Nitrosative stress under microaerobic conditions triggers inositol metabolism in Pseudomonas extremaustralis. [PDF]

PLoS ONE
Bacteria are exposed to reactive oxygen and nitrogen species that provoke oxidative and nitrosative stress which can lead to macromolecule damage.

Nitrosative Stress in Retinal Pathologies: Review [PDF]

Antioxidants, 2019
Nitric oxide (NO) is a gas molecule with diverse physiological and cellular functions. In the eye, NO is used to maintain normal visual function as it is involved in photoreceptor light transduction.

Significance of nitrosative stress and glycoxidation products in the diagnosis of COVID-19 [PDF]

Scientific Reports
Nitrosative stress promotes protein glycoxidation, and both processes can occur during an infection with the SARS-CoV-2 virus. Therefore, the aim of this study was to assess selected nitrosative stress parameters and protein glycoxidation products in ...

Assessment of oxidative/nitrosative stress and raftlin in vitiligo

Indian Journal of Dermatology, 2022
Background: Vitiligo is a chronic skin disease characterized by white macules on the skin due to loss of melanocytes. Although there are many theories about the etiopathogenesis of the disease, oxidative stress is identified as an important determinant ...

Identification and Functional Analysis of GTP Cyclohydrolase II in Candida glabrata in Response to Nitrosative Stress

Frontiers in Microbiology, 2022
Reactive nitrogen species (RNS) are signal molecules involved in various biological events; however, excess levels of RNS cause nitrosative stress, leading to cell death and/or cellular dysfunction.

FeTPPS, a Peroxynitrite Decomposition Catalyst, Ameliorates Nitrosative Stress in Human Spermatozoa

Antioxidants, 2023
Excessive levels of reactive nitrogen species (RNS), such as peroxynitrite, promote nitrosative stress, which is an important cause of impaired sperm function.

Nitrosative stress in plants [PDF]

FEBS Letters, 2007
Nitrosative stress has become a usual term in the physiology of nitric oxide in mammalian systems. However, in plants there is much less information on this type of stress. Using olive leaves as experimental model, the effect of salinity on the potential induction of nitrosative stress was studied.

Enzymatic and Non-Enzymatic Response during Nitrosative Stress in Escherichia coli

Postępy Mikrobiologii, 2022
Nitrosative stress is an adverse physiological condition mediated by an excessive level of reactive nitrogen species (RNS). RNS react with the different macromolecules in vivo and result in the inactivation of these molecules.

Fundamental Mechanisms of the Cell Death Caused by Nitrosative Stress

Frontiers in Cell and Developmental Biology, 2021
Nitrosative stress, as an important oxygen metabolism disorder, has been shown to be closely associated with cardiovascular diseases, such as myocardial ischemia/reperfusion injury, aortic aneurysm, heart failure, hypertension, and atherosclerosis ...

Arginase2 mediates contrast-induced acute kidney injury via facilitating nitrosative stress in tubular cells

Redox Biology, 2023
Contrast-induced acute kidney injury(CI-AKI) is the third cause of AKI. Although tubular injury has been regarded as an important pathophysiology of CI-AKI, the underlying mechanism remains elusive.
