BACKGROUND Non-missile traumatic brain injury (nmTBI) without macroscopically detectable lesions often results in cognitive impairments that negatively affect daily life. AIM To identify abnormal white matter projections in patients with nmTBI with cognitive impairments using diffusion tensor magnetic resonance imaging (DTI). METHODS DTI scans of(More)
PURPOSE To evaluate testicular enhancement patterns in various scrotal disorders at dynamic contrast medium-enhanced subtraction magnetic resonance (MR) imaging. MATERIALS AND METHODS Forty-two patients with scrotal symptoms (22 testicular diseases, 20 extratesticular scrotal disorders) underwent three-dimensional (3D) fast field-echo or fast spin-echo(More)
BACKGROUND The cerebral metabolism of patients in the chronic stage of traumatic diffuse brain injury (TDBI) has not been fully investigated. AIM To study the relationship between regional cerebral metabolism (rCM) and consciousness disturbance in patients with TDBI. METHODS 52 patients with TDBI in the chronic stage without large focal lesions were(More)
A research committee supported by the Japanese government conducted a nationwide survey on the epidemiology of acute encephalopathy in Japan using a questionnaire. A total of 983 cases reportedly had acute encephalopathy during the past 3 years, 2007-2010. Among the pathogens of the preceding infection, influenza virus was the most common, followed by human(More)
Quantitative analyses of cross-sectional areas of the thalami, caudate nuclei, and lentiform nuclei were performed in 29 preterm infants (16 males, 13 females; mean age 29.6 weeks, age range 27 to 24 weeks,) with periventricular leukomalacia (PVL). MRI was carried out in the infants between 9 and 18 months of corrected age and in 16 control infants.(More)
Angelman syndrome (AS) is a genetic disorder with characteristic clinical and EEG findings. We report here the results of long-term follow-up studies on the epileptic seizures and EEG findings of 23 cases of deletion type AS confirmed by FISH analysis, including seven cases previously reported by Matsumoto et al. in 1992. The age at last follow-up in 23(More)
Photosystem II (PSII) contains different extrinsic proteins required for oxygen evolution among different organisms. Cyanobacterial PSII contains the 33 kDa, 12 kDa proteins and cytochrome (cyt) c-550; red algal PSII contains a 20 kDa protein in addition to the three homologous cyanobacterial proteins; whereas higher plant PSII contains the 33 kDa, 23 kDa(More)
We performed analysis of KCNT1 in two unrelated patients with malignant migrating partial seizures in infancy. Both patients had intractable focal seizures since two months of age. Their seizures were characterized by a shift of epileptic focus during a single seizure and were resistant to most antiepileptic drugs but responded to vagus nerve stimulation in(More)
Eight necropsy cases of a "panencephalopathic" type of Creutzfeldt-Jakob disease (CJD) in the Japanese are reported. The reasons why this type should be discussed separately from other types of CJD are that there is primary involvement of the cerebral white matter as well as the cerebral cortex, and that the white matter lesion of one Japanese human brain(More)
