Exploring Cellular Dynamics in the Goldfish Bulbus Arteriosus: A Multifaceted Perspective

open access: yesFishes
The bulbus arteriosus of goldfish, Carassius auratus, possesses unique structural features. The wall of the bulbus arteriosus is exceptionally thick, with an inner surface characterized by longitudinally arranged finger-like ridges, resulting in an ...

Cardiac fibroelastosis associated with thromboembolism and paresis in a cat - Case report

open access: yesBrazilian Journal of Veterinary Pathology, 2019
A two-year-old, male, non-castrated cat was referred to the veterinary hospital with a three-month history of paresis of the pelvic limbs. Clinical examination revealed a discreet muffling of cardiac sounds and the presence of a degree III/VI ...

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Efficacy of Fixed Low‐Power Long‐Duration Radiofrequency Ablation of Ventricular Arrhythmias Originating From the Left Ventricular Summit

open access: yesJournal of Arrhythmia, Volume 42, Issue 3, June 2026.
Efficacy and safety of a fixed low‐power, long‐duration radiofrequency catheter ablation of ventricular arrhythmias originating from the left ventricular summit. ABSTRACT Background Radiofrequency catheter ablation (RFCA) of ventricular arrhythmias originating from the left ventricular summit (LVS‐VAs) remains challenging.

Characterization of Inflammation in In Vivo Mouse Myocardium Using Longitudinal Rotating Frame Relaxation Time (T1ρ) and T2 Relaxation Time Maps

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
Acute and chronic inflammatory area in mouse myocardium can be associated with increased CW‐T1ρ and T2 after intramyocardial adenoviral injection. Inflammation reaction can be followed up with these endogenous relaxation time constant biomarkers. ABSTRACT Cardiac magnetic resonance imaging (MRI) is a gold standard to assess functional and anatomical ...

Early endocardial morphogenesis requires Scl/Tal1.

open access: yesPLoS 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,

Osborn Waves: History and Significance [PDF]

open access: yes, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

Teriparatide in Two Patients With Mucopolysaccharidosis Type IVB

open access: yesJIMD Reports, Volume 67, Issue 3, May 2026.
ABSTRACT Mucopolysaccharidosis Type IV is a multisystem lysosomal storage disease characterized by severe skeletal dysplasia resulting from impaired degradation of the glycosaminoglycans keratan sulfate and chondroitin‐6‐sulfate. The condition is classified into Types A and B based on the underlying enzyme deficiency.

A developmental model for the pathogenenesis of cardiac arterio-ventricular fistulae [PDF]

open access: yes, 2017
Coronary Artery Fistulae (CAF) are congenital coronary artery (CA) anomalies consisting of an abnormal communication of a coronary artery with either a cardiac chamber or a large cardiac vessel.

Plasma Dilution After Myocardial Ischemia–Reperfusion Injury Promotes Cardiac Repair, Heart Performance, and Recovery of Motor Function and Endurance in Old Mice

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Plasma dilution at 24 h after I/R improved cardiac remodeling, function, and the physical performance of old male and female mice, through lowered markers of inflammation, fibrosis, reduction of cardiomyocytes' apoptosis, increase in their cell‐cycle re‐entry, and healthier profile of newly synthesized proteome, including the determinants of Jak/Stat ...
