Background: Spinal cord has a limited capacity to repair therefore, medical interventions are necessary for treatment of injuries. Transplantation of Schwann cells has shown a great promising result for spinal cord injury (SCI). However, harvesting Schwann cell has been limited due to donor morbidity and limited expansion capacity. Furthermore, accessible sources such as bone marrow stem cells ...

background: recent reports demonstrated that intravenous route as a minimally invasive method, similar to direct injection, is suitable for bone marrow stromal cell (bmsc) transplantation. in this study, we made a comparison of intraspinal and intravenous route of bmsc administration to repair injured spinal cord tissue. methods: six groups of adult female rats were used in this study. laminect...

Aberrant calpain activation is a key mediator of neuron death. We examined the cell-permeable calpain inhibitor MDL28170 in the pathophysiological processes after spinal cord injury (SCI) including p35-p25- cyclin-dependent kinase-5 (Cdk5) activation, tau hyperphosphorylation, neuron cell death, calpain I activation, astrogliosis, and microglia activation. Our study showed that intrathecal admi...

Spinal cord injury (SCI) can induce remodeling of multiple levels of the cerebral cortex system especially in the sensory cortex. The aim of this study was to assess, in vivo and bilaterally, the remodeling of dendritic spines in the hindlimb representation of the sensory cortex after spinal cord hemisection. Thy1-YFP transgenic mice were randomly divided into the control group and the SCI grou...

a high number of people in the world suffered from spinal cord injury (sci). spinal cord injuries are happen due to falls from height, accidents, climbing, sports and etc. emergency care according to the standards not performed immediately after sci. a significant enhancement in the number of mortality and complications was observed every year. the aim of this study is to prevent the mortality,...

Clinical evidence indicates that motor training facilitates functional recovery after a spinal cord injury (SCI). Brain-derived neurotrophic factor (BDNF) is a powerful synaptic facilitator and likely plays a key role in motor and sensory functions. Spinal cord hemisection decreases the levels of BDNF below the injury site, and exercise can counteract this decrease [Ying Z, Roy RR, Edgerton VR,...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...

After an incomplete spinal cord injury (SCI), partial recovery of locomotion is accomplished with time. Previous studies have established a functional link between extension of axon collaterals from spared spinal tracts and locomotor recovery after SCI, but the tissular signals triggering collateral sprouting have not been identified. Here, we investigated whether axonal degeneration after SCI ...

Spinal cord injury (SCI) is a major cause of disability for many living persons. Therefore, several experimental models and handful of techniques were developed to study and characterize the damage evolution following SCI. In the present study, high b-value q-space diffusion-weighted imaging (DWI) was used to follow the spatial and temporal damage evolution in excised rat spinal cords following...
