Severity Of Deficit In Skeletal Muscle Lipid Metabolism Invokes Unique Adaptive Responses In Dietary Lipid Intake And Absorption, Victoria Datta
Severity Of Deficit In Skeletal Muscle Lipid Metabolism Invokes Unique Adaptive Responses In Dietary Lipid Intake And Absorption, Victoria Datta
Masters Theses
Skeletal muscle plays a central role in whole-body lipid metabolism through mitochondrial and peroxisomal fatty acid oxidation (FAO). When skeletal muscle lipid metabolism is impaired, whole-body adaptations occur to maintain metabolic homeostasis. We hypothesized that limiting skeletal muscle lipid metabolism through mitochondria and/or peroxisomes would trigger adaptive responses to reduce dietary lipid intake and/or absorption with the most robust changes coinciding with deficit severity. Mice were generated with skeletal muscle-specific deletion of 1) carnitine palmitoyltransferase 1b (Cpt1bM-/-) to limit mitochondrial FAO, 2) peroxin 5 (Pex5M-/-) to impair peroxisomal FAO, and 3) both Cpt1b and Pex5 (DKO). Results were compared to …

Life-Stage Specific Predatory Efficiency Of 2 Generalist Predators Of Bemisia Tabaci (Hemiptera: Aleyrodidae), Itohan Aigbedion-Atalor, Abdelmutalab G. Azrag, Alvin M. Simmons, Jason M. Schmidt
All Peer-Reviewed Publications
Bemisia tabaci (Gennadius) is an economically damaging invasive pest to global vegetable production. Current management strategies rely heavily on insecticides, but increasing levels of resistance raise sustainability concerns. Therefore, strengthening integrated pest management (IPM) programs requires enhancing biocontrol through improved predator-pest interactions. Despite the well-established relevance of functional response modulation by multiple environmental factors, limited research has explored how plant traits and prey life stages interact to influence the efficiency of generalist predators in vegetable systems. To address this gap, we evaluated the functional responses of 2 adult generalist predators, Hippodamia convergens (Guérin-Méneville) and Geocoris punctipes (Say), against 3 nymphal …

Nmda Receptor Subunit Nmr-2 Regulates Pathogen-Induced Immune Responses Via The Nervous System In C. Elegans, Benson Otarigho, Jonathan Lalsiamthara, Alejandro Aballay
Faculty, Staff and Student Publications
Neural control of innate immunity must balance restraint of basal immune activity with rapid activation upon pathogen encounter. Glutamate, the primary excitatory neurotransmitter in the nervous system, has been implicated in several neurological disorders associated with inflammation, suggesting a potential link to immune regulation. However, how glutamatergic signaling contributes to immune balance remains unknown. Here, we demonstrated that the NMDA-type ionotropic glutamate receptor subunit NMR-2, a component of the NMDA receptor complex, acts in the

In addition, I collected baseline soil health data for all trials. Trials 1 and 2 were carried out at the Cal Poly San Luis Obispo Organic Farm using cabbage and broccoli as cash …
Movement And Space Use Of Weaned Northern Elephant Seal (Mirounga Angustirostris) Pups During Their First At-Sea Foraging Migration, Katie Saenger
Movement And Space Use Of Weaned Northern Elephant Seal (Mirounga Angustirostris) Pups During Their First At-Sea Foraging Migration, Katie Saenger
Master's Theses
The northern elephant seal (Mirounga angustirostris) is a marine mammal known for engaging in long foraging migrations at sea. Adult male northern elephant seals follow pathways along the western coast of North America towards Alaska and adult female northern elephant seals follow pathways to open ocean in the North Pacific. However, there is little information on weaned northern elephant seal pup foraging behavior during their first foraging migration. This lack of knowledge is significant because northern elephant seals have a mortality rate of >50% in the first year. This project aimed to better understand the at-sea migratory movement …

Updates To The Caniform Fauna (Carnivora, Caniformia) Of The John Day Formation, Oregon, Usa, John D. Orcutt, Kevin C. Talbott, Michael J. Monroe, Nicholas A. Famoso
Biology Faculty Scholarship
The John Day Formation of central Oregon preserves a diversity of Oligo-Miocene caniform carnivorans, many of which were first described from the formation. However, many historically important specimens lack detailed locality or stratigraphic information, complicating any analysis of faunal change through time. Here, we describe 16 new specimens of caniforms from the John Day Formation, most with precise stratigraphic information. We report multiple specimens of the amphicyonids Daphoenus Leidy, 1853, Paradaphoenus cuspigerus (Cope, 1878), and Temnocyon altigenis (Cope, 1878), all previously known from the formation. We also report the first definitive occurrence of the hesperocyonine canid Osbornodon Wang, 1994 from …

Immunomodulatory And Signaling Molecules From Plant-Associated Bacteria: Toll-Like Receptor 4 Agonist Adjuvants And Diketopiperazine-Mediated Communication, Marian Romaine
Dissertations, Theses, and Capstone Projects
Medicinal plants and their associated microbiomes constitute a rich source of bioactive natural products with applications in immunotherapy and microbial ecology. Herbal formulations have long been valued for safe immune enhancement, while bacterial signaling molecules govern community behaviors critical to pathogenesis, symbiosis, and environmental processes. Bacterial lipopolysaccharides (LPS) from plant-associated Gram-negative bacteria have emerged as potent TLR4 agonists, yet their endotoxic potential limits direct use, and diketopiperazines (DKPs) serve as versatile quorum-sensing mediators capable of modulating biofilms in mixed microbial systems.
The work in this thesis comprises two independent but complementary research strands. The first strand pursued the engineering of …

Human intolerance is a critical factor limiting both the distributions and populations of large carnivores. Using gray wolves as a case study, we synthesize a half-century of scholarship with the aims of clarifying the conceptual foundations of “tolerance” and integrating insights from across the social sciences. Specifically, we review longitudinal studies of attitudes toward wolves and show how trends vary across the populations examined. We then identify and discuss three complementary theories that help explain variation in tolerance across individuals, social groups, and societies: (1) Risk–benefit theories illuminate how perceptions of risks, benefits, and controllability shape individuals’ tolerance of carnivores; …

Dock7 Is A Novel Modifier Of Duchenne Muscular Dystrophy Pathology, Katherine English
Dock7 Is A Novel Modifier Of Duchenne Muscular Dystrophy Pathology, Katherine English
ETDs from 2020-2029
Duchenne muscular dystrophy (DMD) is a progressive, x-linked neuromuscular disorder affecting 1/5000 male births every year. DMD results from mutations in DMD, a critical structural protein within the muscle. In the absence of Dystrophin, the muscle degrades, increasing inflammation, destabilizing the cell membrane and going through constant cycles of regeneration which depletes the stem cell population. Over time, muscle tissue is replaced by fibrosis and adipose tissue, leading to loss of ambulation, respiratory and cardiac failure leading to death by early 20s. The standard of care for DMD patients is corticosteroid treatment. However, gene therapies have recently emerged which present …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali
Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

Elucidating The Role Of The Rnf20 Histone Modifier In Pancreatic Beta Cells, Tanya Hans Pierre
ETDs from 2020-2029
Diabetes is defined as a loss of functional beta cell mass. It is classically categorized into Type 1 Diabetes (T1D), immune-mediated beta cell destruction and Type 2 Diabetes, which is characterized by whole body insulin resistance alongside beta cell dysregulation. The incidence of diabetes worldwide has risen annually. Despite the presence of therapeutic interventions, diabetes’ heterogeneity can prompt ineffective glycemic control and the development of diabetes-associated comorbidities. For that reason, new approaches to glycemic control for individuals with diabetes are required. One approach to restore glucose homeostasis is beta cell replacement therapy, in which stem cells are programmed into beta-like …
Protein Glycosylation In Natural And Synthetic Minimal Genome Mycoplasmas, John Sanford
Protein Glycosylation In Natural And Synthetic Minimal Genome Mycoplasmas, John Sanford
ETDs from 2020-2029
Mycoplasmas are cell wall-less bacterial symbionts with remarkably streamlined genomes. Mycoplasmas offer two intriguing model organisms for studying concepts of minimal life. Mycoplasma genitalium has streamlined its genome to 580-kbp while maintaining virulence to suit its niche of parasitizing the human urogenital tract. The J. Craig Venter Institute has synthesized and transplanted a 543-kbp genome into a recipient cell, resulting in a non-pathogenic organism termed JCVI-syn3A. The conservation of a biological process in M. genitalium and JCVI-syn3A strongly implies an essential function in mycoplasmas, and potentially all life. Despite common thought of mycoplasmas being the simplest cells, much of their …

Marine Heatwaves And Fish Reproduction: Endocrine Responses In The Eurythermal Sheepshead Minnow (Cyprinodon Variegatus), Isabel Villafuerte
Master's Theses
Marine heatwaves associated with climate change are increasing in frequency and severity, posing significant threats to fish populations in shallow habitats such as estuaries and salt marshes. Because temperature is a primary regulator of fish reproduction, understanding how heatwaves affect reproductive physiology is critical for anticipating the biological consequences of ongoing climate change for coastal fishes. Here we examined how simulated heatwave conditions affect the reproductive hypothalamic-pituitary-gonadal (HPG) endocrine axis in the estuarine sheepshead minnow (Cyprinodon variegatus), a eurythermal fish well suited to studying thermal stress responses in estuarine environments. Adult sheepshead minnows acclimated to a daily oscillating …
Effects Of Hot Water Dipping And Sub-Zero Saline Chilling On The Microbial Safety Of Broiler Carcasses And Recycled Chilling Water, Elen Zhu
Master's Theses
Broiler meat became the most widely consumed meat within the United States and across the world in 2019. The trend of increasing broiler consumption is expected to continue due to affordability, health benefits, and production efficiency. To meet the growing demand of broilers, a substantial number of birds need to be produced and processed while minimizing bacteria contamination, water consumption and wastewater generation.
In this study, the microbial safety (mesophilic aerobic bacteria, coliforms, and Escherichia coli) of broiler carcasses and post-chill water (red water) was assessed, using innovative processing techniques and red water recycling. A total of 144 broilers …
Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick
Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick
Master's Theses
Iron deficiency (ID) affects over 2 billion individuals globally. Children under 5 are at increased risk of ID due to rapid growth and are especially vulnerable to its negative consequences because of iron’s essential role in cognitive development and immune maturation. ID is the leading cause of iron deficiency anemia (IDA), with IDA affecting approximately 40% of children in this age group. Antibiotic (abx) exposure is also prevalent during early life and may disrupt growth and through gut dysbiosis, with increasing use posing additional risk in younger populations. Geographically, there is overlap in regions with high anemia prevalence and those …
Assessing Nitrogen Leaching Risk In Organic Vegetable Production, Megan Widle
Assessing Nitrogen Leaching Risk In Organic Vegetable Production, Megan Widle
Master's Theses
Nitrogen (N) leaching is the primary driver of groundwater contamination in agricultural regions. On California’s Central Coast, Agricultural Order 4.0 regulates this risk by constraining field-level N balances (N applied minus N removed). However, the assumption that unrecovered N is lost via leaching may not hold in organic and regenerative systems that promote soil organic matter accumulation. This study evaluated whether measured N leaching aligns with estimates derived from partial N budgets in organic systems, and whether management practices (intercrops, cover crops, and reduced tillage) can mitigate leaching risk. Four field trials were conducted to investigate N dynamics in organic …
