The biological effects of type I serine/threonine kinase receptors and Smad proteins were examined using an adenovirus-based vector system. Constitutively active forms of bone morphogenetic protein (BMP) type I receptors (BMPR-IA and BMPR-IB; BMPR-I group) and those of activin receptor-like kinase (ALK)-1 and ALK-2 (ALK-1 group) induced alkaline phosphatase(More)
The authors report a case of subependymal giant cell astrocytoma associated with tuberous sclerosis in a 15-year-old boy. Computed tomographic scans showed a large intraventricular mass with peritumoral calcification and a cyst in the left lateral ventricle. Left dominant unilateral hydrocephalus was also revealed. Magnetic resonance images clearly(More)
Persistent vegetative state after severe brain damage was studied epidemiologically in 110 cases from 1973 to 1976. The causes of brain damage were varied. More than one-third of the cases were due to trauma, and about one-fifth were the result of vascular accidents. Three year observation revealed that 65% of the patients died during this period. Mean(More)
The pathogenesis of chronic subdural hematoma is not fully understood. It is thought that fibrinolytic hyperactivity within the hematoma capsule plays an important role. However, since this hyperactivity has not been found in the systemic blood, accelerated fibrinolysis is thought to occur only locally. To evaluate coagulant and fibrinolytic activities in(More)
PURPOSE This study assessed the reproduction of excursive tooth contacts with a SAM2 "P" articulator set up with the aid of computerized axiography. MATERIAL AND METHODS Articulator excursive tooth contacts were compared with intraoral excursive contacts identified with occlusogram wax. The maxillary casts were mounted with a kinematic face-bow, and the(More)
Intracranial neurinomas of the jugular foramen and the hypoglossal canal are relatively rare. Most reports have been of either single cases or of only two or three patients, and few large series exist in the literature. Although some of these tumors present palsies of the ninth, tenth, and eleventh cranial nerves as a jugular foramen syndrome, this is not(More)
A 69-year-old man was admitted because of sudden onset of consciousness disturbance. Neurological examination on admission revealed slightly disturbed consciousness, sensory aphasia and right hemiparesis. CT scan disclosed a hematoma in the left posterior temporal lobe. Left carotid angiograms showed dural AVF of the transverse/sigmoid sinus fed mainly by(More)
