Investigations Of The Structure And Protein-Protein Interactions Of Chlamydia Trachomatis Scc4, Thilini Oshadhi Senarath Ukwaththage Mar 2021

Investigations Of The Structure And Protein-Protein Interactions Of Chlamydia Trachomatis Scc4, Thilini Oshadhi Senarath Ukwaththage

LSU Doctoral Dissertations

Chlamydia trachomatis (CT) is the most common, sexually transmitted bacterial disease (STD) in the world. In the developmental cycle of CT, specific chlamydia chaperone 4 (Scc4) is a unique protein with essential and multiple roles. Hence, Scc4 is significant as a virulence target for therapeutic approaches to treat chlamydial infections. A novel approach was discovered to purify tag free Scc4 by utilizing a 6X-histidine-tag on Scc1 in the co-expressed Scc4:Scc1 complex by capturing the complex on nickel-charged immobilized metal affinity chromatography resin, followed by dissociation of Scc4 with sarkosyl. Using triple resonance NMR experiments, backbone and sidechain resonances …

Making Room For Fat Student Affairs Professionals In Higher Education, Wesley Heath Mar 2021

Making Room For Fat Student Affairs Professionals In Higher Education, Wesley Heath

LSU Doctoral Dissertations

Sizeism is often called the last acceptable form of prejudice in our social world. Weight discrimination has been widely documented in job searches, doctors’ offices, promotions, wage gaps, education, and even courtrooms. Despite decades of critical weight scholarship, little research has been done on fat higher education employees. Using the critical theory and the fat studies theoretical framework, this phenomenological study explores bias, prejudice, and discrimination experienced by fat student affairs professionals on college campuses. Four overarching research questions were identified and focused on the following topics: the limitations of physical space on college campuses, perceptions of available resources, stereotypes …

Intimate Rhetorics Of Networked Motherhood, Katie Nelson Mar 2021

Intimate Rhetorics Of Networked Motherhood, Katie Nelson

LSU Doctoral Dissertations

Fundamentally pregnant bodies are understood, similarly to women’s bodies, as necessitating discipline. However, new networked forums have emerged where pregnancy is understood as affirming and having the capacity to challenge a silenced subject position. Using three case studies, the #IHadAMiscarriage Instagram page, the #TakeBackPostpartum Instagram page, and mediatized discourses surrounding Kylie Jenner’s pregnancy, this dissertation writes intimate publicity into these mediatized transgressions of pregnancy and postpartum. I argue discourses about pregnancy and postpartum in these networked spaces constitute intimate publics through the cultivation of shared affected investments and divestments in embodied experiences. These investments in the embodied experiences are crafted …

Applications Of Quantum Optics: From The Quantum Internet To Analogue Gravity, Anthony Brady Mar 2021

Applications Of Quantum Optics: From The Quantum Internet To Analogue Gravity, Anthony Brady

LSU Doctoral Dissertations

The aim of this thesis is to highlight applications of quantum optics in two very distinct fields: space-based quantum communication and the Hawking effect in analogue gravity. Regarding the former: We simulate and analyze a constellation of satellites, equipped with entangled photon-pair sources, which provide on-demand entanglement distribution ser- vices to terrestrial receiver stations. Satellite services are especially relevant for long-distance quantum-communication scenarios, as the loss in satellite-based schemes scales more favor- ably with distance than in optical fibers or in atmospheric links, though establishing quantum resources in the space-domain is expensive. We thus develop an optimization technique which balances …

The Age-Dependent Characterization Of The Er-Alpha Positive Breast Cancer Tumor Microenvironment, Katie Marie Hamel Mar 2021

The Age-Dependent Characterization Of The Er-Alpha Positive Breast Cancer Tumor Microenvironment, Katie Marie Hamel

LSU Doctoral Dissertations

In disease states such as cancer, endocrine and paracrine signals from adipose tissue contribute to cancer progression and drug resistance. Young individuals diagnosed with estrogen receptor-alpha positive (ER-a+) breast cancer have an observed increase in resistance to endocrine therapies. This suggests that an alternative estrogen signaling pathway is active within these tumors. Despite this, the effects of stromal age on the endocrine response in breast cancer is not well known. Here, we review and highlight the involvement of the stromal age in both tumorigenesis and physiological wound healing. To identify specific differences between young and aged ER-a+ breast tumors, RNA …

"Will God Forgive Us?": Christianity And The Climate Crisis In Auteur Cinema, Margaret Alice Parson Mar 2021

"Will God Forgive Us?": Christianity And The Climate Crisis In Auteur Cinema, Margaret Alice Parson

LSU Doctoral Dissertations

Climate change is an unavoidable and real catastrophic threat to the future of Planet Earth. This dissertation is interested in how contemporary auteur cinema draws on Christian forms to give expression to the ineffability of environmental collapse. In this rhetorical generic criticism, I discuss three recent auteur films: First Reformed (2017, directed by Paul Schrader), Interstellar (2014, directed by Christopher Nolan), and mother! (2017, directed by Darren Aronofsky). In order to best rhetorically analyze these films, I perform a generic criticism which utilizes aspects of psychoanalysis and affect theory as per the work of Gunn. Each film is …

The Dna Cloud: Is It Alive?, Theodoros Bargiotas

LSU Doctoral Dissertations

In this analysis, I will firstly be presenting the current knowledge concerning the materiality of the internet based Cloud, which I will henceforth be referring to as simply the Cloud. For organisation purposes I have created two umbrella categories under which I place the ongoing research in the field. Scholars have been addressing the issue of Cloud materiality through broadly two prisms: sociological materiality and geopolitical materiality. The literature of course deals with the intricacies of the Cloud based on its present ferromagnetic storage functionality. However, developments in synthetic biology have caused private tech companies and University spin-offs to flirt …

Experiences Of Hospitalization For Suicide Ideation And Suicide Attempt In Gender Diverse Adults, Alix B. Aboussouan Mar 2021

Experiences Of Hospitalization For Suicide Ideation And Suicide Attempt In Gender Diverse Adults, Alix B. Aboussouan

LSU Master's Theses

Individuals who identify as Transgender/Gender Diverse (TGD) have elevated rates of suicidal thoughts and behaviors (STBs). No studies have determined the prevalence of hospitalization for STBs in TGD adults or whether this care is viewed as helpful. Understanding hospitalization experiences may determine potential new treatment targets and training initiatives integral to developing affirming care experiences for TGD individuals. This study sought to explore the lifetime prevalence of hospitalization for suicide ideation (SI) and suicide attempt (SA) for TGD individuals, determine how helpful TGD individuals find hospitalization, and investigate demographics, gender minority stressors, or provider/hospitalization characteristics that correlate with hospitalization helpfulness …

Exploring Attentional Biases, Dispositional Mindfulness, And The Suicide Stroop, Emma H. Moscardini Mar 2021

Exploring Attentional Biases, Dispositional Mindfulness, And The Suicide Stroop, Emma H. Moscardini

LSU Master's Theses

Extant research has found that attentional biases to suicide-related stimuli are relevant to suicidal thoughts and behaviors (STBs). As such, attentional biases are a core feature of both the Fluid Vulnerability Theory of Suicide and the cognitive model of suicide. Individuals with an STB history have demonstrated attentional biases to suicide-related stimuli on a suicide Stroop task, and this attentional bias has been found to aid in prediction of suicide attempts at six-month follow-up. Better understanding this attentional bias may be useful for informing mindfulness-based interventions which target attentional biases, as dispositional mindfulness has been found to be related to …

The Epigenetics Of Gametes And Early Embryos And Potential Long-Range Consequences In Livestock Species—Filling In The Picture With Epigenomic Analyses, Linkai Zhu, Sadie L. Marjani, Zongliang Jiang Mar 2021

The Epigenetics Of Gametes And Early Embryos And Potential Long-Range Consequences In Livestock Species—Filling In The Picture With Epigenomic Analyses, Linkai Zhu, Sadie L. Marjani, Zongliang Jiang

Faculty Publications

The epigenome is dynamic and forged by epigenetic mechanisms, such as DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA species. Increasing lines of evidence support the concept that certain acquired traits are derived from environmental exposure during early embryonic and fetal development, i.e., fetal programming, and can even be “memorized” in the germline as epigenetic information and transmitted to future generations. Advances in technology are now driving the global profiling and precise editing of germline and embryonic epigenomes, thereby improving our understanding of epigenetic regulation and inheritance. These achievements open new avenues for the development of technologies or potential …

A Single-Well Gas-Assisted Gravity Drainage Enhanced Oil Recovery Process For U.S. Deepwater Gulf Of Mexico Operations, Bikash D. Saikia, Dandina N. Rao Mar 2021

A Single-Well Gas-Assisted Gravity Drainage Enhanced Oil Recovery Process For U.S. Deepwater Gulf Of Mexico Operations, Bikash D. Saikia, Dandina N. Rao

Faculty Publications

The U.S. Deepwater Gulf of Mexico (DGOM) area that has some of the most prolific oil reservoirs is still awaiting the development of a viable enhanced oil recovery (EOR) process. Without it, DGOM will remain severely untapped. Exorbitant well costs, in excess of $200 million, preclude having extensive injection patterns, commonly used in EOR design frameworks. Aside from injection patterns, even operationally waterflooding has met with significant challenges because of injectivity issues in these over pressurized turbidities. The gas-assisted gravity drainage (GAGD) EOR process, that holds promise for deepwater environments because of lesser injectivity issues, among others, has been adapted …

© 2021 The Authors Leaf-level gas exchange data support the mechanistic understanding of plant fluxes of carbon and water. These fluxes inform our understanding of ecosystem function, are an important constraint on parameterization of terrestrial biosphere models, are necessary to understand the response of plants to global environmental change, and are integral to efforts to improve crop production. Collection of these data using gas analyzers can be both technically challenging and time consuming, and individual studies generally focus on a small range of species, restricted time periods, or limited geographic regions. The high value of these data is exemplified by …

Spatial modes of light constitute valuable resources for a variety of quantum technologies ranging from quantum communication and quantum imaging to remote sensing. Nevertheless, their vulnerabilities to phase distortions, induced by random media, impose significant limitations on the realistic implementation of numerous quantum-photonic technologies. Unfortunately, this problem is exacerbated at the single-photon level. Over the last two decades, this challenging problem has been tackled through conventional schemes that utilize optical nonlinearities, quantum correlations, and adaptive optics. In this article, the self-learning and self-evolving features of artificial neural networks are exploited to correct the complex spatial profile of distorted Laguerre–Gaussian modes …

Characterization, Immobilization, And Polymer Related Applications Of Watermelon Seed Powder, A Practical Source Of Urease Enzyme, Anthony Quan Quoc Mai

LSU Doctoral Dissertations

Urease enzyme was crystallized almost a century ago, and to this day its intrinsic stability is not ideal for everyday applications. This work introduces a new process by which a naturally encapsulated material, watermelon seed powder (WMSP), is characterized for its stability and activity. WMSP enzymatic activity has been measured for over a year at various storage conditions—exposed to ambient atmosphere for a year, WMSP retained above 90% activity. In aqueous conditions, the enzyme maintained above 60% activity after two months; with the addition of a preservative that number stays at about 90%. There is a pH shift of the …

Clinical Research Faculty Publications

Objective: Stay-at-home orders in response to the coronavirus disease 2019 (COVID-19) pandemic have forced abrupt changes to daily routines. This study assessed lifestyle changes across different BMI classifications in response to the global pandemic. Methods: The online survey targeting adults was distributed in April 2020 and collected information on dietary behaviors, physical activity, and mental health. All questions were presented as “before” and “since” the COVID-19 pandemic. Results: In total, 7,753 participants were included; 32.2% of the sample were individuals with normal weight, 32.1% had overweight, and 34.0% had obesity. During the pandemic, overall scores for healthy eating increased (P < 0.001), owing to less eating out and increased cooking (P < 0.001). Sedentary leisure behaviors increased, while time spent in physical activity (absolute time and intensity adjusted) declined (P < 0.001). Anxiety scores increased 8.78 ± 0.21 during the pandemic, and the magnitude of increase was significantly greater in people with obesity (P ≤ 0.01). Weight gain was reported in 27.5% of the total sample compared with 33.4% in participants with obesity. Conclusions: The COVID-19 pandemic has produced significant health effects, well beyond the virus itself. Government mandates together with fear of contracting the virus have significantly impacted lifestyle behaviors alongside declines in mental health. These deleterious impacts have disproportionally affected individuals with obesity.
