GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

open access: yesThe FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Zero‐Contrast Versus Contrast‐Guided Left Atrial Appendage Occlusion: A Comparative Analysis of Procedural and Long‐Term Outcomes

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Zero‐contrast left atrial appendage occlusion yielded high procedural success and similar periprocedural adverse event rates compared to the contrast‐guided approach. At 45‐day follow‐up, successful LAA closure (defined as peri‐device leak ≤ 5 mm) and device‐related thrombus rates were similar.

Intracardiac Echocardiography and Coronary Angiography During Ventricular Ablation From the Aortic Cusps and Commissures: Marked Inter‐Center Variability Without an Observed Coronary Injury Signal

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Catheter ablation of premature ventricular complexes (PVCs) and ventricular tachycardia (VT) arising from the aortic cusps and commissures is effective but performed near the coronary ostia, raising concern for coronary injury. Adjunct imaging with intracardiac echocardiography (ICE) and coronary angiography is variably used, and ...

PVC Variability and Impact on Meeting Expert Consensus Cutoffs of ≥ 10 000 PVCs/Day and ≥ 15% PVCs

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
14‐day Zio® (iRhythm) datasets of 606 patients between December 2018 and January 2019 who had at least one day of ≥10,000 PVCs were acquired. Of these patients, a subcohort of 325 patients who had at least one day of ≥15% PVCs was generated. In both groups, analyses were carried out showing that longer duration monitoring increased sensitivity for ...

Long‐Term Serial Exercise Stress Testing in Catecholaminergic Polymorphic Ventricular Tachycardia on Beta‐Blocker and Flecainide Therapy

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially life‐threatening arrhythmic disorder typically treated with beta‐blockers and, occasionally, with flecainide. Methods All patients underwent genetic testing, electrocardiogram, echocardiogram, and exercise testing.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Stem Cells From Dental Pulp, Periodontal Tissues, and Other Oral Sources: Biological Concepts and Regenerative Potential

open access: yesJournal of Periodontal Research, EarlyView.
A graphical abstract recapping the different sources of dental, periodontal, and other oral‐derived mesenchymal stromal cells (MSCs) and their regenerative mechanisms and potentials. The review's article findings bridge fundamental biological science with translational advances, highlighting the significance of MSCs in craniofacial regenerative ...
