It has been shown three different views in relativistic thermodynamics can be derived from the basic formulation proposed by van Kampen and Israel. The way to decompose energy-momentum into work and heat is not uniquely determined; the different choices result in different views. Also the definition of three dimensional volume causes ambiguity of thermodynamical quantities. The present paper shows various theories are obtained depending on the choice of these two factors.

A mediated amperometric enzyme electrode, which is constructed by immobilizing an enzyme behind a semipermeable membrane on the surface of a carbon paste electrode containing a mediator compound, has allowed a variety of bioelectrochemical studies in both applied and fundamental aspects such as biosensors, biofuel cells, and enzyme kinetics. This paper describes such bioelectrochemical studies in which we have been involved in these 40 years. © 2012 Elsevier Ltd. Source

Food shortages have once again become a serious problem, not only because of world population growth but also as a result of escalating demand for crops as a substrate for biofuels. The production of improved plant varieties, especially major crops such as rice, is urgently required to increase yield. The completion of the sequencing of the rice genome has made it possible to clone and analyze quantitative trait loci (QTLs). Furthermore, the development of high-throughput sequencing and genotyping technologies has improved spectacularly the accuracy of QTL analysis. In this review article, we focus on the potential roles of major QTLs in the selection for agronomic traits in rice and discuss the application of high-throughput technologies for high-resolution genetic analysis. © 2011 Elsevier Ltd.

ε-Poly-L-lysine (ε-PL) consists of 25-35 L-lysine residues with linkages between theα-carboxyl groups and the ε-amino groups. It exhibits antimicrobial activity against a spectrum of microorganisms, including bacteria and fungi. Because of its high levels of safety and biodegradability, it is used as a food preservative in several countries. We recently identified an ε-PL synthetase (Pls) as a membrane protein,and investigated the catalytic mechanism. Pls was found to be an unusual non-ribosomal peptide synthetase (NRPS)-like peptide synthetase producing ε-PL with chain-length diversity. In addition, transcriptional analysis of pls and a kinetic study of Pls further suggested that the Pls catalytic function is regulated by intracellular ATP, high levels of which are required for full enzymatic activity. Furthermore, it was found that acidic pH conditions during ε-PL fermentation are necessary for the accumulation of intracellular ATP, rather than inhibition of the ε-PL-degrading enzyme. Source


The evolution of the polyploid Triticum wheats is distinctive in that domestication, natural hybridization and allopolyploid speciation have all had significant impacts on their diversification. In this review, I outline the phylogenetic relationships of cultivated wheats and their wild relatives and provide an overview of the recent progress and remaining issues in understanding the genetic and ecological factors that favored their evolution. An attempt is made to view the evolution of the polyploid Triticum wheats as a continuous process of diversification that was initiated by domestication of tetraploid emmer wheat and driven by various natural events ranging from interploidy introgression via hybridization to allopolyploid speciation of hexaploid common wheat, instead of viewing it as a group of discrete evolutionary processes that separately proceeded at the tetraploid and hexaploid levels. This standpoint underscores the important role of natural hybridization in the reticulate diversification of the tetraploid-hexaploid Triticum wheat complex and highlights critical, but underappreciated, issues that concern the allopolyploid speciation of common wheat. © 2011 The Author.
