Shared genetic risk between eating disorder- and substance-use-related phenotypes: Evidence from genome-wide association studies
2020
AbstractEating disorders and substance use disorders frequently co-occur. Twin studies reveal shared genetic variance between liabilities to eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa (BN) and problem alcohol use (genetic correlation [rg], twin-based=0.23-0.53). We estimated the genetic correlation between eating disorder and substance use and disorder phenotypes using data from genome-wide association studies (GWAS). Four eating disorder phenotypes (anorexia nervosa [AN], AN with binge-eating, AN without binge-eating, and a BN factor score), and eight substance-use-related phenotypes (drinks per week, alcohol use disorder [AUD], …
Genome-wide association and genetic functional studies identify autism susceptibility candidate 2 gene (AUTS2) in the regulation of alcohol consumpti…
2011
Alcohol consumption is a moderately heritable trait, but the genetic basis in humans is largely unknown, despite its clinical and societal importance. We report a genome-wide association study meta-analysis of ∼2.5 million directly genotyped or imputed SNPs with alcohol consumption (gram per day per kilogram body weight) among 12 population-based samples of European ancestry, comprising 26,316 individuals, with replication genotyping in an additional 21,185 individuals. SNP rs6943555 in autism susceptibility candidate 2 gene ( AUTS2 ) was associated with alcohol consumption at genome-wide significance ( P = 4 × 10 −8 to P = 4 × 10 −9 ). We found a genotype-specific expression of AUTS2 in 9…
Neuroesteroides y adicción alcohólica
2007
Los neuroesteroides (NE) son esteroides sintetizados de novo en el SNC a partir del colesterol independientemente de las fuentes periféricas. NE como la allopregnanolona (AlloP) actúan como moduladores positivos endógenos del receptor GABAA, acción similar a la del alcohol y que se relaciona con aspectos de la adicción alcohólica como la tolerancia, el síndrome de abstinencia (SAA), o los efectos ansiolíticos. La AlloP sustituye al alcohol en paradigmas de drug discrimination . Este hecho, junto a toda otra serie de pruebas experimentales muestra que los NE participan de manera importante en la adicción alcohólica. El consumo de alcohol provoca un aumento de la concentración de AlloP en pla…
Ursolic acid from the Chinese herb Danshen (Salvia miltiorrhiza L.) upregulates eNOS and downregulates Nox4 expression in human endothelial cells
2007
Danshen, the dried root of Salvia miltiorrhiza Bunge (Lamiaceae), is one of the most commonly used traditional Chinese medicines for cardiovascular indications. In EA.hy 926 cells, a cell line derived from human umbilical vein endothelial cells (HUVEC), an aqueous extract of danshen, and also a methanol extract of the plant, increased eNOS promoter activity, eNOS mRNA and protein expression, as well as endothelial NO production. A dichloromethane extract, in contrast, did not change eNOS gene expression. Thus, the active danshen constituent(s) responsible for eNOS upregulation is (are) hydrophilic and/or alcohol-soluble. One such compound is ursolic acid that significantly increased eNOS ex…
A catalytic highly enantioselective direct synthesis of 2-bromo-2-nitroalkan-1-ols through a Henry reaction.
2008
Highly enantiomerically enriched 2-bromo-2-nitroalkan-1-ols are prepared by direct condensation of aliphatic and aromatic aldehydes with bromonitromethane in the presence of a catalytic amount of copper(II) acetate and a C1-symmetric camphorderived amino pyridine ligand.

Therapeutic effect of fractionated by ultrafiltration red beetroot (Beta vulgaris l.) juice in rats with food-induced fatty liver
2019
The prevalence of non-alcoholic fatty liver disease (NAFLD), being a component of metabolic syndrome, has increased (15-27%) in the industrialized world. The deep mechanism of this pathology is not clear, but it is multifactorial. There is a huge amount of food supplements and medicines with hepatoprotective effect on the market, but the NAFLD problem is far from being resolved. Hepatoprotective products have to provide wide spectra of biological effects, including antioxidant, hypolipidemic, anti-inflammatory action. It is peculiar to natural compounds, including red beetroot juice, which is well known to most of the population. This is important in view of the high prevalence of NAFLD. Th…
Nonalcoholic steatohepatitis: the therapeutic challenge of a global epidemic.
2011
Nonalcoholic fatty liver (NAFL) and especially its inflammatory variant nonalcoholic steatohepatitis (NASH) have become a major challenge to healthcare systems worldwide because of the increasing prevalence of its major risk factors obesity and type 2 diabetes, which are closely linked to overeating, physical inactivity, and the metabolic syndrome.Between 10 and 20% of patients with NAFL develop NASH, which can progress to cirrhosis, end-stage liver disease, and hepatocellular carcinoma. The overall mortality in these patients is significantly increased because of both cardiovascular and liver-related complications. Sustained weight loss by diet and exercise, which is the most effective the…
Need for liver evaluation in polycystic ovary syndrome
2007
Medicine is changing and requires a more in-depth knowledge also in fields that were previously considered completely different and dedicated to other specialists. A good example of this general trend is the paper by Cerda et al. [1] that shows a high prevalence of nonalcoholic fatty liver disease (NAFLD) in women with Polycystic Ovary Syndrome (PCOS). The authors studied 41 young women with PCOS and found that 17 patients (41%) had NAFLD. In addition, 7 patients with NAFLD had increased aminotransferase levels raising the possibility of a transition to nonalcoholic steatohepatitis (NASH). Other reports have shown similar data recently [2–5]. It is time therefore that doctors caring for pat…
