Dysfunctional mitochondrial processes contribute to energy perturbations in the brain and neuropsychiatric symptoms

Frontiers in Pharmacology, 2023
Mitochondria are complex endosymbionts that evolved from primordial purple nonsulfur bacteria. The incorporation of bacteria-derived mitochondria facilitates a more efficient and effective production of energy than what could be achieved based on ...

Seasonal cycles of ozone and oxidized nitrogen species in northeast Asia - 2 : A model analysis of the roles of chemistry and transport [PDF]

, 2002
[1] The dominant factors controlling the seasonal variations of ozone (O-3) and three major oxidized nitrogen species, peroxyacetyl nitrate (PAN), nitrogen oxides (NOx), and nitric acid (HNO3), in northeast Asia are investigated by using a three ...

2-Styrylchromones: Cytotoxicity and Modulation of Human Neutrophils’ Oxidative Burst

Pharmaceuticals, 2022
Neutrophils are polymorphonuclear leukocytes recruited to sites of acute inflammation, in response to pathogen invasion and tissue injury. The modulation of their activity, especially oxidative burst, may be important to control the inflammatory process.

Polyphenols of Camellia sinenesis decrease mortality, hepatic injury and generation of cytokines and reactive oxygen and nitrogen species after hemorrhage/resuscitation in rats [PDF]

, 2010
Background: Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are produced during hemorrhagic shock and resuscitation (H/R), which may contribute to multiple organ failure.

Bioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species

Journal 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.

Oxidative and nitrative modifications of enkephalins by reactive nitrogen species

, 2006
The interaction of Leucine-enkephalin (Leu-enkephalin) with reactive nitrogen species has been investigated. Reactive nitrogen species are capable of nitrating and oxidizing Leu-enkephalin.

Impacts of nitrogen deposition on vascular plants in Britain: an analysis of two national observation networks [PDF]

, 2011
Large areas of Great Britain currently have nitrogen (N) deposition at rates which exceed the thresholds above which there is risk of damage to sensitive components of the ecosystem (critical loads).

Antioxidants and skeletal muscle performance: ’Common knowledge’ vs. experimental evidence.

Frontiers in Physiology, 2012
Antioxidants are assumed to provide numerous benefits, including better health, a reduced rate of aging, and improved exercise performance. Specifically, antioxidants are commonly ‘prescribed’ by the media, supplement industry, and ‘fitness experts’ for

Reactive Nitrogen Species Reactivities with Nitrones: Theoretical and Experimental Studies [PDF]

Chemical Research in Toxicology, 2012
Reactive nitrogen species (RNS) such as nitrogen dioxide ((•)NO(2)), peroxynitrite (ONOO(-)), and nitrosoperoxycarbonate (ONOOCO(2)(-)) are among the most damaging species present in biological systems due to their ability to cause modification of key biomolecular systems through oxidation, nitrosylation, and nitration.

Reactive nitrogen fluxes over peatland (Bourtanger Moor) and forest (Bavarian Forest National Park) using micrometeorological measurement techniques

, 2022
Within the framework of the research projects NITROSPHERE and FORESTFLUX, field campaigns were carried out to investigate the biosphere-atmosphere exchange of reactive nitrogen compounds.
