Phylogeography of Prunus armeniaca L. revealed by chloroplast DNA and nuclear ribosomal sequences.

To clarify the phytogeography of Prunus armeniaca L., two chloroplast DNA fragments (trnL-trnF and ycf1) and the nuclear ribosomal DNA internal transcribed spacer (ITS) were employed to assess genetic variation across 12 P. armeniaca populations.

Relative Telomere Length in Peripheral Blood Cells and Hypertension Risk among Mine Workers: A Case-Control Study in Chinese Coal Miners.

Hypertension is a common chronic disease in middle-aged and elderly people and is an important risk factor for many cardiovascular diseases. Its pathogenesis remains unclear. Epidemiological studies have found that the loss of telomere length in peripheral blood cells can increase the risk of coronary heart disease, myocardial infarction, and other diseases.

SIRT3 reduces lipid accumulation via AMPK activation in human hepatic cells.

Objective: Sirtuin 3 (SIRT3) is a nicotinamide adenine dinucleotide (NAD)(+)-dependent protein deacetylase localized on mitochondria and regulates the adaptive thermogenesis in brown adipocytes. This study aims to investigate the role of SIRT3 in hepatic lipid accumulation, and whether the activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK) is required.

Methods: A retroviral system was used for overexpressing of SIRT3 in HepG2 cells, whereas a lentivirus-mediated vector encoding SIRT3 small interfering RNA (siRNA) was used to infect these cells for knocking down endogenous SIRT3 expression.

Association between fecal bile acids and colorectal cancer: a meta-analysis of observational studies.

Purpose: To provide a systematic review with meta-analysis for addressing the relationship between fecal bile acids (FBAs) and colorectal cancer.

Materials And Methods: Electronic databases were searched for all observational studies that examined the relationship between FBAs and colorectal cancer or adenoma, and calculated weighted mean difference (WMD) and 95% confidence interval (CI). Publication bias was assessed with funnel plot.

Stimulation of Na+-Ca2+ exchange by purified antibody against alpha-2 repeat of Na+-Ca2+ exchanger in rat cardiomyocytes.

Aim: The aim of the present study was to investigate the effect of the antibody against alpha-2 repeat on Na+-Ca2+ exchanger (NCX) current (I(Na/Ca)). To evaluate the functional specificity of this antibody, its effects on L-type Ca2+ current (I(Ca,L)), voltage-gated Na+ current (I(Na)) and delayed rectifier K+ current (I(K)) were also observed.

Methods: The whole-cell patch-clamp technique was used in this study.
