background: prolonged use of cyclosporine a for prevention of allograft rejection is associated with nephrotoxicity development. naringenin and olive oil are beneficial dietary antioxidants with potential renoprotective properties. this study aimed to evaluate the therapeutic effect of naringenin and olive oil in alleviating cyclosporine induced nephrotoxicity in rats by the assessment of renal...

Building wetlands in small arable streams is a popular supplement to best management practice on arable fields. Particle bound phosphorus settles in the small constructed wetlands (CWs), receiving agricultural diffuse pollution. The sorption behavior of phosphorus is, however, redox-sensitive, and bound phosphorus may be remobilized in periods with low redox potential. This paper investigates c...

Open circuit potential (OCP) measurements can be very sensitive to small changes in the electrode environment and may allow detection of electron transfer events involving few, and maybe single, electrons. Factors affecting the overall sensitivity of OCP measurements were investigated to achieve the highest sensitivity. The OCP of platinum ultramicroelectrodes (UMEs) was determined in solutions...

There was an error published in J. Cell Sci. 127, 4531-4541. Incorrect concentrations of the components used to establish the oxidising redox potential were given in the ‘Redox buffering’ section of the Materials and Methods. The correct sentence should read: An oxidising redox potential of −180 mV was established with 0.95 mM GSH and 0.1 mM GSSG. The authors apologise to the readers for any co...

Here, we report the impact of redox potential on isolated cardiac ryanodine receptor (RyR2) channel activity and its response to physiological changes in luminal [Ca(2+)]. Basal leak from the sarcoplasmic reticulum is required for normal Ca(2+) handling, but excess diastolic Ca(2+) leak attributed to oxidative stress is thought to lower the threshold of RyR2 for spontaneous sarcoplasmic reticul...

Cytochrome c(550) (cyt c(550)) is a component of photosystem II (PSII) from cyanobacteria, red algae, and some other eukaryotic algae. Its physiological role remains unclear. In the present work, measurements of the midpoint redox potential (E(m)) were performed using intact PSII core complexes preparations from a histidine-tagged PSII mutant strain of the thermophilic cyanobacterium Thermosyne...
