High-sensitive cardiac troponin T
Cardiac troponin is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). The recent development of a high-sensitive cardiac troponin T (hs-cTnT) assay permits detection of very low levels of cTnT. Using the hs-cTnT assay improves the overall diagnostic accuracy in patients with suspected AMI, while a negative result also has a high negative predictive value. The gain ...
متن کاملDephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation. Isolated rat cardiac myofibrils phosphorylated by PKC/PKA and dephosphorylated by PP1 were used in determining dephosphorylation specificities, Ca(2+)-stimulated Mg(2+)ATPase activities, and Ca(2+) sensi...
متن کاملHydrodynamic properties of bovine cardiac troponin-I and troponin-T.
Bovine cardiac troponin-I (TN-I) and troponin-T (TN-T) have been examined in solution using ultracentrifugation, gel filtration, and viscosity. A new method of purifying TN-T, employing hydroxylapatite chromatography in 6 M urea, is reported. Cardiac TN-T (Mr = 36,000) undergoes a reversible, concentration-dependent association in nondenaturing buffers, probably to a tetramer. The Stokes radius...
متن کاملValues of troponin T and myoglobin predictive of non-cardiac ischemia in rats
Objective(s):Biochemical markers are important for the timely diagnosis and follow-up of ischemic events. Most of the markers have been previously studied in the context of cardiac ischemia. However, research on markers of non-cardiac events has been insufficient. Therefore, we investigated the relationship between troponin and myoglobin which are commonly used markers of cardiac ischemia, in n...
