Photo-crosslinkable, fumaric acid monoethyl ester-functionalized poly(trimethylene carbonate) oligomers were synthesized and copolymerized with N-vinyl pyrrolidone (NVP) and vinyl acetate (VAc) to form biodegradable polymer networks. The copolymerization reactions were much faster than homopolymerization of the fumarate end-groups of the macromers. The hydrophilicity of the networks could by varied by mixing NVP and VAc at different ratios. The prepared network extracts were compatible with NIH 3T3 fibroblasts. Release of vitamin B12, used as a model drug, could be tuned by varying network hydrophilicity and macromer molecular weight. A more hydrophilic and less densely crosslinked network resulted in faster release.

The electrochemical nitrate reduction reaction (NORR) is considered as a promising strategy for addressing environmental pollution and sustainable energy development. In this study, prism-like CuO loaded on copper foam (CuO/CF) was synthesized in a simple solvothermal reaction and an electrochemical reconstruction process. The electrochemical reconstruction process facilitates the formation of a CuO lattice structure on copper foam derived from FU-CF generated by the reaction of copper foam and fumaric acid (HFU) in DMF.

Asthma has been extensively studied in humans and animals, but the molecular mechanisms underlying asthma in Meishan pigs, a breed with distinct genetic and physiological characteristics, remain elusive. Understanding these mechanisms could provide insights into veterinary medicine and human asthma research. We investigated asthma pathogenesis in Meishan pigs through transcriptomic and metabolomic analyses of blood samples taken during autumn and winter.

Members of the genus are the conventional medicinal plants used in the therapeutic management of numerous ailments, especially for their antioxidant and pharmacological activities. The crude extract of was profiled using high-resolution GC-MS and LC-MS/MS techniques to determine possible bioactive compounds that are vital to the antioxidant activity. A total of 52 and 63 bioactive compounds have been detected in GC-MS chromatograms using different solvents (methanol and ethanol) in leaf extracts, representing the presence of certain bioactive compounds.
