    Our previous work revealed the microbiota-dependent beneficial effects of inulin in obese male mice, but the effects in obese female mice were not determined. High-fat diet (HFD)-induced obese female mice were switched to normal diets and gavaged with normal saline or inulin for 10 weeks. Inulin supplementation significantly accelerated weight loss and reversed HFD-induced gut microbiota dysbiosis in obese female mice, and also reduced the ratio of Firmicutes/Bacteroidetes and enriched the abundance of norank_f_Muribaculaceae and Alistipes. In addition, 52 key serum metabolites were distinctly altered after inulin supplementation. Among them, andrographolide and monoacylglycerols (18:4) increased more than 9-fold and 14-fold, respectively, while phosphatidylcholine (PC) (18:1e/2:0), PC (20:1/20:2) and PC (19:1/19:1) decreased. In conclusion, gut microbiota and metabolites were closely associated with the beneficial effects of inulin in accelerating weight loss in obese female mice.</p

    Biobased Inverse Vulcanized Polymer from Magnolol as a Multifunctional Ingredient for Carbon-Black-Reinforced Rubber Composites

    Inverse vulcanization provides a facile route to transform industrial byproduct sulfur into attractive polymeric materials with a variety of applications. Herein, an inverse vulcanized copolymer (PSM) was synthesized by copolymerization of biomass magnolol and sulfur. PSM presents outstanding intrinsic flame retardancy by the formation of a highly pyrolysis-resistant carbonaceous material during combustion. Especially, it can serve as a multifunctional ingredient when utilized in rubber composites. The presence of polysulfide segments and biphenol moieties enables PSM to cross-link rubber effectively and react with the oxygenic groups on the surface of carbon black (CB), thus resulting in the improvement of CB dispersion and stronger interfacial interaction between a rubber matrix and nanofillers than the conventional sulfur-cross-linked rubber composite. Incorporation of PSM also significantly retards the thermo-oxidation aging of the composites due to its radical scavenging capability. Moreover, the dynamic covalent polysulfide segments in the system confer the PSM-cross-linked rubber material reprocessability and recyclability

    <p>Mice were sacrificed on 3, 5, 7 dpi, and the brains, skeletal muscle and lungs of mice were removed. Then the tissue was weighted and lysated by cold PBS, followed by centrifugation at 3,000×g for 10 min at 4°C. The concentrations of Ang II and NA were determined using ELISA kits. Data are expressed as mean ± SEM. *<i>P</i><0.05.</p

    <p>Mice were sacrificed on 3, 5, 7 dpi. The removed organ or tissue were sliced and stained with H&E. Brain from EV71-infected mice exhibited perivascular cuffing (indicated by red solid arrows). Skeletal muscle from EV71-infected mice appeared necrotizing myositis with muscle fibers rupture (indicated by orange solid arrows) at 5 dpi and 7 dpi. Erythrocyte-filled fluid in the alveolar spaces was found in lungs (indicated by black solid arrows) from EV71-infected mice at 7 dpi. Bar = 100μm.</p
