Scientists discover a catalytic antibody that degrades a known appetite stimulant

The antibody works against the gastric hormone ghrelin (pronounced "grell-in"), which has been linked to weight gain and fat storage through its metabolic actions. These findings point towards a potentially novel treatment for obesity that would interfere directly with the some of the biological mechanisms determining weight.

High-dose hormone treatment might reduce risk for posttraumatic stress disorder

Cortisol helps our bodies cope with stress, but what about its effects on the brain? A new study by Cohen and colleagues, appearing in the October 15th issue of Biological Psychiatry, suggests that the answer to this question is complex.

Genes that control cell death may play role in age-related hearing loss

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to research published online in the journal Apoptosis - a journal devoted to the topic of cell suicide, or programmed cell death.

New therapy for heart failure

During heart failure the body reacts to the production of the hormone aldosterone. Too much aldosterone can stiffen and damage the muscles of the heart.

People with severe obstructive sleep apnea often have poor diets

A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that unrelated to obesity, people with severe SDBs consume a more unhealthy diet, which may be a factor contributing to greater cardiovascular morbidity and mortality. These findings were most evident among women.

Respiratory sinus arrhythmia is a significant predictor of insomnia in women with breast cancer

A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that respiratory sinus arrhythmia (RSA) is a significant predictor of insomnia in women with breast cancer and confirmed that longer nocturnal wake episodes were associated with a flatter diurnal cortisol slope.

Resveratrol shows promise for treating human alcoholic fatty liver disease

The accumulation of fat in the liver as a result of chronic alcohol consumption could be prevented by consuming resveratrol, according to a new study with mice. The research found that resveratrol reduced the amount of fat produced in the liver of mice fed alcohol and, at the same time, increased the rate at which fat within the liver is broken down.

Caffeine not associated with overall breast cancer risk

Caffeine consumption does not appear to be associated with overall breast cancer risk, according to a report in the October 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. However, there is a possibility of increased risk for women with benign breast disease or for tumors that are hormone-receptor negative or larger than 2 centimeters.
