1Spreading depression and focal venous cerebral ischemia enhance cortical neurogenesis显示文摘Endogenous neurogenesis can arise from a variety of physiological stimuli including exercise, learning, or 'enriched environment' as well as pathological conditions such as ischemia, epilepsy or cortical spreading depression. Whether all these conditions use a common trigger to set off endogenous neurogenesis is yet unclear. We hypothesized that cortical spreading depression(CSD) induces neurogenesis in the cerebral cortex and dentate gyrus after cerebral venous ischemia. Forty-two Wistar rats alternatively underwent sham operation(Sham), induction of ten CSDs or venous ischemia provoked via occlusion of two adjacent superficial cortical vein followed by ten induced CSDs(CSD + 2-VO). As an additional control, 15 na?ve rats received no intervention except 5-bromo-2′-deoxyuridine(Brd U) treatment for 7 days. Sagittal brain slices(40 μm thick) were co-stained for Brd U and doublecortin(DCX; new immature neuronal cells) on day 9 or Neu N(new mature neuronal cells) on day 28. On day 9 after sham operation, cell proliferation and neurogenesis occurred in the cortex in rats. The sole induction of CSD had no effect. But on days 9 and 28, more proliferating cells and newly formed neurons in the ipsilateral cortex were observed in rats subjected to CSD + 2VO than in rats subjected to sham operation. On days 9 and 28, cell proliferation and neurogenesis in the ipsilateral dentate gyrus was increased in sham-operated rats than in na?ve rats. Our data supports the hypothesis that induced cortical neurogenesis after CSD + 2-VO is a direct effect of ischemia, rather than of CSD alone.Ryo Tamaki Samuel Ige Orie Beat Alessandri Oliver Kempski Axel Heimann 2017Neural Regeneration Research2017,12,8:3

3On the cyclic behaviour of new pier-to-deck connections for short-medium span composite I-girder bridges显示文摘Short-medium span steeleconcrete composite I-girder bridges are becoming more and more popular, because of the reduced construction time and costs. The light weight renders them particularly suitable also is seismic areas, even though this advantage has not been yet adequately investigated. In fact, in case of seismic loading, significant tensile forces might be exhibited at the bottom flange of the steel girder, especially when monolithic connection between deck and pier is adopted, and the connection, conceived for sustaining prevailing hogging bending moments, could experience an excessive damage.With this aim, the cyclic behaviour of new pier-to-deck joints involving the use of concrete cross-beams(CCB) has been recently analysed within the European project(SEQBRI). This paper deals with the results of a wide experimental investigation of these new joints,performed with the aim of characterizing their hysteretic behaviour. Three different typologies were tested: one designed according to the German standard DIN-FB-104, generally utilized for gravity loads only, and other two types proposed for bridges located in low(VAR-1) and medium(VAR-2) seismicity. A series of displacement-imposed cyclic tests highlighted a good seismic behaviour of all the tested solutions. In particular, the DIN-FB-104 VAR C and VAR-2 displayed a similar global behaviour in terms of maximum force and displacement, but with a more pronounced crack development and buckling of steel girders of the first solution. The VAR-2 also avoids possible pull-out phenomena in the CCB thanks to the beneficial action of pre-stressing bars.A damage analysis of the proposed connections was finally performed in view of the application of the performance-based earthquake engineering methodology and the quantification the seismic performance of this bridge typology, which was among the aims of SEQBRI project.Fabrizio Paolacci Renato Giannini Silvia Alessandri Daniele Corritore 2018Journal of Traffic and Transportation Engineering(English Edition)2018,5,6:2
