HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]
Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV) that affects the liver; [1] [6] it is a type of viral hepatitis. [7] It can cause both acute and chronic infection. [1] Many people have no symptoms during an initial infection.
The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest.
The recombinant vaccine is based on a Hepatitis B surface antigen gene inserted into yeast (Saccharomyces cerevisiae) cells which are free of any concerns associated with human blood products. [ 17 ] [ 65 ] This allows the yeast to produce only the noninfectious surface protein, without any danger of introducing actual viral DNA into the final ...
Acute Hepatitis B is a short-term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older.
For the medical community, the Hepatitis B Foundation organizes the International HBV Scientific Meeting annually for scientists discuss to new discoveries in hepatitis B research. [12] The organization is also actively involved in policy-making, helping ensure hepatitis B is a health priority at the local and federal level. [13] [14] [15]
San Francisco Hep B Free is a citywide campaign to turn San Francisco into the first hepatitis B free city in the United States.This unprecedented campaign began in 2007, with the objective to screen, vaccinate, and treat all San Francisco Asian and Pacific Islander (API) residents for hepatitis B by providing convenient, free or low-cost testing opportunities at partnering health facilities ...
