Beef Steer Performance On Irrigated Monoculture Legume Pastures Compared With Grass-And Concentrate-Fed Steers, Lance R. Pitcher, Jennifer W. Macadam, Robert E. Ward, Kun Jun Han, Thomas C. Griggs, Xin Dai

Faculty Publications

Fall-or spring-born steers grazed monoculture irrigated birdsfoot trefoil (BFT; Lotus corniculatus L.) or cicer milkvetch (CMV; Astragalus cicer L.) pastures for approximately 12 weeks for 3 years and were compared with steers on concentrate diets. In the 3rd year, an irrigated meadow bromegrass (MBG; Bromus biebersteinii Roem. and Schult.) pasture treatment was added for further comparison. Steer average daily gain (ADG) was 1.31, 0.94, 0.83 and 0.69 kg d−1 on concentrate, ‘Norcen’ BFT, ‘Oberhaunstadter’ BFT, and ‘Monarch’ CMV diets, respectively; ADG on grass pastures was 0.43 kg d−1. The ADG on the concentrate diet was greater than ADG on legume …

Do Mobile Consumers Homogenize The Distribution Of Resources In Stream Food Webs? A Test With Overlapping Fish And Mussel Aggregations, Caryn C. Vaughn, Thomas B. Parr, Traci P. Dubose, Kiza K. Gates, Garrett W. Hopper, Keith B. Gido

Faculty Publications

In streams, unionoid mussels and fish form aggregations that exert bottom-up and top-down effects on food webs, but the magnitude and spatial extent of their effects are controlled by species traits. Sedentary mussels live burrowed in the sediment in patchily distributed dense aggregations (mussel beds) where they filter seston and provide a local, relatively constant nutrient subsidy. In contrast, fish move on and off mussel beds, and thus comprise a transient nutrient subsidy. We asked how overlap between fish and mussels influences nutrient recycling and resource distribution in streams. We conducted an 8-week study in experimental streams where we created …

Role Of Akr1b10 And Akr1b8 In The Pathogenesis Of Non-Alcoholic Steatohepatitis (Nash) In Mouse, Sangam Rajak, Pratima Gupta, Baby Anjum, Sana Raza, Archana Tewari, Sujoy Ghosh, Madhulika Tripathi, Brijesh K. Singh, Rohit A. Sinha

Division of Basic Science Faculty Publications

Non-alcoholic steatohepatitis (NASH) is a clinically important spectrum of non-alcoholic fatty liver disease (NAFLD) in humans. NASH is a stage of NAFLD progression wherein liver steatosis accompanies inflammation and pro-fibrotic events. Presently, there are no approved drugs for NASH, which has become a leading cause of liver transplant worldwide. To discover novel drug targets for NASH, we analyzed a human transcriptomic NASH dataset and found Aldo-keto reductase family 1 member B10 (AKR1B10) as a significantly upregulated gene in livers of human NASH patients. Similarly murine Akr1b10 and Aldo-keto reductase family 1 member B8 (Akr1b8) gene, which is a murine ortholog …

Beyond Appetite Regulation: Targeting Energy Expenditure, Fat Oxidation, And Lean Mass Preservation For Sustainable Weight Loss, Berit Østergaard Christoffersen, Guillermo Sanchez-Delgado, Linu Mary John, Donna H. Ryan, Kirsten Raun, Eric Ravussin

Clinical Research Faculty Publications

New appetite-regulating antiobesity treatments such as semaglutide and agents under investigation such as tirzepatide show promise in achieving weight loss of 15% or more. Energy expenditure, fat oxidation, and lean mass preservation are important determinants of weight loss and weight-loss maintenance beyond appetite regulation. This review discusses prior failures in clinical development of weight-loss drugs targeting energy expenditure and explores novel strategies for targeting energy expenditure: mitochondrial proton leak, uncoupling, dynamics, and biogenesis; futile calcium and substrate cycling; leptin for weight maintenance; increased sympathetic nervous system activity; and browning of white fat. Relevant targets for preserving lean mass are also …

Financial Challenges And Capacity Among African Refugees In The Southern Usa: A Study Of Socio-Demographic Differences, Njeri Kagotho, Jennifer Scott, Mckenzie M. Ketchum, Youn Kyoung Kim, Arati Maleku, Younghee Lim

Faculty Publications

Refugees’ successful integration into US society requires adaptation to economic, financial and social norms. Despite the importance of considering financial challenges (financial stress and financial anxiety) and financial capacity (financial literacy and financial self-efficacy) in reaching personal financial goals, literature examining the relationship between financial challenges and capacity—critical in refugee resettlement and integration—is sparse and fragmented. This study explored financial challenges and capacity amongst resettled African refugees (N ¼ 130) in the southern USA using data from a larger community-based participatory research study that used a mixed-methods approach. We explored socio-demographic differences in financial stress, financial anxiety, financial literacy and …

Exercise As A Moderator Of Persistent Neuroendocrine Symptoms Of Covid-19, Candida J. Rebello, Christopher L. Axelrod, Charles F. Reynolds, Frank L. Greenway, John P. Kirwan

Division of Basic Science Faculty Publications

Precipitated by chronic psychological stress, immune system dysregulation, and a hyperinflammatory state, the sequelae of postacute COVID-19 (long COVID) include depression and new-onset diabetes. We hypothesize that exercise counters the neuropsychiatric and endocrine sequelae of long COVID by inducing the release of circulating factors that mediate the anti-inflammatory response, support brain homeostasis, and increase insulin sensitivity.

Measuring Volatile Emissions From Moss Gametophytes: A Review Of Methodologies And New Applications, Danlyn L. Brennan, Leslie M. Kollar, Scott Kiel, Timea Deakova, Aurélie Laguerre, Stuart F. Mcdaniel, Sarah Eppley, Elliott T. Gall, Todd Rosenstiel

Center for Life in Extreme Environments Publications

Mosses inhabit nearly all terrestrial ecosystems and engage in important interactions with nitrogen-fixing microbes, sperm-dispersing arthropods, and other plants. It is hypothesized that these interactions could be mediated by biogenic volatile organic compounds (BVOCs). Moss BVOCs may play fundamental roles in influencing local ecologies, such as biosphere–atmosphere–hydrosphere communications, physiological and evolutionary dynamics, plant–microbe interactions, and gametophyte stress physiology. Further progress in quantifying the composition, magnitude, and variability of moss BVOC emissions, and their response to environmental drivers and metabolic requirements, is limited by methodological and analytical challenges. We review several sampling techniques with various analytical approaches and describe best practices …

Unraveling Molecular Mechanisms Of Antibiotic Resistance Through Multiscale Simulations And Explainable Machine Learning, Zilin Song

Chemistry Theses and Dissertations

Pathogen resistance to β-lactam antibiotics compromises effective treatments of superbug infections. One major source of β-lactam resistance is the bacterial production of β-lactamases, which could effectively hydrolyze β-lactam drugs. In this thesis, the hydrolysis of various β-lactam antibiotics by class A serine-based β-lactamases (ASβLs) were investigated using hybrid Quantum Mechanical / Molecular Mechanical (QM/MM) minimum energy pathway (MEP) calculations and explainable machine learning (ML) approaches. The TEM-1/benzylpenicillin acylation reaction with QM/MM chain-of-states reaction pathways was firstly revisited. I proposed two decomposition methods for energy contribution analysis based on perturbing ML regression models. Both methods were shown to be model implementation …

Before the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (1) atmospheric turbulence changes at centimetre scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (2) the speed of sound varies at the surface with frequency^2,3 and (3) high-frequency waves are strongly attenuated with distance in CO₂ (refs.^2,3,4). However, theoretical models were uncertain because of a lack of experimental data at low pressure and the difficulty to characterize turbulence or attenuation in a closed environment. Here, using Perseverance …

Working Through Menopause, Bridget J. Crawford, Emily Gold Waldman, Naomi R. Cahn

Elisabeth Haub School of Law Faculty Publications

There are over thirty million people ages 44 to 55 in the civilian labor force in the United States, but the law and legal scholarship are largely silent about a health condition that approximately half of those workers inevitably will experience. Both in the United States and elsewhere, menopause remains mostly a taboo topic, because of cultural stigmas and attitudes about aging and gender. Yet menopause raises critical issues at the intersections of gender equity, disability, aging, transgender rights, and reproductive justice. This Article imagines how the law would change if it accounted for menopause and the associated unequal burdens …

Getting Gideon Right: Eligibility For Appointed Counsel In Texas Misdemeanor Cases, Andrew L.B. Davies, Blane Skiles, Pamela R. Metzger, Janelle Gursoy, Alex Romo

Deason Center Reports

In Gideon v. Wainwright, the U.S. Supreme Court held that the government must provide a criminal defense lawyer for any accused person who cannot afford one. But for too many people, Gideon's promise remains unfulfilled. In Texas, there are no statewide guidelines about who is entitled to a court-appointed lawyer. Instead, counties create their own rules that create serious gaps in constitutional protection. Getting Gideon Right investigates the financial standards that determine an accused person's eligibility for appointed counsel in Texas county courts. The report reveals a patchwork of county court policies that are both complex and severe.

The "Divisive Concepts" Laws And Americans Of Asian Descent, Ilhyung Lee

SMU Law Review Forum

In the past year, a number of states have enacted laws that prohibit public schools from teaching certain lessons about race. The main target of these laws appears to be “critical race theory,” once a theory advanced in legal academia that has now become a “catchall term” for discussions of race and racism. The states mean business and seek to enforce their new or proposed laws by prohibiting state funding for teaching the banned content, withholding funding to local educational agencies or schools in violation, subjecting offending teachers to disciplinary action, and allowing those aggrieved to bring an action at …

Reimagining Near-Earth Space Policy In A Post-Covid World, John C. Barentine, Jessica Heim, Aparna Venkatesan, James Lowenthal, Monica Vidaurri

Astronomy: Faculty Publications

Our planet and our species are at an existential crossroads. In the long term, climate change threatens to upend life as we know it, while the ongoing COVID-19 pandemic revealed that the world is unprepared and ill-equipped to handle acute shocks to its many systems. These shocks exacerbate the inequities and challenges already present prior to COVID in ways that are still evolving in unpredictable directions. As weary nations look toward a post-COVID world, we draw attention to both the injustice and many impacts of the quiet occupation of near-Earth space, which has rapidly escalated during this time of global …

Feasibility Assessment Of Special Management Areas To Enhance Recreational Fisheries And Habitat, Savanna Barry, Thomas T. Ankersen, Edward Camp, Mark Clark, Lauren Griffiths, Micheal Allen

UF Law Faculty Publications

Nearshore recreational fisheries provide tremendous value to the Florida economy. These fisheries are dependent on the availability of high-quality habitat, and sound fisheries management. Habitat can be degraded by several factors, including damage to seagrass flats by propellers of power boats operating in shallow waters (prop scarring). The current fisheries management framework employs regulations limiting harvest by season, fish length, and bag limit (number of fish harvestable per angler per day). Regulations often vary due to regional differences in fishery stocks and population dynamics.

Our team’s overall goal in undertaking this work was to assess the feasibility of creating special …

The Links Between Relationship Maintenance Strategies And Psychological Well-Being In The Context Of Ambivalent Relationships, Stephen M. Yoshimura, Danielle Farley, Kellie Hofstetter, Hillary Loney, Randi Wichman

Communication Studies Faculty Publications

This study examined the extent to which maintaining ambivalent relationships with specific types of relationship maintenance behaviors relates to states of psychological distress and well-being. Survey data from 206 participants indicated that ambivalence toward a relationship partner associated with increased negative affect, and although ambivalence by itself did not relate to any specific relational maintenance behavior, the reported use of positivity to maintain such relationships inversely related to levels of negative affect and depression, whereas the use of openness related to increased levels of negative affect, increased depression, and reduced levels of overall life satisfaction. The results carry implications for …

The Impact Of Anaerobic Exposure And Propionate On The Kinetics And Pathogenesis Of Listeria Monocytogenes, Mackenzie T. Martin

Honors Theses

Listeria monocytogenes is a foodborne pathogen commonly found in ready-to-eat deli and dairy products. This foodborne pathogen is responsible for the disease listeriosis, which disproportionately impacts immunocompromised individuals. This research aims to evaluate how natural intestinal environments influence the pathogenesis of Listeria. One particular environmental condition that has a well-documented effect on Listeria is varying levels of oxygen. Specifically, anaerobic exposure during the growth of Listeria greatly impacts subsequent intracellular pathogenesis. When grown and adapted under anaerobic conditions, Listeria overall exhibits decreased intracellular survival and decreased cell to cell spread. However, the presence of propionate, a natural byproduct of fermentation …

Ghosts’ Stories: Addictive Behaviors And Complicated Grief In George Saunders’ Lincoln In The Bardo, Jc Leishman

Criterion: A Journal of Literary Criticism

When experiencing the natural motions of the grieving process, some individuals encounter an inability to pass this process by a phenomenon known as complicated grief. To deal with the cyclical trauma this causes, the human mind seeks to engage in addictive behaviors (both substantive and behavioral) that work to artificially and momentarily circumvent grief. This process, as it appears in George Saunders' experimental novel, Lincoln in the Bardo, reveals a depth of commentary on human attachments and grieving processes through the lives and narratives of ghosts found in the bardo.

Entropic Interactionist Theory: Reading Social Constructionism Through Thermodynamics And Samuel Beckett, Brie Barron

Criterion: A Journal of Literary Criticism

This essay aims to explain the breakdown of social constructs through the concept of Entropic Interactionist Theory. EIT argues that it is the nature of creations to be vulnerable to the same forces as their creator, and that social constructions (like identity, for example) are subject to the very same physical forces that give rise to humanity’s creative impulse. At its core, EIT is informed by social constructionism and Nietzschean sociological theory, but it names the second law of thermodynamics and the concept of entropy as the driving force behind societal disintegration. The complication with this theory is that it …
