سابقه و هدف: کندروما و کندروسارکوما با درجه تمایز بالا، نمای هیستوپاتولوژیک بسیار مشابهی دارند. علیرغم این شباهت، ماهیت بیولوژیک این دو تومور متفاوت است. اشتباه در تشخیص دقیق پاتولوژیک این دو ضایعه سبب می‌شود طرح درمان بیماران با اشکال مواجه شود و در صورت تشخیص اشتباه، ناخواسته بیماران تحت جراحی وسیع قرار گیرند. در این زمینه، نقش نشانگرهای ایمونوهیستوشیمیایی در تشخیص افتراقی تومورهای غضروفی مور...
Background and Objective: According to the complications of dementia, its screening is important in elderly stage. Dementia screening tests need to have acceptable sensitivity and specificity. This study aimed at determining the cut-off point of the Persian version of Clinical Dementia Rating (P-CDR) and testing its diagnostic accuracy in the early detection of dementia among the elderly....
Objectives : The aim of this study was to assess the validity and reliability of the Persian version of the Conners’ Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Screening Scale (screening form-self reporting). Method: The Persian version of the scale was produced through translation to Persian, back-translation and confirming the accuracy of translation. The face and content validit...
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...
We present a novel algorithm for collision detection between two discretely oriented polytopes (k-DOPs). It is an application of the well known Separating Axes Test to k-DOPs and is implemented in fixed-point arithmetic. Hence, it lends itself very well to hardware implementation. In this report we focus on the derivation of the algorithm and an error-bound on the rounding-error produced by the...
cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...
Background: Introduction: Searching for an ideal marker for diagnosing neonatal infection is still an important concern in every country. There are many biomarkers reported for neonatal sepsis. Haptoglobin is an acute phase reactants which rise in response to infection and injuries. In this report we discussed the efficacy of serum haptoglobin level in different cut off levels in early onset ne...
