aims: the aim of the present work is (1) to evaluate dose calculation accuracy of two commonly used algorithms for 15 mv small photon fields in a medium encompassing heterogeneity and (2) compare these results with measured results obtained using gafchromic film ebt2. materials and methods: authors employed kailwood (pinus wallichiana) to mimic lung. briefly, seven kailwood plates, each measuri...
BACKGROUND AND AIMS Chronic kidney disease (CKD) and diabetes mellitus (DM) are considered as risk factors for cardiovascular diseases. The purpose of this study was to clarify the relationship of CKD and DM with the presence of abdominal aortic aneurysm (AAA). METHODS We enrolled 261 patients with AAA (AAA+) and age-and-sex matched 261 patients without AAA (AAA-) at two hospitals between 200...
ماده ی مورد بحث در این مقاله یا AAA یا آزولای فعال حاصله، از طریق 10 سال پژوهش در جهت بهبود عملکرد انرژی و کاهش مصرف سوخت های فســیلی عــملی شده است. درواقــع، این محــصول حاصــل تلاش پی گــیر تحقیقی در استفاده از انرژی خام موجود در مواد ارگانیک و کاهش درگاشت در اکوسیستمها بوده که منجر به تولید فراوری شده، از گیاه آزولا با نام علمی سرخس آبزی موجود در تالاب انزلی و مواد ارگانیک گردیده و اثرات آ...

Abdominal aortic aneurysm (AAA) is the most common and critical disease. Bleeding serious complication from a ruptured AAA, which often results in death. Therefore, early diagnosis treatment are only effective means to reduce AAA associated mortality. Positron emission tomography/computed tomography (PET/CT) combines functional anatomical imaging. The expanded application of PET/CT medical fiel...
