Magnesium intake is inversely associated with the prevalence of tooth loss in Japanese pregnant women: the Osaka Maternal and Child Health Study
Tanaka K, Miyake Y, Sasaki S, Ohya Y, Miyamoto S, Matsunaga I, et al.
Magnes Res . 2007 Apr; 19(4):268-75. PMID: 17402295
There have only been a few studies on the role of mineral intake in tooth loss. We investigated the association between mineral intake and the prevalence of tooth loss in...

Fat and fish intake and asthma in Japanese women: baseline data from the Osaka Maternal and Child Health Study
Miyamoto S, Miyake Y, Sasaki S, Tanaka K, Ohya Y, Matsunaga I, et al.
Int J Tuberc Lung Dis . 2007 Jan; 11(1):103-9. PMID: 17217138
Objective: It remains controversial whether the intake of n-3 polyunsaturated fatty acids and fish is preventive against asthma. This cross-sectional study investigated the relationship between fat and fish intake and...

Relationship between active and passive smoking and total serum IgE levels in Japanese women: baseline data from the Osaka Maternal and Child Health Study
Miyake Y, Miyamoto S, Ohya Y, Sasaki S, Matsunaga I, Yoshida T, et al.
Int Arch Allergy Immunol . 2004 Oct; 135(3):221-8. PMID: 15467374
Background: Many studies have shown that cigarette smoking is associated with elevated concentrations of total serum IgE. Few studies, however, have examined total IgE in relation to passive smoking exposure,...

Site-directed mutagenesis of the putative distal helix of peroxygenase cytochrome P450
Matsunaga I, Ueda A, Sumimoto T, Ichihara K, Ayata M, Ogura H
Arch Biochem Biophys . 2001 Sep; 394(1):45-53. PMID: 11566026
CYP152A1 is an unusual, peroxygenase enzyme that catalyzes the beta- or alpha-hydroxylation of fatty acids by efficiently introducing an oxygen atom from H2O2 to the fatty acid. To clarify the...

Hemadsorption expressed by cloned H genes from subacute sclerosing panencephalitis (SSPE) viruses and their possible progenitor measles viruses isolated in Osaka, Japan
Furukawa K, Ayata M, Kimura M, Seto T, Matsunaga I, Murata R, et al.
Microbiol Immunol . 2001 Mar; 45(1):59-68. PMID: 11270608
Most subacute sclerosing panencephalitis (SSPE) viruses, including our Osaka-1, -2, and -3 strains isolated in Osaka, have shown negative hemadsorption (HAD) by African green monkey red blood cells. This property...

Unique heme environment at the putative distal region of hydrogen peroxide-dependent fatty acid alpha-hydroxylase from Sphingomonas paucimobilis (peroxygenase P450(SPalpha)
Imai Y, Matsunaga I, KUSUNOSE E, Ichihara K
J Biochem . 2000 Aug; 128(2):189-94. PMID: 10920253
Fatty acid alpha-hydroxylase from Sphingomonas paucimobilis is a hydrogen peroxide-dependent cytochrome P450 (P450) enzyme (P450(SPalpha)). In this study, heme-ligand exchange reactions of P450(SPalpha) were investigated using the optical spectroscopic method...

A lung model describing uptake of organic solvents and roles of mucosal blood flow and metabolism in the bronchioles
Kumagai S, Matsunaga I
Inhal Toxicol . 2000 Jul; 12(6):491-510. PMID: 10880141
A simple lung model (mucosal blood flow and metabolism model, MBM model) was developed to describe the uptake of organic solvents and investigate the role of mucosal blood flow and...

Fatty acid-specific, regiospecific, and stereospecific hydroxylation by cytochrome P450 (CYP152B1) from Sphingomonas paucimobilis: substrate structure required for alpha-hydroxylation
Matsunaga I, Sumimoto T, Ueda A, KUSUNOSE E, Ichihara K
Lipids . 2000 Jun; 35(4):365-71. PMID: 10858020
Fatty acid alpha-hydroxylase from Sphingomonas paucimobilis is an unusual cytochrome P450 enzyme that hydroxylates the alpha-carbon of fatty acids in the presence of H2O2. Herein, we describe our investigation concerning...

Cell surface expression of immature H glycoprotein in measles virus-infected cells
Ogura H, Matsunaga I, Takano Y, Ning X, Ayata M, Tanaka K, et al.
Virus Res . 2000 Mar; 66(2):187-96. PMID: 10725551
Two forms of hemagglutinin (H) protein, one with an apparent molecular mass of 78 kDa (78K H protein) and the other with that of 74 kDa (74K H protein), are...

Characterization of the ybdT gene product of Bacillus subtilis: novel fatty acid beta-hydroxylating cytochrome P450
Matsunaga I, Ueda A, Fujiwara N, Sumimoto T, Ichihara K
Lipids . 1999 Oct; 34(8):841-6. PMID: 10529095
We have characterized the gene encoding fatty acid alpha-hydroxylase, a cytochrome P450 (P450) enzyme, from Sphingomonas paucimobilis. A database homology search indicated that the deduced amino acid sequence of this...
