1/13/15 Health News AMINO ACID CURTAILS E. COLI O157 ♦ Nanotechnology guides cancer surgery ♦ FDA label likely prevents use of metformin

RESEARCH: AMINO ACID AFFECTS E. COLI O157 BEHAVIOR
New research suggests that an amino acid is what affects the behavior of E. coli O157. A University of Glasgow team analyzed the genome sequence of 1,500 strains of E. coli to see how the genes of the pathogen respond to different concentrations of D-Serine, an amino acid produced in the brain, where it plays...

Glowing' new nanotechnology guides cancer surgery, also kills remaining malignant cells
A new way to selectively insert compounds into cancer cells has been developed by scientists -- a system that will help surgeons identify malignant tissues and then, in combination with phototherapy, kill any remaining cancer cells after a tumor is removed. Ultimately, it could make cancer surgery far more effective. Continue Reading
Ouch! When teeth and hands connect, bites may be beastly
Hand injuries are frequently caused by human and animal bites, prompting as many as 330,000 emergency department visits in the United States each year. A literature review outlines the potential complications of human and animal bites to the hand, the importance of early injury assessment, and the use of antibiotic and other treatment methods to avoid infection, permanent disability, and amputation.
