Avaliação pancreática de animais submetidos à dieta hiperlipídica
(Universidade Federal de São Carlos, 2012-09-04)
The pathogenesis of type 2 diabetes mellitus (DM2) is associated with insulin resistance (IR) and pancreatic β cells (β cells) defect. Adipose tissue modulates metabolism by releasing free fatty acids (FFA), ...
Expressão de miostatina e folistatina em ratos castrados submetidos a exercício
(Universidade Federal de São Carlos, 2012-07-19)
Myostatin (MSTN) is a negative regulator of skeletal muscle growth, while androgens are strong positive regulators of muscle growth and strength. Follistatin (FS) is a nonrelated protein which inhibits MSTN action. The ...
Alterações agudas no metabolismo energético de ratos submetidos ao exercício resistido em escada
(Universidade Federal de São Carlos, 2012-05-22)
Previous animal s research has shown that many protocols with aimed to mimic human exercise has been used. The endurance protocols are studied very often however, some difficulties are encountered to produce resistance ...
Participação dos neurônios noradrenérgicos da região A5 no controle cardiorrespiratório durante a hipercapnia e hipóxia em ratos
(Universidade Federal de São Carlos, 2012-06-04)
The noradrenergic A5 group is an important group of neurons located in the
ventrolateral pons and receives projections from several medullar areas related to
cardiorespiratory regulation. The A5 region contributes to the ...
Avaliação da injeção na substância cinzenta periaquedutal de agonista serotonérgico em camundongos submetidos à constrição crônica do nervo ciático : efeitos nos testes de nocicepção e ansiedade
(Universidade Federal de São Carlos, 2012-12-12)
Studies have shown that situations of anxiety/fear can inhibit nociception and serotonin (5-HT) has antinociceptive effect in the brain structures such as the periaqueductal gray matter (PAG). This work aimed to evaluate ...
Pacote de gelo e imersão em água gelada afetam o desempenho muscular e a atividade eletromiográfica
(Universidade Federal de São Carlos, 2012-03-30)
Although tissue cooling is widely used in the treatment of musculoskeletal disorders there is still controversy about its effects on muscular performance. It is important to study this issue since cooling is also combined ...
Distribuição e orientação dos quimiorreceptores de O2 branquiais em tilápia-do-Nilo (Oreochromis niloticus): controle das respostas cardiorrespiratórias à hipóxia
(Universidade Federal de São Carlos, 2012-08-31)
In fish the O2 chemoreceptors are mainly found in the gill arches and monitor the O2 tensions (PO2) of the inspired water (externally oriented) and/or the arterial blood (internally oriented). During hypoxia these receptors ...
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 ...
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 ...
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 ...
