SAN DIEGO, March 24, 2010 /PRNewswire-FirstCall/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) announced today the initiation of patient screening in a Phase 1 clinical trial of APD916, a novel oral drug candidate discovered by Arena that targets the histamine H3 receptor for the treatment of narcolepsy and cataplexy. "There is a need for better tolerated, more effective therapies for narcolepsy, especially narcolepsy with cataplexy," said William R. Shanahan, M.D., Arena's Vice President...

Researchers at the California Institute of Technology (Caltech) and the University of California, San Diego (UCSD) have discovered that injecting a simple hormone into leeches creates a novel way to study how hormones and the nervous system work together to produce species-specific reproductive behavior. A paper describing the work appears in the March 11 online edition of the journal Current Biology. Daniel Wagenaar, Broad Senior Research Fellow in Brain Circuitry at Caltech and first author...

Scientists have pinpointed how a key hormone helps animals to recognize others by their smell Researchers at the University of Edinburgh have shown that the hormone vasopressin helps the brain differentiate between familiar and new scents. The study, published in the journal Nature, suggests that when the hormone fails to function, animals are unable to recognise other individuals from their scent. The ability to recognise others by smell is crucial in helping animals to establish strong...

The premise that hunger makes food look more appealing is a widely held belief "“ just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet. Prior research studies have suggested that the so-called hunger hormone ghrelin, which the body produces when it's hungry, might act on the brain to trigger this behavior. New research in mice by UT Southwestern Medical Center scientists suggest that ghrelin might also work in the...

The brain acts as a profound regulatory centre, controlling myriad processes throughout the body in ways we are only just beginning to understand. In new findings, Australian scientists have shown surprising connections between the brain and regulation of bone mass. One of the key functions of our skeletons is to provide mechanical support. In order to fulfil this role, bone tissue is modified throughout our lives, in response to changing activity levels and body weight. Bone mass increases...

Researchers at the University of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive. In contrast to "every man for himself" interpretations of Charles Darwin's theory of evolution by natural selection, Dacher Keltner, a UC Berkeley psychologist and author...

Even the anticipation of sweets may cause our muscles to start taking up more blood sugar, say researchers reporting in the December issue of Cell Metabolism, a Cell Press publication. That message is delivered via neurons in the brain's hypothalamus containing the chemical known as orexin and the sympathetic nervous system, the studies in mice and rats suggest. Orexin neurons are known to switch on when we are motivated to eat or seek other rewards. They also play a role in active...

Taste stimulation and its anticipation activates muscle glucose metabolism via 'orexin' neurons in the brain and thereby reduces blood glucose level in mice Japanese research group led by Professor Yasuhiko Minokoshi and Dr. Tetsuya Shiuchi, scientists at the National Institute for Physiological Sciences, NIPS, Japan, found that meals stimulated with sweet taste and motivated with its anticipation regularly activates "orexin" in the brain and it stimulates muscle glucose metabolism via the...

Ghrelin, a hormone produced in the stomach, may be used to boost resistance to, or slow, the development of Parkinson's disease, Yale School of Medicine researchers report in a study published in a recent issue of the Journal of Neuroscience. Parkinson's disease is caused by a degeneration of dopamine neurons in an area of the midbrain known as the substantia nigra, which is responsible for dopamine production. Reduced production of dopamine in late-stage Parkinson's causes symptoms such as...

Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin's receptor was linked to a person's ability to infer the mental state of others. Interestingly, this same genetic variation also related to stress reactivity. These findings could have a significant impact in adding to the body of knowledge about the importance of oxytocin,...

Labor Induction is a process of giving an artificial start to birth with medical intervention or other methods. When an induction is not performed for emergency or other medical reasons, the method is considered an elective process. The decision to induce labor has increased in recent years due to its convenience or because it easily accommodates busy schedules. The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...
