Corticosterone in Lymphoma-Bearing Rats.

Experimental Biology and Medicine, 1963
SummaryCorticosterone in plasma and urine was determined by spectrofluorometry in sulfuric acid and by direct spectrophotometry in ethanol. Plasma levels and urinary excretion of corticosterone were elevated in rats with subcutaneous lymphomas. The high plasma concentration of corticosterone in these rats may help to explain the reduction in splenic ...

Transcriptional Activation of Elephant Shark Mineralocorticoid Receptor by Corticosteroids, Progesterone and Spironolactone [PDF]

arXiv, 2018
We report the analysis of activation by corticosteroids and progesterone of full-length mineralocorticoid receptor (MR) from elephant shark, a cartilaginous fish belonging to the oldest group of jawed vertebrates. Based on their measured activities, aldosterone, cortisol, 11-deoxycorticosterone, corticosterone, 11-deoxcortisol, progesterone and 19 ...

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

N-terminal domain Increases Activation of Elephant Shark Glucocorticoid and Mineralocorticoid Receptors [PDF]

arXiv, 2019
Cortisol, corticosterone and aldosterone activate full-length glucocorticoid receptor (GR) from elephant shark, a cartilaginous fish belonging to the oldest group of jawed vertebrates. Activation by aldosterone a mineralocorticoid, indicates partial divergence of elephant shark GR from the MR.

Early positive tactile stimulation reverses the increase of anxiety and decrease of sociality induced by early chronic mechanical pain in mandarin voles

Integrative Zoology, EarlyView.
This study used a tail‐pinching model during development to simulate mechanical pain experienced by pups in high‐social mandarin voles (Microtus mandarinus). Subsequently, brush‐like positive tactile stimuli were applied to the backs of the mandarin voles.

Bluer in the city: urban male lizards exhibit more intense sexual coloration and lower parasite loads than non‐urban males

Integrative Zoology, EarlyView.
The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

Source population and time spent in captivity affect survival and reproduction of long‐distance translocated northern bobwhites

Animal Conservation, EarlyView.
Long‐distance translocations of northern bobwhites are increasingly used to access source populations with sufficient densities for translocation. This study compared the survival and productivity of bobwhites translocated from the South Texas Plains and the Floridian Coastal Plain to the Floridian Coastal Plain, revealing higher survival and fecundity

Corticosterone enhances the potency of ethanol against hippocampal long-term potentiation via local neurosteroid synthesis

Frontiers in Cellular Neuroscience, 2015
Corticosterone is known to accumulate in brain after various stressors including alcohol intoxication. Just as severe alcohol intoxication is typically required to impair memory formation only high concentrations of ethanol (60mM) acutely inhibit long ...

Non-breeding feather concentrations of testosterone, corticosterone and cortisol are associated with subsequent survival in wild house sparrows

Proceedings of the Royal Society B: Biological Sciences, 2012
Potential mechanistic mediators of Darwinian fitness, such as stress hormones or sex hormones, have been the focus of many studies. An inverse relationship between fitness and stress or sex hormone concentrations has been widely assumed, although ...
