The digestive behavior and antioxidant activity of composites before and after simulating gastrointestinal fluid in vitro were studied as well. At the same time, molecular dynamics simulation techniques were used to reveal the molecular mechanism behind the formation of the composite between the two.

Used extensively in industrial and agricultural sectors, TCBs are prevalent pollutants in various ecosystems, including air, food, surface water, groundwater, sediment, soil, and sewage. This is a concern because of their tendency to accumulate in lipid-containing tissues of animals and humans and potentially serious risks to human health and ecosystems. Information showing the presence of TCBs in food, drinking water, and even human breast milk underscores the need for ongoing assessment of the extent of these contaminants in food to measure the potential exposure to these chemicals.

The purpose of this study was to investigate whether <i>Lithospermum erythrorhizon</i> and <i>Lonicera japonica</i> complex extract (LELJ) has a beneficial effect on dexamethasone (Dexa)-induced muscle atrophy. In Dexa-induced myotube atrophy, treatment with LELJ increased myotube diameter, decreased the expression of muscle atrophy markers, and increased the expression of myosin heavy chain (MHC) isoforms. Supplementation with LELJ improved muscle function and performance in mice with Dexa-induced muscle atrophy as demonstrated by grip strength and running tests. Additionally, it increased skeletal muscle mass, size, and expression of MHC isoforms and protein synthesis-related markers. Furthermore, it reduced the upregulated protein levels of skeletal muscle atrophy markers in Dexa-treated mice. Supplementation with LELJ reversed Dexa-induced translocation of the glucocorticoid receptor and forkhead box O3 from the cytosol to the nucleus in skeletal muscles. LELJ also ameliorated age-related muscle loss by extending lifespan and increasing locomotor capacity in <i>Caenorhabditis elegans</i>. We identified loganin and lithospermic acid as bioactive compounds of LELJ and found that treatment with these agents increased myotube diameter, MHC isoform, and puromycin protein levels, and decreased atrophy markers in Dexa-treated myotubes.

Molecular mechanism studies revealed that the observed decrease in inflammatory factor expression may be attributed to the inhibition of phosphorylated c-Jun N-terminal kinase activity by GLSO. Furthermore, intraperitoneal injection of GLSO in a ligature-induced PD mouse model led to a notable reduction in periodontal inflammation and alveolar bone loss, accompanied by decreased levels of MMP-1 and IL-8. These in vivo results support the potential therapeutic efficacy of GLSO in alleviating PD symptoms. Overall, our study provides novel insights into the beneficial effects of GLSO in PD management.
