Lesion Formation in Cardiac Pulsed‐Field Ablation: Acute to Chronic Cellular Level Changes

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT As pulsed‐field ablation (PFA) emerges as a promising therapy for atrial arrhythmias, an understanding of the cellular injury to cardiac tissue is critical to evaluating and interpreting results for each PFA system. This review aims to detail the mechanism of cell death for PFA, compare the cell death mechanism to thermal ablation modalities ...

Role of Autonomic Dysfunction in Initiating Postoperative Atrial Fibrillation in a Canine Sterile Pericarditis Model

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Autonomic dysfunction plays a significant role in initiating postoperative atrial fibrillation (POAF) by causing atrial ectopic triggers, potentially through mechanisms such as increased sympathetic activity and altered vagal tone.

Saline‐based modified del Nido cardioplegia versus multidose St. Thomas cardioplegia in canine mitral valve repair: A randomized controlled trial

Veterinary Surgery, EarlyView.
Abstract Objective To compare the utility of a saline‐based modified del Nido (mDN) cardioplegia solution with a conventional institutional technique (multidose St. Thomas blood cardioplegia) for mitral valve repair (MVR) in dogs. Study design Prospective, randomized, open‐label trial.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Brown and beige adipose tissue‐derived metabokine and lipokine inter‐organ signalling in health and disease

Experimental Physiology, EarlyView.
Abstract Adipose tissue has an established endocrine function through the secretion of adipokines. However, a role for bioactive metabolites and lipids, termed metabokines and lipokines, is emerging in adipose tissue‐mediated autocrine, paracrine and endocrine signalling and inter‐organ communication. Traditionally seen as passive entities, metabolites
