Using a topical application of the antioxidant ellagic acid, researchers at Hallym University in the Republic of Korea markedly prevented collagen destruction and inflammatory response – major causes of wrinkles -- in both human skin cells and the sensitive skin of hairless mice following continuing exposure to UV-B, the sun's skin-damaging ultraviolet radioactive rays.
Ji-Young Bae, a graduate student in the laboratory of Dr. Young-Hee Kang, presented results of the two-part study on Tuesday, April 21, at the Experimental Biology 2009 meeting in New Orleans 
Source of Olive Oil's Major Health Benefits Revealed

Scientists have pinned down the constituent of olive oil that gives greatest protection from heart attack and stroke. In a study of the major antioxidants in olive oil, Portuguese researchers showed that one, DHPEA-EDA, protects red blood cells from damage more than any other part of olive oil.
"These findings provide the scientific basis for the clear health benefits that have been seen in people who have olive oil in their diet," says lead researcher Fatima Paiva-Martins, who works at the University of Porto

Drinking hot tea may cause throat cancer, Iranian researchers said Friday, suggesting people should let steaming drinks cool before consuming them.
Licorice may interfere with certain drugs

Studies in rats suggest that licorice may block the effectiveness of some drugs, including cyclosporin, a drug widely used by transplant patients.
Eating Red and Processed Meat Associated with Increased Risk of Death

Individuals who eat more red meat and processed meat appear to have a modestly increased risk of death from all causes and also from cancer or heart disease over a ten-year period, according to a new article. In contrast, a higher intake of white meat appeared to be associated with a slightly decreased risk for overall death and cancer death.
Advice to Vultures: Avoid Spanish Livestock

Eating carcasses of livestock treated with antibiotics is wreaking havoc on the health of Spanish vultures, a new study carried out in Spain suggests. The researchers say that the practice of feeding vultures livestock carrion--although promoted by bird lovers--may actually threaten the species and should be ended.
Data collected from seventy-one nestlings from carrion-dependent areas suggest that the antibiotics used in meat production both collect in the vultures' bodies and inhibit their immune systems
Men control appetite better than women

Men have a better ability to suppress their hunger than women when presented with food.
Male and female study participants fasted for eighteen hours, and then got to see and smell their favorite foods. For the following thirty minutes, participants filled out surveys about their feelings of hunger and, while linked up to brain imaging equipment, attempted to stop thinking about food.
Men showed less hunger-related brain activity than women did. Researchers suspect that the female sex hormones, already linked to weight gain, may have something to do with this.
Drugs from Vegetables May Target Melanoma Tumors

A drug based on isothiocyanates extracted from cruciferous vegetables such as broccoli and cabbage could offer a potent and safe treatment against melanoma, Penn State College of Medicine researchers say.
Recent mouse model experiments found that treatments involving both isothiocyanates and selenium reduced tumor growth by about sixty percent by interfering with a protein called Akt3.
The specific drug used in these tests was not an isothiocyanate, but a construct called isoselenocyanate
Not so sweet: Over-consumption of sugar linked to aging

We know that lifespan can be extended in animals by restricting calories such as those gleaned from sugar intake. Now, according to a study published in the journal PLoS Genetics, Université de Montréal scientists have discovered that it's not the sugar itself that is important in this process but the ability of cells to sense its presence.
Aging is a complex phenomenon and the mechanisms underlying it have yet to be explained. What researchers do know is that there is a clear relationship between aging and calorie intake
Obesity Gene Involved in Weight Gain Response to High-Fat Diet Identified

Scientists have determined that a specific gene plays a role in the weight-gain response to a high-fat diet.
The finding in an animal study suggests that blocking this gene could one day be a therapeutic strategy to reduce diet-related obesity and associated disorders, such as diabetes and liver damage, in humans.
The researchers found that a diet rich in fat induced production of this gene, called protein kinase C beta (PKC beta), in the fat cells of mice. These mice rapidly gained weight while eating a high-fat diet for twelve weeks.
Gene to reduce wheat yield losses

A new gene that provides resistance to a fungal disease responsible for millions of hectares of lost wheat yield has been discovered by scientists from the U.S. and Israel.
"This is the first step to achieving more durable resistance to a devastating disease in wheat," said Dr Cristobal Uauy, co-author of the report, recently appointed to the John Innes Centre in Norwich.
Resistance to stripe rust has previously been achieved using genes that are specific to single races of the disease
Trial Offers Hope for Curing Peanut Allergies

A team of British scientists on Friday said it had come one step closer to curing nut allergies following a small-scale clinical trial in which they successfully built up children's tolerance to peanuts.
Food Counterfeiting, Contamination Outpace International Regulatory Systems

Intentionally contaminated Chinese milk killed several children and sickened 300,000 more, causing concern around an increasingly connected world economy. Demand for inexpensive products virtually guarantees future repeats of food adulteration and counterfeiting from overseas, Michigan State University researchers said, as trade volumes overwhelm regulatory oversight.
New lab evidence suggests preventive effects of herbal supplement in prostate cancer
piggy submitted, created time 1 year 6 months (www.eurekalert.org)
DHEA is a natural circulating hormone and the body's production of it decreases with age. Men take DHEA as an over-the-counter supplement because it has been suggested that DHEA can reverse aging or have anabolic effects since it can be metabolized in the body to androgens. Increased consumption of dietary isoflavones is associated with a decreased risk of prostate cancer. Red clover (Trifolium pretense) is one source of isoflavones. Both supplements may have hormonal effects in the prostate and little is known about the safety of these supplements
Novel Benefits of Fatty Acids in Arteries Shown

New research from Columbia University Medical Center continues to shed light on the benefits of making fish a staple of any diet. It seems that a diet rich in fish-provided omega-3 fatty acids can prevent buildup of fat in the aorta.
