Blood Transfusions Raise Infection And Death RiskBlood transfusions save the lives of millions of heart surgery patients and others each year. But a new study suggests that patients who receive transfusions during heart bypass surgery have a higher risk of developing potentially dangerous infections, and dying, after their operation.
In fact, this increased risk may help explain a longstanding medical mystery: why women bypass patients are more likely than men to die in the first few........Go to the Infectious disease blog (Added on 12/20/2006 4:28:03 AM)

Challenging The Theory Of Memory StorageDaily events are minted into memories in the hippocampus, one of the oldest parts of the brain. For long-term storage, researchers think that memories move to the neocortex, or "new bark," the gray matter covering the hippocampus. This transfer process occurs during sleep, particularly during deep, dreamless sleep.
A number of neuroresearchers have embraced and built upon this theory of memory storage, or consolidation, for a generation. But........Go to the Neurology news blog (Added on 12/11/2006 4:57:23 AM)
