Summary: The study revealed that both Ag+ and Ag NPs exerted growth-inhibiting effects on Tetrahymena thermophila, mainly due to high levels of ROS causing oxidative stress, leading to lipid peroxidation and mitochondrial dysfunction. Additionally, 1250 lncRNAs were differentially expressed under exposure to Ag+ or Ag NPs, potentially regulating cell growth and oxidoreductase activity through co-expressed mRNAs.

Summary: This study investigated the effects of silver nanoparticles and zinc oxide nanoparticles on zebrafish embryos in aquatic environments. The research found that spiking these nanoparticles into natural water samples had a toxic effect on the embryos, with the level of toxicity influenced by complex components in the water. Additionally, zinc oxide nanoparticles caused a delay in embryo hatching. Measurement of reactive oxidative stress levels, apoptosis, and autophagy revealed the interaction and toxicity mechanisms of the nanoparticles with the embryos.

Summary: Fusarium graminearum is a destructive fungal pathogen causing Fusarium head blight (FHB) disease in cereal crops, leading to yield loss and mycotoxin contamination. Silver nanoparticles (AgNPs) show effective antifungal activity against fungicide-resistant and fungicide-sensitive F. graminearum strains, while inducing ROS generation, DON biosynthesis gene expression, and mycotoxin production. AgNPs have the potential to manage FHB in combination with DON-reducing fungicides.

Summary: Bacterial motility can be a significant predictor of AgNP resistance, guiding the development of nanoenabled antimicrobials. The study of bacterial resistance to AgNPs is still in its early stages, with limited understanding of the underlying mechanisms. The resistance to subinhibitory concentrations of AgNPs in Escherichia coli K-12 MG1655 strain was found to be associated with a cusS mutation, potentially enhancing silver ion efflux and suggesting a role for flagellum-based motility in the resistance mechanism.

Summary: This study investigated the formation mechanisms of silver nanoparticles (AgNPs) when Ag+ coexists with biomasses (BMs) and biochars (BCs). Different types of BMs and BCs were found to play different roles in transforming Ag+ to AgNPs, with temperature and pH having significant impact on the process. The results illustrate the importance of hydroxyl (-OH) groups in BMs and BCs for the reduction of Ag+ and the subsequent formation of AgNPs in the environment.

Summary: Soybean oil, which is composed of five fatty acids, including linoleic acid (LA), is known for its poor oxidative stability. In this study, we conducted a genome-wide association study (GWAS) using 510 soybean cultivars collected from China to explore the genetic architecture of LA. We identified 37 genes related to oleic acid content, with one candidate gene, Glyma.04G116500.1 (GmWRI14), consistently detected over three years. Overexpression of GmWRI14 resulted in a significant reduction in LA content in soybean seeds, and RNA-seq analysis confirmed that the downregulation of the FAD2 gene is the underlying mechanism. This study provides novel insights into the genetic control of LA in soybean and identifies potential candidate genes for further investigations.

Summary: With the widespread use of nanotechnology in the food industry, humans are increasingly exposed to engineered nanoparticles (NPs) in food. These NPs interact with beneficial bacteria in the human digestive tract, affecting their growth and triggering biotransformation. This study investigated the effects of different NPs on Streptococcus salivarius K12, a beneficial bacterium in the oral cavity, and observed changes in gene expression and NP transformations. The results suggest that food-related NPs can impact the competitiveness of beneficial bacteria and their activities influence the fate and toxicity of NPs in the digestive tract.

Summary: This study monitored a fully instrumented biocover at a closed landfill in Saaremaa Island, Estonia, to reduce methane emissions. After 10 years of monitoring, changes in methane, carbon dioxide, and temperature were observed. The study found that methane concentration and oxidation process activity varied across the biocover layer at different depths within the landfill. Based on data analysis, the methane oxidation process stabilizes in the biocover within 5-6 years after implementation.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
