1One hundred and one over-the-scope-clip applications forsevere gastrointestinal bleeding,leaks and fistulas显示文摘AIM: To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip(OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas.METHODS: From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients(48.8%) presented with severe upper-gastrointestinal(GI) bleeding, 3(3.6%) patients with lower-GI bleeding, 7 patients(8.3%) underwent perforation closure, 18 patients(21.4%) had prevention of secondary perforation, 12 patients(14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection(ESD) and 3 patients(3.6%) had an intervention on a chronic fistula. RESULTS: In 78/84 patients(92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients(89.28%). The overall mortality in the study patients was 11/84(13.1%) and was seen in patients with life threatning upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41(85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases(57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18(100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen(2%).CONCLUSION: This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.Edris Wedi Susana Gonzalez Detlev Menke Elena Kruse Kai Matthes Juergen Hochberger 2016World Journal of Gastroenterology2016,22,5:28
2Chemokine expression in hepatocellular carcinoma versus colorectal liver metastases显示文摘AIM: To evaluate and compare the expression profiles of CXCL12 (SDF-1), CCL19 (MIP-3β), CCL20 (MIP-3α) and CCL21 (6Ckine, Exodus2) and their receptors on RNA and protein levels in hepatocellular carcinoma (HCC) versus colorectal liver metastases (CRLM) and to elucidate their impact on the carcinogenesis and progression of malignant liver diseases. METHODS: Chemokine expression was analyzed by RT-PCR and ELISA in 11 cases of HCC specimens and in 23 cases of CRLM and corresponding adjacent non- tumorous liver tissues, respectively. Expressions of their receptors CXCR4, CCR6 and CCR7 were analyzed by RT- PCR and Western blot analysis in the same cases of HCC and CRLM. RESULTS: Significant up-regulation for CCL20/CCR6 was detected in both cancer types. Moreover, CCL20 demonstrated significant overexpression in CRLM in relation to the HCC tissues. Being significantly up- regulated only in CRLM, CXCR4 displayed an aberrant expression pattern with respect to the HCC tissues. CONCLUSION: Correlation of CXCR4 expression with CRLM suggests CXCR4 as a potential predictive factor for CRLM. High level expression of CCL20 and its receptor CCR6 in HCC and CRLM with marked up- regulation of CCL20 in CRLM in relation to HCC tissues indicates involvement of the CCL20/CCR6 ligand-receptor pair in the carcinogenesis and progression of hepatic malignancies.Claudia Rubie Vilma Oliveira Frick Mathias Wagner Christina Weber Bianca Kruse Katja Kempf Jochen Knig Bettina Rau Martin Schilling 2006World Journal of Gastroenterology2006,12,41:24

4管线直接铺设技术显示文摘管线直接铺设技术借助“管道推进器”(Pipe Thruster)的连续推进,单向连续地将预制管线铺设到位。如同顶管法一样,土体挖掘作业仍通过与管线相连的微型隧道掘进机来完成,开挖面通过泥浆维持,通常用膨润土泥浆。由于新方法的成功,已在几个工程中得以应用。管道推进器所产生的推力是直接铺管工程设计时考虑的一个重要M题。本文利用ABAQUS软件包里的有限元法分析了将管线推入钻孔时所需要的力及相关因素。对有限元法计算结果的分析表明这几种因素之间具有强烈的相互影响。而且,根据这些因素和管段受力分析得出了推力计算公式,并将最近几个工程中测量出的推进力与根据这些计算公式的计算值进行了对比。结果袁明,摩擦系数E和£应分别取为100Pa和0.3,推力设计值应将计算出的推力值乘以1.5倍的安全系数。这个安全系数主要是考虑到在停顿期会有2.5%的概率超过上述计算值后提出的。Pruiksma J.

5General review of magnetic resonance elastography显示文摘Magnetic resonance elastography(MRE) is an innovative imaging technique for the non-invasive quantification of the biomechanical properties of soft tissues via the direct visualization of propagating shear waves in vivo using a modified phase-contrast magnetic resonance imaging(MRI) sequence. Fundamentally,MRE employs the same physical property that physicians utilize when performing manual palpation- that healthy and diseased tissues can be differentiated on the basis of widely differing mechanical stiffness. By performing 'virtual palpation ',MRE is able to provide information that is beyond the capabilities of conventional morphologic imaging modalities. In an era of increasing adoption of multi-parametric imaging approaches for solving complex problems,MRE can be seamlessly incorporated into a standard MRI examination to provide a rapid,reliable and comprehensive imaging evaluation at a single patient appointment. Originally described by the Mayo Clinic in 1995,the technique represents the most accurate non-invasive method for the detection and staging of liver fibrosis and is currently performed in more than 100 centers worldwide. In this general review,the mechanical properties of soft tissues,principles of MRE,clinical applications of MRE in the liver and beyond,and limitations and future directions of this discipline-are discussed. Selected diagrams and images are provided for illustration.Gavin Low Scott A Kruse David J Lomas 2016World Journal of Radiology2016,8,1:5

7Cobalt–copper based catalysts for higher terminal alcohols synthesis via Fischer–Tropsch reaction显示文摘The production of higher terminal alcohols through CO hydrogenation according to the Fischer–Tropsch(F–T) process has been a topic of interest since the Institut Fran?ais du Pétrole(IFP) demonstrated shortchain C_1–C_6mixed alcohols production over cobalt–copper based catalysts. A number of catalyst formulations were screened for their suitability at that time. In particular, the addition of Cr, Zn, Al, Mn and V to Co Cu was investigated. In a number of patents, it was shown that catalyst preparation is crucial in these catalyst formulations and that high alcohols selectivity can only be achieved by carefully respecting the procedures and recipes. This short critical review highlights recent developments in Co Cu-based catalysts for higher terminal alcohols synthesis via F–T synthesis. Special attention will be given to catalyst preparation which according to developments in our group is based on oxalate precipitation. This way we show that the close association of Co and Cu on the one hand and promoter/dispersant on the other are of utmost importance to ensure high performance of the catalysts. We shall concentrate on 'Co Cu Mn','Co Cu Mo' and 'Co Cu Nb' catalyst formulations, all prepared via oxalate precipitation and combined with'entrainment techniques' if necessary, and show high total alcohols selectivity can be obtained with tunable Anderson-Schulz-Flory chain-lengthening probability. Either long-chain C_8–C_(14)terminal alcohols as feedstock for plasticizers, lubricants and detergents, or short-chain C_2–C_5alcohols as 'alkanol' fuels or fuel additives can be formed this way.Yizhi Xiang Norbert Kruse 2016Journal of Energy Chemistry2016,25,6:4
8Effect of process parameters on additive-free electrospinning of regenerated silk fibroin nonwovens显示文摘Silk fibroin is a biomaterial with multiple beneficial properties for use in regenerative medicine and tissue engineering.When dissolving and processing the reconstituted silk fibroin solution by electrospinning,the arrangement and size of fibers can be manifold varied and according fiber diameters reduced to the nanometer range.Such nonwovens show high porosity as well as potential biocompatibility.Usually,electrospinning of most biomaterials demands for the application of additives,which enable stable electrospinning by adjusting viscosity,and are intended to evaporate during processing or to be washed out afterwards.However,the use of such additives increases costs and has to be taken into account in terms of biological risks when used for biomedical applications.In this study,we explored the possibilities of additive-free electrospinning of pure fibroin nonwovens and tried to optimize process parameters to enable stable processing.We used natural silk derived from the mulberry silkworm Bombyx mori.After degumming,the silk fibroin was dissolved and the viscosity of the spinning solution was controlled by partial evaporation of the initial solving agent.This way,we were able to completely avoid the use of additives and manufacture nonwovens,which potentially offer higher biocompatibility and reduced immunogenicity.Temperature and relative humidity during electrospinning were systematically varied(25–35°C,25–30%RH).In a second step,the nonwovens optionally underwent methanol treatment to initiate beta-sheet formation in order to increase structural integrity and strength.Comprehensive surface analysis on the different nonwovens was performed using scanning electron microscopy and supplemented by additional mechanical testing.Cytotoxicity was evaluated using BrdU-assay,XTT-assay,LDH-assay and live-dead staining.Our findings were,that an increase of temperature and relative humidity led to unequal fiber diameters and defective nonwovens.Resistance to penetration decreased accordingly.The most uniform fiber diameters of 998±63 nm were obtained at 30°C and 25%relative humidity,also showing the highest value for resistance to penetration(0.20 N).The according pure fibroin nonwoven also showed no signs of cytotoxicity.However,while the biological response showed statistical evidence,the material characteristics showed no statistically significant correlation to changes of the ambient conditions within the investigated ranges.We suggest that further experiments should explore additional ranges for temperature and humidity and further focus on the repeatability of material properties in dependency of suitable process windows.Alexander Kopp Ralf Smeets Martin Gosau Nadja Kröger Sandra Fuest Marius Köpf Magnus Kruse Judith Krieger Rico Rutkowski Anders Henningsen Simon Burg 2020Bioactive Materials2020,5,2:3

13Dynamic simulation and experimental validation of a two-phase closed thermosyphon for geothermal application显示文摘The heat transfer perfonmance of a vertical two-phase closed thermosyphon(TPCT)used in a geothermal heat pump was experimentally investigated.The TPCT is a verticalplain steel pipe with inner diameter of 114 mm and bored 368 m deep underground.Carbon dioxide(CO_(2))is used as working fluid.In the TPCT there is no condensation section.CO_(2)is condensed by the evaporator pf the heat pump,flows into the head of the TPCT and nuns down as a falling film along the inner wall of the pipe.For the heat transfer simulation in the TPCT,a quasi-dynamic model in which the mass transfer between the liquid and vapor phases as well as the conduction heat transfer from the surrounding soil towards the pipe is treated dynamically.However the film flow modeling is based on the Nusselt theory of frilm condenssation.The compauison of the experimental data with the numerical simulation is presented and discussed.Johann-Christoph Ebeling Xing Luo Stephan Kabelac Sebastian Luckmann Horst Kruse 2017Propulsion and Power Research2017,6,2:2
14Irritable bowel syndrome and chronic pelvic pain: A singular or two different clinical syndrome?显示文摘Irritable bowel syndrome (IBS) and chronic pelvic pain (CPP) are both somatoform disorders with a high prevalence within the population in general. The objective was to compare both entities, to fi nd the differences and the similarities related to epidemiology and psychosocial aspects like stressful life events, physical and sexual abuse, illness behaviour and comorbidity. The technical literature was reviewed systematically from 1971 to 2006 and compared. According to literature, IBS and CPP seem to be one rather than two different entities with the same localisation of pain. Both syndromes also are similar concerning prevalence, the coexistence of mental and somatoform disorders, the common history of sexual and physical abuse in the past and their health care utilization. It could be shown that there were many similarities between IBS and CPP. Nevertheless both are traded as different clinical pictures as far. Therefore it seems to be reasonable and necessary to generate a common diagnosis algorithm and to bring gynaecologists and gastroenterologists into dialogue.Anna Matheis Ute Martens Johannes Kruse Paul Enck 2007World Journal of Gastroenterology2007,13,25:2
