(Endocrine Society, 1996)Several members of the neurotrophin (NT) family, including nerve growth factor (NGF), NT-3, and NT-4/5, are expressed in the mammalian ovary. As their respective receptor tyrosine kinases are also found in the gland, the ...
-
(1993)Polycystic ovarian syndrome (PCOS) is one of the most common human ovarian pathologies affecting women of reproductive age. Despite extensive investigation, the etiology of PCOS remains poorly understood. Experimentally, ...
-
(2006)Background: Corticosterone reduction produced by adrenalectomy (ADX) induces apoptosis in dentate gyrus (DG) of the hippocampus, an effect related to an increase in the expression of the pro-apoptotic gene bax. However it ...
-
(ELSEVIER SCIENCE BV, 2011-01)Autophagy is a physiological degradative process key to cell survival during nutrient deprivation, cell differentiation and development. It plays a major role in the turnover of damaged macromolecules and organelles, and ...
-
(Universidad de ChileCyberDocs, 2011)El estrés es la forma que posee el organismo para afrontar una situación agobiante y/o amenazadora. Frente a una situación de estrés, el organismo responde activando el Sistema Nervioso Simpático, lo que produce un aumento ...
-
(ENDOCRINE SOC, 2008-10)Catecholamines present in the mammalian ovary are involved in many normal aspects of ovarian functions, including initial follicle growth, steroidogenesis, and pathological states such as polycystic ovary syndrome. Sympathetic ...
-
(Sociedad Española de Endocrinología y Nutrición, 2004)El estrés, como un mecanismo general de respuesta simpática exagerada, involucra grandes cambios en la homeostasis del organismo. No existen dudas acerca de las alteraciones que provoca el estrés, tanto en el comportamiento ...
-
(WILEY-LISS, INC., 2002)Although it has been known for many years that the ovary is innervated by catecholaminergic nerve fibers and much experimental evidence has strengthened the notion that catecholamines are physiologically involved in the ...
-
(SOC STUDY REPRODUCTION, 2003-06)We studied the effects of a chronic intermittent cold stress regime on sympathetic nerve activation and ovarian physiology. This paradigm (4degreesC for 3 h/day, Monday-Friday, for 3 or 4 wk) does not affect basal plasma ...
-
(2010)We previously reported that centrally-induced sympathetic activation in response to cold stress is associated with a polycystic ovarian condition in rats, and thyrotrophin-releasing hormone (TRH) released locally from the ...
-
(Universidad de Chile, 2013)El síndrome del ovario poliquístico (SOP), es la patología endocrina más común que afecta las mujeres durante su etapa reproductiva, se presenta en una variedad de fenotipos heterogéneos que van desde una condición de ...
-
Developmental and Functional Effects of Steroid Hormones on the Neuroendocrine Axis and Spinal Cord (Wiley, 2016)This review highlights the principal effects of steroid hormones at central and peripheral levels in the neuroendocrine axis. The data discussed highlight the principal role of oestrogens and testosterone in hormonal ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2003-02-01)The contribution of distinct Ca2+-sensitive protein kinases to the regulation of the expression of the synaptosomal-associated protein SNAP-25 was examined in bovine chromaffin cells. Prolonged incubation with high K+ (38 ...
-
(Universidad de Chile, 2011)La función ovárica es controlada por un eje endocrino y una regulación nerviosa paralela. La administración de valerato de estradiol (EV) a ratas produce una condición morfológica de ovario poliquístico (PCO) que ...
-
Efecto de la hormona liberadora de tirotrofina (TRH) en la secreción de prolactina de decidua humana (Sociedad Chjilena de Obstetricia y Ginecología, 2000)Para prevenir el Síndrome de Distress Respiratorio (RDS), se ha usado el tratamiento conjunto de betametasona y hormona liberadora de tirotrofina (TRH). La TRH actuaría indirectamente sobre la producción del surfactante ...
-
(Universidad de ChilePrograma Cybertesis, 2007)La depresión mayor es uno de los desórdenes del ánimo más comunes. Aunque no se conoce la etiología de la depresión, se ha establecido que esta condición podría producirse como consecuencia de la interacción de los genes ...
-
(Universidad de ChilePrograma Cybertesis, 2008)El estrés reconocido como un desequilibrio provocado por un estímulo, tiene múltiples efectos sobre los organismos vivos y además en órganos específicos. Nuestro laboratorio ha encontrado que el estrés por frío activa ...
-
(Frontiers Media S.A., 2019)Sympathetic innervation of the ovary in rodents occurs via two routes: the superior ovarian nerve (SON), which runs along the ovarian ligament, and the plexus nerve (PN), which is mainly associated with the vasculature. ...
-
(HUMANA PRESS INC, 1999-04)A 3-wk period of stress promotes the development of ovarian cysts in rats apparently mediated by increased sympathetic nerve activity and ovarian steroid secretion. After 11 wk of stress, these parameters are indistinguishable ...
-
(2006)Background: Angiogenesis is a crucial process in follicular development and luteogenesis. The nerve growth factor (NGF) promotes angiogenesis in various tissues. An impaired production of this neurotrophin has been associated ...
