Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers
...t can cause oxidative damage -- the destruction of biomaterial
due to excess oxygen -- to tissues. To protect their bodies, insects like grasshoppers discontinue breathing. "We propose that most insects stop breathing in order to lower their internal oxygen concentration to physiologically safe levels, and that...

... big challenge is how to design a package for this biomaterial
that will be compatible with living cells and will not provoke an immune reaction. Previous efforts have relied upon viruses or artificial chemicals to house and deliver drugs or other substances to targeted cells. RESEARCH: Scientists at the David ...
NJIT engineer poised to take stem cell research a step forward
... will test different scaffolds and determine which biomaterial
is the best catalyst for stem cell differentiation. Again, their hope is that stem cells can soon be used to treat patients with damaged cartilage. Arinzeh and Jaffe are collaborating on this project with Louis Rizio, MD, an orthopedic surgeon and ...
FDA approves first medical device using rutgers biomaterial
...e, the approval of the TyRx device employing a new biomaterial
represents a major breakthrough for regenerative medicine," Kohn said. The novel tyrosine-based polyarylates, as they are known chemically, arose from an adaptation of combinatorial chemistry to biomaterials. "Our approach uses two sets of starting ...
