(Ohio State University) Researchers have identified specific damages to the brain that may occur when heart attack victims are socially isolated from others. The study in mice found that those animals that lived alone before undergoing a heart attack showed five to eight times more damage to neurons in one part of the brain than did similar animals that lived with others.

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the leading cause of heart attack and stroke. The next set of studies will seek to "tweak" the process with the goal of designing a new class of therapies.
