Leptin Receptor Signaling Is Required For Intact Hypoglycemic Counterregulation: A Study In Male Zucker Rats, Christopher D. Morrison, Marina A. Duvall, Cristal M. Hill, Redin A. Spann, David H. Mcdougal Oct 2021

Leptin Receptor Signaling Is Required For Intact Hypoglycemic Counterregulation: A Study In Male Zucker Rats, Christopher D. Morrison, Marina A. Duvall, Cristal M. Hill, Redin A. Spann, David H. Mcdougal

Division of Basic Science Faculty Publications

Hypoglycemia is a major barrier to clinical management of persons with diabetes. Emerging evidence supports a role for leptin in gating hypoglycemic counterregulation. This work demonstrates that male leptin receptor null, Zucker (fa/fa), rats display severe impairments in hypoglycemic counterregulation. Thus, augmenting leptin levels may have clinical utility for preventing hypoglycemia.

Mitochondria undergo continuous cycles of fission and fusion to promote inheritance, regulate quality control, and mitigate organelle stress. More recently, this process of mitochondrial dynamics has been demonstrated to be highly sensitive to nutrient supply, ultimately conferring bioenergetic plasticity to the organelle. However, whether regulators of mitochondrial dynamics play a causative role in nutrient regulation remains unclear. In this study, we generated a cellular loss-of-function model for dynamin-related protein 1 (DRP1), the primary regulator of outer membrane mitochondrial fission. Loss of DRP1 (shDRP1) resulted in extensive ultrastructural and functional remodeling of mitochondria, characterized by pleomorphic enlargement, increased electron density of …

Isotopic Fingerprints Of Mountain Uplift And Global Cooling In Paleoclimatic And Paleoecological Records From The Northern Tibetan Plateau, Mingqiu Hou, Guangsheng Zhuang, Minghao Wu

Faculty Publications

Post-middle Miocene changes in climate and ecology in the northern Tibetan Plateau have been attributed to tectonic uplift and global climate change. However, the relative roles of tectonism and global climate change have been a long-standing debate. To untangle the complex influences of global climate change versus the tectonism on regional climate and ecology in the northern Tibetan Plateau, we studied carbon isotopes (δ13Cwax) of leaf wax long-chain n-alkanes and carbon (δ13C) and oxygen isotopes (δ18O) of carbonates from three stratigraphic successions (ca. 16 Ma to 2 Ma) in the Hexi Corridor (foreland basin) …

Multifunctional Corrosion Control System As A Sustainable Approach For Reinforced Concrete Elements, Homero Castaneda, Miladin Radovic, Brendy Rincon, Oladis Troconis, Arturo Montoya, Changkyu Kim, Loreto Dacio

Publications

Corrosion inhibitors can be utilized to decrease the corrosion kinetics and therefore increase the durability of reinforced concrete structures. Recently, a green synthesized organic compound, 1-benzyl-4-phenyl-1H-1,2,3-triazole (BPT), was shown to be a successful green organic corrosion inhibitor for mild steel. Studies suggested that the BPT adsorbs chemically onto the steel and acts as a mixed inhibitor, suppressing both the anodic and cathodic corrosion kinetics of steel. In addition, microcapsules have shown to be an efficient way for a controlled inhibitor release in reinforced concrete structures. On the other hand, geopolymers (GPs) comprised of a long range of covalently bonded alumino-silicates, …

The rapid and widespread evolution of fungicide resistance remains a challenge for crop disease management. The demethylation inhibitor (DMI) class of fungicides is a widely used chemistry for managing disease, but there has been a gradual decline in efficacy in many crop pathosystems. Reliance on DMI fungicides has increased resistance in populations of the plant pathogenic fungus Cercospora beticola worldwide. To better understand the genetic and evolutionary basis for DMI resistance in C. beticola, a genome-wide association study (GWAS) and selective sweep analysis were conducted for the first time in this species. We performed whole-genome resequencing of 190 C. beticola …

Corpse management is essential for social animals to maintain colony health. In the eastern subterranean termite, Reticulitermes flavipes, workers carry out undertaking behaviors to mitigate the risks associated with the dead. In this study, we hypothesized that termites would respond differently to the corpses from different castes based on their postmortem chemical signatures. To test this hypothesis, we 1) documented the behavioral responses of the workers toward corpses from different castes, and 2) profile the chemical signatures of these corpses. Corpses from all castes were retrieved inside the nests and cannibalized when they were decomposed <64 >h, regardless of the presence …

Eating Behaviors And Dietary Patterns Of Women During Pregnancy: Optimizing The Universal ‘Teachable Moment’, Maryam Kebbe, Emily W. Flanagan, Joshua R. Sparks, Leanne M. Redman

Clinical Research Faculty Publications

Understanding women’s perceptions of eating behaviors and dietary patterns can inform the ‘teachable moment’ model of pregnancy. Our objectives were to describe eating behaviors and dietary patterns in pregnancy. This was a cross‐sectional, national electronic survey. Women were ≥18 years of age, living in the United States, currently pregnant or less than two years postpartum, and had internet access. Age, education, race, and marriage were included as covariates in ordinal and binary logistic regressions (significance p < 0.05). Women (n = 587 eligible) made positive or negative changes to their diets, while others maintained pre‐existing eating behaviors. The majority of women did not try (84.9 to 95.1% across diets) and were unwilling to try (66.6 to 81%) specific dietary patterns during pregnancy. Concerns included not eating a balanced diet (60.1 to 65.9%), difficulty in implementation without family (63.2 to 64.8%), and expense (58.7 to 60.1%). Helpful strategies included being provided all meals and snacks (88.1 to 90.6%) and periodic consultations with a dietitian or nutritionist (85 to 86.7%). Responses differed across subgroups of parity, body mass index, and trimester, notably in women with obesity who reported healthier changes to their diet (p < 0.05). Our study underscores the importance of tailoring care early to individual needs, characteristics, and circumstances.


Cage's Imitation Game: Cheap Imitation And Song Books Through The Sketches, Jeffrey Perry Sep 2021

Cage's Imitation Game: Cheap Imitation And Song Books Through The Sketches, Jeffrey Perry

Faculty Publications

The theme of John Cage’s Song Books (1970), according to Cage, is contained in the statement “We connect Satie with Thoreau” (Cage 1970a, 1). Previous studies of Cage’s Song Books have not asked what I feel to be obvious questions: how, precisely, does Cage connect Satie with Thoreau? To what end? And how does Cage connect to Satie and Thoreau (and to the other sources from which he borrows)? I make use of Cage’s sketch materials to seek answers. I examine three of the Solos for Voice from Song Books that make use of the cheap-imitation procedure that Cage had …

An Examination Of Retail-Level Purchasing Behavior For Healthful Food In Louisiana, Marcus Coleman

LSU Doctoral Dissertations

Consumer access and choice for quality and affordable healthful foods at the retail-level is at the forefront of discussions related to the nutritional status of consumers in many communities across the United States. In Louisiana, many consumers live in food environments where retail options for quality and affordable healthful foods are limited, not affordable, or not available. Addressing these issues is complicated by the fact that literature focused on consumer access and choice for healthful foods at the retail-level in Louisiana is inadequate to play a significant role in addressing issues related to purchasing behavior for healthful foods faced by …


Engineering The Surface Of Fe3o4 Nanoparticles For Catalytic And Magnetic Applications, Natalia Da Silva Moura Aug 2021

Engineering The Surface Of Fe3o4 Nanoparticles For Catalytic And Magnetic Applications, Natalia Da Silva Moura

LSU Doctoral Dissertations

With the rapid depletion of the U.S. energy resources coupled with population growth, heat management technologies must be improved to sustain our quality of life. Precisely, in catalysis, it is estimated that only ~50% of the energy supplied to the reactor is used for product conversion due to dissipation losses. Among the emerging technologies with a promising reduction in heat losses is induction heating, offering targeted heat delivery with magnetic nanoparticles. Under alternating magnetic fields (AMF), these nanoparticles can absorb the energy from Radio-Frequency (RF) fields and dissipate it as heat on the nanoparticle surface. This in situ heat generation …


Understanding The Etiology Of Taproot Decline Of Soybean Caused By Xylaria Necrophora, José E. Ortiz Solórzano Aug 2021

Understanding The Etiology Of Taproot Decline Of Soybean Caused By Xylaria Necrophora, José E. Ortiz Solórzano

LSU Master's Theses

Taproot decline (TRD) of soybean is caused by Xylaria necrophora. However, the mechanisms by which it infects soybean and produces symptoms are unknown. Symptoms of TRD include foliar interveinal chlorosis and necrosis and root necrosis, yet X. necrophora appears to be restricted to the roots. While Xylaria species are predominantly wood decomposers, a few are pathogens. More importantly, they produce secondary metabolites (SMs) with multiple bioactivities, including phytotoxicity and antimicrobial activity. Preliminary experiments suggested that X. necrophora was producing SMs responsible for TRD symptoms. We evaluated cell-free culture filtrates (CFs) for phytotoxicity on soybeans, testing for changes in chlorophyll …

Three Learning Contexts As Paths To Preservice Instrumental Music Teachers' Score Analysis, Rehearsal Planning, And Instructional Readiness: An Exploratory Study In Professional Development, Jennifer Lee Pulling

LSU Doctoral Dissertations

Despite an abundance of evidence-based research pointing to the effectiveness of long-term teacher professional development (PD) (Darling-Hammond, Hyler & Gardner, 2017; Desimone, 2009), instrumental music teachers who seek to improve their teaching practices are limited to and often prefer short-term PD opportunities (Bauer, 2007; West, 2020). In recent years, a growing knowledge base focused on music teacher PD has given attention to long-term, content-based and collaborative music PD (Conway, 2015; Kastner, 2014; Stanley, Snell & Edgar, 2014) while a dearth of evidence-based research exists on short-term music PD (Bauer, 2007; West, 2020). The purpose of this collective case study was …

Indicators Of Senescence And Their Relationship With The Antioxidant Response Element In Ovarian Cancer Cells—Toward A More Encompassing View Of Enzyme Activity Levels In Cells, Shaniqua Analycia Hayes

LSU Doctoral Dissertations

Enzymes and other related proteins are promising targets as biomarkers for cancer diagnostics, and it is therefore important to be able to quantify intracellular enzyme activity levels, not just presence of enzyme. Thus, there is a great need for the development of methods that offer spatiotemporal quantification of intracellular enzyme activity levels in respiring 2- and 3-dimensional cultures or their sample-processed variants. Previous studies have demonstrated that ß-gal is upregulated in senescence and in select ovarian cancers, and its expression/activity is upregulated when cells are under oxidative stress conditions. To that end, the primary goal of this work was to …


Learning To Interpret Fluid Type Phenomena Via Images, Simron Thapa Aug 2021

Learning To Interpret Fluid Type Phenomena Via Images, Simron Thapa

LSU Doctoral Dissertations

Learning to interpret fluid-type phenomena via images is a long-standing challenging problem in computer vision. The problem becomes even more challenging when the fluid medium is highly dynamic and refractive due to its transparent nature. Here, we consider imaging through such refractive fluid media like water and air. For water, we design novel supervised learning-based algorithms to recover its 3D surface as well as the highly distorted underground patterns. For air, we design a state-of-the-art unsupervised learning algorithm to predict the distortion-free image given a short sequence of turbulent images. Specifically, we design a deep neural network that estimates the …

High-entropy alloys (HEAs) have intriguing material properties, but their potential as catalysts has not been widely explored. Based on a concise theoretical model, we predict that the surface of a quaternary HEA of base metals, CoCrFeNi, should go from being nearly fully oxidized except for pure Ni sites when exposed to O2 to being partially oxidized in an acidic solution under cathodic bias, and that such a partially oxidized surface should be more active for the electrochemical hydrogen evolution reaction (HER) in acidic solutions than all the component metals. These predictions are confirmed by electrochemical and surface science experiments: the …
