Forage fish to growing chicks: shared food resources between two closely related tern species
(Springer, 2019-09)
The assessment of the relevance of forage fsh in seabird diet and how diferent species partition food resources is fundamental to understand predator–prey relationships. We assessed the importance of forage fsh in the diet ...
Orexin A and B in vitro modify orexins receptors expression and Gonadotropins secretion of anterior pituitary cells of proestrous rats
(Elsevier Science, 2014-01)
Orexin A and orexin B (hypocretins) are neuropeptidessynthesized mainly by neurons located in the lateral hypothalamus andprojections throughout the brain. They are agonists at both the orexin 1and orexin 2 G protein-coupled ...
Desarrollo de un nanosistema para la entrega selectiva de microRNAs hacia células de cáncer ovárico
(Universidad de Chile, 2021)
El cáncer ovárico (CO) es la patología ginecológica más letal en las mujeres. Está ligada a un bajo pronóstico de vida dado el alto porcentaje de diagnósticos tardíos. Se caracteriza por presentar tumores voluminosos, ...
Interviene la galanina en la supresión de la síntesis y secreción de hormona luteinizante en la rata lactante
(1999)
Lo síntesis y secreción de LH está suprimida, pero no así la de FSH, en la pituitaria
de la rata lactante. Los factores que intervienen en esta inhibición selectiva se
conocen sólo parcialmente. Esta supresión podría deberse ...
Molecular mechanisms underlying AMH elevation in hyperoestrogenic states in males
(Nature, 2020-09-15)
Anti-Müllerian hormone (AMH) is secreted by Sertoli cells of the testes from early fetal life until puberty, when it is downregulated by androgens. In conditions like complete androgen insensitivity syndrome (CAIS), AMH ...
Oestradiol Induced Inhibition of Neuroendocrine Marker Expression in Leydig Cells of Adult Rats
(Wiley Blackwell Publishing, Inc, 2006-06)
The objectives of this work were to determine the changes in the expression of neuroendocrine markers in Leydig cell by estradiol treatment, and to determine whether testosterone is able to recover partially the effects ...

Proponemos la evaluación del poder predictivode parámetros clínicos y bioquímicos de pacientes,azoospérmicos como predictores del hallazgo de espermatozoidesen una biopsia testicular. Asimismoanalizaremos si en esas biopsias ...
Mechanisms of multiple forms of tumorigenesis in LH/hCG overexpressing transgenic mice
(Narosa Publishing, 2009)
The two gonadotrophins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland as heterodimers composed of a common a-subunit and the hormone- specific b-subunit. They have a ...
Characterization and seasonal changes in LHβ and FSHβ mRNA of Rhinella arenarum (Amphibia, Anura)
(Academic Press Inc Elsevier Science, 2013-06)
In anurans, two types of gonadotropins were described in several species of Ranidae and Pipidae families but only in one of the Bufonidae family. Rhinella arenarum is a bufonid that have the lowest concentration of plasma ...
