A total of 160 male C57BL/6J mice were fed with high-fat diet for 8 weeks to construct obese mice model.

Changes were also observed in colonic and liver transcript and metabolites, which were mainly enriched in glycolipid metabolism, ameliorated immune function, and mitigated inflammatory signals, autophagy, bile acid metabolism, and insulin resistance. <i>Akkermansia</i> and <i>Solibacillus</i> were significantly associated with changes in colonic metabolites and transcriptome genes. The liver bile component and glucose metabolites were significantly correlated with transcriptional gene expression in the aforementioned differential pathways.

Therefore, the present review aims to summarize advances in utilizing CRP for the prevention and controlling of inflammation under various pathological conditions. In particular, this review provides a comprehensive overview of the bioactive compounds present in CRP, with a specific focus on polymethoxyflavones and their transformations during aging process. Moreover, the underlying mechanism responsible for the anti-inflammatory effects primarily involves the inhibition of inflammatory factors through signaling pathways, such as mitogen-activated protein kinases and nuclear factor-erythroid 2-related factor 2–antioxidant pathways. The interaction with gut microbiota also contributes to the anti-inflammatory potential of CRP.

The complex compositions of flavors potentially induce severer toxicity especially in children. In this study, zebrafish embryos are applied for toxicity screening of flavor and its compounds by immersing in flavor solutions followed by the assessment of morphology of zebrafish larvae. Geraniol is identified as the prominent toxic compound and is considered highly toxic to zebrafish embryo. In further toxicology study, geraniol demonstrates the concentration-dependent developmental toxicity as the obvious reduction of body and eye lengths, as well as the increased prevalence of tail deformities, pericardial edema, and spine deformation. Zebrafish larvae treated with geraniol exhibit reduction in liver area and exocrine pancreas length, increase in yolk sac area, as well as elevation of triglycerides and total cholesterol, which indicate the inhibited nutrient utilization. Transcriptome analysis reveals that under geraniol treatment, 248 differentially expressed genes (DEGs) are downregulated, whereas 23 DEGs are upregulated, and 110 DEGs are related to metabolic process. Biological processes of lipid metabolism, carbohydrate metabolism, protein hydrolysis, and transmembrane transport, including their involved functional genes, are all downregulated.

However, a significant amount of waste is caused by inferior fruits that are partly eliminated from the fresh fruit market and by-products produced during transportation, storage, and processing. With increasing focus on environmental sustainability and resource conservation, recycling waste resources from tropical fruits has emerged as a hot topic of interest. Fruit-derived starch is an emerging approach to adding value for some tropical fruit waste and inferior fruits. This review article briefly overviews extraction methods, chemical composition, structural characteristics, physical and chemical properties, physiological benefits, modification techniques, and potential applications of new tropical fruit-derived starch. Compared with traditional starch, tropical fruit-derived starch exhibits unique structural and processing attributes, making it suitable as a supplement or replacement for industrial starch in the food industry. Moreover, tropical fruit-derived starch retains the rich nutrients and functional components present in fruits to some extent, thereby offering potential health benefits and greater consumer acceptance.

Methods including PacBio sequencing, HPLC, histological observation, western blotting, and RT-qPCR were jointly applied. The results indicated that the 20-day intake of real meat and plant-based meat analogs did not induce pathological changes in the colon of mice. However, when the feeding period was extended to 68 days, inflammatory infiltration was observed in the colon tissue of mice fed plant-based meat analogs. In contrast, the intake of real meat for 68 days performed better in maintaining colonic barrier function by reducing cell apoptosis, increasing the number of goblet cells and mucin secretion, and upregulating the expression of tight junction proteins. High-throughput sequencing revealed that the intake of real meat significantly altered the composition of the gut microbiota, reducing pro-inflammatory bacteria (such as <i>Bacteroides</i>, <i>Desulfovibrio</i>, or <i>Colidextribacter</i>) or pathogenic bacteria (such as <i>Mucispirillum</i> and <i>Helicobacter</i>) while increasing beneficial bacteria (such as <i>Lactobacillus</i>, <i>Bifidobacterium</i>, or <i>Roseburia</i>). Additionally, the consumption of real meat markedly decreased protein fermentation in the colon, leading to lower levels of cadaverine, putrescine, and spermine. These changes associated with real meat consumption reduced the activation of the pro-inflammatory pathway (lipopolysaccharide/Toll-like receptor 4/nuclear factor kappa B), ultimately maintaining colonic homeostasis in mice.

Proteomics analysis further showed that FA reduced HG-induced cell migration. Moreover, Western blot analysis verified that FA mitigated HG-induced apoptosis and cell migration via AMPK/FOXO pathway.

This study was first to examine the impact of egg whites on the frozen sturgeon surimi's gel properties from the perspective of inhibiting endogenous serine protease. The protease activity of egg whites group (CA + EW group, consisting of 4% egg whites and cryoprotectants) was 45.15% lower than that of cryoprotectants group (CA group, consisting of 3% sucrose, 3% sorbitol, and 0.3% sodium tripolyphosphate) at 12 weeks. From the results of inhibition kinetics, serine protease was inhibited by both anticompetitive and noncompetitive inhibition modes. Molecular docking analysis indicated that egg white achieves this inhibitory effect through ionic interactions and hydrogen bonding with serine protease. However, this inhibitory effect was absent when the freezing period was extended to 24 weeks. Compared with CA group, the CA + EW group exhibited 54.76% and 4.59% increase in gel strength and water-holding capacity, and 32.42% reduction in cooking loss after 24 weeks of freezing.
