[Deletions of mitochondrial DNA in Kearns-Sayre syndrome].
Single large-scale deletions of mitochondrial DNA (mtDNA) are found in 70 to 80% of Kearns-Sayre syndrome (KSS) patients. Most deletions are flanked by direct repeats up to 13 nucleotides in length.… Expand
Determination of language dominance with synthetic aperture magnetometry: comparison with the Wada test
Synthetic aperture magnetometry (SAM) is a spatial filtering technique that enables demonstration of the spatiotemporal distribution of oscillatory changes (synchronization and desynchronization) in magnetoencephalography signals elicited by specific brain activation. Expand

To investigate the etiological factors responsible for intellectual impairment and mood changes in patients with myotonic dystrophy (DM), we evaluated 14 patients with DM by means of… Expand
Treatment of Kearns‐Sayre syndrome with coenzyme Q10
We studied the metabolism of coenzyme Q10 (CoQ) and the effects of CoQ therapy in five patients with Kearns-Sayre syndrome (KSS). Although the mitochondrial fraction was increased in muscles from KSS… Expand
Improvement of abnormal pyruvate metabolism and cardiac conduction defect with coenzyme Ql0 in Kearns‐Sayre syndrome
In a patient with Kearns-Sayre syndrome, concentration of coenzyme Ql0, a component of the mito-chondrial electron transport system, was decreased in serum and in the mitochondrial fraction of… Expand

Many CoQ trials for mitochondrial encephalomyopathy are reported, however, the action of CoQ in the central nervous system is unknown. We administered CoQ to a patient with MELAS, and decreasing CSF… Expand
Familial amyloid polyneuropathy associated with the transthyretin Cys114 gene in a Japanese kindred.
A Japanese kindred with dominantly inherited amyloid polyneuropathy, commonly called familial amyloid polyneuropathy (FAP), has been identified. Amyloid protein was transthyretin (TTR) related and… Expand
