Early stages in the evolution of Izu–Bonin arc volcanism: new age, chemical, and isotopic constraints (2006)

Ishizuka, O., Kimura, J., Li, Y.B., Stern, R.J., Taylor, R.N., Ohara, Y., ...

A remarkable record of early arc volcanism in the Izu–Bonin–Mariana (IBM) arc is exposed in and around the Bonin Islands, an uplifted segment of the IBM forearc. New 40Ar/39Ar dating results...

Theiler's murine encephalomyelitis virus subgroup strain-specific infection in a murine macrophage-like cell line.

Obuchi, M, Ohara, Y, Takegami, T, Murayama, T, Takada, H, Iizuka, H

We compared infection of a murine macrophage-like cell line, J774-1, with two Theiler's murine encephalomyelitis virus subgroup strains. The GDVII strain, which is highly virulent and produces acute...

Human cytomegalovirus induces interleukin-8 production by a human monocytic cell line, THP-1, through acting concurrently on AP-1- and NF-kappaB-binding sites of the interleukin-8 gene.

Cytomegalovirus (CMV) infection induced interleukin-8 (IL-8) gene transcription in a human monocytic cell line, THP-1 cells, leading to IL-8 secretion. The functional analysis of the IL-8 gene...

Rare occurrence of the tetratype tetrads in Saccharomycodes ludwigii.

Yamazaki, T, Ohara, Y, Oshima, Y

Infectious cDNA clones of the DA strain of Theiler's murine encephalomyelitis virus.

Roos, R P, Stein, S, Ohara, Y, Fu, J L, Semler, B L

The DA strain and other members of the TO subgroup of Theiler's murine encephalomyelitis viruses cause a persistent demyelinating infection, whereas the GDVII strain and other GDVII subgroup strains...

Trypsin-sensitive neutralization site on VP1 of Theiler's murine encephalomyelitis viruses.

Ohara, Y, Senkowski, A, Fu, J L, Klaman, L, Goodall, J, Toth, M, ...

We generated Theiler's murine encephalomyelitis virus mutants resistant to several neutralizing monoclonal antibodies (MAbs) having their epitopes near a trypsin cleavage site of VP1. Neutralization...

Effects of fixation and varying target length on the sensitivity of polymerase chain reaction for detection of human T-cell leukemia virus type I proviral DNA in formalin-fixed tissue sections.

Honma, M, Ohara, Y, Murayama, H, Sako, K, Iwasaki, Y

In this study, the fixation condition most suitable for maintaining the sensitivity of the polymerase chain reaction (PCR) was investigated by using the alpha-tubulin gene sequence, and the PCR...

Microagglutination test for early and specific serodiagnosis of tularemia.

Sato, T, Fujita, H, Ohara, Y, Homma, M

A microagglutination test with safranin-stained Francisella tularensis antigen was compared with a conventional tube agglutination test for the serodiagnosis of tularemia. The microagglutination test...

N4-aminocytidine, a nucleoside analog that has an exceptionally high mutagenic activity.

Negishi, K, Harada, C, Ohara, Y, Oohara, K, Nitta, N, Hayatsu, H

The reaction of cytidine with hydrazine to give N4-aminocytidine was greatly promoted by addition of a less-than-stoichiometric amount of bisulfite, and the product was isolated in a good yield....

2-(p-Nitrophenyl)-2'-deoxyadenosine, a new type of mutagenic nucleoside.

Matsuda, A, Ohara, Y, Kakutani, T, Negishi, K, Wataya, Y, Hayatsu, H, ...

A crude preparation of 2-phenyladenosine was found to be mutagenic in the Ames Salmonella assay. In the purification of this preparation, it was revealed that 2-phenyladenosine itself was...

Hypercholesterolemia increases endothelial superoxide anion production.

Ohara, Y, Peterson, T E, Harrison, D G

Indirect evidence suggests accelerated degradation of endothelium-derived nitric oxide (ENDO) by superoxide anion (O2-) in hypercholesterolemic vessels (HV). To directly measure O2- production by...
