Leonid Nikolaevich Maslov graduated with honors from the Faculty of Medicine of the Tomsk Medical Institute. In 1991, he defended his dissertation on the topic of "Opiatergic mechanisms of heart protection from arrhythmias during experimental coronary occlusion" for the degree of candidate of medical sciences. In 1996, he defended his dissertation on the topic of "The role of the opioid system in the regulation of arrhythmogenesis and adaptive mechanisms of heart protection under stress" for the degree of doctor of medical sciences. In 2003, he was awarded the academic title of professor. Since 1996, he has been working as the head of the laboratory of experimental cardiology at the Research Institute of Cardiology of the Tomsk National Research Medical Center. The area of ​​scientific interests is the study of the role of opioid and cannabinoid receptors in the regulation of cardiac resistance to ischemia-reperfusion, the study of the molecular mechanisms of the cardioprotective effect of adaptation to hypoxia, the infarct-limiting effect of hypoxic preconditioning, and the molecular mechanisms of cardiac postconditioning.
