(Ivanhoe Newswire) "“ A drug that regulates your body clock may also be able to treat depression. A new study found that patients who take agomelatine have improved moods, sleep better and experience fewer side effects than those on traditional anti-depressants. Most anti-depressants work by raising the levels of a chemical in the brain called serotonin, which affects mood. However the medications can lead to sickness and loss of sex drive. Scientists think agomelatine works well...

The judgments we make about the intimacy of other couples' relationships appear to be influenced by the brain chemical serotonin, reports a new study published in Biological Psychiatry. Healthy adult volunteers, whose levels of serotonin activity had been lowered, rated couples in photos as being less intimate and less romantic than volunteers with normal serotonin activity. The approach involved giving amino acid drinks to two groups of volunteers in order to manipulate blood concentrations...

Baylor College of Medicine is recruiting boys between the ages of 4 and 9 years for a study on sleep patterns and melatonin in children with and without autism. Volunteers will be asked to wear an actigraph, similar to a wristwatch, for one week to measure their activity. An overnight stay at Texas Children's Hospital also will be required. Volunteers will be compensated for their time. For more information, contact Aryn Knight at 832-822-3751 or apolk@bcm.edu. --- On the Net: BCM

Chinese scientists say they have found a chemical inside the brains of mice that controls sexual preference. The researchers, reporting their findings in the journal Nature, said male mice bred without serotonin lose their preference for females. They said it is the first time that a neurotransmitter has been shown to play a role in sexual preference in mammals. The team first bred male mice whose brains were not receptive to serotonin. Experiments showed that these mice had lost preference...

Rise in substance's level in the brain improved social behaviors in mice Mouse models are yielding important clues about the nature of autism spectrum disorders, which impact an estimated one in 110 children in the U.S. In labs at the UT Health Science Center San Antonio, researchers are studying strains of mice that inherently mimic the repetitive and socially impaired behaviors present in these disorders.

Changes in diet have been linked to a reduction of abnormal behaviors in mentally ill people or animals, but a Purdue University study shows that diet might also trigger the onset of mental illness in the first place. Joseph Garner, an associate professor of animal sciences, fed mice a diet high in sugar and tryptophan that was expected to reduce abnormal hair-pulling. Instead, mice that were already ill worsened their hair-pulling behaviors or started a new self-injurious scratching...

(Ivanhoe Newswire) -- Kidney disease patients benefit long-term from a produce-rich diet, including fruits and vegetables.  They also get a short-term boost from melatonin. Patients with kidney disease don't benefit from the stereotypical Western diet which produces and acidic environment in the body. Nimirit Goraya, MD (Texas A&M College of Medicine and Scott and White Healthcare) and her colleagues conducted a study to see if consuming a diet high in fruits and vegetables that...

Exposure to even dim light at night is enough to cause physical changes in the brains of hamsters that may be associated with depression, a new study shows. Researchers found that female Siberian hamsters exposed to dim light every night for eight weeks showed significant changes in a part of the brain called the hippocampus. This is the first time researchers have found that light at night, by itself, may be linked to changes in the hippocampus. These alterations may be a key reason why the...

MUNICH, Germany, September 7, 2010 /PRNewswire/ -- After more than five years of intensive research a Munich-based company has managed to produce milk with a high level of melatonin. Special food is given to the cows and they are milked at night. Milk crystals - so called Nacht-Milchkristalle - are produced from the night-time milk. They contain 100 times more melatonin than normal milk and can be offered as food in Europe without a prescription. Melatonin is considered one of the...

A new study from the Center for Interdisciplinary Chronobiological Research at the University of Haifa has found an additional link between Light At Night (LAN) and cancer. This research joins a series of earlier studies carried out at the University of Haifa that also established the correlation. "High power light bulbs contribute more to "Ëœenvironmental light pollution', which the study has shown is a carcinogenic pollution," notes Prof. Abraham Haim, who headed the study....
