Tissue And Sex-Specific Rna Editing During Induced Acute Inflammation, Claire E. Nichols
Tissue And Sex-Specific Rna Editing During Induced Acute Inflammation, Claire E. Nichols
MSU Graduate Theses
A-to-I RNA editing is a process where select adenosine (A) nucleotides are deaminated by an editing enzyme, ADAR, to become inosines (I) in RNA transcripts. RNA editing can affect the sequence of the encoded protein and the regulation of the RNA. ADAR1 also plays a role in regulating innate immunity and its expression is upregulated during inflammation. Current data on the effects of increasing ADAR1 on RNA editing is limited, and most studies are completed only in male animals. We are interested in expanding RNA editing data to include female animals. Lipopolysaccharide (LPS) was used to induce acute inflammation and …
Intrasexual Territoriality, Degree Of Aggression, And Duet Function In The Carolina Wren (Thryothorus Ludovicianus), Danny Zapata
Intrasexual Territoriality, Degree Of Aggression, And Duet Function In The Carolina Wren (Thryothorus Ludovicianus), Danny Zapata
MSU Graduate Theses
Territorial behavior is fundamental for the reproductive success of many species. In many monogamous birds, mated pairs defend year-round territories from conspecifics. Males and females often participate in such interactions in a seemingly cooperative fashion. Furthermore, many of them have developed complex vocal interactions known as duets, in which one member of a pair overlaps its partner’s song in a more or less coordinated fashion, apparently to cooperate in territory defense. However, males and females often respond differently depending on the sex of the intruder; they differ in the degree and mode of aggression displayed during these interactions, and the …
Analysis Of Root System Architecture And Qtl Identification In Grapevines, Sujan Thapa
Analysis Of Root System Architecture And Qtl Identification In Grapevines, Sujan Thapa
MSU Graduate Theses
The root system of the plant plays a vital role in water and nutrient uptake. Native North American grapevines adapted to a broad range of climatic and soil conditions, which led to the evolution of diverse root system architecture (RSA) within the Vitis genus. Despite the importance of RSA in viticulture, little is known about the genetic basis of the RSA in grapevine. I used novel root phenotyping tool, RhizoVision Analyzer to characterize the root system of 208 genotypes of an F1 grapevine progeny obtained from a cross between Vitis rupestris Scheele B38 and Vitis riparia Michx. HP-1. Dormant …
Activity Patterns Among Head-Started Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Parker R. Golliglee
Activity Patterns Among Head-Started Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Parker R. Golliglee
MSU Graduate Theses
In contrast to many species of aquatic turtle, Alligator Snapping Turtles (Macrochelys temminckii) are putatively nocturnal. Data supporting this assertion are chiefly anecdotal, however, and two recent studies cast doubt on this generalization. Differences in activity patterns may be related to variability in temperature and photoperiod across the species’ range and may be influenced by ontogenetic changes, as well. To assess this, I equipped juvenile Alligator Snapping Turtles spanning a range of different ages with activity data loggers. I used 4-year-old turtles were to measure latitudinal differences in activity which were reared in hatchery ponds spanning the species’ …
A Comparison Of The Magnitude Of The Mental Health Benefits Of Exercising Outdoors Vs Exercising Indoors: A Review, Greta M. Rueschmann
A Comparison Of The Magnitude Of The Mental Health Benefits Of Exercising Outdoors Vs Exercising Indoors: A Review, Greta M. Rueschmann
MSU Graduate Theses
Many people in the United States suffer from poor mental health which can lead to suicide, self-harm, or negative effects on job performance and relationships. Not everyone can afford traditional therapy nor feels comfortable with it. With a greater emphasis placed on taking care of one’s mental health during the COVID-19 pandemic, there should also be a greater emphasis placed on finding alternative types of therapy that can be matched to individuals based on their personalities and preferences. One such alternative is outdoor exercise. This review was conducted to examine whether exercising or performing physical activity outdoors results in greater …
The Role Of The Host Factor Sptbn1 In Hiv-1 Infection Of Microglial Cells, Marc Gordon Havlicek
The Role Of The Host Factor Sptbn1 In Hiv-1 Infection Of Microglial Cells, Marc Gordon Havlicek
MSU Graduate Theses
HIV-1 is the etiological agent that cause AIDS. Since the 1980’s when HIV-1 was discovered, much has been discovered, however a cure for HIV-1 has eluded researchers. Effective therapeutics do exist but can have adverse side effects including HAND/HAD which leads to neurodegeneration in patients regardless of viral suppression. One area of research that holds the possibility of discovering new viral targets and therapeutics is host factor interaction within the replication process. One host factor that can cause a decrease in HIV-1 infectivity is SPTBN1. SPTBN1 is a cytoskeletal protein that was shown to bind to the capsid and nucleocapsid …
Effects Of Lemongrass Essential Oil On Galleria Mellonella Hemocytes, Kyndra Chastain
Effects Of Lemongrass Essential Oil On Galleria Mellonella Hemocytes, Kyndra Chastain
MSU Graduate Theses
In modern agriculture, the use of pesticides is unavoidable. However, improper use has resulted in pest resistance and negative impacts on the environment and human health. Changes are needed in the agricultural industry to account for the damage already caused. Researchers have turned to essential oils as key ingredients for potential biopesticides, with some mixtures already on the market. Most studies involving essential oils and a pest’s response concentrate on mortality or interruptions in development during and between life stages. My study, however, focused on immune responses; specifically, lemongrass essential oil’s impact on Galleria mellonella. Such responses include a …
Effects Of Sex And Reproductive Condition On Behavior Of Southern Red-Backed Salamanders: Activity, Agonistic Behavior And Escape Velocity, Megan N. Mosier
Effects Of Sex And Reproductive Condition On Behavior Of Southern Red-Backed Salamanders: Activity, Agonistic Behavior And Escape Velocity, Megan N. Mosier
MSU Graduate Theses
Producing and carrying eggs is energetically costly and therefore can affect behavior. Female Southern Red-backed Salamanders (Plethodon serratus) in the Ozarks reproduce biennially, and so during the reproductive season some females are gravid and some are non-gravid. In this study, we compared the exploratory and aggressive behaviors of gravid females, non-gravid females, and males, as well as the escape velocities of each sex class. In exploratory trials, sex did not affect distance travelled, but gravid females and males showed shorter latencies to move than non-gravid females during the winter. During the aggression trials, individuals were subjected to a …
Decomposition And Macroinvertebrate Shredder Colonization Of Autumnal Shed Sycamore Leaves In Mining-Contaminated Streams, Leslie Marie Hatch
Decomposition And Macroinvertebrate Shredder Colonization Of Autumnal Shed Sycamore Leaves In Mining-Contaminated Streams, Leslie Marie Hatch
MSU Graduate Theses
Leaf decomposition in streams is an important ecological function facilitated by bacteria, fungi, and macroinvertebrates. Metal contamination can decrease leaf decomposition rates and reduce macroinvertebrate abundance and diversity. In the current study, I focused on mining-contamination in well-buffered streams in two different Missouri mining districts with varying extents of mining contamination, Big River and Pierson Creek. I measured decomposition rates of sycamore leaves, and abundance and diversity of macroinvertebrate shredders in leaf pack experiments with a full-factorial design to determine the effects of metal contamination of leaves and stream substrates. Comparisons were made between leaf packs upstream and downstream of …
Evaluating The Impact Of Off-Farm Decisions On Federal Government Program Utilization And Financial Success For Missouri's Beginning Farmers, Lyndsey Ann Parker
Evaluating The Impact Of Off-Farm Decisions On Federal Government Program Utilization And Financial Success For Missouri's Beginning Farmers, Lyndsey Ann Parker
MSU Graduate Theses
Farmers and ranchers will have to increase production by approximately 70% by the year 2050 according to the American Farm Bureau Federation (2017). People in the agriculture industry face several challenges from start-up costs to limited land availability (Ahearn, 2011). There are federal and state government programs available to assist with some of these challenges but bring their own hardships as well. This study measures off-farm decisions that affect financial performance and utilization of government programs for Missouri’s farmers and ranchers. Three types of financial performance of Missouri farms are prioritized in this study, liquidity (current ratio), solvency (debt-to-asset ratio), …
A Study Of Cobalt (Iii) Oxide Nanoparticle Delivery Of Sirna Molecules Directed Against Signaling Intermediates Of The P2y2 Receptor, Rachel Blair Stroud
A Study Of Cobalt (Iii) Oxide Nanoparticle Delivery Of Sirna Molecules Directed Against Signaling Intermediates Of The P2y2 Receptor, Rachel Blair Stroud
MSU Graduate Theses
G protein-coupled receptors are evolutionarily ubiquitous sensors of extracellular signals, propagating intracellular signal cascades through heterotrimeric G proteins. P2Y2 receptors are GPCRs which are activated by extracellular nucleotides to mediate signaling cascades via Gαq coupling. Many GPCRs are subject to a common mechanism for signal termination involving phosphorylation of the C-terminal tail followed by β-arrestin binding and subsequent endocytic internalization of the complex. This effect has been described for the P2Y2 R in the 1321N1 astrocytoma cell line, and UTP-induced activation and desensitization profiles have been previously defined. There is need to develop molecular vehicles for safe and …
Effects Of Natural Products On Inflammation, Riley Ann Nadler
Effects Of Natural Products On Inflammation, Riley Ann Nadler
MSU Graduate Theses
Chronic inflammation is characterized by infiltration of inflammatory cells such as macrophages and lymphocytes into the tissue where they produce inflammatory cytokines that contribute to tissue damage. Worldwide, 3 out of 5 people die due to chronic inflammatory diseases like cardiovascular diseases, obesity, diabetes, and cancer. Since it is well-documented that diet and metabolism are key mediators of inflammation, I investigated the effects of dietary lectins on inflammatory cytokine production and the ability of sodium pyruvate, a metabolite, to decrease inflammation. In chapter 1, I examined the effect that lectins from either Triticum vulgaris (common wheat) or Phaseolus vulgaris (common …
Testing The Impact Of A Silencing Suppressor On Infectivity Of Grapevine Vein Clearing Virus Infectious Clone In Nicotiana Benthamiana, Wen Zhao
MSU Graduate Theses
Grapevine vein clearing virus (GVCV), the first DNA virus of the Badnavirus genus discovered in grapevines, is closely associated with grapevine vein-clearing disease. Through earlier research, Koch's postulates were partially met: GVCV was in all diseased plants; GVCV was introduced into a healthy grapevine through grafting and by aphids and caused the disease. However, more shreds of evidence are required to fulfill the last postulate, the same virus must be reisolated from the inoculated diseased grapevine (1). A full-length infectious clone of GVCV was previously constructed to provide evidence; however, its infectivity was not consistent. Therefore, the goal …
Public Perceptions Of Human Physical Interactions, Exhibition, And Conservation Of Tigers And Cheetahs, Abbie Knudsen
Public Perceptions Of Human Physical Interactions, Exhibition, And Conservation Of Tigers And Cheetahs, Abbie Knudsen
MSU Graduate Theses
Tigers and cheetahs are common in the pet trade, public exhibits, and hands-on encounters with the public. Poor regulation of these experiences has resulted in numerous incidents worldwide in which a person was seriously injured or killed by captive big cats. Additionally, concerns for animal welfare have been raised by industry professionals. Prior research on primates has demonstrated exposing people to photographs of cats in different backgrounds can influence their attitudes about animals in captivity, but no study has addressed whether visual images affect human attitudes toward big cats. I used a survey that asked a series of questions about …
Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books
Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books
MSU Graduate Theses
Garlic (Allium sativum L.) is grown on small and large scales worldwide. After harvesting, garlic undergoes a drying process for long-term preservation, called curing. Some producers cure with leaves intact, while others will remove and discard the leaves, curing only the bulbs. Due to the ability of plants to remobilize nutrients from leaves to underground storage organs, such as bulbs, the curing method of garlic may affect clove nutrient content. This study explores nutrient remobilization responses in garlic when cured with leaves intact compared to leaves separated from bulbs. Four cultivars of garlic, German White, Chesnok Red, Romanian Red, and …
The Comparison Of Three Different Fecal Egg Counting Techniques And Their Ability To Perform A Fecal Egg Count Reduction Test, Diana J. Summitt
The Comparison Of Three Different Fecal Egg Counting Techniques And Their Ability To Perform A Fecal Egg Count Reduction Test, Diana J. Summitt
MSU Graduate Theses
A comprehensive gastrointestinal parasite control program includes an understanding of common parasites, application of chemotherapeutic agents, as well as frequent and appropriate diagnostic testing. An effective control program is essential for facilities such as animal shelters, that deal with large populations of transient canines with unknown parasite exposure and deworming history. The identification of a sensitive flotation method to evaluate anthelmintic efficacy is critical in monitoring parasite populations for drug resistance. The objective of the current study was to compare three different fecal egg counting technologies and their ability to perform a fecal egg reduction test. The flotation techniques evaluated …
Intracellular Trafficking And Distribution Of Cd And Inp Quantum Dots In Hela And Ml-1 Thyroid Cancer Cells, Min Zhang
MSU Graduate Theses
The study of the interaction of engineered nanoparticles, including quantum dots (QDs), with cellular constituents and the kinetics of their localization and transport, has provided new insights into their biological consequences in cancers and for the development of effective cancer therapies. The present study aims to elucidate the toxicity and intracellular transport kinetics of CdSe/ZnS and InP/ZnS QDs in late-stage ML-1 thyroid cancer using well-tested HeLa cells as a control. The XTT viability assay showed that ML-1 cells, and non-cancerous mouse fibroblast cells, exhibit no viability defect in response to these QDs, whereas HeLa cell viability decreases. These results suggest …
Elucidating The Role Of Hemodynamic Force In Regulating The Attachment Of Vascular Smooth Muscle Cells (Vsmcs) To Maturing Vessels During Mouse Embryonic Development, Israt Jahan
MSU Graduate Theses
Blood vessel maturation is characterized by the recruitment and attachment of vascular smooth muscle cells (vSMCs) around immature blood vessels, which ultimately form the tunica media. Improper maturation can lead to vascular birth defects ranging from minor birthmarks to lethal brain aneurysms. Previously, our lab demonstrated that hemodynamic force plays an important role to regulate vSMCs recruitment from neighboring low-flow to high-flow vessels followed by the attachment of these vSMCs to the high-flow vessels. To understand the reason for the preferred attachment of vSMCs to high-flow vessels, instead of low-flow vessels, I hypothesize that hemodynamic force modulates the expression of …
Largemouth Bass In The Upper Mississippi River: An Evaluation Of Management Strategies And Understanding Potential Factors Influencing Dynamic Rate Functions, Kylie Beth Sterling
Largemouth Bass In The Upper Mississippi River: An Evaluation Of Management Strategies And Understanding Potential Factors Influencing Dynamic Rate Functions, Kylie Beth Sterling
MSU Graduate Theses
The Upper Mississippi River (UMR) supports ecologically and economically important commercial and recreational fisheries. One recreational fishery in the UMR is the Largemouth Bass fishery. Recreational fisheries can be effectively managed using information on population dynamics, though little is known about Largemouth Bass population dynamics in large river ecosystems. Therefore, the objectives of this study were to 1) evaluate recruitment, growth, and mortality of three Largemouth Bass populations in the UMR, specifically within Pools 4, 8, and 13, and 2) to use those estimates of recruitment, growth and mortality to inform exploitation models to evaluate best management practices for each …
Further Investigation Of The Initiating Mechanism Of The Type I Collagen Glomerulopathy, Matthew James Freese
Further Investigation Of The Initiating Mechanism Of The Type I Collagen Glomerulopathy, Matthew James Freese
MSU Graduate Theses
The progressive accumulation of collagen and other extracellular matrix proteins in the renal mesangium results in fibrosis, glomerulosclerosis, and eventual renal failure. Mice deficient in integrating α2(I) collagen into the type I collagen structure, termed Col1a2-deficient mice, model kidney fibrosis through the condition Type I Collagen Glomerulopathy, because homotrimeric type I collagen accumulates extracellularly in the mesangium of renal glomeruli. Accumulation of homotrimeric type I collagen compresses blood vessels in glomeruli, which reduces filtration, increases pressure, and results in fibrosis. Picrosirius red (PSR) staining was used on Col1a2 deficient and wildtype mice to evaluate collagen deposition. Histological evaluation and …
Investigation Of The Neuroprotective Effects Of Grape Seed Extract On Trigeminal Ganglion Primary Cultures, Sophia Rose Antonopoulos
Investigation Of The Neuroprotective Effects Of Grape Seed Extract On Trigeminal Ganglion Primary Cultures, Sophia Rose Antonopoulos
MSU Graduate Theses
Migraine and temporomandibular disorders (TMD) are prevalent, debilitating orofacial pain conditions involving peripheral and central sensitization of the trigeminal system. The pro-inflammatory neuropeptide calcitonin gene-related peptide (CGRP), which is synthesized and secreted from trigeminal ganglion neurons, is implicated in the underlying pathology of migraine and TMD. Secreted CGRP modulates the excitability state of neurons and glial cells that express CGRP receptors. Recent studies from our lab in preclinical models of migraine and TMD have provided evidence that dietary supplementation with a proanthocyanin-enriched grape seed extract (GSE) inhibits trigeminal pain signaling. The effect of GSE was blocked by an antagonist of …
Identification Of A Novel Protein Interaction That Elucidates The Mechanism Of Idiopathic Recurrent Miscarriages In Women With Nlrp2 Mutations, Nayeon Son
MSU Graduate Theses
The protein NOD-Like receptor pyrin domain containing 2 (NLRP2) is one member of a larger family of protein receptors that plays an important role in our innate immune system. In humans, the NLR family consists of 22 proteins. However, only about a half of NLRs’ functions are known, but many are pro-inflammatory, causing inflammation. NLRP2 has been identified to be a maternal effect gene regulating early embryo development in idiopathic recurrent miscarriages. In previous studies, mutations in the NLRP2 gene resulted in genetic maternal imprinting disorders due to NLRP2 regulating DNA methylation. However, the exact mechanisms involved in recurrent miscarriages …
Spatial And Temporal Heterogeneity Of Hyporheic Invertebrates In An Ozark Stream, David Fleshman
Spatial And Temporal Heterogeneity Of Hyporheic Invertebrates In An Ozark Stream, David Fleshman
MSU Graduate Theses
The hyporheic zone (HZ), an ecotone between surface water and groundwater in streams, provides extensive but underappreciated habitat for invertebrates in alluvial systems like the gravel-bed streams common in the Ozark highlands. Relative to its importance as a habitat, little is known about spatial distribution and response to disturbance by invertebrates in the HZ. In riffle-pool systems, surface water typically enters the HZ at the head of riffles (downwelling) and returns to the surface at the tail of riffles (upwelling). Previous research has found differences in invertebrate communities and environmental variables between upwelling and downwelling zones, but results have been …
