A 1-Gb AG-AND flash memory has been fabricated using 0.13-μm CMOS technology, resulting in a cell area of 0.104 μm2 and a chip area of 95.2 mm2. By applying constant-charge-injection programming...

Word Sense Disambiguation Using Pairwise Alignment (2003)

Koichi Yamashita, Keiichi Yoshida

In this paper, we proposed a new supervised word sense disambiguation (WSD) method based on a pairwise alignment technique, which is used generally to measure a similarity between DNA sequences.

Fructose 1,6-Bisphosphate Aldolase Is a Heparin-Binding Protein (1999)

Ta, Thanh-Van, Takano, Ryo, Kamei, Kaeko, Xu, Xin-Yan, Kariya, Yutaka, Yoshida, Keiichi, ...

Proteins with affinity to heparin under physiological conditions were isolated from bovine cerebral cortex. First, the extract of cerebral cortex was applied to a chondroitin polysulfate column under...

Importance of 2-O-Sulfate Groups of Uronate Residues in Heparin for Activation of FGF-1 and FGF-2 (1997)

Ishihara, Masayuki, Kariya, Yutaka, Kikuchi, Hiroshi, Minamisawa, Tosikazu, Yoshida, Keiichi

Complete drying of heparin with various concentrations of NaOH by lyophilization caused specific 2-O-desulfation to various degrees without detectable depolymerization or other chemical changes. In...

Importance of 6-0-Sulfate Groups of Glucosamine Residues in Heparin for Activation of FGF-1 and FGF-2 (1995)

Ishihara, Masayuki, Takano, Ryo, Kanda, Takashige, Hayashi, Kaeko, Hara, Saburo, Kikuchi, Hiroshi, ...

Treatment of the pyridinium salts of heparin with N-methyItrimethyIsilyl-trifluoro-acetamide (MTSTFA) in pyridine for 2 h at various temperatures caused specific 6-O-desul-fations from trisulfated...

Structural studies on the tri- and tetrasaccharides isolated from porcine intestinal heparin and characterization of heparinase/heparitinases using them as substrates (1994)

Yamada, Shuhei, Sakamoto, Kaori, Tsuda, Hiromi, Yoshida, Keiichi, Sugahara, Kazuyuki, Khoo, Kay-Hooi, ...

We prepared a series of oligosaccharides from porcine intestinal heparin after extensive digestion with a mixture of Flavobacterium heparinase as well as heparitinases I and II. Previously, we...

Patterns of uronosyl epimerization and 4-/6-0-sulphation in chondroitin/dermatan sulphate from decorin and biglycan of various bovine tissues (1994)

Cheng, Fang, Heinegård, Dick, Malmström, Anders, Schmidtchen, Artur, Yoshida, Keiichi, Fransson, Lars-AÅke

Dermatan sulphate is a co-polymer of two types of disac-charide repeats: D-glucuronate-N-acetylgalactosamine and L-iduronate-N-acetylgalactosamlne. The former can be O-sulphated at C-4 or C-6 of the...

One- and Two-Dimensional 1H-NMR Characterization of Two Series of Sulfated Disaccharides Prepared from Chondroitin Sulfate and Heparan Sulfate/Heparin by Bacterial Eliminase Digestion (1992)

Yamada, Shuhei, Yoshida, Keiichi, Sugiura, Makiko, Sugahara, Kazuyuki

The 1H-NMR spectra of eight unsaturated disaccharides obtained by bacterial eliminase digestion of chondroitin sulfate and of heparan sulfate/heparin were recorded in order to construct an NMR data...

A new method for sequence analysis of glycosaminoglycans from heavily substituted proteoglycans reveals non-random positioning of 4- and 6-O-sulphated N-acetylgalactosamine in aggrecan-derived chondroitin sulphate (1992)

Cheng, Fang, Yoshida, Keiichi, Heinegård, Dick, Fransson, Lars-Åke

We have developed a new procedure for the sequence analysis of glycosaminoglycans, which is particularly suitable for the analysis of chains from heavily substituted proteoglycans. The procedure has...
