- Kataoka H, Matsuura E, Mitani K. Determination of cortisol in human saliva by automated in-tube solid-phase microextraction coupled with liquid chromatography-mass spectrometry. J Pharm Biomed Anal. 2007;44:160-5 pubmed..The recoveries of cortisol spiked into saliva samples were above 95%, and the relative standard deviations were below 6.0%. This method was used to analyze the changes in salivary cortisol level according to stress load. ..
- Kataoka H, Miyake M, Nishioka S, Matsumoto T, Saito K, Mitani K. Formation of protein adducts of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine in cooked foods. Mol Nutr Food Res. 2010;54:1039-48 pubmed publisher..PhIP-protein adducts were detected in several cooked meat and fish at ng/g food level as PhIP content. These results suggest that food-borne protein adducts of HCAs may influence human HCA exposure and carcinogenic risk. ..
