The freezing and drying bone still seems a fitting substitute among them . nowadays , as a commodity , immunological rejection of freezing and drying bone has seldom seen and cell - based bong tissue engineering has emerged as a promising alternative for bone repair 其中,基质材料尚无标准材料;活性因子,如骨形成蛋白等受多种因素的影响;血管化复合组织工程骨程序过于复杂和昂贵。
The results of the application of kii model on the classification of one - dimensional binary series are presented . the cell - based biosensor using fet array provides a non - invasive way for recording the active potential real time , and it can be reach to a single cell 基于场效应管阵列的细胞传感器是一种无损测量细胞动作电位的器件,可以定位到单个的细胞,实现实时检测外界电刺激作用下的膜电位的改变。
The task is to investigate the molecular biology mechanism of shear stress - mediated enhancement in endothelial progenitor cells function for repair of vascular injury , which will provide new method for cell - based cell therapy of vascular injury with endothelial progenitor cells 通过建立多种实验模型,研究切应力增强内皮祖细胞功能活性,提高其修复血管损伤的分子生物学机制,为以内皮祖细胞为基础的细胞疗法修复血管损伤寻找新策略。
Cells provide an array of naturally evolved receptors , ion - channels , enzymes that may be targets of biological or biologically active analytes . cell - based biosensors that treat cells as biological sensing elements have the capacity to respond to analytes in a physiologically relevant manner . such biosensors have numerous applications including pharmaceutical screening and physiological analysis 细胞拥有并表达着一系列分子识别元件,如受体、离子通道、酶等,这些分子都可以作为靶分析物,当它们对外界刺激敏感时,就按照固有的活细胞生理机制进行相应的生理功能活动。
By analyzing the microstructure , the digitized cell model of three - dimensional four - directional composites is established , then the mechanic properties of three - dimensional four - directional composites are calculated by the digitized cell - based finite element method ( dcb - fem ) , and the influence of the braiding angle and the fiber volume fraction is discussed 摘要在确立三维四向编织复合材料数字化单胞力学分析模型的基础上,运用均匀化方法对三维编织复合材料的等效弹性性能进行了分析计算,并讨论了编织角和纤维体积含量对此材料等效弹性性能的影响。
