內(nèi)容: The rising prevalence of food allergy is a global concern, especially as children are more susceptible to developing anaphylaxis than adults. Food-induced anaphylaxis, a severe and potentially life-threatening allergic reaction, imposes a healthcare burden in many Asian countries. While literature on food allergy in Asia is limited and heterogeneous, the prevalence shows an upward trend. In contrast, food allergy in developing countries is often overlooked as a health issue. China, with its vast population and landmass, is experiencing notable shifts in food allergy patterns. Unlike Western countries where tree nuts are common triggers, wheat, seafood, and fruits increasingly provoke allergic reactions among the Chinese population. Various diagnostic methods for food allergy were employed in China; however, the lack of a standardized approach presents challenges for effective management. In the future, it is essential to develop efficient and convenient detection methods while utilizing big data for extensive epidemiological investigations and clinical studies to address the complex health issue of food allergy.

內(nèi)容: The gut-brain axis (GBA) is a crucial connection that enables bidirectional communication between the central nervous system and gastrointestinal tract. Serotonin is a tryptophan (Trp) metabolite and an important gastrointestinal signaling molecule. Kynurenine and indole derivatives mediate the central nervous system, thereby affecting neurological diseases. The gut microbiota has direct or indirect impact on Trp metabolism. Different genera of gut microbiota affect Trp metabolites in different ways, thus changing the communication between the brain and gastrointestinal tract. This review highlights the triangular relationship between the GBA, Trp metabolism, and gut microbiota and summarizes the types of relevant gut microbiota genera involved in this triangular relationship. By modulating the gut microbiota through probiotics, dietary interventions, fecal microbiota transplantation, and other methods, improving Trp metabolism and thereby influencing metabolites provides potential targets for treating GBA-related diseases.

內(nèi)容: In this work, a magnetic molecularly imprinted polymer with good adsorption capacity and a 2-methylimidazole (MI)-Cu-guanosine 5’-monophosphoric acid (GMP) nanozyme with high catalysis activity were first synthesized. Then, using the imprinted polymer as biomimetic antibody and the MI-Cu-GMP nanozyme as label, a novel direct competitive biomimetic enzyme-linked immunoassay (BELISA) method was established for the sensitive detection of acrylamide in foods. Under optimal conditions, the limit of detection (LOD, IC15) and sensitivity (IC50) of the BELISA method towards acrylamide were 0.02 and 4.52 mg/L, respectively. The BELISA method was successfully applied for acrylamide detection in spike potato crisp samples, with recoveries ranging from 87.50% to 106.67% being obtained. Further, the levels of acrylamide in coffee, fried dough twists and biscuit samples were determined by the BELISA and high performance liquid chromatography, with no significant difference found between the results of the two methods. This work thus introduces a novel, fast and accurate method for acrylamide detection in foods.

內(nèi)容: Platelet apoptosis is crucial for initiating atherothrombosis and is primarily induced by circulating oxidized lipids in oxidized low-density lipoprotein (ox-LDL) particles under hyperlipidemic conditions. Panax notoginseng has excellent medicinal and food dual-use characteristics. P. notoginseng saponins (PNS), the primary active ingredients extracted from the roots of P. notoginseng, are widely used as nutritional supplements owing to their multiple health benefits. In this study, we investigated the efficacy of PNS in platelet apoptosis under hyperlipidemic conditions in vitro and in vivo. In vitro assays demonstrated that PNS attenuated platelet mitochondrial dysfunction (loss of mitochondrial membrane potential) and subsequent apoptosis (caspase-9/-3 activation and phosphatidylserine exposure) in ox-LDL-stimulated human platelets. Mechanistically, PNS activated cAMP/PKA signaling, leading to decreased NOX2-mediated oxidative stress, and the resultant inhibition of platelet apoptosis. Moreover, 12-week supplementation of PNS (0.02% diet) in hyperlipidemic C57BL/6J mice also significantly alleviated platelet mitochondrial dysfunction and apoptosis in vivo. Studies using pharmacological inhibitors of PKA and NOX2 demonstrated that the efficacy of PNS on platelet dysfunction in mice was primarily modulated by the up-regulation of cAMP/PKA signaling and the resultant inhibition of NOX2-dependent oxidative stress. Thus, these results suggest that PNS attenuate oxidative stress-mediated platelet apoptosis under hyperlipidemic conditions by up-regulating the cAMP/PKA signaling pathway in vitro and in vivo. Our study elucidated a possible novel strategy of involving the use of PNS to prevent atherothrombosis in hyperlipidemia.
