Disclosed is a pharmaceutical composition or food composition for the treatment or prevention of hypertension, containing a peptide isolated from a fraction of a flounder surimi hydrolysate as an active ingredient and is based on the finding that the flounder surimi has an effect of reducing blood pressure, and the hydrolysate of the flounder surimi, the fraction of the hydrolysate of the flounder surimi and peptides isolated from the fraction of the hydrolysate of the flounder surimi have an inhibition activity against an angiotensin I converting enzyme (ACE). Thus, peptides isolated from the fraction of the hydrolysate of the flounder surimi can be used for pharmaceutical compositions or food compositions for treating or preventing hypertension. Also, the present invention is based on the finding that the hydrolysate of the flounder surimi and peptides isolated therefrom have radical scavenging effect and a protective effect against oxidative stress and are thus capable of inhibiting ROS production, lipid peroxidation and apoptosis. Accordingly, peptides isolated from fractions of the hydrolysate of the flounder surimi can be used for food compositions for antioxidation.

The present invention relates to an antibacterial peptide derived from Erythroculter ilishaeformis and use thereof. The amino acid sequence of the antibacterial peptide of the present invention includes an amino acid sequence as shown in SEQ ID NO: 1. The present invention further discloses use of the antibacterial peptide in the preparation of an anti-aquatic-bacterium drug for aquaculture animals. The present invention provides a novel antibacterial peptide, discloses a function of the novel antibacterial peptide for resisting aquatic bacteria, and provides candidate molecules for preventing and treating bacterial diseases in the culture process of Erythroculter ilishaeformis.

Provided are dietary supplement composition comprising one or both of L-theanine and a trace mineral complex, optionally in combination with bioactive peptides, in an amount or amounts individually or in combination effective to promote gut health. Further optional components include a fiber oligosaccharide prebiotic, a polyphenol prebiotic, and a polynucleotide or blend. Examples of benefits include one or more of: —an increase in the amount of total short-chain fatty acid production or of at least one of propionate, acetate and butyrate; —an increase the expression or level of at least one tight junction protein (for example, claudin-1, claudin-3, claudin-4, occludin, or a zona occludens protein) or mucin-3 or decrease the expression or level of claudin-2; —an increase in transepithelial electrical resistance; —an increase in the abundance or diversity of a member or phylum of the intestinal bacterial community of the Intestinal lumen or mucus area (for example, Firmicutes, Bacteroidetes, Lactobacilli, Bifidobacteria, F. prausnitzii, or A. muciniphila); —an increase in the expression or level of at least one intestinal surface area marker protein (for example, villin, myosin, cadherin or sucrase-isomaltase). Methods for using such supplements are also disclosed.

The present document describes uses and methods of using a gem-difluorinated C-glycopeptide compound of general formula I, or a pharmaceutically acceptable base, addition salt with an acid, hydrate or solvate of the compound of general formula I for inhibition or prevention of immune rejection of an isolated graft contacted with said compound, prior to transplantation in a subject in need thereof.
