Stroke victims have new hope with activated protein C

...niversity of Rochester, New York suggests that the activated protein C (APC), a protein with anti-inflammatory and anti-coagulant properties,which until now is being used to treat septic infections, may also help reduce the damage caused by stroke. Researchers who conducted the study on mice found that APC cou...

Scientists locate key hormone involved in appetite control
