1. Evaluation of a rat model of exercise-induced fatigue using treadmill running with progressively increasing load
Abstract: The mechanism behind exercise-induced fatigue is a significant topic in the field of sports physiology. Therefore, establishing and evaluating an acute exercise-induced fatigue animal model that explores the limits of the motor system may provide greater insight into these mechanisms. Heart rate is an important quantitative parameter that accuratel

2. ACUTE EFFECT OF DIFFERENT TYPES OF EXERCISE ON NATRIURETIC PEPTIDES OF WISTAR RATS
RESUMO Introdução: O estudo dos efeitos de diferentes tipos de exercício físico na fisiologia cardiovascular está aumentando na literatura. Os muitos mecanismos de controle hemodinâmico incluem a liberação atrial de peptídeos natriuréticos. Embora amplas evidências demonstrem seus efeitos agudos e o aumento na sua concentração plasmática, não

3. Effects of Copaiba oil in the healing process of urinary bladder in rats
ABSTRACT Introduction The appropriate closure of the urinary bladder is important to many urologic procedures to avoid the formation of fistulas and strictures by excessive fibrosis. This paper presents the alterations in the bladder healing process of rats after the topical use of Copaiba oil (Copaifera reticulata). Material and Methods Ten male Wistar ra

4. POD-1/Tcf21 overexpression reduces endogenous SF-1 and StAR expression in rat adrenal cells
During gonad and adrenal development, the POD-1/capsulin/TCF21transcription factor negatively regulates SF-1/NR5A1expression, with higher SF-1 levels being associated with increased adrenal cell proliferation and tumorigenesis. In adrenocortical tumor cells, POD-1 binds to the SF-1 E-box promoter region, decreasing SF-1 expression. However, the modulation of

5. Efeitos da restrição proteica gestacional em hipocampo de ratos machos adultos : avaliação da estrutura dendrítica tridimensional, do comportamento e de componentes neuroquímicos = Effects of gestational protein restriction in hippocampus of adult male rats / Effects of gestational protein restriction in hippocampus of adult male rats : evaluation of three-dimensional dendritic structure of hippocampal neurons, behavior and neurochemical components
Studies have demonstrated that maternal nutritional restriction during pregnancy or in early postnatal life results in hippocampus cognitive impairment and structural abnormalities in the 16-wk-old offspring. In an attempt to analyze whether gestational protein restriction might induce learning and memory impairment associated with structural changes in the

6. Dinâmica do sistema córtico-hipocampal durante o condicionamento contextual de medo / Cortico-hippocampal system dynamics during contextual fear conditioning
O estabelecimento das memórias de longo prazo requer uma efetiva comunicação do hipocampo com o neocortex. Um mecanismo plausível envolvido na comunicação neuronal e na plasticidade sináptica é a sincronização da atividade elétrica cerebral na frequência teta. Estudos recentes mostraram que a sincronização entre os ritmos teta do hipocampo e do

7. Evolução temporal dos efeitos do treinamento aeróbio sobre o conteúdo de ácido g-aminobutírico e glutamato em áreas de controle autonômico de ratos normotensos e hipertensos. / Temporal evolution of the effects of aerobic training on the content of g-aminobutyric acid and glutamate in areas of autonomic control of normotensive and hypertensive rats.
A hipertensão arterial cursa com hiperativação de neurônios glutamatérgicos (excitatórios) e depressão de neurônios gabaérgicos (inibitórios) em áreas centrais autonômicas. Avaliamos em ratos SHR e WKY os efeitos temporais do treinamento aeróbio (T) sobre a expressão/funcionalidade das vias gabaérgicas e glutamatérgicas no núcleo paraventric

8. Dynamics of mother-pup interactions: tradeoff between environment and physiology
The emergence and maintenance of maternal behavior are under the influence of environmental cues such as light and dark periods. This article discusses the characteristic neurobiology of the behavioral patterns of lactating rats. Specifically, the hormonal basis and neurocircuits that determine whether mother rats show typical sequential patterns of behavior

9. Therapeutic dose of Ginkgo biloba extract 761 may alter the urine excretion of Wistar rats
Wistar rats (n=20) were divided in two groups: G1 received 2 mg/kg of GBE (Ginkgo biloba extract 761), whereas G2 received the same volume of a sodium chloride solution (0.9%), both for 10 days. After a 7-day interval, the treatment was repeated for 8 days. Urine volume and food and water intake were measured daily during this protocol. Histological assessme

10. Efeitos da suplementação de zinco e do treinamento físico sobre o controle de peso e o metabolismo glicêmico em ratas ovariectomizadas
It is common to observe menopausal metabolic disorders that lead to weight gain and changes in glycemic control. Physical activity and zinc supplementation have been suggested as interventions to prevent weight gain and glucose metabolism disorders. Thus, this study aims to assess the effects of physical training and zinc supplementation on carbohydrate meta

11. Efeitos do exercício físico prévio sobre a função renal, disfunção autonômica e atividade nervosa simpática renal no diabetes mellitus experimental, em ratos / Effects of previous exercise on renal function, autonomic dysfunction and renal sympathetic nerve activity in experimental diabetes, in rats
Background: The exercise training (ET) has been recognized as an important therapeutic intervention for the chronic degenerative diseases such as Diabetes Mellitus (DM) that cause renal and cardiovascular complications. However, little is known if previous ET intervention modulates the physiological and medical impact caused by these dysfunctions. We investi

Imunodetecção do receptor metabotrópico mGluR8 no núcleo arqueado do hipotálamo de ratos Wistar e estudo dos efeitos, no receptor, resultantes da exposição oral sub-crônica ao glutamato monossódico / Imunodetecction of mGluR8 receptor in the arcuate nucleus of the hypothalamus of Wistar rats and study of the effects, on the receptor, resulting from sub-chronic exposure to monosodium glutamate
Food is part of human culture not only associated to physiological needs. Food is composed of several molecules among them amino acids. Glutamate (GLU) is the anion of one of the main amino acids found in foods that, besides being part of the food composition, is a molecule essential for human physiology. It can also be ingested due to the use of the food ad
