We have treated undifferentiated mouse embryonic stem (ES) cells with all-trans retinoic acid (RA) to induce differentiation in vitro into neuron-like cells with good cell viability for use as a graft. Furthermore, we asked whether the RA-induced neuron-like cells restored neurological dysfunction. To this end, the cells were transplanted into right(More)
We induced neural cells by treating cynomolgus monkey embryonic stem (ES) cells with retinoic acid. The treated cells mainly expressed betaIIItubulin. They further differentiated into neurons expressing neurofilament middle chain (NFM) in elongated axons. Half of the cells differentiated into Islet1+ motoneurons in vitro. The monkey ES-derived neural cells(More)
The authors reviewed magnetic resonance (MR) images in seven cases of germinoma in the hypothalamoneurohypophyseal axis (HNA). The intrasellar portions were clearly identified in six germinomas. Two small germinomas of these six were located only in the neurohypophysis. The major parts of the four large germinomas were located below the optic chiasm, and(More)
We developed neural tube-like structures accompanying neural crest-like cells by treating embryonic stem (ES) cells with retinoic acid. The structures contained pseudostratified Nestin+Vimentin+ neuroepithelial cells surrounded by Masson staining+ basement membrane. betaIIItubulin+Synaptophysin+ mature neurons and glial fibrillary acidic protein (GFAP)+(More)
Mouse embryonic stem (ES) cells were transfected with a MASH1 expression vector and G418-resistant cells were selected. The MASH1-transfected cells became neuron-like appearance and expressed betaIIItubulin and panNCAM. Glial fibrillary acidic protein (GFAP) and galactocerebroside (GalC)-expressing cells were rarely detected. Half of the neural cells(More)
Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) is a free radical scavenger used for acute ischemic stroke. However, it is not known whether edaravone works only as a free radical scavenger or possess other pharmacological actions. Therefore, we elucidated the effects of edaravone on human brain microvascular endothelial cells (HBMECs) by 2 dimensional(More)
The efficacy of intravenous administration of 400 mg carboplatin/m(2) body surface area over 60 minutes combined with hyperbaric oxygenation (HBO) therapy (0.2 MPa for 60 min) was investigated in 6 Japanese patients (aged 36-67 years) with malignant or brainstem gliomas. Plasma ultra-filtrate samples were analyzed by high-performance liquid chromatography(More)
A rare case of solitary fibrous tumor, located wholly within the fourth ventricle, is reported. A 57-year-old male presented with headache and nausea. The preoperative magnetic resonance images revealed a well circumscribed mass in the fourth ventricle that exhibited a low intensity on T1-weighted images and homogeneously enhanced with gadolinium. Vertebral(More)
Growth hormone-secreting pituitary adenoma is usually benign, and distant metastases are extremely rare. A case of growth hormone-secreting pituitary adenoma with multiple dural metastases is reported. A 53-year-old male was initially admitted to our hospital complaining of visual loss, presenting a pituitary abnormal mass with suprasellar extension. At the(More)
The aim of this study was to evaluate the clinical manifestations and prognostic factors of progressive brain injury following trauma. We reviewed the records of 779 patients with head injury who had an admission Glasgow Coma Scale of 9 or more; 70 (7.0%) developed progressive brain injury as evidenced on serial CT scans. Of these 70 patients, 19 (27.1%)(More)
