Evaluation Of A Nutritional Calming Supplement For Stress Management In Beef Cattle, Randall Mallette

LSU Master's Theses

Two studies were conducted to determine the efficacy of two formulations of a nutritional calming product, Placid 1.0 and Placid 2.0, at keeping beef cattle in a calm state when exposed to environmental factors that put them into an excited state. In the pilot study, nine crossbred beef heifers were orally drenched daily for three days with 60 mL of their respective treatments, pen scores and exit scores were recorded, and blood was collected for cortisol analysis. There were no treatment effects for either treatment on any of the measured behavioral parameters or serum cortisol concentrations.

The products were …

Molecular Identification Of Oomycete Species Associated With Woody Plants In Louisiana And Survey Of Oomycete Species Associated With Live Oak Trees Planted On The Louisiana State University Campus, Hamilton Crockett

LSU Master's Theses

Three Oomycetes genera, Phytophthora, Phytopythium and Pythium, contain many important plant pathogens. Historically, Phytophthora infestans, responsible for the great Irish potato famine, and Phytophthora ramorum, causal agent of sudden oak death disease, are the two better-known high impact pathogens. The LSU AgCenter Plant Diagnostic Center (PDC) has been isolating putative Phytophthora and related species from combined root and soil samples collected from various woody ornamentals and trees for over a decade. In August of 2016, Louisiana received torrential rains, which resulted in historic flooding in several southern parishes. During subsequent years, the PDC staff isolated a …

Interactive Effects Of The Partial Pressure Of Co2, Temperature, And Nutrient-Limitation On The Physiology And Growth Of The Coccolithophore E. Huxleyi Grown On A 12:12 L:D Cycle Of Illumination, James Bradley

LSU Master's Theses

I studied the interactive effects of pCO2, temperature, and nutrient limitation on the growth and physiology of the marine coccolithophore, Emiliania huxleyi. This was done to look at the effect of climate change factors on the widespread and abundant calcifying marine organism as a predictor of what the future has to hold. The strain of E. huxleyi (PnB 272 B10) was grown on a 12:12 L:D cycle of illumination and exposed to either high or low pCO2 under nutrient-replete or nitrate-limited conditions across a temperature range of 10–28C.

Impact Of Blood Flow Restricted Resistance Training On Skeletal Muscle Strength, Hypertrophy, Fatigue, Mitochondrial Response, And Activation, Brett Davis

LSU Doctoral Dissertations

Abstract

Blood flow restricted resistance exercise (BFR-RE) is a novel method that is effective at increasing strength and hypertrophy using much lower loads than the higher loads typical in progressive resistance exercise. However, the effects of BFR-RE on skeletal muscle fatigue, mitochondrial response, and activation are still being explored. This dissertation will discuss the impacts of BFR-RE, how it affects college-aged individuals that are trained and untrained, and the effects of BFR-RE on skeletal muscle fatigue, mitochondrial response, and activation.

The first study examined the effects of 6-weeks of low load blood flow restricted resistance exercise (LLBFR) on muscular strength, …

Regulation Of Nucleotide Excision Repair, Wenzhi Gong

LSU Doctoral Dissertations

Nucleotide excision repair (NER), a “cut and patch” mechanism, has two subpathways, namely transcription coupled repair (TCR) and global genome repair (GGR). TCR rapidly removes UV photoproduct (UV PP) in the transcribed strand (TS) of an actively transcribed gene, whereas GGR removes those DNA lesions throughout the genome. This dissertation mainly focused on identifying novel factors that function in NER and investigating the potential molecular mechanisms underlying initial damage recognition and downstream processes in NER. We identified Rpb7, a subunit of RNA polymerase II, represses TCR via its multiple regions. Specifically, the conserved region of Rpb7 that interacts with the …

Differences In Plant Hormone Responses Between Arabidopsis Thaliana And Schrenkiella Parvula Facing Lithium Toxicities, Jifeng Li

LSU Doctoral Dissertations

Investigating stress responses in plants is central to plant development studies and crop research. Identifying mechanisms of plant abiotic stress tolerance and adaptation will be keys to relieve the conflict between an increasing global population and declining agronomic land. Studies on extremophytes and their genetic responses to environmental stress are a way to help understand how and why these extremophile plants can develop well under extreme environments including high salinity and heavy metal toxicity. The studies herein first focus on comparative responses at the genetic level to lithium toxicity between Arabidopsis thaliana and Schrenkiella parvula. Based on elemental quantification …

Year-Round Weather Alters Nest-Provisioning Rates In A Migratory Owl, Eliza D. Stein, Stephen R. Midway, Brian D. Linkhart

Faculty Publications

As global temperatures and precipitation become more extreme, habitat specialists are at particular risk of being pushed past their environmental tolerance limits. Flammulated Owls (Psiloscops flammeolus) are small migratory owls that breed in temperate conifer forests of western North America. Their highly specialized nesting and foraging requirements make them indicators of ecosystem health. Using 17 years of nest observations, we investigated how annual weather patterns affected Flammulated Owl nesting and foraging behaviors during the breeding season. We used generalized linear models with a changepoint parameter to evaluate nest provisioning and nestling growth rates in years of extreme temperature and precipitation. …

Evidence For Two Soybean Looper Strains In The United States With Limited Capacity For Cross-Hybridization, Rodney N. Nagoshi, Jeffrey A. Davis, Robert L. Meagher, Fred R. Musser, Graham P. Head, Hector Portillo, Henry Teran

Faculty Publications

The noctuid moth soybean looper (SBL), Chrysodeixis includens (Walker) is an economically important pest of soybeans (Glycine max (L.) Merr.) in the southeastern United States. It has characteristics that are of particular concern for pest mitigation that include a broad host range, the capacity for annual long-distance flight, and resistance in some populations to important pesticides such as pyrethroids and chitin synthesis inhibitor. The biology of SBL in the United States resembles that of the fellow noctuid fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), a major pest of corn and several other crops. FAW exhibits a population structure in that …

Investigating The Migratory Behavior Of Soybean Looper, A Major Pest Of Soybean, Through Comparisons With The Corn Pest Fall Armyworm Using Mitochondrial Haplotypes And A Sex-Linked Marker, Rodney N. Nagoshi, Jeffrey A. Davis, Robert L. Meagher, Fred R. Musser, Graham P. Head, Hector Portillo, Henry Teran

Faculty Publications

The Noctuid moth soybean looper (SBL), Chrysodeixis includens (Walker), is an economically important pest of soybean (Glycine max (Linnaeus) Merrill). Because it is not known to survive freezing winters, permanent populations in the United States are believed to be limited to the southern regions of Texas and Florida, yet its geographical range of infestations annually extend to Canada. This indicates annual migrations of thousands of kilometers during the spring and summer growing season. This behavior is like that of the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), also a Noctuid that is a major global pest of corn. SBL and …

Clathrin-Mediated Endocytosis Facilitates The Internalization Of Magnaporthe Oryzae Effectors Into Rice Cells, Ely Oliveira-Garcia, Tej Man Tamang, Jungeun Park, Melinda Dalby, Magdalena Martin-Urdiroz, Clara Rodriguez Herrero, An Hong Vu, Sunghun Park, Nicholas J. Talbot, Barbara Valent

Faculty Publications

Fungi and oomycetes deliver effectors into living plant cells to suppress defenses and control plant processes needed for infection. Little is known about the mechanism by which these pathogens translocate effector proteins across the plasma membrane into the plant cytoplasm. The blast fungus Magnaporthe oryzae secretes cytoplasmic effectors into a specialized biotrophic interfacial complex (BIC) before translocation. Here, we show that cytoplasmic effectors within BICs are packaged into punctate membranous effector compartments that are occasionally observed in the host cytoplasm. Live cell imaging with fluorescently labeled proteins in rice (Oryza sativa) showed that these effector puncta colocalize with the plant …

A Cyclical Phenomenon Among Stock & Commodity Markets, Hector O. Zapata, Junior E. Betanco, Maria Bampasidou, Michael Deliberto

Faculty Publications

Considerable studies have examined the relationship between commodity markets and stock markets. This paper studies the cyclical relationship between commodity markets and stock markets with implications for investing based on index relationships. Stock markets are represented by the U.S. S&P 500 index and aggregate commodity markets by the U.S. producer price index (PPI). Tradeable market indexes readily available to investors, namely the S&P GSCI Index and the Bloomberg Commodity Index (BCOM), are also studied. An optimal bandpass filter is used to estimate the cyclical component using a pricing-performance measure of the S&P 500 relative to the PPI, based on annual …

Transgenic corn and cotton that produce Cry and Vip3Aa toxins derived from Bacillus thuringiensis (Bt) are widely planted in the United States to control lepidopteran pests. The sustainability of these Bt crops is threatened because the corn earworm/bollworm, Helicoverpa zea (Boddie), is evolving a resistance to these toxins. Using Bt sweet corn as a sentinel plant to monitor the evolution of resistance, collaborators established 146 trials in twenty-five states and five Canadian provinces during 2020–2022. The study evaluated overall changes in the phenotypic frequency of resistance (the ratio of larval densities in Bt ears relative to densities in non-Bt ears) …

Large Uncertainties In Co2 Water–Air Outgassing Estimation With Gas Exchange Coefficient Kt For A Large Lowland River, Anamika Dristi, Y. Jun Xu

Faculty Publications

Aquatic CO2 emission is typically estimated (i.e., not measured) through a gas exchange balance. Several factors can affect the estimation, primarily flow velocity and wind speed, which can influence a key parameter, the gas exchange coefficient KT in the balancing approach. However, our knowledge of the uncertainty of predictions using these factors is rather limited. In this study, we conducted a numeric assessment on the impact of river flow velocity and wind speed on KT and the consequent CO2 emission rate. As a case study, we utilized 3-year (2019–2021) measurements on the partial pressure of dissolved carbon dioxide (pCO2) in …

Substantially Enhanced Landscape Carbon Sink Due To Reduced Terrestrial-Aquatic Carbon Transfer Through Soil Conservation In The Chinese Loess Plateau, Lishan Ran, Nufang Fang, Xuhui Wang, Shilong Piao, Chun Ngai Chan, Siliang Li, Yi Zeng, Zhihua Shi, Mingyang Tian, Yi Jun Xu, Junyu Qi, Boyi Liu

Faculty Publications

Soil conservation is of global importance, as accelerated soil erosion by human activity is a primary threat to ecosystem viability. However, the significance and role of soil conservation in reshaping landscape carbon (C) accounting has not been comprehensively integrated in the terrestrial C sink. Here, we present the first integrated assessment of the modified terrestrial C sink and aquatic C transport due to soil conservation for the semiarid Chinese Loess Plateau (CLP), the world's most vulnerable region to soil erosion. We show a surprisingly low terrestrial-aquatic C transfer that offset the terrestrial net ecosystem productivity by only 7.5%, which we …

Current Discoveries And Future Implications Of Eating Disorders, Bing Feng, Jerney Harms, Emily Chen, Peiyu Gao, Pingwen Xu, Yanlin He

Division of Basic Science Faculty Publications

Eating disorders (EDs) are characterized by severe disturbances in eating behaviors and can sometimes be fatal. Eating disorders are also associated with distressing thoughts and emotions. They can be severe conditions affecting physical, psychological, and social functions. Preoccupation with food, body weight, and shape may also play an important role in the regulation of eating disorders. Common eating disorders have three major types: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). In some cases, EDs can have serious consequences for an individual’s physical and mental health. These disorders often develop during adolescence or early adulthood and affect …

Long-Term Capture Data Uncover Shifts In The Daily Activity Patterns Of Amazonian Birds, Cameron L. Rutt, Philip C. Stouffer, Bruna R. Amaral, David A. Luther

Faculty Publications

Although the duration of biological rhythms varies from milliseconds to decades, daily cycles are especially widespread for individual organisms. These circadian rhythms are synchronized by light–dark cycles, which govern predictable changes in other microclimate variables. Despite the fixed, regular nature of these abiotic cycles at low latitudes, little is known about how different animals structure activity along these gradients. We used 25 years of capture–recapture data and ~ 25 000 unique captures to characterize ‘activity' (time of capture) for 65 species of Amazonian birds in the lowest forest stratum (0–2.5 m). To quantify vertical niche breadths, we also measured foraging …

Measuring In Vivo Adipose Tissue Kinetics In Humans Using The Deuterium (2h)-Labeling Approach, Dereck Kibodeaux, Jonathan Savoie, Eric Ravussin, Mark Fitch, Marc K. Hellerstein, Ursula White

Clinical Research Faculty Publications

White adipose tissue is a highly plastic organ that is necessary to maintain whole-body energy homeostasis. The adipose tissue mass and changes in the fat mass or distribution are regulated by changes in the synthesis and breakdown (i.e., turnover) of adipose cells and triacylglycerols. Evidence suggests that the manner and magnitude of subcutaneous adipose tissue expansion (i.e., hypertrophy vs. hyperplasia) and turnover can influence metabolic health, as adipogenesis has been implicated in the pathogenesis of obesity and related diseases. Despite the potential role of adipose turnover in human health, there is a lack of knowledge about the in vivo kinetics …

Extensive Independent Amplification Of Platy-1 Retroposons In Tamarins, Genus Saguinus, Jessica M. Storer, Jerilyn A. Walker, Thomas O. Beckstrom, Mark A. Batzer

Faculty Publications

Platy-1 retroposons are short interspersed elements (SINEs) unique to platyrrhine primates. Discovered in the common marmoset (Callithrix jacchus) genome in 2016, these 100 bp mobile element insertions (MEIs) appeared to be novel drivers of platyrrhine evolution, with over 2200 full-length members across 62 different subfamilies, and strong evidence of ongoing proliferation in C. jacchus. Subsequent characterization of Platy-1 elements in Aotus, Saimiri and Cebus genera, suggested that the widespread mobilization detected in marmoset (family Callithrichidae) was perhaps an anomaly. Two additional Callithrichidae genomes are now available, a scaffold level genome assembly for Saguinus imperator (tamarin; SagImp_v1) and a chromosome-level assembly …

Vcp Promotes Ttaf-Target Gene Expression And Spermatocyte Differentiation By Downregulating Mono-Ubiquitylated H2a, Tyler J. Butsch, Olga Dubuisson, Alyssa E. Johnson, K. Adam Bohnert

Faculty Publications

Valosin-containing protein (VCP) binds and extracts ubiquitylated cargo to regulate protein homeostasis. VCP has been studied primarily in aging and disease contexts, but it also affects germline development. However, the precise molecular functions of VCP in the germline, particularly in males, are poorly understood. Using the Drosophila male germline as a model system, we find that VCP translocates from the cytosol to the nucleus as germ cells transition into the meiotic spermatocyte stage. Importantly, nuclear translocation of VCP appears to be one crucial event stimulated by testis-specific TBP-associated factors (tTAFs) to drive spermatocyte differentiation. VCP promotes the expression of several …

Medical Libraries And Their Complicated Past: An Exploration Of The Historical Connections Between Medical Collections And Racial Science, Raymond Pun, Patrice R. Green, Nicollette Davis

Faculty Publications

For over a millennium, libraries and library workers have advanced the knowledge of human science by building, preserving, and sharing collections and research. Historically, libraries have also aligned their institutional responsibilities to adhere to and support the values and virtues of oppressive and colonial practices. Library history has shown the mistreatments and denials of information access of marginalized groups. The history of libraries in the health and medical sciences reveals how these institutions and their workers have preserved and circulated research studies perpetuating racial science. This commentary highlights how such institutions shape and contribute to racial science in the field …

Effects Of Alkylation On Potency Of Benz[A]Anthracene For Ahr2 Transactivation In Nine Species Of Freshwater Fish, Justin Dubiel, Hunter Johnson, Andreas N.M. Eriksson, A. Hontela, Jon A. Doering, Steve Wiseman

Faculty Publications

Polycyclic aromatic hydrocarbons (PAHs) are naturally occurring or anthropogenic organic chemicals that can activate the aryl hydrocarbon receptor 2 (AhR2) and induce toxicity in fishes. Alkyl PAHs are more abundant than nonalkylated PAHs in certain environmental matrices and there is growing evidence that alkylation can increase potency, dependent on the position of alkylation. However, it is unknown if the effect of alkylation on potency is conserved across species. In addition, relatively little is known regarding the extent of interspecies variation in sensitivity to PAHs and alkyl PAHs. Therefore, objectives of the present study were to characterize potency of benz[a]anthracene (BAA) …
