Researchers find far-reaching, microvascular damage in uninjured side of brain after stroke
While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports that within a ...

Finding a new way to manage infections
(Medical Xpress)—Waging an immunological war against a pathogen is not the body's only way to survive an infection. Sometimes tolerance, or learning to live with an invader, can be just as important. In tolerance the body ...
