Cluster Analysis of Myelin Nerve Fibers of the Periferal Nerve

Archive of Clinical Medicine, 2020
One of the unsolved issues in neuromorphology is the classification of myelin nerve fibers (MNF). Objective: to use cluster analysis to classify the sciatic nerve MNF. Material and methods. The work was performed using 5 one-year-old male Wistar rats. Semi-thin sections were stained with methylene blue. MNF morphometry was performed using ImageJ,

Peroxisomal dysfunctions cause lysosomal storage and axonal Kv1 channel redistribution in peripheral neuropathy [PDF]

, 2017
Impairment of peripheral nerve function is frequent in neurometabolic diseases, but mechanistically not well understood. Here, we report a novel disease mechanism and the finding that glial lipid metabolism is critical for axon function, independent of ...

Electrically Evoked Compound Action Potentials in Spinal Cord Stimulation: Implications for Preclinical Research Models

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives The study aimed to assess the feasibility of recording electrically evoked compound action potentials (ECAPs) from the rat spinal cord. To achieve this, we characterized electrophysiological responses of dorsal column (DC) axons from electrical stimulation and quantified the relationship between ECAP and motor thresholds (ECAPTs and

Estimation of fiber diameters in the spinal dorsal columns from clinical data [PDF]

, 1998
Lack of human morphometric data regarding the largest nerve fibers in the dorsal columns (DCs) of the spinal cord has lead to the estimation of the diameters of these fibers from clinical data retrieved from patients with a new spinal cord stimulation ...

Engineering the Future of Restorative Clinical Peripheral Nerve Surgery

Advanced Healthcare Materials, EarlyView.
What if damaged nerves could regenerate more effectively? This review unveils cutting‐edge strategies to restore nerve function, from biomaterial scaffolds and bioactive molecules to living engineered tissues. By accelerating axonal regrowth, preserving Schwann cells, and enhancing connectivity, these approaches are reshaping nerve repair—offering new ...

The mechanosensitive ion channel TRAAK is localized to the mammalian node of Ranvier. [PDF]

, 2019
TRAAK is a membrane tension-activated K+ channel that has been associated through behavioral studies to mechanical nociception. We used specific monoclonal antibodies in mice to show that TRAAK is localized exclusively to nodes of Ranvier, the action ...

Asymptotic construction of pulses in the Hodgkin Huxley model for myelinated nerves [PDF]

, 2005
A quantitative description of pulses and wave trains in the spatially discrete Hodgkin-Huxley model for myelinated nerves is given. Predictions of the shape and speed of the waves and the thresholds for propagation failure are obtained.

Silicon Nanowire Mats Enable Advanced Bioelectrical Recordings in Primary DRG Cell Cultures

Advanced Healthcare Materials, EarlyView.
SiNW mat‐based MEA (NW_MEA) enables continuous intracellular recordings from neurons in primary rat DRG cell cultures, identifying C‐fiber nociceptors. Supported by an astrocyte feeder layer, SiNW mat promotes DRG neuron and glial cell growth, preserving in vivo‐like cell characteristics and allowing drug‐modulated activity monitoring.

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

Advanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Analysis of current density and related parameters in spinal cord stimulation [PDF]

, 1998
A volume conductor model of the spinal cord and surrounding anatomical structures is used to calculate current (and current density) charge per pulse, and maximum charge density per pulse at the contact surface of the electrode in the dorsal epidural ...
