The Pathogenic Roles of Local Vitamin D Metabolism Defect in Valve Inflammation and Calcification

Advanced Science, EarlyView.
This study identifies the valvular interstitial cell populations responsible for valvular calcification induced by hyperphosphatemia and likely aging, uncovers local vitamin D metabolism defect‐induced inflammation as a critical pathogenic factor of calcific aortic valve disease, and highlights active vitamin D and ERK inhibitor as potential preventive

Follow-Up Report of Patients With Moderate Aortic Valve Regurgitation After Cardiac Surgery [PDF]

Texas Heart Institute Journal
Background: The appropriateness of aortic valve surgery for patients with moderate aortic valve regurgitation undergoing coronary artery bypass graft (CABG), mitral valve replacement (MVR), or both is uncertain.

Endothelial BMP6 Drives Hemodynamic‐Dependent VSMCs Calcification in Carotid Atherosclerosis

Advanced Science, EarlyView.
The study demonstrates that endothelial cell (EC)‐derived BMP6 promotes the osteogenic differentiation of vascular smooth muscle cells (VSMCs) through cell‐cell interactions. Additionally, the researchers preliminarily explore the driving effect of hemodynamic factors on BMP6‐induced calcification and reveal the regulatory role of KLF4 on BMP6.

Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

Advanced Science, EarlyView.
This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Quadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis

The Turkish Journal of Pediatrics, 2008
Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy.

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

Advanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Leucine‐Dependent SLC7A5–PGAM5 Interaction Promotes Advanced Atherosclerosis Through Hindering Mitochondrial Function of Macrophages

Advanced Science, EarlyView.
Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,

Single coronary ostium in a patient with quadricuspid aortic valve combined with aneurysmal ascending aortic dilatation

Journal of Cardiothoracic Surgery, 2017
Background The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures.

Mortality Patterns and Phenotypic Clusters in Trisomy 13: A Population‐Based Study From Japan

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Trisomy 13, the third most common autosomal trisomy after trisomy 21 and trisomy 18, is associated with a significantly high infant mortality rate. However, large‐scale studies examining causes of death in trisomy 13 remain scarce. Therefore, we aimed to better understand the mortality patterns.
