In microsurgical nerve repair, the epineural sleeve technique can be used to bridge short nerve defects and to coverthe coaptation site with the epineurium of the nerve stump. The epineurium serves as a mechanical aid to reducegap size, and increase repair strength, effectively assisting nerve regeneration.This article presents a 32-year-old patient who experienced complete transection of the m...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

Autograft is gold standard treatment for peripheral nerve repair up to now. Eggshell membrane (ESM) as nerve guide channel effectively enhances nerve regeneration. Dimethyl sulphoxide (DMSO) has anti-inflammatory and anti-oxidant properties. The aim of this study was to evaluate the effect of DMSO+eggshell membrane guide channel on sciatic nerve regeneration in rats. Thirty two adult male rats ...

PURPOSE To investigate relationships between acute intraocular pressure (IOP)-induced optic nerve head surface deformation and corneal hysteresis and thickness in glaucomatous and nonglaucomatous human eyes. METHODS This was a prospective experimental study of 100 subjects (38 with glaucoma, 62 without glaucoma). Data collected included spherical equivalent, optic disc diameter, central corne...

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

superplastic materials show a very high ductility. this is due to both peculiar process conditions and material intrinsic characteristics. however, a number of superplastic materials are subjected to cavitation during superplastic deformation. evidently, extensive cavitation imposes significant limitations on their commercial application. the deformation and failure of superplastic sheet metals...

this study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a trip steel with a high content of al and a low content of si. to the aim, appropriate treatments were used to produce the starting material (trip steel). the microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...
