Comparison Of Human Urinary Exosomes Isolated Via Ultracentrifugation Alone Versus Ultracentrifugation Followed By Sec Column-Purification, Kun Huang, Sudha Garimella, Alyssa Clay-Gilmour, Lucia Vojtech, Bridget Armstrong, Madison Bessonny, Alexis Stamatikos

Faculty Publications

Chronic kidney disease is a progressive, incurable condition that involves a gradual loss of kidney function. While there are no non-invasive biomarkers available to determine whether individuals are susceptible to developing chronic kidney disease, small RNAs within urinary exosomes have recently emerged as a potential candidate to use for assessing renal function. Ultracentrifugation is the gold standard for urinary exosome isolation. However, extravesicular small RNA contamination can occur when isolating exosomes from biological fluids using ultracentrifugation, which may lead to misidentifying the presence of certain small RNA species in human urinary exosomes. Therefore, we characterized human urinary exosomal preparations isolated …

Faculty Publications

Catfish are the predominant U.S. aquacultural product. However, byproducts from filleting, including bones that are high in calcium, typically go to waste or are sold as a low-valued feed. This research evaluated the potential use of catfish bone powder (CBP; 21.07% calcium) as a food ingredient. Catfish fillet strips were dredged with a breading mix (CBPM) containing 0% (0CBPM), 10% (10CBPM), and 20% (20CBPM) CBP before frying. Consumers (N = 211) evaluated sensory liking (nine-point hedonic scale) and attribute intensity (JAR scale), emotions (check-all-that-apply), and purchase intent (PI, yes/no) of samples. Color and texture were measured instrumentally. CBP did not …

Preemption & Gender & Racial (In)Equity: Why State Tort Law Is Needed In The Cosmetic Context, Marie C. Boyd

Faculty Publications

Much of the legal scholarship on the preemption of state tort law in the food and drug context and beyond has focused on issues of federalism. While the literature has considered the relationship between state tort law and the regulatory system, it has not generally explored the impact the federal preemption of state tort law may have on women and people of color. Similarly, while the literature has grappled with gender and racial justice issues in the tort system, including in the context of tort reform, it has largely not examined the gender and racial equity issues raised by federal …

Dispersed Crude Oil Induces Dysbiosis In The Red Snapper Lutjanus Campechanus External Microbiota, Andrew M. Tarnecki, Christelle Miller, Tracy A. Sherwood, Robert J. Griffitt, Ryan W. Schloesser, Dana L. Wetzel

Faculty Publications

The fish external microbiota competitively excludes primary pathogens and prevents the proliferation of opportunists. A shift from healthy microbiota composition, known as dysbiosis, may be triggered by environmental stressors and increases host susceptibility to disease. The Deepwater Horizon (DWH) oil spill was a significant stressor event in the Gulf of Mexico. Despite anecdotal reports of skin lesions on fishes following the oil spill, little information is available on the impact of dispersed oil on the fish external microbiota. In this study, juvenile red snapper (Lutjanus campechanus) were exposed to a chemically enhanced water-accommodated fraction (CEWAF) of Corexit 9500/DWH …

Reassessing The Role Of Anthropogenic Climate Change In The Extinction Of Silphium, Paul Pollaro, Paul Robertson

Faculty Publications

The famed ancient herb, known to the Romans as silphium (Greeksilphion), is widely regarded as the first recorded instance of human-induced species extinction. Modern scholars have largely credited direct exploitation (e.g., over-harvesting; over-grazing) as the primary cause of silphium's extinction, due to an overwhelming demand for the plant in ancient times. Recent research has revealed strict cold-stratification requirements for the germination of silphium's closest living relatives, revealing the likelihood that silphium shared these same germination requirements. Documented environmental changes in ancient Cyrenaica (e.g., widespread deforestation; cropland expansion) likely resulted in accelerated rates of desertification throughout the region as well as …

Food, Freedom, Fairness, And The Family Farm, Robin M. Rotman, Sophie Mendelson

Faculty Publications

The concept of the “family farm” holds powerful sway within the American narrative, embodying both nostalgia for an imagined past and anxiety for a future perceived to be under threat. Since the founding of the United States, this cultural ideal has been invoked in support of a rosy vision of agrarian democracy while obscuring the ways in which the U.S. Department of Agriculture’s codified definition of “family farm” has unfairly aggregated advantages for the benefit of a particular kind of family (nuclear) and farmer (white, male, straight). At the same time, consumers are misled by an under-interrogated conflation of family …

No Guts About It: Captivity, But Not Neophobia Phenotype, Influences The Cloacal Microbiome Of House Sparrows (Passer Domesticus), T. R. Kelly, A. E. Vinson, G. M. King, C. R. Lattin

Faculty Publications

Behavioral traits such as anxiety and depression have been linked to diversity of the gut microbiome in humans, domesticated animals, and lab-bred model species, but the extent to which this link exists in wild animals, and thus its eco- logical relevance, is poorly understood. We examined the relationship between a behavioral trait (neophobia) and the cloacal microbiome in wild house sparrows ( Passer domesticus, n = 22) to determine whether gut microbial diversity is related to per- sonality in a wild animal. We swabbed the cloaca immediately upon capture, assessed neophobia phenotypes in the lab, and then swabbed the cloaca …

Eviction Courts, Kathryn A. Sabbeth

Faculty Publications

This Article examines the legal mechanics of the courts that issue eviction orders. It analyzes these courts in the context of the COVID-19 pandemic and the federal eviction moratoria. The eviction phenomenon preceded the pandemic, but the pandemic exaggerated many of its features. How the eviction courts responded to the eviction moratoria reveals a great deal about how these fora have been functioning all along. While the eviction moratoria were important, the design of eviction courts limited their impact.

The Article identifies ten groups of laws that structure critical design features of eviction courts: (1) filing fee statutes that make …

Local Context And Post-Crisis Social Venture Creation, Sergey Anokhin, Todd Morgan, Lisa Jones Christensen, William Schulze

Faculty Publications

Research summary: We investigate the effects of local market and government failure on the creation of social ventures in the context of post-crisis recovery during the period following the dot-com crisis and ending before the housing bubble burst across all Ohio counties. Drawing on social embeddedness theory, we posit that social venture creation rates vary across local contexts and are higher in communities characterized by market and government failures. Longitudinal contextual data from 88 Ohio counties indicates that situations characterized by failures of both types are especially conducive to the creation of local social enterprises. We address the shortage of …

Parent–Child Leisure And Parent Affect: The Role Of Family Structure, Camilla Hodge, Jocelyn Wikle

Faculty Publications

This study evaluates differences in parent–child leisure and parent affect across single- and two-parent families. The Ecology of Family Experiences framework suggests contextual factors such as family structure and the novelty of the activity environment contribute to heterogeneity in how parents experience leisure, partly because constraints may differ across family structures. Using a large, nationally representative data sample of parents from the American Time Use Survey (N = 78,353), this study shows single-parents experience leisure deficits compared to other parents, and leisure deficits are greatest in home-based leisure. Additionally, using a subsample (N = 16,214), we found that at-home leisure …
