Postoperative pancreatic fistula after pancreaticoduodenectomy: if you lack knowledge of what to search for, you will be unable to locate what you desire.

Objective: Postoperative pancreatic fistula (POPF) is the most common and critical complication of pancreatoduodenectomy (PD). In this study, we aimed to define preoperative, perioperative, and postoperative conditions that may cause POPF and examine the predictive value of drain fluid amylase (DFA) values in showing the clinical severity of POPF.

Patients And Methods: Between December 2018 and December 2019, 49 patients who underwent PD for malignant reasons by a single team were retrospectively analyzed.

RGDS-functionalized polyethylene glycol hydrogel-coated magnetic iron oxide nanoparticles enhance specific intracellular uptake by HeLa cells.

The objective of this study was to develop thin, biocompatible, and biofunctional hydrogel-coated small-sized nanoparticles that exhibit favorable stability, viability, and specific cellular uptake. This article reports the coating of magnetic iron oxide nanoparticles (MIONPs) with covalently cross-linked biofunctional polyethylene glycol (PEG) hydrogel. Silanized MIONPs were derivatized with eosin Y, and the covalently cross-linked biofunctional PEG hydrogel coating was achieved via surface-initiated photopolymerization of PEG diacrylate in aqueous solution.
