要旨

Pregnancy is a dynamic state involving rapid physiological changes in metabolism, affecting the health and development of the offspring. During pregnancy, the placenta constitutes a physical and immunological barrier to provide fetal nutrition through the maternal blood and prevent the exposure of the fetus to dangerous signals. Metabolic changes in the plasma, the fecal microbiota profile, and functional regulation in the placenta were studied in sows supplied with a ferrous–sucrose complex (FeSuc) from late gestation to parturition. The results revealed that maternal FeSuc supplementation enhanced arginine and proline metabolism, glutathione metabolism, with increased glutamic acid, beta-D-glucosamine, L-proline, 1-butylamine, and succinic acid and reduced sphingosine and chenodeoxycholic acid sulfate levels in the plasma. Moreover, significantly increased abundances of Christensenellaceae_R-7_group, Prevotellaceae_NK3B31_group, and Lachnospiraceae_NK4B4_group were detected in the feces of sows from the FeSuc group (P < 0.05). Spearman's correlation analysis indicated that Prevotellaceae_NK3B31_group abundances were positively correlated with glutamic acid, indoxyl sulfate, acetyl-DL-leucine, and beta-D-glucosamine, while Christensenellaceae_R-7_group was positively correlated with beta-D-glucosamine. Furthermore, maternal FeSuc supplementation significantly increased neonatal glucose (P < 0.01) and iron (P < 0.01) in the neonatal serum, significantly increased IL-10 and TGF-β1 levels in the neonatal liver (P < 0.01) and jejunum (P < 0.05), promoted the transcription of immune molecules in the placenta, and significantly increased the protein expressions of EGF (P < 0.05), PI3K (P < 0.01), p-PI3K (P < 0.001), p-AKT (P < 0.01), and glucose transporter 1 (GLUT1) (P < 0.001) in the placenta. The current study demonstrated that FeSuc supplementation regulated maternal metabolism processes by altering the fecal microbial composition and improved neonatal immunity and placental glucose transportation by activating the EGF/PI3K/AKT signaling pathways in sows.

Food & Function provides a unique venue for physicists, chemists, biochemists, nutritionists and other food scientists to publish novel, cutting-edge, original research focussing on food, its nutrients and their relation to human health and nutrition. We welcome research describing the: Physical properties and structure of food and how this relates to sensory perception and human health Biochemical and physiological actions of food components Interactions between foods, gut microbiota and human physiology Nutritional and biological evaluation of food Clinical and population studies using food or food components Development of biomarkers of food intake and effects on human health We also welcome systematic reviews and meta-analyses of existing studies in the literature, provided these are objective and scientifically valid Food in this context is defined as materials of plant, animal or mineral origin, which are consumed orally (by humans) for pleasure and to sustain growth and vital processes. Examples of research topics that are of interest to be published in Food & Function are: Chemistry and physics of food components and digestion processes Relationship between the physical properties/structure of food and nutrition and human health - for example, impact of food matrix or processing on nutrient release and uptake Molecular properties and physiological effects of food components (nutrients, fibres, essential micronutrients, phytochemicals, bioactives, food substitutes, novel ingredients, allergens, flavours and fragrances) Nutritional and health effects of food including bioavailability and metabolism assessment of food components (nutrients, micronutrients and other microconstituents) Efficacy and mechanisms of food constituents in the body - including biomarkers of intakes, exposure and effects Impacts of foods/food components on gut microorganisms and human physiology - For example impact of fermented foods Role of nutrition and diet in human disease prevention and development Cellular and molecular effects/mechanisms of food/food components image block The following types of research are not within the scope of Food & Function: Research relating to traditional herbal medicines, medicinal plants or active compounds extracted from such plants (materials that are primarily consumed as medicine, i.e. the intended purpose is primarily to treat, cure or prevent a non-deficiency disease) or relating to foods not recognised as human diet contributors Animal nutrition research that is not primarily designed as a model to benefit human nutrition (for example, studies of growth/accretion, heat stress, weaning, ruminant digestion, meat quality, etc.) Treatments administered by non-oral routes such as injection (subcutaneous, intramuscular, intraperitoneal, etc.), dermal/transdermal, rectal, inhalation, nasal, etc. Exceptions are when such routes of administration are used for mechanistic/control purposes in the experimental design Pharmacological/pharmaceutical approaches: Encapsulation, emulsification and/or pure controlled release of compounds or bioactives that do not come directly from edible foods, such as dietary supplements - these are better suited to a pharmaceutical journal In vitro or in vivo studies with poorly defined (insufficiently characterised) extracts and studies without appropriate controls will not be considered Cells studies not considering the metabolism of food components ingested – for example, irrelevant exposure of cells to compounds not present in the body after absorption Manuscripts with only a fully theoretical/bioinformatic approach and without appropriate support from analytical evidence will not be considered for publication Studies focussing solely on food engineering, preservation and sustainable technologies – these can be published in our companion journal Sustainable Food Technology Pure food analysis - these can be published in Analytical Methods
