Time-resolved luminescence spectra in colorless anatase TiO2 single crystal (2005)
関谷, 隆夫, Wakabayashi, K., Yamaguchi, Y., Sekiya, Takao, Kurita, S.
Time-resolved luminescence was measured on a colorless anatase single crystal under pulsed-laser excitation. The time evolution of luminescence is composed of fast and slow components with time...
Up-converted luminescence of cyanine dye J-aggregates (2005)
関谷, 隆夫, Miyasue, K., Honma, T., Kurita, S., Sekiya, Takao, Nakajima, M., ...
A J-band photoluminescence of cyanine dye J-aggregates was observed under excitation below the band gap. This emission is not due to two-photon absorption. The luminescence intensity becomes weaker...
Relaxation process in anatase TiO2 single crystals with different colors (2004)
関谷, 隆夫, Sekiya, Takao, Tasaki, M., Wakabayashi, K., Kurita, S.
Photoluminescence and excitation spectra were measured on anatase single crystals with different colors; colorless, pale blue, dark blue, dark green and yellow. Time evolution of the emission in...
Optical and electric properties of Nb-doped anatase TiO2 single crystal (2004)
関谷, 隆夫, DasMulmi, D., Sekiya, Takao, Kamiya, N., Kurita, S., Murakami, Y., ...
Nb-doped anatase TiO2 single crystal has been grown by chemical vapour transport method. Raman spectra shows that the obtained crystal with Nb of 0.08 wt% has typical anatase structure. An absorption...

Maintenance of Transcription Factor DataBase TFDB by (1998)
Masako Kaizawa, Takahiro Nobukuni, Masami Horikoshi, Yoshiyuki Kuchino, Takao Sekiya
Introduction TFD [1]--[4] was a very useful and required database for molecular biologists analyzing transcription mechanisms and gene expressions, which was maintained by David Ghosh at NCBI until...

A DNA fragment of about 2000 base pairs carrying the gene for tRNA1Ile has been cloned from a total Eco RI endonuclease digest of Escherichia coli DNA. Sequence analyses revealed that about the first...
Nucleotide Sequence in the Promoter Region of the Escherichia coli Tyrosine tRNA Gene*
Sekiya, Takao, Khorana, H. Gobind
The sequence of 29 nucleotides immediately preceding the starting point of transcription of the E. coli tyrosine tRNA gene has been determined. This is: [Formula: see text] The sequence contains...

Hbo1 Links p53-Dependent Stress Signaling to DNA Replication Licensing▿
Iizuka, Masayoshi, Sarmento, Olga F., Sekiya, Takao, Scrable, Heidi, Allis, C. David, Smith, M. Mitchell
Hbo1 is a histone acetyltransferase (HAT) that is required for global histone H4 acetylation, steroid-dependent transcription, and chromatin loading of MCM2-7 during DNA replication licensing. It is...
