    Abstract

    Lactobacillus salivarius Promotion of Intestinal Stem Cell Activity in Hens is Associated with Succinate-Induced Mitochondrial Energy Metabolism

    The preliminary screening of active ingredient of predominant Lactobacilli was performed by component feeding trial. The active ingredient was administered to intestinal stem cells in vivo and in vitro to confirm its direct regulation and explored the underlying mechanism.

    Abstract

    Self-Assembled Micelle Derived from Pterostilbene Ameliorate Acute Inflammatory Bowel Disease

    The anti-oxidant effects and anti-inflammatory effects of PEGylated pterostilbene micelles (PTENPs) were determined under in vitro and in vivo conditions. It was found that compared with free PTE, PTENPs could effectively ameliorate acute IBD with low toxicity.
