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 ...

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 ...

The Association of Prenatal Exposure to Perfluorinated Chemicals with Glucocorticoid and Androgenic Hormones in Cord Blood Samples: The Hokkaido Study

Environmental Health Perspectives, 2016
Background: Perfluorinated chemicals (PFCs) disrupt cholesterol homeostasis. All steroid hormones are derived from cholesterol, and steroid hormones such as glucocorticoids and androgenic hormones mediate several vital physiologic functions. However, the

Serious Infections in Offspring Exposed to Tumor Necrosis Factor Inhibitors During Pregnancy: Comparison of Timing During Pregnancy and Placental Transfer Ability

Arthritis &Rheumatology, EarlyView.
Objective We evaluated serious infection risk in offspring exposed to tumor necrosis factor inhibitors (TNFi) in utero, separated by TNFi timing and placental transfer ability. Methods Using MarketScan (2011–2021), we identified offspring born to mothers with chronic inflammatory diseases.

Parental involvement and engagement during COVID‐19 lockdowns: School staff and parents' reflections about children's learning at home

British Educational Research Journal, EarlyView.
Abstract Valuing parental engagement, as part of home–school collaboration, can benefit children's learning. This article focuses on parents and school‐based staff's (N = 120) experiences of children's learning occurring at home during the COVID‐19 lockdowns (2020–2021), both school‐mandated and other learning activities.

Prenatal Exposure to Perfluoroalkyl Substances and Behavioral Development in Children

International Journal of Environmental Research and Public Health, 2016
Background: In recent years, prevalence rates of behavioral disorders in children have increased. One factor possibly implied in the etiology of behavioral disorders is exposure to perfluoroalkyl substances (PFASs).

Brain Health for Children

Brain Health, EarlyView.
ABSTRACT The World Health Organization (WHO) defines brain health as the maintenance of optimal brain integrity, good mental state, and cognitive function without significant neuropsychiatric disease. Early childhood is a critical period for brain development, which were influenced by early experiences, nutrition, and environmental factors. Disruptions

Adults prenatally exposed to the Dutch Famine exhibit a metabolic signature associated with a broad spectrum of common diseases

BMC Medicine
Background Exposure to famine in the prenatal period is associated with an increased risk of metabolic disease, including obesity and type 2 diabetes. We employed nuclear magnetic resonance (NMR) metabolomic profiling to identify the metabolic changes ...
