rheumatoid arthritis (ra) is a chronic autoimmune disease, which can lead to joint destruction and disability. pannus formation due to chronic synovitis is the hallmark of ra. oxidative stress as a consequence of immune cell activation and disease-modifying anti-rheumatic drugs can prevent inflammation and tissue destruction. silymarin, an antioxidant extract from silybum marianum, has been tra...

in this study, the natural convection heat transfer of variable properties al2o3-eg-water nanofluid in a differentially heated rectangular cavity has been investigated numerically. the governing equations, for a newtonian fluid, have been solved numerically with a finite volume approach. the influences of the pertinent parameters such as ra in the range of 103-107 and volume fraction of nanopar...

Background: Over 2 million deaths from the COVID-19 disease have been reported in world. Since no antiviral treatment is available, vaccination most important option to fight SARS-CoV-2 infection. Patients living with rheumatoid arthritis (RA) affecting immune system or under immunosuppressive agent will be considered as a high risk population and start shortly. But many patients could decline ...

background and objectives: mycoplasma arthritidis mitogen (mam) superantigen has been shown to induce chronic arthritis, which resembles human rheumatoid arthritis (ra) in a rodent model. however, its role as a causative agent in human ra is not well understood yet. the aim of this study was to investigate the presence of mam superantigen gene in the synovial fluid (sf) of ra patients. material...
