High-sensitivity cardiac troponins: circadian rhythms

High-sensitivity assays for cardiac troponins.

This issue of Clinical Chemistry and Laboratory Medicine (CCLM) devotes a large section to the cardiac troponins (cTn) and in particular to the impact of the novel high sensitivity (hs) assays on clinical practice. Furthermore, several articles deal with known or novel pitfalls of hs-cTn in clinical diagnostics. While there is no doubt that the hs-cTn assays constitute a significant analytical ...

Consensus statement on the use of high sensitivity cardiac troponins

The increased sensitivity of high sensitivity cardiac troponin assays comes at a cost of decreased specificity, and “false positive” diagnosis of acute coronary syndromes has made clinicians wary of their use, fearing unnecessary hospitalisations, angiography and revascularisation. The Ethics and Guidelines Standing Committee of SA Heart Association convened a meeting of cardiologists, chemical...

The survey of fluctuations of attention on circadian and weekly rhythms among high school students

Introduction: Human cognitive activities are affected by the time of doing homework, biologic rhythms and interaction among them.  Method: this research accomplished to specify the fluctuation patterns of daily and weekly cycles of the students attention. The research method was correlation. The statistical population of this study were 45 female students in 11th grade from a high school in hu...
