Social influences together with local cultural norms are central factors that can influence the use of alcohol. The study, therefore, identified socio-cultural norms and roles capable of influencing alcohol use among young people in an alcohol producing community, in Nigeria. We used qualitative technique - focused group discussions among selected key persons in the area of study. Three groups; adult males, adult females and youths were engaged in discussions around the themes of socio-cultural; norms, roles, beliefs, values and practices that influences alcohol abuse...

BACKGROUND: Alcohol consumption has frequently been purported as a driver of condomless sex and HIV transmission, but to date, experimental evidence for the causal risk-taking impact of alcohol among HIV-positive populations is lacking. The present experiment sought to determine whether acute alcohol consumption has a direct causal impact on condomless sex intentions among HIV-positive men-who-have-sex-with-men (MSM), and to assess whether alcohol's impact differs between MSM who are HIV-positive versus HIV-negative...

Several investigations have revealed that liver diseases exhibit gender biases, but identifying the root causes of such biases has been challenging. Evidence of gender differences in liver function is present from the early stage of embryonic development. The differences in access to care and treatment as well as diagnostic deliberation may affect gender-specific differences in liver disease progression. Apart from the pathogenesis, xenobiotic metabolism, immune responses, gene expressions, mitochondrial function, lipid composition, and enzyme activities also differ in this sexually dimorphic organ...

A highly efficient regio- and enantioselective monohydrogenation of 1,4-dienes has been realized using an iridium catalyst with a chiral N,P-ligand under mild conditions. The substrate scope was studied and included both unfunctionalized as well as functionalized substituents on the meta- or para-position. Substrates having substituents with functionalities such as silyl protected alcohols or ketals were monohydrogenated in high regioselectivity and high enantiomeric excess (up to 98% ee).

Growing concern with the environmental impact of CO2 emissions produced by combustion of fuels derived from fossil-based carbon resources has stimulated the search for renewable sources of carbon. Much of this focus has been on the development of methods for producing transportation fuels, the major source of CO2 emissions today, and to a lesser extent on the production of lubricants and chemicals. First-generation biofuels such as bioethanol, produced by the fermentation of sugar cane- or corn-based sugars, and biodiesel, produced by the transesterification reaction of triglycerides with alcohols to form a mixture of long-chain fatty esters, can be blended with traditional fuels in limited amounts and also arise in food versus fuel debates...

Adipose tissue represents a large volume of biologically active tissue that exerts substantial systemic effects in health and disease. Alcohol consumption can profoundly disturb the normal functions of adipose tissue by inducing adipocyte death and altering secretion of adipokines, pro-inflammatory mediators and free fatty acids from adipose tissue, which have important direct and indirect effects on the pathogenesis of alcoholic liver disease (ALD). Cessation of alcohol intake quickly reverses inflammatory changes in adipose tissue, and pharmacological treatment that normalizes adipose tissue function improves experimental ALD...

Esophageal cancer (EC) is the eighth most common cancer and is the sixth leading cause of death worldwide. The incidence of histologic subtypes of EC, esophageal adenocarcinoma (EAC) and esophageal squamous carcinoma (ESCC), display considerable geographic variation. EAC arises from metaplastic Barrett's esophagus (BE) in the context of chronic inflammation secondary to exposure to acid and bile. The main risk factors for developing ESCC are cigarette smoking and alcohol consumption. The main somatic genetic abnormalities showed a different genetic landscape in EAC compared to ESCC...

Maternal obesity predisposes offspring to metabolic dysfunction and Non-Alcoholic Fatty Liver Disease (NAFLD). Melanocortin-4 receptor (Mc4r)-deficient mouse models exhibit obesity during adulthood. Here, we aim to determine the influence of the Mc4r gene on the liver of mice subjected to perinatal diet-induced obesity. Female mice heterozygous for Mc4r fed an obesogenic or a control diet for 5 weeks were mated with heterozygous males, with the same diet continued throughout pregnancy and lactation, generating four offspring groups: control wild type (C_wt), control knockout (C_KO), obese wild type (Ob_wt), and obese knockout (Ob_KO)...

Liver cancer is the second most common cause of cancer-related death. The major forms of primary liver cancer are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). Both these tumors develop against a background of cirrhotic liver, non-alcoholic fatty liver disease, chronic liver damage and fibrosis. HCC is a heterogeneous disease which usually develops within liver cirrhosis related to various etiologies: hepatitis B virus (HBV) infection (frequent in Asia and Africa), hepatitis C virus (HCV), chronic alcohol abuse, or metabolic syndrome (frequent in Western countries)...

Terra firma-forme dermatosis (TFFD) is a clinical condition characterized by brown-gray, velvety, pigmented patches or plaques, resembling dirt on the skin. Nevoid acanthosis nigricans (NAN) is a rare and recently described form of acanthosis nigricans occurring during childhood or early adulthood. Herein we describe a patient with TFFD, initially misdiagnosed as NAN. The patient had developed hyperkeratotic and hyperpigmented plaques on and around the umbilicus during pregnancy. Though regular in bathing practices, she could not clear away the lesions and concerned marks for inesthetic appearance...

OBJECTIVE: South Africa's Western Cape Province has one of the highest rates of fetal alcohol spectrum disorder globally. Alcohol-serving venues are likely important sites to identify women at high risk of having a child with fetal alcohol spectrum disorder. The goal of this study was to examine the risk for alcohol-exposed pregnancies among women who drink in alcohol-serving venues. METHOD: Cross-sectional surveys were conducted with 200 women of reproductive age at seven drinking venues in a single Cape Town community...

OBJECTIVE: Given the controversy surrounding the question of whether there are direct or causal effects of exposure to maternal smoking during pregnancy (SDP) on offspring outcomes such as substance use during the adolescent years, we sought to test, on a preliminary basis, within- and between-family associations of SDP and initiation of substance use early in adolescence (by age 15 years) using a discordant sibling design. METHOD: We used a sibling-comparison approach in a sample of 173 families drawn from the state of Missouri, wherein mothers were discordant for smoking behaviors between two different pregnancies, to test for associations of SDP and initiation of substance use in a younger adolescent cohort...

OBJECTIVE: There is concern that changes in marijuana-related policy and public opinion may lead to increased access to marijuana among young people in the United States. However, little research has been conducted on changes in youth's perceptions of marijuana access, and studies have yet to systematically examine trends in perceived access across key sociodemographic and externalizing behavioral subgroups. METHOD: Using population-based data collected between 2002 and 2015 as part of the National Survey on Drug Use and Health, we examined trends in perceived marijuana access among non-Hispanic White, African American, and Hispanic adolescents (ages 12-17, n = 221,412)...

OBJECTIVE: The findings of previous research that examined relationships between popularity and alcohol use in adolescents have been mixed, and few hypotheses have proposed mechanisms for this relationship. The current study expands on previous literature (a) by examining a possible mechanism that can explain the relation between popularity and alcohol use (home access to alcohol) and (b) by using another sociometric measure ("betweenness"), beyond popularity, that may relate more to home alcohol access...

OBJECTIVE: Few studies linking single motherhood and maternal smoking during pregnancy consider correlated risk from problem substance use beyond history of smoking and concurrent use of alcohol. In the present study, we used propensity score methods to examine whether the risk of smoking during pregnancy associated with single motherhood is the result of potential confounders, including alcohol dependence. METHOD: Data were drawn from mothers participating in a birth cohort study of their female like-sex twin offspring (n = 257 African ancestry; n = 1,711 European or other ancestry)...
