Oxidative stress and altered steroidogenesis in the ovary by cholinergic stimulation of coeliac ganglion in the first proestrous in rats. Implication of nitric oxide
(Academic Press Inc Elsevier Science, 2016-02-29)
An ex-vivo Coeliac Ganglion-Superior Ovarian Nerve-Ovary (CG-SON-O) system from virgin rats in the first proestrous was used to test whether cholinergic stimulation of CG affects oxidative status and steroidogenesis in the ...
Participation of the extrinsic cholinergic innervation in the action of nitric oxide on the ovarian steroidogenesis in the first proestrous in rats
(Academic Press Inc Elsevier Science, 2016-09)
An ex-vivo Coeliac Ganglion-Superior Ovarian Nerve-Ovary (CG-SON-O) system and an ovary without peripheral neural influence from virgin rats in the first proestrous were used to test whether ovarian extrinsic innervation ...
The production of nitric oxide in the coeliac ganglion modulates the effect of cholinergic neurotransmission on the rat ovary during the preovulatory period
(Academic Press Inc Elsevier Science, 2018-05)
The aim of the present work was to investigate whether the nitric oxide produced by the nitric oxide/nitric oxide synthase (NO/NOS) system present in the coeliac ganglion modulates the effects of cholinergic innervation ...
Both orexin receptors are expressed in rat ovaries and fluctuate with the estrous cycle. Effects of orexin receptor antagonists on gonadotropins and ovulation
(American Physiological Society, 2007-10)
Orexins are peptides controlling feeding, sleep, and neuroendocrine functions. They are synthesized by the hypothalamus with projections throughout the brain. Orexins and their orexin 1 (OX(1)) and orexin 2 receptors (OX(2)) ...
Alterações na evocação de uma memória aversiva ao liongo do ciclo estral de ratas: influências da transmissão gabaérgica na amígdala
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em PsicobiologiaEstudos de Comportamento; Psicologia Fisiológica, 2012-07-30)
GABAergic neurotransmission has been implicated in many aspects of
learning and memory, as well as mood and anxiety disorders. The amygdala
has been one of the major focuses in this area, given its essential role in
modulating ...
Ovaric physiology in the first oestral cycle: Influence of noradrenergic and cholinergic neural stimuli from coeliac ganglion
(Elsevier Science Inc, 2010-10)
Both peripheral innervation and nitric oxide (NO) participate in ovarian steroidogenesis. The aims of the work were (1) to investigate whether ganglionic noradrenergic (NE) and cholinergic (Ach) stimulus modify the ovarian ...
Effects of melatonin on ovarian follicles
(Excerpta MedicaAmsterdam, 2013-02)
Objective: To evaluate the histomorphometry and expression of Ki-67 and c-kit in ovarian follicles of pinealectomized or melatonin-treated pinealectomized rats. Study design: Forty adult rats were randomly divided into ...

Objective: To evaluate the histomorphometry and expression of Ki-67 and c-kit in ovarian follicles of pinealectomized or melatonin-treated pinealectomized rats.Study design: Forty adult rats were randomly divided into four ...
Reproductive Parameters of the Dogo Argentino Bitch
(Hindawi Publishing Corporation, 2013-09)
The Dogo Argentino (DA) is the first and only breed from Argentina recognized worldwide. Although its morphologic features have been well established, its normal reproductive parameters are not clearly known. The aim of ...
Multiple failures in the lutenising hormone surge generating system in GABAB1KO female mice
(Wiley Blackwell Publishing, Inc, 2019-09)
Female mice lacking GABAB receptors, GABAB1KO, show disrupted oestrous cycles, reduced pregnancies and increased hypothalamic Gnrh1 mRNA expression, whereas anteroventral periventricular/periventricular preoptic nucleus ...
