| 1 | Screening pre-bariatric surgery patients for esophageal disease with esophageal capsule endoscopy显示文摘AIM:To determine if esophageal capsule endoscopy(ECE)is an adequate diagnostic alternative to esophagogastroduodenoscopy(EGD)in pre-bariatric surgery patients.METHODS:We conducted a prospective pilot study to assess the diagnostic accuracy of ECE(PillCam ESO2,Given Imaging)vs conventional EGD in pre-bariatric surgery patients.Patients who were scheduled for bariatric surgery and referred for pre-operative EGD were prospectively enrolled.All patients underwent ECE followed by standard EGD.Two experienced gastroenterologists blinded to the patient’s history and the findings of the EGD reviewed the ECE and documented their findings.The gold standard was the findings on EGD.RESULTS:Ten patients with an average body mass index of 50 kg/m2were enrolled and completed the study.ECE identified 11 of 14(79%)positive esophageal/gastroesophageal junction(GEJ)findings and 14of 17(82%)combined esophageal and gastric findings identified on EGD.Fisher’s exact test was used to compare the findings and no significant difference was found between ECE and EGD(P=0.64 for esophageal/GEJ and P=0.66 for combined esophageal and gastric findings respectively).Of the positive esophageal/GEJ findings,ECE failed to identify the following:hiatal hernia in two patients,mild esophagitis in two patients,and mild Schatzki ring in two patients.ECE was able to identify the entire esophagus in 100%,gastric cardia in0%,gastric body in 100%,gastric antrum in 70%,pylorus in 60%,and duodenum in 0%.CONCLUSION:There were no significant differences in the likelihood of identifying a positive finding using ECE compared with EGD in preoperative evaluation of bariatric patients. | Ashish Shah Erica Boettcher Marianne Fahmy Thomas Savides Santiago Horgan Garth R Jacobsen Bryan J Sandler Michael Sedrak Denise Kalmaz | 2013 | World Journal of Gastroenterology2013，19，37： | 7 |
| 2 | Ternary Ni-Co-Fe oxyhydroxide oxygen evolution catalysts:Intrinsic activity trends,electrical conductivity,and electronic band structure显示文摘Nickel-,cobalt-,and iron-based(oxy)hydroxides comprise the most-commonly studied electrocatalysts for the oxygen-evolution reaction(OER)in alkaline solution.A fundamental understanding of composition-structure-activity relationships for mixed-metal Ni-Co and Ni-Co-Fe(oxy)hydroxides is important to guide the design of advanced OER catalysts.Here we use cyclic voltammetry,chronopotentiometry,inductively-coupled plasma-optical emission spectroscopy,and in situ electrical conductivity measurements to characterize the properties and activity of various compositions of Ni-Co-Fe(oxy)hydroxides prepared by cathodic co-electrodeposition.Consistent with previous studies,we find Fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER activity.In the rigorous absence of Fe(achieved by using specially cleaned electrolytes),the most-active Ni-Co(oxy)hydroxide composition has an OER turn-over frequency only twice that ofpure Co(oxy)hydroxide,suggesting minimal synergism between the two metals.The addition of Co to Ni-Fe(oxy)hydroxides shifts the onset of electrical conductivity to lower potentials,but has little effect on the intrinsic OER activity,with the most-active Ni-Co-Fe(oxy)hydroxide having an OER turn-over frequency only -1.5 times that of the Ni-Fe(oxy)hydroxides.The magnitudes of the electrical conductivities are similar for all the compositions measured.Density-functional-theory-calculated projected density of states show a significant contribution of all chemical elements at the valence band edge of the mixed-metal oxyhydroxide electronic structure,demonstrating significant electronic hybridization between the elements.The calculations suggest the involvement of all the elements in modulating the electronic structure at putative Fe-based active sites that are probably located at edges or defects in the two-dimensional oxyhydroxide sheets. | Michaela Burke Stevens Lisa J.
