A microstructurally motivated framework to study autoregulation in the coronary circulation

The Journal of Physiology, EarlyView.
Abstract figure legend A microstructurally motivated framework was constructed to simulate coronary autoregulation in symmetrically bifurcating trees at three myocardial depths: subepicardial (subepi), midwall and subendocardial (subendo). Wall mechanics of individual vessels are governed by a constrained‐mixture model, incorporating elastin, collagen ...

Variable electrophysiology before and after block of the two delayed rectifier potassium channels in groups of isolated rabbit ventricular cells

British Journal of Pharmacology, Volume 183, Issue 13, Page 3685-3705, July 2026.
Abstract Background and Purpose Between‐cell differences in ventricular cardiomyocyte action potential duration (APD) and responses to ion channel block may contribute to pro‐arrhythmic dispersion of myocardial repolarisation. This study quantifies between‐cell physiological and pharmacological variability in the rabbit left ventricle (LV) and uses ...

Early endocardial morphogenesis requires Scl/Tal1.

PLoS Genetics, 2007
The primitive heart tube is composed of an outer myocardial and an inner endocardial layer that will give rise to the cardiac valves and septa. Specification and differentiation of these two cell layers are among the earliest events in heart development,

Unravelling the Genetic Mechanisms of Litter Traits in a Maternal Line of Pigs

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 560-580, July 2026.
ABSTRACT Reproductive traits related to litter size are the main indicators of reproductive efficiency in pig production and are continuously evaluated for the selection of maternal lines. Several environmental and genetic factors are involved with the development of these traits.

ERDHEIM‐Chester Disease: Two Fatal Cases With Unusual Presentations

Clinical Case Reports, Volume 14, Issue 6, June 2026.
Fluorodeoxyglucose positron emission tomography‐computed tomography (FDG PET‐CT) demonstrated markedly increased metabolic activity in serosal surfaces including pericardium, pleura, and renal fascia, as well as diffuse uptake along vascular walls, particularly the entire aorta.

Patient‐Specific In Silico Prediction of Outcomes of Partial Continuous‐Flow LVAD Treatment in Peripartum Cardiomyopathy

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
Partial continuous‐flow left ventricular assist device (LVAD) treatment of peripartum cardiomyopathy provides greater functional improvement for higher than lower disease severity. The left ventricle and LVAD jointly generate ventricular output for mild functional impairment, where the left ventricular contribution decreases with increasing LVAD ...

Pvr and Pvf2 Are Essential for Valve Cell Differentiation in the Larval Drosophila Heart

genesis, Volume 64, Issue 3, June 2026.
ABSTRACT The directionality of blood flow is regulated by heart valves, among other things. While the heart valves in vertebrates are multicellular and complex, the valve in the Drosophila heart consists of exactly two highly specialized cells. They arise during early larval development from two cardiomyocytes, those that form the boundary between the ...

Cervical cancer with patent foramen ovale metastasis to the left ventricle: a case report

World Journal of Surgical Oncology
Background Metastasis of malignant tumors to the cardiac endocardium is rare and mainly involves the right side of the heart. It is extremely rare to involve the left cardiac endocardium, especially when there is neither pulmonary metastasis nor primary ...
