Metal-organic framework-based hybrids (MOFzyme) have promising applications in colorimetric aptasensors due to their highly efficient and stable catalytic activity. However, their efficient application in biosensors remains a challenging issue due to the limited reaction site and amorphous structure. Herein, we encapsulated catalase inside MOF cavities to prepare an MOFzyme with many functional groups on its surface, and the functional groups were utilized for the subsequent integration of MOFzyme into the hyaluronic acid-DNA hydrogel.

In 2023, European Food Safety Authority (EFSA) published a re-evaluation of the safety of bisphenol A (BPA), establishing the new tolerable daily intake (TDI) as 0.2 ng/kg·bw/day with a 20,000-fold reduction compared to 2015, which regained public concern about the impact of bisphenols (BPs) on human health. In order to explore the health risk to thyroid function of BPs, in this study, we assessed the internal exposure levels of BPs and the relationships between urinary BPs and thyroid function in general adults.

In recent years, increasing evidence has supported that high-fat diet (HFD) can induce the chronic, low-grade neuroinflammation in the brain, which is closely associated with the impairment of cognitive function. As the key organelles responsible for energy metabolism in the cell, mitochondria are believed to involved in the pathogenesis of a variety of neurological disorders. This review summarizes the current progress in the field of the relationship between HFD exposure and neurodegenerative diseases, and outline the major routines of HFD induced neuroinflammation and its pathological significance in the pathogenesis of neurodegenerative diseases.

To investigate the relationship of several adiposity-related anthropometric parameters, including BMI, waist circumference (WC), waist-to-hip ratio (WHR), body fat percentage (BFP) and indoles in plasma with the incidence of atherosclerotic cardiovascular disease (ASCVD) in adults in China. In China Kadoorie Biobank (CKB) study, blood samples were collected from 2 183 participants in the first resurvey in 2008 to detect indoles. Participants' body weight, body height, WC, hip circumference, and BFP were measured at baseline survey in 2004 and resurvey in 2008, the BMI and WHR were calculated with standardized methods.

Matrix effects pose a significant challenge in food analysis for the quantitative analysis of complex food samples. Herein, a novel magnetic covalent organic framework nanocomposite and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction-based stable isotope labeling (SIL) method were presented for highly selective and sensitive detection of steroid hormones in food samples using HPLC-MS/MS. The nanocomposite, FeO@TAPB-COF, with a core-shell structure exhibited high adsorption capacities for steroid hormones.

This study investigated the difference in survival among Listeria monocytogenes (LM) 10403S (highly pathogenic strain) and M7 (low pathogenic strain) in sausage under a simulated digestive environment, and established intestinal organoids and macrophages co-culture model to further explore the virulence expression difference to intestinal cells between LM 10403S and M7 after in vitro gastrointestinal digestion. Results showed that, compared with LM M7, LM 10403S exhibited a high survival rate during in vitro digestion, which may be due to the increased expression of stress response-related genes. In addition, the expression of virulence genes in LM 10403S was significantly higher than in LM M7 under the gastrointestinal environment.

Flame retardant polybrominated diphenyl ethers (PBDEs) accumulate in human bodies through food and dust ingestion, and cause neurobehavioral deficits with obscure mechanism. We aimed to investigate NMDAR-CaMKⅡγ-mediated synapse-to-nuclear communication involved in BDE-209-induced cognitive impairment, and alleviation from exogenous melatonin. Decreased NMDAR subunits GluN2A and 2B, autophosphorylation of CaMKⅡα, and postsynaptic GluA1 trafficking were observed in the hippocampus of juvenile rats after maternal BDE-209 exposure.

Unlabelled: Mixed-mode sorbents exhibit two or more primary retention mechanisms, which can enhance the selectivity and capacity of the extraction process in a single step. In this study, a facile approach was proposed to prepare functionalized metal-organic frameworks (MOFs) by post-synthetic oxidation. The composites could be varied independently for each processing step, resulting in four frameworks to meet different sample pretreatment requirements.
