Helium atoms are known to have a significant impact on materials used in fission and fusion reactors. In particular, the presence of helium atoms can change the mechanical properties and degrade the lifetime of reactors. In order to develop the helium-resi ...

Photodynamic therapy (PDT) with Visudyne acts by direct cellular phototoxicity and/or by an indirect vascular-mediated effect. Here, we demonstrate that the vessel integrity interruption by PDT can promote the extravasation of a macromolecular agent in nor ...

Novel use of X-ray micro computed tomography to image rat sciatic nerve and integration into scaffold

Stéphanie Lacour

This paper describes how specimens of nervous tissue can be prepared for successful imaging in X-ray Micro Computed Tomography (μCT), and how this method can be used to study the integration of nervous tissue into a polymeric scaffold. The sample preparati ...

Arterial remodeling using a constituent-based approach

Alkiviadis Tsamis

This thesis is intended to contribute to the field of biomechanics of growth and remodeling of arteries. The work focuses particularly on growth and remodeling caused by sustained hypertension, increased blood flow, and ageing. A structure-based constituti ...

Color centers in NaCl by hybrid functionals

Wei Chen

We present in this work the electronic structure and transition energies (both thermodynamic and optical) of Cl vacancies in NaCl by hybrid density functionals. The underestimated transition energies by the semilocal functional inherited from the band-gap ...

Extended Focus Optical Coherence Microscopy

Martin Villiger

Optical coherence tomography (OCT) is an interferometric imaging technique that can provide depth resolved cross-sectional views of biological tissue. OCT employs light with low temporal and yet high spatial coherence. The sample is illuminated point by po ...

Intercellular calcium dynamics in smooth muscle cells

Dominique Seppey

Muscular arteries are able to actively modify their diameter by modulating the tone of the smooth muscle cells located within the arterial wall. A small variation of lumen diameter has a large influence on blood flow as well as on arterial pressure. The ca ...

Modélisation mécanique de fils pour la simulation chirurgicale

Lindo Robert Duratti

Minimally Invasive Surgery (MIS) represents one of the major progresses in surgery in the last decade. In general, it is based on the application of small body-cuts through which instruments are inserted into the patient's body allowing the surgeon to carr ...

Spatial-temporal regulation of bone morphogenetic protein (BMP) and Wnt activity is essential for normal cardiovascular development, and altered activity of these growth factors causes maldevelopment of the cardiac outflow tract and great arteries. In the ...

Shear stress and cyclic circumferential stretch, but not pressure, alter connexin43 expression in endothelial cells

Nikolaos Stergiopoulos, Paolo Silacci

Hemodynamic forces play a critical role in atherogenesis, as evidenced by the focal pattern of development of atherosclerotic lesions. Whereas disturbed flow in the branches and curved regions of large arteries is proatherogenic, laminar flow in the straig ...
