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, ...
Envolvimento das espécies reativas de oxigênio e das citocinas na hipertensão
(Universidade Federal de São Carlos, 2017-03-23)
Arterial hypertension (AH) is a multifactorial disease, characterized by increased levels of arterial pressure (AP) that causes an increased risk of coronary disease, stroke and congestive heart failure. Several studies ...
O comportamento respiratório e a cascata de O2 no cascudo de respiração bimodal Pterygoplichthys anisitsi (Teleostei, Loricariidae)
(Universidade Federal de São Carlos, 2007-04-26)
The condition of poor oxygen, called hypoxia, can affect aquatic environments.
Their cause can be natural or, more frequently, a consequence of anthropogenic action.
Among fish, the Siluriformes group (catfishes and ...
Efeitos do exercício físico moderado e da suplementação da dieta com vitamina C no crescimento e no metabolismo de matrinxã, Brycon cephalus (Günter, 1869) (Teleostei:Characidae)
(Universidade Federal de São Carlos, 2006-04-20)
Moderate exercise training is known to enhance fish appetite, feed conversion efficiency and
growth rate. This type of exercise raises the hematocrit, thus blood hemoglobin concentration and the
oxygen carrying capacity ...
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 ...
Efeitos da restrição alimentar sobre marcadores bioquímicos da remodelação óssea e sobre as propriedades biométricas, biofísicas, densitométricas, bioquímicas e biomecânicas de fêmures e vértebras de ratos de diferentes idades
(Universidade Federal de São Carlos, 2016-08-12)
The food restriction promotes adaptive mechanisms that have beneficial effects on
diseases and longevity. Also, bone is target of effects provided by the reduction of diet
intake. However, there are controversies about ...
Influência do ambiente aversivo na resposta nociceptiva de ratos : um estudo sobre o papel de receptores opióides e canabinóides
(Universidade Federal de São Carlos, 2009-12-11)
In innate or learned threatening situations, animals display a set of defensive behaviors specie-specific such as autonomic alterations, flight, fight and antinociception. Exposure of mice to open elevated plus-maze (oEPM: ...
Investigação dos mecanismos neurobiológicos envolvidos nas propriedades reforçadoras, sensibilização locomotora e reinstalação da autoadministração de etanol
(Universidade Federal de São Carlos, 2018-10-26)
Alcohol is the most consumed drug in Brazil and in many other countries in the world. The high rate of relapse in alcohol-dependent individuals remains a central challenge for treating alcoholism. Several studies in human ...
Estudo do efeito da Alternagina-C, uma desintegrina do veneno de Bothrops alternatus e de um peptídeo sintético derivado de sua estrutura, sobre a expressão de fatores de crescimento, angiogênese e cicatrização de lesão em pele de rato
(Universidade Federal de São Carlos, 2008-05-07)
Angiogenesis and wound repair are mediated by several growth factors that are strictly released. Alternagin-C (ALT-C), a disintegrin-like protein from the venom of Bothrops alternatus induces in vivo angiogenesis as well ...
Remodelamento do miocárdio no exercício com componente anaeróbico.
(Universidade Federal de São Carlos, 2004-10-29)
The extracellular matrix (ECM) components are continuously synthesized and degraded
at distinct rates in a process called remodeling involving the expression of matrix
metallopeptidases (MMPs) and their inhibitors (TIMPs) ...
