Our aim was to establish whether differences in clotting times for recalcified blood and plasma samples might be explained by the use of different blood collection tubes. Samples obtained from different plastic vacuum tubes were recalcified and clotting times determined by free oscillation rheometry. The clotting times for blood collected in Vacutainer (Becton Dickinson, Rutherford, New Jersey,...

The identification of the blood-clotting inhibitor, protein S, as a ligand for a previously 'orphan' family of receptor tyrosine kinases demonstrates a new role for clotting and anti-clotting proteins in regulating cell proliferation.

Purpose: To evaluate the association between platelet inhibition rate of clopidogrel (CLO-PIR) and post-extraction clotting status in DAPT patients.
 Methods: Ninety (90) eligible patients scheduled for a single tooth extraction were enrolled this study. The CLO-PIR aspirin (ASA-PIR) determined by thromboelastography mapping assay. Post-extraction assessments performed, complete intra-alve...

Tissue factor (TF), the initiator of coagulation, continuously circulates in the plasma, and the clotting system "idles," generating very low levels of active clotting enzymes, clotting products, and by-products. Given the enormous amplification potential of the clotting cascade, rigorous control is required to ensure that such low-level stimulation does not cause massive system amplification a...
