The Collective Submitted Works from Honors 2030

Students in the Honors 2030, Inquiries in the Social and Behavioral Sciences course each participated in the URS 2020 as their final project for the course. Dr. Wilson worked with each student as a faculty mentor to create, draft, edit, approve and publish each of the final posters and papers submitted to the 2020 URS for the course

Current concepts on oxidative/carbonyl stress, inflammation and epigenetics in pathogenesis of chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a global health problem, and current therapy for COPD is poorly effective and the mainstays of pharmacotherapy are bronchodilators. A better understanding of the pathobiology of COPD is critical for the development of novel therapies. In the present review, we have discussed the roles of oxidative/aldehyde stress, inflammation/immunity, and chromatin remodeling in the pathogenesis of COPD. Imbalance of oxidant/antioxidant balance caused by cigarette smoke and other pollutants/biomass fuels plays an important role in the pathogenesis of COPD by regulating redox-sensitive transcription factors (e.g. NF-κB), autophagy and unfolded protein response leading to chronic lung inflammatory response. Cigarette smoke also activates canonical/alternative NF-κB pathways and their upstream kinases leading to sustained inflammatory response in lungs. Recently, epigenetic regulation has been shown to be critical for the development of COPD because the expression/activity of enzymes that regulate these epigenetic modifications have been reported to be abnormal in airways of COPD patients. Hence, the significant advances made in understanding the pathophysiology of COPD as described herein will identify novel therapeutic targets for intervening COPD

Agency and inner freedom

This paper concerns the relationship between two questions. The first is a question about inner freedom: What is it to be rendered unfree, not by external obstacles, but by aspects of oneself? The second is a question about agency: What is it to fail at being a thing that genuinely acts, and instead to be a thing that is merely acted upon, passive in relation to its own behaviour? It is widely believed that answers to the first question must rest on or be partly explained by answers to the second. Here I argue that this is a mistake: losses of inner freedom are not, after all, explicable in terms of failures of agency. To establish this conclusion, I consider three familiar lines of thought that appear to tie ideas about inner freedom to ideas about agency, each relating to a different conception of inner freedom: absence of inner constraint, self-government, and absence of determination by external forces. I argue that, in each case, any apparent conceptual reliance on a special conception of agency is merely illusory, the result being that we must allow clear water between our theories of inner freedom and our theories of agency. This conclusion is of significance for contemporary theories of agency and personal autonomy, as well as for ‘positive’ conceptions of political liberty

Effects of wild, semi‐captive, and captive management on male Chiricahua leopard frog sperm quality with implications for conservation breeding programs

Abstract The Chiricahua leopard frog (Lithobates chiricahuensis) is a threatened species endemic to the southwestern United States and Northern Mexico. Captive breeding programs were established to support reintroduction efforts, yet reproductive output has been lower than needed for recovery of the species. This study aimed to evaluate the effects of captivity on amphibian reproduction by (1) determining if captive, semi‐captive, and wild male L. chiricahuensis produce sperm at similar rates and concentration in response to hormone treatment; and (2) evaluating the quality of sperm obtained over time from these populations. Males from captive, semi‐captive, and wild locations were administered a combination of human chorionic gonadotropin and gonadotropin‐releasing hormone to stimulate sperm production and release. A high percentage of males in the captive (60%), semi‐captive (100%), and wild (95.3%) populations produced sperm following treatment. Sperm quality (forward progressive motility and total sperm motility) did not differ between groups. However, sperm quantity (sperm/ml) differed (p < .05) between populations, with semi‐captive and wild males producing higher concentrations of sperm than captive males. These results suggest that Chiricahua leopard frog sperm quantity, but not quality, may become negatively impacted by long‐term captivity in indoor, controlled settings
