OBJECTIVE Hippocampal sclerosis (HS) is observed in many intractable, mesial temporal lobe epilepsy (MTLE) patients. We aimed to delineate the internal structural changes (ISC) shown as loss of internal architecture in the hippocampus on 3-Tesla magnetic resonance imaging (3T-MRI) due to its higher spatial resolution. METHODS We studied 12 MTLE patients(More)
Ihara epileptic rat (IER) is an animal model of temporal lobe epilepsy (TLE) with genetically programmed microdysgenesis in the hippocampal formation. The neuronal microdysgenesis is thought to be a cause for recurrent spontaneous seizures. To identify differentially expressed genes in the hippocampus of IER in comparison to control Wistar rat, we performed(More)
Epileptogenic foci in the foot/leg motor area of cortex are rarely resected, due to the risks of the surgical procedures. A 31-year-old right-handed man with cortical dysplasia deep in the central sulcus suffered from disturbances in walking due to frequent daily seizures. Following subdural electrode implantation to define the epileptogenic area and assess(More)
The MEK/ERK pathways are critical for controlling cell proliferation and differentiation. In this study, we show that the MEK5/ERK5 pathway participates in osteoclast differentiation. ERK5 was activated by M-CSF, which is one of the essential factors in osteoclast differentiation. Inhibition of MEK5 by BIX02189 or inhibition of ERK5 by XMD 8-92 blocked(More)
PURPOSE Genetically epileptic model rats, Ihara epileptic rat (IER/F substrain), have neuropathologic abnormalities and develop generalized convulsive seizures when they reach the age of approximately 5 months. Because the neuromorphologic abnormalities are centered in the hippocampus, we expected to observe spatial cognitive deficits. The present study(More)
We report here an intractable epilepsy case with fairly typical clinicoradiological features of dysembryoplastic neuroepithelial tumor (DNT), which means onset of seizures at a young age accompanying a medial temporal cystic lesion enclosed in cortical dysplasia (CD). The medial cystic lesion was composed of two morphologically distinct components; one was(More)
