A non-targeted UHPLC-HRMS metabolomics approach combined with chemometric anal. was employed to assess the change in metabolite profiles of sorghum flakes based on food processing techniques.The result showed that fatty acids were the most abundant metabolites, followed by lipids, amino acids, alkaloids, amines, and polyphenols, representing key metabolic markers influenced by food processing in sorghum flakes.Specific metabolites, including 15S-Hydroxyeicosatrienoic acid (15S-HETrE), terminaline, vitamin E acetate, furan fatty acid F6, all-trans-retinal, and fingolimod, exhibited increased concentrations during oven processing compared to raw sorghum, likely due to their thermal stability.This study provides valuable insights into effect of food processing effect on metabolites profiles.

Maternal exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with offspring adiposity; however, underlying mechanisms remain unclear. In this study, we quantified 11 PFAS in maternal plasma collected between 12 and 16 gestational weeks and 104 lipid metabolites in the cord blood of 525 mother-infant pairs. Principal components of multiple PFAS compounds, extracted by principal component analysis, were employed to investigate the effect of the PFAS mixture. Infant anthropometric indicators included weight, length, waist/arm circumference, and abdominal/triceps/subscapular skinfold thickness at birth and 6 and 12 months old. Multiple linear regression showed that maternal PFAS exposure was primarily associated with increased glycerophospholipids and decreased fatty acyls and bile acids in cord blood. Four glycerophospholipids (16:0 PI, 16:0-18:1 PI, 18:0-20:4 PI, and 18:0-18:1 PS), fatty acyls (5(S)-HETE, 15(S)-HETE, 13-HDoHE, and dhkPGF2), and bile acids (GCA, TCA, TCDA, and TDCA) partially mediated the positive associations of the first principle component of PFAS compounds (with positive loadings for all PFAS compounds), PFNA, and PFUdA with infant skinfold thickness with mediating proportions ranging from 15.24% to 33.39%. Our findings provide novel insights into mechanisms underlying the effects of maternal PFAS exposure on infant growth.

Perimenopausal depression is often accompanied by metabolic disorders, which have long-term harmful effects on women's physical and mental health. Quercetin, a kind of phytoestrogen, has anti-inflammatory, antioxidant, and nerve-protective effects, and can regulate various metabolic disorders. This study aims to investigate the effect of quercetin on hippocampal metabolic disorder in perimenopausal depression rat models based on untargeted metabolomics technology. The rat model of perimenopausal depression was established by ovariectomy combined with chronic unpredictable mild stress (OVX-CUMS). Rats with no difference in sucrose preference were randomly divided into four groups (n = 12): sham group, OVX-CUMS group (model group), model plus quercetin group, and model plus 17β-estradiol group. At the end of the experiment, hippocampal tissues were collected for untargeted metabolomics analysis, morphological analysis, and detection of related indicators. Metabolomics identified 23 differential metabolites in the model group, and the pathway analysis discovered hippocampus metabolic abnormalities including the metabolism of arachidonic acid metabolism, glycerophospholipid metabolism, and ubiquinone biosynthesis, accompanied by an increase in oxidative stress, inflammation, and lipid peroxidation indicators. At the same time, the morphological characteristics of ferroptosis occurred in the hippocampus in the model group. These abnormal changes were reversed by treatment with quercetin or 17β-estradiol. Quercetin can improve perimenopausal depression by regulating hippocampal metabolic disorders and reducing hippocampal ferroptosis in rats. These findings provide a new strategy for the use of quercetin in the prevention and treatment of perimenopausal depression.
