Autor: Shin-ichi Ozaki, Kei Shimoda, Naoki Nagatani, Hiroki Hamada, Naoji Kubota, Daisuke Uesugi

Publikováno v: Bioscience, Biotechnology, and Biochemistry. 81:226-230

The stilbene compound resveratrol was glycosylated to give its 4′-O-β-D-glucoside as the major product in addition to its 3-O-β-D-glucoside by a plant glucosyltransferase from Phytolacca americana expressed in recombinant Escherichia coli. This e

Rapid sensing of antioxidant capacity based on electrochemiluminescence induced by electrochemically generated reactive oxygen species

Autor: Akiko Araki, Eiichi Tamiya, Yutaka Ogidou, Hiromi Ushijima, Masato Saito, Yuki Inoue, Naoki Nagatani, Yasuhiro Sakurai, Gen Hattori

Publikováno v: Electrochimica Acta. 222:580-586

A simple and rapid electrochemiluminescence (ECL) method for the measurement of antioxidant capacity using a portable ECL device with a screen-printed electrode is described. The ECL method is based on the luminous reaction of reactive oxygen species

Autor: Aki Takahashi, Shigeru Uchiyama, Yuya Kato, Teruko Yuhi, Hiromi Ushijima, Makoto Takezaki, Toshihiro Tominaga, Yoshiko Moriyama, Kunio Takeda, Toshiro Miyahara and Naoki Nagatani

Publikováno v: Science and Technology of Advanced Materials, Vol 10, Iss 3, p 034604 (2009)

The concentration of salivary secretory immunoglobulin A (sIgA) is a well-known stress marker for humans. The concentration of salivary sIgA in dogs has also been reported as a useful stress marker. In addition, salivary sIgA in dogs has been used to

Electrochemical Monitoring of Antioxidant Capacity in Food

Autor: Hiromi Ushijima, Naoki Nagatani

Publikováno v: Food Biosensors ISBN: 9781782623618

A number of methods have been developed for measuring the capacity and efficacy of antioxidants, but there is no simple and universal measurement method. In this chapter, the electrochemical monitoring of antioxidant capacity is introduced. The antio

Electrochemical detection of specific DNA and respiratory activity of Escherichia coli

Autor: Naoki Nagatani, Keiichiro Yamanaka, Tomohiko Ikeuchi, Eiichi Tamiya, Masato Saito

Publikováno v: Electrochimica Acta. 82:132-136

We present two rapid and simplified detection methods for Escherichia coli involving the use of a hand-held potentiostat and a disposable screen-printed carbon electrode. E. coli is one of the indicator organisms used to access for food safety. Commo
