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 …

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. …

The current study recruited three men who were full-time family caregivers for women (spouses, their mother). The study assessed the care recipients’ need for scaffolding of instrumental tasks and the caregivers’ perception thereof and then trained the caregivers in task analysis and prompting. An additive treatment design examined the differential effects of a two-part training intervention on caregivers’ perceptions of the need …

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.

Everything Old Is Q Again: An Analysis Of The Resurgent #Pizzagate Myth In Social Media, Bond Benton, Daniela Peterka-Benton

College of Communication and Media Scholarship and Creative Works

On November 28, 2023, X CEO Elon Musk posted a meme suggesting that the #pizzagate conspiracy had been suppressed by powerful forces complicit in the exploitation of children. The #pizzagate conspiracy presumed that elites had organized a ring serving pedophiles in the basement of a pizzeria in Washington D.C. The conspiracy was debunked in major news outlets with social media platforms such as Facebook banning such content, as well (BBC News). These efforts ultimately did not prevent #pizzagate from morphing into the QAnon conspiracy that would galvanize multiple extremist political movements (Bleakley). Specifically, however, #pizzagate as a discrete narrative was …
