Chronic unpredictable mild stress alters an anxiety-related defensive response, Fos immunoreactivity and hippocampal adult neurogenesis
(Amsterdam, 2013-08-01)
Previous results show that elevated T-maze (ETM) avoidance responses are facilitated by acute restraint. Escape, on the other hand, was unaltered. To examine if the magnitude of the stressor is an important factor influencing ...
Effect of sex chromosome complement on sodium appetite and Fos-immunoreactivity induced by sodium depletion.
(American Journal of Physiology-Regulatory, Integrative and Comparative Physiology., 2014)
Effect of sex chromosome complement on sodium appetite and Fos-immunoreactivity induced by sodium depletion. Am J Physiol
Regul Integr Comp Physiol 306: R175–R184, 2014. First published November 20, 2013; doi:10.1152/aj ...
Unpredictable chronic mild stress exerts anxiogenic-like effects and activates neurons in the dorsal and caudal region and in the lateral wings of the dorsal raphe nucleus
(Elsevier B. V., 2015-10-17)
In previous studies, we verified that exposure to unpredictable chronic mild stress (UCMS) facilitates avoidance responses in the elevated T-maze (ETM) and increased Fos-immunoreactivity in different brain structures ...
Effect of sex chromosome complement on sodium appetite and Fos-immunoreactivity induced by sodium depletion
(American Physiological Society, 2013-11)
Previous studies indicate a sex chromosome complement (SCC) effect on the angiotensin II-sexually dimorphic hypertensive and bradycardic baroreflex responses. We sought to evaluate whether SCC may differentially modulate ...
Pontomedullary and hypothalamic distribution of Fos-like immunoreactive neurons after acute exercise in rats
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-06-02)
During exercise, intense brain activity orchestrates an increase in muscle tension. Additionally, there is an increase in cardiac output and ventilation to compensate the increased metabolic demand of muscle activity and ...
Tryptophan overloading activates brain regions involved with cognition, mood and anxiety
(Acad Brasileira de Ciências, 2017)
Tryptophan is the only precursor of serotonin and mediates serotonergic activity in the brain. Previous studies have shown that the administration of tryptophan or tryptophan depletion significantly alters cognition, mood ...
Prolonged consumption of soy or fish-oil-enriched diets differentially affects the pattern of hypothalamic neuronal activation induced by refeeding in rats
(MANEY PUBLISHING, 2009)
We used c-Fos immunoreactivity to estimate neuronal activation in hypothalamic feeding-regulatory areas of 3-month-old rats fed control or oil-enriched diets (soy or fish) since weaning. While no diet effect was observed ...
A modified rat model of neonatal anoxia: Development and evaluation by pulseoximetry, arterial gasometry and Fos immunoreactivity
(ELSEVIER SCIENCE BV, 2011)
Neonatal anoxia is a worldwide clinical problem that has serious and lasting consequences. The diversity of models does not allow complete reproducibility, so a standardized model is needed. In this study, we developed a ...
Maternal separation in early life modifies anxious behavior and Fos and glucocorticoid receptor expression in limbic neurons after chronic stress in rats: Effects of tianeptine.
(Taylor & Francis Ltd, 2016-01)
Early-life adversity can lead to long-term consequence persisting into adulthood. Here, we assess the implications of an adverse early environment on vulnerability to stress during adulthood. We hypothesized that the ...
