MATSUBARA, T, ANWAR, R, FUJIWARA, M, ICHIYAMA, T, FURUKAWA, S

Kawasaki disease (KD) is an acute febrile illness of early childhood caused by vasculitis. Whether or not peripheral blood T cells are activated in acute KD remains uncertain, as some reports have...

Decreased interferon-gamma (IFN-γ)-producing T cells in patients with acute Kawasaki disease

Matsubara, T, Katayama, K, Matsuoka, T, Fujiwara, M, Koga, M, Furukawa, S

Kawasaki disease (KD) is an acute febrile illness of early childhood, in which the activation of monocytes/macrophages plays a central role in the development of vasculitis during the acute stage of...

CD14+CD16+ monocyte subpopulation in Kawasaki disease

Katayama, K, Matsubara, T, Fujiwara, M, Koga, M, Furukawa, S

Kawasaki disease (KD) is an acute febrile illness caused by vasculitis, occurring in early childhood. We have demonstrated that the activation of monocytes/macrophages plays a central role during...

Gamma-aminobutyric acid receptor on vascular smooth muscle of dog cerebral arteries.

Fujiwara, M, Muramatsu, I

Gamma-aminobutyric acid (GABA) had a relaxant effect on dog cerebral arteries which was blocked only by picrotoxin, a known antagonist of GABA receptors. Other agents, adrenoceptor and ganglion...

GABAA-receptor-mediated inhibition of the delayed increase in intragastric pressure to stimulation of vagal afferent fibres in cats.

Okamoto, T., Kurahashi, K., Fujiwara, M., Oikawa, H.

1. The possible involvement of gamma-aminobutyric acidA (GABAA)- and GABAB-receptors in the inhibitory effects of GABA on the delayed increase in intragastric pressure of the stomach to stimulation...

Effects of naloxone and opioid agonists on gastric excitatory responses to stimulation of the vagus nerve in cats.

Okamoto, T., Kurahashi, K., Fujiwara, M.

1. An investigation was made into the contribution of endogenous opioids to the initial and delayed excitatory response of the stomach induced by stimulation of the vagal trunk in cats. 2. Naloxone...

Regional differences of reactivity to stimulants in the dog portal tree.

Fujii, K., Fujiwara, M., Kumada, K., Kurahashi, K., Usui, H.

We studied the regional differences both of reactivity to various stimulants and of neurogenic responses elicited by transmural stimulation in the longitudinal and circular muscles of the truncal...

Four-wave mixing signals from β-carotene and its n = 15 homologue

Sugisaki, M., Fujiwara, M., Yanagi, K., Cogdell, R.J., Hashimoto, H.

Abstract The third-order nonlinear optical responses of β-carotene and its homologue having a conjugation-double bond n = 15 have been investigated using sub-20 fs ultra-short optical pulses in...

Immunohistochemical detection of major histocompatibility complex antigens and quantitative analysis of tumour-infiltrating mononuclear cells in renal cell cancer.

Tomita, Y., Nishiyama, T., Fujiwara, M., Sato, S.

In order to investigate the anti-tumour immune responsiveness of patients with renal cell cancer (RCC), we examined 30 such patients for the degree of expression of major histocompatibility complex...

Molecular basis for sensitivity and acquired resistance to gefitinib in HER2-overexpressing human gastric cancer cell lines derived from liver metastasis

Yokoyama, H, Ikehara, Y, Kodera, Y, Ikehara, S, Yatabe, Y, Mochizuki, Y, ...

Gastric cancer metastasised to the liver was found to overexpress HER2 at a significantly higher incidence than primary gastric cancers. The purpose of the present study was to investigate the...

Genetic instability in lung cancer: concurrent analysis of chromosomal, mini- and microsatellite instability and loss of heterozygosity

Ninomiya, H, Nomura, K, Satoh, Y, Okumura, S, Nakagawa, K, Fujiwara, M, ...

To investigate what kind of genetic instability plays important roles in lung carcinogenesis, we analyzed micro- and minisatellite instability, loss of heterozygosity (LOH) and chromosome instability...

Plasminogen activator inhibitor-1 as a potential marker for the malignancy of colorectal cancer

Sakakibara, T, Hibi, K, Koike, M, Fujiwara, M, Kodera, Y, Ito, K, ...

To test the hypothesis that plasminogen activator inhibitor-1 (PAI-1) may serve as a candidate marker for the malignancy of colorectal cancer (CRC), we performed a quantitative RT–PCR for PAI-1...
