Role of Corticosterone on Sleep Homeostasis Induced by REM Sleep Deprivation in Rats
(Public Library Science, 2013-05-07)
Sleep is regulated by humoral and homeostatic processes. If on one hand chronic elevation of stress hormones impair sleep, on the other hand, rapid eye movement (REM) sleep deprivation induces elevation of glucocorticoids ...
Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats
(Blackwell Publishing, 2008-03-01)
We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...
Physiological stress in captive Greater rheas (Rhea americana): Highly sensitive plasma corticosterone response to an ACTH challenge
(Academic Press Inc Elsevier Science, 2009-12)
Up to the present no studies have been conducted either on baseline concentrations of adrenal hormones or on hormonal responses to stress in Greater rhea (Rhea americana) and most ratite species. The aims of this work were ...
Chronic restraint or variable stresses differently affect the behavior, corticosterone secretion and body weight in rats
(Elsevier B.V., 2007-01-30)
Organisms are constantly subjected to stressful stimuli that affect numerous physiological processes and activate the hypothalamo-pituitary-adrenal (HPA) axis, increasing the release of glucocorticoids. Exposure to chronic ...
Different regulation of cortisol and corticosterone in the subterranean rodent Ctenomys talarum: Responses to dexamethasone, angiotensin II, potassium, and diet
(Academic Press Inc Elsevier Science, 2019-03)
When harmful environmental stimuli occur, glucocorticoids (GCs), cortisol and corticosterone are currently used to evaluate stress status in vertebrates, since their secretions are primarily associated to an increased ...
Genistein affects the morphology of pituitary ACTH cells and decreases circulating levels of ACTH and corticosterone in middle-aged male rats
(Sociedad de Biología de Chile, 2009)
Effect Of Embryo Thermal Stimulation On The Serum Levels Of Immunoglobulins And Corticosterone, And Organ Histopathology Of 1 Day-old Broilers
(Facta-Fundacio Arnco Ciencia Tecnologia AvicolasCampinas, 2016)
Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats
(Blackwell Publishing, 2008-03-01)
We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...
Yolk immunoreactive corticosterone does not relate with maternal fecal glucocorticoids in a captive population of Greater Rheas (Rhea americana)
(Springer, 2020-10)
Maternal corticosterone in avian egg yolks may signal and prepare offspring for the prevailing conditions. However, this adjustment requires flexible mechanisms of regulation that lead to the absence of a correlation between ...
Plasma corticosterone elevation inhibits the activation of nuclear factor kappa B (NFKB) in the Syrian hamster pineal gland
(INFORMA HEALTHCARELONDON, 2013-08-02)
We evaluated how the mild stress-induced increase in endogenous corticosterone affected the pineal gland in Syrian hamsters (Mesocricetus auratus). The animals were maintained under constant light for 1 day, instead of a ...
