The aim of this work is to evaluate the performance of a commercial brachytherapy treatment planning system (TPS) with TG-43 Vendors Input Data (VID), analyze possible discrepancies with respect to a proper reference source and its implications for standard treatments, and judge the effectiveness of certain widespread recommended quality controls to find potential errors related with the interp...

Although the rate of blastocysts implantation of embryos is higher than previous stages but their survival rate is lower than them, which could be attributed to the completely filled blastocoel cavity with liquid and increased possibility of the formation of ice crystals. This liquid could prevent the penetration of cryoprotecting materials into the embryos. In this study, we reduced the volume...

INTRODUCTION Serum prostate specific antigen (PSA) concentration in localized prostate cancer (PCa) patients depends of numerous factors related to tumor, prostate and the patient. Tumor factors include tumor volume, localization, growth rate and aggressiveness. Prostate factors include prostate volume, the activity of dihydrotestosterone (DHT) and PSA synthesis. Host factors include androgenic...

Artificial tissue growth requires cells to proliferate and differentiate within the host scaffold. As cell function is governed by mechano-sensitive selection, tissue type is influenced by the microscopic forces exposed to the cells, which is a product of macroscopically straining the scaffold. Accordingly, the microscopic strain environment within a CG scaffold is offered here. Using muCT to c...

PURPOSE To assess the clinical utility of the prostate-specific antigen mass ratio (PSA- MR), a newly developed PSA derivative, simply defined as the (i) PSA density (PSA-D) multiplied by the plasma volume or (ii) total PSA amount in circulation per prostate volume, for predicting prostate cancer (PCa) among men undergoing repeated prostate biopsy (PBx). MATERIALS AND METHODS Patients (n = 28...

Partial transmission through rounded leaf ends of Varian multileaf collimators (MLC) is accounted for with a parameter called the dosimetric leaf gap (DLG). Verification of the value of the DLG is needed when the dose delivery is accompanied by gantry rotation in VMAT plans. We compared the doses measured with GAFCHROMIC film and an ionization chamber to treatment planning system (TPS) calculat...

Disposition and transportation of anticancer drugs by human serum albumin (HSA) affects their bioavailability, distribution and elimination. In this study, the interaction of a set of anticancer drugs with HSA was investigated by molecular dynamics and molecular docking simulations. The drugs' activities were analyzed according to their docking scores, binding sites and structural descriptors. ...

Background and Objectives: Flat breads are the most consumed bread in Iran. Barbari one of the popular ones, is traditional flat leavened Iranian bread and one of the most popular breads consumed in Iran and some other countries in the Middle East. Materials and Methods: The aim of this study was to evaluate the effect of substitution of wheat flour by whole quinoa flour (0-15% substitution) a...
