CLEVELAND, Sept. 13 (UPI) -- U.S. researchers are challenging the standard three-hour stroke treatment window by using bat saliva to help stroke victims avoid debilitating side effects.Stroke is the No. 1 disabling condition for adults in the United States. But Cleveland Clinic scientists say that high ranking of stroke disability is due, in part, to the limited 3-hour window physicians have to care for individuals after stroke onset.
