A possible biomarker for colon cancerAn abnormality of chromosomes long linked to diseases of aging has, for the first time, been associated with colon cancer in people 50 years old and younger, an age group commonly considered young for this disease.
The finding may provide an early alert for younger colon cancer patients and could prompt new research into colon cancer prevention and therapy strategies, say Mayo Clinic researchers.
The study results will be presented at 10........Go to the Colon-cancer-blog (Added on 10/28/2007 3:04:46 PM)

Severely Restricted Diet Linked to Physical Fitness into Old AgeSeverely restricting calories leads to a longer life, researchers have proved.
New research now has demonstrated for the first time that such a diet also can maintain physical fitness into advanced age, slowing the seemingly inevitable progression to physical disability and loss of independence.
The study, using a rat model of life-time caloric restriction, showed that the diet reduces the amount of visceral fat, which expresses........Go to the Weight watcher's blog (Added on 10/24/2007 7:44:02 PM)
Link between obesity and viral infectionsExperts dont dispute the important role that diet and activity play in maintaining a healthy weight.
