Key brain antioxidant linked to Alzheimer's and Parkinson's

A new case study by Mayo Clinic researchers provides preliminary evidence to suggest a component of green tea may lead to clinical improvement in patients with chronic lymphocytic leukemia (CLL). Findings are published online in Leukemia Research. more  

After divorce happiness levels decrease and may never completely rebound

A study published in the December issue of Psychological Science finds divorce leaves a lasting effect on our satisfaction levels. A person's happiness level drops as she or he approaches divorce and gradually rebounds over time. But the level of satisfaction does not return to baseline (the level of satisfaction felt prior to the divorce.) more

Blood test can accurately diagnose heart failure in patients with kidney dysfunction

A large-scale analysis has shown that a blood test previously found useful in diagnosing or ruling out heart failure in emergency room patients remains effective in patients with chronic kidney disease. The study also demonstrates that the test for a marker called NT-proBNP can identify patients at a higher risk for death, independent of kidney dysfunction. The report from investigators at the Massachusetts General Hospital (MGH) will appear in the January 3, 2006 Journal of the American College of Cardiology and is receiving early online release. more  

Mayo Clinic discovers two key players in cancer prevention and how they work

Mayo Clinic researchers have challenged the conventional teaching about a common cancer trait and in doing so, discovered how cells are naturally "cancer proofed." Their findings appear in today's early online edition of the Dec. 15 issue of the journal Nature. more

Langerhans cells regulate immune reactions in the skin  

Researchers at Yale School of Medicine have demonstrated that Langerhans cells in the skin, which had been thought to alert the immune system to pathogens, instead dampen the skin's reaction to infection and inflammation. more

New discovery may improve treatment of neurodegenerative diseases and type 2 diabetes 

Proteins are large molecular chains that move around cells carrying vital information on the activity of the organism. The role of each protein depends largely on the form it takes, but the proteins occasionally lose this form when they collide and bind with other proteins. They aggregate, and lose their function, growing continuously to form what are known as amyloid fibres. This causes neurodegenerative diseases, such as Parkinson's, Alzheimer's, and forms of spongiform encephalopathy, such as mad cow disease (BSE) and its human form, Creuzfeldt-Jacob disease. It also produces the pancreatic malfunctions that cause type 2 diabetes. more

Chromosome four contains genes that affect drinking behaviors in smokers

Alcoholism is a complex behavior that draws from both environmental and genetic factors. Researchers have found in a sample of smokers chromosomal regions that affect patterns of drinking behavior. more
