    • Circadian clocks during embryonic and fetal development 
      Serón Ferré, María; Valenzuela, Gullermo J.; Torres Farfán, Claudia (2007)
      Circadian rhythmicity is a fundamental characteristic of organisms, which helps ensure that vital functions occur in an appropriate and precise temporal sequence and in accordance with cyclic environmental changes. Living ...
    • Deciphering the function of the blunt circadian rhythm of melatonin in the newborn lamb: impact on adrenal ... 
      Serón Ferré, María; Torres Farfán, Claudia; Valenzuela, Francisco J.; Castillo Galán, Sebastián; Rojas, Auristela; Mendez, Natalia; Reynolds, Henry; Valenzuela, Guillermo; Llanos Mansilla, Jorge (Oxford University Press, 2017)
      Neonatal lambs, as with human and other neonates, have low arrhythmic endogenous levels of melatonin for several weeks until they start their own pineal rhythm of melatonin production at approximately 2 weeks of life. ...
    • 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 ...
    • Evidence of a role for melatonin in fetal sheep physiology: direct actions of melatonin on fetal cerebral ... 
      Torres Farfán, Claudia; Valenzuela, Francisco J.; Mondaca, Mauricio; Valenzuela, Guillermo J.; Krause, Bernardo; Herrera Videla, Emilio; Riquelme González, Raquel; Llanos Mansilla, Jorge; Serón Ferré, María (BLACKWELL PUBLISHING, 2008-08-15)
      Although the fetal pineal gland does not secrete melatonin, the fetus is exposed to melatonin of maternal origin. In the non-human primate fetus, melatonin acts as a trophic hormone for the adrenal gland, stimulating ...
    • Gestational chronodisruption leads to persistent changes in the rat fetal and adult adrenal clock and function 
      Salazar, E. R.; Richter, H. G.; Spichiger, C.; Mendez, N.; Halabi, D.; Vergara, K.; Alonso, I. P.; Corvalán, F. A.; Azpeleta, C.; Serón Ferré, María; Torres Farfán, Claudia (Blackwell Publishing Ltd, 2018)
      © 2018 The Authors. The Journal of Physiology © 2018 The Physiological Society Key points: Light at night is essential to a 24/7 society, but it has negative consequences on health. Basically, light at night induces an ...
    • Impact of maternal melatonin suppression on amount and functionality of brown adipose tissue (BAT) in the ... 
      Serón Ferré, María; Reynolds, H.; Mendez, N.; Mondaca, M.; Valenzuela, F. J.; Ebensperger, R.; Valenzuela, G. J.; Herrera, E. A.; Llanos Mansilla, Jorge; Torres Farfán, Claudia (Frontiers Media S.A., 2014)
      © 2014 Seron-ferre, Reynolds, Mendez, Mondaca, Ebensperger, Valenzuela, Valenzuela, Herrera, Llanos and Torres-farfan. In human and sheep newborns, brown adipose tissue (BAT) accrued during fetal development is used for ...
    • Melatonin relations with respiratory quotient weaken on acute exposure to high altitude 
      Tapia, Marcelo; Wulff-Zottele, Cristian; De Gregorio, Nicole; Lang, Morin; Varela, Héctor; Serón Ferré, María; Vivaldi Véjar, Ennio; Araneda, Oscar; Silva Urra, Juan; Gunga, Hanns-Christian; Behn Thiele, Claus (Frontiers Media, 2018-06-29)
      High altitude (HA) exposure may affect human health and performance by involving the body timing system. Daily variations of melatonin may disrupt by HA exposure, thereby possibly affecting its relations with a metabolic ...
    • Potential adverse effects of antenatal melatonin as a treatment for intrauterine growth restriction: findings ... 
      González Candia, Alejandro; Véliz, Marcelino; Araya, Claudio; Quezada, Sebastián; Ebensperger Darrouy, Germán; Serón Ferré, María; Reyes, Roberto V.; Llanos Mansilla, Jorge; Herrera Videla, Emilio (Mosby-Elsevier, 2016)
      BACKGROUND: Intrauterine growth restriction is a condition in which the fetus has a birthweight and/or length <10th percentile for the gestational age. Intrauterine growth restriction can be associated with various causes, ...
    • 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 ...
