Synthesis of Elastin Graft Copolymer via ATRP and Its Properties

ATRP法合成弹性蛋白接枝共聚物及其性能研究

The polypepticle chains in elastin are present in a random arrangement

弹性蛋白内的多肽链以一种纹乱的排列而存在。

Collagen and elastin provide the strength and resiliency of connective tissues such as skin and ligaments

胶原和弹性蛋白使象皮肤和韧带这样的结缔组织具有韧性和弹性。

Modification of Elastin via Thio-iniferters

硫代-iniferters法改性弹性蛋白的研究

Ligaments contain protein elastin

韧带还含有弹性蛋白。

They have a yellowish color owing to the accumulation of elastin in the media

因中膜中含有很多弹性纤维所以呈黄色。

||1:The animal experiments suggest the new, all-collagen vessels are capable of lasting at least a year without noticeable deterioration.||2:They are also, once implanted, able to remodel themselves in ways that improve their function—changing shape in response to blood flow, being colonised by cells from the patient's body, and showing signs of incorporating elastin , another structural protein found in natural vessels.

||1:动物实验表明，新型全胶原蛋白的血管有能力至少维持一年而没有明显恶化。||2:一旦植入，它们也能按照提高其功能的方式自我改造——针对血流改变形状，让病患的身体细胞在其上生长，并显示出混合了天然血管中发现的另一个结构蛋白弹性蛋白的迹象。

The first was protein-polymer combinations for elastin , which is found in connective tissue.

第一个蛋白质聚合体是用于弹性蛋白的，其生长在相关联的组织中。

It also increases inflammation which can damage collagen and elastin leading to skin wrinkling and sagging.

酒精还可以加重炎症，从而破坏皮肤胶原和胶原蛋白，同样会让皮肤产生松弛下垂。

Smoking damages the elastin that helps keep facial skin flexible.

吸烟会破坏帮助皮肤保持弹性的弹性蛋白。

Improved exchange between cells promotes proliferation which improves collagen and elastin levels in the skin.

细胞间的改进的交换促进了细胞繁殖，而细胞繁殖可以提升皮肤中胶原蛋白及弹性蛋白的水平。
