El mercado de acciones colombiano ha crecido notablemente en décadas recientes, aunque sigue siendo ilíquido y concentrado. Esta situación no parece responder a determinantes macroeconómicos externos, ni en gran medida a ...
Increases of kinin B-1 and B-2 receptors binding sites after brain infusion of amyloid-beta 1-40 peptide in rats
(Elsevier B.V., 2008-12-01)
Although numerous inflammation pathways have been implicated in Alzheimer's disease, the involvement of the kallikrein-kinin system is still under investigation. We anatomically localized and quantified the density of kinin ...

Effect of intermittent hypoxia on cardiovascular function, adrenoceptors and muscarinic receptors in wistar rats
(CAMBRIDGE UNIV PRESS, 2002)
The usual model of intermittent hypoxia (sleep apnoea) corresponds to repeated episodes of hypoxia from a few seconds to a few hours interspersed with episodes of normoxia. The aim of this study was to evaluate in rats the ...
Demonstration of specific high affinity receptors for aldosterone in cytosol of rat colon
(1986)
Since both aldosterone and glucocorticoids increase cation transport in rat distal colon, and a specific glucocorticoid high affinity cytosolic receptor has been indentified in this tissue, it was possible that the action ...

Evidence for two progesterone receptor binding sites in murine mammary carcinomas
(Pergamon-Elsevier Science Ltd., 2003-01)
We have evaluated the progesterone receptor (PR) binding patterns in progestin-dependent and -independent murine mammary carcinomas; all variants regress completely after antiprogestin treatment. These studies revealed the ...
Paradoxical sleep deprivation increases plasma endothelin levels
(Associação Brasileira de Divulgação Científica, 2002-01-01)
The endothelins (ET-1, 2 and 3) constitute a family of 21 amino acid peptides with potent biological activities. ET-1 is one of the most potent endogenous vasoconstrictors so far identified and its increased concentration ...
