Researchers find a new way to potentially thwart anthrax

In a new study, NYU School of Medicine researchers have found what may be an Achilles’ heel of deadly anthrax — a system that the bacteria use to communicate their presence to others of their kind. The researchers, Martin Blaser, M.D., the Frederick King Professor and Chairman of the Department of Medicine, and Professor of Microbiology and graduate student Marcus Jones, describe a “quorum-sensing system” in anthrax that is a type of bacterial “calling card.” Disrupting this system may open new avenues to prevention and treatment of anthrax, says Dr. Blaser.

Drug slows progression of moderate to severe Alzheimer's disease

A drug that quashes the activity of a key brain chemical is the first effective treatment for patients in the later stages of Alzheimer’s disease, according to the results of a large multi-center clinical study published in the April 3 issue of the New England Journal of Medicine. The drug, memantine, slows the mental and physical deterioration of patients with moderate to severe Alzheimer’s disease, according to Barry Reisberg, M.D., Professor of Psychiatry at NYU School of Medicine, who led the study. “These patients seem to be declining much less, about half as much as ordinarily expected, over a six-month period,” says Dr. Reisberg. “This medication will slow down the otherwise inexorable progress of this disease, and it is remarkably free of side effects. These are very impressive results. It looks like this drug really will have an impact on this disease,” he says.

Immunization may prove therapeutic for prion diseases

Researchers at NYU School of Medicine have found that immunization prolongs the incubation period for prion diseases such as Creutzfeldt-Jakob disease and may have therapeutic value for other neurodegenerative illness such as Alzheimer’s disease. Prion disease is a fatal brain disease manifested through failure of muscle control and dementia. Forms of this disease have been discovered in deer and elk (chronic wasting disease), in cows (bovine spongiform encephalopathy ? BSE ? or “mad cow disease”) and in sheep (scrapie strain).

Stem cells: From bone marrow to pancreas

Researchers have shown that cells from the bone marrow give rise to insulin-producing cells in the pancreas of mice, opening a potential new way to treat diabetes. These morphed cells actually produce the hormone insulin in response to glucose and display other characteristics demonstrating that they truly function as pancreas cells, according to a new study by NYU School of Medicine researchers.

High sugar blood levels linked to poor memory

An inability to quickly bring down high levels of sugar in the blood is associated with poor memory and may help explain some of the memory loss that occurs as we age, according to a new study by NYU School of Medicine researchers. The study raises the possibility that exercise and weight loss, which help control blood sugar levels, may be able to reverse some of the memory loss that accompanies aging.
