New statin study shows arrested progression of atherosclerosis

The first study to use cutting edge magnetic resonance imaging to examine the effect of a statin - rosuvastatin (Crestor) - on the fatty plaques in arteries, was presented yesterday at the 75th European Atherosclerosis Society Congress. ORION revealed that rosuvastatin has a beneficial effect on the size and composition of fatty plaques in arteries (specifically the carotid artery in the neck). Fatty plaques that are vulnerable to sudden rupture can cause heart attacks and strokes without warning.

Pattern of gene expression predicts multiple drug resistance, treatment failure in pediatric leukemia

The discovery of a specific pattern of gene expression linked to multiple-drug resistance of leukemic cells is giving researchers crucial information into why standard therapies fail to cure some children with acute lymphoblastic leukemia (ALL). This finding, from investigators at St. Jude Children’s Research Hospital, could lead to development of drugs that would overcome that resistance.
