Nerve cell differentiation in the polyp Hydra is strikingly patterned: head and basal disk contain high densities of nerve cells. The pattern is formed by migration of interstitial cell precursors from the gastric region to sites of nerve cell differentiation in the head and basal disk. Migration occurs early in the final cell cycle of precursors and appears to be coincident with commitment to ...

introduction: injury to cranial nerves ix, x, and xii is a known complication of laryngoscopy and intubation. here we present a patient with concurrent hypoglossal and recurrent laryngeal nerve paralysis after rhinoplasty. case report: the patient was a 27-year-old woman who was candidate for rhinoplastic surgery. the next morning after the operation, the patient complained of dysphonia and a s...

background: the standard method for repair of an injured peripheal nerve is epineural repair with separate sutures. herein we describe a method in which the nerve is sutured with continous sutures. in fact this method has not been utilized for nerve repair previously and our purpose was to compare it to the standard method. if it proved to be successful it would replace the standard method in c...

Strategies involving the inclusion of cell-instructive chemical and topographical cues to smart biomaterials in combination with a suitable physical stimulus may be beneficial enhance nerve-regeneration rate. In this regard, we investigated surface functionalization poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV)-based electroconductive electrospun nanofibers coupled externa...

Backgrounds: To evaluate changes in the thickness of ganglion cell-inner plexiform layer and macular retinal nerve fiber using ocular coherence tomography patients exposed to hydroxychloroquine .
 Methods: This was a retrospective, cross-sectional study on therapy. Ocular images showing cell were obtained compared controls. The relationship between layer, duration cumulative dose evaluated...

Myelin-associated glycoprotein (MAG) binds to the nerve cell surface and inhibits nerve regeneration. The nerve cell surface ligand(s) for MAG are not established, although sialic acid-bearing glycans have been implicated. We identify the nerve cell surface gangliosides GD1a and GT1b as specific functional ligands for MAG-mediated inhibition of neurite outgrowth from primary rat cerebellar gran...

during the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. during routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. in this case, the superior root of the a...

introduction: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can increase axonal regeneration in peripheral nerve injuries. based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . we pursued to evaluate the effects of bmscs and scs co-transplant...

Dissection of the cavernous nerves during radical prostatectomy for prostate cancer eliminates spontaneous erections. Using the rat as an experimental model, we compared the regenerative capacity of autologous nerve grafts and Schwann-cell-seeded nerve guides. After bilateral excision of cavernous nerve segments, cavernous nerves were reconstructed using unseeded silicon tubes, nerve autografts...
