Pharmaceuticals From Natural Products: The Utility Of The Phylogeny, Shaimaa Magdy Saad Jan 2023

Pharmaceuticals From Natural Products: The Utility Of The Phylogeny, Shaimaa Magdy Saad

Selected Full-Text Master Theses 2021-

About 60% of approved drugs during the last 30 years are either directly or indirectly from natural products. Previous studies have shown that the phylogeny has predictive utility in drug discovery. In this study the pharmacological applications of various naturally-derived drugs were mapped on the phylogeny reconstructed from DNA sequences of the source organisms to decipher phylogenetic patterns that may facilitate drug discovery. A multi-step approach was employed starting with a literature search to compile a comprehensive list of pharmaceutical drugs derived from natural sources. A phylogeny was reconstructed from the source organisms and their pharmacological uses mapped on the …

Bat Activity And Insect Biomass On Mcconnell Airforce Base Compared To Surrounding Wichita Parks, Michaela Sielaff Jan 2023

Bat Activity And Insect Biomass On Mcconnell Airforce Base Compared To Surrounding Wichita Parks, Michaela Sielaff

Master's Theses or Doctor of Nursing Practice

Bats are bioindicators of the communities to which they belong, giving researchers insight into the overall health of those ecosystems. Bats are also very adaptable and are capable of tolerating urbanization. Some species, such as Lasiurus borealis and Lasionycteris noctivagans may even benefit from adjacent industrial and commercial land use, although this is not the case for all bat species. In 2021, we began acoustic and mist net surveys of bats at McConnell Air Force Base (MAFB, or “base”) in Wichita, KS. However, no bats were captured or seen during mist net surveys, although some were detected acoustically over a …

Relationship Between Bats And Prairie-Dog (Cynomys Ludovicianus) Colonies In Western Kansas, Mario N. Rodriguez Jan 2023

Relationship Between Bats And Prairie-Dog (Cynomys Ludovicianus) Colonies In Western Kansas, Mario N. Rodriguez

Master's Theses or Doctor of Nursing Practice

Although it is known that prairie dog colonies can increase biodiversity in the areas surrounding them, there is extraordinarily little known about the relationship between bats and black-tailed prairie dogs (Cynomys ludovicianus). In a recent study from the Front Range of Colorado, several bat species were found to be consistently flying around prairie dog colonies, presumably foraging due to increased insect diversity and abundance. Despite the importance of prairie dogs to the ecosystem, prairie dog colonies are usually eradicated due to the perception that they adversely impact cattle grazing. If insectivorous bats are attracted to prairie dog colonies …

Methylation Patterns Across Tissue Type And Time In Peromyscus Leucopus: A Targeted Museum Study, Loryn Smith Jan 2023

Methylation Patterns Across Tissue Type And Time In Peromyscus Leucopus: A Targeted Museum Study, Loryn Smith

Master's Theses or Doctor of Nursing Practice

Museum specimens are a vital data source for many types of studies. One relatively new use includes studying methylation patterns. Methylation patterns are a form of epigenetics or how gene expression changes without alteration of the genetic code. These patterns have been examined in many mammals. However, the focus has previously been on overall epigenetic patterns. Few studies have investigated whether methylation patterns differ across tissue types, time, or preservation method. In this study, I compared methylation patterns in muscle, liver, toe pads, and nasal bones from Peromyscus leucopus (white-footed mouse) museum specimens collected in 2022, 2018, 2014, and 2008 …

Conservation Status Of The Chihuahuan Green Toad, Anaxyrus Debilis, In Western Kansas Range, Mackenzie Reh

Master's Theses or Doctor of Nursing Practice

Amphibians remain an important model organism closely associated with environmental conditions and ecological processes. They are considered critical bioindicators of the relative health of ecosystems providing insights into levels of pollution, such as agricultural and industrial runoff, effects of UVB increases, ecosystem service functionality and much more (Rohman et al. 2021). Amphibians are an essential food source to organisms at higher trophic levels and to humans in developing countries (Schleich et al. 1996). Amphibians also provide pest control for agricultural and urban landscapes (Warkentin et al. 2009). Amphibians provide novel medicinal treatments for a wide variety of human ailments and …

Grassland Nesting Birds And Visual Obstruction Measurements In Western Kansas On Smoky Valley Ranch, Connor J. Champney Jan 2023

Grassland Nesting Birds And Visual Obstruction Measurements In Western Kansas On Smoky Valley Ranch, Connor J. Champney

Master's Theses or Doctor of Nursing Practice

North American grassland declines and increasing changes in land use patterns have revived the importance of studying grasslands and their inhabitants. Grassland breeding bird populations are declining rapidly, and conservation efforts are ramping up. Smoky Valley Ranch (SVR) owned by The Nature Conservancy (TNC) is in Logan County, Kansas. Surrounding private land is characteristically comprised of row crops, livestock agriculture, Conservation Reserve Program (CRP), and a few patches of native and restored prairie. The study of obligate grassland birds utilizing this area during the breeding season is essential to the proliferation of grassland bird nesting habitat in western, Kansas. The …

Habitat Associations And Fine-Scale Movements Of The Red-Spotted Toad (Anaxyrus Punctatus) In Kansas And The Efficacy Of Remote Telemetry For Monitoring Small-Scale Movements, Elisabeth Russell Jan 2023

Habitat Associations And Fine-Scale Movements Of The Red-Spotted Toad (Anaxyrus Punctatus) In Kansas And The Efficacy Of Remote Telemetry For Monitoring Small-Scale Movements, Elisabeth Russell

Master's Theses or Doctor of Nursing Practice

As climate change progresses, arid-adapted anurans might be particularly susceptible to population declines because of their reliance on ephemeral pools for successful reproduction. Because arid-adapted anurans are difficult to study due to short active seasons and cryptic lifestyles, little is known about their habitat preferences. One such arid-adapted species is the Red-Spotted Toad (Anaxyrus punctatus; RST), a Kansas Species in Need of Conservation. Since this designation in 1987, little research has been conducted to understand their conservation needs. During the summers of 2021 and 2022, RST surveys were conducted both near areas where the species has historically been …

Investigating The Mechanism Of Tdp-43 Toxicity In Yeast: A Model For Amyotrophic Lateral Sclerosis, Cassidy Nicole Alspaugh Jan 2023

Investigating The Mechanism Of Tdp-43 Toxicity In Yeast: A Model For Amyotrophic Lateral Sclerosis, Cassidy Nicole Alspaugh

Browse all Theses and Dissertations

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that causes the degeneration of motor neurons which leads to loss of motor function and eventual death. Over 20 genes have been implicated in ALS’s pathogenesis, one being TARDBP, which codes for TDP-43. TDP-43 mislocalizes from the nucleus, accumulates, and then aggregates in the cytoplasm and is linked to cellular toxicity. We have modeled this aggregation and toxicity of TDP-43 in budding yeast. From genetic screens of human genes and their ability to modulate TDP-43 toxicity, we found 50 human genes that were able to reduce TDP-43 toxicity. 12 of these …

Territory Inheritance And The Evolution Of Cooperative Breeding In The Acorn Woodpecker, Walter D. Koenig, Joseph Haydock, Hannah L. Dugdale, Eric L. Walters Jan 2023

Territory Inheritance And The Evolution Of Cooperative Breeding In The Acorn Woodpecker, Walter D. Koenig, Joseph Haydock, Hannah L. Dugdale, Eric L. Walters

Biological Sciences Faculty Publications

There are two main hypotheses for why offspring in cooperatively breeding taxa delay dispersal and remain on their natal territory rather than disperse. First, ecological constraints may force offspring to remain on their natal territory until a reproductive opportunity presents itself in an otherwise saturated habitat. Alternatively, delaying dispersal and helping kin may increase an offspring's inclusive fitness. One means by which offspring might enhance their direct fitness by delaying dispersal is by inheriting breeding status on their natal territory. Such territory inheritance regularly occurs in acorn woodpeckers, Melanerpes formicivorus, a species whose social groups consist of a cooperatively …

Homogeneity Test On Error Rates From Ordinal Scores And Application To Forensic Science, Ngoc Ty Nguyen Jan 2023

Homogeneity Test On Error Rates From Ordinal Scores And Application To Forensic Science, Ngoc Ty Nguyen

Graduate Thesis and Dissertation 2023-2024

The Receiver Operating Characteristic (ROC) curve is used to measure the classification accuracy of tests that yield ordinal or continuous scores. Ordinal scores are common in medical imaging studies and, more recently, in black-box studies on forensic identification accuracy (Phillips et al., 2018). To assess the accuracy of radiologists in medical imaging studies or the accuracy of forensic examiners in biometric studies, one needs to estimate the ROC curves from the ordinal scores and account for the covariates related to the radiologists or forensic examiners. In this thesis, we propose a homogeneity test to compare the performance of raters. We …

What Kills The Virtually Immortal Palms Of The Florida Scrub?, Warren G. Abrahamson Ii Jan 2023

What Kills The Virtually Immortal Palms Of The Florida Scrub?, Warren G. Abrahamson Ii

Faculty Journal Articles

Premise: Life span varies greatly across plants, with some species being capable of extreme longevity. Yet even long‐lived individuals are susceptible to climatic events, fire, and other challenges. We examined rare mortality events and their causes in two long‐lived palmettos over four decades. Methods: We monitored the survival of the clonal Serenoa repens and non‐clonal, Florida‐endemic Sabal etonia from 1981 to 2022 in four habitats along an elevational gradient within the globally imperiled Florida scrub ecosystem. We considered several challenges to palmetto survival, including extreme fires, shading due to lack of fire, droughts, periods of high precipitation, and possible pathogens. …

Salt marshes occur globally across climatic and coastal settings, providing key linkages between terrestrial and marine ecosystems. However, salt marsh science lacks a unifying conceptual framework; consequently, historically well-studied locations have been used as normative benchmarks. To allow for more effective comparisons across the diversity of salt marshes, we developed an integrative salt marsh conceptual framework. We review ecosystem-relevant drivers from global to local spatial scales, integrate these multi-scale settings into a framework, and provide guidance on applying the framework using specific variables on 11 global examples. Overall, this framework allows for appropriate comparison of study sites by accounting for …

Lifetime Inclusive Fitness Effects Of Cooperative Polygamy In The Acorn Woodpecker, Walter D. Koenig, Sahas Barve, Joseph Haydock, Eric L. Walters Jan 2023

Lifetime Inclusive Fitness Effects Of Cooperative Polygamy In The Acorn Woodpecker, Walter D. Koenig, Sahas Barve, Joseph Haydock, Eric L. Walters

Biological Sciences Faculty Publications

Although over 50 y have passed since W. D. Hamilton articulated kin selection and inclusive fitness as evolutionary explanations for altruistic behavior, quantifying inclusive fitness continues to be challenging. Here, using 30 y of data and two alternative methods, we outline an approach to measure lifetime inclusive fitness effects of cooperative polygamy (mate-sharing or cobreeding) in the cooperatively breeding acorn woodpecker Melanerpes formicivorus. For both sexes, the number of offspring (observed direct fitness) declined while the number of young parented by related cobreeders (observed indirect fitness effect) increased with cobreeding coalition size. Combining these two factors, the observed inclusive …

Of Transcription Factor And Transformation: Elucidating Gene Function In The Common Ice Plant, Mesembryanthemum Crystallinum, Chinenye Lilian Izuegbunam

Dissertations and Theses

Abiotic stresses negatively affect plant growth and development across the globe, which also affect the production of food, feed, biofuel, and fiber to meet the demands of a growing population. Thus, developing novel strategies to increase abiotic stress tolerance in crops is necessary. One of these strategies is exploring transcription factors (TFs) in Crassulacean Acid Metabolism (CAM) plants to improve plant abiotic stress tolerances. Therefore, the first objective of this dissertation determine the abiotic stress tolerance function of a CAM TF, McHB7opt in Arabidopsis. This study found that McHB7opt increased stress-responsive pathways related to seed germination and early seedling development. …

An Analysis On How Housing Status Influences The Gut-Brain-Axis For Populations In And Around The Skid Row Area Of Los Angeles, California, Mauricio Guzman

Pitzer Senior Theses

Over recent years, the “microbiota-gut-brain axis” (MGBA) has garnered significant attention in the scientific community. Specifically, perturbations of the MGBA via stress and dietary intake have been linked to a wide-range of diseases including gastrointestinal diseases, metabolic diseases, mood disorders, and cognitive diseases. However, most studies have been solely conducted on mice models and have yet to consider the more complex, intricate systems that impact the human body. In addition, researchers have yet to consider the populations who may be most susceptible to chronic stress and negative dietary outcomes. Drawing from the fields of medical sociology, non-invasive human biology, and …

Exploring The Diversity Of Microeukaryotic Communities In New England Tide Pools, Adri K. Grow, Robin S. Sleith, Taylor R. Sehein, Michaela Labare, Laura A. Katz

Biological Sciences: Faculty Publications

Though historically understudied, due in large part to most species being uncultivable, microbial eukaryotes (i.e. protists) are abundant and widespread across diverse habitats. Recent advances in molecular techniques, including metabarcoding, allow for the characterization of poorly known protist lineages. This study surveys the diversity of SAR (Stramenopila, Alveolata, and Rhizaria), a major eukaryotic clade that is estimated to represent about half of all eukaryotic diversity. SAR lineages use varied metabolic strategies like mixotrophy in dinoflagellates (Alveolata), parasitism in apicomplexans (Alveolata) and labyrinthulids (Stramenopila), and life cycle stages that include encystment and attachment (e.g. in ciliates, Alveolata) to survive in highly …

Eye Lens Β-Crystallins Are Predicted By Native Ion Mobility-Mass Spectrometry And Computations To Form Compact Higher-Ordered Heterooligomers, Amber D. Rolland, Takumi Takata, Micah T. Donor, Kirsten J. Lampi, James S. Prell

Faculty Publications - Department of Biological & Molecular Science

Eye lens crystallin proteins maintain the refractive properties of the lens but are not replaced after denucleation. Rolland et al. use native ion mobility-mass spectrometry, kinetics experiments, and computations to reveal that b-crystallins form heterodimers. These likely assemble into compact heterooligomers that enable the very high protein concentrations found in lens tissue.

Exploring The Molecular Basis Of Touch: A Comparative Analysis Of Gene Expression In Sensory Corpuscle-Rich And Corpuscle-Poor Skin Regions In The Duck, Thomas Hart Jan 2023

Exploring The Molecular Basis Of Touch: A Comparative Analysis Of Gene Expression In Sensory Corpuscle-Rich And Corpuscle-Poor Skin Regions In The Duck, Thomas Hart

Theses and Dissertations--Biology

Cutaneous touch is facilitated by discrete cellular complexes composed of non-neuronal cells associated with mechanoreceptor neuron endings. The non-neuronal cells of these cutaneous end organ complexes (CEOCs) are believed to contribute to touch, but their role in touch sensation remains unclear. To better understand the function of CEOC cells, we sought to characterize the transcriptional profile of CEOC-rich tissue and identify genes expressed in CEOC cells. Bill skin of the tactile foraging Pekin duck (Anas platyrhynchos) is dense with CEOCs, specifically the avian analogs of mammalian Pacinian and Meissner corpuscles, while corpuscles in duck foot skin are scarce. Using RNA …

Variation In Behavioral Strategies For Coping With Environmental Uncertainty, Allison Mclaughlin Jan 2023

Variation In Behavioral Strategies For Coping With Environmental Uncertainty, Allison Mclaughlin

Theses and Dissertations--Biology

My dissertation investigates how animals behaviorally respond to environmental change, especially when there is limited information about that change. Uncertainty about the environment comes in various forms, including food resources which vary unpredictably and novel cues which present an unknown level of potential risk or benefit. Various behavioral strategies help animals cope with such uncertainty. Tactics to manage unpredictable variation in food include gathering information to reduce uncertainty (sampling) and strategically adjusting preference or aversion to variation in resources (variance-sensitivity). To manage the uncertainty of a novel cue, animals may generalize their previous experience with similar cues, or they may …

Examining The Immune Regulation Of Nlrp12 Through Novel Protein Interactions, Catherine Rippe Jan 2023

Examining The Immune Regulation Of Nlrp12 Through Novel Protein Interactions, Catherine Rippe

Graduate Theses/Dissertations

NOD-like receptors (NLRs) are intracellular proteins that play an important role in the regulation of the innate immune response to pathogens. Since being identified, various functions for NOD-like receptor pyrin domain containing 12 (NLRP12) have been suggested. It has been shown to negatively regulate the inflammatory response through canonical and noncanonical NF-kB signaling pathways, control tumorigenesis and gut homeostasis and exacerbate inflammation through the formation of a multi-protein complex called an inflammasome. Due to the varying roles established for NLRP12, the mechanisms by which it functions remain poorly understood. In this study, I sought to confirm a novel protein-protein interaction …

The Role Of Insulin-Like Growth Factor I In The Development Of The Cerebellum In Euthyroid And Hypothyroid Mice, Prathibha Mangedarage

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone deficiency during development is known to cause anatomical defects in the cerebellum that lead to neurological deficits. It has been observed that insufficient thyroid hormone levels also decrease the levels of brain derived Insulin-like growth factor 1 (Igf-1). Given that the deficits caused by low Igf-1 levels are similar to those caused by low thyroid hormone, we designed this study to investigate if the deficits caused in the development of the cerebellum by low thyroid hormone levels may be due to the lack of sufficient Igf-1. We also sought to determine if ectopic over expression of Igf-1 in …
