Background & Aim: Various landmarks are discussed to find the facial nerve during parotid surgery. The surgeon should use existing landmarks for a safe surgical use. To evaluate two new landmarks in parotid surgery, this study was done. Methods & Materials/Patients: This cross-sectional study was conducted on 43 patients with parotid masses, whom were referred to Alzahra and Kashani tertiary...
Objective: in the evaluation of peripheral nerves, upper limb neurodynamic tests are used to assess the mechanical sensitivity of the nerve. However, very little is known about the reliability of upper limb neurodynamic tests, especially for the radial and ulnar nerves. The aim of this study was to evaluate the reliability of neurodynamic tests of the upper extremities including median, radial ...
Background and Objective: Approximately 45% of benign peripheral nerve sheath tumors (PNST) occur in head and neck regions. Malignant peripheral nerve sheath tumors (MPNST) are less common and only 8-15% of these tumors occur in head and neck region. In this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family h...
After peripheral nerve injury, Wallerian degeneration (WD) occurs in the distal nerve segment. During the process of degeneration, Schwann cells (SCs) dedifferentiate, proliferate and migrate to align in "bands of Büngner", providing structural guidance and growth-promoting substrates to regenerating axons. The molecular signals that trigger SCs migration remain unclear. Here, we explored the m...
the purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and dna damage). semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. five healthy buffalo bulls (5 ejaculates from ...
Abstract Neurofibromatosis type 1 (NF1) is an autosomal dominant tumor predisposition syndrome that is caused through loss of function mutations of a tumor suppressor gene termed neurofibromin 1. Therapeutic decisions are presently restricted for NF1-associated tumors, where treatment is often restricted to thorough surgical resection with perfect margins. In this review article, the multif...
Effect of alcoholic and aqueous extracts of the fruits of F. racemosa Linn., on the spontaneous movements of both the whole worm and nerve muscle preparation of Setaria cervi and on the survival of microfilariae in vitro was studied. Alcoholic as well as aqueous extracts caused inhibition of spontaneous motility of whole worm and nerve muscle preparation of Setaria cervi characterized by increa...
Entrapment of median nerve can be developed at multiple sites along this nerve. One of the compression sites of median nerve is supracondylar area of humerous. Sometimes struther ligament or spur or both of them are the rare cause of entrapment syndrome of the median nerve. Struther ligament or spur can compress ulnar nerve and/or brachial artery. These cases may have median ulnar ner...
OBJECTIVE Delayed gastric emptying and/or gastrointestinal symptoms occur in 30-50% of diabetic patients. Known contributing factors are autonomic neuropathy and acute hyperglycemia, but the role of gastric autoimmunity has never been investigated, although 15-20% of type 1 diabetic patients exhibit parietal cell antibodies (PCAs). We studied gastric motility in diabetes in relation to PCA stat...
SUMMARY The term opioid was coined to refer in a generic sense to all drugs, natural and synthetic, with morphin - like actions. Three distinct families of peptides have been identified so far in gastrointestinal (GI) nervous system in mammalian. These peptides include : dynorphin, Met - enkephalin and leu - enkephalin . Results from studies about opioid which have been started 15 years ago ...
