Blood clotting: Calcium is required for the coagulation cascade, a series of biochemical reactions that lead to the formation of blood clots. Without sufficient calcium, blood clotting may be ...

The activation of prothrombin to thrombin, like several other reactions in the coagulation cascade, requires the presence of phospholipid and calcium. These phospholipid-dependent reactions are ...

This is because calcium repletion reactivates the clotting cascade and calcium infused into the return line increases the risk of clotting within the catheter and the loss of the circuit due to ...

See Figure 1 for a depiction of normal hemostasis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of ...

This study showed that FXa activity, an important part of the coagulation cascade that is the target of drug treatments, could be quantitatively assessed by DBCM, a method that is easy to use and ...

and initiate the activation of the coagulation cascade when they come into contact with blood. Analyses by the study authors confirm that mucosal bleeding in the mouth of these patients is indeed ...

They have found that X-rays trigger a calcium signaling cascade in cells of the immune system. The results have now been published in the Journal of General Physiology. More information ...

Synthetic phototransduction cascade. Blue light changes the conformation of melanopsin, which sequentially activates the enzymes PLC and PKC. This triggers the influx of calcium ions by activating ...
