Covid-19 Lockdowns: Exacerbating The Silent Pandemic, David Gomez, Eric V. Neufeld, James W. Hicks, Brett A. Dolezal

International Journal of Exercise Science

International Journal of Exercise Science 14(3): 1256-1260, 2021. The global medical community has exalted the vaccine as the champion solution to end the violent toll inflicted by COVID-19. While the role of vaccines cannot be undervalued in wide-scale intervention, presenting them as the sole solution exonerates individuals of the importance of taking ownership over their lifestyle choices. This editorial focuses on the importance of physical activity as a crucial component of COVID-19 prevention programs and a long-term investment against chronic diseases.

Time Spent Jogging/Running And Telomere Length In 5805 U.S. Adults, Christina M. Blackmon, Larry A. Tucker

International Journal of Exercise Science: Conference Proceedings

A scientifically accepted measure of biological aging is the length of telomeres. Telomeres shorten with each year of life. Although age is the primary driving force, lifestyle can also have a substantial effect on telomere length. PURPOSE: The aim of this study was to investigate the degree to which minutes spent jogging or running per week accounted for differences in leukocyte telomere length (LTL) in a randomly selected sample of 5805 U.S. adults. METHODS: A cross-sectional design was employed using data from the National Health and Nutrition Examination Survey (NHANES) and findings are generalizable to the U.S. adult population. Time …

Heartwork In The Artwork: In-Service Music Educator Professional Development In Việt Nam, Kính T. Vū, Jason Saetta, Adam Shekleton

Visions of Research in Music Education

Teacher professional development (PD) occurs at many times throughout the school year and sometimes during the summer. Most music educators are familiar with back-to-school or election day in-service training that focus teachers' attention on all-school policies, procedures, initiatives, or directives. These topics often leave teachers wondering how these exercises will encourage personal reflection, thoughtful discussions, or innovative practices particular to their music teaching lives. In this paper, we explore two Massachusetts music-band directors' selfdesigned professional development projects in Việt Nam and share how travel-abroad opportunities developed understandings about structural violence or intercultural competence concerning music teaching and learning. We describe …

No Sex Differences In Common Carotid Artery Stiffness Response Following Maximal Oxygen Consumption Test, Heysel Y. Morales, Michael Diaz, Zaria Opara, Allan Knox

International Journal of Exercise Science: Conference Proceedings

PURPOSE: Previous investigations have reported sex differences in the time course of age-related arterial stiffness, with postmenopausal women presenting increased risk of cardiovascular diseases. Using sex as a biological variable has identified differences between males and females in physiological responses to equivalent doses of exercise. The purpose of this study was to determine if sex differences exist in arterial stiffness response to a maximum oxygen consumption (VO2max) exercise test. METHODS: VO2max was measured by indirect calorimetry. Body composition was measured by air displacement plethysmography (BODPOD). Indices of common carotid artery (CCA) stiffness (Peterson’s elastic modulus [Ep], Beta stiffness [B1], …

Kinesiophobia Prevalence Among College Athletes, Lindsey R. Mcneely, Robert I. Dudley

International Journal of Exercise Science: Conference Proceedings

The fear avoidance model indicates that fear of re-injury and movement related fear (kinesiophobia) can foster avoidant behaviors leading to potentially injurious changes in movement. The Tampa Scale of Kinesiophobia (TSK-11), an 11-question survey, measures movement related fear. While much of the kinesiophobia literature has focused on individuals with chronic pain, there is little evidence on the prevalence of kinesiophobia among collegiate athletes, a population with high frequency of injury. What little evidence exists indicates a connection between high kinesiophobia and injurious movement patterns. PURPOSE: Given the lack of data on collegiate athletes, the purpose of this investigation is to …

A Comparison Of Heat Treatment-Induced Skeletal Muscle Adaptations Relative To Exercise Training, Jamie P. Kaluhiokalani, Jack Mehling, Brandon Pfeifer, Mohadeseh Ahmadi

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

In vitro and animal studies indicate that the response to heat stress is associated with beneficial adaptations that promote cell health and survival. Few studies to date have examined this finding in human subjects, and it is unclear how the adaptation compares in magnitude to exercise training. PURPOSE: To investigate the skeletal muscle adaptations (namely mitochondrial biogenesis and capillarization) of 6 weeks of deep-muscle heat treatment relative to exercise training. We hypothesized that heat treatment (HT), applied through pulsed shortwave diathermy (2 hr, 3 days/week) over a 6-week intervention period would lead to increased mitochondrial content and capillarity …

The Effects Of Exercise On Hunger And Satiety Hormone Concentrations Over A 36-Hour Fast: A Randomized Crossover Study, Jacob L. Coleman, Landon Deru, Hunter Chamberlain, Bruce W. Bailey

International Journal of Exercise Science: Conference Proceedings

Background: Feelings of hunger and satiation are known to be influenced physiologically through hormone secretion. Ghrelin (GH) is known as the primary “hunger” hormone, and GLP-1, PP, PYY, and C-Peptide (CP) are hormones known to signal feelings of satiety. The aim of this study was to assess hunger and satiety hormone production during a prolonged fast, and to evaluate how an initial bout of exercise influences this secretion. Subjective feelings of mood and hunger were also assessed throughout.

Methods: In this crossover study, 20 adult subjects (11 Male, 9 Female) completed two 36-hour fasts, with one protocol requiring the subject …

Evaluation And Utilization Of A Tall Fescue Germplasm Collection At Pergamino Inta, Argentina, B. S. Rosso, E. M. Pagano, P. Rimieri

IGC Proceedings (1977-2023)

One hundred and fifty four accessions of tall fescue (Festuca arundinacea Schreb.) representing different types grown around the world were evaluated at Pergamino Inta Experimental Station. A multivariate analysis was carried out to evaluate individual and group variations. Three principal components (PCs) explained 70 % of the variation. Cluster analysis (Ward method) allowed the identification of 7 groups of populations. Plants from the most promising populations were selected in order to form a new breeding gene pool. The main objective of this study is to develop a new cultivar with improved winter herbage yield. Selected genotypes were mostly of …

Effects Of Selection On Morphological Characteristics In Setaria Sphacelata (Schumach.) Moss, Liana Jank, Kenneth H. Quesenberry, P. Mislevy

IGC Proceedings (1977-2023)

Cattle production in Florida is limited by the lack of available warm-season forages adapted to the cool winters of the region. Setaria (S. sphacelata) has demonstrated green growth during cool conditions in subtropical climates around the world, and has the potential to fill this niche in cattle production in Florida. Four populations were selected in Gainesville and Ona, Florida: two cycles of selection for increased head number, one cycle for increased leaf width and one cycle for grazing tolerance. The objectives of this research were to compare these populations morphologically to determine changes due to selection. Selection for …

Correlated Evolution Of Distinct Signals Associated With Increased Social Selection In Female White-Shouldered Fairywrens, John Anthony Jones, Karan J. Odom, Ian R. Hoppe, Doka Nason, Serena Ketaloya, Jordan Karubian

School of Natural Resources: Faculty Publications

Conspicuous female signals have recently received substantial scientific attention, but it remains unclear if their evolution is the result of selection acting on females independently of males or if mutual selection facilitates female change. Species that express female, but not male, phenotypic variation among populations represents a useful opportunity to address this knowledge gap. White-shouldered fairywrens (Malurus alboscapulatus) are tropical songbirds with a well-resolved phylogeny where female, but not male, coloration varies allopatrically across subspecies. We explored how four distinct signaling modalities, each putatively associated with increased social selection, are expressed in two populations that vary in competitive pressure on …

Triumph Of The Commons: Sustainable Community Practices On Rapa Nui (Easter Island), Robert J. Dinapoli, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

The history of Rapa Nui (Easter Island) has long been framed as a parable for how societies can fail catastrophically due to the selfish actions of individuals and a failure to wisely manage common-pool resources. While originating in the interpretations made by 18th-century visitors to the island, 20th-century scholars recast this narrative as a “tragedy of the commons,” assuming that past populations were unsustainable and selfishly overexploited the limited resources on the island. This narrative, however, is now at odds with a range of archaeological, ethnohistoric, and environmental evidence. Here, we argue that while Rapa Nui did experience large-scale deforestation …

Ethanol And Opioids Do Not Act Synergistically To Depress Excitation In Carotid Body Type I Cells, Ryan J. Rakoczy, Kajal Kamra, Yoon-Jae Yi, Christopher N. Wyatt

Neuroscience, Cell Biology & Physiology Faculty Publications

The combination of opioids and ethanol can synergistically depress breathing and the acute ventilatory response to hypoxia. Multiple studies have shown that the underlying mechanisms for this may involve calcium channel inhibition in central neurons. But we have previously identified opioid receptors in the carotid bodies and shown that their activation inhibits calcium influx into the chemosensitive cells. Given that the carotid bodies contribute to the drive to breathe and underpin the acute hypoxic ventilatory response, we hypothesized that ethanol and opioids may act synergistically in these peripheral sensory organs to further inhibit calcium influx and therefore inhibit ventilation.

Changes In Histone H3 Acetylation On Lysine 9 Accompany Aβ 1-40 Overexpression In An Alzheimer’S Disease Yeast Model, Muna M. Hugais, Samantha N. Cobos, Seth A. Bennett, Jailene Paredes, Genevieve Foran, Mariana P. Torrente

Publications and Research

Alzheimer’s Disease (AD), the most common type of dementia, is a neurodegenerative disease characterized by plaques of amyloid-beta (Aβ) peptides found in the cerebral cortex of the brain. The pathological mechanism by which Aβ aggregation leads to neurodegeneration remains unknown. Interestingly, genetic mutations do not explain most AD cases suggesting that other mechanisms are at play. Epigenetic mechanisms, such as histone post-translational modifications (PTMs), may provide insight into the development of AD. Here, we exploit a yeast Aβ overexpression model to map out the histone PTM landscape associated with AD. We find a modest decrease in the acetylation levels on …

Vascular Endothelial Growth Factor A 165 Rescues Steroids, Inflammation And Follicle Arrest In High Androstenedione Cows, Mohamed A. Abedal-Majed, Shelby A. Springman, Courtney M. Sutton, Alexandria P. Snider, Brooke E. Bell, Mariah Hart, Scott G. Kurz, Jeffrey Bergman, Adam F. Summers, Renee M. Mcfee, John S. Davis, Jennifer R. Wood, Andrea S. Cupp

Department of Animal Science: Faculty Publications

A population of cows with excess androstenedione (A4; High A4) in follicular fluid, with follicular arrest, granulosa cell dysfunction, and a 17% reduction in calving rate was previously identified. We hypothesized that excess A4 in the ovarian microenvironment caused the follicular arrest in High A4 cows and that vascular endothelial growth factor A would rescue the High A4 phenotype. In trial 1, prior to culture, High A4 ovarian cortex (n=9) had greater numbers of early stage follicles (primordial) and fewer later-stage follicles compared to controls (n=11). Culture for 7 days did not relieve this follicular arrest; …

Reduction Of Cod And Highly Coloured Mature Landfill Leachate By Tin Tetrachloride With Rubber Seed And Polyacrylamide, Siti Fatihah Ramli, Hamidi Abdul Aziz, Fatehah Mohd Omar, Mohd Suffian Yusoff, Herni Halim, Mohamad Anuar Kamaruddin, Kamar Shah Ariffin, Yung-Tse Hung

Civil and Environmental Engineering Faculty Publications

Tin tetrachloride (SnCl4 ) as a coagulant and rubber seed (Hevea brasiliensis) (RS), and polyacrylamide (PAM) as the coagulant aid were investigated in this work to treat matured and stabilised landfill leachate rich in COD and colour. A standard jar test was conducted at different pH values and dosages of coagulant/coagulant aid. When SnCl4 acted as the primary coagulant, the optimum conditions occurred at pH 8 and 10,000 mg/L dosages, with 97.3% and 81% reductions of colour and COD, respectively. Both RS and PAM were not effective when used alone. When RS was used as the coagulant aid, the dosage …

High Rates Of Polygyny In Tropical Mexico Within The Native Range Of Vespula Squamosa., Alex K. Snyder, Kevin J. Loope

Honors College Theses

Polygyny, or the formation of colonies with multiple cooperating queens, has been observed in a variety of social Hymenoptera and likely exists as a convergent evolutionary strategy. Polygyne cooperation has been observed in several Vespula sp. and is correlated with a perennial social strategy. This perennial-polygyne behavior has been observed most commonly within the tropical and subtropical regions of the invasive Vespula pensylvanica and V. germanica, and rarely within their native temperate ranges. This phenomenon has been relatively undocumented within the tropical portions the V. squamosa native range, despite it being observed in their temperate ranges several times. We observed …

The focus will be upon one of the more recent versions AlphaZero but I hope to explain the core principles that allowed these algorithms to be so successful. I will generally refer to AlphaZero as theses [sic] core set of principles and will make it clear when I am referring to a specific algorithm of the AlphaGo family. AlphaZero in short combines Monte Carlo Tree Search (MCTS) with Deep learning and self-play. We will see how these …

Consumers' Perception Of Food Containing Insect Protein Affected By Serving Condition And Questionnaire Protocol, Yupeng Gao

LSU Master's Theses

Edible insects are a new sustainable protein source compared to meat. Western consumers show aversion to the prospect of insects as food due to unfamiliarity, food neophobia, and negative emotions. This dissertation research explored consumers’ emotional perception of insect-based food products presented under different testing conditions and examined the influence of other people’s emotional expressions towards consumers’ purchase decisions. To identify and rate emotion intensities, tests were conducted using three presenting formats including text, image, and an actual product; all of which were applied for both cookies containing insects and without insects. In addition to these presenting formats, news of …

Preventing Homelessness Among Veterans In Riverside County, California, Ashley Carroll

Selected Social Change Portfolios in Prevention, Intervention, and Consultation

An estimated 37,252 of the homeless population in the United States are veterans, 11,401 of which reside in the state of California (State, 2020). That’s 31% of the nations homeless veteran population residing in one state! Whats worse, every year this number is increasing. Many in need veterans are let down by the VA due to shortages of resources, funding, and long waitlists. Stigma, diversity, and and neglect are a few more issues behind this populations shortcomings. By focusing on prevention at an individual, family, community, and societal level, this population can receive the support it needs in order to …
