      Summary: We studied the effects of ethanol on total coronary resistance and on the resistance across the left ventricular wall in the isolated empty beating heart of the dog. The coronaries were perfused with homologous ...
    • Domenech Lira, Raúl; Parra Morales, Víctor (Soc Médica Santiago, 2016)
      The contractile state of the heart is the result of myocardial contractility, the intrinsic mechanism that regulates the force and the shortening of the ventricle and determines the ventricular ejection volume. However, ...
    • Domenech Lira, Raúl; Macho Fisher, Pilar; Barros, Felipe (Oxford University Press, 1990)
      Study objective - The aim was to test the hypothesis of a vascular waterfall in the epicardial veins due to compression by the left ventricular (LV) pressure. If this were so, the epicardial venous pressure should be a ...

      Simple Summary In twin-bearing ewes, undernourishment during pregnancy lowers the birth weight and increases morbidity and mortality of lambs. One of the causes is oxidative stress, which can be prevented by supplementing ...
    • Domenech Lira, Raúl; Macho Fisher, Pilar; Vélez, Diego; Sánchez, Gina; Liu, Xueliang; Dhalla, Naranjan (Lippincott Williams and Wilkins, 1998)
      Background - Myocardial ischemic preconditioning is a well-known phenomenon, however there is scant information in regard to nonischemic preconditioning. Methods and Results - We studied in anesthetized dogs the preconditioning ...
