Efeitos da alimentação e digestão na contratilidade miocárdica de pítons (Python molurus)
(Universidade Federal de São Carlos, 2013-02-28)
Despite all the knowledge about the excitation-contraction coupling (E-C) in mammals, there are still large gaps in the knowledge of the cardiac myocytes physiology in other vertebrates. Thus, the study of groups underexplored ...
Efeitos da alimentação/digestão e do jejum prolongado sobre a função cardíaca de cascavéis, Crotalus durissus terrificus
(Universidade Federal de São Carlos, 2012-09-14)
Some snakes have the ability to survive long periods without food and are capable to ingest large meal size. The ingestion of proportionally large preys triggers an expressive increase on the oxidative metabolic demand ...
Efeito do envelhecimento e do treinamento resistido sobre ossos de ratos
(Universidade Federal de São Carlos, 2013-06-21)
The purpose of this study was to investigate the influence of high-intensity resistance training on the activity of bone matrix metalloproteinases (MMPs), biometric, biomechanical, biophysical and biochemical properties ...
Efeitos periféricos e centrais decorrentes da exposição à cocaína e testosterona em ratos adolescentes e adultos
(Universidade Federal de São Carlos, 2012-09-11)
Drug abuse is considered a major public health problem in the world. The use of cocaine and anabolic-androgenic steroids (AAS) has increased in Brazil. Epidemiological studies indicate that adolescents are more vulnerable ...
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 ...
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 ...
Respostas cardiorrespiratórias do teleósteo de respiração aérea, Clarias gariepinus, exposto à hipóxia gradual
(Universidade Federal de São Carlos, 2010-06-25)
Air-breathing fish are classified as obligatory (when breathing obligatory atmospheric air independently of the water O2 tension) or facultative air-breather (using an air breathing organ ABO -, when theirs gills are not ...
Localização, distribuição e orientação dos quimiorreceptores de O2 branquiais e o controle neural periférico dos reflexos cardiorrespiratórios de um teleósteo de respiração aérea, o bagre-africano, Clarias gariepinus
(Universidade Federal de São Carlos, 2014-06-30)
The African sharptooth catfish Clarias gariepinus is a facultative air-breather with the ABO present in the 2nd and 3rd gill arches. Like other bimodal respirators, the African catfish presents cardiorespiratory adjustments ...
