Honors Theses and Capstones

Nearly one out of six deaths in 2020, around ten million people, were caused by cancer, making it a leading cause of death worldwide (WHO, 2022). This major public health issue, in addition to the rise of multidrug-resistant (MDR) pathogens, provides a high demand for the discovery of new pharmaceutical drugs to be used clinically to treat these conditions. The Streptomyces genus accounts to produce 39% of all microbial metabolites currently approved for human health, indicating its potential as an important species to study for antimicrobial and anticancer agents. The long linear genome of Streptomyces contains specialized sequences known as …

Effects Of Aging On The Reproductive Success Of Female Saltmarsh Sparrows (Ammospiza Caudacutus) In Maine And New Hampshire, Isabella Rose Collamati

Honors Theses and Capstones

The saltmarsh sparrow (Ammospiza caudacutus) is a ground-nesting specialist in coastal salt marshes of the Northeast. Rising sea-levels increase the loss of offspring due to tidal flooding, reducing nest success and resulting in a sharp population decline. In other avian species, age has been shown to affect nest success through altering fertility, behavior, and the number of young produced, favoring older individuals. I investigated age effects on nest success of female saltmarsh sparrows using nest monitoring data collected at four sites of a long-term demographic monitoring project: Chapman's Landing (Stratham, NH), Eldridge Marsh (Wells, ME), Popham Beach (Phippsburg, …

Odd Bedfellows & Marriage Of Necessity: Public Health And Politics In American Federalism, Gabriella Victoria Chianese

Honors Theses and Capstones

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, while the public disagrees over mask mandates, required vaccinations, and social distancing, it seems like one common sentiment exists – a distaste for the odd bedfellows of politics and public health. There are those who cry for the compartmentalization of the science of public health and the art of politics to rectify this situation. In the wake of so much confusion and chaos, it is not unjustified to demand the depoliticization of public health; however, this response is unrealistic given the modern political climate, demonstrates a narrow understanding of the …

Investigating Bzip Recognition Of Dna Sequences Through A Knob-Socket Perspective, Aaron Tran

University of the Pacific Theses and Dissertations

To investigate whether higher order packing interactions confer protein-DNA specificity, a modified Knob-Socket (KS) model was used to analyze the interface of bZIP-DNA crystal structures. The KS analysis identified a nine-residue quadripartite recognition core consisting of four contiguous KS pockets P1, P2, N3, and N4 that each pack one of the four DNA half-site bases in the target sequence. Only one base per base pair packs, and these interactions are split across the DNA strands: the first two positive strand positions 1p and 2p pack into P1 and P2 while the last two negative strand positions 3n and 4n pack …

A Dnak Chaperone System Connects Type Iv Pilus Activity To Polysaccharide Secretion In The Cyanobacterium Nostoc Punctiforme, Heather J. Mcdonald

University of the Pacific Theses and Dissertations

Type IV pili (T4P) systems are widely utilized among bacteria to power and direct surface motility. The production and secretion of a viscous polysaccharide to provide friction and resistance to the extended pilus structure is seen in several species of cyanobacteria including Nostoc punctiforme. The complex coregulation of polysaccharide secretion and T4P motor activity is not fully understood, although studies indicate a consistent relationship between functional motility and intact pathways of polysaccharide secretion and pilus extension in cyanobacteria. Using a combination of protein-protein interaction analysis, cytological studies, and comparative genomics this study proposes a theoretical mechanism for T4P motor influenced …

Investigating Optimal Lipid:Protein Profiles For Infant Milk Formula, Valentina Ivanova

Identifying Host-Intrinsic Resistance Mechanisms To Therapeutic Anti-Tumor Antibody, James Edward Glassbrook

Wayne State University Dissertations

The use of monocloncal antibodies (mAbs) directed at tumor-associated antigens (TAA), often termed “targeted immunotherapy” has revolutionized cancer treatment, markedly improving patient outcomes. As a prime example, the mAb trastuzumab targets human epidermal growth factor 2 (HER2). Like many targeted immunotherapies, only a subset of patients with HER2+ cancer exhibit long-term benefit from trastuzumab. In addition to tumor-intrinsic factors, such as HER2 heterogeneity, we hypothesize that host genetics may influence subsequent immune activation after treatment. To model this interaction, we utilized the genetically heterogeneous Diversity Outbred (DO) mouse model in an F1 cross with BALB/c (producing DOCF1 mice). This cohort …

Using Self-Efficacy Theory To Design Arduino Instruction For Novices: A Replication Study, Donald M. Johnson, Michael Pate, Chris Estepp, George W. Wardlow

Agricultural Education, Communications and Technology Faculty Publications and Presentations

A replication study was conducted to determine the effectiveness of an instructional treatment based on self-efficacy theory when used with novice Arduino microcontroller users. Students (n = 32) in an introductory university agricultural systems technology course participated in a lesson on Arduino microcontrollers, circuit breadboarding, and Arduino programming which included four hands-on practice tasks, designed to provide students with positive mastery, vicarious and social persuasion experiences. Next, students completed a laboratory activity and were provided additional opportunities for mastery, vicarious, and social persuasion experiences. The one-group pretest-posttest design indicated the instructional treatment had significant (p < .001) and large effects in increasing students’ interest in Arduino, breadboarding self-efficacy, programming self-efficacy, and Arduino knowledge. These findings were consistent with the original study and provided additional evidence for self-efficacy theory as an effective model for developing instruction for novice Arduino users. Students’ written comments provided additional insight concerning the instructional treatment.

Burnout In Sport Specializers Versus Samplers: An Evidence-To-Practice Review, Katherine Godfrey, Justin Disanti, Tamara Valovich Mcleod

Clinical Practice in Athletic Training

The prevalence of sport specialization is a common concern in contemporary youth sports and has been linked to potential negative physical and psychological effects for developing athletes. While the evidence regarding negative physical effects, such as overuse injury, are consistent in the literature, the psychosocial outcomes are unclear due to the lack of published studies on the topic. Specialization is thought to lead to added stress, which may affect an athlete’s mental health, whereas athletes who sample multiple sports are believed to have a healthier psychosocial experience. Burnout is characterized as physical and emotional exhaustion, sport devaluation and a reduced …

Review Of Diagnostic Accuracy Of The Ottawa Knee Rules In Adult Acute Knee Injuries, Sean L. Glover, Amy M. Loveless, Sara A. Posson, Zachary K. Winkelmann

Clinical Practice in Athletic Training

Acute knee injuries are commonly found in athletic populations. The wide range of knee injuries can present a challenge deciding which injuries require imaging. Currently, radiography is considered the gold standard of imaging for knee fractures. However, imaging is often costly not only for the patient, but also for the healthcare system. Since imaging is expensive, it is critical that clinicians decipher which patients require such testing. The Ottawa Knee Rules (OKR) is a predictor tool created by Stiell et al in 1995 to help clinicians accurately distinguish potential knee fractures from non-fractures for imaging purposes. The OKR guidelines state …
