Summary: The article describes a method to determine embryonic viability and brood size in Caenorhabditis elegans. This technique can be used to assess errors in meiosis, fertilization, and embryogenesis and is easily adoptable for new researchers. It is an excellent model organism for studying these processes.

Summary: The study compared the transgenerational toxicity of 20 nm and 100 nm polystyrene nanoparticles using Caenorhabditis elegans as a model, finding that exposure to 20 nm particles resulted in more severe toxicity than 100 nm particles due to differences in transgenerational activation of oxidative stress.

Summary: This study systematically verifies the adverse effects of MC-LR exposure on oxidative stress markers, health, functional traits, and performance traits in fish and mammals, and identifies MDA and LPO activities as indicators of oxidative stress. The study also highlights the impact of MC-LR exposure concentration on LPO, MDA, and growth.

Summary: This study used Caenorhabditis elegans as a model organism to investigate the toxic effects and mechanisms of acrolein (ACR) exposure. The results showed that ACR exposure shortened the lifespan of C. elegans, reduced reproductive capacity and locomotive behavior, and increased oxidative stress levels. ACR also affected the expression of antioxidant-related genes. The findings suggest that ACR exposure induces aging and oxidative stress in C. elegans, activating the DAF-16/FOXO pathway.

Summary: In this study, the toxicity of the herbicide atrazine and its main metabolites, deethylatrazine (DEA) and deisopropylatrazine (DIA), was compared using the in vivo model Caenorhabditis elegans. The results showed that DEA and DIA had lower toxicity on locomotion and reproduction compared to atrazine. Additionally, DEA and DIA induced less transgenerational toxicity on locomotion than atrazine and caused less oxidative stress and alteration in gene expression.

Summary: Surface functionalization and eco-corona formation can modulate the toxicity of nanoplastics, altering the potency and order of toxicity. The effects of surface charges on nanoplastic toxicity are primarily linked to differences in effect thresholds and dose-associated damage parameters, rather than toxicokinetic parameters. Eco-corona interactions between particles can reduce toxicity, but the order of potency of charged forms remains consistent.

Summary: MC-LR is an emerging environmental pollutant produced by cyanobacteria that poses a threat to wildlife and human health by damaging reproductive organs and causing trans-generational and developmental toxicity. The mechanisms of MC-LR-induced reproductive toxicity mainly include the inhibition of protein phosphatase activity and the induction of oxidative stress, with potential involvement of epigenetic modifications. Additional research is needed to further understand the estrogenic effects of MC-LR and its impact on reproductive health.

Summary: In this study, the toxic effects of fluopimomide on Caenorhabditis elegans and the possible mechanisms were evaluated. Results indicated that fluopimomide had negative effects on the growth, pharyngeal pumping, and antioxidant systems of C. elegans. Furthermore, it was found that oxidative stress and mitochondrial damage may be involved in the toxicity of fluopimomide.

Summary: The complex formed by the adsorption of classic toxins onto nanomaterials may exhibit stronger toxic effects than the individual materials. The surface adsorption effects mediated by nanomaterials can impact the bioavailability, toxicokinetics, distribution, and biological effects of classic toxins. This discovery is of great significance for the assessment of nanotoxicity.

Summary: The study investigated the single and mixture toxic effects of MC-LR and Phe mixtures on aquatic organisms, with results showing that the mixture toxicity was concentration-dependent and exhibited synergistic effects at low concentrations. The protective effects of high concentrations of MC-LR may lead to antagonistic effects. Furthermore, exposure to low concentrations of the mixture had a greater toxic effect on D. magna than either chemical alone.

Summary: The objective of this study was to determine the effect and the mechanism of subchronic MC-LR toxicity on preexisting diet-induced colorectal damage. The results showed that MC-LR may cause colorectal inflammation and barrier disruption by stimulating the Raf/ERK signaling pathway. The study suggests that MC-LR treatment may exacerbate the colorectal toxicity caused by an HFD.

Summary: The accumulation of nanoplastics exacerbates the toxic effects of microcystin on the liver of zebrafish, leading to cellular damage and oxidative stress. The presence of nanoplastics enhances the bioavailability of microcystin in the liver and alters the levels of reactive oxygen species, malondialdehyde, glutathione, and catalase, exacerbating the oxidative stress response.
