NANBIOSIS scientists in Aragón, explain on TV their research againts coronavirus

The special program on the coronavirus pandemic  by “En Ruta con la Ciencia” of Aragón Televisión, analyzes different aspects of the disease with special attention to the work of Aragonese scientists. Among them, two  research groups that coordinate NANBIOSIS units 9 and 27. Starting at minute 44’45 ‘of the program, Doctor Jesús Lázaro, researcher of the BSICoS group of I3A-UZ and CIBER-BBN, led by Pablo Laguna, which coordinates NANBIOSIS U27 High Performance Computing Unit, explains his research. For almost 3 years, Jesús Lázaro had been working on a European project to develop a respiratory and heart rate monitoring system for[...]

NANBIOSIS researchers featured in the 15th Edition of Spanish Researchers Ranking

The 15th edition of the Webometrics Ranking of World Universities has been published, ranking researchers in Spain as well as Spaniards doing research abroad. A total of 11 Directors of NANBIOSIS units appear on the most recent list, featured on the top 2000. The list is ordered by the h-index, a metric that calculates research impact based on a correlation of papers published and number of citations, and then by number of citations. The result is a list of whose’s publications have had more impact online. NANBIOSIS researchers featured are Fernando Albericio (#207), scientific director of U3 Synthesis of Peptides[...]

Automatic Detection of Slow Conducting Channels during Substrate Ablation of Scar-Related Ventricular Arrhythmias

Researchers of BSICoS Group form CIBER-BBN and I3A-Unizar, coordinating NANBIOSIS Unit 27 tooghether with researchers of Physense group of UPF and Hospital Clinic have carried out the research which results have been just published by Journal of Interventional Cardiology. The researchers propose automatic analysis of EGM signals using the “Slow Conducting Channel Mapping Algorithm” that improves the accuracy of bipolar voltage measurements within the scar area, achieving a more detailed tissue characterization and being an operator-independent tool for accurate identification of SCCs. This last feature encourages the use of the algorithm together with EAM navigation systems as a reproducible approac[...]

Neurocardiac Oscillation in Repolarization and Cardiac Arrhythmias

David Sampedro and Esther Pueyo, from NANBIOSIS Unit 27 High Performance Computing (CIBER-BBN, I3A-UZ) have conducted a research about Neurocardiac Oscillation in Repolarization and Cardiac Arrhythmias. Recent studies in humans and dogs have shown that ventricular repolarization exhibits a low-frequency (LF) oscillatory pattern following enhanced sympathetic activity, which has been related to arrhythmic risk. The appearance of LF oscillations in ventricular repolarization is, however, not immediate, but it may take up to some minutes. This study seeks to characterize the time course of the action potential (AP) duration (APD) oscillatory behavior in response to sympathetic provocations, unveil its underlying mechanisms[...]
