This review considers the recent investigations in scope of biodegradability synthetic polymers, spanning polyethylene (PE), polypropylene (PP), and their corresponding composites, with a focus on influence oxo-additives (mostly transition metal salts). The types mechanisms oxidation acceleration are discussed. Furthermore, both physicochemical biological stages degradation is evaluated (labora...

Introduction: Perchloroethylene (PCE) is one of the most well-known chlorinated organic compounds recently detected in aqueous environments. The presence of PCE in aquatic ecosystems has caused many health problems and environmental challenges. Therefore, its removal and treatment from aqueous environments are essential. Materials and Methods: The electro-Fenton (EF) process was carried out in...

Enzyme inhibition due to the reversible binding of reaction products is common and underlies the origins of negative feedback inhibition in many metabolic and signaling pathways. Product inhibition generates non-linearity in steady-state time courses of enzyme activity, which limits the utility of well-established enzymology approaches developed under the assumption of irreversible product rele...

Interaction of cGMP-dependent protein kinase with histones H2A, H2B, H3, and H4, or poly(L-arginine) resulted in changes in enzyme conformation such that inactivation of cGMP binding and activation of basal catalytic activity (assayed without cGMP) occurred. Total kinase activity as determined by phosphorylation of exogenous substrates subsequently decreased, but autophosphorylation of the enzy...
