And this anniversary brings fresh hope for something many had come to think was impossible: finding a cure. http://phys.org/news226292494.html Medicine & Health - HIV & AIDS 2011-06-03T04:20:01-07:00 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 - HIV & AIDS 2011-06-02T18:40:01-07:00 (AP) -- When AIDS counselor Patience Ncusani urges teens in her Soweto neighborhood to wait to have sex, or cautions young women that an older boyfriend can be deadly, she has special rapport. http://phys.org/news226140115.html Medicine & Health - HIV & AIDS 2011-06-01T09:42:12-07:00 On June 5 1981, American epidemiologists reported a baffling event: five young gay men in Los Angeles, all previously healthy, had fallen ill with pneumonia. Two had died. http://phys.org/news225886499.html Medicine & Health - HIV & AIDS 2011-05-29T11:17:09-07:00 The US Food and Drug Administration on Friday approved a new drug, Edurant, to fight HIV in combination with other antiretrovirals already on the market. http://phys.org/news225180327.html Medicine & Health - HIV & AIDS 2011-05-21T07:05:44-07:00 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 - HIV & AIDS 2011-05-04T14:29:17-07:00 Thanks to a certain protein, rhesus monkeys are resistant to HIV. Known as TRIM5, the protein prevents the HI virus from multiplying once it has entered the cell. Researchers from the universities of Geneva and Zurich have now discovered the protein's mechanism, as they report in Nature. This also opens up new prospects for fighting HIV in humans. http://phys.org/news222523456.html Medicine & Health - HIV & AIDS 2011-04-20T13:04:32-07:00 A trial of an oral pill aimed at preventing HIV infection in African women has been halted due to poor results, the trial operator Family Health International announced this week. http://phys.org/news222439478.html Medicine & Health - HIV & AIDS 2011-04-19T14:10:01-07:00 Researchers are stopping a study that tests a daily pill to prevent infection with the AIDS virus in thousands of African women because partial results show no signs that the drug is doing any good. http://phys.org/news222342982.html Medicine & Health - HIV & AIDS 2011-04-18T10:56:49-07:00 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 - HIV & AIDS 2011-04-05T16:25:46-07:00 A section of the AIDS virus's protein envelope once considered an improbable target for a vaccine now appears to be one of the most promising, new research by Dana-Farber Cancer Institute scientists indicates. http://phys.org/news220813047.html Medicine & Health - HIV & AIDS 2011-03-31T17:58:18-07:00 (PhysOrg.com) -- An international study headed by a UC Davis scientist describes how a component of a potential HIV vaccine opens like a flower, undergoing one of the most dramatic protein rearrangements yet observed in nature. The finding could reveal new targets for vaccines to prevent HIV infection and AIDS. A paper describing the work was published online this week in the journal Proceedings of the National Academy of Sciences. http://phys.org/news220775356.html Medicine & Health - HIV & AIDS 2011-03-31T08:20:01-07:00 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 - HIV & AIDS 2011-03-31T08:15:06-07:00 If Congress reversed its ban on allowing people with HIV to be organ donors after their death, roughly 500 HIV-positive patients with kidney or liver failure each year could get transplants within months, rather than the years they currently wait on the list, new Johns Hopkins research suggests. http://phys.org/news220703102.html Medicine & Health - HIV & AIDS 2011-03-30T11:25:31-07:00 In the Faculty of Nursing, students are taught the importance of connecting with the community, and nursing professor Vera Caine has come up with a way for students to not only learn about working in the community, but also to actually be a part of it. http://phys.org/news220693274.html Medicine & Health - HIV & AIDS 2011-03-30T08:41:43-07:00 Genetic mutations that lead to antiretroviral (the drugs used to treat HIV/AIDS) resistance in HIV-infected infants may develop as a result of exposure to low doses of maternal antiretroviral drugs via breastfeeding rather than being acquired directly from the mother. This key finding from a study by Clement Zeh from the US Centers for Disease Control and Prevention, Kisumu, Kenya, and colleagues, published in this week's PLoS Medicine, is important as it may impact the choice of drug regimen given to HIV-infected breastfeeding mothers and their infected infants—an effective intervention which has been shown to substantially reduce the overall rate of mother-to-child transmission of the HIV virus. http://phys.org/news220638859.html Medicine & Health - HIV & AIDS 2011-03-29T17:34:37-07:00 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 - HIV & AIDS 2011-03-25T09:40:03-07:00 A number of American men who have sex with men are supportive of couples-based voluntary HIV counseling and testing (CVCT), in which couples receive counseling and their HIV test results together, according to a new study by Dr. Rob Stephenson from Rollins School of Public Health in Atlanta, USA, and his colleagues. The authors argue that there may be a demand among gay men for this effective strategy, used in Africa amongst heterosexual couples, albeit with some adaptations to the protocol to make it relevant in the US. The work is published online in Springer's journal, AIDS and Behavior. http://phys.org/news220182907.html Medicine & Health - HIV & AIDS 2011-03-24T10:55:28-07:00 Biochemist Leor Weinberger and colleagues at the University of California, San Diego and UCLA have proposed a fundamentally new intervention for the HIV/AIDS epidemic based on engineered, virus-like particles that could subdue HIV infection within individual patients and spread to high-risk populations that are difficult for public health workers to reach. http://phys.org/news219601908.html Medicine & Health - HIV & AIDS 2011-03-17T17:32:09-07:00 (AP) -- A transplant patient contracted AIDS from the kidney of a living donor, in the first documented case of its kind in the U.S. since screening for HIV began in the mid-1980s. http://phys.org/news219589359.html Medicine & Health - HIV & AIDS 2011-03-17T14:02:57-07:00 Oral disease occurs commonly and progresses rapidly among people who have HIV, but the process is poorly understood. Researchers suspect that the culprit is a change in the makeup of bacterial communities that live in the mouth. http://phys.org/news219568629.html Medicine & Health - HIV & AIDS 2011-03-17T08:17:44-07:00 A research article co-authored by Brenna Anderson, MD, director of Reproductive Infectious Diseases Consultation in the Division of Maternal-Fetal Medicine at Women & Infants Hospital of Rhode Island, was included in the recently published special issue of the American Journal of Reproductive Immunology. http://phys.org/news219491085.html Medicine & Health - HIV & AIDS 2011-03-16T10:44:59-07:00 A team of Indonesian and Australian researchers has developed a new computerised tool to help authorities reduce HIV infection and track disease burden across the Indonesian archipelago. http://phys.org/news219394335.html Medicine & Health - HIV & AIDS 2011-03-15T07:52:32-07:00 Elevated levels of p21, a protein best known as a cancer fighter, may be involved in the ability of a few individuals to control HIV infection with their immune system alone. In a paper in the April edition of the Journal of Clinical Investigation, researchers from the Massachusetts General Hospital (MGH) Infectious Disease Division and the Ragon Institute of MGH, MIT and Harvard report that CD4 T cells from HIV controllers, while capable of being infected, can effectively suppress key aspects of the viral life cycle, an ability that may be associated with increased expression of the p21 protein. Preliminary results of this study were presented at the October 2010 Infectious Diseases Society of America meeting. http://phys.org/news219325232.html Medicine & Health - HIV & AIDS 2011-03-14T12:41:18-07:00
