We have shown previously that epidermal growth factor (EGF) plus fibroblast growth factor (FGF2) expands the neural precursor cells in the ependyma of the normal adult rat spinal cord in vivo. To investigate the therapeutic effect of these factors on spinal cord injury (SCI), we administered EGF, FGF2, EGF plus FGF2, or artificial cerebrospinal fluid (aCSF)(More)
This study examined whether continuous intramedullary infusion of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), or neurotrophin-3 (NT-3) had either an early neuroprotective effect or a delayed effect on regeneration after spinal cord injury (SCI) in adult rats. BDNF, NGF, NT-3 or vehicle was infused at a rate of 625 ng/h into the SCI(More)
We propose a method of describing human activities from video images based on concept hierarchies of actions. Major difficulty in transforming video images into textual descriptions is how to bridge a semantic gap between them, which is also known as inverse Hollywood problem. In general, the concepts of events or actions of human can be classified by(More)
We investigated the mitogenic effect of continuous intrathecal infusion of epidermal growth factor (EGF) or fibroblast growth factor 2 (FGF2) on ependymal precursor cells of the adult rat spinal cord in vivo. Either EGF, FGF2, EGF plus FGF2, or artificial cerebrospinal fluid (aCSF) was infused at a flow rate of 0.5 microl/h (15 ng/h of EGF or FGF2) for 3 or(More)
We report an unusual case of a 56-year-old woman with a supratentorial anaplastic ependymoma localized in the parenchyma without continuity with the ventricular system and brain surface. The patient presented with vertigo, and a calcified mass was detected in the left temporal parenchyma. Five years later, she had seizure of the right extremities. Computed(More)
