Hepatitis B virus(HBV) is a DNA virus that replicates primarily in the liver.27Like HAV, it is a vaccine-preventable disease; however, unlike HAV, achronic diseasestate can occur with hepatitis B that can eventually lead to end-stage liver disease. HBV is primarily transmitted by percutaneous...
这个动画首先展示了一个健康的肝脏并解释了它的功能。然后动画继续解释甲型和乙型肝炎的原因,这些病毒如何传播,病毒对肝脏的影响以及可能的治疗方法。(来源:Youtube--Nucleus Medica Media)
hepatitis B core (HBc) antigen and the hepatitis B e (HBe) protein, a nonstructural protein that plays a role in immune tolerance to HBV replication. The P gene encodes the HBV polymerase, whose two motifs, a reverse transcriptase motif and an RNase H motif, code for two enzymes involved...
Chronic hepatitis B.This is a lifelong infection with HBV. People with chronic hepatitis B usually had an acute case that they weren't able to fight off.The younger you are when you're infected with HBV, the more likely it is that you will have a chronic infection. About 90% of infant...
Many adults who get hepatitis B have mild symptoms for a short time and then get better on their own. But some people are not able to clear the virus from the body, which causes a long-term infection. Nearly 90% of infants who get the virus will carry it for life. Over time, hepat...
Hepatitis B virus (HBV) infection is a major cause of liver diseases. However, the mechanisms underlying HBV infection and pathogenesis remain largely unknown. The sex-determining region Y box 4 (Sox4) is a transcriptional factor, which preferentially regulates the development of various organs, ti...
近年来,由于积极推行乙肝疫苗接种、制定规范的抗病毒治疗标准、我国公共卫生条件改善以及公众对于肝炎的认知程度提高等因素,我国新发病毒性肝炎显著减少,但由于慢性病毒性肝炎患者的存量较大、基数较大,我国肝炎负担仍然较重。 肝炎顾名思义就是肝脏发炎。引起...
In Japan, there is no publicly funded screening for hepatitis B virus (HBV) and hepatitis C virus (HCV) infections (using HBs antigen and HCV antibody, respectively) among workers, and workplace health programmes play a crucial role in reducing viral hep
IntroductionThe hepatitis B virus (HBV) causes up to a million deaths worldwide and 16 million health care related infections in the tropics each year(1,2), and over 350 million become chronically infected carriers who have no significant liver disease; approximately three quarters of them are ...
RCV may be detected by immunohistochemistry and serological tests like IFA and ELISA, recommended for confirmation prior to exposure. Also, RT-PCR targeted to the M gene from infected tissue or feces is used to confirm active infection (Besselsen et al., 2002;Percy and Barthold, 2008a,b)....
