Simultaneous Quantitation of Cationic and Non-ionic Contrast Agents in Articular Cartilage Using Synchrotron MicroCT Imaging

Goran Lovric

Early diagnosis of acute cartilage injuries enables monitoring of disease progression and improved treatment option planning to prevent post-traumatic osteoarthritis. In contrast-enhanced computed tomography (CECT), the changes in cationic agent diffusion ...

Relationships between cartilage thickness and subchondral bone mineral density in non-osteoarthritic and severely osteoarthritic knees: In vivo concomitant 3D analysis using CT arthrography

Julien Favre, Brigitte Jolles-Haeberli

Objective: To test whether subchondral bone mineral density (sBMD) and cartilage thickness (CTh) of femoral condyles are correlated in knees without and with severe medial femorotibial osteoarthritis (OA), using a subregional analysis with computerized tom ...

Efficacy of pulsed electromagnetic fields and electromagnetic fields tuned to the ion cyclotron resonance frequency of Ca2+ on chondrogenic differentiation

Philippe Renaud, Harald Van Lintel

Previous studies provide strong evidence for the therapeutic effect of electromagnetic fields (EMFs) on different tissues including cartilage. Diverse exposure parameters applied in scientific reports and the unknown interacting mechanism of EMF with biolo ...

The role of mechanical hysteresis source in mechanical and mechanobiological performances of load-bearing biomaterials

Naser Nasrollahzadeh Mamaghani

Tissue engineering is a promising approach for articular cartilage regeneration as no satisfactory treatment is actually available for cartilage, partly due to the very limited self-healing capability of this tissue. To successfully induce a cartilaginous ...

Control of Dissipation Sources: A Central Aspect for Enhancing the Mechanical and Mechanobiological Performances of Hydrogels

Dominique Pioletti, Peyman Karami, Naser Nasrollahzadeh Mamaghani

Development of mechanically durable and biologically inductive hydrogels is a major challenge for load-bearing applications such as engineered cartilage. Dissipative capacity of articular cartilage is central to its functional behavior when submitted to lo ...

Depth-dependent mechanical properties of human articular cartilage obtained by indentation measurements

Pierre-Etienne Bourban, Lee Ann Laurent-Applegate, Matteo Gregorio Modesto Marascio, Robin Martin, Jens Antons

Emerging 3D printing technology permits innovative approaches to manufacture cartilage scaffolds associated with layer-by-layer mechanical property adaptation. However, information about gradients of mechanical properties in human articular cartilage is li ...

3D Printing and Supercritical Foaming of Hierarchical Cellular Materials

Matteo Gregorio Modesto Marascio

Hierarchical porous structures have been gathering interest in different fields owing to their unique properties associated with their multi-scale features. The observation of natural materials brought new insights into the functionality of cellular materi ...

Decellularised tissues obtained by a CO2-philic detergent and supercritical CO2

Dominique Pioletti, Pierre-Etienne Bourban, Nathalie Hirt-Burri, Matteo Gregorio Modesto Marascio, Jens Antons, Pierre-Arnaud Aeberhard

Tissue decellularisation has gained much attention in regenerative medicine as an alternative to synthetic materials. In decellularised tissues, biological cues can be maintained and provide cellular environments still unmet by synthetic materials. Supercr ...

Modeling knee osteoarthritis pathophysiology using an integrated joint system (IJS): a systematic review of relationships among cartilage thickness, gait mechanics, and subchondral bone mineral density

Julien Favre, Brigitte Jolles-Haeberli

Objective: To introduce an integrated joint system (IJS) model of joint health and osteoarthritis (OA) pathophysiology through a systematic review of the cross-sectional relationships among three knee properties (cartilage thickness, gait mechanics, and su ...

Composite Double-Network Hydrogels To Improve Adhesion on Biological Surfaces

Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi, Peyman Karami, Céline Samira Wyss, Martin Broome

Despite the development of hydrogels with high mechanical properties, insufficient adhesion between these materials and biological surfaces significantly limits their use in the biomedical field. By controlling toughening processes, we designed a composite ...
