Functional magnetic resonance imaging may be more accurate than the polygraph for lie detection

When people lie, they use different parts of their brains than when they tell the truth, and these brain changes can be measured by functional magnetic resonance imaging (fMRI), according to a study presented today at the annual meeting of the Radiological Society of North America.

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.

New non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes

A key question after a cancer diagnosis is whether the cancer has spread to nearby lymph nodes. Researchers at the University of Michigan Comprehensive Cancer Center have found a new non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes, sparing some women an extra trip to the operating room.

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.

A new study will research the best way to treat women with psychosis who then become pregnant

The national study will look at the best clinical practice for treating pregnant women with schizophrenia and other psychosis by setting up an Australian wide database of pregnant women with schizophrenia and related disorders. The study will follow the woman and her baby during pregnancy up to the first year of the baby's life.
