Hand2 Is an Essential Regulator for Two Notch-Dependent Functions within the Embryonic Endocardium

Cell Reports, 2014
The basic-helix-loop-helix (bHLH) transcription factor Hand2 plays critical roles during cardiac morphogenesis via expression and function within myocardial, neural crest, and epicardial cell populations.

Directional X‐Ray Scattering and Microtomography for Laboratory‐Based Imaging of Fibrous Materials and Biological Tissues

Small Science, Volume 6, Issue 8, August 2026.
A compact laboratory X‐ray system enables directional dark‐field imaging and tomography with sensitivity to scattering along two orthogonal directions. The approach provides volumetric mapping of sub‐resolution microstructure in engineering and biological samples, which reveals structural heterogeneity, fiber organization, and anisotropic scattering ...

A left ventricular wall segmentation method for cardiac magnetic resonance image

四川大学学报. 自然科学版, 2016
Segmenting endocardium and epicardium of left ventricle from cardiac magnetic resonance image (cardiac MRI), is the prerequisites for three-dimensional reconstruction of heart and cardiac function assessment.

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...

Effect of myocardial heterogeneity on ventricular electro-mechanical responses: a computational study

BioMedical Engineering OnLine, 2019
Background The heart wall exhibits three layers of different thicknesses: the outer epicardium, mid-myocardium, and inner endocardium. Among these layers, the mid-myocardium is typically the thickest.

Air embolism secondary to suspected lymphatic tissue disruption with severe exercise‐induced pulmonary haemorrhage

Equine Veterinary Education, Volume 38, Issue 8, Page e501-e508, August 2026.
Summary Air embolism is rare in horses and typically associated with complications following intravenous catheterisation or other medical procedures. Exercise‐induced pulmonary haemorrhage (EIPH) is common in racehorses but not usually associated with air embolism. This report describes a case of air embolism in a 4‐year‐old Thoroughbred with EIPH. The

Modified Anatomical Ablation Strategy for Mitral Isthmus

Pacing and Clinical Electrophysiology, Volume 49, Issue 8, Page 1159-1167, August 2026.
ABSTRACT Background Durable mitral isthmus (MI) block remains challenging in persistent atrial fibrillation (AF) ablation. Ethanol infusion into the vein of Marshall (EI‐VOM) enhances efficacy, but the minimal endocardial ablation extent post‐EI‐VOM is undefined.

Mesoscopic anatomy and histotopography of the left atrial appendage walls in human fetal heart

Сибирский научный медицинский журнал
Normal anatomy of the left atrial appendage (LAA) of human fetus is of a great importance for fetal cardiac surgery and heart bioprinting. Aim of the study was to clarify the mesoscopic anatomy and histotopography of different parts of the LAA walls in ...

Biomechanical signaling within the developing zebrafish heart attunes endocardial growth to myocardial chamber dimensions

Nature Communications, 2019
It is unknown how endocardium growth is coordinated with that of the myocardium in the zebrafish. Here, the authors show that myocardial chamber volume expansion causes increased endocardial tissue tension, which in turn triggers Hippo signaling-mediated

Ectopic Noggin in a Population of Nfatc1 Lineage Endocardial Progenitors Induces Embryonic Lethality

Journal of Cardiovascular Development and Disease, 2014
The initial heart is composed of a myocardial tube lined by endocardial cells. The TGFβ superfamily is known to play an important role, as BMPs from the myocardium signal to the overlying endocardium to create an environment for EMT.
