Cardiac electrical defects in progeroid mice and Hutchinson-Gilford progeria syndrome patients with nuclear lamina alterations
(2016-11-15)
Article
Open AccessHutchinson–Gilford progeria syndrome (HGPS) is a rare genetic disease caused by defective prelamin A processing, leading to nuclear lamina alterations, severe cardiovascular pathology, and premature death. Prelamin A ... -
Data-based fault detection in chemical processes: Managing records with operator intervention and uncertain labels
(2016-06-23)
Article
Open AccessDeveloping data-driven fault detection systems for chemical plants requires managing uncertain data labels and dynamic attributes due to operator-process interactions. Mislabeled data is a known problem in computer science ... -
Detection, properties, and frequency of local calcium release from the sarcoplasmic reticulum in teleost cardiomyocytes
(2011-08-29)
Article
Open AccessCalcium release from the sarcoplasmic reticulum (SR) plays a central role in the regulation of cardiac contraction and rhythm in mammals and humans but its role is controversial in teleosts. Since the zebrafish is an ... -
Distribution and function of cardiac ryanodine receptor clusters in live ventricular myocytes
(2015-08-14)
Article
Open AccessThe cardiac Ca2+ release channel (ryanodine receptor, RyR2) plays an essential role in excitation-contraction coupling in cardiac muscle cells. Effective and stable excitation-contraction coupling critically depends not ... -
Enhanced plant fault diagnosis based on the characterization of transient stages
(Pergamon Press, 2011-12-05)
Article
Restricted access - publisher's policyThis paper introduces a data-based fault diagnosis system that includes an enhanced characterization of faults during transient stages. First, data under abnormal operating conditions (AOC) is projected onto a reference ... -
How to merge observational and physiological data? A case study of motor skills patterns and heart rate in exercise programs for adult women
(2017-10-01)
Article
Open AccessThe present study analyzes individual and group heart rate responses in exercising adult women. The specific aim was to compare responses during routine workout sessions within a community exercise program with responses ... -
Human-robot cooperative movement training: learning a novel sensory motor transformation during walking with robotic assistance-as-needed
(BioMed Central Ltd., 2007-03-31)
Article
Open AccessBackground A prevailing paradigm of physical rehabilitation following neurologic injury is to "assist-as-needed" in completing desired movements. Several research groups are attempting to automate this principle with ... -
Identification of intracellular calcium dynamics in stimulated cardiomyocytes
(IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Conference report
Open AccessWe have developed an automatic method for the analysis and identification of dynamical regimes in intracellular calcium patterns from confocal calcium images. The method allows the identification of different dynamical ... -
Identifying basketball plays from sensor data; towards a low-cost automatic extraction of advanced statistics
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policyAdvanced statistics have proved to be a crucial tool for basketball coaches in order to improve training skills. Indeed, the performance of the team can be further optimized by studying the behaviour of players under certain ... -
Low density lipoproteins promote unstable calcium handling accompanied by reduced SERCA2 and connexin-40 expression in cardiomyocytes
(2013-03-13)
Article
Open AccessThe damaging effects of high plasma levels of cholesterol in the cardiovascular system are widely known, but little attention has been paid to direct effects on cardiomyocyte function. We therefore aimed at testing the ... -
Motor adaptation as a greedy optimization of error and effort
(The American Physiological Society, 2007-03-31)
Article
Restricted access - publisher's policythought of as a process in which the nervous system learns to anticipate the environmental forces to eliminate kinematic error. Here we show that motor adaptation can more generally be modeled as a process in which the ... -
Multilevel analysis of calcium dynamics in stimulated cultures of cardiomyocytes
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Restricted access - publisher's policyWe present an automatic method to characterize calcium activity in a culture of cardiac cells from a sequence of microscopy fluorescence images. The approach quantifies both the response of each individual cell in the ... -

Phospholamban knockout breaks arrhythmogenic Ca2+ waves and suppresses catecholaminergic polymorphic ventricular tachycardia in mice
(2013-07-15)
Article
Restricted access - publisher's policyRationale: Phospholamban (PLN) is an inhibitor of cardiac sarco(endo)plasmic reticulum Ca2+ ATPase. PLN knockout (PLN-KO) enhances sarcoplasmic reticulum Ca2+ load and Ca2+ leak. Conversely, PLN-KO accelerates Ca2+ ... -
