Nomura K, Uchida M, Kageura H, Shiokawa K, Yamana K
Dev Growth Differ . 2023 Jun; 28(3):311-319. PMID: 37282264
The reaggregation kinetics of frog (Xenopus laevis) cells prepared using several different dissociation procedures were monitored. Two distinct modes of cell adhesion were revealed, one mediated by Ca dependent cell-cell...

Shiokawa K, Tashiro K, Misumi Y, Yamana K
Dev Growth Differ . 2023 Jun; 23(6):589-597. PMID: 37281934
The rates of syntheses of 18S and 28S rRNA, 5S RNA, capped mRNA and 4S RNA were determined in isolated cells from pre- and post-gastrular embryos of Xenopus laevis. The...

Shiokawa K, Misumi Y, Yamana K
Dev Growth Differ . 2023 Jun; 23(6):579-587. PMID: 37281811
Isolated cells from Xenopus laevis embryos at various developmental stages were incubated with (methyl- H) methionine to label newly synthesized RNAs. Methylation of RNAs was studied by analyzing nuclease-digests of...

Nishio Y, Shiokawa K, Yamana K
Dev Growth Differ . 2023 Jun; 20(1):35-40. PMID: 37281173
Isolated cells of Xenopus laevis neurulae were labeled with H-uridine at three different temperatures (21°C, 30°C and 10°C), and the pattern of RNA synthesis was examined, using polyacrylamide gels. At...

Shiokawa K, Yamana K
Dev Growth Differ . 2023 Jun; 21(6):501-507. PMID: 37281112
The dorsal and ventral blastomeres of 4-celled embryos of Xenopus luevis were separated. During the next 14 hr in cultnre, the cell numbers of the progeny cell aggregates of the...

Elliott S, Breneman A, Colpitts C, Pettit J, Cattell C, Halford A, et al.
Geophys Res Lett . 2022 Oct; 49(15):e2022GL099655. PMID: 36247517
Microbursts are impulsive (<1 s) injections of electrons into the atmosphere, thought to be caused by nonlinear scattering by chorus waves. Although attempts have been made to quantify their contribution...

Miyoshi Y, Shinohara I, Ukhorskiy S, Claudepierre S, Mitani T, Takashima T, et al.
Space Sci Rev . 2022 Jun; 218(5):38. PMID: 35757012
This paper presents the highlights of joint observations of the inner magnetosphere by the Arase spacecraft, the Van Allen Probes spacecraft, and ground-based experiments integrated into spacecraft programs. The concurrent...

Nishiuchi M, Sakaki H, Dover N, Miyahara T, Shiokawa K, Manabe S, et al.
Rev Sci Instrum . 2020 Oct; 91(9):093305. PMID: 33003787
We have developed a novel discrimination methodology to identify ions in multispecies beams with similar charge-to-mass ratios, but different atomic numbers. After an initial separation by charge-to-mass ratios using co-linear...

Nose M, Matsuoka A, Kumamoto A, Kasahara Y, Teramoto M, Kurita S, et al.
Earth Planets Space . 2020 Aug; 72(1):111. PMID: 32831576
We investigate the longitudinal structure of the oxygen torus in the inner magnetosphere for a specific event found on 12 September 2017, using simultaneous observations from the Van Allen Probe...

Sci Rep . 2020 Feb; 10(1):3380. PMID: 32098993
The brightness of aurorae in Earth's polar region often beats with periods ranging from sub-second to a few tens of a second. Past observations showed that the beat of the...
