Spotlight on nerves: Portable multispectral optoacoustic imaging of peripheral nerve vascularization and morphology [PDF]

arXiv, 2022
Various morphological and functional parameters of peripheral nerves and their vascular supply are indicative of pathological changes due to injury or disease. Based on recent improvements in optoacoustic image quality, we explore the ability of multispectral optoacoustic tomography, in tandem with ultrasound imaging (OPUS), to investigate the vascular

Quantitative mass spectrometry analysis of the injured proximal and distal human digital nerve ends

Frontiers in Molecular Neuroscience
IntroductionProteomic analysis of injured human peripheral nerves, particularly focusing on events occurring in the proximal and distal nerve ends, remains relatively underexplored.

ELISA Detection of Endogenous Serum Albumin in the Mouse Brain: A Measure of Extravasation Following Brain Injury

Bio-Protocol, 2015
After stroke and brain contusion, serum proteins extravasate into nerve tissue through disrupted blood-brain barrier (BBB). Because extravasations of serum proteins result in vasogenic brain edema, serum albumin level in the brain is an indicator of BBB

New insights into the interplay between autophagy and oxidative and endoplasmic reticulum stress in neuronal cell death and survival

Frontiers in Cell and Developmental Biology, 2022
Autophagy is a dynamic process that maintains the normal homeostasis of cells by digesting and degrading aging proteins and damaged organelles. The effect of autophagy on neural tissue is still a matter of debate.

Automatic Ultrasound Image Segmentation of Supraclavicular Nerve Using Dilated U-Net Deep Learning Architecture [PDF]

arXiv, 2022
Automated object recognition in medical images can facilitate medical diagnosis and treatment. In this paper, we automatically segmented supraclavicular nerves in ultrasound images to assist in injecting peripheral nerve blocks. Nerve blocks are generally used for pain treatment after surgery, where ultrasound guidance is used to inject local ...

A model of electrical impedance tomography on peripheral nerves for a neural-prosthetic control interface [PDF]

Hope, J., Vanholsbeeck, F., McDaid, A., A model of electrical impedance tomography implemented in nerve-cuff for neural-prosthetics control. Physiological Measurement, 2018, 2017
Objective: A model is presented to evaluate the viability of using electrical impedance tomography (EIT) with a nerve cuff to record neural activity in peripheral nerves. Approach: Established modelling approaches in neural-EIT are expanded on to be used, for the first time, on myelinated fibres which are abundant in mammalian peripheral nerves and ...

Biomechanical, ultrastructural, and electrophysiological characterization of the non-human primate experimental glaucoma model. [PDF]

, 2017
Laser-induced experimental glaucoma (ExGl) in non-human primates (NHPs) is a common animal model for ocular drug development. While many features of human hypertensive glaucoma are replicated in this model, structural and functional changes in the ...

Proteomic profiling of neuromas reveals alterations in protein composition and local protein synthesis in hyper-excitable nerves

Molecular Pain, 2008
Neuropathic pain may arise following peripheral nerve injury though the molecular mechanisms associated with this are unclear. We used proteomic profiling to examine changes in protein expression associated with the formation of hyper-excitable neuromas ...

Predicting multicellular function through multi-layer tissue networks [PDF]

Bioinformatics 2017, 33 (14): i190-i198, 2017
Motivation: Understanding functions of proteins in specific human tissues is essential for insights into disease diagnostics and therapeutics, yet prediction of tissue-specific cellular function remains a critical challenge for biomedicine. Results: Here we present OhmNet, a hierarchy-aware unsupervised node feature learning approach for multi-layer ...
