Researchers develop marker that identifies energy-producing centers in nerve cells

...Prior to the development of this marker, we had no way to identify the mitochondria in neuronal cells from those in glial cells," says the study's principal investigator, Krish Chandrasekaran, Ph.D., an assistant professor in the Department of Anesthesiology at the University of Maryland School of Medici...

Rapid response was crucial to containing the 1918 flu pandemic

The ideal way to contain a potential influenza pandemic would be to vaccinate large numbers of people before they were exposed to an influenza virus strain that is easily transmitted from person to person. Developing such a vaccine in advance, however, is difficul...

Heart failure: Intervention possibilities from imaging programmed cell loss

...ng to "see" programmed cell loss—the body's normal way of getting rid of unneeded or abnormal cells—may help in early identification of those individuals who are at risk of developing heart failure, say researchers in the April Journal of Nuclear Medicine. "Our study indicates that it is feasible to non...

Transfusion expert urges wider use of filtered blood

Glucose triggers brain cell death in rats after hypoglycemic coma

...ing glucose levels is very bad for rat brains. The way we treat patients for hypoglycemia may have to be reevaluated." Swanson adds two strong cautions, however: "First, the work was done in rodents, and it is not legitimate to immediately extrapolate these findings to humans. Second, there are many w...

"Society as a whole assumes that home environments have large impacts on behavior, but studies in behavior genetics are repeatedly showing that our behavior is also influenced by our genes," says Koenig....

Aspirin discovery may improve cancer treatments

In a paper published in the prestigious Journal of Biological Chemistry in April, Professor Bryan Williams, Director of the Monash Institute of Medical Research, led a collaborative study that investigated...

Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising

...n and bruising. "We realized that we had to find a way to stop the jets from going deep into the skin," says Mitragotri. "Speeding the delivery, combined with using extremely small jet diameters and less liquid per pulsation, was shown to be more effective." ...

Mutation improves memory, may lead to memory-enhancing pill
