Efeitos da abolição da bradicardia reflexa nas respostas cardiorrespiratórias de tambaqui, Colossoma macropomum (Cuvier, 1818), em hipóxia severa: vagotomia versus inibição farmacológica
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2013-06-14)
Hypoxic bradycardia is a reflex response to hypoxia observed in most fish species studied so far. This reflex is initiated by the stimulation of O2 chemoreceptors and induced by an increase in the inhibitory vagal tonus. ...
Branchial O2 chemoreceptors in Nile tilapia Oreochromis niloticus: Control of cardiorespiratory function in response to hypoxia
(2013-09-01)
This study examined the distribution and orientation of gill O2 chemoreceptors in Oreochromis niloticus and their role in cardiorespiratory responses to graded hypoxia. Intact fish, and a group with the first gill arch ...
A influência da hipóxia severa na sensibilidade barorreflexa de tilápia-do-Nilo (Oreochromis niloticus)
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2019-03-15)
The importance of the circulatory system in homeostasis of different animals is unquestionable. Given that one of the basic factors that determine blood flow is blood pressure, the short- and long-term regulation of this ...

Respostas cardiorrespiratórias do teleósteo de respiração aérea, Clarias gariepinus, exposto à hipóxia gradual
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2010-06-25)
Air-breathing fish are classified as obligatory (when breathing obligatory atmospheric air independently of the water O2 tension) or facultative air-breather (using an air breathing organ ABO -, when theirs gills are not ...
The role of branchial and orobranchial O-2 chemoreceptors in the control of aquatic surface respiration in the neotropical fish tambaqui (Colossoma macropomum): progressive responses to prolonged hypoxia
(Company of Biologists Ltd, 2006-05-01)
The present study examined the role of branchial and orobranchial O-2 chemoreceptors in the cardiorespiratory responses, aquatic surface respiration (ASR), and the development of inferior lip swelling in tambaqui during ...
