Lateralização funcional do córtex pré-frontal medial na ansiedade em camundongos: avaliações molecular e psicofarmacológica
(Universidade Federal de São Carlos, 2021-08-05)
The left and right medial prefrontal cortex (L & RmPFC) process emotional responses induced by stress-related stimuli, and LmPFC and RmPFC inhibition elicit anxiogenesis and anxiolysis, respectively. Here we sought to ...
Ajustes cardiovasculares em modelo experimental descerebrado, cascavel sul americana (Crotalus durissus)
(Universidade Federal de São Carlos, 2021-12-03)
The reptile class has considerable importance among vertebrates for investigations about the evolution of modulatory mechanisms in the cardiovascular system. Some cardiovascular studies have been performed with in situ ...
Envolvimento dos receptores centrais angiotensinérgicos e mineralocorticóides no aumento do apetite ao sódio induzido por privação hídrica em ratos com hipertensão renovascular
(Universidade Federal de São Carlos, 2020-04-27)
Sodium appetite in normotensive rats submitted to water deprivation (WD) for 24 h followed by 2 h with access to water only (partial rehydration–PR) depends on the activation of the renin-angiotensin system (RAS). ...
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 ...
Efeitos do treinamento aeróbio no conteúdo da proteína utrofina e nas propriedades contráteis do músculo tibial anterior de camundongos mdx: modelo experimental da Distrofia Muscular de Duchenne
(Universidade Federal de São Carlos, 2020-07-31)
Introduction: Duchenne muscular dystrophy (DMD) is the most common and severe muscular dystrophy caused by the absence of the dystrophin protein that determines, progressive loss of muscle fibers and muscle weakness. It ...
Efeitos do treinamento físico na adiposidade visceral, tecido adiposo marrom e parâmetros metabólicos de ratos Wistar alimentados com dieta hiperlipídica
(Universidade Federal de São Carlos, 2020-07-15)
Obesity is a multifactorial disease that produces various metabolic disorders through the local and systemic inflammatory response occasioned by the pathological remodeling of visceral white adipose tissue (WAT). Furthermore, ...
Avaliação funcional da interação entre os núcleos da rafe e o núcleo retrotrapezóide nas respostas ventilatórias à hipercapnia em ratos
(Universidade Federal de São Carlos, 2020-03-13)
During hypercapnia, chemosensory cells located in the brainstem are stimulated and send excitatory inputs to the respiratory network to promote an increase pulmonary ventilation. Among the candidates responsible for central ...
Recuperação espontânea, curso temporal e influência circadiana na habituação das respostas cardiovasculares ao estresse de restrição repetido em ratos
(Universidade Federal de São Carlos, 2020-04-30)
Stress is related to the development of several cardiovascular diseases. These diseases are related to morphofunctional changes that can be triggered by chronic exposure to aversive events. However, an important adaptive ...
Envolvimento de neurotransmissões angiotensinérgicas no núcleo medial da amídala nas respostas cardiovasculares e ansiogênica ao estresse de restrição em ratos
(Universidade Federal de São Carlos, 2020-09-04)
Limbic structures participate in the control of physiological responses related to stress, and the medial amigdaloid nucleus (MeA) has been demonstrated as an area of the central nervous system involved in the control these ...
Modificações ventilatórias induzidas pela hipóxia intermitente aguda em condições não anestesiadas
(Universidade Federal de São Carlos, 2020-03-27)
It has been described that intermittent hypoxia (IH, periods of hypoxia followed by normoxia), as observed in some pathological situations, promotes, acutely, a sustained increase in respiratory motor activity, dependent ...
