    • Circadian rhythms in the fetus 
      Serón Ferré, María; Méndez, Natalia; Abarzúa Catalán, Lorena; Vilches, Nelson; Valenzuela, Francisco J.; Reynolds, Henry E.; Llanos Mansilla, Jorge; Rojas, Auristela; Valenzuela, Guillermo J.; Torres Farfán, Claudia (Elsevier, 2012)
      Throughout gestation, the close relationship between mothers and their progeny ensures adequate development and a successful transition to postnatal life. By living inside the maternal compartment, the fetus is inevitably ...
    • Developmental Programming of Capuchin Monkey Adrenal Dysfunction by Gestational Chronodisruption 
      Richter, Hans G.; Mendez, Natalia; Abarzúa Catalán, Lorena; Valenzuela, Guillermo J.; Serón Ferré, María; Torres Farfán, Claudia (Hindawi Limited, 2018)
      © 2018 Hans G. Richter et al. In the capuchin monkey (Cebus apella), a new-world nonhuman primate, maternal exposure to constant light during last third of gestation induces precocious maturation of the fetal adrenal and ...
    • Diurnal changes in light intensity inside the pregnant uterus in sheep 
      Parraguez Gamboa, Víctor; Sales, Francisco; Valenzuela, Guillermo J.; Vergara, Marcela; Catalán, Luis; Serón Ferré, María (1998)
      Penetration of light into the pregnant sheep uterus was studied in 9 ewes, gestational ages 40 to 142 days (term 147 days). Light Sensors were placed inside the pregnant horn and over the flank skin overlying the position ...
    • Effect of constant light on fetal and maternal prolactin rhythms in sheep 
      Parraguez Gamboa, Víctor; Valenzuela, Guillermo J.; Vergara, Marcela; Ducsay, Charles A.; Yellon, Steven M.; Serón Ferré, María (Endocrine Society, 1996)
      A 24-h rhythm of plasma PRL is present in fetal sheep. This rhythm is synchronized to an environmental clue (zeitgeber). We determined whether the light-dark cycle (L:D) is a zeitgeber for the fetal PRL rhythm and, if ...
    • Impact of Chronodisruption during Primate Pregnancy on the Maternal and Newborn Temperature Rhythms 
      Serón Ferré, María; Forcelledo, María Luisa; Torres Farfán, Claudia; Valenzuela, Francisco J.; Rojas, Auristela; Vergara, Marcela; Rojas García, Pedro; Recabarren, Mónica P.; Valenzuela, Guillermo J. (PLoS ONE, 2013)
      Disruption of the maternal environment during pregnancy is a key contributor to offspring diseases that develop in adult life. To explore the impact of chronodisruption during pregnancy in primates, we exposed pregnant ...
    • Mt1 melatonin receptor in the primate adrenal gland: Inhibition of adrenocorticotropin-stimulated cortisol ... 
      Torres Farfán, Claudia; Richter, Hans G.; Rojas García, Pedro; Vergara, Marcela; Forcelledo, María Luisa; Valladares Boasi, Luis; Torrealba, Fernando; Valenzuela, Guillermo J.; Serón Ferré, María (2003)
      The pineal hormone melatonin participates in circadian, seasonal, and reproductive physiology. The presence of melatonin binding sites in human brain and peripheral tissues is well documented. However, in the mammalian ...
    • Timed maternal melatonin treatment reverses circadian disruption of the fetal adrenal clock imposed by ... 
      Méndez, Natalia; Abarzúa Catalán, Lorena; Vilches, Nelson; Galdames, Hugo A.; Spichiger, Carlos; Richter, Hans G.; Valenzuela, Guillermo J.; Serón Ferré, María; Torres Farfán, Claudia (2012)
      Surprisingly, in our modern 24/7 society, there is scant information on the impact of developmental chronodisruption like the one experienced by shift worker pregnant women on fetal and postnatal physiology. There are ...
