spinal cord injury (sci) results in the damage of motor and sensory pathways. the molecular and cellular structure of the injury milieu has been shown to be vital for endogenous regeneration in most tissues. regeneration of injured central nervous system (cns) is limited by damaged cell environment. biomaterial scaffolds can reconstruct injured cns tissue following sci by promoting the migratio...

it was estimated that 3 million people suffered from spinal cord injury. unfortunately up to date, there are not any reliable clinical treatments for spinal cord injury and researches for treatments of sci have focused on medication, surgery, stem cell transplantation, molecular therapy and tissue engineering. also scientists are trying to use a combination of stem cells and nanotechnology scie...

Surface expression and regulated endocytosis of glycine receptors (GlyRs) play a critical function in balancing neuronal excitability. SUMOylation (SUMO modification) is of critical importance for maintaining neuronal function in the central nervous system. Here we show that activation of kainate receptors (KARs) causes GlyR endocytosis in a calcium- and protein kinase C (PKC)-dependent manner,...

Phasic and tonic inhibitions are two types of inhibitory activities involved in inhibitory processing in the CNS. In the spinal cord dorsal horn, phasic inhibition is mediated by both GABAergic and glycinergic inhibitory postsynaptic currents. In contrast to phasic inhibitory currents, using patch-clamp recording technique on spinal cord slices prepared from adult mice we revealed that tonic in...

A survey of differences in composition and metabolism of myelin from five areas of the central nervous system was made in brain and spinal cord slices of the rat from 20 days to 20 months postnatal age. Purified myelin from the forebrain areas showed a composition characteristic of immaturity longer than did myelin from the hindbrain and spinal cord. The trend of chemical maturity is in agreeme...

a b s t r a c tintroduction: because of more exposure to mercury compounds, the prenatal and postnatal neurotoxic effects of mercury compounds have gained more attention in last decade. the aim of this study was to investigate the effects of mercuric chloride intoxication on spinal cord development during prenatal period. methods: 36 adult sprague-dawley rats after observing vaginal mating plaq...

the overall goal of this study was to identify the appropriate biomaterials able to facilitate the regeneration in rat's injured adult spinal cord. acute damage to axons is manifested as a breach in their membranes, ionexchange distortion across the compromised region, local depolarization and even conduction block. it would be of particular importance to interrupt the progress of events h...

background: spinal cord injury (sci) occurs most often to young men at the peak of their reproductive health. only 10% of sci men can father children without medical assistance due to potential impairments in ejaculation and sperm quality. objective: the main objective of this experimental study was to evaluate the epididymal necrospermia- sperm death, after chronic sci in rat. materials and me...

background: spinal cord injury (sci) stimulates an inflammatory reaction that causes substantial secondary damage inside the injured spinal tissue. the purpose of this study was to determine the anti-inflammatory effects of epigallocatechin gallate (egcg) on traumatized spinal cord. methods: rats were randomly divided into four groups of 12 rats each as follow: sham-operated group, trauma group...

spinal cord injury (sci) leads to a significant health problem associated with a broad range of secondary complications and disabilities. in this regard, animal models can help us to understand the pathobiology of sci and evaluate the effects of potential treatments for sci. in contusion models of sci, different devices including surgical spring-loaded clips, balloons, forceps, weights and the ...
