The investigators also exposed cultured mouse and monkey hepatocytes to TRAIL but found that this compound did not trigger cell death, thus confirming results of earlier whole-animal studies.

... decade physicians have come to realize that a few hours of sweating away water and salt, but drinking only water, could put some runners into a danger zone known as hyponatremia. It was found that some runners who collapsed and died during a marathon had lost the normally well-balanced ratios of salt and...Nanofabricated 'gel' separates DNA
