Reactive nitrogen and oxygen species in anticoagulated blood of healthy sheep [PDF]
, 2013 Background : Little or no study has been done to compare the indices of ‘nitrosative’ and ‘oxidative’ stresses, especially in terms of correlation and the possible differential effects of the chelating agents.

Assessing the efficiency of reactive oxygen species colorimetric sensors for use in environmentally & biologically relevant samples [PDF]
, 2020 Neal, Sharon L.A longstanding interest in reactive oxygen species (ROS) stems from their role in many environmental, biological, clinical, and industrial processes.

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Disease Progression Mediated by Egr-1 Associated Signaling in Response to Oxidative Stress [PDF]
, 2012 When cellular reducing enzymes fail to shield the cell from increased amounts of reactive oxygen species (ROS), oxidative stress arises. The redox state is misbalanced, DNA and proteins are damaged and cellular transcription networks are activated.

Reactive oxygen species and sperm cells
Reproductive Biology and Endocrinology, 2004 There is a dynamic interplay between pro- and anti-oxidant substances in human ejaculate. Excessive reactive oxygen species (ROS) generation can overwhelm protective mechanism and initiate changes in lipid and/or protein layers of sperm plasma membranes.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]
, 2008 The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.

Mitochondrial complex II and reactive oxygen species in disease and therapy [PDF]
, 2020 Increasing evidence points to the respiratory Complex II (CII) as a source and modulator of reactive oxygen species (ROS). Both functional loss of CII as well as its pharmacological inhibition can lead to ROS generation in cells, with a relevant impact ...

Antimicrobial Actions of Reactive Oxygen Species
mBio, 2011 Everything should be as simple as it can be, but not simpler.—Attributed to Albert Einstein (1) IMPORTANCE Reactive oxygen species (ROS) are produced by host phagocytes and exert antimicrobial actions against a broad range of pathogens.
