Reproductive and immune effects of chronic corticosterone treatment in male White's treefrogs, Litoria caerulea
Kristine Kaiser,Julia Devito,Caitlin G. Jones,Adam Marentes,Rachel Perez,Lisa Umeh,Regina M. Weickum,Kathryn E. McGovern,Emma H. Wilson,Wendy Saltzman +9 more
TL;DR: It is suggested that corticosterone inhibits immune but not reproductive function in this species in response to chronic stress.

Does physiological response to disease incur cost to reproductive ecology in a sexually dichromatic amphibian species
TL;DR: Field data provides novel evidence that increased physiological stress response associated with Bd infection in wild frogs, could suppress reproduction by down-regulating gonadal hormones in amphibians, however the impacts on reproductive output is yet to be established.

Calling rate, corticosterone plasma levels and immunocompetence of Hypsiboas albopunctatus
Stefanny Christie Monteiro Titon,Vania Regina Assis,Braz Titon,Adriana Maria Giorgi Barsotti,Sarah P. Flanagan,Fernando Ribeiro Gomes +5 more
TL;DR: Investigating the relationship between calling rate, immunocompetence, and CORT in Hypsiboas albopunctatus, a midsize anuran occurring in South America concluded that calling activity shows a cost in terms of cellular immune response, but this compromise does not appear to be mediated by glucocorticoid plasma levels.
Book ChapterDOI
Physiological ecology and conservation of anuran amphibians
TL;DR: In this paper, the authors discuss the potential of physiological ecology to enhance our understanding of such complex problems and highlight the aspects of amphibian physiological ecology that are consequential in the context of responses to climate change.

Does physiological response to disease incur cost to reproductive ecology in a sexually dichromatic amphibian species? Part A Molecular & integrative physiology
TL;DR: In this paper, the authors investigated the impact of chytridiomycosis on amphibian reproduction and found that increased physiological stress response associated with Bd infection in wild frogs, could suppress reproduction by down-regulating gonadal hormones in amphibians.

Direct inhibitory effect of glucocorticoids upon testicular luteinizing hormone receptor and steroidogenesis in vivo and in vitro.
TL;DR: The direct inhibitory effect of glucocorticoids on testicular LH receptor content and steroidogenesis is demonstrated, suggesting the adrenal glucocORTicoids may regulate testis functions.

Purification of a 17β-Hydroxysteroid Dehydrogenase of Human Placenta and Studies on Its Transhydrogenase Function
TL;DR: Methods for the extensive purification of a soluble 17@-hydroxysteroid dehydrogenasel of human placenta are described, which appears to be responsible for the entire 17/3estradiol-mediated transfer of hydrogen between pyridine nucleotides in soluble extracts of this tissue.

Glucocorticoid-Mediated Repression of P450scc mRNA and de Novo Synthesis in Cultured Leydig Cells
Dale B. Hales,Anita H. Payne +1 more
TL;DR: The finding on the negative regulation of P450(17 alpha) protein synthesis by testosterone suggest that the steroidogenic P450 enzymes in Leydig cells are negatively regulated by steroid hormones acting via their cognate receptors.
