ABSTRACT: Supplementation with Silybum marianum Extract, Synbiotics, Omega-3 Fatty Acids, Vitamins, and Minerals: Impact on Biochemical Markers and Fecal Microbiome in Overweight Dogs
Project description:The goal of this study is to find out the exact mechanisms of action of silymarin (SM), a complex mixture of flavonolignans structures isolated from milk thistle (Silybum marianum), on the biological behavior (phenotype) of human HaCaT keratinocytes.
Project description:Synbiotics are a combination of probiotics and prebiotics which can alter the composition of the gastrointestinal tract evoking beneficial effects throughout the body through the production of a battery of bioactive metabolites. In this study, a synbiotic was used to reduce the behavioral and biochemical symptoms of depression and this nanostring panel was used to decipher where along the gut-brain-axis the synbiotic-derived metabolites were invoking their beneficial effects on the immune system. The synbitoic was composed of two probiotic bacteria (Lactobacillus fermentum ATCC 793 and Bifidobacteria longum ATCC 15707 and a grape -derived prebiotic composed of grape seed polyphenol extract, resveratrol and a concord grape extract. Male mice (C57BL/6) were pretreatment with either nothing (control), BDPP, probiotic or synbiotic and underwent 28 days of chronic unpredicitable stress. After 28 days, animals' behavior reflected an increase in depressive- and anxiety-like behavior, rescued specifically by the synbiotic. This nanostring multiplex analysis reveals both tissue- and treatment-specific effects on immune modulators.
Project description:Micronutrient deficiency (MND i.e., lack of vitamins and minerals) during pregnancy is a major public health concern. Historically, studies have considered micronutrients in isolation; however, MNDs rarely occur alone. Furthermore, the impact of co-occurring MNDs on public health, mainly in shaping mucosal colonization by pathobionts from Enterobacteriaceae family, remain undetermined due to lack of relevant animal models.
Project description:We investigated the effect of pterocarpan-rich extract from soybean leaf on metabolic syndrome and elucidated anti-inflammation mechanism based on RNA-seq transcriptomic profiles in overweight and obese subjects
Project description:The study evaluates the effect of Lactiplantibacillus plantarum IMC 510® supplementation on anthropometric and biochemical parameters, GM composition and gastrointestinal and general symptoms of overweight/obese subjects.
Project description:Gut microbiota has profound effects on obesity and associated metabolic disorders. Targeting and shaping the gut microbiota via dietary intervention using probiotics, prebiotics and synbiotics can be effective in obesity management. Despite the well-known association between gut microbiota and obesity, the microbial alternations by synbiotics intervention, especially at the functional level, are still not characterized. In this study, we investigated the effects of synbiotics on high fat diet (HFD)-induced metabolic disorders, and systematically profiled the microbial profile at both the phylogenetic and functional levels. Synbiotics significantly reversed the HFD-induced change of microbial populations at the levels of richness, taxa and OTUs. Potentially important species Faecalibaculum rodentium and Alistipes putredinis that might mediate the beneficial effects of synbiotics were identified. At the functional level, short chain fatty acid and bile acid profiles revealed that interventions significantly restored cecal levels of acetate, propionate, and butyrate, and synbiotics reduced the elevated total bile acid level. Metaproteomics revealed the effect of synbiotics might be mediated through pathways involved in carbohydrate, amino acid, and energy metabolisms, replication and repair, etc. These results suggested that dietary intervention using our novel synbiotics alleviated HFD-induced weight gain and restored microbial ecosystem homeostasis phylogenetically and functionally.
