Regulation of Reactive Oxygen Species and Antioxidant Defense in Plants under Salinity
International Journal of Molecular Sciences, 2021 The generation of oxygen radicals and their derivatives, known as reactive oxygen species, (ROS) is a part of the signaling process in higher plants at lower concentrations, but at higher concentrations, those ROS cause oxidative stress. Salinity-induced

Manipulation of environmental oxygen modifies reactive oxygen and nitrogen species generation during myogenesis [PDF]
, 2016 Regulated changes in reactive oxygen and nitrogen species (RONS) activities are important in maintaining the normal sequence and development of myogenesis. Both excessive formation and reduction in RONS have been shown to affect muscle differentiation in

Granzymes in health and diseases: the good, the bad and the ugly
Frontiers in ImmunologyGranzymes are a family of serine proteases, composed of five human members: GA, B, H, M and K. They were first discovered in the 1980s within cytotoxic granules released during NK cell- and T cell-mediated killing.

Formation and Stabilization of Ground and Excited State Singlet O$_2$ upon Recombination of $^3$P Oxygen on Amorphous Solid Water [PDF]
J. Phys. Chem. Lett. 2020, 11, 6, 2171-2176, 2019 The recombination dynamics of $^3$P oxygen atoms on cold amorphous solid water to form triplet and singlet molecular oxygen (O$_2$) is followed under conditions representative for cold clouds. It is found that both, formation of ground state ($X ^3 \Sigma_{g}^{-}$) O$_2$ and molecular oxygen in the two lowest singlet states ($a ^1\Delta_g$ and $b ^1 ...

Reactive oxygen species, abiotic stress and stress combination.
The Plant Journal, 2017 Reactive oxygen species (ROS) play a key role in the acclimation process of plants to abiotic stress. They primarily function as signal transduction molecules that regulate different pathways during plant acclimation to stress, but are also toxic ...

Reactive Oxygen Species-Induced Lipid Peroxidation in Apoptosis, Autophagy, and Ferroptosis
Oxidative Medicine and Cellular Longevity, 2019 Reactive oxygen species- (ROS-) induced lipid peroxidation plays a critical role in cell death including apoptosis, autophagy, and ferroptosis. This fundamental and conserved mechanism is based on an excess of ROS which attacks biomembranes, propagates ...

Selective generation of reactive oxygen species in plasma activated water using CO2 plasma [PDF]
arXiv, 2022 In the present work, a process of a selective generation of reactive oxygen species (ROS) such as H2O2 and dissolved O3 in plasma-activated water (PAW) is discussed. For selective ROS generation, pure CO2 was used as a plasma-forming gas. The gases species present in plasma and properties of PAW are compared in details when CO2 and air are used as ...

Non-lethal exposure to H2O2 boosts bacterial survival and evolvability against oxidative stress [PDF]
, 2020 Unicellular organisms have the prevalent challenge to survive under oxidative stress of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). ROS are present as by-products of photosynthesis and aerobic respiration.

DFT Investigation of pH-Driven Oxygen Vacancy Formation-Annihilation in CeO2 [PDF]
arXiv, 2021 There is considerable interest in the pH-dependent switchable biocatalytic properties of cerium oxide nanoparticles (CeNPs) in biomedicine, where these materials exhibit beneficial antioxidant activity against reactive oxygen species at neutral and basic physiological pH but cytotoxic prooxidant activity at acidic pathological pH. Oxygen vacancies play
