Early experience with permanent pacemaker implantation at a tertiary hospital in Nigeria
The Pan African Medical Journal, 2020 INTRODUCTION: Artificial pacemakers generate electrical impulses and regulate the heart´s conduction system. They are often used to treat individuals with bradycardia. Permanent pacemaker implantation is a lifesaving procedure especially in patients with

Troubleshooting During Temporary Epicardial Lead Implantation in a Child with an Erosive Twiddler’s Syndrome and Multiple Sternotomies: A case report [PDF]
, 2023 Temporary epicardial cardiac pacing in patients with bradyarrhythmias may be used as a bridge to implantation of a permanent pacemaker. The temporary epicardial lead placement may sometimes necessitate a sternotomy that may pose a challenge in patients ...

Experimental analysis and computational modeling of interburst intervals in spontaneous activity of cortical neuronal culture [PDF]
, 2011 Rhythmic bursting is the most striking behavior of cultured cortical networks and may start in the second week after plating. In this study, we focus on the intervals between spontaneously occurring bursts, and compare experimentally recorded values with

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.
