RESULTS:Of the 1018 individuals,5.5%tested positive for *** were tested positive for *** the HBsAg-positive population,58.93%were HBeAg- positive and the rest 41.07%*** was a male predominance and those who were tested positive were mostly between 16 and 50 years of *** risk factors for exposure to HBV appeared to be injudicious use of injectable medications,treatment by unqualified, traditional practitioners,mass-vaccination against cholera and smallpox,barbers and body piercing. CONCLUSION:HBV remains a major cause of morbidity and mortality in Bangladesh and we have a long way to go before we may bid farewell to this deadly menace.

A study has been arranged to investigate the flow of non-Newtonian fluid in a vertical asymmetrical channel using peristalsis. The porous medium allows the electrically conductive fluid to flow in the channel, while a uniform magnetic field is applied perpendicular to the flow direction. The analysis takes into account the combined influence of heat and mass transfer, including the effects of Soret and Dufour. The flow’s non-Newtonian behavior is characterized using a Casson rheological model. The fluid flow equations are examined within a wave frame of reference that has a wave velocity. The analytic solution is examined using long wavelengths and a small Reynolds number assumption. The stream function, temperature, concentration and heat transfer coefficient expressions are derived. The bvp4c function from MATLAB has been used to numerically solve the transformed equations. The flow characteristics have been analyzed using graphs to demonstrate the impacts of different parameters.

BACKGROUND:Bangladesh is situated in the intermediate prevalence region of hepatitis B virus (HBV).The lifetime risk of acquiring HBV infection in Bangladesh is greater than 40%.It has been estimated that this virus is responsible for 10%-35%cases of acute viral hepatitis,35.7%cases of fulminant hepatic failure, 33.3%-40.5%cases of chronic hepatitis and 46.8%cases of hepatocellular carcinoma in *** aim of this study is to compare the correlation between HBV DNA load and grade and stage of liver disease in patients with chronic hepatitis B(CHB).

BACKGROUND:Hepatitis B virus(HBV)infection is a major cause of mortality and morbidity *** quest continues to identify viral factors that influence disease progression and severity as well as responses to treatment of HBV *** on variations in HBV,the virus has been divided into a number of genotypes. DATA SOURCES:Review of published literature on HBV genotypes. RESULTS:HBV genotypes are likely to be important in determining the severity and progression of HBV-induced liver disease as well as responses to different anti-viral agents. CONCLUSION:Although HBV genotyping is not yet recommended for routine use in treating HBV infection, available data suggest that,as in hepatitis C virus infection, HBV genotyping is also likely to become a routine investigation for HBV treatment,perhaps in the not too distant future.
