Synthesis of Fine-Grained Polycrystalline Diamond Compact and Its Microstructure. (1998)

Akaishi, M., Ohsawa, T., Yamaoka, S.

Sintering of a fine-grained polycrystalline diamond compact with grains less than 1 micron in size was successfully carried out by making a laminate on a WC/Co powder compact under sintering...

Ceramic Coating Technique Using Laser Spray Process for Solid Oxide Fuel Cells. (1998)

Uchiyama, F., Tsukamoto, K., Kaga, Y., Okuo, T., Yamaoka, S.

A new ceramic coating technique using a CO2 laser has been developed to make high temperature solid oxide fuel cells. A high power density laser beam is passed near the substrate. Coating material is...

Synthesis of Translucent Sintered Cubic Boron Nitride. (1998)

Akaishi, M., Satoh, T., Ishii, M., Taniguchi, T., Yamaoka, S.

It is clear from previous reports that hexagonal boron nitride (hBN) transforms directly to cubic boron nitride (cBN) at high pressure and high temperature without the aid of catalysts. Furthermore,...

Oncogenic transformation by the tax gene of human T-cell leukemia virus type I in vitro.

Tanaka, A, Takahashi, C, Yamaoka, S, Nosaka, T, Maki, M, Hatanaka, M

Human T-cell leukemia virus type I (HTLV-I) is a causative agent of adult T-cell leukemia (ATL). To elucidate the role of HTLV-I in leukemogenesis, we examined the biological activity of a defective...

Determination of methylation specificity of sequence-specific DNA methyltransferases using matrix assisted laser desorption/ionization time-of-flight mass spectrometry.

Tamura, T, Araki, Y, Yamaoka, S, Inagaki, K, Tanaka, H

We describe here a sensitive and straightforward method for characterizing the methylation specificity of type II DNA methyltransferase (MTase) using matrix-assisted laser desorption/ionization...

Coexistence of nuclear DNA-encoded tRNAVal(AAC) and mitochondrial DNA-encoded tRNAVal(UAC) in mitochondria of a liverwort Marchantia polymorpha.

Akashi, K, Takenaka, M, Yamaoka, S, Suyama, Y, Fukuzawa, H, Ohyama, K

The liverwort Marchantia polymorpha mitochondrial DNA encodes almost all tRNAs required for mitochondrial translation except for the isoleucine (AUU, AUC) and threonine (ACA, ACG) codons, while the...

The human T-cell leukemia virus type I Tax protein induces apoptosis which is blocked by the Bcl-2 protein.

Yamada, T, Yamaoka, S, Goto, T, Nakai, M, Tsujimoto, Y, Hatanaka, M

The Tax protein of human T-cell leukemia virus type I activates transcription of cellular and viral genes and can immortalize primary T lymphocytes. We have previously reported that the Tax protein...

Constitutive activation of NF-kappa B is essential for transformation of rat fibroblasts by the human T-cell leukemia virus type I Tax protein.

Yamaoka, S, Inoue, H, Sakurai, M, Sugiyama, T, Hazama, M, Yamada, T, ...

Human T-cell leukemia virus type I (HTLV-I) encodes a 40 kDa trans-acting protein, Tax, that regulates transcription of both the proviral and cellular genes, and can transform rat fibroblasts. To...

Development of colonic neoplasia in p53 deficient mice with experimental colitis induced by dextran sulphate sodium

Fujii, S, Fujimori, T, Kawamata, H, Takeda, J, Kitajima, K, Omotehara, F, ...

Background: Several animal models for human ulcerative colitis (UC) associated neoplasia have been reported. However, most neoplasias developed in these models have morphological and genetic...
