OBJECTIVES The purpose of this study was to investigate the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) genotype and endothelial cell dysfunction or hypercoagulable state in elderly hypertensive patients. BACKGROUND Angiotensin-converting enzyme (ACE) insertion/ deletion (I/D) polymorphism was recently reported to be associated with various cardiovascular diseases. However, t...

Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system, and there are reports in the literature describing its role in the development of cardiovascular system diseases, with I/D polymorphism of the ACE gene. We examined the relationship between a patient group with obstructive sleep apnea syndrome (OSAS) and a control group in terms of I/D polymorphis...

Genetic factors play a pivotal role in the development and pathogenesis of coronary artery disease (CAD). The angiotensin-converting enzyme (ACE) gene insertion (I)/deletion (D) polymorphism is one of the various genetic factors associated with CAD. In this study, we investigated the association between the ACE gene I/D polymorphism and CAD in the Saudi population. A total of 210 CAD patients w...

Clinical outcomes of chronic hepatitis B virus (HBV) infection vary widely. In addition to host factors, several viral factors including HBV genotype, viral load, specific viral mutations and quantitative HBsAg levels, have been associated with disease outcomes. Among viral factors, HBV genotype correlates with not only the clinical outcomes, but also with the response to interferon treatment. ...

the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

OBJECTIVES We studied the contribution of putative risk genotypes at the angiotensin I-converting enzyme inhibitor (ACE D/D) and plasminogen activator inhibitor-1 (PAI-1 4G/4G) loci to all-cause and cardiovascular mortality in a population-based cohort. BACKGROUND The ACE D/D and PAI-1 4G/4G genotypes have been consistently associated with elevated plasma activities of the gene products. Thei...

We examined the influence of the cytochrome P450 3A5 (CYP3A5) genes in both donors and recipients on the concentration-dosage ratio (C/D) of tacrolimus in Chinese liver transplant patients. Fifty-one adult liver transplant patients who received tacrolimus were included in this study. The CYP3A5 polymorphism in donors and recipients was determined at the time of transplantation, and tacrolimus-b...

conclusions in conclusion, the prevalence of hbv infection was low in the south of iran, but genotype d represented the major hbv genotype in this population. among the variables, age, duration of hd, history of blood transfusion, and using shared hd devices influenced the prevalence of hbv among hd patients. results both kinds of assay determined that nine (5.88%) patients were hbv positive (h...

The deletion (D)/insertion (I) polymorphism in intron 16 of the angiotensin-converting enzyme (ACE) gene has the greatest impact on serum ACE level in Caucasians of any factor yet discovered. The aim of the present study was to establish new ACE genotype-corrected normal ranges for serum ACE level in a population of central European origin. After a medical examination, 159 healthy Caucasians vo...

BACKGROUND Hepatitis B virus (HBV) is an etiological agent of acute and chronic liver disease existing throughout the world. The high genetic variability of HBV genome is reflected by eight genotypes (A to H), and each genotype has characteristic geographical distribution, which is important epidemiologically. Previous studies from the province of Sindh, Pakistan, have reported that genotypes A...
