Brain inflammation may be friend, not foe, for Alzheimer's patients

...a great deal of evidence that inflammation plays a potentially negative role in Alzheimer’s disease,” said O’Banion. “But much of the evidence comes from experiments with cells in a dish or postmortem human tissue, not from living organisms in which disease progression is closely monitored. “People have talke...

Research shows cord blood comparable to matched bone marrow

... with a lower risk of graft versus host disease, a potentially lethal complication, especially when HLA types are mismatched. Rates of leukemia relapse also are lower with mismatched umbilical cord blood transplants. This study also showed that in addition to having a good match, higher cell doses for umbilical ...
