Efeito do extrato bruto e da fração alcaloídica de Erythrina velutina em camundongos submetidos ao labirinto em cruz elevado e ao modelo de esquiva inibitória do tipo descida da plataforma
(Universidade Federal de São Carlos, 2009-08-11)
In the popular therapy Erythrina velutina (EV), plant family Fabaceae, is used as an analgesic, anticonvulsant, anxiolytic or sedative and combating insomnia. Previous studies performed in rodents suggest that extracts of ...
Gavagem de NaCl hipertônico induz ingestão de bicarbonato de sódio
(Universidade Federal de São Carlos, 2009-05-17)
The literature shows that gavage of 2 M NaCl, a method to induce cell dehydration, induces water and 0.15 M NaCl intake in a two-bottle test. However, the hypertonic NaCl is also known as a mild gastric irritant, which ...
Efeitos da ovariectomia e treinamento resistido na atividade da metaloproteinase-2 no tendão calcâneo de ratas
(Universidade Federal de São Carlos, 2010-03-12)
Tendons remodeling relies upon extracellular matrix restructuring by the matrix metalloproteinases (MMPs). The aim of this study was to investigate MMP-2 activity in different regions of the calcanear tendon after resistance ...
Respostas adaptativas de matrinxã (Brycon amazonicos, (Spix & Agassiz 1829) submetido a diferentes regimes de atividade de natação aeróbica
(Universidade Federal de São Carlos, 2010-09-24)
The exercise training has been highlighted by the effects that they produce directly on the animal physiology. In fishes, there is evidence that the practice of forced swimming brings improvements in growth rates, feed ...
Efeitos da desconexão hipotalâmica aguda e crônica sobre as respostas pressoras induzidas pela injeção central de salina hipertônica, carbacol e angiotensina II em ratos.
(Universidade Federal de São Carlos, 2005-09-24)
Several anatomical and functional studies have demonstrated that the paraventricular nucleus of the hypothalamus (PVN) constitutes a neuroendocrine center. The PVN is intimately related to the regulation of the sympathetic ...
Contribuição relativa do cálcio extracelular e do retículo sarcoplasmático para o desenvolvimento de força de contração cardíaca de jeju, Hoplerythrinus unitaeniatus.
(Universidade Federal de São Carlos, 2005-12-19)
The present study anlyzed the in vivo and in vitro responses of the ventricular myocardium obtained from Hoplerythrinus unitaeniatus acclimated and tested at 25 ºC. The in vivo heart rate (fH bpm) was obtained (ECG ...

(Universidade Federal de São Carlos, 2007-03-14)
Important researches had shown the benefits of resistance training programs
for rehabilitation as well as prophylaxis of physical incapacity. However few studies had
investigated the responses of the intermediate metabolism ...
Avaliação do papel dos receptores 5-HT3 da substância cinzenta periaquedutal de camundongos submetidos ao labirinto em cruz elevado
(Universidade Federal de São Carlos, 2009-04-24)
The exposure of animals to aversive situations, such as elevated plus-maze (EPM), activates serotonergic pathways with projections into structures involved in the defense system, such as the amygdala, septum, hypothalamus, ...
Avaliação do papel dos receptores 5-ht2 da substância cinzenta periaquedutal de camundongos submetidos ao labirinto em cruz elevado
(Universidade Federal de São Carlos, 2008-03-28)
It is widely acknowledged that the indoleamine neurotransmitter serotonin (5-HT)
plays a dual role in the regulation of anxiety, a role that in part depends upon neuroanatomical
locus of action. Thus, whereas stimulation ...
O papel dos receptores 5-HT3 da amídala na modulação da ansiedade em camundongos expostos ao labirinto em cruz elevado
(Universidade Federal de São Carlos, 2010-05-07)
Aversive situations may activate the serotonergic system, which, in turn, emit projections to structures involved in the defense mechanisms such as: septum, hypothalamus, hippocampus, periaqueductal gray and amygdala, ...
