Toxic proteins explain memory loss in Alzheimer's patients

Researchers at Northwestern University have discovered a molecular mechanism -- a tiny protein attacking nerve cells -- that could explain why the brain damage in early Alzheimer's disease results in memory loss and not other symptoms such as loss of balance or tremors.

Nanoscale switch could serve as sensor, medical tool

Improving significantly on an early prototype, Johns Hopkins University researchers have found a new way to join two unrelated proteins to create a molecular switch, a nanoscale "device" in which one biochemical partner controls the activity of the other.

Indoprofen may lead to new treatments for spinal muscular atrophy

A drug withdrawn from pharmacy shelves over 20 years ago may point the way to a new treatment for spinal muscular atrophy, or SMA, a muscle-wasting and often life-threatening childhood disease.

Rifampicin can prevent the formation of protein fibrils associated with Parkinson's disease

Researchers at the University of California, Santa Cruz, have shown that rifampicin, an antibiotic used to treat leprosy and tuberculosis, can prevent the formation of protein fibrils associated with the death of brain cells in people with Parkinson's disease. The drug also dissolved existing fibrils in laboratory tests.

T cells activated in the gut during inflammatory bowel disease can be re-routed to the liver and cause chronic liver disease

The authors explain this detour by showing that an attractant protein that normally directs T cells into the gut is aberrantly produced in the liver during PSC. T cells expressing the receptor for the protein are thus re-routed to the liver

Avastin plus Folfox4 chemotherapy significantly extends survival in second-line metastatic colorectal cancer

Genentech and Roche today announced that a randomized Phase III study of Avastin™ (bevacizumab) plus the FOLFOX4 chemotherapy regimen (oxaliplatin/5-FU/leucovorin), compared to FOLFOX4 alone, in second-line metastatic colorectal cancer patients achieved its primary endpoint of improving overall survival.

Low-glycemic load diets may make dieting easier

Low-glycemic load diets, those low in sugars with moderate levels of carbohydrates and not as low in fat and protein, may lower metabolism less when compared with low-fat diets, making the dieters feel less tired, cold and hungry, as well as improve cardiovascular risk factors

Movies help explain how proteins gather into clusters called amyloid fibrils

To get a better look at how proteins gather into clusters called amyloid fibrils – which are associated with important human diseases such as Alzheimer’s, Parkinson’s and the so-called prion diseases like Mad Cow – researchers at North Carolina State University decided to make movies.
