Reactive nitrogen and oxygen species in airway inflammation

European Journal of Pharmacology, 2001
The free radical nitric oxide (NO) is an important mediator of many biological processes. Interestingly, the molecule appears to be a two-edged sword. Apart from NO having a function as a paracrine messenger, NO-derived oxidants are important weapons against invading pathogens. The role of NO in the airways is similarly ambiguous. Besides the task as a

Reactive Oxygen and Nitrogen Species

2004
The term “radical” is often used loosely in chemistry to refer to various groups of atoms that behave as a unit, such as the carbonate radical (CO 3 sup2- ), nitrate radical (NO 3 sup- ), and the methyl radical (CH3p-). According to this definition, Lavoisier (1789) has already indicated that the four elements: phosphorus, sulphur, carbon, and hydrogen

Interaction of lidocaine with reactive oxygen and nitrogen species

European Journal of Anaesthesiology, 2001
To investigate the ability of lidocaine to inhibit reactive oxygen and/or nitrogen species generation by either human leukocytes or cell-free systems via luminol- and lucigenin-enhanced chemiluminescence.Venous blood was obtained from healthy volunteers and leukocytes were isolated, from which chemiluminescence was generated.

Imaging of Intracellular Reactive Nitrogen Species and Reactive Sulfur Species

2020
This chapter summarizes representative small-molecule fluorescent probes for reactive nitrogen species and reactive sulfur species in living cells. The design and response mechanisms of the probes are described in detail. Probes that have not been applied in living cell analysis are not included.

Characterization of reactive nitrogen species in allergic asthma

Annals of Allergy, Asthma & Immunology, 2014
To investigate the molecular mechanism of reactive nitrogen species (RNS) in the pathogenesis of asthma and examine the use of fractional exhaled nitric oxide (FENO) measurements in close conjunction with standard clinical assessments of asthma.Through PubMed, Google Scholar, and Medline databases, a broad medical literature review was performed in the

Regulation of ryanodine receptors by reactive nitrogen species

Biochemical Pharmacology, 1999
The ryanodine receptors (RyRs) are large intracellular calcium release channels that play an important role in the control of the calcium levels in excitable and non-excitable cells. Many endogenous modulators such as Mg2+, ATP, or calmodulin can affect the channel activities of the three known mammalian RyR isoforms.

Reactive oxygen species, reactive nitrogen species and redox signalling

2016
This chapter explains our current understanding of how reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated and perceived, and how they propagate their messages. It argues that the main components involved here include those used in phosphorylation and cyclic nucleotides.
