Chemiluminescence Measurement of Reactive Sulfur and Nitrogen Species

Antioxidants & Redox Signaling, 2022
Significance: Reactive sulfur and nitrogen species such as hydrogen sulfide (H2S) and nitric oxide (NO•) are ubiquitous cellular signaling molecules that play central roles in physiology and pathophysiology. A deeper understanding of these signaling pathways will offer new opportunities for therapeutic treatments and disease management. Recent Advances:

Release of nitrogen, sulfur and chlorine species from coal in carbon dioxide atmosphere

Fuel, 2021
Abstract In oxyfuel combustion, the release of minority species, such as sulfur, nitrogen and chlorine compounds from the fuel plays an essential role, since significant corrosion and emission issues arise from these species. In the present study, the release of nitrogen, sulfur and chlorine species from a US-American bituminous coal with high sulfur

Aircraft measurements of sulfur, nitrogen, and carbon species during WATOX‐86

Global Biogeochemical Cycles, 1987
Filter pack and aethalometer systems were successfully used aboard the National Oceanic and Atmospheric Administration WP‐3D and King Air aircraft during the January 1986 intensive field investigation of the Western Atlantic Ocean Experiment (WATOX) to measure concentrations of sulfur and nitrogen species and black carbon aerosol.

Reactive Oxygen, Nitrogen, and Sulfur Species (RONSS)‐Responsive Polymersomes for Triggered Drug Release

Macromolecular Rapid Communications, 2017
Reactive oxygen, nitrogen, and sulfur species (RONSS) are cross‐reacting and involved in a myriad of physiological and pathological processes. Similar to acidic pH, overexpressed enzymes, and other specific stimuli found in pathological microenvironments, RONSS are recognized as a category of emerging triggering events and have been employed to design ...

Spectrophotometric Quantification of Reactive Oxygen, Nitrogen and Sulfur Species in Plant Samples

2017
Reactive oxygen, nitrogen and sulfur species are key signalling molecules involved in multiple physiological processes that can be examined in qualitative and quantitative manners. Here, we describe simple spectrophotometric assays that allow the quantification of hydrogen peroxide, nitrite-derived nitric oxide and hydrogen sulphide from plant tissues.

Secondary Sulfur and Nitrogen Species in PM10 from the Rijeka Bay Area (Croatia)

Bulletin of Environmental Contamination and Toxicology, 2016
Samples of PM10 were collected over a 12 month period at two sites approximately 5 km apart. Site 1 was an urban site in the center of the city of Rijeka, Croatia, and Site 2 was an industrial site in the proximity of a shipyard, located in the southeastwards direction from the city.

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.

Effect of reactive oxygen, nitrogen, and sulfur species on signaling pathways in atherosclerosis

Vascular Pharmacology
Atherosclerosis is a chronic inflammatory disease in which fats, lipids, cholesterol, calcium, proliferating smooth muscle cells, and immune cells accumulate in the intima of the large arteries, forming atherosclerotic plaques. A complex interplay of various vascular and immune cells takes place during the initiation and progression of atherosclerosis.

Reaction-Based Luminescent Probes for Reactive Sulfur, Oxygen, and Nitrogen Species: Analytical Techniques and Recent Progress

Analytical Chemistry, 2019
Gasotransmitters and related reactive sulfur, oxygen, and nitrogen species such as nitric oxide (NO), hydrogen sul-fide (H2S), carbon monoxide (CO), hydrogen peroxide (H2O2) and downstream products like peroxynitrite (ONOO–), polysulfides (HSnH), hydroxyl radical (HO•), and azanone (nitroxyl, HNO) are produced under physiological condi-tions and impact

Comparison of Select Properties and Sulfur and Nitrogen Species in Low and Ultra Low Sulfur Diesel Fuel

SAE Technical Paper Series, 2008
<div class="htmlview paragraph">Aromatics, cetane number, density, and lubricity of a large number of retail diesel fuel samples were compared before, during, and after the switch from low sulfur to ultra low sulfur diesel fuel. Also, sulfur and nitrogen speciation was done on a small set of samples to determine the changes in heterocyclic ...
