Unlabelled: polysaccharides (FVP) exhibit many biological activities, but the effects on gut microflora and metabolism were still unclear. Here, we explored the composition of FVP, their influence on human gut microflora composition and metabolites. FVP were used to vitro fermentation through human fecal inoculums. In addition, 16S rRNA sequencing were used to assess the effects of FVP on the gut microbiota. The metabolic profiles were investigated using untargeted metabolomics approaches in the LC-MS platform. The results showed that FVP was mainly consisted of glucose, mannose, xylose, fucose and galactose. FVP is shown to increase the relative abundances of , as well as and remarkably decrease the numbers of genera coupled with . The differential metabolites were identified and mainly involved the metabolism of glycerophospholipid, linoleic acid and synthesis of unsaturated fatty acids. FVP may exhibit biological activity function by regulating gut microflora composition and metabolites.

Microbiome and radiotherapy represent bidirectionally interacting entities. The human microbiome has emerged as a pivotal modulator of the efficacy and toxicity of radiotherapy; however, a reciprocal effect of radiotherapy on microbiome composition alterations has also been observed. This review explores the relationship between the microbiome and extracranial solid tumors, particularly focusing on the bidirectional impact of radiotherapy on organ-specific microbiome.

The human bowel is exposed to numerous biotic and abiotic external noxious agents. Accordingly, the digestive tract is frequently involved in malfunctions within the organism. Together with the commensal intestinal flora, it regulates the immunological balance between inflammatory defense processes and immune tolerance.

Owing to the high prevalence of gastrointestinal dysfunction in patients, the gut-brain axis is considered to play a vital role in neurodevelopment diseases. Recent pieces of evidence have pointed to the usage of antibiotics at an early developmental stage to be a causative factor in autism due to its ability to induce critical changes in the gut microbiota. The purpose of the study is to determine the neuroprotective effect of capric acid (CA) on autism in antibiotic-induced gut dysbiosis in rodents.

Objective: To characterize early physiologic stresses imposed by surgery by applying metabolomic analyses to deeply phenotype pre- and postoperative plasma and urine of patients undergoing elective surgical procedures.
Background: Patients experience perioperative stress through depletion of metabolic fuels. Bowel stasis or injury might allow more microbiome-derived uremic toxins to enter the blood, while the liver and kidney are simultaneously clearing analgesic and anesthetic drugs.

Background: Gut microbiota plays an important role in multiple human physiological processes and an imbalance in it, including the species, abundance, and metabolites can lead to diseases. These enteric microorganisms modulate immune homeostasis by presenting a myriad of antigenic determinants and microbial metabolites. Medicinal and food homologous (MFH) plants, edible herbal materials for both medicine and food, are important parts of Traditional Chinese Medicine (TCM).
