Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

Advanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Monocyte‐Differentiation‐Activated Fluorescent “Scout” Probe for Precise in Vivo Detection of Vulnerable Plaque

Advanced Science, EarlyView.
An innovative monocyte‐differentiation‐activated fluorescent “scout” probe (MDAF) leverages the inherent chemotaxis of monocytes toward vulnerable plaques (VAP) to enable efficient targeted delivery while achieving spatiotemporally controllable activation of its AIE fluorescent signals with the dynamic differentiation of monocytes, providing an ...

Intravascular ultrasound imaging as a novel tool for the diagnosis of endofibrosis

Journal of Vascular Surgery Cases and Innovative Techniques, 2016
Given the rise of high-intensity sport athletes and the paucity of literature on endofibrosis, we describe a novel adjunctive imaging technique to aid in diagnosis. A 41-year-old female triathlete presented with exercise-limiting claudication. Results of

Intravascular Polarimetry: Clinical Translation and Future Applications of Catheter-Based Polarization Sensitive Optical Frequency Domain Imaging

Frontiers in Cardiovascular Medicine, 2020
Optical coherence tomography (OCT) and optical frequency domain imaging (OFDI) visualize the coronary artery wall and plaque morphology in great detail. The advent of these high-resolution intracoronary imaging modalities has propelled our understanding ...

Soft‐Drug‐Inspired MnSTF Nano‐Adjuvant for Safe and Synergistic cGAS–STING Activation in Tumor Immunotherapy

Advanced Science, EarlyView.
This study introduces MnSTF, a soft‐drug‐inspired nanoadjuvant that overcomes the systemic toxicity of STING agonists. Through Mn2+ coordination with an ENPP1 inhibitor, it enables safe cGAS‐STING activation, remodels the tumor immune microenvironment, and synergizes with radiotherapy or vaccines to elicit robust antitumor immunity.

Loss of hepatic SMLR1 causes hepatosteatosis and protects against atherosclerosis due to decreased hepatic VLDL secretion

Hepatology, EarlyView., 2022
The role of SMLR1 in lipid metabolism (high fat + cholesterol diet in mice) Abstract Background and Aims The assembly and secretion of VLDL from the liver, a pathway that affects hepatic and plasma lipids, remains incompletely understood. We set out to identify players in the VLDL biogenesis pathway by identifying genes that are co‐expressed with the ...

Wilms′ tumor with intravascular extension: A review article

Journal of Indian Association of Pediatric Surgeons, 2014
Intravascular extension of Wilms′ tumor is a well-recognized phenomenon. Intravascular extension into the vena cava occurs in only 4-8% of patients with Wilms′ tumors and intraatrial extension occurs in around 1-3% of patients.

Intravascular magnetic resonance imaging (MRI) [PDF]

, 2014
This chapter discusses the advantages of using MRI in intravascular operations. Beginning with a brief explanation of some sample intravascular MR operations, the chapter goes on to outline the visualization problem of catheters under MRI. Some of the fundamental catheter coil designs are shown and a range of imaging techniques for catheter tracking ...

Stimuli‐Responsive Supramolecular Biomaterials for Cancer Theranostics

Advanced Science, EarlyView.
The ultimate goal of cancer theranostics is to get imaging agents and therapeutic cargo to tumor sites when and where they are required. “Smart” systems should be developed. This review discusses the characteristics of physiological stimuli, types and action modes of external stimuli, construction approaches and working principles, as well as ...
