Role of DEFECTIVE IN SYSTEMIC DEFENSE INDUCED BY ABIETANE DITERPENOID 1 (DSA1), a Putative O-Fucosyltransferase, in Plant Systemic Acquired Resistance (SAR)

Description: Dehydroabietinal (DA), an abietane diterpenoid, was previously demonstrated to be a potent activator of systemic acquired resistance (SAR). DA also promotes flowering time in Arabidopsis thaliana by repressing expression of the flowering repressor FLOWERING LOCUS C (FLC) while simultaneously upregulating expression of FLOWERING LOCUS D (FLD), FLOWERING LOCUS VE (FVE) and RELATIVE OF EARLY FLOWERING 6 (REF6), a set of flowering time promoters. To further understand the mechanism underlying signa… more

Manipulation of Lipid Droplet Biogenesis for Enhanced Lipid Storage in Arabidopsis thaliana and Nicotiana benthamiana

Description: In this study, I examined the use of mouse (Mus musculus) Fat Specific Protein 27 (FSP27) ectopically expressed in Arabidopsis thaliana and Nicotiana benthamiana as a means to increase lipid droplet (LD) presence in plant tissues. In mammalian cells, this protein induces cytoplasmic LD clustering and fusion and helps prevent breakdown of LDs contributing to the large, single LD that dominates adipocytes. When expressed in Arabidopsis thaliana and Nicotiana benthamiana, FSP27 retained its functi… more

Linkage of the Nitrilase-Encoding Nit1C Gene Cluster to Cyanotrophy in Acinetobacter haemolyticus

Description: The Nit1C cluster is a conserved gene cluster of seven genes that confers bacterial growth on cyanide as the sole nitrogen source. Bacteria with this ability are referred to as cyanotrophs. To date, the linkage between Nit1C and cyanotrophy has only been demonstrated for environmental isolates but the cluster also exists in certain medically related bacteria. In this study, a nosocomial isolate, Acinetobacter haemolyticus ATCC 19194, carrying Nit1C also displayed the ability to grow on cyanide.… more

Computational Modeling of Cancer-Related Mutations in DNA Repair Enzymes Using Molecular Dynamics and Quantum Mechanics/Molecular Mechanics

Description: This dissertation details the use of computational methods to understand the effect that cancer-related mutations have on proteins that complex with nucleic acids. Firstly, we perform molecular dynamics (MD) simulations of various mutations in DNA polymerase κ (pol κ). Through an experimental collaboration, we classify the mutations as more or less active than the wild type complex, depending upon the incoming nucleotide triphosphate. From these classifications we use quantum mechanics/molecula… more

A Study of Anomalous Conduction in n-Type Amorphous Silicon and Correlations in Conductivity and Noise in Gold Nanoparticle-Ligand Arrays

Description: This work explores two very different structural systems: n-type hydrogenated amorphous silicon (a-Si:H) and gold nanoparticles (AuNPs) suspended in a matrix of organic ligands. For a-Si:H, examination of the gas-phase concentration of dopant (1-6% PH3/SiH4) and argon diluent effects includes the temperature dependent conductivity, low-frequency electronic noise, and Raman spectroscopy to examine structure. It is found that a-Si:H samples grown with high dopant concentration or with argon dilut… more

Medicago truncatula NPF1.7: Structure-Function Assessment and Potential as a Phytohormone Transporter

Description: In Medicago truncatula, the MtNPF1.7 transporter has been shown to be essential for root morphology and nodulation development. The allelic MtNPF1.7 mutants, Mtnip-1 (A497V), Mtnip-3 (E171K), and Mtlatd (W341STOP), show altered lateral root growth and compromised legume-rhizobium symbiosis. To assess the role of a series of distinct amino acids in the transporter's function, in silico structural predictions were combined with in planta complementation of the severely defective Mtnip-1 mutant pl… more

Regulation of Receptors in Neuronal Cilia with Development, Seizures, and Knockouts: Implications for Excitability

Description: Neurons commonly have a primary cilium, which is a non-motile organelle extending from the centrosome into the extracellular space. In most brain regions, neuronal cilia are enriched in either somatostatin receptor type 3 (SstR3) or melanin concentrating hormone receptor type 1 (MCHR1), or both. The present immunohistochemical study provides novel evidence that primary cilia regulate neuronal excitability via G-protein coupled receptors (GPCRs), and that their identity is governed by brain re… more

Investigating the Mechanisms involved in Traffic-Generated Air Pollution: Mediated Disruption of the Blood-Brain Barrier in a Wild Type Mouse Model using a Pharmaceutical Intervention Approach

Description: This study investigated whether oxLDL and/or angiotensin (Ang) II signaling pathways mediate traffic-generated air pollution- exposure induced alterations in blood-brain barrier (BBB) integrity and permeability in a healthy wild type (C57Bl/6) mouse model; additionally, whether these outcomes are exacerbated by a high fat-diet investigated. An environmentally relevant concentration of a mixture of vehicle engine exhaust (MVE) was used. To investigate the hypotheses, 12 wk old male C57Bl/6 mice… more

The Question Concerning Endocrinology: Judith Butler's Gender Theory and Transgender Hormone Therapy

Description: For such a vexing topic as gender identity, this dissertation asks a rather straightforward question: If gender identity is—as Judith Butler has asserted—socially constructed and discursively mediated, then why does transgender hormone therapy (THT) work? This is the question concerning endocrinology that I ask Butler, and their answer is, if requiring of delicate assessment and interpretation, clear: it doesn't. Butler's work reveals an admonishing view that the efficacity of THT is due to pla… more

The Amalgamation of Western and Eastern Influences in Julius Schloss's "First Chinese Rhapsody"

Description: The dissertation seeks to rediscover Julius Schloss, a German Jewish composer victimized by the Nazis. Except for the promising start of his career in his early years, Schloss suffered a hard life as an exiled refugee. However, his unusual experiences inspired him to compose two Chinese Rhapsodies during his last years of exile in Shanghai, in which he synthesized Western composition techniques and Chinese folk materials, amalgamating influences from both Western and Eastern music cultures.

Sacred Sound at the Symphony: A Conductor's Guide to Faith Traditions in Choral-Orchestral Repertoire

Description: Since most historical composers of Western art music were European Christians (or resided in areas that were primarily populated by Christians), a vast majority of the sacred choral-orchestral repertoire is based on major figures and themes from the most prominent denominations, including Catholicism, Lutheranism, and Anglicanism. As a corollary this is also the case for analytical, pedagogical, and exegetical literature related to the topic. However, in the late nineteenth century some compo… more
