A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. the safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...

background and objectives: multiple sclerosis (ms) is the most common demyelinating disease of the central nervous system with more than 5.2 million people across the world being afflicted with. magnetic resonance im­aging (mri) is a valuable tool in the diagnosis of ms. this study surveys the results of mri of the central nervous system and paranasal sinuses in the sample of ms patients in ker...

developmental venous anomaly (dva) is a common lesion formerly known as venous angioma. dvas drain normal brain parenchyma; however, parenchymal abnormalities surrounding dvas have been reported. unilateral putamen and caudate calcification in the drainage territory of dvas has so far been reported in 7 cases, all with deep venous drainage. we present two additional cases of dvas, one with supe...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...
