Penn study finds hyperbaric oxygen treatments mobilize stem cells

According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body. Stem cells, also called progenitor cells are crucial to injury repair. The study currently appears on-line and is scheduled for publication in the April 2006 edition of the American Journal. more

Researchers discover how a high-fat diet causes type 2 diabetes 

Howard Hughes Medical Institute researchers have discovered a molecular link between a high-fat, Western-style diet, and the onset of type 2 diabetes. In studies in mice, the scientists showed that a high-fat diet disrupts insulin production, resulting in the classic signs of type 2 diabetes. more

Positive outcome of Medicare drug benefit

An editorial by Richard Platt, professor and chair of the Department of Ambulatory Care and Prevention (of Harvard Medical School and Harvard Pilgrim Health Care), says that an unintended effect of the Medicare Drug Benefit could be the creation of the world's most valuable resource for understanding how drugs are used, as well as their risks and benefits, especially among the elderly and chronically ill. This article appears in the Dec. 29 New England Journal of Medicine. more
