Importância do núcleo parabraquial lateral no controle do equilíbrio hidromineral em modelo animal de hipertensão essencial
(Universidade Federal de São Carlos, 2018-07-05)
Excessive salt intake has been associated with the development or worsening of chronic diseases such as hypertension. Spontaneously hypertensive rats (SHR) have a typical increased sodium preference. The lateral parabrachial ...
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 ...
Especificidade do apetite ao sódio: uma possível contribuição hormonal
(Universidade Federal de São Carlos, 2006-08-24)
The hypothesis of a synergy between two hormones responsible for sodium
conservation, aldosterone and angiotensin II (ANG II), explains the expression of a
characteristic of sodium appetite, hypertonic NaCl intake, in a ...
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 ...
O sistema renina-angiotensina e a palatabilidade do sabor salgado em ratos com apetite ao sódio
(Universidade Federal de São Carlos, 2020-05-08)
The renin-angiotensin system (RAS) belongs to mechanisms that control the search and ingestion of hypertonic NaCl in rats with sodium apetite. Here we investigate whether the antagonism of RAS affects hedonic and aversive ...
Influência dos hormônios sexuais nas respostas ventilatórias, termorreguladoras e na concentração de monoaminas de ratos e ratas
(Universidade Federal de São Carlos, 2019-08-29)
Evidences in the literature show differences between sexes in the control of ventilation and in the prevalence of respiratory disorders such as sleep apneas or hypopneas, that occurs three times more in men than women. ...
O tratamento crônico com fluoxetina reverte os efeitos nociceptivo e antinociceptivo induzidos pela ativação dos receptores 5-HT1A e 5-HT2C da amídala de camundongos confinados aos braços do labirinto em cruz elevado
(Universidade Federal de São Carlos, 2019-05-31)
Several studies indicate that anxiety and depression may be accompanied by symptoms of severe pain with no precise location or apparent lesions. Several evidences demonstrate that some antidepressive drugs used in the ...
Participação dos receptores opióides mu e kappa da substância cinzenta periaquedutal na febre induzida por estresse de contenção
(Universidade Federal de São Carlos, 2016-07-15)
The endogenous opioids are involved in analgesia, thermoregulation and physiological responses to various stressful stimuli such as infection, psychological stress and hypoxia. The mu and kappa receptors in the hypothalamus ...
Comportamento defensivo, prejuízo na memória e ativação diferencial do hipocampo dorsal e ventral em camundongos machos submetidos ao protocolo de derrota social
(Universidade Federal de São Carlos, 2021-11-26)
The hippocampus (HPC) is a brain area well known to regulate memory and spatial navigation but also known to be a very plastic brain structure that is influenced by other areas like the medial prefrontal cortex (mPFC) as ...
Os sistemas serotonérgico, gabaérgico e endocanabinoide da amígdala medeiam a empatia relacionada à nocicepção em camundongos
(Universidade Federal de São Carlos, 2020-08-28)
Evidence shows a reciprocal relationship between chronic pain and emotional disorders, exacerbating the other's experience. The affective-emotional component of pain can be activated not only in those who feel the pain but ...
