Effect of Contact Force on Pulsed Field Ablation Lesions in Porcine Cardiac Tissue. [PDF]
, 2023 BACKGROUND Contact force has been used to titrate lesion formation for radiofrequency ablation. Pulsed Field Ablation (PFA) is a field-based ablation technology for which limited evidence on the impact of contact force on lesion size is available ...

Myocardial electroporation — an alternative to thermal methods of atrial fibrillation treatment
Рациональная фармакотерапия в кардиологии, 2023 Atrial fibrillation is one of the most common cardiac arrhythmias. By all estimates, the number of patients with this arrhythmia will only increase. Currently, the main and most used methods for the treatment of atrial fibrillation are radiofrequency and

Feasibility Study on Atrial Fibrillation Ablation with Pulsed Field Ablation and concomitant Occlusion of the Left Atrial Appendage. [PDF]
BACKGROUND AND AIMS Atrial fibrillation (AF) ablation and left atrial appendage occlusion (LAAO) are increasingly performed as individual procedures. Pulsed field ablation (PFA) has significantly reduced procedure duration and may be advantageous for ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

First worldwide use of pulsed‐field ablation for ventricular tachycardia ablation via a retrograde approach [PDF]
, 2023 Introduction: We present the first worldwide use of pulsed‐field ablation (PFA) for ventricular tachycardia (VT) ablation via a retrograde approach. Methods: The patient had previously failed conventional ablation of an intramural circuit underneath the ...

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
