A tissue kallikrein in the synovial fluid of patients with rheumatoid arthritis [PDF]

, 1989
Tissue kallikrein is an enzyme that forms the vasoactive peptide kallidin from an endogenous substrate L-kininogen. Tissue kallikrein has been identified in joint fluids and in inflammatory infiltrates within synovial membranes.

Early rheumatoid arthritis is characterized by a distinct and transient synovial fluid cytokine profile of T cell and stromal cell origin [PDF]

, 2005
Pathological processes involved in the initiation of rheumatoid synovitis remain unclear. We undertook the present study to identify immune and stromal processes that are present soon after the clinical onset of rheumatoid arthritis ( RA) by assessing a ...

Synovial fluid presepsin as a novel biomarker for the rapid differential diagnosis of native joint septic arthritis from crystal arthritis

International Journal of Infectious Diseases, 2021
Objective: To investigate whether presepsin can be used as a novel biomarker to differentiate between native joint septic arthritis (NJSA) and crystal arthritis (CA). Methods: This study included 75 patients diagnosed with either NJSA (n = 21) or CA (n =

Characterization of the porcine synovial fluid proteome and a comparison to the plasma proteome

Data in Brief, 2015
Synovial fluid is present in all joint cavities, and protects the articular cartilage surfaces in large by lubricating the joint, thus reducing friction. Several studies have described changes in the protein composition of synovial fluid in patients with

Hyaluronic acid synthesis, degradation, and crosslinking in equine osteoarthritis: TNF-α-TSG-6-mediated HC-HA formation

Arthritis Research & Therapy, 2021
Background TNF-α-stimulated gene 6 (TSG-6) protein, a TNF-α-responsive hyaladherin, possesses enzymatic activity that can catalyze covalent crosslinks of the polysaccharide hyaluronic acid (HA) to another protein to form heavy chain-hyaluronic acid (HC ...

Investigation on the Influence of Synovial Fluid and Vitreous Humour on Avulsion Wounds Healing in Rabbits [PDF]

Archives of Razi Institute, 2021
In the present study, we investigated the efficacy of vitreous humour and synovial fluid on avulsion wound healing in a rabbit’s model. The vitreous humour is a fluid that resembles gel consisting of approximately 98–99% water, little hyaluronic acid ...
