Efectos agudos de la restricción, choque y entrenamiento en el laberinto elevado en T en los sistemas de noradrenalina y serotonina en la corteza prefrontal.
(Universidad Católica de Colombia, 2014-07-01)
La corteza prefrontal (CPF) participa en las funciones cognitivas y la regulación del estrés. Las concentraciones de noradrenalina (NA) y serotonina (5-HT) en algunas regiones en el sistema nervioso central son modificadas ...
Seasonal changes in the activity of the adrenal medulla of viscacha (Lagostomus maximus maximus)
(Wiley, 2013-04)
Animals living in nontropical climates modify their physiology and behavior to adapt to seasonal environmental changes. Part of this adaptation involves the release of catecholamine from sympathetic nerve endings and the ...
Evidence of a role for melatonin in fetal sheep physiology: direct actions of melatonin on fetal cerebral artery, brown adipose tissue and adrenal gland
(BLACKWELL PUBLISHING, 2008-08-15)
Although the fetal pineal gland does not secrete melatonin, the fetus is exposed to melatonin of
maternal origin. In the non-human primate fetus, melatonin acts as a trophic hormone for the
adrenal gland, stimulating ...
Locus coeruleus mediates cold stress-induced polycystic ovary in rats
(ENDOCRINE SOC, 2008)
Previous reports about the rat ovary have shown that cold stress promotes ovarian morphological alterations related to a polycystic ovary (PCO) condition through activation of the ovarian sympathetic nerves. Because the ...
Obesity induced by neonatal treatment with monosodium glutamate impairs microvascular reactivity in adult rats: Role of NO and prostanoids
(ELSEVIER SCI LTD, 2011)
Background and aim: given that obesity is an independent risk factor for the development of cardiovascular diseases we decided to investigate the mechanisms involved in microvascular dysfunction using a monosodium glutamate ...
Adrenoceptors: non conventional target for breast cancer?
(Bentham Science Publishers, 2009-05)
Epinephrine and Norepinephrine, typically released during stress bind to nine different adrenoceptors (AR) which classically control the cardiovascular and respiratory systems. New targets were described for the many ...
Acute stress or systemic insulin injection increases flunitrazepam sensitive-GABAA receptor density in synaptosomes of chick forebrain: Modulation by systemic epinephrine
(Taylor & Francis Ltd, 2009-06-07)
Interactions between acute stress and systemic insulin and epinephrine on GABAA receptor density in the forebrain were studied. Here, 10 day-old chicks were intraperitoneally injected with insulin, epinephrine or vehicle ...
