Lignin, one of the most abundant renewable feedstock, is used to develop a biocompatible hydrogel as anti-infective ointment. A hydrophilic polyoxazoline chain is grafted through ring opening polymerization, possess homogeneous spherical nanoparticles of 10–15 nm. The copolymer was covalently modified with triazole moiety to fortify the antimicrobial and antibiofilm activities. The hydrogel was capable of down regulating the expression level of IL-1β in LPS induced macrophage cells, and to cause significant reduction of iNOS production. It supported cellular anti-inflammatory activity which was confirmed with luciferase assay, western blot, and NF-κB analysis. This novel lignin-based hydrogel tested in-vivo has shown the abilities to prevent infection of burn wound, aid healing, and an anti-inflammatory dressing material. The hydrogel reported here provides a new material platform to introduce a cost-effective and efficient ointment option after undertaking further work to look at its use in the area of clinical practice.
An operationally simple C–SCN and C–SeCN bond formation technique to generate different SCN/SeCN substituted 4-quinolone derivatives using NH4SCN/KSeCN in excellent yields was developed.
Two novel boron-tolerant, arsenic-resistant, Gram-positive bacterial strains, Lysinibacillus sp. OL1 and Enterococcus sp. OL5, were isolated from boron fertilizer-amended cauliflower plantation field soils in India. Here, we report the draft genome sequences of OL1 (4.87 Mb) and OL5 (3.93 Mb) to explore the intricacies of boron tolerance in bacteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
