Multiple electrode aggregometry and ADP-receptors. Adding ASA (acetylsalicylic acid) reagent to a blood sample reduces the aggregation responses in ASPItest and COLtest. ASA irreversibly inhibits COX1 in platelets, thereby inhibiting the production of TXA2. The ASA Reagent is used as a quality control in the platelet function testing with Multiplate, allowing the assessment of abnormal platelet responses in ASPItest and COLtest. This reagent is used as a quality control in Multiplate platelet function testing. The GPIIb/IIIa antagonist blocks the binding of fibrinogen to the GPIIb/IIIa receptors, preventing the formation of platelet-fibrinogen bonds and resulting in significantly reduced platelet aggregation in response to all
Bark hack The first sentence is basically correct except that the blade is straight rather than curved. With the bark hack, only the bark is removed; it does not cut into the wood as the wood hack did. The wood hack was used up until the early 1950's and the trees were "chipped or streaked" each week during the sap flow season. With the bark hack, only the bark was removed and a 50% sulfuric acid solution was sprayed on the "streak" and it had to be done only every 2 weeks. Bark hack A bark hack is a tool used to
