Developmental Lead and/or Prenatal Stress Exposures Followed by Different Types of Behavioral Experience Result in the Divergence of Brain Epigenetic Profiles in a Sex, Brain Region, and Time-Dependent Manner: Implications for Neurotoxicology. [PDF]

, 2017
Over a lifetime, early developmental exposures to neurocognitive risk factors, such as lead (Pb) exposures and prenatal stress (PS), will be followed by multiple varied behavioral experiences.

Evaluation of IHH, PTCH1, and SMO protein immunohistochemistry in the human mandibular condyle at fetal stages from 30 to 80 mm greatest length

The Anatomical Record, EarlyView.
Abstract This study evaluated the morphogenesis of the temporomandibular joint (TMJ) in human fetuses during the third month of gestation through the analysis of immunohistochemistry for the proteins Indian Hedgehog (IHH), Patched‐1 (PTCH1), and Smoothened (SMO).

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Prenatal environmental tobacco smoke exposure: a predictor of blood selenium levels in children

Frontiers in Public Health
IntroductionThe aim of the study was to investigate the relationship between prenatal environmental tobacco smoke (ETS) exposure and blood selenium concentration (Se-B) in a selected group of children.MethodsA total of 299 children were recruited for ...

Maternal prenatal substance use and behavior problems among children in the U.S. [PDF]

Prenatal exposure to smoking and alcohol-use is found to be correlated with various adverse consequences for children, including behavior problems. However, it is not clear whether this relationship is an artifact of underlying confounding factors that ...

Prenatal Lead Exposure Risk Assessment by Vermont Maternity Care Providers [PDF]

, 2017
Introduction. One percent of women of childbearing age in the U.S. have blood lead levels ≥ 5 ug/dL, which are associated with maternal hypertension during pregnancy, neural tube and cardiac defects in infants, low birth weight, prematurity, and ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Prenatal exposure to extremely low frequency magnetic field and its impact on fetal growth

Environmental Health, 2019
Objective Studies on the effect of prenatal exposure to magnetic field (MF) on fetal growth is inconclusive and subject to some methodological limitations, particularly in measurement of MF exposure.

Interval Timing Is Altered in Male Nrxn1+/− Mice: A Model of Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is characterized by impaired social interactions and communication, and increased repetitive and stereotypical behavior. Neuroimaging shows functional abnormalities in brain areas involved in temporal processing in autistic individuals, and they also show deficits in interval timing.
