Risk factors for CCSVI are similar to risk factors for developing MS, UB study shows

A University at Buffalo study of 252 volunteers identified an association between chronic cerebrospinal venous insufficiency (CCSVI) and multiple sclerosis (MS) risk factors, including infectious mononucleosis, irritable bowel syndrome, and smoking. The findings suggest that CCSVI may be a vascular condition similar to MS, warranting f...

NASA's Swift finds a gamma-ray burst with a dual personality

Astronomers propose two exotic scenarios for the unusual cosmic explosion: a novel supernova billions of light-years away or an unusual collision within our own galaxy. The 'Christmas burst' was caused by either event, with observations suggesting a neutron star and rapid tightening of its orbit.

Promising and perilous? The ambivalent role of the CXCL12/ CXCR4 axis in heart repair

Researchers found that reducing CXCR4 levels correlated with reduced infarct size and inflammation, but impaired recovery of blood flow and neovascularization. The study suggests that localized approaches, such as injecting stem cells with higher CXCR4 levels or CXCL12 variants, may be more effective in heart repair.
