Physicians' acceptance of telemedicine constitutes a prerequisite for its diffusion on a national scale. Based upon the Theory of Interpersonal Behavior, this study was aimed at assessing the predictors of physicians' intention to use telemedicine in their clinical practice. All of the physicians involved in the RQTE, the extended provincial telemedicine(More)
Maghemite (gamma-Fe2O3) nanocrystals stable at neutral pH and in isotonic aqueous media were synthesized and encapsulated within large unilamellar vesicles of egg phosphatidylcholine (EPC) and distearoyl-SN-glycero-3-phosphoethanolamine-N-[methoxy(poly(ethylene glycol))-2000] (DSPE-PEG(2000), 5 mol %), formed by film hydration coupled with sequential(More)
Maghemite and cobalt ferrite anionic magnetic nanoparticles enter tumor cells and can be used as heat sources when exposed to a high-frequency magnetic field. Comparative studies of the two particles enable to unravel the magnetic heating mechanisms (Néel relaxation vs. Brown relaxation) responsible for the cellular temperature rise, and also to establish a(More)
Iron oxide colloidal nanomagnets generate heat when subjected to an alternating magnetic field. Their heating power, governed by the mechanisms of magnetic energy dissipation for single-domain particles (Brown and Néel relaxations), is highly sensitive to the crystal size, the material, and the solvent properties. This study was designed to distinguish(More)
The Magdalene Islands are an archipelago located in the middle of the Gulf of St Lawrence, more than 1000 km away from supra-regional medical referral centres. We have implemented and evaluated a telemedicine network for the local hospital on the Magdalene Islands. During a 13-month study period, 118 transmissions were made. Orthopaedics and radiology were(More)
BACKGROUND Telehealth, as other information and communication technologies (ICTs) introduced to support the delivery of health care services, is considered as a means to answer many of the imperatives currently challenging health care systems. In Canada, many telehealth projects are taking place, mostly targeting rural, remote or isolated populations. So(More)
Over the last decades, development of home care services is an important component of ongoing health care systems reforms. However, their full integration into hospital or primary care services is still progressing slowly. It appears that telehomecare (THC) could help create networks of services between hospital and primary care providers. Even though their(More)
PURPOSE The purpose of this study is to explore the influence of hospitals' organisational characteristics on telehealth adoption by health-care centres involved in the extended telehealth network of Quebec (French acronym RQTE) DESIGN/METHODOLOGY/APPROACH: The article is based on a review of the literature and a questionnaire, which was administered via(More)
Polyethylene glycol (PEG)ylated and rhodamine-labeled liposomes loaded with maghemite nanocrystals provide a novel nanoscaled hybrid system for magnetic targeting to solid tumors in possible combination with double in vivo imaging by fluorescence microscopy and magnetic resonance imaging (MRI). Human prostate adenocarcinoma tumors implanted in mice were(More)
Intracellular hyperthermia is a process by which malignant cells can be selectively killed by heat generated by nanomediators located inside the cell. Here we show that maghemite anionic nanoparticles are efficiently captured by human prostatic tumor cells (PC3) and concentrate within intracellular vesicles. When submitted to an alternative magnetic field,(More)
