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 ...
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 ...
Ingestão e palatabilidade ao sódio relacionados aos mecanismos inibitórios do núcleo parabraquial lateral em modelos de desidratação intracelular e extracelular
(Universidade Federal de São Carlos, 2019-09-06)
Several evidences correlate excessive salt intake with the development or aggravation of chronic diseases, including hypertension and cerebrovascular diseases. One factor that could contribute to excessive salt intake is ...
