Efeitos do exercício físico moderado e da suplementação da dieta com vitamina C no crescimento e no metabolismo de matrinxã, Brycon cephalus (Günter, 1869) (Teleostei:Characidae)
(Universidade Federal de São Carlos, 2006-04-20)
Moderate exercise training is known to enhance fish appetite, feed conversion efficiency and
growth rate. This type of exercise raises the hematocrit, thus blood hemoglobin concentration and the
oxygen carrying capacity ...
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, ...
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 ...
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 ...
Ajustes cardiovasculares em modelo experimental descerebrado, cascavel sul americana (Crotalus durissus)
(Universidade Federal de São Carlos, 2021-12-03)
The reptile class has considerable importance among vertebrates for investigations about the evolution of modulatory mechanisms in the cardiovascular system. Some cardiovascular studies have been performed with in situ ...

Modulação vascular em rã touro, Lithobates catesbeianus
(Universidade Federal de São Carlos, 2021-11-17)
Maintaining blood pressure stability is essential for cardiovascular homeostasis. Excessive fluctuations may cause deleterious problems such as vascular damage or reduction in tissue perfusion. Therefore, a series of ...
Mecanismos fisiológicos como efetores da variação individual na tolerância a fatores abióticos (temperatura e hipóxia) nos teleósteos de água doce pacu (Piaractus mesopotamicus) e tilápia-do-Nilo (Oreochromis niloticus)
(Universidade Federal de São Carlos, 2020-12-14)
The anthropic influence on the aquatic environment will be responsible for an increase in the frequency and intensity of exposure of fish to two very important stressors in the viability of these animals: temperature and ...
