7Tomographic PIV investigation of coherent structures in a turbulent boundary layer flow显示文摘Tomographic particle image velocimetry was used to quantitatively visualize the three-dimensional coherent structures in the logarithmic region of the turbulent boundary layer in a water tunnel.The Reynolds number based on momentum thickness is Reθ = 2 460.The instantaneous velocity fields give evidence of hairpin vortices aligned in the streamwise direction forming very long zones of low speed fluid,which is flanked on either side by highspeed ones.Statistical support for the existence of hairpins is given by conditional averaged eddy within an increasing spanwise width as the distance from the wall increases,and the main vortex characteristic in different wall-normal regions can be reflected by comparing the proportion of ejection and its contribution to Reynolds stress with that of sweep event.The pre-multiplied power spectra and two-point correlations indicate the presence of large-scale motions in the boundary layer,which are consistent with what have been termed very large scale motions(VLSMs).The three dimen-sional spatial correlations of three components of velocity further indicate that the elongated low-speed and highspeed regions will be accompanied by a counter-rotating roll modes,as the statistical imprint of hairpin packet structures,all of which together make up the characteristic of coherent structures in the logarithmic region of the turbulent boundary layer(TBL).Zhan-Qi Tang Nan Jiang Andreas Schroder Reinhard Geisler 2012Acta Mechanica Sinica2012,28,3:14
8七个发达国家卫生系统的领导与治理显示文摘本文运用结构式调查方法,探讨了澳大利亚、英国、德国、荷兰、挪威、瑞典和瑞士七个发达国家卫生系统的领导和治理情况。领导与治理模式包含三项基本职能:优先顺序设置、绩效监管和问责制。各国卫生系统的领导和治理方法存在着显著差异,零散并略显随意。虽然各国在卫生系统的总体目标上达成了共识,但设置优先顺序的途径各不相同。成本效益分析作为设置卫生系统运行优先顺序的一个主要方法被各国加以广泛运用,但并未发挥核心作用。各国虽然处于不同的发展阶段,但绩效监管却能广泛吸收有益意见。问责制特别是在最优方法的不确定性方面,各国之间的差异最大。大多数情况下,市场机制、选举程序、直接经济激励以及专业监督与控制等几种不同问责机制的组合可能更为合适。而且这些机制应与优先顺序设置和绩效监管协调一致。Peter C Smith Anders Anell Reinhard Busse Luca Crivelli Judith Healy Anne Karin Lindahl Gert Westert Tobechukwu Kene 2012中国卫生政策研究2012,5,11:13
9流动注射-荧光法同时测定水中的镍和锌显示文摘研究了用流动注射荧光法测定水中的镍和锌。镍和锌都使新点绿NG(NewportGreenTM)的荧光加强,分别测定时均有良好的线性关系,线性范围为10μg/L~200μg/L,检测限分别为8.1μg/L和8.4μg/L;镍与NewportGreenTM反应缓慢,而锌与NewportGreenTM是瞬间反应,因此,记录某一时间点的荧光强度,利用荧光强度的加和性原理,研究了同时测定水体中的镍和锌方法。张敬东 Reinhard Niessner 2002分析试验室2002,21,4:12

14Genomic alterations and molecular subtypes of gastric cancers in Asians显示文摘Gastric cancer(GC) is a highly heterogenic disease,and it is the second leading cause of cancer death in the world.Common chemotherapies are not very effective for GC,which often presents as an advanced or metastatic disease at diagnosis.Treatment options are limited,and the prognosis for advanced GCs is poor.The landscape of genomic alterations in GCs has recently been characterized by several international cancer genome programs,including studies that focused exclusively on GCs in Asians.These studies identified major recurrent driver mutations and provided new insights into the mutational heterogeneity and genetic profiles of GCs.An analysis of gene expression data by the Asian Cancer Research Group(ACRG) further uncovered four distinct molecular subtypes with well-defined clinical features and their intersections with actionable genetic alterations to which targeted therapeutic agents are either already available or under clinical development.In this article,we review the ACRG GC project.We also discuss the implications of the genetic and molecular findings from various GC genomic studies with respect to developing more precise diagnoses and treatment approaches for GCs.Xiang S.Ye Chunping Yu Amit Aggarwal Christoph Reinhard 2016Chinese Journal of Cancer2016,35,8:10

16A high frequency of GBV-C/HGV coinfection in hepatitis C patients in Germany显示文摘AIM To detect infection rate of GBV-C/HGV inhepatitis C patients,to determine the methodsof higher sensitivity and the primers of higherefficiency for GBV-C/HGV RNA detection and tostudy the dominant subtype and mutation ofGBV-C/HGV.METHODS Quantitative RT-PCR for detectionpf HCV RNA concentration in serum samples,RT-nested PCR with two sets of primers fordetection of GBV-C RNA,RT-PCR ELISA with twosets of primers for detection of HGV RNA,nucleotide sequence and putative amino acidsequence analysis.RESULTS The positive rates of GBV-C RNA atthe 5’-NCR and NS3 region in 211 serums amplesfrom the patients with HCV infection were 31.8%and 22.8% respectively.The positive rates ofHGV RNA at the 5’-NCR and NS5 region in thesame samples were 47.9% and 31.8%respectively.The total positive rate of GBV-C/HGV RNA was as high as 55.5%.HCV copynumbers in the patients without GBV-C/ HGVcoinfection were statistically higher than that inthe patients with GBV-C/ HGV coinfection(P<0.01).Frequent mutation of nucleotideresidue was present in the amplificationproducts.Frameshift mutation was found in twosamples with GBV-C NS3 region nucleotidesequences.All nucleotide sequences fromamplification products showed higher homologyto HGV genome than to GBV-C genome even though part of the sequences were amplifiedwith GBV-C primers.CONCLUSION A high frequency of GBV-C/ HGV coinfection existed in the hepatitis C patients. RT-PCR ELISA was more sensitive than RT-nested PCR for detection of GBV-C/ HGV RNA. The primers derived from the 5 -NCR was more efficient than those derived from the NS3 and NS5 regions. A reverse relationship was found to exist between HCV RNA concentration and GBV-C/ HGV infection frequency. HGV was the dominant subtype of the virus in the local area. The major mutations of GBV-C/ HGV genomes were random mutation of nucleotide residue.Reinhard H. Dennin 2000World Journal of Gastroenterology2000,6,6:9
17Experimental small bowel preservation using Polysol: A new alternative to University of Wisconsin solution, Celsior and histidine-tryptophan-ketoglutarate solution?显示文摘AIM: To evaluate the potential of Polysol, a newly developed preservation solution, in cold storage of small bowel grafts, compared with the current standards, University of Wisconsin solution (UW), Celsior and histidine-tryptophan-ketoglutarate solution (HTK). METHODS: Male Wistar rats were used as donors. Small bowels were retrieved, flushed and then stored in the respective 4 solutions for 18 h at 4℃. Functional integrity of the grafts was evaluated by isolated reperfusion with oxygenated Krebs-Henseleit buffer at 37℃ for 30 min in all 4 groups. RESULTS: Polysol preservation exhibited the highest tissue ATP concentration and the lowest release of LDH. Malondialdehyde, an index for tissue lipid peroxidation, was also the lowest in Polysol. Tissue oxygen consumption was significantly higher in Polysol than in the others. Of interest, UW-storage promoted 10-fold higher apoptosis than in the others. Moreover, electron microscopy revealed that the mucosal villi/micro-villi formation and the cell organelles, including mitochondria, were both significantly better preserved in Polysol, while deleterious alterations were apparent in the others, most notably in UW. Although Celsior and HTK exhibited the better trend of results than UW in some parameters, but could not reach the over-all superiority to UW.CONCLUSION: Cold storage using Polysol resulted in significantly better integrity and function of small bowel grafts than UW. Hence, Polysol may be a novel alternative for the small bowel preservation.Lai Wei Koichiro Hata Benedict Marie Doorschodt Reinhard Büttner Thomas Minor René H Tolba 2007World Journal of Gastroenterology2007,13,27:9

20Dental and periodontal phenotype in sclerostin knockout mice显示文摘Sclerostin is a Wnt signalling antagonist that controls bone metabolism.Sclerostin is expressed by osteocytes and cementocytes;however,its role in the formation of dental structures remains unclear.Here,we analysed the mandibles of sclerostin knockout mice to determine the influence of sclerostin on dental structures and dimensions using histomorphometry and micro-computed tomography(mCT)imaging.mCT and histomorphometric analyses were performed on the first lower molar and its surrounding structures in mice lacking a functional sclerostin gene and in wild-type controls.mCT on six animals in each group revealed that the dimension of the basal bone as well as the coronal and apical part of alveolar part increased in the sclerostin knockout mice.No significant differences were observed for the tooth and pulp chamber volume.Descriptive histomorphometric analyses of four wild-type and three sclerostin knockout mice demonstrated an increased width of the cementum and a concomitant moderate decrease in the periodontal space width.Taken together,these results suggest that the lack of sclerostin mainly alters the bone and cementum phenotypes rather than producing abnormalities in tooth structures such as dentin.Ulrike Kuchler Uwe Y Schwarze Toni Dobsak Patrick Heimel Dieter D Bosshardt Michaela Kneissel Reinhard Gruber 2014International Journal of Oral Science2014,6,2:7
