Optical coherence tomography imaging of evoked neural activity in sciatic nerve of rat [PDF]

, 2020
Significance: Imaging neural activity in myelinated tissue using optical coherence tomography (OCT) creates new possibilities for functional imaging in the peripheral and central nervous systems. Aim: To investigate changes in OCT images in response to evoked neural activity in sciatic nerve of rat in vitro.

A novel statistical methodology for quantifying the spatial arrangements of axons in peripheral nerves [PDF]

arXiv, 2022
A thorough understanding of the neuroanatomy of peripheral nerves is required for a better insight into their function and the development of neuromodulation tools and strategies. In biophysical modeling, it is commonly assumed that the complex spatial arrangement of myelinated and unmyelinated axons in peripheral nerves is random, however, in reality ...

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 ...

Development and training of a machine learning algorithm to identify patients at risk for recurrence following an arthroscopic Bankart repair (CLEARER): protocol for a retrospective, multicentre, cohort study

BMJ Open, 2022
Introduction Shoulder instability is a common injury, with a reported incidence of 23.9 per 100 000 person-years. There is still an ongoing debate on the most effective treatment strategy.

Lumbosacral Plexogram: An Aid to Reconstructive Nerve Possibilities in the Lower Extremity

Plastic and Reconstructive Surgery, Global Open
Summary:. The lumbosacral plexus is the network of nerves responsible for the motor and sensory function of the pelvis and lower limb. Our observation is that the anatomy of this plexus is less familiar to surgeons than that of the brachial plexus ...

Unusual Surgical Resection of Asymptomatic Schwannoma of the Cervical Vagus Nerve With Risk of Stroke: Case Report

Case Reports in Surgery
Schwannomas are the most common tumors of the peripheral nerves, originating from their support cells, the Schwann cells. The location of the tumor in the vagus nerve is rare.

Iron role paradox in nerve degeneration and regeneration [PDF]

Bolandghamat, S., & Behnam-Rassouli, M. (2024). Iron role paradox in nerve degeneration and regeneration. Physiological Reports, 12, e15908
Iron accumulates in the neural tissue during peripheral nerve degeneration. Some studies have already been suggested that iron facilitates Wallerian degeneration (WD) events such as Schwann cell de-differentiation. On the other hand, intracellular iron levels remain elevated during nerve regeneration and gradually decrease.

Refining the NaV1.7 pharmacophore of a class of venom‐derived peptide inhibitors via a combination of in silico screening and rational engineering

FEBS Letters, EarlyView.
Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Simulating optical coherence tomography for observing nerve activity: a finite difference time domain bi-dimensional model [PDF]

PLOS ONE 2018, 13, 1-14, 2017
We present a finite difference time domain (FDTD) model for computation of A line scans in time domain optical coherence tomography (OCT). By simulating only the end of the two arms of the interferometer and computing the interference signal in post processing, it is possible to reduce the computational time required by the simulations and, thus, to ...

Autophagy in cancer and protein conformational disorders

FEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.
