Kato, Haruhisa, Suzuki, Mie, Fujita, Katsuhide, Horie, Masanori, Endoh, Shigehisa, Yoshida, Yasukazu, ...

Dynamic light scattering (DLS) is widely used for the evaluation of the particle size in the toxicity assessment of nanoparticles. However, the many types of DLS instruments and analytical procedures...

Involvement of C-22-Hydroxylated Brassinosteroids in Auxin-Induced Lamina Joint Bending in Rice (2009)

Nakamura, Ayako, Fujioka, Shozo, Takatsuto, Suguru, Tsujimoto, Masafumi, Kitano, Hidemi, Yoshida, Shigeo, ...

The rice lamina joint is ideal material for investigating the activity of brassinosteroids (BRs) and auxin because of its high sensitivity to these compounds. Using a series of rice BR biosynthetic...

Axonal {alpha}-synuclein aggregates herald centripetal degeneration of cardiac sympathetic nerve in Parkinson's disease (2008)

Orimo, Satoshi, Uchihara, Toshiki, Nakamura, Ayako, Mori, Fumiaki, Kakita, Akiyoshi, Wakabayashi, Koichi, ...

Degeneration of the cardiac sympathetic nerve occurs in both Parkinson's disease (PD) and dementia with Lewy bodies and begins early in the disease progression of PD, accounting for reduced cardiac...

Modification of the aromatic ring of the WNA analogues for expansion of the triplex recognition codes (2005)

Taniguchi, Yosuke, Nakamura, Ayako, Aoki, Eriko, Sasaki, Shigeki

Triplex-forming oligonucleotides (TFOs) are powerful tools for genomic research. The most stable triplex is formed by the interaction between TFOs and homopurine/homopyrimidine sequences in the...

Effects of 5-substituted pyrimidine nucleoside bases of WNA on stability of triplex DNA (2004)

Taniguchi, Yosuke, Nakamura, Ayako, Senko, Yusuke, Sasaki, Shigeki

Triplex-forming oligonucleotides (TFOs) are potential DNA-targeting molecules, but their recognizable duplexes are limited to homopurine:homopyrimidine sequences by interruption of pyrimidine bases...

Design and evaluation of novel nucleoside analogs (WNA) for specific formation of non-natural type triplexes containing a TA or CG interrupting site (2003)

Taniguchi, Yosuke, Senko, Yusuke, Kodama, Keiichi, Nakamura, Ayako, Sasaki, Shigeki

In a search of suitable recognition molecules for the formation of stable non-natural triplex DNA, we have developed the new nucleoside analogs (WNA, W-shape nucleoside analog) bearing an aromatic...

Compilation and Characterization of Arabiopsis thaliana Response Regulators Implicated in His-Asp Phosphorelay Signal Transduction (1999)

Imamura, Aya, Hanaki, Naoto, Nakamura, Ayako, Suzuki, Tomomi, Taniguchi, Mitsutaka, Kiba, Takatoshi, ...

His-Asp phosphorelays are evolutionary-conserved powerful biological tactics for intracellular signal transduction. Such a phosphorelay is generally made up of “sensor histidine (His)-kinases”,...

Response regulators implicated in His-to-Asp phosphotransfer signaling in Arabidopsis

Imamura, Aya, Hanaki, Naoto, Umeda, Hiroyuki, Nakamura, Ayako, Suzuki, Tomomi, Ueguchi, Chiharu, ...

The His to Asp phosphotransfer signal transduction mechanism involves three common signaling domains: the transmitter (or His-kinase), the receiver, and the histidine-containing phototransfer (HPt)...

Organ-Specific Expression of Brassinosteroid-Biosynthetic Genes and Distribution of Endogenous Brassinosteroids in Arabidopsis

Shimada, Yukihisa, Goda, Hideki, Nakamura, Ayako, Takatsuto, Suguru, Fujioka, Shozo, Yoshida, Shigeo

Brassinosteroids (BRs) are steroidal plant hormones that are essential for growth and development. There is only limited information on where BRs are synthesized and used. We studied the organ...

Brassinolide Induces IAA5, IAA19, and DR5, a Synthetic Auxin Response Element in Arabidopsis, Implying a Cross Talk Point of Brassinosteroid and Auxin Signaling

Nakamura, Ayako, Higuchi, Kanako, Goda, Hideki, Fujiwara, Makoto T., Sawa, Shinichiro, Koshiba, Tomokazu, ...

Despite numerous physiological studies addressing the interactions between brassinosteroids (BRs) and auxins, little is known about the underlying molecular mechanisms. We studied the expression of...

Detection of Capsular Antigen Production in Unencapsulated Strains of Staphylococcus aureus

Yoshida, Kosaku, Nakamura, Ayako, Ohtomo, Toshichika, Iwami, Sachiye

Of 91 compact-type strains of Staphylococcus aureus in regular serum soft agar (SSA), 82 converted diffuse-type growth in serum soft agar (pH adjusted to 6.0). With the addition of four different...
