Nanoparticle-core polymer holds promise as weight-bearing replacement for traditional graft materials

Orthopedic surgeons are often hamstrung by less-than-ideal grafting material when performing surgeries for complex bone injuries resulting from trauma, aging or cancer. Conventional synthetic bone grafts are typically made of stiff polymers or brittle ceramics, and cannot readily conform to the complex and irregular shapes that often result from injury; in addition, they often require metallic fixation devices that require open surgeries to insert and remove.

Gene therapy improve survival rates among heart attack patients

Gene therapy could be an effective way to improve survival rates among heart attack patients, new research funded by the British Heart Foundation (BHF) suggests. Academics at the University of Bristol found that boosting levels of a natural growth factor in the heart could help the muscle to recover after a heart attack. The death rate from a heart attack was halved in mice that received the treatment.

Plaques in blood vessels may break by overproducing protein-digesting enzymes

University of Washington (UW) researchers have gathered evidence that dangerous plaques in blood vessels can rupture by overproducing protein-digesting enzymes. Plaques are fat-laden rough spots in the otherwise smooth walls of arteries. When a plaque ruptures, blood accumulates inside of it, a process known as plaque hemorrhage. The plaque enlarges and artery-blocking clots can form. If the flow of oxygen-rich blood is restricted, a heart attack, stroke, or damage to other organs can occur.
