| 1 | 埃达克岩:关于其成因的一些不同观点显示文摘埃达克岩的概念是十多年前提出来的,指由俯冲的年轻洋壳熔融形成的火成岩。自从最初在现代岛弧近十个地方报道埃达克岩以来,新近又在几个地方发现有埃达克岩(如日本西南部,外墨西哥火山岩带,等等)。但是,过去十多年的研究也表明,埃达克岩可以由俯冲期间的其它过程产生(例如,沿俯冲板片的撕裂边,留在上地幔中的板片残余等)。另外,埃达克岩似乎与一些岩石是共生组合,这些岩石包括高镁安山岩、富Nb的弧玄武岩(NEAB),还可能有玻安岩(几个研究者已在玻安岩中发现有埃达克岩的组分)。高镁安山岩不是来自埃达克与地幔的相互作用(Adak-type),就是来自此相互作用期间地幔的熔融(Piip-tyPe);富Nb的弧玄武岩,据认为是来自一种被埃达克岩广泛交代的地幔的部分熔融。作为一个新的岩套,埃达克岩交代火山岩系列已被建议用来解释各种岩石组合。此外,大量的富Nb弧玄武岩也已被发现包含有超镁铁质的地幔包体,而这些包体有高亏损地幔与埃达克岩反应的明显证据。 关于主要与下地壳熔融而不是与俯冲板片有关的埃达克岩的起源已提出几种假说。一个模型认为,下地壳熔融出现在玄武质岩浆底侵下地壳时。但是,有许多理由似乎可以排除这种模式。另一种模型认为,在大陆地壳很厚的区域,下地壳可能变成榴辉岩,从而拆离并下沉到地幔中(? | Marc J DEFANT 许继峰 Pavel KEPEZHINSKAS 王强 张旗 肖龙 | 2002 | 岩石学报2002,18,2: | 206 |
| 2 | Evolving management of colorectal cancer显示文摘This article reviews recent advances in surgical techniques and adjuvant therapies for colorectal cancer, including total mesorectal excision, the resection of liver and lung metastasis and advances in chemoradiation and foreshadows some interventions that may lie just beyond the frontier. In particular, little is known about the intracellular and extracellular cascades that may influence colorectal cancer cell adhesion and metastasis. Although the phosphorylation of focal adhesion kinases and focal adhesion associated proteins in response to integrin-mediated cell matrix binding ('outside in integrin signaling') is well described, the stimulation of cell adhesion by intracellular signals activated by pressure prior to adhesion represents a different signal paradigm. However, several studies have suggested that increased pressure and shear stress activate cancer cell adhesion. Further studies of the pathways that regulate integrin-driven cancer cell adhesion may identify ways to disrupt these signals or block integrin-mediated adhesion so that adhesion and eventual metastasis can be prevented in the future. | Jochem van der Voort van Zijp Harald J Hoekstra Marc D Basson | 2008 | World Journal of Gastroenterology2008,14,25: | 16 |
| 3 | The IKK-related kinases: from innate immunity to oncogenesis显示文摘在过去的四年,天生的有免疫力的反应的地被 kinase ( IKK )联系了 kinases ,坦克有约束力的 Kinase 1 ( TBK1 )和 IKKi 的 IB 的发现高度影响了,它调整干扰素的活动规章的因素( IRF ) -3/IRF-7 和 NF-B 抄写因素。更最近,激活这些 IKK 相当或相同事物的发信号的小径的另外的必要部件被发现了。这些包括 RNA helicases RIGi 和 MDA5,和作为 CARDIF/MAVS/VISA/IPS-1 知道的下游的 mitochondrial 受动器。除了他们在控制天生的有免疫力的反应的必要功能,最近的研究在房间增长和 oncogenesis 加亮这些 kinases 的一个角色。正规 IKK 很好被认出是连接长期的发炎到癌症的一座桥。新调查结果现在建议 IKK 相关的 kinases TBK1 和 IKKi 也参予影响房间转变和肿瘤前进的发信号的小径。这评论将因此由集中于他们的规定和底层特性在细胞的转变和 oncogenesis 总结并且讨论 TBK1 和 IKKi 的角色。 | Jean-Francois Clément | 2008 | Cell Research2008,18,9: | 16 |
| 4 | 定量药理学:一个促进药物开发及转换型研究严谨思考的多学科领域显示文摘尽管从事定量药理学研究的科学工作者一再强调将定量分析的原则应用于促进新药研发的决策,定量药理学的发展还是超过了上述领域。普通研究和决策领域总是期望着常规和传统的研究范例发生进步,当与定量药理学相关的领域自身在发展并与其交互作用时,自然便产生对临床药理学的协同作用。创新性和可塑性训练计划和策略均是将来临床研究工作中必不可少的要素。掌握定量药理学领域的知识成为对药理科学家的要求,具有定量药理学背景的人员可望获得更高的薪水。目前定量药理学相关培训计划,教学资料,及学术权威均比较贫乏,学生们可以从企业化、调控性的背景的教师等多种机构的教职员那获得指导,此外也可以通过在线课程,可视化教学进修课程,与他们的导师保持联系。对课程和学位的管理可以采取灵活的态度,这样可在短期内培养更多的定量药理学工作者。 | Jeffrey S Barrett Michael J Fossler K.David Cadieu Marc R Gastonguay 沈杰 谢海棠 孙瑞元 | 2008 | 中国临床药理学与治疗学2008,13,5: | 10 |

| 6 | Plasmonics for solid-state lighting: enhanced excitation and directional emission of highly efficient light sources显示文摘Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-statelighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability oflight emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, thefundamental research phase of SSL is coming to an end. In this study, we demonstrate a very large improvement in SSL emission (above70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonicstructures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminumnanoantennas. Our results open a new path for fundamental and applied research in SSL in which plasmonic nanostructures are able tomold the spectral and angular distribution of the emission with unprecedented precision. | Gabriel Lozano Davy J Louwers Said RK Rodrı´guez Shunsuke Murai Olaf TA Jansen Marc A Verschuuren Jaime Gomez Rivas | 2013 | Light(Science & Applications)2013,2,1: | 8 |
| 7 | Colon cancer and the epidermal growth factor receptor:Current treatment paradigms,the importance of diet,and the role of chemoprevention显示文摘Colorectal cancer represents the third most common and the second deadliest type of cancer for both men and women in the United States claiming over 50000 lives in 2014. The 5-year survival rate for patients diagnosed with metastatic colon and rectal cancer is < 15%. Early detection and more effective treatments are urgently needed to reduce morbidity and mortality of patients afflicted with this disease. Here we will review the risk factors and current treatment paradigms for colorectal cancer, with an emphasis on the role of chemoprevention as they relate to epidermal growth factor receptor(EGFR) blockade. We will discuss how various EGFR ligands are upregulated in the presence of Western diets high in saturated and N-6 polyunsaturated fats. We will also outline the various mechanisms of EGFR inhibition that are induced by naturally occurring chemopreventative agents such as ginseng, green tea, and curcumin. Finally, we will discuss the current role of targeted chemotherapy in colon cancer and outline the limitations of our current treatment options, describing mechanisms of resistance and escape. | Baldeep Pabla Marc Bissonnette Vani J Konda | 2015 | World Journal of Clinical Oncology2015,6,5: | 7 |
| 8 | High-resolution multimodal flexible coherent Raman endoscope显示文摘Coherent Raman scattering microscopy is a fast,label-free,and chemically specific imaging technique that shows high potential for future in vivo optical histology.However,the imaging depth in tissues is limited to the sub-millimeter range because of absorption and scattering.Realization of coherent Raman imaging using a fiber endoscope system is a crucial step towards imaging deep inside living tissues and providing information that is inaccessible with current microscopy tools.Until now,the development of coherent Raman endoscopy has been hampered by several issues,mainly related to the fiber delivery of the excitation pulses and signal collection.Here,we present a flexible,compact,coherent Raman,and multimodal nonlinear endoscope(4.2mm outer diameter,71mm rigid length)based on a resonantly scanned hollow-core Kagomé-lattice double-clad fiber.The fiber design enables distortion-less,background-free delivery of femtosecond excitation pulses and back-collection of nonlinear signals through the same fiber.Sub-micrometer spatial resolution over a large field of view is obtained by combination of a miniature objective lens with a silica microsphere lens inserted into the fiber core.We demonstrate high-resolution,high-contrast coherent anti-Stokes Raman scattering,and second harmonic generation endoscopic imaging of biological tissues over a field of view of 320μm at a rate of 0.8 frames per second.These results pave the way for intraoperative label-free imaging applied to real-time histopathology diagnosis and surgery guidance. | Alberto Lombardini Vasyl Mytskaniuk Siddharth Sivankutty Esben Ravn Andresen Xueqin Chen Jérôme Wenger Marc Fabert Nicolas Joly Frédéric Louradour Alexandre Kudlinski Hervé Rigneault | 2018 | Light(Science & Applications)2018,7,1: | 6 |
| 9 | Drug eluting biliary stents to decrease stent failure rates:Areview of the literature显示文摘Biliary stenting is clinically effective in relieving both malignant and non-malignant obstructions. However, there are high failure rates associated with tumor ingrowth and epithelial overgrowth as well as internally from biofilm development and subsequent clogging. Within the last decade, the use of prophylactic drug eluting stents as a means to reduce stent failure has been investigated. In this review we provide an overview of the current research on drug eluting biliary stents. While there is limited human trial data regarding the clinical benefit of drug eluting biliary stents in preventing stent obstruction, recent research suggests promise regarding their safety and potential efficacy. | Joseph Shatzel Jisoo Kim Kartik Sampath Sharjeel Syed Jennifer Saad Zilla H Hussain Kabir Mody J Marc Pipas Stuart Gordon Timothy Gardner Richard I Rothstein | 2016 | World Journal of Gastrointestinal Endoscopy2016,8,2: | 6 |

| 11 | Mobilization of hematopoietic progenitor cells in patients with liver cirrhosis显示文摘AIM:To test the hypothesis that liver cirrhosis is associated with mobilization of hematopoietic progenitor cells. METHODS:Peripheral blood samples from 72 patients with liver cirrhosis of varying etiology were analyzed by flow cytometry.Identified progenitor cell subsets were immunoselected and used for functional assays in vitro. Plasma levels of stromal cell-derived factor-1(SDF-1) were measured using an enzyme linked immunosorbent assay.RESULTS:Progenitor cells with a CD133 + /CD45 + CD14 + phenotype were observed in 61%of th patients.Between 1%and 26%of the peripheral bloo mononuclear cells(MNCs)displayed this phenotype Furthermore,a distinct population of c-kit + progenito cells(between 1%and 38%of the MNCs)could b detected in 91%of the patients.Additionally,18% of the patients showed a population of progenito cells(between 1%and 68%of the MNCs)that wa characterized by expression of breast cancer resistanc protein-1.Further phenotypic analysis disclosed tha the circulating precursors expressed CXC chemokin receptor 4,the receptor for SDF-1.In line with thi finding,elevated plasma levels of SDF-1 were presen in all patients and were found to correlate with th number of mobilized CD133 + progenitor cells. | Ursula M Gehling Marc Willems Kathleen Schlagner Ralf A Benndorf Maura Dandri Jrg Petersen Martina Sterneck Joerg-Matthias Pollok Dieter K Hossfeld Xavier Rogiers | 2010 | World Journal of Gastroenterology2010,16,2: | 4 |
| 12 | Acute effects of rotavirus and malnutrition on intestinal barrier function in neonatal piglets显示文摘AIM: To investigate the effect of protein-energy malnutrition on intestinal barrier function during rotavirus enteritis in a piglet model.METHODS: Newborn piglets were allotted at day 4 of age to the following treatments:(1) full-strength formula(FSF)/noninfected;(2) FSF/rotavirus infected;(3) half-strength formula(HSF)/noninfected;or(4) HSF/rotavirus infected.After one day of adjustment to the feeding rates,pigs were infected with rotavirus and acute effects on growth and diarrhea were monitored for 3 d and jejunal samples were collected for Ussingchamber analyses.RESULTS: Piglets that were malnourished or infected had lower body weights on days 2 and 3 post-infection(P < 0.05).Three days post-infection,marked diarrhea and weight loss were accompanied by sharp reductions in villus height(59%) and lactase activity(91%) and increased crypt depth(21%) in infected compared with non-infected pigs(P < 0.05).Malnutrition also increased crypt depth(21%) compared to full-fed piglets.Villus:crypt ratio was reduced(67%) with viral infection.There was a trend for reduction in transepithelial electrical resistance with rotavirus infection and malnutrition(P = 0.1).3H-mannitol flux was significantly increased(50%;P < 0.001) in rotavirus-infected piglets compared to non-infected piglets,but there was no effect of nutritional status.Furthermore,rotavirus infection reduced localization of the tight junction protein,occludin,in the cell membrane and increased localization in the cytosol.CONCLUSION: Overall,malnutrition had no additive effects to rotavirus infection on intestinal barrier function at day 3 post-infection in a neonatal piglet model. | Sheila K Jacobi Adam J Moeser Anthony T Blikslager J Marc Rhoads Benjamin A Corl Robert J Harrell Jack Odle | 2013 | World Journal of Gastroenterology2013,19,31: | 4 |

| 14 | Characterization of two rat models of cystic fibrosis—KO and F508del CFTR—Generated by Crispr-Cas9显示文摘Background: Genetically engineered animals are essential for gaining a proper understanding of the disease mechanisms of cystic fibrosis(CF). The rat is a relevant laboratory model for CF because of its zootechnical capacity, size, and airway characteristics, including the presence of submucosal glands.Methods: We describe the generation of a CF rat model(F508 del) homozygous for the p.Phe508 del mutation in the transmembrane conductance regulator(Cftr) gene. This model was compared to new Cftr-/-rats(CFTR KO). Target organs in CF were examined by histological staining of tissue sections and tooth enamel was quantified by micro-computed tomography. The activity of CFTR was evaluated by nasal potential difference(NPD) and short-circuit current measurements. The effect of VX-809 and VX-770 was analyzed on nasal epithelial primary cell cultures from F508 del rats.Results: Both newborn F508 del and Knock out(KO) animals developed intestinal obstruction that could be partly compensated by special diet combined with an osmotic laxative. The two rat models exhibited CF phenotypic anomalies such as vas deferens agenesis and tooth enamel defects. Histology of the intestine, pancreas, liver, and lungs was normal. Absence of CFTR function in KO rats was confirmed ex vivo by short-circuit current measurements on colon mucosae and in vivo by NPD, whereas residual CFTR activity was observed in F508 del rats. Exposure of F508 del CFTR nasal primary cultures to a combination of VX-809 and VX-770 improved CFTR-mediated Cl-transport.Conclusions: The F508 del rats reproduce the phenotypes observed in CFTR KO animals and represent a novel resource to advance the development of CF therapeutics. | Elise Dreano Marc Bacchetta Juliette Simonin Louise Galmiche Claire Usal Lotfi Slimani Jérémy Sadoine Laurent Tesson Ignacio Anegon Jean-Paul Concordet Aurélie Hatton Lucile Vignaud Danielle Tondelier Isabelle Sermet-Gaudelus Marc Chanson Charles-Henry Cottart | 2019 | Animal Models and Experimental Medicine2019,2,4: | 3 |

| 17 | Diagnostic value of drain amylase for detecting intrathoracic leakage after esophagectomy显示文摘AIM:To investigate the value of elevated drain amylase concentrations for detecting anastomotic leakage(AL) after minimally invasive Ivor-Lewis esophagectomy(MIILE).METHODS:This was a retrospective analysis of prospectively collected data in two hospitals in the Netherlands. Consecutive patients undergoing MI-ILE were included. A Jackson-Pratt drain next to the dorsal side of the anastomosis and bilateral chest drains were placed at the end of the thoracoscopic procedure. Amylase levels in drain fluid were determined in all patients during at least the first four postoperative days. Contrast computed tomography scans and/or endoscopic imaging were performed in cases of a clinically suspected AL. Anastomotic leakage was defined as any sign of leakage of the esophago-gastric anastomosis on endoscopy,re-operation,radiographic investigations,post mortal examination or when gastro-intestinal contents were found in drain fluid. Receiver operator characteristic curves were used to determine the cut-off values. Sensitivity,specificity,positive predictive value,negative predictive value,risk ratio and overall test accuracy were calculated for elevated drain amylase concentrations.RESULTS:A t o t a l o f 8 9 p a t ie n t s w e re in c lu d e d between March 2013 and August 2014. No differences in group characteristics were observed between patients with and without AL,except for age. Patients with AL were older than were patients without AL(P = 0.01). One patient(1.1%) without AL died within 30 d after surgery due to pneumonia and acute respiratory distress syndrome. Anastomotic leakage that required any intervention occurred in 15 patients(16.9%). Patients with proven anastomotic leakage had higher drain amylase levels than patients without anastomotic leakage [median 384 IU/L(IQR 34-6263) vs median 37 IU/L(IQR 26-66),P = 0.003]. Optimal cut-off values on postoperative days 1,2,and 3 were 350 IU/L,200 IU/L and 160 IU/L,respectively. An elevated amylase level was found in 9 of the 15 patients with AL. Five of these 9 patients had early elevations of their amylase levels,with a median of 2 d(IQR 2-5) before signs and symptoms occurred.CONCLUSION:Measurement of drain amylase levels is an inexpensive and easy tool that may be used to screen for anastomotic leakage soon after MI-ILE. However,clinical validation of this marker is necessary. | Gijs HK Berkelmans Ewout A Kouwenhoven Boudewijn JJ Smeets Teus J Weijs Luis C Silva Corten Marc J van Det Grard AP Nieuwenhuijzen Misha DP Luyer | 2015 | World Journal of Gastroenterology2015,21,30: | 3 |

| 19 | Bovine immunoglobulin protein isolates for the nutritional management of enteropathy显示文摘The gastrointestinal tract is responsible for a multitude of digestive and immune functions which depend upon the balanced interaction of the intestinal microbiota, diet, gut barrier function, and mucosal immune response. Disruptions in one or more of these factors can lead to intestinal disorders or enteropathies which are characterized by intestinal inflammation, increased gut permeability, and reduced capacity to absorb nutrients. Enteropathy is frequently associated with human immunodeficiency virus(HIV) infection, inflammatory bowel disease, autoimmune enteropathy, radiation enteritis, and irritable bowel syndrome(IBS), where pathologic changes in the intestinal tract lead to abdominal discomfort, bloating, abnormal bowel function(e.g., diarrhea, urgency, constipation and malabsorption). Unfortunately, effective therapies for the management ofenteropathy and restoring intestinal health are still not available. An accumulating body of preclinical studies has demonstrated that oral administration of plasmaor serum-derived protein concentrates containing high levels of immunoglobulins can improve weight, normalize gut barrier function, and reduce the severity of enteropathy in animal models. Recent studies in humans, using serum-derived bovine immunoglobulin/protein isolate, demonstrate that such protein preparations are safe and improve symptoms, nutritional status, and various biomarkers associated with enteropathy. Benefits have been shown in patients with HIV infection or diarrhea-predominant IBS. This review summarizes preclinical and clinical studies with plasma/serum protein concentrates and describes the effects on host nutrition, intestinal function, and markers of intestinal inflammation. It supports the concept that immunoglobulin-containing protein preparations may offer a new strategy for restoring functional homeostasis in the intestinal tract of patients with enteropathy. | Bryon W Petschow Anthony T Blikslager Eric M Weaver Joy M Campbell Javier Polo Audrey L Shaw Bruce P Burnett Gerald L Klein J Marc Rhoads | 2014 | World Journal of Gastroenterology2014,20,33: | 2 |
