Biological mechanisms behind appetite-suppressing effects of proteins

Frequently recommended in weight-loss diets, dietary proteins have proven effectiveness thanks to their appetite-suppressing effects. A team led by Gilles Mithieux, Director of Inserm's Unit 855 "Nutrition and the Brain" in Lyon, has managed to explain the biological mechanisms behind these properties.

Prenatal exposure to PCBs impacts reproductive function in offspring

Prenatal exposure to the environmental contaminants polychlorinated biphenyls, or PCBs, causes long-term changes to the developing brain that have adverse effects on reproductive function later in life, a new study finds. Results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

Researchers discover how GLP-2 receptor suppresses hunger and food intake

Researchers have discovered how a hormone in the gut slows the rate at which the stomach empties and thus suppresses hunger and food intake. Results of the animal study will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston.

Study: Neurons that control hunger linked to non-food associated behaviors

Researchers at Yale School of Medicine have zeroed in on a set of neurons in the part of the brain that controls hunger, and found that these neurons are not only associated with overeating, but also linked to non-food associated behaviors, like novelty-seeking and drug addiction.

Investigational Insomnia Medicine from Merck improved patients’ ability to fall and stay asleep according to new phase III Data

Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced new data from two pivotal Phase III efficacy trials for suvorexant, the investigational medicine Merck is developing for the treatment of insomnia. In the studies, suvorexant significantly reduced the time it took patients to fall asleep and increased the time that patients stayed asleep as early as the first night and at the three-month time point compared to placebo. The investigational medicine met statistical significance for all primary endpoints except for one measurement at Month 3 in one of the trials. These late-breaking data were presented here today at SLEEP 2012, the 26th Annual Meeting of the Associated Professional Sleep Societies.

Researchers identify brain receptor that appears to play a central role in regulating appetite

Researchers at Columbia University Medical Center (CUMC) have identified a brain receptor that appears to play a central role in regulating appetite. The findings, published today in the online edition of Cell, could lead to new drugs for preventing or treating obesity.

GPR21 inhibitors may hold promise for diabetes

In recent years, a growing body of evidence has linked inflammation to the development of insulin resistance. In insulin resistance, the hormone insulin is less effective in promoting glucose uptake from the bloodstream into other tissues. Obesity is a major factor that contributes to insulin resistance, which can eventually lead to type 2 diabetes. Previous studies have shown that proinflammatory molecules found in fat tissue decreases sensitivity of tissues to insulin.

Hypothalamic neuropeptide changes cause obesity in low-birth-weight babies

It seems improbable that a baby born underweight would be prone to obesity, but it is well documented that these children tend to put on weight in youth if they're allowed free access to calories. Now, researchers believe they understand why this happens.

Custom-made mouthpieces can decrease levels of serum cortisol following exercise

Mouthguards are used by almost everyone participating in sports. These devices, typically purchased over-the-counter and used on the upper teeth, are designed to protect against broken teeth and an injured tongue. Recently, researchers in South Carolina found that a customized device which rests on the lower jaw can decrease levels of serum cortisol following exercise.
