Youngest known case of a pancreatic perivascular epithelioid cell tumor

open access: yesJPGN Reports, EarlyView.
Abstract Perivascular epithelioid cell tumors (PEComas) are a rare type of mesenchymal tumor that can arise in any part of the body. As of 2024, 37 cases of pancreatic PEComas had been reported in the literature with patients ranging in age from 17 to 74 years old.

A Method of Locating the Abutment Screw Access Channel with Cone-Beam Computed Tomography and a 3D-Printed Drilling Guide [PDF]

open access: yes, 2018
In managing loose abutment screws, locating precisely the position of the screw access channel is difficult. This technique describes the use of cone-beam computed tomography (CBCT) and surgical guide planning software to locate the screw access channel ...

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...
