The Greek NDI needs cross-cultural validation and there is no methodologically sound information selleck compound for the Swedish NDI. For all other languages we advise to translate the original version of the NDI.”
“Background: The objective of this study was the quantification of myocardial motion from 3D tissue phase mapped (TPM) CMR. Recent work on myocardial motion quantification by TPM has been focussed on multi-slice 2D acquisitions thus excluding motion information from large regions of the left ventricle. Volumetric motion assessment appears an important next step towards the understanding of the volumetric myocardial motion and hence
may further improve diagnosis and treatments in patients with
myocardial motion abnormalities.
Methods: Volumetric motion quantification of the complete left ventricle was performed in 12 healthy volunteers and two patients applying a black-blood 3D TPM sequence. The resulting motion field was analysed regarding motion pattern differences between apical and basal locations as well as for asynchronous motion pattern between different myocardial www.selleckchem.com/products/bms-345541.html segments in one or more slices. Motion quantification included velocity, torsion, rotation angle and strain derived parameters.
Results: All investigated motion quantification parameters could be calculated from the 3D-TPM data. Parameters quantifying hypokinetic or asynchronous motion demonstrated differences between motion impaired and healthy myocardium.
Conclusions: 3D-TPM enables the gapless volumetric quantification of motion abnormalities of the left ventricle, which can be applied in future application as additional information to provide a more detailed analysis
of the left ventricular function.”
“Wireless Sensor Networks (WSNs) are very promising tools in the advanced automation of chemical-analysis processes. Basically, they are formed by many small devices – called sensor nodes or motes – that can obtain information from the surrounding area using appropriate transducers, and communicate it by suitable wireless-transmission systems.
In this article, Selleck Duvelisib we study both the application of WSN technology to analytical chemistry and the new research fields for analytical chemistry opened up by the success of WSN applications. A basic “”chemical-applied”" description of WSNs is followed by the reasons for their implementation and their use in chemical-analysis processes, and comments on the most relevant contributions developed so far. Finally, this article also deals with future trends in this field.
Key research challenges to be addressed to deliver remote, wireless, chemosensing systems include the development of low-cost, low-consumption sensors. (C) 2012 Elsevier Ltd. All rights reserved.
