Newly synthesized heparan sulfates purified from the cell layer of bovine aortic endothelial cells (BAECs) and main pulmonary artery endothelial cells (BPAECs) cultured under either normoxic (21% oxygen) or hypoxic (3% oxygen) conditions were characterized by size, charge, and capacity to bind to antithrombin III. Incorporation of radiolabeled sulfate into cell layer-associated heparan sulfate ...

OBJECTIVES Systemic inflammatory mediators, including the protein high-mobility group box 1 (HMGB1), play an important role in the development of acute pancreatitis. Anticoagulants, such as antithrombin III (AT III), inhibit inflammation resulting from various causes, but their mechanism of action is not well understood. Because acute pancreatitis is a severe inflammatory disease, we hypothesiz...

The diffusivities of thrombin and antithrombin III in a heparin-polyvinyl alcohol hydrogel were estimated and used to demonstrate that diffusion limits the effectiveness of the immobilized heparin in the interior of such hydrogels. Diffusivities were calculated from permeabilities and partition coefficients measured with films in a diffusion chamber apparatus. The diffusion coefficients were es...

BACKGROUND AND PURPOSE We studied the activities of the coagulation-fibrinolysis system in the chronic stage of poststroke patients and the effect of antiplatelet medication on the system. METHODS We determined fibrinogen, antithrombin III, thrombin-antithrombin III complex, tissue plasminogen activator antigen, plasminogen activator inhibitor-1, plasmin-alpha 2 plasmin inhibitor complex, and...
