Researchers regrow damaged nerves with polymer and protein

by University of Pittsburgh University of Pittsburgh School of Medicine researchers have created a biodegradable nerve guide—a polymer tube—filled with growth-promoting protein that can regenerate long sections of damaged nerves, without the need for transplanting stem cells or a donor nerve. So far, the technology has been tested in monkeys, and the results of those...

Smart antioxidant-containing polymer responds to body chemistry, environment

UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN CHAMPAIGN, Ill. — Oxidants found within living organisms are byproducts of metabolism and are essential to wound-healing and immunity. However, when their concentrations become too high, inflammation and tissue damage can occur. University of Illinois engineers have developed and tested a new drug-delivery system that senses high oxidant levels and responds by...
