Article Abstract
Coix seed, a versatile agricultural product, is known for its nutritional and functional components. However, the common contamination with mycotoxins represents a potential risk for human health. A sensitive analytical method was developed and validated to simultaneously determine 26 mycotoxins, including regulated and emerging, using stable-isotope-dilution-assay and LC-MS/MS. The study found co-contamination in 100% of samples from Southeast China, with 8-15 different mycotoxins for each and a total of 20 for all. Probabilistic risk assessments indicated long-term health concerns, with Aflatoxin B, ochratoxin A, and zearalenone being priority for risk control. Overall, this study appears to be the first to develop a rapid and robust analytical method of 26 mycotoxins and to conduct Monte Carlo simulation-based chronic risk assessments for 12 individual mycotoxins detected in coix seed, which would be of significance for risk communication as well as for regulatory authority in devising effective strategies to minimize exposure health risk.

The development of synthetically-useful biocatalysts requires characterizing the behavior of an enzyme under conditions amenable to preparative-scale reactions. Whole cells harboring the catalyst of interest are often used in such reactions, as protein purification is laborious and expensive. However, monitoring reaction rates when using whole cells is challenging, as cellular debris precludes the use of a continuous assay.

Background: Recent research has started to uncover an important connection between immune system activity and cognitive abilities. Although correlative associations have been documented, the causal mechanisms connecting specific immune cell subpopulations to cognitive capabilities remain insufficiently characterized. Our research aimed to determine directional relationships between distinct immune cell subtypes and cognitive function, potentially identifying targets for immunomodulatory interventions.

Background: Limited evidence exists regarding the cognitive and physical improvement effects of medium-chain triglyceride (MCT) intake in patients with stroke. This study aimed to investigate the association between MCT-enhanced rice consumption and enhancements in outcomes, including cognitive level, in patients following stroke.
Methods: We performed a retrospective cohort study on adults admitted to a rehabilitation center with cognitive decline following acute stroke.

The increasing use of engineered nanoparticles (NPs) in consumer and biomedical products has raised concern over their potential accumulation, transformation, and toxicity in biological systems. Accurate analytical methods are essential to detect, characterize, and quantify NPs in complex biological matrices. Inductively coupled plasma mass spectrometry (ICP-MS) has emerged as a leading technique due to its high sensitivity, elemental selectivity, and quantitative capabilities.

The laboratory analysis of new psychoactive substances and related drugs is crucial for accurate clinical and forensic diagnosis of poisonings. Given this, a new LC-MS/MS method for analyzing hallucinogens, synthetic cathinones, and synthetic cannabinoids in urine was developed. Urine samples were extracted using a liquid-liquid extraction protocol optimized via a multivariate experimental design.
