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...

UCLA scientists store materials in cells natural vaults

... 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 ...

New technology addresses female fertility preservation

...ollicles grown individually in a three-dimensional biomaterial called alginate maintain normal connections between follicle and egg, resulting in the development of eggs, which can be fertilized and ultimately lead to healthy embryos and the birth of live mice. Previously developed methods of growing follicles o...

Finding the right mix: A biomaterial blend library

Tissue engineering for craniofacial reconstruction

...lated cells with appropriate bioactive agents in a biomaterial scaffold. It is widely recognized that scaffold architecture can profoundly influence the behavior of cells on tissue-engineering constructs. Today, during the 85th General Session of the International Association for Dental Research, scientists are...
