Reaction-Based Fluorescent Probes for the Detection and Imaging of Reactive Oxygen, Nitrogen, and Sulfur Species. [PDF]

Acc Chem Res, 2019
This Account describes a range of strategies for the development of fluorescent probes for detecting reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive (redox-active) sulfur species (RSS). Many ROS/RNS have been implicated in pathological processes such as Alzheimer's disease, cancer, diabetes mellitus, cardiovascular disease,

Navigating the dichotomy of reactive oxygen, nitrogen, and sulfur species: detection strategies and therapeutic interventions. [PDF]

RSC Chem Biol
This review discusses the dichotomic role of reactive oxygen, nitrogen, and sulfur species (RONSS) in disease pathogenesis highlighting RONSS-targeted chemical probes and prodrugs for the detection and mitigation of RONSS-associated conditions.

The impact of elevated sulfur and nitrogen levels on cadmium tolerance in Euglena species

Scientific Reports, 2023
AbstractHeavy metal (HM) pollution threatens human and ecosystem health. Current methods for remediating water contaminated with HMs are expensive and have limited effect. Therefore, bioremediation is being investigated as an environmentally and economically viable alternative.

Pregermination Studies with Liquid Nitrogen and Sulfuric Acid on Several Rubus Species [PDF]

HortScience, 1996
We contrasted the effect of liquid nitrogen (LN2), sulfuric acid (H2SO4), and a nontreated control on the germination of six Rubus species. We also were interested in determining if LN2 could be an effective mechanical scarifying agent for these species. Seeds of each species were treated with three 3-minute dips in LN2 with alternating 10-minute thaws,

Remnants of an ancient metabolism without phosphate [PDF]

, 2017
Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.

Vertical abundance stratification in the blue horizontal branch star HD135485 [PDF]

, 2007
It is commonly believed that the observed overabundances of many chemical species relative to the expected cluster metallicity in blue horizontal branch (BHB) stars appear as a result of atomic diffusion in the photosphere. The slow rotation of BHB stars

Polyisoprene Captured Sulfur Nanocomposite Materials for High-Areal-Capacity Lithium Sulfur Battery [PDF]

, 2019
A polyisoprene-sulfur (PIPS) copolymer and nano sulfur composite material (90 wt % sulfur) is synthesized through inverse vulcanization of PIP polymer with micrometer-sized sulfur particles for high-areal-capacity lithium sulfur batteries.

Empirical nitrogen and sulfur critical loads of U.S. tree species and their uncertainties with machine learning

Science of The Total Environment, 2023
Critical loads (CLs) of atmospheric deposition for nitrogen (N) and sulfur (S) are used to support decision making related to air regulation and land management. Frequently, CLs are calculated using empirical methods, and the certainty of the results depends on accurate representation of underlying ecological processes.

Polyethers for biomedical applications. Polymerization of propylene oxide by organozinc/organotin catalysts [PDF]

, 1987
The polymerization of propylene oxide to obtain a high-molecular-weight polymer with an atactic structure required for the application as artificial blood vessels was investigated using combinations of organozinc and organotin compounds as catalyst.
