A better understanding of the mechanisms of nerve regeneration could improve the outcome of surgical nerve repair. We have previously shown that axonal regeneration is increased by nerve growth factor. Neurotrophin-3 (NT-3) belongs to the same family as nerve growth factor but acts on a distinct neuron subpopulation. As little is known about its role(More)
Recent evidence suggests that the molecular defects associated with the development of diabetes also contribute to an increased risk of all types of dementia, including Alzheimer's disease, vascular dementia and Pick's disease. Indeed, the presence of type II diabetes mellitus results in a two to three fold higher risk of developing dementia [Fontbonne et(More)
Peripheral nerve transection induces significant changes in neuropeptide expression and content in injured primary sensory neurons, possibly due to loss of target derived neurotrophic support. This study shows that neurotrophin-3 (NT-3) delivery to the injured nerve influences neuropeptide Y (NPY) expression within dorsal root ganglia (DRG) neurons. NT-3(More)
Whilst increases in capillary number and permeability occurring during nerve regeneration suggest an interaction between regenerating axons and blood vessels, clinical attempts to improve nerve regeneration by augmenting nerve graft vascularisation have produced conflicting results and the nature of their relationship remains obscure. A better understanding(More)
Ketamine alone or supplemented by diazepam or xylazine has been used and evaluated as an anaesthetic in a range of animals including snakes, tortoises, lizards, birds, ferrets, dogs, cats, pigs, sheep, goats, non-human primates, rabbits, guinea pigs, rats, mice and hamsters. Ketamine alone has severe limitations in most species, but in combination has(More)
Poly-3-hydroxybutyrate (PHB), a bacterial storage product, is available as bioabsorbable sheets and has been used in this study for primary nerve repair. The aim was to assess axonal regeneration following such repair and determine the inflammatory response to PHB. In 20 adult cats, the transected superficial radial nerve was wrapped in PHB sheets, while(More)
This study investigated target specificity during axonal regeneration of a mixed motor and sensory nerve towards respective targets. The femoral nerves in rats were divided and allowed to grow across a 6 mm gap interposed with frozen and thawed muscle grafts towards their distal motor and sensory nerve stumps. Fourteen weeks later the number of motoneurons(More)
OBJECTIVE To examine whether the inflammatory phenotype found in obese and diabetic individuals is preserved in isolated, cultured myocytes and to assess the effectiveness of pharmacological AMP-activated protein kinase (AMPK) activation upon the attenuation of inflammation in these myocytes. RESEARCH DESIGN AND METHODS Muscle precursor cells were(More)
The importance of AMP-activated protein kinase (AMPK) and protein kinase C (PKC) as effectors of metformin (Met) action on glucose uptake (GU) in skeletal muscle cells was investigated. GU in L6 myotubes was stimulated 2-fold following 16 h of Met treatment and acutely enhanced by insulin in an additive fashion. Insulin-stimulated GU was sensitive to PI3K(More)
Soluble fibronectin and nerve growth factor (NGF) promote axonal regeneration when placed in silicone tubes. We investigated the ability of orientated fibronectin mats to bind and release bioactive NGF and the possibility of augmenting axonal regeneration following axotomy by using fibronectin conduits impregnated with NGF. The release of NGF was quantified(More)
