Phthalate esters have been used extensively as plasticizers of synthetic polymers. Recent
studies have revealed that these esters induce atrophy of the testis, although its pathogenesis …

Although photoexcited TiO 2 has been known to initiate various chemical reactions, such as
the generation of reactive oxygen species, precise mechanism and chemical nature of the …

Reactive oxygen species (ROS) play important roles in the defense mechanism against
infection and in the pathogenesis of various diseases. Although chemical properties of ROS …

Nickel peroxide, readily obtainable by the treatment of nickel salts with sodium hypochlorite
in alkaline solution, was shown to be a useful oxidizing agent for several types of organic …

Serratia marcescens is an important opportunistic pathogen in hospitals, where quaternary
ammonium compounds are often used for disinfection. The aim of this study is to elucidate …

We previously reported that irradiation of titanium dioxide (TiO 2 ) in ethanol generates both
singlet oxygen ( 1 O 2 ) and superoxide anion (O 2 ·- ) as measured by EPR spectroscopy. …

We report direct electron spin resonance (ESR) evidence of extracellular free radical formation
during kainic acid-induced seizures obtained using in vivo brain microdialysis in freely …

… Since Nakagawa,Konaka, and Nakata1 previously found that nickel peroxide was a useful
oxidizing agent on the oxidation of alcohols, a lot of the reactions using nickel peroxide have …

Publisher Summary Titanium dioxide (TiO 2 ) and zinc oxide (ZnO) are photo-semiconducting
catalysts used in the oxidation of various organic compounds. Spin-trapping studies using …

Various radical-scavenging activities of thiamin and thiamin diphosphate (TDP) were found
in some in vitro experiments. Thiamin and TDP caused considerable suppressive effects on …
