4Tight junctions in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer显示文摘Inflammatory bowel diseases are characterised by inflammation that compromises the integrity of the epithelial barrier. The intestinal epithelium is not only a static barrier but has evolved complex mechanisms to control and regulate bacterial interactions with the mucosal surface. Apical tight junction proteins are critical in the maintenance of epithelial barrier function and control of paracellular permeability. The characterisation of alterations in tight junction proteins as key players in epithelial barrier function in inflammatory bowel diseases is rapidly enhancing our understanding of critical mechanisms in disease pathogenesis as well as novel therapeutic opportunities. Here we give an overview of recent literature focusing on the role of tight junction proteins, in particular claudins, in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer.Jonathan Landy Emma Ronde Nick English Sue K Clark Ailsa L Hart Stella C Knight Paul J Ciclitira Hafid Omar Al-Hassi 2016World Journal of Gastroenterology2016,22,11:39
5时间分辨红外光谱对丝蛋白膜构象转变动力学的研究──再生蚕丝蛋白膜在高浓度醇溶液中的构象转变显示文摘运用时间分辨红外光谱研究再生蚕丝蛋白膜在高浓度醇溶液中 (醇含量≥ 90 % )的构象转变过程 .研究结果表明 ,丝蛋白膜在纯甲醇中可以发生构象转变 ,但是在纯乙醇和纯异丙醇中却几乎不能发生构象转变 .进一步研究发现 ,当乙醇和异丙醇溶液中的水含量达到 7%~ 8%时 ,丝蛋白开始发生构象转变 .在研究的醇溶液浓度范围中 ,丝蛋白发生构象转变的速率随醇溶液中水含量的增加而增大 .根据实验结果 ,认为丝蛋白膜在溶液体系中 (无论是有机溶剂溶液还是离子溶液 )发生构象转变 ,膜的溶胀是一个前提因素 ,其原因在于溶胀可使分子链获得运动的空间 ,从而通过氢键重组而发生构象转变 .陈新 周丽 邵正中 周平 KNIGHT David P VOLLRATH Fritz 2003化学学报2003,61,4:22
6时间分辨红外光谱对丝蛋白膜构象转变动力学的研究:不同碱金属离子对蜘蛛丝蛋白膜构象转变的影响显示文摘运用时间分辨红外光谱对碱金属盐溶液诱导发生的蜘蛛丝蛋白膜的构象转变过程进行跟踪研究.结果表明虽然构象转变速率为NaCl>KCl>LiCl,但是在最终完成构象转变的丝蛋白膜中 β 折叠结构的比例却是KCl>LiCl>NaCl.综合膜的构象转变速率和程度,可以认为在三种碱金属盐中,KCl最有利于丝蛋白的构象转变,这与钾在蜘蛛吐丝过程中起重要作用的观点(即发现在丝腺体中的丝蛋白胶状物,越靠近吐丝口,钾离子含量越高)相吻合.同时根据对构象转变动力学数据的分析,认为蜘蛛丝蛋白膜的构象转变由快慢两相组成,其中较快相(相应时间常数为5min左右)对应于链段运动引起的构象转变,而较慢相(相应时间常数为 5 0min左右)陈新 邵正中 KNIGHT David P.

8Lateral distributions of streamwise velocity in compound channels with partially vegetated floodplains显示文摘Natural rivers are commonly characterized by a main channel for primary flow conveyance and a floodplain, often partially covered with vegetation such as shrubs or trees, to carry extra flow during floods. The hydraulic resistance due to vegetation on the floodplain typically causes a further reduction of flow velocity and increases the velocity difference between the main channel and the floodplain. As a consequence a strong lateral shear layer leads to the exchange of mass and momentum between the main channel and floodplain, which in turn affects the overall channel conveyance and certain fluvial processes. The prediction of the lateral velocity distribution is important for many flood alleviation schemes, as well as for studies on sediment transport and dispersion in such channels. The present paper proposes a method for predicting the depth-averaged velocity in compound channels with partially vegetated floodplains, based on an analytical solution to the depth-integrated Reynolds-Averaged Navier-Stokes equation with a term included to account for the effects of vegetation. The vegetation is modelled via an additional term in the momentum equation to account for the additional drag force. The method includes the effects of bed friction, drag force, lateral turbulence and secondary flows, via four coefficients f, CD, λ & Γ respectively. The predicted lateral distributions of depth-averaged velocity agree well with the experimental data. The analytical solutions can also be used to predict the distribution of boundary shear stresses, which adds additional weight to the method proposed.KNIGHT Donald W 2009Science China(Technological Sciences)2009,52,11:13
9Canadian Agility and Movement Skill Assessment(CAMSA):Validity, objectivity, and reliability evidence for children 8–12 years of age显示文摘Purpose: The primary aim of this study was to develop an assessment of the fundamental, combined, and complex movement skills required to support childhood physical literacy. The secondary aim was to establish the feasibility, objectivity, and reliability evidence for the assessment.Methods: An expert advisory group recommended a course format for the assessment that would require children to complete a series of dynamic movement skills. Criterion-referenced skill performance and completion time were the recommended forms of evaluation. Children, 8–12 years of age, self-reported their age and gender and then completed the study assessments while attending local schools or day camps. Face validity was previously established through a Delphi expert(n = 19, 21% female) review process. Convergent validity was evaluated by age and gender associations with assessment performance. Inter-and intra-rater(n = 53, 34% female) objectivity and test–retest(n = 60, 47% female) reliability were assessed through repeated test administration.Results: Median total score was 21 of 28 points(range 5–28). Median completion time was 17 s. Total scores were feasible for all 995 children who self-reported age and gender. Total score did not differ between inside and outside environments(95% confidence interval(CI) of difference:-0.7 to 0.6;p = 0.91) or with/without footwear(95%CI of difference:-2.5 to 1.9; p = 0.77). Older age(p < 0.001, η2= 0.15) and male gender(p < 0.001, η2= 0.02)were associated with a higher total score. Inter-rater objectivity evidence was excellent(intraclass correlation coefficient(ICC) = 0.99) for completion time and substantial for skill score(ICC = 0.69) for 104 attempts by 53 children(34% female). Intra-rater objectivity was moderate(ICC = 0.52) for skill score and excellent for completion time(ICC = 0.99). Reliability was excellent for completion time over a short(2–4 days; ICC = 0.84) or long(8–14days; ICC = 0.82) interval. Skill score reliability was moderate(ICC = 0.46) over a short interval, and substantial(ICC = 0.74) over a long interval.Conclusion: The Canadian Agility and Movement Skill Assessment is a feasible measure of selected fundamental, complex and combined movement skills, which are an important building block for childhood physical literacy. Moderate-to-excellent objectivity was demonstrated for children 8–12 years of age. Test–retest reliability has been established over an interval of at least 1 week. The time and skill scores can be accurately estimated by 1 trained examiner.Patricia E.Longmuir Charles Boyer Meghann Lloyd Michael M.Borghese Emily Knight Travis J.Saunders Elena Boiarskaia Weimo Zhu Mark S.Tremblay 2017Journal of Sport and Health Science2017,6,2:10
10Emerging Trends for Microbiome Analysis: From Single-Cell Functional Imaging to Microbiome Big Data显示文摘Method development has always been and will continue to be a core driving force of microbiome science.In this perspective, we argue that in the next decade, method development in microbiome analysis will be driven by three key changes in both ways of thinking and technological platforms:(1) a shift from dissecting microbiota structure by sequencing to tracking microbiota state, function, and intercellular interaction via imaging;(2) a shift from interrogating a consortium or population of cells to probing individual cells;and(3) a shift from microbiome data analysis to microbiome data science. Some of the recent methoddevelopment efforts by Chinese microbiome scientists and their international collaborators that underlie these technological trends are highlighted here. It is our belief that the China Microbiome Initiative has the opportunity to deliver outstanding 'Made-in-China' tools to the international research community, by building an ambitious, competitive, and collaborative program at the forefront of method development for microbiome science.Jian xu Bo Ma Xiaoquan Su Shi Huang Xin Xu Xuedong Zhou Wei Huang Rob Knight 2017Engineering2017,3,1:9
11神农架国家公园居民可持续旅游感知空间分异及影响机理研究显示文摘在我国生态文明建设的背景下,国家公园已成为我国自然保护地管理体系改革的重中之重。居民作为国家公园的核心利益相关者,是自然生态系统保护的主体,也是可持续旅游发展的关键。通过引入可持续旅游棱镜模型,构建居民可持续感知与支持度的结构关系模型。以神农架国家公园3个典型社区(木鱼、红坪、下谷坪土家族乡)为研究对象,对不同空间区位社区居民的可持续感知差异及影响机理进行探讨。研究发现:(1)相较于旅游经济影响感知在过渡及边缘社区发挥主导作用,政策制度影响感知在核心社区成为影响居民满意度的关键因素;(2)国家公园建设对居民的生活质量和环境认知产生显著影响,并表现出明显的地域分异;(3)旅游发展满意度对支持度有显著正向影响,且满意度的中介效用随距离增加而衰减;(4)国家公园社区居民可持续评价的空间分异呈现出独特规律。即核心区和边缘区的经济和社会文化影响感知均高于过渡区;而环境和制度影响感知则由核心区向边缘区递增。为此,在神农架国家公园建设过程中,应全面衡量旅游发展效果,注重居民核心诉求,健全社区参与机制。要完善利益分配制度,将发展成果惠及所有居民。同时通过差异化社区发展路径,提高所有居民对旅游发展的认可和支持。龚箭 刘畅 David Knight 2021长江流域资源与环境2021,30,12:7

14Do neutrophil extracellular traps contribute to the heightened risk of thrombosis in inflammatory diseases?显示文摘Thrombotic events,both arterial and venous,are a major health concern worldwide. Further,autoimmune diseases,such as systemic lupus erythematosus,anti-neutrophil cytoplasmic antibody(ANCA)-associated vasculitis,and antiphospholipid syndrome,predispose to thrombosis,and thereby push the risk for these morbid events even higher. In recent years,neutrophils have been identified as important players in both arterial and venous thrombosis. Specifically,chromatin-based structures called neutrophil extracellular traps(NETs) play a key role in activating the coagulation cascade,recruiting platelets,and serving as scaffolding upon which the thrombus can be assembled. At the same time,neutrophils and NETs are emerging as important mediators of pathogenic inflammation in the aforementioned autoimmune diseases. Here,we first review the general role of NETs in thrombosis. We then posit that exaggerated NET release contributes to the prothrombotic diatheses of systemic lupus erythematosus,ANCA-associated vasculitis,and antiphospholipid syndrome.Ashish N Rao Nayef M Kazzaz Jason S Knight 2015World Journal of Cardiology2015,7,12:6
15Subcurative radiation significantly increases cell proliferation, invasion, and migration of primary glioblastoma multiforme in vivo显示文摘Tumor cell proliferation, infiltration, migration, and neovascularization are known causes of treatment resistance in glioblastoma multiforme(GBM). The purpose of this study was to determine the effect of radiation on the growth characteristics of primary human GBM developed in a nude rat. Primary GBM cells grown from explanted GBM tissues were implanted orthotopically in nude rats. Tumor growth was confirmed by magnetic resonance imaging on day 77(baseline) after implantation. The rats underwent irradiation to a dose of 50 Gy delivered subcuratively on day 84 postimplantation(n = 8), or underwent no radiation(n = 8). Brain tissues were obtained on day 112(nonirradiated) or day 133(irradiated). Immunohistochemistry was performed to determine tumor cell proliferation(Ki-67) and to assess the expression of infiltration marker(matrix metalloproteinase-2, MMP-2) and cell migration marker(CD44). Tumor neovascularization was assessed by microvessel density using von-Willebrand factor(vWF) staining. Magnetic resonance imaging showed well-developed, infiltrative tumors in 11 weeks postimplantation. The proportion of Ki-67-positive cells in tumors undergoing radiation was(71 ± 15)% compared with(25 ± 12)% in the nonirradiated group(P = 0.02). The number of MMP-2-positive areas and proportion of CD44-positive cells were also high in tumors receiving radiation, indicating great invasion and infiltration. Microvessel density analysis did not show a significant difference between nonirradiated and irradiated tumors. Taken together, we found that subcurative radiation significantly increased proliferation, invasion, and migration of primary GBM. Our study provides insights into possible mechanisms of treatment resistance following radiation therapy for GBM.Adarsh Shankar Sanath Kumar Asm Iskander Nadimpalli RS Varma Branislava Janic Ana deCarvalho Tom Mikkelsen Joseph A Frank Meser M Ali Robert A Knight Stephen Brown Ali S Arbab 2014Chinese Journal of Cancer2014,33,3:5
1620世纪90年代中国国有企业改革对城镇劳动力市场的影响显示文摘本文试图用2000年中国6省13市5300个家庭的入户调查数据来分析和总结上世纪90年代中后期,中国国有企业大幅裁员政策对城镇劳动力市场的影响。在考察未下岗城镇职工、下岗城镇职工和进城农民工等三个群体的工资形成过程之后,我们用Probit模型和半参数模型分别考察了下岗的决定因素以及城镇职工失业持续时间的决定因素。我们发现:城镇劳动力市场对进城农民工的传统歧视和偏见已经大为减少,但是城镇下岗职工却不得不参与日趋激烈的劳动力市场竞争。到数据调查结束时,绝大部分下岗职工依然处于失业状态;少数已经再就业的职工工资也很低,他们的生产特征没有得到相应的回报。至少就短期而言,下岗职工还得受到市场信息不对称和有限就业机会的制约。夏庆杰 宋丽娜 John Knight Simon Appleton 2009世界经济2009,32,4:5
17R-spondin-2 is a Wnt agonist that regulates osteoblast activity and bone mass显示文摘The R-spondin family of proteins are Wnt agonists, and the complete embryonic disruption of Rspo2 results in skeletal developmental defects that recapitulate the phenotype observed with Lrp5/6 deficiency. Previous work has shown that R-spondin-2(Rspo2, RSPO2) is both highly expressed in Wnt-stimulated pre-osteoblasts and its overexpression induces osteoblast differentiation in the same cells, supporting its putative role as a positive autocrine regulator of osteoblastogenesis. However, the role of Rspo2 in regulating osteoblastogenesis and bone formation in postnatal bone has not been explored. Here we show that limb-bud progenitor cells from Rspo2 knockout mice undergo reduced mineralization during osteoblastogenesis in vitro and have a corresponding alteration in their osteogenic gene expression profile. We also generated the first Rspo2 conditional knockout(Rspo2 floxed) mouse and disrupted Rspo2 expression in osteoblast-lineage cells by crossing to the Osteocalcin-Cre mouse line(OcnCre + Rspo2 ^(f/f)). Ocn-Cre + Rspo2 f/fmale and female mice at 1, 3, and 6 months were examined. Ocn-Cre + Rspo2 f/fmice are decreased in overall body size compared to their control littermates and have decreased bone mass. Histomorphometric analysis of1-month-old mice revealed a similar number of osteoblasts and mineralizing surface per bone surface with a simultaneous decrease in mineral apposition and bone formation rates. Consistent with this observation, serum osteocalcin in 3-month-old Ocn-Cre +Rspo2 f/fwas reduced, and bone marrow-mesenchymal stem cells from Ocn-Cre + Rspo2 f/fmice undergo less mineralization in vitro.Finally, gene expression analysis and immunohistochemistry of mature bone shows reduced beta-catenin signaling in Ocn-Cre +Rspo2 f/f. Overall, RSPO2 reduces osteoblastogenesis and mineralization, leading to reduced bone mass.M.Noelle Knight Kannan Karuppaiah Michele Lowe Sarthak Mohanty Robert L.Zondervan Sheila Bell Jaimo Ahn Kurt D.Hankenson 2018Bone Research2018,6,3:5
18A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5
19A comprehensive investigation of loading variance influence on fuel consumption and gas emissions in mine haulage operation显示文摘The data collected from haul truck payload management systems at various surface mines show that the payload variance is significant and must be considered in analysing the mine productivity, diesel energy consumption, greenhouse gas emissions and associated costs. The aim of this study is to determine the energy and cost saving opportunities for truck haulage operations associated with the payload variance in surface mines. The results indicate that there is a non-linear relationship between the payload variance and the fuel consumption, greenhouse gas emissions and associated costs. A correlation model, which is independent of haul road conditions, has been developed between the payload variance and the cost saving using the data from an Australian surface coal mine. The results of analysis for this particular mine show that a significant saving of fuel and greenhouse gas emissions costs is possible if the standard deviation of payload is reduced from the maximum to minimum value.Soofastaei A.
