The authors investigated a large number of stressors and measures of psychological distress in a multicenter, prospective cohort study of spontaneous preterm birth among 5,337 Montreal (Canada)-area women who delivered from October 1999 to April 2004. In addition, a nested case-control analysis (207 cases, 444 controls) was used to explore potential biologic pathways by analyzing maternal plasm...
Maternal deprivation (MD) is frequently used as an early life stress model in rodents to investigate behavioral and neurological responses under stressful conditions. However, the effect of MD on the early postnatal development of rodents, which is when multiple neural systems become established, is rarely investigated due to methodological limitations. Ultrasonic vocalizations (USVs) are one o...
AIM The aim of this study was to compare the level of stress in mothers of school-aged children born late preterm and admitted to the intensive care unit (ICU) with the level of maternal stress if a child was born late preterm and not admitted to the ICU as well as if a full-term child was admitted to the ICU. METHODS In this retrospective cohort study the data were gathered via telephone int...
Introduction Maternal separation is an early life stress event associated with behavioral alterations and ethanol consumption. We aimed to expand the current understanding on the molecular mechanisms mediating the impact of postnatal stress on ethanol consumption. Methods In the first experiment (T1), some of the pups were separated from their mothers for 6 hr daily (Maternal Separation group...
Preexisting maternal diabetes increases the risk of neural tube defects (NTDs). The mechanism underlying maternal diabetes-induced NTDs is not totally defined, and its prevention remains a challenge. Autophagy, an intracellular process to degrade dysfunction protein and damaged cellular organelles, regulates cell proliferation, differentiation, and apoptosis. Because autophagy impairment causes...
Recent research conducted with nonhuman primates confirms that adaptive emotional processes, such as maternal attraction arousability and maternal anxiety arousability, enhance and sustain female motivation to interact with infants, invest in them, and protect them during the postpartum period. Changes in these emotional processes, and concomitant changes in maternal motivation, facilitate the ...
UNLABELLED Maternal distress during pregnancy increases plasma levels of cortisol and corticotrophin releasing hormone in the mother and foetus. These may contribute to insulin resistance and behaviour disorders in their offspring that include attention and learning deficits, generalized anxiety and depression. The changes in behaviour, with or independent of alterations in the function of the ...
The present study analyzes the interaction between prenatal stress and mother's behavior on brain, hormonal, and behavioral development of male offspring in rats. It extends to males our previous findings, in females, that maternal care can alter behavioral dimorphism that becomes evident in the neonates when they mature. Experiment 1 compares the maternal behavior of foster mothers toward cros...
ment can have a powerful influence on stress levels of the offspring later in life as a result of lasting epigenetic modifications. According to work published in The Joural of Neuroscience, it now seems that just as gene expression can be altered during development, it can also be altered later in life to reverse these modifications. Stress responses are mediated by regulation of the hypothala...
