To advance the biological understanding of heat shock protein (HSP) in different types of cancers, it is crucial to achieve its accurate determination. Herein, a dual-mode self-powered photoelectrochemical (PEC) and colorimetric platform was proposed by integrating enzymatic catalysis and a chemical redox cycling amplification strategy. In this system, ascorbic acid (AA), as the signal reporter for PEC and colorimetric assay, can be regenerated during the tris(2-carboxyethyl) phosphine-mediated chemical redox cycling process.

- The study examined how different carbon/nitrogen (C/N) ratios in sequencing batch biofilm reactors (SBBR) affect nitrogen removal from mariculture effluent, finding that a higher C/N ratio led to impressive nitrogen removal rates, achieving 95% for ammonia nitrogen and 73% for total nitrogen at a ratio of 30.
- The effect of the seed sludge was minimal, but a higher C/N ratio resulted in more tightly bound extracellular polymeric substances (TB-EPS), which closely correlated with nitrogen removal efficiency.
- Additionally, while high C/N ratios inhibited certain ammonia-oxidizing archaea and bacteria, they promoted other bacteria involved in nitrogen removal, highlighting the importance of C/N ratios in optimizing biological processes for wastewater treatment
Based on network pharmacology, molecular docking, and in vitro experimental verification, this study aims to explore the effect of Albiziae Cortex-Tribuli Fructus combination on HSC-LX2 pyroptosis. Specifically, the targets of Albiziae Cortex, Tribuli Fructus, and hepatic fibrosis were retrieved from an online database and CNKI, and "drug-component-target" network and "drug-component-target-disease" network were constructed. Protein-protein interaction(PPI) network was established based on STRING.

Of note, the term rural children includes rural left-behind children (LBC) and rural non-left-behind children (NLBC); the difference in the prevalence of intestinal helminths between the 2 groups remains unclear. In this study, Gulin and Xuyong counties in southern Sichuan were chosen for investigation in 2019.

- Rare-earth elements (REEs) are emerging pollutants, yet their geochemistry in rivers affected by ion-adsorption mining is understudied.
- Samples collected from a mining-impacted river showed significantly higher concentrations of REEs in smaller water fractions (<0.45 μm) compared to a control site, with varying factors affecting REE distribution between upstream and downstream.
- The study found that upstream REE transport was influenced by ligand complexation and smaller colloids, while downstream concentrations were driven by larger colloids and particle adsorption, highlighting the importance of REE patterns for understanding their behavior in mining-affected areas.
Probe bismuth sulfide modified with Pluronic F127 (Bi2S3-PF127), which has high biocompatibility and dispersibility, is synthesized using triblock copolymer Pluronic F127 to modify hydrophobic Bi2S3 nanoparticles that are prepared by a hot injection method. TEM results show that most of the probe has a length of about 14.85 ± 1.
