Ativação do subtipo de receptor 5-HT1A do núcleo paraventricular do hipotálamo sobre a ingestão de água e sódio
(Universidade Federal de São Carlos, 2006-04-20)
Hypothalamic paraventricular nucleus (PVN) has an important role in the
hydroeletrolytic balance and it also participates in the regulation of water and sodium intake.
Recent researches described the presence of 5-HT1 ...
Efeito de um iogurte de soja suplementado com isoflavonas e com propriedades probióticas sobre o perfil lipídico e adiposidade em ratos jovens alimentados com dieta hipercolesterolêmica
(Universidade Federal de São Carlos, 2006-04-25)
This study investigated the effects of soy yogurt fermented by Enterococcus faecium CRL 183
and Lactobacillus jugurti 416 supplemented with isoflavones on adipose tissue, blood lipid,
and glucose levels on juvenile rats. ...

(Universidade Federal de São Carlos, 2009-12-17)
Lipopolysaccharide (LPS), an endotoxin derived from gram-negative bacteria wall, triggers a conjunct of systemic and behavioral responses grouped under the name of sickness behavior. Several works show the inhibition of ...
Caracterização dos quimiorreceptores de O2 envolvidos no controle dos reflexos cardio-respiratórios de trairão, Hoplias lacerdae (Teleostei, Erythrinidae) em resposta à hipóxia ambiental
(Universidade Federal de São Carlos, 2008-01-24)
The ability to sense and respond to oxygen availability in the environment is of extreme
functional importance for fish. This is even more so in tropical freshwater habitats where
environmental hypoxia can occur rapidly ...
Papel dos receptores GABA-benzodiazpínicos da amigdala na modulação da ansiedade em camundongos ingênuos e reexpostos ao labirinto em cruz elevado
(Universidade Federal de São Carlos, 2007-12-17)
Previous studies demonstrated that microinjections of midazolam (MDZ), GABAAbenzodiazepine
(BDZs) receptor agonist, into the amygdala (AMY) produce anxiolytic effects
in the elevated plus-maze (EPM) naïve-mice. During the ...
Metabolismo de carboidratos e de lipídeos durante o exercício na intensidade do limiar ventilatório e o período de recuperação de mulheres obesas
(Universidade Federal de São Carlos, 2008-06-27)
The inability to oxidize fat is a key factor in the etiology of obesity. However, improved performance and VO2max resulting from physical training leads to increased rates of oxidation of fats. Although, there is still a ...
Subtipos de receptores colinérgicos centrais envolvidos na salivação, ingestão de água e resposta pressora induzidas pela pilocarpina injetada perifericamente
(Universidade Federal de São Carlos, 2008-04-08)
The study of sialagog drugs has a relevant clinical interest for its use in
patients with reduced salivatory secretion. Cholinergic agonists are a type of
sialagog drug and pilocarpine is the most important cholinergic ...
Sensibilização cruzada entre anfetamina e nicotina: avaliação neuroquímica do núcleo acumbens e córtex préfrontal em ratos adolescentes e adultos
(Universidade Federal de São Carlos, 2009-09-24)
Nicotine and psychostimulants are often abused in combination. Drug abuse often begins during adolescence. Exposure to drugs of abuse during adolescence can have long-term consequences. We have previously demonstrated that ...
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 ...
