摘要:
Disclosed are compositions for treating blood coagulation disorders and allows for manipulation of the blood coagulation cascade. More particularly the invention, relates to compositions for altering bleeding that include a mixture of at least one blood coagulation factor in a low dose and phospholipid vesicles. The invention has a variety of important uses including controlling bleeding in a mammal that has or is suspected of having a potentially life-threatening blood coagulation disorder.
摘要:
The invention provides compositions and methods for the detection of Factor XIa or Tissue Factor (TF) activity in a sample using an antibody based clotting time prolongation assay. The invention provides methods for detection of FXIa or TF activity in a sample using a fluorogenic substrate. Further provided herein is a correlation between elevated levels of FXIa and/or TF with inflammation, acute coronary syndrome (ACS), myocardial infarction, coronary artery disease (CAD), heart failure, aortic stenosis, stroke, or transient ischemic attack. The frequency of FXIa and TF activity was substantially lower in individuals with stable coronary artery disease and no history of myocardial infarction. No FXIa or TF activity was observed in healthy individuals.

摘要:
The instant invention describes a method for establishing the hemostatic competence of blood, wherein the steps of the method include obtaining a blood sample from a subject, contacting the blood sample with an effective amount of tissue factor under conditions conducive to coagulating blood; and detecting the amount of thrombin in the blood sample at a pre-determined time point. The invention also describes a method for testing the capacity of an individual subject to produce thrombin, wherein the steps of the method include obtaining a blood sample from the subject; contacting the blood sample with an effective amount of tissue factor under conditions conducive to coagulating blood; and detecting the amount of thrombin produced in the blood sample at a pre-determined time point.
摘要:
Disclosed are antibodies that selectively bind to blood coagulation factor FVIII, and highly sensitive immunological assays comprising these antibodies. Preferred assays can detect FVIII at about 3500-fold below the normal physiological levels, and have a wide array of applications including accurate monitoring of FVIII concentration in pharmaceutical products for treatment of blood coagulation disorders, and determination of FVIII levels in plasma of human patients, including those with blood coagulation disorders such as hemophilia.
摘要:
The present invention provides methods for inhibiting blood clotting. In general, the methods include adding corn trypsin inhibitor (CTI) to blood or a blood product in an amount sufficient to inhibit the clotting. The CTI can be used alone or in combination with other anti-coagulants. In one aspect, the invention features plasma clotting assays featuring substantially prolonged clotting times. Clotting assays using whole or minimally altered blood are also provided. Further provided are methods for storing blood or blood products at low temperature with the CTI.
摘要:
The present invention features isolated angiogenesis inhibitors having a molecular weight of between about 40 kDa to 50 kDa and having an amino acid sequence substantially similar to that of the amino acid sequence shown in SEQ ID NO. 2 or SEQ ID NO. 3. Further provided are methods of making and using the angiogenesis inhibitors, e.g., to inhibit vascularization or to block osteonectin and plasminogen interaction.

摘要:
Featured are methods for assessing hemostatic risk including the risk for ACS. Such methods include acquiring blood/plasma composition based on a biological sample obtained from a subject, determining parameters associated with blood clotting, simulating in silico blood clotting using the determined parameters and comparing the results of such simulation to a reference and to determine the hemostatic risk from said comparing. In further embodiments, such methods further include selecting a treatment regime or protocol based on the results of such comparing. In yet further embodiments, such methods further include assessing the efficacy of medicants, drugs and the like of a given treatment protocol such as by simulating in silico the application of such medicants, drugs and the like.
