1Drain amylase value as an early predictor of pancreatic fistula after cephalic duodenopancreatectomy显示文摘AIM:To determine predictors of clinically relevant pancreatic fistulas(CRPF)by measuring drain fluid amylase(DFA)in the early postoperative period.METHODS:This prospective clinical study included382 patients with periampullary tumors that were surgically resected at our department between March 2005and October 2012.A cephalic duodenopancreatectomy (DP)was performed on all patients.Two closed suction drains were placed at the end of the surgery.The highest postoperative DFA value was recorded and analyzed during the first three postoperative days and on subsequent days if the drains were kept longer.Pancreatic fistula(PF)was classified according to the International Study Group of Pancreatic Fistula(ISGPF)criteria.Postoperative complications were defined according to the Dindo-Clavien classification.All data were statistically analyzed.The optimal thresholds of DFA levels on the first,second and third postoperative days were estimated by constructing receiver operating curves,generated by calculating the sensitivities and specificities of the DFA levels.The DFA level limits were used to differentiate between the group without PF and the groups with biochemical pancreatic fistula(BPF)and CRPF.RESULTS:Pylorus-preserving duodenopancreatectomy was performed on 289(75.6%)patients,while the remaining patients underwent a classic Whipple procedure(CW).The total incidence of PF was 37.7%(grade A22.8%,grade B 11.0%and grade C 3.9%).Soft pancreatic texture(SPT)was present in 58.3%of patients who developed PF.Mortality was 4.2%.The median DFA value on the first postoperative day(DFA1)in patients who developed PF was 4520 U/L(range 350-99000 U/L)for grade A fistula(BPF)with a SPT and a diameter of the main pancreatic duct(MPD)of≤3 mm.For grade B/C(CRPF),the median DFA1 value was 8501 U/L(range377-92060 U/L)with a SPT and MPD of≤3 mm.These values were significantly higher when compared to the patients who did not have PF(122;range 5-37875 U/L).The upper limit of DFA values for the first 3 postoperative days in the examined stages of PF were:DFA1 1200U/L for the BPF and CRPF;DFA3 350 U/L for BPF and DFA3 800 U/L for CRPF.The determined values were highly significant and demonstrated a reliable diagnostic test for both BPF and CRPF.CONCLUSION:DFA1≥1200 U/L is an important predictive factor for PF of any degree.The trend of DFA3(decrease of<50%)compared to DFA1 is a significant factor in the differentiation of CRPF from transient BPF.Vladimir D Dugalic Djordje M Knezevic Vladan N Obradovic Miroslava G Gojnic-Dugalic Slavko V Matic Aleksandra R Pavlovic-Markovic Predrag D Dugalic Srbislav M Knezevic 2014World Journal of Gastroenterology2014,20,26:7
2New frontiers for the materials genome initiative显示文摘The Materials Genome Initiative(MGI)advanced a new paradigm for materials discovery and design,namely that the pace of new materials deployment could be accelerated through complementary efforts in theory,computation,and experiment.Along with numerous successes,new challenges are inviting researchers to refocus the efforts and approaches that were originally inspired by the MGI.In May 2017,the National Science Foundation sponsored the workshop“Advancing and Accelerating Materials Innovation Through the Synergistic Interaction among Computation,Experiment,and Theory:Opening New Frontiers”to review accomplishments that emerged from investments in science and infrastructure under the MGI,identify scientific opportunities in this new environment,examine how to effectively utilize new materials innovation infrastructure,and discuss challenges in achieving accelerated materials research through the seamless integration of experiment,computation,and theory.This article summarizes key findings from the workshop and provides perspectives that aim to guide the direction of future materials research and its translation into societal impacts.Juan J.de Pablo Nicholas E.Jackson Michael A.Webb Long-Qing Chen Joel E.Moore Dane Morgan Ryan Jacobs Tresa Pollock Darrell G.Schlom Eric S.Toberer James Analytis Ismaila Dabo Dean M.DeLongchamp Gregory A.Fiete Gregory M.Grason Geoffroy Hautier Yifei Mo Krishna Rajan Evan J.Reed Efrain Rodriguez Vladan Stevanovic Jin Suntivich Katsuyo Thornton Ji-Cheng Zhao 2019npj Computational Materials2019,,1:7
3Transepithelial transport of putrescine across monolayers of the human intestinal epithelial cell line, Caco-2显示文摘AIM To study the transepithelial transport characteristics of the polyamine putrescine in human intestinal Caco-2 cell monolayers to elucidate the mechanisms of the putrescine intestinal absorption.METHODS The transepithelial transport and the cellular accumulation of putrescine was measured using Caco 2 cell monolayers grown on permeable filters.RESULTS Transepithelial transport of putrescine in physiological concentrations (>0.5 mM)from the apical to basolateral side was linear. Intracellular accumulation of putrescine was higher in confluent than in fully differentiated Caco-2 cells, but still negligible (less than 0.5%) of the overall transport across the monolayers in apical-to-basolateral direction. EGF enhanced putrescine accumulation in Caco-2 cells by four-fold, as well as putrescine conversion to spermidine and spermine by enhancing the activity of Sadenosylmethionine decarboxylase. However,EGF did not have any significant influence on putrescine flux across the Caco-2 cell monolayers. Excretion of putrescine from Caco-2cells into the basolateral medium did not exceed 50 picomoles, while putrescine passive flux from the apical to the basolateral chamber,contributed hundreds of micromoles polyamines to the basolateral chamber.CONCLUSION Transepithelial transport of putrescine across Caco-2 cell monolayers occurs in passive diffusion, and is not influenced when epithelial cells are stimulated to proliferate by a potent mitogen such as EGF.Vladan Milovic Lyudmila Turchanowa Jürgen Stein Wolfgang F.Caspary 2001World Journal of Gastroenterology2001,7,2:5
