Preparation and characterization of maltodextrin-based polyurethane.

Maltodextrin (MD) based polyurethane (MDPU) was prepared by the reaction of MD and polyethyleneglicol (PEG) polyurethane prepolymer (PUP). The structure and properties of the MDPU were investigated by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (H NMR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), scanning electron microscope (SEM), Energy dispersive X-ray spectrometry (EDS), and tensile-testing machine in detail. Chemical structure of MDPU was confirmed by FTIR and H NMR.

[Impaired effect of BHC80 gene knock-down on the cardiac development in zebrafish].

The effect of BHC80 (a component of BRAF-HDAC complex) on development was not well studied, because BHC80 gene knock-out mice died in one day after birth. Interestingly, zebrafish embryos can live, even if their important organs like cardiac system has severe dysfunction, as 25%-40% O2 are supplied through their skin. Therefore, a model of BHC80 gene knock-down zebrafish embryos was established to explore the effect of BHC80 on the early embryonic development.

FoxP3 inhibits proliferation and induces apoptosis of gastric cancer cells by activating the apoptotic signaling pathway.

Forkhead Box Protein 3 (FoxP3) was identified as a key transcription factor to the occurring and function of the regulatory T cells (Tregs). However, limited evidence indicated its function in tumor cells. To elucidate the precise roles and underlying molecular mechanism of FoxP3 in gastric cancer (GC), we examined the expression of FoxP3 and the consequences of interfering with FoxP3 gene in human GC cell lines, AGS and MKN45, by multiple cellular and molecular approaches, such as immunofluorescence, gene transfection, CCK-8 assay, clone formation assay, TUNEL assay, Flow cytometry, immunoassay and quantities polymerase chain reaction (PCR).
