Electrical Stimulation Therapy – Dedicated to the Perfect Plastic Repair

Advanced Science, EarlyView.
This review discusses various types of electrical stimulation sources and materials, delving into the roles and mechanisms of electrical stimulation therapy in plastic surgery for tissue repair. This work broadens the clinical perspective of electrical stimulation, covering diverse repair needs from bone to soft tissues, and provides insights into ...

Tuning PAK Activity to Rescue Abnormal Myelin Permeability in HNPP.

PLoS Genetics, 2016
Schwann cells in the peripheral nervous systems extend their membranes to wrap axons concentrically and form the insulating sheath, called myelin. The spaces between layers of myelin are sealed by myelin junctions.

Interaction of PLP with GFP-MAL2 in the human oligodendroglial cell line HOG. [PDF]

PLoS ONE, 2011
The velocity of the nerve impulse conduction of vertebrates relies on the myelin sheath, an electrically insulating layer that surrounds axons in both the central and peripheral nervous systems, enabling saltatory conduction of the action potential ...

AxonCallosumEM Dataset: Axon Semantic Segmentation of Whole Corpus Callosum cross section from EM Images [PDF]

arXiv, 2023
The electron microscope (EM) remains the predominant technique for elucidating intricate details of the animal nervous system at the nanometer scale. However, accurately reconstructing the complex morphology of axons and myelin sheaths poses a significant challenge.

A Jones matrix formalism for simulating three-dimensional polarized light imaging of brain tissue [PDF]

Menzel M, Michielsen K, De Raedt H, Reckfort J, Amunts K, Axer M. 2015 A Jones matrix formalism for simulating three-dimensional polarized light imaging of brain tissue. J. R. Soc. Interface 12: 20150734, 2015
The neuroimaging technique three-dimensional polarized light imaging (3D-PLI) provides a high-resolution reconstruction of nerve fibres in human post-mortem brains. The orientations of the fibres are derived from birefringence measurements of histological brain sections assuming that the nerve fibres - consisting of an axon and a surrounding myelin ...

Deciphering Auditory Hyperexcitability in Otogl Mutant Mice Unravels an Auditory Neuropathy Mechanism

Advanced Science, EarlyView.
By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Understanding and treating ejaculatory dysfunction in men with diabetes mellitus

Andrology, Volume 11, Issue 2, Page 379-398, February 2023., 2023
Abstract Diabetes mellitus is a rapidly rising metabolic disorder with important systemic complications. Global figures have demonstrated the prevalence of diabetes mellitus has almost quadrupled from 108 million in 1980 to 422 million in 2014, with a current prevalence of over 525 million.

Currents and K-functions for Fiber Point Processes [PDF]

arXiv, 2021
Analysis of images of sets of fibers such as myelin sheaths or skeletal muscles must account for both the spatial distribution of fibers and differences in fiber shape. This necessitates a combination of point process and shape analysis methodology. In this paper, we develop a K-function for shape-valued point processes by embedding shapes as currents,

Junctions tighten myelin sheaths

The Journal of Cell Biology, 2005
![][1] Claudin-19 (green) helps form tight junction structures that seal PNS myelin sheaths. Tight junction-like structures run along myelin sheaths in both the central and peripheral nervous systems (CNS and PNS), but have only been functionally characterized in the CNS.

MyelTracer: A Semi-Automated Software for Myelin g-Ratio Quantification

eNeuro, 2021
Visual Abstract In the central and peripheral nervous systems, the myelin sheath promotes neuronal signal transduction. The thickness of the myelin sheath changes during development and in disease conditions like multiple sclerosis.
