Inexpensive generic medicines are a large part of the solution, say researchers from Brown University and the Harvard School of Public Health. http://phys.org/news166771848.html Medicine & Health Tue, 14 Jul 2009 06:40:02 EST news166771848 One of the continuing mysteries of the HIV/AIDS epidemic is why women usually develop lower viral levels than men following acute HIV-1 infection but progress faster to AIDS than men with similar viral loads. Now a research team based at the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard has found that a receptor molecule involved in the first-line recognition of HIV-1 responds to the virus differently in women, leading to subsequent differences in chronic T cell activation, a known predictor of disease progression. Their paper, which will be published in an upcoming issue of Nature Medicine, is receiving early online release. http://phys.org/news166711709.html Medicine & Health Mon, 13 Jul 2009 13:48:55 EST news166711709 The American Physical Therapy Association (APTA) is urging elderly adults who use canes and walkers as walking aids to be properly assessed and fitted by a physical therapist to avoid fall-related injuries. This advice comes in response to a study published in the Journal of the American Geriatrics Society (June 2009), which found that 47,000 senior citizens end up in emergency rooms each year due to falls from improper use and fit of walkers and canes. http://phys.org/news166455897.html Medicine & Health Fri, 10 Jul 2009 14:45:31 EST news166455897 The virus that causes AIDS is classified as a lentivirus, a word derived from the Latin prefix, "lenti-," meaning "slow." But new research from the NIAID-funded Center for HIV/AIDS Vaccine Immunology suggests that HIV-1 is anything but - moving at breathtaking speed in destroying and dysregulating the body's gut-based B-cell antibody-producing system. http://phys.org/news166161662.html Medicine & Health Tue, 07 Jul 2009 05:01:24 EST news166161662 (AP) -- A new Internet data map offers a first-of-its-kind, county-level look at HIV cases in the U.S. and finds the infection rates tend to be highest in the South. http://phys.org/news164898312.html Medicine & Health Mon, 22 Jun 2009 14:05:53 EST news164898312 Researchers from the newly-established VGTI Florida and the University of Montreal have uncovered a possible method for eradicating HIV infection in the human body. The researchers have also revealed new information which demonstrates how HIV persists in the body - even in patients receiving drug treatments - and how the virus continues to replicate itself in individuals undergoing treatment. The research findings will be published in the online version of the journal Nature Medicine on June 21 and will be featured in an upcoming print edition of the journal. http://phys.org/news164809422.html Medicine & Health Sun, 21 Jun 2009 17:30:01 EST news164809422 A discovery by a team of Canadian and American researchers could provide new ways to fight HIV-AIDS. According to a new study published in Nature Medicine, HIV-AIDS could be treated through a combination of targeted chemotherapy and current Highly Active Retroviral (HAART) treatments. This radical new therapy would make it possible to destroy both the viruses circulating in the body as well as those playing hide-and-seek in immune system cells. http://phys.org/news164809253.html Medicine & Health Sun, 21 Jun 2009 13:21:22 EST news164809253 Many drugs commonly prescribed to older adults for a variety of common medical conditions including allergies, hypertension, asthma, and cardiovascular disease appear to negatively affect the aging brain causing immediate but possibly reversible cognitive impairment, including delirium, in older adults according to a clinical review now available online in the Journal of Clinical Interventions in Aging, a peer reviewed, open access publication. http://phys.org/news163075705.html Medicine & Health Mon, 01 Jun 2009 11:48:55 EST news163075705 Those in the United States living with HIV/AIDS are more likely to use marijuana than those in Kenya, South Africa or Puerto Rica to alleviate their symptoms, according to a new study published in Clinical Nursing Research, published by SAGE. Those who did use marijuana rate it as effective as prescribed or over the counter (OTC) medicines for the majority of common symptoms, once again raising the issue that therapeutic marijuana use merits further study and consideration among policy makers. http://phys.org/news162814169.html Medicine & Health Fri, 29 May 2009 11:10:00 EST news162814169 (AP) -- The push to legalize medical marijuana in Illinois has taken a big step forward. http://phys.org/news162707564.html Medicine & Health Thu, 28 May 2009 05:33:04 EST news162707564 Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions. http://phys.org/news162670146.html Medicine & Health Wed, 27 May 2009 19:21:49 EST news162670146 A research team may have broken the stubborn impasse that has frustrated the invention of an effective HIV vaccine, by using an approach that bypasses the usual path followed by vaccine developers. By using gene transfer technology that produces molecules that block infection, the scientists protected monkeys from infection by a virus closely related to HIV—the simian immunodeficiency virus, or SIV—that causes AIDS in rhesus monkeys. http://phys.org/news161786789.html Medicine & Health Sun, 17 May 2009 13:47:15 EST news161786789 HIV-positive patients who don't seek medical attention until they have a serious AIDS-related condition can reduce their risk of death or other complications by half if they get antiretroviral treatment early on, according to a new multicenter trial led by researchers at the Stanford University School of Medicine. http://phys.org/news161677478.html Medicine & Health Sat, 16 May 2009 07:25:11 EST news161677478 (AP) -- The Obama White House said Tuesday that it wants $63 billion to be set aside in the fiscal 2010 budget to fight global diseases over the next six years. http://phys.org/news160755172.html Medicine & Health Tue, 05 May 2009 15:13:30 EST news160755172 Infection with anal human papillomavirus (HPV), a virus that can cause anal and cervical cancers, is associated with a higher risk of new HIV infection in previously HIV-negative men who have sex with men (MSM), according to new UCSF research. http://phys.org/news160330706.html Medicine & Health Thu, 30 Apr 2009 17:18:59 EST news160330706 Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled. The reason? According to new findings from a team of researchers from the California Institute of Technology (Caltech), it's at least partly due to the fact that our body's natural HIV antibodies simply don't have a long enough reach to effectively neutralize the viruses they are meant to target. http://phys.org/news159630488.html Medicine & Health Wed, 22 Apr 2009 14:49:15 EST news159630488 The "humanized mouse" developed by Dr. J.
