Cancer-associated fibroblasts promote malignant phenotypes of prostate cancer cells via autophagy : Cancer-associated fibroblasts promote prostate cancer development.

Dysregulation of autophagy in cancer-associated fibroblasts (CAFs) has been demonstrated to play a role in malignant phenotypes of human tumors. We intended to investigate the function of CAFs autophagy in prostate cancer (PCa). Firstly, CAFs and normal fibroblasts (NFs) were isolated from cancerous and adjacent normal tissues of PCa patients, for the following experimental preparation.

Sonodegradation and photodegradation of methyl orange by InVO4/TiO2 nanojunction composites under ultrasonic and visible light irradiation.

The InVO(4)/TiO(2) nanojunction composites with different weight ratio of 1:10, 1:25, 1:50 and 1:100 were successfully constructed using an ion impregnate method, followed by calcining temperature 400°C for 2h in Ar. The sono- and photo-catalytic activities of the InVO(4)/TiO(2) nanojunction composites were evaluated through the degradation of methyl orange (MO) in aqueous solution under ultrasonic and visible light irradiation, respectively. The experimental results determined that the (1:50) InVO(4)/TiO(2) nanojunction composite has exhibited the highest sonocatalytic activity.

A novel fluorescent distinguished probe for Cr (VI) in aqueous solution.

Salicylaldehyde rhodamine B hydrazone (SRBH) was developed as a new spectrofluorimetric probe for the selective and sensitive detection of CrO(4)(2-) in acidic conditions. The proposed method was based on the special oxidation reaction between non-fluorescent SRBH by potassium dichromate to produce a highly fluorescent rhodamine B, as a product. Under the optimum conditions described, the fluorescence enhancement at 591 nm was good linearly related to the concentration of CrO(4)(2-) from 1.

[Hydrothermal synthesis of Co9S8 nanocrystalline aggregations and spectral study].

Co9S8 nanocrystalline aggregations were synthesized in hydrazine hydrate (N2H4 x H2O) solvent at 180 degrees C for 12 h through a hydrothermal method using cobalt sulfate hydrate (CoSO4 x 7H2O) and sodium sulfate (Na2SO3) as the starting materials. The prepared samples were characterized using X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM), and transmission electron microscope (TEM). FTIR spectrum was measured using Fourier-transform infrared spectrometer.

[Spectral research on the effect various metal ions on the of photocatalytic degradation properties of TiO2 nanocrystal].

TiO2 nanocrystalline was prepared by a emulsion method in the mixed solvent of cyclohexane and acetic anhydride using, titanyl organic compound as the precursor. The prepared product was characterized by means of X-ray diffraction (XRD) and Fourier transform infrared spectrum (FTIR). The photocatalytic oxidation of methyl orange with TiO2 loaded with various metal ions was discussed.

[Synthesis of nanocrystalline ZnO and its luminescence spectrum].

ZnO nanocrystal was prepared with Zn(CH3COO)2.2H2O and CO(NH2)2 as precursor by a solvothermal process. The products were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), and photoluminescence spectrum (PL).
