Avaliação da função cardíaca do teleósteo neotropical matrinxã, Brycon amazonicus: uma análise matemática e biomolecular
(Universidade Federal de São Carlos, 2011-02-18)
The ventricular myocardial contractility of the matrinxã teleost, Brycon amazonicus, was analysed in previous experimentation with isometric multicellular preparations, in time effect and force-frequency relationship ...
Bloqueio dos receptores 5-HT2 da substância cinzenta periaquedutal suprime o efeito ansiolítico resultante do antagonismo dos receptores 5-HT1A do núcleo mediano da rafe em camundongos
(Universidade Federal de São Carlos, 2011-12-15)
Several lines of evidence support the involvement of serotonergic (5-HT) neurons of the median raphe nucleus (MRN) in anxiety-like behaviour. In this context, it is known that blockade of 5- HT1A somatodendritic autoreceptors ...
Habitat, hábito e morfologia cardíaca: influência destes fatores sobre as respostas cardiorrespiratórias à hipóxia e alterações térmicas em espécies de peixes ecologicamente distintas
(Universidade Federal de São Carlos, 2011-12-21)
Aquatic environments are subjected to wide variations in their physicochemical properties which can compromise the survival of the animals that inhabit these waters, especially the fish, which exhibit adaptive behavioral, ...
Atividade metaloproteinases e propriedades físicas, químicas e biomecânicas de ossos de ratos tratados com cloreto de mercúrio
(Universidade Federal de São Carlos, 2011-09-15)
There are few data about the mercury influence on bone metabolism them it is important to investigate the bone parameters that can be affected by it. The aim of this study was to evaluate the biometric, physical, biomechanical ...
Impacto de diferentes vias de contaminação por mercúrio inorgânico sobre os biomarcadores de estresse oxidativo, a função cardio-respiratória e o potencial de bioconcentração e biomagnificação em matrinxã, Brycon amazonicus (Spix & Agassiz, 1829) e em traíra, Hoplias malabaricus (Bloch, 1794)
(Universidade Federal de São Carlos, 2011-06-20)
Both the mercury (Hg) and their compounds are recognized as important pollutants, because they are persistent, bioaccumulative and toxic. The largest sources of mercury pollution are chloride-alkaline industry and gold ...
Repercussões do treinamento resistido periodizado e destreinamento sobre o perfil funcional de mulheres idosas
(Universidade Federal de São Carlos, 2011-12-19)
Proposed in the middle 80's from the concepts of "classic" periodization sports training, the periodization of resistance training (PER) has become popular in recent years. The concept of the PER refers as planned and ...
Estudos hematológicos e caracterização estrutural e funcional das hemoglobinas do peixe pulmonado Lepidosiren paradoxa (Dipnoi, Fitzinger, 1837) e do peixe de respiração aérea facultativa Hoplerythrinus unitaeniatus (Characiformes, Spix, 1829)
(Universidade Federal de São Carlos, 2011-08-01)
The blood cell composition in their qualitative and quantitative aspects as well as the functional properties of hemoglobin (Hb) shows characteristic of adaptation to the aquatic environment, aiding the understanding of ...
Crescimento, hematologia e metabolismo de pacu (Piaractus mesopotamicus) submetido ao exercício aeróbico e alimentado com níveis crescentes de proteínas
(Universidade Federal de São Carlos, 2011-05-24)
The composition of the diet, the metabolic adaptations and variations in the activity of the fish are the main factors responsible for seasonal changes in physiological variables. It is known that aerobic exercise can ...
