Choice of mouse strain influences the outcome in a mouse model of chemical-induced asthma. [PDF]

PLoS ONE, 2010
BACKGROUND: The development of occupational asthma is the result of interactions between environmental factors and individual susceptibility. We assessed how our model of chemical-induced asthma is influenced by using different mouse strains. METHODOLOGY/

Fire and heat resistant laminating resins based on maleimido and citraconimido substituted 1-(diorgano oxyphosphonyl) methyl -2,4- and -2,6- diaminobenzenes [PDF]

, 1987
A class of fire and heat resistant bisimide resins prepared by thermal polymerization of maleimido or citraconimido substituted 1-((dialkoxyphosphonyl) methyl)-2-4 and -2,6-diaminobenzenes are described. The polymer precursors are prepared by reacting 1-(

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

ChemSusChem, Volume 18, Issue 13, July 1, 2025.
Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...

Suppression of Histamine Signaling by Probiotic Lac-B: a Possible Mechanism of Its Anti-allergic Effect

Journal of Pharmacological Sciences, 2008
It has been shown that probiotic bacteria are effective for the treatment of allergic diseases. As histamine plays a central role in allergic diseases, it is possible that probiotic bacteria affect the allergy-related histamine signaling.

Recyclable Dynamic Covalent Networks Derived from Isocyanate Chemistry: The Critical Role of Electronic and Steric Effects in Reversibility

ChemSusChem, Volume 18, Issue 13, July 1, 2025.
The emergence of dynamic covalent networks, featuring dynamic covalent bonds formed through isocyanate‐involved chemistry, aims to substitute conventional, non‐recyclable polyurethanes and polyureas. The review examines the reversibility of these dynamic bonds and the relevant polymer networks from the lens of electronic and steric influences.The ...

Review and Future Perspectives on Lithium Battery Fire Safety: Focusing on Design of Organic Components

ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 4, July 2025.
This review summarizes the design scheme of organic components to improve the fire safety of lithium batteries in recent 5 years. Besides the development of electrolyte tends to be safer and more intelligent, the flame retardancy of separators which consist of organic polymer can also be improved by physical or chemical modification.

Intestinal obstruction in acute inhalational toluene 2,4-diisocyanate gas toxicity.

The international journal of occupational and environmental medicine, 2013
The isocyanates are widely used as precursors of polyurethane products, as well as carbamate insecticides. Toluene 2,4-diisocyanate (TDI) is one of the most important commercially used isocyanates. Humans may be exposed to TDI by inhalation, ingestion, dermal and eye contact.

Recycling of Polyurethane via Mechanocatalytic Methanolysis/Hydrolysis

ChemSusChem, Volume 18, Issue 12, June 17, 2025.
In this study, it is shown that up to 86% of soluble polyol can be recovered from the hydrolysis of polyurethane using a ball milling‐assisted process below 100 °C in the presence of NaOH, a small amount of H2O and a Cu/MgAlOx co‐catalyst. Polyurethane (PU) is the 6th most produced plastic on a global basis, and thus one of the most important targets ...
