Exercise training is critical for the early prevention and treatment of obesity and diabetes ***,the mechanism with gut microbiota and fecal metabolites underlying the effects of voluntary wheel running on high-fat diet induced abnormal glucose metabolism has not been fully elaborated.C57BL/6 male mice were randomly assigned to 4 groups according to diets(fed with normal chow diet or high-fat diet)and running paradigm(housed in static cage or with voluntary running wheel).An integrative 16S rDNA sequencing and metabolites profiling was synchronously performed to characterize the effects of voluntary wheel running on gut microbiota and *** showed that voluntary wheel running prevented the detrimental effects of high-fat feeding on glucose metabolism 16S rDNA sequencing showed remarkable changes in Rikenella and Marvinbryantia *** profiling indicated multiple altered metabolites,which were enriched in secondary bile acid biosynthesis *** conclusion,our study indicated that voluntary wheel running significantly improved glucose metabolism and counteracted the deleterious effects of high-fat feeding on body weight and glucose *** further found that voluntary wheel running could integratively program gut microbiota composition and fecal metabolites changes,and may regulate muricholic acid metabolism and secondary bile acid biosynthesis in high-fat fed mice.

Background Cadmium(Cd) pollution in agricultural soils has become a priority environmental concern globally. A reasonable application of passivators is critical to address the problem. In this study, we examined the remediation effects of rice husk biochar(r BC) and sepiolite(Sep) as single and combined(r BC + Sep) treatments on Cd pollution in a weakly alkaline soil using three maize cultivars(Liyu 16, Zhengdan 958, and Sanbei 218) as test crops. We also explained the mechanisms involved in the remediation *** The pseudo-second-order kinetic equation and Langmuir model could well describe the adsorption process of r BC + Sep for Cd2+. Compared with the control treatment(CK), soil available Cd concentration decreased by 29.51–36.34% under r BC + Sep treatment(p 0.05).Conclusions The application of 0.2% r BC + 0.5% Sep composite passivation material to weakly alkaline Cd-contaminated soil can effectively reduce the Cd concentration of soil and maize.
