Supraventricular Myocardium in the Heart of the B6CBAF1 Mural Strain Reveals Genetically Determined Arrhythmogenic Properties due to Ectopic Automaticity and Triggered Activity

Autor: O. A. Averina, Vladislav S. Kuzmin, V. M. Potekhina

Publikováno v: Moscow University Biological Sciences Bulletin. 74:92-97

A significant amount of studies are aimed at investigating the mechanisms of occurrence and ways to prevent supraventricular arrhythmias, in particular, atrial fibrillation. Its occurrence in most cases is associated with the electrophysiology’s fe

Extracellular Diadenosine Tetraphosphate Suppresses Ectopic Proarrhythmicity in the Myocardial Tissue of the Pulmonary Veins in Adult but not in Neonatal Rats

Autor: Vladislav S. Kuzmin, V. M. Potekhina, Denis V. Abramochkin

Publikováno v: Moscow University Biological Sciences Bulletin. 74:26-32

Diadenosine tetraphosphate (Ap4A) belongs to a group of endogenous purine compounds that have recently been considered as new neurotransmitters or cotransmitters in the autonomic nervous system. It has been shown that Ap4A affects electrophysiology o

Effects of Extracellular Diadenosine Tetraphosphate on Action Potentials in the Atrial and Ventricular Myocardium of the Rat Heart during Early Postnatal Ontogenesis

Autor: K. B. Pustovit, Vladislav S. Kuzmin, N. V. Pakhomov, V. M. Potekhina

Publikováno v: Moscow University Biological Sciences Bulletin. 73:43-49

Diadenosine tetraphosphate (AP4A) belongs to a wide group of naturally derived endogenous purine compounds that have recently been considered as new neurotransmitters in the autonomic nervous system. It has been shown that AP4A induces inhibitory eff

Publikováno v: Purinergic signalling. 15(1)

Extracellular ATP and nicotinamide adenine dinucleotide (β-NAD) demonstrate properties of neurotransmitters and neuromodulators in peripheral and central nervous system. It has been shown previously that ATP and β-NAD affect cardiac functioning in
