Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...

conclusions these findings indicate relatively high prevalence rate of ha infection among nurses and paramedical personnel at this hospital. nevertheless, 30% of the health workers have been seronegative and are still at risk of ha infection development. considering that the disease has more severe course as age increases, improvement of standard hygiene and prevention strategies are recommende...

conclusions as it was previously reported by the world health organization (who) on hav infection in the country, this study revealed a high prevalence of hav infection in mashhad. background hepatitis a virus (hav) is the most common cause of acute viral hepatitis worldwide, mostly in developing countries. objectives this population-based survey was performed to investigate hav seroprevalence ...

Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...

    Abstract   Background: Hepatitis B virus infection is an important cause of liver morbidity and   mortality worldwide. HDV changes the natural course of HBV. The prevalence of HDV infection wasn’t determined in the various groups of HBV infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and HCC) in Iran. We aimed to research the prevalence of hepatitis D virus infection in v...

Background and Aims: Iron oxide nanoparticles are among the most effective tools which can replace current medical techniques for diagnosis and treatment of various diseases. Hepatitis C infection is one of the main health problems in the world, affecting around 3% of the world's population. This infection can develop into liver cirrhosis and liver cancer over the time in 80% of patients. In t...

the burden of exposure to blood-borne pathogens (such as hepatitis b and c viruses) is considerable for health care workers. hepatitis virus transmission requires a non-immune host, an infectious source, and skin or mucous membrane injury. these three aspects are the main fields for preventional interventions. we reviewed major recent studies on this topic to identify precautions health care wo...

conclusions cd5l might be a useful biomarker for early diagnosis of hcc in hcv cirrhotic patients. lrg and hp α2 isoforms could be potential markers for distinguishing viral hcc. our results also further support the presence of varying molecules involved in hepatocarcinogenesis in hbv when compared with hcv infection. patients and methods two-dimensional polyacrylamide gel electrophoresis combi...

conclusions hbv and hcv are important culprits of hcc in emro countries and the middle east and different nations need different strategies to tackle them accordingly. countries with high rates of hbv such as turkey should continue their hbv vaccination and also increase sanitation. nations with high hcv rates such as egypt should maintain their blood product monitoring in addition to increased...

DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
