Microbial life inhabits deeply buried marine sediments, but the extent of this vast ecosystem remains poorly constrained. Here we provide evidence for the existence of microbial communities in ~40° to 60°C sediment associated with lignite coal beds at ~1.5 to 2.5 km below the seafloor in the Pacific Ocean off Japan. Microbial methanogenesis was indicated by(More)
Examined hypothalamic-pituitary-adrenal axis (HPA axis) function in 30 children with attention-deficit hyperactivity disorder (ADHD) by measuring the diurnal variation and response to the dexamethasone suppression test (DST) of saliva cortisol. Normal diurnal saliva cortisol rhythm was found in only 43.3% of the ADHD children. DST showed suppression in(More)

OBJECTIVE To evaluate the relevance of hypometabolism in the hippocampal head to the pathophysiology of memory impairment. BACKGROUND Neurofunctional imaging studies with an image reslicing technique provided by using software suggest that dysfunction of the amygdalohippocampal system causes memory impairment. However, metabolic and morphologic profiles(More)
Chronologic and morphometric changes in the inferior olivary nucleus of the human medulla oblongata were studied in eight cases of primary pontine hemorrhage with different survival periods. To measure the olivary areas and analyze the neuronal and glial components, an optic electronic planimeter was used. A desk-top computer was also used for the(More)
Thirty-seven small thalamic hemorrhages (less than 2 cm) were classified into four types depending on topographic location. Patients with posterolateral lesions had severe sensory and motor disability as well as the worst prognosis. Anterolateral lesions resulted in mild prefrontal signs with milder sensory and motor impairment. Medial hematomas disturbed(More)
This study examines the incidence rate of setback in 80 autistic children, the correlation between the type of onset and clinical features, developmental level and prognosis based on an originally developed questionnaire. Moreover, this study seeks to investigate the possibility that infantile autism might be classified into subgroups by the type of onset.(More)
Chordomas are most commonly located in the extradural region. A 56-year-old man presented with a large chondroid chordoma located totally within the intradural retroclival region. The tumor was resected via the petrosal approach. Five years after subtotal removal, the residual tumor showed no sign of regrowth despite the fact that radiation therapy had not(More)
In order to clarify the relationship between benign epilepsy of children with centro-temporal EEG foci (BECCT) and febrile convulsions (FC), we compared the previous and family histories of FC of one hundred children with BECCT, aged 3 years to 13 years, with those of 100 non-epileptic controls matched for age and sex. The incidences of FC in children with(More)
