Influence of Controlling Plasma Gas Species and Temperature on Reactive Species and Bactericidal Effect of the Plasma

open access: yesApplied Sciences, 2021
In this study, plasma gas species and temperature were varied to evaluate the reactive species produced and the bactericidal effect of plasma. Nitrogen, carbon dioxide, oxygen, and argon were used as the gas species, and the gas temperature of each ...

Feed-derived volatile basic nitrogen increases reactive oxygen species production of blood leukocytes in lactating dairy cows. [PDF]

open access: yes, 2017
The present study investigated over 9 months the changes of fermentative quality of total mixed rations (TMR) containing grass silage (GS) as a major component, associated with changes in the volatile basic nitrogen (VBN) levels in an experimental dairy ...

Bioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species

open access: yesJournal of Clinical Biochemistry and Nutrition, 2009
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders.

Physiological and pathophysiological role of reactive oxygen species and reactive nitrogen species in the kidney [PDF]

open access: yesClinical and Experimental Pharmacology and Physiology, 2018
SummaryEnd‐stage renal disease is a leading cause of morbidity and mortality worldwide. The prevalence of the disease and the number of patients who receive renal replacement therapy are expected to increase in the next decade. Accumulating evidence suggests that chronic hypoxia in the tubulointerstitium represents the final common pathway to end‐stage

Reactive nitrogen and oxygen species in anticoagulated blood of healthy sheep

open access: yes, 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.

Reactive Oxygen and Nitrogen Species in Pathogenesis of Vascular Complications of Diabetes [PDF]

open access: yesDiabetes & Metabolism Journal, 2012
Macrovascular and microvascular diseases are currently the principal causes of morbidity and mortality in subjects with diabetes. Disorders of the physiological signaling functions of reactive oxygen species (superoxide and hydrogen peroxide) and ...

Nitrogen application alleviates salt stress by enhancing osmotic balance, ROS scavenging, and photosynthesis of rapeseed seedlings (Brassica napus)

open access: yesPlant Signaling & Behavior, 2022
Nitrogen application could alleviate salt stress on crops, but the specific physiological mechanism is still unclear. Therefore, in this study, a pot experiment was conducted to explore the effects of different application rates of nitrogen (0, 0.15, 0 ...
