Patients with chronic kidney disease (CKD) experience imbalance between oxygen reactive species (ROS) production and antioxidant defenses leading to cell and tissue damage. However, it remains unclear at which stage of renal insufficiency the redox imbalance becomes more profound. The aim of this systematic review was to provide an update on recent advances in our understanding of how the redox...

Mammalian cells do not survive in the absence of redox reactions; oxidation and reduction predominate in the swamp of metabolic biochemical reactions inside the cell. In a situation which is less stoichiometric, subtle alterations of the redox status in the intracellular environment also have significant impacts on cell biology. Changes in the intracellular redox status can be assessed by quant...

Redox-reactions are playing a significant role in regulation of homeostasis of organism. Disorder of the redox-status is related with the onset and/or propagation of oxidative diseases such as lifestyle-related diseases, including cancers and cardiac diseases, etc. In vivo imaging of redox-status is thereby important in the analysis of mechanisms of oxidative diseases and developments of new me...

Anaerobes can obtain the entire cell's ATP by glycolysis and remove resulting reducing power by fermentation. There is a delicate balance in redox status to obtain a maximal growth of these cells, and the conditions to change redox fluxes can induce kinds of changes in metabolism. The fundamental knowledge on sensing redox status and coupling redox signals with fermentation pathways is essentia...

Intracellular redox status plays a critical role in cell function, such as proliferation. Oxidative stress, which elicits redox imbalance, also affects cell growth. Therefore, it is often difficult to distinguish the effects of redox imbalance from those of oxidative stress. The objective of this study was to determine the role of redox imbalance independent of reactive oxygen species (ROS) pro...

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...

In this study the acute toxic effects of aluminum (Al) on mice have been investigated, including the interactions of Al and selenium (Se). Focus was put on the systemic effects of (co)exposure to Al and Se as a reflection of the redox status in the liver, kidney and brain. Short-term exposure (16 h) to Al resulted in an increase in the systemic inflammation parameters IL-6 and PAI-1, whereas se...

Embedded within the meristem of all Angiosperm roots is a population of slowly dividing cells designated the quiescent center (QC). In maize roots the QC can constitute upwards of 800-1200 cells, most of which spend an extended period of time (180-200 hours) in the G(1) phase of the cell cycle. How the QC forms and is maintained is not known. Here we report that cells of the QC are characterize...

Free radicals, particularly reactive oxygen species (ROS), are involved in various pathologies, injuries related to radiation, ischemia-reperfusion or ageing. Unfortunately, it is virtually impossible to directly detect free radicals in vivo, but the redox status of the whole organism or particular organ can be studied in vivo by using magnetic resonance techniques (EPR and MRI) and paramagneti...
