The present invention relates to a polysaccharide with cytotoxic activity against human colon, human lung, human melanoma and murine leukaemia tumour cells, as well as antioxidant and healing activity. The invention also relates to a method for producing the polysaccharide, its uses and applications, particularly via drugs for treating cancer and / or antioxidant and healing compositions. The polysaccharide of the present invention can be produced from biomass, particularly from fungi, and preferably from the fungus Bovistella utriformis.

Various embodiments of a gut microbiome modulating composition comprises a blend of a polyphenol and an oligosaccharide. Various embodiments of the polyphenol may comprise at least approximately 5% by weight chlorogenic acid. Various embodiments of the oligosaccharides may be standardized to a degree of polymerization of at least three to reduce digestibility. Administration of an effective amount of the gut microbiome modulating composition to a person or animal may stimulate the growth of at least one of Akkermansia muciniphila, Lactobacillus, and Bifidobacterium bacteria in the colon, which may reduce permeability of the colon, increases short chain fatty acid production in the colon, and / or modulate causes immunomodulation of human colon cells. The gut microbiome modulating composition may provide protective effects against obesity-related chronic diseases.

The present disclosure provides compositions and methods of modulating the response of a subject to an anti-cancer treatment, comprising fecal-derived extracellular vesicles, filtrates or compositions comprising the same, which can be administered with an anti-cancer treatment. The composition disclosed herein can be substantially free of living biological material present in the human colon and biological material less than about 5-10 kDa molecular weight.

The invention belongs to the field of biological medicine, and relates to broad-spectrum antibacterial peptide derived from periplaneta americana and anti-tumor application of the broad-spectrum antibacterial peptide. The PA-1 and the PA-2 are both novel alpha-spiral cationic peptides and show remarkable inhibitory activity on pseudomonas aeruginosa, salmonella typhimurium, staphylococcus aureus, staphylococcus epidermidis and carbapenem-resistant acinetobacter baumannii, and the minimum inhibitory concentration on the carbapenem-resistant acinetobacter baumannii reaches 11 [mu] mol / L. In addition, PA-1 and PA-2 can also obviously inhibit the growth of human colon adenocarcinoma cells SW480, cervical cancer cells Hela and gastric cancer cells HGC-27, and show better anti-tumor potential. And the PA-1 and the PA-2 have good thermal stability, pH stability, salt stability and enzyme stability. The two novel active peptides PA-1 and PA-2 provided by the invention show relatively high medicinal values in the antibacterial and anti-tumor fields, and particularly provide a new choice for clinical treatment of carbapenem-resistant acinetobacter baumannii infection.

The application discloses an anti-digestive polysaccharide-based food colon simulation fermentation and multi-dimensional online analysis system and belongs to the technical field of food. The fermentation simulation of each colon part is completely carried out according to the human digestive fermentation process and physiological environment, and intestinal mucosa globules are added to simulate the human intestinal mucosa environment, so that the degradation process of the anti-digestive polysaccharide-based food by part microorganisms in the human colon under the ex vivo condition is simulated, and the fermentation condition of the anti-digestive polysaccharide-based food after entering the colon can be observed online, which is in line with the real human physiological environment.

The invention discloses application of spermidine and a composition thereof in preparation of medicines for preventing or treating radioactive diseases and related complications thereof. According to the application, firstly, an in-vitro experiment shows that spermidine can be used for remarkably relieving proliferation arrest of radiation-induced human colonic dry organs and inhibiting apoptosis of colonic epithelium organs; furthermore, animal in-vivo experiments show that spermidine can repair radioactive injury, including enteritis, intestinal injury, intestinal fibrosis and the like caused by radiation; the application firstly proposes and proves that spermidine can be used as a radiation protective agent and a safe medicine component for treating radioactive injury, and has a good clinical application prospect and application value.
