BACKGROUND In the previous studies using the commercial ELISA kit, the existence of staphylococcal superantigens has been reported in synovial fluid of patients with rheumatoid arthritis (RA). OBJECTIVES This study aimed to design molecular methods to detect staphylococcal enterotoxin C in synovial fluid of patients with rheumatoid arthritis. MATERIALS AND METHODS In this experimental study...
چکیده سابقه و هدف: توکسین سندرم شوک سمی- 1 و انتروتوکسین ها از جمله فاکتورهای بیماریزایی مهم استافیلوکوکوس اورئوس هستند که همگی سوپرآنتی ژن بوده و در ایجاد سندرم شوک سمی مشارکت می نمایند. در این مطالعه، فراوانی شایع ترین ژن های مولد سندرم شوک سمی (tst، entbو (entcدر ایزوله های بالینی استافیلوکوکوس اورئوس جدا شده از بیماران بستری در بیمارستان های آموزشی شهر قزوین بررسی شد. روش بررسی: در این تحقی...
The multicopper oxidase CueO had previously been demonstrated to exhibit phenoloxidase activity and was implicated in intrinsic copper resistance in Escherichia coli. Catecholates can potentially reduce Cu(II) to the prooxidant Cu(I). In this report we provide evidence that CueO protects E. coli cells by oxidizing enterobactin, the catechol iron siderophore of E. coli, in the presence of copper...
Macrophages are essential for systemic iron recycling, and also control iron availability to pathogens. Iron metabolism in mammalian cells is orchestrated posttranscriptionally by iron-regulatory proteins (IRP)-1 and -2. Here, we generated mice with selective and combined ablation of both IRPs in macrophages to investigate the role of IRPs in controlling iron availability. These animals are hyp...
a r t i c l e i n f o Federal and state governments spend well over a billion dollars a year on programs that encourage employment development in disadvantaged labor markets through the use of subsidies and tax credits. In this paper we use an estimation approach that is valid under relatively weak assumptions to measure the impact of State Enterprise Zones (ENTZs), Federal Empowerment Zones (E...
conclusions based on the findings of this study, s. aureus enterotoxin c (sec) has been detected in synovial fluid of patients with rheumatoid arthritis by pcr and elisa methods. these valuable findings may describe the exact etiology of the ra and as well as change the methods of its diagnosis and treatment. this is the first research, which has shown the staphylococcal entc gene in synovial f...
