Background: Hepatitis viruses are non-cytopathic viruses that lead to the infection and pathogenesis of liver diseases as a result of immunologically mediated event. Objective: To investigate the expression of human inflammatory cytokines in chronic hepatitis B patients according to the severity of the infection.

Background and Objectives: Immune deficiency syndrome is an epidemic disease. During immunodeficiency caused by HIV, infections such as tuberculosis, hepatitis B and hepatitis C may occur. Given that the transmission of these infections is similar to that of HIV, the risk of HIV infection with these infections is high. The purpose of this study was to determine the prevalence of common HIV infe...
In this study, we propose new illustrative and effective modeling to point out the behaviors of Hepatitis-B virus (Hepatitis-B). Not only do consider mathematical modeling, equilibria, stabilities, existence–uniqueness analysis model, but also, make numerical simulations by using Adams–Bashforth scheme. However, apply parameter estimation method determine our model parameters find curve that be...

Abstract Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal co...
