Topical use of estradiol may stimulate collagen production in aging skin

Applying the hormone estradiol to skin protected from the sun appears to stimulate production of the protein collagen in older men and women, according to a report in the September issue of Archives of Dermatology, one of the JAMA/Archives journals. However, it may not have the same effect on sun-exposed skin, such as the face or arms.

Health scores after 1 year may predict survival in head and neck cancer patients

Changes in patients' physical health status during the year after being diagnosed with head and neck cancer appear to predict survival at five years, according to a report in the September issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

Sun-damaged skin does not improve with estrogen treatments

ANN ARBOR, Mich. — Treating the skin with estrogen can stimulate collagen production—which improves the appearance of the skin—in areas not typically exposed to the sun, according to new research from the University of Michigan Health System.

But in sun-damaged skin, the same treatment does not increase collagen production, the study found. The findings elucidate why it is so difficult to reverse the effects of sun damage on the skin, says lead author Laure Rittie, Ph.D., research investigator in the U-M Department of Dermatology.

Context is everything: An Armani ad on 1 page changes perception of Honda ad on next page

A person flipping through a magazine or watching TV sees a number of advertisements. Does the placement of those ads matter to consumers? A new study in the Journal of Consumer Research says it does. But whether people have a positive or negative impression depends on how knowledgeable they are about the products being pitched.

Herpes drug inhibits HIV in patients infected with both viruses

Researchers at the U.S. National Institutes of Health (NIH), McGill University and other institutions have discovered how a simple antiviral drug developed decades ago suppresses HIV in patients who are also infected with herpes. Their study was published in the Sept. 11 issue of the journal Cell Host and Microbe.

Don't throw the candy out: Temptation leads to moderation

Banishing tempting goodies may not be the best way to keep from eating them.

Tempting foods can actually increase willpower, according to new research in the Journal of Consumer Research. Although it seems counterintuitive, consumers show more self-control after they've spent some time in the presence of a treat.

Key protein molecule linked to diverse human chronic inflammatory diseases

Blacksburg, Va. -- Liwu Li, associate professor of biological sciences at Virginia Tech, has revealed a common connection between the cellular innate immunity network and human chronic inflammatory diseases, including atherosclerosis, Type 2 Diabetes, and neurodegenerative diseases. The finding presents a viable cellular and molecular target for the diagnosis and treatment of serious human inflammatory diseases, according to Li.

Help for shopaholics: New test determines who's at risk for compulsive buying

Shopaholics are the butt of many jokes, but obsessive or compulsive shopping can ruin lives.

Compulsive shopping can lead to financial problems, family conflicts, stress, depression, and loss of self-esteem. According to a new study in the Journal of Consumer Research, there may be more people engaged in compulsive buying than previously thought.

Pictures of hot fudge sundaes arouse: Understanding emotions improves our food choices

Menus and advertising affect our emotions, and if we understand those emotions, we make better food choices, according to a new study in the Journal of Consumer Research.

Authors Blair Kidwell, David M. Hardesty, and Terry L. Childers (all University of Kentucky) examined the "emotional intelligence" of consumers, including obese people. They found that people who made the healthiest choices had high correlations between their emotional intelligence and confidence in their emotional intelligence—what the authors call "emotional calibration."

Seize the day! New research helps tightwads 'live a little'

Some people have trouble indulging, and they regret it later. There's hope for those people, according to a new study in the Journal of Consumer Research.

Nanomedical approach targets multiple cancer genes, shrinks tumors more effectively

Nanoparticles filled with a drug that targets two genes that trigger melanoma could offer a potential cure for this deadly disease, according to cancer researchers. The treatment, administered through an ultrasound device, demonstrates a safer and more effective way of targeting cancer-causing genes in cancer cells without harming normal tissue.

Children's Hospital researchers identify genetic mutation that may predict organ rejection

Using a novel combination of cutting-edge technologies to scan the human genome, researchers at Children's Hospital of Pittsburgh of UPMC have identified a genetic mutation that identifies transplant recipients who experience rejection.

Genetic profile reveals susceptibility to cleft palate

PITTSBURGH, Sept. 15 – For the first time, researchers from the University of Pittsburgh School of Dental Medicine have identified a series of genetic mutations that appear to be linked to significant risk for cleft palate and other dental abnormalities. These are devastating conditions that cause tremendous social isolation, and also are associated with decreased lifespan, a higher risk of cancer and increased susceptibility to psychiatric disorders, even after surgical repair.

New data on melanoma treatment

People who carry a particular genetic variant are at significantly increased risk of developing malignant melanoma, new research shows.

Melanomas are known to be caused by exposure to the ultraviolet light in sunlight, but the precise mechanisms involved are complex. In a presentation at the 33rd Congress of the European Society for Medical Oncology (ESMO) in Stockholm, Portuguese researchers show that variations in a gene known as cyclin D1 also increase susceptibility to the disease.

Embryonic stem cells might help reduce transplantation rejection

Researchers have shown that immune-defense cells influenced by embryonic stem cell-derived cells can help prevent the rejection of hearts transplanted into mice, all without the use of immunosuppressive drugs.
