...hers implanted a drug-coated, flexible, metal-mesh tube called a drug-eluting stent into the superficial femoral artery in Erickson's thigh. Researchers hope the drug coating will make it more likely to prevent the blockage from recurring, as compared with uncoated stents, which fail to do so in about one...Chemical decoy shows promise for slowing Alzheimer's by acting as decoy

The resulting polymer-amyloid complex can then be broken down and removed by specialized cells i...Chemists identify immune system mechanism for methamphetamine binges
...y , the Society's peer-reviewed journal. In a test tube study designed to simulate the chemical reactions that occur with the drug when it enters the bloodstream, the researchers showed that methamphetamine reacts with glucose and proteins to form a larger-size "glycated" product.

... Cardiac catheterization requires threading a thin tube from the groin area to the heart's arteries, where a dye is released to produce contrast X-rays. The procedure also checks the function of heart valves and muscle, takes between 30 minutes and 45 minutes to perform, and requires almost an hour for re...American Thoracic Society Journal news tips for March 2005 (first issue)

A stent is a wire mesh tube used to prop open an artery and improve blood flow to the heart muscle. In recent years drug-eluting stents have been developed, which, as the name suggest, are coated with drugs that are slowly released and help keep the artery from reclosing, an oc...Vaginal hysterectomy leads to better outcomes than abdominal surgery
