Effects of Shenqi Xiangyi granules in advanced gastric cancer chemotherapy.

Background: Owing to the absence of specific symptoms in early-stage gastric cancer, most patients are diagnosed at intermediate or advanced stages. As a result, treatment often shifts from surgery to other therapies, with chemotherapy and targeted therapies being the primary options for advanced gastric cancer treatment.

Aim: To investigate both treatment efficacy and immune modulation.

Fabrication of chitosan-based MCS/ZnO@Alg gel microspheres for efficient adsorption of As(V).

Groundwater contaminated by arsenic endangers our health. Therefore, in this work, a novel composite adsorbent consisting of magnetic chitosan (MCS), zinc oxide (ZnO), and sodium alginate (Alg) was prepared to remove arsenic from groundwater. First, chitosan was coated on the surface of FeO nanoparticles by coprecipitation.

Efficient adsorption of Pb(II) from aqueous solutions using aminopropyltriethoxysilane-modified magnetic attapulgite@chitosan (APTS-FeO/APT@CS) composite hydrogel beads.

The performance of FeO/attapulgite (APT) nanoparticles in Pb(II) adsorption from aqueous solutions could be improved by modifying the particles with aminopropyltriethoxysilane (APTS) and then combining with chitosan (CS) into beads. After preparing the APTS-FeO/APT@CS beads, their surface morphology and crystal phases were analyzed by Fourier-transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction. The magnetic properties of APTS-FeO/APT@CS were studied by a vibrating sample magnetometer, while their heat resistance and stability were characterized by thermal weight analysis.

Efficient adsorption of diclofenac sodium from aqueous solutions using magnetic amine-functionalized chitosan.

In this study, we prepared a magnetic composite based on amine-functionalized chitosan (aminochitosan; AmCS) and FeO to remove diclofenac sodium (DS) from water. The fabricated AmCS@FeO composite was characterized using Fourier-transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, vibrating sample magnetometry, X-ray diffraction, and thermogravimetric analysis. Furthermore, we investigated the influence of pH, initial DS concentration, and adsorbent dosage on the adsorption of DS.

Facile Preparation of Metal-Organic Framework (MIL-125)/Chitosan Beads for Adsorption of Pb(II) from Aqueous Solutions.

In this study, novel composite titanium-based metal-organic framework (MOF) beads were synthesized from titanium based metal organic framework MIL-125 and chitosan (CS) and used to remove Pb(II) from wastewater. The MIL-125-CS beads were prepared by combining the titanium-based MIL-125 MOF and chitosan using a template-free solvothermal approach under ambient conditions. The surface and elemental properties of these beads were analyzed using scanning electron microscopy, Fourier transform infrared and X-ray photoelectron spectroscopies, as well as thermal gravimetric analysis.
