Williams Honors College, Honors Research Projects
Even though poor glycemic control puts diabetics at risk for a variety of disease complications, there are many barriers to achieving adequate blood glucose regulation. Diabetic cardiac autonomic neuropathy (CAN) is a progressive autonomic denervation of the cardiovascular system resulting from chronic hyperglycemia and characterized by orthostatic hypertension, sinus tachycardia, low heart rate variability, and fatal arrhythmias. Available CAN therapeutics are limited to symptom alleviation, and do not prevent or reverse cardiac nerve damage. Limited evidence from clinical trials suggests the antioxidant Alpha Lipoid Acid (ALA) prevents CAN progression (Lee et al., 2017; Serhiyenko et al., 2020; Tankova, Koev & …

Theses and Dissertations--Molecular and Cellular Biochemistry
Protein Tyrosine Phosphatase 4A3 (PTP4A3 or PRL-3) is an oncogenic dual-specificity phosphatase that drives tumor metastasis, promotes cancer cell survival, and is correlated with poor patient prognosis in a variety of solid tumors and leukemias. The mechanisms that drive PRL-3’s oncogenic functions are not well understood, in part due to a lack of research tools available to study this protein. The development of such tools has proven difficult, as the PRL family is ~80% homologous and the PRL catalytic binding pocket is shallow and hydrophobic. Currently available small molecules do not exhibit binding specificity for PRL-3 over PRL family members, …

Artificial Light at Night Disrupts Pain Behavior and Cerebrovascular Structure in Mice
Jacob R. Bumgarner
Circadian rhythms are intrinsic biological processes that fluctuate in function with a period of approximately 24 hours. These rhythms are precisely synchronized to the 24- hour day of the Earth by external rhythmic signaling cues. Solar light-dark cycles are the most potent environmental signaling cue for terrestrial organisms to align internal rhythms with the external day. Proper alignment and synchrony of internal circadian rhythms with external environmental rhythms are essential for health and optimal biological function.
The modern human environment on Earth is no longer …

It Turned Into A Bioblitz: Urban Data Collection For Building Scientific Literacy And Environmental Connection, Kelly O'Donnell, Lisa Brundage
Publications and Research
In 2013, Macaulay Honors College redesigned its required science curriculum to focus on scientific literacy skills rather than content. Central to this shift was inclusion of a data collection event, a BioBlitz, to provide students with the basis for their own semester-long research projects. Students are teamed with naturalists in an urban green space to find as many species as they can in 24 h and to contribute to a global biodiversity database via the app iNaturalist. We have learned two important lessons: (1) developing an interdisciplinary curriculum with a high degree of experiential learning is more successful when both …
Food Waste Storage Gaseous Emissions Detection And Quantification Using Infrared Spectroscopy, 2023 Humboldt State University
Food Waste Storage Gaseous Emissions Detection And Quantification Using Infrared Spectroscopy, Ryley A. Burton-Tauzer
Cal Poly Humboldt theses and projects
A growing interest in sustainable waste management and the implementation of new policies have prompted a shift towards alternative resource recovery methods for organic waste, including food waste. To effectively assess alternative food waste treatment scenarios, it is important to evaluate the life cycle impacts associated with each scenario. The storage phase of food waste, encompassing its accumulation in kitchens, and storage in bins for collection and transportation, has been overlooked as a source of greenhouse gases in previous studies. This investigation aimed to identify the greenhouse gases emitted during the initial five-day period of low-oxygen storage. An open dynamic …

Cell Signaling And Stress Response In The Yeast Saccharomyces Cerevisiae: A Study Of Snf1, Scott E. Arbet Ii
Graduate Theses, Dissertations, and Problem Reports
Saccharomyces cerevisiae are yeast that are unicellular eukaryotic organisms that are well studied as a model organism for understanding fundamental cellular processes. The ability of yeast to sense nutrient availability is crucial for their survival, growth, and reproduction. Yeast cells use various mechanisms to sense and respond to nutrient availability, including transporter-mediated uptake, receptor-mediated signaling, and sensing of metabolites. The subcellular localization of nutrient-sensing components is crucial for yeast function in nutrient sensing and signaling. Protein complexes, such as the AMP-activated protein kinase (AMPK) pathway, in nutrient sensing and response, as well as the downstream effects of these pathways …
Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, 2023 The University of Akron
Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell
Williams Honors College, Honors Research Projects
Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.
Distribution Patterns Of Allorhizobium Vitis In Missouri Vineyards And Non-Vineyard Soils, 2023 Missouri State University
Distribution Patterns Of Allorhizobium Vitis In Missouri Vineyards And Non-Vineyard Soils, Jacquelyn M. Wray
MSU Graduate Theses
Crown gall disease causes significant economic loss to the grape and wine industry. Preventive strategies are most effective for mitigating the loss of grapevines in vineyards, as there is no known cure for this disease. The bacterium Allorhizobium vitis carrying a tumor-inducing (Ti) plasmid is the causative agent. A. vitis bacteria live systemically in the grapevine before causing visible symptoms and can survive in residual plant tissues and soil for more than two years. Diagnostic methods have been developed to detect A. vitis bacteria in grapevines and soil. However, more reliable, specific, and high-throughput diagnostics are still needed for screening …
The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, 2023 Georgia Southern University
The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, Derick A. Anglin
Electronic Theses and Dissertations
Hamstring injuries are common muscle-skeletal injuries with a high recurrence rate. While unmodifiable risk factors (e.g., previous injury) vary, recent evidence has questioned the utility of eccentric exercise in preventing hamstring strains. Furthermore, whether eccentric exercise can transfer to sprinting’s kinetic and kinematic requirements is of question. Therefore, this investigation examines exercise tempo (fast vs. slow eccentric phase), movement strategy (bilateral vs. unilateral), and external load characteristics (coupled vs. independent) bias concentric (CON) and eccentric (ECC) biceps femoris (BF) mean electromyography (mEMG). METHODS: Twenty college-aged students aged 18 – 33 (M = 23.4, SD = 3.12 years) with …

Investigation To Examine The Profile Of Auditory Brainstem And Hearing Thresholds Using Tone Burst Audiometry Brainstem Response In A Preclinical Migraine Model, Megan Huelsing
MSU Graduate Theses
Migraine is a disabling neurological disease that is characterized by prominent auditory symptoms, including hyperacusis, which is defined as extreme sensitivity to sounds. The goal of this study was to investigate changes in hearing sensitivity and neural changes in the brainstem by measuring neural activity of the auditory brainstem in an established preclinical model of chronic migraine. To induce a chronic migraine state within the trigeminal system, male and female Sprague Dawley rats were subjected to three known human risk factors including neck muscle tension and REM sleep deprivation that promote latent sensitization, and exposure to a pungent odor, which …
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, 2023 Missouri State University
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
MSU Graduate Theses
The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …

Cul3 Negatively Regulates Nlrp12-Mediated Inhibition Of The Canonical Nf-Κb Signaling Pathway, Inyeong Lee
MSU Graduate Theses
Nod-like receptor family pyrin domain-containing protein 12 (NLRP12) is mainly known for its inhibitory function on NF-κB signaling in innate immune cells, and more recently, for its ability to regulate chemokine signaling and ubiquitination of the immune receptor RIG-I. Through a yeast 2-hybrid screen, the Lupfer lab previously discovered that NLRP12 interacts with other ubiquitin-associated proteins including Cullin 3 (CUL3) and RING finger protein 2 (RNF2). This research was conducted to mainly investigate the interaction between NLRP12 and CUL3 in human cells and examine the role in regulating NF-κB signaling. Previously, co-immunoprecipitation, followed by western blot analysis, and confocal microscopy …
Understanding And Targeting The Immunosuppressive Tumor Microenvironment, 2022 The Texas Medical Center Library
Understanding And Targeting The Immunosuppressive Tumor Microenvironment, Li Cai, Li Cai
Dissertations & Theses (Open Access)
Immune checkpoint inhibitors (ICIs), such as anti-PD1/PD-L1 and anti-CTLA-4, have shown impressive antitumor efficacy by improving the activity of T cells. While these inhibitors work in many patients with various cancer types, they have minimal or no effect in many more patients. Mounting evidence indicates that, besides current known immune checkpoints, other immunosuppressive components in the tumor microenvironment (TME) need to be targeted to elicit the full immune responses.
Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immunosuppressive myeloid cells that are involved in cancer progression and therapeutic resistance. In this work, we demonstrated the essential role of MDSCs …
Dpc29 Promotes Mitochondrial Translation Post-Initation In Saccharomyces Cerevisiae, 2022 Rowan University
Dpc29 Promotes Mitochondrial Translation Post-Initation In Saccharomyces Cerevisiae, Kyle Andrew Hubble
Graduate School of Biomedical Sciences Theses and Dissertations
Although the cytosolic and bacterial translation systems are well studied, much less is known about translation in mitochondria. In the yeast Saccharomyces cerevisiae, mitochondrial gene expression is predominately regulated by translational activators. These regulators are thought to promote translation by binding the elongated 5’-UTRs on their target mRNAs. Since mammalian mitochondrial mRNAs generally lack 5’-UTRs, they must regulate translation by other mechanisms. As expected, most yeast translational activators lack orthologues in mammals. Recently, a mitochondrial gene-specific translational activator, TACO1, was reported in mice and humans. To better define its role in mitochondrial translation I examined the yeast TACO1 orthologue, DPC29. …

Integrin adhesion receptors provide links between extracellular ligands and cytoplasmic signaling. Multiple kinases have been found to directly engage with integrin β tails, but the molecular basis for these interactions remain unknown. Here, we assess the interaction between the kinase domain of p21-activated kinase 4 (PAK4) and the cytoplasmic tail of integrin β5. We determine three crystal structures of PAK4-β5 integrin complexes and identify the PAK-binding site. This is a region in the membrane-proximal half of the β5 tail and confirmed by site-directed mutagenesis. The β5 tail engages the kinase substrate-binding groove and positions the non-phosphorylatable integrin residue Glu767 at …
