activation

The tissue factor and contact activation pathways merge after activation of clotting factors VIII, IX and X, forming the common pathway.

Molecular mechanism of complement activation on polymer surfaces: contact activation of reconstituted first component (CI) of classical pathway, in Advances in Biomaterials, eds.

Contact activation of blood generates kallikrein, an enzyme that can convert kininogens into kinins.

One of the inherent risks is contact activation, where blood interfaces with the CPB unit and can activate the kallikrein system, leading to untoward systemic inflammatory responses.

Image sequences are recorded on detection or with external dry contact activation.
