Participação dos receptores purinérgicos P2 no núcleo do trato solitário sobre as respostas cardiorrespiratórias induzidas por hipóxia
(Universidade Federal de São Carlos, 2015-09-18)
Cardiorespiratory responses to hypoxia are controlled by brainstem areas including the nucleus of the solitary tract (NTS). In the present study, we investigated the effects of suramin (a non-selective purinergic receptor ...
Efeitos do extrato bruto da cianobactéria Radiocystis fernandoi no teleósteo, Hoplias malabaricus
(Universidade Federal de São Carlos, 2015-05-29)
Eutrophication of the aquatic environment favors cyanobacteria blooms and
affects the biota due to organoleptic water changing and the release of toxins. The
objective of this study was to evaluate the effect of microcystin ...

(Universidade Federal de São Carlos, 2015-10-02)
It is well know that the respiratory network, undergoes significant development
in the postnatal period. Among various processes, the maturing of the catecholaminergic
(CA) system shows to be an important factor in the ...
Efeitos da microcistina-LR sobre parâmetros cardiorrespiratórios e biomarcadores do estresse oxidativo de duas espécies de teleósteos neotropicais, traíra, Hoplias malabaricus (Bloch, 1794) e matrinxã, Brycon amazonicus (Spix & Agassiz, 1829)
(Universidade Federal de São Carlos, 2015-03-10)
Cyanobacteria, under favorable conditions can form large superficial masses of green

the bloom, there may be risks of water bodies ...
Modulação autonômica cardíaca durante o exercício no peixe de respiração aérea bagre africano, Clarias gariepinus
(Universidade Federal de São Carlos, 2015-09-04)
Teleost fishes were the first vertebrates to possess double autonomic innervation of the heart,
where a balance between adrenergic and cholinergic actions determine heart rate (ƒH). Among
teleosts, air breathing (AB) ...

(Universidade Federal de São Carlos, 2015-04-01)
Aggressive interactions between conspecific animals have been used as an
ethological source of social stress to study some aspects of social anxiety. Through this
work we used a new experimental protocol in order to ...
Estudo do envolvimento da neurotransmissão CRFérgica do Núcleo Leito da Estria Terminal (NLET) nas respostas autonômicas desencadeadas pelo estresse por restrição agudo em ratos
(Universidade Federal de São Carlos, 2015-04-10)
The corticotropin-releasing factor (CRF) is involved in behavioral and physiological responses to emotional stress through its action in several limbic structures, including the bed nucleus of the stria terminalis (BNST). ...
