Early adverse life-stress has been associated to behavioral disorders that can manifest as inappropriate or aggressive responses to social challenges. In this study, we analyzed the effects of artificial rearing on the open field and burial behavioral tests and on GFAP, c-Fos immunoreactivity and glucose metabolism measured in anxiety related brain areas. Artificial rearing of male rats was performed by supplying artificial milk through a cheek cannula and tactile stimulation, mimicking the mother's licking to rat pups from the 4(th) postnatal day until weaning...

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) is an easily accessible biomarker that has been reported to represent disease severity in adult trials. The aim of this study was to evaluate the relationship between culture positiveness and NLR in cases where the reason of sepsis was considered, and to foresight an idea about the active agents. METHODS: Preterm infants with birth weights ≤1500 g and/or ≤32 gestational weeks were eligible for this study...

In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus coordinates daily rhythms including sleep-wake, hormone release and gene expression. The cells of the SCN must synchronize to each other to drive these circadian rhythms in the rest of the body. The ontogeny of circadian cycling and intercellular coupling in the SCN remains poorly understood. Recent in vitro studies have recorded circadian rhythms from the whole embryonic SCN. Here, we tracked the onset and precision of rhythms in PERIOD2 (PER2), a clock protein, within the SCN isolated from embryonic and postnatal mice of undetermined sex...

BACKGROUND: Pregnant women's perceptions of the risks and benefits during mental health screening impact their willingness to disclose concerns. Early research in violence screening suggests that such perceptions may vary by mode of screening, whereby women view the anonymity of e-screening as less risky than other approaches. Understanding whether mode of screening influences perceptions of risk and benefit of disclosure is important in screening implementation. OBJECTIVE: The objective of this randomized controlled trial was to compare the perceptions of pregnant women randomized to a Web-based screening intervention group and a paper-based screening control group on the level of risk and benefit they perceive in disclosing mental health concerns to their prenatal care provider...

Early undernutrition causes long lasting alterations that affect the response to psychoactive drugs. Particularly, undernutrition during lactation affects the acute locomotor response to nicotine during adolescence, but the reward effect of continued exposure to nicotine remains unknown. The goal of this study was to investigate the effects of undernutrition during lactation on the nicotine susceptibility indexed via conditioned place preference (CPP), on dopamine content and turnover and on nicotine-induced nicotinic cholinergic receptor (nAChR) upregulation in the cerebral cortex, midbrain and hippocampus of adolescent mice...

Thermal manipulation during embryogenesis was previously reported to decrease the occurrence of ascites and to potentially improve cold tolerance of broilers. The objective of our study was to explore the effects of the interaction of cold incubation temperatures and cool ambient temperatures until 21 d of age on performance and body temperature. Ross 308 eggs were incubated either under control conditions I0 (37.6°C) or with cyclic cold stimulations I1 (6 h/d at 36.6°C from d 10 to 18 of incubation) or with 2 cold stimulations I2 (30 min at 15°C) at d 18 and 19 of incubation...

Genetic selection for high growth rate has resulted in tremendous changes not only in feed efficiency, but also in water consumption between modern broilers and their ancestor jungle fowl (JF). However molecular mechanisms involved in water homeostasis are still not well defined. This study aimed, therefore, to determine the effect of short-term water restriction on the expression of water channel- and noncoding RNA biogenesis-related genes in the kidney and whole blood of JF, broiler population from the 1990s (RB1995), and modern broiler population developed in 2015 (ARB2015)...

BackgroundHypoxic-ischemic encephalopathy (HIE) is a major cause of neonatal morbidity and mortality. Therapeutic hypothermia (TH) is the only available intervention, but neuroprotection is incomplete and variable. Seizures are common in infants with HIE undergoing TH and may worsen outcome. Phenobarbital is sometimes added, although use of prophylactic phenobarbital is controversial in the neonate. We hypothesize that prophylactic phenobarbital (PB) will not reduce, and may enhance, the neuroprotective effects of TH on brain injury and motor outcomes in the postnatal-day 10 (P10) hypoxic-ischemic (HI) rat...

A limited number of microRNAs (miRNAs, miRs) have been reported to control postnatal cardiomyocyte proliferation, but their strong regulatory effects suggest a possible therapeutic approach to stimulate regenerative capacity in the diseased myocardium. This study aimed to investigate the miRNAs responsible for postnatal cardiomyocyte proliferation and their downstream targets. Here, we compared miRNA profiles in cardiomyocytes between postnatal day 0 (P0) and day 10 (P10) using miRNA arrays, and found that 21 miRNAs were upregulated at P10, whereas 11 were downregulated...

Methods for detecting depression in fathers after the birth of their child are scarce. The Edinburgh Postnatal Depression Scale (EPDS), used to screen mothers for postpartum depression (PPD), lacks somatization and externalizing items. This potentially decreases its sensitivity in detecting depression in fathers, as many men actually express depression with somatization or externalizing symptoms. The present study assessed depressive symptoms in fathers of children 0-18 months old, and evaluated whether addressing both typical depression and externalizing, so-called "depressive equivalent" symptoms, might be more suitable for such assessment...

REVIEW

Adrenal catecholamine (CAT) secretion is a general physiological response of animals to environmental stressors such as hypoxia. This represents an important adaptive mechanism to maintain homeostasis and protect vital organs such as the brain. In adult mammals, CAT secretory responses are triggered by activation of the sympathetic nervous system that supplies cholinergic innervation of adrenomedullary chromaffin cells (AMC) via the splanchnic nerve. In the neonate, the splanchnic innervation of AMC is immature or absent, yet hypoxia stimulates a non-neurogenic CAT secretion that is critical for adaptation to extra-uterine life...

Identification of the causal effects of specific proteins on recurrent and partially reversible hearing loss has been difficult because of the lack of an animal model that provides reversible gene knockdown. We have developed the transgenic mouse line Actin-tTS::Nkcc1 (tetO/tetO) for manipulatable expression of the cochlear K(+) circulation protein, NKCC1. Nkcc1 transcription was blocked by the binding of a tetracycline-dependent transcriptional silencer to the tetracycline operator sequences inserted upstream of the Nkcc1 translation initiation site...

BACKGROUND: Women with comorbid depression and anxiety in the postpartum period experience more complex and severe symptoms than women with depression or anxiety alone; however, little is known about what influences these symptoms, especially among women from specific ethnic backgrounds. The objective of this study was to identify determinants of comorbid depression and anxiety symptomatology by 24 weeks postpartum in a cohort of Chinese-Canadian women. METHODS: A longitudinal cohort study was completed where 549 Chinese immigrant and Canadian-born women in Toronto were followed to 24 weeks postpartum...
