Case reports of patients with mal-functioning metal-on-metal hip replacement (MoMHR) prostheses suggest an association of elevated circulating metal levels with visual and auditory dysfunction. However, it is unknown if this is a cumulative exposure effect and the impact of prolonged low level exposure, relevant to the majority of patients with a well-functioning prosthesis, has not been studie...

the finite element method (fem) is one of advanced methods in modeling of solid mechanics used in the design and analyzing of prosthesis in the human body. one of the important factors in designing a femur (the linkage between basin and knee) which is under complicated stresses is to minimize the amount of the stress in the components of the prosthesis due to the body weight. in this research t...

The decision of whether to perform cochlear implantation is crucial because cannot be reversed without harm. aim the study was compare model-predicted time–place representations auditory nerve (AN) firing rates for normal hearing and impaired with a view towards personalized indication implantation. AN 1024 virtual subjects wide variety different types degrees impairment were predicted. A refer...

background and aim: auditory processing disorders may have detrimental consequences on a child’s life, if undiagnosed and untreated. the multiple auditory processing assessment (mapa), as a valid model, has been introduced for central auditory processing assessment and diagnosis in school children. the purpose of this study was to design and evaluate the persian version of mapa for auditory pro...

Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...
