4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function

The Journal of Physiology, EarlyView.
Abstract figure legend Atrial fibrillation commonly develops in the left atrium and pulmonary veins (PVs), and can be triggered by sympathetic nerve activity. Here, we examined regional atrial differences in sympathetic nerve distribution and function in the rat.

Myocardial stretch‐induced ROS production is enhanced prior to the development of heart failure under TAC‐induced pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend To elucidate the relationship between oxidative stress in heart failure induced by chronic mechanical overload and physiological NOX2‐derived stretch‐induced reactive oxygen species (ROS) that support myocardial contractility during acute stretch, we investigated the changes in stretch‐induced ROS following transverse aortic ...

Therapeutic Balloon‐Assisted Enteroscopy: Recent Advances in the Management of Small Bowel Diseases

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Balloon‐assisted enteroscopy (BAE) has substantially advanced small bowel disease management. This review summarizes recent therapeutic BAE advances, focusing on three major indications: small bowel vascular lesions, hereditary polyposis syndromes, and Crohn's disease (CD).

Correlating Pulmonary Hemodynamics With HP 129Xe Dissolved‐Phase MRSI in a Controlled Porcine Intervention Study

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2588-2600, December 2026.
ABSTRACT Purpose Pulmonary hypertension is related to a 1‐year mortality ranging from < 5% to > 20% in low‐ and high‐risk groups. Right heart catheterization is the diagnostic gold standard, associated with a 1.1% rate of severe adverse events, posing the need for a non‐invasive diagnostic tool.

An Ascorbic‐Acid Containing Poly(Carbonate) Urethane With Antioxidant Bioactivity for Application in Heart Valve Scaffold Development

Journal of Biomedical Materials Research Part A, Volume 114, Issue 11, November 2026.
ABSTRACT Prosthetic heart valve development consists of several branching, innovative strategies to mediate the complex native environment that wears down valve durability. Anti‐calcification treatments are being applied to pericardial tissue, durable polymers are being developed that mitigate oxidative degradation and stress cracking, and heart valve ...
