Système de régulation de pression agissant localement sur la peau et le tissu sous-cutané

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

The invention relates to a system for adjusting pressure locally acting on the skin. Said system includes a set of adjacent modules distributed so as to form a layer. Each module includes a cushion capable of changing shape and comprising a cavity, a valve ...

The biofilm granulation mechanisms depend on the predominant populations involved

Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter

The novel aerobic granular sludge technology is attractive for intensified biological nutrient removal from wastewater. This process is based on self-granulated flocs forming fast-settling mobile biofilms with a gel-like consistence, called “granules”. Mec ...

Patient-specific mean pressure drop in the systemic arterial tree, a comparison between 1-D and 3-D models

Nikolaos Stergiopoulos, Philippe Reymond, François Lazeyras

One-dimensional models of the systemic arterial tree are useful tools for studying wave propagation phenomena, however, their formulation for frictional losses is approximate and often based on solutions for developed flow in straight non-tapered arterial ...

Engineering of Signaling Microenvironments with Fibronectin Domains to Enhance Tissue Regeneration

Mikaël Martino

Conducting tissue healing and regeneration through biomaterials and morphogens is still an unrealized goal. Understand the multiple roles of the extracellular matrix (ECM) is indeed essential for the design of successful regenerative medicine strategies. D ...

Extracellular matrix in angiogenesis: dynamic structures with translational potential

Jeffrey Alan Hubbell

The vascular network is an integral component of most organs. Beyond assuring an adequate supply of oxygen and nutrients for normal tissue function, vascular structures provide also a critical interface in the balance of tissue homoeostasis and immune func ...

Two-Phase Pressure Drops in Adiabatic Horizontal Circular Smooth U-Bends and Contiguous Straight Pipes (RP-1444)

John Richard Thome, Ricardo Lima

Curved channels in the form of bends are encountered in many industrial two-phase flow applications, such as U-bends in air-conditioning and refrigeration evaporators and condensers. For engineering design purposes, the evaluation of the pressure loss in t ...

Nitroxyl exacerbates ischemic cerebral injury and oxidative neurotoxicity

Friedhelm Christoph Hummel, Sonia Donzelli

Nitroxyl (HNO) donor compounds function as potent vasorelaxants, improve myocardial contractility and reduce ischemia-reperfusion injury in the cardiovascular system. With respect to the nervous system, HNO donors have been shown to attenuate NMDA receptor ...

Individualization of transfer function in estimation of central aortic pressure from the peripheral pulse is not required in patients at rest

Nikolaos Stergiopoulos, Nico Westerhof

Central aortic pressure gives better insight into ventriculo-arterial coupling and better prognosis of cardiovascular complications than peripheral pressures. Therefore transfer functions (TF), reconstructing aortic pressure from peripheral pressures, are ...

Wound-healing defect of CD18(-/-) mice due to a decrease in TGF-beta1 and myofibroblast differentiation

Boris Hinz

We studied the mechanisms underlying the severely impaired wound healing associated with human leukocyte-adhesion deficiency syndrome-1 (LAD1) using a murine disease model. In CD18(-/-) mice, healing of full-thickness wounds was severely delayed during gra ...

Impaired skin wound healing in peroxisome proliferator-activated receptor (PPAR)alpha and PPARbeta mutant mice

Denis Duboule, Jozsef Zakany, Walter Wahli

We show here that the alpha, beta, and gamma isotypes of peroxisome proliferator-activated receptor (PPAR) are expressed in the mouse epidermis during fetal development and that they disappear progressively from the interfollicular epithelium after birth. ...
