Lack of sleep is a common complaint but for many, falling asleep involuntarily during the day poses a very real and dangerous problem. A new study from the Montreal Neurological Institute (MNI) at McGill University demonstrates interestingly, that sleep-wake states are regulated by two different types of nerve cells (neurons), melanin-concentrating hormone (MCH) neurons and orexin (Orx) neurons, which occupy the same region of the brain but perform opposite functions. The MNI study is the...

Mice with increased levels of a natural brain chemical don't gain weight when fed a high-fat diet, researchers at UT Southwestern Medical Center have found. The chemical, orexin, works by increasing the body's sensitivity to the "weight-loss hormone," leptin, the researchers report. Finding a way to boost the orexin system may prove useful as a therapy against obesity, said Dr. Masashi Yanagisawa, professor of molecular genetics at UT Southwestern and senior author of the study, which appears...

Mothers who breastfeed are less likely to neglect their children, said a Baylor College of Medicine researcher in a report that appears online in the journal Pediatrics today. Although many factors are associated with maternal neglect, this study provides new evidence that breastfeeding may have a protective effect, said Dr. Lane Strathearn, assistant professor of pediatrics at BCM and Texas Children's Hospital and the senior author on the study.Strengthening bond "Promoting breastfeeding may...

University of Wisconsin-Madison researchers have solved the mystery surrounding a "rogue protein" that plays a role in the release of neurotransmitters and hormones in the brain. The scientists found abundant amounts of the puzzling protein "” whose main location and function were unknown until now "” in a specific area of the pituitary gland. Like someone at a control knob, the protein may adjust the release of the two hormones that come almost exclusively from the posterior...

People with autism or other conditions that impact social skills might benefit from new research on hormones.  Scientists say the hormone oxytocin can boost the ability of humans to recognize faces.Swiss and U.S. researchers decided to study oxytocin because the hormone, which is known to play a role in childbirth and breastfeeding, has been shown to influence social recognition in mice. In this study, they administered a single dose of either oxytocin or a placebo to study participants...

Having trouble with your marriage? Take a pill!  Believe it or not, this could happen, says the researcher who is examining the chemical composition of love.Larry Young states that his ultimate goal is not a love potion but hopes to find information on conditions like autism, which limits the natural ability to create social attachments, by investigating brain chemicals connected to emotional attachment."Biologists may soon be able to reduce certain mental states associated with love to...

The potential of the appetite suppressing hormone -- leptin -- may be realized after all, U.S. researchers say. The discovery of leptin, an appetite-suppressing hormone secreted by fat tissue, created great hopes for an effective treatment for obesity, but it was found the obese are unresponsive to leptin due to leptin resistance in the brain. The study, published in Cell Metabolism, found two chaperones -- 4-PBA or TUDCA -- increase leptin sensitivity as much as 10-fold and resulted in...

Swiss researchers said on Tuesday, that the "love" hormone linked to feelings of sexual pleasure, bonding and maternal care also appears to help us recognize familiar faces. Peter Klaver of the University of Zurich and colleagues reported that men given oxytocin more accurately recalled images of familiar faces but the hormone did not help them recognize inanimate objects. Researchers said the hormone somehow strengthens the brain's neural networks involved in social memory and may have...

Researchers from Duke University Medical Center have identified a variation in a particular gene that increases susceptibility to early coronary artery disease. For years, scientists have known that the devastating, early-onset form of the disease was inherited, but they knew little about the gene(s) responsible until now. The results are published January 2 in the open-access journal PLoS Genetics. In a previous study, a region on chromosome 7 was linked to coronary artery disease (CAD)....

For those who want to lose weight, aerobic exercise is better at suppressing appetite than non-aerobic exercise, British researchers have found. David J. Stensel of Loughborough University in England and colleagues said a vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting only affects the level of ghrelin. The researchers said ghrelin is the only hormone known to stimulate appetite, while...

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...
