Patterns Of Molecular Evolution Driving Reproductive And Genomic Processes In Sauropsids, Taylor Green

Theses and Dissertations

Sexual reproduction is an important driver of genetic diversity and speciation through such forces as selection, mutation, and drift. Sauropsids are an appropriate clade to study shared molecular drivers of sexual and genomic evolution due to their genome architecture, sex determination mechanism (SDM) plasticity, and large syntenous genomic regions. Using comparative phylogenetic methods, I identify predictable patterns of selection in meiotic recombination genes and clade-specific drivers of recombination rate evolution. Then, leveraging whole genome sequencing, I demonstrate that American alligator genomes are characterized by an ancient loss of genetic diversity driven by drift and historic inbreeding. I also generate a …

Mllt1 Is Required To Maintain B-Lymphopoiesis, Janani Prakash

Dissertations

MLLT1 (also named ENL) is an epigenetic reader protein that binds to crotonylated or acetylated lysine residues of histone 3 through its N-terminal YEATS domain. Positive and negative regulatory complexes compete for binding to C-terminal MLLT1, and promote transcription elongation (SEC, Super elongation complex; DOT1L) or transcriptional repression (PRC1, Polycomb repressive complex 1). MLLT1 was initially identified as a chromosomal translocation partner to MLL(KMT2A) in a subset of MLL-rearranged leukemias. MLL-ENL fusion protein causes both lymphoid (predominantly B-ALL) and mixed lineage leukemias. MLLT1 has been implicated in leukemic stem cell survival in MLL-rearranged cell lines but its role in normal …

Frye Is So Last Century: It’S Time For Washington To Get With The Times, Darian Mullen

Seattle Journal of Technology, Environmental, & Innovation Law

This paper argues that Washington State should finally abandon the

Frye test for expert witnesses and adopt the Daubert test used by federal

courts and most states. It begins with a discussion of the background of

expert witnesses in the U.S. court system and its evolution through Frye.

Then, it looks at the increase in drunk driving in Washington State as a

case study for how the public depends on quality science to protect

individuals and punish wrongdoers. Through the case study, it is

apparent that Frye is an unworkable standard that should be superseded

by Daubert.

The Extraction And Chemical Characterization Of The Avian Pigments Turacin And Turacoverdin, Sarah R. Bekkali

Honors Scholar Theses

Bird coloration is a trait that extends beyond mere aesthetics as it has an extensive range of biological significance. Plumage patterns and hues can influence camouflage, mate choice, social dominance, and physiological performance. Bird fitness, their ability to survive and reproduce, is greatly dependent on color. Melanins, carotenoids, and pterins are well-studied pigment systems that are commonly found across many avian species’. Alternatively, porphyrin-based pigments are rare and less-studied as they only found in turacos a sub-Saharan African bird belonging to the family Musophagidae. This thesis focuses on two pigments of interest: turacin, the deep crimson-red pigment found in …

Proximal Stress And Gender Identity: The Role Of Internalized Transphobia In Future Expectations, Maribelle Almonacy

Student Theses and Dissertations

Transgender and non-conforming (TGNC) youth and young adults are more likely to experience symptoms of posttraumatic stress due to identity-specific abuse. Studies on the impact of trauma on negative expectations in high-risk youth show a high association between pessimism, nihilism, and instability. Internalized transphobia, similarly, is correlated with negative mental health outcomes, such as depression and anxiety, and the internalization of social messages and discrimination. These studies are not specific to the experiences of gender minorities and do not explore the intersections of internalized stressors or trauma in young adults. To address this gap in literature, this study sought to …

Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones

Seton Hall University Dissertations and Theses (ETDs)

This qualitative study examined how insured non-English- and English-speaking Hispanic adults perceive the role of health insurance in the management of chronic disease. Chronic conditions remain a leading cause of morbidity in the United States, and although prior research suggests that insurance coverage improves access to care, it does not always enhance how individuals understand or utilize support for chronic disease management. Limited research has explored how individuals with chronic conditions interpret the role of insurance in their daily self-management practices, particularly among Hispanic populations. Guided by Andersen’s Behavioral Model of Health Services Use, this study explored how contextual, enabling, …
