A six-year study of a special type of brain aneurysm -- the thrombotic aneurysm -- has led to a treatment "roadmap" that should mean better outcomes for patients with this unusual medical problem.
UCSF Medical Center neurosurgeon Michael Lawton, MD, headed the clinical research team. The findings are reported in the March 2005 issue of Neurosurgery.
Approximately 5 percent of the U.S. population develops a brain aneurysm at some time, and an even smaller percentage -- about 0.5 percent -- is diagnosed with a thrombotic aneurysm. An aneurysm is an outpouching or bulge in an artery that usually forms at a branch point. The bulge represents a weakened spot in the arterial wall, and without treatment there is a risk of hemorrhage leading to brain damage or death. A thrombotic aneurysm is unusual because it contains a blood clot.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
