Biomechanics of Aortic Dissection: A Comparison of Aortas Associated With Bicuspid and Tricuspid Aortic Valves

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Current methods for aortic dissection risk assessment are inadequate for patients with ascending aortic aneurysms associated with either bicuspid aortic valves (BAVs) or tricuspid aortic valves (TAVs).

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Artificial intelligence in the diagnosis of thoracic aortic aneurysms in a retrospective chest computed tomography scan analysis

Digital Diagnostics, 2023
BACKGROUND: Aortic aneurysms, known as silent killers, are frequently asymptomatic, leading to vessel rupture and death. Annual rates for ruptures, stratifications, and sudden deaths are up to 3.6%, 3.7%, and 10.8%, respectively.

Expandable Nanocomposite Shape‐Memory Hemostat for the Treatment of Noncompressible Hemorrhage

Advanced Science, EarlyView.
A nanocomposite‐coated shape memory foam rapidly expands, accelerates clotting, and reduces blood loss in vivo. Its fast volumetric expansion and strong procoagulant activity make it a promising hemostat for treating deep, noncompressible hemorrhage.

CDK4/6 Inhibition Induces CD8+ T Cell Antitumor Immunity via MIF‐Induced Functional Orchestration of Tumor‐Associated Macrophages

Advanced Science, EarlyView.
CDK4/6 inhibition promotes CD8+ T cell expansion through tumor‐macrophage crosstalk by activating HIF‐1α and enhancing MIF‐CD44/CD74 signaling. This reprograms TAMs to boost MHC‐I antigen presentation, and CDK4/6 inhibitor‐trained M1 TAM supernatant therapy synergizes with low‐dose PD‐1 blockade to restore antitumor immunity.

Biomechanical properties of the aortic root are distinct from those of the ascending aorta in both normal and aneurysmal statesCentral MessagePerspective

JTCVS Open, 2023
Background: Although aneurysms of the ascending aorta and the aortic root are treated similarly in clinical guidelines, how biomechanical properties differ between these 2 segments of aorta is poorly defined.

Abdominal Aortic Aneurysm

The Journal of Clinical Hypertension, 2004
An abdominal aortic aneurysm (AAA) is defined as a localized dilation of the artery that is 1.5 times the diameter of the normal segment. The most common location for an aortic aneurysm is the infrarenal segment where a diameter that exceeds 3 cm in diameter is considered aneurysmal.

Fibroblast Activation Protein Promotes Thoracic Aortic Dissection via PLAUR/ITGB1‐Mediated Pro‐inflammatory Macrophage Polarization

Advanced Science, EarlyView.
This study reveals that FAP promotes thoracic aortic dissection (TAD) through a nonenzymatic mechanism involving fibroblast‐macrophage crosstalk via the FAP/PLAUR/ITGB1/FAK axis. Targeting this pathway might offer a promising therapeutic strategy for TAD.
