Microfluidic Device With Artificial Arteries Measures Drugs’ Influence on Blood Clotting

Atlanta, GA

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries.

Personalized Medicine Best Way to Treat Cancer, Study Argues

Atlanta, GA

A new study found evidence that assessing the route to cancer on a case-by-case basis might make more sense than basing a patient’s cancer treatment on commonly disrupted genes and pathways.
