An experimental gene transfer technique shut down cell re-growth in the arteries interior lining and reduced the inflammatory response – two main causes of re-narrowing of newly opened blood vessels, researchers report in todays rapid access issue of Circulation: Journal of the American Heart Association.
The process that opens blocked blood vessels – either inflating a tiny balloon to force open the narrowed vessel (angioplasty) or inserting a tiny mesh tube called a stent to serve as a scaffold to widen the opening – can damage the delicate lining of blood vessels, says Seppo Yla-Herttuala, M.D., Ph.D., professor of molecular medicine at the University of Kuoppio, Finland.
"This damage – rather than a progression of heart disease – is believed to cause rapid growth of new cells in the vessel wall, which can cause re-blockage, or restenosis, in the vessel," he says.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
