Comparative Efficacy and Safety of Cryoballoon vs Laser Balloon Ablation for Pulmonary Vein Isolation in Patients With Paroxysmal Atrial Fibrillation

Journal of Patient-Centered Research and Reviews
Purpose: Atrial fibrillation (AF), the most common arrhythmia in older adults, is often treated with cryoballoon ablation (CBA) or laser balloon ablation (LBA) when refractory to medication.

Silicon clusters produced by femtosecond laser ablation: Non-thermal emission and gas-phase condensation

, 2004
Neutral silicon clusters Si_n (up to n = 7) and their cations Si_n+ (up to n = 10) have been produced by femtosecond laser ablation of bulk silicon in vacuum and investigated using time-of-flight mass spectrometry.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

(Ti,Zr,Hf,Ta)CN/SiCN: A new ultrahigh-temperature ceramic nanocomposite with excellent mechanical properties and ablation resistance

Journal of Advanced Ceramics
Dense monolithic (Ti,Zr,Hf,Ta)CN/SiCN ceramic nanocomposites are prepared via the pyrolysis of novel (Ti-,Zr-,Hf-,Ta)-containing single-source precursors (SSPs) and spark plasma sintering (SPS) with a high heating rate.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Epicardial Electrical Activation During Atrial Fibrillation

JACC: Case Reports, 2019
High-definition mapping of atrial fibrillation is most commonly performed from the endocardial surface. This report describes an example of a case in which combined mapping of the endocardium and epicardium of the left atrium demonstrated electrical ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
