In vertebrates, sperm development and maturation are directly regulated by gonadal steroid hormone secretion. The relationships among the expression of genes encoding steroidogenic proteins and receptors for gonadotropins, and testicular steroid production have not yet been comprehensively determined in male teleosts. In this study, the changes in levels of(More)
Hypoxic tumors have been identified as appropriate indicators of tumor malignancy. However, no convenient plasma marker for hypoxic tumors has been described. Therefore, to identify a novel, convenient plasma marker for hypoxic tumors, we used microarray analysis to compare gene expression profiles of normoxic and hypoxic tumor tissues of mice bearing(More)
We have used outer cell potential measurement to record agonist-dependent cellular responses in cells engineered to express ligand-gated ion channels and grown on a microelectrode surface. Application of glutamate, a natural agonist, induced a complex and robust potentiometric response in cells expressing homomeric GluR-D glutamate receptor, but not in(More)
This paper introduces the first online and free framework for teaching and learning Japanese prosody including word accent and phrase intonation. This framework is called OJAD (Online Japanese Accent Dictionary) [1] and it provides three functions. 1) Visual, auditory, systematic, and comprehensive illustration of patterns of accent change (accent sandhi)(More)
We developed the very first online and free framework for teaching and learning Japanese prosody including word accent and phrase intonation. This framework is called OJAD (Online Japanese Accent Dictionary) [1], which provides three functions. Subjective assessment by teachers shows very high peda-gogical effectiveness of the framework. 1. The three(More)
We have developed the very first free online and free framework for teaching and learning Japanese prosody with features for word accent and phrase intonation. This framework is called OJAD (Online Japanese Accent Dictionary) [1], which provides three functions. 1) Visual, auditory, systematic, and comprehensive illustration of patterns of accent change(More)
To support Japanese prosody instruction, the Online Japanese Accent Dictionary (OJAD) [1] has been developed by using NLP and SLP techniques and it is maintained by our laboratory. Japanese is a very unique language in that word accent often changes due to its context. The OJAD was introduced to the Japanese language education community as the first(More)
