An insulin-releasing system that is responsive to glucose
- Y. Ito, M. Casolaro, Kenji Kono, Y. Imanishi
- Chemistry
- 1 November 1989
Abstract A membrane system consisting of poly(acrylic acid)-grafted porous cellulose film and glucose oxidase was synthesized for insulin delivery in response to glucose concentration. The principle… Expand
pH-Sensitive Gating by Conformational Change of a Polypeptide Brush Grafted onto a Porous Polymer Membrane
- Y. Ito, Yasushi Ochiai, Yong Soon Park, Y. Imanishi
- Chemistry
- 19 February 1997
Benzyl glutamate NCA was graft-polymerized onto a porous poly(tetrafluoroethylene) membrane in order to study the effects of pH and ionic strength on permeation rate. The membrane was first… Expand
Patterned immobilization of thermoresponsive polymer
- Y. Ito, G. Chen, Yan-Qing Guan, Y. Imanishi
- Materials Science
- 14 May 1997
The thermoresponsive polymer poly(N-isopropylacrylamide) was immobilized in a specific pattern on a polystyrene matrix by photolithography. N-Isopropylacrylamide was copolymerized with acrylic acid.… Expand
In vitro selection of a ligase ribozyme carrying alkylamino groups in the side chains.
- N. Teramoto, Y. Imanishi, Y. Ito
- Chemistry, Medicine
- Bioconjugate chemistry
- 3 November 2000
A novel ligase ribozyme was in vitro selected from a random-sequence RNA library including N(6)-aminohexyl-modified adenine residues in place of natural adenine residues. This ribozyme mediated the… Expand
Photocontrolled Gating by Polymer Brushes Grafted on Porous Glass Filter
- Y. S. Park, Y. Ito, Y. Imanishi
- Materials Science
- 24 March 1998
Polymethacrylate-containing spiropyran was grafted on a glass filter to control permeation of organic liquid by photoirradiation. The glass filter was at first coupled with… Expand

frontotemporal region of the scalp. The lesions are usually recognized within the first few years of life, and are nonscarring, permanent, and not associated with neurological deficit. There is one… Expand
Recent developments in olefin polymerizations with transition metal catalysts
- Y. Imanishi, N. Naga
- Materials Science
- 1 October 2001
Abstract Discovery of effective homogeneous transition metal catalysts for olefin polymerization must be one of the most dramatic technologies for polymer synthesis in the 1980s. Especially,… Expand
Peroxidase activity of in vitro-selected 2'-amino RNAs.
- N. Teramoto, H. Ichinari, N. Kawazoe, Y. Imanishi, Y. Ito
- Chemistry, Medicine
- Biotechnology and bioengineering
- 20 November 2001
Peroxidase activities of RNAs containing 2'-amino groups, which were selected as aptamers binding to N-methylmesoporphyrin IX, were investigated. Some clones promoted the oxidation reaction of… Expand
In vitro adaptation of a ligase ribozyme for activity under a low-pH condition.
- Y. Miyamoto, N. Teramoto, Y. Imanishi, Y. Ito
- Biology, Medicine
- Biotechnology and bioengineering
- 5 December 2001
A ligase ribozyme accelerating a ligation reaction with oligonucleotide under a low-pH condition was selected by in vitro adaptation. A ribozyme active at pH 7 was randomly mutated, and the resultant… Expand
