These results, which have been published in the latest edition of PNAS, could be crucial to the design of future antiretrovirals. http://medicalxpress.com/news/2012-12-crucial-aids-virus-maturation-simulated.html HIV & AIDS Tue, 04 Dec 2012 04:16:46 EST news273816986 To date, 10 people have fallen ill - and three have died - in the hantavirus outbreak at Yosemite National Park's "signature" cabins in Curry Village, according to the U.S. Centers for Disease Control and Prevention. http://medicalxpress.com/news/2012-11-cdc-yosemite-hantavirus-outbreak-sickened.html Diseases, Conditions, Syndromes Thu, 22 Nov 2012 11:40:01 EST news272803524 New research suggests that just one or two individual herpes virus particles attack a skin cell in the first stage of an outbreak, resulting in a bottleneck in which the infection may be vulnerable to medical treatment. http://medicalxpress.com/news/2012-11-unexpected-bottleneck-herpes-simplex-virus.html Medical research Mon, 05 Nov 2012 13:12:26 EST news271343524 Scientists from the University of Utah School of Medicine have discovered that a mouse protein called IFITM3 contributes to the body's defense against some types of viral infections by binding to an enzyme responsible for regulating the pH of a cell's waste disposal system. This finding, published in the March 30, 2012, issue of Innate Immunity, sheds light on the cellular mechanisms involved in flu resistance and opens up potential new avenues of research for anti-viral medications. http://medicalxpress.com/news/2012-04-reveals-insight-key-protein-viral.html Immunology Mon, 02 Apr 2012 09:16:56 EST news252576998 Researchers at the University of British Columbia have found a new way to block infection from the hepatitis C virus (HCV) in the liver that could lead to new therapies for those affected by this and other infectious diseases. http://medicalxpress.com/news/2012-01-potential-therapy-approach-hepatitis.html Diseases, Conditions, Syndromes Mon, 16 Jan 2012 03:20:01 EST news245904303 (Medical Xpress) -- Researchers from the University of Reading have developed a new drug which could reduce the spread of deadly diseases such as Lassa Fever and Aseptic Meningitis. http://medicalxpress.com/news/2011-09-drug-combat-killer-diseases.html Medical research Fri, 30 Sep 2011 07:18:56 EST news236585879 University of Queensland researchers have produced batches of a monoclonal antibody, which may offer hope as a potential therapeutic for Hendra virus infection in humans. http://medicalxpress.com/news/2011-07-hendra-virus-facts.html Diseases, Conditions, Syndromes Tue, 12 Jul 2011 10:58:43 EST news229687106
