Methods 10 Sprague Dawley rats (female, 250-300g) underwent ligation of the left anterior descending or circumflex coronary arteries for 60 minutes, followed by reperfusion for 48 hours. The rats were then scanned at 7.0T MR (BRUKER BIOSPEC 70/30, Germany), using T2 mapping(TR/ TE=1500ms/10,20,30ms, MTX=192×192, FOV=50×50mm, slice thickness=1.5mm) and LGE(TR/TE=5.2ms/1.8ms, FA=25°, MTX=256×256,...
We sought to distinguish area at risk from salvage myocardial zone and predict left ventricle functional recovery in the convalescent stage by Texture Analysis (TA) of T2−Mapping. One hundred six patients diagnosed with AMI treated percutaneous coronary intervention (PCI) underwent acute cardiac magnetic resonance imaging (CMR) 45 whom had a subsequent CMR scan following recovery. Cine imaging,...
چکیده: گرایش روزافزون کشاورزان به تولید ذرت علوفه ای و اهمیت این محصول در جهت حمایت از صنعت دامپروری سبب گردید که پژوهشی با هدف ارزیابی پایداری و کارایی تولید ذرت علوفه ای در شهرستان مرودشت (استان فارس) با استفاده از مدل های فازی، تحلیل فراگیر داده ها (dea)، سامانه اطلاعات جغرافیایی (gis) و تحلیل سلسله مراتبی (ahp) انجام پذیرد. ارزیابی تناسب اراضی با استفاده از gis/ahp از ترکیب خصوصیات خاک و ا...
T2-weighted MRI shows attenuated signals from the basal ganglia, such signal attenuation being more evident at high magnetic field strengths of 1.5 tesla (T). The basal ganglia contain high levels of iron, and it has been suggested that these iron deposits lead to shortening of bulk water T2 protons via a mechanism involving diffusion of water through local magnetic field gradients generated by...
PURPOSE To compare the T staging of potentially resectable esophageal cancer using free-breathing radial VIBE (r-VIBE) and breath-hold Cartesian VIBE (C-VIBE), with pathologic confirmation of the T stage. MATERIALS AND METHODS Fifty patients with endoscopically proven esophageal cancer and indeterminate T1/T2/T3 stage by CT scan were examined on a 3-T scanner. The MRI protocol included C-VIBE...
DVB-T2 is offering a new way for broadcasting value-added services to end users, such as High Definition (HD) TV and 3D TV. Thanks to the advances made in digital signal processing, and specifically in channel coding, DVBT2 brings an increased transfer capacity of 50% and a new flexibility in services’ broadcasting in contrast with the first generation DVB-T standard. As DVB-T2 is still in depl...
Increases in skeletal muscle (1)H-NMR transverse relaxation time (T2) observed by magnetic resonance imaging have been used to map whole muscle activity during exercise. Some studies further suggest that intramuscular variations in T2 after exercise can be used to map activity on a pixel-by-pixel basis by defining an active T2 threshold and counting pixels that exceed the threshold as "active m...
The influence of VAM fungi and bacterial biofertilizer (BBF) with 50% reduction in the recommended dose of (N and P) chemical fertilizers on leaf quality traits of mulberry variety (S-13) and its impact on silkworm (PM ? NB4D2) growth and cocoon characters were studied under semi-arid conditions. Four different treatments were imposed i.e., T1: Control (only 100% NPK); T2: VAM (50% cut in P); ...
آزمایش های لازم برای تعیین اثر مقادیر مختلف آب آبیاری روی پنبه، به مدت دو سال زراعی در ایستگاه تحقیقات پنبه هاشم آباد گرگان اجرا شد. در این پروژه پنج تیمار مقدار آب آبیاری شامل 100%=T1 ، 75%=T2 ، 50%=T3 ، 25%=T4 ، 0%=T5 آب مورد نیاز، در سه تکرار با استفاده از سیستم بارانی کلاسیک و در قالب طرح بلوک های کامل تصادفی مطالعه شدند. تیمارهای آبیاری بر ارتفاع بوته، تعداد قوزه در بوته و عملکرد کل وش در ...
An experiment to observe the growth performance of the larvae produced from female Clarias batrachus treated with 4 dietary levels of vitamin E viz. 0 mg, 50 mg, 100 mg, and 200 mg /kg feed was conducted for 28 days. After rearing for 3 months females were used for induction of breeding to produce larvae. Same dose of pituitary gland (100 mg PG/kg body weight) was used for all treatments. From ...
