BACKGROUND The aim of the present study was to evaluate the accuracy of two approaches using magnetic resonance imaging (MRI) or combined ultrasonography (US) and anti-cyclic citrullinated peptide antibody (ACPA) for diagnosis and classification of individuals with established rheumatoid arthritis (RA). METHODS In 53 individuals from a population-based, cross-sectional study, historic fulfilm...
conclusions bilateral anterior shoulder dislocation is rare. it could be undiagnosed, especially when there is no clear history of major trauma. by awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome. introduction shoulder dislocation is the most common presentation of joint dislocation in emergency department (ed). bilateral shoulder d...
امروزه عرضه میوهها به صورت قطعات بریده شده از ارزش اقتصادی بالایی برخوردار میباشد، ولی میوه برشخورده معمولا در مرحله پس از برداشت و زمان نگهداری دچار قهوهای شدن آنزیمی شده و با حمله عوامل بیماریزا مواجه میشوند. در این تحقیق برای افزایش عمر قفسهای قطعات برشخورده خرمالو از تیمارهای اسید آسکوربیک (یک درصد به مدت دو دقیقه)، اسید اگزالیک (5/0 درصد به مدت دو دقیقه)، 1-MCP (یک میکرولیتر در لی...
BACKGROUND The development of osteoarthritis (OA) in the hand results in increased joint stiffness, which in turn affects the grip strength. The goal of the present study is to theoretically analyze the muscle forces in a thumb in response to the increased joint stiffness. METHODS The thumb was modeled as a linkage system consisting of a trapezium, a metacarpal bone, a proximal and a distal p...
AIM Accurate diagnosis and early treatment in rheumatoid arthritis (RA) can lead to a good outcome and a correct management of the disease. We aimed toinvestigate the prognostic value of anti-RA33 antibodies, by evaluating the relationship with ultrasonographic (US) findings in patients with early RA. MATERIAL AND METHODS We performed a prospective study which included 29 patients, diagnosed ...
Background During the transition to rheumatoid arthritis (RA) many patients pass through a phase characterised by the presence of symptoms without clinically apparent synovitis. These symptoms are not well-characterised. This taskforce aimed to define the clinical characteristics of patients with arthralgia who are considered at risk for RA by experts based on their clinical experience. Methods...
OBJECTIVE To evaluate a low field dedicated extremity MRI unit for detection of bone erosions, synovitis, and bone marrow oedema in wrist and metacarpophalangeal (MCP) joints, with a high field MRI unit as the standard reference. METHODS In 37 patients with RA and 28 healthy controls MRI of the wrist and 2nd-5th MCP joints was performed on a low field MRI unit (0.2 T Esaote Artoscan) and a hi...
Background Bone erosion in rheumatoid arthritis (RA) is most commonly detected the wrist, metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joints. High-resolution peripheral quantitative computed tomography (HR-pQCT) has successfully been used to quantify bone erosions wrist MCP A recent study highlights that HR-pQCT of only two joints equal accuracy detect erosive disease RA patients co...
OBJECTIVES To compare subjective estimation with computerized quantification of synovial perfusion in active RA, develop new quantitative scores, establish quantitative limit values for the respective grades in order to achieve even distribution and compare the new scores with the established semi-quantitative score. METHODS Patients fulfilling the 2010 RA classification criteria in whom US s...
در این رساله صفحه میکروکانال تخت یا micro channel plate (mcp) را به عنوان عامل اصلی تقویت الکترون در آشکارسازهای هسته ای و نیز سامانه های دید در شب با یک رویکرد کاربردی مورد بررسی دقیق قرار داده ایم. علاوه بر این نحوه ساخت این قطعه و نحوه بکارگیری آن در این سامانه ها بیان شده است و نیز یک کد کامپیوتری بر مبنای روش مونت کارلو با توجه به رفتار آماری گسیل الکترون های ثانویه در این قطعه توسعه داد ش...
