Cardiac alternans and intracellular calcium cycling [PDF]
Clinical and Experimental Pharmacology and Physiology, 2014 SummaryCardiac alternans refers to a condition in which there is a periodic beat‐to‐beat oscillation in electrical activity and the strength of cardiac muscle contraction at a constant heart rate. Clinically, cardiac alternans occurs in settings that are typical for cardiac arrhythmias and has been causally linked to these conditions.

Over expression of Plk1 does not induce cell division in rat cardiac myocytes in vitro. [PDF]
PLoS ONE, 2009 BACKGROUND:Mammalian cardiac myocytes withdraw from the cell cycle during post-natal development, resulting in a non-proliferating, fully differentiated adult phenotype that is unable to repair damage to the myocardium, such as occurs following a ...

Learning the dynamics and time-recursive boundary detection of deformable objects [PDF]
, 2008 We propose a principled framework for recursively segmenting deformable objects across a sequence of frames. We demonstrate the usefulness of this method on left ventricular segmentation across a cardiac cycle.

Interactions between cardiac activity and conscious somatosensory perception
, 2019 Fluctuations in the heart's activity can modulate the access of external stimuli to consciousness. The link between perceptual awareness and cardiac signals has been investigated mainly in the visual and auditory domain. Here, we investigated whether the

Early Postnatal Cardiac Stress Does Not Influence Ventricular Cardiomyocyte Cell-Cycle Withdrawal
Journal of Cardiovascular Development and Disease, 2021 Congenital heart disease (CHD) is the most common birth defect. After birth, patients with CHD may suffer from cardiac stress resulting from abnormal loading conditions.

Thoracic aorta cardiac-cycle related dynamic changes assessed with a 256-slice CT scanner [PDF]
, 2013 Objective: The aim of our study was to demonstrate whether the dynamic changes previously documented at the ascending and abdominal aorta are replicated at the thoracic aorta.

RNAase III-Type Enzyme Dicer Regulates Mitochondrial Fatty Acid Oxidative Metabolism in Cardiac Mesenchymal Stem Cells [PDF]
, 2019 Cardiac mesenchymal stem cells (C-MSC) play a key role in maintaining normal cardiac function under physiological and pathological conditions. Glycolysis and mitochondrial oxidative phosphorylation predominately account for energy production in C-MSC ...

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]
, 2010 The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Learning by heart: cardiac cycle reveals an effective time window for learning.
Journal of Neurophysiology, 2018 Cardiac cycle phase is known to modulate processing of simple sensory information. This effect of the heartbeat on brain function is likely exerted via baroreceptors, the neurons sensitive for changes in blood pressure.
