弹性

In this paper we study the deformation and stability of a planar elastica. One end of the elastica is clamped and fixed in space. The other end of the elastica is also clamped, but the clamp itself is allowed to slide along a linear track with a angle different from that of the fixed clamp.

As mentioned earlier, elastinolysiss thought to be an essential component of emphysema.3 This is supported by both pathophysiologic and biochemical investigations, which show reduced lung elastic recoil, disrupted elastic tissue structure, higher circulating levels of elastin peptide breakdown products, and higher levels of desmosine in urine and lung secretions.3 Of the macrophage-derived MMPs identified in emphysematous and COPD tissue, the gelatinases MMP2 and MMP9 are elastinolytic.

正如早些时候提及的，elastinolysiss被认为是肺气肿的主要成份之一。这可以由病理生理研究与生化研究所证实，这两项研究同时提示肺弹性活力的降低，弹性组织结构的断裂，弹力蛋白肽分解产物循环水平的增高，以及尿与肺脏分泌物中锁链素水平的增高。在气肿型或COPD组织中，经确定的巨噬细胞源性的金属蛋白酶中，elastinoly的MMP2与 MMP9是elastinolytic。
