Fibrogenesis And Adipogenesis In Farm Animals And Rodents, Chaoyang Li

LSU Doctoral Dissertations

In this dissertation, we aimed to provide additional insight into the mechanisms of fibrogenesis and adipogenesis based on different animal models to help the discovery of new treatments in cardiovascular disease, beef breeding strategies, and feed nutrition modifications.

Wayu, the Japanese Black cow, are well-known for their high IMF content, while the Brahman cattle have much less marbling. The development of IMF correlated with the increase in the size and number of IMF adipocytes, which have identified to be derived from a group of progenitor cells known as fibro/adipogenic progenitor (FAP) cells because of their bipotent differentiation ability. Interestingly, the …

Elgin's "Native Tongue": A "Me Too" Universe?, Amir Barati

Tête à Tête: Journal of Francophone Studies

Suzette Haden Elgin’s novel Native Tongue (1984) provides a fascinating critique of the ideologies inscribed into patriarchal language and evokes an extremely valuable linguistic and political awareness. This article will examine the liability of the ways the novel revolts against the patriarchal society via the introduction of a gynocentric linguistic intervention. I claim, Elgin’s novel showcases an invaluable instance of how it is possible for women to revolt against the pillars of patriarchy through manipulations at the gestalt and schematic level of language and most specifically, the bodily metaphoric quality of the English. This proposed transformation of the schematic and …

Transgressing Boundaries Of Identity, Geography And Time In Transmutadxos And La Mucama De Omicunlé, Lucinda Smith

Tête à Tête: Journal of Francophone Studies

The literary works of Rita Indiana (1977) and Yolanda Arroyo Pizarro (1970) are recognised for exposing and challenging hegemonic ideas of identity, sexuality and power. The transgression of boundaries appears time and again in the fiction of both writers, whether these be boundaries of sexual or gender identity, desire, geography, time or even life and death. Using Rita Indiana’s novel La mucama de Omicunlé (2015) and Arroyo’s collection of short stories Transmutadxs (2016), the authors’ representations of such transgressions are the focus of this essay.

Further to addressing similar themes in their texts, both Rita Indiana and Arroyo Pizarro were …

Writing Desire On The Lesbian Body: Baudelaire’S Fantasies And Vivien’S Realities, Emily Wieder

Tête à Tête: Journal of Francophone Studies

In The Flowers of Evil [Les Fleurs du Mal (1857)], French poet Charles Baudelaire paints three female bodies: the mistress, the prostitute, and the lesbian. The latter appears in three of one-hundred poems but so captivated Baudelaire that he almost titled the collection The Lesbians. Censors nevertheless condemned the anthology and suppressed two of the lesbian poems. The remaining lesbian poem compares the “damned women” to “thoughtful cattle.” A rare representation of lesbian bodies, this metaphor problematically depicts them as savage.

Yet this “Other” exemplifies the baudelairean poetic ideal. By crafting Beauty, the Poet immortalizes his corpus. As the …

Pharos The Egyptian And The Gothic Other As Excess, Shruti Jain, Kaushik Tekur Venkata

Tête à Tête: Journal of Francophone Studies

Guy Boothby’s Pharos the Egyptian, published in 1889, employs the category of the Gothic to discuss various anxieties plaguing the late Victorian society. It deals with issues such as the Gothic Other’s ‘magical’ capabilities, revenge, disease, and the colonial extraction of wealth, among others. The novel overwhelms the binary between the rational European self and the Gothic colonial other by presenting the Egyptian Pharos not as an opposite but as an excess of the European self. Pharos is as rational as he is Gothic and in this excess of being both, he destabilizes the hierarchy and binary at once. …

Design And Fabrication Of A Low-Cost, Portable, Battery-Operated Surface Enhanced Raman Scattering (Sers) Optical Device, Blessing Adewumi

LSU Doctoral Dissertations

Raman Spectroscopy is a time-honored, non-invasive method for analyzing and identifying the molecular composition of materials. However, unenhanced Raman Spectroscopy has extremely low sensitivity which limits its sensing capability. SERS brings rough nano-metallic surfaces in contact with the material molecules to enormously enhance the Raman signals.

The sensitivity of SERS can be exploited in probe applications where the spectrometer needs to be brought near the specimen. For example, a long optical fiber coupled to a SERS device can be used to characterize and identify easy-to-reach cancerous tissues in organisms. Unfortunately, background signals in a long fiber can easily mask any …

The Influence Of Perceived Realistic And Symbolic Threat On College Students’ Attitudes Toward Immigrants And Immigration, Brook Shantel Spurlock

LSU Doctoral Dissertations

Immigration has been one of the most dominant and salient political issues during recent presidential election. Unfortunately, the debates surrounding immigration often castigated Latin Americans as threatening, with the intent to spark fear among voters, while increasing the support for anti-immigration policies, such as the border wall and opposition to passage of a law granting citizenship to Dreamers. The purpose of this dissertation was to determine how realistic and symbolic threats influence college students’ attitudes on immigrants and immigration. Very few studies have been conducted on how realistic and symbolic threats influence immigration attitudes and opinions regarding a wide range …

Designing A Clinical Study With Dietary Supplements: It's All In The Details, Z. Elizabeth Floyd, David M. Ribnicky, Ilya Raskin, Daniel S. Hsia, Jennifer C. Rood, Bill J. Gurley

Division of Basic Science Faculty Publications

A successful randomized clinical trial of the effect of dietary supplements on a chosen endpoint begins with developing supporting data in preclinical studies while paying attention to easily overlooked details when planning the related clinical trial. In this perspective, we draw on our experience studying the effect of an ethanolic extract from Artemisia dracunculus L. (termed PMI-5011) on glucose homeostasis as a potential therapeutic option in providing resilience to metabolic syndrome (MetS). Decisions on experimental design related to issues ranging from choice of mouse model to dosing levels and route of administration in the preclinical studies will be discussed in …

Reef Sediments Can Act As A Stony Coral Tissue Loss Disease Vector, Michael S. Studivan, Ashley M. Rossin, Ewelina Rubin, Nash Soderberg, Daniel M. Holstein, Ian C. Enochs

Faculty Publications

Stony coral tissue loss disease (SCTLD) was first observed in 2014 near Virginia Key in Miami-Dade County, Florida. Field sampling, lab experiments, and modeling approaches have suggested that reef sediments may play a role in SCTLD transmission, though a positive link has not been tested experimentally. We conducted an ex situ transmission assay using a statistically-independent disease apparatus to test whether reef sediments can transmit SCTLD in the absence of direct contact between diseased and healthy coral tissue. We evaluated two methods of sediment inoculation: batch inoculation of sediments collected from southeast Florida using whole colonies of diseased Montastraea cavernosa, …

Current Methods And Future Directions In Avian Diet Analysis, Brandon D. Hoenig, Allison M. Snider, Anna M. Forsman, Keith A. Hobson, Steven C. Latta, Eliot T. Miller, Michael J. Polito, Luke L.

Faculty Publications

Identifying the composition of avian diets is a critical step in characterizing the roles of birds within ecosystems. However, because birds are a diverse taxonomic group with equally diverse dietary habits, gaining an accurate and thorough understanding of avian diet can be difficult. In addition to overcoming the inherent difficulties of studying birds, the field is advancing rapidly, and researchers are challenged with a myriad of methods to study avian diet, a task that has only become more difficult with the introduction of laboratory techniques to dietary studies. Because methodology drives inference, it is important that researchers are aware of …

Women Of Power: Mapping The Spiritual Journeys Of Caribbean Women Across Regional Fiction As Portrayed In The Book Of Night Women, Texaco, And Erzulie's Skirt, Natalie Sandy D'Auvergne-Lamotte

LSU Doctoral Dissertations

Contemporary Caribbean fiction serves as an active agent for refining and expanding definitions of Caribbeanness. This study aims at demonstrating how Caribbean writers use representations of Caribbean women to contribute to an opaquer regional vision that argues against homogenizing ideas of Caribbeanness. The Book of Night Women, Texaco, and Erzulie’s Skirt, respectively written by Marlon James (Jamaica), Patrick Chamoiseau (Martinique), and Anna-Maurine Lara (Dominican Republic), work by making space for more historically accurate and locally representative images of Caribbeanness through the Caribbean women they portray. Though characters live on different islands (at different times), they still manage to represent …

Isocaloric Low Protein Diet In A Mouse Model For Vanishing White Matter Does Not Impact Isr Deregulation In Brain, But Reveals Isr Deregulation In Liver, Lisanne E. Wisse, Denise Visser, Timo J. Ter Braak, Abdellatif Bakkali, Eduard A. Struys, Christopher D. Morrison, Marjo S. Van Der Knaap, Truus E.M. Abbink

Division of Basic Science Faculty Publications

Objective: Vanishing white matter (VWM) is a genetic brain white matter disorder caused by mutations in eIF2B. eIF2B is central in the integrated stress response (ISR), during which its activity is inhibited by various cellular stresses. VWM is a chronic progressive disease with episodes of rapid neurological deterioration provoked by stresses. VWM patients and VWM mouse models show ISR deregulation in brain, correlating with chronic disease development. ISR inhibition ameliorates the chronic disease in VWM mice. The subacute deteriorations have not been modeled yet. We hypothesized that ISR activation could worsen disease progression in mice and model the episodic neurological …

Obesity: Understanding And Achieving A Healthy Weight, George A. Bray, Catherine M. Champagne

Population and Public Health Science Faculty Publications

Obesity is a chronic, relapsing, stigmatized disease process that is increasing in prevalence, affecting both adults and children. It is the result of a small positive energy imbalance from too much food or too little activity. These underlying causes are influenced by many environmental factors. The food we eat is more than “calories,” and focusing on calories alone may not be as productive as focusing on patterns of eating and the role of sugar and fat in the diet. Obesity increases the risk of many diseases and shortens life span, and weight loss provides benefits in reducing health risks and …

Faculty Publications

Parastagonospora nodorum is an economically important necrotrophic fungal pathogen of wheat. Parastagonospora nodorum secretes necrotrophic effectors that target wheat susceptibility genes to induce programmed cell death (PCD). In this study, we cloned and functionally validated SnTox5 and characterized its role in pathogenesis. We used whole genome sequencing, genome-wide association study (GWAS) mapping, CRISPR-Cas9-based gene disruption, gain-of-function transformation, quantitative trait locus (QTL) analysis, haplotype and isoform analysis, protein modeling, quantitative PCR, and laser confocal microscopy to validate SnTox5 and functionally characterize SnTox5. SnTox5 is a mature 16.26 kDa protein with high structural similarity to SnTox3. Wild-type and mutant P. nodorum strains …

A New Detection Of The Invasive Mexican Rice Borer (Lepidoptera: Crambidae) From Georgia In The United States Based On Morphological And Molecular Data, Ilgoo Kang, Blake Wilson, Blake Carter, Rodrigo Diaz

Faculty Publications

The Mexican rice borer, Eoreuma loftini (Dyar), is an invasive herbivore that attacks many gramineous host plants. The species is an economic pest of several grass crops in North America including sugarcane (Saccharum spp.), rice (Oryza sativa), corn (Zea mays), and sorghum (Sorghum bicolor). The species was first detected in the United States in 1980 and has since expanded its range eastward along the Gulf Coast reaching Louisiana in 2008. A disjointed introduction was detected in Florida in 2012, though range expansion of this population within the state has been limited. Most recently, a separate introduction was detected along the …

Context-Dependent Viral Transgenerational Immune Priming In Honey Bees (Hymenoptera: Apidae), Sarah Lang, Michael Simone-Finstrom, Kristen Healy

Faculty Publications

Transgenerational immune priming is the process of increased resistance to infection in offspring due to parental pathogen exposure. Honey bees (Apis mellifera L. (Hymenoptera: Apidae)) are hosts to multiple pathogens, and this complex immune function could help protect against overwhelming infection. Honey bees have demonstrated transgenerational immune priming for the bacterial pathogen Paenibacillus larvae; however, evidence for viral transgenerational immune priming is lacking across insects in general. Here we test for the presence of transgenerational immune priming in honey bees with Deformed wing virus (DWV) by injecting pupae from DWV-exposed queens and measuring virus titer and immune gene expression. Our …

Alternative Nesting Strategies Of Polistine Wasps In A Subtropical Locale, Scott Nacko, Mark A. Hall, Gregg Henderson

Faculty Publications

Phylogenetic studies suggest that historically all paper wasps (Vespidae: Polistinae) in North America have tropical origins, but some species have adapted to survive temperate conditions. Subtropical climates, which are intermediate between temperate and tropical, allow a unique opportu-nity to study ancestral traits which can be retained or lost within populations, and ultimately elucidate the process of social wasp evolution. We investigated the phenology of paper wasps at study sites in subtropical Baton Rouge, USA, through nest searching and monitoring of nest parameters throughout the warm season (March–October). Across the year, two periods of nest initiation occurred: from March–May (early season …

Holistic Management Of Pollinators And Pests: Integrating Semiochemicals With On-Farm Pesticides, Olabimpe O. Okosun, Gadi V.P. Reddy

Faculty Publications

Insect pollinators and insect herbivores affect plant reproduction and fitness. Floral displays are used to attract and manipulate pollinators' behavior to support plant sexual reproduction while rewarding the visitors with access to nectar and pollen. The plant-pollinator interactions use various semiochemicals as important communication channels for successful species interaction networks. Floral display and scents can also attract insect herbivores (in which case they act as kairomones). Consequently, semiochemical-color-based traps used for monitoring pest insects in crop fields often accidentally capture pollinators, and these interactions simultaneously affect pest monitoring, pollinator assemblages, and crop production in agroecosystems. An integrated interdisciplinary approach that …

On The Need For New Measures Of Phylogenomic Support, Robert C. Thomson, Jeremy M. Brown

Faculty Publications

The scale of data sets used to infer phylogenies has grown dramatically in the last decades, providing researchers with an enormous amount of information with which to draw inferences about evolutionary history. However, standard approaches to assessing confidence in those inferences (e.g., nonparametric bootstrap proportions [BP] and Bayesian posterior probabilities [PPs]) are still deeply influenced by statistical procedures and frameworks that were developed when information was much more limited. These approaches largely quantify uncertainty caused by limited amounts of data, which is often vanishingly small with modern, genome-scale sequence data sets. As a consequence, today's phylogenomic studies routinely report near-complete …

Seeing Red: Indigenous Land, American Expansion, And The Political Economy Of Plunder In North America, Eliot Fackler

Civil War Book Review

Michael John Witgen "concludes that the geographical expansion of the United States, especially in the northern Great Lakes homelands of the Anishinaabeg, depended not so much on military violence or even the immediate physical removal of Indigenous peoples. Rather, conquest was facilitated by a ‘political economy of plunder’ in which a coercive and duplicitous treaty process combined with the debt claims made by Indian agents, traders, and merchants to systematically separate Native nations from their land and annuity payments”
