Advance care planning in patients undergoing surgery to resect pancreatic adenocarcinoma: Underlying tension between balancing hope and realism.

Background: The timing and the dose of Advanced Care Planning in patients with pancreatic ductal adenocarcinoma undergoing curative-intent resection are generally dictated by the surgeon performing the operation.

Methods: A qualitative investigation using 1:1 interviews with 40 open-ended questions was conducted with a convenience sample of 10 high-volume pancreatic surgeons from across the country. The grounded theory approach was used for data analysis.

Protein-Nucleic Acid Conjugation with Sterol Linkers Using Hedgehog Autoprocessing.

Hedgehog (Hh) precursor proteins contain an autoprocessing domain called HhC whose native function is protein cleavage and C-terminal glycine sterylation. The transformation catalyzed by HhC occurs in from a precursor protein and exhibits wide tolerance toward both sterol and protein substrates. Here, we repurpose HhC as a 1:1 protein-nucleic acid ligase, with the sterol serving as a molecular linker.
