Another leading pain researcher, Dr. Roger Chou, an associate professor of medicine at Oregon Health and Science University, noted that the skin creams delivered "very high joint concentrations of the topical Nsaid, higher than with standard oral doses, with very low blood levels" -- less than 5 percent of those found with oral Nsaids.
They also reduce the concentration of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and IL-1β, in joints, [ 41] and systemic and joint concentrations of nitric oxide [ 42] and reactive oxygen species (ROS) [ 43].
The joint OH/acetone concentration images reveal a substantial similarity to premixed flame behavior when the carrier stream is air.
Presence of geometric notches in welded joints causes concentration of strains and stresses, therefore reducing fatigue strength of such joints.
Objective To assess changes in knee joint fluid concentrations of transforming growth factor-β1 (TGF-β1) and proteoglycan (PG) fragments during the early course of post-traumatic osteoarthrosis (OA) after meniscectomy in the rabbit knee, and to ascertain whether the concentrations of these substances shortly after operation could be used as prognostic markers for the OA process.
These results confirm the hypothesis, revealed upon adequate patient phenotyping, that systemic joint tissue concentrations of several biomarkers can be quantitative indicators of specific subspecies of OA and of total body burden of disease.
In inflammatory joints, lower concentration of HA as well as lower molecular weight of HA have been described [ 23].
In adhesively bonded joints, stress concentrations can contribute to the initiation and propagation of cracks in the adhesive.
Especially in diseased joints, local concentrations of inflammatory cytokines present in the cartilage tissue were markedly higher than in synovial fluid.
These differences were not reflected in DAS44 scores, number or distribution of swollen and tender joints, or concentrations of inflammatory markers (Table 1).
