background: headache is one of the most disturbing symptoms with common neurological signs. variations in optic nerve perfusion quality or retinal microcirculation may end up in ganglion cell damage in patients with migraine. methods: sixty patients diagnosed with migraine and thirty normal individuals were evaluated in groups including migraine with aura, migraine without aura and controls. re...

introduction: median nerve (mn), one of terminal branches of brachial plexus, is commonly associated with several variations. this research aimed to review the literature related to the variations of mn from axillary region to cubital fossa. methods: we searched google scholar, science direct, springer, and pubmed electronic databases to compile reports related to the variation of mn published ...

objective(s):  the aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (esm) tube conduit in comparison with autograft. materials and methods: thirty adult male rats (250-300 g) were randomized into (1) esm conduit, (2) autograft, and (3) sham surgery groups. the eggs submerged in 5% acetic acid. the decalcifying membranes were cut into four pie...

The interstitial cell (i-cell) of hydra, a multipotent stem cell, produces two classes of differentiated cell types, nerve cells and nematocytes, throughout asexual growth. Using a new assay, the regulation of i-cell commitment to either nerve cell or nematocyte differentiation was investigated. This assay was used to determine the fractions of i-cells differentiating into nerve cells and nemat...

Optical coherence tomography (OCT) is considered a key research tool to monitor neurodegenerative processes in CNS disorders. This particularly applicable multiple sclerosis (MS), which retinal changes (peripapillary nerve fiber layer and ganglion cell–inner plexiform [GCIPL] thicknesses) tend reflect MRI markers of damage atrophy, especially eyes not affected by previous optic neuritis.1

background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...

several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...
