we created a simple cellular automata (ca) model for hepatitis b infection dynamics associated with spatial structure performed under various ages of liver tissue correspond to different immune responses in order to study the effect of spatial heterogeneities on the dynamical evolution of a viral infection. the results of the simulations show biphasic nature of viral load decreases, as observed...

conclusions our investigation illustrated that the prevalence of hepatitis c was higher among olp patients compared to the control group. these findings are in line with previous results that reported a hepatitis c prevalence of 0.19% among the general population of mashhad. results of the 134 olp patients only three (2.23 %) had hcv infection where both anti-hcv and hcv-rna were positive. all ...

amyotrophic lateral sclerosis is a progressive neurodegenerative disease with uncertain etiology. for many years, viruses have been suspected as causative agents. there are conflicting reports about the possible role of viruses such as human herpes virus 8 (hhv8) and retroviruses in the pathogenesis of the sporadic amyotrophic lateral sclerosis. we conducted a prospective case-control study to ...
