Abstract
Background Conscious sedation is not routinely administered for therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in many countries. The aim of our retrospective study was to compare the safety and rate of success and complications during common bile duct (CBD) stone extraction using ERCPs performed with no-sedation (NS) or under general endotracheal anesthesia (GET). Methods The medical records of all patients who underwent ERCP for biliary stone extraction between January 2010 and September 2013 were reviewed, and patients classified to the NS and GET groups. The primary outcomes were the rate of success of complete stone removal and rate of complications, including post-ERCP pancreatitis (PEP), perforation, bleeding, pneumonia, and mortality within 30 days post-ERCP. Operative time was recorded for analysis. Results During the study period, 630 patients underwent ERCP, 402 with NS and 105 with GET. Among the 402 patients in the NS group, 37 (9.2%) could not complete the procedure due to an inability to tolerate the procedure. The success rate of complete stone extraction was higher among patients in the GET group than the NS group (94.3% versus 75.6%, respectively; p < 0.001). The rate of contrast injection into the pancreatic duct was higher for the NS than GET group (24.9% versus 15.2%, respectively; p = 0.008). Although non-significant, there was a higher incidence of post-ERCP pancreatitis (PEP) in the NS than in the GET group (10.4% versus 5.7%, respectively; p = 0.105), while the incidence of pneumonia was higher for the GET group. Biliary pancreatitis, contrast injection into the pancreatic duct and an operation time ≥30 min were independent risks factors for PEP. Conclusions ERCP under GET is effective for CBD stone removal, but with slightly higher pneumonia rate after the procedure than non-sedated ERCP.

Abstract
SNAREs are membrane-associated proteins that play a central role in vesicle targeting and intra-cellular membrane fusion reactions in eukaryotic cells. Here we describe the identification of AtBS14a and AtBS14b, putative SNAREs from Arabidopsis thaliana that share 60% amino acid sequence identity. Both AtBS14a and BS14b are dosage suppressors of the temperature-sensitive growth defect in sft1-1 cells and over-expression of either AtBS14a or AtBS14b can support the growth of sft1Delta cells but not bet1Delta cells. These data together with structure-function and biochemical studies presented herein suggest that AtBS14a and AtBS14b share properties that are consistent with them being members of the Bet1/Sft1 SNARE protein family.

Abstract
Sed5p is the only syntaxin family member required for protein transport through the yeast Golgi and it is known to bind up to nine other soluble N-ethylmaleimide-sensitive factor attachment receptor (SNARE) proteins in vivo. We describe in vitro binding experiments in which we identify ternary and quaternary Sed5p-containing SNARE complexes. The formation of SNARE complexes among these endoplasmic reticulum- and Golgi-localized proteins requires Sed5p and is syntaxin-selective. In addition, Sed5p-containing SNARE complexes form selectively and this selectivity is mediated by Sed5p-containing intermediates that discriminate among subsequent binding partners. Although many of these SNAREs have overlapping distributions in vivo, the SNAREs that form complexes with Sed5p in vitro reflect their functionally distinct locales. Although SNARE-SNARE interactions are promiscuous and a single SNARE protein is often found in more than one complex, both the biochemical as well as genetic analyses reported here suggest that this is not a result of nonselective direct substitution of one SNARE for another. Rather our data are consistent with the existence of multiple (perhaps parallel) trafficking pathways where Sed5p-containing SNARE complexes play overlapping and/or distinct functional roles.
