AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Notch1 regulates binary cell fate determination and is critical for angiogenesis and cardiovascular development. However, the pathophysiological role of Notch1 in the postnatal period is not known. We hypothesize that Notch1 signaling in vascular smooth mu ...
Due to the pulsatile nature of blood flow, arteries are constantly exposed to dynamic mechanical forces; the pulsatility continuously stretches the vessel wall and the flow creates a frictional force on the interior surface. These stresses, referred to as ...

The intent of this thesis is to study the function of elastin in cerebral arteries, its contribution into the aging process and its implication into different cerebral diseases and in particular cerebral aneurysms. As of today, little is known on the genes ...

Blood flow in the arterial circulation induces hemodynamic forces that play an important role in various forms of vascular diseases. Temporal variation of the wall shear stress seems to play a significant role in atherogenesis and plaque stability. Flow in ...

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 ...
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 ...
Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and structural arrangement of its main constituents, elastin, collagen, and vascular smooth muscle. Elastin provides for structural integrity and for the compliance of the ...
BACKGROUND: The multifunctional receptor LRP1 controls expression, activity and trafficking of the PDGF receptor-beta in vascular smooth muscle cells (VSMC). LRP1 is also a receptor for TGFbeta1 and is required for TGFbeta mediated inhibition of cell proli ...
Muscular arteries possess the ability to control actively their lumen by altering the tone of the smooth muscle cells of the arterial wall, a property which is vital for a large number of the hemodynamical functions of the body. Arterial contraction is due ...
This thesis aims at better understanding the role played by vascular smooth muscle cells (VSM) in the biomechanics of the arterial wall. Current models assume that under maximal vasodilation VSM carry no load, or the so-called "active stress" is zero. Biom ...
