Summary: This study investigated the effects of sub-toxic concentrations of functionalized selenium nanoparticles on prostate cancer cells and their intracellular localization and fate. The results showed that monodisperse selenium nanoparticles capped with bovine serum albumin could slow down the migration capacity of aggressive prostate cancer cells compared to polydisperse selenium nanoparticles capped with chitosan. The nanoparticles were found to interact with mitochondria in the cells. These findings provide new insight for further research on the cytotoxic mechanisms of selenium nanoparticles.

Summary: Research on earthworms exposed to silver-contaminated soil revealed that different forms of silver had varying effects on survival, but exhibited similar speciation and content in the earthworms at the end of exposure, indicating biotransformation. X-ray micro-computed tomography images showed silver preferentially accumulated in specific tissues, suggesting efficient bioaccumulation with a regulatory mechanism in E. fetida. The competition between silver and copper, along with the speciation of internal silver, indicates a link to thiol-rich proteins like metallothioneins involved in metal sequestration and detoxification.

Summary: This study examined structural changes in subchondral bone samples from osteoarthritic knee patients compared to controlled patients, using Synchrotron-based X-ray fluorescence and X-ray absorption spectroscopy techniques. The results revealed lower phosphorus content in older OA patients, leading to lower Ca-P proportions associated with osteoporosis. The majority of bone samples exhibited an amorphous structure of calcium-phosphate.

Summary: Water electrolysis for hydrogen production provides a convenient and carbon-free option to regulate the intermittency of renewable energy sources. Efficient catalysts based on noble metals are currently used for large-scale production, but efforts are being made to reduce catalyst usage while maintaining their efficiency. Fundamental studies on catalyst structure, reaction intermediates, and failure modes support these efforts. Synchrotron-based techniques, such as X-ray photoelectron and X-ray absorption spectroscopies, can provide valuable information during the reaction. This article gives an overview of these techniques and their application to water electrolysis.

Summary: Turpentine wood is known for its resistance to marine borers, believed to be due to its high silica content and presence of unknown compounds. Recent studies have revealed a diverse range of biocidal heavy metals in its heartwood, with concentrations reaching toxic levels for mollusk embryos and larvae. These inorganic components may contribute to the wood's marine borer resistance.

Summary: Pollutants released from pharmaceutical, steel, paper, and battery industries into water cause irreparable damage to the biotic system by entering the natural ecosystems and human food chain. Monitoring and determining heavy metal levels in water are crucial for human beings. In this study, TXRF spectrometry technique was used to assess the contaminant levels in water samples from an industrial area. The elemental concentrations were compared to the guidelines from WHO and BIS, and water quality parameters were assessed. The results showed that some water samples were unfit for drinking with high levels of lead and other heavy metals.

Summary: Antifouling paints incorporate biocides to prevent the growth of unwanted organisms, but these biocides also impact non-target organisms and ecosystems. This study examined the occurrence and concentrations of biocides in antifouling paint formulations worldwide. The results identified 25 active ingredients currently used, with cuprous oxide, copper pyrithione, zinc pyrithione, zineb, DCOIT, and cuprous thiocyanate being the most frequent ones.

Summary: The study found that even at the lowest dose tested (0.35 μg g(-1)), chlorothalonil showed genotoxic and mutagenic effects, which increased in a dose-dependent manner with higher doses. This evidence suggests that the compound should be banned due to potential hazards to aquatic ecosystems and human health, outweighing any benefits to food production.

Summary: Thyroid hormones play a critical role in regulating biological processes, and determination of deiodinated TH metabolites in key organs can help understand tissue-specific TH metabolism and homeostasis. A highly sensitive method was developed to determine six THs in dog brain and liver, which was successfully applied to analyze THs in dogs exposed to PCBs and revealed alterations in peripheral TH metabolism caused by environmental pollutants.

Summary: Estuarine saltmarshes in South America are affected by chemical and petrochemical industries, resulting in the presence of non-essential trace elements (NTEs) and polycyclic aromatic hydrocarbons (PAHs) in sediments. The native cordgrass Spartina densiflora exhibits different responses to pollution in different saltmarsh areas, with the ability to increase NTEs levels in rhizosediments and bioconcentrate Cd in roots. However, general translocation of contaminants is not observed. Conversely, PAHs contents are higher in cordgrass tissues, bulk sediments, and rhizosediments, with lower levels in rhizosediments compared to bulk sediments. The study highlights the capacity of S. densiflora to retain, remove, and/or translocate priority contaminants depending on their chemical characteristics and the level of contamination.

Summary: The study assessed the potential health risk of ingesting organotin compounds in seafood from the Yucatan Peninsula. Organotin compounds were detected in all samples, but the estimated intake levels were below the tolerable daily intake established by EFSA. Therefore, seafood consumers in the Yucatan Peninsula are unlikely to be at risk.

Summary: We characterized the bacterial and fungal communities in forest soils using CLPP and PCR-DGGE analysis. The results showed clear separation between the O and A horizons in terms of CLPP and DGGE profiles, except for the fungal CLPP. No significant links were observed between the O and A horizons, suggesting different factors influencing the microbial communities. However, there were significant couplings between bacterial and fungal profiles within each horizon, indicating common factors shaping the communities. The potential functioning was not strongly associated with the composition of the microbial community.

Summary: The addition of phosphorus has minimal effect on enhancing the mineralization of preexisting soil organic carbon. However, in phosphorus-limited tropical forest soils with nitrogen-fixing trees, the microbial phosphorus mining can drive positive priming effects when a small amount of glucose is added. The results indicate that positive priming effects occur through microbial phosphorus mining, independent of phosphatase hydrolysis of organic phosphorus esters, under phosphorus limitation in nitrogen-rich and phosphorus-poor tropical forest soils.

Summary: Converting natural forests to coniferous plantations in temperate regions impacts soil nitrogen cycling, but the belowground microbial communities responsible for these changes are poorly understood, especially in coniferous-dominated forest ecosystems. In this study, we examined the effects of converting natural forests to pure cedar plantations on soil N cycling and microbial communities using high-throughput amplicon sequencing technique in two areas with different acidity levels. Our results showed that the conversion increased inorganic N content and altered the relative abundances of fungal and bacterial communities, as well as their interactions with ammoniaoxidizing archaeal abundances, leading to higher nitrate N content in cedar plantations, particularly in less acidic areas.
