Enhanced dewatering of dredging slurry by Fenton preoxidation and composite coagulants: optimization experiments and dewatering mechanisms.

In this work, the Fenton preoxidation and composite coagulant method was used to carry out the rapid dewatering experiment of Chaohu Lake (China) dredging slurry. The changes in extracellular polymeric substances (EPS), particle size distribution, zeta potential, specific resistance to filtration (SRF), and capillary suction time (CST) of the dredging slurry were characterized. The results showed that the molar ratio of HO and Fe had the greatest effect on the dewatering of dredging slurry by Fenton preoxidation.

Purification of dredged water by magnetic coagulation: Response surface optimization and dissolved organic matter removal characteristics.

In the present study, magnetic coagulation was used to treat dredged water and the response surface method was used to optimize process parameters. The dissolved organic matter (DOM) removal characteristics were characterized by three-dimensional fluorescence spectrometry and ultra-high resolution mass spectrometry. During the magnetic coagulation process, the suspended solids (SS) removal rate increased initially and then decreased under conditions of increasing magnetic powder dosage and stirring rate.

Clinical pathological characteristics and prognostic analysis of diabetic women with luminal subtype breast cancer.

This study selected luminal-type breast cancer patients as the study subjects. The patients were divided into groups according to the presence of diabetes and the types of medication used, and the patients' clinicopathological characteristics and prognostic indicators were explored. A total of 5,785 patients with luminal-type breast cancer admitted to Tianjin Medical University Cancer Institute and Hospital between January 2002 and December 2006 were selected as the study subjects.

[Effect mechanism of NOD like receptor signaling pathway on intestinal mucosal barrier of rat during early phase of acute intra-abdominal infection].

Objective: To initially investigate the expressing regularity and effect of enterocyte NOD like receptors on gut mucosal barrier during early phase of acute intra-abdominal infection.

Methods: Sprague-Dawley (SD) rats were randomly allocated into control group (n=6) and experimental group (n=24). Acute intra-abdominal infection model was induced by cecal ligation and puncture (CLP).
