Optimization of Magnetic Milli‐Spinner for Robotic Endovascular Intervention

Advanced Robotics Research, EarlyView.
This work presents the design optimization of a multifunctional magnetic milli‐spinner for high‐speed propulsion and efficient clot debulking. The optimized design achieves an ultrafast swimming velocity of 55 cm/s (≈175 body lengths/s) in saline water, enabling stable upstream swimming against strong physiological flows and establishing magnetic milli‐

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...

CD4+ Tregs Drive Post‐Ischemic Sprouting Angiogenesis via Endothelial YY1/MAML1 Reactivation

Advanced Science, EarlyView.
ABSTRACT Microvascular complications of diabetes are chronic diseases of small vessels. We previously found that CD4+ regulatory T‐cells (Tregs) are markedly reduced in type 2 diabetes (T2D) after ischemic injury in both mice and humans, and that Treg deficiency in immunodeficient mice impairs vascular regeneration.

3D Large‐Scale Subwavelength‐Resolution Sound Sheet Tomography Based on an Active and Programmable Circular Meta‐Array

Advanced Science, EarlyView.
A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited

Penetrating injuries of the femoral artery

Journal of British Surgery, 1995
Abstract This is a retrospective study of 106 patients with penetrating injuries to the femoral artery. The cause of injury was gunshot in 82 per cent, stabbing in 13 per cent and pellets in 5 per cent. We believe that angiography is unnecessary in patients with ‘hard’ signs of vascular injury: 97 patients underwent immediate exploration

Legumain Restrains Granuloma Formation by Inhibiting mTORC1/STAT1‐Mediated M1 Macrophage Polarization in Sarcoidosis

Advanced Science, EarlyView.
Legumain (LGMN) is upregulated in macrophages during sarcoid‑like granuloma formation. Macrophage‑derived LGMN binds to integrin αvβ3 and suppresses mTORC1/STAT1 signaling to restrain M1 macrophage polarization. Intratracheal delivery of lipid nanoparticles carrying Lgmn plasmid DNA (pDNA) elevates LGMN expression and effectively attenuates pulmonary ...

The macroanatomic investigations on the branches of the femora) artery in the rats [PDF]

Eurasian Journal of Veterinary Sciences
In this study, the branches of the femoral artery were investigated. For this purpose, five male and five female adult rats were used. Coloured latex was injected to the abdominal aortae. It was seen that, the femoral artery which distal continued of the

Lithotripsy-assisted femoral artery access for percutaneous endovascular aortic repair

Journal of Vascular Surgery Cases and Innovative Techniques
The presence of calcification in the femoral arteries can, at times, preclude patients from undergoing percutaneous endovascular repair of the aorta.

The effect of coronary angiography and femoral access on femoral artery distensibility and elasticity

Journal of Ultrasonography, 2021
Aim of the study: The aim of this study was to evaluate the long-term effects of access to the femoral artery for the purposes of coronary angiography through the measurement of femoral artery distensibility and elasticity on the accessed and non ...
