A study that will appear in the September 1 issue of The Journal of the American Medical Association (JAMA) reports that women with these inherited mutations who have had a prophylactic mastectomy or salpingo-oophorectomy (removal of the fallopian tubes and ovaries) had an associated decreased risk of breast cancer and ovarian cancer.

Och University Professor at the University of Pennsylvania, and colleagues Danny Reinberg, PhD, New York University, and Juergen Liebig, PhD, Arizona State University, have established an important new avenue of research for epigenetics -- the study of how the expression or suppression of particular genes affects an organism's characteristics, development, and even behavior.
Despite the fact that an estimated 25 million patients per year in the U.S. undergo surgeries using general anesthesia, scientists have only been able to hypothesize exactly how anesthetics interact with the central nervous system. They previously thought that the processes of “going under” and waking up from anesthesia affected the brain in the same way.
