Reimagining Bioethics Curricula: Centering Antiracism, Diversity, Equity, And Inclusion, Shika Kalevor, Marie-Laura Allirajah, Isabella Hernandez, Phoebe Ozuah

Presentations

As bioethicists, we engage with social, political, and health care systems that all center on relationality. Part of our responsibility in occupying space within these systems is recognizing where bias, power, and privilege lie, and how our positionality can either contribute to or take away from progress toward a morally conscious society. Bioethicists have the opportunity to remediate preventable harms and address issues of equity, justice, diversity, and oppression. We can also address these issues as core to our growing knowledge base. From our own experiences as bioethics students from multidisciplinary backgrounds, we know that these topics are not sufficiently …

Rorα Suppresses Cancer-Associated Inflammation By Repressing Respiratory Complex I-Dependent Ros Generation, Wei Mao, Gaofeng Xiong, Yuanyuan Wu, Chi Wang, Daret St. Clair, Jai-Da Li, Ren Xu

Markey Cancer Center Faculty Publications

Breast cancer development is associated with macrophage infiltration and differentiation in the tumor microenvironment. Our previous study highlights the crucial function of reactive oxygen species (ROS) in enhancing macrophage infiltration during the disruption of mammary tissue polarity. However, the regulation of ROS and ROS-associated macrophage infiltration in breast cancer has not been fully determined. Previous studies identified retinoid orphan nuclear receptor alpha (RORα) as a potential tumor suppressor in human breast cancer. In the present study, we showed that retinoid orphan nuclear receptor alpha (RORα) significantly decreased ROS levels and inhibited ROS-mediated cytokine expression in breast cancer cells. RORα expression …

Age-Dependent Increase In Tyrosine Level Depletes Tyrosyl-Trna Synthetase And Causes Neuronal Oxidative Dna Damage In Alzheimer’S Disease, Megha Jhanji

Theses and Dissertations

Alzheimer’s disease (AD) is the most common form of dementia, and it currently affects more than 50 million people worldwide. Much of the population develop late-onset AD after 65 and constitute more than 95% of the cases. Currently, there is no definitive cure or way to slow down the progression of this disease that addresses the neurodegeneration and loss of cognitive functions. Although the underlying cause of AD is still unknown, the “amyloid cascade hypothesis” attributed it to the aggregation of amyloid beta (AU+03B2) peptides and has been the focus for targeting most disease-modifying drugs in clinical trials. However, emerging …

With rates of psychiatric illnesses such as depression continuing to rise, additional preclinical models are needed to facilitate translational neuroscience research. In the current study, the raccoon (Procyon lotor) was investigated due to its similarities with primate brains, including comparable proportional neuronal densities, cortical magnification of the forepaw area, and cortical gyrification. Specifically, we report on the cytoarchitectural characteristics of raccoons profiled as high, intermediate, or low solvers in a multiaccess problem-solving task. Isotropic fractionation indicated that high-solvers had significantly more cells in the hippocampus (HC) than the other solving groups; further, a nonsignificant trend suggested that this …

Satellite-Detected Ammonia Changes In The United States: Natural Or Anthropogenic Impacts, Yaqian He, Rongting Xu, Stephen A. Prior, Di Yang, Anni Yang, Jian Chen

United States Department of Agriculture Wildlife Services: Staff Publications

Ammonia (NH3) is the most abundant alkaline component and can react with atmospheric acidic species to form aerosols that can lead to numerous environmental and health issues. Increasing atmospheric NH3 over agricultural regions in the US has been documented. However, spatiotemporal changes of NH3 concentrations over the entire US are still not thoroughly understood, and the factors that drive these changes remain unknown. Herein, we applied the Atmospheric Infrared Sounder (AIRS) monthly NH3 dataset to explore spatiotemporal changes in atmospheric NH3 and the empirical relationships with synthetic N fertilizer application, livestock manure production, and climate factors across the entire US …

Adaptation Of An Artificial Bait To An Automated Aerial Delivery System For Landscape-Scale Brown Treesnake Suppression, Rafael A. Garcia, Thomas W. Mcauliffe, Lorelie P. Bumanlag, Shane R. Siers, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

Dead neonatal mice are currently used as bait for delivery of toxin to invasive brown treesnakes (Boiga irregularis) on Guam; once deployed in the field the mice are highly attractive to the snakes but only for about four days. An artificial bait containing a mixture of fats mimicking those in skin of the mice is also highly attractive to the snakes and remains attractive 2–3 times longer. The artificial bait, however, costs more than the mice, and is more difficult to attach to the capsules of a novel aerial bait delivery system. This paper describes a reformulation of the bait …

During the last half-century, the distribution of golden jackals (Canis aureus) has rapidly increased throughout Europe. Today, golden jackals are thriving in human-dominated landscapes across Southeastern and Central Europe. Most studies on golden jackals have focused on large-scale distribution patterns; to date, little is known about the species’ fine-scale spatial ecology. In this study, we analyzed the movement behavior, space-use and resource selection of six golden jackals fitted with GPS-GSM collars in two study areas in Hungary and Serbia. Two of the jackals were a breeding pair. We found that home range size averaged 11.2 km² (90% …

Effects Of Translocation On Survival Of Nuisance Bears, Javan Bauder, D. Ruid, N. M. Roberts, B. Kohn, M. L. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

Effective mitigation of human–wildlife conflict should aim to reduce conflicts while also minimizing wildlife mortality. Translocation is often used to mitigate human–wildlife conflict but translocated individuals may have reduced survival, which could negatively affect population growth and social acceptance of translocation as a management tool. Yet, non-translocated nuisance individuals may also have low survival due to inherent risks associated with nuisance behavior. We used a 38-year dataset of 1233 marked and translocated nuisance American black bears (Ursus americanus) as a model system with which to evaluate the impacts of translocation on nuisance bear survival. We used multi-state mark-recapture models to …

Threading The Needle: How Humans Influence Predator–Prey Spatiotemporal Interactions In A Multiple-Predator System, Asia Murphy, Duane R. Diefenbach, Mark Ternent, Matt Lovallo, David Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Perceived predation risk and the resulting antipredator behaviour varies across space, time and predator identity. Communities with multiple predators that interact and differ in their use of space, time of activity and hunting mode create a complex landscape for prey to avoid predation. Anthropogenic presence and disturbance have the potential to shift interactions among predators and prey and the where and when encounters occur. We examined how white-tailed deer Odocoileus virginianus fawn spatiotemporal antipredator behaviour differed along an anthropogenic disturbance gradient that had black bears Ursus americanus, coyotes Canis latrans, bobcats Lynx rufus and humans present. We quantified (a) spatial …

Traumatic brain injuries (TBIs) have been labeled as a modern-day epidemic, increasing exponentially with the advancement of technology and society. Gaining a better understanding of the cognitive paths, including the chemical and electrical signals of the brain, neural correlates, and possible interventions for TBI patients allows for the best possible outcome for every patient, and allows for the further advancement of care. By revising and reassessing the ways in which TBIs are categorized and described the prognosis for recovery paints a more realistic view for each individual patient case. The symptoms and impairments that may occur post-injury can be monitored …

Management And Complications Of Enlarged Vestibular Aqueduct And Meniere's Disease, Jessica Birkey, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

Introduction: Vestibular aqueducts follow a route through the inner ear that terminates within the skull and, in most circumstances, aqueducts are narrow and bony. An enlarged vestibular aqueduct (EVA) is most commonly caused by a mutation in the SLC26A4 gene. There are other unidentified environmental and genetic causes that produce EVA as well. At the time this case was reported, no surgeries or treatments existed that could repair an EVA. Case presentation: A bilingual male child presented with congenital bilateral EVAs. His EVAs were accompanied by sensorineural hearing loss and language delay. Discussion: Enlarged vestibular aqueducts can affect language learning …
