چکیده
reports dealing with the higher affinity of Hp 2-2, compared with Hp 1-1, for the CD163 receptor on macrophages. The more efficient uptake of the multimeric Hp molecules is reflected in the serum concentrations of free Hb. The observed differences in free Hb between Hp phenotypes could help to explain the previously reported differences in oxidative stress markers among Hp phenotypes (3, 10). In conclusion, we observed a marked relationship between free Hb concentrations in serum and Hp phenotypes. These findings further support the view of multimeric Hp forms in the clearance of the free Hb. In this regard, the Hp polymorphism is another caveat in the interpretation of free Hb values.

Objective: Acute chest pain is an important and frequently occurring symptom in patients. Chest pain is often a sign of ischemic heart disease. Chest pain due to suspected Acute Coronary Syndrome (ACS) is responsible for a large and ijncreasing number of hospital attendances and admissions. Current practice for suspected ACS involves troponin testing 10–12 hours after symptom o...
متن کاملAnalysis of the relation between coping ways with stress and Cardiac Biomarker Troponin I in coronary heart disease patients
Introduction: Coping ways with stress in coronary heart disease patients can lead to significant changes in levels of Cardiac Biomarker Troponin I, but researchers had not explored it empirically. So, the main objective of this study was to identify the relationship between coping ways with stress and Cardiac Biomarker Troponin I and also, finding coping ways that predict changes in the concent...
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...

متن کاملTroponin testing at the point of care: What is needed, and when?
The ability to measure the cardiac troponins (cTnI and cTnT) has produced a paradigm shift in the assessment of patients with suspected acute coronary syndromes (ACS). The availability of immunoassays for cardiac troponins, a milestone in the care of patients with chest pain, led to two new definitions of myocardial infarction and to the publication of several position papers and guidelines [1-3].
متن کاملSertraline alters level of adenosine deaminase activity, oxidative stress markers and cardiac biomarkers (homocysteine cardiac troponin I) in rats
The aim of this study is whether oxidative stress markers, homocysteine (Hcy), cardiac troponin I (cTnI) and the activity of adenosine deaminase (ADA) alter following administration of different doses of sertraline. Sixty male Wistar rats were assigned into four groups. Sertraline at doses of 20, 40 and 80 mg / kg / day) were administered to three groups through gastric gavage for 90 days. The ...
