A concise review on the anatomy of the atrioventricular node in mammals [PDF]

open access: yesThe Iranian Journal of Veterinary Science and Technology, 2009
Cardiac conduction system enables the heart to pulsate continuously by producing electric impulse and conducting it. As the anatomical information about cardiac conduction system in human being and other mammals needed in various fields of sciences, such

Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

open access: yesFEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

Cardiac Arrhythmias In Congenital Heart Diseases

open access: yesIndian 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,

Revolutionizing cardiovascular medicine: targeted therapies for the cardiac conduction system

open access: yesThe Journal of Clinical Investigation, 2022
Arrhythmogenic cardiovascular disorders are associated with considerable morbidity and mortality. Whether cardiac conduction disease is caused by genetic defects, procedural perturbations, valvular disease, ischemia, aging, or heart failure, new ...

The cochaperone BAG3 promotes the stabilization of p53 under heat stress conditions

open access: yesFEBS Open Bio, EarlyView.
Under heat stress, BAG3 translocates to the nucleus and forms a complex with Hsp70 and p53, thereby promoting p53 stabilization and enhancing its transcriptional activity. These findings suggest that BAG3 functions as a cochaperone that supports p53‐mediated stress responses in cooperation with Hsp70.

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

open access: yesSão 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 ...

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

open access: yesFEBS 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 ...

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

open access: yesThe 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

open access: yesJournal 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.

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

open access: yesFEBS 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 ...
