...cancer patients who need bone-marrow transplants may now have a larger pool of potential donors. Israeli and Italian doctors say they have vastly improved the odds of a successful transplant between family members whose tissue types don't match perfectly. It's done by transplanting large numbers of stem cells--the bone-marrow cells that make blood. In Japan, doctors report that sophisticated DNA analysis is enabling them to better match donors and recipients who are not related...
...They tied him to a post," says police commander Dave O'Malley, and as he begged for his life, they "beat him and beat him." Perhaps as an afterthought, police say, the pair took Shepard's wallet and his shoes. The back of his head bashed to the brain stem, his face cut, his limbs scorched with burn marks, Shepard hung spread-eagled on a rough-hewn deer fence through a night of near freezing temperatures, unconscious and losing more and more blood. On the evening of the next day, 18 hours after he was abandoned, two bicyclists...
...true Canadian style, the actual physical differences between the American and Canadian ways of celebrating are minor. Both are opportunities for family and friends to get together over the same traditional Thanksgiving cannon of turkey, stuffing, cranberries and mashed potatoes. The similarities stem from the fact that the holiday was originally American and only became a Canadian event after it was established in the U.S. Ryan D. Steingard '00, originally from Victoria, does not let this fact disturb him. "The U.S. had the original Thanksgiving, but we're just thankful were not Americans," he says...
Technicians drain the afterbirth of its blood and process the material to concentrate the stem cells. Theoretically, stem cells can rebuild the body's bloodmaking machinery so that it produces the full array of effective blood cells the body needs to defend itself against germs, close wounds and transport oxygen. Scientists speculate that cord stem cells are more adaptable and will transplant more successfully, even in patients with imperfect biological matches, than stem cells harvested from adult bone-marrow donors...
When doctors are confident the sick cells have been destroyed, the cord cells are dripped into the children's arms. The lucky ones wait up to 100 days for their stem cells to start functioning. The cost to save a child's life...
