background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...

background rheumatoid arthritis (ra) is the most common chronic inflammatory disease. the staphylococcal superantigens are considered as the causative agent of ra disease. objectives this study aimed to assess the presence of staphylococcal enterotoxin d in synovial fluid and blood of patients with ra. patients and methods a total of 120 blood and sf samples of patients with ra were studied. ba...

rheumatoid arthritis (ra) is an inflammatory progressive disease which in the absence of appropriate treatment can lead to joint destruction and disability. prognosis of ra may be predicted based on the presence of some clinical and laboratory evidences.new criteria for classification of ra provides opportunity for earlier treatment. initiation of treatment particularly by combination of dmards...

background rheumatoid arthritis (ra) is a chronic inflammatory disease with extra- articular involvement. eyes in particular are one of the most common sites of involvement in rheumatoid arthritis. on the other hand, dry eye syndrome is the most common conflict in terms of management. particular studies suggested dry eye has been associated with greater rheumatoid arthritis severity, but its as...

The EnviSat altimeter, RA-2, is intended to continue an uninterrupted series of measurements of sea-level and ice-sheet elevation started by ERS-1 in 1991. To fully exploit these measurements, an absolute reference in the time series, and a distinction between instrumental artifacts and significant geophysical signals, is necessary. Therefore, the range bias and instrument drift shall be determ...

Reactive oxygen species are known to be potentially dangerous, but are also needed for signal-transduction pathways. Tumor cells have relatively low amounts of superoxide dismutase (SOD), which quenches superoxide anion (O2 •), and as a result of a higher level of aerobic metabolism, higher concentrations of O2 •, compared to normal cells. But this may not be true of all tumor cells. Some tumor...

Background: Due to the obvious differences in the natural course of rheumatoid arthritis (RA) and osteoarthritis (OA),different functional outcomes might be expected after Total Knee Arthroplasty (TKA) in these distinct patients. Althoughseveral studies have reported the objective outcome of TKA in RA and OA patients, few studies have compared postoperativepatient-satisfaction levels.Methods: I...
