Alcohol and tobacco use doesn't boost HPV-related cancer risk

Heavy smoking and drinking are known to cause head and neck cancer. Infection with human papillomavirus type 16 (HPV16), a common strain of the sexually-transmitted HPV virus, is another known risk factor for head and neck cancer, which affects about 500,000 people each year worldwide.

Cholera can be controlled with oral vaccines

Endemic cholera, a potentially fatal diarrheal disease found in the world's most impoverished countries, could be effectively controlled by orally vaccinating half of the affected populations once every two years for only pennies per dose, according to new findings by an international team of researchers led by Ira M. Longini Jr., Ph.D., a biostatistician in the Vaccine and Infectious Disease Institute at Fred Hutchinson Cancer Research Center in Seattle. Longini and colleagues will report their findings online Nov. 27 in PLoS Medicine.

Wyeth receives European approval for TORISEL

Wyeth Pharmaceuticals, a division of Wyeth, has announced that the European Commission has approved TORISEL (temsirolimus) for the first-line treatment of patients with advanced renal cell carcinoma (RCC) who have at least three of six prognostic risk factors. TORISEL is the only approved cancer therapy that specifically inhibits the mTOR (mammalian target of rapamycin) kinase, an important regulator of cell proliferation, cell growth and cell survival.

Researchers transfer immune response to myeloma patient

Researchers at the University of Arkansas for Medical Sciences (UAMS) have for the first time transferred an immune response in a healthy individual to a patient with multiple myeloma, a cancer of the bone marrow, showing promise for cancer vaccination.

New disease model for Huntington's

Huntington's disease is a genetic time bomb: Programmed in the genes, it appears at a predictable age in adulthood, causing a progressive decline in mental and neurological function and finally death.

Living donors may be best source of insulin-producing islets for diabetes treatment

According to a new study in Clinical Transplantation, obtaining islet cells (clusters of pancreatic cells that create insulin) from living donors may be a solution to the shortage of islets available for transplantation.

Flip-flopping gene expression can be advantageous

One gene for pea pod color generates green pods while a variant of that gene gives rise to the yellow-pod phenotype, a feature that helped Gregor Mendel, the 19th century Austrian priest and scientist, first describe genetic inheritance.
