Lactobacillus Metabolite-Mediated Induction Of Bacteriophage, Taylor Miller-Ensminger

Master's Theses

Once considered sterile in the absence of an infection, the female urinary tract is home to a diverse community (microbiota) of bacterial species and bacteriophage (phage), viruses that infect bacteria A dominant member of the female urinary microbiota is the bacterial genus Lactobacillus. Several Lactobacillus species are even associated with urinary health. Phage infectious of bacteria in the urinary tract tend to replicate through one of two life cycles: the lytic (active) life cycle or the lysogenic (dormant) life cycle. Temperate phage can switch from the lysogenic life cycle to the lytic life cycle in the presence of an environmental …

The Effect Of Gonadal Steroids Following Repeat Mild Traumatic Brain Injury On Anxiety-Like Behaviors In Rats, Trevor Nykamp

Master's Theses

Traumatic brain injury (TBI) affects millions of people in the U.S. each year. This thesis worked to address anxiety, a common emotional symptom following TBI, by utilizing a five-hit repeat mild TBI (rmTBI) experimental model. First, changes in gonadal status following injury and the severity of anxiety symptoms experienced were investigated. Our data revealed that suppressed testosterone levels following rmTBI resulted in significantly more anxiety-like behaviors across several observational variables. Even more, some of these behaviors were reduced by providing testosterone supplementation immediately following injury.Another goal of this work was to investigate the role of mitochondrial dysfunction, measured by COX4i1 …

Menstrual Pain Trajectories And Their Psychological And Behavioral Predictors, Hannah Marie Alves Hagy

Master's Theses

Despite the high prevalence of menstrual pain (i.e., dysmenorrhea) and the negative impact on quality of life, there is a dearth of research on how menstrual pain changes over time. There is also a critical need to understand psychological and behavioral predictors of these menstrual pain trajectories because dysmenorrhea is a known risk factor for the development of chronic pelvic pain (CPP) and chronic non-pelvic pain (CNPP). Given that current treatments for CPP and CNPP have had limited success, developing preventative strategies for dysmenorrhea is of high importance. Relying on longitudinal survey data collected as part of a larger investigation, …

Kinship Involvement And Strength Development In The Child Welfare System, Nicole Amper Hodgkinson

Master's Theses

For youth involved in the Child Welfare System (CWS), maltreatment and ecological losses pose enormous challenges to healthy development. Kin and fictive kin involvement, a current CWS priority, may have the potential to aid in strength development; however, little is known about its role in this process. The current study explored the following aims: (1) identify the role of kin and fictive kin in strength development (2) investigate the impact of maltreatment on initial strength levels and their development over time and (3) examine the extent to which kinship involvement interacts with prior maltreatment to buffer the impact of maltreatment …

A Fair Share: How Awareness Of Inequality, Allocation Method, And System Justification Affect Perceptions Of Distributive Fairness, David Thomas Igliozzi

Master's Theses

In considering the different ways people view inequality and various proposed solutions,this study draws on classic psychological theories of distributive justice which outline three modes of allocation strategies: equality, equity, and need. While Deustch’s (1975) work on these three allocation alternatives laid the groundwork for years of distributive justice research that would follow, little empirical work has actually experimentally evaluated the conditions under which people might be more or less willing to support equity, equality, or need-based strategies. There is evidence that certain individual difference measures can predict support for redistribution. That is—those who rate highly on system justification, political …

Anthropogenic Litter In Illinois Streams: Monitoring, Distribution, And Relationship To Biological Indicators Of Stream Health, Lauren Wisbrock

Master's Theses

Anthropogenic litter (i.e., trash; AL) is increasing in aquatic ecosystems worldwide. AL shows a patchy, uneven distribution in lotic ecosystems due to heterogeneity in its sources, how it moves, and mechanisms of retention. In addition, the diversity of material types, size, and mobility makes developing techniques to measure AL assemblage in rivers a challenge. In rivers, watershed land-use and riparian features likely impact AL abundance and composition, but this impact is not fully understood. Measuring AL can be time consuming and labor intensive, so rapid assessments are needed for ecosystem managers to quantify the level of AL impairment in a …

Prevalence Of Avoidant/Restrictive Food Intake Disorder And Association With Nutrition Status In Patients With Inflammatory Bowel Diseases, Emily Yelencich

Master's Theses

There is a large body of research on the relationship between inflammatory bowel disease (IBD) and diet; however, few conclusive, generalizable recommendations have been determined. Regardless, IBD patients often alter their normal dietary intake, which is concerning considering the prevalence of malnutrition in the IBD population. Avoidant/restrictive food intake disorder (ARFID) is a feeding disorder that was recently added to the Diagnostic and Statistical Manual of Mental Disorders and its prevalence and impact on the nutritional status of IBD patients has not previously been described. In this study ARFID risk was measured using the Nine-Item ARFID Screen and in the …

Influence Of Night Work On Performance During Lunar Telerobotic Operations, Zachary Luke Glaros

Master's Theses

Real-time, reactive telerobotic mission control operations require personnel to actively operate remotely controlled vehicles or robots in real time. Due to the physical separation of the vehicle from the operator, such operations present additional factors that can influence fatigue (degraded mental performance) and workload (mental and physical cost of task requirements), making it difficult to assess how long an individual can conduct operations safely. The upcoming Volatiles Investigating Polar Exploration Rover will involve remotely controlling a lunar vehicle from an Earth-based mission control station. In order to determine how long personnel could successfully maintain alertness and performance while operating a …

Synthesis And Evaluation Of N-(9'-Acridinyl)-O-Phenylhydroxylamines, Jana Forster

Master's Theses

Anilinoacridines are a class of compounds that are known to intercalate DNA. This class of compounds can be used as a target therapy to combat cell growth and replication. The anilinoacridines, DNA, and topoisomerase II will form a ternary complex that results in numerous strand scissions leading to apoptosis. Previous research has shown that the anilinoacridines can have a short half-life and produce harmful side products as a result of hydrolysis. The half-life could increase if this structure was slightly altered by making a molecule that does not readily hydrolyze. N-(9’-Acridinyl)-O-phenylhydroxylamines can be synthesized in three steps starting with commercially …

Physiological And Anatomical Responses Of Douglas-Fir And Lodgepole Pine To Bark Beetle Attack And Blue-Stain Fungi Inoculations, Robert Walker

Master's Theses

Bark beetles are important native insect pests to conifer forests in North America and their irruptive beetle populations are of serious concern both ecologically and economically. As bark beetles bore into the phloem of a host tree to excavate brood galleries, they simultaneously deposit spores of blue-stain fungi. Both the partial girdling of the tree’s phloem by beetles and the blockage of xylem by fungi can overcome the tree’s defenses and cause its death. To combat colonization by insects and pathogens, conifers allocate large amounts of metabolic resources into defense mechanisms, of which, resin ducts play important roles. As resin …
