Concomitant Surgical Atrial Fibrillation Ablation (Modified Cox Maze IV) in Patients With Long-Standing Persistent Atrial Fibrillation Undergoing Mitral Valve Surgery: Experience From a UK Tertiary Center

The Heart Surgery Forum
Background:In patients with persistent atrial fibrillation (AF) and chronic severe mitral valve (MV) regurgitation, the success rate of cardioversion and long-term maintenance of sinus rhythm is poor. Concomitant AF ablation during MV surgery may improve

LLM‐Integrated Human–Robot Interaction System for Microrobots

Advanced Robotics Research, EarlyView.
This paper proposes an LLM‐based control framework for guiding microrobots using human natural language. This framework can convert the natural human speech into safe and executable command sets for reliable navigation in complex environments. The experimental results show high accuracy and robustness in task performance, demonstrating the potential of

Stroke prevention in nonvalvular atrial fibrillation: Thoracoscopic left atrial appendage closure with or without surgical ablationCentral MessagePerspective

JTCVS Techniques
Objectives: Totally thoracoscopic left atrial appendage closure (TT-LAAC) with or without the MAZE procedure is an LAA management technique that prevents cardioembolic events by closing the LAA in patients with atrial fibrillation (AF).

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

Advanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

Advanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

Ablating adult neurogenesis in the rat has no effect on spatial processing: evidence from a novel pharmacogenetic model.

PLoS Genetics, 2013
The function of adult neurogenesis in the rodent brain remains unclear. Ablation of adult born neurons has yielded conflicting results about emotional and cognitive impairments. One hypothesis is that adult neurogenesis in the hippocampus enables spatial
