Changes in plasma steroid hormones and gonadal histology associated with sexual maturation in wild southern hake (Merluccius australis)
(Pontificia Universidad Católica de Valparaíso, 2017)
Prenatal exposure to bisphenol A promotes angiogenesis and alters steroid-mediated responses in the mammary glands of cycling rats
(Pergamon-Elsevier Science Ltd, 2011-10)
Prenatal exposure to BPA disturbs mammary gland histoarchitecture and increases thecarcinogenic susceptibility to chemical challenges administered long after BPA exposure.Our aim was to assess the effect of prenatal BPA ...
Novel, low cost, highly effective, handmade steroid pellets for experimental studies
(Public Library Of Science, 2013-05-15)
The basic component of SilasticH glue (Dow Corning) used to prepare SilasticH pellets is polydimethylsiloxane. This compound is also present in other commercial adhesives such as FASTIXH (Akapol SA) that are available in ...
Influence of steroids on hydrogen bonds in membranes assessed by near infrared spectroscopy
(Elsevier Science, 2021-04-01)
The covalent O[sbnd]H bonds of water vibrate and absorb radiation in the near infrared (NIR) region at wavelengths that vary according to the strength of the bonds which, at the same time, are sensitive to the number and/or ...
Reproductive cycle of leopard grouper Mycteroperca rosacea (Streets, 1877) held in captivity: relationship between gonad development and sex steroid concentration
(Pontificia Universidad Católica de Valparaíso, 2018)
Salivary steroids in response to ACTH: a less invasive approach to assess adrenal function in hypotensive patients with chronic renal failure
(Lippincott Williams, 2006-01)
Summary OBJECTIVE Hypotension increases morbidity and mortality in patients with chronic renal failure .However, adrenocortical insufficiency has not been deeply investigated as possible physiopathologic mechanism of this ...
Effects of atrazine on vitellogenesis, steroid levels and lipid peroxidation, in female red swamp crayfish Procambarus clarkii
(Elsevier Science, 2018-04)
Atrazine, a widely use herbicide, has been classified as a potential endocrine disruptor, especially for freshwater species. In this study, we tested the hypothesis that atrazine can affect reproduction in crayfish through ...
Disruption in the expression and immunolocalisation of steroid receptors and steroidogenic enzymes in letrozole-induced polycystic ovaries in rat
(Csiro Publishing, 2009-12)
The objective of the present study was to characterise the expression and tissue distribution of steroid receptors (oestrogen receptor- and (ER, ER), androgen receptor (AR) and progesterone receptor (PR)) and steroidogenic ...
Oocyte maturation in the toad Rhinella arenarum (Amphibia, Anura): Evidence of cAMP involvement in steroid production and action
(Wiley-liss, Div John Wiley & Sons Inc, 2018-02)
In this work, we describe the participation of the adenylate cyclase/3′-5′-cyclic adenonsine monophosphate (cAMP) pathway in the seasonal follicular secretion of progesterone (P 4 ) and testosterone (T), and its relationship ...
