While inward remodeling of small arteries in response to low blood flow, hypertension, and chronic vasoconstriction depends on type 2 transglutaminase (TG2), the mechanisms of action have remained unresolved. We studied the regulation of TG2 activity, its (sub) cellular localization, substrates, and its specific mode of action during small artery inward remodeling. We found that inward remodeli...

lidocaine (lc) is a local anesthetic agent. the aim of this study was to prolong the anesthetic effect of this drug in the oral cavity in the treatment of oral mucositis. films of lc were prepared with three different molecular weights (mw) of chitosan in three different concentrations (1-3%) and were then cross-linked by solvent casting evaporation method with tripolyphosphate penta sodium sal...

A new type of nanocomposite hydrogels based on covalent cross-linked interactions with excellent mechanical properties and good stability has been prepared by using in situ free-radical polymerization; polystyrene nanoparticles with photo-activity are used as the cross-linking agent.

The formation of interstrand cross-links in nucleic acids can have a strong impact on biological function of nucleic acids; therefore, many cross-linking agents have been developed for biological applications. Despite numerous studies, there remains a need for cross-linking agents that exhibit both efficiency and selectivity. In this study, a 4-vinyl-substituted analog of thymidine (T-vinyl der...
