Joint inflammation is a key player in the pathogenesis of osteoarthritis (OA). Imperatorin, a plant-derived small molecule has been reported to have anti-inflammatory properties; however, its effect on chondrocytes is not known. Here, we investigated…

Accumulating evidence suggests that inflammation has a key role in the pathogenesis of osteoarthritis (OA). Nitric oxide (NO) has been established as one of the major inflammatory mediators in OA and drives many pathological changes during the…

OBJECTIVE: Mitochondrial dysfunction, oxidative stress and chondrocyte death are important contributors to the development and pathogenesis of osteoarthritis (OA). In this study, we determined the expression and role of Parkin in the clearance of…

Mitochondrial function is impaired in osteoarthritis (OA) but its impact on cartilage catabolism is not fully understood. Here, we investigated the molecular mechanism of mitochondrial dysfunction-induced activation of catabolic response in …

OBJECTIVE: Lysosomes are the major catabolic organelle of the cell and regulate the macromolecular and organelle turnover and programmed cell death. Here, we investigated the lysosome dysfunction in cartilage and its role in chondrocytes apoptosis…

Objective: Cytokine expression is tightly regulated posttranscriptionally, but high levels of interleukin‐6 (IL‐6) in patients with osteoarthritis (OA) indicate that regulatory mechanisms are disrupted in this disorder. The enzyme ZCCHC6 (zinc‐finger…

Osteoarthritis (OA) is the most prevalent joint degenerative disease leading to irreversible structural and functional changes in the joint and is a major cause of disability and reduced life expectancy in ageing population. Despite the high …

Immunofluorescence staining is a widely used and powerful tool for the visualization and colocalization of two or more proteins and/or cellular organelles. For colocalization studies in fixed cells, one target protein/organelle is immunostained and…

OBJECTIVE: To determine the associations between joint metabolism biomarkers and hand radiographic osteoarthritis [(rOA), based on Kellgren Lawrence (KL) grade \textgreater/= 2], symptoms, and function. METHODS: Cross-sectional data were available…

The development of advanced materials that facilitate hyaline cartilage formation and regeneration in aging populations is imperative. Critical to the success of this endeavor is the optimization of ECM production from clinically relevant cells.…

BACKGROUND: Osteoarthritis (OA) is associated with worsening physical function and a high prevalence of comorbid health conditions. In particular, cardiovascular disease (CVD) risk is higher in individuals with OA than the general population.…

The present study examines the reasons cited by 103 patients for their electing to undergo total knee arthroplastic surgery and the relationship between these reasons and their post-operative pain and range of motion. Results suggest that individuals…

Study Design. A descriptive study of the association between sacroiliac joint bridging ( SIB) and age, gender, laterality, and ethnic origin in a normal skeletal population. The effectiveness of radiographs in identifying SIB was also evaluated.…

OBJECTIVES: Recent studies have shown that tRNA-derived RNA fragments (tRFs) are novel regulators of post-transcriptional gene expression. However, the expression profiles and their role in post-transcriptional gene regulation in chondrocytes is…

Objective: The Hartley guinea pig develops articular cartilage degeneration similar to that seen in idiopathic human osteoarthritis (OA). We investigated whether the application of pulsed low-intensity ultrasound (PLIUS) to the Hartley guinea pig…

Objective. In OA, there is enhanced expression of pro-inflammatory cytokines such as IL-1 beta in the affected joint. Delphinidin, an anthocyanidin found in pigmented fruits and vegetables, has been shown to possess anti-inflammatory and antioxidant…

Background: Musculoskeletal complaints represent the second most common reason for visits to a physician, second only to the common cold. The limited capability of medical. treatment for musculoskeletal disease requires modification of communication…

This article contains data related to the article "Wogonin, a plant derived small molecule exerts potent anti-inflammatory and chondroprotective effects through activation of ROS/ERK/Nrf2 signaling pathways in human Osteoarthritis chondrocytes" (Khan…

Study Objective. To determine if changes in blood pressure and changes in class or dosing of antihypertensive drugs were significantly different in patients treated with celecoxib versus rofecoxib, two cyclooxygenase (COX)-2 inhibitors. Design.…

Symptomatic arthritic involvement of the sternoclavicular joint is relatively uncommon and can be a result of distant trauma, infection, and sternocostoclavicular hyperostosis, post-menopausal arthritis, condensing osteitis of the proximal clavicle,…

Objective, To test the hypothesis that magnetic resonance imaging (MRI) results correlate with the biochemical composition of cartilage matrix and can therefore be used to evaluate natural tissue development and the effects of biologic interventions.…

Perspectives are in the eye of the beholder and are expanded with increased scrutiny (e.g., magnification). The term porosity' for macroscopically or radiologically identifiable discontinuity in bone is so variably applied as to be incomprehensible…

Paravertebral osseous masses in reptiles have been attributed to Paget's disease on the basis of histology. Histologically recognized mosaic architecture and cement lines, however, lack specificity. A Varanus dorianus with this condition was…

Odontochelys semitestacea, the oldest known turtle, from the Late Triassic of China, shows a pathology. Sharply defined, focal depressions were noted on the articular surfaces of both humeri, documenting avascular necrosis. Diving habits of Mesozoic…

The purpose of this study was to assess birds as a potential model for osteoarthritis. Compromised by confounding factors, it has not been possible to clearly delineate causation in humans. Nonhuman mammals manifest osteoarthritis in the natural…

The etiology of arthritis in Hyaenidae has been a subject of conjecture. While osteoarthritis has been considered, the observation of an erosive arthritis prompted a systematic survey of museum specimens to define its nature and frequency.…

Spondyloarthropathy was observed in 25 (2.8%) of 895 preserved canid museum specimens and was catalogued by species. The associated skeletal alterations in canids are indistinguishable grossly and physiologically from those in humans with…
