Summary: Rare earth elements (REEs) are essential in many industrial and medical fields due to their unique properties, but they are also becoming emerging pollutants. This study investigated REE bioaccumulation in Anguilla anguilla from the Loire estuary, revealing differences in organotropism between life stages and genders. Significant variations in REEs abundances were observed in different organs, life stages, and genders, with parasitism by Anguillicola crassus also appearing to impact REE bioaccumulation.

Summary: This study investigated the ability of blood transcriptional profiling to identify the salinity-habitat histories of European eels. By comparing gene expression in the blood of eels collected from different locations, the researchers were able to classify eels with different habitat histories. This non-lethal approach shows promise as a replacement for lethal otolith microchemistry analysis.

Summary: Artificial light at night (ALAN) is a pervasive form of environmental pollution that can negatively impact the critically endangered European eel. This study found that European eels exposed to high levels of ALAN were more likely to reject illuminated routes, less likely to choose illuminated channels when given a choice, and moved downstream more rapidly when selecting the illuminated route. These findings provide a basis for future research and highlight the ecological impacts of ALAN as a significant environmental pollutant.

Summary: The study shows that European eel elvers can adapt well to biofloc systems, which have lower production costs compared to conventional systems. The maintenance of biofloc in tanks and prevention of opportunistic pathogens were identified as critical issues. Further studies are needed to test the technology with older eel stages.

Summary: Eels use their swimbladder for buoyancy control, which is achieved through the activity of gas gland cells and countercurrent concentration. Gas gland cells produce lactic acid and CO2, which acidify the blood and release oxygen from hemoglobin. The diffusion of oxygen and CO2 into the swimbladder is facilitated by the diffusion gradients created by elevated PO2 and PCO2. Infection of the swimbladder with the nematode Anguillicola crassus impairs its function as a buoyancy organ.

Summary: The anthropogenic impact on the aquatic environment of the Rasa River in Croatia was investigated. The study used yellow European eel as a biological indicator to analyze PBDEs, PCBs, DDT isomers, and major and trace elements. The results showed generally low contamination levels in the surrounding area, with organic contaminants increasing in muscle with lipid content, length, weight, and body condition. Metal(loid) levels decreased or remained unchanged with increasing size, except for a few elements that accumulated in the liver at the downstream location.

Summary: The effects of eel-specific recombinant gonadotropins (rGTHs) on oocyte development in European eels were tested in this study. The results showed that treatment with recombinant luteinizing hormone (rLH) induced oocyte development in vitro, and treatment with recombinant follicle-stimulating hormone (rFSH) followed by rLH stimulated sexual maturation in vivo. Larvae were produced for the first time by rGTH treatment alone, but further optimization is needed for dosage and timing.

Summary: This study investigated the molecular mechanisms and immune response in the skin mucus of Anguilla anguilla infected with Anguillid herpesvirus 1 (AngHV) at the protein levels. TMT-labelled proteomics with LC-MS/MS was used for quantitative identification of proteins. The results showed significant changes in protein expression, and many differentially expressed proteins were found to be enriched in various pathways, providing important insights into the pathogenesis of AngHV.

Summary: This article discusses the life cycle strategies of anguillid eels and introduces methods for studying these strategies. The article points out that the current management framework for eels focuses mainly on freshwater environments, ignoring eels growing in saline waters. The authors argue that the ability of eels to shift habitats is crucial for the recovery of endangered species.

Summary: Polybrominated diphenyl ethers (PBDEs) are widely used flame retardants found in various materials. They have been detected in soil, air, water, dust, and animal tissues, and are associated with a range of toxic effects on different organ systems. Understanding the mechanisms and potential toxicity of PBDEs is important for developing effective prevention strategies.

Summary: The study found that prenatal exposure to background levels of PBDEs, especially BDE-47, was associated with lower IQ scores in boys, but not in girls. This suggests that exposure to PBDEs during early development may have a sex-dependent and detrimental effect on a child's neurodevelopmental trajectory.

Summary: Per- and polyfluoroalkyl substances (PFAS) are widely present in aquatic environments. The occurrence and fate of emerging PFAS require new data. A field study in the Seine River basin revealed that factors such as age, sex, and trophic ecology influence the bioaccumulation of PFAS in fish. The study also found that fish caught upstream had lower PFAS contamination compared to those caught downstream, with urban and industrial inputs being major contributors. Furthermore, the variability of PFAS levels in fish was influenced by both diet and trophic level.

Summary: Unidentified per- and polyfluoroalkyl substances (PFAS) are commonly found in aquatic environments, and this study aimed to estimate their contribution using the total oxidizable precursor (TOP) assay. An optimized extraction method was developed to examine the distribution of targeted PFAS in French surface sediments, and the results showed that unattributed PFAS were more abundant in industrial and urban areas, with strong correlations to targeted compounds.

Summary: Enzymes play a crucial role as biological catalysts in accelerating biochemical reactions in living organisms. This study proposes a convenient method for monitoring enzymatic catalytic processes using native top-down mass spectrometry. By exploring the heterogeneity of the chymotrypsin sample and using tandem mass spectrometry, the researchers were able to monitor covalent and noncovalent enzymatic complexes, substrates, and products during catalysis. The results demonstrate that this method has the potential to be a promising tool for characterizing biocatalysts.

Summary: This study presents a method for constructing wearable sweat electrolyte sensors using carbon fiber-based solid-contact ion-selective electrodes (SC-ISEs). By using carbon fibers extracted from commercial cloth as electrode material, the cost and reproducibility issues of flexible SC-ISEs were addressed. The results showed that the carbon fiber-based SC-ISEs exhibited reversible voltammetric and stable impedance performances, and had high reproducibility of standard potentials between normal and bending states.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: The study developed a split aptamer-based sandwich-type ratiometric biosensor for the detection of 17 beta-estradiol (E2) using photoelectrochemical and electrochemical assays. The biosensor utilized split aptamer fragments to recognize E2 and trigger a hybridization chain reaction, resulting in the production of double-stranded DNA labeled with CdTe quantum dots. This DNA complex was able to sensitize CdTe quantum dots and generate response signals for E2 detection. The developed biosensor demonstrated high sensitivity and accuracy with two linear ranges and low detection limits.
