Microscopic and ultramicroscopic characteristic of heart valves in human [PDF]

Морфологія, 2014
Background. Valvular apparatus of the heart is the frequent object of the surgical operations for today. Morphological changes which are happed within valves of the heart at time of cardiac diseases the modern medicine considers on the clinical ...

Haemogenic endocardium contributes to transient definitive haematopoiesis. [PDF]

, 2013
Haematopoietic cells arise from spatiotemporally restricted domains in the developing embryo. Although studies of non-mammalian animal and in vitro embryonic stem cell models suggest a close relationship among cardiac, endocardial and haematopoietic ...

Peculiarities of macro- and cytometric assessment of morphological structures of the domestic pig heart

Regulatory Mechanisms in Biosystems
The cardiovascular system, which includes the heart, is one of the essential systems of the human and animal body. With its participation, the blood supply of the organs takes place; it promotes the outflow of lymph from the organs and its transport into

A Case of Coumadin Ridge Confirmed by Surgery: Comparison between Cardiac Computed Tomographic Images and Operative Findings

대한영상의학회지, 2019
The coumadin ridge, a ridge of atrial tissue separating the left atrial appendage from the left upper pulmonary vein, is considered to be a normal anatomic variant. A prominent coumadin ridge can be easily mistaken for a tumor or thrombus.

Three‐dimensional Integrated Functional, Structural, and Computational Mapping to Define the Structural “Fingerprints” of Heart‐Specific Atrial Fibrillation Drivers in Human Heart Ex Vivo

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundStructural remodeling of human atria plays a key role in sustaining atrial fibrillation (AF), but insufficient quantitative analysis of human atrial structure impedes the treatment of AF.

Effect of Alpha-Lipoic Acid on Rat Ventricles and Atria under LPS-Induced Oxidative Stress

Antioxidants, 2022
Alpha-lipoic acid (α-LA) is a disulfide compound and one of the most effective antioxidants. Many studies have indicated positive effects of α-LA in the prevention of pathologic conditions mediated by oxidative stress, such as cardiovascular diseases ...

Developmental expression of a functional TASK-1 2P domain K⁺ channel in embryonic chick heart

Journal of Biomedical Science, 2009
Background Background K+ channels are the principal determinants of the resting membrane potential (RMP) in cardiac myocytes and thus, influence the magnitude and time course of the action potential (AP). Methods RT-PCR and in situ hybridization are used

Anti-adrenergic effects of endothelin on human atrial action potentials are potentially anti-arrhythmic [PDF]

, 2006
Endothelin-1 (ET-1) is elevated in patients with atrial fibrillation (AF) and heart failure. We investigated effects of ET-1 on human atrial cellular electrophysiological measurements expected to influence the genesis and maintenance of AF.

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Transcriptomic uniqueness and commonality of the ion channels and transporters in the four heart chambers

Scientific Reports, 2021
Myocardium transcriptomes of left and right atria and ventricles from four adult male C57Bl/6j mice were profiled with Agilent microarrays to identify the differences responsible for the distinct functional roles of the four heart chambers.
