We previously have published data detailing the time course of taste bud regeneration in the anterior tongue following transection of the chorda tympani (CT) nerve in the rat. This study extends the prior work by determining the time course of taste bud regeneration in the vallate papilla, soft palate and nasoincisor ducts (NID) following transection of either the glossopharyngeal (GL) or great...
Maintenance of ocular viability is one of the major impediments to successful whole-eye transplantation. This review provides a comprehensive understanding of the current literature to help guide future studies in order to overcome this hurdle. A systematic multistage review of published literature was performed. Three specific questions were addressed: (1) Is recovery of visual function follow...
Modulation of trigeminal spinal subnucleus caudalis neuronal activity following regeneration of transected inferior alveolar nerve in rats. To clarify the neuronal mechanisms of abnormal pain in the face innervated by the regenerated inferior alveolar nerve (IAN), nocifensive behavior, trigeminal ganglion neuronal labeling following Fluorogold (FG) injection into the mental skin, and trigeminal...
Descending activity from the brain shapes spinal cord reflex function throughout life, yet the mechanisms responsible for this spinal cord plasticity are poorly understood. Operant conditioning of the H-reflex, the electrical analogue of the spinal stretch reflex, is a simple model for investigating these mechanisms. An earlier study in the Sprague-Dawley rat showed that acquisition of an opera...
Spinal Wistar Hannover rats injected with olfactory ensheathing glia (OEG) have been shown to recover some bipedal stepping and climbing abilities. Given the intrinsic ability of the spinal cord to regain stepping with pharmacological agents or epidural stimulation after a complete mid-thoracic transection, we asked if functional recovery after OEG injections is due to changes in the caudal stu...
Background The digital flexor tendon sheath (DFTS) is a common site of pathology in the UK equine population, often necessitating tenoscopic exploration. Common intrathecal pathologies may lead to fetlock canal constriction. palmar/plantar annular ligament (PAL) surgically transected relieve constriction or facilitate surgical access and instrumentation. Objectives objectives this study were (1...
background: axotomy causes sensory neuronal loss. reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. it is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. methods: animals (male wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...
The use of high-speed puncture mechanics for prey capture has been documented across a wide range of organisms, including vertebrates, arthropods, molluscs and cnidarians. These examples span four phyla and seven orders of magnitude difference in size. The commonality of these puncture systems offers an opportunity to explore how organisms at different scales and with different materials, morph...
A numerical model for orthogonal cutting using the material point method was applied to woodcutting using a bench plane. The cutting process was modelled by accounting for surface energy associated with wood fracture toughness for crack growth parallel to the grain. By using damping to deal with dynamic crack propagation and modelling all contact between wood and the plane, simulations could in...
