Efg1 transcription factor is believed to be the main regulator of hyphal formation under many different conditions. In addition, it is responsible for positive regulation of the expression of several hyphal-specific genes. SAP5, which encodes secreted aspartic proteinase, is one of the mentioned genes and is crucial for pathogenicity properties. In the present work we have established the exper...
fold increased risk of developing enterop− athy−associated T−cell lymphoma com− pared with the general population [1]. Early diagnosis is therefore required to improve their prospects. Indigo carmine chromoendoscopy highlights mucosal ir− regularities and improves the detection of malignant lesions [2]. Furthermore, it can delineate villous atrophy in celiac dis− ease [3]. This method is common...
سابقه و هدف: beam shaper نوعی اپلیکاتور مورد استفاده در رادیوتراپی حین عمل توسط الکترون است. هدف از این مطالعه بررسی کمی میزان آلودگی فوتونی ناشی از این اپلیکاتور با استفاده از شبیه سازی مونت کارلو میباشد. مواد و روش ها: در این مطالعه تجربی ابتدا سر شتاب دهنده liac به همراه اپلیکاتور beam shaper توسط کد مونت کارلوی mcnpx شبیه سازی گردید و سپس اعتبار مدل شبیه سازی شده از طریق مقایسه منحنی های د...
BACKGROUND The most important virulence factor which plays a central role in Candida albicans pathogenesis is the ability of this yeast to alternate between unicellular yeast and filamentous hyphal forms. Efg1 protein is thought to be the main positive regulating transcription factor, which is responsible for regulating hyphal-specific gene expression under most conditions. ALS3 is one of the E...
Background and purpose: Beam shaper is a type of applicator used in conjunction with the intraoperative electron radiotherapy. This study aimed at quantitative evaluation of the photon contamination of this applicator using Monte Carlo simulation. Materials and methods: In this experimental study, at first the head of LIAC accelerator was simulated along with the beam shaper applicator using...

Introduction: Intraoperative radiotherapy is a radiotherapy technique in which a high single fraction of radiation dose is delivered to the patient after surgery and Concurrent with anesthesia time. The most frequent method for IORT implementation is Intraoperative electron radiotherapy (IOERT), in which, some dedicated and high dose per pulse electron accelerators are employe...
We read with interest the preliminary report by A. Billaud on omputer-assisted total hip replacement based on EOS imaging ata. As the authors state, hip navigation techniques have improved he reproducibility of implant positioning in hip replacement [1–3]. owever, navigation is at present founded on landmarking in the nterior pelvic plane, for which access in lateral decubitus is diffiult. The ...
Introduction: One of the treatment choices in breast cancer is Intra operative electron beam radiation therapy (IOERT). Due to high dose delivery in this procedure, shielding disk is used to protect organs at risk (OARs). In this study, we evaluate the OARs dose in the breast IOERT using Monte Carlo simulation with and without shielding disk in RANDO phantom. Material and Methods: Simulation ...
