Efeitos do surfactante nonilfenol etoxilado em peixes : função cardiorrespiratória e histopatologia em Tilápia-do-Nilo, Oreochromis niloticus, em condições de normóxia e hipóxia aquáticas
(Universidade Federal de São Carlos, 2018-01-26)
Nonylphenol ethoxylate (NPE) is a nonionic surfactant component of many chemical formulations. Investigations on the effects of nonylphenol ethoxylate toxicity and its derivatives on fish mostly focus on endocrine disruption, ...
O reflexo barostático em teleósteos: controle cardiorrespiratório, influência do habitat e padronização do Método da Sequência para avaliação do ganho barorreflexo
(Universidade Federal de São Carlos, 2019-03-18)
The regulation of arterial blood pressure by the baroreflex is a sine qua non condition for the maintenance of adequate tissue perfusion and for the prevention of organic lesions in most vertebrates. Fish, as well as other ...
Distribuição e orientação dos quimiorreceptores de O2 branquiais em tilápia-do-Nilo (Oreochromis niloticus): controle das respostas cardiorrespiratórias à hipóxia
(Universidade Federal de São Carlos, 2012-08-31)
In fish the O2 chemoreceptors are mainly found in the gill arches and monitor the O2 tensions (PO2) of the inspired water (externally oriented) and/or the arterial blood (internally oriented). During hypoxia these receptors ...
Respostas cardiorrespiratórias do teleósteo de respiração aérea, Clarias gariepinus, exposto à hipóxia gradual
(Universidade Federal de São Carlos, 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 nitric oxide and adrenergic stimulation on the cardiovascular adjustments in South American rattlesnakes (Crotalus durissus)
(Universidade Federal de São Carlos, 2019-05-24)
Understanding the basis of vascular tone regulation is important to comprehend the cardiovascular physiology of any vertebrate. Recent investigations on reptiles have tried that description working on anesthetized animals. ...
A influência da hipóxia severa na sensibilidade barorreflexa de tilápia-do-Nilo (Oreochromis niloticus)
(Universidade Federal de 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 ...
Efeito da variação diária na temperatura corporal no incremento metabólico pós-prandial (SDA) da espécie Lithobates Catesbeianus
(Universidade Federal de São Carlos, 2019-08-30)
Introduction: The postprandial metabolic increment is characterized by a fast elevation in postprandial metabolic rate. The increase in O2 consumption continues until reaching a peak of consumption, that may occur days ...
