Article Abstract
The influence of hydrogen peroxide (HO) on the ROS metabolism and its relationship to pulp breakdown of fresh longan cv. Fuyan during storage was evaluated. Contrasted to control fruit, HO-treated samples manifested a higher index of pulp breakdown, an enhanced rate of O generation, and an increased amount of MDA, but lower APX, CAT and SOD activities, reduced expressions of and , and lower concentrations of total phenolics, flavonoid, AsA, and GSH as well as lower levels of free radicals scavenging capacity. These data revealed that HO-induced pulp breakdown of longan was because HO reduced ability of removing ROS but increased ROS generation and accumulation, which promoted peroxidation of cell membrane lipid, and subsequently led to damaging cell membrane structure and breakdown occurrence in pulp of postharvest fresh longan.

Human Dental Pulp Stem Cells (hDPSCs) represent a remarkable cell source for tissue engineering and regenerative medicine, offering significant potential for use in personalized medicine and autologous therapies. Decellularized extracellular matrix (ECM)-derived biological scaffolds show excellent properties for supporting cell delivery and growth in both in vitro and in vivo applications. These scaffolds provide essential biochemical cues that regulate cellular functions and offer a more accurate representation of the in vivo environment.

Consumption of mango has been associated with a number of beneficial effects on health which have been attributed to phenolic catabolites originating from (poly)phenols following ingestion. To investigate the origins of potentially bioactive phenolic catabolites, ileostomists and subjects with a full gastrointestinal tract on a low(poly)phenol diet ingested a mango pulp purée containing 426 μmol of (poly)phenols consisting mainly of gallotannins and cinnamic acids, along with 231 μmol of the aromatic amino acids phenylalanine and tyrosine. Over a 24 h period post-mango intake plasma and urine were collected and analysed by UHPLC-HRMS.

In this study, the intrinsic properties of jujube were modified through co-fermentation with three non-Saccharomyces yeasts and Lactiplantibacillus plantarum to solve the stickiness and caking problems of jujube powder. Results showed that sugar content in jujube pulp was significantly reduced through microbial metabolism. Notably, sucrose, the major contributor to stickiness, was reduced from over 15.
