In vivo cyclic loading as a potent stimulatory signal for bone formation inside tissue engineering scaffolds

Dominique Pioletti, Alexandre Terrier, Pierre-Etienne Bourban, Alireza Roshan Ghias

In clinical situations, bone defects are often located at load bearing sites. Tissue engineering scaffolds are future bone substitutes and hence they will be subjected to mechanical stimulation. The goal of this study was to test if cyclic loading can be u ...

Hybrid granular hydrogels: combining composites and microgels for extended ranges of material properties

Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss

Developing hydrogels with optimal properties for specific applications is challenging as most of these properties, such as toughness, stiffness, swelling or deformability, are interrelated. The improvement of one property usually comes at the cost of anoth ...

What static and dynamic properties should slalom skis possess? Judgments by advanced and expert skiers

Jan-Anders Edvin Maansson, Michael Herzog, Olaf Blanke, Pierre-Etienne Bourban, Christian Fischer

Flexural and torsional rigidity are important properties of skis. However, the flexural and torsional rigidity that lead to optimal performance remain to be established. In the present study, four pairs of slalom skis that differed in flexural and torsiona ...

Development of an in situ controllable polymerization tool and process for hydrogel used to replace nucleus pulposus

Dominique Pioletti, Christophe Moser, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

Currently implants or tissue replacements are inserted either as a whole implant or by injecting a liquid which polymerizes to form a solid implant at the appropriate location. This is either highly invasive or not controllable. We developed a tool to perf ...
