Reactive oxygen and nitrogen species in pulmonary hypertension [PDF]

open access: yesFree Radical Biology and Medicine, 2012
Pulmonary vascular disease can be defined as either a disease affecting the pulmonary capillaries and pulmonary arterioles, termed pulmonary arterial hypertension, or a disease affecting the left ventricle, called pulmonary venous hypertension. Pulmonary arterial hypertension (PAH) is a disorder of the pulmonary circulation characterized by endothelial

Harnessing reactive oxygen/nitrogen species and inflammation: Nanodrugs for liver injury

open access: yesMaterials Today Bio, 2022
Overall, 12% of the global population (800 million) suffers from liver disease, which causes 2 million deaths every year. Liver injury involving characteristic reactive oxygen/nitrogen species (RONS) and inflammation plays a key role in progression of ...

Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) in plants– maintenance of structural individuality and functional blend

open access: yesAdvances in Redox Research, 2022
The free radicals along with several reactive oxygen species (ROS) and reactive nitrogen species (RNS) are known to play a dual role in the biological living system which carries a substantial importance in terms of signal networking in plants.

Polyatomic Liquid Oxygen (PLO®): A new methodology for the production in aqueous solution of reactive oxygen and nitrogen species (RONS) to be applied in medical treatments

open access: yesAIP Advances, 2021
Free radicals play a pivotal role in cell physiology as “gaseous messengers/transmitters.” The radical superoxide (O2·−) and H2O2 molecules are called Reactive Oxygen Species (ROS); nitric oxide and peroxynitrite are named Reactive Nitrogen Species (RNS).

Investigation of reactive species using various gas plasmas† [PDF]

open access: yesRSC Advances, 2014
In this study, atmospheric nonequilibrium plasmas were generated with six gas species using a multi-gas plasma jet. Singlet oxygen, OH radicals, H radicals, and NO radicals, in reaction with a solution interface, were measured using electron spin ...

Recent advances of antioxidant low-dimensional carbon materials for biomedical applications

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
As the primary cause of many tissue damage and diseases, reactive oxygen species (ROS) and reactive nitrogen species (RNS) are well known to be extremely harmful to a variety of biological components in cells including lipids, proteins and DNA.

Roles of reactive oxygen and nitrogen species in pain [PDF]

open access: yesFree Radical Biology and Medicine, 2011
Peroxynitrite (PN; ONOO⁻) and its reactive oxygen precursor superoxide (SO; O₂•⁻) are critically important in the development of pain of several etiologies including pain associated with chronic use of opiates such as morphine (also known as opiate-induced hyperalgesia and antinociceptive tolerance).

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

open access: yes, 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.
