Thirty years after the AIDS epidemic first surfaced, more people than ever before in the United States -- more than 1.1 million -- are living with HIV, the Centers for Disease Control said Thursday. http://phys.org/news226256138.html Medicine & Health Thu, 02 Jun 2011 18:40:01 EST news226256138 A certain gene in some monkeys can help boost vaccine protection against simian immunodeficiency virus (SIV), a trait that could help researchers develop better AIDS vaccines for humans, suggested a study out Wednesday. http://phys.org/news223738128.html Medicine & Health Wed, 04 May 2011 14:29:17 EST news223738128 (PhysOrg.com) -- By striving for control and perfection in everything from computer chips to commercial jets, scientists and engineers actually exclude a fundamental force that allows nature to outperform even their best efforts. http://phys.org/news222452399.html Nanotechnology Tue, 19 Apr 2011 17:20:23 EST news222452399 An analysis of data from 10 studies indicates that the presence of low frequency (also called "minority") human immunodeficiency virus type 1 (HIV-1) drug resistance mutations, particularly those involving nonnucleoside reverse transcriptase inhibitor (NNRTI) resistance, are significantly associated with an increased risk of first-line antiretroviral treatment failure, according to an article in the April 6 issue of JAMA. http://phys.org/news221239527.html Medicine & Health Tue, 05 Apr 2011 16:25:46 EST news221239527 With the war on AIDS nearing its 30th anniversary, the UN on Thursday declared "a moment of truth" had come for new strategies to address the campaign's failures and brake costs that were now unsustainable. http://phys.org/news220778085.html Medicine & Health Thu, 31 Mar 2011 08:15:06 EST news220778085 The human immunodeficiency virus (HIV), the cause of AIDS, makes use of the base excision repair pathway when inserting its DNA into the host-cell genome, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. Crippling the repair pathway prevents the virus from completing this critical step in the retrovirus's life cycle. http://phys.org/news220263624.html Medicine & Health Fri, 25 Mar 2011 09:40:03 EST news220263624 Human Immunodeficiency Virus (HIV) – which causes AIDS – invades human immune cells and causes them to produce new copies of the virus, which can then infect new cells. A research team led by Professor Don C. Lamb (Ludwig-Maximilians-Universität in Munich) and Priv.-Doz. Dr. Barbara Müller of Heidelberg University Hospital have now analyzed the involvement of particular components of the infected cell in virion release, and discovered that the enzyme VPS4A plays a more active role in the process than was previously thought. VPS4A was already known to act after virus budding was complete. Using an advanced microscopy technique, the group was able to show that complexes containing about a dozen VPS4A molecules form at points in the membrane at which newly assembled virions later emerge. http://phys.org/news219058742.html Biology Fri, 11 Mar 2011 09:39:26 EST news219058742 The American Thoracic Society has released a new report detailing recent global changes in the management of human immunodeficiency virus (HIV)-associated pulmonary disease. The report examines the evolving landscape of HIV and its associated diseases in areas where combination antiretroviral therapies (ART) are available, as well as offering insight into the trends occurring in areas of the world where ART use is limited. http://phys.org/news218385621.html Medicine & Health Thu, 03 Mar 2011 14:50:01 EST news218385621 New research enhances the current knowledge of how human immunodeficiency virus type-1 (HIV-1), which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dormant state, called latency. http://phys.org/news217854064.html Medicine & Health Fri, 25 Feb 2011 11:01:39 EST news217854064 French researchers determined that infection with human immunodeficiency virus (HIV) impaired results of transplant surgery for liver cancer, with more HIV infected patients dropping off the transplantation wait list. The team found that overall survival and recurrence-free survival was not impacted following liver transplantation in patients with controlled HIV disease. Details of this single center study—the largest to date—are published in the February issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD). http://phys.org/news215175928.html Medicine & Health Tue, 25 Jan 2011 11:20:01 EST news215175928 While the overall hospitalization rate for stroke has declined in recent years, the numbers have jumped dramatically for patients infected with human immunodeficiency virus (HIV), suggesting they may be up to three times more likely to suffer a stroke than people uninfected by the virus that causes AIDS. http://phys.org/news214682789.html Medicine & Health Wed, 19 Jan 2011 18:06:53 EST news214682789 A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus (HIV) to human cells. http://phys.org/news214665704.html Medicine & Health Wed, 19 Jan 2011 13:22:13 EST news214665704 New insights into the human immunodeficiency virus (HIV) infection process, which leads to acquired immunodeficiency syndrome (AIDS), may now be possible through a research method recently developed in part at the National Institute of Standards and Technology, where scientists have glimpsed an important protein molecule's behavior with unprecedented clarity. http://phys.org/news206279398.html Chemistry Thu, 14 Oct 2010 13:00:01 EST news206279398 Researchers have determined the structure of a protein that helps guide blood-forming stem cells, or hematopoetic stem cells. The protein is also one of the main receptors used by the human immunodeficiency virus (HIV) to get inside blood cells. http://phys.org/news205679979.html Medicine & Health Thu, 07 Oct 2010 14:19:58 EST news205679979 In recent human trials for a promising new class of drug designed to target the hepatitis C virus (HCV) without shutting down the immune system, some of the HCV strains being treated exhibited signs of drug resistance. http://phys.org/news204982969.html Chemistry Wed, 29 Sep 2010 12:43:02 EST news204982969 A vaginal gel failed to protect women against the AIDS virus, doctors said on Monday, reporting on a major clinical trial that enrolled more than 9,000 women. http://phys.org/news204178749.html Medicine & Health Mon, 20 Sep 2010 05:19:28 EST news204178749 Israeli researchers have developed a new treatment for HIV that kills human cells infected with the virus and could lead to a breakthrough in treating AIDS, the Haaretz newspaper said on Friday. http://phys.org/news202722295.html Medicine & Health Fri, 03 Sep 2010 08:45:23 EST news202722295 Dr. Eric A. Cohen, Director of the Human Retrovirology research unit at the Institut de recherches cliniques de Montreal (IRCM), and his team published yesterday, in the online open-access journal PLos Pathogens, the results of their most recent research on the role of the Vpr protein in HIV (human immunodeficiency virus) infection and AIDS (acquired immune deficiency syndrome). http://phys.org/news202667118.html Medicine & Health Thu, 02 Sep 2010 17:26:55 EST news202667118 Studies of the spinal fluid of patients given anti-HIV drugs have resulted in new findings suggesting that the brain can act as a hiding place for the HIV virus. Around 10% of patients showed traces of the virus in their spinal fluid but not in their blood -- a larger proportion than previously realised, reveals a thesis from the University of Gothenburg, Sweden. http://phys.org/news201776810.html Medicine & Health Mon, 23 Aug 2010 10:20:06 EST news201776810 Vanishing bile duct syndrome (VBDS) is an important cause of jaundice, and results from destruction of bile ducts in the liver. However, this syndrome is rare in patients with human immunodeficiency virus infection. Nevirapine, an anti-retroviral that is being increasingly used, was implicated as the cause of VBDS in a patient described in a recent report. http://phys.org/news199706046.html Medicine & Health Fri, 30 Jul 2010 12:00:07 EST news199706046 Scientists at the world AIDS conference have discussed an idea that had become almost taboo.
