Nitric Oxide Scavenging by Environmental Particles and Engineered Nanoparticles: Size and Composition Dependency

Environmental Fate and Ecotoxicity of Engineered Nanoparticles

Nitric oxide scavenging modulates mitochondrial dysfunction induced by hypoxia/reoxygenation.

The objective of the present study was to delineate the role of excessive accumulation of mitochondrial nitrogen species contributing to oxidative stress induced by hypoxia/reoxygenation in isolated mitochondria. The present study shows that incubation of isolated rat heart mitochondria under hypoxic, but not anoxic conditions, followed by reoxygenation decreases the rate of mitochondrial oxyge...

Review Paper: Role of Nitric Oxide on Dopamine Release and Morphine-Dependency

The catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. Repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. Morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. Studies reported that mor...

Nitric oxide and the bioactivities

Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...

Lipid Peroxidation Inhibition, Superoxide Anion and Nitric Oxide Radical Scavenging Properties of Thymus daenensis and Anethum graveolens Essential Oils

Background: Safety and efficacy of the synthetic antioxidants used in the food industry are frequently questioned because such antioxidants are unstable and highly volatile, therefore, interest in finding naturally occurring antioxidants that have the potential to protect human beings from damage induced by oxidative stress has intensified. Objective: Bioactivities of Thymus daenensis and Ane...
