Modulation of Fatty Acid Oxidation Alters Contact Hypersensitivity to Urushiols: Role of Aliphatic Chain β-Oxidation in Processing and Activation of Urushiols

open access: yesJournal of Investigative Dermatology, 1997
Lithraea caustica, or litre, a tree of the Anacardiaceae family that is endemic to the central region of Chile, induces a severe contact dermatitis in susceptible human beings. The allergen was previously isolated and characterized as a 3-(pentadecyl-10-enyl) catechol, a molecule belonging to the urushiol group of allergens isolated from poison ivy and

Surface modification of titania particles with urushiol (Japanese lacquer) and its application to the preparation of polymer-titania hybrids.

open access: yes, 2007
International audienceTo prep. stable polymer-titania hybrids, titania particles were modified using urushiol (extd. from Japanese lacquer) via surface complexation. The urushiol moieties underwent hydrosilylation and radical graft-polymn.

Effect of Increased Carbon Dioxide Levels on Urushiol Production in Toxicodendron radicans and Toxicodendron toxicarium

open access: yes, 2009
It is hypothesized that global warming is at least partially due to increased greenhouse gases, one of which is carbon dioxide. An increase in atmospheric carbon dioxide has been shown to stimulate higher rates of plant productivity, including the ...

Polymerization of Oriental Lacquer (Urushi) with Epoxidized Linseed Oil as a New Reactive Diluent

open access: yesInternational Journal of Polymer Science, 2015
A hybrid lacquer (HBL) paint prepared by combining a natural kurome lacquer (KL) paint and an amino silane reagent, for example, N-(2-aminoethyl)-3-aminopropyl triethoxysilane (AATES), produced a polymerized film faster than the KL paint alone.
