BACKGROUND Carotid angioplasty and stenting can be used in stroke prevention in high-risk patients. As embolic complications can occur during carotid angioplasty and stenting, a device was developed to protect from cerebral embolization. METHODS Between September 1999 and May 2002, carotid angioplasty and stenting was performed in 100 patients (84 men;(More)
This paper proposes a way to improve the position estimates in an indoor location systems (ILS) based on readings from the power levels (RSSI) of an ad hoc ZigBee network. A mobile object, also equipped with a ZigBee device, can be located, positioned, and tracked by the system. The initial estimate of the mobile node position is extracted from IC devices(More)
INTRODUCTION Idiopathic talipes equinovarus is the most common congenital defect characterized by the presence of a congenital dysplasia of all musculoskeletal tissues distal to the knee. For many years, the treatment has been based on extensive surgery after manipulation and cast trial. Owing to poor surgical results, Ponseti developed a new treatment(More)
Recent advances in communications technologies and embedded systems have allowed the development of remote health monitoring systems. There are different approaches depending on the available measurements and the communication system used. In this paper an activity monitoring system is proposed in order to detect falls and/or faints of the user. The feature(More)
A series of long-tail alkyl ethanolamine analogs containing amide-, urea-, and thiourea moieties was synthesized and the behavior of the corresponding monolayers was assessed on the Langmuir-Pockels trough combined with grazing incidence X-ray diffraction experiments and complemented by computer simulations. All compounds form stable monolayers at the soft(More)
Bacterial lipopolysaccharide (LPS) is a known ligand of Toll-like receptor 4 (TLR4) which is expressed in cardiac fibroblasts (CF). Differentiation of CF to cardiac myofibroblasts (CMF) is induced by transforming growth factor-β1 (TGF-β1), increasing alpha-smooth muscle actin (α-SMA) expression. In endothelial cells, an antagonist effect between LPS-induced(More)
