lthough Zn 2 ϩ is contained in large amounts in the synaptic terminals of hippocampal mossy fibers (MFs), its physiological role in synaptic transmission is poorly understood. By using the newly developed high-sensitivity Zn 2 ϩ indicator ZnAF-2, the spatiotemporal dynamics of Zn 2 ϩ was monitored in rat hippocampal slices. When high-frequency stimulation(More)
Although Zn2+ is contained in large amounts in the synaptic terminals of hippocampal mossy fibers (MFs), its physiological role in synaptic transmission is poorly understood. By using the newly developed high-sensitivity Zn2+ indicator ZnAF-2, the spatiotemporal dynamics of Zn2+ was monitored in rat hippocampal slices. When high-frequency stimulation was(More)
The new method proposed here recognizes activities performed by a group of users (e.g., attending a meeting, playing sports, and participating in a party) by using sensor data obtained from the users. Note that such group activities (GAs) have characteristics that differ from those of single user activities. For example, the number of users who participate(More)
The unspliced human immunodeficiency virus type 1 (HIV-1) RNAs are translated as Gag and Gag-Pol polyproteins or packaged as genomes into viral particles. Efficient translation is necessary before the transition to produce infective virions. The viral protein Rev exports all intron-containing viral RNAs; however, it also appears to enhance translation.(More)
Artemisia annua L. is a commercial source of artemisinin. Nevertheless, artemisinin content within the plant is relatively low and varies depending on genotype and environment. To broaden the genetic variability, the mutation effect of 12C-ion beam irradiation on A. annua was examined. Irradiation at 2.5 Gy had a slight lethal effect to nodal segments while(More)
