    Filogonio R, Wang T, Taylor E, Abe A, Leite C. Vagal tone regulates cardiac shunts during activity and at low temperatures in the South American rattlesnake, Crotalus durissus. J Comp Physiol B. 2016;186:1059-1066 pubmed
    ..We conclude that vagal control of pulmonary conductance is an active mechanism regulating cardiac shunts in C. durissus. ..

    ..Our data also suggests that NO exerts a tonic dampening of myocardial oxygen consumption which may be particularly important during aestivation. ..
  4. Filogonio R, Alcantara Costa Leite C, Wang T. Vascular distensibilities have minor effects on intracardiac shunt patterns in reptiles. Zoology (Jena). 2017;122:46-51 pubmed publisher
    ..We speculate that the lack of correlation in these phylogenetically distant species may indicate that this is a common trend within non-crocodilian reptiles. ..

    ..We hope these suggestions may help future clarification of the relative importance of passive arterial mechanical properties compared to autonomic regulation in determining intracardiac shunts in both amphibians and reptiles. ..
