2Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction.Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício 2015World Journal of Stem Cells2015,7,6:2
3承受轴向、弯曲、剪切和扭曲组合荷载的钢筋混凝土和预应力混凝土的三维数值模型显示文摘提出了钢筋混凝土和预应力混凝土承受组合荷载下的分析模型,荷载包括轴力、双向弯矩、扭矩和双向剪力。所提出的模型基于Timoshenko梁理论的简单动力假设,保持了任意截面尺寸情况下的三维框架的形状。框架的控制截面被细分为一维,二维和三维材料响应。钢筋混凝土和预应力混凝土构建的材料模型遵循用切线刚度公式表示的改进压缩场理论的基本假设。通过其结果与文献中几个著名的试验相比较验证了模型的正确性。这些模拟包括弯曲、剪力和扭矩一系列变化的荷载组合。分析结果显示,试件的极限强度以及从初始裂缝到最终荷载的局部应变响应与试验结果十分吻合。J.
