Summary: A recyclable peroxidase mimic Fe3O4@polydopamine/Prussian blue composite was prepared and exhibited excellent peroxidase-like activity. The catalytic behavior followed typical Michaelis-Menten kinetics and the catalytic mechanism was deduced to be the nanozyme-promoted generation of a hydroxyl radical. A simple and fast colorimetric method for detection of Cr(vi) was developed based on the Cr(vi)-boosted peroxidase-like activity of Fe3O4@PDA/PB.

Summary: Due to the neural toxicity of mercury, a new colorimetric mercury detection probe, Fe3O4@SiO2@Au (magnetic-Au; Mag-Au) hybrid nanoparticles, has been developed for on-site detection of Hg2+. The presence of Hg2+ forms an AuHg alloy (amalgam) on the surface of Mag-Au, with excellent peroxidase-like activity. The oxidation of a substrate leads to a color change, allowing the detection of Hg2+ at nanomolar concentrations. Magnetic separation can be used to purify and concentrate the Mag-Au@Hg from samples, avoiding interference from unwanted residues or colored samples. The feasibility of Mag-Au for Hg2+ detection has been validated with artificial urine solution and can be applied to various real samples.

Summary: This study explored the relationship between the chain structure of corn starch and the properties of corn starch-based films. The degree of gelatinization, chain length distribution, amylose content, and molecular weight of the corn starch were determined. The films formed with starch pastes showed changes in thickness, surface roughness, solubility, water content, water vapor permeability, mechanical properties, and maximum thermal degradation rate with increasing heat treatment temperature. The decrease in amylose content led to a change in the performance of the corn starch-based films.

Summary: This study investigated the synergistic effects of electrokinetic remediation (EKR) on antibiotic resistance and arsenic (As) contamination in paddy soils. The study found that EKR treatments with pig manure amendment showed better remediation efficiency, reducing the content of available As and the abundance of antibiotic-resistant bacteria. The electric field played a significant role in antibiotic degradation and certain types of antibiotic resistance genes were easier to remove. Brevundimonas was found to be the most significantly different species during remediation, and Bacillus and Clostridium_ sensu_stricto_1 were potential host bacteria for antibiotic resistance genes in the electric field. Membrane transport was identified as an effective strategy for microorganisms to respond to the stress of electric field and co-contamination.

Summary: Musclin has been shown to attenuate inflammation, oxidative stress, and apoptosis in cardiomyocytes. However, its effects on hepatic endoplasmic reticulum (ER) stress and lipid metabolism are not fully understood. This study demonstrated that musclin treatment can reduce lipid accumulation and lipogenic protein expression in hepatocytes exposed to palmitate, and it can suppress palmitate-induced ER stress by upregulating SIRT7 and autophagy signaling.

Summary: In this study, a method was developed to rapidly detect organophosphorus pesticides (OPs) by combining TLC and enzyme inhibition principles. After removing organic solvents from the samples using TLC and paper-based chips, the enzyme was introduced to the detection system. The results demonstrated that this method effectively minimized the influence of solvents on enzyme behavior. Additionally, the pigments could be retained on TLC using a 40% ddH2O/ACN solution as a developing solvent. The method exhibited high sensitivity and provided valuable insights for sample pretreatment and rapid determination of pesticide residues in food.

Summary: This study examined the changes in the structure and properties of starch derived from waxy, stick, and H37 sorghum varieties at different stages of development. The results showed that as sorghum plants matured, the shape of starch granules became distorted, their size gradually increased, and porous and inner growth rings developed. Amylose content played a limiting role in the crystallinity of H37 starch, while the impact of CLD on various factors of starch structure was more pronounced. The study also conducted a correlation analysis between the structural and property aspects, providing valuable insights for starch modification.

Summary: This study reveals the adaptation and evolution characteristics of Goose astroviruses (GoAstVs) in the host environment. The study identifies two clusters of GoAstVs with consistent compositional characteristics. The analysis shows a high degree of fitness of GoAstVs to the host's codon usage patterns, indicating a strong adaptive pressure. Additionally, the study finds that GoAstVs have lower adaptability to ducks and chickens compared to geese, which may explain the difference in prevalence among these species. The suppression of CpG and UpA motifs in the virus genome facilitates the evasion of the host's innate immune system.
