In the heart, Ca2+ influx through L-type Ca2+ channels triggers Ca2+ release from the sarcoplasmic reticulum. In most mammals, this influx occurs during the ventricular action potential (AP) plateau phase 2. However, in murine models, the influx thro

The present work shows that SR Ca2+ load and RYR2 Ca2+ sensitivity are major determinants of Ca2+ release restitution (CRR) after each heartbeat. Mathematical modeling led us to speculate that the velocity of SR Ca2+ refilling might regulate CRR inde

Key points Mice with Ca(2+) -calmodulin-dependent protein kinase (CaMKII) constitutive pseudo-phosphorylation of the ryanodine receptor RyR2 at Ser2814 (S2814D(+/+) mice) exhibit a higher open probability of RyR2, higher sarcoplasmic reticulum (SR) C

Phase 1 repolarization rate defines Ca

Publikováno v: The Journal of General Physiology
Intact heart physiology assessed by local-field optical techniques helps decipher cardiac function at the organ level. Here, we found that the phase 1 repolarization rate of the mouse ventricular action potential defines contractility by regulating t

Aims Abnormal Ca2+ release from the sarcoplasmic reticulum (SR), associated with Ca2+-calmodulin kinase II (CaMKII)-dependent phosphorylation of RyR2 at Ser2814, has consistently been linked to arrhythmogenesis and ischaemia/reperfusion (I/R)-induced

Experimental assessment of a myocyte-based multiscale model of cardiac contractile dysfunction
Autor: Sandra Wray, Edmundo I. Cabrera-Fischer, Juan Ignacio Felice, Pierre Dauby, Elena C. Lascano, Sara Kosta, Jorge A. Negroni
Publikováno v: Journal of theoretical biology. 456
Cardiac contractile dysfunction (CD) is a multifactorial syndrome caused by different acute or progressive diseases which hamper assessing the role of the underlying mechanisms characterizing a defined pathological condition. Mathematical modeling ca

Nitration of nitrobenzene in Fenton’s processes
Autor: Juan M. Triszcz, Daniela Nichela, Luciano Carlos, Juan Ignacio Felice, Fernando Sebastián García Einschlag
Publikováno v: Chemosphere. 80:340-345
Previous studies of nitrobenzene (NB) degradation by Fenton and photo-Fenton technologies have demonstrated the formation and accumulation of 1,3-dinitrobenzene (1,3-DNB) as a highly toxic reaction intermediate. In the present study, we analyze the c
