Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

Remote magnetic navigation for ventricular ablation: did the machine win this round? [PDF]

open access: yesJournal of Interventional Cardiac Electrophysiology, 2016
Remote magnetic navigation has been available as a tool for mapping and ablation for well over a decade. In that period of time, it has shown to be useful in nearly every type of ablation procedure from the most simple to the most complex [1–3]. Some operators prefer the system for atrial fibrillation ablation, others for ventricular tachycardia ...

Lateral asymmetry in the hippocampal response to the remoteness of autobiographical memories [PDF]

open access: yes, 2003
The time scale of hippocampal involvement in retrieving memories, particularly those more remote, is still a matter of debate. Some propose that the hippocampus is not involved in the retrieval of remote memories, whereas others assert that it is ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
