An Overview of Serum Albumin Interactions with Biomedical Alloys

Stefano Mischler, Anna Neus Igual Muñoz, Oksana Klok

Understanding the interactions between biomedical alloys and body fluids is of importance for the successful and safe performance of implanted devices. Albumin, as the first protein that comes in contact with an implant surface, can determine the biocompat ...

Quantitative approaches to unravel bone marrow adipocyte site-specificity and its implication in hematopoiesis

Josefine Catharina Pedersen Tratwal

Over the last decade, bone marrow (BM) adipose tissue (BMAT) has emerged as a distinct adipose depot with unique metabolic properties and effects both in homeostasis and in the progression of disease. We provide a first comprehensive review of existing an ...

Experimental investigation of mesoscale variability of clear spruce mechanical properties in the radial direction

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin, Steffen Franke

The aim of this work is the investigation of mesoscale/local variability in mechanical properties of clear timber in the radial direction. Clear Norway spruce wood, Picea abies, was used for cutting specimens of different lengths with a small cross-section ...

Influence of low curing temperatures on the tensile response of low clinker Strain Hardening UHPFRC under full restraint

Emmanuel Denarié, Mohamed Abdul Hafiz

The tensile response of strain hardening UHPFRC under full restraint, subjected to curing temperatures of 20 °C, 10 °C, 5 °C, was investigated for two types of mixes with silica fume; Mix I with pure type I cement and Mix II with 50% replacement of cement ...

Rapid evaluation of bioactive Ti-based surfaces using an in vitro titration method

Paul Bowen, Jacques Lemaître, Weitian Zhao

The prediction of implant behavior in vivo by the use of easy-to-perform in vitro methods is of great interest in biomaterials research. Simulated body fluids (SBFs) have been proposed and widely used to evaluate the bone-bonding ability of implant materia ...

Bioengineering human bone marrow models to elucidate the triggers of the stem cell niche

Queralt Vallmajó Martín

The bone marrow (BM) microenvironment, or niche, significantly affects behaviors of its resident stem cell populations. Disruptions in the BM niche contribute to a number of severe clinical pathologies. Discovery of novel therapeutic strategies for BM-rela ...

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 ...

Adsorption of HPDX and CaHPOx (x=1, ...,4) molecules on anatase TiO2 (001) surfaces

Alfonso Baldereschi, Michel Posternak

perform DFT calculations within the COSMO framework to study the adsorption properties of the CaHPOx (x = 1,...,4) phosphate family, and of the related HPOx acids, on a paradigmatic anatase (001) surface. Of particular interest is CaHPO4, a precursor of hy ...

A Sustainable Approach to Produce Stiff, Super-Tough, and Heat-Resistant Poly(lactic acid)-Based Green Materials

Nicolas Candau, Oguzhan Oguz, Mehmet Kerem Citak, Fatma Nalan Cetin

Circumventing inherent embrittlement, poor heat resistance, and melt elasticity of poly(lactic acid) (PLA) without compromising its remarkable stiffness and strength has become a particular challenge in polymer science due to increasing demand for green ma ...
