The genome organisation of HBV; the genes overlap. ORF S, in green, encodes HBsAg. HBsAg under a transmission electron microscope: the protein self assembles into virus-like particles. HBsAg (also known as the Australia antigen) is the surface antigen of the hepatitis B virus (HBV). Its presence in blood indicates existing hepatitis B infection.
If the host is able to clear the infection, eventually the HBsAg will become undetectable and will be followed by IgG antibodies to the hepatitis B surface antigen and core antigen (anti-HBs and anti HBc IgG). [39] The time between the removal of the HBsAg and the appearance of anti-HBs is called the window period. A person negative for HBsAg ...
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 ...
HBIG should be given within 14 days of exposure to the hepatitis B virus. [7] The half-life of HBIG is about 3 weeks. In lieu of a booster administration of HBIG, a hepatitis B vaccination is initiated at the time of the initial HBIG administration, thus providing long term protection.
Along with free software and Linux (a free operating system), copyleft licenses, the explosion of the Web and rise of P2P, the cementing of mp3 as a compression standard for recordings, and despite the efforts of the music industry, free music became largely the reality in the early 21st century.

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]
The same day, the soundtrack was released to music streaming platforms, while it was also unveiled in Telugu, Tamil, Malayalam and Kannada. [34] The songs "Arjan Vailly" and "Haiwaan", written and performed by Bhupinder Babbal and Ashim Kemson respectively, are in Punjabi and were not dubbed in the South Indian soundtracks.
Bombay is the soundtrack to the 1995 Indian film of the same name, with eight tracks composed by A. R. Rahman. [1] The film was directed by Mani Ratnam, and stars Arvind Swamy and Manisha Koirala, while the soundtrack album was released on 24 December 1994 by Pyramid. [2]
