Designing Development Programs For Non-Traditional Antibacterial Agents, John H. Rex, Holly Fernandez Lynch, I. Glen Cohen, Jonathan J. Darrow, Kevin Outterson

Faculty Scholarship

In the face of rising rates of antibacterial resistance, many responses are being pursued in parallel, including ‘non-traditional’ antibacterial agents (agents that are not small-molecule drugs and/or do not act by directly targeting bacterial components necessary for bacterial growth). In this Perspective, we argue that the distinction between traditional and nontraditional agents has only limited relevance for regulatory purposes. Rather, most agents in both categories can and should be developed using standard measures of clinical efficacy demonstrated with non-inferiority or superiority trial designs according to existing regulatory frameworks. There may, however, be products with non-traditional goals focused on population-level benefits …

Theses

Automated interpretation of human emotion has become increasingly important as human-computer interactions become ubiquitous. Affective computing is a field of computer science concerned with recognizing, analyzing and interpreting human emotions in a range of media, including audio, video, and text. Social media, in particular, are rich in expressions of people's moods, opinions, and sentiments. This thesis focuses on predicting the emotional intensity expressed on the social network Twitter. In this study, we use lexical features, sentiment and emotion lexicons to extract features from tweets, messages of 280 characters or less shared on Twitter. We also use a form of transfer …

Registration Of Diffusion Tensor Images In Log-Euclidean And Euclidean Space, Kevin Tuttle

Theses

Diffusion Tensor Imaging is a type of Magnetic Resonance Imaging that allows for the examination of brain connectivity and axonal integrity. Diffusion Tensor Images are created by capturing Diffusion-Weighted MRI images with specific RF pulses, inputing the images and the RF pulse gradient vectors into a set of equations, and solving the equations with linear algebra. To compare one DTI image with another, the images can be aligned using Image Registration. Image Registration works by defining a metric that describes the similarity between two images and iteratively transforming one of the images until the similarity measure is minimized. Existing methods …

Small-Scale Production And Meaningful Work: Toward A Community Of Gift And Craft, Stephen Michael Wolfe

LSU Master's Theses

Productive labor is often treated as a means for various ends—for money, leisure, play, etc. This essay argues that work, depending its scale and its relation to community, can be worth doing for its own sake—as an end in itself. Meaningful work is meaning-investing activity. In small-scale production, which involves an intimate relation with the material and an application of practical skill, the producers can invest products with higher-order meaning, imbuing upon them their personhood by which they manifest themselves in public for recognition as persons qua workers and for the judgment of others concerning the goodness of the product. …

Current And Future Deposition Of Nitrogen And Sulfur In Louisiana, Jessica Nguyen

LSU Master's Theses

Nitrogen (N) and sulfur (S) are essential nutrients, however excess quantities can stress ecosystems. Atmospheric nitrogen and sulfur deposition lead to changes in water and soil chemistry, consequently resulting in ensuing detriment to multiple ecosystems such as acidification of water bodies. This affects a multitude of plants and animals such as trees, insects, and fish. Louisiana has copious natural water resources. Therefore, it is essential to safeguard its valuable resources from excess atmospheric N and S deposition. However, knowledge of N and S deposition and its unfavorable effects in the Southeast U.S., particularly Louisiana, is limited.

LSU Master's Theses

Cylas formicarius elegantulus (Summers) and Euscepes postfaciatus (Fairmaire) are the most destructive sweetpotato weevils in the Caribean Basin. However, damage occurring in sweetpotato production in Haiti is attributed to C. formicarius (S), since it is known to be the most prevalent species while, conflicting information is available pertaining to the occurrence of the E. postfaciatus (F). This study was conducted in the summer of 2018 to determine the presence or absence of E. postfaciatus (F) in Haiti. 98 weevil samples from field (70% ) and infested sweetpotato roots from field and regional markets were collected (30%) in the most relevant …

Development Of The Electrohydromodulation Process For Simultaneous Recovery Of Nitrogen And Phosphorus From Municipal Wastewater, Mahamalage Kusumitha Perera

Open Access Dissertations

The demand for phosphorous (P) fertilizer is projected to increase by 100% by the end of the century, and the use of nitrogen (N) fertilizer is increasing exponentially as well. Current single-use nutrient management practices have led to environmental impacts of mining, extensive greenhouse gas emissions and surface water eutrophication. Recovery and reuse of nutrients would reduce solubilizing plant available N and P in the environment. Thus, the embedded energy in fertilizer production can be retained while minimizing the conversion of stable forms of N and P. Wastewater was identified as a potential source to recover nutrients, as wastewater contains …

Open Access Dissertations

Relying on the rapid development of computer technology, machine learning is increasingly being applied to studies of animal behaviors. Video tracking enables observation of behaviors in an automatic, reliable and consistent way for an extended period. In Drosophila melanogaster, the fruit fly, various machine learning techniques have proven to be powerful tools in studies of locomotion tracking and overall behavior classification. In our study, we applied machine learning to investigate two important behaviors of flies: grooming and sleep. Despite being universally existing in almost all animals, the regulation of grooming is poorly understood. In the first application, based on a …

The Role Of Fibrosis After Experimental Autoimmune Encephalomyelitis, Stephanie L. Yahn

Open Access Dissertations

Remyelination failure is a crucial component of disease progression in the autoimmune demyelinating disease Multiple Sclerosis (MS). The regenerative capacity of oligodendrocyte progenitor cells (OPCs) to replace myelinating oligodendrocytes is likely influenced by many aspects of the lesion environment including inflammatory signaling and extracellular matrix (ECM) deposition. These features of MS lesions are typically attributed to infiltrating leukocytes and reactive astrocytes. Here we demonstrate that fibroblasts also contribute to an inhibitory environment in the animal model of MS, experimental autoimmune encephalomyelitis (EAE). Using Col1α1GFP transgenic mice, we show that perivascular fibroblasts are activated in the spinal cord at EAE onset …

Spatial Chromatin Architecture Alteration By Structural Variations In Human Genomes At The Population Scale., Michal Sadowski, Agnieszka Kraft, Przemyslaw Szalaj, Michal Wlasnowolski, Zhonghui Tang, Yijun Ruan, Dariusz Plewczynski

Faculty Research 2019

BACKGROUND: The number of reported examples of chromatin architecture alterations involved in the regulation of gene transcription and in disease is increasing. However, no genome-wide testing has been performed to assess the abundance of these events and their importance relative to other factors affecting genome regulation. This is particularly interesting given that a vast majority of genetic variations identified in association studies are located outside coding sequences. This study attempts to address this lack by analyzing the impact on chromatin spatial organization of genetic variants identified in individuals from 26 human populations and in genome-wide association studies.

RESULTS: We assess …

Biosynthesis Of Ambrein In Ambergris: Evidence From Isotopic Data And Identification Of Possible Intermediates, Steven J. Rowland, Paul A. Sutton, George A. Wolff

More Faculty of Science and Engineering Research

Ambrein is found in ambergris, a coprolith occurring in the rectum of the sperm whale. In vitro, ambrein is produced by enzymatic cyclisation of squalene, via a monocyclic intermediate. However, little is known of the in vivo process. In order to find evidence for the reaction in vivo, a comparison was made of the δ13C relative isotopic ratios of ambrein in ambergris with those of co-occurring sterols. A statistically significant difference was noted. This suggests that ambrein originates via a different biosynthetic mechanism from that of the sterols. Examination of the minor constituents of a hydrogenolysed extract of ambergris revealed …

An Analysis Of The Effect Of Tooth Wear On Bovid Identification, Juliet K. Brophy, Gregory J. Matthews, George K. Thiruvathukal

Mathematics and Statistics: Faculty Publications and Other Works

Previous research provides a method for reducing the subjectivity in taxonomic identification of species in the family Bovidae by quantifying the occlusal surface of molar teeth using elliptical Fourier analysis. In this current study, we specifically test what effect medium to late tooth wear has on the identification of bovids when using the form (size and shape) of the occlusal surface to classify specimens. To achieve this, the classification results of teeth with ≥85% of their occlusal surface (training data set) were compared with the results of teeth with <85% of their occlusal surface (test data set) due to wear. In the training data set, all tribes classified correctly >87% of the time with both Alcelaphini and Reduncini classifying correctly …

From Interior To Interiority: Locating Key Historical Moments In The Relationship Between Spaces And Individuals, Bruno Cruz Petit

Interiority

We spend increasingly more time in architectural interiors, spaces that can give us quality of life and interesting scenarios for the growth of identity and interiority. However, both spatial interior and psychological interiority faces difficulties inherent to contemporary life. This text proposes a critical review of the literature on the socio-spatial archeology of the subject in order to see possible paths of realisation of interiority in the present. The document presents several stages in the sociocultural evolution of an interior space that needs to be described with different adjectives (spiritual, hedonistic, promiscuous) and groups the most relevant contributions of the …

Reduced Alphabet Of Prebiotic Amino Acids Optimally Encodes The Conformational Space Of Diverse Extant Protein Folds, Armando D. Solis

Publications and Research

Background

There is wide agreement that only a subset of the twenty standard amino acids existed prebiotically in sufficient concentrations to form functional polypeptides. We ask how this subset, postulated as {A,D,E,G,I,L,P,S,T,V}, could have formed structures stable enough to found metabolic pathways. Inspired by alphabet reduction experiments, we undertook a computational analysis to measure the structural coding behavior of sequences simplified by reduced alphabets. We sought to discern characteristics of the prebiotic set that would endow it with unique properties relevant to structure, stability, and folding.

Results

Drawing on a large dataset of single-domain proteins, we employed an information-theoretic measure …

As such, it represents an ideal environment for examining the people, interactions, and flow of scientific information. Using interactions involving the four most popular Twitter hashtags for paleontology, this embedded mixed methods study defined the members of this social world and investigated how they influenced and controlled the flow of information, as well as how their expression of scientific practice …

Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss

USF Tampa Graduate Theses and Dissertations

Many diseases display a multitude of relevant factors that contribute to the persistence of the disease and difficulty treating it. The multifactorial characteristics of some diseases lead to the requirement of combination of treatments in order to restore health. The latter may necessitate the mixing of treatments, medications, and therapeutics to first halt the disease, then assist the human body in returning itself to a state of normality. For example, chronic wounds exhibit this multifactor characteristic in which there exist many factors that lead to the body’s inability to properly heal in a timely manner. This presents a further threat …

Eutherian Biogeography During The Puercan North American Land Mammal Age (Paleocene, Earliest Danian): Problems And Potential Solutions, Jason Sterling Silviria

Earth and Planetary Sciences ETDs

The Puercan North American Land Mammal Age (NALMA) is the earliest major North American terrestrial biochron of the Cenozoic era, spanning roughly the first one million years of the Paleogene period (Paleocene epoch, Danian stage; ~66.04-65.12 Ma). It is typified by the explosive ecomorphological diversification of the mammalian clade Eutheria (particularly our subclade, Placentalia), following the annihilation of non-avian dinosaurs and “archaic” mammal groups during the Cretaceous/Paleogene (K-Pg) mass extinction event. The spatiotemporal mode and tempo of Puercan eutherian diversification has long been the subject of debate, with disagreements over biogeographic zonation. The traditional model – based largely on well-sampled, …

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The melting temperature of water reaches its minimum when pressurized from 0 °C at atmospheric pressure down to -22 °C at 220 MPa, showing that frozen products at atmospheric pressure (0.1 MPa) can be thawed rapidly by simply increasing the pressure to 210-250 MPa. High pressure thawing (HPT) of poultry meats (ground chicken, chicken breast, thigh, liver, gizzard, and heart) commonly used in the raw pet food industry was evaluated at 240 MPa, two processing fluid temperatures (refrigerated, 0-10 °C and room, 20-30 °C), and four holding times (1, 180, 360, and 540 s). Changes in color via * * …

Changes In Mammalian Abundance Through The Eocene–Oligocene Climate Transition In The White River Group Of Nebraska, Usa, Robert Gillham

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Marine records show major cooling during the Eocene-Oligocene Climate Transition (EOCT). Most proxy studies in the White River Group suggest drying across the EOCT, and some suggest cooling. The lower resolution continental record has hindered a direct correlation of the marine climate record to Nebraska. I explore various correlation schemes and what they imply for faunal changes. This study compiles and analyzes data from 4,875 specimens in the University of Nebraska State Museum (UNSM) collection to test the hypothesis that climate change across the Eocene-Oligocene (E-O) boundary caused significant abundance changes in mammals. A series of binning schemes was created. …
