Background: Osteoporotic compression vertebral fractures are common clinical problems. In those with refractory fractures, percutaneous cement augmentation has been suggested. The aim of this study was to evaluate the functional outcome of percutaneous vertebroplasty in Iranian patients with refractory osteoporotic fractures. Methods: We retrospectively studied 37 osteoporotic fractures in 28 p...
between 1371 to 1379, of 10 patients with radial tunnel syndrome, 9 patients were treated by decompression of the posterior interosseous nerve. 8 patients were followed up more than 10 months. one patient improved without surgery. half of the patients suffered from pain and all of them had variable degrees of paralysis in muscles innervated by deep branch of the radial nerve. the syndrome was d...
since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–d realization. although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. in this paper, first a method is proposed to extract th...
physicochemical and mechanical properties of wheat grains can have a great impact on the quality of the final products (bread). therefore, correct selection of wheat cultivar for specific applications seems to be crucial. in this study, the differences in the physicochemical and mechanical properties (under compression and impact loadings) of ten iranian wheat cultivars (azar2, alamut, bam, bah...
the exergy analysis is a proper method for performance evaluation of industrial systems. a generic and detailed analysis of the gpcss on the second gas pipeline of iran is made by the means of exergy. the two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. steady state equations regarding the second law of ther...
Background and Aim: Peripheral nerve injury occurs in about 3% of the patients suffering from trauma and accidents. This injury induces Wallerian degeneration in the site of injury and, as a retrograde reaction, extends to the cell bodies of injured neurons in the central nervous system. The present study aimed to assess the neuro-protective effects of the alcoholic extract of Artemisia herba-a...
