Excess maternal weight gain predicts high birth weight: Research

Expectant mothers who gain large amounts of weight tend to give birth to heavier infants who are at higher risk for obesity later in life. But it's never been proven that this tendency results from the weight gain itself, rather than genetic or other factors that mother and baby share. A large population-based study from Children's Hospital Boston, looking at two or more pregnancies in the same mother, now provides evidence that excess maternal weight gain is a strong, independent predictor of high birth weight.

FSU biologist-mathematician team receives $2.64 million grant to study prolactin secretion

A Florida State University biologist and mathematician have joined forces to find out exactly how the brain oversees the secretion of the hormone prolactin from the pituitary gland, research that could lead to new ways to treat hundreds of disorders, including infertility.

Increased SIRT1 protein can delay delay aging, extend lifespan

Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.

PI3 kinase boosts body heat, helps burn excess calories

New findings by UT Southwestern Medical Center researchers suggest that an enzyme in the brain known as PI3 kinase might control the increased generation of body heat that helps burn off excess calories after eating a high-fat meal.

POMC neurons suppress appetite, induce weight loss: Research

A protein found in cells throughout the body must be present in a specific set of neurons in the brain to prevent weight gain after chronic feeding on high-calorie meals, new findings from UT Southwestern Medical Center researchers suggest.

Eisai to commercialize lorcaserin for obesity and weight management in U.S.

Arena Pharmaceuticals, Inc. today announced that Eisai Inc. will market lorcaserin for obesity and weight management in the United States following U.S. Food and Drug Administration (FDA) approval under the terms of a marketing and supply agreement between Arena Pharmaceuticals GmbH, a wholly owned subsidiary of Arena Pharmaceuticals, Inc., and Eisai. Lorcaserin, which Arena discovered and has developed for weight management, is intended for obese patients as well as overweight patients who have at least one weight-related co-morbid condition.

Eisai signs agreement with Arena Pharmaceuticals GmbH to commercialize lorcaserin

Eisai Inc., the U.S. pharmaceutical operation of Tokyo-based Eisai Co., Ltd., announced today that it has entered into an agreement with Arena Pharmaceuticals GmbH, a wholly owned subsidiary of Arena Pharmaceuticals, Inc., for exclusive U.S. rights to commercialize lorcaserin, a drug candidate for potential use in the treatment of obesity, including weight loss, for patients who are obese (Body Mass Index or BMI ≥ 30) or overweight (BMI ≥ 27) with at least one weight-related co-morbid condition.

Arena's lorcaserin reduces body weight across patient subgroups

Arena Pharmaceuticals, Inc. today reported pooled Week 52 data from more than 6,000 patients in lorcaserin's pivotal Phase 3 clinical trial program that demonstrate lorcaserin 10 mg dosed twice daily reduced body weight in all patient subgroups evaluated, as defined by gender, age, ethnicity and starting body weight and Body Mass Index (BMI). Greater improvements in cardiovascular risk factors were also achieved with lorcaserin treatment compared to placebo overall and in most subgroups.

Many Huntington's disease patients suffer from weight loss, sleeping problems

An aggregating protein causes many of the symptoms of Huntington's disease, an incurable and frequently fatal brain disorder. Mosaic winner Ahmad Aziz discovered that the abnormal protein also aggregates in the hypothalamus, the part of the brain that regulates the autonomic nervous system and the endocrine system.

Merck's MK-4305 improves overall sleep efficiency in primary insomnia patients

Clinical results from a Phase IIb study showed that MK-4305, Merck's investigational dual orexin receptor antagonist, was significantly more effective than placebo (p<0.005) in improving overall sleep efficiency at night one and at the end of week four in patients with primary insomnia. MK-4305 was generally well-tolerated in the study. Orexins are neuropeptides (chemical messengers) that are released by specialized neurons in the hypothalamus region of the brain and are believed to be an important regulator of the brain's sleep-wake process.

Hunger-signaling hormone ghrelin regulates circulation of cholesterol in brain

Circulation of cholesterol is regulated in the brain by the hunger-signaling hormone ghrelin, researchers say. The finding points to a new potential target for the pharmacologic control of cholesterol levels.

Researchers generate the first comprehensive genetic parts list of mouse hypothalamus

A Johns Hopkins and Japanese research team has generated the first comprehensive genetic "parts" list of a mouse hypothalamus, an enigmatic region of the brain — roughly cherry-sized, in humans — that controls hunger, thirst, fatigue, body temperature, wake-sleep cycles and links the central nervous system to control of hormone levels.

New breakthrough may help understand human obesity and eating disorders

A nutrient that's common to all living things can make hibernating marmots hungry - a breakthrough that could help scientists understand human obesity and eating disorders, according to a new study by a Colorado State University biologist.

Abnormal androgen signaling in ovaries cause female infertility

Male sex hormones, such as testosterone, have well defined roles in male reproduction and prostate cancer. What may surprise many is that they also play an important role in female fertility. A new study finds that the presence and activity of male sex hormones in the ovaries helps regulate female fertility, likely by controlling follicle growth and development and preventing deterioration of follicles that contain growing eggs.

Hormone-like inner ear signaling system protects against noise-induced hearing loss

An in vivo study shows for the first time that there is a stress-response system within the cochlea that mirrors the signaling pathways of the body's fight or flight response. Researchers have identified a hormone-like signaling system of the inner ear that sets baseline hearing sensitivity and helps protect against noise-induced hearing loss.

Invida to distribute and promote Ipsen's Diphereline, Somatuline Autogel and Increlex in South-East Asia

Ipsen, a global biopharmaceutical group, and Invida Group, the leading healthcare commercialization solutions partner in the Asia Pacific region, announced today an agreement for the exclusive distribution and promotion by Invida of Ipsen's drugs Diphereline® 3.75mg & 11.25mg, Somatuline® Autogel® and Increlex® in selected countries in South-East Asia.

Transgenic mouse model study confirms passage of maternal thyroid hormones to fetus

Until now there were only indirect evidence of the transfer of thyroid hormones from mother to fetus through the placenta during pregnancy. That event is very important because the maternal thyroid hormones appear to play a key role in the development of the nervous system and other organs of the fetus; so it's true that in case of maternal thyroid disease, such hypothyroidism, have a direct bearing on the unborn child with reduction, also significant, to its Q.I..

Hormones leptin and insulin work together to affect regulation of blood sugar levels, female fertility

New findings by UT Southwestern Medical Center researchers suggest that the hormones leptin and insulin work together in specific neurons in the hypothalamus region of the brain to affect both the regulation of blood sugar levels in the body and, surprisingly, female fertility.
