The nine significantly positive compounds were heptanal, nonanal, octanal, (E)-2-hexenal, (E,E)-2,4-decadienal, 2-pentylfuran, 4-methyl-5-thiazoleethanol, 2-furfurylthiol, and (E)-2-decenal. The contributions of nine key aroma compounds were further analyzed by the preference test. (E)-2-decenal, 2-furfurylthiol, and 4-methyl-5-thiazoleethanol showed higher first choice, consumption ratio, and unit contribution rate and were vital to the overall preferred aroma of DFs.Agricultural production-caused water contamination has become an urgent environmental issue that has drawn much attention in recent years. One such contamination case is the environmental disposal of colored effluents from the food processing industry (i.e., food dyes). Effective methods for removing dye contaminants from water have been increasingly sought, and different adsorbents have been developed for this purpose. Here, polysaccharide-based hydrogels derived from cellulose were constructed and used in the removal of methylene blue (MB) (as the representative dye) from an aqueous medium (as simulated dye liquor wastewater). To improve the purification efficiency, TiO2 nanoparticles were encapsulated into cellulose nanofibers, which were consequently changed to hydrogels with respective advantages. The morphology, chemical composition, and structure of the as-prepared polysaccharide-based hydrogels and the transformation process from nanofibers to hydrogels were revealed by scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction, and the presence of a gel network structure and TiO2 nanoparticles was confirmed. As expected, the polysaccharide-based hydrogels exhibited good MB removal performance because of their synergistic effects of absorption and photocatalytic degradation. selleck kinase inhibitor Furthermore, the cell cytotoxicity test showed that the polysaccharide-based hydrogels possessed good biocompatibility. The facile, noncytotoxic, and general strategy presented here could be extended to the preparation of other polysaccharide-based hydrogel materials and has good prospects for application in wastewater treatment.A dodecapeptide with the amino acid sequence of IEELEEELEAER (PIE), identified from Mytilus edulis proteolysis hydrolysates, has shown good bone-forming activity in previous studies. The pharmacokinetics and transport of the PIE peptide in vivo or in vitro were investigated in this study. The results showed that the PIE peptide can be transported into monolayer Caco-2 cells, and the PIE peptide was identified in the serum after the mice reached the highest value of 173.60 ± 60.30 ng/mL, in which it was quantified by an optimized mass spectrometry method. In addition, the PIE peptide has a promoting effect on the bone morphogenetic protein pathway at the gene and protein levels. According to the distribution of PIE-FITC in ovariectomized mice after orally administrated PIE-FITC, it was confirmed that it can enter the gastrointestinal tract and serum, and reach the bones. Taken together, the PIE peptide can be absorbed well both in vitro and in vivo, and it could promote pre-osteoblast differentiation factors.The necrotrophic fungus Botrytis cinerea releases extracellular enzymes that facilitate its penetration into a host. This study functionally characterized the gene pdeR of B. cinerea, which is predicted to encode a Zn(II)2Cys6 zinc finger transcription factor. To investigate the role of pdeR, deleted and complemented strains of pdeR in B. cinerea were generated, which were designated as ΔpdeR and PdeRc, respectively. The ΔpdeR strain exhibited impaired germination and growth compared to the wild-type and PdeRc strains, particularly when provided with maltose as the sole carbon source. When all of the strains were grown on a minimal medium containing polysaccharide as the sole carbon source, the ΔpdeR exclusively showed defects in polysaccharide hydrolysis with reduced gene expression encoding for amylase and cellulase. As far as the involvement of pdeR in carbon metabolism is concerned, metabolic changes were investigated in the ΔpdeR mutant. Comparisons of relative, normalized concentrations of each metabolite showed that the amounts of six metabolites including glucose and trehalose were significantly changed in the ΔpdeR strain. Based on pleiotropic changes derived from the deletion of pdeR, we hypothesized that pdeR has an important role in pathogenesis. When the ΔpdeR strain was inoculated onto pepper plant, the ΔpdeR strain did not cause expansion of the disease lesions from the infection sites, which grew on the surface without any penetration. Taken together, these results show that the deletion of pdeR affected the extracellular enzymatic activity, leading to changes in fungal development, metabolism, and virulence.Early postmortem changes in the whole muscle proteome from normal broiler (NB) and woody broiler (WB) breasts at 0 min, 15 min, 4 h, and 24 h after slaughter were analyzed using two-dimensional gel electrophoresis (2DE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Elongation factor 2, EH domain-containing protein 2, phosphoglycerate mutase 1 (PGAM1), and T-complex protein 1 subunit gamma were differentially abundant in both NB and WB muscles during the early postmortem storage. Twenty additional proteins were differentially abundant among four postmortem time points in either NB or WB muscles. In the postmortem WB, changes in protein degradation were observed, including the degradation of desmin fragments, ovotransferrin chain A, and troponin I chain I. Additionally, a few glycolytic proteins in the WB might have undergone post-translational modification, including enolase, phosphoglucomutase-1, PGAM1, and pyruvate kinase. These changes in protein biomarkers highlight the impact of WB myopathy on postmortem proteome changes and increase our understanding of the relationship between WB conditions, postmortem biochemistry, and meat quality.As a polyphenol, ellagic acid (EA) has shown potential antidepressant activity. In this study, the effects and serum metabolomic analysis of EA against depression were investigated using a chronic unpredictable mild stress-induced (CUMS) model. EA (20 or 100 mg/kg body weight) significantly ameliorated the CUMS-induced depression-like behaviors, including reduced body weight, decreased sucrose preference, and increased immobility time in both the tail suspension test and the forced swimming test. Furthermore, EA attenuated the CUMS-induced hippocampal damage and significantly increased the brain-derived neurotrophic factor (BDNF) and the serotonin (5-HT) levels as well as suppressed the inflammatory response. The metabolomics analysis showed that the disturbance of glycerophospholipid (phosphatidylethanolamine and phosphatidylinositol), amino acid (l-arginine and N-stearoyl serine), and purine (uric acid) metabolism induced by CUMS was attenuated by the EA treatment. Furthermore, the correlation analysis indicated that the metabolite changes were strongly correlated with behavioral disorders, BDNF, 5-HT, and inflammatory cytokines levels.
