Neurogenesis and apoptosis in the developmentally regulated loss of spinal cord regeneration. [PDF]

open access: yes, 2006
Unlike the adult mammal, the chick can successfully regenerate its spinal cord until embryonic day (E) 13. Multiple factors may contribute to the subsequent loss of regenerative capacity, although most research has concentrated on axonal re-growth ...

Ischemia–reperfusion injury after spinal cord decompressive surgery—An in vivo rat model

open access: yesAnimal Models and Experimental Medicine
Background Although decompression surgery is the optimal treatment for patients with severe degenerative cervical myelopathy (DCM), some individuals experience no improvement or even a decline in neurological function after surgery, with spinal cord ...

A Worm‐Inspired Origami Robot with Multimodal Locomotion for Adaptive Mobility in Complex Pipeline Environments

open access: yesAdvanced Science, EarlyView.
An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

Robotics Training Algorithms for Optimizing Motor Learning in Spinal Cord Injured Subjects [PDF]

open access: yes, 2007
The circuitries within the spinal cord are remarkably robust and plastic. Even in the absence of supraspinal control, such circuitries are capable of generating functional movements and changing their level of excitability based on a specific ...

Endothelial YAP Signaling Promotes Blood‐Spinal Cord Barrier Repair in Mice After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Endothelial YAP is required for blood‐spinal cord barrier repair after spinal cord injury. YAP‐dependent vascular repair is associated with ANGPT1/PI3K/AKT signaling in vivo and may involve endothelial‐pericyte paracrine interactions. By supporting vascular remodeling, tight junction restoration, restored pericyte coverage, and astrocyte‐vascular ...

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

open access: yesAdvanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Neuromorphic Devices and Computing for Sensing, Memory, and Control

open access: yesAdvanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Combined cerebellar and bilateral cervical posterior spinal artery stroke demonstrated on MRI [PDF]

open access: yes, 2003
Combined cerebellar and spinal ischemic stroke is a rare, critical condition. We report a patient with combined cerebellar and bilateral posterolateral cervical spinal cord infarction due to bilateral stenosis of the vertebral arteries. MRI is the method

A case of cervicomedullary junction compression

open access: yesJournal of Pediatric Critical Care, 2017
The C-V junction is a transition site between mobile cranium and relatively rigid spinal column. It is also the site of the medullo-spinal junction. CV anomalies are defects of development, not necessarily congenital and may not manifest at birth.

Photobiomodulation‑Engineered Extracellular Vesicles Enhance Neural Differentiation via UFL1‑Mediated UFMylation in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward
