Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

FEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

Complete atrioventricular block during renal transplantation in a patient with Alport's syndrome: case report

São Paulo Medical Journal, 2001
CONTEXT: Patients with Alport's syndrome (causing 5% of end-stage renal disease) have a higher risk of heart conduction abnormalities. OBJECTIVE: To report a case of Alport's syndrome developing complete atrioventricular block during renal ...

Influence of Atrioventricular Nodal Reentrant Tachycardia Ablation on Right to Left Inter-atrial Conduction [PDF]

, 2005
Background: Radiofrequency (RF) catheter ablation is the procedure of choice for the potential cure of atrioventricular nodal reentrant tachycardia (AVNRT) with high success rates.

Modeling the Heart as a Communication System [PDF]

, 2014
Electrical communication between cardiomyocytes can be perturbed during arrhythmia, but these perturbations are not captured by conventional electrocardiographic metrics.

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

FEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

Cardiac Arrhythmias In Congenital Heart Diseases

Indian Pacing and Electrophysiology Journal, 2009
Arrhythmias figure prominently among the complications encountered in the varied and diverse population of patients with congenital heart disease, and are the leading cause of morbidity and mortality. The incidence generally increases as the patient ages,

Development of the Cardiac Conduction System and the Possible Relation to Predilection Sites of Arrhythmogenesis

The Scientific World Journal, 2008
The cardiac conduction system (CCS) encompasses a complex system responsible for the coordinated contraction of the heart. In the developing heart, as well as in the adult heart, tissues of the (putative) CCS are characterized by different properties ...

Evolution of the Sinus Venosus from Fish to Human

Journal of Cardiovascular Development and Disease, 2014
The sinus venosus, the cardiac chamber upstream of the (right) atrium, is a severely underinvestigated structure. Yet, its myocardium harbors the cardiac pacemaker in all vertebrates.

T-box transcription factor 3 governs a transcriptional program for the function of the mouse atrioventricular conduction system

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Genome-wide association studies have identified common noncoding variants associated with ECG parameters in the TBX3 locus, suggesting that a modest change in TBX3/Tbx3 expression level affects heart function. We characterized the morphology,

Electrical pulse stimulation reflecting the episodic nature of real‐life exercise modulates metabolic and secretory profile of primary human myotubes

FEBS Open Bio, EarlyView.
Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.
