Investigation Of Hydrogen Gas Production And Motility In Δselab And Δfdhf Mutants Of Clostridioides Difficile, Ria D. Gupta

Honors Undergraduate Theses

Clostridioides difficile is a Gram-positive, spore-forming, anaerobic bacterium and the leading cause of antibiotic-associated diarrhea worldwide. During infection, antibiotic-induced disruption of the gut microbiota allows C. difficile to colonize and proliferate. Motility, enabled by flagella, is an important factor in colonization and may be influenced by metabolic activity. Recent experiments have observed gas production during C. difficile motility assays, but the biochemical basis of this phenomenon remains unknown. Because gas formation in other bacteria such as E. coli involves the formate hydrogenlyase complex and the enzyme formate dehydrogenase (FDH), we hypothesize that C. difficile gas production under motility conditions is …

Implementing Holograms To Perform Cognitive Health History Screenings, Franchesca I. Gonzalez

Honors Undergraduate Theses

Marginalized populations, defined as a group of individuals who experience systematic disadvantages due to various social identity factors (Oxford Review, n.d.), experience uneven barriers to cognitive and mental health assessments, including socioeconomic, linguistic, and educational inequities, that contribute to misdiagnosis (Petersen et al., 2018, Saeed & Masters, 2021). This study investigates the feasibility of hologram-based patient simulations as an educational intervention for undergraduate nursing and graduate Nurse Practitioner students. Culturally representative, three-dimensional holographic patients were created to replicate complex geriatric encounters and facilitate cognitive health screenings. Established assessment tools, including the Mini-Mental Status Examination, Patient Health Questionnaire 2 and Patient …

Exploring The Link Between Relationship Status And Emotion Regulation Strategy Use, Abigail A. Echols

Honors Undergraduate Theses

Romantic relationships affect many areas of life and are important sources of interpersonal emotion regulation, yet little research has investigated whether relationship status influences emotion regulation strategy use and emotion dysregulation. Considering that the types of emotion regulation strategies individuals use significantly affect their well-being, understanding the link between relationship status and emotion regulation strategy use is important. This study compared single, partnered, and recently separated individuals’ emotion dysregulation and use of eleven intrapersonal and eleven interpersonal emotion regulation strategies in general (i.e., trait) and in a specific situation (i.e., state) through retrospective self-report scales and an autobiographical writing task. …

Ultra-Plex Immunofluorescence Stainings To Classify Precancerous Lesions For The Stratification Of Their Risk For Progression Toward Esophageal Squamous Cell Carcinoma, Arthi Jaishankar

Honors Undergraduate Theses

Esophageal squamous cell carcinoma (ESCC) is the most common and fatal type of esophageal cancer since it is usually only diagnosed at a later stage. Similar to other cancers, ESCC arises through precursor lesions which are known as dysplasias and occurs when cells have uncontrolled growth and changes to both the tissue structure and gene expression. Clinical intervention at the precancerous stage would greatly improve survival rates, however predicting which lesions will actually become malignant continues to be a challenge. The current traditional method for ESCC diagnosis is hematoxylin and eosin (H&E) histopathology, but it is not sufficient for predicting …

Effect Of Sapropterin Dihydrochloride On Neuropsychiatric Functions For Individuals With Phenylketonuria: A Systematic Review, Ricky Lin

Honors Undergraduate Theses

Phenylketonuria (PKU) is a rare metabolic disorder that occurs in approximately 1 in 10,000 births worldwide. Individuals with PKU cannot properly metabolize phenylalanine (Phe) due to a deficiency in phenylalanine hydroxylase (PAH), leading to elevated Phe levels and associated cognitive and neuropsychiatric impairments. Although early dietary management has reduced the risk of severe intellectual disability, many individuals with PKU continue to experience deficits in attention, executive functions, and mood regulation. Sapropterin dihydrochloride, a synthetic form of the PAH cofactor tetrahydrobiopterin (BH4), offers a pharmacological alternative that enhances residual enzyme activity in responsive individuals. While its efficacy in lowering blood Phe …

Why Some Companies Weather Trade Was Better Than Others?, Di Fan, Daphne W. Yiu, Pengcheng Ma, Lin Cui

Research Collection Lee Kong Chian School Of Business

In 2018, the U.S. government levied tariffs affecting more than $250 billion of Chinese products. As a result, many American buyers began turning to alternative suppliers to avoid the significant new costs associated with purchasing from China. Recent research found that transactions between U.S. buyers and Chinese suppliers fell by more than 18% immediately following the start of the trade war. However, the study also found that not all companies were affected equally: Chinese firms that were more innovative or more socially responsible were more likely to retain their U.S. buyers, while buyers were more likely to distance themselves from …

Integrated Behavioral Health In Pediatric Primary Care: Identifying Latent Patient Subgroups And Differential Outcomes, Karen Glownia

Master's Theses and Doctoral Dissertations

Fifty percent of children do not receive care for their mental health concerns, while 95% are seen annually within primary care by age 6. Individual, cultural, and systemic barriers limit access to mental health care. Integrating mental health services into primary care has the potential to increase awareness, reduce costs, and decrease stigma. However, integrated primary care often relies on a brief and targeted intervention approach that may not be suitable for all families. Therefore, it is important to examine differential outcomes within this setting. Methods: This study analyzed retrospective data from 3,494 new patient medical records at a large …

Latent Classes Of Comorbid Clinical Presentations For Patients With Psychogenic Non-Epileptic Seizures, Joseph W. Tu

Master's Theses and Doctoral Dissertations

Psychogenic non-epileptic seizures (PNES) are episodes of motor, sensory, and/or cognitive seizures without detectable epileptic activity. The integrative cognitive model conceptualizes PNES as an activation of learned mental representations of a seizure often combined with concurrent physiological arousal. PNES are not treatable by antiepileptic medications and are often accompanied by psychiatric and medical comorbidities, complicating treatment following diagnosis. Further, individuals with PNES often incur greater medical costs through hospital admissions and emergency department visits. Multidisciplinary care including behavioral health interventions like cognitive behavior therapy have demonstrated initial success at reducing seizure frequency but impacts on healthcare utilization are unknown. Patients …
