Quantitative morphological analysis of features of remodeling of the synovial membrane vasculature of the temporomandibular joint in hyperglycemia

Medičnì Perspektivi, 2023
The vasulature of the synovial membrane of the temporomandibular joint of 18 laboratory mature Vietnamese mini male pigs divided into 3 groups was morphologically studied. Group 1 – 6 control experimental animals, 2 – 6 pigs with a 30-day’s experimental

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

Advanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

TGFBI Maintains Fibrocartilage Homeostasis by Restraining O‐GlcNAcylation to Inactivate and Destabilize ADAMTS16 in Temporomandibular Joint Osteoarthritis

Advanced Science, EarlyView.
TGFBI deficiency elevates O‐GlcNAcylation, promoting the transcriptional activation of ADAMTS16 and OGT‐mediated post‐translational modification of ADAMTS16 at Ser1170. This leads to its stabilization and accumulation, driving chondrocyte metabolic disorders and senescent phenotypes, ultimately resulting in fibrocartilage dysfunction and TMJOA ...

Temporomandibular joint biomechanical restrictions: The fluid and synovial membrane

, 1999
The authors analyze the functions of the synovial membrane and the chemical-physical properties of synovial fluid. In particular they evaluate the role played by synovial fluid in the complex mechanism of the temporomandibular joint.

Multi‐Tissue Crosstalk Regulating Meniscus Healing Under Inflammation and Physiological Loading

Advanced Science, EarlyView.
Using a novel Meniscus‐on‐a‐chip (MoC) model integrated with a meniscus‐specific bioreactor, this study investigated the roles of multi‐tissue crosstalk that regulates injury, healing, and degeneration of the meniscus injury under inflammation and pathophysiological loading.

Lubrication of synovial membrane. [PDF]

Annals of the Rheumatic Diseases, 1976
(1) An apparatus has been constructed to measure the coefficient of friction of synovial membrane against a glass slider. (2) Provision was made to vary the load on the specimens. (3) The coefficient of friction varied from 0-006 to 0-07. (4) A presentation similar to that used in the Sommerfeld analysis of journal bearings indicated that in these ...
