| 2 | Current treatment of ulcerative colitis显示文摘Ulcerative colitis (UC) is a chronic disease featuring re- current inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complica- tions of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice-orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis. | Johannes Meier Andreas Sturm | 2011 | World Journal of Gastroenterology2011,17,27: | 28 |
| 3 | Epithelial restitution and wound healing in inflammatory bowel disease显示文摘Inflammatory bowel disease is characterized by a chronic inflammation of the intestinal mucosa. The mucosal epithelium of the alimentary tract constitutes a key element of the mucosal barrier to a broad spectrum of deleterious substances present within the intestinal lumen including bacterial microorganisms, various dietary factors, gastrointestinal secretory products and drugs. In addition, this mucosal barrier can be disturbed in the course of various intestinal disorders including inflammatory bowel diseases. Fortunately, the integrity of the gastrointestinal surface epithelium is rapidly reestablished even after extensive destruction. Rapid resealing of the epithelial barrier following injuries is accomplished by a process termed epithelial restitution, followed by more delayed mechanisms of epithelial wound healing including increased epithelial cell proliferation and epithelial cell differentiation. Restitution of the intestinal surface epithelium is modulated by a range of highly divergent factors among them a broad spectrum of structurally distinct regulatory peptides, variously described as growth factors or cytokines. Several regulatory peptide factors act from the basolateral site of the epithelial surface and enhance epithelial cell restitution through TGF-β-dependent pathways. In contrast, members of the trefoil factor family (TFF peptides) appear to stimulate epithelial restitution in conjunction with mucin glycoproteins through a TGF-β-independent mechanism from the apical site of the intestinal epithelium. In addition, a number of other peptide molecules like extracellular matrix factors and blood clotting factors and also non- peptide molecules including phospholipids, short-chain fatty acids (SCFA), adenine nucleotides, trace elements and pharmacological agents modulate intestinal epithelial repair mechanisms. Repeated damage and injury of the intestinal surface are key features of various intestinaldisorders including inflammatory bowel diseases and require constant repair of the epithelium. Enhancement of intestinal repair mechanisms by regulatory peptides or other modulatory factors may provide future approaches for the treatment of diseases that are characterized by injuries of the epithelial surface. | Andreas Sturm Axel U Dignass | 2008 | World Journal of Gastroenterology2008,14,3: | 24 |

| 6 | Particle size dependent sinterability and magnetic properties of recycled HDDR Nd-Fe-B powders consolidated with spark plasma sintering显示文摘The dependence of the magnetic properties on the particle size of recycled HDDR Nd-Fe-B powders was investigated,with the aim to assess the reprocessing potential of the end-of-life scrap magnets via spark plasma sintering(SPS).The as received recycled HDDR powder has coercivity(Hci)=830 kA/m and particles in the range from 30 to 700 μm(average 220 μm).After burr milling,the average particle size is reduced to 120 μm and subsequently the Hci of fine(milled) powder was 595 kA/m.Spark plasma sintering was exploited to consolidate the nanograined HDDR powders and limit the abnormal grain coarsening.The optimal SPS-ing of coarse HDDR powder at 750℃for 1 min produces fully dense magnets with Hci=950±100 kA/m which further increases to 1200 kA/m via thermal treatment at 750℃for 15 min.The burr milled fine HDDR powder under similar SPS conditions and after thermal treatment results in Hci=940 kA/m.The fine powder is further sieved down from 630 to less than 50 μm mesh size,to evaluate the possible reduction in Hci in relation to the particle size.The gain in oxygen content doubles for <50 μm sized particles as compared with coarser fractions(>200 μm).The XRD analysis for fractionated powder indicates an increase in Nd2O3 phase peaks in the finer(<100 μm)fractions.Similarly,the Hci reduces from 820 kA/m in the coarse particles(>200 μm) to 460 kA/m in the fine sized particles(<100μm).SPS was done on each HDDR powder fraction under the optimal conditions to measure the variation in Hci and density.The Hci of SPS-ed coarse fraction(>200 μm) is higher than 930 kA/m and it falls abruptly to just 70 kA/m for the fine sized particles(<100 μm).The thermal treatment further improves the Hci to>1000 kA/m only up to 100 μm sized fractions with>90% sintered density.The full densification(>99%) is observed only in the coarse fractions.The loss of coercivity and lack of sinterability in the fine sized particles(<100 μm) are attributed to a very high oxygen content.This implies that during recycling,if good magnetic properties are to be maintained or even increase the HDDR powder particles can be sized down only up to≥100 μm. | Awais Ikram Farhan Mehmood Richard Stuart Sheridan Muhammad Awais Allan Walton Anas Eldosouky Saso Sturm Spomenka Kobe Kristina Zuzek Rozman | 2020 | Journal of Rare Earths2020,38,1: | 5 |

| 11 | MECHANICS OF RELAXING SiGe ISLANDS ON A VISCOUS GLASS显示文摘A process has been developed recently to fabricate a structure com-prising,from top to bottom,a SiGe thin film,a glass layer,and a Si wafer.TheSiGe film is a perfect crystal,and is under biaxial compression.The SiGe film ispatterned into islands.On annealing,the glass flows and the islands relax.Theresulting strain-free islands are used as substrates,to grow epitaxial optoelectronicdevices.This article describes a series of studies on the annealing process,combiningexperiment and theory.A small island relaxes by expansion,starting at the edgesand diffusing to the center.A large island wrinkles before the expansion reaches thecenter.After some time,the wrinkles either disappear,or cause the island to fracture.We model the island as an elastic plate,and the glass layer as a viscous liquid.Thestrains in the islands are measured by X-ray diffraction and Raman spectroscopy,andthe wrinkle amplitudes by atomic force microscope.The data are compared with thetheoretical predictions.We determine the conditions under which the islands relax byexpansion without significant wrinkling,and demonstrate that a cap layer suppresseswrinkles,relaxing a large island crack-free. | R.

| 12 | Parameters of a severe disease course in ulcerative colitis显示文摘AIM:To detect high risk patients with a progressive disease course of ulcerative colitis(UC) requiring immunosuppressive therapy(IT).METHODS:A retrospective,multicenter analysis of 262 UC patients from eight German tertiary inflammatory bowel disease centres was performed.Patients were divided into two groups depending on the patients need to initiate immunosuppressive therapy in the disease course.A comparison between the two groups was made with regard to demographics,clinical and laboratory parameters obtained within three months after UC diagnosis and the response to first medical therapy.Using this data,a prognostic model was established to predict the individual patients probability of requiring an immunosuppressive therapy.RESULTS:In 104(39.7%) out of 262 patients,UC therapy required an immunosuppressive treatment.Patients in this group were significantly younger at time of diagnosis(HR = 0.981 ± 0.014 per year,P = 0.009),and required significantly more often a hospitalisation(HR = 2.5 ± 1.0,P < 0.001) and a systemic corticosteroid therapy at disease onset(HR = 2.4 ± 0.8,P < 0.001),respectively.Response to steroid treatment was significantly different between the two groups of patients(HR = 5.2 ± 3.9 to 50.8 ± 35.6 compared to no steroids,P = 0.016 to P < 0.001).Furthermore,in the IT group an extended disease(HR = 3.5 ± 2.4 to 6.1 ± 4.0 compared to proctitis,P = 0.007 to P = 0.001),anemia(HR = 2.2 ± 0.8,P < 0.001),thrombocytosis(HR = 1.9 ± 1.8,P = 0.009),elevated C-reactive protein(CRP)(HR = 2.1 ± 0.9,P < 0.001),and extraintestinal manifestations in the course of disease(HR = 2.6 ± 1.1,P = 0.004) were observed.Six simple clinical items were used to establish a prognostic model to predict the individual risk requiring an IT.This probability ranges from less than 2% up to 100% after 5 years.Using this,the necessity of an immunosuppressive therapy can be predicted in 60% of patients.Our model can determine the need for an immunosuppressive drug therapy or if a 'watch and wait' approach is reasonable already early in the treatment course of UC.CONCLUSION:Using six simple clinical parameters,we can estimate the patients individual risk of developing a progressive disease course. | Andreas Stallmach Luisa Nickel Thomas Lehmann Bernd Bokemeyer Martin Bürger Dietrich Hüppe Wolfgang Kruis Susanna Nikolaus Jan C Preiss Andreas Sturm Niels Teich Carsten Schmidt | 2014 | World Journal of Gastroenterology2014,20,35: | 2 |
