Associations Among Task Self-Efficacy, Physical Activity And Subjective Wellbeing, Abigail M. Nehrkorn
Associations Among Task Self-Efficacy, Physical Activity And Subjective Wellbeing, Abigail M. Nehrkorn
Graduate Theses, Dissertations, and Problem Reports (ETD)
The physical and psychological health benefits resulting from physical activity engagement have been documented in previous literature, including the connection between physical activity and subjective wellbeing (SWB). Associations have also been found between task-related self-efficacy and physical activity, connecting these concepts to Bandura's Social Cognitive Theory (SCT; Bandura, 1982, 1997), such that retaining a higher belief in one's physical activity abilities has been associated with successful physical activity engagement. Previous literature has documented these separate associations, but not as much focus has been placed on examining task self-efficacy, physical activity, and SWB in one model, especially during the time of …
The Effect Of Ovine Peripheral Blood Mononuclear Cells On Haemonchus Contortus Larval Death In Vitro, Elizabeth Anne Shepherd
The Effect Of Ovine Peripheral Blood Mononuclear Cells On Haemonchus Contortus Larval Death In Vitro, Elizabeth Anne Shepherd
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gastrointestinal nematode parasitism is the greatest problem facing small ruminant livestock, largely due to development of anthelmintic resistance. Of particular concern is Haemonchus contortus, a hematophagous trichostrongylid that can lead to death in lambs or immunocompromised sheep. Some breeds of sheep are resistant to Haemonchosis, e.g. St. Croix (STC) hair sheep. St. Croix sheep have well-documented resistance and have been shown to develop a robust immune response, generating a rapid cellular response to larval stages that does not occur in susceptible sheep. Studies evaluating effects of mononuclear cells, including monocytes and lymphocytes, indicate that these cells dramatically reduce motility of …
Determination Of Strain Patterns Across The Root-Stem Transition Zone In Trees, Kenneth Edward Beezley
Determination Of Strain Patterns Across The Root-Stem Transition Zone In Trees, Kenneth Edward Beezley
Graduate Theses, Dissertations, and Problem Reports (ETD)
Trees are subjected to mechanical stressors, induced via dynamic (wind) and static (gravitational) forces, and must properly acclimate during their lifespan or face premature mortality. Resource allocation as a stress response is vital for tree survival, and can include the shedding of woody parts, adaptive growth, hormonal signaling cascades, and the initiation of energy transfer mechanisms. The strain resulting from stress intercepted by the canopy and transferred throughout the tree is of significant importance, not only for tree survival, but for the safety and well-being of the human population found in close proximity. As trees age and adapt to stressors …
Interleukin-15 Overexpression Attenuates Muscle Fatigue Associated With Murine Eo771 Mammary Tumors, Joseph F. Bohlen
Interleukin-15 Overexpression Attenuates Muscle Fatigue Associated With Murine Eo771 Mammary Tumors, Joseph F. Bohlen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Severe muscle wasting and muscle dysfunction (cachexia) are considered incurable complications associated with a wide variety of chronic diseases. This loss of function and severe wasting causes an increase in fatigue in cancer patients, leading to reduced motivation for daily activities, further reducing prognosis for recovery in these patients leading to a severe increase in morbidity. Recent work from our lab suggests Interleukin-15 (IL-15) induces a pro-oxidative state in the muscle, reducing fatigue and promoting a more oxidative phenotype. One proposed mechanism behind this is the observation that IL-15 promotes mitochondrial biogenesis, lending more mitochondria for oxidative metabolic processes. Therefore, …

Experiences Of Parents Of Children Adopted From Overseas: A Thematic Analysis Of Narratives, Ekaterina Anatolyevna Amarando
Graduate Theses, Dissertations, and Problem Reports (ETD)
Parents from the United States adopt more children from overseas than parents from any other country. There are numerous factors that play a role in the decision to adopt internationally, and most families remain highly satisfied with the adoption outcome (Adoption Institute, 2010). However, families with internationally adopted children face numerous challenges during their adoption journey, and generally report a higher utilization of professional services than biological families (Adoption Institute, 2010). In this study I utilized a qualitative research design to examine experiences of parents who adopted children from other countries. Thematic analysis of family narratives was employed to examine …
The Role Of Adenosine Monophosphate Activated Protein Kinase In Luteal Progesterone Production, Elizabeth Compton Bowdridge
The Role Of Adenosine Monophosphate Activated Protein Kinase In Luteal Progesterone Production, Elizabeth Compton Bowdridge
Graduate Theses, Dissertations, and Problem Reports (ETD)
Prostaglandin F2 alpha (PGF2&agr;) has in vivo luteolytic actions on the bovine corpus luteum (CL). Although PGF2&agr; is utilized extensively in livestock to synchronize estrus, its actions in vitro are controversial and do not always result in a reduction in progesterone (P4) secretion. The mechanism of action of PGF2&agr; is thought to involve activation of the phospholipase C-Ca2+ pathway. The luteolytic actions of PGF2&agr; are mediated through an elevation of cytosolic Ca2+ involving activation of protein kinase C (PKC). Expression of PKC isozymes and calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2) change as the CL develops to a mature stage. Either …
Polyploidy Affects Growth, Fillet Composition, And Fatty Acid Profile In Two Year Old Rainbow Trout, Oncorhynchus Mykiss, Jeremy Lynn Everson
Polyploidy Affects Growth, Fillet Composition, And Fatty Acid Profile In Two Year Old Rainbow Trout, Oncorhynchus Mykiss, Jeremy Lynn Everson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gonadal development is a dominant physiological process that alters growth and fat metabolism, thereby reducing fillet quality. Sterile, triploid (3N) female rainbow trout, generated by pressure-induced shock of zygotes 30 minutes after fertilization (3NP), are used to eliminate reduced growth and quality associated with gonadogenesis. However, this method does not produce 100% 3N offspring. Crossing a diploid (2N; fertile) female and a tetraploid (4N; fertile) male produces triploid offspring 100% of the time (3NC; sterile). This method is not widely used in the industry because it requires 4N brood stock. The current study examines growth, fatty acid composition, and fillet …

Spatializing The Soil-Ecological Factorial: Data Driven Integrated Land Management Tools, Travis Nauman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Soils form the dynamic interface of many processes key to the function of terrestrial ecosystems. Many soil properties both influence and are influenced by activity of flora and fauna. Interactions between soils, biota, and climate determine the potential ecosystem services that a given unique ecological site (ES) can support, and how resilient a site is to various pressures and disturbances. Soil data are needed to fully understand how these factors interact, but because this data is difficult to obtain, existing soil maps are sometimes not detailed enough to fully explore relationships. Environmental raster GIS data layers were used to increase …

Functional Analysis And Transcriptional Regulation Of Oocyte-Specific Nuclear Transporter Kpna7, Lei Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The finely orchestrated development and maturation of the oocytes has been the focus of many studies in which oocyte-specific genes essential for folliculogenesis and early embryonic development have been identified. Studies using knockout mice models of Nobox, Sohlh1, Sohlh2, Figla and Lhx8 have revealed that these oocyte specific transcriptional factors form networks in which they regulate the expression of each other and downstream targets. However, little is known about the mechanisms that control the nuclear transport of these essential factors in oocytes and early embryos. The nuclear envelope separates the nuclear and cytoplasmic compartment in the cell and uncouples transcription …
Soluble Oligomeric Abeta42 Affects Microglia Activation And Mitochondrial Respiration, Cong Tan
Soluble Oligomeric Abeta42 Affects Microglia Activation And Mitochondrial Respiration, Cong Tan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Microglia activation is associated with many neurodegenerative diseases such as Alzheimer's disease (AD). When activated, microglia cells change their morphology and become phagocytic. In the Alzheimer's brain, microglia cells play an important role in scavenging plaque-damaged cells and in clearing Abeta plagues. Soluble oligomeric Abeta (oAbeta) is capable to stimulate microglia activation. In AD brain, microglia cells accumulate around senile plaques as a hallmark of the pathology. Recently, we found that mitochondrial oxidative phosphorylation is affected in a dose-dependent manner in a microglia cell line (C8-B4) and primary rat glia cell. Mitochondrial basal, maximal and spare respiration capacities increase at …

Type 1 Diabetic Heart: Examination Of Mitochondrial Structure And Micrornas, Dharendra Thapa
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cardiac complications such as diabetic cardiomyopathy are the leading cause of morbidity and mortality in patients with diabetes mellitus. Dysfunctional mitochondria, an effect associated with cardiomyopathy, are central in the pathogenesis of type 1 diabetes mellitus. Cardiac mitochondria are comprised of two spatially located mitochondria including mitochondria located beneath the sarcolemma, termed subsarcolemmal mitochondria (SSM) and those located in between myofibrils, termed interfibrillar mitochondria (IFM). Mitochondrial subpopulations have been shown to respond differently to pathological and physiological stimuli as reported in a review published by our laboratory. IFM mitochondria are most impacted in a type 1 diabetic setting. Proteomic alterations …

The Effects Of Modest Improvement In Pellet Quality On Tom Turkey And Straight-Run Broiler Performance, With Focus On Experimental Design, Brian Gregory Glover
Graduate Theses, Dissertations, and Problem Reports (ETD)
Improving the crumble/pellet percentage of feed has been argued to be difficult to obtain in the commercial industry due to the necessity of feed mills producing adequate feed volume within a time constraint. Poultry research often utilizes small numbers of birds per pen or experimental unit that may affect the estimation of variance components, potentially producing pen performance metrics that are less valuable for industry guidance. In Experiment 1, diets were manufactured to maintain nutrient availability and vary only in crumble/pellet percentage (standard = 40% pellets, improved = 70% pellets). The two dietary treatments were then fed to Hybrid Converter …

First Year Biomass Production Following Application Of Various Size Strip Thinnings In A Young Hardwood Stand In West Virginia., Ashlee Martin
Graduate Theses, Dissertations, and Problem Reports (ETD)
Strip thinning can reduce stand density to promote better growth of residual trees and has potential to create a woody bioenergy feedstock in addition to enhancing and maintaining early successional habitat for wildlife. However, little research has been conducted on strip thinning within young hardwood stands to determine if these are viable attributes of strip thinning. The goal of this study was to assess the first year biomass production after strip thinning among three different cut strip widths (8 ft, 12 ft, and 16 ft) in a 22-year-old mixed mesophytic hardwood stand. Woody biomass production from stump sprouts and true …
A Novel Microbial Source Tracking Dna Microarray Used For Pathogen Detection In Environmental Systems, Xiang Li
Graduate Theses, Dissertations, and Problem Reports (ETD)
Pathogen detection and the identification of fecal contamination sources can be challenging in environmental and engineered treatment systems. Factors including pathogen diversity and ubiquity of fecal indicator bacteria hamper risk assessment and remediation of contamination sources. Therefore, a quick method that can detect and identify waterborne pathogens in environmental systems is needed. In this work, a custom microarray targeting pathogens (viruses, bacteria, protozoa), microbial source tracking (MST) markers, mitochondria DNA (mtDNA) and antibiotic resistance genes was used to detect over 430 selected gene targets in whole genome amplification (WGA) DNA and complementary DNA (cDNA) isolated from sewage and animal (avian, …
Calcium Enhanced Protein Recovery From Underutilized Aquatic Resources And Optimizing Protein Gelation Strategies Using Functional Ingredients, Ilgin Paker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Utilization of aquatic resources has rapidly gained importance. Traditional fish processing does not utilize the majority of the fish, thus generating large quantities of waste that impacts the economy, sustainability and environmental stress adversely. Protein can be extracted from underutilized sources such as silver carp and catfish using a pH shift processing method and incorporated into the human diet. Therefore, myofibrillar proteins were extracted from ground fish using different alkali solubilization and precipitation strategies. The efficacy of protein separation from lipids, and insoluble such as skin, fins, scales and bones were investigated and compared. Protein and lipid recovery yields were …
The Role Of Dynorphin In The Onset Of Puberty In Female Lambs, Justin Angelo Lopez
The Role Of Dynorphin In The Onset Of Puberty In Female Lambs, Justin Angelo Lopez
Graduate Theses, Dissertations, and Problem Reports (ETD)
The neural mechanisms underlying the onset of puberty are not well understood. In sheep, this process involves an increase in GnRH release due to decreased sensitivity to estrogen feedback. Because GnRH neurons do not express the relevant estrogen receptors, this pathway must contain interneurons. Neurons in the arcuate nucleus (ARC) of the hypothalamus that co-express kisspeptin (Kiss), neurokinin B, and dynorphin (DYN), i.e. KNDy neurons, play a critical role. Based on previous data, the overall hypothesis is that the prepubertal hold in GnRH/LH release results from reduced Kiss stimulation and heightened DYN inhibition in response to estrogen negative feedback. Two …
