| 1 | Echoplanar diffusion - weighted MRI with intravenous gadolinium - DTPA显示文摘It is occasionally necessary to repeat diffusion weighted imaging(DWI)after giving intravenous contrast medium(CM).However,the effects of CM on DWI and apparent diffusion coefficients(ADC)have not been fully ex-amined.The aim of this prospective study was to investigate whether there are any diagnostically significant dif-ferences between echo-planar imaging(EPI)-DWI before and after intravenous CM.EPI-DWI was acquiredtwice in 203 consecutive patients before and after i.v.CM.Three blinded readers rated the diagnostic | Fitzek C Mentzel HJ Fitzek S Sauner D Kaiser WA Reichenbach JR | 2003 | 中国神经肿瘤杂志2003，1，4： | 15 |
| 2 | A tale of worldwide success:Behind the scenes of Carex(Cyperaceae)biogeography and diversification显示文摘The megadiverse genus Carex(c.2000 species,Cyperaceae)has a nearly cosmopolitan distribution,displaying an inverted latitudinal richness gradient with higher species diversity in cold-temperate areas of the Northern Hemisphere.Despite great expansion in our knowledge of the phylogenetic history of the genus and many molecular studies focusing on the biogeography of particular groups during the last few decades,a global analysis of Carex biogeography and diversification is still lacking.For this purpose,we built the hitherto most comprehensive Carex-dated phylogeny based on three markers(ETS-ITS-matK),using a previous phylogenomic Hyb-Seq framework,and a sampling of two-thirds of its species and all recognized sections.Ancestral area reconstaiction,biogeographic stochastic mapping,and diversification rate analyses were conducted to elucidate macroevolutionary biogeographic and diversification patterns.Our results reveal that Carex originated in the late Eocene in E Asia,where it probably remained until the synchronous diversification of its main subgeneric lineages during the late Oligocene.E Asia is supported as the cradle of Carex diversification,as well as a< | Santiago Martin-Bravo Pedro Jimenez-Mejias Tamara Villaverde Marcial Escudero Marlene Hahn Daniel Spalink Eric H.Roalson Andrew L.Hipp the Global Carex Group Carmen Benitez-Benitez Leo P.Bruederle Elisabeth Fitzek Bruce A.Ford Kerry A.Ford Mira Gamer Sebastian Gebauer Matthias H.Hoffmann Xiao-Feng Jin Isabel Larridon Etienne Ldveilld-Bourret Yi-Fei Lu Modesto Luceno Enrique Maguilla Jose Ignacio Marquez-Corro Monica Miguez Robert Naczi Anton A.Reznicek Julian R.Starr | 2019 | Journal of Systematics and Evolution2019，57，6： | 6 |
