A study led by UCSF neurologist S. Claiborne Johnston, MD, has shown that coiling of ruptured brain aneurysms is very effective during long-term follow-up, similar to outcomes with surgical clipping.
Although results of a previous trial suggested that coiling was superior to surgical clipping one year after treatment, a lack of data on long-term outcomes has been a major concern, according to Johnston. The study results are published in the June 2006 issue of the journal Stroke, a publication of the American Heart Association.
"Aneurysms are very serious. Half of those who suffer a ruptured aneurysm will die from it, and another 30 percent will be permanently disabled," Johnston said. "Aneurysms that rupture once are very likely to bleed again, so treatment is definitely indicated. However, there has been concern that coiling may not work as well to prevent new bleeding, and this has limited its use, particularly in the U.S."

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
