Cardiac fibroblasts regulate myocardium and coronary vasculature development in the murine heart via the collagen signaling pathway

eLife
The fibroblast (FB), cardiomyocyte (CM), and vascular endothelial cell (Vas_EC) are the three major cell types in the heart, yet their relationships during development are largely unexplored. To address this gap, we employed RNA staining of the FB marker

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Identification of the Ectopic Foci of Focal Atrial Tachycardia (FAT) by Using Electrocardiogram (ECG) Signal Analysis [PDF]

مجله علمی دانشگاه علوم پزشکی کردستان
Background and Aim: Cardiac electrophysiology study (EPS) is the study of the electrical system of the heart. One of the most common methods of treating cardiac arrhythmias is ablation.

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.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

(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.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

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 ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
