Background and purpose:Rheumatoid arthritis (RA) is an autoimmune-inflammatory disease that may lead to joint destruction and disability. The purpose of this study was to evaluate the influence of life style, reproduction, and some external factors on the development of rheumatoid arthritis. Materials and methods:This is a case-control study, comprised of 184 cases and 184 controls. Possible...
It is believed that therapy for rheumatoid arthritis (RA) is the most effective and beneficial within a short time frame around RA diagnosis. This insight has caused a shift from research in patients with established RA to patients at risk of developing RA and recently diagnosed patients. It is important for improvement of RA therapy to understand when and what changes occur in patients develop...
Background: Rheumatoid arthritis (RA) is the most common inflammatory arthritis affecting 0.5 to 1% of the general population worldwide. The cause of RA remains unknown. In active RA, bone turnover markers change in serum and urine before the appearance of erosions in radiography. In this study, we compared RA activity index with bone turnover marker levels in serum of RA patients. Methods:...
most studies within the area of genre analysis, particularly those conducted in iran, have exclusively used text analysis. while such investigations have led to important understandings of generic features of texts, it can be argued that incorporating interview data for triangulation can lead to better understanding of generic features of texts. along this line, this paper reports the results o...
objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...
Abstract Background: Rheumatoid Arthritis, (RA) is a chronic inflammatory autoimmune disease with a progressive course requiring early diagnosis and treatment. The value of anti-cyclic citrullinated peptide antibodies (Anti-CCP) in the diagnosis of RA has been shown in several studies. The present study was designed to determine and compare the diagnostic value of Anti-CCP and rheumatoid fac...
Introduction Maintaining oxygen homeostasis is of vital importance for the survival and development of mammalian cells. Hypoxia (below-normal levels of oxygen in air, blood and tissue) can potentially lead to cellular dysfunction and ultimately cell death and is a feature of many pathological conditions. Understanding how reduced oxygen levels may contribute to or even promote disease is a sign...
