A new target for painkillers
... For the study, the North Carolina co-authors tied sutures
loosely around one of each rat's two sciatic nerves to mimic nerve compression and injury from sciatica. That made the rats overly sensitive to touch on one hind paw but not the other. Each rat's sensitivity was assessed by measuring how much pressur...

made from cow or horse intestines and used in surgery to minimize scarring, is also a form of collagen. But for such a commonplace and useful protein, collagen has defied the efforts of biomedical researchers who have tried mightily to synthesize it...
UCSD study finds anthrax toxins also harmful to fruit flies
