INTRODUCTION We hypothesized a relationship between severity of thoracic aortic atheroma (AA) and prevalence of high-risk coronary anatomy (HRCA). MATERIAL AND METHODS We investigated AA diagnosed by transesophageal echocardiography and HRCA diagnosed by coronary angiography in 187 patients. HRCA was defined as ≥ 50% stenosis of the left main coronary artery or significant 3-vessel coronary a...

INTRODUCTION Robot-assisted radical cystectomy (RARC) plus intracorporeal urinary diversion is feasible. Few centers worldwide demonstrated comparable functional and oncologic outcomes. We reported a large series of RARC and intracorporeal diversion to assess its feasibility and reproducibility. MATERIAL AND METHODS We identified 101 RARCs in 82 men and 19 women (mean age 68.3 years) from Oct...

introdouction: mucoepidermoid carcinoma (mec) is one of the most common salivary gland malignancies. the prevalence of salivary gland tumors varies in different geographic areas. in this report, we evaluated the prevalence of mec in iran and compared it with that previously reported in other countries. materials and methods: the files of oral pathology, shahid beheshti university of medical sci...

conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...

Corrosion resistance of pure titanium (Grade 2) and Ti−Pd alloy (Grade 7) was studied using the electrochemical techniques of potentiodynamic measurements and electrochemical impedance spectroscopy (EIS). Measurements were performed at the temperature of 36.6 °C in two solutions: PBS solution with pH of 7.4 simulating conditions of healthy human body, and PBS solution with pH of 5.2 and with th...

Obtaining a continuous source of normal cells or DNA from a single individual has always been a rate limiting step in biomedical research. Availability of Lymphoblastoid cell lines (LCLs) as a surrogate for isolated or cryopreserved peripheral blood lymphocytes has substantially accelerated the process of biological investigations. LCLs can be established by in vitro infection of resting B cell...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

To explore the expression pattern, prognostic value and functional role of stromal periostin (POSTN) in glioma patients, POSTN expression was measured using the Agilent Whole Human Genome Oligo Microarray in 220 frozen glioma tissues. We analyzed POSTN expression in 71 independent validated glioma samples using immuno-histochemistry. The expression levels of POSTN were relative to glioma grade ...

in this study, the response is derived, high-energy material 1-(4-nitrophenyl)-1h-tetrazole (npht) with boron nitridenano-cages in different conditions of temperature, density functional theory methods were studied. for this purpose, the material on both sides were geometrically optimized, then the calculation of the thermodynamic parameters were performed on all of them. the amount of δh, δs a...
