In this study, a novel imidazolium-based ionic liquid (IL) coating was developed for stir bar sorptive extraction (SBSE) using a sol-gel method. The effects of different counterions, conditioning temperatures and polymer compositions were investigated. The stir bar with bis((trifluoromethyl)sulfonyl) amide 1-butyl-3-(3-(triethoxysilyl)propyl)-1H-imidazol-3-ium showed good mechanical and thermal stability with high resistance to water solubilization.

Small-for-Size Syndrome (SFSS) remains a critical challenge in living donor liver transplantation (LDLT), characterized by graft insufficiency due to inadequate liver volume, leading to significant postoperative morbidity and mortality. As the global adoption of LDLT increases, the ability to predict and manage SFSS has become paramount in optimizing recipient outcomes. This review provides a comprehensive examination of the pathophysiology, risk factors, and strategies for managing SFSS across the pre-, intra-, and postoperative phases.

Advanced suspect and non-target screening (SNTS) approach can identify a large number of potential hazardous micropollutants in groundwater, underscoring the need for pinpointing priority pollutants among detected chemicals. This present study therefore demonstrates a novel multi-criteria decision making (MCDM) framework utilizing machine learning (ML) algorithms coupled with toxicological prioritization index tool (i.e.

Ingestive uptake is critical for understanding the accumulation and trophic transfer of chemicals and synthesized particles in general. This study explored the contribution of ingestion in the bioaccumulation of chemicals focusing on worms. Novel theory and equations were developed to derive fractional ingestive contribution, f, from a broad range of dietary uptake and accumulation studies, and to build a small dataset of f (n = 43) from relevant toxicokinetic and bioaccumulation measurements.

Article Synopsis
- Tire additives known as benzothiazole (BTs) are emitted into agricultural environments, and their uptake and metabolism in food crops, particularly in carrots, were evaluated to understand their behavior.
- Carrot plants readily absorbed BTs through their roots, but the upward movement to leaves was limited, with variations in translocation efficiency based on the specific BT structure.
- High-resolution mass spectrometry identified 18 novel BT metabolites in carrots, highlighting that transformation mainly occurs through glycosylation and amino acid conjugation, leading to structure-specific metabolic processes.
