The basic helix-loop-helix genes Math3 and NeuroD are expressed by differentiating amacrine cells, retinal interneurons. Previous studies have demonstrated that a normal number of amacrine cells is generated in mice lacking either Math3 or NEUROD: We have found that, in Math3-NeuroD double-mutant retina, amacrine cells are completely missing, while ganglion(More)
The pituitary gland is composed of two distinct entities: the adenohypophysis, including the anterior and intermediate lobes, and the neurohypophysis, known as the posterior lobe. This critical endocrine organ is essential for homeostasis, metabolism, reproduction, and growth. The pituitary development requires the control of proliferation and(More)
The preventative effect of cisternal irrigation with milrinone against vasospasm was evaluated in 12 patients with subarachnoid hemorrhage (SAH) of World Federation of Neurosurgical Societies grade IV or V treated between September 1999 and September 2000. All aneurysms were clipped or embolized within 72 hours of the onset of SAH. Inlet and outlet tubes(More)
PURPOSE OF THE REPORT The purpose of this report was to investigate the potential of positron emission tomography using F-18 fluorodeoxythymidine (FLT-PET) in evaluating primary brain tumors. MATERIALS AND METHODS FLT-PET was performed in 25 patients with primary brain tumors. FLT uptake in the lesion was semiquantitatively evaluated by measuring the(More)
We report the case of a woman with intracranial metastasis from an esophageal gastrointestinal stromal tumor (GIST) with the mutation site in the 3' end of exon 11. Frontal craniotomy was performed with complete resection of the mass, followed by postoperative stereotaxic radiotherapy (SRT). Intracranial metastasis from GISTs is extremely rare; we found(More)
The purpose of this study was to evaluate the effects of the retinal environment and retinoic acid (RA) pretreatment on the differentiation of transplanted adult rat hippocampus-derived neural stem cells (AHSCs). AHSCs were transplanted into embryonic (E18) or neonatal (P6) rat retinal explants and the mixture was cultured for 2 weeks. Other AHSCs were(More)
OBJECTIVES To evaluate the validity of 3D dynamic pituitary MR imaging with controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA), with special emphasis on demarcation of pituitary posterior lobe and stalk. METHODS Participants comprised 32 patients who underwent dynamic pituitary MR imaging due to pituitary or parasellar(More)
OBJECTIVE Hemangioblastomas remain a surgical challenge because of their arteriovenous malformation-like character. Recently, indocyanine green (ICG) videoangiography has been applied to neurosurgical vascular surgery. The aim of this study was to evaluate the usefulness of tumor blood flow imaging by intraoperative ICG videoangiography in surgery for(More)
