AI Article Synopsis

  • The study examines how 2-Chlorobenzylidenemalononitrile (CS), commonly used as a riot control agent, breaks down into various compounds when heated to high temperatures.
  • Researchers conducted experiments exposing purified CS to temperatures between 300 to 900 degrees Celsius in a controlled environment, followed by analysis of the resulting gases.
  • The findings suggest that the formation of these CS-derived compounds during high-temperature dispersion is primarily due to the heat applied during the process.

Article Abstract

2-Chlorobenzylidenemalononitrile (CS riot control agent) has been shown to produce a number of thermal degradation products when dispersed at high temperature. We hypothesized that these CS-derived compounds are formed by energy input from heating during the dispersion process. Here we identified organic CS-derived compounds formed from purified CS subjected to temperatures ranging from 300 to 900 degrees C in an inert atmosphere with analysis of tube furnace effluent by gas chromatography and mass spectrometry. We conclude that the production of many CS-derived compounds previously observed during high-temperature dispersion is likely to be heat related.

Article Synopsis
  • - Polysaccharide-based adhesives, particularly chitosan-derived ones, present eco-friendly options but often lack strong adhesion.
  • - This study introduces a novel core-shell structure (SiO-NH@OPG) inspired by lobster anatomy, blending it with chitosan to create an effective wood adhesive (SiO-NH@OPG/CS).
  • - The new adhesive not only cures with heat but also at room temperature through water evaporation, and its unique microstructure enhances the strength and performance of wood composites.

Chondroitin sulfate (CS) is a glycosaminoglycan, and CS derived from various animal species is used in drugs and food supplements to alleviate arthralgia. The CS is a high molecular weight compound, and hydrolysis of CS by intestinal microbiota is thought to be required for absorption in mammalians. Chondroitin sulfate oligosaccharides (Oligo-CS) are produced by hydrolysis with subcritical water from CS isolated from a species of skate, Raja pulchra for the improvement of bioavailability.

Costello syndrome (CS) patients suffer from a very high 10% incidence of embryonal rhabdomyosarcoma (ERMS). As tools to discover targeted therapeutic leads, we used a CS patient-derived ERMS cell line (CS242 ERMS) harboring a homozygous p.G12A mutation in , and a control cell line derived from the same patient comprising non-malignant CS242 fibroblasts with a heterozygous p.

Acrolein is a major thiol-reactive component of cigarette smoke (CS) that is thought to contribute to increased asthma incidence associated with smoking. Here, we explored the effects of acute acrolein exposure on innate airway responses to two common airborne allergens, house dust mite and Alternaria alternata, and observed that acrolein exposure of C57BL/6 mice (5 ppm, 4 h) dramatically inhibited innate airway responses to subsequent allergen challenge, demonstrated by attenuated release of the epithelial-derived cytokines IL-33, IL-25, and IL-1α. Acrolein and other anti-inflammatory thiol-reactive electrophiles, cinnamaldehyde, curcumin, and sulforaphane, similarly inhibited allergen-induced production of these cytokines from human or murine airway epithelial cells in vitro.
