Halo Sign on Temporal Artery Ultrasound Aids in Prompt Diagnosis of Giant Cell Arteritis

Methodist DeBakey Cardiovascular Journal
Giant cell arteritis (GCA) is the most common form of systemic vasculitis in individuals over 50 years old. The most feared complication of GCA is permanent blindness, which can be prevented by prompt diagnosis and immediate treatment.

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.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Continuum Robots in Surgery: From Engineering Design to Clinical Practice

Advanced Robotics Research, EarlyView.
The hyper‐redundant nature of continuum robot structures enables near‐infinite degrees of freedom leading to immense potential for medical applications. This review provides a historical background of continuum robots and novel ideas shaping their progress to current structural design, sensing technology, modeling techniques, and control methods.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Magnetically Actuated Microrobot for Drug Delivery: Current Progress and Challenges

Advanced Robotics Research, EarlyView.
Magnetically actuated microrobots are reshaping targeted drug delivery through wireless propulsion, programmable materials, and localized therapeutic release. This review examines how fabrication, body material selection, structural architecture, loading mechanisms, and imaging‐guided control converge to enable microrobotic therapies while identifying ...

Antineutrophil Cytoplasmic Antibody–Associated Vasculitis Masquerading as Giant Cell Arteritis

Annals of Internal Medicine: Clinical Cases
The triad of temporal artery tenderness, monocular vision loss, and raised inflammatory markers is suggestive of giant cell arteritis (GCA). We encountered a 76-year-old woman who presented with acute right eye vision loss, temporal tenderness, jaw ...
