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 
Study identifies genes that protect against aging

Scientists at the University of Liverpool have developed a new method to help researchers identify genes that can help protect the body during the aging process.
The team developed a method of analyzing genes in several types of aging tissue in both animals and humans. The analysis, which included more than five million gene measurements, highlighted the mechanisms used by the body to protect against age-related cellular changes that can result in muscle degeneration and cognitive aging
Aspirin and Similar Drugs May Be Associated with Brain Microbleeds in Older Adults

Individuals who take aspirin or other medications that prevent blood clotting by inhibiting the accumulation of platelets appear more likely to have tiny, asymptomatic areas of bleeding in the brain, according to a report posted online today that will appear in the June print issue of Archives of Neurology, one of the JAMA/Archives journals.
Vitamin D Supplements Associated with Reduced Fracture Risk in Older Adults

Oral vitamin D supplements at a dose of at least 400 international units per day are associated with a reduced risk of bone fractures in older adults, according to results of a meta-analysis.
Ticking of body's 24-hour clock turns gears of metabolism and aging
piggy submitted, created time 1 year 5 months (www.eurekalert.org)
All animals, including humans, have an internal 24-hour clock or circadian rhythm that creates a daily oscillation of body temperature, brain activity, hormone production and metabolism. Studying mice, researchers at Washington University School of Medicine in St. Louis and Northwestern University found how the biological circadian clock mechanism communicates with processes that govern aging and metabolism
Not so sweet: Over-consumption of sugar linked to aging
piggy submitted, created time 1 year 6 months (www.eurekalert.org)
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
Vigorous Exercise May Help Prevent Vision Loss

There’s another reason to dust off those running shoes. Vigorous exercise may help prevent vision loss, according to a pair of studies from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. The studies tracked approximately 41,000 runners for more than seven years, and found that running reduced the risk of both cataracts and age-related macular degeneration.
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
Visual Decline As We Age: Genetics or Environment?

Which has a larger impact on the "normal" decline of visual function as we age, genetic or environmental factors? This question is explored in the February issue of Ophthalmology, the journal of the American Academy of Ophthalmology.
The study was performed on forty-two sets of twins, twenty-one identical and twenty-one fraternal. There was a strong genetic correlation with functions involving sharp and color vision--things concerning cone cells, but not with night vision or light detection--things concerning rod cells.
Apple Juice Can Delay Onset of Alzheimer's Disease, Study Suggests

A growing body of evidence demonstrates that we can take steps to delay age-related cognitive decline, including in some cases that which accompanies Alzheimer's disease, according to a study published in the Journal of Alzheimer's Disease.

Feeling Old? Blame Your Nuclear Pores
piggy submitted, created time 1 year 7 months (sciencenow.sciencemag.org)
As if gimpy knees, clogged arteries, and forgetfulness weren't bad enough, new research has identified another way our bodies falter as we get older. The pores that permit only certain molecules to enter and exit the nuclei of our cells start leaking. A new study raises the possibility that permissive pores trigger some of the physical decline of old age.
Nuclear pores aren't mere portholes. Each consists of about thirty different proteins called nucleoporins that control what goes in and out of the nucleus

Brown University researchers have identified a cellular mechanism that could someday help fight the aging process.
New Tests Needed to Predict Cardiovascular Problems in Older People More Accurately

A long-standing system for assessing the risk of cardiovascular disease amongst older people should be replaced with something more accurate, according to a study published published on the British Medical Journal website.
Sirtuin shown to control gene activity

A formerly underappreciated member of the sirtuin family of proteins may hold the key to youthfulness. It is the first sirtuin shown to specifically govern the activity of genes.
Old gastrointestinal drug slows neurodegenerative diseases
sea-maid submitted, created time 1 year 7 months (www.eurekalert.org)
Recent animal studies have shown that clioquinol – an eighty-year-old drug once used to treat diarrhea and other gastrointestinal disorders – can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases. Scientists, however, had a variety of theories to attempt to explain how a single compound could have such similar effects on three unrelated neurodegenerative disorders.
Researchers at McGill University have discovered a dramatic possible new answer: According to Dr
