When a car accident or athletic injury destroys more than 20% of a muscle's mass, the body faces a problem it often can't ...

Scientists at the UCSF-affiliated Gladstone Institutes today are announcing a research breakthrough in mice that one day may help doctors restore hearts damaged by heart attacks — by converting ...

It is estimated that during a heart attack, one billion cells in the heart are lost. In the wake of the heart attack, the lost tissue is replaced by scar tissue, which can lead to heart failure, ...

Pirfenidone is currently approved for treating adults with idiopathic lung fibrosis, or scarring in the lungs that makes it hard to breathe. While the mechanism of action has not been fully ...

When someone suffers a heart attack, their heart is left permanently scarred and thus less capable of pumping blood. According to a new study, however, a protein injection could help undo such damage.

A kick in the leg from soccer can lead to a quadriceps muscle contusion. This can lead to bleeding into the muscle, a hematoma, which can result in a ball of scar tissue. RICK LOOMIS NYT Q. My 14-year ...
