Prognostic Impact of Spontaneous Conversion to Sinus Rhythm in Patients With Symptomatic Paroxysmal Atrial Fibrillation: A Propensity‐Matched Follow‐Up Study [PDF]

open access: yesJournal of Cardiovascular Electrophysiology, Volume 36, Issue 12, Page 3222-3230, December 2025.
ABSTRACT Background Paroxysmal atrial fibrillation (PAF) patients do not invariably progress to persistent AF, with a consistent group of patients showing AF regression during follow‐up. The prognostic implications of spontaneous conversion (SCV) to sinus rhythm (SR) in those patients has never been evaluated yet.

Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison

open access: yesMacromolecular Materials and Engineering, Volume 308, Issue 1, January 2023., 2023
Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...
