Metabolic Modeling Of Cystic Fibrosis Airway Microbiota From Patient Samples, Arsh Vyas
Metabolic Modeling Of Cystic Fibrosis Airway Microbiota From Patient Samples, Arsh Vyas
Masters Theses
Cystic Fibrosis (CF) is a genetic disorder, found with higher prevalence in the Caucasian population, affecting > 30,000 individuals in the United States and > 70,000 worldwide. Due to the astoundingly high rate of mortality among CF patients being attributed to respiratory failure brought on by chronic bacterial infections and subsequent airway inflammation, there has been a lot of focus on systematically analyzing CF lung airway communities. While it is observed traditionally that Pseudomonas aeruginosa is the most threatening and persistent CF colonizer due to high antibiotic resistance, recent studies have elicited the roles of other pathogens and it has been widely …
Structure-Function Studies Of The Trypanosome Mitochondrial Replication Protein Polib, Raveen Armstrong
Structure-Function Studies Of The Trypanosome Mitochondrial Replication Protein Polib, Raveen Armstrong
Masters Theses
Trypanosoma brucei and related protists are distinguished from all other eukaryotes by an unusual mitochondrial genome known as kinetoplast DNA (kDNA) that is a catenated network composed of minicircles and maxicircles. Replication of this single nucleoid involves a release, replicate, and reattach mechanism for the thousands of catenated minicircles and requires at least three DNA polymerase (POLIB, POLIC and POLID) with similarity to E. coli DNA polymerase I. Like other proofreading replicative DNA polymerases, POLIB has both an annotated polymerase domain and an exonuclease domain. Predictive modelling of POLIB indicates that it has the canonical right hand …
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, Dilay Hazal Ayhan
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, Dilay Hazal Ayhan
Doctoral Dissertations
Fusarium oxysporum is a cross-kingdom pathogenic fungus that can cause vascular wilt disease in many economically important plants and local or disseminated infections in humans. Although it lacks a sexual stage in its life cycle, F. oxysporum can adapt to a wide range of hosts because of accessory chromosomes (ACs) which are enriched in host-specific genes and repeat content. This dissertation investigates the mechanisms that drive the adaptive evolution in the cross-kingdom pathogen F. oxysporum using comparative genomics and an experimental evolution approach. The first chapter compares phenotypes and genomes of a plant pathogenic isolate F. oxysporum f. sp. lycopersici …
Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Masters Theses
Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …

A large proportion of the Asian population fulfills their energy requirements from wheat (Triticum aestivum L.). Wheat quality and yield are critically affected by the terminal heat stress across the globe. It affects approximately 40% of the wheat-cultivating regions of the world. Therefore, there is a critical need to develop improved terminal heat-tolerant wheat varieties. Marker-assisted breeding with genic simple sequence repeats (SSR) markers have been used for developing terminal heat-tolerant wheat varieties; however, only few studies involved the use of microRNA (miRNA)-based SSR markers (miRNASSRs) in wheat, which were found as key players in various abiotic stresses. In the …

Background: Transcriptomic data has demonstrated utility to advance the study of physiological diversity and organisms' responses to environmental stressors. However, a lack of genomic resources and challenges associated with collecting high-quality RNA can limit its application for many wild populations. Minimally invasive blood sampling combined with de novo transcriptomic approaches has great potential to alleviate these barriers. Here, we advance these goals for marine turtles by generating high quality de novo blood transcriptome assemblies to characterize functional diversity and compare global transcriptional profiles between tissues, species, and foraging aggregations.ResultsWe generated high quality blood transcriptome assemblies for hawksbill (Eretmochelys imbricata), loggerhead …

Navigating The U.S. Health Insurance Landscape For Children With Rare Diseases: A Qualitative Study Of Parents' Experiences, Tai L. S. Pasquini, Sarah L. Goff, Jennifer M. Whitehill
Health Promotion and Policy Faculty Publication Series
Parents of children with rare diseases often face uncertainty about diagnosis, treatment, and costs associated with healthcare for their child. Health insurance status impacts each of these areas, but no U.S. study has explored parents' perceptions of the health insurance impacts on their child's care. This study aimed to qualitatively explore how these parents navigate the complex health insurance system for their children and their experiences in doing so. Methods Semi-structured interviews were conducted with parents of children with metachromatic leukodystrophy (MLD) and spinal muscular atrophy (SMA), chosen for specific disease characteristics and orphan drug status. Participants were recruited via …
