Breeding and production of drought tolerant cultivars for arid and semi-arid area is very important. The present experiment was carried out to evaluate the effects of drought stress on seed yield and yield components of oilseed rape as well as identification of high yielding and drought stress tolerant genotypes. Eighteen new winter oilseed rape lines and commercial cultivars were evaluated und...
An indirect-ELISA for the diagnosis of mixed gastrointestinal (GI) nematode infection comprising Oesophagostomum, Haemonchus and Trichuris species was standardized using crude somatic antigen of Oesophagostomum columbianum (CSAg-Oc) and sera of slaughtered goats with known parasitological status including Oesophagostomum, Haemonchus, and <em...
Background and Aims: Gender determination is an important step in identification. For gender determination, anthropometric evaluation is one of the main forensic evaluations. The aim of this study was the assessment of sphenoid sinus volume in order to determine sexual identity, using multi-slice CT images. Materials and Methods: For volumetric analysis, axial paranasal sinus CT scan with ...
Background & Objective: Mild cognitive impairment (MCI) is a transient state between normal condition and dementia. Available data indicates that coronary artery diseases (CAD) may increase the risk of MCI. Hence, the early detection of MCI can prevent the progression of cognitive decline. Materials & Methods: A sample of 65 subjects with degrees of CAD was enrolled to the study. For cogniti...
background: in myocardial perfusion spect imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. filters greatly affect quality of nuclear medicine images materials and methods: a phantom simulating heart left ventricle was built. about 1mci of 99mtc was injected into the phantom. images were taken from this phantom. some fi...
conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...
This study investigates the importance of selecting an appropriate cut-off frequency in the SWAN model when it is applied to areas with limited fetches. In SWAN, the cut-off frequency is a constant value set by user in the model, and its appropriate selection plays an important role in the accuracy and optimization of the wave model; very high value increases the computational cost and might le...
Background: Finding a reliable diagnostic method for brucellosis is the most challengeable problem. In this study we determined the optimal diagnostic cut-off point for ELISA test.Methods: We gathered 56 confirmed cases of brucellosis. Furthermore blood samples from 126 controls including 73 healthy controls and 53 without brucellosis febrile patients were collected. In all of the cases and con...
سابقه و هدف: فیبروز کبدی نتیجه محتوم بیماری های مزمن کبدی می باشدکه سر انجام به سمت سیروز پیشرفت می کنند. ارزیابی حضور و شدت فیبروز کبدی در بیماران با بیماری مزمن کبدی اهمیت زیادی در تعیین استراتژی درمان، پاسخ به درمان، پروگنوز و ریسک فاکتورهای بالقوه جهت بروز عوارض بیماری دارد. تاکنون بیوپسی کبد بهترین روش ارزیابی فیبروز کبد شناخته شده است ولی از آن جایی که روشی تهاجمی همراه با عوارض زیادی برا...
