The Value of Voltage Histogram Analysis Derived Right Atrial Scar Burden in the Prediction of Left Atrial Scar Burden

Cardiology Research and Practice, 2020
Introduction. Growing evidence suggests that fibrotic changes can be observed in atrial fibrillation (AF) in both atria. Quantification of the scar burden during electroanatomical mapping might have important therapeutic and prognostic consequences ...

Atrial fibrillation

Nature Reviews Disease Primers, 2022
Atrial fibrillation (AF) is the most common cardiac arrhythmia despite substantial efforts to understand the pathophysiology of the condition and develop improved treatments. Identifying the underlying causative mechanisms of AF in individual patients is difficult and the efficacy of current therapies is suboptimal. Consequently, the incidence of AF is

Quiescent Elongation of α-Synuclein Pre-form Fibrils Under Different Solution Conditions

Frontiers in Neuroscience, 2022
The intracellular aggregation of α-synuclein in neurons/glia is considered to be a key step in the pathogenesis of synucleinopathy [including Parkinson’s disease (PD), dementia with Lewy body (DLB), multiple system atrophy (MSA), etc.].

Covid-19 pandemic induced traumatizing medical job contents and mental health distortions of physicians working in private practices and in hospitals

Scientific Reports, 2023
The Covid-19 pandemic during its early phases posed significant psychological threats particularly for medical frontline personal. It is unclear whether the medical workforce with the passage of time has adapted to these threats or have generalized to ...

Long-term results of ablation index guided atrial fibrillation ablation: insights after 5+ years of follow-up from the MPH AF Ablation Registry

Frontiers in Cardiovascular Medicine
BackgroundCatheter ablation (CA) for symptomatic atrial fibrillation (AF) offers the best outcomes for patients. Despite the benefits of CA, a significant proportion of patients suffer a recurrence; hence, there is scope to potentially improve outcomes ...

Characteristics of Cellulose Nanofibrils from Transgenic Trees with Reduced Expression of Cellulose Synthase Interacting 1

Nanomaterials, 2022
Cellulose nanofibrils can be derived from the native load-bearing cellulose microfibrils in wood. These microfibrils are synthesized by a cellulose synthase enzyme complex that resides in the plasma membrane of developing wood cells.

The safety of direct transeptal puncture using a radiofrequency guidewire combined with a 17Fr pulsed field ablation sheath

Scientific Reports
Transseptal puncture (TSP) is widely used in catheter-based cardiac interventions to gain left atrial (LA) access, but its workflow has remained largely unchanged and is still a source of serious complications.

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

FEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.
