In established RA, radiographs reveal joint space narrowing as a result of cartilage loss and characteristic erosions of bone.
A prominent feature of rheumatoid arthritis (RA) is periarticular joint destruction that is associated with poor functional outcome. 1 Synovitis is the primary lesion in RA and is followed by osteitis, osteoclastic mediated joint destruction and the later appearance of characteristic erosions.
The performance characteristics and erosion wear of the pump components are the most critical design and selection parameters.
The film performance can be evaluated by important film properties such as porosity, crystal structure, hardness, surface roughness, electrical characteristics and erosion properties.
Numerical models of two-dimensional flow and sediment transport are used to reveal the structure of the flow field and characteristics of erosion and deposition.
Through systematic numerical simulations, we clearly reveal the detailed changes in multiphase flow characteristics and erosion mechanisms arising from the surface evolution.
Different wave groups were generated over the initially flat beach, and the characteristics of coastal erosion geometry such as erosion lengths, erosion depths, location of maximum erosion point, and total erosion areas were measured.
Their settlements consisting of characteristic sea erosion reinforced houses were located along the Bay of Gdańsk and east of there.
2 4 Hand radiographs demonstrate a characteristic central erosion with collapse of the subchondral bone and a 'gull-wing' or 'saw-tooth' deformity.
16 Psoriatic arthritis (PsA) resembles RA in being an inflammatory disease leading to joint destruction, but differs from RA in several ways including the distribution of affected joints, the presence of skin lesions and enthesopathy, and the absence of rheumatoid factor, characteristic rheumatoid erosions and periarticular osteopoenia on radiographs.
