Trait impulsivity and health risk behaviors: A latent profile analysis

Substance use and risky sexual behavior are negative health outcomes associated with the heterogeneous construct of impulsivity and emerging adulthood. The present study appears to be the first to examine how different facets of impulsive personality may be used to depict various profiles that differentially predict engagement in substance use and risky sexual behavior. Specifically, this study extends previous research by providing a comprehensive examination of impulsivity profiles in relation to various health risk outcomes via negative urgency, lack of premeditation, lack of perseverance, sensation seeking, and positive urgency. Participants (N = 599) completed the Short Urgency, Premeditation, Perseverance, Sensation Seeking, and Positive Urgency Scale (SUPPS-P), the Youth Risk Behavior Survey (YRBS), and the Student Sexual Risks Scale (SSRS). Impulsivity profiles were examined using latent profile analysis in which varying degrees of the SUPPS-P facets were grouped together based on participant response patterns. Results of latent profile analyses indicated an optimal 5-profile solution (low total impulsivity, moderate total impulsivity, high lack of premeditation/lack of perseverance facets, moderate positive urgency/negative urgency/sensation seeking facets, high positive urgency/negative urgency/sensation seeking facets).

Societal development and the alcohol-attributable burden of disease

AimThis study aimed to examine if there is an interaction between alcohol use and human development in terms of their associations with alcohol-attributable health harms. DesignStatistical modelling of global country- and region-specific data from 2016. SettingGlobal. Participants/CasesThe units of the analyses were countries (n = 180) and regions (n = 4) based on their Human Development Index (HDI). MeasurementsAlcohol-attributable harms [deaths, years of life lost (YLL), years lived with disability (YLD) and disability-adjusted life years (DALYs) lost] and risk relations were based on a recent study using World Health Organization (WHO) estimates for 2016. Human development was measured using the HDI, a summary score of life expectancy, education and gross national income from the United Nations Development Programme. Interactions between HDI and adult per-capita consumption (APC) affecting alcohol-attributable harms were assessed using likelihood ratio tests. Differences in alcohol-attributable harms per litre of APC between HDI groups were assessed using regression analyses and a reference group of low HDI. FindingsAPC is associated with alcohol-attributable deaths, YLL, YLDs and DALYs lost, while HDI is associated with alcohol-attributable deaths, YLL and DALYs lost. Statistical analyses indicated there is an interaction between HDI and APC in their associations with alcohol-attributable deaths, YLL and DALYs lost per 100000 people. The alcohol-attributable burden was highest in low HDI countries, with 11.65 [95% confidence interval (CI) = 10.75, 12.40] deaths and 495.61 (95% CI = 461.83, 569.23) DALYs lost per 100000 people per litre of APC, and lowest in very high HDI countries, with 4.15 (95% CI = 2.46, 5.71) deaths and 200.31 (95% CI = 122.78, 265.10) DALYs lost per 100000 people per litre of APC. However, no statistical differences between low and very high HDI groupings for these burdens were observed. ConclusionsThere appears to be an interaction between the Human Development Index and alcohol use in their associations with alcohol-attributable deaths, years of life lost and disability-adjusted life years lost but not with alcohol-attributable years lived with disability. Alcohol appears to have a stronger harmful impact per litre of alcohol consumed in lesser developed countries than in developed countries.

Effects of post-harvest fungal infection of apples on chemical characteristics of cider

The impact of fungal post-harvest infection of apple on the chemical composition of cider was investigated through a comparative analysis of ciders obtained from apples (Gala variety) separately infected by five fungal species (Alternaria alternata, Botrytis cinerea, Diplodia seriata, Monilinia fructigena, and Penicillium expansum) and cider from sound apples. The content of several flavor-active molecules belonging to different chemical groups, such as alcohols, esters, acids, aldehydes, phenols, and lactones, significantly varied among ciders. Particularly, cider from sound apples had a higher concentration of ethyl ester acetate, fatty acid ethyl esters and fatty acids, molecules that contribute to fruity and sweet scent. Principal component analysis well discriminated ciders, evidencing species-specific fungal effect. Differences in precursor availability in juices and biosynthesis pathways in fungi could explain changes in aroma profile of ciders. This study provides information on the potential risk to produce cider from infected apples due to the possible quality depreciation.

The application of headspace gas chromatographic method for the determination of ethyl alcohol in craft beers, wines and soft drinks

The increasing interest of consumers in the still-developing craft beer market and the strict tax-related legal regulations concerning alcoholic beverages require precise methods for quality control. Determination of ethyl alcohol concentration was performed in 167 samples of alcoholic beverages (craft beers, soft drinks, wines, and cider). We applied headspace gas chromatography using a dual column/dual flame ionization detector (HS-GC-FID/FID), a technique routinely used in forensic toxicology. The method was linear in range, from 0.01 to 20.0%, with a coefficient of determination of 0.999 (R2). The limit of quantification was 0.01%; the detection limit was 0.003%. Furthermore, very good validation parameters were achieved (precision and accuracy below 5%). The samples were analyzed for compliance with EU standards and recommendations of The Beer Judge Certification Program. Moreover, the content of trace quantities of volatile compounds and fusel alcohols (1-propanol, 2-propanol, acetone, and acetaldehyde) was found in the majority of alcoholic beverages.

Osmotic dehydration and convective drying of kiwifruit (Actinidia deliciosa) – The influence of ultrasound on process kinetics and product quality

The aim of this study was to assess the impact of ultrasound on two subsequent processes – initial osmotic dehydration and convective drying of kiwifruit (Actinidia deliciosa). The effect of ultrasound (at a frequency of 25 kHz) was assessed both in terms of process kinetics and product quality. During the study, three different osmotic agents were used – erythritol, sorbitol, and sucrose – in an aqueous solution at a concentration of 50% (w/w). The essential kinetic parameters were analyzed – water loss and increase of dry matter during osmotic dehydration, and evolution of moisture content and temperature of samples during convective drying (drying curves). Product quality was assessed on the basis of color, water activity, and content of relevant bioactive components – polyphenols and carotenoids. It was found that the application of ultrasound during osmotic dehydration resulted in higher water loss and solid gain. This surely results from the phenomena occurring during the propagation of the elastic waves in the liquid medium (mainly related to cavitation) and enhancement of the mass transfer. The use of ultrasound during convective drying also had a positive effect on the kinetics of this process. In most cases, during the ultrasonically assisted drying operations, a significant increase in drying rate was observed, leading to a reduction in drying time. This may be due to the intensification of both heat and mass transfer as a result of the mechanical and thermal effects of ultrasound. The assessment of product quality showed that the use of sugar alcohols was a good alternative to sucrose, and ultrasound-assisted convective drying increased the retention of valuable carotenoids and polyphenols. Moreover, in all dried kiwifruit slices, water activity was below 0.6, which can guarantee the microbiological stability of the tested samples.

Sourdough cultures as reservoirs of maltose-negative yeasts for low-alcohol beer brewing

De novo sourdough cultures were here assessed for their potential as sources of yeast strains for low-alcohol beer brewing. NGS analysis revealed an abundance of ascomycete yeasts, with some influence of grain type on fungal community composition. Ten different ascomycete yeast species were isolated from different sourdough types (including wheat, rye, and barley) and seven of these were screened for a number of brewing-relevant phenotypes. All seven were maltose-negative and produced less than 1% (v/v) alcohol from a 12 degrees Plato wort in initial fermentation trials. Strains were further screened for their bioflavouring potential (production of volatile aromas and phenolic notes, reduction of wort aldehydes), stress tolerance (temperature extremes, osmotic stress and ethanol tolerance) and flocculence. Based on these criteria, two species (Kazachstania servazzii and Pichia fermentans) were selected for 10 L-scale fermentation trials and sensory analysis of beers. The latter species was considered particularly suitable for production of low-alcohol wheat beers due to its production of the spice/clove aroma 4-vinylguaiacol, while the former showed potential for lager-style beers due to its clean flavour profile and tolerance to low temperature conditions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 124-76-5 is helpful to your research. Safety of Isoborneol.

Examining the effects of problematic alcohol use on cigarette abstinence in recently diagnosed cancer patients enrolled in a cessation trial: A secondary analysis

Aims: Among people with cancer, dual alcohol and tobacco use increases risk for morbidity and mortality. Most smoking cessation clinical trials with this patient population have excluded individuals with problematic alcohol use. This investigation examined whether problematic alcohol use affects smoking cessation in cancer patients. Methods: Mixed-methods secondary analysis of data from the Smokefree Support Study, a randomized-controlled trial examining the efficacy of Intensive (IT; n = 153) vs. Standard Treatment (ST; n = 150) for smoking cessation in newly diagnosed cancer patients. Problematic alcohol use was assessed at enrollment using the Cut-Down Annoyed-Guilty-Eye-Opener (CAGE), weekly frequency of alcohol use and binge drinking measures. Alcohol use was categorized as: no current alcohol use, moderate and problematic use. The primary outcome was biochemically-confirmed cigarette abstinence at 6-months. A subset of patients (n = 72) completed qualitative exit-interviews. Results: Among all participants, biochemically-confirmed cigarette abstinence rates were 25% (n = 32), 28% (n = 27), and 36% (n = 20) for participants reporting no current alcohol use, moderate use, and problematic use, respectively (p = 0.33). In logistic regression analysis, neither problematic alcohol use (AOR = 0.96, 95% CI = 0.35-2.67, p = .94) nor the problematic use by study arm interaction (AOR = 2.22, 95% CI = 0.59-8.39, p = .24) were associated with biochemically-confirmed 6-month abstinence. Qualitatively, participants reported that drinking alcohol triggers urges to smoke. Conclusion: Newly diagnosed cancer patients reporting problematic alcohol use were not less likely to quit smoking than those without. Additional research is needed to investigate whether problematic alcohol users may benefit from smoking and alcohol behavior change interventions at the time of cancer diagnosis.

Predictors of substance use in a clinical sample of youth seeking treatment for Trauma-related mental health problems

Child maltreatment and traumatic events are well established risk factors for adolescent substance use problems, but little is known about the unique contributions of etiological factors on trauma-exposed youths’ pre-treatment substance use in clinical settings. This study examined associations between substance use and risk and protective factors measured across multiple ecological levels among a unique sample of youth seeking treatment for trauma-related mental health problems in child advocacy centers. Participants were adolescents (N = 135; 85% female; 60% white, 31% black) aged 13-17 years (M = 15.4) with >= 1 experience of child maltreatment or other interpersonal violence, current substance use, and >= 5 PTSD symptoms. Youth and caregivers completed validated questionnaires and clinical interviews at a pre-treatment assessment in a randomized controlled trial of a treatment for co-occurring traumatic stress and substance use. Negative binomial regression models identified different patterns of risk and protective factors for alcohol and cannabis. Clinical implications of these results are discussed, including the potential targets for integrated psychotherapies that address co-occurring substance use and traumatic stress in youth.

Fatty Acids and Flavor Components in the Oil Extracted from Golden Melon Seeds

For complete utilization of raw materials and edible oil production, the oil from golden melon seeds (GSs) is extracted via the cold-pressing, hot-pressing, and ultrasound-assisted aqueous enzymatic extraction (AEE), and the fatty acid composition, and nutritional value of the extracted GS oils (GSOs) are analyzed. The volatile compounds present in the GSOs are determined using gas chromatography-mass spectrometry. The aroma profiles of different GSO samples are further distinguished by using an electronic nose. A total of 16 fatty acids are identified in the GSO samples, with atherogenic, thrombogenic, and nutritive value indices ranging from 0.142-0.151, 0.366-0.403, and 5.019-5.299, respectively. Moreover, 43 volatile compounds, including esters, hydrocarbons, alcohols, ketones, pyrazines, and aldehydes are identified. The cold-pressed GSO presents fresh and fruity flavors, while the hot-pressed GSO presents roasted, nutty, fatty, and fruity flavors, and the GSO obtained via AEE presents fatty and fruity flavors. The acid and peroxide contents of these oil samples are 0.69-079 mg g(-1) and 5.17-5.79 mmol kg(-1), respectively. The results indicate that the extraction method affects the fatty acid composition, flavor components, and physiochemical properties of the GSO. This study may help promote the development of edible GSO. Practical applications: With high demand for edible oils, it is of great significance to find natural edible oils from different sources. The oil in golden melon seeds is extracted by different methods. Their fatty acid composition and flavor components are analyzed. The GSO extracted via AEE method is rich in fatty acids composition. This work would guide the development of an edible GSO and increase the value of golden melon.

Ion transfer channel network formed by flower and rod shape crystals of hair hydrolysate in poly(vinyl alcohol) matrix and its application as anion exchange membrane in fuel cells

Ion transfer phenomena occurring in nature are known to be most efficient. Many efforts have been made to mimic such phenomena, especially in the area of energy transfer. Proteins consisting of various amino acids are known to be the fundamental materials behind these phenomena. In the current study, an effort was made to extract proteinaceous material from human hair bio-waste by a green chemical-free thermal hydrolysis process. A simple heat treatment of the human hairs in presence of water led to the formation of a water soluble material, which was called hair hydrolysate (HH), contains 70 wt% proteinaceous material. It was utilized for the fabrication of poly(vinyl alcohol) (PVA) matrix-based anion exchange membrane (AEM). Presence of 27 wt% charged amino acids and 19 wt% polarizable amino acids in the HH provided effective charge transfer sites. 7 wt% arginine present in the HH, having continuous delocalized net positive charge helped the membrane to be stable in highly alkaline conditions, which was confirmed by an indirect analysis of alkaline stability. Formation of rod and flower shaped crystal morphology by the HH in glutaraldehyde crosslinked PVA matrix, created a continuous channel network at higher loadings, which provided a simple path for ion transfer, achieving OHconductivity of 7.46 mS/cm at 70 degrees C. Swelling of the PVA matrix was minimized by annealing of the HH loaded sample, which resulted in reduction of ionic conductivity to 6.16 mS/cm (at 70 degrees C). At the same time, improvement in the properties like increase in thermal, mechanical and thermo-mechanical stability, reduction in water uptake, %swelling and methanol permeability was observed. The selectivity of the membrane was increased to almost a decimal place. Thus, the HH obtained from simple green thermal hydrolysis of human hair bio-waste is a cheap material, which is found to be suitable as ion conductive material for alkaline fuel cells.
