Degeneration of the intervertebral disc, sometimes associated with low back pain and abnormal spinal motions, represents a major health issue with high costs. A non-invasive degeneration assessment via qualitative or quantitative MRI (magnetic resonance imaging) is possible, yet, no relation between mechanical properties and T2 maps of the intervertebral disc (IVD) has been considered, albeit T...

INTRODUCTION Low back pain is a major economical and social problem nowadays. Intervertebral disc herniation and central degeneration of disc are two major reasons of low back pain that occur because of structural impairment of disc. The intervertebral disc contains three parts as follows : Annulus fibrosus, transitional region, and nucleus pulposus, which forms the central nucleus of the disc....

Approximately 2.6 % of the US population visits a physician for treatment of spinal disorders annually (Fraser 2009 ) with costs of $7.1 billion from lost work days alone (Ricci et al. 2006 ) . “Herniation” of the intervertebral disc is one of the several spinal disorders that contribute to this very high incidence, with potential to cause signi fi cant pain, neurological de fi cit, and functio...

Intervertebral disc (IVD) degeneration is a chronic pathologic process characterized by excessive apoptosis of intervertebral disc cells. The purpose of the current study was to detect the effect of integrin β1 on apoptosis of NP cells and IVD degeneration. Integrin β1 overexpressing lentivirus vector (LV-ITG β1) was constructed and transduced to NP cells, and its effect on cell apoptosis were ...

Degeneration of the lumbar intervertebral disc is most common cause lower back pain. It directly related to daily activities, mechanical stress, and other biological factors. We use imaging modalities assess degree degeneration, out which magnetic resonance (MRI) popular non-invasive modality. believed that early changes in degeneration are due biochemical events can be evaluated by sequences M...

The aim of the study was to investigate the mechanism of microRNA (miR)-146a-mediated activation of interleukin-6/signal transducer and activator of transcription 3 (IL-6/STAT3) in lumbar intervertebral disc degeneration. To obtain intervertebral tissue, we recruited 5 patients with lumbar intervertebral disc herniation (experimental group) and 5 patients with lumbar burst fracture (control gro...

Interleukin-17 (IL-17) is a cytokine recently shown to be elevated, along with interferon-γ (IFNγ) and tumor necrosis factor (TNFα), in degenerated and herniated intervertebral disc (IVD) tissues, suggesting a role for these cytokines in intervertebral disc disease. The objective of our study was to investigate the involvement of IL-17 and costimulants IFNγ and TNFα in intervertebral disc patho...

OBJECTIVE Follistatin-like protein 1 (FSTL1) is a well-known mediator of inflammation. Intervertebral disc disease is an inflammatory disorder. Here, we investigated the role of FSTL1 in the intervertebral discs inflammation. METHODS Expression of FSTL1 in nucleus pulposus tissues from rats and human was determined by immunohistochemistry staining and western blot analysis. The expression lev...
