HIV
Killed or disabled viruses have proven safe and effective for vaccinating billions worldwide against smallpox, polio, measles, influenza and many other diseases.
But killed or severely "attenuated" vaccines, which are safer than "live" vaccines, have been largely unsuccessful for many non-viral diseases, including illnesses like tuberculosis and malaria.
(Rockville, MD) -- For the first time, researchers have experimentally induced antibodies that neutralize HIV-1 and simultaneously recognize both HIV-1 envelope protein and lipids. The results were reported by U.S. Military HIV Research Program (MHRP) researchers on Aug. 25 in the online version of AIDS, the official journal of the International AIDS Society.
New research from UCSF examining HIV among men who have sex with men (MSM) in the township of Soweto in South Africa has found that a third of gay-identified men are infected with HIV.
Patients infected with a particular subtype of HIV, the virus that causes AIDS, are more likely to develop dementia than patients with other subtypes, a study led by Johns Hopkins researchers shows.
ANN ARBOR, Mich.---Allowing teens to work too many hours in the wrong environment can be dangerous for their sexual health by fostering conditions that lead them to older sex partners, a new study shows.
Organic and Natural Beef Cattle Production Systems Offer No Major Difference in Antibiotic Susceptibility of E. coli
MADISON -- Success in soccer sometimes comes with "bending it like Beckham." Success in cellular fusion -- as occurs at the moment of conception and when nerve cells exchange neurotransmitters -- requires that a membrane be bent before the merging process can begin, University of Wisconsin-Madison researchers have shown.
MADISON -- With the help of the human immunodeficiency virus (HIV) and molecular engineering, researchers have designed synthetic protein-like mimics convincing enough to interrupt unwanted biological conversations between cells.
WASHINGTON, Aug. 16, 2009 -- The first dry powder inhalable vaccine for measles is moving toward clinical trials next year in India, where the disease still sickens millions of infants and children and kills almost 200,000 annually, according to a report presented here today at the 238th National Meeting of the American Chemical Society (ACS).
Arlington, Va. -- With HIV patients living longer thanks to advances in treatment, the primary care needs of those living with HIV have never been more important. Updated, evidence-based guidelines from the HIV Medicine Association (HIVMA) and the Infectious Diseases Society of America (IDSA) are designed to help providers manage the care of those living with this complex chronic infection.
SALT LAKE CITY, Aug. 10, 2009 -- University of Utah scientists developed a new kind of "molecular condom" to protect women from AIDS in Africa and other impoverished areas. Before sex, women would insert a vaginal gel that turns semisolid in the presence of semen, trapping AIDS virus particles in a microscopic mesh so they can't infect vaginal cells.
Researchers at the Yerkes National Primate Research Center, Emory University, believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine.
PHILADELPHIA -- (August 6, 2009) -- A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.
Irvine, Calif. -- Researchers have identified what they believe is the original source of malignant malaria: a parasite found in chimpanzees in equatorial Africa.
A member of a new class of antiretroviral drugs is safe and effective for patients beginning treatment against HIV, according to researchers who have completed a two-year multisite phase III clinical trial comparing it with standard antiretroviral drugs.
The results are online and scheduled for publication in an upcoming issue of the Lancet.
