Objective: Aim: To investigate allele frequencies of rs1799983 polymorphism eNOS genes and to determine association between rs1799983 polymorphism of eNOS gene and essential hypertension in Iraqi hypertensive patients.
Patients And Methods: Materials and Methods: This is an observational cross sectional descriptive single center study. ninety hypertensive patients were recruited by specialist cardiologist and conducted at AL-Diwaniyah teaching hospital and department of pharmacology and therapeutics, college of medicine, university of Al-Qadisiyah, Iraq. DNA samples were genotyped by PCR-tetra-arm method. NO level was measured by using ELISA kit.
Results: Results: Regarding rs1799983 the most frequent allele was G (73%) and the most frequent genotype was GG (55%). Our results indicate lack of substantial link between genotype frequencies of rs1799983 polymorphism and NO level (p=0.88) and thereby there is no statistically significant effect on SBP and DBP (p = 0.051).
Conclusion: Conclusions: our study demonstrated lack of significant association between this polymorphism and essential hypertension in Iraqi hypertensive patients.

Background: We performed the present study to better elucidate the correlation of nitric oxide synthase 3 (NOS3) gene polymorphism with the risk of pulmonary arterial hypertension (PAH).
Material/methods: According to the designed search strategy, a systematic literature search was performed through the PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP and Wan Fang databases to collect published case-control studies on the correlation between NOS3 gene polymorphism and PAH. The search deadline was December 26, 2023.

Objective: Aim: The main aim of the present paper is to investigate allele frequencies of rs1799983 polymorphism eNOS genes and to determine association between rs1799983 polymorphism of eNOS gene and essential hypertension in Iraqi hypertensive patients.
Patients And Methods: Materials and Methods: Data obtained at the Al-Diwaniyah teaching hospital in Iraq by researchers from the Department of Pharmacology and Therapeutics in the College of Medicine at University of Al-Qadisiyah from July 2022 to July 2023. All participants (aged 20 to 70) had been taking valsartan 160 mg once day for essential hypertension for at least two weeks before to the study.
Background: Chronic kidney disease (CKD) is defined by gradual deterioration of renal parenchyma and decline of functioning nephrons. The risk of cardiovascular events is drastically increased in patients with CKD. This complicated link of CKD and cardiovascular disease (CVD) is not well understood till date.

To investigate the association between single nucleotide polymorphism (SNP) at the rs3918188, rs1799983 and rs1007311 loci of the endothelial nitric oxide synthase (eNOS) gene and genetic susceptibility to systemic lupus erythematosus (SLE) in northeastern China. The base distribution of eNOS gene rs3918188, rs1799983 and rs1007311 in 1712 human peripheral blood samples from Northeast China was detected by SNaPshot sequencing technology. The correlation between genotype, allele and gene model of these loci of the eNOS gene and the genetic susceptibility to SLE was investigated by logistic regression analysis.
