To evaluate the role in synaptic plasticity of ryanodine receptor type 3 (RyR3), which is normally enriched in hippocampal area CA1, we generated RyR3-deficient mice. Mutant mice exhibited facilitated CA1 long-term potentiation (LTP) induced by short tetanus (100 Hz, 100 ms) stimulation. Unlike LTP in wild-type mice, this LTP was not blocked bythe NMDA(More)
Interleukin-6 (IL-6) is pleiotropic cytokine involved in many central nervous system disorders including stroke, and elevated serum IL-6 has been found in acute stroke patients. IL-6 is implicated in the inflammation, which contributes to both injury and repair process after cerebral ischemia. However, IL-6 is one of the neurotrophic cytokines sharing a(More)
Sera from patients with myasthenia gravis (MG) were screened for autoantibodies to skeletal muscle-specific antigens by immunoprecipitation assay, using rhabdomyosarcoma and leukemia cell lines. Eleven of 61 MG sera immunoprecipitated a rhabdomyosarcoma-specific 70-kDa protein, which was identified as the voltage-gated K+ channel 1.4 (Kv1.4). This antibody(More)
OBJECTIVE To investigate the clinical, genetic, and neuroradiologic presentations of idiopathic basal ganglia calcification (IBGC) in a nationwide study in Japan. METHODS We documented clinical and neuroimaging data of a total of 69 subjects including 23 subjects from 10 families and 46 subjects in sporadic cases of IBGC in Japan. Mutational analysis of(More)
This study examines the alteration of oligodendrocyte progenitor cells (OPCs), mature oligodendrocytes (OLGs) and myelination after focal ischemia in the rat brain. Adult male Sprague-Dawley rats were subjected to 90-min occlusion of the middle cerebral artery, followed by reperfusion time of up to 2 weeks. The infarct core showed a rapid and progressive(More)
Binding of cyclic AMP to the regulatory subunit of cyclic AMP-dependent protein kinase (PKA) is an essential step in cyclic AMP-mediated intracellular signal transduction. This binding is, however, rapidly inhibited in the acute phase of cerebral ischemia, indicating that the signal transduction via PKA is very vulnerable to ischemia, although this signal(More)
A 76-year-old man was admitted to our hospital presenting with fever, redness and pain in both the periocular regions, and disturbance of consciousness. He had neck stiffness, and cerebrospinal fluid analysis suggested aseptic meningoencephalitis. Laboratory tests showed increased levels of C-reactive protein, soluble IL-2 receptor (sIL-2R) and MPO-ANCA.(More)
BACKGROUND AND PURPOSE The JELIS trial examined the preventive effect of eicosapentaenoic acid (EPA) against coronary artery diseases. Hypercholesterolemic patients received statin only (no EPA group: n=9319) or statin with EPA (EPA group: n=9326) for around 5 years. EPA significantly suppressed the incidence of coronary events in previous analysis. Herein,(More)
BACKGROUND Few multiple case studies of the effects of deep brain stimulation for camptocormia associated with Parkinson's disease have been reported. Although deep brain stimulation was in some cases not effective against camptocormia, it is unclear in which types of patients it was effective in treating camptocormia. OBJECTIVE We treated 4 Parkinson's(More)
BACKGROUND AND PURPOSE Plasma D-dimer levels are elevated during the acute phase of cerebral infarction (CI). We investigated whether the D-dimer level on admission and other clinical characteristics could be used to predict the poor outcome of patients with acute CI. METHODS The clinical characteristics and plasma D-dimer levels measured within 3 days of(More)
