The combinational effect of cardiac and biochemical markers in diabetic patients with cardiovascular disease [PDF]

, 2011
Background: Clinicopathological correlations, as well as several angiographic studies, suggest that diabetic patients have more extensive atherosclerotic disease, affecting the coronary arteries in particular.

Severe Vasoplegic Syndrome Treated with Angiotensin II and Hemoadsorption Therapy after Cardiac Surgery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Vasoplegic syndrome (VS) is a common complication after cardiac surgery with cardiopulmonary bypass (CPB). The main pathophysiology mechanism of VS includes a systemic inflammatory response syndrome due to surgical trauma, release of pro‐inflammatory mediators caused by blood contact with foreign surfaces of heart‐lung machine (pump and tubing)

Steric blocking upside down: a different way of thinking about the competition between myosin and tropomyosin

Frontiers in Physics
At low free Ca2+, the actin binding proteins tropomyosin, troponin I, troponin T and troponin C inhibit contraction in striated muscles. Ca2+ activation alters the position of tropomyosin on actin to uncover binding sites for high affinity forms of ...

Structural Kinetics of Cardiac Troponin C Mutants Linked to Familial Hypertrophic and Dilated Cardiomyopathy in Troponin Complexes*

Journal of Biological Chemistry, 2008
The key events in regulating cardiac muscle contraction involve Ca2+ binding to and release from cTnC (troponin C) and structural changes in cTnC and other thin filament proteins triggered by Ca2+ movement.

Luminescence and Electroanalytical Properties of Carbon Quantum Dots in the Context of Immunosensor Design

ChemElectroChem, Volume 12, Issue 6, March 15, 2025.
Two types of carbon quantum dots (CQD‐COOH and CQD‐NH2) are used to modify screen printed carbon electrodes, for detection of Cardiac Troponin I (cTnI). These modified sensors offer promising results for the determination of cTnI in the picomolar range, when, using an immunosensor protocol.

A novel mutant cardiac troponin C disrupts molecular motions critical for calcium binding affinity and cardiomyocyte contractility.

Biophysical Journal, 2008
Troponin C (TnC) belongs to the superfamily of EF-hand (helix-loop-helix) Ca(2+)-binding proteins and is an essential component of the regulatory thin filament complex.

Laser‐Induced Graphene for Early Disease Detection: A Review

ChemElectroChem, Volume 12, Issue 6, March 15, 2025.
Laser‐induced graphene (LIG) has emerged as a superior alternative to conventionally synthesized graphene due to its flexibility, cost‐effectiveness, scalability, high conductivity, and the ability to customize its properties for various applications. This review highlights LIG′s transformative potential in electrochemical biosensing, focusing on early

Molecular mechanisms of the regulation of ATPase cycle in striated muscle [PDF]

, 2007
New data on the molecular mechanism of the regulation of ATPase cycle by troponin-tropomyosin system have been obtained in reconstructed muscle fibers by using the polarized fluorescence technique, which allowed us following the azimuthal movements of ...
