Summary: This study investigated the metabolism, tissue distribution, and excretion of taxifolin in rats after oral administration of taxifolin encapsulated zein-caseinate nanoparticles (TZP). Isomerization of taxifolin was found in the rat's small intestine and colon. UPLC-QTOF-MS analysis identified 16 metabolites of taxifolin in rat feces, plasma, and urine. Taxifolin underwent hydration, dehydration, and ring fission metabolism in the colon through gut microflora. The main metabolites detected in plasma and urine were sulfated, glucuronidated, and/or methylated products of taxifolin. The dynamic variation of taxifolin and its metabolites in tissues and urine were quantified using UPLC-QqQ-MS/MS. Taxifolin and its metabolites were rapidly absorbed and distributed in tissues, with lower concentrations found in the heart and brain. Feces excretion of taxifolin was determined by HPLC, and the total excretion within 24 hours was 2.83 +/- 0.80% of the given dose, with the highest excretion occurring during 8-10 hours post administration. Compared to feces, the excretion of taxifolin and its metabolites in urine was much faster, with a total excretion of 1.96 +/- 0.23% within 12 hours.

Summary: This article mainly discusses the role of aryl hydrocarbon receptor (AhR) in aging and longevity, as well as several AhR ligands with potential anti-aging properties. The article suggests that AhR-driven expression of xenobiotic metabolism genes into old age may be a key mechanism through which moderate induction of AhR elicits positive benefits on longevity and healthspan. Additionally, the article shows that liver-specific AhR target genes are enriched among genes subject to epigenetic aging through integration of publicly available datasets. Hence, the interplay between AhR and epigenetic aging should be the subject of future research, and a broad range of non-toxic AhR ligands should be investigated for their potential to promote healthspan and longevity.

Summary: One hypothesis for age-related hearing loss is a decrease in ear metabolism, but the direct measurements are lacking. Using locusts as a model, the study found that auditory organ metabolism decreases with age, but there is no correlation with sound-evoked nerve activity. Manipulating the metabolism of the auditory organ through diet and cold-rearing did not affect sound-evoked nerve activity. The study suggests that age-related hearing loss is dominated by accumulative damage in multiple cell types and processes, surpassing the impact of metabolic decline.

Summary: This study investigated the effects of warmer temperature (26 degrees C) and mercury pollution (1 mu g/L) on the marine copepod Tigriopus japonicus across three generations (F0-F2). Phenotypic traits, mercury accumulation, and proteomic analysis were performed. The results showed that both warmer temperature and mercury exposure significantly impacted the phenotypic traits. Combined exposure increased mercury bioaccumulation and its toxicity in each generation. Proteomic analysis revealed that warmer temperature upregulated the determination of adult lifespan pathway but compromised fitness. Mercury pollution caused energy depletion and reduced defense performance, leading to decreased reproduction. Importantly, warmer temperature aggravated mercury toxicity by disrupting energy metabolism and impairing detoxification systems. This study provides a mechanistic understanding of T. japonicus response to coastal warming and mercury pollution.

Summary: Very few studies have examined the influence of fish on the degradation rate of microplastic particles. This study aimed to test the short-term effects of fish presence on water chemical parameters and the abundance and genetic diversity of bacteria colonizing microplastics. The presence of fish increased the concentration of certain chemicals in the water and the number of bacteria, which in turn led to an increase in the abundance and diversity of bacteria on the surface of microplastics.

Summary: In this study, the combined toxic effects of simultaneous exposure to microplastics and triclosan on Daphnia magna were investigated. It was found that simultaneous exposure resulted in increased mortality and altered antioxidant enzymatic activities compared to single exposure to triclosan. The accumulation of triclosan was also observed due to the inhibition of the multixenobiotic resistance activity by microplastics. These findings suggest the synergistic toxic effects of simultaneous exposure to microplastics and triclosan.

Summary: Despite limited understanding and analysis of the biological fate of nanoplastics, a novel stable carbon isotopic approach has been proposed to detect and quantify nano- and microplastics in complex organic matrices. By quantifying the contribution of plastic particles in the stable carbon isotopes composition in different tissues, tissue-specific bioaccumulation of nano- and microplastics in a fish species has been investigated. The findings shed light on the unique mode of action of nanoplastics' bioaccumulation based on physicochemical properties and have significance in improving our understanding of the tissue-specific bioaccumulation of nanoplastics in aquatic organisms.

Summary: The gut microbiome of Antarctic mackerel icefish was characterized using next-generation sequencing for the first time in this study. The microbial community composition of the intestinal wall samples was found to be different from other sample types, with a higher relative abundance of Photobacterium in the intestinal content and potential pathogens such as Escherichia, Shigella, and Pseudomonas in the intestinal wall. Unlike other marine fish species, Vibrio and Lactobacillus were nearly absent in the gut microbiome of the mackerel icefish. Functional gene profiling predicted higher relative abundance of nutrient degradation-related genes in the intestinal content and higher relative abundance of important metabolite biosynthesis-related genes, such as menaquinols, in the intestinal wall. The difference in microbial community structure between the intestinal wall and intestinal content supports niche separation and highlights the importance of collecting intestinal wall samples to understand the complete picture of the gut microbiome.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
