| 1 | 2010年世界胃肠病学组织关于炎症性肠病诊断和治疗的实践指南显示文摘炎症性肠病(IBD)是一组特发性、慢性、炎症性肠道疾病状态,包括两种主要类型:克罗恩病(CD)和溃疡性结肠炎(UC),两者的临床和病理特征既有重叠又有区别。IBD过去常见于发达国家,近几十年,发展中国家的患病率逐步上升。本指南就IBD诊断和治疗方面提出的独特议题在当前的文献和指南中几乎从未被提及。由于各地区的IBD临床特点差异较大,因此根据患者的主诉诊断IBD或评估疾病活动度需随地区的变化而变化。同样,治疗亦应根据疾病的分类和当地医疗资源进行调整。世界胃肠病学组织根据世界各国医疗资源的差异,采用级联方法制订了IBD的诊疗指南。 | Charles N.Bernstein Michael Fried J.H.Krabshuis Henry Cohen R.Eliakim Suleiman Fedail Richard Gearry K.L.Goh Saheed Hamid Aamir Ghafor Khan A.W.LeMair Malfertheiner Qin Ouyang J.F.Rey Ajit Sood Flavio Steinwurz Ole O.Thomsen Alan Thomson Gillian Watermeyer 杨钊斌 杨川华 钱本余 | 2010 | 胃肠病学2010,15,9: | 101 |
| 2 | Detection of tumor stem cell markers in pancreatic carcinoma cell lines显示文摘BACKGROUND: Cancer of the pancreas is the fourth leading cause of cancer death in industrialized countries. In malignancy, actively proliferating cells may be effectively targeted and killed by anti-cancer therapies, but stem cells may survive and support re-growth of the tumor. Thus, new strategies for the treatment of cancer clearly will also have to target cancer stem cells. The goal of the present study was to determine whether pancreatic carcinoma cell growth may be driven by a subpopulation of cancer stem cells. Because previous data implicated ABCG2 and CD133 as stem cell markers in hematopoietic and neural stem/progenitor cells, we analyzed the expression of these two proteins in pancreatic carcinoma cell lines. METHODS: Five established pancreatic adenocarcinoma cell lines were analyzed. Total RNA was isolated and real- time RT-PCR was performed to determine the expression of ABCG2 and CD133. Surface expression of ABCG2 and CD133 was analyzed by flow cytometric analysis. RESULTS: All pancreatic carcinoma cell lines tested expressed significantly higher levels of ABCG2 than non-malignant fibroblasts or two other malignant non- pancreatic cell lines, i.e., SaOS2 osteosarcoma and SKOV3 ovarian cancer. Elevated CD133 expression was found in two out of five pancreatic carcinoma cell lines tested. Using flow cytometric analysis we confirmed surface expression of ABCG2 in all five lines. Yet, CD133 surface expression was detectable in the two cell lines, A818-6 and PancTu1, which exhibited higher mRNA levels.CONCLUSIONS: Two stem cell markers, ABCG2 and CD133 are expressed in pancreatic carcinoma cell lines. ABCG2 and/or CD133 positive cells may represent subpopulation of putative cancer stem cells also in this malignancy. Because cancer stem cells are thought to be responsible for tumor initiation and its recurrence after an initial response to chemotherapy, they may be a very promising target for new drug developments. | Monika Olempska Patricia Alice Eisenach Ole Ammerpohl Hendrik Ungefroren Fred Fandrich Holger Kalthoff | 2007 | Hepatobiliary & Pancreatic Diseases International2007,6,1: | 69 |
| 3 | Inflammatory pathways of importance for management of inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD)is a group of chronic disorders of the gastrointestinal tract comprising Crohn’s disease(CD)and ulcerative colitis(UC).Their etiologies are unknown,but they are characterised by an imbalanced production of pro-inflammatory mediators,e.g.,tumor necrosis factor(TNF)-α,as well as increased recruitment of leukocytes to the site of inflammation.Advantages in understanding the role of the inflammatory pathways in IBD and an inadequate response to conventional therapy in a large portion of patients,has over the last two decades lead to new therapies which includes the TNF inhibitors(TNFi),designed to target and neutralise the effect of TNF-α.TNFi have shown to be efficient in treating moderate to severe CD and UC.However,convenient alternative therapeutics targeting other immune pathways are needed for patients with IBD refractory to conventional therapy including TNFi.Indeed,several therapeutics are currently under development,and have shown success in clinical trials.These include antibodies targeting and neutralising interleukin-12/23,small pharmacologic Janus kinase inhibitors designed to block intracellular signaling of several pro-inflammatory cytokines,antibodies targeting integrins,and small anti-adhesion molecules that block adhesion between leukocytes and the intestinal vascular endothelium,reducing their infiltration into the inflamed mucosa.In this review we have elucidated the major signaling pathways of clinical importance for IBD therapy and highlighted the new promising therapies available.As stated in this paper several new treatment options are under development for the treatment of CD and UC,however,no drug fits all patients.Hence,optimisations of treatment regimens are warranted for the benefit of the patients either through biomarker establishment or other rationales to maximise the effect of the broad range of mode-of-actions of the present and future drugs in IBD. | Jannie Pedersen Mehmet Coskun Christoffer Soendergaard Mohammad Salem Ole Haagen Nielsen | 2014 | World Journal of Gastroenterology2014,20,1: | 28 |
| 4 | 采用波纹管测试水泥基材料早期自收缩方法显示文摘用特制的波纹管模具,可以在塑性阶段以水平方向测长度的方式将体积应变转换为长度应变来测量,不仅能实现自浇注成型开始对水泥基材料自收缩的连续监测,而且可以有效避免重力、温度变化以及模具约束对于测试结果的影响。介绍了波纹管测长度的原理,研究了波纹管的材质、尺寸和内部空气对于测试结果的影响。结果表明:测试结果受到波纹管材质、尺寸和成型引入空气的影响;随着波纹管内试件的刚度不断增加,其影响程度也随之减小,到终凝10 h后这种影响可以忽略不计。 | 田倩 JENSEN Ole Mejlhede | 2009 | 硅酸盐学报2009,37,1: | 22 |
| 5 | miR-20b, miR-98, miR-125b-1*, and let-7e* as new potential diagnostic biomarkers in ulcerative colitis显示文摘AIM:To use microarray-based miRNA profiling of colonic mucosal biopsies from patients with ulcerative colitis (UC), Crohn's disease (CD), and controls in order to identify new potential miRNA biomarkers in inflammatory bowel disease. METHODS:Colonic mucosal pinch biopsies from the descending part were obtained endoscopically from patients with active UC or CD, quiescent UC or CD, as well as healthy controls. Total RNA was isolated and miRNA expression assessed using the miRNA microarray Geniom Biochip miRNA Homo sapiens (Febit GmbH, Heidelberg, Germany). Data analysis was carried out by principal component analysis and projection to latent structure-discriminant analysis using the SIMCA-P+12 software package (Umetrics, Umea, Sweden). The microarray data were subsequently validated by quantitative real-time polymerase chain reaction (qPCR) performed on colonic tissue samples from active UC patients (n = 20), patients with quiescent UC (n = 19), and healthy controls (n = 20). The qPCR results were analyzed with Mann-WhitneyU test.In silico prediction analysis were performed to identify potential miRNA target genes and the predicted miRNA targets were then compared with all UC associated susceptibility genes reported in the literature. RESULTS:The colonic mucosal miRNA transcriptome differs significantly between UC and controls, UC and CD, as well as between UC patients with mucosal inflammation and those without. However, no clear differences in the transcriptome of patients with CD and controls were found. The miRNAs with the strongest differential power were identified (miR-20b, miR-99a, miR-203, miR-26b, and miR-98) and found to be upregulated more than a 10-fold in active UC as compared to quiescent UC, CD, and controls. Two miRNAs, miR-125b-1* and let-7e*, were up-regulated more than 5-fold in quiescent UC compared to active UC, CD, and controls. Four of the seven miRNAs (miR-20b, miR-98, miR-125b-1*, and let-7e*) were validated by qPCR and found to be specifically upregulated in patients with UC. Usingin silico analysis we found several predicted pro-inflammatory target genes involved in various pathways, such as mitogen-activated protein kinase and cytokine signaling, which are both key signaling pathways in UC.CONCLUSION:The present study provides the first evidence that miR-20b, miR-98, miR-125b-1*, and let7e* are deregulated in patients with UC. The level of these miRNAs may serve as new potential biomarkers for this chronic disease. | Mehmet Coskun Jacob Tveiten Bjerrum Jakob Benedict Seidelin Jesper Thorvald Troelsen JΦrgen Olsen Ole Haagen Nielsen | 2013 | World Journal of Gastroenterology2013,19,27: | 19 |
| 6 | MicroRNAs in inflammatory bowel disease-pathogenesis,diagnostics and therapeutics显示文摘The pathogenesis of inflammatory bowel disease (IBD) is complex and largely unknown. Until recently, research has focused on the study of protein regulators in inflammation to reveal the cellular and molecular networks in the pathogenesis of IBD. However, in the last few years, new and promising insights have been generated from studies describing an association between an altered expression of a specific class of non-coding RNAs, called microRNAs (miRs or miRNAs) and IBD. The short (approximately 22 nucleotides), endogenous, single-stranded RNAs are evolutionary conserved inanimals and plants, and regulate specific target mRNAs at the post-transcriptional level. MiRNAs are involved in several biological processes, including development, cell differentiation, proliferation and apoptosis. Furthermore, it is estimated that miRNAs may be responsible for regulating the expression of nearly one-third of the genes in the human genome. Thus, miRNA deregulation often results in an impaired cellular function, and a disturbance of downstream gene regulation and signaling cascades, suggesting their implication in disease etiology. Despite the identification of more than 1900 mature human miRNAs, very little is known about their biological functions and functional targets. Recent studies have identified dysregulated miRNAs in tissue samples of IBD patients and have demonstrated similar differences in circulating miRNAs in the serum of IBD patients. Thus, there is great promise that miRNAs will aid in the early diagnosis of IBD, and in the development of personalized therapies. Here, we provide a short review of the current state-of-the-art of miRNAs in IBD pathogenesis, diagnostics and therapeutics. | Mehmet Coskun Jacob Tveiten Bjerrum Jakob Benedict Seidelin Ole Haagen Nielsen | 2012 | World Journal of Gastroenterology2012,18,34: | 18 |

| 12 | Manufacturing tolerant topology optimization显示文摘In this paper we present an extension of thetopology optimization method to include uncertainties dur-ing the fabrication of macro,micro and nano structures.Morespecifically,we consider devices that are manufactured usingprocesses which may result in(uniformly)too thin(eroded)or too thick(dilated)structures compared to the intendedtopology.Examples are MEMS devices manufactured usingetching processes,nano-devices manufactured using e-beamlithography or laser micro-machining and macro structuresmanufactured using milling processes.In the suggestedrobust topology optimization approach,under- andover-etching is modelled by image processing-based 'erode'and 'dilate' operators and the optimization problem is for-mulated as a worst case design problem.Applications ofthe method to the design of macro structures for minimumcompliance and micro compliant mechanisms show that themethod provides manufacturing tolerant designs with littledecrease in performance.As a positive side effect the robustdesign formulation also eliminates the longstanding prob-lem of one-node connected hinges in compliant mechanismdesign using topology optimization. | Ole Sigmund | 2009 | Acta Mechanica Sinica2009,25,2: | 12 |

| 14 | Impact of fine particles in ambient air on lung cancer显示文摘Recently,the International Agency for Research on Cancer(IARC)has classified outdoor air pollution and the particulate matter component of outdoor air pollution as class I carcinogen.Air pollution is consistently associated with lung cancer in epidemiologic and experimental studies.The IARC assessment is specifically designed as hazard identification,and it does not quantify the magnitude of the cancer risk.This article addresses the magnitude of the lung cancer risk in the population due to ambient air pollution exposure. | Gerard Hoek Ole Raaschou-Nielsen | 2014 | Chinese Journal of Cancer2014,33,4: | 10 |
| 15 | Exploiting Additive Manufacturing Infill in Topology Optimization for Improved Buckling Load显示文摘增材制造可实现优质多功能构件所具有的高度复杂几何构型的制备。可以直接制备内含多孔填充的结构部件是其独有特征的一个例证。现有的设计方法还难以充分利用这一设计自由度,直接获得类似结构的设计。本文将展示涂层方法 (coating approach)的拓扑优化方法来作为多孔填充构件的设计方法,所设计的构件具有显著改进的临界屈曲载荷,从而使得整体结构部件的稳定性增强。传统的柔顺性拓扑优化方法极少在数学模型中考虑构件的屈曲约束,稳定性要求通常要经过后续的校核与改进过程满足。这一后续过程往往只能获得次优设计。本文所展示的方法弥补了传统柔顺性拓扑优化模型中难以考虑构件屈曲约束的缺陷。利用涂层拓扑优化方法与传统柔顺性拓扑优化同时对经典的MBB梁进行设计,并采用熔丝增材制造技术对设计结果进行了制备。实验结果验证了涂层方法的数学模型的正确性。由于填充材料的性质,在相同条件下,涂层优化得到的多孔填充结构的屈曲载荷比传统优化得到的实体结构高四倍以上。 | Anders Clausen Niels Aage Ole Sigmund | 2016 | Engineering2016,2,2: | 9 |
| 16 | Modulation of Gut Microbiota in Pathological States显示文摘人类微生态是寄居在人体中的微生物聚集体,且主要存在于胃肠道(GIT)中。肠道微生态随着人体发育而演化,并在人类健康和疾病中起着重要作用。近年来,由于微生态会影响宿主代谢、生理学和免疫系统发育,而且微生态紊乱可能导致许多疾病,其越来越受到人们的关注。肠道微生态可能与恶性肿瘤有一定联系,如胃癌和结直肠癌;也可能与其他一些疾病有关,如非酒精性脂肪肝(NAFLD)、被称为工业化世界'生活方式疾病'的肥胖和糖尿病、冠心病以及中枢神经系统紊乱。虽然分子技术革命为我们更准确地研究肠道微生态提供了必要的工具,但是我们需要更精确地阐明其与某些人类疾病病理变化的关系,明确微生态在不同疾病中的作用是新的治疗策略发展的基础。本文概述了肠道微生态对人类健康的重要影响以及调整肠道菌群结构的潜在用途,如菌群移植用于治疗耐药艰难梭菌(C.difficile)的感染。通过微生态干预调整肠道区域以改善人类健康的概念虽刚刚兴起,但其治疗意义显著。因此,抑制有害菌、促进有益菌可能会保护人类健康,并且这些努力将为探索发展更加合理的治疗方案打下基础。 | Yulan Wang BaohongWang Junfang wu xiangyang Jiang Huiru Tang Ole H.

| 17 | Real-time high-resolution mid-infrared optical coherence tomography显示文摘The potential for improving the penetration depth of optical coherence tomography systems by using light sources with longer wavelengths has been known since the inception of the technique in the early 1990s.Nevertheless,the development of mid-infrared optical coherence tomography has long been challenged by the maturity and fidelity of optical components in this spectral region,resulting in slow acquisition,low sensitivity,and poor axial resolution.In this work,a mid-infrared spectral-domain optical coherence tomography system operating at a central wavelength of 4μm and an axial resolution of 8.6μm is demonstrated.The system produces two-dimensional cross-sectional images in real time enabled by a high-brightness 0.9-to 4.7-μm mid-infrared supercontinuum source with a pulse repetition rate of 1 MHz for illumination and broadband upconversion of more than 1-μm bandwidth from 3.58–4.63μm to 820–865 nm,where a standard 800-nm spectrometer can be used for fast detection.The images produced by the mid-infrared system are compared with those delivered by a state-of-the-art ultra-high-resolution near-infrared optical coherence tomography system operating at 1.3μm,and the potential applications and samples suited for this technology are discussed.In doing so,the first practical mid-infrared optical coherence tomography system is demonstrated,with immediate applications in real-time non-destructive testing for the inspection of defects and thickness measurements in samples that exhibit strong scattering at shorter wavelengths. | Niels M.Israelsen Christian R.Petersen Ajanta Barh Deepak Jain Mikkel Jensen Gunther Hannesschlager Peter Tidemand-Lichtenberg Christian Pedersen Adrian Podoleanu Ole Bang | 2019 | Light(Science & Applications)2019,8,1: | 7 |

| 20 | Impacts of livestock grazing on a savanna grassland in Kenya显示文摘The dynamics of most rangelands in Kenya remain to be poorly understood.This paper provides baseline information on the response of a semiarid rangeland under different livestock grazing regimes on land inhabited by the Massai people in the east side of Amboseli National Park in Kenya.The data were collected from grasslands designated into four types:(1) grassland from previous Massai settlements that had been abandoned for over twenty years;(2) grassland excluded from livestock grazing for eight years;(3) a dry season grazing area;and (4) a continuous grazing area where grazing occurred throughout all seasons.Collected data included grass species composition,grass height,inter-tuft distance,standing grass biomass and soil characteristics.The results indicated that continuous grazing area in semiarid rangelands exhibited loss of vegetation with negative,long-term effects on grass functional qualities and forage production,whereas grassland that used traditional Maasai grazing methods showed efficiency and desirable effects on the rangelands.The results also showed that abandoned homestead sites,though degraded,were important nutrient reservoirs. | John KIOKO John Warui KIRINGE Simon Ole SENO | 2012 | Journal of Arid Land2012,4,1: | 5 |
