MANHATTAN, Kan. -- Kansas State University researchers have developed a glue mixture that may reduce risks after laser vision correction surgery. Stacy Littlechild, a recent bachelor's degree graduate in biology originally from Wakeeney, is the lead author of two studies that describe a new protocol involving fibrinogen, riboflavin and ultraviolet light that could improve the safety of the corrective surgery. One study that demonstrates the ability of a glue to bind corneal surfaces has been published in the June edition of the journal Investigative Ophthalmology ...

CAMBRIDGE, MA -- To control the three-dimensional shape of engineered tissue, researchers grow cells on tiny, sponge-like scaffolds. These devices can be implanted into patients or used in the lab to study tissue responses to potential drugs. A team of researchers from MIT, Harvard University and Boston Children's Hospital has now added a new element to tissue scaffolds — electronic sensors. These sensors, made of silicon nanowires, could be used to monitor electrical activity in the tissue surrounding the scaffold, control drug release or screen drug candidates for their ...

Munich, Germany – A balloon pump inserted in the aorta is currently the most widely used support device in the treatment of cardiogenic shock and, since its introduction in 1968, has been used in several million people. However, there is still only limited evidence that the intraaortic balloon pump (IABP), one of the oldest medical devices in cardiology, is actually beneficial for the patient. Only a few registry studies and clinical trials have shown that the IABP can improve blood pressure and the perfusion of the coronary arteries. Based on these studies, international ...

MBL, WOODS HOLE, MA-- Squid's colorful, changeable skin enables the animal--and their close relatives, cuttlefish and octopus--to display extraordinary camouflage, the speed and diversity of which is unmatched in the animal kingdom. But how squid control their skin's iridescence, or light-reflecting property, which is responsible for the animal's sparkly rainbow of color, has been unknown. In a new study, MBL (Marine Biological Laboratory) researchers Paloma Gonzalez Bellido and Trevor Wardill and their colleagues report that nerves in squid skin control the animal's ...

Munich, Germany – Rates of stent thrombosis at three years were low and comparable between zotarolimus-eluting and sirolimus-eluting stents, according to findings from the PROTECT study described here today at ESC Congress 2012. Presenting the results, Professor William Wijns from the Cardiovascular Center in Aalst, Belgium, said that the decline in rates of stent thrombosis seen recently and in the PROTECT (Patient Related OuTcomes with Endeavor versus Cypher Stenting) study was probably explained by several factors, including "improvements in patient selection, procedural ...

Munich, Germany – Data from four French nationwide registries of STEMI (ST-elevation myocardial infarction) patients initiated five years apart and covering more than 15 years show that mortality rate decreased by 68% over this period, from 13.7% to 4.4%. Around one quarter of this mortality reduction could be attributed to a change in patient characteristics. Even after adjusting for the use of primary percutaneous coronary intervention (PCI) and reperfusion therapy, there still remained a substantial decrease in early mortality rate (>60%), underlining the importance ...

Munich, Germany – The German Aortic Valve Registry (GARY) was started in July 2010 and is the only registry so far to include both transcatheter aortic valve implantation (TAVI) and conventional aortic valve replacements and repair.(1) The intention is to deliver a complete picture of current and future practice of treating aortic valve disease and to deliver reliable data on the short and long-term outcome of different treatment strategies. This specifically includes data about quality of life before and after treatment besides numerous medical variables. Participation ...

Therefore, prevention of hypertension is essential to improving health and ...

Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. Now, armed with a unique proxy, an international team of researchers show that unusually cold winters in Central Europe are related to low solar activity - when sunspot numbers are minimal. The freezing of Germany's largest river, the Rhine, is the key. Although the Earth's surface overall continues to warm, the new analysis has revealed a correlation between periods ...

Munich, Germany – Consuming energy drinks can exert acute positive benefits on myocardial performance, according to research presented today at the ESC Congress by Dr Matteo Cameli from University of Siena.

A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste power resources and lose energy when they heat up, an ideal superconductor would continuously carry electrical current without losing any power. But creating a true superconductor is tricky. Though the concept of high temperature superconductors is more than two decades old, finding and controlling the right materials has been a challenge. Now Prof. ...

Vanderbilt University researchers studying interventions for adolescents and young adults with autism are reporting today that there is insufficient evidence to support findings, good or bad, for the therapies currently used. Although the prevalence of autism is on the rise, much remains to be discovered when it comes to interventions for this population, the researchers concluded. "Overall, there is very little evidence in all areas of care for adolescents and young adults with autism, and it is urgent that more rigorous studies be developed and conducted," said Melissa ...

The blanket of sea ice floating on the Arctic Ocean melted to its lowest extent ever recorded since satellites began measuring it in 1979, according to the University of Colorado Boulder's National Snow and Ice Data Center. On Aug. 26, the Arctic sea ice extent fell to 1.58 million square miles, or 4.10 million square kilometers. The number is 27,000 square miles, or 70,000 square kilometers below the record low daily sea ice extent set Sept. 18, 2007. Since the summer Arctic sea ice minimum normally does not occur until the melt season ends in mid- to-late September, ...
