Sexual Scripts In Conflict: Does Religiosity Moderate The Relationship Between Pornography Use And Permissive Sexuality?, Alex D. Castaneda

Doctoral Dissertations and Projects

The sexual script acquisition, activation, and application model (3AM) posits that viewing pornography leads to the internalization of the scripts implicitly and explicitly depicted. Recent research indicates that pornography viewing is associated with more permissive sexuality. Religious individuals, especially conservative Christians, report greater distress from their pornography use, and research has investigated the role of religiosity in pornography-related outcomes. Religiosity has been shown to protect against pornography exposure and buffer against the internalization of the pornographic script. Sexual script theory posits that individuals with existing scripts that are more deeply held will be less susceptible to new, contradictory scripts. This …

Machine Learning-Based Determination Of Sex-Related Bladder Cancer Biomarkers, Joseph Pizzi

Theses

Bladder cancer exhibits sex-specific behavior, occurring more frequently in males but progressing to advanced stages more commonly in females. The activation of sex hormone receptors may explain these differences, but the exact genetic drivers remain poorly understood. Furthermore, current bladder cancer biomarkers have inconsistent sensitivities and specificities in practice, making early diagnosis a challenge. This study approaches bladder cancer biomarker discovery through machine learning techniques on gender and disease-stratified RNA-seq data. Training sets limited to differentially expressed genes were subjected to four different feature selection methods: differential gene expression analysis adjusted p-value, recursive feature elimination with support vector machine, logistic …

Faculty, Staff and Students Publications

Transforming growth factor β (TGFβ) signaling pathways are integral for a plethora of biological processes. SMAD2 and SMAD3 are the principal transcriptional effectors of TGFβ superfamily ligands, yet quantitative, genome-wide mapping of their DNA-associated complexes under physiological contexts has remained limited due to the lack of specific, robust models. Here, we generated two versatile epitope-tagged mouse models in which endogenous SMAD2 and SMAD3 proteins are globally tagged with hemagglutinin (HA) and podoplanin (PA) sequences, respectively, enabling high-fidelity profiling of SMAD2 and SMAD3 binding across tissues. To demonstrate the broad application of our models, we exemplified the usage of our lines …

Developing Endpoints For The Cardiac Burden In Myotonic Dystrophy Type 1: A Workshop Report, Julia M Hartman, Samuel Carrell, William J Groh, Thomas A Cooper, Jordana Kron, Greg Hundley, Jennifer Jordan, Amy Ladd, Man Hung, Nicholas E Johnson

Faculty, Staff and Students Publications

Cardiac disease is a well-established manifestation of myotonic dystrophy type 1 (DM1), characterized by progressive cardiac conduction slowing with increased risk of atrial and ventricular arrhythmias, heart block, and sudden cardiac death. Multiple disease modifying therapies are in clinical trials for DM1 and show promise in improving skeletal muscle weakness and myotonia. Testing the effects of these medicines, or others, in the heart is of critical importance, but requires identification of endpoints of cardiac function that accurately reflect the state of DM1 cardiac disease. To better define cardiac endpoints, the Myotonic Dystrophy Clinical Research Network (DMCRN) and the Myotonic Dystrophy …

Structure-Preserving Multivariate Hypothesis Testing For Mass Spectrometry Imaging And Single-Cell Data, Keziah E Liebenberg, Erin Craig, Robert Tibshirani, Livia S Eberlin

Faculty, Staff and Students Publications

Motivation: Mass spectrometry imaging (MSI) and single-cell RNA sequencing (scRNA-seq) offer high-resolution views into tissue and cellular heterogeneity. However, conventional statistical analyses often treat sub-measurements (pixels or cells) as independent, ignoring their nested origin from individual samples. This assumption inflates the effective sample size, increases false discoveries, and undermines biological interpretation. Pixel- or cell-level averaging avoids this but sacrifices spatial or cellular resolution.

Results: We evaluated block-SAM on both simulated and real-world datasets. In DESI-MSI data from kidney, lung, and ovarian tumors, block-SAM consistently identified fewer-but more reliable-differential features compared to traditional-SAM. For example, in the kidney dataset, traditional-SAM identified …

2020-Current year OA Pubs

Concentration-based fluid biomarkers represent an informative and cost-effective way to detect and monitor Alzheimer's disease (AD) pathology. However, non-AD-related interindividual variation in biofluids can also affect biomarker concentrations. Here, we investigated whether normalization of CSF and plasma biomarkers to reference proteins, such as amyloid-β40 (Aβ40) and non-phosphorylated mid-region tau (np-tau), improves their robustness and reliability of representing AD pathology load. Using the Swedish BioFINDER-2 cohort [n = 1702, 50.7% male, mean (standard deviation) age 68.4 (12.2) years], we compared the associations between tau/Aβ-PET load and fluid biomarkers alone versus biomarkers in a ratio with a reference protein (Aβ40 or np-tau) …
