Organic Polyurethane Surface Structures to Manufacture Noneluting Antimicrobial Polyurethanes: A Systematic Review of Literature

BioMed Research International, Volume 2026, Issue 1, 2026.
The dramatic increase in hospital‐acquired infections and healthcare costs associated with infection treatment and antimicrobial resistance in implant infections necessitates further research and development of antimicrobial implant material properties. Polyurethanes are key biomaterials used in medical implants and devices.

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.

Dietary Flavonoids in Allergic Disease: Immunomodulatory Mechanisms and Therapeutic Potential

Journal of Food Quality, Volume 2026, Issue 1, 2026.
The rising global prevalence of allergic diseases is increasingly linked to modern dietary shifts, positioning dietary intervention as a critical strategy for disease prevention and management. Dietary flavonoids, a prominent class of bioactive polyphenols ubiquitous in plant‐based foods, offer a promising nutritional approach to mitigating allergic ...

TDI coupling chemistry as an efficient alternative to silane-based methods for the synthesis of silica-based metal chelators

Journal of Taibah University for Science
This study used toluene 2,4-diisocyanate (TDI) as a flexible linker to attach functional ligands onto silica through stable urethane bonds. Four chelating sorbents were prepared by coupling 8-hydroxyquinoline (HQ), 2,3-dihydroxypyridine (DHP), 1-nitroso ...

A biodegradable copolymer from coupling poly(pdioxanone) with poly(ethylene succinate) via toluene-2,4- diisocyanate

e-Polymers, 2009
AbstractPoly(p-dioxanone) (PPDO) and poly(ethylene succinate) (PES) prepolymers were reacted together using toluene-2,4-diisocyanate (TDI) as a chain extender to produce high molecular weight of chain-extended products of PPDO and PES (PPDOES) in a suitable reaction condition.
