Collagen peptides can promote wound healing and are closely related to microbiome colonization. We investigated the relationship among collagen peptides, healing, microflora colonization by administering murine model with Salmo salar skin (Ss-SCPs) Tilapia nilotica (Tn-SCPs). analyzed vascular endothelial growth factor (VEGF), fibroblast factors (β-FGF), pattern recognition receptor (NOD2), antimicrobial (β-defence14, BD14), proinflammatory (TNF-α, IL-6, IL-8) anti-inflammatory (IL-10)...

Abstract Background Skin tissue is vital in protecting the body from injuries and bacterial infections. Wound infection caused by colonization one of main factors hindering wound healing. a large number bacteria can cause to enter continuous stage inflammation, which delays Hydrogel dressing composed natural synthetic polymers, absorb fluid, improve local microenvironment wound, promote However, preparation process hydrogel, complex poor biological efficacy limit application hydrogel...

The objective of this study was to determine the effects myofibrillar protein (MP) characteristics from tilapia, hairtails, and squid on gel properties, microstructure, emulsification stability surimi gels with increasing concentrations fish oil (FO). surface hydrophobicity (38 μg) MP significantly lower than that tilapia hairtail (P < 0.05), its content (21 g/100 g) were higher those 0.05). Combined firmer structure in microstructure more intuitively indicated FO occupied void spaces...

Areca nut (Areca catechu L.) seeds are rich in polyphenols, while few studies focused on it. This study was designed to obtain the maximum extraction yield of areca seed polyphenol (ACP). An ultrasonic-assisted method optimized by response surface methodology (RSM) established extract ACP. Under optimal conditions (ultrasonic power 87 W, ethanol concentration 65%, temperature 62℃, and time 153 min), actual ACP 139.62 mg/g. Then we investigated effects proliferation, differentiation...

Tilapia produces a large number of by-products during processing, which contain potentially flavorful peptides. The application PyRx software enabled batch molecular docking andscreening 16 potential salty peptides from 189 identified in the enzymaticdigestion tilapia by-products. According to sensory analysis, all werepredominantly with threshold 0.256 - 0.379 mmol/L some sournessand astringency, among HLDDALR had highest intensity, followedby VIEPLDIGDDKVR, FPGIPDHL, and DFKSPDDPSRH. I...

To mitigate the potential environmental risks caused by nitrogen compounds from industrial wastewater, residual ammonia after conventional wastewater treatment should be further eliminated. In this work, an electrochemical oxidation process for converting to in actual dyeing was investigated. The effects of main operating parameters, including initial pH value, applied current density, NaCl concentration, and flow, were investigated on removal products distribution. Experimental results...

Polyphenol can improve osteoporosis and is closely associated with gut microbiota, while the mechanism relationship among polyphenol, osteoporosis, microbiota colonization remain unclear. Here, an rat model established by ovariectomy was employed to investigate improving of arecanut (Areca catechu L.) seed polyphenol (ACP) on regulating microbiota. We analyzed bone microstructure, Paneth cells, microbial protein (lysozyme (LYZ)), proinflammatory cytokines, macrophage infiltration levels,...

Osteoporosis is a global health problem, and it of great significance to replace the drugs with natural functional factors. In this study, we investigated antiosteoporotic activity lipids prepared from Tilapia nilotica fish head (THLs) in ovariectomized osteoporosis rats. THLs are composed neutral (NL, 77.84%), phospholipids (PL, 11.86%), glycolipids (GL, 6.47%). There were apparent differences fatty acid composition disparate components, PL contains most abundant Ω-3 polyunsaturated acids....

Currently, the effect of heat treatment on complex coacervation behavior whey isolate protein (WPI) with gum arabic (GA) is undiscussed. In this work, WPI or without and GA in different environments was investigated. The results showed that coacervates were formed at a mass ratio 2:1 pH 3.5, which confirmed by fluorescence spectroscopy results. Heat increased surface charge WPI, reduced saturated adsorption concentration GA, enhanced sensitivity reaction to salt ions. Fourier infrared...

The effect of coconut exocarp flavonoids (CF) combined with cold plasma (CP) treatment on oyster preservation during refrigerated storage was investigated. It observed without suffered the most serious microbial spoilage and chemical changes storage. CP significantly inhibited bacteria, inactivated endogenous lipid hydrolases LOX activities (P < 0.05). Simultaneously, it caused undesirable polyunsaturated fatty acid (PUFA) oxidation glycerophospholipid species depletion, while extended...

In this study, a total of 24 male Sprague Dawley rats were randomly divided into 3 group (Collagen peptide Salmon salar skin group, Ss-SCP; Collagen Tilapia nilotica Tn-SCP and Model control MC) to investigate the impact high-collagen diet on gut microbiota host health. After 16 days intervention, body weights Ss-SCP intervention groups significantly increased liver index was also remarkably higher than that MC group. The acetic acid propionic levels in feces both valerate level lower With...
