AIM： To correlate the significance of liver biochemical tests in diagnosing post orthotopic liver transplantation （OLT） biliary complications and to study their profile before and after endoscopic therapy.METHODS： Patients who developed biliary complications were analysed in detail for the clinical information, laboratory tests, treatment offered, response to it, follow up and outcomes. The profile of liver enzymes was determined. The safety, efficacy and outcomes of endoscopic retrograde cholangiography （ERC） were also analysed. RESULTS： 40 patients required ERC for 70 biliary complications. GGT was found to be 〉 3 times （388.1 ± 70.9 U/mL vs 168.5 4± 34.2 U/L, P = 0.007） and SAP 〉 2 times （345.1 ± 59.1 U/L vs 152.7 ± 21.4 U/L, P = 0.003） the immediate post OLT values. Most frequent complication was isolated anastomotic res in 28 （40%）. Sustained success was achieved in 26 （81%） patients. CONCLUSION： Biliary complications still remain an important problem post OLT. SAP and GGT can be used as early, non-invasive markers for diagnosis and also to assess the adequacy of therapy. Endoscopic management is usually effective in treating the majority of these biliary complications.

The present investigation analyzes the effects of major geometrical modifications to the interior of a convectioncooled gas turbine rotor blade. The main focus lies on the flow of the leading edge channels and the impact on theheat transfer. An experimental approach is performed with flow visualization via paint injection into water. Alsonumerical calculations are carried out in two sets, on the one hand water calculations accompanying the experimentsand on the other hand conjugate heat transfer calculations under realistic engine conditions. The latter calculationsare still ongoing delivering preliminary *** geometry configurations are investigated, three of them with differing turbulator arrangements in the leadingedge channels. The operating point of the base configuration is set to Re = 50,000 at the inlet while for the modifiedgeometries the pressure ratio is held constant compared to the *** several investigated configurations one could be identified that leads to a heat transfer enhancement inone leading edge channel 7 % larger compared to the base.

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 *** 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 *** with previous studies,we find fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER *** 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 *** 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)*** magnitudes of the electrical conductivities are similar for all the compositions ***-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 *** 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.

消化性溃疡的发生与许多因素有关,通常认为是由于胃腔内攻击因素和保护/修复因素失去平衡所致,传统将胃酸视为最重要的攻击因素,因此,迄今的治疗主要是通过中和的方法(如抗酸药物)或药物抑制胃酸分泌(H_2受体拮抗剂、质子泵抑制剂)来降低胃酸。近年人们的观念发生了改变,幽门螺杆菌(HP)感染被视为是最重要的致病因子,因此,十二指肠溃疡可能是一种纯粹感染性疾病。
