The external genitalia in juvenile Caiman latirostris differ in hormone sex determinate-female from temperature sex determinate-female
(Academic Press Inc Elsevier Science, 2019-03)
The broad-snouted caiman (Caiman latirostris) is a crocodilian species that inhabits South American wetlands. As in all other crocodilians, the egg incubation temperature during a critical thermo-sensitive window (TSW) ...
Characterization of Gonadotropin-Releasing Hormone (GnRH) Genes From Cartilaginous Fish: Evolutionary Perspectives
(Frontiers Media S.A., 2018-09)
The neuropeptide gonadotropin-releasing hormone (GnRH) plays an important role in the control of reproductive functions. Vertebrates possess multiple GnRH forms that are classified into three main groups, namely GnRH1, ...
Differential regulation of ovarian anti-müllerian hormone (AMH) by estradiol through α- and β-estrogen receptors
(Endocrine Society, 2012-09)
Background: Anti-Müllerian hormone (AMH) is a member of the TGF-β family, which limits follicle maturation. Recently serum AMH has been recognized as a useful diagnostic and prognostic tool in human reproductive endocrinology. ...
The influence of sex steroid hormones in the immunopathology of experimental pulmonary tuberculosis
(Public Library of Science, 2014-04)
The relation between men and women suffering pulmonary tuberculosis is 7/3 in favor to males. Sex hormones could be a significant factor for this difference, considering that testosterone impairs macrophage activation and ...
Effects of 2,4-dichlorophenoxyacetic acid on the ventral prostate of rats during the peri-pubertal, pubertal and adult stage
(Taylor & Francis, 2016-10)
The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is used on a wide variety of terrestrial and aquatic broadleaf weeds. 2,4-D has been shown to produce a wide range of adverse effects on animal and human health. The aim ...
Ghrelin directly stimulates glucagon secretion from pancreatic α-cells
(Oxford University Press, 2011-09)
Previous work has demonstrated that the peptide hormone ghrelin raises blood glucose. Such has been attributed to ghrelin's ability to enhance GH secretion, restrict insulin release, and/or reduce insulin sensitivity. ...
Intérêt du dosage de l’hormone anti-müllérienne pour le diagnostic et la définition des anomalies de la différenciation sexuelleUsefulness of anti-mullerian determination in the diagnosis and definition of disorders of sex development
(John Libbey, 2014-03)
Le testicule fœtal sécrète deux hormones distinctes : la testostérone qui provoque la différenciation des canaux de Wolff et la masculinisation du sinus urogénital et des organes génitaux externes, et l’hormone anti-Müllérienne ...
Interaction of sex chromosome complement, gonadal hormones and neuronal steroid synthesis on the sexual differentiation of mammalian neurons
(Taylor & Francis Ltd, 2017-10-27)
Female mouse hippocampal and hypothalamic neurons growing in vitro show a faster development of neurites than male mouse neurons. This sex difference in neuritogenesis is determined by higher expression levels of the ...
Expression of gonadal hormone receptors in pars distalis and pars tuberalis of viscachas in relation to pregnancy
(Universidad Nacional de Cuyo, 2019)
In mammals, parsdistalis (PD) is the anterior pituitary region mainly involved in the regulation of metabolism, growth and reproduction. Pars tuberalis (PT) has long been thought to be a support for the PD, supplementing ...
Evaluation of ovarian response and oocyte quality in domestic cats treated with two administration schemes of follicle stimulating hormone (FSH)Evaluación de respuesta ovárica y calidad de ovocitos en gatas tratadas con hormona folículo estimulante (FSH) utilizando dos esquemas de administración
