On the Steadily Rotating Spirals (2006)
Guo, Jong-Shenq, Nakamura, Ken-Ichi, Ogiwara, Toshiko, Tsai, Je-Chiang
We study an autonomous system of two first order ordinary differential equations. This system arises from a model for steadily rotating spiral waves in excitable media. The sharply located spiral...
Ogiwara, Toshiko, Nakamura, Ken-Ichi
This paper is concerned with nonlinear diffusion equations related to a model of the motion of screw dislocations on crystal surfaces. We prove the existence, uniqueness and asymptotic stability of a...

Normal serum from the hagfish Eptatretus burgeri strongly enhanced the phagocytic activity of homologous peritoneal macrophages against rabbit erythrocytes (RRBC). Such phagocytosis was effectively...
Nakamura, Ken-ichi, Wilkerson, Curtis G., Witman, George B.
The alpha beta dimer and the gamma subunit of the Chlamydomonas outer arm dynein were solubilized by treating isolated axonemes with 0.6 M KCI, and purified by sucrose density gradient...
Mechanism of Adenosine Triphosphate-dependent Ca2+ Uptake of Brain Microsomes (1974)
NAKAMURA, Ken-ichi, KONISHI, Kazuhiko
Brain microsomes prepared with 10 mM NaHCO3 showed ATP-dependent Ca2+ uptake but not Mg2+, Ca2+-dependent ATPase [EC 3.6.1.3] activity. The incorporation of γ32P of ATP into microsomal lipid, which...
Regulation of DNA Replication Machinery by Mrc1 in Fission Yeast
Nitani, Naoki, Nakamura, Ken-ichi, Nakagawa, Chie, Masukata, Hisao, Nakagawa, Takuro
Faithful replication of chromosomes is crucial to genome integrity. In yeast, the ORC binds replication origins throughout the cell cycle. However, Cdc45 binds these before S-phase, and, during...

Rad51 suppresses gross chromosomal rearrangement at centromere in Schizosaccharomyces pombe
Nakamura, Ken-ichi, Okamoto, Aya, Katou, Yuki, Yadani, Chie, Shitanda, Takeshi, Kaweeteerawat, Chitrada, ...
Centromere that plays a pivotal role in chromosome segregation is composed of repetitive elements in many eukaryotes. Although chromosomal regions containing repeats are the hotspots of...
