It is apparent that in human beings the brain’s reward program helps to regulate food intake said Frank. The precise role of these systems in consuming disorders such as for example anorexia nervosa and, conversely, obesity, remains unclear. .. CU scientist talks about prize circuits in the mind Why does one person become anorexic and another obese? A study recently published by a University of Colorado College of Medicine researcher demonstrates reward circuits in the mind are sensitized in anorexic women and desensitized in obese women. The findings also suggest that eating behavior relates to mind dopamine pathways involved in addictions. Guido Frank, MD, associate professor director of the Developmental Mind Research Program at the CU College of Medicine and his colleagues used useful magnetic resonance imaging to examine human brain activity in 63 females who had been either anorexic or obese.Among other activities, researchers could determine how infections invade a cell or how proteins operate in the body. Such technology also could help doctors pinpoint the precise location of cancer cells to be able to better focus treatment and minimize damage to healthy cells. Outside the physical body, the technology may help increase detection of such poisons as anthrax. The key to developing single-molecule tracking technology might be the development of better fluorescent nanoparticles. Fluorescent nanoparticles are a large number of times smaller than the width of a individual hair and are similar in size to protein molecules, to which they could be attached.
