The pelvic ganglia provide autonomic innervation to pelvic viscera and urogenital organs. These neurons are susceptible to axonal injury during pelvic surgical procedures, yet their regenerative mechanisms are poorly understood. The AP-1 transcription factor component, c-Jun, has been strongly linked to regenerative events in injured sensory, sympathetic(More)
Advanced glycation and lipoxidation end products (AGEs/ALEs) have been implicated in the pathogenesis of the major microvascular complications of diabetes mellitus: nephropathy, neuropathy, and retinopathy. This article reviews the evidence regarding the peripheral nerve and its vascular supply. Most investigations done to assess the role of AGEs/ALEs in(More)
Elevated plasma lipids contribute to neurovascular dysfunction in diabetes. Statins have lipid-lowering properties and can modulate endothelial nitric oxide (NO) bioavailability. The aim was to assess the impact of these factors on autonomic nitrergic nerve and endothelial function. Thus, the effects of diabetes and treatment with the HMG-CoA reductase(More)
Vascular defects contribute substantially to neuropathic changes associated with metabolic abnormalities in diabetes. Statins appear to exert beneficial effects on vascular function independent of cholesterol lowering. In studies of the streptozotocin-induced diabetes rat model, rosuvastatin treatment was shown to correct sciatic motor and saphenous sensory(More)
BACKGROUND AND PURPOSE Semaphorin 3A (Sema3A) is an important secreted repulsive guidance factor for many developing neurones. Sema3A continues to be expressed in adulthood, and expression of its receptor, neuropilin-1 (Nrp-1), can be altered by nerve injury. Autonomic neurones innervating the pelvic viscera are particularly susceptible to damage during(More)
Calpains, a superfamily of Ca(2+)-activated proteases, are associated with an array of physiological and pathological events, including susceptibility to diabetes. Recently, increased calpain activity has been linked to reduced endothelium-derived nitric oxide-mediated vasodilatation in diabetes. However, a similar mechanism for neuronal-derived nitric(More)
Hyperglycaemia in diabetes mellitus results in oxidative stress and pro-inflammatory changes which contribute to vascular complications including endothelial dysfunction and peripheral neuropathy. The aim of this study was to examine whether treatment with the dominant ingredient of clove oil, eugenol, which has antioxidant and anti-inflammatory properties,(More)
AIM Interleukin-6 (IL-6), a member of the neuropoietic cytokine family, participates in neural development and has neurotrophic activity. Recent research has also indicated actions to improve vasa nervorum function in diabetes. Both these facets are potentially relevant for treatment of diabetic neuropathy. The aim of this study was to determine whether(More)
Although older adults have difficulty recognizing all facial emotions, they have particular difficulty decoding expressions of anger. Since disruption of facial mimicry impairs emotion recognition, electromyography of the corrugator supercilii (i.e., brow) muscle region was used to test whether there are age differences in anger mimicry. Associations(More)
Although general emotion coping difficulties are well documented in schizophrenia, there has been limited study of specific regulatory strategies such as suppression, reappraisal, and acceptance. In the present study, clinical and control participants were asked to watch video clips selected to elicit negative affect while engaging in one of these three(More)
