Background Surgical treatment of neuromas involves excision of neuromas proximally to the level of grossly "normal" fascicles; however, proximal changes at the axonal level may have both functional and therapeutic implications with regard to amputated ...

Intrinsic dynamical fluctuations of PNS myelin [PDF]
The ultrastructure fluctuations and complex dynamics of the multi-layered membrane structure of myelin are fundamental for understanding and control its formation process and its degeneration and repair in neurological diseases such as multiple sclerosis (MS).

Tumor microenvironment (Part I): Tissue integrity in a rat model of peripheral neural cancer [PDF]
ICAM-1 (intercellular adhesion molecule 1) and MPZ (myelin protein zero) are thought to be a factor in the integrity of nerve tissues. In this report, we attempted to trace the expression of ICAM-1, responsible for cell-to-cell adhesion, and of MPZ, the main constituent of myelin sheath, in malignant tissues of the sciatic nerve (SN) in inbred male ...

Quantitative T1 is sensitive to cortical remyelination in multiple sclerosis: A postmortem MRI study
In a post‐mortem study using multiparametric qMRI of whole fixed human brains from people with multiple sclerosis (pwMS), we found evidence that quantitative T1 (qT1) is sensitive to remyelination in the cortex. In contrast, QSM and radial diffusivity were affected by cortical pathology independently of remyelination. Our data suggest that qT1 could be

Cell vibron polariton in the myelin sheath of nerve [PDF]
Polaritons are arousing tremendous interests in physics and material sciences for their unique and amazing properties, especially including the condensation, lasing without inversion and even room-temperature superfluidity. Herein, we propose a cell vibron polariton (cell-VP): a collectively coherent mode of a photon and all phospholipid molecules in a

The regeneration of LC‐NE from pluripotent stem cells (PSCs) could significantly mitigate the progression of Neurodegenerative diseases and alleviate associated psychiatric disease symptoms, providing a new approach to the treatment of neurological diseases.

Quantitative Ultrasound and B-mode Image Texture Features Correlate with Collagen and Myelin Content in Human Ulnar Nerve Fascicles [PDF]
We investigate the usefulness of quantitative ultrasound (QUS) and B-mode texture features for characterization of ulnar nerve fascicles. Ultrasound data were acquired from cadaveric specimens using a nominal 30 MHz probe. Next, the nerves were extracted to prepare histology sections.

Exercise Delays Brain Ageing Through Muscle‐Brain Crosstalk
This graphical abstract illustrates the reciprocal crosstalk between the brain and peripheral organs, highlighting the profound impact of exercise on brain health through systemic interactions. It underscores how exercise influences the brain via signals from various organs and, conversely, how the brain modulates functions of peripheral organs.

THE EFFECTS OF NERVE GROWTH FACTOR ON MYELINATION OF REGENERATED FIBERS IN RAT [PDF]
The effect of nerve growth factor (NGF) on regeneration of rat sciatic nerves in adult rat was studied. The sciatic nerve was cut out across a 6‑mm gap, then the proximal and distal stumps were inserted into the silicone tube chamber.

Specific Iron Binding to Natural Sphingomyelin Membrane Induced by Non-Specific Co-Solutes [PDF]
Hypothesis: Sphingomyelin (SPM), a crucial phospholipid in the myelin sheath, is vital in insulating nerve fibers. We hypothesize that iron ions selectively bind to the phosphatidylcholine (PC) template within the SPM membrane under near-physiological conditions, disrupting membrane organization.
