Reactive Oxygen Species (ROS) Metabolism and Nitric Oxide (NO) Content in Roots and Shoots of Rice (Oryza sativa L.) Plants under Arsenic-Induced Stress

open access: yesAgronomy, 2020
Arsenic (As) is a highly toxic metalloid for all forms of life including plants. Rice is the main food source for different countries worldwide, although it can take up high amounts of As in comparison with other crops, showing toxic profiles such as ...

Impact of Nitric Oxide (NO) on the ROS Metabolism of Peroxisomes

open access: yesPlants, 2019
Nitric oxide (NO) is a gaseous free radical endogenously generated in plant cells. Peroxisomes are cell organelles characterized by an active metabolism of reactive oxygen species (ROS) and are also one of the main cellular sites of NO production in ...

Acute Effects of Photobiomodulation Therapy Combined with Static Magnetic Field in C2C12 Muscle Cells Exposed and Not Exposed to H2O2

open access: yesApplied Sciences
Photobiomodulation (PBM) has been applied in biomedical technology to improve cellular responses. Specifically in sports medicine, it is used to accelerate metabolic and structural repair and adaptation in skeletal muscle under stress overload. Currently,

Protein nitration: A connecting bridge between nitric oxide (NO) and plant stress

open access: yesPlant Stress, 2021
Nitric oxide (•NO) is a free radical which exerts a myriad of functions in the physiology of higher plants either under physiological and environmental stress conditions.

5-Aryl-2-(3,5-dialkyl-4-hydroxyphenyl)-4,4-dimethyl-4H-imidazole 3-Oxides and Their Redox Species: How Antioxidant Activity of 1-Hydroxy-2,5-dihydro-1H-imidazoles Correlates with the Stability of Hybrid Phenoxyl–Nitroxides

open access: yesMolecules, 2020
Cyclic nitrones of the imidazole series, containing a sterically hindered phenol group, are promising objects for studying antioxidant activity; on the other hand, they can form persistent hybrid phenoxyl–nitroxyl radicals (HPNs) upon oxidation.

“Alperujo” Compost Improves the Ascorbate (Vitamin C) Content in Pepper (Capsicum annuum L.) Fruits and Influences Their Oxidative Metabolism

open access: yesAgronomy, 2018
“Alperujo” compost was evaluated as an organic fertiliser for pepper growth under greenhouse conditions. Even though the total nitrogen applied was similar, plants only grown with composts experienced a development decline as compared to ...

Antioxidants and Carcinogenesis

open access: yesAnnals of Medicine, 1994
It is established beyond doubt that free radicals in tissues and cells can damage DNA, proteins, carbohydrates and lipids. These potentially deleterious reactions are at least partly controlled by antioxidants capable of scavenging free radicals. It is widely believed that a proper balance between free radicals and antioxidants is essential for the ...

Tannase enhances the anti-inflammatory effect of grape pomace in Caco-2 cells treated with IL-1β

open access: yesJournal of Functional Foods, 2017
Grape pomace (GP) is rich in polymeric polyphenolics and glycosides which have lower bioefficacy than monomeric and aglycone counterparts. The aim of this study was to determine whether tannin acyl hydrolase [tannase (TNS)] can improve the antioxidant ...

Differential responses to salt-induced oxidative stress in three phylogenetically related plant species: Arabidopsis thaliana (glycophyte), Thellungiella salsuginea and Cakile maritima (halophytes). Involvement of ROS and NO in the control of K+/Na+ homeostasis

open access: yesAIMS Biophysics, 2016
Salinity, which is usually associated with a nitro-oxidative stress component, is one of the major environmental factors limiting plant growth and development. Plants have thus developed specific ways of dealing with this problem.
