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...

objective: diabetes mellitus is one of the most common medical problems worldwide. approximately 18% of persons over 65 years old are diabetic. who estimates that the prevalence rate of diabetes (4% in 1995) will increase to 5.6% in 2025. diabetic foot problems are potentially the most preventable long–term complication for diabetes. the purpose of this study was to test the utility of the heal...
BACKGROUND Liver stiffness measurement (LSM) has recently become available for assessment of liver fibrosis. We aimed to develop a prediction model for liver fibrosis using clinical variables, including LSM. METHODS We performed a prospective study to compare liver fibrosis grade with fibrosis score. LSM was measured using magnetic resonance elastography in 184 patients that underwent liver r...
OBJECTIVES To demonstrate the feasibility of a novel fractional motion (FM) diffusion model for distinguishing low- versus high-grade pediatric brain tumors; and to investigate its possible advantage over apparent diffusion coefficient (ADC) and/or a previously reported continuous-time random-walk (CTRW) diffusion model. MATERIALS AND METHODS With approval from the institutional review board ...
Background and Aim: Anemia caused by iron deficiency, an important health issue is especially in teenager girls. The purpose of this study was, to determine the application of the Health Belief Model (HBM) constructs for the identification of influential factors on iron supplementation consumption among 9 th-grade female students in Birjand. Materials and Methods: This descriptive-analytical c...
It is shown that application of the Rasch model for equating grades at Basic and Higher Level of Mathematics at General Matura exam in [Hauptman, Metodološki zvezki 7 (2010) 167-181.] is not justified.
Due to uncertain nature of grade in ore deposits, considering uncertainty is inevitable in geological modelling of resources and mine planning. In other words, uncertainty in grade of mineralized materials, is one of the most significant parameters need attention in mine planning. In this paper, a comparative procedure utilizing Sequential Gaussian Simulation (SGS) and traditional Ordinary Krig...
The aim of this research is to study the components of creativity in elementary school curricula. The research method used in this research is content analysis. The information source of this research is the 6th Grade Mathematics textbook in the academic year 1391-92. To achieve face validity, the viewpoints of the educationalists and experts were used in this research, and to achieve reliabili...
پنل های خورشییدی دارای مشیه ه جریان -ولتاژ غیر خطی بوده و تنها در یک نقطه کار خاص، حداکثر توان را تولید می کنند. این نقطه بهینه توان با تغییر دما و شیدت نور تغییر می کند. روش های مهتلفی برای ردیابی نقطه حداکثر توان به صورت free model و based model معرفی شده است. این تحقیق روش جدیدی جهت بهبود عملکرد ردیابی نقطه حداکثر توان پنل های خورشیدی جدا از شبکه ارائه می دهد و الگوریتم روش پیشینهادی از دو...
