The outer hair cell (OHC) is known to have the ability to change its length in response to voltage changes across its membrane. The apparent function of this OHC motility is to enhance the tuning of the basilar membrane. The model presented in this paper represents the displacement-to-voltage and voltage-to-displacement transducers of the OHC explicitly, each as low-pass filter functions. The m...

Immunocytochemistry and in vitro studies have suggested that the ERM (ezrin-radixin-moesin) protein, radixin, may have a role in nerve growth cone motility. We tested the in situ role of radixin in chick dorsal root ganglion growth cones by observing the effects of its localized and acute inactivation. Microscale chromophore-assisted laser inactivation (micro-CALI) of radixin in growth cones ca...

introduction: epineural suture and autologous graft are two routine techniques in peripheral nerve surgery. however, their efficiency can be highly limited depending on the type of lesion and the gap between two nerve stumps and because of deficient proper nerve donors. so much interest has been focused on the development of alternative instruments for bridging the nerve gaps. in the present st...

purpose: to compare complications and motility of hydroxyapatite versus medpor ocular implants after enucleation at ahvaz imam hospital (from jan 2010 to jun 2011). methods: in a clinical trial, 50 patients scheduled for enucleation were randomly divided in two groups of 25 patients. group 1 underwent enucleation + hydroxyapatite (ha) and group 2 underwent enucleation + medor implant. all patie...

Atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. The present report describes a case of variation of the median nerve observed in the Iranian male cadaver during routine trial dissection. There are three roots for median nerve. Median nerve is formed by joining two lateral and medial cords of brachial plexus. Third root ...

background and importance: our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. in cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. case presentation: representation of two complex...

During selective proximal vagotomy (SPV), atypical SPV (atyp-SPV) was proposed when either the anterior or posterior nerve of Latarjet was sacrified. In order to study the gastric motility after atyp-SPV , eight mongrel dogs on which SPV had been performed underwent atyp-SPV, with subsequent transthoracic truncal vagotomy (TV). These surgeries were performed at about 4 to 5 week intervals, and ...

The stomach is the segment of the gastrointestinal tract in which the main secretory functions and digestion in the alimentary canal begins. However, it’s most critical and important function in digestive physiology is gastric motility (GM). Normal GM is controlled by diverse extrinsic and intrinsic stimuli. The main extrinsic regulation comes from the vagal nerve. Although the majority of vaga...
