    Aim: Contraction of cardiac myocytes is controlled by the generation and amplification of intracellular Ca2+ signals. The key step of this process is the coupling between sarcolemma L-type Ca2+ channels (LCCs) and ryanodine receptors (RyRs) in the sarcoplasmic reticulum (SR). �-Adrenergic...

    The article focuses on age-dependent changes in the effects of amiodarone on rabbit cardiac myocyte contractions. It says that the drug inhibits caffeine-induced contraction in neonatal myocytes but has no influence on adult myocytes. Sarcoplasmic reticulum (SR) Ca2+ stores in neonatal heart can...

    Abstract: Objective: The multifunctional Ca2+-binding protein S100A4 (also known as Mts1 and Fsp1) is involved in fibrosis and tissue remodeling in several diseases including cancer, kidney fibrosis, central nervous system injury, and pulmonary vascular disease. We previously reported that...

    The article discusses the activity of SERCA2a, a crucial membrane protein located inside cardiac muscle cells. It emphasizes that it acts as a calcium-ion pump that has the potential to correct the mishandling of calcium ions which causes the heart to malfunction. It stresses that its attachment...

    Phosphate depletion is associated with a rise in cytosolic calcium ([Ca2+]i) of cells and such a derangement is responsible in major part for organ dysfunction in phosphate depletion (PD). Cardiac function is impaired in PD, and it is possible that PD is also associated with rise in [Ca2+]i of...

    Cardiac repolarization alternans is a rhythm disturbance of the heart in which rapid stimulation elicits a beat-to-beat alternation in the duration of action potentials and magnitude of intracellular calcium transients in individual cardiac myocytes.

    Aims SR33805, a potent Ca2+ channel blocker, increases cardiac myofilament Ca2+ sensitivity in healthy rat cardiomyocytes. Therefore, the aim of the present study was to evaluate the effects of SR33805 on contractile properties in ischaemic failing hearts after myocardial infarction (MI) in vivo...

    The mean sarcomere length (SL) of guinea-pig cardiac myocytes was recorded simultaneously with the whole-cell current under voltage-clamp conditions. After blocking both sarcoplasmic reticulum (SR) and L-type Ca2+ channels with ryanodine, cyclopiazonic acid and nicardipine, strong depolarizing...
