Background Varicocele is an abnormal dilation and tortuosity of veins of pampiniform plexus that drains the testis and causes an important change in semen.This abnormality is often one of the most common risk factors for male infertility. The aim of this study was to investigate the relationship between nitric oxide synthase 3 (NOS3) 4a4b (rs61722009) gene polymorphism, as a common genetic fact...

BACKGROUND Previous studies inferring that the NOS3 gene was associated with the pathogenesis of metabolic syndrome (MetS) had inconsistent findings. We investigated the role of three NOS3 polymorphisms (T-786C, intron 4b/a, and G894T) in the risk of MetS using a hospital-based case-control study. METHODS We recruited 339 MetS cases and 783 non-MetS controls at a central Taiwanese hospital. I...

AIM Sexual dysfunction induced by antipsychotic drug treatment is under investigated and under reported. This study aimed to determine the influence of genetic polymorphisms in the D2 dopamine receptor (DRD2) and endothelial nitric oxide synthase (eNOS) genes, and the possible role of blood prolactin concentrations on sexual function in schizophrenic patients. MATERIALS & METHODS Male remitte...

Coronary heart disease (CHD) is based on the development of atherosclerosis in coronary arteries. Shear stress-induced endothelial nitric oxide (NO) release not only contributes to local blood pressure control but also effectively helps to retard atherosclerosis. Therefore, functionally relevant polymorphisms in the endothelial NO synthase (NOS-3) gene may contribute to the development of CHD. ...

The purpose of our meta-analysis is to examine the associations between three single nucleotide polymorphisms of endothelial nitric oxide synthase (eNOS) gene, G894T, intron 4 and T-786C, and the risk of erectile dysfunction. An electronic database search was performed to identify case-control studies reporting the association between single nucleotide polymorphisms of eNOS gene and erectile dy...

The aim of this study was to evaluate the association of single nucleotide polymorphisms (SNPs) T-786C and G894T in the gene encoding eNOS with blood pressure variability (BPV) in man. Blood pressure was recorded beat-to-beat at rest three times in periods of one week (5 min, Finapres, breathing at 0.33 Hz) in 152 subjects (19-24 years). Systolic (SBPV(0.1r)/SBPV(0.1a)) and diastolic (DBPV(0.1r...

Abstract The problem of cardiovascular comorbidity becomes particularly relevant in the context a pandemic, since it is known that diseases (especially arterial hypertension – AH and coronary heart disease CHD) significantly increase frequency hospitalizations fatal outcomes patients with COVID-19. From these positions, fundamentally important to identify group individuals high prognostic proba...

Background. Hyperhomocysteinemia has been suggested to play a role in the NonValvular Atrial Fibrillation (NVAF) pathogenesis. Polymorphisms in genes coding for homocysteine (Hcy) metabolism enzymes may be associated with hyperhomocysteinemia and NVAF. Methodologies. 456 NVAF patients and 912 matched controls were genotyped by an electronic microchip technology for C677T and A1298C MTHFR, A2756...
