Parkinson's Gene And The DiseaseA group of Parkinson's disease scientists concluded there are no observable differences between those who have two copies of the most common mutation of the recently discovered LRRK2 gene and those who have only one copy. Their study would be reported in the September edition of the Archives of Neurology.
In most diseases with a genetic cause or component, two copies of a bad gene lead to more severe visible manifestation of the disease.........Go to the Health-blog (Added on 9/12/2006 4:58:38 AM)
Enzyme Builds NeurotransmittersThe study, which was directed by Scripps Research Professor Benjamin Cravatt, Ph.D., is being reported in the September 8 issue of The Journal of Biological Chemistry.
The new study describes a pathway-different than the one previously suggested-for the biosynthesis of neurotransmitter lipids, N-acyl ethanolamines (NAEs), which include the endogenous cannabinoid ("endocannabinoid") anandamide. The high activity of the enzyme a/b hydrolase4........Go to the Health-blog (Added on 9/11/2006 9:30:56 PM)
Donor Limb Onto A Patient's BodyYears ago, the idea of attaching a donor limb onto a patient's body would have been the stuff of science fiction. But to date about two-dozen people around the world have received hand transplants. Thomas Tung, M.D., conducts research within this relatively unorthodox realm of surgery, investigating therapies that could potentially allow the body to accept donor tissue without the use of immunosuppressive medication.

Olive oil pill can cut prostate cancer riskA pill made from olive oil and herbs could dramatically reduce a man's chances of developing prostate cancer.
A trial at Columbia University in the US revealed the herbal supplement can reduce the rate at which prostate cancer cells grow and spread by nearly 80 per cent.
The results, reported in the medical journal Nutrition And Cancer, appear to confirm anecdotal evidence that the herbal mixture has powerful anti-cancer properties.

What Is Health?Health is the functional and/or metabolic efficiency of an organism, at any moment in time, at both the cellular and global levels. In any organism, health is the ability to efficiently respond to challenges (stressors) and effectively restore and sustain a "state of balance," known as homeostasis. Sickness is merely the absence of health. All organisms, from the simplest to the most complex, reside on a spectrum between 100% health and 0%........Go to the Health-blog (Added on 9/7/2006 6:04:22 PM)
