The Behavioral Specialization Of African Ant-Following Birds On Dorylus Driver Ants, Patricia F. Rodrigues

LSU Doctoral Dissertations

Ant-following birds, that forage on arthropods flushed by swarm raiding army ants, are an iconic phenomenon in tropical forests around the globe. Despite capturing the attention of naturalists for over a century, research on ant-following birds has largely focused on Neotropical species. Decades of research on Neotropical ant-following birds has revealed fascinating aspects of their specialization, including complex cognitive and behavioral adaptations that allow birds to locate and track nomadic army ants. Despite this breadth of research on Neotropical species, virtually nothing is known of the behavioral ecology of African ant-following birds, and it remains unknown whether they exhibit adaptations …

Novel Mutation Leading To Splice Donor Loss In A Conserved Site Of Dmd Gene Causes Duchenne Muscular Dystrophy With Cryptorchidism, Jianhai Chen, Yangying Jia, Jie Zhong, Kun Zhang, Hongzheng Dai, Guanglin He, Fuping Li, Li Zeng, Chuanzhu Fan, Huayan Xu

Faculty, Staff and Students Publications

Background: As one of the most common congenital abnormalities in male births, cryptorchidism has been found to have a polygenic aetiology according to previous studies of common variants. However, little is known about genetic predisposition of rare variants for cryptorchidism, since rare variants have larger effective size on diseases than common variants.

Methods: In this study, a cohort of 115 Chinese probands with cryptorchidism was analysed using whole-genome sequencing, alongside 19 parental controls and 2136 unaffected men. Additionally, CRISPR-Cas9 editing of a conserved variant was performed in a mouse model, with MRI screening used to observe the phenotype.

Results: In …

2020-Current year OA Pubs

Many routes may lead to the transition from a healthy to a diseased phenotype. However, there are not so many routes to travel in the opposite direction; that is, therapy for different diseases. The following pressing question thus remains: what are the pathogenic routes and how can be they counteracted for therapeutic purposes? Human cells contain >500 protein kinases and nearly 200 protein phosphatases, acting on thousands of proteins, including cell growth factors. We herein discuss neurotrophins with pathogenic or metabotrophic abilities, particularly brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), pro-NGF, neurotrophin-3 (NT-3), and their receptor Trk (tyrosine receptor …

Potential Value Of Brazzein-Yeast As A Broiler Chicken Feed Additive, Lauren Ruth Neuleib

Theses and Dissertations

A variety of flavors, including sweeteners, have been used in animal feeds to improve feed palatability and increase feed intake by livestock (Chen et al., 2020). While many of these sweeteners are found in the form of carbohydrates, brazzein is a sweet-tasting protein. This study was conducted to identify the potential of brazzein to influence feed intake by livestock, using poultry as a model. The preliminary study's purpose was to develop methods appropriate for the subsequent feeding study. In the preliminary study, eight pens of five birds were fed one of four treatment diets: Control or the Control plus one …

Storywood: Collaborating With Opaque Unknowable Others Through Oil Painting, Tanya J. Behrisch

Journal of Contemplative and Holistic Education

This paper demonstrates the use of contemplation and arts-based research (ABR) to explore intersubjectivity between myself and other opaque beings. Through a walking meditation, I experience an affective encounter with a plywood board found lying on a beach. The board radiates agency and mysterious stories about its passage through the world. Drawing on philosopher Tim Lilburn’s concept of permeable attention and Bennett’s theory of vibrant matter, I discover the storied nature of the damaged board and resonances between its stories and my own. By practicing perceptual openness, I discern vitality shimmering beyond the visible surface of the board. During my …

Denigration Of The Body In Plato’S Philosophy, Jamie Alexander

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The denigration of the body is a common feature of Western religions, but its origins can be traced back to Plato. His teacher, Socrates, proposed a separation of body and soul, but careful reading of Plato's Dialogues suggest Plato took a particularly negative view of the body compared to his predecessor. Analyzing the effects of the Peloponnesian War on Plato's life and society, this article looks at reasons Plato may have had a developed an unfavorable view toward the body by comparing "war bodies" with "intellectual bodies," and discussing the impact democracy had on Plato's worldview.

The Role Of Value Stream In Measuring Environmental Costs And Reducing Costs, Saba Shaker Dhari, Muqdad Ahmed Nouri

Journal of Economics and Administrative Sciences

Most economic units suffer from high rates of environmental pollution and a shortage of available resources and energy. This iead to a significant increase in production costs. In addition the economic units lack of using modern cost methods through which environmental costs and production costs are identified, allocated and measured. One of these methods is the value flow method . which works to track production processes, analyze inputs and outputs, and classify them into sound products and unhealthy products (waste).This in turn enables management to identify value-added activities and non-value-added activities, and works to reduce environmental impacts, the amount of …

Membrane Vectorial Lipidomic Features Of Coral Host Cells’ Plasma Membrane And Lipid Profiles Of Their Endosymbionts Cladocopium, Tatyana V Sikorskaya, Ekaterina V Ermolenko, Taliya T Ginanova, Andrey V Boroda, Kseniya V Efimova, Mikhail Bogdanov

Faculty, Staff and Student Publications

The symbiotic relationships between coral animal host and autotrophic dinoflagellates are based on the mutual exchange and tight control of nutritional inputs supporting successful growth. The corals Sinularia heterospiculata and Acropora aspera were cultivated using a flow-through circulation system supplying seawater during cold and warm seasons of the year, then sorted into host cells and symbionts and subjected to phylogenetic, morphological, and advanced lipid analyses. Here we show, that the lipidomes of the dinoflagellates Cladocopium C1/C3 and acroporide-specific Cladocopium hosted by the corals, are determined by lipidomic features of different thermosensitivity and unique betaine- and phospholipid molecular species. Phosphatidylserines and …

S–Domination Number In Graphs, Sarah H. A. Alsaebari, Ahmed A. Omran

Baghdad Science Journal

Let G (V, E) be a graph, the set D⊆ V is dominating set if each vertex v∈ V is either in D or is adjacent to a vertex in D and if there is no dominating subset of D, D will minimal dominating of a graph G. The domination number γ(G) is the minimum cardinality of all members of a minimal dominating set of a graph G. If V-D includes dominating set D' of vertices of a graph G then D' is called an inverse dominating set to D such that γ^-1(G) is the minimum cardinality of …

Optimization Of A Sers-Based Vertical Flow Immunoassay Utilizing A Plasmonic Syringe Filter For Rapid Biomarker Detection And Quantification, Anthony Abeiku Amissah

Theses and Dissertations

Many current diagnostic tools for accurate disease detection and quantification are often tedious and involve multiple complex steps. Consequently, there is a critical need for alternative point-of-care devices that are affordable and deliver rapid and reliable results. Recently, surface-enhanced Raman spectroscopy (SERS) has emerged as a highly effective analytical method, enhancing Raman scattering of molecules adsorbed onto nanoparticles and allowing for low-level detection and quantitative chemical analysis. In this study, we employ SERS to develop a rapid diagnostic test using human immunoglobulin G (hIgG) as a model biomarker because it is abundant in human serum, cheap, readily available, and well-understood. …

Risk Of Invasive Waterfowl Interaction With Poultry Production: Understanding Potential For Avian Pathogen Transmission Via Species Distribution Models, Reilly T. Jackson, Percival Matzinger Marshall, Chris R. Burkhart, Julia Schneck, Grant Kelly, Caleb P. Roberts

Biological Sciences Faculty Publications and Presentations

Recent outbreaks of highly pathogenic avian influenza have devastated poultry production across the United States, with more than 77 million birds culled in 2022–2024 alone. Wild waterfowl, including various invasive species, host numerous pathogens, including highly pathogenic avian influenza virus (HPAIV), and have been implicated as catalysts of disease outbreaks among native fauna and domestic birds. In major poultry-producing states like Arkansas, USA, where the poultry sector is responsible for significant economic activity (>$4 billion USD in 2022), understanding the risk of invasive waterfowl interactions with domestic poultry is critical. Here, we assessed the risk of invasive waterfowl-poultry interaction …

The Evolving Use Of Gold Nanoparticles As A Possible Reversal Agent For The Symptoms Of Neurodegenerative Diseases: A Narrative Review, Alan D. Kaye, Kelly R. Sala, Drew Dethloff, Matthew Norton, Corey Moss, Michael J. Plessala, Alyssa G. Derouen, Yair Lopez Torres, Julian Kim, Sridhar Tirumala, Sahar Shekoohi, Giustino Varrassi

School of Medicine Faculty Publications

Neurodegenerative diseases are broadly hallmarked by impaired energy metabolism and toxic intracellular accumulations such as damaged organelles or reactive oxygen species (ROS). Gold nanoparticles readily cross the blood-brain barrier and increase nicotinamide adenine dinucleotide + hydrogen (NADH) oxidation to nicotinamide adenine dinucleotide (NAD+), which is vital for intracellular energy generation, cellular repair, and protection from ROS. Thus, the use of gold nanoparticles to treat and potentially reverse cellular injury seen in neurodegenerative disease has been an area of ongoing research. This systematic review explores current literature regarding the use of gold nanoparticle therapy in the treatment of neurodegenerative diseases such …

Emerson Among The Methodists, Claudia Stokes

English Faculty Research

This essay examines the influence of Methodism on Emerson. During Emerson’s lifetime, Methodism exerted extraordinary influence on American religious life, yet he offered little comment on this important religious movement. In spite of this omission, this essay argues that Methodism shaped Emerson’s ideas about oratory, prayer, and self-determination. This essay examines two Methodist figures whom Emerson repeatedly cited as important influences: famed Methodist minister Edward Thompson Taylor and a less-remembered farm worker named Tarbox, whom Emerson met in his twenties and repeatedly mentioned in his journals. Emerson took inspiration from both men, but seems to have been unaware of the …

Man Up: Masculinity And Emotional Abuse Victimization, Kola Brown

Electronic Theses and Dissertations Archive

Intimate Partner Violence (IPV) is often only thought of in the context of physical violence towards women perpetrated by men. Historically, this form of violence garnered much attention due to its objective and visible nature. Unfortunately, other forms of abuse and male victims are often not recognized and result in victim blaming. One such form of abuse is psychological aggression. Studies show that men experience IPV at nearly equal rates as women, but that men experience psychological aggression, also referred to as emotional abuse, at higher rates. Additionally, Black families have the highest rates of abuse. However, due to abuse …

Sensorimotor Grounding In Novel Word Acquisition, John Michael Hollander

Electronic Theses and Dissertations Archive

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor encoding of new words and concepts. Further, research on embodiment and bilingualism suggests that second language semantic representations involve sensorimotor encoding, but because participants in these studies are already proficiently bilingual, the manner and degree to which L1 information influences newly learned word representations remain unclear. The experiments in this dissertation …

Neuropsychological Evaluation Of Retired Nfl Athletes With History Of Multiple Concussions: Examining Race-Norming Practices And Associations With Cognitive Functioning, Lauren Ashley-Marie Schenck

Electronic Theses and Dissertations Archive

This dissertation investigates the neuropsychological outcomes of retired NFL athletes with a history of multiple concussions, focusing on race-norming practices and their associations with cognitive outcomes. The primary objective was to investigate whether race-norming in neuropsychological assessment impacts ratings of cognitive impairment in this population. A secondary goal was to determine if concussion history and other health-related conditions could predict cognitive impairment status. To explore these aims, a comprehensive approach was adopted, involving a detailed review of existing literature, data collection from retired NFL players with a history of multiple concussions (including comprehensive neuropsychological examination), and rigorous statistical analysis. Participants’ …

Examining Severing Dynamics Of Cytoskeletal Structures Using Computational Methods, Arthur Peterson Miller

Theses

Within eukaryotic cells, cytoskeletal structures are a category of organelles that serve functions ranging from supporting cell geometry to locomotion. These functions require a coordinated effort of regulatory proteins, which interact with the cytoskeleton distinctively. Severing proteins, which can fragment cytoskeletal structures at their binding sites, are one such example. In this work, using stochastic modeling, we model the interaction of severing proteins on bare cytoskeletal filaments and bundled filaments, which are larger collections of individual filaments. We focus on two types of cytoskeletal protein structures in this work: cylindrical microtubules and linear actin filaments. In the case of microtubules, …

Seguir Adelante: A Qualitative Exploration Of Latino Farmworkers' Work And Non-Work Resources, Faviola Robles Saenz

Dissertations and Theses

Precarious work sectors within the United States have relied on Black and Brown labor for many decades. More specifically, Latino immigrant workers have been an exploited community within many dangerous workforces but especially within the agricultural industry. They are a crucial population for the labor and economy of the U.S., yet Latino farmworkers report feeling expendable, being discriminated against, and being exposed to hazardous working conditions. Due to these experiences, scholars have explored the role non-work resources have in providing support for this community, their social networks being especially beneficial for them. However, research on the links between their work …

An Exploration Of The Drivers Of Intraspecific Variation In Arthropod Phenotypes, Jamie Phelps

LSU Doctoral Dissertations

Herein we explore the various forces that drive phenotypic variation in arthropods focusing on spatial and temporal differences as well as sexual dimorphism. We use both marine, Tigriopus californicus, and terrestrial, Melitaeini, organisms to investigate these forces.

Tigriopus californicus and Heat Hardening: The study explores how Tigriopus californicus, a copepod, adapts to thermal variation along the North American Pacific Coast. Researchers investigated intraspecific variation in heat hardening, measuring differences in upper lethal limits (ULLs) and potential fecundity costs across five populations. We found a cost of heat hardening: the size of the first brood produced after heat shock …

Mucosal Signatures Of Pathogenic T Cells In Hla-B*27+ Anterior Uveitis And Axial Spondyloarthritis, Michael A. Paley, Lynn M. Hassman, Grace L. Paley, Nicole Linskey, Ryan Agnew, Paulo Henrique Arantes De Faria, Annie Feng, Sophia Y. Li, Elisha D. O. Roberson, Philip A. Ruzycki, Ekaterina Esaulova, Jennifer Laurent, Lacey Feigl-Lenzen, Luke E. Springer, Chang Liu, Wayne M. Yokoyama, Et Al.

2020-Current year OA Pubs

HLA-B*27 was one of the first HLA alleles associated with an autoimmune disease, i.e., axial spondyloarthritis (axSpA) and acute anterior uveitis (B27AAU), which cause joint and eye inflammation, respectively. Gastrointestinal inflammation has been suggested as a trigger of axSpA. We recently identified a bacterial peptide (YeiH) that can be presented by HLA-B*27 to expanded public T cell receptors in the joint in axSpA and the eye in B27AAU. While YeiH is present in enteric microbiota and pathogens, additional evidence that pathogenic T cells in HLA-B*27-associated autoimmunity may have had a prior antigenic encounter within the gastrointestinal tract remains lacking. Here, …

Investigating Gene Functions And Single-Cell Expression Profiles Of De Novo Variants In Orofacial Clefts, Toshiyuki Itai, Fangfang Yan, Andi Liu, Yulin Dai, Chihiro Iwaya, Sarah W Curtis, Elizabeth J Leslie, Lukas M Simon, Peilin Jia, Xiangning Chen, Junichi Iwata, Zhongming Zhao

Faculty, Staff and Student Publications

Orofacial clefts (OFCs) are common congenital birth defects with various etiologies, including genetic variants. Online Mendelian Inheritance in Man (OMIM) annotated several hundred genes involving OFCs. Furthermore, several hundreds of de novo variants (DNVs) have been identified from individuals with OFCs. Some DNVs are related to known OFC genes or pathways, but there are still many DNVs whose relevance to OFC development is unknown. To explore novel gene functions and their cellular expression profiles, we focused on DNVs in genes that were not listed in OMIM. We collected 960 DNVs in 853 genes from published studies and curated these genes, …

2020-Current year OA Pubs

BACKGROUND: Structural and functional changes of the choroid plexus (ChP) have been reported in Alzheimer's disease (AD). Nonetheless, the role of the ChP in the pathogenesis of AD remains largely unknown. We aim to unravel the relation between ChP functioning and core AD pathogenesis using a unique proteomic approach in mice and humans.

METHODS: We used an APP knock-in mouse model, APP

RESULTS: ChP tissue proteome was dysregulated in APP

CONCLUSIONS: Together, our findings support the hypothesis of ChP dysfunction in AD. These ChP changes were related to amyloid pathology. Therefore, the ChP could become a novel promising therapeutic target …

Predictors Of Counselors Accurately Diagnosing Obsessive Compulsive Disorder (Ocd) And Recommending Ocd-Specific Empirically Supported Treatments (Ests), Natalie Grierson

Walden Dissertations and Doctoral Studies

Research has supported that obsessive-compulsive disorder (OCD) is frequently misdiagnosed and not treated with OCD-specific, empirically supported treatments (ESTs) by healthcare professionals, resulting in negative consequences. Empirical findings are mixed regarding what predicts this and if counselors contribute to the concerns; therefore, it is imperative to investigate this with counselors. Using a medical model framework, the purpose of this quantitative study was to (a) examine the rate of counselors in the United States accurately diagnosing OCD, (b) identify the predictors for counselors accurately diagnosing OCD, (c) examine the rate of counselors recommending OCD-specific ESTs, and (d) identify the predictors for …

Marginalization And Environmental Risk: Women’S Roles In Making Plastic Woven Bags In Indonesia, Salsabila Damayanti, Siti Mas’Udah, Asia Ashfaq, Sudarso, Herdiyanti, Citra Asmara Indra, Merlia Indah Prastiwi

Journal of International Women's Studies

The plastic woven bag has become a symbolic representation of Indonesian women’s identity since the trend increased in 2021. The plastic woven bag represents femininity and the image of women as a result of socio-cultural construction. The activity of weaving paradoxically puts women in both a central and a marginal role. The weaving industry is characterized by an increasing number of platforms for women to generate income and improve their economic welfare. Nevertheless, women are still faced with patriarchal domination, because the demands of their domestic role limit their ability to move freely in public space. Therefore, their status as …
