Synthesis, characterization and photocatalytic properties of InS/TiC composites.

Recently, the problem of water pollution, caused by antibiotics, is becoming more and more serious. Photocatalysis is one of the promising technologies for removing antibiotics from water. Herein, the InS/TiC composites were prepared by an in-situ hydrothermal growth method for photocatalytic degradation of tetracycline (TC).

AgBrO₃/Few-Layer g-C₃N₄ Composites: A Visible-Light-Driven Photocatalyst for Tetracycline Degradation.

The AgBrO₃/few-layer g-C₃N₄ composite photocatalyst has been developed via an in-situ synthetic method. The structure, morphology, light response range, separation and migration efficiency of the photogenerated electron-hole pairs and element valence state of the as-obtained samples have been characterized. The tetracycline was used to discuss the photocatalytic activities of the samples.

Zn₂SnO₄-Reduced Graphene Oxide Nanohybrids for Visible-Light-Driven Photocatalysis.

Zn2SnO4-reduced graphene oxide photocatalysts were synthesized by using SnCl4 5H2O, Zn(NO3)2 · 6H2O and graphene oxide via hydrothermal process. The structure, morphology, specific surface area and photo response of the as-prepared nanocomposites were characterized by X-ray diffraction, Transmission electron microscopy, UV-vis diffuse reflectance spectra, Brunauer-emmett-teller surface area measurement and Photoluminescence emission spectra. Experimental results showed that the Zn2SnO4 nanoparticles, with 20-30 nm a size range, were uniformly dispersed on the surfaces of reduced graphene oxide.

Zinc oxide/reduced graphene oxide composites with various morphologies and properties were prepared via a one-step solvothermal process. The formation of zinc oxide and reduction of graphene oxide were simultaneously accomplished. These as-obtained samples showed high performance in removing methylene blue from aqueous solution.

Preparation of Reduced-Graphene Nanoribbons via One-Step Solvothermal Process.

Carbon nanotubes were unzipped to become reduced-graphene nanoribbons via one-step solvothermal process in a Teflon-lined autoclave. The samples were characterized by X-ray diffraction, thermo-gravimetric analysis and transmission electrical microscopy, respectively. Results showed that the solvothermal reaction temperature played an important role in the structure of the samples.

[Effects of Tongxinluo on neuron ultrastructure and endothelial cell self-repairing ability in hypoxia preconditioning mice].

Objective: To observe the ultrastructure changes of cerebral cortex neuron and endothelial cell in hypoxia preconditioning mice and the effects of Tongxinluo (TXL, Chinese traditional medilihe) on them.

Methods: Mice were randomly divided into 4 groups: control group, hypoxia group, hypoxia preconditioning (HP) group and Tongxinluo (TXL) group. The hypoxia preconditioning mice were exposed by repetitive hypoxia for 5 runs.

Objective: To observe the effect of chronic psychological stress on vascular endothelial dysfunction rats and to explore the intervention and mechanism of Tongxinluo (TXL) on it.

Methods: Forty male Wistar rats were randomly divided into the normal control group (with no modeling), the endothelial dysfunction group (the HCY group), the psychological stress group (the model group), and TXL group, ten in each group. Rats in the latter three groups were fed with 3% high methionine diet to duplicate vascular endothelial dysfunction (VED) model.

[Effects of Tongxinluo on repeated hypoxic tolerance in mice].

Objective: To observe the effects of Tongxinluo (TXL) on repeated hypoxic tolerance in mice and explore the underlying mechanisms.

Methods: Mice were randomly divided into groups of repeated hypoxia (control) and TXL according to body weights. The mice in each group were exposed to acute repeated hypoxia for 0 run (H0), 1 run (H1), 3 runs (H3) and 5 runs (H5).

Objectives: To observe the effects of renal ischemic postconditioning (RI-Post) on myocardial apoptosis in rabbits with acute myocardial ischemia and reperfusion.

Methods: All rabbits were subjected to 60 minutes ischemia by left anterior descending coronary artery occlusion (LADO) and 6 hours reperfusion. The rabbits are randomly divided into 3 groups (n = 8 in each group): (1) Ischemia-reperfusion (IR): LADO and reperfusion without additional intervention; (2) RI-Post: after 60 minutes of LADO, the left renal artery was occluded for 30 seconds and reperfused for 30 seconds and repeated 3 times, then the coronary artery was reperfused for 6 hours; (3) Medication intervention (MI): 10 minutes before coronary reperfusion, rabbits were treated with PKC antagonist GF109203X (0.

Effects of Chinese herbs on multiple ion channels in isolated ventricular myocytes.

Background: Shensong Yangxin (SSYX) is one of the compound recipe of Chinese materia medica. This study was conducted to investigate the effects of SSYX on sodium current (I(Na)), L-type calcium current (I(Ca, L)), transient outward potassium current (I(to)), delayed rectifier current (I(K)), and inward rectifier potassium currents (I(K1)) in isolated ventricular myocytes.

Methods: Whole cell patch-clamp technique was used to study ion channel currents in enzymatically isolated guinea pig or rat ventricular myocytes.
