New CTI Correction Method for the Spaced-Row Charge Injection of the Suzaku X-Ray Imaging Spectrometer (2008)

Uchiyama, Hideki, Ozawa, Midori, Matsumoto, Hironori, Tsuru, Takeshi Go, Koyama, Katsuji, Kimura, Masashi, ...

The charge transfer inefficiency (CTI) of the X-ray CCDs on board the Suzaku satellite (X-ray Imaging Spectrometers; XIS) has increased since the launch due to radiation damage, and the energy...

Energy-Scale Calibration of the Suzaku X-Ray Imaging Spectrometer Using the Checker Flag Charge Injection Technique in Orbit (2008)

Ozawa, Midori, Uchiyama, Hideki, Matsumoto, Hironori, Nakajima, Hiroshi, Koyama, Katsuji, Tsuru, Takeshi Go, ...

The X-ray Imaging Spectrometer (XIS) on board the Suzaku satellite is an X-ray CCD camera system that has superior performance such as a low background, high quantum efficiency, and good energy...

Discovery of Extended X-Ray emission from the unidentified TeV source HESS J1614-518 using the Suzaku Satellite (2007)

Matsumoto, Hironori, Uchiyama, Hideki, Sawada, Makoto, Tsuru, Takeshi G., Koyama, Katsuji, Katagiri, Hideaki, ...

We report the Suzaku results of HESS J1614-518, which is the brightest extended TeV gamma-ray source discovered in the Galactic plane survey conducted using the H.E.S.S. telescope. We discovered...

Suzaku Observations of HESS J1616-508: Evidence for a Dark Particle Accelerator (2006)

Matsumoto, Hironori, Ueno, Masaru, Bamba, Aya, Hyodo, Yoshiaki, Mori, Hideyuki, Uchiyama, Hideki, ...

We observed the bright unidentified TeV gamma-ray source HESS J1616-508 with the X-ray Imaging Spectrometers onboard the Suzaku satellite. No X-ray counterpart was found to a limiting flux of 3.1e-13...

Contribution of Chemical 6-O-Sulfation of the Aminodeoxyhexose Residues in Whale Heparin with High Affinity for Antithrombin III to Its Anticoagulant Properties (1990)

Uchiyama, Hideki, Metori, Atsuko, Ogamo, Akira, Nagasawa, Kinzo

The tributylammonium salt of whale (Balaenoptera borealis L.) intestinal heparin with high affinity for antithrombin III, whose degrees of sulfate-substitution in D-glucosamine and L-iduronic acid...

Generation of Affinity for Antithrombin III by Supplemental Sulfation of Heparin Species with Low Affinity for the Protein (1990)

Ogamo, Akira, Metori, Atsuko, Uchiyama, Hideki, Nagasawa, Kinzo

The tributylammonium salt of a porcine heparin subtraction with low affinity for antithrombin III (Mr 7,500–18,000; anti-clotting activity, 7 USP units/mg), having degrees of sulfate...

A Method to Determine the Affinity of Heparin to Thrombin and Antithrorabin III on Equilibrium Gel Permeation Chromatography (1984)

OSHIMA, Genichiro, UCHIYAMA, Hideki, NAGASAWA, Kinzo

Equilibrium gel permeation chromatography was employed to determine the ability of heparin to form complexes with thrombin and antithrombin III. In the eluate from a Sephacryl S-200 column, heparin...

Anticoagulant Properties of Heparin Preparations from Different Animal Sources with Equivalent High Affinity for Antithrombin III (1984)

NAGASAWA, Kinzo, UCHIYAMA, Hideki

Three kinds of heparins from different animal sources—hog-intestinal heparin (167 USP units/mg), bovine-lung heparin (149 USP units/mg) and whale-intestinal heparin (Balaenoptera borealis...

Preparation of Biologically Active Fluorescent Heparin Composed of Fluorescein-Labeled Species and Its Behavior to Antithrombin III (1981)

UCHIYAMA, Hideki, NAGASAWA, Kinzo

A hog-mucosal heparin purified gel-chromatographically (total sulfate, 2.20; N-sulfate, 0.82; N-acetyl, 0.15 (mol/mol HexN); activity, 184 USP units/mg) was partially N-desulfated to give a...
