Local and systemic inflammatory lipid profiling in a rat model of osteoarthritis with metabolic dysregulation. [PDF]
PLoS ONE, 2018 Bioactive oxidised lipids (oxylipins) are important signalling mediators, capable of modulating the inflammatory state of the joint and anticipated to be of importance in joint homeostasis and status of osteoarthritis.

Designing Fluid-Exuding Cartilage for Biomimetic Robots Mimicking Human Joint Lubrication Function [PDF]
The human joint is an open-type joint composed of bones, cartilage, ligaments, synovial fluid, and joint capsule, having advantages of flexibility and impact resistance. However, replicating this structure in robots introduces friction challenges due to the absence of bearings.

Recent progress in cartilage lubrication [PDF]
arXiv, 2023 Healthy articular cartilage, covering the ends of bones in major joints such as hips and knees, presents the most efficiently-lubricated surface known in nature, with friction coefficients as low as 0.001 up to physiologically high pressures. Such low friction is indeed essential for its well being.

Osteoarthritis and Cartilage Open, 2022 Objective: Exercise is known to induce beneficial effects in synovial joints. However, the mechanisms underlying these are unclear. Synovial joints experience repeated mechanical loading during exercise.

Existence of global weak solutions for unsteady motions of incompressible chemically reacting generalized Newtonian fluids [PDF]
arXiv, 2018 We study a system of nonlinear partial differential equations describing the unsteady motions of incompressible chemically reacting non-Newtonian fluids. The system under consideration consists of the generalized Navier-Stokes equations with a power-law type stress-strain relation, where the power-law index depends on the concentration of a chemical ...

A method for delineation of bone surfaces in photoacoustic computed tomography of the finger [PDF]
, 2015 Photoacoustic imaging of interphalangeal peripheral joints is of interest in the context of using the synovial membrane as a surrogate marker of rheumatoid arthritis. Previous work has shown that ultrasound produced by absorption of light at the epidermis reflects on the bone surfaces within the finger.

Thanatochemistry: Study of synovial fluid potassium
Alexandria Journal of Medicine, 2014 Death interval estimation is one of the major attributes obtained from thanatochemistry. Body fluids like vitreous humour have been consistently used to estimate death interval from regression equations, but these may be useless when dealing with eye ...

International Journal of Microbiology, 2014 We quantify the false-negative diagnostic rate of septic arthritis using Gram-stain microscopy of synovial fluid and compare this to values reported in the peer-reviewed literature.

FrictionChanges in the components of synovial fluid in the human body have an important influence on the tribological behavior of artificial joints. Based on the concentration of components in the synovial fluid after arthroplasty, “hard−soft” joint pair ...

Finite element approximation of an incompressible chemically reacting non-Newtonian fluid [PDF]
arXiv, 2017 We consider a system of nonlinear partial differential equations modelling the steady motion of an incompressible non-Newtonian fluid, which is chemically reacting. The governing system consists of a steady convection-diffusion equation for the concentration and the generalized steady Navier-Stokes equations, where the viscosity coefficient is a power ...
