Looks, not health risk, motivate teens to wear sunscreen

After offering information about UV light and sun-protective behaviors, the two health-ed videos diverge: one describes the increased skin cancer risk of UV exposure and the other describes effects on appearance including wrinkles and premature aging. Which of these two videos do you think caused teenagers to use more sunscreen six weeks after it was shown?

Study shows vitamin D provides relief for those with chronic hives

A study by researchers at the University of Nebraska Medical Center shows vitamin D as an add-on therapy could provide some relief for chronic hives, a condition with no cure and few treatment options.An allergic skin condition, chronic hives create red, itchy welts on the skin and sometimes swelling. They can occur daily and last longer than six weeks, even years.Jill Poole, M.D.

Patients with body dysmorphic disorder benefit from cognitive behavioral therapy

In a recent study, researchers at Rhode Island Hospital found significant benefits of cognitive behavioral therapy as a treatment modality for patients with Body Dysmorphic Disorder (BDD). BDD is a common, often severe, and under-recognized body image disorder that affects an estimated 1.7 percent to 2.4 percent of the population.

Unique regulatory T cell population identified in human skin

Regulatory T cells (Tregs) dampen the immune response against self antigens and contribute to the prevention of autoimmunity. A skin-specific population of Tregs (mTreg) has been described in mice that has properties similar to memory T cells. In mice, some mTregs are maintained in the skin for long periods of time and suppress cutaneous autoimmunity.

Surprising link discovered between chloracne and a molecule that protects cells against stress

ETH-Zurich researchers have discovered a new, surprising link between chloracne and a molecule that protects cells against stress: if Nrf2 gets out of control, disfiguring cysts form on the skin.The images were seen all over the world and stuck in the minds of many: in the autumn of 2004, former President of the Ukraine, Viktor Yushchenko, was poisoned with a high dose of dioxin.

A metabolic molecule inhibits blood vessel growth in patients with diabetes, leading to impaired wound healing

Patients with diabetes are at increased risk of microvascular complications, which develop when the body's small blood vessels become diseased. One of the most common problems results when wounds fail to heal properly, which can lead to ulcers, chronic infections, and in the most serious cases, limb amputations.
