Interação entre osmorreceptores e mecanismos colinérgicos e angiotensinérgicos prosencefálicos no controle da ingestão de sódio
(Universidade Federal de São Carlos, 2014-08-26)
Sodium intake is induced by facilitatory signals, such as angiotensin II (ANG II) and aldosterone. Hyperosmolarity and central cholinergic activation, classic antinatriorexigenic stimuli, also induce NaCl intake when the ...
Efeito de lipopolissacarídeo de Escherichia coli no apetite ao sódio
(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 ...
Efeito do nado sustentado sobre o metabolismo intermediário e antioxidante de matrinxã (Brycon amazonicus)
(Universidade Federal de São Carlos, 2015-02-05)
The significant increase in fish consumption in recent decades has led to considerable extractive exploitation that can bring harmful consequences to the environment and the community living the fishing sustainable ...
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 ...
Participação dos receptores purinérgicos do núcleo parabraquial lateral nas respostas cardiorrespiratórias induzidas pela hipóxia aguda e hipóxia crônica intermitente
(Universidade Federal de São Carlos, 2015-02-26)
The lateral parabrachial nucleus (LPBN) is an important area of the hindbrain circuitry involved in cardiorespiratory control. Adenosine triphosphate (ATP) is considered an important central neurotransmitter and purinergic ...
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 ...
