In a major study conducted at 20 centers in the United States and Europe, a bioartificial liver developed by researchers at Cedars-Sinai Medical Center reduced mortality significantly among patients suffering from acute liver failure, the dramatic loss of liver function that can cause death in days or even hours. Study results are published in the May issue of Annals of Surgery.
This is the first large-scale, prospective, randomized, multi-center trial examining the effectiveness of any artificial liver support. Currently, standard treatment consists of intensive, supportive care intended to keep patients alive long enough that the liver might recover spontaneously or a donor organ will become available for transplantation.
Acute liver failure is diagnosed when a massive loss of hepatic cells causes severe liver dysfunction and life-threatening complications within six months of the onset of symptoms. When this dysfunction occurs within the first eight weeks after onset, liver failure is termed "fulminant." When it occurs in the period between eight weeks and six months, it is "subfulminant" (or late-onset). In either case, few patients survive the resulting fluid buildup in the brain, catastrophic bacterial infections, multi-organ failure, blood-clotting abnormalities, respiratory problems, kidney failure or other potential complications. It is estimated, in fact, that up to 80 percent of patients will die unless they receive a liver transplant.

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...
