Pulmonary vein isolation and the Cox maze procedure only partially denervate the atrium [PDF]

open access: yes, 2008
ObjectivesThe effects of ablation lines on myocardial innervation and response to autonomic stimuli are unclear. This study examined the effects of radiofrequency ablation on atrial autonomic innervation and compared pulmonary vein isolation and the ...

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

An Optimized Freeze‐Dry Multimodal Workflow for Sequential Micro‐CT Imaging, Histology, and Molecular Profiling: A Use Case in Human Liver Fibrosis

open access: yesAdvanced Science, EarlyView.
Optimized freeze‐drying and eosin staining deliver artifact‐free micro‐CT images of liver tissue at near‐histological detail, then hand the same specimen back for sectioning, staining, and sequencing. Fibrotic volume distinguishes normal liver from cirrhosis, while preserved RNA reveals inflammatory gene upregulation—one biopsy, three dimensions, and a

Mesenchymal Stromal Cell‐Based Cell–Drug Conjugates for the Treatment of Acute Liver Failure

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cell (MSC)‐based cell‐drug conjugates are constructed by anchoring rosiglitazone‐loaded nanoparticles onto the MSC surface. Sustained rosiglitazone release enhances MSC proliferation and paracrine activity while promoting anti‐inflammatory macrophage polarization.

Catheter pulmonary vein isolation with drug testing of dormant conduction and detection of non-pulmonary vein triggers and high frequency stimulation of left atrial ganglionated plexi in patients with paroxysmal atrial fibrillation

open access: yesПатология кровообращения и кардиохирургия, 2018
Background. Catheter pulmonary vein isolation (PVI) is the main interventional procedure for treatment of atrial fibrillation (AF). Recurrences of arrhythmia paroxysms in the postoperative period are mainly determined by reconnection of conduction from ...

Paroxysmal atrial fibrillation ablation: Achieving permanent pulmonary vein isolation by point-by-point radiofrequency lesions

open access: yes, 2017
Pulmonary vein isolation by point-by-point radiofrequency catheter ablation constitutes the cornerstone of catheter ablation strategies for the treatment of atrial fibrillation.

The Adipose‐Sympathetic Nerve Crosstalk: FSTL1 as an Adipocyte‐Derived Neurotrophic Factor for WAT Browning

open access: yesAdvanced Science, EarlyView.
As a novel adipose‐derived neurotrophic factor, Follistatin‐like 1 is endocytosed by sympathetic neurons primarily via tropomyosin‐related kinase B. This process promotes sympathetic innervation in adipose tissue and norepinephrine release, leading to white adipose tissue browning, enhanced thermogenesis, and anti‐obesity effects in mice.

Influence of pulmonary vein isolation on respiratory sinus arrhythmia in patients with paroxysmal atrial fibrillation

open access: yes, 2018
Die Respiratorische Sinusarrhythmie (RSA) beschreibt die Synchronisation von Herzfrequenzvariation und Atmung. Maßgeblich bestimmt durch die phasische Ruheaktivität des parasympathischen Nervensystems, ist die RSA an der Optimierung der kardiopulmonalen

OAF Blocks SIAH1‐Mediated Degradation of SCPX, a Therapeutic Strategy for MASLD

open access: yesAdvanced Science, EarlyView.
This study shows OAF directly binds to SCPX and inhibits its interaction with the E3 ligase SIAH1, thereby protecting SCPX from ubiquitin‐dependent degradation and stabilizing its levels. This OAF‐SCPX axis represents a novel pathway in lipid homeostasis, highlighting OAF as a promising therapeutic candidate for MASLD.

Natural Product Toosendanin Suppresses the Malignant Development of Skin Melanoma by Targeting BNC2 for Degradation

open access: yesAdvanced Science, EarlyView.
BNC2 exhibits context‐dependent opposing functions across multiple cancer types. This study reveals BNC2 as an oncogenic driver of melanoma proliferation and metastasis through transcriptional activation of PIK3CA. The natural compound TSN simultaneously degrades BNC2 and its oncogenic partner SMAD3 via CRBN‐dependent ubiquitination.
