Discovery of epigenetic modifications associated with feed efficiency or other economically important traits would increase our understanding of the molecular mechanisms underlying these traits. In combination with known genetic markers, this would provide opportunity to improve genomic selection accuracy in cattle breeding programs. It would also allow cattle to be managed to improve favorable gene expression. The objective of this study was to identify variation in DNA methylation between beef cattle of differential pre-natal nutrition and divergent genetic potential for residual feed intake (RFI). Purebred Angus offspring with the genetic potential for either high (HRFI) or low (LRFI) RFI were prenatally exposed to either a restricted maternal diet of 0.5 kg/d average daily gain (ADG) or a moderate maternal diet of 0.7 kg/d ADG from 30 to 150 d of gestation. We performed DNA methylation analysis of differentially methylated regions (DMR) of imprinted genes (Insulin-like growth factor 2 (IGF2) DMR2, IGF2/H1diet steers compared with moderate diet steers at weaning and/or slaughter. Our results suggest that differential pre-natal nutrition, and divergent genetic potential for RFI, induces tissue- and sex-specific alterations in post-natal IGF2 and IGF2R methylation patterns and that these patterns can vary with age in Angus beef cattle.
The purpose of this study is to examine the predictive utility of polygenic risk scores (PRSs) for smoking behaviors.

Using summary statistics from the GWAS and Sequencing Consortium of Alcohol and Nicotine use consortium, we generated PRSs of ever smoking, age of smoking initiation, cigarettes smoked per day, and smoking cessation for participants in the population-based Atherosclerosis Risk in Communities (ARIC) study (N=8,638), and the Collaborative Genetic Study of Nicotine Dependence (COGEND) (N=1,935). The outcomes were ever smoking, age of smoking initiation, heaviness of smoking, and smoking cessation.

In the European ancestry cohorts, each PRS was significantly associated with the corresponding smoking behavior outcome. In the ARIC cohort, the z-score ever smoking PRS predicted ever smoking (odds ratio [OR] 1.37; 95% confidence interval [CI] 1.31, 1.43); the z-score age of smoking initiation PRS was associated with earlier age of smoking initiation (OR0.87 95% CI 0.82, 0.92); the z-score cigarer substantial and meaningful predictive power. However, with increasing work in polygenic risk scores, the predictive ability will continue to improve.
This study shows that including both genetic ancestry and polygenic risk scores in a single model increases the ability to predict smoking behaviors compared to the model including only demographic characteristics. This finding is observed for every smoking-related outcome. Even though adding genetics is more predictive, the demographics alone confer substantial and meaningful predictive power. However, with increasing work in polygenic risk scores, the predictive ability will continue to improve.A 59-year old male was found dead at home, with 2 empty vials of an oily preparation attributed to a manufacturer from East Europe. There was no label on the vial. The subject was a former weightlifter, also known as an anabolic steroids abuser. The local prosecutor ordered a body examination, which was unremarkable and allowed collecting femoral blood, urine and scalp hair (6 cm, brown). He was treated for cardiac insufficiency with quinidine. Biological specimens were submitted to standard toxicological analyses including a screening with LC-QToF, but also to a specific LC-MS/MS method for anabolic steroids testing. Ethanol was not found in both blood and urine. Quinidine blood concentration (791 ng/mL) was therapeutic. No drug of abuse was identified. In blood, testosterone was less that 1 ng/mL and no other steroid was identified. In urine, T/E was 1.56 and boldenone showed up at 9 ng/mL. The hair test results, performed on the whole length, demonstrated repetitive steroids abuse, including testosterone (140 pg/mg), testosterone propionate (605 pg/mg) and testosterone decanoate (249 pg/mg), but also boldenone (160 pg/mg), trenbolone (143 pg/mg) and metandienone (60 pg/mg). Given forensic laboratories have limited access to steroid urinary metabolites reference material due to specific regulations (to avoid testing athletes before anti-doping verifications), hair analyses seem to be the best approach to document anabolic agents abuse. Indeed, in hair, the target drug is the parent compound and, in addition, when compared to blood or urine, this matrix has a much larger window of detection. The pathologist concluded to cardiac insufficiency in a context involving repetitive abuse of anabolic drugs. This case indicates that more attention should be paid to anabolic steroids, in a context of sudden cardiac death.
Obesity management prior to infertility treatment remains a challenge. To date, results from randomized clinical trials involving weight loss by lifestyle interventions have shown no evidence of improved live birth rate.

To determine whether pharmacologic weight-loss intervention before in vitro fertilization and embryo transfer (IVF-ET) can improve live birth rate among overweight or obese women.

We conducted a randomized, double-blinded, placebo-controlled trial across 19 reproductive medical centers in China, from July 2017 to January 2019. selleck inhibitor A total of 877 infertile women scheduled for IVF who had a body mass index of 25kg/m 2 or greater were randomly assigned.

The participants were randomized to receive orlistat (n=439) or placebo (n=438) treatment for 4-12 weeks.

Live birth rate after fresh embryo transfer.

The live birth rate was not significantly different between the two groups (112 of 439 [25.5%] with orlistat and 112 of 438 [25.6%] with placebo; P=.984). No significant differences existed between the groups as to the rates of conception, clinical pregnancy, and pregnancy loss. A statistically significant increase in singleton birthweight was observed after orlistat treatment (3487.50g versus 3285.17g in the placebo group; P=.039). The mean change in body weight during the intervention was -2.49kg in the orlistat group, as compared to -1.22kg in the placebo group, with a significant difference (P=.005).

Orlistat treatment, prior to IVF-ET, did not improve live birth rate among overweight or obese women, although it was beneficial for weight reduction.
