Human mesenchymal stem cells isolated from Wharton's jelly of the umbilical cord were induced to transform into dopaminergic neurons in vitro through stepwise culturing in neuron-conditioned medium, sonic hedgehog, and FGF8. The success rate was 12.7%, as characterized by positive staining for tyrosine hydroxylase (TH), the rate-limiting catecholaminergic(More)
BACKGROUND Human umbilical mesenchymal stem cells (HUMSCs) isolated from Wharton's jelly of the umbilical cord can be easily obtained and processed compared with embryonic or bone marrow stem cells. These cells may be a valuable source in the repair of spinal cord injury. METHODOLOGY/PRINCIPAL FINDINGS We examine the effects of HUMSC transplantation after(More)
Previous studies have established the neurotoxicity and pathology of acrylamide to large-diameter nerves. It remains unclear (1) whether small-diameter sensory nerves are vulnerable to acrylamide and (2) if so, how the pathology evolves during intoxication. We investigated the influence of acrylamide on small-diameter sensory nerves by studying the(More)
Hyperglycemia is a well-known factor in reducing nocturnal pineal melatonin production. However, the mechanism underlying diabetes-induced insufficiency of pineal melatonin has remained uncertain. This study was undertaken to examine the structure, innervation and functional activity of the pineal gland in streptozotocin (STZ)-induced diabetes in rats by(More)
Nerve decompression is an important therapeutic strategy to relieve neuropathic pain and promote the peripheral nerve regeneration. To address these issues, we investigated the effects of nerve decompression on relief of neuropathic pain behaviors, redistribution of voltage-gated sodium channels (VGSCs), and skin reinnervation with chronic constriction(More)
Paclitaxel in chemotherapy-induced peripheral neuropathy (CIPN) is predominantly with a dose-limiting effect on neuropathic pain in clinical strategy. In the present study, the relationship between the neuropathic pain and nerve degeneration in paclitaxel CIPN was investigated. Adult male Sprague-Dawley (SD) rats were divided into three paclitaxel groups(More)
Wallerian degeneration or nerve demyelination, arising from spinal nerve compression, is thought to bring on chronic neuropathic pain. The widely distributed metabotropic glutamate receptor subtype 5 (mGluR5) is involved in modulating nociceptive transmission. The purpose of this study was to investigate the potential effects of mGluR5 on peripheral(More)
Previously, we showed improved shelf life for agrobacterial isopentenyltransferase (ipt) transgenic broccoli (Brassica oleracea var. italica), with yield comparable to commercial varieties, because of the protection mechanism offered by molecular chaperones and stress-related proteins. Here, we used proximate analysis to examine macronutrients, chemical and(More)
BACKGROUND Spared nerve injury is an important neuropathic pain model for investigating the role of intact primary afferents in the skin on pain hypersensitivity. However, potential cellular mechanisms remain poorly understood. In phosphoinositide-3 kinase pathway, pyruvate dehydrogenase kinase 1 (PDK1) participates in the regulation of neuronal plasticity(More)
The authors examined the role of nitric oxide (NO) in the relationship between kainate-induced neuronal death and locomotion changes. Locomotion was significantly increased 1 h after kainate injection, suggesting that kainate induced NO and dopamine release. Cell death occurred in the CA1 (41%) and CA3 (54%) regions at 12 h. At 7 days, GABAergic neurons in(More)
