Remodelling of coronary arteries
BMJ Case Reports, 2009 A 70-year-old man presented with a 6 month history of grade II exertional chest tightness. At peak exercise on treadmill he developed borderline ST segment depression in lead V4. Cardiac catheterisation showed angiographically minor stenosis in the proximal left anterior descending artery (fig 1).

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.
