Level of cellular stress determines longevity of retinal cells

Stress can be adaptive. It can make you sharper, help you focus and it can even improve your performance. But too much of it can tax cells to the point where they can no longer cope and slowly self-destruct.

Oral delivery system for RNAi therapeutics

Researchers at the University of Massachusetts Medical School (UMMS) report on a novel approach to the delivery of small bits of genetic material in order to silence genes using "RNA interference"-and in the process, discovered a potent method of suppressing inflammation in mice similar to what occurs in a range of human diseases.

Urine proteome pattern may predict coronary artery disease

Proteome analysis, a screening requiring only a patient's urine specimen, shows promise as a reliable and noninvasive way to diagnose atherosclerosis and coronary artery disease in the future, according to research presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2009.

Research may bring drugs with triple the absorbing power and lower toxic risks

Drug makers might be able to triple the absorbing power of some medications and lower toxic risks of others, as a result of a study at the University of Maryland, Baltimore on how bile acids travel through the gut.

New idea for Parkinson's treatment

In a study that reveals the clearest picture to date of neuron death in Parkinson's disease, researchers at Columbia University Medical Center have found that a trio of culprits acting in concert is responsible for killing the brain cells.

Avian flu research sheds light on swine flu outbreak

A new study by University of Maryland researchers suggests that the potential for an avian influenza virus to cause a human flu pandemic is greater than previously thought. Results also illustrate how the current swine flu outbreak likely came about.

SUMO protein guides chromatin remodeler to suppress genes

In an in vitro study, led by Grace Gill, PhD, Tufts University School of Medicine, researchers discovered how a protein called SUMO (Small Ubiquitin-related Modifier) guides an enzyme complex that alters the structure of chromatin to regulate expression of genes.

Discovery of novel protein which, when over-expressed, leads to a dramatic increase in the generation of A-beta

A defining hallmark of Alzheimer's disease is the accumulation of the amyloid beta protein (A-beta), otherwise known as "senile plaques," in the brain's cortex and hippocampus, where memory consolidation occurs.

Nanoscopic 'pearl necklaces' track and attack cancer cells

A team of investigators at Purdue University has developed nanoscale probes that can help pinpoint the location of tumors and might one day be able to directly attack cancer cells.

Research brings new hope, old problems with Alzheimer's disease biomarkers

Brain imaging and cognitive tests may be the gold standards for tracking Alzheimer disease progression, but clinical trials using these procedures are expensive, risky, and time-consuming, making the development of reliable go-betweens a pressing goal for AD researchers.
