Penn researchers demonstrate that a metabolic enzyme works through the tumor-suppressor protein p53 to control cellular replication

Researchers at the University of Pennsylvania School of Medicine have identified in normal cells that a common metabolic enzyme, which acts as a rheostat of cellular conditions, also controls cell replication.

Alternate view for pathology of Alzheimer's disease

A new paper from researchers at the Case Western Reserve University School of Medicine challenges the classic theory that the nerve tangles seen in the brains of Alzheimer's disease (AD) victims are the cause of the disease, but rather proposes that they are a protective response to the disease. Their paper appears in the April issue of the journal Trends in Molecular Medicine.

Eat your fruits and veggies - your body will thank you and your mother will be happy!

Eat your fruits and veggies - your body will thank you and your mother will be happy! And if that's not reason enough, a new study suggests antioxidant-rich fruits and vegetables may limit brain damage from stroke and other neurological disorders.

Researchers have identified a new clinical syndrome

Researchers have identified a new clinical syndrome that produces serious and sometimes fatal symptoms in a variety of seemingly unrelated diseases. The syndrome, described in the April 6 issue of the Journal of the American Medical Association, is caused by hemolysis, the destruction of red blood cells.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Autistic children found to have abnormal metabolic profile

Autism, a neurodevelopment disorder which has increased tenfold over the last 15 years, now affects 30 of every 10,000 children in the United States.

Children with autism have a severely abnormal metabolic profile

Chronic biochemical imbalance is often a primary factor in the development of many complex diseases but a possible metabolic basis for autism has not been well explored. Now Arkansas Children's Hospital Research Institute researchers report for the first time that children with autism have a severely abnormal metabolic profile indicating increased vulnerability to oxidative stress.

Traffic fumes can damage our DNA

A research team in Taiwan studied the effects of exposure to traffic fumes at 20 toll booths located on a motorway 10 km south of Taipei, Taiwan, which has the highest traffic density of any toll station in the country.

Compound found in broccoli is a powerful disease fighter

More than 300 scientific studies point to an antioxidant found in broccoli sprouts, sulforaphane glucosinolate (SGS), as a factor in preventing multiple diseases, including several types of cancer, high blood pressure, macular degeneration and stomach ulcers.

Questions about validity of HOPE TOO vitamin E study

A study published in the March 16 issue of Journal of the American Medical Association (JAMA) suggesting that a "daily-dose" of vitamin E (400 international units) among high-risk (chronically ill) cardiovascular patient populations is associated with a greater risk of heart failure is being challenged by leading health researchers around the country who claim the study lacks the adequate research and controlled sampling audience to justify this conclusion.

More research on Vitamin E surprises scientists

50 years of research into the supposed benefits of taking vitamin E has extolled its antioxidant potential to offer a variety of potential health benefits, including reducing the risk of Alzheimer's, cancer and heart disease.

Selenium, vitamin E and the tomato nutrient lycopene have been shown to reduce prostate cancer

Greater levels of selenium, vitamin E and the tomato nutrient lycopene have been shown to reduce prostate cancer in one out of every four Caucasian males - those who inherit a specific genetic variation that's particularly sensitive to oxidative stress.

Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

Artemisinin could selectively kill cancer cells while leaving normal cells unharmed

Researchers at the University of Washington have blended the past with the present in the fight against cancer, synthesizing a promising new compound from an ancient Chinese remedy that uses cancer cells' rapacious appetite for iron to make them a target.

Antioxidants do not prolong the survival of patients with amyotrophic lateral sclerosis, or Lou Gehrig’s disease

A review of recent studies suggests that antioxidant supplements, including vitamin E and selenium, do not prolong the survival of patients with amyotrophic lateral sclerosis, or Lou Gehrig’s disease.

New study finds that regular physical activity, mental stimulation, and a diet rich in antioxidants can help keep old dogs young

During the two-year longitudinal study, William Milgram, Ph.D., of the University of Toronto, Elizabeth Head, Ph.D., and Carl Cotman, Ph.D., of the University of California, Irvine and their colleagues found older beagles performed better on cognitive tests and were more likely to learn new tasks when they were fed a diet fortified with plenty of fruits, vegetables and vitamins, were exercised at least twice weekly, and were given the opportunity to play with other dogs and a variety of stimulating toys.
