Kartogenin-Loaded Exosomes Derived From Bone Marrow Mesenchymal Stem Cells Enhance Chondrogenesis and Expedite Tendon Enthesis Healing in a Rat Model of Rotator Cuff Injury.

Background: The insufficient regeneration of fibrocartilage at the tendon enthesis is the primary cause of retearing after surgical reattachment of the rotator cuff. Exosomes derived from bone marrow-derived mesenchymal stem cells (BMSC-Exos) and kartogenin (KGN) have been demonstrated to induce fibrocartilage formation. Loading drugs into exosomes may lead to a synergistic effect, significantly enhancing the inherent activity of both components.

Recyclable magnetic carbonaceous porous composites derived from MIL-100(Fe) for superior adsorption and removal of malachite green from aqueous solution.

Development of novel porous materials for efficient adsorption and removal of environmental pollutants from aqueous solution is of great importance and interest in environmental science and chemistry. Herein, we reported a facile synthesis of recyclable magnetic carbonaceous porous composite derived from iron-based metal-organic framework MIL-100(Fe) for superior adsorption and removal of malachite green (MG) from aqueous solution. Because of large surface area and high porosity, the synthesized magnetic carbonaceous porous material presented a superior adsorption capacity of 2090 mg g for MG.

Pyrolytic in situ magnetization of metal-organic framework MIL-100 for magnetic solid-phase extraction.

In this study, we report a facile, environmental friendly fabrication of a type of magnetic metal-organic framework (MOF) MIL-100 that can be used for magnetic solid-phase extraction (MSPE). The magnetic MOF composites were fabricated using in situ calcination method. The as-synthesized materials exhibited both high porosity and magnetic characteristics.

Preparation and characterization of poly(AA co PVP)/PGS composite and its application for methylene blue adsorption.

Poly (AA co PVP)/PGS (PAPP) composite adsorbent was prepared by radical polymerization from Acrylic acid (AA), Polyvinylpyrrolidone (PVP) and Palygorskite (PGS), using N,N-methylenebisacrylamide (MBA) as cross-linker and potassium persulfate (KPS) as initiator. The PAPP was characterized with Fourier transform infrared (FT-IR), thermogravimetric analysis (TG), scanning electron microscope (SEM) and transmission electron microscopy (TEM). PAPP was used as adsorbent for the removal of methylene blue from aqueous solutions.
