t using surgery, he said. A safe, effective, non-surgical means to eliminate undesirable body fat would be of great benefit to our patients.
Roxanne Guy, MD, president of the American Society of Plastic Surgeons, of which Baker is a member, is also excited by the findings, although she agrees that more research is needed to find out how the animal findings translate in humans.
Providing a long lasting, natural wrinkle filler and a scientifically studied, non-surgical method for melting fat could revolutionize growing old gracefully, she said. This discovery could also have positive implications for reconstructive plastic surgery procedures performed on the face and breasts.
Stress + comfort foods = excess weight gain
As part of the study, Zukowska and her team examined the effect of several forms of chronic stress that mice in the wilderness can encounter, such as exposure for an hour a day over a two-week period to standing in a puddle of cold water or to an aggressive alpha mouse, and they conducted the experiments in combination with a regular diet or with a high-fat, high-sugar diet.
Stressed animals fed a normal diet did not gain weight, but stressed mice given a high-fat diet did. In fact, the researchers found these mice put on more weight than expected given the calories they were consuming.
They gained twice as much fat as would be expected, and it was all in their belly area, Kuo said. Stressed versus non-stressed animals ate the same amount of food, but the stressed animals processed it differently, she said, explaining, the novel finding here is that NPY works on fat tissue, not in the brain.
This finding makes sense if evolutionary advantage is considered, Zukowska said. If you can store fat for times of hardship, you have a fat reserve that can be turned into energy for the next fight.
The same mechanism may be happening in humans, she said. An accumulaPage: 1 2 3 4 Related medicine news :1
