...Francisco (13-5), which finished two games behind Atlanta in the division, lost Garrison Hearst on the first play of the game. The 1,500-yard rusher broke a bone when his left leg buckled under...
...incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations. But if efforts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power...
...could gainsay Mark McGwire. Nor could we have invented him: he was that close to perfect. He assaulted the most textured record in the most apposite sport--the sport closest to the American bone and yet most in need of a rehabilitation of the spirit. McGwire built steadily toward his moment, through 11 seasons marked by astonishing accomplishment and devastating failure. He remained at once focused on his goal and joyful in its pursuit, during which he embraced his closest rival. He never bragged, never proclaimed that he was the great white hope or the straw that stirred the drink...
First, it helps to understand that bone-marrow transplants are the most unforgiving of all transplant operations, requiring closer matches in tissue types between donors and recipients than for, say, hearts or kidneys. Because the immune system comes from the marrow, a transplant of that reddish pulp is, in effect, an immune-system transplant. There's the usual possibility that the body may reject the graft as "foreign." Then there's the almost surreal danger that the transplanted immune system will attack and kill its host...
...important stem cells that can generate a new immune system. Even better, these cells are, as doctors put it, "naive," making them less likely to attack their new host. As a result, a cord-blood transplant doesn't have to match a recipient quite so closely as a bone-marrow transplant. This experimental treatment could prove especially helpful to African-American patients and other minorities whose greater genetic diversity often means they have trouble finding a good bone-marrow match...
