Mitochondria-associated endoplasmic reticulum membranes (MAMs) regulate important cellular functions including calcium signaling, bioenergetics, and apoptosis during neurodevelopment and carcinogenesis, but its function in male reproduction and spermatogenesis remains enigmatic because the field lacks a complete understanding of the proteome within testis MAMs. To better understand the biological processes and molecular functions of MAM in testes, here, we report a global mass spectrometry-based proteomic evaluation of the MAM obtained from human testes, mouse testes and brains, respectively...

The amount, composition, and sources of nutrition support provided to preterm infants is critical for normal growth and development, and particularly for structural and functional neurodevelopment. Although omega-3 long chain polyunsaturated fatty acids (LC-PUFA), and particularly docosahexanoic acid (DHA), are considered of particular importance, results from clinical trials with preterm infants have been inconclusive because of ethical limitations and confounding variables. A translational large animal model is needed to understand the structural and functional responses to DHA...

There is a growing research interest on the antenatal features of children with neurodevelopmental disorders. Indeed, it has been proved that the neurodevelopment is, at least partly, affected by processes occurring in fetal life and that the early neurodevelopmental disorders identification is essential to optimize long-term outcomes. This systematic review aims to summarize findings on antenatal ultrasound data, which are or might be considered early risk indexes of postnatal social impairments. We conducted systematic searches in Pubmed and PsychINFO databases to identify studies including fetal ultrasound measurements and postnatal neurodevelopmental outcome assessment...

Interplay between genetic and environmental factors during critical time windows can have effects that span from neurodevelopment to neurodegeneration. We present the concept of the 'neuroexposome', emphasizing the brain's distinctive response to environmental exposure, and how current 'omics' sciences can inform on both disease pathogenesis and future public health policies.

In spite of many association studies linking gene polymorphisms and mutations of L-type Voltage-Gated Ca2+ Channels (VGCC) in neurodevelopmental disorders, such as autism and schizophrenia, specific L-type VGCC roles during brain development remain unclear. Yet, calcium signaling has been shown to be essential for neurodevelopmental processes such as sculpting of neurites, functional wiring and fine tuning of growing networks. To bridge this gap, we performed submembraneous calcium imaging using a membrane-tethered genetically-encoded calcium indicator (GECI) Lck-G-CaMP7...

The Adolescent Brain Cognitive Development Study (ABCD) will capture a breadth of multi-faceted biobehavioral, environmental, familial, and genetic longitudinal developmental open-access data from over 11,000 9-10 year olds throughout the United States of America (USA) for an envisioned ten-year span. This will subsequently represent the largest study ever attempted with this level of brain phenotypic detail. This study holds the opportunity for exciting advances in the understanding of typical adolescent neurodevelopment, discovery of neurodevelopmental underpinnings of mental illness, as well as the neurodevelopmental influences of (and on) social factors, substance use, and critically - their interaction...

Microglial cells in the central nervous system play important roles in neurodevelopment and resistance to infection, yet microglia can become neurotoxic under some conditions. An early event during prion infection is the activation of microglia and astrocytes in the brain prior to damage or death of neurons. Previous prion disease studies using two different strategies to manipulate signaling through the microglial receptor CSF-1R reported contrary effects on survival from prion disease. However, in these studies, reduction of microglial numbers and function were variable, thus confounding interpretation of the results...

The gene encoding the chromatin remodeler CHD8 is the most frequently mutated gene in individuals with autism spectrum disorder (ASD). Heterozygous mutations in CHD8 give rise to ASD that is often accompanied by macrocephaly, gastrointestinal complaints, and slender habitus. Whereas most phenotypes of CHD8 haploinsufficiency likely result from delayed neurodevelopment, the mechanism underlying slender habitus has remained unknown. Here, we show that CHD8 interacts with CCAAT/enhancer-binding protein β (C/EBPβ) and promotes its transactivation activity during adipocyte differentiation...

Accumulating studies have defined a role for the intestinal microbiota in modulation of host behavior. Research using gnotobiotic mice emphasizes that early microbial colonization with a complex microbiota (conventionalization) can rescue some of the behavioral abnormalities observed in mice that grow to adulthood completely devoid of bacteria (germ-free mice). However, the human infant and adult microbiomes vary greatly, and effects of the neonatal microbiome on neurodevelopment are currently not well understood...

Thyroid hormones are crucial in normal brain development. Transient and mild thyroid hormone insufficiency in pregnancy is also associated with impaired neurodevelopment in the offspring (e.g., 3-4 IQ score loss in association with maternal free thyroxine in the lowest fifth percentile). While inadequate iodine intake remains the most common underlying cause of mild thyroid hormone insufficiency in vulnerable populations including pregnant women, other factors such as exposure to environmental contaminants have recently attracted increasing attention, in particular in interaction with iodine deficiency...

Due to the increasing volume of oil sands process-affect water (OSPW) and its toxicity to aquatic organisms, it is important to fully understand its effects and study remediation processes that will enable its release to the environment. Ozone treatment is currently being considered as a tool to expedite remediation, as it is known to degrade toxic organic compounds present in OSPW. In this study, we aimed to measure the effects of OSPW exposure on the growth, development and recovery of zebrafish (Danio rerio) embryos...

Mutations in the GNAO1 gene cause a complex constellation of neurological disorders including epilepsy, developmental delay, and movement disorders. GNAO1 encodes Gαo , the α subunit of Go , a member of the Gi/o family of heterotrimeric G protein signal transducers. Go is the most abundant membrane protein in the mammalian central nervous system and plays major roles in synaptic neurotransmission and neurodevelopment. GNAO1 mutations were first reported in early infantile epileptic encephalopathy 17 (EIEE17) but are also associated with a more common syndrome termed neurodevelopmental disorder with involuntary movements (NEDIM)...

Context: Low maternal free thyroxine (FT4) has been associated with poor child neurodevelopment in some single-centre studies. Evidence remains scarce for potential adverse effects of high FT4 and whether associations differ in countries with a different iodine status. Objective: To assess the association of maternal thyroid function in early pregnancy with child neurodevelopment in countries with a different iodine status. Design, Setting and Participants: Meta-analysis of individual-participant data compromising 9,036 mother-child pairs from three prospective population-based birth cohorts: INMA (Spain), Generation R (The Netherlands) and ALSPAC (United Kingdom)...

Conflict adaptation is key in how children self-regulate and assert cognitive control in a given situation compared with a previous experience. In the current study, we analyzed event-related potentials (ERPs) to identify age-related differences in conflict adaptation. Participants of different ages (5-year-old children, 10-year-old children, and adults) were subjected to a stimulus-stimulus (S-S) conflict control task (the flanker task) and a stimulus-response (S-R) conflict control task (the Simon task). The behavioral results revealed that all age groups had reliable conflict adaptation effects (CAEs), with faster response times on current incongruent trials preceded by incongruent trials (iI trials) compared with current incongruent trials preceded by congruent trials (cI trials)...

BACKGROUND: Patients with congenital heart disease are at risk of motor, cognitive, speech, and feeding difficulties after cardiac surgery. Rehabilitation therapy could improve functional outcomes in this population if applied in the acute postcardiac surgical in-hospital stay. However, information on the types of acute postcardiac surgery therapy needs in children is scarce. Our goal was to describe rehabilitation therapy following congenital heart surgery and pre/intraoperative factors associated with need for therapy...

Glucocorticoids (GC) have first been shown to originate from the adrenal glands where synthesis and release is controlled by the hypothalamic-pituitary-adrenal (HPA) axis. Recently, it was shown that GC and other steroid hormones are also synthesized in the central nervous system, so-called neurosteroids. GC bind to specific GC receptors (GR) which function as ligand-activated transcription factors. GR are expressed in nearly all cell types in the brain, and therefore GC have a strong impact on neuronal development...
