Postconception age at surgery as a predictor of ventriculoperitoneal shunt failure.

Objective: The gold standard of pediatric hydrocephalus management is the ventriculoperitoneal (VP) shunt. However, VP shunts have high failure rates, and both young age and prematurity have been identified as potential risk factors for shunt failure, although neither variable describes total development at the time of surgery. This study aimed to further characterize age and shunt failure through the use of postconception age at surgery (PCAS) as well as investigate the 40-week PCAS threshold initially described in 1999.

Male fathead minnow transcriptomes and associated chemical analytes in the Milwaukee estuary system.

Contaminants of Emerging Concern (CECs) can be measured in waters across the United States, including the tributaries of the Great Lakes. The extent to which these contaminants affect gene expression in aquatic wildlife is unclear. This dataset presents the full hepatic transcriptomes of laboratory-reared fathead minnows (Pimephales promelas) caged at multiple sites within the Milwaukee Estuary Area of Concern and control sites.

Integration of Adverse Outcome Pathways, Causal Networks and 'Omics to Support Chemical Hazard Assessment.

Several approaches have been used in an attempt to simplify and codify the events that lead to adverse effects of chemicals including systems biology, 'omics, assays and frameworks such as the Adverse Outcome Pathway (AOP). However, these approaches are generally not integrated despite their complementary nature. Here we propose to integrate toxicogenomics data, systems biology information and AOPs using causal biological networks to define Key Events in AOPs.

Impacts of maternal diet and exercise on offspring behavior and body weights.

Human and animal studies indicate that maternal obesity can negatively impact aspects of metabolism and neurodevelopment in the offspring. Not known, however, is whether maternal exercise can alter these adverse outcomes. In this study, Long-Evans female rats were provided a high fat (60%; HFD) or control diet (CD) 44days before mating and throughout gestation and lactation.
