Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OH)D concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OH)D concentrations, dietary and supplement intake of vitamin D, sun exposure mea...

The study of ACE gene I/D polymorphism has been carried out in elderly, senile and long-liver patients with coronary heart disease (CHD) taking into account their nationality, age and sex. It has been recorded that with the increase of age there is a decrease in the frequency of the genotype ACE*I/*I and a tendency of increase in the frequency of the genotype ACE*D/*D. A comparative analysis of...

The association between ACE (angiotensin-converting enzyme) gene insertion/deletion (I/D) polymorphism and mortality has been inconsistently observed in earlier studies in patients on maintenance hemodialysis. We hypothesized that the effect of ACE gene I/D polymorphism on mortality may be influenced by concurrent ACE inhibitor therapy in this population. In this prospective, multicenter cohort...

methods and materials: hepatitis b virus dna was detected by conventional pcr in some of the serum samples obtained from hbsag-positive chronic hepatitis b (chb) patients who were referred to health centers of shahrekord for routine monitoring of the disease. subsequently, using real-time pcr, the dna samples were used for genotyping and analysis of resistance to lamivudine. results: the dna wa...

The complete genomes were sequenced for ten hepatitis B virus (HBV) strains. Two of them, from Spain and Sweden, were most similar to genotype D, although encoding d specificity. Five of them were from Central America and belonged to genotype F. Two strains from Nicaragua and one from Los Angeles, USA, showed divergences of 3.1-4.1% within the small S gene from genotype F strains and were recog...

Approximately 350 million people worldwide are persistently infected with hepatitis B virus (HBV) [1], which has been classified into 8 genotypes (A–H) by means of molecular evolutionary analyses [2–4]. HBV genotypes have different geographic distributions [5]. Genotype D is ubiquitous and scattered worldwide, whereas genotype A is prevalent in sub-Saharan Africa, North America, and Eu-rope and...

AIM To confirm the presence of recombination, full-length hepatitis B virus (HBV) from chronic patients was sequenced and analyzed. METHODS Full-length HBV genomes from 12 patients were amplified and sequenced in an automated sequencer. Phylogenetic analysis was carried out on full-length, Core and preS2/Surface regions using MEGA software. SimPlot Boot Scanning and amino acid sequence analys...

Twenty-nine Danish virus isolates and 14 serum samples from patients with mumps were genotyped by nucleotide sequencing of the small hydrophobic (SH) protein gene and the deduced 57 amino acid sequences were aligned with sequences of mumps virus strains published previously. Four neurovirulent genotypes of the SH protein gene, genotypes C, D, H and a new genotype, designated J, were found. Ther...
