The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

Animal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.

Complete atrioventricular block during neonatal intubation: a case report

Resuscitation Plus
Preterm infants often experience side effects from intubation. Desaturation and sinus bradycardia are frequent. Atropine as premedication mitigates these risks.We report the occurrence of severe bradycardia related to atrioventricular block during ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Suppression of Atrial Fibrillation Following Successful Ablation of Atrioventricular Nodal Reentrant Tachycardia: A Case Report

Kaohsiung Journal of Medical Sciences, 2009
Inducible atrioventricular nodal reentrant tachycardia was demonstrated by electrophysiological studies in a 55-year-old female who suffered from intermittent palpitation, in which paroxysmal atrial fibrillation (AF) was consistently documented by ...

Role of nitric oxide on the electrophysiological properties of isolated rabbit atrioventricular node by extracellular field potential during atrial fibrillation [PDF]

, 2011
Introduction: The aim of the present study was to determine direct effects of NO modulation on protective electrophysiological properties of atrioventricular node (AV node) in the experimental model of AF in rabbit.

Moving Domain Computational Fluid Dynamics to Interface with an Embryonic Model of Cardiac Morphogenesis [PDF]

, 2013
Peristaltic contraction of the embryonic heart tube produces time- and spatial-varying wall shear stress (WSS) and pressure gradients (∇P) across the atrioventricular (AV) canal.

Long‐Term Outcomes of Reduced Intensity Conditioning Hematopoietic Stem Cell Transplantation for Systemic Sclerosis Patients with Impaired Cardiac Function

Arthritis &Rheumatology, Accepted Article.
Objective High intensity conditioning autologous hematopoietic stem cell transplantation (AHSCT) is standard of care for patients with advanced SSc. The role of reduced intensity conditioning (RIC) prior to AHSCT in this population remains unclear. We conducted this study to determine the long‐term outcomes of RIC AHSCT in SSc patients with cardiac ...

A curious alliance: Sinus nodal dysfunction precipitating atrioventricular block

Journal of Arrhythmia, 2014
An elderly woman presented with recurrent syncope. Sinus bradycardia and sinoatrial block were seen on the electrocardiogram; however, PR interval prolongation after sinus pauses suggested atrioventricular conduction system disease.

Protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node of rabbit [PDF]

, 2011
Introduction: Recent studies have shown acute cardioprotective effects of cyclosporine. The aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using ...
