The aim of the study was to examine the influence of riboflavin photochemical method on the inactivation of hepatitis B virus (HBV) and the functions of red blood cells. Twenty patients suffering viral hepatitis B were selected in this study, and venous blood was collected and final concentration of 1,500 µmol/l riboflavin were added, to accept the λ=400-500 nm. The light intensity of 40,000 lu...

The hepatitis delta virus (HDV) is a rarest form of viral hepatitis, but has the worst outcomes for patients.It is a subviral satellite dependent on coinfection with hepatitis B (HBV) to replicate within the host liver.To date, there has been little to no modeling effort for HDV. Deriving and analyzing such a mathematical model poses difficulty as it requires the inclusion of (HBV). Here we beg...

OBJECTIVE To determine the responsibility of hepatitis B virus (HBV) and hepatitis C virus (HCV) and therapeutic implications in a patient who developed systemic vasculitis. CASE REPORT The case of a 38 year old woman who had a past history of addiction to intravenous drugs and developed systemic vasculitis after infection by HBV and HCV is described. The clinical and laboratory findings subs...

Background. Chronic hepatitis B (CHB) remains a severe global public health concern. Hepatitis B virus (HBV) can be divided into 8 genotypes with different geographical distribution and virological features. We demonstrated genotypes B and C prevalent in southern and northern China, respectively, had divergent genotype-dependent amino acid polymorphisms and variations in reverse transcriptase (...

Introduction: Occurrence of detectable amounts of viral antigen or viral particles in the blood of infected patients with Hepatitis B virus (HBV) is a significant characteristic of HBV infection. Detection of HBV antigen or its DNA among individuals of a community is a crucial factor to know the burden of HBV infection. Hepatitis B surface antigen (HBsAg) is a suitable marker of HBV infection b...

background and aims: the aim of this study was to determine the correlation between the hepatitis b virus surface ag (hbsag) genotypes and variations in the clinical/serological pictures among hbsag positive chronic patients from south khorasan province of iran. methods: twenty-five patients were enrolled in this study. the hbs ag gene was amplified and was directly sequenced. genotypes and nuc...
