Coagulation and platelet biology at the intersection of health and disease: illustrated capsules of the 11th Symposium on Hemostasis at the University of North Carolina.

Conference Res Pract Thromb Haemost · March 2024 The University of North Carolina Symposia on Hemostasis began in 2002, with The First Symposium on Hemostasis with a Special Focus on FVIIa and Tissue Factor. They have occurred biannually since and have maintained the primary goal of establishing a forum ... Full text Link to item Cite

Mechanism of Complement Activation By PF4/ Heparin Complexes

Conference Blood · December 2, 2016 AbstractThe mechanisms underlying the PF4/heparin immune response are poorly understood. In recent studies, we showed that PF4/heparin complexes, but not PF4 alone or heparin alone, activate complement (C') ... Full text Cite

Novel ELISA-Based Assay for Detection of Complement Activation By PF4/Heparin Complexes

Conference Blood · December 2, 2016 AbstractThe immune response to platelet factor 4 (PF4)/heparin complexes is a frequent iatrogenic complication of heparin therapy associated with development of heparin-induced thrombocytopenia (HIT). Our re ... Full text Cite

RNA Aptamer Against FXa Synergizes with FXa Catalytic Site Inhibitors to Effectively and Reversibly Anticoagulate Blood in an Ex Vivo Oxygenator Circuit

Conference Blood · December 2, 2016 AbstractDespite notable disadvantages, unfractionated heparin (UFH) remains the standard anticoagulant for clinical procedures requiring potent and reversible anticoagulation such as cardiopulmonary bypass ( ... Full text Cite

The Thrombotic Microangiopathy Registry of North America

Conference Blood · December 3, 2015 AbstractThe thrombotic microangiopathies (TMAs) are rare, life-threatening thrombotic disorders of diverse etiologies. Systematic studies of TMA have been difficult to perform due to their rare occurrence, d ... Full text Cite

Characterization of Human and Murine Anti-Protamine/Heparin Antibodies

Conference Blood · December 3, 2015 AbstractProtamine/heparin (PRT/H) antibodies (Abs) are a newly described class of heparin-dependent antibodies found in ~25% of patients exposed to protamine and heparin during cardiopulmonary bypass surgery ... Full text Cite

Predicting the Temporal Course of Laboratory Abnormality Resolution in Patients with Thrombotic Microangiopathy

Conference Blood · December 6, 2014 AbstractBackground:Screening for deficiency of ADAMTS- 13, a von Willebrand factor-cleaving protease, is commonly performed when there exists a clinical suspicion for thrombo ... Full text Cite

Biologic Activities of Protamine/Heparin Antibodies

Conference Blood · December 6, 2014 AbstractProtamine/heparin (PRT/H) antibodies (Ab) are a newly described class of heparin-dependent Abs found in ~25% of patients exposed to protamine and heparin during cardiopulmonary bypass surgery (CPB). ... Full text Cite

High Incidence of Antibodies to Protamine and Protamine/Heparin Complexes in Patients Undergoing Cardiopulmonary Bypass

Conference Blood · November 16, 2012 AbstractAbstract 3344INTRO:Protamine (PRT) is routinely used to reverse heparin (H) anticoagulation d ... Full text Cite

Novel Techniques for Measurement of Variable Sized PF4/H Complexes.

Conference Blood · November 16, 2012 AbstractAbstract 2204Electrostatic interactions between Platelet factor 4 (PF4), a cationic protein, and heparin, an anionic carbohydrate result in the formation of ultra-lar ... Full text Cite

PF4/H Complexes Induce Germinal Centers in Vivo

Conference Blood · November 16, 2012 AbstractAbstract 269Mice injected with ultra-large complexes (ULCs) of platelet factor-4 (PF4) and heparin (PF4/H) exhibit a strong immune response which mimics that seen in ... Full text Cite
