Journal ArticleDOI
Crystal structure and dielectric and magnetic properties of BiCrO3 as a ferroelectromagnet
Seiji Niitaka,Masaki Azuma,Masaki Azuma,Mikio Takano,Eiji Nishibori,Masaki Takata,Makoto Sakata +6 more
TL;DR: In this article, the structure of BiCrO 3 at room temperature is a highly distorted perovskite-type one with monoclinic C2 symmetry which is the same as that of the ferroelectric phase in BiMnO 3.
Journal ArticleDOI
Stem Cell Defects in ATM-Deficient Undifferentiated Spermatogonia through DNA Damage-Induced Cell-Cycle Arrest
Keiyo Takubo,Masako Ohmura,Masaki Azuma,Go Nagamatsu,Wakako Yamada,Fumio Arai,Atsushi Hirao,Toshio Suda +7 more
TL;DR: Flow cytometric analysis revealed that this population is composed of Plzf-positive cells and exhibits quiescence and the side population phenotype, fulfilling general stem cell criteria, and ATM plays an essential role in maintenance of undifferentiated spermatogonia and their stem cell capacity by suppressing DNA damage-induced cell-cycle arrest.
Journal ArticleDOI
A perovskite containing quadrivalent iron as a charge-disproportionated ferrimagnet.
Ikuya Yamada,Ikuya Yamada,Kazuhide Takata,Naoaki Hayashi,Satoshi Shinohara,Masaki Azuma,Shigeo Mori,Shigetoshi Muranaka,Yuichi Shimakawa,Mikio Takano +9 more
Journal ArticleDOI
Coherence Factors in a High-Tc Cuprate Probed by Quasi-Particle Scattering Off Vortices
Tetsuo Hanaguri,Yuhki Kohsaka,M. Ono,Marianna Maltseva,Piers Coleman,Ikuya Yamada,Masaki Azuma,Mikio Takano,K. Ohishi,Hidenori Takagi +9 more
TL;DR: F Fourier-transform scanning tunneling spectroscopy is used to reveal a magnetic-field dependence in quasi-particle scattering interference patterns that is sensitive to the sign of the anisotropic gap, and provides insights into the nature of electron pairing as well as quasi- particle scattering processes in unconventional superconductors.
Journal ArticleDOI
Regulation of Reactive Oxygen Species by Atm Is Essential for Proper Response to DNA Double-Strand Breaks in Lymphocytes
Keisuke Ito,Keiyo Takubo,Fumio Arai,Hitoshi Satoh,Sahoko Matsuoka,Masako Ohmura,Masako Ohmura,Kazuhito Naka,Masaki Azuma,Kana Miyamoto,Kentaro Hosokawa,Yasuo Ikeda,Tak W. Mak,Toshio Suda,Atsushi Hirao +14 more
TL;DR: Atm-mediated ROS regulation is essential for proper DNA recombination, preventing immunodeficiency, and lymphomagenesis, and in vivo administration of NAC to Atm−/− mice restored normal T cell development and inhibited aberrant V(D)J recombination.
