2可视耳模拟器在颞骨解剖虚拟训练中的应用显示文摘众所周知,颞骨空间构造复杂,其内部精细结构与面神经、中后颅底以及颈内动静脉等有着十分密切的关系。为了安全有效地施行手术和不断提高手术技能,耳外科医生必须熟知正常颞骨内部的解剖结构及其相互关系,并且要在真实的解剖环境中进行手术操作模拟练习。人类颞骨标本无疑是解剖手术训练最好的模型,但由于各种原因,目前在全世界范围内可用于该目的的人类颞骨资源十分有限,黄孝文 余洋 周良强 Sorensen MS Mosegaard J Noe K Mikkelsen PT 2013听力学及言语疾病杂志2013,21,4:7
3Subcurative 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
4“Dietary fibre”: moving beyond the “soluble/insoluble” classification for monogastric nutrition, with an emphasis on humans and pigs显示文摘This review describes dietary fibres originating from a range of foods,particularly in relation to their plant cell walls.It explores the categorization of dietary fibres into 'soluble' or 'insoluble'.It also emphasizes dietary fibre fermentability,in terms of describing how the gastro-intestinal tract(GIT) microbiota respond to a selection of fibres from these categories.Food is categorized into cereals,legumes,fruits and vegetables.Mention is also made of example whole foods and why differences in physico-chemical characteristics between 'purified' and 'non-purified'food components are important in terms of health.Lastly,recommendations are made as to how dietary fibre could be classified differently,in relation to its functionality in terms of fermentability,rather than only its solubility.Barbara A.Williams Deirdre Mikkelsen Bernadine M.Flanagan Michael J.Gidley 2019Journal of Animal Science and Biotechnology2019,10,3:5

8Sap flow for beech(Fagus sylvatica L.)in a natural and a managed forest—effect of spatial heterogeneity显示文摘Aims Beech(Fagus sylvatica L.)is an important species in natural and managed forests in Europe.This drought-sensitive species dominates even-aged stands as well more natural stands composed of a mixture of tree species,age and size classes.This study evaluates the extent that heterogeneity in spacing and tree diameter affect the seasonal availability and use of water.Methods Two stands were evaluated:(i)a heterogeneous forest remnant(NAT)with trees up to;300 years old,a mean top height of 28.4 m and a total of 733 stems ha1with stem diameters averaging 18 cm and(ii)an even-aged 80-year old stand(MAN),with a height of 25 m,and a total of 283 stems ha1 with diameters averaging 38 cm.Stem sap flow,Js(g m2 s1),was continuously measured in 12(MAN)and 13(NAT)trees using 20-mm long heat dissipation sensors.Individual tree measures of sap flow were correlated using non-linear statistical methods with air vapour pressure deficit(D,hPa)and global radiation(Rg,J m2 day1),along with constraints imposed by reductions in soil water content(SWC).SWC was measured as volumetric%using time domain reflectometry.Important Findings The daily integrated Js(Js-sum)for trees growing in the evenly spaced MAN stand and trees in canopy and closed forest positions in NAT stand decreased as the availability of soil moisture was reduced.In the heterogeneous NAT stand,SWC in a recently formed canopy gap remained high throughout the vegetation period.Based on regression models,the predicted relative decrease in Js-sum for dry relative to moist soil water conditions in the closed forest(at mean daily D=10 hPa)was 7–11%for trees near the gap and 39–42%for trees in the closed forest.In MAN,the reduction in Js-sum was 29%in dry relative to moist conditions.Js-sum in the outer 20 mm of the xylem in NAT was lower than that in MAN and the rate of decline in Js with xylem depth was less in NAT than in MAN.In MAN,Js-sum in deep and outer xylem was negatively affected at low soil moisture availability;in NAT,this was the case for only the outer xylem indicating that deep roots could be important in supplying water at times of low soil moisture in the upper soil.Lise Dalsgaard Teis Nørgaard Mikkelsen Annemarie Bastrup-Birk 2011Journal of Plant Ecology2011,4,1:2

10Shadow Education in Denmark:In the Light of the Danish History of Pedagogy and the Skepticism Toward Competition显示文摘Purpose:This article investigates the role of private supplementary tutoring in Denmark in light of the country’s pedagogical traditions in schools and leisure spheres.Design/Approach/Methods:Although tutoring activities are increasing,the phenomenon is not as prevalent in Denmark as in many other countries.In this article,we look into the history of Danish pedagogy for answers as to why this is the case.In the analytical sections of the article,we include research on parental values of child-rearing,as well as findings from a pilot study on Danish families purchasing private supplementary tutoring,the public debate about private tutoring,and contemporary youth research.Findings:With a solid emphasis on democracy and equality in Danish pedagogy,the conditions for increasing private supplementary tutoring in Denmark have been challenged.However,a current focus on global competition,formal competencies,and higher academic performance among children and young people suggests that providers of private tutoring perhaps face a brighter future—also in Denmark.Originality/Value:This article addresses a new field of qualitative research on private supplementary tutoring in Denmark and may be a platform for further reflection and empirical research.Sidse Hφlvig Mikkelsen David Thore Gravesen 2021ECNU Review of Education2021,4,3:2
