P2X7 receptors promote atrial remodeling and atrial fibrillation susceptibility via reactive oxygen species‐mediated mitogen‐activated protein kinase signaling activation

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Abstract Atrial fibrillation (AF), the most common clinical arrhythmia, is driven by inflammatory activation and oxidative stress, though precise molecular links remain unclear. This study identifies the P2X7 receptor as a key upstream regulator orchestrating proarrhythmic atrial remodeling through reactive oxygen species (ROS)‐mediated mitogen ...

Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

Simultaneous Multi‐Slice Acceleration for Free‐Breathing Motion Corrected Late Gadolinium Enhancement Imaging

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3333-3340, June 2026.
ABSTRACT Purpose The objective of this study was to develop and evaluate an accelerated free‐breathing motion corrected and averaged late gadolinium enhancement MRI (FB PSIR‐MoCo LGE) protocols. Methods Simultaneous multi‐slice (SMS) bSSFP imaging with GC‐LOLA correction and a multiband factor of two was implemented into a FB PSIR‐MoCo LGE sequence ...

K‐CC‐MoCo: A Fast k‐Space‐Based Respiratory Motion Correction for Highly Accelerated First‐Pass Perfusion Cardiovascular MR

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3536-3549, June 2026.
ABSTRACT Purpose First‐pass perfusion cardiovascular MR (FPP‐CMR) enables the non‐invasive diagnosis of microcirculation and coronary artery disease. In free‐breathing FPP‐CMR, motion correction is usually performed in the image domain, requiring an initial reconstruction.

Free‐Running Three‐Dimensional Cardiac Extracellular Volume Mapping in a Single Scan With Mid‐Scan Contrast Injection

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3360-3368, June 2026.
ABSTRACT Purpose To develop a new method for free‐running three‐dimensional (3D) extracellular volume mapping of the heart in a single scan with mid‐scan contrast injection. Methods 3D cardiac MR imaging was performed with a single scan that acquired k‐space data continuously using an inversion recovery (IR) sequence with a spoiled gradient‐echo ...
