This active protein then proteolytically cleaves and activates the next clotting factor, and so on.

然后这一活化的凝血因子激活另一个未活化的凝血因子，以此类推。

Unregulated inflammation means lots of proteases, platelet activating factor, and free radicals floating around the gastrointestinal tissue which ultimately causes destruction of healthy tissue.

不受控的炎症反应意味着大量的蛋白酶、血小板活化因子和自由基在胃肠道组织中流动，最终导致正常组织的破坏。

A new study finds that shining a low-power laser on damaged rat teeth activates molecular growth factors already present in the tissue.

一项最新的研究发现低能量激光照射过损伤的老鼠牙齿后能激活已经存在于组织中的生长因子。

The cytokines attract Inflammatory cells like macrophages which start releasing even more inflammatory substances like proteases, platelet activating factor, and free radicals, all which contribute to inflammation.

这些细胞因子可以募集更多的炎症细胞如巨噬细胞；这些巨噬细胞进而释放更多的炎症介质，如蛋白酶、血小板活化因子和自由基，它们都可以进一步促进炎症反应。

Signs and symptoms hemophilia A and B are nearly clinically identical, which makes sense since factors VIIIa and IXa work together in the coagulation cascade to activate factor X.

血友病A和B的体征和症状在临床上几乎相同，也说得通，因为因子VIIIa和IXa在凝血级联反应中，共同作用以激活因子X。

Procoagulants could be proteins like tissue factor or bacterial components like lipopolysaccharide, or could even be the presence of enzymes that help to proteolytically cleave and activate clotting factors.

促凝因子可以是类似组织因子的蛋白质，或者类似脂多糖的细菌成分，甚至可以是帮助蛋白酶切割和活化凝血因子的酶。

Tissue factor turns inactive factor VII into activate factor VIIa (a for active), and then tissue factor goes on to bind the newly formed factor VIIa to form a complex that turns factor X into active factor Xa.

组织因子使无活性的因子VII转变为活性因子VIIa，之后组织因子结合新形成的因子VIIa，形成一个复合物将因子X转变为活性因子Xa。
