(Phys.org)—Depending on the strain, or genotype, of the human papillomavirus (HPV) (see image), the lesions it causes can range from relatively benign to cancer-causing. Differentiating between lesions caused by low-risk and high-risk viral genotypes, however, is difficult. Françoise Thierry at the A*STAR Institute of Medical Biology in Singapore and co-workers have now identified proteins that could be used as reliable, sensitive markers to diagnose infections with high-risk types of HPV. http://phys.org/news279965874.html Biology Wed, 13 Feb 2013 08:18:09 EST news279965874 An inexpensive new test for the detection of Hepatitis B virus has been given regulatory approval for use in the European Union. The test, developed with support from the Wellcome Trust, delivers accurate results while-you-wait, enabling doctors to take immediate action on health decisions. http://phys.org/news193408643.html Medicine & Health Tue, 18 May 2010 14:00:01 EST news193408643 Scientists in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women. Their study has been published online in ACS' Journal of Proteome Research. http://phys.org/news177772349.html Chemistry Wed, 18 Nov 2009 15:20:01 EST news177772349 Researchers at The University of Texas School of Public Health have developed a game for HIV-positive youth, +CLICK, designed to reduce secondary transmission of the virus. http://phys.org/news164980227.html Medicine & Health Tue, 23 Jun 2009 12:51:09 EST news164980227
