The relationship of myocardial collagen metabolism and reverse remodeling after cardiac resynchronization therapy [PDF]

Journal of Medical Biochemistry, 2016
Background: In the majority of patients with a wide QRS complex and heart failure resistant to optimal medical therapy, cardiac resynchronization therapy (CRT) leads to reverse ventricular remodeling and possibly to changes in cardiac collagen synthesis ...

Entrainment of randomly coupled oscillator networks by a pacemaker [PDF]

, 2004
Entrainment by a pacemaker, representing an element with a higher frequency, is numerically investigated for several classes of random networks which consist of identical phase oscillators.

Leadless pacemaker implant in patients with pre‐existing infections: Results from the Micra postapproval registry

Cardiovascular Electrophysiology, 2019
Leadless pacemakers may provide a safe and attractive pacing option to patients with cardiac implantable electronic device (CIED) infection. We describe the characteristics and outcomes of patients with a recent CIED infection undergoing Micra implant ...

Splice variants of DOMINO control Drosophila circadian behavior and pacemaker neuron maintenance. [PDF]

, 2019
Circadian clocks control daily rhythms in behavior and physiology. In Drosophila, the small ventral lateral neurons (sLNvs) expressing PIGMENT DISPERSING FACTOR (PDF) are the master pacemaker neurons generating locomotor rhythms.

Downregulated lncRNA RCPCD promotes differentiation of embryonic stem cells into cardiac pacemaker-like cells by suppressing HCN4 promoter methylation

Cell Death and Disease, 2021
Long non-coding RNA (lncRNA) is receiving increasing attention in embryonic stem cells (ESCs) research. However, the roles of lncRNA in the differentiation of ESCs into pacemaker-like cells are still unclear.

Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Left bundle branch area pacing optimized cardiac resynchronization – a promise of way better?

Cardiologia Hungarica
Conduction system pacing may revolutionize conventional pacemaker therapy. Both His- and left bundle branch area pacing (LBBAP) can prevent right ventricular pacing induced cardiomyopathy in bradycardia pacemaker indications, furtheron they might improve

Cardiac Pacemaker Activity and Aging.

Annual Review of Physiology, 2019
A progressive decline in maximum heart rate (mHR) is a fundamental aspect of aging in humans and other mammals. This decrease in mHR is independent of gender, fitness, and lifestyle, affecting in equal measure women and men, athletes and couch potatoes ...

Portable Low‐Field Magnetic Resonance Imaging in People With Human Immunodeficiency Virus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The aging population of people with HIV (PWH) raises heightened concerns regarding accelerated aging and dementia. Portable, low‐field MRI (LF‐MRI) is an innovative technology that could enhance access and facilitate routine monitoring of PWH.
