Evaluation of minimum desorption temperatures of thermal compressors in adsorption refrigeration cycles (2006)

Saha, BB, El-Sharkawy, II, Chakraborty, A, Koyama, S, Banker, ND, Dutta, P, ...

The purpose of this paper is to identify the minimum desorption temperatures required to operate thermally driven adsorption beds of a solid sorption refrigeration system. The method is based on the...

Black Carbon from Rice Residues as Soil Amendment and for Carbon Sequestration (2006)

Haefele, SM, Konboon, Y, Knoblauch, C, Koyama, S, Gummert, M, Ladha, JK

On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic...

Long-term geomagnetic changes observed n association with earthquake swarm activities in the Izu Peninsula, Japan (2001)

Oshiman, N., Sasai, Y., Honkura, Y., Ishikawa, Y., Koyama, S.

Anomalous crustal uplift has continued since 1976 in the Izu Peninsula, Japan. Earthquake swarms have also occurred intermittently off the coast of Ito since 1978. Observations of the total intensity...

Effects of polycations on pulmonary vascular permeability in conscious sheep.

Toyofuku, T, Koyama, S, Kobayashi, T, Kusama, S, Ueda, G

The role of charged sites on the permeability characteristics of the pulmonary microvascular barrier were investigated using chronically instrumented unanesthetized sheep. In one series of...

Axin, a negative regulator of the Wnt signaling pathway, forms a complex with GSK-3beta and beta-catenin and promotes GSK-3beta-dependent phosphorylation of beta-catenin.

Ikeda, S, Kishida, S, Yamamoto, H, Murai, H, Koyama, S, Kikuchi, A

Glycogen synthase kinase-3 (GSK-3) mediates epidermal growth factor, insulin and Wnt signals to various downstream events such as glycogen metabolism, gene expression, proliferation and...

Small G protein Ral and its downstream molecules regulate endocytosis of EGF and insulin receptors.

Nakashima, S, Morinaka, K, Koyama, S, Ikeda, M, Kishida, M, Okawa, K, ...

The involvement of Ral and its downstream molecules in receptor-mediated endocytosis was examined. Expression of either RalG23V or RalS28N, which are known to be constitutively active and...

Antiproteases modulate bronchial epithelial cell responses to endotoxin.

Koyama, S., Rennard, S. I., Claassen, L., Robbins, R. A.

Escherichia coli endotoxin (0.1 to 1000 micrograms/ml) stimulated the release of neutrophil chemotactic activity (P < 0.001) and induced bronchial epithelial cell (BEC) cytotoxicity assessed by...

A sensitive radioimmunoassay for alpha-interferon: circulating alpha-interferon-like substance in the plasma of healthy individuals and rheumatoid arthritis patients.

Shiozawa, S, Chihara, K, Shiozawa, K, Fujita, T, Ikegami, H, Koyama, S, ...

A radioimmunoassay for circulating alpha-interferon (IFN alpha) has been developed using lymphoblastoid IFN alpha. The assay was specific for IFN alpha, and did not cross-react with IFN beta, IFN...

Detection of complement C3 and factor B gene expression in normal colorectal mucosa, adenomas and carcinomas

Andoh, A, Fujiyama, Y, Sakumoto, H, Uchihara, H, Kimura, T, Koyama, S, ...

Local secretion of complement components in the human intestine has been previously reported. However, the cellular source has not been identified. In this study, we demonstrate complement C3 and...
