A novel electrophysiologic effect of melatonin on ischemia/reperfusion- induced arrhythmias in isolated rat hearts
(Wiley Blackwell Publishing, Inc, 2009-03)
Reperfusion after a short period of cardiac ischemia triggers ventricular arrhythmias attributable to ionic imbalance and oxidative stress. Melatonin offers some degree of protection, but its effects on the cardiac action ...
Electrophysiological effects of tamoxifen: mechanism of protection against reperfusion arrhythmias in isolated rat hearts
(Lippincott Williams, 2013-08)
Reperfusion arrhythmias are currently attributed to ionic imbalance and oxidative stress. Tamoxifen is a potent antioxidant that also modulates some ionic transport pathways. In this work, we tried to correlate the ...
Grape pomace reduced reperfusion arrhythmias in rats with a high-fat-fructose diet
(Royal Society of Chemistry, 2017-10)
Metabolic syndrome (MetS) is a risk factor for sudden cardiac death in humans, but animal models are needed for the study of this association. Grape pomace (GP), obtained from the winemaking process, contains phenolic ...

Ablation of phospholamban rescues reperfusion arrhythmias but exacerbates myocardium infarction in hearts with Ca2+ /calmodulin kinase II constitutive phosphorylation of ryanodine receptors
(Oxford University Press, 2019-03)
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 ...
Reperfusion arrhythmias increase after superior cervical ganglionectomy due to conduction disorders and changes in repolarization
(Molecular Diversity Preservation International, 2020-03)
Pharmacological concentrations of melatonin reduce reperfusion arrhythmias, but less is known about the antiarrhythmic protection of the physiological circadian rhythm of melatonin. Bilateral surgical removal of the superior ...
Ischemic Postconditioning Reduces Reperfusion arrhythmias by Adenosine Receptors and Protein Kinase C Activation but Is Independent of KATP Channels or Connexin 43
(Molecular Diversity Preservation International, 2019-11)
Ischemic postconditioning (IPoC) reduces reperfusion arrhythmias but the antiarrhythmic mechanisms remain unknown. The aim of this study was to analyze IPoC electrophysiological effects and the role played by adenosine A1, ...
Macrophage-dependent IL-1β production induces cardiac arrhythmias in diabetic mice
(Nature Publishing Group, 2016-11)
Diabetes mellitus (DM) encompasses a multitude of secondary disorders, including heart disease. One of the most frequent and potentially life threatening disorders of DM-induced heart disease is ventricular tachycardia ...
