In this study, a novel peptide GPPGPA was screened from the collagen hydrolysates of Chinese giant salamander (Andrias davidianus) skin, and its anti-diabetes mechanism predicted by network pharmacology, an inhibitory effect on α-glycosidase protective IR (insulin resistance) oxidative stress IR-HepG2 cells were detected. Through pharmacology screening, found to have good drug-like properties, 103 targets overlap with T2DM targets. These mainly enriched in PI3K-Akt signaling pathway...

A strategy to manipulate the disulfide bond breaking triggered unfolding, and subsequently assembly of human serum albumin (HSA) in a lipophilic drug-dependent manner is present. In this study, hydrophobic region, molecular switch HSA, was regulated form HSA-paclitaxel (HSA-PTX) nanoparticles by facile route. High-resolution transmission electron microscopy fluorescence quenching indicate that HSA coassembled with PTX, which acts as bridge core-shell about 50-240 nm size, PTX might bind...

In this study, we examined the effect of xylooligosaccharide (XOS) supplementation on growth performance, carcass characteristics, and meat quality Hu lambs. total, 60 lambs (two months old weighing 17.32 ± 0.81 kg) were randomly assigned to four treatment groups, each with three replicates five per replicate. The fed basal diets supplemented 0, 1.5, 3, or 4.5 g/kg XOSs in a diet for days, groups designated XOS0%, XOS1.5%, XOS3%, XOS4.5%, respectively. results revealed, compared theXOS0%...

A two-stage simulated gastro-intestinal (GI) digestion model (2 h pepsin treatment and subsequent 2 pancreatin at 37 °C) was used to explore the antioxidant activity of digested products Cyprinus carpio haematopterus scale gelatin with different molecular weights (MW). From gastric phase intestinal phase, hydrolysis degree increased from 2.6 ± 0.4% 16.9 0.7%. The fraction 0–1 kDa (JCP3) exhibited best activities in hydroxyl radical scavenging, reducing power, metal chelating activity. 1–3...

The molecular mechanism of interaction between aloe-emodin (AE) and trypsin was investigated, exhibiting remarkable outcomes. To detect the mechanism, binding AE with examined by a multi-spectroscopy docking method. Results showed that would lead to static quenching their forces were van der Waals hydrogen bonding. results simultaneous three-dimensional fluorescence spectroscopy combination caused changes in microenvironment around fluorophore, which might change spatial structure trypsin....
