Constipation, a common gastrointestinal dysfunction, damages patients' life quality and predisposes them to other serious diseases. Current strategies against constipation often cause drug dependency side effects. Here, we demonstrated that broccoli-derived exosome-like nanoparticles (BENs), natural product with high stability, ameliorated LOP-induced in mice. Specifically, orally administered BENs (17.5 mg/kg/d) effectively shortened defecation time, sped up intestinal propulsion rate, increased feces amount constipated also raised excitatory neurotransmitters SP MTL reduced inhibitory VIP ET-1. Mechanistically, were taken by gut microbes, restored LOP-disordered microbiota, altered microbial metabolism of SCFAs tryptophan, as evidenced the results fluorescence microscopy, 16S rRNA gene sequencing, nontargeted metabolomics. Thereinto, BEN-enriched SCFA-producing microorganisms are closely associated levels BEN-elevated indole-3-pyruvic acid 3-indoleacetic highly linked ET-1, SP, levels. Conclusively, BENs, mitigating regulating microbiota tryptophan metabolism, showed potential be developed alternative regimens for constipation.

Disruptions in the gut microbiota can impede gene expression and metabolic enzyme activity, thereby precipitating onset of diverse ailments. Spirulina polysaccharides, which are characterized by their high molecular weight composed multiple monosaccharides connected glycosidic bonds, demonstrate notable biological activity. Gut possesses ability to break down polysaccharides into butyrate, short-chain fatty acids, other metabolites that be readily absorbed utilized human body. Furthermore, have capacity modulate composition products microbiota, thus fostering general well-being averting diseases. This study reviews summarizes critically examines consolidates significant regulatory impacts on elucidating structural attributes potential mechanisms operation. These findings offer a valuable point reference for subsequent advancement prebiotic foods preparations based polysaccharides.

Background The relationship between dysbiosis of the gastrointestinal microbiota and gastric cancer (GC) has been extensively studied. However, alterations in GC patients vary widely across studies, reproducible diagnostic biomarkers for early are still lacking multiple populations. Thus, this study aimed to characterize microbial communities involved carcinogenesis through a meta-analysis published open datasets. Methods We analyzed 16S rRNA sequencing data from 1,642 biopsy samples 394 stool 11 independent studies. VSEARCH, QIIME R packages such as vegan, phyloseq, cooccur, random forest were used processing analysis. PICRUSt software was employed predict functions. Results α-diversity results indicated significant differences intratumoral compared non-cancer patients, while no observed fecal microbiota. Network analysis showed that positive correlation with GC-enriched bacteria increased, GC-depleted decreased healthy individuals. Functional analyses pathways related carbohydrate metabolism significantly enriched GC, biosynthesis unsaturated fatty acids diminished. Additionally, we investigated non- Helicobacter pylori (HP) commensals, which crucial both HP -negative -positive GC. Random models, constructed using specific taxa associated identified LEfSe analysis, revealed combination Lactobacillus Streptococcus included alone could effectively discriminate individuals (area under curve (AUC) = 0.7949). This finding also validated an cohort (AUC 0.7712).

Abstract Chronic constipation is a prevalent clinical condition. Its etiology and pathogenesis have not yet been fully understood. In recent years, mounting evidence suggests close association between chronic intestinal dysbiosis, including alterations in the colony structure metabolites, as well modulation of bowel movements via brain–gut–microbiota axis. With deepening related research, probiotic-related therapies are expected to become potential first-line treatment for future. this review, we summarize current research insights into intricate relationships gut microbiota briefly discuss several different approaches treating constipation. The findings from review may advance our understanding pathological mechanisms underlying and, ultimately, translate them improvements patient care.

Its etiology influenced both genetic environmental factors, with no definitive cause identified specific pharmacological treatments available, posing significant burden on patients’ families society. In recent years, research has discovered that gut microbiota dysbiosis plays crucial role the pathogenesis of ASD. The can influence brain function behavior through gut-brain axis via nervous system, immune metabolic pathways. On one hand, microbes such as Clostridium Prevotella species are found to be abnormal ASD patients, their products, like short-chain fatty acids, serotonin, GABA, also involved pathological process other patients exhibit system dysfunction, cells related cytokines affecting neural activities brain. Currently, intervention methods targeting microbiota, probiotics, prebiotics, fecal transplantation, have shown some potential improving symptoms.
