Weekend fasting improved glucose metabolism, lowered BP, reduced LDL-C levels, BMI, and WC. These data suggest that weekend fasting may be an effective therapy for MetS by protection against coronary atherosclerosis.
Obesity-related traits have been associated with coronary artery disease (CAD) in observational studies, but these associations may be biased by confounding factors and reverse causation. In this study, we specifically conducted two-sample Mendelian randomization (MR) analyses to overcome these limitations and test the associations of obesity-related traits (other than body mass index (BMI)) (n = 322,154) with CAD (22,233 cases and 64,762 controls) by using summary-level data from previous studies. The methods utilized to estimate these associations included the inverse-variance weighted method, the weighted median method and MR-Egger regression. Our results supported causal effects of BMI, hip circumference (HC), waist circumference (WC), and waist-hip ratio (WHR) on CAD. The associations of BMI-adjusted HC and WC with CAD were reversed, unlike that of WHR. In MR analyses excluding overlapping single nucleotide polymorphisms (SNPs) from obesity-related traits, the associations of these traits with CAD were preserved. The associations of BMI-adjusted HC and WC with CAD require further investigation, as collider stratification may be occurring. Additionally, central adiposity (measured by WHR) separated from general adiposity (measured by BMI) and general adiposity might pose similar risks for CAD. In clinical practice, physicians should pay attention to the potential effects of different obesity-related traits on CAD.
Background: Autism, a heterogeneous disease, is described as a genetic psychiatry disorder. Recently, abnormalities at the synapse are supposed to be important for the etiology of autism.SHANK3 (SH3 and multiple ankyrin repeat domains protein) gene encodes a master synaptic scaffolding protein at postsynaptic density (PSD) of excitatory synapse. Rare mutations and copy number variation (CNV) evidence suggested SHANK3 as a strong candidate gene for the pathogenesis of autism.
The purpose of this study was to demonstrate the aberrant metabolism of bile acids in patients with cholesterol gallstone and explore for its underlying mechanisms.The composition of bile acids collected from the patients with cholelithiasis and the control individuals was analyzed by LC-MS. The expression of genes regulating the metabolism of bile acids were quantitatively determined by real-time PCR or Western blotting. Cholesterol saturation index of patients with gallstone was significantly higher than that of the controls. The concentrations of taurodeoxycholic acid and taurolithocholic acid in the bile of patients were significantly higher than that of the controls. When compared to the controls, it was remarkable in the patients that the mRNA expression of FXR was lower whereas that of OATP1A2 was higher. However, the expressions of both mRNA and protein of CYP8B1 did not differ between the patients and the controls. Although the protein level of CYP8B1 was significantly lower in the subjects with SNP rs3732860(G), the composition of bile acids and the ratio of CA to CDCA remained unaltered in the patients with different SNP genotype of CYP8B1. In conclusion, the axis of FXR-OATP1A2 that physiologically regulated the reabsorption of bile acids might play an important role in the composition of bile acids and the development of gallstone. CYP8B1 gene was irrelevant to the altered composition of bile acids in patients with gallstone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
