Accurate stent positioning does not require use of high-tech device
Once a coronary stent becomes blocked with scar tissue, the likelihood it will become blocked again is 30 percent to 80 percent. Inserting a second coronary stent that slowly releases anti-scarring medication can markedly cut that risk, according to a study in the just-published October 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.
Researchers also showed that it was unnecessary to thread a high-tech ultrasound device into the artery to guide precise placement of the drug-eluting stent. Instead, they reduced the risk of blood clotting by minimizing trauma to the artery--no stretching of the artery before or after the procedure, for example--and prescribing a double dose of anti-clotting drugs for two months.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
