Intraductal papillary mucinous neoplasms (IPMNs) are a prevalent subtype of pancreatic cystic lesions, especially among individuals with liver cirrhosis. Intraductal papillary neoplasms of the bile duct (IPNBs) differ in histopathology based on the location and cellular variability in each location. Intrahepatic IPNBs are less aggressive than the extrahepatic variant, highlighting its heterogeneity and complexity.

Methods: Nineteen semi-structured one-to-one telephone or online video interviews were conducted with dentists involved in SCRiPT, using an interview guide informed by the Theoretical Domains Framework (TDF). Data were initially analysed deductively using a framework informed by the TDF, and subsequently using reflexive thematic analysis.
Nanoparticles are widely studied for delivering treatments to target tissues, but few have reached clinical use. Most nanoparticles encounter blood vessels on their way to target tissues. The inner surface of these vessels is lined with endothelial cells covered by a glycocalyx, an extracellular matrix rich in anionic glycans.

However, there are remaining technical and clinical questions, including questions on reference region selection and on how specific phenotypic presentations and symptoms of Alzheimer disease (AD) are reflected in alterations in synaptic density. Using a synaptic vesicle glycoprotein 2A (SV2A) PET ligand radiolabeled with the F isotope ([F]SynVesT-1), we performed sensitivity analyses to determine the optimal reference tissue modeling approach to derive whole-brain ratio images.
