NEW YORK (Reuters Health) - A nasal spray containing the hormone oxytocin, which is essential to the production and flow of breast milk, does not improve milk output in mothers expressing milk for preterm infants, a study shows. "Mothers may experience difficulties in expressing breast milk for infants too immature or sick to breast feed," Dr. M.S. Fewtrell, of the Institute of Child Health in London, and colleagues explain. "Oxytocin has been used to assist breast feeding and milk...
Discovery could lead to new treatments, researchers sayExperiments in rats have linked the craving for cocaine to a specific molecule that appears to train the brain to crave the drug.The finding could lead to addiction treatments that would block this biologic trigger, experts say.The researchers found that a protein, called orexin A, acts on an area of the brain that is key to priming the brain for addictive drugs. In experiments with rats, they show that orexin A causes an adaptation that...
LONDON (Reuters) - Forget pretending you are talking to one person or concentrating on a single point in the audience -- having sex is good way to calm nerves before giving a speech or presentation.But Stuart Brody, a psychologist at the University of Paisley in Scotland, said it has to be full sexual intercourse to get the best results.He studied nearly 50 men and women who recorded their sexual activities for two weeks and analyzed its impact on their blood pressure levels when under acute...

A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry, a brain imaging study at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has discovered. Scans of the hormone oxytocin's effect on human brain function reveal that it quells the brain's fear hub, the amygdala, and its brainstem relay stations in response to fearful stimuli. The work at NIMH and a collaborating site in...
By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Daily hormone injections helped dieters keep weight off in a study that helped shed light on why it is so easy to gain weight and so hard to keep it off, researchers said on Thursday. Their study showed that the hormone leptin, useless for helping people lose weight, could help people maintain weight loss -- as long as they got twice-daily injections. The finding helps researchers understand the complex way that...
By Deborah Zabarenko WASHINGTON (Reuters) - Doses of a newly discovered hormone made laboratory animals eat half what they normally would, and cut their body weight by 20 percent in just eight days, scientists reported on Thursday in the journal Science. Whether the hormone will have similar effects on humans remains to be seen. It is also unclear whether the weight loss in lab rodents represents a decrease in fat mass, which would be desirable, or muscle mass, which would not be. But...
NEW YORK (Reuters Health) - Researchers from Stanford University School of Medicine in California have discovered a hormone, which they dubbed obestatin, that suppresses appetite and produces weight loss in rats. Interestingly, the hormone is derived from the same gene that gives rise to ghrelin, a well-known appetite-inducing hormone. Ghrelin is derived from a precursor or "pro-hormone" called proghrelin, according to the report in the research journal Science. However, research...
"Take two cheeseburgers and call me in the morning," may sound like far-fetched medical advice. After all, high fat foods can worsen blockages in blood vessels. But a new study in the October 17 issue of The Journal of Experimental Medicine shows that high fat foods can, at least in the gut, soothe inflammation. This action may stop immune cells from attacking food as a foreign invader. Eating -- particularly eating fat-rich foods -- causes cells in the small intestine to produce a...
(Philadelphia, PA) "“ Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain. By identifying the relationship between orexin neurons and behaviors associated with reward seeking, drug relapse, and addiction, researchers hope to find new treatments for drug addiction. Previous studies have...

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...
