Non-homogeneous distribution of steroids in fecal pellets: An example in brown brocket deer (Mazama gouazoubira) with progesterone metabolites
(2019-10-01)
Measuring reproductive hormones in feces has become an important tool in the endocrine characterization of wild animals’ reproduction. However, several factors may influence its success, such as fecal collection and storage ...
Crossover of the hypothalamic pituitary–adrenal/interrenal, –thyroid, and –gonadal axes in testicular development
(Frontiers, 2014-08)
Besides the well-known function of thyroid hormones (THs) for regulating metabolism, ithas recently been discovered that THs are also involved in testicular development in mam-malian and non-mammalian species. THs, in ...
Interaction between thyroid hormones and gonadotropin inhibitory hormone in ex vivo culture of zebrafish testis: An approach to study multifactorial control of spermatogenesis
(2021-07-15)
Reproduction is under multifactorial control of neurohormones, pituitary gonadotropins, as well as of local gonadal signaling systems including sex steroids, growth factors and non-coding RNAs. Among the factors, ...

Endocrine response and ovum transport in women treated with D-Trp6-luteinizing hormone-releasing hormone in the postovulatory period
(1982)
Possible alterations in ovum transport during increased activity of the hypothalamic-pituitary-ovarian axis were investigated in women. D-Trp6-luteinizing hormone (LH)-releasing hormone, a synthetic peptide with potent ...
Seasonal changes in steroid and thyroid hormone content in shed skins of the tegu lizard Salvator merianae
(2022-01-01)
Sampling blood for endocrine analysis from some species may not be practical or ethical. Quantification of hormones extracted from nontypical sample types, such as keratinized tissues, offers a less invasive alternative ...
Circulating forms of parathyroid hormone detected with an immunofluorometric assay in patients with primary hyperparathyroidism and in hyperparathyroidism secondary to chronic renal failure
(Associação Brasileira de Divulgação Científica, 2001-12-01)
In patients with uremia, intact parathyroid hormone (PTH) measurement appears to overestimate the biologically active hormone in circulation. The recent description of the accumulation in these patients of a non-intact PTH ...
Effect of thyroid hormone administration on the depletion of circulating glutathione in the isolated perfused rat liver and its relationship to basolateral γ‐glutamyltransferase activity
(1995)
The influence of thyroid hormone administration on liver glutathione (GSH) extraction in the isolated perfused liver was studied in fed rats for a period of 1–7 days following a single dose of 0.1 mg 3,5,3′‐triiodothyronine ...
