Background & Aims: In addition to the clinical and histological factors that are able to differentiate between low grade tumors and high grade tumors in bladder urothelial tumors, a number of biomarkers have also been proposed that may be useful in evaluating tumor grade, outcome, and prognosis. The purpose of the present study was to investigate the relationship between the amount of Her2/neu ...
Introduction: The most common primary tumors of brain are gliomas and tumor grading is essential for designing proper treatment strategies. The gold standard choice to determine grade of glial tumor is biopsy which is an invasive method. The purpose of this study was to investigatethe role of fiber density index (FDi) by means of diffusion tensor imaging (DTI) (as a noninvasive method) in glial...
background : cd117 is a thyrosin kinase receptor encoded by c-kit proto-oncogene. it is expressed during normal development in some tissues and also in a subset of neoplasia especially gastrointestinal stromal tumors (gists). treatment with thyrosin kinase inhibitors (e.g., imatinib) is useful in cd117- positive gists. the goal of this study is to investigate the expression of cd117 in glial ...
Background: Recently the use of “two tier" grading system in which ovarian serous carcinoma was classified as low-grade or high-grade in comparing to preceding system has improved authority in prognosis and survival. This approach is simplistic, reproducible, and based on biologic evidence. In this study, we reclassified ovarian serous carcinoma by a new two-tier system for grading and then eva...
background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...
objective: gliomas are the most common primary brain tumors, and have been ranked as the fourth leading cause of cancer death. tumor mesenchymal-like stem cells (tmscs) contribute to the aggressive behavior of glial tumors by providing a favorable microenvironment for the malignant cells. the aims of our study were to identify differential proteome of tmscs derived from low vs. high grade gliom...
ABSTRACT Bladder cancer consists of about 5.2% of all cancers in men and 2.3% in women. About 90% of them have the origin of transitional cells(TCC). There are some predictive factors that knowledge of them is useful for management and follow-up of the patients. Expression of oncoprotein P53 is one of these factors. Considering influence of P53 expression on prognosis, we decided ...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
abstract background: squamous cell carcinoma (scc) constitutes the main oral malignancy . parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as epidermal growth factor (egf) and laminin-5 are sought to estimate macroscopic and microscopic tumor status . methods: we conducted a cross-sectional study collecting ...
Background & Aims: The use of curettage in the diagnosis of endometrial disorders is very widespread, and is the most common diagnostic method before performing hysterectomy. Various studies have been performed to compare the pathological results obtained from curettage with the final pathological results of hysterectomy. The results of some of these studies indicated high efficiency of curetta...
