Tensorial Electrokinetics in Articular Cartilage [PDF]

open access: yesBiophysical Journal, 2006
Electrokinetic phenomena contribute to biomechanical functions of articular cartilage and underlie promising methods for early detection of osteoarthritic lesions. Although some transport properties, such as hydraulic permeability, are known to become anisotropic with compression, the direction-dependence of cartilage electrokinetic properties remains ...

Segmentation of articular cartilage and early osteoarthritis based on the fuzzy soft thresholding approach driven by modified evolutionary ABC optimization and local statistical aggregation [PDF]

open access: yes, 2019
Articular cartilage assessment, with the aim of the cartilage loss identification, is a crucial task for the clinical practice of orthopedics. Conventional software (SW) instruments allow for just a visualization of the knee structure, without post ...

Pyrophosphate‐Containing Calcium Phosphates Negatively Impact Heterotopic Bone Quality

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of calcium pyrophosphate (Ca‐PP) in heterotopic bone formation and material degradation is investigated using calcium phosphate (CaP) compositions with varying Ca‐PP content. Results show that Ca‐PP does not impede heterotopic bone formation, minimally affects CaP degradation at non‐osseous sites, and increases phagocytosis.

Nutrition and degeneration of articular cartilage [PDF]

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, 2012
To determine the importance of synovial fluid (SF) or subchondral bone marrow (BM) as nutrition sources in cartilage degeneration.Ninety-five-month-old male rabbits were randomly divided into 5 groups according to sources of nutrition: SFBM-both; BM-only; SF-only; None-SFBM; and Free plug (unrestricted).

The degeneration and destruction of femoral articular cartilage shows a greater degree of deterioration than that of the tibial and patellar articular cartilage in early stage knee osteoarthritis: a cross-sectional study [PDF]

open access: yes, 2014
SummaryObjectiveThe aim of the present study was to examine whether the degenerative and morphological changes of articular cartilage in early stage knee osteoarthritis (OA) occurred equally for both femoral- and tibial- or patellar- articular cartilage ...

Immunosuppressive Cytokine‐Tethered Hydrogel for Treating Rheumatoid Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
An injectable hydrogel is developed by chemically tethering IL‐4, an immunosuppressive cytokine, to a hyaluronic acid‐based backbone. The hydrogel reduces joint friction and exerts immunomodulatory effects. In a rheumatoid arthritis (RA) mouse model, it reduced inflammation, preserved cartilage, and promoted anti‐inflammatory immune responses.

Primary cilia disassembly down-regulates mechanosensitive hedgehog signalling: a feedback mechanism controlling ADAMTS-5 expression in chondrocytes [PDF]

open access: yes, 2014
SummaryObjectiveHedgehog signalling is mediated by the primary cilium and promotes cartilage degeneration in osteoarthritis. Primary cilia are influenced by pathological stimuli and cilia length and prevalence are increased in osteoarthritic cartilage ...

Magnetically targeted delivery through cartilage

open access: yesAIP Advances, 2018
In this study, we have invented a method of delivering drugs deep into articular cartilage with shaped dynamic magnetic fields acting on small metallic magnetic nanoparticles with polyethylene glycol coating and average diameter of 30 nm.

A Bio‐Inspired Perspective on Materials Sustainability

open access: yesAdvanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...
