The primary action of aspirin is to:
1) Increase blood flow
2) Decrease blood pressure
3) Inhibit thrombin
4) Inhibit platelet aggregation via thromboxane A2
Aspirin exerts its anti-inflammatory and anti-platelet effects by irreversibly inhibiting cyclooxygenase (COX) enzymes, particularly COX-1. This inhibition leads to decreased synthesis of thromboxane A2, a potent mediator of platelet aggregation and vasoconstriction. By blocking thromboxane A2, aspirin helps prevent the formation of blood clots, thus reducing the risk of thrombotic events such as heart attacks and strokes.

Which of the following is not true about casting gypsum-bonded investment material?
1) Its used for cast metal alloys
2) 50—65% of gypsum changes to form α-hemihydrate
3) The investment material is not heated above 700°C temperature
4) Heating above 700°C causes formation of sulphur dioxide from copper sulphate
Gypsum-bonded investments are used for gold alloys.
Ist investments flow contain the α-hemihydrate of gypsum. because greater strength is obtained. This gypsum
product serves as a binder to hold other ingredients together and provide rigidity. The strength of the investment is dependent on the amount of binder present.
A slight expansion takes place between 400°C and approximately 700°C (1292°F). and then a large contraction occurs. This later shrinkage is most likely caused by decomposition and release of sulphur gases, such as sulphur dioxide.
This decomposition not only causes shrinkage but also contaminates the casting with the sulphides of the nonnohlc alloying elements, such as silver and copper. Thus, it is imperative that gypsum investments should not be heated above 700°C (1292°F). however, for gypsum products containing carbon, the maximum temperature should be 650°C (1202°F). In this way, proper ut and uncontaminated alloys are obtained.
