Patients who undergo coronary artery bypass surgery are prescribed life-saving medications at discharge significantly less frequently than heart attack patients who receive less invasive angioplasty procedures, according to a new analysis by researchers at the Duke Clinical Research Institute.
These findings are important, the researchers said, because the drugs in question -- aspirin, ACE inhibitors, beta blockers and statins -- have been proven effective by multi-center clinical trials to reduce repeat cardiac events and death and therefore incorporated in established guidelines for care of heart attack patients. The researchers said much room exists for improving the usage rates of these life-saving drugs among all heart patients, including those who received angioplasty.
For example, the Duke team found that 65 percent of angioplasty patients received ACE inhibitors -- a class of blood vessel-relaxing drugs -- compared to only 44 percent of bypass patients. The cholesterol-lowering statins were prescribed for 76 percent of angioplasty patients and 62 percent of bypass patients.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
