A Diffusion MRI model for axonal damage quantification based on axial diffusivity reduction in axons: a Monte Carlo simulation study [PDF]
arXivAxonal damage is the primary pathological correlate of long-term impairment in multiple sclerosis (MS). Previous work has demonstrated a strong, quantitative relationship between decrease in axial diffusivity and axonal damage. In the present work, we develop an extension of diffusion basis spectrum imaging (DBSI) which can be used to quantify the ...

Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits
Advanced Materials Technologies, EarlyView.This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or

Advanced Optical Materials, EarlyView.Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Axon-axon and axon-target interactions underlying somatosensory circuit assembly in Drosophila
, 2019 Sensory axons from functionally related neurons often project to similar regions in the central nervous system (CNS). Various cell-cell interactions and activity-dependent mechanisms contribute to the formation of these arrangements, but it remains unclear how they ultimately influence circuit wiring and function. I examined mechanisms of somatosensory

The Journal of Cell Biology, 2003 If you've seen one microtubule, you've seen them all. Not true, according to Nakata and Hirokawa, who demonstrate on page 1045 that a unique set of micro- tubules is crucial for protein targeting in neurons. Figure Vesicles move into the axon on a unique set of microtubules (green).

Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration
Advanced Therapeutics, EarlyView.Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

Scattering approach to diffusion quantifies axonal damage in brain injury [PDF]
arXivEarly diagnosis and noninvasive monitoring of neurological disorders require sensitivity to elusive cellular-level alterations that occur much earlier than volumetric changes observable with the millimeter-resolution of medical imaging modalities. Morphological changes in axons, such as axonal varicosities or beadings, are observed in neurological ...
