Dementia :: Long-term beta carotene supplementation may help prevent cognitive decline

Men who take beta carotene supplements for 15 years or longer may have less cognitive decline, according to a report in the November 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

MRSA :: Factor key to severity of community-associated methicillin-resistant staph infections identified

Newly described proteins in drug-resistant strains of the Staphylococcus aureus bacterium attract and then destroy protective human white blood cells—a key process ensuring that S. aureus survives and causes severe disease, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Lupus :: Research suggests targeted treatment strategies for lupus

New research provides clues about the causes of lupus symptoms and suggests specific new targeted treatment strategies, according to Nilamadham Mishra, M.D., from Wake Forest University Baptist Medical Center, in presentations this week at the American College of Rheumatology in Boston.

Heart :: Aging heart changes shape, shrinks and loses pumping function too

Researchers at Johns Hopkins have evidence to explain why the supposedly natural act of aging is by itself a very potent risk factor for life-threatening heart failure.

Antioxidant :: Antioxidants could provide all-purpose radiation protection

Two common dietary molecules found in legumes and bran could protect DNA from the harmful effects of radiation, researchers from the University of Maryland report. Inositol and inositol hexaphosphate (IP6) protected both human skin cells and a skin cancer-prone mouse from exposure to ultraviolet B (UVB) radiation, the damaging radiation found in sunlight, the team reported today at the American Association for Cancer Research Centennial Conference on Translational Cancer Medicine.

Obesity :: Possible link between obesity and viral infections

Experts don’t dispute the important role that diet and activity play in maintaining a healthy weight. But can poor eating habits and a less active lifestyle fully explain the prevalence of obesity in the United States today? That question has led some researchers to ask whether there might be other causes for this serious problem. In the October issue of Mayo Clinic Proceedings, researcher Richard Atkinson, M.D., asserts that there is a growing body of evidence demonstrating that viruses may play a role in causing obesity in humans.

Blood Pressure :: Elderly with high blood pressure less likely to get lifestyle modification advice from doctors

People older than 60 with high blood pressure are less likely than other groups of patients to receive advice from their doctors about lifestyle modifications that can help lower their blood pressure, a study by UNC researchers concludes.

Liver :: Plasma serotonin levels can correlate with degree of liver insufficiency

Liver cirrhosis is a worldwide disease with an incidence of 5 – 10% and represents a major health problem everywhere. Prognosis depends on the degree of liver damage and etiology of cirrhosis. Treatment is complex and often very expensive. Due to this, the attempts of researchers are focused on finding the most optimal therapeutic modalities, which depend mostly on the stage of cirrhosis.
