Regulation of immune microenvironments by polyetheretherketone surface topography for improving osseointegration.

Optimizing the immune microenvironment is essential for successful implant osseointegration. In this study, four different nano/microstructures were fabricated on polyetheretherketone (PEEK) substrates by varying the agitation speed during sulfonation to influence osteoimmunomodulation and implant integration. The results indicate that nano/microstructures with minimal dimensions (SP450) inhibit actin polymerization by reducing calcium influx through PIEZO1, activating the anti-inflammatory M2 macrophage phenotype.

Determination of polychlorinated biphenyls in water by CO-responsive switchable deep eutectic solvent based homogeneous liquid-liquid microextraction.

A homogeneous liquid-liquid microextraction technique based on switchable deep eutectic solvent (SDES-HLLME), combined with gas chromatography-triple quadrupole tandem mass spectrometry (GC-MS/MS), was developed for the extraction and analysis of 16 polychlorinated biphenyls (PCBs) in water samples. CO-responsive switchable deep eutectic solvent (SDES), which consists of monoethanolamine (MEA) being used as a hydrogen bond acceptor (HBA) and 3-methoxyphenol (3-MP) being used as a hydrogen bond donor (HBD), was used as the extractant, thus providing an environmentally friendly alternative to conventional toxic organic solvents. The study systematically investigated the effects of various parameters on extraction efficiency, including the type and volume of SDES, vortexing duration, CO bubbling time, centrifugation rate and time, ionic strength.
