Cost of Dementia
Background and Aims: The added cost of dementia in the elderly population was shown to be particularly linked to behavioural symptoms. Numerous behavioural symptoms occur over the course of the disease and they affect both patients and caregivers. The present study assesses their influence on resource use. Methods: A cross-sectional analysis of a cohort of 349 dementia patients living in southwestern France was conducted from January to July 2001. The mean Mini-Mental State Examination (MMSE) score at baseline was 16.1 (SD=7.5), with scores ranging from 0 to 30 (respectively the theoretical minimum and maximum) thereby covering all severities of the disease. Behavioural symptoms screened inc...
La méconnaissance des troubles cognitifs dans la maladie d'Alzheimer et autres démences
Afin d'expliquer la méconnaissance des troubles par les malades Alzheimer, deux hypothèses s'opposent dans la littérature : le déni psychologique et l'anosognosie neurologique. Après une revue critique de la littérature rendant compte de résultats contradictoires, nous proposons d'éprouver une hypothèse alternative qui énonce que la méconnaissance des troubles est à la fois du déni et de l'anosognosie. Puis, nous réalisons une étude exploratoire de l'évolution de la perception des troubles cognitifs, chez 52 sujets déments comparés à 52 sujets contrôles de l'étude PAQUID. Nos résultats mettent en évidence des différences peu marquées entre les deux groupes de sujets, contrairement à ce qui est énoncé dans la littérature. Enfin, nous différencions le déni et l'anosognosie dans la maladie d'Alzheimer à partir de l'étude comportementale des individus, et nous éprouvons l'hypothèse de compétences métacognitives publiques et de monitoring plus délétères dans l'anosognosie que dans le déni.

Fluid Interfaces
Fluid interfaces are promising candidates for confining different types of materials, e.g., polymers, surfactants, colloids, and even small molecules, to be used in designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the physicochemical bases underlying the formation of layers at fluid interfaces as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and features of dynamics in the interfacial systems, which are far removed from those conventionally found in traditional materials. This Special Issue is devoted to studies on the fundamental and applied aspects of fluid interfaces, and attempts to provide a comprehensive perspective on the current status of the research field.
Nanostructured Polymer Blends
Over 30% of commercial polymers are blends or alloys or one kind or another. Nanostructured blends offer the scientist or plastics engineer a new range of possibilities with characteristics including thermodynamic stablility; the potential to improve material transparency, creep and solvent resistance; the potential to simultaneously increase tensile strength and ductility; superior rheological properties; and relatively low cost. Nanostructured Polymer Blends opens up immense structural possibilities via chemical and mechanical modifications that generate novel properties and functions and high-performance characteristics at a low cost. The emerging applications of these new materials cover...
Tip Enhancement
This book discusses the recent advances in the area of near-field Raman scattering, mainly focusing on tip-enhanced and surface-enhanced Raman scattering. Some of the key features covered here are the optical structuring and manipulations, single molecule sensitivity, analysis of single-walled carbon nanotubes, and analytic applications in chemistry, biology and material sciences. This book also discusses the plasmonic materials for better enhancement, and optical antennas. Further, near-field microscopy based on second harmonic generation is also discussed. Chapters have been written by some of the leading scientists in this field, who present some of their recent work in this field.·Near-field Raman scattering·Tip-enhanced Raman spectroscopy·Surface-enhanced Raman spectroscopy·Nano-photonics·Nanoanalysis of Physical, chemical and biological materials beyond the diffraction limits·Single molecule detection
