Nerves and Anesthesia: A physics perspective on medicine [PDF]

Anestezjologia i Ratownictwo 2014; 8: 252-263, 2014
We present a recent theory for nerve pulse propagation and anesthesia and argue that both nerve activity and the action of anesthetics can be understood on the basis of simple physical laws. It was found experimentally that biological membranes melt from a solid state to a liquid state just below physiological temperature. Such melting processes have a

Microvesicles as vehicles for tissue regeneration: Changing of the guards [PDF]

, 2016
Purpose of Review: Microvesicles (MVs) have been recognised as mediators of stem cell function, enabling and guiding their regenerative effects. Recent Findings: MVs constitute one unique size class of extracellular vesicles (EVs) directly shed from ...

SARS‐CoV‐2 Is Linked to Brain Volume Loss in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The impact of SARS‐CoV‐2 infection on brain and spinal cord pathology in patients with multiple sclerosis (pwMS) remains unclear. We aimed to describe changes in brain lesion activity and brain and spinal cord volumes following SARS‐CoV‐2 infection.

Multiple Instance Segmentation in Brachial Plexus Ultrasound Image Using BPMSegNet [PDF]

arXiv, 2020
The identification of nerve is difficult as structures of nerves are challenging to image and to detect in ultrasound images. Nevertheless, the nerve identification in ultrasound images is a crucial step to improve performance of regional anesthesia.

The NMDA receptor functions independently and as an LRP1 co-receptor to promote Schwann cell survival and migration [PDF]

, 2015
NMDA Receptors (NMDA-Rs) are ionotropic glutamate receptors, which associate with LDL Receptor-related Protein-1 (LRP1) to trigger cell-signaling in response to protein ligands in neurons.

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

Advanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

Molecular Weight Distribution of Proteins Synthesized in Single, Identified Neurons of Aplysia [PDF]

, 1971
Parietovisceral ganglia from Aplysia californica were incubated in medium containing leucine-3H. Single, identified nerve cell somas were isolated from the ganglia, and their proteins extracted and separated by electrophoresis on 5% SDS-polyacrylamide ...

Gene expression patterns specific to the regenerating limb of the Mexican axolotl

Biology Open, 2012
Summary Salamander limb regeneration is dependent upon tissue interactions that are local to the amputation site. Communication among limb epidermis, peripheral nerves, and mesenchyme coordinate cell migration, cell proliferation, and tissue patterning ...

Automatic Tissue Differentiation in Parotidectomy using Hyperspectral Imaging [PDF]

Current Directions in Biomedical Engineering 10(4):682-685, 2024
In head and neck surgery, continuous intraoperative tissue differentiation is of great importance to avoid injury to sensitive structures such as nerves and vessels. Hyperspectral imaging (HSI) with neural network analysis could support the surgeon in tissue differentiation. A 3D Convolutional Neural Network with hyperspectral data in the range of $400-
