Study leader Kathleen Sluka, PhD., found a protein included in muscle pain works in conjunction with the male hormone testosterone to protect against muscle fatigue

A recent study revealed that children who lead sedentary lives were six times more likely to develop heart complications when they enter their teenage years.

Researchers from the University of North Carolina derived their findings from an experiment involving almost 400 children aged between seven and 10. Led by Robert McMurray, the experts analyzed each child's overall physical condition, taking into consideration the body mass index, body fat percentage, height, blood pressure, and cholesterol levels

early 30 surveys by France's INSERM, a public organization dedicated to biological, medical and public health research, have established a link between lack of sleep and obesity in both children and adults.

Sleep loss caused a 23 to 24 percent increase in hunger, translating into an extra 350 to 500 kilocalories a day, "which for a young sedentary adult of normal weight could lead to a major amount of added weight," Spiegel said according to Agency France Presse

Home defibrillators do not boost the chances of surviving a heart attack, according to research published Tuesday.

The study, involving 7,001 people, was led by Dr. Gust Bardy of the Seattle Institute of Cardiac Research

The U.S. Food and Drug Administration (FDA) is working with the drug company Merck to investigate a possible link between Merck's asthma and allergy drug Singulair and suicide risk associated with it. Meanwhile, "patients should not stop taking Singulair before talking to their doctor," the FDA said in a statement, adding that doctors should monitor patients for suicidal behavior and mood changes.

The federal agency said that the investigation may take nine months. Currently there is no proof that Singulair can lead to mood changes, suicidal behavior and suicide in patients
