Network Toxicology Prediction and Molecular Docking-based Strategy to Explore the Potential Toxicity Mechanism of Metformin Chlorination Byproducts in Drinking Water.

Background: Metformin (MET), a worldwide used drug for treating type 2 diabetes but not metabolized by humans, has been found with the largest amount in the aquatic environment. Two MET chlorination byproducts, including Y and C, were transformed into drinking water during chlorination. However, the potential toxicity of the byproducts in hepatotoxicity and reproduction toxicity remains unclear.

Performance and mechanism of a novel S-scheme heterojunction sonocatalyst CuS/BaWO for degradation of bisphenol A by ultrasonic activation.

A novel CuS/BaWO heterojunction catalyst was prepared and characterized. Taking bisphenol A as the target pollutant for catalytic degradation, the sonocatalytic activity of CuS/BaWO composite was evaluated, and the combination with persulfate improved the sonocatalytic degradation of bisphenol A. The results showed that CuS/BaWO composite had good sonocatalytic degradation activity for bisphenol A, and the degradation rate was 70.

A novel flavonoid with antioxidant activity from (Thunb.) Juss.

(Thunb.) Juss (), a perennial herb, is widely used as a medicinal plant in Chinese folk. This study aims to isolate and identify the chemical constituents from and evaluate their antioxidant activity.

[Distribution of polybrominated diphenyl ethers in wild crucian carp and exposure estimation of dietary intake].

The concentration and distribution of PBDEs in liver, heart, brain, egg and muscle tissues of market farmed fish and wild river fish (crucian carp) from Taizhou, which is a large e-waste recycling site in China, were quantitatively measured using gas chromatography -negative chemical ion tandem mass spectrometry (GC-NCI-MS). The dietary intake of PBDEs via the consumption of fish by the population of this region was also estimated. The results showed that the concentrations of PBDEs in the muscle of river fish samples near the e-waste recycling site were significantly higher than those in the market farmed fish without obviously polluted sources of PBDEs.

Image denoising using nonsubsampled shearlet transform and twin support vector machines.

Denoising of images is one of the most basic tasks of image processing. It is a challenging work to design a edge/texture-preserving image denoising scheme. Nonsubsampled shearlet transform (NSST) is an effective multi-scale and multi-direction analysis method, it not only can exactly compute the shearlet coefficients based on a multiresolution analysis, but also can provide nearly optimal approximation for a piecewise smooth function.
