Structural and Tribological Analysis of Healthy and Pathological Synovial Fluids

چکیده
Recent studies have shown the existence of two types of discontinuous lipid structures in the synovial fluid lubricant film: (i) the lipid multilayers which form the synovial fluidcartilage interface [Purbach, Clin.Orthop.Relat.Res.2002], and (ii) lipid vesicles present within lubricant films [Watanabe, Med.Electron.Microsc.2000]. The size of these lipid vesicles, compared to the thickness of the lubricant film estimated by hydrodynamics lubrication models [Jin and Dowson, ProcI.MEJ.J.Eng.Tribol.2005], is the subject of a controversy. The aim of this study was to analyze the role of discontinuous lipid structures in the lubrication mechanism in healthy and pathological joints.

Analyzing the synovial fluid is one of the common methods to diagnose the articular problems to detect the stage and express the prognosis. Such gross, cytological, and biochemical analysis of synovial fluids can aid in the diagnosis of various joint diseases. Objectives: Normal values for synovial fluid in the camels have been described previously; however, there are no reports regarding conce...
متن کاملComparison of the immune response to Epstein-Barr virus and cytomegalovirus in sera and synovial fluids of patients with rheumatoid arthritis.
The immune response against two herpesviruses has been determined in sera and matched synovial fluids of patients with rheumatoid arthritis (RA) and compared with that of a healthy control population. The increased level of antibody to Epstein-Barr virus (EBV) induced antigens in patients with RA resembles the antibody pattern observed against cytomegalovirus (CMV) induced antigens, which sugge...
متن کاملSynovial fluid matrix metalloproteinase-2 and -9 activities in dogs suffering from joint disorders
The activity of matrix metalloproteinase (MMP)-2 and MMP-9 in synovial fluids (SF) sampled from dogs with joint disorders was investigated by gelatin zymography and densitometry. Pro-MMP-2 showed similar activity levels in dogs with idiopathic polyarthritis (IPA; n=17) or canine rheumatoid arthritis (cRA; n=4), and healthy controls (n=10). However, dogs with cranial cruciate ligament rupture (C...
متن کاملA Study of the Tribological Properties of Sputter-deposited MoSX/Cr Coatings
In this investigation, MoSx/Cr coatings were deposited by direct-current magnetron sputter onto Ck45 (AISI 1045) plain carbon steel substrates. The MoSx/Cr ratio in the coatings was controlled by sputtering the composite targets. The chemical characterization was performed using EDX (energy dispersive X-ray analysis); the structural characterization was accomplished by X-ray diffraction (XRD) s...
