Association between troponin-I levels and outcome in critically ill patients admitted to non-cardiac intensive care unit with high prevalence of cardiovascular risk factors

BMC Anesthesiology, 2018
Background The association of troponin-I levels and outcome in medical-surgical ICU patients has been studied before in populations with low to moderate prevalence of cardiovascular risk factors.

Characterization of a Cardiac Troponin C-Troponin I Chimera Protein [PDF]

Biophysical Journal, 2013
Association of the regulatory N-domain of cardiac troponin C (cNTnC) with the switch region of cardiac troponin I (cTnI147-163) is a major step in Ca2+ regulation of myocardial contraction by troponin as it triggers a series of downstream events that leads to contraction.

Leveraging Design of Experiments to Unravel the Amplification Mechanism of Single‐Molecule Wide‐Field Biosensors

Advanced Materials Interfaces, EarlyView.
Detecting single molecules on large interfaces is challenging due to minimal perturbations on the sensing surface. Some biological systems achieve this feat using amplification mechanisms, but their molecular foundations remain unclear. To investigate, a Design of Experiments (DoE) approach examines how pH and ionic strength in conditioning solutions ...

Label‐Free, Sensitive, and Direct Detection of Cardiac Troponin Biomarkers Using Frequency‐Locked Microring Resonators

Advanced Sensor Research, EarlyView.
A deployable, chip‐integrated approach to the detection of heart attack biomarkers is demonstrated using silicon photonic microring resonators combined with microfluidics. By applying the Pound–Drever–Hall frequency locking technique, sensor signals are measured with improved signal‐to‐noise ratio, applying this to real‐time, selective readouts.

Cardiac troponin I (CTnI) level among children with epileptic seizures

The Egyptian Heart Journal, 2014
Epilepsy is a common chronic neurological disorder in pediatric age characterized by recurrent, unprovoked seizures; these seizures are transient signs of abnormal excessive or hyper synchronous neuronal activity in the brain.
