Abstract Young children are attracted to flavored foods with enhancers, particularly monosodium glutamate (MSG). Experimental studies have proven that MSG can alter the hypothalamic–pituitary–adrenal (HPA) axis response in neonates. We, therefore, investigated modulation of microRNAs (miRNAs) by dietary and its association stimulation HPA inflammatory young male rats. One-month-old rats were fed chow enriched (3 g/kg) for 16 weeks. Feeding markedly up-regulated hypothalamic miR-218, Toll-like receptors-4, nuclear factor-kB but down-regulated miR-155 glucocorticoid receptors (GR). In addition, it triggered a remarkable elevation adrenocortical lipid peroxidation depletion antioxidants. These changes coupled increased plasma levels hormones, comprising corticotropin-releasing hormone, adrenocorticotropic corticosterone levels, serum pro-inflammatory cytokines. Taken together, current findings indicated caused an activation axis, down-regulation GRs, systemic response. disturbances associated modulating miRNAs, encompassing miR-218 155.

Abstract The increasing prevalence of multidrug-resistant pathogens is a critical public health issue, necessitating the development alternative antibacterial agents. Examples these are methicillin-resistant Staphylococcus aureus (MRSA) and emergence “pan-resistant” Gram-negative strains, such as Pseudomonas aeruginosa Acinetobacter baumannii , which occurred more recently. This review examines various emerging materials with significant activities. Among nanomaterials quantum dots, carbon metal–organic frameworks (MOFs), covalent organic (COFs), layered double hydroxides, all demonstrate excellent properties. Interestingly, including agents within structure can help avoid bacterial resistance improve long-term efficacy materials. Additionally, potential liquid solvents, ionic liquids both deep eutectic solvents natural explored. discusses synthesis methods, advantages, new By providing comprehensive overview innovative materials, this aims to contribute ongoing search for effective solutions combat antibiotic resistance. Key studies demonstrating effects against like Escherichia coli strains summarized. MOFs have exhibited properties through controlled ion release surface interactions. COFs enhanced encapsulated antibiotics displayed intrinsic activity. Other nanomaterials, generated reactive oxygen species, leading microbial inactivation. provide insights into classes highlight them addressing global crisis points • Nanomaterials show strong drug-resistant bacteria Emerging offer novel enhance efficacy, showing promise in combating

ABSTRACT Capillary electrophoresis (CE) is a powerful analysis technique with advantages such as high separation efficiency resolution factors above 1.5, low sample consumption of less than 10 µL, cost‐effectiveness, and eco‐friendliness reduced solvent use lower operational costs. However, CE also faces limitations, including limited detection sensitivity for low‐concentration samples interference from complex biological matrices. Prior to performing CE, it common utilize preparation procedures solid‐phase microextraction (SPME) liquid‐phase (LPME) in order improve the selectivity analysis. Recently, there have been advancements development novel materials that potential greatly enhance performance SPME LPME. This review examines various their uses when combined CE. These include carbon nanotubes, covalent organic frameworks, metal–organic graphene its derivatives, molecularly imprinted polymers, layered double hydroxides, ionic liquids, deep eutectic solvents. The utilization these innovative extraction methods being examined. Analyte recoveries limits attained range matrices are used assess effects on selectivity, sensitivity, efficiency. Exploring new techniques important enables researchers address current limitations has efficiency, thereby improving
