"""Le Cort Mantel"" and ""Mottuls Saga"": A literary comparison"
… is a literary comparison of the Old French Le cort mantel, also entitled Le mantel mautaillie, and Mottuls saga, an adaptation into Old Norse made by an unknown writer working for King Hakon (1217-1263).

Stress Ecology of the Pacific Rattlesnakes (Crotalus oreganus and Crotalus helleri)
… conditions and is modulated by the glucocorticoid hormone corticosterone (CORT) in reptiles. Stressors can have various impacts on vertebrate trait expression and may affect survival or reproduction. Little is known about the effects of chronically elevated CORT in free-ranging reptiles, …

The effects of stress hormones on preferences for acoustic signals in female green treefrogs (Hyla cinerea) and barking treefrogs (Hyla gratiosa)
… that circulating stress hormones (i.e., glucocorticoids) may mediate such effects, but this idea remains largely unexplored. I examined how circulating glucocorticoids affect preferences for male advertisement calls in female green treefrogs, <italic>Hyla cinerea<italic>, and barking …

Stress, sexual signaling, and alternative mating tactics in male green treefrogs, Hyla cinerea
… that stimulate production of the stress hormone corticosterone (CORT) in vocal competitors, suggesting a role of CORT in intrasexual competition. I predicted that modulation of CORT level during intraspecific contests plays a pivotal role in regulating the expression of male courtship signals and …

Exploring a technology-facilitated part-complete solution method for learning computer programming
… a technology supported “COde Restucturing Tool” CORT, was then designed around the learning framework and developed to support the part-complete solution method and provide a suitable learning environment. A quasi-experimental research design framework was utilised in the study which used both …

Effects of Anthropogenic Environmental Stressors on Amphibian Immune Defenses and Host-Pathogen Interactions Across Temperate and Tropical Systems
… stress responses are governed by glucocorticoids, which are responsible for homeostasis, resource allocation, and remobilization of energy stores, but can also directly and indirectly impact host immune function. Amphibians are the most threatened vertebrate taxon, in part because of …

The developmental role and regulation of the Anaphase-Promoting Complex/Cyclosome in Drosophila meiosis
… well as its fertilization. The Drosophila gene cortex (cort), a putative female meiosis-specific APC/C activator, provides a unique opportunity to study the role of the APC/C in metazoan meiosis. We demonstrate that CORT protein associates with the core APC/C in ovaries, confirming its function …

The crucial role of reelin in a preclinical model of depression
… episode relapses. Rats treated for 21 days with corticosterone (CORT), a well characterized model of depression, exhibit a depression-like phenotype. Additionally, CORT treated rats have shown a downregulation in reelin. Reelin is a large glycoprotein that has been implicated in many psychiatric …

Testosterone’s regulation of the HPA axis differs for adolescent and adult male rats
Stress hormones such as corticosterone (CORT), enables rodents to cope and meet the demands of their environment. In adult male rats, CORT release in response to stressors is dampened by the gonadal hormone testosterone. Adolescent male rats secrete more CORT in response to stressors than do adults …

Hormonally mediated maternal effects in birds
… of the primary avian stress hormone, corticosterone, to developing embryos. We currently lack information on the extent to which conditions in the maternal environment are transmitted to the offspring in birds via egg compositional changes. It is possible that maternally derived …

Seasonal Variation in Corticosterone, Stress Responses, and Physiology in the Northern Cardinal <i>Cardinalis cardinalis</i>
<p>Seasonal regulation of the adrenocortical response (e.g., ‘stress response’) appears to be ubiquitous in mid- to high-latitude vertebrates. Northern Cardinals (Cardinalis cardinalis) are a Temperate dwelling passerine of Tropical-descent with a wide species range (tropics to Northern Temperate …

The impact of urban centers on American goldfinches (Spinus tristis) overwintering at high latitudes
… to sample baseline and stress-induced plasma corticosterone (CORT) levels. Analyses revealed no interaction of latitude and urbanization in the winter distribution of American Goldfinches. Similarly, CORT concentrations did not differ between individuals trapped in urban and rural settings. It …

The glutamate hypothesis of depression: the effect of stress and glucocorticoids on glutamate synapse and the action of antidepressants
… different types of environmental stress and glucocorticoid administration affect glutamate transmission and exert structural brain remodeling in the same areas involved in human pathology. These effects of stress and glucocorticoids have been associated with the onset and exacerbation of …

Sex Ratios and the City: Is parental corticosterone a mediator of the relationship between urbanization and offspring sex allocation?
… parental condition, and sex ratios is corticosterone (CORT), the primary glucocorticoid in birds. However, no research has examined the links between urbanization, individual condition, CORT, and adaptive sex allocation within the same study. Furthermore, research that has examined …

COMPARATIVE EVALUATION OF 1H NMR SPECTROSCOPY AS A NOVEL TOOL FOR ASSESSING STRESS WITH TRADITIONAL METHODS OF BLOOD CORTICOSTERONE LEVELS AND HETEROPHIL LYMPHOCYTE RATIO IN BROILER CHICKENS (GALLUS DOMESTICUS)
… accepted indicators of stress being elevated corticosterone (CORT) and increased circulating heterophil/lymphocyte (H/L) ratios. The lack of consistency between studies measuring CORT and H/L ratios results in some skepticism when using them to quantify stress and animal welfare in the poultry …

Hormones and cooperative behaviours in the Damaraland mole-rat (Fukomys damarensis)
… investigate the effects of two steroid hormones, Cortisol (CORT) and Testosterone (T), in the regulation of cooperative behaviours in the Damaraland mole-rat (Fukomys damarensis). Because these hormones are susceptible to both modulate and be modulated by cooperative contributions, I …

Unraveling the interaction between hormones and incubation temperature on lizard cognition
… how prenatal thermal environment and corticosterone (CORT) - a key stress hormone in reptiles - affects cognitive development in two species of skinks: the delicate skink (Lampropholis delicata), and the common garden skink (L. guichenoti). I manipulated egg CORT levels and incubation …

Glucocorticoid physiology and behavior during life history transitions in Laysan Albatross (Phoebastria immutabilis)
