Immune antibodies penetrate neurons to clear Alzheimer's-linked amyloid

Researchers at Weill Cornell Medical College have gotten much closer to understanding how immune-based therapies can treat Alzheimer's disease -- by studying how antibodies go inside brain cells to reduce levels of Alzheimer's-linked amyloid peptides that form plaques between neurons.

Simple blood test for BNP levels predictive of higher in-hospital mortality rates for heart failure patients

A simple blood test, beyond standard lab tests, taken at hospital admission strongly predicted in-hospital mortality risk for heart failure patients and may be useful in helping doctors decide which patients need higher-level monitoring and more intensive treatment.
