TL;DR: The behavior of p-bpa-monosaccharide complexes in vivo after injection of the complex solution is described, and the complex formation constants obtained by the UV method in pH 7.4 solution are described.
Abstract: To increase the solubility of p-boronophenylalanine (p-bpa) in neutral pH solution, the complex formation of p-bpa with some monosaccharides has been studied by 11B-NMR and UV spectroscopy. The complex formation constants (log K) obtained by the UV method in pH 7.4 solution are 2.43 (fructose), 2.19 (mannitol), 1.28 (galactose), 1.10 (mannose), and 0.85 (glucose), respectively. One hundred milligrams of p-bpa is able to dissolve in 3 ml of 0.3 M fructose solution at pH 7.98. Based on the results obtained, the behavior of p-bpa-monosaccharide complexes in vivo after injection of the complex solution is described.

TL;DR: In this paper, a spheroidal graphite cast iron specimen was prepared for visualizing hydrogen, since it consists of basic microstructures of steels such as ferrite and pearlite, and the amount of hydrogen and the existing states of hydrogen in the cast iron were analyzed by thermal desorption spectrometry.
Abstract: The distribution and desorption processes of hydrogen and deuterium have been visualized by secondary ion mass spectrometry (SIMS). The present article deals with four principal points: (1) visualizing the hydrogen distribution, (2) visualizing the hydrogen desorption process from each metallurgical microstructure under various holding times at 25 °C, (3) visualizing the hydrogen desorption process during heating, and (4) determining the correspondence between desorption profiles and desorption sites. A spheroidal graphite cast iron specimen was prepared for visualizing hydrogen, since it consists of basic microstructures of steels such as ferrite and pearlite. Hydrogen and deuterium were occluded into the cast iron. The amount of hydrogen and the existing states of hydrogen in the cast iron were analyzed by thermal desorption spectrometry (TDS). The TDS analyses show that the hydrogen desorption has two peaks, namely, the low- and high-temperature peaks corresponding to trap activation energies of 21.6 and 105.8 kJ/mol, respectively. The SIMS analyses of the specimen cooled after heating to 100 °C, 200 °C, and 300 °C reveal that the hydrogen desorbs from the ferrite after heating to 100 °C, from the pearlite and the interfaces between the ferrite and the graphite after heating to 200 °C, and from the pearlite after heating to 300 °C. The graphite remains, trapping hydrogen after heating to 300 °C. On the basis of TDS and SIMS results, the relationship between the desorption profile and desorption sites was identified; that is, the low-temperature peak corresponds to ferrite, pearlite, and graphite/ferrite interfaces, while the high-temperature peak corresponds to graphite.

TL;DR: The conditions for early Earth conducive for the emergence of life, with particular regard to far-from-equilibrium geochemical systems and the thermodynamic and chemical phenomena that are driven into being by these disequilibria are discussed.
Abstract: The 8th meeting of the NASA Astrobiology Institute’s Thermodynamics, Disequilibrium, Evolution (TDE) Focus Group took place in November 2014 at the Earth-Life Science Institute, at the Tokyo Institute of Technology, Japan. The principal aim of this workshop was to discuss the conditions for early Earth conducive for the emergence of life, with particular regard to far-from-equilibrium geochemical systems and the thermodynamic and chemical phenomena that are driven into being by these disequilibria.
