Researchers find potential treatment for Huntington's disease

Research into the controversial drug thalidomide reveals that the mechanism through which the drug causes limb defects is the same process which causes it to damage internal organs and other tissues. The article, published in Bio-Essays, outlines the challenges surrounding thalidomide research and claims that confirmation of a 'common mechanism' could lead to new treatments for Leprosy, Crohn's Disease, AIDS and some forms of cancer. more  

Depression as deadly as smoking, but anxiety may be good for you

A study by researchers at the University of Bergen, Norway, and the Institute of Psychiatry (IoP) at King's College London has found that depression is as much of a risk factor for mortality as smoking. more

Monetary gain and high-risk tactics stimulate activity in the brain

Monetary gain stimulates activity in the brain. Even the mere possibility of receiving a reward is known to activate an area of the brain called the striatum. A team of Japanese researchers report in the January 2010 issue of Cortex, published by Elsevier, the results of a study in which they measured striatum activation in volunteers performing a monetary task and found high-risk/high-gain options to cause higher levels of activation than more conservative options. They also found levels of activation to increase with the amount of money owned. more  

Scientists discover cells that control inflammation in chronic disease

A new type of immune cell that can be out of control in certain chronic inflammatory diseases, worsening the symptoms of conditions like psoriasis and asthma, is described for the first time this week in the Journal of Clinical Investigation. more

Drug therapy more cost-effective than angioplasty for diabetic patients with heart disease  

Many patients with diabetes should forego angioplasties for heart disease and just take medicine instead, according to a new National Institutes of Health study led by Stanford University School of Medicine researcher Mark Hlatky, MD. more

Cross-country runabouts - immune cells on the move  

Scientists from the Max Planck Institute (MPI) of Biochemistry in Martinsried near Munich, Germany, have now deciphered the mechanism that illustrates how these mobile cells move on diverse surfaces. "Similar to a car, these cells have an engine, a clutch and wheels which provide the necessary friction," explains Michael Sixt, a research group leader at the MPI of Biochemistry. The results, which were developed in cooperation with colleagues from the MPI for Metals Research in Stuttgart, Germany, have now been published in Nature Cell Biology. more

Researchers identify gene mutations underlying risk for most common form of Parkinson's Disease

Two genes containing mutations known to cause rare familial forms of Parkinsonism are also associated with the more common, sporadic form of the disease where there is no family history, researchers have found. more
