An Experimental Model of Diet-Induced Metabolic Syndrome in Rabbit: Methodological Considerations, Development, and Assessment Óscar Julián Arias-Mutis1,2,3, Patricia Genovés1,2,3, Conrado J. Calvo1,2,4, Ana Díaz5, Germán Parra2,3, Luis Such-Miquel6, Luis Such2, Antonio Alberola2, Francisco Javier Chorro1,3, Manuel Zarzoso6 1CIBERCV, Instituto de Salud Carlos III, 2Department of Physiology, Universitat de València, 3INCLIVA, 4Department of Electronic Engineering, Universidad Politécnica de Valencia, 5UCIM, Universitat de València, 6Department of Physiotherapy, Universitat de València We describe methods to develop an experimental model of diet-induced metabolic syndrome (MetS) in rabbits using a high-fat, high-sucrose diet. Animals developed central obesity, mild hypertension, pre-diabetes, and dyslipidemia, thus reproducing the main components of human MetS. This chronic model will allow acquisition of knowledge underlying mechanisms of disease progression.

Evaluation of the Complexity of Myocardial Activation During Ventricular Fibrillation. An Experimental Study Revista Espanola De Cardiologia (English Ed.). | Pubmed ID: 24775451 An experimental model is used to analyze the characteristics of ventricular fibrillation in situations of variable complexity, establishing relationships among the data produced by different methods for analyzing the arrhythmia.
QT Interval Heterogeneities Induced Through Local Epicardial Warming/cooling. An Experimental Study Revista Espanola De Cardiologia (English Ed.). | Pubmed ID: 25432709 Abnormal QT interval durations and dispersions have been associated with increased risk of ventricular arrhythmias. The present study examines the possible arrhythmogenic effect of inducing QT interval variations through local epicardial cooling and warming.
Development and Characterization of an Experimental Model of Diet-induced Metabolic Syndrome in Rabbit PloS One. | Pubmed ID: 28542544 Metabolic syndrome (MetS) has become one of the main concerns for public health because of its link to cardiovascular disease. Murine models have been used to study the effect of MetS on the cardiovascular system, but they have limitations for studying cardiac electrophysiology. In contrast, the rabbit cardiac electrophysiology is similar to human, but a detailed characterization of the different components of MetS in this animal is still needed. Our objective was to develop and characterize a diet-induced experimental model of MetS that allows the study of cardiovascular remodeling and arrhythmogenesis. Male NZW rabbits were assigned to control (n = 15) or MetS group (n = 16), fed during 28 weeks with high-fat, high-sucrose diet. We measured weight, morphological characteristics, blood pressure, glycaemia, standard plasma biochemistry and the metabolomic profile at weeks 14 and 28. Liver histological changes were evaluated using hematoxylin-eosin staining. A mixed model ANOVA or unpaired t-test were used for statistical analysis (P
