Women with heart attacks benefit from stenting
...his was explained by their older age, smaller body surface
area, increased frequency of other diseases and risk factors, and the greater occurrence of in-hospital complications. Major adverse cardiac events remained greater in women than men. The fact that the women had a smaller body size and smaller vess...
Painless test using teardrops may speed diagnosis of Sjgren's syndrome
... syndrome. Using a new analytical technique called surface
enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS), the researchers identified about 10 protein biomarkers that appear to be specific for Sjgrens. In addition to helping diagnose the disease, the tear biomarkers also...

Scientists discover how Ebola virus infects cells
...virus co-opts and uses to cut up one of the virus' surface
proteins. Once this protein is snipped apart, the virus is free to begin multiplying. The scientists applied broad-spectrum enzyme inhibitors to mammalian cells before exposing them to Ebola virus. When one specific cellular enzyme, cathepsin B, was ...
Golfers' yips may be movement disorder
