Biomechanical investigation of a new implant for cervical spine fusion

Dominique Pioletti, Arne Christian Vogel, Michael Davatz

The project consists of: - mechanical tests of the prototype of the new implant and comparison to existing anterior fixation systems in a bone model material; - a literature review in order to classify the test results; - the development of a finite elemen ...

Synthesis of poly(methacrylic acid) brushes via surface-initiated atom transfer radical polymerization of sodium methacrylate and their use as substrates for the mineralization of calcium carbonate

Harm-Anton Klok, Stefano Tugulu, Raphaël Barbey

This manuscript describes the synthesis of poly(methacrylic acid) (PMAA) brushes via surface-initiated atom transfer radical polymerization (SI-ATRP) of sodium methacrylate (NaMA) and their use as substrates for the mineralization of calcium carbonate. A C ...

Hierarchical interconnections in the nano-composite material bone: Fibrillar cross-links resist fracture on several length scales

Georg Fantner

Bone is a complex and very important multi-constituent bio-composite. In this work, we focus on the arrangement of bone constituents from the nanoscopic to the microscopic scale, and investigate the influence of their arrangements on the fracture mechanism ...

Bone tissue engineering using fetal cell therapy

Dominique Pioletti

Different cell sources for bone tissue engineering are reviewed. In particular, adult cell source strategies have been based on the implantation of unfractionated fresh bone marrow; purified, culture expanded mesenchymal stem cells, differentiated osteobla ...

A new technique for imaging mineralized fibrils on bovine trabecular bone fracture surfaces by atomic force microscopy

Georg Fantner

High resolution atomic force microscopy (AFM) images of bovine trabecular bone fracture surfaces reveal individual fibrils coated with extrafibrillar mineral particles. The mineral particles are distinctly different in different regions. In some regions th ...

Novel techniques for high-resolution functional imaging of teabecular bone

Georg Fantner, Randoald Müller

In current biological and biomedical research, quantitative endpoints have become an important factor of success. Classically, such endpoints were investigated with 2D imaging, which is usually destructive and the 3D character of tissue gets lost. 3D imagi ...

Optimizing the solar photo-fenton process in the treatment of contaminated water. Determination of intrinsic kinetic constants for scale-up

César Pulgarin

The elimination of aromatic compounds present in surface water by photo-Fenton with sunlight as the source of radiation was studied. The concentrations of Fe3+ and H2O2 are key factors for this process. A solar simulator and a prototype parabolic collector ...

Bleaching and photobleaching of Orange II within seconds by the oxone/Co2+ reagent in Fenton-like processes

Albert Renken, Juan Kiwi, Javier Fernandez

Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was obsd. with oxone in solns. with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2 ...

Fetal bone cells for tissue engineering

Dominique Pioletti, Corinne Scaletta, Pierre-François Leyvraz

We envision the use of human fetal bone cells for engineered regeneration of adult skeletal tissue. A description of their cellular function is then necessary. To our knowledge, there is no description of human primary fetal bone cells treated with differe ...

A strain energy function for arteries accounting for wall composition and structure

Nikolaos Stergiopoulos, Martin Zulliger

Identification of a Strain Energy Function (SEF) is used when describing the complex mechanical properties of soft biological tissues such as the arterial wall. Classic SEFs, such as the one proposed by Chuong and Fung (J. Biomech. Eng. 105(3) (1983) 268), ...
