Characteristics of left atrial remodeling in patients with atrial fibrillation and hypertrophic cardiomyopathy in comparison to patients without hypertrophy

open access: yesScientific Reports, 2021
Atrial fibrillation (AF) leads to remodeling characterized by changes in both size and shape of the left atrium (LA). Here we aimed to study the effect of hypertrophic cardiomyopathy (HCM) on the pattern of LA remodeling in AF-patients. HCM-patients (n =

Safe electrophysiologic profile of dexmedetomidine in different experimental arrhythmia models

open access: yesScientific Reports, 2021
Previous studies suggest an impact of dexmedetomidine on cardiac electrophysiology. However, experimental data is sparse. Therefore, purpose of this study was to investigate the influence of dexmedetomidine on different experimental models of ...

Proteomic and functional analysis of HDL subclasses in humans and rats: a proof-of-concept study

open access: yesLipids in Health and Disease, 2023
Background The previous study investigated whether the functions of small, medium, and large high density lipoprotein (S/M/L-HDL) are correlated with protein changes in mice. Herein, the proteomic and functional analyses of high density lipoprotein (HDL)

Laser-assisted Cellular Electrophysiology Measurement System [PDF]

open access: yesIEEE Photonics Technology Letters, Vol 33, Issue 3, p. 163-166, 2021, 2020
Patch-clamp technique is the gold standard for cellular electrophysiological measurements, which is capable of measuring single ion transport events across the cell membrane. However, the measurement possesses significant complexity, and it requires a high level of expertise, while its experimental throughput is nevertheless considerably low.

Transient receptor potential canonical 6 knockdown ameliorated diabetic kidney disease by inhibiting nuclear factor of activated T cells 2 expression in glomerular mesangial cells

open access: yesRenal Failure, 2022
Purpose Glomerular mesangial cell (GMC) dysfunction plays a vital role in the pathogenesis of diabetic kidney disease (DKD). Transient receptor potential canonical 6 (TRPC6) has been demonstrated to be involved in the development of DKD.

A fast computational model for the electrophysiology of the whole human heart [PDF]

open access: yes, 2021
In this study we present a novel computational model for unprecedented simulations of the whole cardiac electrophysiology. According to the heterogeneous electrophysiologic properties of the heart, the whole cardiac geometry is decomposed into a set of coupled conductive media having different topology and electrical conductivities: (i) a network of ...

Comparison of Electrocardiographic Repolarization Patterns between Hypogonad Males and Normal Subjects

open access: yesAnnals of Noninvasive Electrocardiology, 2003
Background: There is a significant difference in repolarization on the surface ECG between men and women. The effect of testosterone on repolarization of myocardium may provide a basis for the physiological and pathophysiological importance of these ...

Lidocaine as an anti‐arrhythmic drug: Are there any indications left?

open access: yesClinical and Translational Science, 2023
Lidocaine is classified as a class Ib anti‐arrhythmic that blocks voltage‐ and pH‐dependent sodium channels. It exhibits well investigated anti‐arrhythmic effects and has been the anti‐arrhythmic of choice for the treatment of ventricular arrhythmias for
