Magnesium sulfate (MgSO4) administration to mothers at risk of preterm delivery is proposed as a neuroprotective strategy against neurological alterations such as cerebral palsy in newborns. However, long-term beneficial or adverse effects of MgSO4 and sex-specific sensitivity remain to be investigated. We conducted behavioral and neurochemical studies of MgSO4 effects in males and females, from the perinatal period to adolescence in a mouse model of cerebral neonatal lesion. The lesion was produced in 5-day-old (P5) pups by ibotenate intracortical injection...

BACKGROUND: The proapoptotic molecule BAX, plays an important role in mitochondrial apoptotic pathway. Dorsal root ganglion (DRG) neurons depend on neurotrophic factors for survival at early developmental stages. Withdrawal of neurotrophic factors will induce apoptosis in DRG neurons, but this type of cell death can be delayed or prevented in neonatal Bax knockout (KO) mice. In adult animals, evidence also shows that DRG neurons are less dependent upon neurotrophic factors for survival...

Exposure to excessive oxygen in survivors of preterm birth is one of the factors that underlie the adverse neurological outcome in later life. Various pathological changes including enhanced apoptotic activity, oxidative stress and inflammation as well as decreased neuronal survival has been demonstrated in animal models of neonatal hyperoxia. The aim of the present study was to investigate the effect of administering uridine, an anti-apoptotic agent, on cellular, molecular and behavioral consequences of hyperoxia-induced brain damage in a neonatal rat model...

Histone deacetylase (HDAC) plays a role in synaptic plasticity and long-term memory formation. We hypothesized that trichostatin-A (TSA), an HDAC inhibitor, would promote long-term odor preference memory and maintain enhanced GluA1 receptor levels that have been hypothesized to support memory. We used an early odor preference learning model in neonate rat pups that normally produces only 24-h memory to test behavior and examine receptor protein expression. Our behavioral studies showed that intrabulbar infusion of TSA, prior to pairing of the conditioned stimulus (peppermint odor) with the unconditioned stimulus (tactile stimulation), prolonged 24-h odor preference memory for at least 9 d...

BACKGROUND: Carbon-dioxide (CO2)-pneumothorax during minimally invasive surgery induces well-known metabolic changes. However, little is known about its impact on the central nervous system. The aim of this work is to evaluate the acute impact of CO2-pneumothorax over central cytokine response and its long-term effect on animal behavior. METHODS: This is an experimental study where neonatal Sprague-Dawley rats are submitted to CO2-pneumothorax. Peripheral and central cytokine response was evaluated 24h after insufflation, and peripheral immune cell phenotyping was evaluated 24h and 4weeks post-insufflation...

Oral gavage is a popular route of drug administration during preclinical testing. Despite the growing body of information regarding the effects of oral gavage and the stress associated with this technique, the consequences of such exposure during pregnancy or lactation have rarely been investigated. Therefore, we sought to determine the consequences of oral gavage exposure during pregnancy and lactation on the neurodevelopment and behavior of rat offspring. Pregnant Sprague-Dawley dams underwent either no treatment or oral gavage of distilled water once daily from gestational day 7 until postnatal day 21...

Chagas disease is a neglected tropical disease that continues to affect populations living in extreme poverty in Latin America. After successful vector control programs, congenital transmission remains as a challenge to disease elimination. We used the PRECEDE-PROCEED planning model to develop strategies for neonatal screening of congenital Chagas disease in rural communities of Guatemala. These communities have persistent high triatomine infestations and low access to healthcare. We used mixed methods with multiple stakeholders to identify and address maternal-infant health behaviors through semi-structured interviews, participatory group meetings, archival reviews and a cross-sectional survey in high risk communities...

OBJECTIVES: Ovarian hormones (OH) and early malnutrition may affect the developing brain, with repercussions on behavioral and excitability-dependent processes. However, the possible synergistic effects of both factors have not been analyzed. In this study, we investigated the effect of treatment in early life with OH and suckling among distinct litter sizes on recognition memory, anxiety behavior, and the excitability-dependent phenomenon known as cortical spreading depression (CSD)...

In the developing hypothalamus, the fat-derived hormone leptin stimulates the growth of axons from the arcuate nucleus of the hypothalamus (ARH) to other regions that control energy balance. These projections are significantly reduced in leptin deficient (Lep(ob/ob) ) mice and this phenotype is largely rescued by neonatal leptin treatments. However, treatment of mature Lep(ob/ob) mice is ineffective, suggesting that the trophic action of leptin is limited to a developmental critical period. To temporally delineate closure of this critical period for leptin-stimulated growth, we treated Lep(ob/ob) mice with exogenous leptin during a variety of discrete time periods, and measured the density of Agouti-Related Peptide (AgRP) containing projections from the ARH to the ventral part of the dorsomedial nucleus of the hypothalamus (DMHv), and to the medial parvocellular part of the paraventricular nucleus (PVHmp)...

BACKGROUND: Sevoflurane anesthesia is widely used in pediatric patients. In this study, we investigated whether early multiple exposures to sevoflurane induced cognitive dysfunction by altering the hippocampal expression of ApoE later in development. METHODS: Sprague-Dawley rats were exposed to 2.6% sevoflurane at postnatal day 7 (P7), P14, and P21 for 2 h. The ability of learning and memory was assessed using the Morris water maze at P37 and P97. The hippocampal volume was measured by magnetic resonance imaging (MRI) at P37 and P97...

The objective of this study was to verify whether repeated morphine administration and maternal deprivation in early life alter neurobehavioral development and central nerve growth factor (NGF) levels. A total of 58 male Wistar rat pups were used in our study. From postnatal day 1 (P1), litters were daily deprived of their mother for 3hours; this was continued for the first 10days of life. Animals were divided into 5 groups: total control (C), did not receive any intervention; saline (S), received saline solution; morphine (M), received morphine; deprived-saline group (DS), were subjected to maternal deprivation and received saline solution; and deprived-morphine (DM), were subjected to maternal deprivation and received morphine...

This review is based on literature on prenatal anxiety effects that was found on Pubmed and PsycINFO for the years 2010-2016. Prenatal anxiety is thought to have distinct features, although it has been measured both by specific prenatal anxiety symptoms as well as by standardized anxiety scales. Its prevalence has ranged from 21 to 25% and it has been predicted by a number of pregnancy - related variables such as unintended pregnancy, demographic variables such as low acculturation and income and psychosocial factors including pessimism and partner tension...

Loss of GABAergic inhibition in pain pathways has been considered to be a key component in the development of chronic pain. In the present study, we intended to examine if miR-92b-mediated post-transcriptional dysregulation of spinal potassium chloride cotransporter (KCC2) and vesicular GABA transporter (VGAT) plays a major role in the development and maintenance of long-term visceral hyperalgesia in neonatal zymosan-treated rats. Neonatal cystitis was induced by transurethral zymosan administration from postnatal (P) days 14-16 (protocol 1)...

BACKGROUND: In conditions of immunosuppression, the central nervous sty 5ystem (CNS) is the main target tissue for the reactivation of infection by Trypanosoma cruzi, the causative agent of Chagas disease. In experimental T. cruzi infection, interferon gamma (IFNγ)(+) microglial cells surround astrocytes harboring amastigote parasites. In vitro, IFNγ fuels astrocyte infection by T. cruzi, and IFNγ-stimulated infected astrocytes are implicated as potential sources of tumor necrosis factor (TNF)...

Horses are a precocious species that must accomplish several milestones that are critical to survival in the immediate post-birth period for their survival. One essential milestone is the successful transition from the intrauterine unconsciousness to an extrauterine state of consciousness or awareness. This transition involves a complex withdrawal of consciousness inhibitors and an increase in neuroactivating factors that support awareness. This process involves neuroactive hormones as well as inputs related to factors such as cold, visual, olfactory, and auditory stimuli...
