A018: Dual-Process Advantages Of Ball Players In Sport-Related Domains, Xuechen Mao

International Journal of Physical Activity and Health

Background: Based on a dual-process framework, two qualitatively different modes of processing guide human behaviour. Type 1 processes refer to automatic, unconscious processing that can be responsible for Task 1, while Type 2 processes refer to controlled, conscious processing required by Task 2. Although many existing sport psychology studies emphasize that the dual-process model can be applied to the sports domain, this application has shortcomings. The first debate of this application is whether dual-process advantages in athletes are limited to sport-specific realms. Furthermore, although the dual-process framework pays more attention to automatic processes (Type 1 processes), it loses sight of …

Assessing Cover Crop Adoption Factors In The Rio Grande Valley Through A Social-Ecological Perspective, Mackenzie Feldman

Theses and Dissertations

Reducing agriculture’s negative environmental impacts is crucial for mitigating climate change (White, 2021). Cover crops– non-cash crops grown to benefit subsequent cash crops– can slow erosion, improve soil health, enhance water availability, control pests, and increase biodiversity. Despite these benefits, adoption rates remain low, prompting the USDA and other organizations to fund research on increasing their use. Most studies focus on the Midwest and Northeast, and emphasize individual factors over the relationship between structural factors and individual factors that impact farmers’ decisions to adopt cover crops. This USDA-funded study begins to fill this gap by exploring social-ecological factors and how …

Markey Cancer Center Faculty Publications

Nanoparticles (NPs) offer promising potential as therapeutic agents for inflammation-related diseases, owing to their capabilities in drug delivery and immune modulation. In preclinical studies focusing on spinal cord injury (SCI), polymeric NPs have demonstrated the ability to reprogram innate immune cells. This reprogramming results in redirecting immune cells away from the injury site, downregulating pro-inflammatory signaling, and promoting a regenerative environment post-injury. However, to fully understand the mechanisms driving these effects and maximize therapeutic efficacy, it is crucial to assess NP interactions with innate immune cells. This review examines how the physicochemical properties of polymeric NPs influence their modulation of …

Independent Evolution Of Oleate Hydratase Clades In Bacillales Reflects Molecular Convergence, Robert J. Neff, Priscilla C. Lages, Shannon K. Donworth, James D. Brien, Christopher D. Radka

Markey Cancer Center Faculty Publications

Oleate hydratase (OhyA), a flavoenzyme that catalyzes the hydration of unsaturated fatty acids, has been identified in various Bacillales organisms, including those in the Listeria, Lysinibacillus, Paenibacillus, and Staphylococcus genera. In this study, we combine structural biology with molecular and phylogenetic analyses to investigate the evolutionary dynamics of the OhyA protein family within the Bacillales order. Our evolutionary analysis reveals two distinct OhyA clades (clade I and clade II) within Bacillales that, while sharing catalytic function, exhibit significant genomic and structural differences. Our findings suggest that these OhyA clades originated from independent evolutionary processes through convergent evolution rather than gene …

Stampley, Gregory Davis, Zhen Li, Eunhan Cho, Youyoung Kim, Jake Doiron, Guillaume Spielmann, Sujoy Ghosh, Sanjiv J. Shah, Brian A. Irving, David J. Lefer, Timothy D. Allerton

School of Graduate Studies Faculty Publications

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a “2-hit” model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF. These results underscore the importance of skeletal muscle metabolism to improve exercise intolerance in HFpEF.
