Abstract Background and Objectives Hepatitis B virus (HBV) infection remains a serious global health challenge. Hepatitis B infection is one of the major diseases transmitted by blood transfusion. Infection with the virus can cause extensive liver damage. So far, 10 genotypes have been identified for hepatitis B. The aim of this study was to do Hepatitis B virus genotyping in asymptomatic HBV...
BACKGROUND Hepatitis B virus (HBV) genotype and its role in disease progression and patients' response to antiviral treatment, is not well studied in Pakistan. This comprehensive study was aimed to determine the distribution of HBV genotypes in Pakistan and their possible association with phases of HBV infection. METHODS A total of 840 HBsAg positive samples was collected and tested for HBV D...
The prevalence of hepatitis B virus (HBV) markers was investigated in 563 inhabitants aged 15-55 years from a sugar cane region, Sirama, and from a village, Mataipako, in Northern Madagascar. Serological markers of past or present infection were significantly higher in Sirama, 74% versus 45%. There was no difference in the prevalence of chronic HBsAg carriers, 8.7% versus 8.5% between the two r...
BACKGROUND & OBJECTIVES Non-detection of hepatitis B virus (HBV) envelope protein (hepatitis B surface antigen, HBsAg) in a chronically HBV infected individual has been described as occult infection. One possible reason for this phenotype is alteration in large (L-HBsAg) to small (S-HBsAg) envelope protein ratio associated with reduced or non secretion of HBsAg. This results in quantitative lev...
Introduction: The identification of the factors affecting the physical performance and development of childrenchr('39')s motor skills can be of great importance in participating in physical activities, preventing overweight and obesity, as well as identifying and guiding the top talented children in sport. Therefore, this study aimed to investigate the effect of different ACE (I/D) and ACTN-3 (...
Two hepatitis B virus (HBV) C/D recombinants were isolated from western China. No direct evidence indicates that these new viruses arose as a result of recombination between genotype C and D or a result of convergence. In this study, we search for evidence of intra-individual recombination in the family cluster cases with co-circulation of genotype C, D and C/D recombinants. We studied 68 indiv...
breast cancer (bc) is considered as one of the most important causes of death worldwide. previous studies showed that apolipoprotein b mrna- editing catalytic polypeptide-like 3 (apobec3) gene deletion significantly increased the risk of bc risk in chinese and european women. the present study aimed to assess the possible impact of apobec3 deletion and the risk of bc in a sample of iranian popu...
This study aimed to estimate the distribution of hepatitis B virus (HBV) C/D recombinant in Han and Tibet patients with chronic hepatitis B (CHB) and then learn such strain's replication capacity in vivo. A total of 331 serum samples were collected from Han outpatients from Sichuan Province and Tibetan outpatients from Tibet. Viral genotypes in these samples were identified. An HBV replicative ...
