Humans and Strokes  A stroke (sometimes called an acute
cerebrovascular attack) is the rapidly developing loss of brain
function(s) due to a disturbance or loss in the blood supply to
the brain. As a result, the affected area of the brain is unable
to function, leading to inability to move one or more limbs on
one side of the body, inability to understand or formulate
speech, or inability to see one side of the visual field.  Two
new studies by University of California (UC) Irvine biologists
have found that a protein naturally occurring in humans restores
motor function in rats after a stroke. Administered directly to
the brain, the protein restores 99 percent of lost movement; if
it's given through the nose, 70 percent of lost movement is
regained. Untreated rats improve by only 30 percent.  "No drugs
exist that will help a stroke after a few days. If you have a
stroke, you don't have many treatment options," said James
Fallon, psychiatry & huma
