BACKGROUND Myocardial T1 relaxation times have been reported to be markedly abnormal in diverse myocardial pathologies, ascribed to interstitial changes, evaluated by T1 mapping and calculation of extracellular volume (ECV). T1 mapping is sensitive to myocardial water content of both intra- and extracellular in origin, but the effect of intravascular compartment changes on T1 has been largely n...
در این مطالعه مخلوط باسیلوس سابتیلیس (bacillus subtilis) و باسیلوس لیچنی فورمیس (bacillus licheniformis) تجاری و بومی استخراج شده از روده فیل ماهی انگشتقد بر عملکرد رشد، نرخ بقا، ترکیب لاشه، فاکتورهای همولنف، پارامترهای بیوشیمیایی سرم، مقاومت در برابر شرایط محیطی تنشزا و فلور میکروبی روده پستلارو میگوی سفید غربی (litopenaeus vannamei) مورد استفاده قرار گرفت. میانگین وزن پست لاروها 54/6±50 می...
به منظور تعیین زمان آبیاری و اثر تاریخ کاشت بر عملکرد و اجزای عملکرد دانه لوبیاچیتی، آزمایشی در سال 1373 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه صنعتی اصفهان، واقع در روستای شرودان از توابع فلاورجان، به صورت کرت های یک بار خرد شده، در قالب بلوک های کامل تصادفی، و در چهار تکرار اجرا گردید. کرت های اصلی به سه تیمار آبیاری پس از 3± 50، 3± 70 و 3± 90 میلی متر تبخیر از تشت تبخیر کلاس a (تیمارهای t...
The mechanical properties and radiation attenuation competence of Tb3+ ions doped boro-germanate-aluminiophosphate (BGAP) glasses with codes Tb15, Tb20, Tb25, Tb30, Tb35, Tb40 have been investigated. Bond compression model (B–C) Phy-X/PSD software are used to achieve these aims. All elastic moduli were reduced increasing the Tb2O3 content in BGAP glasses. Values bulk (KB–C) modulus possessed de...
PURPOSE The aim of this study was to characterize and compare bacterial diversity on the removable partial denture (RPD) framework over time. MATERIALS AND METHODS This descriptive pilot study included five women who were rehabilitated with free-end mandibular RPD. The biofilm on T-bar clasps were collected 1 week (t1) and 4 months (t2) after the RPD was inserted (t0). Bacterial 16S rDNA was ...
F ocal fibrosis, most due to myocardial infarction, is readily identified by cardiac magnetic resonance (CMR) using widely validated late gadolinium enhancement methods. However, many common conditions of the heart, ranging from hypertrophic cardiomyopathy to idiopathic dilated cardiomyopathy or myocarditis, are histologically characterized by diffuse, interstitial myocardial fibrosis. In these...
A study was conducted to determine irrigation scheduling of pinto bean and to evaluate the effect of its planting date. A split-plot with complete randomized block design with four replications was used at Isfahan University of Technology Research Station in Shervedan-Falavarjan, The main plots were three irrigation regimes of T1 to T3 (irrigation after 50±3, 70±3 and 90±3 mm evaporation from c...
BACKGROUND Magnetic resonance imaging (MRI) has been found to be better than computed tomography for defining the extent of primary gross tumor volume (GTV) in advanced nasopharyngeal cancer. It is routinely applied for target delineation in planning radiotherapy. However, the specific MRI sequences/planes that should be used are unknown. METHODS Twelve patients with nasopharyngeal cancer und...
