Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

Advanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

Advanced Electronic Materials, EarlyView.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Design, Modeling, and Control of a Soft Robotic Diaphragm‐Assist Device in a Respiratory Simulator

Advanced Intelligent Systems, EarlyView.
A soft robotic diaphragm‐assist device using fabric‐based pneumatic actuators with a 2‐step control system to optimize synchronization and support is introduced. This system can detect the initiation of breathing to trigger assistance and regulate pressures to provide the correct level of inhalation augmentation. Validation and testing are completed on

Surgical Outcomes of Centrifugal Continuous-Flow Implantable Left Ventricular Assist Devices: Heartmate 3 versus Heartware Ventricular Assist Device

Journal of Chest Surgery
Background: Left ventricular assist devices (LVADs) are widely employed as a therapeutic option for end-stage heart failure. We evaluated the outcomes associated with centrifugal- flow LVAD implantation, comparing 2 device models: the Heartmate 3 (HM3)

E‐CAD: Electroactive Polymer‐Based Cardiac Assist Device with Low Power Consumption

Advanced Intelligent Systems, EarlyView.
Conventional cardiac assist devices often require high power, involve direct blood contact, and risk driveline infections. This work presents a soft electroactive polymer‐based system that compresses the heart externally while consuming <0.3 W. With no blood contact, a 0.3 mm driveline, and a compact design, E‐CAD demonstrates enhanced output and ...

Chromosome 3q22.2‐q26.2 Interstitial Deletion in a Patient With Wisconsin Syndrome, Blepharophimosis‐Ptosis‐Epicanthus Inversus Syndrome, Dandy‐Walker Malformation, Pierre Robin Sequence, and Recurrent Infections

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Wisconsin syndrome is a very rare genetic condition characterized by coarse facies, prominent nasal tip, bushy high arched/upsweeping eyebrows, and a full/everted lower lip. Deletion of chromosome 3q24q25 region is considered critical for its manifestation.

From Rigid to Soft Robotic Approaches for Minimally Invasive Neurosurgery [PDF]

arXiv
Robotic assistance has significantly improved the outcomes of open microsurgery and rigid endoscopic surgery, however is yet to make an impact in flexible endoscopic neurosurgery. Some of the most common intracranial procedures for treatment of hydrocephalus and tumors stand to benefit from increased dexterity and reduced invasiveness offered by ...
