While about 80 percent of people with epilepsy gain significant relief from drug therapy, the remaining 20 percent have seizures that cannot be controlled by medications. Many of these people have a particular type of epilepsy called partial epilepsy. A new study shows that people with partial epilepsy often have seizures controlled by medications for years before their seizures become drug-resistant. The study also found that periods when seizures stopped for a year or more are common in these patients.
"This study opens the door for early identification of patients who will later develop drug-resistant partial epilepsy, which may in turn allow us to identify ways of preventing some forms of epilepsy from ever becoming drug-resistant," says lead author Anne T. Berg, Ph.D., of Northern Illinois University in DeKalb, who is part of a large multicenter team directed by Susan Spencer, M.D., at Yale University in New Haven, Connecticut. The study was funded by the National Institute of Neurological Disorders and Stroke (NINDS) and appears in the January 28, 2003, issue of Neurology.*
In the new study, researchers looked at patients who had surgery for drug-resistant partial epilepsy to identify factors that predict when seizures will become intractable, or no longer controllable with medications. They also studied the incidence of previous seizure-free periods in this group. Partial epilepsy results from abnormal neuronal activity that originates in a single part of the brain, usually in one of the temporal lobes.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
