Longitudinal association of frailty levels with knee osteoarthritis in middle-aged and elderly chinese: a longitudinal cohort study - Scientific Reports
Abstract Frailty and Knee osteoarthritis (KOA) are highly prevalent in middle-aged and elderly populations. However, evidence on the longitudinal association of frailty with KOA is limited. The aim of our study was to explore the longitudinal effects of frailty levels on KOA, combining phenotypic frailty and frailty index(FI), using Cox regression analysis in a prospective cohort.

Microwave-assisted-demulsification dispersive liquid-liquid microextraction coupled with gas chromatography-mass spectrometry for the determination of PAHs in water
In this study, a novel technology of microwave-assisted-demulsification dispersive liquid liquid microextraction (MAD-DLLME) was developed for the extraction of polycyclic aromatic hydrocarbons (PAHs) in enviromental water samples, which was followed by gas chromotgraphy-mass spectrometery (GC-MS). The key of MAD-DLLME is based on the formation of an emulsion, where target analytes can partition between two phases, and subsequent employing microwave irradiation to achieve phase separation.
Microwave-assisted deep eutectic solvent extraction coupled with headspace solid-phase microextraction followed by GC-MS for the analysis of volatile compounds from tobacco - Analytical Methods (RSC Publishing)
A novel method of microwave-assisted deep eutectic solvent extraction coupled with solid-phase microextraction was developed to determine the volatile compounds in tobacco by gas chromatography-mass spectrometry. During the process, the deep eutectic solvent played the roles of absorbing medium for microwave radiation, destroyer of cell walls, and solvent for dissolving the compounds released from the cells.
Microwave-assisted deep eutectic solvent extraction coupled with headspace solid−phase microextraction followed by GC-MS for analysis of volatile compounds from tobacco - Analytical Methods (RSC Publishing)
A novel method that microwave-assisted deep eutectic solvent extraction coupled with solid?phase microextraction was developed to determine the volatile compounds in tobacco by gas chromatography-mass spectrometry. During the process, deep eutectic solvent played not only as the absorbing medium of microwave but also as the destructor of cell wall and as a solvent to dissolve the compounds released from cells.
