Wall Orientation and Shear Stress in the Lattice Boltzmann Model

, 2012
The wall shear stress is a quantity of profound importance for clinical diagnosis of artery diseases. The lattice Boltzmann is an easily parallelizable numerical method of solving the flow problems, but it suffers from errors of the velocity field near ...

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

Advanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...

PM2.5 Induce Endothelial‐Mesenchymal Transition and Cardiac Fibrosis via the NCOA4‐Mediated Ferritinophagy

Advanced Science, EarlyView.
This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

CARD9 Conveys Pancreatic Islet Sympathetic Nervous β2 Signals to Reshape Macrophage Creatine Metabolism in Type 1 Diabetes

Advanced Science, EarlyView.
This study identifies CARD9 as a key mediator linking sympathetic β2‐adrenergic receptor signaling to macrophage creatine metabolism, inflammatory polarization, and neuronal integrity. Loss of β2‐AR‐PKA‐CREB1‐CARD9 signaling in macrophages reduces creatine uptake, promotes pro‐inflammatory macrophage activation, and drives sympathetic axon ferroptosis.

Extended aortic coverage in thoracic aortic endovascular repair is not associated with spinal cord ischemiaCentral MessagePerspective

JTCVS Open
Objective: Spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) remains a debilitating complication, occurring in 10% of patients. Studies have shown that extended aortic coverage is a risk factor for SCI.

Unusual echocardiographic finding leading to diagnosis of pulmonary sequestration [PDF]

, 2008
Pulmonary sequestration is an embryonic mass of non- functioning lung tissue that does not communicate with the tracheobronchial tree and has a reported incidence of 0.15%-6.4% of all the pulmonary malformations.
