Children’s Nutrition Research Center Staff Publications

The aim of this study was to examine video-recorded observations of evening family mealtime at home among Mexican American children to help elucidate style of meal service, fathers' and mothers' feeding practices and child's eating behavior. Consistent with guidelines for coding behaviors, we analyzed observational data of evening mealtimes of 71 Mexican American children aged eight to 10 years. Regarding style of meal service, in almost all cases (96%), parents plated the child's food, with more available on the table or counter in 40% of the observations. Mothers almost always served the child (94%). Regarding parental feeding practices, parents used …

Effects Of Cumulative Trauma, Discrimination, And Racial Trauma Among African Americans, Brittany Renee Clayton

Theses and Dissertations

In the current study, we examined the impact of cumulative trauma, racial trauma, and everyday discrimination experiences within the African American community on psychological outcomes. One hundred and nineteen participants completed a series of self-report measures that analyzed their experiences of lifetime stressors, racial trauma, frequency of everyday discrimination, current posttraumatic stress disorder, depressive symptoms, and experiential avoidance levels. It was hypothesized that increased exposure to lifetime stressors, racial trauma events or experiences, and everyday discrimination would be associated with increased psychological distress. Correlations were conducted to identify and examine these relationships. This hypothesis was supported for lifetime stressor exposure …

Lianas Significantly Reduce Aboveground And Belowground Carbon Storage: A Virtual Removal Experiment, Sergio Estrada-Villegas, Sara Sofia Pedraza Navaez, Adriana Sanchez, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

Lianas are a quintessential tropical plant growth-form; they are speciose and abundant in tropical forests worldwide. Lianas compete intensely with trees, reducing nearly all aspects of tree performance. However, the negative effects of lianas on trees have never been combined and quantified for multiple tropical forests. Here, we present the first comprehensive standardized quantification of the effect of lianas on trees across tropical forests worldwide. We used data from 50 liana removal experiments and quantified the effect size of lianas on tree growth, biomass accretion, reproduction, mortality, leaf water potential, sap flow velocity, and leaf area index (LAI) across different …

Sex differences in aging occur in many animal species, and they include sex differences in lifespan, in the onset and progression of age-associated decline, and in physiological and molecular markers of aging. Sex differences in aging vary greatly across the animal kingdom. For example, there are species with longer-lived females, species where males live longer, and species lacking sex differences in lifespan. The underlying causes of sex differences in aging remain mostly unknown. Currently, we do not understand the molecular drivers of sex differences in aging, or whether they are related to the accepted hallmarks or pillars of aging or …

How Female Stem Undergraduate Students Form Their Science Identity, Todd Martin Medovich

All Theses And Dissertations

This qualitative case study describes how female science, technology, engineering, and mathematics (STEM) students choose their undergraduate major, the obstacles they faced when making that choice, and how they overcome gender-based obstacles. These descriptions illuminate the manner in which they form their science identity.

There is a gender gap in science, technology, engineering, and mathematics (STEM) disciplines (Viadero, 2009). This has been attributed to both biological and sociocultural causes. The biological basis for this disparity includes evidence of physiological differences between females and males, as well as the microaggressions and sexual harassment stemming from these differences (Bottia et al., 2015). …

Hematological measures are important intermediate clinical phenotypes for many acute and chronic diseases and are highly heritable. Although genome-wide association studies (GWAS) have identified thousands of loci containing trait-associated variants, the causal genes underlying these associations are often uncertain. To better understand the underlying genetic regulatory mechanisms, we performed a transcriptome-wide association study (TWAS) to systematically investigate the association between genetically predicted gene expression and hematological measures in 54,542 Europeans from the Genetic Epidemiology Research on Aging cohort. We found 239 significant gene-trait associations with hematological measures; we replicated 71 associations at p < 0.05 in a TWAS meta-analysis consisting of up to 35,900 Europeans from the Women's Health Initiative, Atherosclerosis Risk in Communities Study, and BioMe Biobank. Additionally, we attempted to refine this list of candidate genes by performing conditional analyses, adjusting for individual variants previously associated with hematological measures, and performed further fine-mapping of TWAS loci. To facilitate interpretation of our findings, we designed an R Shiny application to interactively visualize our TWAS results by integrating them with additional genetic data sources (GWAS, TWAS from multiple reference panels, conditional analyses, known GWAS variants, etc.). Our results and application highlight frequently overlooked TWAS challenges and illustrate the complexity of TWAS fine-mapping.

OBJECTIVE: The primary objective of this study was to ascertain the spectrum of genomic immunologic defects in PLPD. Secondary objectives included characterization of clinical outcomes and associations between genetic diagnoses and those outcomes.

METHODS: PLPD was defined by persistent lymphadenopathy, lymph organ involvement, or lymphocytic infiltration for more than 3 months, with or without chronic or significant Epstein-Barr virus (EBV) infection. Fifty-one subjects from …

Parent Perspectives On Preparing Students With Intellectual Disabilities For Inclusive Postsecondary Education, Jefferson Clark Sheen, Ty Aller, Robert L. Morgan, Kayla Currier Kipping

Sociology, Social Work and Anthropology Faculty Publications

Using a three-round Delphi survey, researchers explored parent perspectives regarding the personal competencies students with intellectual disabilities (ID) needed to be better prepared for participation in an Inclusive Postsecondary Education program (IPSE). An expert panel comprised of parents of students with ID in IPSE programs participated. Three Delphi rounds consisted of open-ended questions and cycles of subsequent rating scales on identified perspectives to establish a quantitative basis for consensus. The parent panel reached consensus on a list of 30 personal competencies that support student preparation for IPSE. A description of the methodology, results, and implications for practice are discussed.

Spatial Epidemiology: An Empirical Framework For Syndemics Research, Shikhar Shrestha, Cici X C Bauer, Brian Hendricks, Thomas J Stopka

Faculty, Staff and Student Publications

Syndemics framework describes two or more co-occurring epidemics that synergistically interact with each other and the complex structural social forces that sustain them leading to excess disease burden. The term syndemic was first used to describe the interaction between substance abuse, violence, and AIDS by Merrill Singer. A broader range of syndemic studies has since emerged describing the framework's applicability to other public health scenarios. With syndemic theory garnering significant attention, the focus is shifting towards developing robust empirical analytical approaches. Unfortunately, the complex nature of the disease-disease interactions nested within several social contexts complicates empirical analyses. In answering the …

Craniofacial Fluctuating Asymmetry In Gorillas, Chimpanzees, And Macaques, Ashly N. Romero, D. Rex Mitchell, Siobhán B. Cooke, Claire A. Kirchhoff, Claire E. Terhune

Biomedical Sciences Faculty Research and Publications

Objectives

Craniofacial fluctuating asymmetry (FA) refers to the random deviations from symmetry exhibited across the craniofacial complex and can be used as a measure of developmental instability for organisms with bilateral symmetry. This article addresses the lack of data on craniofacial FA in nonhuman primates by analyzing FA magnitude and variation in chimpanzees, gorillas, and macaques. We offer a preliminary investigation into how FA, as a proxy for developmental instability, varies within and among nonhuman primates.

Cell viability, clonogenic, and anchorage-independent growth assays as well as an orthotopic mouse model of PDAC were used to evaluate the biological relevance of CES2 in pancreatic cancer. CES2-driven metabolic changes were determined by untargeted and targeted …

Effects Of Placebo Administration On Immune Mechanisms And Relationships With Central Endogenous Opioid Neurotransmission, Alan Prossin, Alisa Koch, Phillip Campbell, Geoffroy Laumet, Christian S Stohler, Robert Dantzer, Jon-Kar Zubieta

Faculty, Staff and Student Publications

Behavioral conditioning and expectation can have profound impact on animal and human physiology. Placebo, administered under positive expectation in clinical trials, can have potent effects on disease pathology, obscuring active medications. Emerging evidence suggests placebo-responsive neurotransmitter systems (e.g., endogenous opioid) regulate immune function by manipulating inflammatory proteins including IL-18, a potent pro-inflammatory, nociceptive cytokine implicated in pathophysiology of various diseases. Validation that neuroimmune interactions involving brain μ-opioid receptor (MOR) activity and plasma IL-18 underlie placebo analgesic expectation could have widespread clinical applications. Unfortunately, current lack of mechanistic clarity obfuscates clinical translation. To elucidate neuroimmune interactions underlying placebo analgesia, we exposed …
