The mechanism by which adult neural stem cells (NSCs) are established during development is unclear. In this study, analysis of cell cycle progression by examining retention of a histone 2B (H2B)-GFP fusion protein revealed that, in a subset of mouse embryonic neural progenitor cells (NPCs), the cell cycle slows between embryonic day (E) 13.5 and E15.5(More)
In the present study, we examined the visual accommodation of subjects who were gazing fixedly at 3D images from two different displays: a cathode ray tube (CRT) while wearing special glasses and a liquid crystal display (LCD) while not wearing special glasses. The subjects in this experiment were two healthy people aged 22 and 39 years, all with normal(More)
The self-choice effect refers to the fact that self-chosen items are remembered better than experimenter-assigned items (Takahashi, 1991). The present study investigated the hypothesis that (a) response choice involves relational processing as activation of both target and context items, and (b) such activated context items are effective as potential(More)
In compliance with good manufacturing practice, the use of process analytical technology based on near-infrared spectroscopy requires that a calibration model be maintained to assure the continuous estimation accuracy. The present research proposes knowledge integration-based operationalization of calibration model maintenance. A model maintenance framework(More)
We analyzed the results of the clock drawing test (CDT) in patients with Alzheimer's disease (AD) by quantitative and qualitative methods to evaluate its significance for cognitive function screening. We administered the CDT and mini-mental state examination (MMSE) to a total of 156 AD patients, and CDT performance was scored quantitatively in accordance(More)
The visibility of Japanese characters on the liquid crystal displays in mobile phones was studied by measurements of reading time and visual distance, and subjective evaluations. Graphic text was used to prepare various samples with various character heights of 1, 1.25, 1.5, 1.75, 2 and 2.25 times greater than the width of the characters. The vertical(More)
