The predicting role of serum tumor-specific growth factor for prognosis of esophageal squamous cell carcinoma.

Objective: Tumor-specific growth factor (TSGF) is an immune-related factor that offers good performance in the clinical management of human cancers. However, the role of serum TSGF in esophageal squamous cell carcinoma (ESCC) has not been fully clarified.

Methods: A total of 562 ESCC cases were collected in our study, with available information on preoperative serum levels of TSGF at diagnosis.

Removal of humic acid from aqueous solution by magnetically separable polyaniline: adsorption behavior and mechanism.

Magnetically separable polyaniline (Fe3O4@SiO2-PANI) was prepared by in situ chemical polymerization of aniline on the surface of silica-coated Fe3O4 nanoparticles, and characterized by FTIR spectroscopy, powder X-ray diffraction, elemental analysis, transmission electron microscopy, vibrating sample magnetometry and X-ray photoelectron spectroscopy. Characterization results showed that Fe3O4@SiO2-PANI with amino groups of 1.78 mmol/g and the average diameter of 21.
