GENDER LINKED TO DEVELOPMENT OF SKIN CANCER

Inherent gender differences -- instead of more sun exposure -- may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center.

INTERNATIONAL STUDY FINDS WAYS TO MAXIMIZE EFFECTIVE RESPONSES AFTER TERRORISM INCIDENTS

A new international study led by faculty at the Medical College of Wisconsin in Milwaukee, has identified ways to maximize the effectiveness of responses to terrorist attacks that use explosive devices on civilian populations. The study, "Blast Related Injuries from Terrorism: an International Perspective," will be published in the April 1, 2007, issue of Prehospital Emergency Care (volume 11 issue 2).

ACTIGRAPHY IS A USEFUL WAY TO ASSESS AND MANAGE SLEEP DISORDERS

Actigraphy, the use of a portable device that records movement over extended periods of time, and has been used extensively in the study of sleep and circadian rhythms, provides an acceptably accurate estimate of sleep patterns in normal, healthy adult populations and in-patients suspected of certain sleep disorders.

NEW STUDY IN SLEEP FINDS THAT SLEEP DISTURBANCE INCREASES SPONTANEOUS PAIN IN WOMEN

Sleep continuity disturbance impairs endogenous pain-inhibitory function and increases spontaneous pain in women. This supports a possible pathophysiologic role of sleep disturbance in chronic pain.

SLEEP QUANTITY AFFECTS MORNING TESTOSTERONE LEVELS IN OLDER MEN

The testosterone levels of healthy men decline as they get older. As sleep quality and quantity typically decrease with age, objectively measured differences in the amount of sleep a healthy older man gets can affect his level of testosterone in the morning.

GETTING DIRTY MAY LIFT YOUR MOOD

Treatment of mice with a "friendly" bacteria, normally found in the soil, altered their behavior in a way similar to that produced by antidepressant drugs, reports research published in the latest issue of Neuroscience. These findings, identified by researchers at the University of Bristol and colleagues at University College London, aid the understanding of why an imbalance in the immune system leaves some individuals vulnerable to mood disorders like depression.

IT’S NEVER TOO LATE TO GET IT BACK! AGING INTERRUPTED

Scientists have discovered that reducing calorie intake later in life can still induce many of the health and longevity benefits of life-long calorie reduction. Importantly, this also includes anti-cancer effects. They are using this knowledge to establish a novel screening technique to find drugs which mimic this longevity effect.

FAT OVERRIDES EFFECTS OF VITAMIN C

Fats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential cancer-forming compounds in the stomach is less than when no lipids are present.

RIGHT ANGLES ARE ALL WRONG FOR TREE FROG ADHESION

Tree frogs have the unique ability to stick to smooth surfaces even when they are tilted well beyond the vertical -- some small tree frogs can even adhere when completely upside down. Conversely when walking or jumping they can detach their toe pads easily. Researchers from the University of Glasgow will present insights into how this fascinating ability is controlled.

STUDY IDENTIFIES MULTIPLE GENETIC RISK FACTORS FOR PROSTATE CANCER

A study led by researchers at the Keck School of Medicine of the University of Southern California and Harvard Medical School has identified seven genetic risk factors that predict risk for prostate cancer. According to the study's findings, these risk factors are clustered in a single region of the human genome on chromosome 8 and powerfully predict a man's probability of developing prostate cancer.
