Plastic surgeons countdown first full facial transplantation

...cine," said Dr. Cunningham. "The first successful hand transplantation was performed by a plastic surgeon in 1998, as was the first kidney transplant in 1954. The idea of tissue transplantation has opened a new era in this field of medicine." ...

Robot assisted surgery more accurate than conventional surgery

...: "These robots are designed to hold the surgeon's hand in the operating theatre, not take over the operation. This study shows they can be an enormous help, preventing surgeons from making mistakes. More importantly, by showing how the increased accuracy makes a difference to how well a knee works after ...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...erstanding of craniofacial development, right-left hand preference, right/left brain dominance and a variety of birth defects in humans. A team of Forsyth Institute scientists, led by Michael Levin, PhD, Director of the Forsyth Center for Regenerative and Developmental Biology, examined the molecular an...

Cheaper and simpler keyhole surgery

Unfortunately, the efficacy of such strategies in preventing the spread of infectious diseases has not been extensively studied, Bruine de Bruin said. Although the federal government has expressed a commit...

Scientists design potent anthrax toxin inhibitor

...polyvalent. Just as a glove matches the shape of a hand more closely than a mitten, and so fits more snugly, the polyvalent inhibitor binds the toxin at multiple sites and is orders of magnitude more potent than an inhibitor that binds at a single site. The multiple peptides on the functionalized liposome...
