Winston-Salem -- In what could be the most exciting advance in the treatment of AIDS to date, Bowman Gray School of Medicine scientists today reported a novel way to block the deadly HIV virus from ever invading white blood cells.
Scientists at Wake Forest University Baptist Medical Center report today that they have found another way to shut down the doorway for HIV-1 to invade two types of white blood cells -- lymphocytes and macrophages. In a report in the Oct 14 issue of the Proceedings of the National Academy of Sciences, Si.-Yi Chen, M.D., Ph.D., assistant professor of cancer biology, and his colleagues describe how they have inactivated the most frequently used co-receptor -- docking site -- for HIV-1 viruses on the surface of both macrophages and lymphocytes, resulting in immunity of those macrophages and lymphocytes to HIV-1 infection.

Calcium channel blockers and certain kinds of diuretics are associated with brain damage and memory loss, according to a report in today's Journal of the American Geriatrics Society -- another in a string of adverse findings about calcium channel blockers. The latest results come from an analysis of participants with high blood pressure in the Cardiovascular Health Study (CHS), the largest study ever of the natural progression of heart disease and stroke in the elderly.
New research from one of the most comprehensive studies ever of middle-age Americans indicates that people who once smoked may continue to suffer from the effects of smoking even if they had quit years before.
