Researchers at the Institute of Biochemistry and Molecular Biology I of the Heinrich-Heine University, Düsseldorf, Germany, investigated the relationship between fruit and vegetable intake, plasma antioxidant micronutrient status and cognitive performance in healthy subjects aged 45 to 102 years. Their results, published in the August issue of the Journal of Alzheimer’s Disease, indicated higher cognitive performance ...

When the leptin-serotonin pathway is turned on in mice, the researchers found, appetite increases, the animals eat more, gain weight, and their bone mass increases. When the pathway is turned off, mice eat less, lose weight, and their bones weaken.

Pandemic swine flu can infect cells deeper in the lungs than seasonal flu can, according to a new study published today in Nature Biotechnology. The researchers, from Imperial College London, say this may explain why people infected with the pandemic strain of swine-origin H1N1 influenza are more likely to suffer more severe symptoms than those infected ...

A new study published in the September 11, 2009 issue of Science by researchers at the NYU School of Medicine reveals a conceptually novel mechanism that plays an important role in making human pathogens like Staphylococcus aureus and Bacillus anthracis resistant to numerous antibiotics. The study led by Evgeny A. Nudler, PhD, The Julie Wilson Anderson Professor of ...

Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it. A ...

A moderate aerobic exercise program, without weight loss, can improve insulin sensitivity in both lean and obese sedentary adolescents, according to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM). Insulin is a hormone produced in the pancreas that permits glucose to enter cells to be used for ...

New research from Columbia University Medical Center has illuminated a previously unknown leptin-serotonin pathway in the brain that simultaneously promotes appetite and bone mass accrual. The research, which explains how leptin – well-known appetite-suppressing hormone – acts in the brain, is published in the Sept. 4 issue of Cell. When the leptin-serotonin pathway is turned ...

Shanghai Research Center for Modernization of Traditional Chinese Medicine, Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai, China. Salvia miltiorrhiza and Panax notoginseng were both considered to be beneficial to cardiovascular diseases in traditional Chinese medicine and often used in combination. To ...

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. The Dutch study looked at several hundred people with no history of cardiovascular disease aged 85 over a five year period to see ...

Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these “trans fats” gum up the cellular machinery that keeps blood moving through arteries and veins. In the August 2009 issue of the international journal Atherosclerosis, University ...

Eat less, exercise more. Now there is new evidence to support adding another “must” to the weight-loss mantra: eat at the right time of day. A Northwestern University study has found that eating at irregular times — the equivalent of the middle of the night for humans, when the body wants to sleep — influences ...
