Ito S, Taga Y, Hiratsuka K, Takei S, Kitagawa D, Kobatake S, Miyasaka H.
PMID: 26221633
Chem Commun (Camb). 2015 Sep 18;51(72):13756-9. doi: 10.1039/c5cc03663a. Epub 2015 Jul 29.

3D single-molecule tracking revealed that the translational diffusion of guest dyes in poly(2-hydroxyethyl acrylate) thin films on glass substrates was confined in a horizontal layer at a distance longer than 300-700 nm from the surface of the substrate. This...

Light regulated transcription in higher plants.

Journal of plant research

Hiratsuka K, Chua NH.
PMID: 27520053
J Plant Res. 1997 Mar;110(1):131-9. doi: 10.1007/BF02506852.

Studies on the function of plant promoters have demonstrated the presence of regulatorycis-acting elements that mediate developmental or environmental signals. Analysis of many light-responsive genes showed thatcis-acting elements responsible for light regulated transcription are located within the 5' upstream...

Microbial Transformation of Carbazole to Anthranilic Acid by Pseudomonas stutzeri.

Bioscience, biotechnology, and biochemistry

Hisatsuka K, Sato M.
PMID: 27315727
Biosci Biotechnol Biochem. 1994 Jan;58(1):213-4. doi: 10.1271/bbb.58.213.

This study examined the microbial transformation of carbazole (CZ) by an isolated bacterium that can use CZ as a sole carbon and nitrogen source. The strain identified as Pseudomonas stutzeri produced a large amount of anthranilic acid (AA) from...

Implementation of a redox microarray: an experimental model for future nanoscale biomolecular computing using integrated circuits.

IEE proceedings. Nanobiotechnology

Hiratsuka M, Aoki T, Morimitsu H, Higuchi T.
PMID: 16468923
IEE Proc Nanobiotechnol. 2003 Jun;150(1):9-14. doi: 10.1049/ip-nbt:20030518.

The possibility of constructing high-density parallel computing architectures using molecular electronics technology is explored. By employing molecular computing devices, new circuitsystem integration could be realised. To clarify the proposed concept, an experimental model of a redox microarray is presented....

Synthesis and properties of 5,10,15,20-tetrakis[4-(alkoxysilyl)phenyl]porphyrins: an application of selective deprotection of benzaldehyde diethyl acetals in the presence of alkoxysilyl groups.

Dalton transactions (Cambridge, England : 2003)

Ishida S, Ito M, Horiuchi H, Hiratsuka H, Shiraishi S, Kyushin S.
PMID: 20820609
Dalton Trans. 2010 Oct 21;39(39):9421-6. doi: 10.1039/c0dt00427h. Epub 2010 Sep 03.

Selective deprotection of 4-(alkoxysilyl)benzaldehyde diethyl acetals 1a-1c in the two-solvent system of hydrochloric acid and chloroform gave 4-(alkoxysilyl)benzaldehydes 2a-2c in good yields. Under these conditions, undesired hydrolysis of the alkoxysilyl group was minimized. The reaction of benzaldehydes 2a and...
