Preliminary Evidence for Correlation Between PASAT Performance and P3a and P3b amplitudes in progressive multiple sclerosis.
(2010)Background. The no-go P3a event-related potential (ERP) is a measure of attentional engagement and the P3b is a measure of context updating. The aim of this study was to compare ERP topographies 1) to Paced Auditory ... -
FASTER: Fully Automated Statistical Thresholding for EEG artifact Rejection
(2010)Electroencephalogram (EEG) data are typically contaminated with artifacts (e.g., by eye movements). The effect of artifacts can be attenuated by deleting data with amplitudes over a certain value, for example. Independent ... -
A high-density ERP study reveals latency, amplitude, and topographical differences in multiple sclerosis patients versus controls.
(2010)Objective. To quantify latency, amplitude and topographical differences in event-related potential (ERP) components between multiple sclerosis (MS) patients and controls and to compare ERP findings with results from ... -
Impaired information processing speed and attention allocation in multiple sclerosis patients versus controls: A high-density EEG study
(2010)Background: The no-go P3a is a variant of the P300 event-related potential (ERP) that indexes speed of information processing and attention allocation. The aim of this study was to compare ERP findings with results from ... -
Altered Brain Activation During a Verbal Working Memory Task in Subjects with Amnestic Mild Cognitive Impairment.
(2010)In subjects with Mild Cognitive Impairment (MCI) memory disorders indicate a high risk for conversion to Alzheimer?s disease (AD). The objective of this study was to delineate the differences in brain activation between ... -
Decreased activation along the dorsal visual pathway after a 3-month treatment with Galantamine in mild Alzheimer's disease
(Wolters Kluwer, 2009)Visual perception has been shown to be altered in Alzheimer?s disease (AD) patients and it is associated with decreased cognitive function. Galantamine is an active cholinergic agent, which has been shown to lead to ... -
Fear-enhanced visual search persists after amygdala lesions
(Elsevier, 2010)Previous research has indicated that the amygdala is a critical neural substrate of the emotional modulation of attention. However, a recent case-study suggests that the amygdala may not be essential for all types of ... -
Electrochemical characterisation of bis(1,10-phenanthroline) gadolinium (III) trichloride formed in situ
(2010)The in situ formation and electrochemical behaviour of a complex between Gadolinium (III) and 1,10-phenanthroline (phen) are discussed. The electron withdrawing ability of phen decreases the redox potential of Gd(III). A ... -
Substrate stiffness and contractile behaviour modulate the functional maturation of osteoblasts on a collagen GAG scaffold
(2010)Anchorage dependent cells respond to mechanical and physical properties of biomaterials. One such cue is a material?s mechanical stiffness. We compared the osteogenic potential of collagen glycosaminoglycan (CG) scaffolds ... -
Temporal discrimination threshold: VBM evidence for an endophenotype in adult onset primary torsion dystonia.
(2009)Familial adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance. Most adult-onset primary torsion dystonia patients are sporadic cases. Disordered sensory processing is found ... -
Acoustic and Temporal Analysis of Speech: A Potential Biomarker for Schizophrenia
(2010)Currently, there are no established objective biomarkers for the diagnosis or monitoring of schizophrenia. It has been previously reported that there are notable qualitative differences in the speech of schizophrenics. The ... -
Propofol allows precise quantitative arterial spin labelling functional magnetic resonance imaging in the rat
(2010)Functional magnetic resonance imaging (fMRI) techniques highlight cerebral vascular responses which are coupled to changes in neural activation. However, two major difficulties arise when employing these techniques in ... -
Spanwise structure of wall pressure on a cylinder in axial flow
(American Institute of Physics, 1999)The spanwise structure of wall pressure fluctuations was measured in an axtisymmetric turbulent boundary layer on a cylinder parallel to the mean flow at a momentum thickness Reynolds number of 2530 and a boundary layer ... -
Bile acid toxicity structure activity relationships: Correlations between cell viability and lipophilicity in a panel of new and known bile acids using an esophageal cell line (HET-1A)
(2010)The molecular mechanisms and interactions underlying bile acid cytotoxicity are important to understand for intestinal and hepatic disease treatment and prevention and the design of bile acid-based therapeutics. Bile acid ... -
A prediction of cell differentiation and proliferation within a collagen-glycosaminoglycan scaffold subjected to mechanical strain and perfusive fluid flow.
(2010)Mesenchymal stem cell (MSC) differentiation can be influenced by biophysical stimuli imparted by the host scaffold. Yet, causal relationships linking scaffold strain magnitudes and inlet fluid velocities to specific cell ... -
Evaluation of a Validation Method for MR Imaging-Based Motion Tracking Using Image Simulation
(2010)Magnetic Resonance (MR) imaging-based motion and deformation tracking techniques combined with finite element (FE) analysis are a powerful method for soft tissue constitutive model parameter identification. However, ... -
Imaging Arterial Fibres Using Diffusion Tensor Imaging Feasibility Study and Preliminary Results
(2010)MR diffusion tensor imaging (DTI) was used to analyze the fibrous structure of aortic tissue. A fresh porcine aorta was imaged at 7T using a spin echo sequence with the following parameters: matrix 128 x 128 pixel; slice ... -
Local and regional mechanical characterisation of a collagen-glycosaminoglycan scaffold using high-resolution finite element analysis.
(2010)Artificial tissue growth requires cells to proliferate and differentiate within the host scaffold. As cell function is governed by mechano-sensitive selection, tissue type is influenced by the microscopic forces exposed ... -
The Mellon Retrospective Cataloguing Project in Trinity College Library Dublin
(2010)This article describes the Mellon Retrospective Cataloguing Project in Trinity College Library Dublin. It gives a description of the Printed Catalogue (holdings up to 1872) and the Accessions Catalogue (1873-1963) and ... -
Women and crisis pregnancy : a report presented to the Department of Health and Children
(Stationery Office, 1998)In June 1995, the Minister for Health, Michael Noonan, commissioned this study on women and crisis pregnancy in Ireland. The study was commissioned to identify the factors which contributed to the incidence of unwanted ...
