Leptin found to control appetite and limb development in frogs
Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus. As it does in humans and other mammals, leptin acts on the frog brain to suppress appetite. But the hormone also seems to play a role in the complex signaling that turns a finned tadpole into a fou...How appetite-stimulating brain cells work overtime during fasting
During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active. The researchers revealed a link between active thyroid hormone in the brain and increase...Hormone restrains appetite in man
According to reasearchers, a hormone is released into the blood after a meal, restrain the appetite if given by injection and might be supportive in treating obesity. The reason for feeling full after a meal, that the intestines release a hormone called PYY3-36 //which acts on the brain to produce a feeling of satiety. Researchers at Imperial College, London, now report on the first human trial...Scientists locate key hormone involved in appetite control
A key hormone involved in appetite control, called ghrelin, has been identified by researchers from the Oregon Health & Science University(OHSU). Scientists have demonstrated the effect of the hormone on the brain and have shown that the hormone activated the specialized neurons in the hypothalamus involved in weight regulation. Ghrelin is a hormone produced in the stomach with the ability to sti...Extra hormone found to cut appetite by a third
Studies done previously have shown that the hormone could suppress the appetites of lean people. But researchers were worried it would not work in obese people because studies of another appetite-suppressing hormone,// leptin, had proved disappointing. "We had to do a second trial to see if obese people were as sensitive" to the hormone, said researchers. The answer: "Yes, they are. The...The Reason For Loss Of Appetite After Gastric Bypass
Researchers now say they might have a partial explanation for the loss of hunger and rapid weight loss observed after gastric bypass surgery.// In the gastric bypass procedure, the stomach is divided to create a pouch out of the small proximal portion of the stomach, which is then attached to the small intestine, bypassing a large part of the stomach and all of the duodenum. It was found...
