Ion distribution around a charged rod in one and two component solvents: Preferential solvation and first order ionization phase transition (2009)

Okamoto, Ryuichi, Onuki, Akira

In one and two component solvents, we calculate the counterion distribution around a charged rod treating the degree of ionization $\alpha$ as an annealed variable dependent on its local environment....

Solvation and Dissociation in Weakly Ionized Polyelectrolytes (2009)

Onuki, Akira, Okamoto, Ryuichi

We present a Ginzburg-Landau theory of inhomogeneous polyelectrolytes with a polar solvent. First, we take into account the molecular (solvation) interaction among the ions, the charged monomers, the...

Inducible expression of microRNA-194 is regulated by HNF-1{alpha} during intestinal epithelial cell differentiation (2008)

Hino, Kimihiro, Tsuchiya, Kiichiro, Fukao, Taro, Kiga, Kotaro, Okamoto, Ryuichi, Kanai, Takanori, ...

Maintenance of the intestinal epithelium is based on well-balanced molecular mechanisms that confer the stable and continuous supply of specialized epithelial cell lineages from multipotent...

Interferon Regulatory Factor 1 (IRF-1) and IRF-2 Distinctively Up-Regulate Gene Expression and Production of Interleukin-7 in Human Intestinal Epithelial Cells

Oshima, Shigeru, Nakamura, Tetsuya, Namiki, Shin, Okada, Eriko, Tsuchiya, Kiichiro, Okamoto, Ryuichi, ...

Intestinal epithelial cell-derived interleukin (IL)-7 functions as a pleiotropic and nonredundant cytokine in the human intestinal mucosa; however, the molecular basis of its production has remained...
