The Hypothalamus is the area of the brain that controls body temperature, hunger, and thirst.

Brain reacts differently to fructose compared with another common sweetener, glucose

The dietary concerns of too much fructose is well documented. High-fructose corn syrup has become the sweetener most commonly added to processed foods. Many dietary experts believe this increase directly correlates to the nation's growing obesity epidemic. Now, new research at Oregon Health & Science University demonstrates that the brain - which serves as a master control for body weight - reacts differently to fructose compared with another common sweetener, glucose.

Arena reduces workforce by 25% and provides update on lorcaserin

Arena Pharmaceuticals, Inc. announced today a reduction of its US workforce of approximately 25%, or 66 employees. As a result of the workforce reduction, which Arena plans to complete around March 28, 2011, the company expects to incur restructuring charges, primarily in the first quarter of 2011, of approximately $3.8 million in connection with one-time employee termination costs.

New molecular player responsible for regulation of appetite and metabolism

A study by researchers at Mayo Clinic's campus in Florida and Washington University School of Medicine adds a new twist to the body of evidence suggesting human obesity is due in part to genetic factors. While studying hormone receptors in laboratory mice, neuroscientists identified a new molecular player responsible for the regulation of appetite and metabolism.

First three-dimensional projectome map of intact brain

It would be hard to understand how a city is organized without knowledge of the course of all of its streets. Scientists confront the same problem when trying to understand the functioning of the brain. In the case of vertebrates, we only have fragmentary knowledge of which nerve cells send their connections, so-called axons, into certain regions of the brain.

Vasopressin in the brain maintains size of vasopressin neurons even when body fluid becomes more diluted

The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis.

New mouse model with deficiency of lipoprotein lipase in neurons

Researchers at the University of Colorado School of Medicine have created a new and exciting mouse model to study how lipid sensing and metabolism in the brain relate to the regulation of energy balance and body weight. The research team, led by Hong Wang, PhD, created mice with a deficiency of lipoprotein lipase (LPL) in neurons, and observed two important reactions.

Scientists pinpoint brain site where leptin hormone may trigger onset of puberty

UT Southwestern Medical Center researchers have pinpointed a tiny site in the brain where the hormone leptin may help trigger the onset of puberty.

Later onset of puberty associated with malnutrition, earlier onset to childhood obesity

The timing of the onset of puberty is linked to levels of nutrition: later onset is associated with malnutrition, while earlier onset is linked to childhood obesity. A team of researchers, led by Carol Elias, at the University of Texas Southwestern Medical Center, Dallas, has now generated data in mice that run counter to current thinking about the molecular pathway by which nutrition status affects the onset of puberty. Further, the team defines a new regulatory pathway for the process, which, if confirmed in humans, could potentially lead to new approaches to treating disorders of puberty and fertility.

Gene mutation can lead to different mental illnesses when influenced by same environmental factor

Male mice born with a genetic mutation that's believed to make humans more susceptible to schizophrenia develop behaviors that mimic other major psychiatric illnesses when their mothers are exposed to an assault to the immune system while pregnant, according to new Johns Hopkins research.

Diabetes plays a vital role in regulating brain cholesterol: Research

The brain contains more cholesterol than any other organ in the body, has to produce its own cholesterol and won't function normally if it doesn't churn out enough. Defects in cholesterol metabolism have been linked with Alzheimer's disease and other neurodegenerative conditions. Now researchers at Joslin Diabetes Center have discovered that diabetes can affect how much cholesterol the brain can make.

Santarus announces commercial U.S. launch of CYCLOSET for type 2 diabetes mellitus

Santarus, Inc., a specialty biopharmaceutical company, today announced the commercial U.S. launch of CYCLOSET (bromocriptine mesylate) tablets. CYCLOSET is a prescription drug approved by the U.S. Food and Drug Administration (FDA) as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus both as monotherapy and in combination with other oral antidiabetic agents.

Arena and Eisai report positive results from lorcaserin BLOOM-DM trial in obese, overweight diabetics

Arena Pharmaceuticals, Inc. and Eisai Inc. reported today that top-line results from the one-year lorcaserin BLOOM-DM trial demonstrate statistically significant weight loss in obese and overweight patients with type 2 diabetes. In this trial, lorcaserin met all three co-primary efficacy endpoints. In addition, as described below, lorcaserin patients taking lorcaserin 10 mg twice daily (BID) achieved statistically significant improvements in multiple secondary endpoints, including HbA1c, as compared to patients randomized to placebo.

Study finds anti-obesity drug reduces brain’s response to appetizing foods

Scientists have revealed that an anti-obesity drug changes the way the brain responds to appetising, high-calorie foods in obese individuals. This insight may aid the development of new anti-obesity drugs which reduce the activity in the regions of the brain stimulated by the sight of tasty foods.

Colour of light influences the way brain processes emotional stimuli

Researchers at the Cyclotron Research Centre (University of Liege), Geneva Center for Neuroscience and Swiss Center for Affective Sciences (University of Geneva), and Surrey Sleep Research Centre (University of Surrey) investigated the immediate effect of light, and of its color composition, on emotion brain processing using functional magnetic resonance imaging. The results of their study show that the colour of light influences the way the brain processes emotional stimuli.

Scientists find two proteins that regulates water retention in salt-sensitive hypertension

Research conducted by scientists at LSU Health Sciences Center New Orleans has found that two proteins in the brain act as valves to turn the hormone that regulates water retention in the body on and off. Their findings may lead to advances in treatment for diseases like high blood pressure, congestive heart failure, and cirrhosis of the liver. The research is published in the November 1, 2010 issue of Endocrinology.
