Background: The rate-limiting step of cardiac muscle relaxation is not completely understood. Results: We were able to measure two proposed rate-limiting steps of relaxation in ventricular myofibrils.

Engineered Troponin C Constructs Correct Disease-related Cardiac Myofilament Calcium Sensitivity*
Background: Improved myofilament Ca2+ sensitivity alleviates defects in thin filament bearing disease-causing mutations. Results: By engineering the cardiac muscle Ca2+ sensor troponin C, aberrant myofilament Ca2+ sensitivity can be corrected in vitro ...

The cardiac Ca-sensitive regulatory switch, a system in dynamic equilibrium [PDF]
The Ca-sensitive regulatory switch of cardiac muscle is a paradigmatic example of protein assemblies that communicate ligand binding through allosteric change. The switch is a dimeric complex of troponin C (TnC), an allosteric sensor for Ca, and troponin I (TnI), an allosteric reporter.

Investigating the role of uncoupling of troponin I phosphorylation from changes in myofibrillar Ca(2+)-sensitivity in the pathogenesis of cardiomyopathy. [PDF]
Contraction in the mammalian heart is controlled by the intracellular Ca2+ concentration as it is in all striated muscle, but the heart has an additional signalling system that comes into play to increase heart rate and cardiac output during exercise or ...

Type 2 myocardial infarction: the chimaera of cardiology? [PDF]
The term type 2 myocardial infarction first appeared as part of the universal definition of myocardial infarction. It was introduced to cover a group of patients who had elevation of cardiac troponin but did not meet the traditional criteria for acute ...

Risk markers by sex for in-hospital mortality in patients with acute coronary syndrome: a machine learning approach [PDF]
Background: Several studies have highlighted the importance of considering sex differences in the diagnosis and treatment of Acute Coronary Syndrome (ACS). However, the identification of sex-specific risk markers in ACS sub-populations has been scarcely studied.

Structure of trans-resveratrol in complex with the cardiac regulatory protein troponin C.
Cardiac troponin, a heterotrimeric protein complex that regulates heart contraction, represents an attractive target for the development of drugs for treating heart disease.
