The Ci-Asd Program: Implementation Of Contextual Interventions For Autism Spectrum Disorder (Ci-Asd) With Latino Families (Preliminary Report), Gabriel Gonzalez, Erik Pérez, Angela Blackwell Apr 2024

The Ci-Asd Program: Implementation Of Contextual Interventions For Autism Spectrum Disorder (Ci-Asd) With Latino Families (Preliminary Report), Gabriel Gonzalez, Erik Pérez, Angela Blackwell

Spring 2024 Virtual OTD Capstone Symposium

Children diagnosed with Autism Spectrum Disorder (ASD) experience sensory processing differences that affect their participation in daily activities and routines. Autism affects an estimated 1 in 36 children in the U.S. However, Latino children are diagnosed two years later than white children. Latino families still have the greatest disparities in accessing ASD resources throughout the U.S. compared to white families. The lack of ASD services and resources led to decreased parental self-efficacy, quality of life, and increased child behavioral problems.

Contextual Interventions Adapted for Autism Spectrum Disorder (CI-ASD) are an emerging intervention for occupational therapy (OT) practitioners. Recent literature shows …

Cell-Type Specific Molecular Expression Levels By Restricted-Dimensional Cytometry, David Kaplan, Hillard M. Lazarus Apr 2024

Cell-Type Specific Molecular Expression Levels By Restricted-Dimensional Cytometry, David Kaplan, Hillard M. Lazarus

Faculty Scholarship

Background: Cytometric analysis has been commonly used to delineate distinct cell subpopulations among peripheral blood mononuclear cells by the differential expression of surface receptors. This capability has reached its apogee with high-dimensional approaches such as mass cytometry and spectral cytometry that include simultaneous assessment of 20–50 analytes. Unfortunately, this approach also engenders significant complexity with analytical and interpretational pitfalls. Methods: Here, we demonstrate a complementary approach with restricted-dimensionality to assess cell-type specific intracellular molecular expression levels at exceptional levels of precision. The expression of five analytes was individually assessed in four mononuclear cell-types from peripheral blood. Results: Distinctions in expression …

Our study aims to understand and better elucidate social and clinical characteristics of transmasculine (TM) and transfeminine (TF) individuals and their impact on quality of life and depressive symptoms. In this cross-sectional study, 298 TF and TM individuals on gender-affirming hormone therapy (GAHT) were surveyed about their demographic characteristics …


Beyond The Looking Glass: Dreams And Somnial States And Spaces In Nineteenth-Century British Literature, Anne N. Nagel Apr 2024

Beyond The Looking Glass: Dreams And Somnial States And Spaces In Nineteenth-Century British Literature, Anne N. Nagel

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Poised between a waning magico-theological tradition of symbolic dream interpretation and the rising influence of scientific dream theories, which equated dreaming with disorder, the dream occupied a unique space in nineteenth-century Great Britain. Dreams were coming untethered from signification, as natural philosophers deemed their content indecipherable and chaotic. Yet vestiges of early modern beliefs could still lend supernatural power and polyphony to dreams.

This was not simply a matter of making a binary choice between two ways of thinking about dreams but instead a site of collisions and coalescences. I contend that the ways in which dreams were conceptualized in …

Intercellular Communication Via Gap Junctions Influences Stem Cell Therapy, Madison Bohatuk, Megan Bohatuk, Lauren Harmon Apr 2024

Intercellular Communication Via Gap Junctions Influences Stem Cell Therapy, Madison Bohatuk, Megan Bohatuk, Lauren Harmon

Honors Projects

Adult somatic stem cell therapy can be beneficial for cardiac muscle recovery following injury to the heart. However, a common problem with various approaches to this therapy has been the early (< 24 hrs) loss of a large percentage of the implanted stem cells, which decreases their therapeutic potential. We have demonstrated that cell coupling occurs between stem and cardiac cells through Cx43 gap junctions.Thus, we hypothesize that gap junctions may act as conduits for molecular apoptotic signals from injured cardiac muscle cells that impair the viability of implanted stem cells ('Bystander Effect' ). In our initial experiments, we will use a fluorescently-tagged RNAi control oligo to transfect mouse bone marrow-derived mesenchymal stem cells (mBM- MSCs) and measure transfection efficiency with fluorescence-activated cell sorting (FACS). Additional studies will determine mBM-MSC Cx43 protein expression and the level of Cx43 protein down-regulation in the mBM-MSCs.

Human cytomegalovirus (HCMV) is a leading infectious cause of birth defects and the most common opportunistic infection that causes life-threatening diseases post-transplantation; however, an effective vaccine remains elusive. V160 is a live-attenuated replication defective HCMV vaccine that showed a 42.4% efficacy against primary HCMV infection among seronegative women in a phase 2b clinical trial. Here, we integrated the multicolor flow cytometry, longitudinal T cell receptor (TCR) sequencing, and single-cell RNA/TCR sequencing approaches to characterize the magnitude, phenotype, and functional quality of human T cell responses to V160. We demonstrated that V160 de novo induces IE-1 and pp65 specific durable polyfunctional …


The Bloodless Period: A Transfeminine Experience, Rin Nguyen Apr 2024

The Bloodless Period: A Transfeminine Experience, Rin Nguyen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

There is limited research exploring menstruation in transgender and gender diverse (TGD) populations, and studies have primarily examined the relationship between menstruation and gender congruence. Findings revealed menstruating TGD people experienced distress related to decreased gender congruence (Eisenberg et al., 2021), and 88% of TGD people expressed interest in menstrual suppression to manage the distress (Schwartz et al., 2022). By contrast, Lowik (2020) highlighted a transfeminine person who wished to menstruate to achieve womanhood and commented on the “bloodless period” (i.e., menstrual-like symptoms in the absence of bleeding) upon receiving gender-affirming hormone therapy. To the author’s knowledge, there is no …

Novel Insights Into The Autoimmune Mechanisms In Coxsackievirus B Infections And Their Prevention By Vaccination, Mahima Theresa Rasquinha Apr 2024

Novel Insights Into The Autoimmune Mechanisms In Coxsackievirus B Infections And Their Prevention By Vaccination, Mahima Theresa Rasquinha

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Coxsackievirus Bs (CVBs) are RNA viruses of the genus Enterovirus belonging to the Picornaviridae family. CVBs commonly infect humans, and multiple CVB types can induce similar diseases such as myocarditis, pancreatitis, and type 1 diabetes (T1D). Although CVB infections can lead to the generation of autoantibodies, their role in disease is poorly defined, and vaccines are not available to prevent or minimize these infections. To fill these gaps, we first analyzed the autoantibody repertoire in mice infected with CVB3 by Phage ImmunoPrecipitation Sequencing (PhIP-Seq) and identified autoantibodies for several novel antigens not previously reported. The data were validated using enzyme-linked …
