Evaluación del efecto de tres polimorfismos en el gen del receptor adrenérgico beta-2 en el trabajo de parto pretérmino
(Universidad de Antioquia, Facultad de MedicinaMedellín, Colombia, 2022)
Interacción entre los polimorfismos del receptor ß1 y ß2 adrenérgico como predictor de riesgo de insuficiencia cardiaca crónica
(SOC MEDICA SANTIAGO, 2008-11)
Background: beta adrenergic receptors (AR) are highly polymorphic and important regulators of cardiovascular homeostatis. Among these, beta(1) and beta(2) AR regulate cardiac contractility and frequency and are important ...
Cardiac fibroblasts as sentinel cells in cardiac tissue: Receptors, signaling pathways and cellular functions
(Elsevier, 2015)
Cardiac fibroblasts (CF) not only modulate extracellular matrix (ECM) proteins homeostasis, but also respond to chemical and mechanical signals. CF express a variety of receptors through which they modulate the proliferation/cell ...
Effects of adrenalectomy on the stress-induced changes in ovarian sympathetic tone in the rat
(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 ...
Testosterone induces an intracellular calcium increase by a nongenomic mechanism in cultured rat cardiac myocytes
(ENDOCRINE SOC, 2006-03)
Androgens are associated with important effects on the heart, such as hypertrophy or apoptosis. These responses involve the intracellular androgen receptor. However, the mechanisms of how androgens activate several membrane ...
Catechol-mediated effects of harmaline on the action potential of rat atrial fibres
(Oxford University Press, 1977)
Summary: The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the ...
Catechol mediated effects of harmaline on the action potential of rat atrial fibres
(1977)
The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the slow ...
