Background: Despite recent work to characterize gene expression changes associated with larval development in oysters, the mechanism by which the larval shell is first formed is still largely unknown. In Crassostrea gigas, this shell forms within the first 24 h post fertilization, and it has been demonstrated that changes in...
BACKGROUND: The relationship between arsenic and birth weight is not well understood.
OBJECTIVE: To evaluate the causal relationship between prenatal arsenic exposure and birth weight considering the potential mediation effects of gestational age (GA) and maternal weight gain (MWG) during pregnancy using structural equation models (SEMs).
METHODS: A prospectively enrolled...
Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...

Disability is an emerging field within public health; people with significant disabilities account formore than 12% of the US population. Disparity status for this group would allow federal and state governments to actively work to reduce inequities. We summarize the evidence and recommend that observed differences are sufficient to meet...
BACKGROUND: Arsenic is an epigenetic toxicant and could influence fetal developmental programming.
OBJECTIVES: We evaluated the association between arsenic exposure and DNA methylation in maternal and umbilical cord leukocytes.
METHODS: Drinking-water and urine samples were collected when women were at <= 28 weeks gestation; the samples were analyzed for arsenic...
PURPOSE: To describe and compare the occurrence and co-occurrence of physical activity (PA), play, and object-related behaviors in toddlers with and without disabilities.
METHODS: Participants included 23 toddlers (21 with typical development (TD) and 2 with disabilities). Direct observation was used to describe the type and level of PA, play...
Background: When conducting research with American Indian tribes, informed consent beyond conventional institutional review board (IRB) review is needed because of the potential for adverse consequences at a community or governmental level that are unrecognized by academic researchers. Objectives: In this article, we review sovereignty, research ethics, and data-sharing considerations...
Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...
