Ronco Macchiavello, Ana María; Llanos Silva, Miguel; Tamayo, Daniela; Hirsch Birn, Sandra (2007)The endogenous cannabinoid receptor agonist anandamide (AEA) exerts vascular effects such as vasodilatation and hypotension. In this study, we determined the effect of AEA on endothelin-1 production by cultured human ...

Ronco Macchiavello, Ana María; Tijmes, Matías; Santibáñez, Juan Fco.; Moraga, Paulina (1998)Human chorionic gonadotropin is a glycoprotein hormone that, like LH, stimulates steroidogenesis in gonadal cells. Using a desialylation process, 95 per cent of the sialic acid residues from an intact standard hCG molecule ...

Piñuñuri Flores, Raúl; Castaño Moreno, Erika; Llanos Silva, Miguel; Ronco Macchiavello, Ana María (Elsevier, 2020)Introduction: Folates are essential nutrients for fetal development and pregnancy outcomes; they are transported to the fetus during gestation through specific folate transporters located in the placenta. In preterm newborns, ...
-
Llanos Silva, Miguel; Ronco Macchiavello, Ana María (2009)The objectives of this study were: to measure some essential metals and toxicants in placentas of mothers delivering neonates with fetal growth restriction, and to establish potential associations between environmental ...

Sánchez, Hugo; Hossain, Mohammad B.; Lera Marques, Lydia; Hirsch Birn, Sandra; Albala Brevis, Cecilia; Uauy Dagach-Imbarack, Ricardo; Broberg, Karin; Ronco Macchiavello, Ana María (BIOMED Central Ltd., 2017)Background: Changes in DNA methylation, one of the most studied epigenetic mechanisms, are considered an initial marker for early cancer detection. We evaluated how availability of dietary factors (folates and vitamin B12) ...
-
Ronco Macchiavello, Ana María; Llanos Silva, Miguel; Valladares Boasi, Luis (1993)The effect of human chorionic gonadotropin (hCG) on intact Leydig cell phospholipid methylation was studied. Hormonal stimulation of rat Leydig cells increased the incorporation of[methyl-3H]methionine into phospholipids ...

The aim of this study was to evaluate the effect of oxidative stress on endothelial function in young and ...
-
Castillo, Paula; Ibáñez, Freddy; Guajardo, Angélica; Llanos Silva, Miguel; Ronco Macchiavello, Ana María (2012)Adverse fetal environment due to maternal undernutrition or exposure to environmental chemicals alters glucocorticoid (GC) metabolism increasing the risk of metabolic disorders in adulthood. In this study, we investigated ...
