Researchers have used injections of patients' own stem cells to reverse the course of type 1 diabetes, reports a research team from the University of São Paulo in Brazil and Northwestern University in Chicago...
...research team, led by Dr. Julio Voltarelli of the University of Sao Paulo, is the first to successfully treat type 1 diabetes patients with their own stem cells. The group first reported its initial achievement in 2007, with 15 type 1 diabetes patients who received their own stem cells and no longer needed insulin to control their blood sugar levels. In the new study, a follow-up of their previous work, Voltarelli and his colleagues detailed the same success with an additional eight patients, and also confirmed that in the majority of them, the stem cell transplant...
...idea behind the transplant is simple. In type I diabetes, the patient's own immune system turns on the beta cells that produce insulin, the hormone that breaks down the glucose we eat in food. Eventually, the immune cells will virtually eliminate all of the body's beta cells, and glucose levels will start to climb. Researchers believe that the trigger for this attack lies somewhere within the immune cells, so one possible treatment for the disease may be to wipe out the entire existing immune system and replace it with a fresh one, derived from stem cells without this...
Researchers at Harvard Medical School have discovered that adult humans do in fact possess a type of beneficial fat—previously thought to only be present in babies, young children, and other small mammals—that burns calories instead of storing them. The discovery was made simultaneously by three independent research teams in Boston, the Netherlands, Finland, and Sweden. Brown fat and its potentially crucial role in warding off obesity has since been the subject of three articles in the latest issue of the New England Journal of Medicine. Unlike its counterpart white fat, a mere two ounces...
...problem of garnering advertising revenue on to the new websites, who are already actively struggling to find a solution. With such alluring content, even that problem may evaporate more quickly. Other websites would cater to certain niches, such as gathering subscriptions and advertising for shows about doctors. This type of surgical precision in targeting high-quality viewers may allow for sustainable business models to crop...
