Joint technique "parallel peptide synthesis & de novo sequencing" development for the structure verification and high-throughput activity screening of biological peptides from sea cucumber (Stichopus japonicus) intestinal hydrolysate.

This study introduces a novel joint technique combining "parallel peptide synthesis" and "de novo sequencing", which facilitates the high-throughput screening and structure validation of biological peptides derived from food and traditional Chinese medicine (TCM). Sea cucumber (Stichopus japonicus) was used as a model organism, undergoing simulated gastrointestinal digestion followed by de novo sequencing to predict potential peptides. Subsequently, cost-effective filter pipette tips were innovatively employed as parallel reaction vessels, enabling efficient peptide synthesis through the microfluidic flow of amino acid solutions over the loaded resin.

Bromide as Noninnocent Ligand to Iron Tames Fenton Chemistry for Chemoselective Nondegrading Oxidation.

It has long been the chemistry dogma that the nitrogen-based ligand of iron complexes determines the redox reactivity; tetra- and/or pentadentate nitrogen-based ligand (N-ligand: PDP, porphyrin, N4Py) enables chemo-selective oxidation through high-valent iron species (Fe═O), while bi- and/or tridentate N-ligand leads to the generation of highly reactive oxygen species (ROS) (i.e., hydroxyl radical) via a Fenton chemistry pathway.

A study on the tourism efficiency of tourism destination based on DEA model: A case of ten cities in Shaanxi province.

Exploring the of regional tourism efficiency is of great significance in promoting high-quality development of regional tourism. However, there are not many studies that measure the quality development of tourism destinations from the perspective of inputs and output.

Curcumin protects against bisphenol A-induced hepatic steatosis by inhibiting cholesterol absorption and synthesis in CD-1 mice.

Curcumin is a polyphenol extracted from the rhizome of turmeric, and our previous research showed that curcumin inhibited cholesterol absorption and had cholesterol-lowering effect. Bisphenol A (BPA), a common plasticizer, is widely used in the manufacture of food packaging and is associated with non-alcoholic fatty liver disease (NAFLD). We hypothesized that curcumin could protect against BPA-induced hepatic steatosis by inhibiting cholesterol absorption and synthesis.

Bisphenol A induced hepatic steatosis by disturbing bile acid metabolism and FXR/TGR5 signaling pathways via remodeling the gut microbiota in CD-1 mice.

Our previous studies found that bisphenol A (BPA) exposure induced hepatic steatosis and gut microbiota dysbiosis. However, whether the gut microbiota-dependent BA metabolism alterations were involved in BPA-induced hepatic steatosis remains unclear.
