A role of Ca2+/calmodulin-dependent protein phosphatase (calcineurin) in induction of long-term potentiation (LTP) was investigated using its selective inhibitor, FK506, in visual cortical slices of young rats. Field potentials or excitatory postsynaptic potentials (EPSPs) to test stimulation of white matter were recorded extra- or intracellularly from(More)
We report on seven Japanese families with spinocerebellar ataxia type 6 (SCA6) carrying small CAG repeat expansions in the calcium channel alpha1A subunit gene. The number of the expanded CAG repeat, ranged from 22 to 25, showed no intergenerational instability and had a significant inverse correlation with the age of onset. The clinical features of these(More)
Anti-glomerular basement membrane glomerulonephritis after radiotherapy for early prostate cancer Anti-glomerular basement membrane (GBM) glomerulone-phritis is characterized by rapidly progressive glomerulone-phritis (RPGN) with anti-glomerular basement antibodies. Although the underlying pathogenesis is not completely understood, factors such as smoking,(More)

A 40-year-old man was admitted to our hospital because of dysarthria, difficulty swallowing, double vision and weakness of both upper extremities. There were no detectable anti-AChR antibodies. He was diagnosed with seronegative myasthenia gravis (SNMG) based on a positive edrophonium test and positive waning on repetitive stimulation. Thereafter(More)
OBJECTIVES The aim of this study was to demonstrate circadian blood pressure trends and to evaluate autonomic function in patients with spinocerebellar degeneration (SCD). MATERIALS AND METHODS We performed 24-h ambulatory blood pressure monitoring (ABPM) on 10 patients from seven Japanese families with spinocerebellar ataxia type 6 (SCA6), 10 patients(More)
We measured cerebrospinal fluid (CSF) levels of dehydroepiandrosterone sulfate (DHEAS) by radioimmunoassay in seven patients with multi-infarct dementia (MID), fourteen age- and gender-matched non-demented patients with a history of cerebral infarction and fifteen age- and gender-matched patients without neurological disorders. The levels of DHEAS in CSF of(More)
Serial electroencephalograms (EEGs) and somatosensory evoked potentials (SEPs) were carried out in a 36-year-old man with isolated ACTH deficiency. Before treatment with glucocorticoids, the EEGs displayed bilateral diffuse 5-6 Hz theta waves, and SEPs demonstrated a decreased amplitude. Following treatment with glucocorticoids, the EEGs showed gradual(More)
To elucidate a role of Ca2+/calmodulin-dependent protein kinase II (CaMKII) in induction of long-term potentiation (LTP), KN-62, a selective inhibitor for CaMKII, was injected into layer 2/3 neurons of sliced visual cortex obtained from young rats. Tetanic stimulation (5 Hz, 1 min) applied to the white matter after the KN-62 injection induced long-term(More)
