Transcription factor, cAMP response element-binding protein (CREB), which is phosphorylated by cAMP-dependent kinase via an increase in cAMP, and regulates gene transcription by binding to the cAMP response element (CRE) on target genes. We examined age-dependent alterations in the DNA-binding activity of CREB in rat brain regions, and the effects of(More)
By cutting the brachial plexus at a few levels on the side stimulated, it was verified that the first far-field component of SEPs with forepaw reference recording is generated in the brachial plexus in the cat. Incidentally, a reversal of the polarity of the earliest portion of the first component was observed with abduction of the upper arm to a high(More)
Studies on the clinical course of familial ALS suggest that the duration of illness is relatively consistent for each mutation but variable among the different mutations. The authors analyzed the relative amount of mutant compared with normal SOD1 protein in the erythrocytes from 29 patients with ALS with 22 different mutations. Turnover of mutant SOD1(More)
Expression of brain-derived neurotrophic factor (BDNF) mRNA is increased in the dorsal root ganglion (DRG) in response to peripheral inflammation. Nerve growth factor (NGF) from inflammatory tissue is thought to induce expression of BDNF. Recently, it was reported that the BDNF gene has eight non-coding exons that are transcribed independently into several(More)
Short latency SEPs recorded in hand-scalp, ear-scalp and upper neck-scalp leads with stimulation of the median nerve were examined in 27 normal subjects and in 11 selected patients with unilateral complete loss of position sense in order to provide information concerning the generator sources of these potentials. Evidences obtained from both normal subjects(More)
The initial positive component of the scalp-recorded somatosensory evoked potential to median nerve stimulation was studied in 12 patients with sensory impairment for all modalities of the unilateral extremities due to lesions at or above or below the thalamic level, taking the potentials obtained from eight normal subjects as control. In normal subjects,(More)
In both cats and dogs propidium iodide (PI) which fluoresces red was injected into the rectal striated sphincter muscle and bisbenzimide (BB) which fluoresces blue into the vesical striated sphincter muscle of the same animal. In both cats and dogs neurons labeled with PI were concentrated dorsomedially in Onuf's nucleus, while those labeled with BB were(More)
OBJECTIVE After microvascular decompression to treat hemifacial spasm (HFS), resolution of the HFS is often gradual. We carefully investigated the course of the gradual resolution of HFS and examined the differences between patients with and without postoperative HFS. METHODS One hundred seventy-five patients with HFS were monitored, for observation of 1)(More)
Effects of 2-mercaptoethanol on primary cultures of fetal mouse brain neurons have been investigated. The addition of 2-mercaptoethanol to the culture medium increased 6- or 200-fold the survival rates of embryonic day-16 murine striatum neurons and day-18 cerebral cortical neurons cultured in serum-free medium, respectively, and also induced neurite(More)
