Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Assessment of coronary artery outward remodeling in consequence of excision of epicardial adipose tissue in Ossabaw swine [PDF]

, 2017
Background Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow,

NFS1 Regulates IDH2 to Attenuate Abdominal Aortic Aneurysms via Interacting With SP2

Advanced Science, EarlyView.
The loss of NFS1 leads to its reduced binding with the transcription factor SP2, resulting in decreased expression of the downstream gene Idh2. This causes a shift in energy supply toward glycolysis in VSMCs, ultimately contributing to the occurrence and progression of AAA.

Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration

Advanced Science, EarlyView.
A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.
