For injection drug users, the most productive and cost-effective approach to managing the spread of HIV is expanding syringe exchange and drug treatment, as well as promoting antiretroviral treatment for those already infected with HIV, according to a new study by researchers at Yale School of Medicine.
Testing for deadly food, air and water pathogens may get a lot easier and cheaper thanks to the work of a Michigan State University researcher and his team. Syed Hashsham, an associate professor in the Department of Civil and Environmental Engineering and the Center for Microbial Ecology, is developing a portable, hand-held device capable of detecting up to 50 microbial threat agents in air, water and food
Symptoms of heart disease and diabetes usually seen in adults are increasingly being found in adolescents according to a longitudinal study, which suggests that reducing the intake of sugar-sweetened beverages during childhood may lessen the risk of chronic disease in later life.
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial “progenitor” stem cells persist in the aging brain.
Research at the University of Liverpool has found that Shakespearean language excites positive brain activity, adding further drama to the bard’s plays and poetry
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon.
The latest Gamma Knife? technology is now available at Cedars-Sinai with the opening of the Gamma Knife Center at the Samuel Oschin Comprehensive Cancer Institute.
An effective response of the immune system’s “killer” T cells against infection with HIV may depend on exactly which viral protein is targeted, according to an international group of researchers. A new study finds that HIV-infected individuals in whom virus-specific CD8 T cells are targeted against the Gag protein have lower viral levels than do those with CD8 responses directed against other viral proteins.
The number of people living with HIV in the Middle East and North Africa has risen to 460,000 and some 68,000 people were newly infected in 2006 alone. In a bid to curb the region?s growing epidemic, countries have been working with UNAIDS to secure additional funding to scale-up the AIDS response in the region.
A diagnostic device that resembles a mammography unit can detect breast tumors as tiny as one-fifth of an inch in diameter, which may make it a valuable complementary imaging technique to mammography, say researchers at Mayo Clinic, who helped develop the technology along with industry collaborators Gamma Medica and GE Healthcare.
