We report on the discovery of fast-moving X-ray--emitting ejecta knots in the Galactic Oxygen-rich supernova remnant Puppis A from XMM-Newton observations. We find an X-ray knotty feature...
The Slow X-Ray Expansion of the Northwestern Rim of the Supernova Remnant RX J0852.0-4622 (2008)
Katsuda, S., Tsunemi, H., Mori, K.
The detection of radioactive decay line of 44Ti provides a unique evidence that the gamma-ray source is a young (< 1,000 yr) supernova remnant because of its short lifetime of about 90 yr. Only two...
Asymmetric Ejecta Distribution of the Cygnus Loop revealed with Suzaku (2008)
Katsuda, S., Tsunemi, H., Miyata, E., Mori, K., Namiki, M., Nemes, N., ...
We observed a linearly sliced area of the Cygnus Loop from the north-east to the south-west with Suzaku in seven pointings. After dividing the entire fields of view (FOV) into 119 cells, we extracted...
Katsuda, S., Tsunemi, H., Uchida, H., Miyata, E., Nemes, N., Miller, E. D., ...
We present the results of a spatially resolved spectral analysis from four Suzaku observations covering the northeastern rim of the Cygnus Loop. A two-kT_e non-ionization equilibrium (NEI) model...
Performance of the Charge Injection Capability of Suzaku XIS (2007)
Nakajima, H., Yamaguchi, H., Matsumoto, H., Tsuru, T. G., Koyama, K., Tsunemi, H., ...
A charge injection technique is applied to the X-ray CCD camera, XIS (X-ray Imaging Spectrometer) onboard Suzaku. The charge transfer inefficiency (CTI) in each CCD column (vertical transfer channel)...
Ishisaki, Y., Maeda, Y., Fujimoto, R., Ozaki, M., Ebisawa, K., Takahashi, T., ...
We have developed a framework for the Monte-Carlo simulation of the X-Ray Telescopes (XRT) and the X-ray Imaging Spectrometers (XIS) onboard Suzaku, mainly for the scientific analysis of spatially...
Spatially Resolved X-ray Spectroscopy of Vela Shrapnel A (2006)
We present the detailed X-ray spectroscopy of Vela shrapnel A with the XMM-Newton satellite. Vela shrapnel A is one of several protrusions identified as bullets from Vela supernova explosion. The...
Oxidative stress by glutathione depletion induces osteonecrosis in rats (2006)
Ichiseki, T., Ueda, Y., Katsuda, S., Kitamura, K., Kaneuji, A., Matsumoto, T.
Objective. We recently implicated in vivo oxidative stress in the development of osteonecrosis in a steroid-induced osteonecrosis model in the domestic rabbit. In the present experiment we devised a...
Ichiseki, T., Kaneuji, A., Katsuda, S., Ueda, Y., Sugimori, T., Matsumoto, T.
Objective. Using a rabbit model, we investigated the DNA oxidation injury occurring in bone following steroid administration and focused on the relation between DNA oxidation injury and...

Human giant cell tumor (GCT) consists of multinucleated giant cells and mononuclear stromal cells, and is characterized by frequent vascular invasion without distant metastases. To study the role of...
Katsuda, S., Boyd, H. C., Fligner, C., Ross, R., Gown, A. M.
There have been only limited immunocytochemical studies of the cell composition of the early lesions of human atherosclerosis, and none that incorporate a comprehensive panel of antibodies to various...
Katsuda, S., Coltrera, M. D., Ross, R., Gown, A. M.
The accumulation of smooth muscle cells is a major phenomenon associated with the pathogenesis of lesions of atherosclerosis. Smooth muscle cell proliferation in response to the release of growth...
Katsuda, S., Okada, Y., Okada, Y., Imai, K., Nakanishi, I.
Degradation of elastic fibers in the arterial walls is an important step in the development of atherosclerosis. To identify the enzyme(s) responsible for the elastinolysis, we have designed an ex...
