First paleoproteome study of fossil fish otoliths and the pristine preservation of the biomineral crystal host

Anders Meibom, Jaroslaw Hubert Stolarski, Jinming Guo

Otoliths are calcium carbonate components of the stato-acoustical organ responsible for hearing and maintenance of the body balance in teleost fish. During their formation, control over, e.g., morphology and carbonate polymorph is influenced by complex ins ...

Microtensile failure mechanisms in lamellar bone: Influence of fibrillar orientation, specimen size and hydration

Johann Michler, Daniele Casari, Tatiana Kochetkova

A mechanistic understanding of bone fracture is indispensable for developing improved fracture risk assessment in clinics. Since bone is a hierarchically structured material, gaining such knowledge requires analysis at multiple length scales. Here, the ten ...

Structural description of surfaces and interfaces in biominerals by DNP SENS

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

Biological mineralized tissues are hybrid materials with complex hierarchical architecture composed of biominerals often embedded in an organic matrix. The atomic-scale comprehension of surfaces and organo-mineral interfaces of these biominerals is of para ...

In vitro and in vivo investigation of bisphosphonate-loaded hydroxyapatite particles for peri-implant bone augmentation

Dominique Pioletti, Ulrike Kettenberger

Locally applied bisphosphonates, such as Zoledronate, have been shown in several studies to inhibit peri-implant bone resorption and recently to enhance peri-implant bone formation. Studies have also demonstrated positive effects of hydroxyapatite particle ...

Compounds for functionalizing biomaterials

Sandrine Gerber, Françoise Borcard

The present invention provides compounds suitable for functionalizing biomaterials, in particular prosthetics and implant materials, functionalized biomaterials, and methods for synthesizing the compound. The compounds contain an anchoring group, a group f ...

Improving the osteogenic potential of BMP-2 with hyaluronic acid hydrogel modified with integrin-specific fibronectin fragment

Jeffrey Alan Hubbell, Mikaël Martino

While human bone morphogenetic protein-2 (rhBMP-2) is a promising growth factor for bone regeneration, its clinical efficacy has recently shown to be below expectation. In order to improve the clinical translation of rhBMP-2, there exists strong motivation ...

Osteoconductive surfaces generated from peptide functionalized poly(2-hydroxyethyl methacrylate-co-2-(methacryloyloxy)ethyl phosphate) brushes

Harm-Anton Klok, Dusko Paripovic

Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD ...

68Ga-NODAGA-RGDyK for αvβ3 integrin PET imaging. Preclinical investigation and dosimetry

Carole Poitry-Yamate, Christian Rüegg, Serge Baechler, David Viertl

To visualize neovasculature and/or tumour integrin αvβ3 we selected the binding moiety Arg-Gly-Asp-D-Tyr-Lys (RGDyK) coupled to NODAGA for labeling with 68Ga. ...

Engineering of Signaling Microenvironments with Fibronectin Domains to Enhance Tissue Regeneration

Mikaël Martino

Conducting tissue healing and regeneration through biomaterials and morphogens is still an unrealized goal. Understand the multiple roles of the extracellular matrix (ECM) is indeed essential for the design of successful regenerative medicine strategies. D ...

Experimental characterization of the distribution of collagen fiber recruitment

Nikolaos Stergiopoulos, Sylvain Roy, Christophe Boss

The passive biomechanical behavior of blood vessels is generally modeled by a parallel arrangement of elastin and collagen, with collagen recruitment depending on vessel strain. We experimentally determined the collagen recruitment distribution using confo ...
