Pyridoxal 5′‐phosphate, the vitamin B6 derivative, acts as the coenzyme of many enzymes involved in amino acid metabolism. Exceptionally, this compound was found covalently bound to glycogen phosphorylase, the key enzyme in the regulation of glycogen metabolism. Although it is essential for the function of phosphorylase, its direct role has remained an enigma. We have recently found that the glucose moiety of pyridoxal (5′)diphospho (1)‐α‐D‐glucose, a conjugate of pyridoxal 5′‐phosphate and glucose 1‐phosphate through a pyrophosphate linkage, is transferred to the (...) nonreducing end of glycogen, forming a new α‐1,4‐glucosidic linkage. This finding emphasizes the importance of the direct phosphate‐phosphate interaction between the coenzyme and the substrate in the phosphorylase catalytic reaction. We have proposed a catalytic mechanism for phosphorylase in which the phosphate group of pyridoxal 5′‐phosphate acts as an electrophile to the phosphate group of glucose 1‐phosphate. This appears to represent the first instance of the direct involvement of a phosphate group in catalysis by enzymes. (shrink)

As its name implies, Vasubandhu’s _Vyākhyāyukti_ (VyY) explains the logic or methodology (_yukti_) of exegesis or sūtra interpretation (_vyākhyā_) and only survives in a Tibetan translation. In recent years, research on this treatise has been gradually accumulating. However, due to the difficulty of the Tibetan translation, some of the arguments therein have been misunderstood. In this article, after reviewing the general framework of Vasubandhu’s method of interpreting the sūtras, I will present a newly discovered parallel regarding his discussion of the (...) “purpose, _prayojana_” of the sūtras and reread it through a close philological examination of various sources in Sanskrit and Tibetan. Thus, this article will first elucidate the details of Vasubandhu’s explanation of the purpose of the Buddha’s preaching using synonyms and will clarify an aspect of his views on the Buddha’s word. In addition, concerning this “purpose,” I will elucidate the characteristics of the final chapter of this text, which provides stories about hearing the Buddha’s words with respect. By doing so, I would like to reveal the characteristics of the VyY as a manual for vivid preaching. (shrink)

This paper offers some ideas and methods of consensus building towards integration of values in flood control, environment, and landscape. These three factors sometimes oppose to each other in the process of construction of public infrastructure such as roadbuilding and river improvement. It is crucial to avoid or resolute conflicts between the government and the local people through project management with the consensus building process. In public works in Japan, flood control has been given priority over the environmental preservation and (...) the landscape conservation due to the perception that it is through flood control that the life and property of individuals are adequately protected. As a consequence, the landscape and the environment have been paid only lip‐service. In the case of the Ohashi River Project in Izumo region presented in this paper, however, the river repair process might entail a severe blow to the tourism industry and have a dramatic impact on the fishery resources of the region, which would be considered a major loss in terms of the urban development of the city. One of our concerns is thus to avoid any losses, through proper consideration of the relationship between the three crucial factors. In this paper, the author reports some ideas and methods that appear in “Basic Policy for the Development of the Area around Ohashi River” composed by the Matsue Review Committee on the Development of the Area around the Ohashi River, in which the author is involved as a committee member. The most important task of the Committee wasto search for the ideas and methods to harmonize the values of flood control, environment, and landscape. (shrink)

Alternative interpretations are proposed for the finding that market integration is positively related to fair behavior in experimental games. Market activities may produce market relevant concepts and stories that interpret experimental games as incidences of social exchange, and thus may enhance the relevance of (1) market-related preferences or (2) a decision heuristic designed for social exchange.

The COVID-19 pandemic has put in the foreground the dramatic actuality of global and local inequalities, undermining neo-liberal, communitarian, democratic or cosmopolitan projects of collective id...

西田幾多郎の哲学は、単なる宗教体験の表現ではない合理的世界観である。その全貌を解読する時、われわれは、西田哲学が封印したもう一つの視点を発見する。そこであらわになるのは、驚くべき「時間」の真相―時間幻 想である。.
