Accumulation of PrP(Sc), an abnormal form of cellular prion protein (PrP), in the brain of animals and humans leads to fatal neurodegenerative disorders known as prion diseases. Limited protease digestion of PrP(Sc) produces a truncated form called PrP(27-30) that retains prion infectivity and is the main marker of disease targeted in most diagnostic tests.(More)
OBJECTIVES To identify and characterise different profiles of nurses' utilization of Information and Communication Technology (ICT) and the Internet and to identify factors that can enhance or inhibit the use of these technologies within nursing. METHODS An online survey of the 13,588 members of the Nurses Association of Barcelona who had a registered(More)
OBJECTIVES To identify doctors' utilization of ICT; to develop and characterise a typology of doctors' utilization of ICT and to identify factors that can enhance or inhibit the use of these technologies within medical practice. METHODS An online survey of the 16,531 members of the Physicians Association of Barcelona who had a registered email account in(More)
INTRODUCTION The prion protein (PrP) binds to various molecular partners, but little is known about their potential impact on the pathogenesis of prion diseases RESULTS Here, we show that PrP can interact in vitro with acetylcholinesterase (AChE), a key protein of the cholinergic system in neural and non-neural tissues. This heterologous association(More)
The phenomenon of protein superstructural polymorphism has become the subject of increased research activity. Besides the relevance to explain the existence of multiple prion strains, such activity is partly driven by the recent finding that in many age-related neurodegenerative diseases highly ordered self-associated forms of peptides and proteins might be(More)
Prion diseases are characterized by the accumulation in the central nervous system of an abnormally folded isoform of the prion protein, named PrPSc. Aggregation of PrPSc into oligomers and fibrils is critically involved in the pathogenesis of prion diseases. Oligomers are supposed to be the key neurotoxic agents in prion disease, so modulation of prion(More)
No effective treatment currently exists for prion diseases and therefore the development of experimental non-human primate models of prion neurotoxicity, to better understand the underlying mechanism and to test new treatments relevant to humans, represents an urgent medical need. However, the establishment of such models is challenging due to animal(More)
15 In this paper we study network structures in which the possibilities for cooperation are restricted and the benefits of a group of players depend on how these players are 17 internally connected. One way to represent this type of situations is the so-called reward function, which represents the profits obtainable by the total coalition if links can be(More)
