Studies of 1-hexyl-3-methyl-imidazolium ethylsulfate ([HMIM] EtSO4) using an extended surface forces apparatus show, for the first time, an ordered structure within the nanoconfined ionic liquid (IL) between mica surfaces that extends up to ∼60 nm from the surface. Our measurements show the growth of this ordered IL-film upon successive nanoconfinements-the structural changes being irreversible...

In this work we are studying whether calcium phosphate deposition (CPD) during vascular calcification is a passive or a cell-mediated mechanism. Passive CPD was studied in fixed vascular smooth muscle cells (VSMC), which calcify faster than live cells in the presence of 1.8 mM Ca²(+) and 2 mM P(i). CPD seems to be a cell-independent process that depends on the concentration of calcium, phosphat...

Purpose Describes a network of training centres (TCN-LIS) to support continuing professional development (CPD) of library and information specialists, in countries of Central and Eastern Europe and Central Asia, funded by the Open Society Institute (OSI). Draws some general lessons for CPD in the library / information sector. Design/methodology/approach Reviews the development and activities of...

PURPOSE To determine the effects of defocus-induced blur adaptation on human contrast sensitivity (CS) function. METHODS Defocused (+2 D) CS was measured for spatial frequencies between 0.5 and 12 cycles per degree (cpd) before and after adaptation to +2 D blur in six subjects with normal vision. During the 30-minute adaptation period with +2 D lens, subjects were exposed to a succession of s...

The introduction of Continuing Professional Development (CPD) to encourage individual life-long learning as a way of maintaining professional competency in pharmacy has faced resistance. To investigate ways to address this barrier we included CPD with portfolio in a university Pharmaceutics course. Underpinning knowledge for the course was delivered using a flipped classroom approach and studen...

Exposure of DNA to ultraviolet light produces harmful crosslinks between adjacent pyrimidine bases, to form cyclobutane pyrimidine dimers (CPDs) and pyrimidine(6-4)pyrimidone photoproducts. The CPD is frequently formed, and its repair mechanisms have been exclusively studied by using a CPD formed at a TT site. On the other hand, biochemical analyses using CPDs formed within cytosine-containing ...

PURPOSE To compare visual function after bilateral implantation of multifocal Lentis Mplus LS-312 (Group A) or Acrysof Restor SN6AD1 (Group B) intraocular lenses (IOLs). SETTING Ophthalmology Unit, Centro Hospitalar e Universitário de Coimbra, and Visual Neuroscience Laboratory, IBILI, Faculty of Medicine, University of Coimbra, Coimbra, Portugal. DESIGN Comparative case series. METHODS P...
