Adrenomedullin 2/intermedin (AM2/IMD) is a novel vasodilator peptide with various effects on the renal function and cardiovascular system. An exonic insertion (I)/deletion (D) polymorphism (rs3840963) may influence generation of AM2/IMD-53, due to its location within the N-terminal sequence. We investigated the association of this polymorphism with blood pressure, renal function ...

Cardiovascular diseases are the leading cause of death worldwide. Essential hypertension is a major risk factor for the development of other cardiovascular diseases and is caused by a combination of environmental and genetic factors, with up to 50% of blood pressure variance currently attributed to an individual's genetic makeup. By ...

Biliverdin reductase A (BLVRA) is a powerful intracellular antioxidant enzyme and an antagonist to insulin-mediated glucose uptake by the cells. Increased oxidative stress and insulin-resistance (IR) are associated with increased risk for hypertension. Therefore, we hypothesized that BLVRA might be attributable to the variation of susceptibility to essential hypertension, and ...

BackgroundThyroid hormones (THs) exert multiple biological roles including effects on the cardiovascular system (lipid profile, blood pressure (BP) and cardiac output). The lipid-lowering actions of TH are mediated by the TH receptor-β whereas the mechanisms explaining the BP variations concomitant with the thyroid disorders are less understood. As the TH ...

BackgroundEndothelial vasodilator dysfunction contributes to the development of hypertension (blood pressure (BP) ≥140/90 mm Hg) and cardiovascular disease (CVD). Prehypertension (BP 120-139/80-89 mm Hg) has recently been identified as an independent risk factor for hypertension and CVD. It is currently unclear whether BP in the prehypertensive range is associated with endothelial vasodilator ...

Genome-wide association studies have identified several polymorphisms that appear to be on hypertension-susceptible regions. We performed the current replication study in order to evaluate the association of these loci with hypertension in healthy Japanese males and then examined the combined effect of 12 independent variants. Overall, 735 Japanese men from ...

The endogenous fibrinolytic system and the ability of the endothelium to release tissue-plasminogen activator (t-PA) play a pivotal role to protect humans from atherothrombotic events. We have recently reported that the decreased capacity for t-PA release in hypertension is restored with chronic blood pressure lowering. Thus, we explored if acute ...

Directional ClCl type I and II interactions govern the low-density aggregation of 1,1,2,2-tetrachloroethane molecules in synclinal conformation in the crystalline state at low temperature, whereas the dense molecular packing in high-pressure is achieved for the antiperiplanar conformers and electrostatically less favored ClCl contacts. The mechanism of transformation between loose and ...

Chromosome 12q24 was recently associated with hypertension. Proteasome Modulator 9 (PSMD9) lies in the 12q24 locus and is in linkage with MODY3, type 2 diabetes (T2D), microvascular and macrovascular pathology, carpal tunnel syndrome, and hypercholesterolemia in Italian families. Our goal was to determine whether PSMD9 is linked to elevated blood ...
