studies that addition of the polymer serves as an effective "decoy" for attracting the circulating beta amyloid proteins away from the neuron-like cells. 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. This product is then rec...

Most advanced CT scanner improves imaging of heart, avoids need for surgical inspection
... 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...

Stents and going with the flow
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...
