Prenatal Stress and Socioeconomic Status as Predictors of Placental Methylation in Pregnant People
Peer reviewed Peer reviewed
Direct linkDirect link
Czenilriene J. Santander; Sharon Y. Lee; Gloria Peters; Carmen J. Marsit; Laura R. Stroud – Merrill-Palmer Quarterly: A Peer Relations Journal, 2024
Despite growing interest in placental epigenetics, the combined impact of prenatal stress and socioeconomic status on placental methylation is still largely understudied. We conducted a study to examine the associations of prenatal stress and socioeconomic factors (household income, Hollingshead socioeconomic index) with placental methylation.…

Modeling the Contribution of Genetic Variation to Cognitive Gains Following Training with a Machine Learning Approach
Peer reviewed Peer reviewed
Direct linkDirect link
Musso, Mariel F.; Cómbita, Lina M.; Cascallar, Eduardo C.; Rueda, M. Rosario – Mind, Brain, and Education, 2022
The objective of this research was to develop robust predictive models of the gains in working memory (WM) and fluid intelligence (Gf) following executive attention training in children, using genetic markers, gender, and age variables. We explore the influence of genetic variables on individual differences in susceptibility to intervention.…

Developmental Changes in Plasticity, Synaptic, Glia, and Connectivity Protein Levels in Rat Medial Prefrontal Cortex
Peer reviewed Peer reviewed

Jia, Margaret; Travaglia, Alessio; Pollonini, Gabriella; Fedele, Giuseppe; Alberini, Cristina M. – Learning & Memory, 2018
The medial prefrontal cortex (mPFC) plays a critical role in complex brain functions including decision-making, integration of emotional, and cognitive aspects in memory processing and memory consolidation. Because relatively little is known about the molecular mechanisms underlying its development, we quantified rat mPFC basal expression levels…

Influence of the Perceived Taste Intensity of Chemesthetic Stimuli on Swallowing Parameters Given Age and Genetic Taste Differences in Healthy Adult Women
Peer reviewed Peer reviewed
Direct linkDirect link
Pelletier, Cathy A.; Steele, Catriona M. – Journal of Speech, Language, and Hearing Research, 2014
Purpose: This study examined whether the perceived taste intensity of liquids with chemesthetic properties influenced lingua-palatal pressures and submental surface electromyography (sEMG) in swallowing, compared with water. Method: Swallowing was studied in 80 healthy women, stratified by age group and genetic taste status. General Labeled…

Antagonistic Pleiotropy at the Human "IL6" Promoter Confers Genetic Resilience to the Pro-Inflammatory Effects of Adverse Social Conditions in Adolescence
Peer reviewed Peer reviewed
Direct linkDirect link
Cole, Steven W.; Arevalo, Jesusa M. G.; Manu, Kavya; Telzer, Eva H.; Kiang, Lisa; Bower, Julienne E.; Irwin, Michael R.; Fuligni, Andrew J. – Developmental Psychology, 2011
The authors tested the evolutionary genetic hypothesis that the functional form of an asymmetrically risky Gene x Environment interaction will differ as a function of age-related antagonistic pleiotropy (i.e., show opposite effects in young vs. old individuals). Previous studies have identified a polymorphism in the human "IL6" promoter…

Platelet Serotonin, A Possible Marker for Familial Autism.
Peer reviewed Peer reviewed
Piven, Joseph; And Others – Journal of Autism and Developmental Disorders, 1991
Platelet serotonin (5HT) levels of 5 autistic subjects (ages 16-37) who had siblings with either autism or pervasive developmental disorder were significantly higher than levels of 23 autistic subjects without affected siblings. Autistic subjects without affected siblings had 5HT levels significantly higher than 10 normal controls. Sex, age, and…
