By taking continuous electrocardiogram (ECG) readings for 24 hours after treating heart attack patients, Duke University Medical Center researches have shown that giving a combination of a new drug that prevents platelets from clumping together, as well as a clot-busting drug, opens up clogged arteries faster and keeps them open longer.
The researchers found that giving the anti-clotting drug eptifibatide along with a half-dose tenecteplase (TNK) -- a genetically altered version of the commonly used clot-busting agent t-PA -- improved the speed and endurance of restored blood flow to the heart. Eptifibatide is one of a new class of drugs used to prevent the aggregation of platelets in the bloodstream, a process that can lead to the formation of new blood clots, causing potentially dangerous complications.
Duke cardiologists Matthew Roe, M.D., and Mitchell Krucoff, M.D., conducted an additional analysis on a subset of patients enrolled in a larger clinical trial comparing the dual-drug strategy with a TNK-only treatment. His analysis was unique in that he used a portable heart monitoring device which continuously recorded the heart?s electrical activity for 24 hours.

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...
