Prion Protein is Expressed on Long-term Repopulating Hematopoietic Stem Cells and is Necessary for their Self-renewal

We show that the prion protein (PrP) is expressed on the surface of bone marrow cell populations enriched in long-term repopulating hematopoietic stem cells. Affinity purification of the PrP-positive and PrP-negative fractions from these populations, followed by competitive reconstitution assays, show that all long-term repopulating hematopoietic stem cells express PrP. Hematopoietic stem cells from PrP null bone marrow exhibit impaired self-renewal in serial competitive transplantation experiments, and premature exhaustion when exposed to cell cycle-specific myelotoxic injury. Therefore, PrP is a novel marker for hematopoietic stem cells and regulates their self-renewal.

Comparison of long term cochlear noise injury and age-related cochlear degeneration in mice

This paper studies and compares age related hearing loss and noise-induced hearing loss in mice, and the different cell types that are affected by aging and noise.

Evaluating social skills in long term cochlear implant recipients

A longitudinal study observing cochlear implant recipients' social skills using ratings from their parents and the students themselves over time. The study looked at how adolescents using cochlear implants rate their own social skills compared to an age matched normative group of hearing students, and compared these ratings with social skills ratings obtained from their parents. The study also compared social ratings in adolescence to previous ratings of the same children obtained in elementary school.

Role and potential influence of technologies on the most relevant challenges for long-term care. ENEPRI Research Report No. 113, 26 June 2012

This report considers three case studies (namely diabetes, dementia and obesity) for setting up a framework to assess the systemic influences of technologies in the long-term care milieu, using a problem-driven approach in relation to health care. Such technologies could be an enabling factor or a catalyser of advances taking place in the health and social sectors. They offer opportunities to support and amplify relevant organisational changes in the context of innovative care models, which stem from overall policies and regulations of a national or regional jurisdiction to address the future sustainability of health and social care.

Technological Solutions Potentially Influencing the Future of Long-Term Care. ENEPRI Research Report No. 114, April 2012

This report provides a forecast of the potential direct and indirect influences of various kinds of technologies on the LTC milieu, answering the following question: from a technology-driven perspective: “Consider each technological solution. What could be its future usage in the LTC sector?” Future technological deployments will induce changes in the respective roles of the care recipient and of the formal and informal carers, with an impact on three major concerns: the transformation of the care recipient into a proactive subject, the augmented potentiality for home care and the new functions that informal carers could assume.
