Investigation Of Drp1 Inhibition As Potential Therapy In Pesticide-Based Models Of Parkinson's Disease, Jennifer Rhea Pinnell

Other Faculty of Health Theses

In this study I explored the impact of Drp1 inhibition on pathology in two different pesticide-based models of Parkinson’s disease, and found that paraquat induced autophagy blockade in vitro, which was abrogated by inhibition of Drp1 function through siRNA knockdown or expression of the Drp1K38A dominant negative. Rotenone and paraquat are two pesticides implicated in the pathophysiology and progression of Parkinson’s disease, a hypokinetic neurodegenerative disorder which results in motor and cognitive changes in patients. Previous studies confirmed pesticide-induced loss of dopaminergic neurons in the substantia nigra pars compacta in animal models, however further research was necessary to explore the …

An Exploration Of Religious Practice As A Valued Occupation, Patricia Eyres

Other Faculty of Health Theses

Background: Religion touches our everyday lives. Some have a deeply held faith while others engage infrequently in rites of passage such as marriage or funerals, but religion is a common worldwide phenomenon. Globally, millions of people engage in religious practice or religious ‘doing’ daily, but occupational science has not explored this common occupation widely, and occupational therapists continue to struggle to consider religious practice within the occupational needs of their clients. Within increasingly multi-cultural and multi-faith communities, it is imperative that the occupation of religious practice is better understood and considered within practice. Method: An auto/biographical overarching research orientation is …

The Leading Role Of The Language Phenomenon In Brain Activity, Minaxanum Hajiyeva

Khazar Journal of Humanities and Social Sciences

One of the most prime examples of a multidisciplinary field, Cogntive Lingusitics explores language as a cognitive mechanism in the coding and transformation of information. On the other hand, Neurolinguistics, combining two major sciences and studying the functional course of consciousness, deals with cognitive processes and the relationship between the brain and them. In the scientific development of its History/ Archaeology, a number of different research areas related to the study of the functionality of the brain hemispheres are noteworthy. The different functions in the brain mechanism benefit from cognition, concepts, conceptsphers, and other necessary elements. Cognitive linguistics dealing with …

Zika Virus Inactivates Polyamine Catabolism Via Alternative Splicing To Enhance Infection, Marion Lea Graham

Master's Theses

During viral infection, the virus and host must compete for resources inside the cell. One of these resources is polyamines. Polyamines are small, positively charged molecules that are found in all eukaryotic cells. They play a key role in several cellular functions including growth and proliferation, transcription and translation, and membrane stability. Viruses also rely polyamines for productive replication, utilizing them during DNA/RNa polymerization, nucleic acid packaging, and protein synthesis. in response to a virus infecting a host cell, the host cell will begin to regulate polyamine levels as a way to combat the infection. Polyamine levels are regulated by …

Decreasing Women's Endorsement Of Benevolent Sexism, Kelsey Berryman

Master's Theses

The aim of the current study was to reduce women's endorsement for benevolent sexist beliefs. the intervention aimed to educate women about the prevalence and seriousness of benevolent sexism. as this is a subtle and deceptively positive type of sexism, women are particularly susceptible in endorsing it (Glick & Fiske, 2001). in order to increase awareness for benevolent sexism in their everyday lives, some participants read an informational text about the pervasiveness and harmfulness of benevolent sexism in the U.S. This text was read after participants had already written about a time they engaged in benevolent sexism to elicit negative …

Queer Monstrosity: Dis/Ability, Sexuality, And Gender, Savannah Olivia Aldridge

Master's Theses

The queer monster feeds, yet what does it feed on? What does it look like? Is it considered homosexual in Nature? Does one think of it as a source of camp or pure fear? It consumes us, literally. as a bioweapon that shoots and eats and destroys. It has and always will be the feared/ spectated/ and degraded€¦ the dis/abled queer. I investigate 'queer monstrosity' as a schizophrenic, trans feminine academic who lives multiple lives. There are three parts to my inquiry that is focused on this creation of lived experience: gender, sexuality, and dis/ability. How does including dis/ability in …

Predicting Drug Misuse Status Using Machine Learning On Electronic Health Records, Robert Arnold Kania

Master's Theses

Substance misuse is a major problem in the world. in 2014, as many as 52,404 deaths in the US were caused by drug overdoses. in 2001, the monetary cost of drug misuse has been estimated to be 414 billion dollars. in this work, we explore the use of different machine learning algorithms in the prediction of cocaine misuse using structured and unstructured data found in electronic health records. These records contain various attributes that can help with this prediction, including but not limited to chart text data, previous diagnoses of certain diseases and information about the area the patient lives …

Investigating The Role Of Hypusine In Viral Translation And Infection, Jeremy Joseph Esin

Master's Theses

Polyamines are small, positively charged, molecules found in eukaryotic cells with roles in cellular function and viral infection. in previous work we have shown RNa viruses, including bunyaviruses, to be sensitive to polyamine depletion, but exact mechanisms are unknown. Bunyaviruses are emerging pathogens that cause encephalitis, hemorrhagic fevers, and meningitis. Rift Valley Fever Virus is a bunyavirus that infects both humans and livestock with severe mortality and morbidity. in previous work done with Rift Valley Fever Virus polyamine depleted results in noninfectious interfering particles without affecting the shape or size of the particles. Here, I investigate a specific metabolic pathway …

Optimizing Gene Expression Prediction And Omics Integration In Populations Of African Ancestry, Paul Chukwuebuka Okoro

Master's Theses

Popular transcriptome imputation methods such as PrediXcan and FUSIon use parametric linear assumptions, and thus are unable to flexibly model the complex genetic architecture of the transcriptome. Although non-linear modeling has been shown to improve imputation performance, replicability and potential cross-population differences have not been adequately studied. Therefore, to optimize imputation performance across global populations, we used the non-linear machine learning (ML) models random forest (RF), support vector regression (SVR), and K nearest neighbor (KNN) to build transcriptome imputation models, and evaluated their performance in comparison to elastic net (EN). We trained gene expression prediction models using genotype and blood …

Tumor Immunology: Understanding The Immune System And Cancer To Enhance The Efficacy Of Cancer Immunotherapies, Natasha Malibu Lenart

Master's Theses

Tumor cells are notorious for their ability to escape immune surveillance, but developments in the understanding of the tumor microenvironment and how the immune system can be re-activated in tumors have had significant clinical impact. Commercially available and experimental methods such as adoptive cellular therapy, cytokine stimulation, and immune checkpoint blockade are promising immunotherapies for a variety of cancers, including solid tumors and hematological malignancies. However, induction of persistent, long-term anti-tumor immunity after initial treatment is infamously difficult. as a result, scientists are searching for new approaches to improve established immunotherapies. by employing combination treatments or enhancing the functionality of …

The Longitudinal Relationship Between Callous-Unemotional Traits And Exposure To Community Violence: Examining Primary And Secondary Psychopathy In Serious Adolescent Offenders, Elizabeth Sargent

Master's Theses

in youth, psychopathy is often represented by callous-unemotional traits, characterized by a lack of guilt and empathy. While justice-involved youth can exhibit such traits, less research has been done in adolescents than has been with adults in the justice system. Still, previous research supports that callous-unemotional traits in particular can predict higher risk for adverse outcomes and violent behavior in youth. Various vulnerabilities and experiences contribute to the development of callous-unemotional traits, and while some individuals with psychopathic traits are thought to have been born with an innate inability to feel empathy (primary psychopathy), others may experience psychological distress in …

Latino Parents' Acculturative Stress And Their Preschoolers' Prosocial Development: Testing The Mediating Role Of Parenting Style, Zahra Fatima Naqi

Master's Theses

Studies increasingly recognize the importance of cultural factors when studying the development of immigrant children from low-income backgrounds. There is reason to believe that parents' acculturative stress may be linked to children's prosocial development, via parenting. the present study included a sample of immigrant Latino parents of 3- to 5-year-old Head Start preschoolers (N = 28) to examine how parents' acculturative stress might be associated with children's prosocial behavior at home, as reported by parents, and at school, as reported by teachers. Furthermore, it studied whether this linkage is mediated by warm, supportive, and hostile parenting practices. Results indicated that …

Condition Severity And Parent Psychosocial Functioning In Families Of Youth With Spina Bifida: The Role Of Parental Attitudes And Beliefs, Elicia Wartman

Master's Theses

Past research suggests that parents of youth with spina bifida (SB) have worse psychosocial outcomes than parents of typically developing youth. SB is a complex medical condition that is accompanied by varying degrees of physical disability and cognitive deficits. Research on stress and coping suggests that parents' attitudes and beliefs may contribute to their own psychosocial adjustment. This study unpacks condition severity and examines the role of severity of condition-related factors in predicting parental adjustment and parental attitudes and beliefs. Participants were recruited as part of a larger longitudinal study. Information on condition severity, including type of SB, lesion level, …

The Creation And Evolution Of Introductory Courses In Women's Studies Programs, Tori Kay Olson

Master's Theses

This study seeks to understand what affects knowledge production in introductory women's studies courses. Using critical discourse analysis, the study looks at the archives of two very different programs within the Chicago area. the two programs studied, Loyola University Chicago and University of Illinois€”Chicago, offer two different examples of how women's studies programs were created and evolved, and how this influenced the knowledge production in their introductory courses. in addition to the archival materials of these two universities, this study relies on various reports and accounts written by women's studies scholars during the same timeframe as the documented archival material …

Trajectories Of Adaptive Functioning Among Youth With Spina Bifida: The Influence Of Neurocognitive Functioning And Parental Scaffolding, Adrien Winning

Master's Theses

Youth with spina bifida (SB), a congenital birth defect affecting the central nervous system, are at risk of experiencing an array of psychosocial and functional deficits (Copp et al., 2015; Holmbeck et al., 2003). Indeed, previous research has documented difficulties across the three adaptive functioning domains outlined by the American Association on Intellectual and Developmental Disabilities (AAIDD): conceptual (e.g., communication, self-direction, functional academics), social (e.g., interpersonal skills), and practical (e.g., self-care, navigating health-care; Copp et al., 2015). Despite this evidence, whether or not children with SB typically acquire skills across development is largely unknown. Additionally, little is known about risk …

Enabling The Clinical Detection Of Human Papilloma Virus (Hpv) To Enhance Effective Diagnosis And Research, Jennifer Sackey

Master's Theses

Human Papilloma Virus (HPV) is one of the most common sexually transmitted infections. There are over 150 different genotypes of HPV. Some cause benign warts, while others cause several types of cancer. Subunit vaccines comprised of the capsid protein from an increasing number of HPV genotypes have been developed; however, the vaccines are prophylactic and are documented to protect against only 9 of the HPV genotypes. Importantly, there are also significant limitations in the clinical detection of HPV. Current clinical tests can only specifically identify HPV16 and HPV18. One of the test also detects 12 of the other high-oncogenic risk …

A Susceptibility Study Of Urinary Isolates To Methenamine Hippurate And Its Metabolites, Nancy Sloan

Master's Theses

Urinary Tract Infection (UTI) is one of the most common bacterial infections in adult women. Treatment is one of the most common reasons for antibiotic prescription. the rise of antibiotic-resistant infections coupled with the shortage of new antibiotics creates an urgent need for alternative non-antibiotic treatments. One alternative is methenamine hippurate (MH), which is a non-antibiotic prophylaxis. It is reported to be active against some common uropathogens including Escherichia coli and Enterococcus species, but its effects on the newly discovered bladder microbiota (urobiome) are undocumented. Given this knowledge gap, this study aimed to evaluate the drug's spectrum of susceptibility on …

Determining Interactions Between Bacteriophage And Urinary Microbiome Lysogens, Michael Bochert

Master's Theses

Bacteriophages (phages) are viruses that infect bacteria. They are the most abundant life forms on earth. It is estimated that there are approximately 10³⁰ phages on the planet (Chibani-Chennoufi et al. 2004). They outnumber their bacterial hosts approximately 10 to 1. Bacteria inhabit most niches on the planet including the human body, where they play critical roles in health and disease. Since phages shape bacterial populations the same way that viruses, such as smallpox and measles, shaped human populations, it is important to understand how they interact with their bacterial hosts. The majority of the phages that we know of …

Effects Of Optic Nerve Head Astrocyte-Derived Exosomes On Neuronal Survival And Differentiation In Vitro In A Model For Exfoliation Glaucoma, Harsh Nilesh Hariani

Master's Theses

Exfoliation glaucoma (XFG) is characterized by deposition of exfoliation material at the trabecular meshwork thereby blocking aqueous outflow and consequently increasing intraocular pressure (IOP). Elevated IOP initiates glaucomatous biomechanical damage at the optic nerve head (ONH) eventually resulting in retinal neuronal death and vision loss. The major cell type at ONH are ONH astrocytes (ONHA). A chronic downregulation of LOXL1 expression has been reported in ONH of XFG patients. We hypothesized that wild-type and LOXL1 knock-down ONHA derived exosomes have differential effects on neurons in vitro.We here report that ONHAs release exosomes, which can be taken up by astrocytes and …
