Background In rheumatoid arthritis (RA) many patients harbor autoantibodies against post translationally modified proteins (anti-modified protein antibodies (AMPA)): anti-citrullinated (ACPA), anti-carbamylated (anti-CarP) and anti-acetylated (AAPA). All three AMPA have been described to be associated with an increase in radiographic joint damage ACPA also a lower chance of obtaining sustained ...
A 73-year-old man with a history of myasthenia gravis (MG) was diagnosed with rheumatoid arthritis (RA) based on a history of polyarthritis and positivity for anti-citrullinated protein antibodies (ACPA). He presented with a high level of serum vascular endothelial growth factor (VEGF) and RS3PE syndrome-like pitting edema in the extremities, which improved following treatment with low-dose pre...
BACKGROUND Follicular structures resembling germinal centres (GCs) that are characterized by follicular dendritic cell (FDC) networks have long been recognized in chronically inflamed tissues in autoimmune diseases, including the synovium of rheumatoid arthritis (RA). However, it is debated whether these ectopic structures promote autoimmunity and chronic inflammation driving the production of ...
Holographic transmission gratings with a spatial frequency of 2658 lines/mm and reflection gratings with a spatial frequency of 4553 lines/mm were stored in a polyvinyl alcohol (PVA)/acrylamide (AA) based photopolymer. This material can reach diffraction efficiencies close to 100% for spatial frequencies about 1000 lines/mm. However, for higher spatial frequencies, the diffraction efficiency de...
BACKGROUND This article provides an overview of modern serological diagnostic testing for rheumatoid arthritis (RA) involving the detection of antibodies against citrullinated peptides/proteins (ACPA). Recommendations are also given for differential diagnosis and sequential testing in rheumatoid arthritis, with a view towards improving early diagnosis, so that irreparable joint damage can be av...
در این پژوهش آثار پروپیل گالات که از فعالیت اکسیداز انتهایی پلاستید دخیل در تنفس کلروپلاستی جلوگیری می¬کند، بر کارایی فتوسیستم ii در جلبک سبز تک سلولی dunaliella salina با استفاده از اندازه¬گیری کینتیک فلوئورسنس کلروفیل a مطالعه شده است. تیمار کشتهای جلبکی با غلظتهای 1/0، 5/0، 1، 2 و 4 میلی¬مولار پروپیل گالات نشان داد که کارایی فتوسیستم ii در حضور غلظتهای تا 1 میلی¬مولار افزایش یافته...
Anti-citrullinated peptide antibodies (ACPA) have a very high specificity for rheumatoid arthritis, much more than that of the rheumatoid factor. In addition, ACPA can be found in sera in the pre-clinical phase, are associated with more severe joint destruction and with higher disease activity. In recent years, keeping pace with new knowledge and with progress made in the antigenic composition ...
OBJECTIVE Two interferon regulatory factor 5 (IRF5) gene variants were examined for association with rheumatoid arthritis (RA). METHODS A total of 2300 patients with RA and 1836 controls were recruited from 2 independent RA studies in Sweden. One insertion-deletion polymorphism (CGGGG indel) and one single-nucleotide polymorphism (rs10488631) in the IRF5 gene were genotyped and analyzed withi...
BACKGROUND Anti-carbamylated protein (anti-CarP) antibodies have recently been reported to occur in around 45% of rheumatoid arthritis (RA) patients and to have prognostic and diagnostic properties. At present, the breadth and molecular make-up of the anti-CarP antibody response is ill defined. To understand the anti-CarP antibody immune response and potential immune effector mechanisms it can ...
