Maternal sleep deprivation (MSD) has been suggested to be associated with increased frequency of neurodevelopmental disorders in offspring in both humans and animal models. However, the underlying cellular and molecular mechanism is still unclear. We have recently reported that MSD at different stages of pregnancy impairs the emotional and cognitive functions, and suppresses hippocampal CA1 long-term potentiation (LTP) in the offspring rats. Here, we report that the MSD induced LTP impairment at the CA1 hippocampus of the offspring rats is associated with increased long-term depression (LTD) and reduced expression of postsynaptic GluA2-containing α-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid receptors (AMPARs)...

Sleep-disordered breathing is more common in hypertensive disorders during pregnancy; however, most studies have not adequately accounted for the potential confounding impact of obesity. This study evaluated the frequency of sleep-disordered breathing in women with gestational hypertension and pre-eclampsia compared with body mass index- and gestation-matched normotensive pregnant women. Women diagnosed with gestational hypertension or pre-eclampsia underwent polysomnography shortly after diagnosis. Normotensive controls body mass index-matched within ±4 kg m-2 underwent polysomnography within ±4 weeks of gestational age of their matched case...

Orexin A (OXA) and B (OXB) are hypothalamic neuropeptides identified as regulators of food intake, energy homoeostasis, sleep-wake cycle and arousal. They also create an integrative link between energy homoeostasis and reproduction. Although their functions in the ovaries and testes have been partially explored, to date, less attention has been focused on the role of the peptides in the uterus. The aim of this study was to investigate the effect of one of orexins - orexin B on oestradiol (E2), oestrone (E1) and testosterone (T) secretion by porcine endometrial and myometrial slices as well as the gene expression of key steroidogenic enzymes responsible for steroid production (CYP17A1, CYP19A3) during the luteal phase of the oestrous cycle (days 10 to 11) and early pregnancy (days 10 to 11, 12 to 13, 15 to 16, 27 to 28)...

PURPOSE: Obstructive sleep apnea (OSA) is common in pregnancy, and may compromise fetal and even postnatal development. We developed an animal model to determine if maternal OSA could have lasting effects in offspring. METHODS: Pregnant Sprague Dawley rats were exposed to reduced ambient O2 from 21 to 4-5 %, approximately once/minute (chronic intermittent hypoxia - CIH) for 8 hours/day during gestation days 3-19. Similarly-handled animals exposed to ambient air served as controls (HC)...

The aim of this review is to clarify the interrelationship between melatonin and autism spectrum disorder (ASD) during fetal development. ASD refers to a diverse range of neurodevelopmental disorders characterized by social deficits, impaired communication, and stereotyped or repetitive behaviors. Melatonin, which is secreted by the pineal gland, has well-established neuroprotective and circadian entraining effects. During pregnancy, the hormone crosses the placenta into the fetal circulation and transmits photoperiodic information to the fetus allowing the establishment of normal sleep patterns and circadian rhythms that are essential for normal neurodevelopment...
