should not be altered. Various alternatives to alcohol production are presented, which lie within the confines of selected biomass feedstocks and will not interrupt normal agricultural activities. A corn processing and distillation process is shown graphically as an example; the biomass to alcohol conversion potential of feedstocks is given, and the potential cropland for conversion in the U.S.A. is shown as a percentage of the nation's total land area.

    Perfluoroalkyl- and polyfluoroalkyl-substances (PFAS) have been detected in many types of environmental media and biota including humans. We determined volatile PFAS, including fluorotelomer alcohols (FTOHs), fluorotelomer acrylates (FTACs), perfluorooctane sulfonamides (FOSAs), and perfluorooctane sulfonamidoethanols (FOSEs), in indoor air of residences and schools in Germany. FTOHs, FTACs, FOSEs, and FOSAs were quantified with median levels in schools (in residences) of 11,783pg/m(3) (13,198pg/m(3)), 737pg/m(3) (450pg/m(3)), 130pg/m(3) (278pg/m(3)), and 243pg/m(3) (110pg/m(3)), respectively. Using our data and previously published results in a simplified model based on the medians and 95th percentiles, the "typical" and "high" daily non-dietary exposures were calculated to be 4.2ng/kg body weight (9.9ng/kgb.w.) for Σ-FTOHs and 0.1ng/kgb.w. (0.8ng/kgb.w.) for Σ-FOSEs/FOSAs in children. Inhalation was the dominant intake pathway for FTOHs; however, dust ingestion contributed significantly to the total intake of FOSEs/FOSAs. In organisms, 8:2 FTOH is degraded to perfluorooctanoate (PFOA). Assuming that 1% of 8:2 FTOH is converted to PFOA, 8:2 FTOH exposure in Germany has a negligible contribution to the total daily PFOA exposure, which is mainly driven by dietary intake.

    Alcohol dependence constitutes a neuroadaptive state critical for understanding alcoholism, and various methods have been utilized to induce alcohol dependence in animals, one of which is alcohol vapor exposure. Alcohol vapor inhalation provides certain advantages over other chronic alcohol exposure procedures that share the ultimate goal of producing alcohol dependence in rats. Chronic alcohol vapor inhalation allows the experimenter to control the dose, duration, and pattern of alcohol exposure. Also, this procedure facilitates testing of somatic and motivational aspects of alcohol dependence. Chronic exposure to alcohol vapor produces increases in alcohol-drinking behavior, increases in anxiety-like behavior, and reward deficits in rats. Alcohol vapor inhalation as a laboratory protocol is flexible, and the parameters of this procedure can be adjusted to accommodate the specific aims of different experiments. This unit describes the options available to investigators using this procedure for dependence induction, when different options are more or less appropriate, and the implications of each.

    PubMed Central

    Kril, Jillian J.

    2015-01-01

    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

  8. Calcium isotopes in caves as a proxy for aridity: Modern calibration and application to the 8.2 kyr event

    NASA Astrophysics Data System (ADS)

    Owen, R. A.; Day, C. C.; Hu, C.-Y.; Liu, Y.-H.; Pointing, M. D.; Blättler, C. L.; Henderson, G. M.

    2016-06-01

    We present the first study of Ca isotope cycling in a natural cave system, with measurements of bedrock, dripwater and recently formed carbonate, coupled to a first stalagmite time-series spanning the 8.2 kyr event. Dripwaters at Heshang Cave (Central China; 30°27‧N, 110°25‧E) are isotopically heavy relative to the dolomite bedrock, the result of prior calcite precipitation (PCP) occurring earlier in the drip flow path. A simple Rayleigh fractionation model quantifies the extent of PCP in the modern environment at 36% Ca removal. The observed in situ calcium isotope fractionation factor between dripwater and carbonate is Δ 44 / 42 Ca = - 0.63 ± 0.03 ‰ and does not vary during the annual cycle. Measurements of speleothem carbonate spanning the 8.2 kyr event show the response of Ca isotopes to changing climate. δ44/42Ca increases by 0.35‰ at the onset of the event, coeval with changes in δ18O and Mg/Ca, and remains high for 80 yr. This change is explained by decreased rainfall leading to increased PCP; an interpretation supported by established PCP proxies (Mg/Ca, Sr/Ca and Ba/Ca). Ca isotopes indicate that PCP increased to 60% Ca removal during the event, which, from application of a simple box model, suggests mean annual rainfall decreased by approximately a third in Central China during the 8.2 kyr event. The response of Ca isotopes across this event demonstrates their potential for the assessment of past conditions, including past dripwater flow rates and rainfall.

  9. Alcohol, athletic performance and recovery.

    PubMed

    Vella, Luke D; Cameron-Smith, David

    2010-08-01

    Alcohol consumption within elite sport has been continually reported both anecdotally within the media and quantitatively in the literature. The detrimental effects of alcohol on human physiology have been well documented, adversely influencing neural function, metabolism, cardiovascular physiology, thermoregulation and skeletal muscle myopathy. Remarkably, the downstream effects of alcohol consumption on exercise performance and recovery, has received less attention and as such is not well understood. The focus of this review is to identify the acute effects of alcohol on exercise performance and give a brief insight into explanatory factors. PMID:22254055

  10. Alcohol Use and Firearm Violence.

    PubMed

    Branas, Charles C; Han, SeungHoon; Wiebe, Douglas J

    2016-01-01

    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.

  11. Proalcohol: the Brazilian alcohol program

    Examines the Brazilian National Alcohol Plan - Proalcohol - which has as its immediate aim, 20% replacement of all gasoline with alcohol. Future plans call for replacement of virtually all gasoline by alcohol and a significant fraction of diesel fuels by 1986. Issues which are looked at separately are: agronomic, industrial (alcohol production), utilization, institutional, social, environmental, and scientific. Economic issues pervade all of these and are considered in the conclusions. There is a brief discussion of methanol production and the lessons for the United States.

    2000-04-01

    In Switzerland in large companies alcohol prevention programmes are wide spread. Their basic aim is to reduce hidden costs and to improve security at the workplace. To reach these goals early detection of employees with alcohol problems has been introduced and referral systems to therapeutic measures have been developed. Many of the alcohol prevention programmes, however, do not meet the standards of good practice discussed in this article. In addition, the cost efficiency of these programmes could rarely be proved. A noticeable lack of alcohol prevention programmes exists, however, in small and medium companies.

  14. Timing and duration of climate variability during the 8.2 ka event reconstructed from four speleothems from Germany

    The most prominent climate anomaly of the Holocene is the 8.2 ka event, which reflects the impact of a dramatic freshwater influx into the North Atlantic during an interglacial climate state. Thus, it can be considered as a possible analogue for future climate change. Due to the short-lived nature of the event (160.5 ± 5.5 years; Thomas et al., 2007), a detailed investigation requires archives of both high temporal resolution and accurate chronology. We present high-resolution stable oxygen and carbon isotope (ca. 3-4 years) as well as sub-annually resolved trace element records of the 8.2 ka event from stalagmites (BB-3, Bu4, HLK2 and TV1) from three cave systems in Germany (Blessberg Cave, Bunker Cave and Herbstlabyrinth). The location of these caves in central European is well suited in order to detect changes in temperature and precipitation in relation to changes in the North Atlantic region (Fohlmeister et al., 2012). The 8.2 ka event is clearly recorded as a pronounced negative excursion in the δ18O values of all four speleothems. While stalagmites BB-3 from Blessberg Cave and Bu4 from Bunker Cave also show a negative excursion in the δ13C values during the event, the two speleothems from Herbstlabyrinth show no distinctive features in their δ13C values. The timing, duration and structure of the event differ between the individual records. In BB-3, the event occurs earlier (ca. 8.4 ka) and has a relatively short duration of ca. 90 years. In Bu4, the event occurs later (ca. 8.1 ka) and shows a relatively long duration of more than 200 years. In the two speleothems from the Herbstlabyrinth, the event is replicated and has a timing between 8.3 and 8.1 ka and a duration of ca. 150 years. These differences may at least in part be related to the dating uncertainties of 100-200 years (95 % confidence limits).

    1986-08-01

    One of every eight American children is the child of a parent who has a past or present drinking problem. Children of alcoholic parents are at great risk. They are significantly more likely to develop addiction problems and a variety of mental health disorders. They live in homes with high levels of stress. Poor communication, permissiveness, undersocialization, neglect, and violence are common and can be truly devastating. Because of the stigma and denial associated with chemical dependency, these children often suffer in silence, unidentified and unassisted.

    Objective Alcohol expectancies are developed, in part, through exposure to health messages, the understanding of which may be influenced by health literacy. This study explores the relationships among health literacy, alcohol expectancies, and alcohol use behaviors in teens. Methods We studied alcohol use behaviors in the past six months in youths aged 14–19 recruited from two adolescent medicine clinics. We assessed covariate-adjusted bivariate relationships between HL, expectancies, and four measures of alcohol use and tested health literacy as a moderator of the relationship between expectancies and use. Results Of the 293 study teens, 45 percent reported use of alcohol in the past six months. Use behaviors were positively associated with higher health literacy and positive expectancies. Our moderation model suggested that health literacy moderates the relationship between expectancies and use, with the expectancy/use relationship being significantly stronger in higher literacy teens. Conclusion Findings suggest that health literacy can influence alcohol expectancies and behaviors. Practice implications: Health literacy should be explicitly considered in the design of alcohol prevention messages. PMID:25085549

  8. Caffeinated Alcoholic Beverages - An Emerging Trend in Alcohol Abuse.

    2013-08-20

    Alcohol use disorders are pervasive in society and their impact affects quality of life, morbidity and mortality, as well as individual productivity. Alcohol has detrimental effects on an individual's physiology and nervous system, and is associated with disorders of many organ and endocrine systems impacting an individual's health, behavior, and ability to interact with others. Youth are particularly affected. Unfortunately, adolescent usage also increases the probability for a progression to dependence. Several areas of research indicate that the deleterious effects of alcohol abuse may be exacerbated by mixing caffeine with alcohol. Some behavioral evidence suggests that caffeine increases alcohol drinking and binge drinking episodes, which in turn can foster the development of alcohol dependence. As a relatively new public health concern, the epidemiological focus has been to establish a need for investigating the effects of caffeinated alcohol. While the trend of co-consuming these substances is growing, knowledge of the central mechanisms associated with caffeinated ethanol has been lacking. Research suggests that caffeine and ethanol can have additive or synergistic pharmacological actions and neuroadaptations, with the adenosine and dopamine systems in particular implicated. However, the limited literature on the central effects of caffeinated ethanol provides an impetus to increase our knowledge of the neuroadaptive effects of this combination and their impact on cognition and behavior. Research from our laboratories indicates that an established rodent animal model of alcoholism can be extended to investigate the acute and chronic effects of caffeinated ethanol. PMID:25419478

    Purpose An update on pharmacotherapy for achieving and maintaining abstinence and mitigating hepatic damage in patients with alcoholic liver disease (ALD) is presented. Summary Currently there are limited pharmacotherapy options for managing ALD, which encompasses a broad spectrum of disorders ranging from steatosis and alcoholic hepatitis to fibrosis, cirrhosis, and hepatocellular cancer. Individual variation in the severity, presentation, and complex pathologenesis of ALD defines barriers to effective treatment. Scoring of disease severity using validated assessment instruments should guide treatment approaches; abstinence and proper nutrition continue to be the cornerstones of management. A literature search (through December 31, 2013) identified no reports of randomized controlled trials using Food and Drug Administration (FDA)-approved medications for the treatment of alcohol dependence in ALD-spectrum disorders. Disulfiram, acamprosate, and naltrexone (oral and intramuscular), while approved by FDA for treatment of alcohol dependence, are not currently approved for use in patients with ALD. Baclofen (also not FDA-approved for use in ALD) is the only medication available in the United States with demonstrated safety and efficacy in reducing alcoholic behavior that has been formally tested in clinical trials in patients with ALD. Pharmacotherapy of alcoholic hepatitis using glucocorticoids or pentoxifylline has shown promise, but these options are reserved for severe ALD only. Conclusion Although various treatments have been investigated for ALD in patients with alcoholism, complete abstinence from alcohol is currently the only recommended form of hepatoprotection for the entire spectrum of ALD diagnoses.

    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

  13. Green mosses date the Storegga tsunami to the chilliest decades of the 8.2 ka cold event

    Chlorophyll in dead plants ordinarily decomposes completely before permanent burial through exposure to light, water and oxygen. Here we describe 8000-year-old terrestrial mosses that retain several percent of its original chlorophyll. The mosses were ripped of the land surface, carried 50-100 m off the Norwegian coast of the time, and deposited in depressions on the sea floor by the Storegga tsunami. A little of the chlorophyll survived because, within hours after entraining it, the tsunami buried the mosses in shell-rich sediments. These sediments preserved the chlorophyll by keeping out light and oxygen, and by keeping the pH above 7—three factors known to favour chlorophyll's stability. Because the green mosses were buried alive, their radiocarbon clock started ticking within hours after the Storegga Slide had set off the tsunami. Radiocarbon measurement of the mosses therefore give slide ages of uncommon geological precision, and these, together with a sequence of ages above and below the boundary, date the Storegga Slide to the chilliest decades of the 8.2 ka cold event at 8120-8175 years before AD 1950. North Atlantic coastal- and fjord- climatic records claimed to show evidence of the 8.2 cold event should be carefully examined for possible contamination and disturbance from the Storegga tsunami.

    Maternal alcohol use during pregnancy is prevalent, with as many as 12% of pregnant women consuming alcohol. Alcohol intake may vary from an occasional drink, to weekly binge drinking, to chronic alcohol use throughout pregnancy. Whereas there are certain known consequences from fetal alcohol exposure, such as fetal alcohol syndrome, other effects are less well defined. Craniofacial dysmorphologies, abnormalities of organ systems, behavioral and intellectual deficits, and fetal death have all been attributed to maternal alcohol consumption. This review article considers the theoretical mechanisms of how alcohol affects the fetus, including the variable susceptibility to fetal alcohol exposure and the implications of ethanol dose and timing of exposure. Criteria for diagnosis of fetal alcohol syndrome are discussed, as well as new methods for early detection of maternal alcohol use and fetal alcohol exposure, such as the use of fatty acid ethyl esters. Finally, current and novel treatment strategies, both in utero and post utero, are reviewed.

    Introduction Stronger alcohol policies predict decreased alcohol consumption and binge drinking in the United States. We examined the relationship between the strength of states’ alcohol policies and alcoholic cirrhosis mortality rates. Methods We used the Alcohol Policy Scale (APS), a validated assessment of policies of the 50 US states and Washington DC, to quantify the efficacy and implementation of 29 policies. State APS scores (theoretical range, 0–100) for each year from 1999 through 2008 were compared with age-adjusted alcoholic cirrhosis death rates that occurred 3 years later. We used Poisson regression accounting for state-level clustering and adjusting for race/ethnicity, college education, insurance status, household income, religiosity, policing rates, and urbanization. Results Age-adjusted alcoholic cirrhosis mortality rates varied significantly across states; they were highest among males, among residents in states in the West census region, and in states with a high proportion of American Indians/Alaska Natives (AI/ANs). Higher APS scores were associated with lower mortality rates among females (adjusted incidence rate ratio [IRR], 0.91 per 10-point increase in APS score; 95% confidence interval [95% CI], 0.84–0.99) but not among males (adjusted IRR, 0.97; 95% CI, 0.90–1.04). Among non-AI/AN decedents, higher APS scores were also associated with lower alcoholic cirrhosis mortality rates among both sexes combined (adjusted IRR, 0.89; 95% CI, 0.82–0.97). Policies were more strongly associated with lower mortality rates among those living in the Northeast and West census regions than in other regions. Conclusions Stronger alcohol policy environments are associated with lower alcoholic cirrhosis mortality rates. Future studies should identify underlying reasons for racial/ethnic and regional differences in this relationship. PMID:26469950

    This article describes the role played by a patient's mental competency in the assessment and treatment of patients who are under the influence of alcohol and expressing suicidal thoughts. The factors that should be taken into consideration in the assessment of suicidality are not always clear: somatic complications or possible discharge from the emergency room. The treating physician at the emergency department should evaluate the mental competency. The risk of suicide should also be assessed by a psychiatrist. In order to make the right decisions about treatment and mental competency, the key concepts of proportionality, effectiveness and subsidiarity in the assessment of mental competency are crucial. These concepts require a personalized, multidisciplinary approach and result in unique decisions which may differ from case to case. In the assessment and treatment of patients under the influence of alcohol who are suicidal and do not want to have a proper medical evaluation, communication between the emergency physician, internist and psychiatrist is crucial to optimize both evaluation and treatment. In this context, tasks and responsibilities should be clearly defined in order to minimize the risk of errors and complications. PMID:26443116

    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.

    When a drop impacts a flat surface of the same liquid at an intermediate velocity, the impact can result in the formation of a very large number of very small bubbles. At lower velocities, drops bounce or float, and at larger velocities a single bubble forms, or there is a splash. The formation of large numbers of small bubbles during intermediate velocity impacts is termed Mesler entrainment and its controlling mechanism is poorly understood. Existing research has shown that Mesler entrainment is highly irreproducible when water is the working fluid, and very reproducible when silicone oil is the working fluid. Whether this is because water is problematic, or silicone oil is uniquely well-suited, is unclear. To answer this question, experiments were conducted using three different alcohols. The results of these experiments were very reproducible for all alcohols tested, suggesting that there is something unique about water which accounts for its lack of reproducibility. The data from these experiments were also used to develop a dimensionless group that quantifies the conditions under which Mesler entrainment occurs. This dimensionless group is used to provide insight into the mechanism of this unique method of bubble formation.

    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.

    Background This study examined the effect of fathers’ alcoholism and associated risk factors on toddler compliance with parental directives at 18 and 24 months of age. Methods Participants were 215 families with 12-month-old children, recruited through birth records, who completed assessments of parental substance use, family functioning, and parent-child interactions at 12, 18, and 24 months of child age. Of these families, 96 were in the control group, 89 families were in the father-alcoholic-only group, and 30 families were in the group with two alcohol-problem parents. Child compliance with parents during cleanup situations after free play was measured at 18 and 24 months. The focus of this paper is on four measures of compliance: committed compliance, passive noncompliance, overt resistance, and defiance. Results Sons of alcohol-problem parents exhibited higher rates of noncompliance compared with sons of nonalcoholic parents. Sons in the two-alcohol-problem parent group seemed to be following a trajectory toward increasing rates of noncompliance. Daughters in the two-alcohol-problem parent group followed an opposite pattern. Other risk factors associated with parental alcohol problems also predicted compliance, but in unexpected ways. Conclusions Results indicate that early risk for behavioral undercontrol is present in the toddler period among sons of alcoholic fathers, but not among daughters. PMID:11707637

    SUMMARY The number of Americans who are overweight or obese has reached epidemic proportions. Elevated weight is associated with health problems and increased medical expenditures. This paper analyzes Waves 1 and 2 of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC) to investigate the role of alcohol consumption in weight gain. Alcohol is not only an addictive substance but also a high-calorie beverage that can interfere with metabolic function and cognitive processes. Because men and women differ in the type and amount of alcohol they consume, in the biological effects they experience as a result of alcohol consumption, and in the consequences they face as a result of obesity, we expect our results to differ by gender. We use first-difference models of body mass index (BMI) and alcohol consumption (frequency and intensity) to control for time-invariant unobservable factors that may influence changes in both alcohol use and weight status. Increasing frequency and intensity of alcohol use is associated with statistically significant yet quantitatively small weight gain for men but not for women. Moreover, the first-difference results are much smaller in magnitude and sometimes different in sign compared to the benchmark pooled cross-sectional estimates. PMID:19548203

    A significant amount of neurobiological research regarding the development of alcohol use disorders (AUDs) has focused on alcohol-related activation and long-term alterations in the mesocortical dopaminergic reward pathways. However, alcohol does not only interact with brain reward systems. Many of its acute and chronic effects may be related to allostatic adaptations in hypothalamic and extrahypothalamic stress regulation pathways. For example, acute binge intoxication is associated with hypothalamically driven increases in blood cortisol, norepinephrine, and sex steroid metabolite levels. This may contribute to the development of mesocortical sensitization to alcohol. Furthermore, chronic alcohol exposure is associated with systemic dysregulation of the hypothalamic pituitary adrenal axis, sympathetic adrenal medullary system, and sex steroid systems. This dysregulation appears to manifest as neuroendocrine tolerance. In this review, we first summarize the literature suggesting that alcohol-induced alterations in these hypothalamic systems influence craving and contribute to the development of AUDs. We note that for women, the effects of alcohol on these neuroendocrine stress regulation systems may be influenced by the rhythmic variations of hormones and steroids across the menstrual cycle. Second, we discuss how changes in these systems may indicate progression of AUDs and increased risk of relapse in both sexes. Specifically, neuroendocrine tolerance may contribute to mesocortical sensitization, which in turn may lead to decreased prefrontal inhibitory control of the dopaminergic reward and hypothalamic stress systems. Thus, pharmacological strategies that counteract alcohol-associated changes in hypothalamic and extrahypothalamic stress regulation pathways may slow the development and progression of AUDs.

  16. WHAT PSYCHIATRISTS THINK ABOUT ALCOHOLISM

    The one approach most favored for alcoholism by psychiatrists in Southern California who answered a questionnaire is membership in Alcoholics Anonymous. Ninety-nine per cent of them approved Alcoholics Anonymous, and 80 per cent had referred patients to the organization. Yet they believed only 10 per cent of the persons who join A.A. remain sober for over two years. This against the claim of A.A. that 60 per cent or more of their fellowship are recovered emphasized the pessimism of the psychiatrists questioned. Ninety per cent of the psychiatrists who replied said they do not treat alcoholics or that they limit the number or the type they will accept for treatment. They obtain recovery, they said, of 10 per cent of patients, improvement of 50 per cent, and the rest are unchanged. The emphasis in psychiatry is on elimination of the anxieties leading to alcoholism; in Alcoholics Anonymous the emphasis is on the strength to bear these anxieties. Ninety per cent of the replies received were in favor of clinics for alcoholics, and the respondents felt that governmental agencies should support these clinics. Under such circumstances psychiatrists would combine their abilities with psychologists, social workers and Alcoholics Anonymous. Thirty-five per cent of psychiatrists said they are willing to work in a clinic, the majority without recompense. PMID:13270110

    Alcohol is recognized as a direct hepatotoxin, but the precise molecular pathways that are important for the initiation and progression of alcohol-induced tissue injury are not completely understood. The current understanding of alcohol toxicity to organs suggests that alcohol initiates injury by generation of oxidative and nonoxidative ethanol metabolites and via translocation of gut-derived endotoxin. These processes lead to cellular injury and stimulation of the inflammatory responses mediated through a variety of molecules. With continuing alcohol abuse, the injury progresses through impairment of tissue regeneration and extracellular matrix (ECM) turnover, leading to fibrogenesis and cirrhosis. Several cell types are involved in this process, the predominant being stellate cells, macrophages, and parenchymal cells. In response to alcohol, growth factors and cytokines activate many signaling cascades that regulate fibrogenesis. This mini-review brings together research focusing on the underlying mechanisms of alcohol-mediated injury in a number of organs. It highlights the various processes and molecules that are likely involved in inflammation, immune modulation, susceptibility to infection, ECM turnover and fibrogenesis in the liver, pancreas, and lung triggered by alcohol abuse.

    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).
