A “couples YouTube channel” is a YouTube channel where a real-life romantic couple posts videos about their relationship. On YouTube there are hundreds of such channels, and some are so popular that those couples actually make a living creating and sharing their stories. How do they do this? More specifically: what marketing techniques, specifically storytelling practices, do these YouTube couples use to resonate with audiences?

This exploratory, qualitative study seeks to answer this question through a thematic textual analysis of three couples YouTube channels. Using narrative theory and parasocial interaction as theoretical frameworks, the study interpretively analyzes a total of …

The Role Of The Erbb Signaling Pathway In Cardiovascular Progenitor Cell-Based Repair, Christopher Ramos

Electronic Theses, Projects, and Dissertations

Adult mammalian hearts lack self-renewal and proliferative capabilities necessary for cardiovascular regeneration. Current treatments using cardiac progenitor cells (CPCs) for cell-based repair do not restore cardiac function in patients who experience a myocardial infarction (MI). Our laboratory has been studying Islet-1+ neonatal CPCs as a promising candidate for cell-based repair due to their ability to significantly improve cardiac function after MI in sheep. The current study addresses the hypothesis that the ERBB pathway is linked to the Hippo-pathway to activate YAP1 by the involvement of an autocrine loop that upregulates neuregulin (NRG). In our sheep model of MI and cardiovascular …

School of Dentistry Faculty Publications

The fungus Candida albicans is an opportunistic pathogen that can exploit imbalances in microbiome composition to invade its human host, causing pathologies ranging from vaginal candidiasis to fungal sepsis. Bacteria of the genus Lactobacillus are colonizers of human mucosa and can produce compounds with bioactivity against C. albicans. Here, we show that some Lactobacillus species produce a small molecule under laboratory conditions that blocks the C. albicans yeast-to-filament transition, an important virulence trait. It remains unexplored whether the compound is produced in the context of the human host. Bioassay-guided fractionation of Lactobacillus-conditioned medium linked this activity to 1-acetyl-β-carboline (1-ABC). We …

Cardenolide, Potassium, And Pyrethroid Insecticide Combinations Reduce Growth And Survival Of Monarch Butterfly Caterpillars (Lepidoptera: Nymphalidae), Annie J. Krueger, Emily A. Robinson, Thomas J. Weissling, Ana M. Vélez, Troy D. Anderson

Department of Entomology: Faculty Publications

The monarch butterfly, Danaus plexippus L., has evolved to be insensitive to milkweed cardenolides via genetic modifications of Na⁺/K⁺-ATPase. There is concern for insecticide exposures near agriculture, with little information on monarch caterpillar toxicology. It is unclear how cardenolide insensitivity may affect the sensitivity of monarch caterpillars to pyrethroid insecticides. Additionally, potassium fertilizers may affect monarch caterpillar physiology and cardenolide sequestration. Here, we investigated the growth, survival, and development of caterpillars exposed to the cardenolide ouabain, bifenthrin, and potassium chloride (KCl) alone and in combination. Caterpillars were either exposed to (1) ouabain from third- to fifth-instar …

The selection of an economical carbon source is a fundamental parameter to establish a successful industrial succinic acid (SA) bioprocess. In this work, corn fiber (CF), a renewable and an inexpensive source of carbohydrates, was successfully used for bioproduction of SA. Optimized liquid hot water (LHW) pretreatment followed by enzymatic hydrolysis were used to obtain corn fiber hydrolysate (CFH). Results in batch fermentation with Actinobacillus succinogenes showed that a control solution mimicking CFH produced 28.7 g/L of SA with a yield of 0.67 g SA/g sugars, while fermentation of CFH produced 27.8 g/L of SA with a yield of 0.61 …

Narrative Review-Drug Delivery In Age-Related Macular Degeneration, Rachel Israilevich, Raziyeh Mahmoudzadeh, Mirataollah Salabati, David Xu

Wills Eye Hospital Papers

This narrative review highlights routes of ocular drug delivery for age-related macular degeneration (AMD). AMD is the leading cause of irreversible blindness in industrialized countries and accounts for 8.7% of blindness worldwide. Advanced AMD can be classified into two subtypes: late-stage dry AMD [known as geographic atrophy (GA)] and neovascular AMD (nAMD). GA is often bilateral and results from progressive and irreversible loss of photoreceptors and areas of the retinal pigment epithelium. Wet AMD is characterized by angiogenesis from the choroid to the normally avascular regions underneath the retinal pigment epithelium (RPE) or retina, a process known as choroidal neovascularization …

Movin’ On Up? A Survey Experiment On Mobility Enhancing Policies, Jared Barton, Xiaofei Pan

Economics Faculty Journal Articles

We use a nationwide survey experiment in the United States to measure whether information on intergenerational economic mobility or policy-specific arguments influence support for six pro-mobility policies advocated by political entrepreneurs. We find the information treatments do not affect support, but the argument treatments significantly increase support for three of the policies. We also include a behavioral measure by allowing respondents the opportunity to write their U.S. Senators. We find argument treatments significantly increase the likelihood that letters address economic mobility and significantly promote advocacy for that policy in the letter, but no increase in advocacy from the information treatments. …
