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...

Redox signals have emerged as important regulators of cellular physiology and pathology. The advent of redox imaging in vertebrate systems now provides the opportunity to dynamically visualize redox signaling during development and disease. In this review, we summarize recent advances in the generation of genetically encoded redox indicators (GERIs), introduce new redox imaging strategies, and ...

The conditional formal potential, E°′of Methyldopa has been studied by cyclic voltammetry at the surface of activated glassy carbon electrode (AGCE) as the working electrode in different pH phosphate buffered solutions. The experimental Standard redox potential, E°′, of Methyldopa is obtained to be 0.72 mV versus SHE (Standard Hydrogen Electrode). E°′ values have also been calculated with the a...

Changes in intracellular redox couples and redox reactive molecules have been implicated in the regulation of a variety of cellular processes, including cell proliferation and growth arrest by contact inhibition. However, the magnitude, direction, and temporal relationship of redox changes to cellular responses are incompletely defined. The present work sought to characterize redox and metaboli...

Redox state is a term used widely in the research field of free radicals and oxidative stress. Unfortunately, it is used as a general term referring to relative changes that are not well defined or quantitated. In this review we provide a definition for the redox environment of biological fluids, cell organelles, cells, or tissue. We illustrate how the reduction potential of various redox coupl...

Oxidative stress in a biological system is often defined as a redox imbalance within cells or groups of cells within an organism. Reductive-oxidative (redox) imbalances in cellular systems have been implicated in several diseases, such as cancer. To better understand the redox environment within cellular systems, it is important to be able to characterize the relationship between the intensity ...

Recently significant advances have been made to understand the pathophysiological mechanisms of neurodegenerative disorders to provide real therapeutic benefits. There is evidence that persistent inflammation and oxidative stress are the crucial factors of ongoing cell damage in neurodegenerative complex etiology. The variety of reactive oxygen and nitrogen species are the cause of both axonal ...

SIGNIFICANCE Environmental and endogenous reactive species such as reactive oxygen species (ROS), reactive nitrogen species (RNS), and other electrophiles are not only known to exert toxic effects on organisms, but are also emerging as molecules that mediate cell signaling responses. However, the mechanisms underlying this cellular redox signaling by reactive species remains largely uncharacter...

Wet soil microcosms were established to determine effects of organic matter and nitrate additions on microbial respiration and redox potentials. Organic matter (1%) and nitrate (100 ppm and 200 ppm) treatments were applied in factorial combination. Soil pH, redox potential, and CO2 emissions were measured. Data were analyzed by ANOVA for repeated measures and separately by sampling day. Additio...
