Journal ArticleDOI
Body weight distribution and organ size in newborn swine (sus scrofa domestica) -- a study describing an animal model for asymmetrical intrauterine growth retardation.
Reinhard Bauer,Bernd Walter,Arndt Hoppe,Elke Gaser,Volker Lampe,Eberhard Kauf,Ulrich Zwiener +6 more
TL;DR: Evidence is provided that naturally occurring asymmetrical intrauterine growth restricted newborn piglets can be identified simply by body weight measurement, so that convenient conditions are given for pathogenetically motivated studies on intrauterines compromised newborns.
Journal ArticleDOI
Impact of asymmetric intrauterine growth restriction on organ function in newborn piglets.
TL;DR: Experimental studies in animal models are necessary and helpful to elucidate pathogenetic mechanisms of asymmetric intrauterine growth restriction (aIUGR), which seems to have both beneficial and detrimental effects on the newborn.
Journal ArticleDOI
Mutual information function assesses autonomic information flow of heart rate dynamics at different time scales
TL;DR: The general relevance of the presented AIF approach was confirmed by comparing mutual information, approximate entropy, and sample entropy at their respective time scales.
Journal ArticleDOI
Mutual information and phase dependencies: measures of reduced nonlinear cardiorespiratory interactions after myocardial infarction
TL;DR: It is hypothesized that nonlinear measures of HRV and cardiorespiratory interdependencies are superior to the standard HRV measures in classifying patients after acute myocardial infarction and this result was statistically confirmed by means of logistic regression models of particular variable subsets and their receiver operating characteristics.
Journal ArticleDOI
Validation of the multiple colored microsphere technique for regional blood flow measurements in newborn piglets.
TL;DR: It is concluded that the CMS technique is a valid alternative for RBF measurement in newborn piglets, and that all disadvantages arising form radioactive labeling are thereby avoided.
