The Surgical Treatment for Atrial Fibrillation: Ablation Technology and Surgical Approaches

open access: yesRambam Maimonides Medical Journal, 2013
The Cox maze procedure developed originally in 1987 by Dr James Cox has evolved from a “cut and sew” surgical procedure, where the maze was applied using multiple surgical cuts, to an extensive use of surgical ablation technology where ablation lesions ...

Our experiences with tongue base radiofrequency, for treatment of obstructive sleep apnea

open access: yes, 2011
Objectives:Current opinion for the treatment of obstructive sleep apnea (OSA) leans towards minimal invasive procedures. The frequently used radiofrequency ablation technique for the treatment of tongue base hypertrophy is a favorable alternative. In our

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

open access: yesAdvanced 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.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Thermage: Monopolar radiofrequency [PDF]

open access: yesAesthetic Surgery Journal, 2005
Monopolar radiofrequency treatment may be appropriate for patients who desire skin tightening but will not tolerate surgery and/or downtime. Patients generally can expect a 5% to 20% improvement, but results in any particular group are unpredictable. Key to this treatment is providing patients with detailed information to ensure that expectations are ...

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

open access: yesAdvanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Recanalization of an occluded left pulmonary artery: A case report and review of the literature

open access: yesAnnals of Pediatric Cardiology, 2017
We report an 8-year-old male child with tetralogy of Fallot (TOF), who developed left pulmonary artery (LPA) atresia, following surgical repair of TOF and left pulmonary arterioplasty at the age of 6 years.

Hyperpolarization of [1‐13C]Ketoisocaproate‐d2 by Reversible Exchange with Parahydrogen Enables Profiling of Branched‐Chain‐Amino‐Acid Metabolism in Cellulo and in Vivo

open access: yesAdvanced Science, EarlyView.
We report the fast generation of biocompatible solutions of highly 13C‐hyperpolarized (≈11%) partially‐deuterated ketoisocaproate within <6 min using spin‐lock‐induced crossing and reversible exchange with parahydrogen (SLIC‐SABRE). This enables rapid detection of branched‐chain‐amino‐acid transferase 1 (BCAT1) protein expression and investigation of ...

From GPS to AR: Leveraging Augmented Reality and Grid-Based Systems for Improved Indoor Navigation

open access: yesIEEE Access
With the rapid growth of technology in intelligent city networks, navigating inside complex buildings has become increasingly difficult. The indoor Global Positioning System (GPS), which operates within an ultra-high radio frequency range, suffers from ...
