Comparative analysis of the parameters of LPO, antioxidant defense (AOD), and the thiol/disulfide system was performed in fertile and infertile males of reproductive age carrying different genotypes of the glutathione system genes. Blood plasma, blood hemolysate, and ejaculate served as specimens for biochemical studies. A decrease in glutathione S-transferase activity was found in blood and ejaculate specimens from fertile and infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes. In infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes determining reduced glutathione S-transferase activity, a decrease in the concentration of low-molecular-weight cell antioxidant (reduced glutathione) and an increase in the concentration of secondary LPO products (TBA-reactive substances) were revealed. Identification of carriers the polymorphic GSTT1 and GSTM1 variants and analysis of activity of the thiol/disulfide system enzymes can be recommended for additional evaluation of the risk for reproductive dysfunction in men.

Coacervates have garnered significant attention as potential drug carriers. However, the instability resulting from their intrinsic membrane-free nature restricts the application of coacervates in drug delivery. Herein, the engineering of poly(ethylene glycol) nanoparticles (PEG NPs) is reported using coacervates composed of PEG and polyphenols as the templates, where PEG is subsequently cross-linked based on different chemistries (e.

Thiol/disulfide-based redox regulation is a key mechanism for modulating protein functions in response to changes in cellular redox status. Two thioredoxin (Trx)-like proteins [atypical Cys His-rich Trx (ACHT) and Trx-like2 (TrxL2)] have been identified as crucial for oxidizing and deactivating several chloroplast enzymes during light-to-dark transitions; however, their roles remain to be fully understood. In this study, we investigated the functions of Trx-like proteins in seed development.

Glutathione is the major thiol-based antioxidant in a wide variety of biological systems, ranging from bacteria to eukaryotes. As a redox couple, consisting of reduced glutathione (GSH) and its oxidized form, glutathione disulfide (GSSG), it is crucial for the maintenance of the cellular redox balance. Glutathione transport out of and into cellular compartments and the extracellular space is a determinant of the thiol-disulfide redox state of the organelles and bodily fluids in question, but is currently not well understood.

Within the context of circular economy and industrial ecology, adsorption offers an effective manner for recycling resources from wastewater, but controllable desorption remains a challenge. Inspired by metal-thiol binding and reversible thiol-disulfide redox transformation in biological systems, this study reports the development of a reversible adsorption/desorption (RAD) system for controllable recovery of copper based on electrochemically switchable sulfurized polyacrylonitrile (SPAN). Density functional theory calculations offered theoretical prediction for the formation of S-Cu bonds and reversible weak interaction between S-S bonds and Cu.
