The Influence Of Drd2 Polymorphism Exon 8 C/T (Rs6276) On Manifestations Of Delirium Tremens & Alcohol Withdrawal Seizures, Naomi Schneider
The Influence Of Drd2 Polymorphism Exon 8 C/T (Rs6276) On Manifestations Of Delirium Tremens & Alcohol Withdrawal Seizures, Naomi Schneider
Honors Theses and Capstones
This study explores the correlation between the DRD2 Polymorphism exon 8 C/T (rs6276) and manifestations of delirium tremens (DT). DT is a condition that is clinically diagnosed utilizing two characteristic symptom manifestations: the presence of delirium and severe alcohol withdrawal. It is not entirely understood why DT can occur in some patients, but evidence has suggested that genetic predisposition can play a role. Utilizing the National Institutes of Health (NIH) All of Us Research database and performing a secondary analysis of existing genomic data, this candidate gene association study aims to determine the genotype frequencies within three cohorts: a healthy …
Impact Of Hdac Inhibitors On The Efficiency Of Cardiomyocyte Differentiation, Lauren Mary Sargent
Impact Of Hdac Inhibitors On The Efficiency Of Cardiomyocyte Differentiation, Lauren Mary Sargent
Honors Theses and Capstones
Heart disease and injury is the leading cause of death worldwide, with much of its severity caused by the low regenerative capacity of cardiomyocytes (CMs). One of the strategies to counteract the poor regeneration of CMs is the production of CMs via differentiating stem cells. However, the low efficiency of obtaining CMs from stem cells is an issue because there are numerous inconsistencies in the process. Histone deacetylase (HDAC) inhibitors have been researched as ways to increase efficiency of CM differentiation by increasing histone acetylation, and thereby allowing differentiation to occur more efficiently. In this study, the HDAC inhibitor, trichostatin …
Investigating The Function Of Protein S-Acyltransferase 2 In Arabidopsis Thaliana Using Crispr Mutants, Nicole Benjamin
Investigating The Function Of Protein S-Acyltransferase 2 In Arabidopsis Thaliana Using Crispr Mutants, Nicole Benjamin
Honors Theses and Capstones
Arabidopsis thaliana contains 24 Protein Acyl Transferases (PATs). These enzymes are responsible for catalyzing the addition of a palmitate to a target substrate (palmitoylation). However, beyond its broad enzymatic function, it is unknown how PATs interact on a cellular level. This research focuses on identifying the function of PAT2. CRISPR-Cas9 was used to create deletion mutations that would result in a non-functional PAT. Two plants homozygous for a pat2 deletion were identified: pat2-5 and pat2-6. Preliminary results suggest that pollen grains in both pat2 mutants are larger in both length and width. Additionally, it appears that mutant pollen tends to …

Spatial And Temporal Variation In Population Genetic Diversity In Seagrasses And The Implications For Resilience, Anna Maria Frouws
Spatial And Temporal Variation In Population Genetic Diversity In Seagrasses And The Implications For Resilience, Anna Maria Frouws
Theses: Doctorates and Masters
Seagrass ecosystems are highly productive and fulfil vital roles in the coastal environment as ecosystem engineers and keystone species. Unfortunately, anthropogenic pressures have resulted in a significant loss of seagrass habitat and associated ecosystem services. The complex and unpredictable nature of these pressures, and their increasing extent and intensity globally, makes resilience-based ecosystem management a valuable approach. Resilience-based management requires knowledge on processes enhancing ecosystem resilience and on actions supporting these processes. Genetic diversity, which is the allelic variation among individuals of a population, has been recognised as one of the pillars of resilient ecosystems. Genetic diversity within a population …

Faculty, Staff and Student Publications
Background/aim: Non-small cell lung cancer (NSCLC) is increasingly detected in early stages and there is interest in improving outcomes with stereotactic body radiotherapy (SBRT). As metformin affects NSCLC signaling pathways, it might alter the metabolism of NSCLC treated with SBRT. This study investigated the long-term outcomes of a phase II clinical trial evaluating metformin in conjunction with SBRT for early-stage NSCLC.
Patients and methods: The trial evaluated patients with American Joint Commission on Cancer (AJCC) 7th edition Stage I-II, cT1-T2N0M0 NSCLC who were randomized 6:1 to receive metformin versus placebo in conjunction with SBRT. The outcomes analyzed included local failure …

Background: Predicting suicide is a pressing issue among older adults; however, predicting its risk is difficult. Capitalizing on the recent development of machine learning, considerable progress has been made in predicting complex behavior such as suicide. As depression remained the strongest risk for suicide, we aimed to apply deep learning algorithms to identify suicidality in a group with late-life depression (LLD).
Methods: We enrolled 83 patients with LLD, 35 of which were non-suicidal and 48 were suicidal, including 26 with only suicidal ideation and 22 with past suicide attempts, for resting-state functional magnetic resonance imaging (MRI). Cross-sample entropy (CSE) analysis …

Meta-Analysis Of The Vmp-Like Sequences Of Lyme Disease Borrelia: Evidence For The Evolution Of An Elaborate Antigenic Variation System, Steven J Norris, Kalvis Brangulis
Meta-Analysis Of The Vmp-Like Sequences Of Lyme Disease Borrelia: Evidence For The Evolution Of An Elaborate Antigenic Variation System, Steven J Norris, Kalvis Brangulis
Faculty, Staff and Student Publications
VMP-like sequence (vls) antigenic variation systems are present in every Lyme disease Borrelia strain with complete genome sequences. The linear plasmid-encoded vls system consists of a single expression site (vlsE) and contiguous array(s) of silent cassettes that have ~90% identity with the central cassette region of the cognate vlsE gene; antigenic variation occurs through random, segmental, and unidirectional recombination of vls silent cassette sequences into the vlsE expression site. Automated annotation programs do not accurately recognize vls silent cassette sequences, so these regions are not correctly annotated in most genomic sequences. In this study, the vls …

Background: Pegvaliase, an enzyme substitution therapy, is a treatment option for phenylketonuria (PKU). Due to the neuropathophysiology and disease burden of PKU, individuals can experience baseline anxiety unrelated to pegvaliase therapy. In addition, there are aspects of pegvaliase therapy that may be anxiety-inducing for those considering or receiving treatment. The aim of this manuscript is to present best practice recommendations for the identification and management of anxiety symptoms that can occur along the pegvaliase journey.
Methods: A modified Delphi approach was used to seek consensus among a multidisciplinary panel of experts. To this end, an in-person meeting was held that …

Exploring The Relative Contribution Of Humans On Genetic Differentiation Among Speyeria Callippe Populations In The California Coast Ranges, Laura K. Heller
University of the Pacific Theses and Dissertations
The distinction between populations due to environmental factors like climate and geography are well-known and expected, therefore it is not illogical to believe more disjunct habitats would also impact genetic structure. Through Restriction Site Associated DNA Sequencing (RADseq) and Mitochondrial DNA (mtDNA) analysis the genetic structure and differentiation (fixation index, Fst) of Speyeria callippe across four regions in California: the North Coast Ranges, Bay Area, Diablo Range, and South Coast Ranges were analyzed. The influence of geographic distance, human population density, and forest cover were explored as factors influencing the genetics of these populations. The combination of mtDNA and RADseq …

Quantitative Shotgun Proteomic Analysis Of Bacteria After Overexpression Of Recombinant Spider Miniature Spidrion, Masp1, Kathryn P. Randene
University of the Pacific Theses and Dissertations
Spider silk has extraordinary mechanical properties, displaying high tensile strength, elasticity, and toughness. Given the high performance of natural fibers, one of the long-term goals of the silk community is to manufacture large-scale synthetic spider silk. This process requires vast quantities of recombinant proteins for wet-spinning applications. Attempts to synthesize large amounts of native size recombinant spidroins in diverse cell types have been unsuccessful. In these studies, we design and express recombinant miniature black widow (Latrodectus hesperus) MaSp1 spidroins in bacteria that incorporate the NTD and CTD, along with varying numbers of codon-optimized internal block repeats. Following spidroin overexpression, we …
Effects Of Glyphosate-Based Herbicide Exposure On Life History, Stress Tolerance, And Microbiome—From Plasticity To Evolution, Jacob R. Whitlock
Effects Of Glyphosate-Based Herbicide Exposure On Life History, Stress Tolerance, And Microbiome—From Plasticity To Evolution, Jacob R. Whitlock
University of the Pacific Theses and Dissertations
Glyphosate (GLY) is the most used pesticide worldwide, and GLY-based herbicides (GBHs) can affect animals’ microbiomes and, in turn, their physiology and morphology. Environmental stressors can be mitigated by flexibility in life-history strategies, which can also dictate animal physiology and morphology. However, we lack an understanding of how GBH influences life-history strategies and stress tolerance, in addition to its effects across generations. Thus, I exposed the variable field cricket, Gryllus lineaticeps, to GBH within- and across-generations to examine the role of GBH in developmental plasticity and evolution. Specifically, I measured its effects on life-history traits (e.g., developmental duration and a …
Effects Of Fetal Bovine Serum On The Proteome And Secretome Of Pichia Pastoris, Kenneth L. Nguyen
Effects Of Fetal Bovine Serum On The Proteome And Secretome Of Pichia Pastoris, Kenneth L. Nguyen
University of the Pacific Theses and Dissertations
Komagataella pastoris, formerly known as Pichia pastoris, and hereafter referred to as Pichia, is a methylotrophic yeast widely employed as a recombinant protein factory for biotechnical and industrial purposes. P. pastoris boasts the ability to thrive at high cell densities, executes numerous post-translational modifications, and exhibits minimal secretion of endogenous proteins, thus greatly facilitating the expression and purification of recombinant proteins. Despite these advantages, Pichia still presents certain challenges as an expression system. Occasionally, recombinant proteins are retained within the cell and subject to degradation. Furthermore, Pichia falls short in matching the production capabilities of more widely used systems like …
The Role Of The Unfolded Protein Response In Fatty Liver Disease, Anusha L. Murshed
The Role Of The Unfolded Protein Response In Fatty Liver Disease, Anusha L. Murshed
University of the Pacific Theses and Dissertations
The unfolded protein response (UPR) is composed of three highly conserved pathways (ATF6, IRE1, PERK). Cellular stressors induce protein misfolding and aggregation in the endoplasmic reticulum (ER). This signaling pathway maintains protein homeostasis when there is stress in the ER. When the UPR is activated, the eukaryotic initiation factor 2 alpha (eIF2α) becomes phosphorylated, which inhibits global mRNA translation. If ER stress remains chronically unmitigated, the UPR induces apoptosis. GADD34 and CReP shift in expression when the UPR is activated and work as phosphatases and dephosphorylate eIF2α in a feedback loop, allowing protein synthesis to resume. Several human diseases, including …
Softening And Cross-Susceptibility: Exposure To Heat And Desiccation Reduces Future Stress Tolerance In An Insect, Lauren Harter
Softening And Cross-Susceptibility: Exposure To Heat And Desiccation Reduces Future Stress Tolerance In An Insect, Lauren Harter
University of the Pacific Theses and Dissertations
The frequency and duration of environmental stressors, such as heat waves and drought, will continue to grow due to ongoing climate change, thereby increasing the likelihood that organisms will experience stressors consecutively. Exposure to one stressor can improve or impair future tolerance to the same stressor (i.e., hardening or softening, respectively), or enhance or reduce future tolerance to a different stressor (i.e., cross-protection or cross-susceptibility, respectively). Understanding whether stress improves or impairs animals’ abilities to withstand future stressors is critical for determining the physiological sensitivity of animals to ongoing climate change. Here, I evaluated the responses to consecutive heat and …
Plasticity In Response To Temperature Magnitude And Variation---From Life History To Thermal Tolerance And Coloration, Austin Rex Hoffman
Plasticity In Response To Temperature Magnitude And Variation---From Life History To Thermal Tolerance And Coloration, Austin Rex Hoffman
University of the Pacific Theses and Dissertations
Warming associated with climate change has many direct and downstream effects on animals. For example, warmer developmental temperatures can improve heat tolerance and reduce insect melanization, which is related to coloration, thermoregulation, immunity, desiccation resistance, and potentially life-history traits, such as investment into reproduction and dispersal. Increased temperature variation is also a feature of climate change, and it may have a larger impact on animals than warming. However, I lack insight into the combined effects of temperature magnitude and variability on important traits of life history, thermal tolerance, and coloration. Thus, I integrated temperature variation into thermal performance using a …
Novel Regulators Of Small G Proteins In The Pancreatic Beta Cell, Noah Gleason
Novel Regulators Of Small G Proteins In The Pancreatic Beta Cell, Noah Gleason
Wayne State University Dissertations
Regulation of small GTPases within the pancreatic beta cell is a highly complex and coordinated sequence of protein interactions and post translational modifications. Various families participate in the physiological secretion of insulin in roles ranging from cytoskeletal reorganization to secretory vesicle priming and docking. However the regulatory partners of GTPase function, while studied broadly, lack vital information relating to smgGDS, a protein chaperone of small GTPases to and from the prenylation machinery, and RhoGDI function. Herein these studies are aimed to further our understanding of GTPase regulation and alterations that occur during metabolic stress (glucotoxicity) and related beta cell dysfunction.Data …

Carotenoids have been widely studied for their high dietary, antioxidant, and vision protection roles in the human body. Blood contains all major dietary carotenoids and hence presents as a suitable and efficient substrate for the estimation of dietary carotenoids in vivo. Following the 18-month supplementation of open angle glaucoma patients with macula pigment carotenoids (Lutein, Zeaxanthin and Meso-Zeaxanthin) in the European Nutrition in Glaucoma Management (ENIGMA) trial, Raman spectroscopic analysis of the pre-supplementation baseline and 18-month supplemented blood serum carotenoids from participants was carried out, to investigate the systemic impact of supplementation in the blood and explore a more direct …

School of Earth, Environmental, & Marine Sciences Faculty Publications
Transboundary fishery management represents a significant governance challenge that requires ongoing inter-organizational communication, collaboration, and collective action to ensure sustainability. Previous research suggests that different dimensions of perceived risk, trust, and control interact in complex ways to affect inter-organizational collaborative performance, providing an administrative ‘architecture’ that enables partners to share resources, engage in teamwork, resolve conflict, and coordinate tasks and responsibilities while also allaying their concerns about the alliance. However, the extent to which different control mechanisms influence trust and mitigate the perceived risks of collaboration between the diverse organizations involved in transboundary fisheries management remains unclear. This paper presents …

The author estimates the momentum and kinetic energy of the bird prior to hitting the window, as well as the force, pressure, and wingspan of the bird during impact. The author assumes an inelastic collision between the bird and the window, and provides calculations and explanations for their estimations. The article concludes with the author's observation that the estimated wingspan aligns with that of an adult pigeon.
