Cancer patients with spinal metastases are a diagnostic and treatment challenge for the clinician. This challenge must be addressed through a multidisciplinary, multimodal, and individualized management. The presence of tumor cells in bone metastases results in homeostatic disruption between bone formation and remodeling. Bone destruction is a late event in the formation of lytic bone metastasi...

to date, various approaches have been used in attempt to treat spinal cord injury (sci) but there is no definite treatment for repair of the damaged tissue. it is well known that sci results in a loss of neural tissues and formation of cystic cavities that inhibit regeneration of axons. tissue engineering, in which cells, signals and scaffolds are combined, is one of the most promising areas of...

although spinal cord injury (sci) is one of the most common injuries after a road accident, there is no definite treatment for it. in this regard, nanotechnology has focused to retrieve damaged tissue function by designing of a biomaterial as a mimicking extracellular matrix to reduce inflammation, scar and lactate dehydrogenase, to fill the cyst and improve the graft integration, cell prolifer...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

introduction spinal cord injury without radiological abnormality (sciwora) is a rare entity and usually involves the cervical spine. thoracic spine involvement is very rare due to the stability provided by the rib cage. the mechanisms of injury and pathophysiology are still debatable. case presentation we present a case of an adult male who had road traffic accident and presented with paraplegi...

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...

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...
