Co-evolution of heterogeneous cognition in spatial snowdrift game with asymmetric cost.

The emergence of the evolutionary game on complex networks provides a fresh framework for studying cooperation behavior between complex populations. Numerous recent progress has been achieved in studying asymmetric games. However, there is still a substantial need to address how to flexibly express the individual asymmetric nature.

Ependymoma with metastases to the gallbladder: A case report and literature review.

Metastatic ependymoma of the gallbladder is an exceptionally rare condition that remains relatively unreported in the scientific literature. The present study described a case involving a 42-year-old female patient who underwent right frontal lobe surgery for ependymoma in 2017 and subsequently received adjuvant chemotherapy. The histological examination of the surgical specimen confirmed the presence of ependymoma metastasis in the gallbladder.

Sono-enhanced heterogeneous Fenton catalysis: magnetic halloysite nanotube synthesis and accelerated free radical generation.

Although heterogeneous Fenton catalysis has captured increasing attention compared to its homogeneous counterpart, it still confronts some inherent drawbacks in use, such as the dilemma in solid-liquid separation and greater mass transfer resistance. Driven by the acoustic cavitation effect, herein, a sono-enhanced heterogeneous Fenton catalysis process was built to overcome the above two shortcomings, by rapidly synthesizing magnetic Fenton-like catalysts and accelerating electron transfer during the catalytic reaction. The results show that, compared to the traditional chemical coprecipitation method, FeO with smaller particle size and better crystallinity grew on the surface of halloysite nanotubes (HNTs) by using the sonochemical strategy, leading to displaying the higher catalytic activity toward the degradation of methylene blue (MB, improved by ~2.

Preparation of Monolithic LaFeO and Catalytic Oxidation of Toluene.

Porous LaFeO powders were produced by high-temperature calcination of LaFeO precursors obtained by hydrothermal treatment of corresponding nitrates in the presence of citric acid. Four LaFeO powders calcinated at different temperatures were mixed with appropriate amounts of kaolinite, carboxymethyl cellulose, glycerol and active carbon for the preparation of monolithic LaFeO by extrusion. Porous LaFeO powders were characterized using powder X-ray diffraction, scanning electron microscopy, nitrogen absorption/desorption and X-ray photoelectron spectroscopy.

Akt-mediated mitochondrial metabolism regulates proplatelet formation and platelet shedding post vasopressin exposure.

Background: Platelet shedding from mature megakaryocytes (MKs) in thrombopoiesis is the critical step for elevating circulating platelets fast and efficiently, however, the underlying mechanism is still not well-illustrated, and the therapeutic targets and candidates are even less.

Objectives: In order to investigate the mechanisms for platelet shedding after vasopressin treatment and find new therapeutic targets for thrombocytopenia.

Methods: Platelet production was evaluated both in vivo and in vitro after arginine vasopressin (AVP) administration.

Design, luminescence properties and applications of Cr-doped ScTaO: a broadband near-infrared phosphor.

Near-infrared (NIR) emitting LED devices have broad applications. Using a visible light LED chip to excite Cr-activated phosphors to obtain NIR light has attracted extensive attention. In this study, a near-infrared luminescent material, Cr-doped ScTaO, was synthesized by the element substitution method.

Co-monomer polymer anion exchange resin for removing Cr(VI) contaminants: Adsorption kinetics, mechanism and performance.

Modified anion exchange resin (EDE-D301) was synthesized by mixing monomers: epichlorohydrin (ECH), dimethylamine (DMA), ethylenediamine (EDA) with the weakly alkaline anion exchange resin D301 through in-situ polymerization method. Adsorption performance of EDE-D301 for removing Cr(VI) contaminants was investigated in batch and column systems. Physicochemical properties of the anion exchange resins were characterized to determine the adsorption mechanism and regeneration ability.

The influence of algal organic matter produced by Microcystis aeruginosa on coagulation-ultrafiltration treatment of natural organic matter.

Cyanobacterial bloom causes the release of algal organic matter (AOM), which inevitably affects the treatment processes of natural organic matter (NOM). This study works on treating micro-polluted surface water (SW) by emerging coagulant, namely titanium sulfate (Ti(SO)), followed by Low Pressure Ultrafiltration (LPUF) technology. In particular, we explored the respective influence of extracellular organic matter (EOM) and intracellular organic matter (IOM) on synergetic EOM-NOM/IOM-NOM removal, functional mechanisms and subsequent filtration performance.

Parameter optimization method for the water quality dynamic model based on data-driven theory.

Parameter optimization is important for developing a water quality dynamic model. In this study, we applied data-driven method to select and optimize parameters for a complex three-dimensional water quality model. First, a data-driven model was developed to train the response relationship between phytoplankton and environmental factors based on the measured data.

Toxic effects of chrysoidine on human serum albumin: isothermal titration calorimetry and spectroscopic investigations.

Chrysoidine is widely used in industry as a type of azo dye, and is sometimes used illegally as a food additive despite its potential toxicity. Human serum albumin (HSA) is one of the most important proteins in blood plasma and possesses major physiological functions. In the present study, the conformational and functional effects of chrysoidine on HSA were investigated by isothermal titration calorimetry (ITC), multiple spectroscopic methods, a molecular docking study and an esterase activity assay.

[Comparison of antioxidant activity between two species of chamomiles produced in Xinjiang by TLC-bioautography].

Objective: To compare the antioxidant active components from two species of chamomile-matricaria and Roman chamomile produced in Xinjiang.

Method: The TLC-bioautography was used, with 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical as the experimental model. The peak areas of various antioxidant components were obtained by TLC-scanning for analyzing antioxidant active components contained in volatile oil extracts and flavone extracts from the two species of chamomiles.
