Isolation of Novel Isoforms of Estrogen Receptor Genes from Xenopus Gonad and Brain (2008)
Junshin Iwabuchi, Koji Arai, Shohei Miyata
We isolated four variants of ER α mRNA, two each from the brain and gonad of the Xenopus embryo (brain, bER α 1 and bER α 2; gonad, gER α 1 and gER α 2). The N-terminal-domain of ER α differed...
Search for a Stochastic Background of 100-MHz GravitationalWaves with Laser Interferometers (2008)
Akutsu, Tomotada, Kawamura, Seiji, Nishizawa, Atsushi, Arai, Koji, Yamamoto, Kazuhiro, Tatsumi, Daisuke, ...
This Letter reports the results of a search for a stochastic background of gravitational waves (GW) at 100 MHz by laser interferometry. We have developed a GW detector, which is a pair of 75-cm...
