Abstract
Perinatal exposure to bifenthrin (BF) alters neurodevelopment. However, the most susceptible time period to BF exposure and the possible mechanisms are not clear. In the current study, pregnant female mice were treated with BF (0.5 mg/kg/d) at three different stages [gestational day (GD) 0-5, 6-15 and 16-birth (B)] and neurologic deficits were evaluated in offspring mice. BF exposure at GD 16-B significantly altered the locomotor activity and caused learning and memory impairments in 6-week-old offspring. Gestational BF exposure also caused neuronal loss in the region of cornu ammonis of hippocampi of 6-week-old offspring. Interestingly, neurobehavioral impairments and neuronal loss were not observed in offspring at 10-week-old. BF exposure at GD 16-B also decreased protein levels of VGluT1, NR1 and NR2A while increased the protein levels of NR2B and VGAT1, as well as the gene levels of Il-1β, Il-6 and Tnf-α in hippocampi of 6-week-old offspring. Collectively, these data demonstrate that gestational exposure to a low dose BF causes neurodevelopmental deficits that remit with the age and the late-stage of pregnancy is the most susceptible time window to BF exposure. Imbalance in excitatory/inhibitory neuronal transmission, altered expression levels of NMDA receptors and increased neural inflammation may be associated with BF prenatal exposure-triggered neurobehavioral impairments.

Abstract
Maternal infection during pregnancy is considered a key risk factor for developing schizophrenia in offspring. There is evidence that maternal exposure to infectious agents is associated with fetal zinc deficiency. Due to the essential role of zinc in brain function and development, in the present study, we activated maternal immune system using lipopolysaccharide (LPS) as a model of schizophrenia to examine whether zinc supplementation throughout pregnancy can reverse LPS-induced deleterious effects. To test the hypothesis, pregnant rats were treated with intraperitoneal injection of either saline or LPS (0.5 mg/kg) at gestational day 15 and 16, and zinc supplementation (30 mg/kg) was administered throughout pregnancy by gavage. At postnatal day 60, Y-maze was used to evaluate working memory of offspring. Moreover, the expression levels of catechol O-methyltransferase (COMT) and glutamate decarboxylase 67 (GAD67) were measured in the frontal cortex of the brain samples. Only male offspring prenatally exposed to LPS showed a significant impairment in working memory. In addition, prenatal LPS exposure causes a moderate decrease in GAD67 expression level in the male pups, while COMT expression was found unchanged. Interestingly, zinc supplementation restored the alterations in working memory as well as GAD67 mRNA level in the male rats. No alteration was detected for neither working memory nor COMT/GAD67 genes expression in female offspring. This study demonstrates that zinc supplementation during pregnancy can attenuate LPS-induced impairments in male pups. These results support the idea to consume zinc supplementation during pregnancy to limit neurodevelopmental deficits induced by infections in offspring.

Abstract
Neurodevelopmental deficits are postulated to play an important role in the etiology of persistent antisocial behavior (ASB). Yet it remains uncertain as to which particular deficits are most closely associated with ASB. We seek to advance this understanding using prospectively collected data from a birth cohort in which multiple indices of neurodevelopmental functioning and ASB were assessed. Participants (n = 2776) were members of the Providence, Rhode Island cohort of the Collaborative Perinatal Project. Information on demographic and neurodevelopmental variables was collected from pregnancy through age 7. When all offspring had reached 33 years of age an adult criminal record check was conducted. A subset of subjects also self-reported on their engagement in serious ASB. Bivariate logistic regression was used to examine the relationship between each neurodevelopmental factor and adult ASB and test whether associations varied depending on how ASB was ascertained. After controlling for background and contextual characteristics, maternal smoking during pregnancy, lower childhood verbal and performance IQ, and age 7 aggressive/impulsive behavior all significantly increased the odds of adult ASB. Associations were not modified by sex and did not depend on how ASB was assessed. However, while both males and Black participants were more likely to engage in ASB than their respective female and White counterparts, relationships were significantly stronger for official records than for self-reports. Results point to a particular subset of early neurodevelopmental risks for antisocial outcomes in adulthood. Findings also suggest that prior contradictory results are not due to the use of official records versus self-reported outcomes.

Abstract
Studies in mice with deficient antioxidative enzymes have shown that physiological levels of reactive oxygen species (ROS) can adversely affect the developing embryo and fetus. Herein, DNA repair-deficient progeny of oxoguanine glycosylase 1 (ogg1)-knockout mice lacking repair of the oxidative DNA lesion 8-oxo-2'-deoxyguanosine (8-oxodGuo) exhibited enhanced postnatal neurodevelopmental deficits, revealing the pathogenic potential of 8-oxodGuo initiated by physiological ROS production in fetal brain and providing the first evidence of a pathological phenotype for ogg1-knockout mice. Moreover, when exposed in utero to ethanol (EtOH), ogg1-knockout progeny exhibited higher levels of 8-oxodGuo in fetal brain and more severe postnatal neurodevelopmental deficits than wild-type littermates, both of which were blocked by pretreatment with the free radical trapping agent phenylbutylnitrone. These results suggest that ROS-initiated DNA oxidation, as distinct from altered signal transduction, contributes to neurodevelopmental deficits caused by in utero EtOH exposure, and fetal DNA repair is a determinant of risk.

Abstract
Binge-like alcohol exposure during the early postnatal period in rats and mice causes deficits in spatial learning and memory that persist into adulthood. Wozniak et al. (2004) reported that heavy binge alcohol exposure on postnatal day 7 (PD 7) in C57BL/6 (B6) mice produced profound spatial learning deficits in the Morris water maze when tested in adolescence (P30-39); when tested in adulthood, however, the deficits were greatly attenuated. Using a similar PD 7 binge alcohol exposure paradigm in B6 mice, we tested whether a single-day (PD 7 only) alcohol treatment produced place learning deficits in both adolescence and in adulthood, and further tested whether a more extended (3-day, PD 7-9) alcohol exposure would induce more severe and enduring deficits. B6 mice were given either 2 subcutaneous injections of alcohol (2.5 g/kg each) 2 h apart on PD 7 or on PD 7-9, and compared with controls that received saline vehicle injections and controls that received no injections. The alcohol injections on PD 7 produced average peak blood alcohol concentrations of 472 mg/dL and evoked typical patterns of activated caspase-3-positive neurons in the cortex, hippocampal formation, and striatum 6 h after the last injection. Mice were given standard place training or random location training in the Morris water maze either as adolescents (PD 30-39) or adults (PD 70-79). The adolescents acquired the place learning more slowly than adults, and the alcohol treatments produced only modest place acquisition deficits. In contrast, both the PD7 and the PD 7-9 alcohol treatments resulted in large and significant spatial learning impairments in adults. In contrast to the previous findings of Wozniak et al. (2004), these results indicate that binge alcohol exposure in the 3rd trimester equivalent produces significant and enduring deficits in spatial learning in B6 mice.

Abstract
Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that mediates protective responses to oxidative stress, but its developmental role is unknown. Herein, we treated pregnant Nrf2-deficient knockout mice with methamphetamine (METH) (5-40 mg/kg ip), which increases fetal reactive oxygen species (ROS) and oxidatively damaged DNA in fetal brain tissue. METH-exposed Nrf2(-/-) fetuses were unable to increase mRNA levels of ROS-protective heme oxygenase-1, NAD(P)H:quinone oxidoreductase, or oxoguanine glycosylase 1, unlike wild-type controls, and exhibited enhanced DNA oxidation, fetal resorption, edema, and reduced fetal weight, with greater toxicity in female Nrf2(-/-) fetuses. Postnatal neurodevelopmental deficits in activity and olfactory function were exacerbated, with gender-dependent differences, and the olfactory bulb GABAergic marker GAD-65 was decreased in Nrf2(-/-) offspring exposed in utero to METH. In utero METH-initiated olfactory deficits may be a sensitive postnatal functional test for long-term neurotoxicity, and indicated a broad fetal role for Nrf2. The results show that fetal Nrf2 deficiency enhances METH-initiated oxidative DNA damage and toxicity, suggesting that Nrf2 activation of cytoprotective proteins mitigates the effects of ROS and their oxidative damage to cellular macromolecules, thereby protecting the developing fetus from adverse structural and postnatal neurodevelopmental consequences.
