Proximal Nerve Complexes. A Computational Topology Approach [PDF]
arXiv, 2017 This article introduces a theory of proximal nerve complexes and nerve spokes, restricted to the triangulation of finite regions in the Euclidean plane. A nerve complex is a collection of filled triangles with a common vertex, covering a finite region of the plane. Structures called $k$-spokes, $k\geq 1$, are a natural extension of nerve complexes.

Equine Veterinary Journal, EarlyView.Abstract Botulism is a severe and often fatal disease in equine patients worldwide. Clostridium botulinum is a ubiquitous soil organism which produces a potent neurotoxin resulting in neuromuscular blockade and flaccid paralysis in affected animals. Definitive diagnosis is often impractical or impossible, leading to diagnosis and treatment based on ...

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, e15908Iron 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.

NerVE: Neural Volumetric Edges for Parametric Curve Extraction from Point Cloud [PDF]
arXiv, 2023 Extracting parametric edge curves from point clouds is a fundamental problem in 3D vision and geometry processing. Existing approaches mainly rely on keypoint detection, a challenging procedure that tends to generate noisy output, making the subsequent edge extraction error-prone. To address this issue, we propose to directly detect structured edges to

Journal of Fish Biology, EarlyView.Abstract Hudsonius hudsonius (Cypriniformes: Leuciscidae), commonly known as the spottail shiner, is a small cyprinoid fish species found across much of North America. H. hudsonius has traditionally been regarded as one of the most basal and plesiomorphic species among the notropin fishes, that is, fishes traditionally placed in or associated with the ...

Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds
Experimental Physiology, EarlyView.Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal

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

The Anatomical Record, Volume 308, Issue 7, Page 1994-2037, July 2025.Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

Glossopharyngeal schwannoma as a differential for a cerebellopontine angle mass
Otolaryngology Case Reports, 2022 We report a case of cerebellopontine angle tumour, presenting with hearing loss, tinnitus, and vertigo. This turned out to be a glossopharyngeal schwannoma. This has potential implications on selection of surgical approach and preoperative counselling of
