A Test in Context: D-Dimer

Journal of the American College of Cardiology, 2017
D-dimer is a soluble fibrin degradation product that results from ordered breakdown of thrombi by the fibrinolytic system. Numerous studies have shown that D-dimer serves as a valuable marker of activation of coagulation and fibrinolysis. Consequently, D-dimer has been extensively investigated for the diagnosis of venous thromboembolism (VTE) and is ...

D-Dimer Testing in Pregnancy [PDF]

Pathophysiology of Haemostasis and Thrombosis, 2003
Normal pregnancy is associated with alterations of the hemostatic system toward a hypercoagulable state. Elevated markers of coagulation and fibrinolytic system activation, such as D-dimer, indicate increased thrombin activity and increased fibrinolysis following fibrin formation throughout pregnancy.

Failure mechanism analysis and process improvement on time-dependent dielectric breakdown of Cu/ultra-low-k dielectric based on complementary Raman and FTIR spectroscopy study

AIP Advances, 2014
Time-dependent dielectric breakdown (TDDB) is one of the most important reliability issues in Cu/low-k technology development. With continuous technology scalings to nanometer scales, TDDB issue is further exacerbated.
