Efeitos da abolição da bradicardia reflexa nas respostas cardiorrespiratórias de tambaqui, Colossoma macropomum (Cuvier, 1818), em hipóxia severa: vagotomia versus inibição farmacológica
(Universidade Federal de São Carlos, 2013-06-14)
Hypoxic bradycardia is a reflex response to hypoxia observed in most fish species studied so far. This reflex is initiated by the stimulation of O2 chemoreceptors and induced by an increase in the inhibitory vagal tonus. ...
Efeito do treinamento resistido sobre a atividade enzimática da MMP-2 e antioxidantes no ventrículo esquerdo de ratos obesos
(Universidade Federal de São Carlos, 2013-03-22)
Obesity is associated with increased lipid peroxidation in the myocardium and an increased susceptibility to oxidative damage, which can lead to several cardiovascular risk factors including heart failure, insulin resistance, ...
Efeitos de nanopartículas de ouro sobre o tecido ósseo, rim, fígado e coração de ratos
(Universidade Federal de São Carlos, 2013-07-05)
The process of formation and remodeling of bone tissue is influenced by several factors such as hormones, nutrition, genetics, sex, age, intercurrent disease and environmental factors. There are published reports of the ...
Efeitos preventivos do exercício resistido na expressão de proteínas envolvidas na atrofia muscular em ratos tratados com dexametasona
(Universidade Federal de São Carlos, 2013-03-25)
Dexamethasone (Dexa) has been widely used as anti-inflammatory and anti-allergic treatment, however, its chronic use provokes peripheral insulin resistance, hypertension, weight loss and muscle atrophy. Low intensity aerobic ...

(Universidade Federal de São Carlos, 2013-06-28)
Atrazine is an herbicide widely used in agriculture, cause morphological and biochemical changes in organs of many species. The estuarine environments are highly dynamic under constant variations of physicochemical water. ...
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 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 ...
Administração intracerebroventricular de peróxido de hidrogênio: efeitos sobre a ingestão de água, excreção renal e alterações cardiovasculares induzidas por aumento da osmolaridade plasmática
(Universidade Federal de São Carlos, 2013-05-13)
The reactive oxygen species (ROS), produced endogenously in central areas may act by modulating autonomic and behavioral responses. Recent studies have shown that a reactive oxygen species, hydrogen peroxide (H2O2), injected ...
Efeito do treinamento resistido na avaliação da composição corporal e na atividade da MMP-2 nos músculos bíceps e gastrocnêmio de ratos obesos
(Universidade Federal de São Carlos, 2013-04-05)
The aim of the present study was to investigate the influence of resistance training on body composition and active matrix metalloproteinases 2 (MMP-2) on biceps and gastrocnemius muscles in rats with high fat diet. We ...
