Methods and assays for determining the activation level of the plasma kallikrein (pKal) system and the uses thereof for assessing the activity of pKal modulators on the pKal system.

The invention relates to inhibitory anti-factor XII/FXIIa antibodies and methods of their use.

The invention pertains to a blood coagulation factor replacement product for use in the treatment or prophylaxis of bleedings of patients having an acquired coagulation factor deficiency or for use in the treatment or prophylaxis of bleedings of patients having a congenital deficiency of a coagulation factor. Said product comprises at least isolated prothrombin (Factor II) and isolated Antithrombin III (ATIII), whereby the molar ratio between ATIII to Factor II is at least 1:30. By administration of said product the patient's risk for a thromboembolic complication is reduced.

Provided are a Haemadipsa sylvestris antithrombotic peptide Sylvestin and the use thereof, falling within the technical field of biomedicine. The Haemadipsa sylvestris antithrombotic peptide sylvestin can inhibit FXIIa and kallikrein, has anti-thrombus/infarction effects and alleviates injuries caused by cerebral ischemia, and can also be used in the preparation of inhibitors of FXIIa and kallikrein and drugs for anti-thrombus/infarction and anti-cerebral ischemic injuries.

This invention is directed to a vector which comprises a promoter operably linked to a nucleic acid sequence encoding the human C1 esterase inhibitor or Factor XII. The invention is also directed to a composition comprising the vector and a method of using the vector to treat or prevent hereditary angioedema.
