Reaction Cycles of Halogen Species in the Immune Defense: Implications for Human Health and Diseases and the Pathology and Treatment of COVID-19

Cells, 2020
There is no vaccine or specific antiviral treatment for COVID-19, which is causing a global pandemic. One current focus is drug repurposing research, but those drugs have limited therapeutic efficacies and known adverse effects. The pathology of COVID-19

Biologically Relevant Small Radicals

CHIMIA, 2008
Biologically relevant small radicals are at the focus of the working group 4 (WG4) of the COST Action CM0603 (Free Radicals in Chemical Biology, CHEMBIORADICAL). This article surveys the areas of research being undertaken by the partners in WG4.

Juggling with reactive oxygen species and antioxidant defense system – A coping mechanism under salt stress

Plant Stress, 2022
Even under optimal conditions many metabolic processes produce ROS like superoxide anion (O2.-), hydrogen peroxide (H2O2) and hydroxyl radicals (OH⋅), particularly in chloroplast and mitochondria.

What Did We Accomplish in Fighting Radical Species in Human Health?

Antioxidants, 2021
Maintaining the physiological level of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the body is highly important in the fight against radical species in the context of human health [...]

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.

Effects of Antimony on Reactive Oxygen and Nitrogen Species (ROS and RNS) and Antioxidant Mechanisms in Tomato Plants

Frontiers in Plant Science, 2020
This research studies the effects that Sb toxicity (0.0, 0.5, and 1.0 mM) has on the growth, reactive oxygen and nitrogen species, and antioxidant systems in tomato plants.

Dangers of hyperoxia

Critical Care, 2021
Oxygen (O2) toxicity remains a concern, particularly to the lung. This is mainly related to excessive production of reactive oxygen species (ROS). Supplemental O 2 , i.e. inspiratory O2 concentrations (FIO2) > 0.21 may cause hyperoxaemia (i.e.

Interplay between oxidant species and energy metabolism

Redox Biology, 2016
It has long been recognized that energy metabolism is linked to the production of reactive oxygen species (ROS) and critical enzymes allied to metabolic pathways can be affected by redox reactions. This interplay between energy metabolism and ROS becomes

Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]

, 2010
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.
