Mechanisms of the “No-Reflow” Phenomenon After Acute Myocardial Infarction

JACC: Basic to Translational Science, 2023
Summary: Pericytes contract during myocardial ischemia resulting in capillary constriction and no reflow. Reversing pericyte contraction pharmacologically reduces no reflow and infarct size. These findings open up an entire new venue of research aimed at

Effects of anesthesia on conventional and speckle tracking echocardiographic parameters in a mouse model of pressure overload [PDF]

, 2015
Genetically‑modified mice are widely applied in cardiovascular studies as model organisms. Echocardiography is a key tool for evaluating cardiac and hemodynamic functions in mice.

The ezrin Gene Regulates Early Cardiac Morphogenesis and Contractile Function in Zebrafish Through the Coordinated Regulation of Apoptosis, Calcium Homeostasis, and the MAPK Signaling Pathway

Cells
Ezrin, expressed by the EZR gene, is a member of the ERM protein family that connects the plasma membrane to the actin cytoskeleton, participating in processes such as cell adhesion, migration, and signaling.

Effects of sugammadex and rocuronium on electro-mechanical activity of cardiac myocytes [PDF]

Korean Journal of Anesthesiology
Background Sugammadex reverses the effects of steroidal neuromuscular-blocking agents, such as rocuronium, by encapsulating these agents. Its cardiovascular adverse effects include QTc prolongation, hypotension, bradycardia, atrioventricular block ...

Effect of αα₂-adrenoceptor stimulation on the isolated rat heart after acute myocardial infarction

КардиоСоматика
Background: α2-Adrenoceptors (α2-ARs) are a family of G protein–coupled receptors. They are located on presynaptic membranes of adrenergic fibers, postsynaptic membranes of cardiomyocytes and vascular smooth muscle cells, as well as in the peripheral and

Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue [PDF]

, 2010
Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Myocardial contraction-relaxation coupling

American Journal of Physiology-Heart and Circulatory Physiology, 2010
Since the pioneering work of Henry Pickering Bowditch in the late 1800s to early 1900s, cardiac muscle contraction has remained an intensely studied topic for several reasons. The heart is located centrally in our body, and its pumping motion demands the attention of the observer.

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey

Arthritis Care &Research, EarlyView.
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...
