Over expression of Plk1 does not induce cell division in rat cardiac myocytes in vitro. [PDF]

PLoS ONE, 2009
BackgroundMammalian 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 ...

Improving visualization of 4D flow cardiovascular magnetic resonance with four-dimensional angiographic data: generation of a 4D phase-contrast magnetic resonance CardioAngiography (4D PC-MRCA)

Journal of Cardiovascular Magnetic Resonance, 2017
Magnetic Resonance Angiography (MRA) and Phase-Contrast MRA (PC-MRA) approaches used for assessment of cardiovascular morphology typically result in data containing information from the entire cardiac cycle combined into one 2D or 3D image.

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.

Never in mitosis gene A related kinase-6 attenuates pressure overload-induced activation of the protein kinase B pathway and cardiac hypertrophy.

PLoS ONE, 2014
Cardiac hypertrophy appears to be a specialized form of cellular growth that involves the proliferation control and cell cycle regulation. NIMA (never in mitosis, gene A)-related kinase-6 (Nek6) is a cell cycle regulatory gene that could induce centriole

Electrokymographic Studies of the Normal Cardiac Cycle [PDF]

Circulation, 1950
Normal subjects were studied by employing two electrokymograms simultaneously. By comparing the sequence of events in the carotid pulse, auricle and ventricle, measurements were made of the phases of the cardiac cycle. The normal electrokymogram is discussed and illustrated.

Tricuspid annulus: A spatial and temporal analysis

Annals of Cardiac Anaesthesia, 2016
Background: Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension.

UCP2 modulates cardiomyocyte cell cycle activity, acetyl-CoA, and histone acetylation in response to moderate hypoxia

JCI Insight, 2022
Developmental cardiac tissue is regenerative while operating under low oxygen. After birth, ambient oxygen is associated with cardiomyocyte cell cycle exit and regeneration. Likewise, cardiac metabolism undergoes a shift with cardiac maturation.

Left Ventricular Entropy as a Measure of Wall Motion Abnormalities in Echocardiography Images [PDF]

Iranian Journal of Electrical and Electronic Engineering
Cardiovascular diseases (CVD) are today a major cause of death globally that is diagnosed by measurement and quantification of left ventricle (LV) wall motion (WM) abnormality of the heart.

Distinct effects of inflammation on preconditioning and regeneration of the adult zebrafish heart [PDF]

Open Biology, 2016
The adult heart is able to activate cardioprotective programmes and modifies its architecture in response to physiological or pathological changes. While mammalian cardiac remodelling often involves hypertrophic expansion, the adult zebrafish heart ...
