In the treatment of coronary artery disease, a sirolimus drug-coated stent causes less inflammation than bare metal stents, according to preliminary research presented at the American Heart Association annual meeting by Loyola University Health System, Maywood, Ill.
“Inflammatory response is a sign of advancing heart disease, so the less inflammation the better,” said lead author Dr. Fred Leya, professor of medicine/cardiology, Loyola University Chicago Stritch School of Medicine.
Stents are small stainless steel coils or scaffolds which are used to keep blood vessels open and maintain blood flow to the heart. The drug-coated stent reduces the risk of restenosis (renarrowing) of blood vessels after angioplasty, a common problem with earlier stents, where 30 percent of arteries renarrowed. “Many times with the earlier stents, tissue cells grew too much scar tissue, renarrowing the artery that the stent was supposed to widen,” said Leya, director, interventional cardiology and director, cardiac catherization lab at Loyola. Leya said that the FDA-approved stent produces immediate results. “It is especially appropriate for diabetics, because they have smaller arteries and thus a greater risk of restenosis of coronary vessels following angioplasty,” he said.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
