Low molecular fucoidan alleviated alcohol-induced liver injury in BALB/c mice by regulating the gut microbiota-bile acid-liver axis.

Fucoidan has attracted significant attention owing to its remarkable bioactivities, but the effect of molecular weight (Mw) on its activities in the context of alcoholic liver diseases (ALD) is poorly understood. In this study, low Mw fucoidan (OSLF) was prepared, and its protective effect against alcohol-induced liver injury was assessed in a mouse model. OSLF increased weight gain and colon length, improved lipid disorders, and reduced oxidative stress in mice exposed to alcohol, alleviating liver injury.

Curcumin-loaded polysaccharide microparticles alleviated DSS-induced ulcerative colitis by improving intestinal microecology and regulating MAPK/NF-κB/Nrf2/NLRP3 pathways.

Curcumin (Cur) exerts many benefits on the host, but its application is limited by its poor bioavailability. In this study, composite polysaccharide microparticles loading Cur (Cur-CPM) was prepared by food-grade materials and gel technology. Its properties were analyzed via the in vitro and in vivo models, and then its benefit on gut health was assessed in DSS-treated mice.

Photocatalytic removal using g-CN quantum dots/BiTiO composites.

In this work, a simple method to load of g-CN quantum dots (CN QDs) onto BiTiO (BTO) microsphere with the amount of CN QDs (3, 7, 10 and 15%). The photocatalyst was used for the treatment of water pollutants under visible-light illumination, which proved that CNBTO composites showed improved photocatalytic activity matched up to pure BTO. Reformation of BTO with CN QDs enhanced the light assimilation capacity, and promoted the isolation of photo-induced electron-hole pairs.
