The interaction of persistent antiphospholipid antibodies positivity and cigarette smoking is associated with an increased risk of cardiovascular events: Cross-sectional and longitudinal analysis.

Background: The antiphospholipid antibody (aPL)-positivity was suggested as a nontraditional risk of coronary artery disease (CAD) and it was associated with cigarette smoking. The co-occurrence of them was usually reported in individuals with cardiovascular diseases. This study was to demonstrate their interaction on the increasing risk of cardiovascular events.

Piperazine ferulate exerts antihypertensive effect and improves endothelial function in vitro and in vivo via the activation of endothelial nitric oxide synthase.

To investigate the effect of piperazine ferulate (PF) on hypertension and endothelial function, and to assess the possible underlying mechanism. Human umbilical vein endothelial cells (HUVEC), adult male Wistar Kyoto (WKY) rats aged 12 to 14 weeks, and spontaneously hypertensive (SH) and Sprague Dawley (SD) rats were used for this study. Cell viability, activities of angiotensin-converting enzyme (ACE) and heme oxygenase-1 (HO-1), in vivo NO synthesis, arterial systolic blood pressure, vascular function, expressions of endothelial NO synthase (eNOS) and phosphorylated-eNOS (p-eNOS) were determined or assessed as appropriate.

Clinical and molecular features of a Han Chinese family with maternally transmitted hypertension.

Mutations in mitochondrial DNA (mtDNA) were found to be associated with hypertension. We reported here clinical, genetic and molecular characterization of a Han Chinese family with maternally inherited hypertension. Most strikingly, this family exhibited a high penetrance of hypertension.
