Electromagnetic waves affect living organisms and it is of great interest for wide interaction of new sources with a diversity of frequencies and powers to life of people. In the last few years, many authors have proposed that the biological effect of electromagnetic fields in both the high-frequency and low-frequency ranges are connected with oxidative processes in tissues. Studying the change...

The release mechanism regulating SR Ca2+ homeostasis is significantly more sensitive than the uptake mechanisms. The exquisite sensitivity exhibited by ryanodine-sensitive Ca2+ channel complexes (i.e., ryanodine receptors, RyRs) to functional perturbation by chemically diverse sulfhydryl-modifying compounds can include phases of activation and inhibition that are dependent on the concentration ...

The transport of charge through the DNA base-pair stack offers a route to carry out redox chemistry at a distance. Here we describe characteristics of this chemistry that have been elucidated and how this chemistry may be utilized within the cell. The shallow distance dependence associated with these redox reactions permits DNA-mediated signaling over long molecular distances in the genome and ...

Thiol-based regulatory switches play central roles in cellular responses to oxidative stress, nitrosative stress, and changes in the overall thiol-disulfide redox balance. Protein sulfhydryls offer a great deal of flexibility in the different types of modification they can undergo and the range of chemical signals they can perceive. For example, recent work on OhrR and OxyR has clearly establis...

Reduction-oxidation (redox) reactions are an essential part of cell metabolism and represent a major fraction of all catabolic and anabolic reactions. Their dominant characteristic is that they generate and consume compounds with in part highly negative redox potential. Redox reactions occur at many sites in the cell, e.g. in membranes such as thylakoids, plastid envelope, and plasma membrane a...

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 recent penetration of renewable sources in the energy system caused a transformation of the needs of the distribution system and amplified the need of energy storage systems to properly balance the electricity grid. Among electrochemical energy storage devices, all vanadium flow batteries are those of the most promising technologies due to their high efficiency, long lifetime, reliability a...
