MORPHOLOGY, TAXONOMY AND DISTRIBUTION OF THE CRETACEOUS CORAL GENUS PREVERASTRAEA (LATE BARREMIAN-CENOMANIAN; SCLERACTINIA)

The Cretaceous coral genus Preverastraea is being revised, mainly on the basis of sample material.This cerioid, occasionally astreoid or phaceloid, genus is characterised by round or polygonal calices, compact septa in here a regular hexameral symmetry and lonsdaleoid septa.The wall is of the same structure as the septa.The genera Bogdanovicoenia,

Rebalancing of mitochondrial homeostasis through an NAD+-SIRT1 pathway preserves intestinal barrier function in severe malnutritionResearch in context

Summary: Background: The intestine of children with severe malnutrition (SM) shows structural and functional changes that are linked to increased infection and mortality.SM dysregulates the tryptophan-kynurenine pathway, which may impact processes such as SIRT1- and mTORC1-mediated autophagy and mitochondrial homeostasis.Using a mouse and organoid
