Recombinant tumor necrosis factor α (rTNFα; optimal dose 1000 U/ml) significantly increased the density of epidermal growth factor receptor (EGF-R) in three of four glioma cell lines in culture as determined by binding analysis of anti-EGF-R monoclonal antibody (mAb) 425. Since enhancement of EGF-R expression by rTNF-α was inhibited when cells were treated(More)
OBJECTIVE The aim of the present study was to assess a new technique of surgical microscope-based indocyanine green (ICG) videoangiography (VAG) to confirm the patency of the anterior communicating artery (AcomA) after clipping AcomA aneurysms. METHODS Aneurysmal clipping of five cases of unruptured, broad-neck AcomA aneurysm was performed using the Carl(More)
OBJECTIVE We present herein the intraoperative indocyanin green videoangiography (ICGVAG) findings for three cases of cerebellar hemangioblastoma (HB). CASES Cerebellar HB was detected in three patients presenting with symptoms of vertigo and/or headaches and diagnosed on the basis of preoperative magnetic resonance imaging (MRI) and cerebral angiographic(More)
The intraoperative findings of an indocyanine green videoangiography (ICG-VAG) study of a cavernous angioma located in the optic chiasm are reported. A 23-year-old Japanese man suddenly developed visual field loss, and magnetic resonance imaging suggested the presence of a suprasellar tumor in contact with the optic chiasm. Preoperative angiography did not(More)
We morphologically investigated animal skin exposed to W/O emulsion containing 10 wt % ultrafine TiO(2) particles that had been characterized. After 4 h, exposed skin was investigated by light microscopy, confocal laser scanning microscopy (CLSM) and electron microscopy with energy-dispersive X-ray spectrometry (EDX). Light microscopic evaluation was also(More)
Glioblastoma multiforme (GBM), the most malignant class of glial neoplasm (grade IV in WHO criteria), carries the worst clinical prognosis among primary brain tumors in adults. To identify a set of genes involved in the tumorigenesis of GBM, we evaluated expression profiles of GBM tissues from 11 patients using a cDNA microarray representing 25,344 human(More)
INTRODUCTION Phacomatosis pigmentovascularis is a rare congenital condition characterized by vascular malformation associated with extensive pigmented nevi. Even though it forms a large, prominent skin lesion, therapy for phacomatosis pigmentovascularis is rarely discussed. To the best of our knowledge, this is the first report of phacomatosis(More)
This study evaluated preliminary findings on the efficacy of polyethylene glycol (PEG) hydrogel dural sealant capping for the prevention of cerebrospinal fluid (CSF) leakage and pneumocephalus during deep brain stimulation (DBS) surgery in the semisupine position. Group A consisted of 5 patients who underwent bilateral subthalamic nucleus (STN)-DBS surgery(More)
A 58-year-old female with gastric cancer presented with left chronic subdural hematoma (CSH) without history of head injury. Magnetic resonance imaging revealed left CSH with atypical findings such as abnormal dural enhancement and swelling of the left cerebral hemisphere. One month after gastrectomy, motor aphasia and right hemiparesis developed.(More)
