The “Panghkawkwo graptolite bed” (Llandovery, Silurian), Myanmar and the location of the Sibumasu (or Sibuma) Terrane in the Silurian [PDF]
, 2017 The “Panghkawkwo graptolite bed” is shown to comprise several graptolitic horizons extending through the Aeronian (middle Llandovery) and into the lower Telychian (upper Llandovery). Graptolite assemblages are diverse indicating an outer shelf (or deeper)

<i>Clostridium difficile</i> and gut health: Bacteria, the gut microbiome, and diet. [PDF]
IMetaOmicsThis review explores the mechanisms underlying Clostridium difficile infection (CDI), focusing on the pathogen's life cycle and its pathogenicity within the host. It further explores the interactions between the gut microbiome, gut metabolites, and CDI. Additionally, the review highlights dietary modulation as a promising strategy to restore gut health,
