Engineered biomaterial could improve success of medical implants

Expensive, state-of-the-art medical devices and surgeries often are thwarted by the body's natural response to attack something in the tissue that appears foreign. Now, University of Washington engineers have demonstrated in mice a way to prevent this sort of response.

Reversing paralysis with a restorative gel

A team of Tel Aviv University researchers, led by Dr. Shimon Rochkind and Prof. Zvi Nevo, has invented a method for repairing damaged peripheral nerves using a biodegradable implant along with a newly-developed gel that increases nerve growth and healing, ultimately restoring function to a torn or damaged nerve. The therapy is only a few years away from clinical use, say the researchers.

A trick to fold proteins more quickly

A team of researchers of the International School for Advanced Studies (SISSA) of Trieste and of University of Cambridge have devised a method to reduce the time used to simulate how proteins take on their signature three-dimensional shape. Such important information to comprehend their function is usually obtained using often very costly experimental techniques.

Silk and cellulose biologically effective for use in stem cell cartilage repair

Over 20 million people in Europe suffer from osteoarthritis which can lead to extensive damage to the knee and hip cartilage. Stem cells offer a promising way forward but a key challenge has been to design a 'smart material' that is biologically effective for cartilage tissue regeneration. Now researchers have identified a blend of naturally occurring fibers such as cellulose and silk that makes progress towards affordable and effective cell-based therapy for cartilage repair a step closer.
