It was known that the RNA genome is wrapped in a helical structure by the viral nucleocapsid (N) protein, but how this structure was encased by the viral matrix (M) protein and the envelope was not clear. These questions have been elegantly answered by a new model of the VSV virion determined by cryo-electron microscopy. The RNA genome of VSV is coated with many copies of the N protein to form a nucleocapsid with helical symmetry. The nucleocapsid is in turn surrounded by the M protein and then the viral membrane. The reconstructed image (right) not only shows the helical nature of the N protein – RNA... virology blog blogs http://www.medworm.com/rss/comments.php?id=3298010 Tue, 23 Feb 2010 04:00:43 +0100 3298010 http://www.medworm.com/index.php?rid=2820455&cid=t_230616_125_f&fid=34820&url=http%3A%2F%2Fwww.dentalblogs.com%2Farchives%2Fadministrator%2Fcutting-edge-dentistry-and-stem-cells%2F In light of the 2009 World Stem Cell Summit in Baltimore this week, DentalBlogs brings you the news on stem cell research and procedures in dentistry. Dental Pulp Stem Cells (DPSC) can differentiate into various types of cells, then multiply to rebuild tissue. Embryonic cord stem cells have been used to regenerate blood cells, but dental stem cells can create many other types of tissues, such as connective, muscular, bone, dental, and even neuronal. Recently, DentalBlogs posted an article regarding the successful implantation of stem cells that resulted in a mouse growing a new tooth. According to a Nova Southeastern University survey, 96% of dentists predict that stem cell regeneration will “dominate the future of dentistry.” More than half of surveyed dentists believe that they will ... dental blog for dentists about dentistry blogs http://www.medworm.com/rss/comments.php?id=2820455 Tue, 22 Sep 2009 15:24:22 +0100 2820455 http://www.medworm.com/index.php?rid=2261882&cid=t_230616_160_f&fid=38218&url=http%3A%2F%2Fwaronwarts.com%2F2009%2F03%2Fusing-liquid-nitrogen-to-treat-hpv%2F by: Michelle Lipke Liquid nitrogen is a popular destructive treatment for warts.  It is readily available in both dermatology and primary care offices.   Verucca-Freeze and many similar brands available over the counter are a liquid applied from a spray can, but only freeze to -70C.  Warts may not resolve with the over the counter freezing due to the fact that they do not freeze as fast as the liquid nitrogen available in the clinic setting; as well as the proper application technique may not always be used. The wart virus, known as human papilloma virus (HPV), is not destroyed by the freezing procedure.   Liquid nitrogen freezes at -196C and works by destroying the skin cells which in turn release the wart virus.  They body responds to this process by causing an immune response to ...
