A case involving a bovine aortic arch contributing to blunt thoracic aortic injury of triple rupture close to the pericardial reflection

open access: yesTrauma Case Reports
A blunt thoracic aortic injury is a fatal condition that often requires emergency surgery. Although injuries to the aortic isthmus are common in trauma patients, the proximal aortic arch often remains intact.

Phase Separation of TRIM21 Modulates PTPN14 Stability to Drive Flow‐Dependent Endothelial Activation and Atherogenesis

open access: yesAdvanced Science, EarlyView.
Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

Endovascular treatment of a descending thoracic aorta aneurysm in a patient with right sided aortic arch: a case report

open access: yesCVIR Endovascular
Backround Right-sided aortic arch is a rare congenital variant. The Edwards classification describes three types of right sided-aortic arch: right aortic arch with aberrant left subclavian artery, right aortic arch with mirror image branching, and right ...

Type III aortic arch angulation increases aortic stiffness: Analysis from an ex vivo porcine modelCentral MessagePerspective

open access: yesJTCVS Open
Objective: The relationship among increased aortic arch angulation, aortic flow dynamics, and vessel wall stiffness remains unclear. This experimental ex vivo study investigated how increased aortic arch angulation affects aortic stiffness and stent ...

Serial Molecular‐Microstructural Multimodal Intravascular Imaging of Atherosclerotic Plaques in Mice

open access: yesAdvanced Science, EarlyView.
A novel longitudinal molecular and microstructural intravascular imaging approach is developed to study murine atherosclerosis. The technique combines a unique surgical model with a miniaturized multimodal device to detect macrophage activity and lipid simultaneously.

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

open access: yesAdvanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Subclavian steal syndrome in a right aortic arch with aberrant left subclavian artery atresia

open access: yesSAGE Open Medical Case Reports, 2023
Congenital aortic arch anomalies are an uncommon diagnosis resulting from embryologic malformations during the fourth to eighth week of gestation. Asymptomatic variants frequently are overlooked in the perinatal period and diagnosed incidentally during ...

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

open access: yesAdvanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...
