background: acinetobacter baumannii is an opportunistic and gram-negative coccobacillus. this opportunistic pathogen infectivity, especially in the intensive care units of hospitals is extensive worldwide. due to the incremental pattern of antibiotic resistance, this study was carried out to track the class i, ii and iii integrons in acinetobacter baumannii isolated from hospitalized cases in m...
background and objective: neuroendocrine differentiation has not been proved to have effects in behavior of colorectal carcinomas. the aim of this study was immunohistochemical evaluation of neuroendocrine differentiation in colorectal cancer. patients and methods: in this cross-sectional study, 83 paraffin blocks from patients admitted in rasoul-e-akram hospital, tehran, iran, during 2003 to 2...
The present paper is concerned with the investigation of disturbances in a homogeneous transversely isotropic thermoelastic rotating medium with two temperatures, in the presence of the combined effects of Hall currents and magnetic field due to thermomechanical sources. The formulation is applied to the thermoelasticity theories developed by Green-Naghdi Theories of Type-II and Type-III. ...
background and aims: p504s (amacr) is a mitochondrial enzyme expressed in renal cell carcinoma. some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. amacr expression increases with higher histological grading in different tumors; however, in rcc it is not obvious. in this study, we tried to investigate if any relat...

Purpose: The limited availability of donor sites for nerve grafts continues to stimulate research toward finding suitable alternatives. Material and Methods: In the following study, the effects of direct administration of Nerve Growth Factor (NGF), Insulin - Like Growth Factor - I (IGF-I) , or / and collagen gel into Polyvinylidene Fluride (PVDF) gap was tested in a rat sciatic nerve model. A ...
در این پروژه لیگاند باز شیف مشتق شده از واکنش 2-هیدروکسی-3-متوکسی بنزآلدهید با 1 و 2- بیس (2-آمینو تیو فنیل)اتان با نسبت مولی 2 به 1 در حلال اتانول تهیه شد. سپس کمپلکس های آهن(iii)، کبالت(ii) و مس (ii)این لیگاند باز شیف نیز سنتز شد. شناسایی این لیگاند و کمپلکس های آن به کمک آنالیز هدایت سنجی، طیف بینی های ir، 1h-nmr و 13c-nmrو طیف جرمی انجام گرفت. این لیگاند باز شیف شش دندانه از طریق اتم های o،...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
