Endothelin-1 Enhances Superoxide and Prostaglandin E2 Production of Isolated Diabetic Glomeruli

open access: yesKaohsiung Journal of Medical Sciences, 2010
Endothelin-1 (ET-1) plays an important role in the pathogenic mechanism of diabetic nephropathy. However, the regulatory effects of ET-1 on superoxide and prostaglandin E2 (PGE2) in diabetic glomeruli are unclear.

Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]

open access: yes, 2007
Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

The influence of reactive oxygen species on local redox conditions in oxygenated natural waters

open access: yesFrontiers in Earth Science, 2016
Redox conditions in natural waters are a fundamental control on biogeochemical processes and ultimately many ecosystem functions. While the dioxygen/water redox couple controls redox thermodynamics in oxygenated aquatic environments on geological ...

Primary and secondary oxidative stress in Bacillus [PDF]

open access: yes, 2011
Coping with oxidative stress originating from oxidizing compounds or reactive oxygen species (ROS), associated with the exposure to agents that cause environmental stresses, is one of the prerequisites for an aerobic lifestyle of Bacillus spp. such as B.
