Participação do sistema purinérgico no locus coeruleus (LC) no controle cardiorrespiratório e térmico em normocapnia e hipercapnia em ratos não anestesiados
(Universidade Federal de São Carlos, 2011-12-14)
Locus coeruleus (LC) is considered as a chemosensitive region to CO2/pH in mammals and amphibians, mainly its noradrenergic neurons. The LC purinergic neuromodulation is of particular interest since adenosine 5′-triphosphate ...
Efeitos de uma desintegrina RGD recombinante de Rhinocerophis alternatus (Bothrops alternatus) na migração de células normais e tumorais
(Universidade Federal de São Carlos, 2011-08-03)
Cell migration, invasion of the surrounding tissues, blood vessels and proliferation are cellular processes involved in metastases. These events are mediated by integrins, adhesion receptors present on cell surfaces and ...
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 ...
Natação e treinamento de força: influências sobre a expressão gênica de TNF-alfa e IL-10, área de adipócitos e perfil lipídico em ratos obesos
(Universidade Federal de São Carlos, 2011-06-16)
The aim of the present study was to investigate the effect of swimming and resistance training exercise on adipose tissue, inflammation and lipid profile in highfat feeding rats. Wistar adult male rats were divided into 6 ...
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, ...
Efeito ansiolítico do ondansetron, antagonista dos receptores 5-HT3, injetado na amídala de camundongos submetidos à exposição e reexposição no labirinto em cruz elevado
(Universidade Federal de São Carlos, 2011-03-02)
Against of stimuli that are dangerous, animals manifest defense reactions that cause fear and anxiety. These stimuli activate the serotonergic system, which sends projections to structures involved in defense mechanisms ...
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 ...
Efeitos do treinamento resistido sobre o estresse oxidativo no fígado de ratas ovariectomizadas
(Universidade Federal de São Carlos, 2011-09-16)
Estrogen deficiency is associated with increased oxidative stress (OS), which in turn is involved in the physiopathology of diseases such as fatty liver disease (NAFLD). Resistance training (RT) may reduce the oxidative ...
Efeito da exposição à atrazina nas brânquias de curimbatá, Prochilodus lineatus (Teleósteo, Prochilodontidae)
(Universidade Federal de São Carlos, 2011-03-03)
The herbicide atrazine is one of the most common pesticides found in the aquatic ecosystems all over the world. In this study the effects of atrazine, at sublethal concentrations, were evaluated on the gills of Prochilodus ...
