Enriched environments reportedly show neuroprotective effects. Here, we evaluated the effect of an enriched environment prior to cerebral ischemia on neuronal cell death and neurogenesis in rats. Male SD rats were housed under standard conditions (SC) or in an enriched environment (EE), then subjected to global ischemia. The Y-maze test and novel object(More)
In this report, we discuss whether the optimal electric field to promote the growth of armchairtype nanotubes (metallic character) evaluated using the previous Hückel-Poisson method can be applied at the tip of a nanotube in a realistic system. Setting the cross-section of a nanotube and the external field by the sheath, we estimate an effective area at the(More)
Measuring emotion usually involves use of questionnaires. However, a questionnaire method is unable to measure emotion in real time as questionnaires are executed after the experiments. Besides, the resolution time of the emotion rating is low. Therefore, we proposed a novel method of measuring emotion in real time and to classify the negative emotion(More)
