Ronco Macchiavello, Ana María; Llaguno, Emanuel; Epuñán, María José; Llanos Silva, Miguel (PERGAMON-ELSEVIER SCIENCE LTD, 2010-09)Cadmium is a toxicant with known carcinogenic and endocrine disruptor effects. We have previously reported that prenatal exposure to cadmium may induce low birth weight which is associated to increased foetal exposure ...

Aguirre, C. A.; Castillo, V. A.; Llanos Silva, Miguel (Nature Publishing, 2015)Type 1 cannabinoid receptors (CB1R) modulate energy balance; thus, their premature activation may result in altered physiology of tissues involved in such a function. Activation of CB1R mainly occurs after binding to the ...

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, ...

Torres Morales, Patricio; Socias, Teresa; Cortez, Jacqueline; Llanos Silva, Miguel (1994)The effect of chymotrypsin inhibitors and substrates on the human sperm acrosome reaction stimulated by the human zonae pellucidae or follicular fluid were evaluated. Motile spermatozoa, selected by a Percoll gradient, ...

Peñailillo, Reyna; Guajardo, Angélica; Llanos Silva, Miguel; Hirsch Birn, Sandra; Ronco Macchiavello, Ana María (Public Library Science, 2015)In the placenta, 11 beta-hydroxysteroid dehydrogenase type 2 (11 beta-HSD2) limits fetal glucocorticoid exposure and its inhibition has been associated to low birth weight. Its expression, encoded by the HSD11B2 gene is ...

Rodriguez, Juan; Monsalves Álvarez, Matías; Henriquez, Sandra; Llanos Silva, Miguel; Troncoso Cotal, Rodrigo (Elsevier Science, 2016-11)Glucocorticoids are involved in several responses triggered by a variety of environmental and physiological stimuli. These hormones have a wide-range of regulatory effects in organisms. Synthetic glucocorticoids are ...
