/carboxyl hydrogen bonds (and stronger) are sufficiently strong enough to facilitate antibody-mediated trapping; weaker hydroxyl/hydroxyl bonds or hydroxyl/amine bonds fail to adequately slow particles. Our findings presents the first blueprint for how to engineer de novo biogels that are capable of harnessing antibodies to immobilize foreign entities in the biogels, for applications ranging from infectious disease to contraception to purification processes. Interleukin-3 (IL-3), IL-5, and granulocyte-macrophage colony-stimulating factor (GM-CSF) are related cytokines that signal through receptors possessing the β common (βc) chain. As a family, these cytokines combine rather non-specific hematopoietic growth factor properties with a special importance for eosinophils, basophils, and mast cells. In fish the cytokines of this family are called IL-5fam, and the present study, using carp, constitutes their first functional analysis. Carp il-5fam expression was enhanced by stimulation with phytohemagglutinin and killed bacteria. Reminiscent of mammalian IL-3/IL-5/GM-CSF family members, recombinant carp IL-5fam (rcIL-5fam) induced activation of transcription factor STAT5 and efficiently promoted proliferation and colony-formation of eosinophil/basophil/mast-cell type (EBM) granulocytes. Upon addition of recombinant carp βc the growth effect of rcIL-5fam was reduced, suggesting βc participation in the signaling route. In summary, despite differences in individual cytokines and cell populations, fish and mammalian IL-3/IL-5/GM-CSF family members share growth factor functions for non-neutrophil granulocytes. Viral glycoproteins are expressed by many viruses, and during infection they usually play very important roles, such as receptor attachment or membrane fusion. The mature virion of the white spot syndrome virus (WSSV) is unusual in that it contains no glycosylated proteins, and there are currently no reports of any glycosylation mechanisms in the pathogenesis of this virus. In this study, we cloned a glycosylase, mannosyl-glycoprotein endo-β-N-acetylglucosaminidase (ENGase, EC 3.2.1.96), from Penaeus monodon and found that it was significantly up-regulated in WSSV-infected shrimp. learn more A yeast two-hybrid assay showed that PmENGase interacted with both structural and non-structural proteins, and GST-pull down and co-immunoprecipitation (Co-IP) assays confirmed its interaction with the envelope protein VP41B. In the WSSV challenge tests, the cumulative mortality and viral copy number were significantly decreased in the PmEngase-silenced shrimp, from which we conclude that shrimp glycosylase interacts with WSSV in a way that benefits the virus. Lastly, we speculate that the deglycosylation activity of PmENGase might account for the absence of glycosylated proteins in the WSSV virion. OBJECTIVE To investigate the impact of a dedicated weekly administrative hour on case logging, duty hour reporting, and duty hour violations. DESIGN Retrospective analyses of 2 timeframes pre-implementation and post-implementation of a dedicated weekly administrative hour in a surgical residency were assessed for changes in duty hour reporting, case logging, and duty hour violations. The preimplementation period spanned from July 2011 to June 2014 and the postimplementation period from July 2014 to June 2017. SETTING Community-based, university-affiliated hospital. PARTICIPANTS A total of 79 surgical residents were included over a 6-year period. The subjects worked before and after the implementation of a weekly dedicated administrative time. RESULTS Seven and 30-day procedure logging rates improved from 28.7% to 37.2% and 52.7% to 69.9%, respectively (p less then 0.001). PGY 1 residents showed a significant increase in procedures logged within 7 days during the postimplementation period. PGY 1, PGY 2 and PGY 3 all showed a significant increase in procedures logged within 30 days during the postimplementation period. Seven and 30-day duty hour completion rates increased postimplementation from 7.8% to 9.2% (p less then 0.001) and 64.7% to 67.3% (p less then 0.001), respectively. Duty hour violations decreased in the postimplementation time frame (40.6% vs 29.2%, p less then 0.001). Duty hour violations were more common in earlier years of training. PGY 1 were 15.6 times more likely to have an 80 hours. per week violation than a PGY5 (OR 15.1; 95% CI 2.1-118.0). CONCLUSIONS Procedural logging and duty hour compliance improved after implementation of a dedicated weekly time for administrative duties. The year of a resident in training is related to compliance with logging and may impact the incidence of duty hour violations. Residents reported significantly fewer duty hour violations, however this may be multifactorial. OBJECTIVE Transurethral resection of the bladder tumour (TURBT) is one the most common urological procedures. It is also one the fundamental surgeries performed by residents. The learning curve (LC) for TUR has never been analysed. The aim of the study was to analyse the learning curve of TURBT in a residency setting. DESIGN, SETTING AND PARTICIPANTS This retrospective multicentre analysis of prospectively maintained databases enrolled 993 consecutive TURBTs performed by 10 urology residents in 3 academic institutions. Study end-points were as follows the absence of muscularis propria in a specimen, any intra- or postoperative surgical complication and 3-month recurrence-free survival. RESULTS With increasing experience, residents operated more complex cases defined by higher rate of large, multifocal or high-risk tumours. In the same time, surgery time, postoperative catheterization time and hospital stay became shorter. An improvement has been noticed regarding the muscularis propria sampling and 3-month recurrence-free survival, but not regarding the risk of surgical complications. Evident improvement in study end-points was noticed after 101 operations; surgeons achieved the best clinical outcomes after performing 170 procedures, whereas the poorest results for the first 45 operations. CONCLUSIONS TURBT has a flat LC with 100 cases being the absolute minimum for a resident in training to achieve acceptable oncological and surgical outcomes.
