Incidence of New Onset Atrial Fibrillation After Cardiovascular Surgery in Vietnam: Results From A Novel Screening Strategy.

Objective: To examine the incidence of atrial fibrillation (AF) newly developed after cardiovascular surgery in Vietnam, its associated risk factors, and postoperative complications. We also sought to evaluate the feasibility of a novel screening strategy for post-operative AF (POAF) using the combination of two portable devices.

Methods: Single-centre, prospective cohort study at the Cardiovascular Centre, E Hospital, Hanoi, Vietnam.

A Generalizable Platform for the Photoactivation of Cell Surface Receptors.

Polarized signal transduction from cell surface receptors plays a central role in the development and homeostasis of multicellular organisms, and it also contributes to cellular dysfunction in many disease states. Understanding the molecular and cellular bases of polarized signaling requires experimental methods that provide precise spatiotemporal control of receptor activation. However, we currently lack strategies for inducing both sustained and spatially constrained signal transduction.
