OBJECTIVE To evaluate whether an association between risk of any of the factors of hypertension, alcohol intake, and cigarette smoking and the risk of primary open-angle glaucoma (POAG) depended on nitric oxide synthase 3 (NOS3) gene variants. METHODS Two functional single-nucleotide polymorphisms (SNPs) (T-786C [rs2070744] and Glu298Asp [rs1799983]) and 2 tagging SNPs (rs7830 and rs3918188) ...

Impaired endothelial function caused by decreased NO production plays a pathophysiologic role in essential hypertension. Although cross-sectional data are available on the association between endothelial NO synthase gene polymorphisms and hypertension, whether the gene variants and their haplotypes affect the long-term cumulative burden and trend of blood pressure since childhood is not known. ...

BACKGROUND Nitric oxide plays an important role in the regulation of basal vascular tone and cardiac myocyte function. We investigated the NOS3-786T>C polymorphism in chronic heart failure (CHF) and its effects on long-term mortality. METHODS Ninety-one patients with CHF who were referred to the Department of Cardiology of Siyami Ersek Cardiovascular and Thoracic Surgery Center for cardiopulm...
