Mecanismos comportamentais e moleculares envolvidos na interação entre as substâncias de abuso e os fatores de risco para o desenvolvimento da dependência
(Universidade Federal de São Carlos, 2013-03-08)
Tobacco and ethanol are the most used drugs in the world and often co-abused. An important issue in the field of drug abuse research is the characterization of risk factors related to increased vulnerability to drug ...
Dimorfismo sexual da função quimiorreceptora a CO2/pH dos neurônios noradrenérgicos no Locus coeruleus
(Universidade Federal de São Carlos, 2014-04-10)
The Locus coeruleus (LC) has been suggested as a CO2 chemoreceptor site in mammals. Most of the studies involving the role of LC in hypercapnic ventilatory response have been performed in males. Since, ovarian steroids ...
Influência das águas amazônicas no compromisso osmorrespiratório em osteoglossiformes
(Universidade Federal de São Carlos, 2013-08-01)
In the Amazon basin, the Osteoglossiforme order is represented by the species Osteoglossum ferreirai, O. bicirrhosum and Arapaima gigas. Although belonging to the same order, these species show different modes of breathing; ...
Controle da ingestão de água e sódio pelos mecanismos adrenérgicos do núcleo parabraquial lateral
(Universidade Federal de São Carlos, 2013-05-17)
The activation of α2-adrenoceptors with noradrenaline injected into the lateral parabrachial nucleus (LPBN) increases 1.8% NaCl intake in rats treated with the diuretic furosemide (FURO) combined with low dose of the ...
Natriorexigênese paradoxal: núcleo parabraquial lateral e mecanismos centrais, sistêmicos e comportamentais
(Universidade Federal de São Carlos, 2013-03-22)
Sodium intake is induced by facilitatory signals, like angiotensin II and aldosterone Cell dehydration, a classical inhibitory signal for sodium intake, may also induce paradoxical sodium intake if the sodium intake ...
O papel dos receptores GABAA-benzodiazepínicos da amídala na modulação da antinocicepção e de comportamentos defensivos em camundongos submetidos ao teste de exposição ao rato
(Universidade Federal de São Carlos, 2012-12-13)
Animal models have been widely used to investigate the neurobiology of anxiety, fear and to evaluate the antinociception-induced by anxiety/fear. In this sense, the mice (prey) exposed to a predator (rat) exhibit intense ...
O ondansetron, antagonista dos receptores 5-HT3, reverte o efeito ansiolítico das injeções de midazolam no hipocampo ventral de camundongos expostos aos modelos labirinto em cruz elevado (LCE) e exposição ao rato
(Universidade Federal de São Carlos, 2012-02-10)
Animal models have often been used to investigate the neurobiology of emotional states (fear and anxiety). In this sense, the elevated plus maze (EPM) and the rat exposure test are effective to evaluate these states and ...
Efeitos da temperatura e do estado metabólico sobre a função cardíaca do jacaré-de-papo-amarelo (Caiman latirostris)
(Universidade Federal de São Carlos, 2014-01-28)
Phenomena as feeding and thermoregulation can challenge both the cardiac output and heart rate (fH). Postprandial changes in many physiological patterns are typically recorded for ectotherms, although predominantly studied ...
Avaliação dos efeitos da hidroxiapatita e do resveratrol sobre o tecido ósseo de ratos contaminados com acetato de chumbo
(Universidade Federal de São Carlos, 2013-06-21)
Lead (Pb) is an ubiquitous pollutant in the environmental ecosystem. Its distribution is mainly anthropogenic, coming from the burning of fossil fuels, mining and production of various industrial products. There is little ...
Habitat, hábito e morfologia cardíaca: influência destes fatores sobre as respostas cardiorrespiratórias à hipóxia e alterações térmicas em espécies de peixes ecologicamente distintas
(Universidade Federal de São Carlos, 2011-12-21)
Aquatic environments are subjected to wide variations in their physicochemical properties which can compromise the survival of the animals that inhabit these waters, especially the fish, which exhibit adaptive behavioral, ...
