The mechanical properties of aortic wall, both healthy and pathological, are needed in order to develop and improve diagnostic and interventional criteria, and for the development of mechanical models to assess arterial integrity. This study focuses on the mechanical behaviour and rupture conditions of the human ascending aorta and its relationship with age(More)
Viscoelastic models can be used to better understand arterial wall mechanics in physiological and pathological conditions. The arterial wall reveals very slow time-dependent decays in uniaxial stress-relaxation experiments, coherent with weak power-law functions. Quasi-linear viscoelastic (QLV) theory was successfully applied to modeling such responses, but(More)
INTRODUCTION AND OBJECTIVES The thermomechanical behavior of human arteries is still not well characterized despite its importance for understanding arterial physiology, and for evaluating and improving surgical procedures. The aim of this study was to provide, for the first time, experimental data illustrating how the mechanical responses of two types of(More)
OBJECTIVES Our main objective was to biologically improve rotator cuff healing in an elderly rat model using mesenchymal stem cells (MSCs) in combination with a collagen membrane and compared against other current techniques. METHODS A chronic rotator cuff tear injury model was developed by unilaterally detaching the supraspinatus (SP) tendons of(More)
The defence industry is moving rapidly towards new types of agreement such as availability contracts based on Industrial Product-Service System (IPS2) business models. Obsolescence has become one of the main problems that will impact on a system during its life cycle. Most of the research carried out has been focused on electronic components, neglecting the(More)
