Salmonella Enteritidis infection, corticosterone levels, performance and egg quality in laying hens submitted to different methods of molting
(2019-10-01)
In commercial layer poultry farming, molt induction is an important tool used by egg producers to prolong the production cycle of laying hens. Conventional molt induction programs involve total feed withdrawal, which raises ...
Effect of maternal environment on yolk immunoreactive corticosterone and its influence on adrenocortical and behavioral activity in chicks of Greater Rhea (Rhea americana)
(Elsevier, 2019-08)
Maternal corticosterone in avian eggs may modify offspring phenotype in order to increase survival in poor environments. In the Greater Rhea (Rhea americana), we previously found that yolk immunoreactive corticosterone is ...
Increased corticosterone levels in mice subjected to the rat exposure test
(Academic Press Inc. Elsevier B.V., 2010-02-01)
In recent years, there has been a notable interest in studying prey-predator relationships to develop rodent-based models for the neurobehavioral aspects of stress and emotion. However, despite the growing use of transgenic ...

Regulation of corticosterone function during early weaning and effects on gastric cell proliferation
(ElsevierBurbank, 2014-03)
Objectives: The development of the gastrointestinal tract depends on many elements, including glucocorticoids. In the current study, we evaluated the effects of early weaning on corticosterone function and the growth of ...
Differential behavioral and neuroendocrine effects of repeated nicotine in adolescent and adult rats
(Elsevier B.V., 2005-03-01)
Despite the high prevalence of tobacco abuse among adolescents, the neurobiology of nicotine addiction has been studied mainly in adult animals. Repeated administration of this drug to adult rats induces behavioral ...

24-hour changes in ACTH, corticosterone, growth hormone, and leptin levels in young male rats subjected to calorie restriction
(Taylor & Francis, 2005-12)
Calorie restriction of young male rats increases plasma prolactin, decreases luteinizing hormone (LH) and testosterone, and disrupts their 24 h secretory pattern. To study whether this could be the consequence of stress, ...
Corticosterone evaluation in Wistar rats infected with the Y strain of Trypanosoma cruzi during the chronic phase
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Understanding the mechanisms responsible for mediating the effects of stress on Trypanosoma cruzi infection is crucial for determining the full impact of stress on Chagas` disease and for devising effective interventions. ...
Sex-specific brain erythropoietin regulation of mouse metabolism and hypothalamic inflammation
(American Society for Clinical Investigation, 2020)
The blood hormone erythropoietin (EPO), upon binding to its receptor (EpoR), modulates high-fat diet-induced (HFO-induced) obesity in mice, improves glucose tolerance, and prevents white adipose tissue inflammation. ...
