Excessive activation of glutamate receptors accompanied by Ca2+ overloading is thought to be responsible for the death of neurons in various conditions including stroke and epilepsy. Neurons also die if deprived of important growth factors and trophic influences, conditions sensitive to certain oncogene products such as the Bcl2 protein. We now demonstrate(More)
During periods of stress, cells depend on a transient, highly conserved, and regulated response to maintain homeostasis. This "heat shock response" is mediated transcriptionally by a multigene family of heat shock factors (HSF). The presence of multiple HSF suggests that activation of a given HSF is stress-specific. Using Western blot analysis, we have(More)
BACKGROUND AND PURPOSE Glutamate receptor antagonists can produce protection against the neurotoxicity of excessive glutamate stimulation. However, antagonism of the postreceptor processes that produce cell damage may provide a longer window of opportunity for protecting neurons after the initiation of excitotoxic injury. Among various processes that have(More)
Although a neurotoxic role has been postulated for the beta-amyloid protein (beta AP), which accumulates in brain tissues in Alzheimer's disease, a precise mechanism underlying this toxicity has not been identified. The peptide fragment consisting of amino acid residues 25 through 35 (beta AP25-35), in particular, has been reported to be toxic in cultured(More)
Distinct subpopulations of neurons in the brain contain one or more of the Ca(2+)-binding proteins calbindin D28k, calretinin, and parvalbumin. Although it has been shown that these high-affinity Ca(2+)-binding proteins can increase neuronal Ca2+ buffering capacity, it is not clear which aspects of neuronal physiology they normally regulate. To investigate(More)
Slices (n = 45) from the somatosensory cortex of mouse (P8-13) generated spontaneous bursts of activity (0.10 +/- 0.05 Hz) that were recorded extracellularly. Multiunit action potential (AP) activity was integrated and used as an index of population activity. In this experimental model, seizure-like activity (SLA) was evoked with bicuculline (5-10 microM)(More)
OBJECT The object of this study was to evaluate surgical outcome in a select group of patients with medically refractory epilepsy who had undergone corpus callosotomy combined with bilateral subdural electroencephalography (EEG) electrode placement as the initial step in multistage epilepsy surgery. METHODS A retrospective chart review of 18 children(More)
A consecutive, retrospective analysis of seizure control and quality of life was performed among 83 pediatric patients undergoing epilepsy surgery at Children's Hospital of Wisconsin. Seizure outcomes were generally favorable, with 68.7% class I outcomes; class II, 12%; and class III, 19.3%. Seizure freedom was highest among temporal lobectomies (84.2%) and(More)
The antiepileptic drug felbamate has demonstrated efficacy against a variety of seizure types in the pediatric population, particularly seizures associated with Lennox-Gastaut syndrome. Postmarketing experience, however, revealed serious idiosyncratic adverse effects not observed during clinical trials, including aplastic anemia and liver failure. As a(More)
