Diterpenoid Diversity across Land Plants
Helvetica Chimica Acta, EarlyView.Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

iMetaOmics, EarlyView.Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.

Laparoscopic Resection of Caudate Lobe Liver Tumors in Clinical Practice
iNew Medicine, EarlyView.ABSTRACT The caudate lobe (Couinaud segment I), owing to its deep location in the posterosuperior liver, intimate encirclement by the inferior vena cava (IVC), and close adjacency to the hepatic hilum and major hepatic veins, presents a formidable anatomical challenge for resection.
