Efeitos da microcistina-LR (Microcystis aeruginosa) sobre parâmetros cardio-respiratórios de tilápia-do-nilo (Oreochromis niloticus)
(Universidade Federal de São Carlos, 2010-06-23)
Cyanobacteria, in favorable conditions can form large superficial masses of green color called blooms. Some genera of cyanobacteria are producing toxins, and during the bloom, there may be risks of contamination of water ...
Efeitos da acidose lática nos processos da contratilidade cardíaca do teleósteo de água doce matrinxã, Brycon cephalus
(Universidade Federal de São Carlos, 2009-08-28)
In the majority of the fish species already studied, cardiac force contraction is sensitive to small changes in the extracellular pH. During intense swimming, the increased lactic acid (LA) levels significantly reduce the ...
Gavagem de NaCl hipertônico induz ingestão de bicarbonato de sódio
(Universidade Federal de São Carlos, 2009-05-17)
The literature shows that gavage of 2 M NaCl, a method to induce cell dehydration, induces water and 0.15 M NaCl intake in a two-bottle test. However, the hypertonic NaCl is also known as a mild gastric irritant, which ...
Efeitos da ovariectomia e treinamento resistido na atividade da metaloproteinase-2 no tendão calcâneo de ratas
(Universidade Federal de São Carlos, 2010-03-12)
Tendons remodeling relies upon extracellular matrix restructuring by the matrix metalloproteinases (MMPs). The aim of this study was to investigate MMP-2 activity in different regions of the calcanear tendon after resistance ...
Toxicidade aguda, efeitos metabólicos e hematológicos subletais do fenol em pacu Piaractus mesopotamicus (Holmberg, 1887)
(Universidade Federal de São Carlos, 2008-11-25)
Phenol compounds and their derivatives are usually found in wastewaters. They may rise in aquatic environments from industry, sewage and country-farm wastes. In the present study we intended to determine the acute toxicity ...
Efeito da ovariectomia e treinamento de força no conteúdo lipídico no músculo esquelético, fígado, coração, depósitos de gordura e perfil lipídico
(Universidade Federal de São Carlos, 2010-03-12)
The aim of the present study was to investigate the effects of resistance training on skeletal muscle lipid content, liver lipid content, heart lipid content, fat depots and lipid profile in ovariectomized rats. Wistar ...
Efeito do extrato bruto e da fração alcaloídica de Erythrina velutina em camundongos submetidos ao labirinto em cruz elevado e ao modelo de esquiva inibitória do tipo descida da plataforma
(Universidade Federal de São Carlos, 2009-08-11)
In the popular therapy Erythrina velutina (EV), plant family Fabaceae, is used as an analgesic, anticonvulsant, anxiolytic or sedative and combating insomnia. Previous studies performed in rodents suggest that extracts of ...
Respostas adaptativas de matrinxã (Brycon amazonicos, (Spix & Agassiz 1829) submetido a diferentes regimes de atividade de natação aeróbica
(Universidade Federal de São Carlos, 2010-09-24)
The exercise training has been highlighted by the effects that they produce directly on the animal physiology. In fishes, there is evidence that the practice of forced swimming brings improvements in growth rates, feed ...
Envolvimento de receptores muscarínicos centrais no controle da ingestão de sódio
(Universidade Federal de São Carlos, 2017-07-10)
Water and sodium intake are fundamental behaviors for body fluid homeostasis. These behaviors are controlled by a neural circuitry involving facilitatory and inhibitory mechanisms, which are modulated by signals activated ...
Efeito do bloqueio dos receptores mineralocorticoides da região infra-límbica do córtex pré-frontal medial sobre a tolerância aos efeitos do midazolam em camundongos submetidos ao protocolo de teste e reteste no labirinto em cruz elevado
(Universidade Federal de São Carlos, 2017-05-25)
Several studies have shown that the previous experience (trial 1) to the elevated plus-maze
(EPM) increases the avoidance of the open arms and impairs the anxiolytic-like effect of
midazolam (MDZ), a benzodiazepine-GABAA ...
