...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 led to an appreciable repopulation of functioning insulin-producing beta cells in the pancreas...
...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...
...marrow of each diabetes patient. Then each person was treated with radiation, similar to the regimen that cancer patients receive, in order to destroy the immune system. Afterward, each patient received his own stem cells back by injection. The scientists traced blood levels of a protein, C-peptide, that beta cells produce, in order to confirm that whatever remaining beta cells the patient had were now able to grow again and repopulate the pancreas - and produce insulin. Sure enough, levels of C-peptide rose in 20 of the 23 patients; 12 were able to stay off insulin therapy for three...
Twenty-four juniors have been elected to Alpha Iota of Massachusetts, Harvard’s chapter of Phi Beta Kappa. The undergraduate honor society, whose stated goal is to encourage “scholarship, friendship, and cultural interests,” admits students based on factors such as the variety of their course loads and the depth of their intellectual endeavors. The application process includes submitting two letters of recommendation, which the society recommends be written by faculty members at the University. The inducted students said that they were very pleased with their prestigious achievement...
