Timing often matters when it comes to epileptic seizures that can occur after surgery designed to stop them. A multicenter study led by researchers at Jefferson Medical College has found that patients who had an initial seizure within the first four months of surgery were less likely to do as well in the long term as those individuals who did not.
"A patient has surgery to remove some brain tissue, hoping to cure his epilepsy, and has a seizure a week or a month or a year later, and wonders, What does this mean? Has surgery failed?" says Daniel H. Parish, a second-year medical student at Jefferson Medical College of Thomas Jefferson University in Philadelphia, who is the lead author of the report. "We wanted to know if the timing of seizures after surgery was related to long-term outcome." He reports the study findings April 13, 2005 at the annual meeting of the American Academy of Neurology in Miami Beach.
Mr. Parish, Michael R. Sperling, M.D., Baldwin Keyes Professor of Neurology at Jefferson Medical College of Thomas Jefferson University and director of the Jefferson Comprehensive Epilepsy Center, and their colleagues at six other medical centers studied 387 patients who had epilepsy surgery, following these patients for an average of 4.4 years. Although about two-thirds of patients experienced at least one seizure some time after surgery, a similar percentage ultimately stopped having seizures.

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
