Functional Characterization Of Phosphodiesterase-4a In Behavior And Obesity, Rolf T. Hansen Iii
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cognitive disorders such as depression, anxiety, and senescent-induced memory loss are a growing pandemic in the world. Anxiety is the most common psychiatric disorder in America, affecting upwards of 50 million people a year; depression has a lifetime prevalence of 20% of the population, and it's predicted pathological memory disorders such as Alzheimer's disease (AD) will reach exponential levels by the year 2050. While there are treatments for anxiety and depression, far less success has been reached with therapeutics for AD. Phosphodiesterases (PDEs) may be a potential novel target for future therapeutics aimed at combatting these psychiatric illnesses and neurodegenerative …
Effects Of Dietary Immunomodulation On Parasite Load In Commercial Crossbred Lambs, Rebecca Christine Price
Effects Of Dietary Immunomodulation On Parasite Load In Commercial Crossbred Lambs, Rebecca Christine Price
Graduate Theses, Dissertations, and Problem Reports (ETD)
Multidrug resistant gastrointestinal nematodes have left sheep producers with little options to control the detrimental effects of parasitism on their flocks. Immunomodulation has been used in many autoimmune diseases in an effort to downregulate the immune system and alleviate pathology. However, upregulation of immune responses by use of dietary immunosaccharides may allow parasite susceptible sheep to clear a Haemonchus contortus infection. To test this hypothesis, Dorset-Texel lambs were fed a ration including CelmanaxRTM at 1g/hd/day for one week prior to receiving an experimental infection of 10,000 L3 stage H. contortus larvae; which continued until the completion of the study. Increases …

Immune Related Gene Expression Of Parasite-Resistant Sheep During A Haemonchus Contortus Infection, Karen Nicole Sommers
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gastrointestinal nematode parasitism is a top health concern for sheep producers worldwide as traditional means of treatment are becoming less effective. Haemonchus contortus is of particular interest because it feeds on blood, causing significant pathological problems in the host. Certain breeds of sheep, like St. Croix, are more naturally resistant to parasitism. However, the underlying mechanisms that result in resistance are not fully understood. The following two experiments evaluated qPCR differential gene expression during the first ten days of a challenge H. contortus infection from lymph node and abomasal tissues. Experiment 1 evaluated 24 St. Croix hair lambs and 24 …

Stem Cell Matrix And Cartilage Regeneration, Jingting Li
Stem Cell Matrix And Cartilage Regeneration, Jingting Li
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cartilage defects caused by injuries of the knee affect about 900,000 Americans annually, resulting in more than 200,000 surgical procedures. Cartilage repair remains a major challenge due to its limited healing capacity. Current cell-based therapy using autologous chondrocyte implantation has been developed for decades and promising results have been observed in clinic. However, the shortage of autologous chondrocytes and their uncertain long-term effectiveness have led researchers to find alternative solutions. Stem cells from various tissues have been shown to be potential sources of chondrocytes. Among them, synovium-derived stem cells (SDSCs) have been suggested as tissue-specific stem cells for chondrogenesis. However, …

Country Schoolgirls: A Study Of Rural Women And The Rise Of Public Education, 1820-1914, Allyson Perry
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis explores the rise of public education, its influence on rural society, and the ways that farmwomen used schooling for a variety of purposes. Throughout the nineteenth century, more opportunities for women appeared as communities in the mountainous areas of West Virginia and Pennsylvania established free, public schools. With these social developments came an attempt to balance the public's perception of women's role in rural society. Administrators charged with implementing state-wide, public education had to set boundaries on women's advancement as they reacted to the public's changing ideas of women's proper role. Confronting these ideas set forth by administrators, …
Investigating Feeding Omega-3 Polyunsaturated Fatty Acids And/Or Soy Protein Isolate To Female Pck Rats On Polycystic Kidney Disease And Related Complications, Kaitlin Hope Maditz
Investigating Feeding Omega-3 Polyunsaturated Fatty Acids And/Or Soy Protein Isolate To Female Pck Rats On Polycystic Kidney Disease And Related Complications, Kaitlin Hope Maditz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Polycystic kidney disease (PKD) is a genetic disorder characterized by multiple benign cysts along the epithelial lining of the kidneys. As PKD progresses, cyst growth increases kidney volume, decreases renal function, and may eventually lead to end stage renal disease. In addition to renal manifestations, PKD patients are at risk of complications that include bone loss and polycystic liver disease (PLD). Currently, no genetic therapy or effective pharmacological treatments exist. Therefore, dietary intervention offers a potentially efficacious, cost-effective, and safe therapeutic option for PKD and PKD-related complications. Offering dietary treatment to attenuate PKD disease progression has the potential to improve …

Effects Of Maturation, Polyploidy, And Nutrition On Growth, Composition, And Gene Expression Within Fatty Acid Metabolism In Rainbow Trout, Meghan Lynn Manor
Effects Of Maturation, Polyploidy, And Nutrition On Growth, Composition, And Gene Expression Within Fatty Acid Metabolism In Rainbow Trout, Meghan Lynn Manor
Graduate Theses, Dissertations, and Problem Reports (ETD)
In many cultured fish species, such as salmonids, gonadal development occurs at the expense of stored energy and nutrients, including lipids. Mobilization of intramuscular lipid during gonadal development decreases fillet quality. The aquaculture industry induces triploidy to generate sterile individuals; however, differences in lipid metabolism of female diploid (2N) and triploid (3N) trout may alter fillet quality. In addition, there is concern that genetic selection for increased growth negatively impacts fillet quality and muscle lipid content. Research in these areas would aid in the development of better management practices for efficient food-fish production that optimizes product quality.;The goal of this …
Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Introduction: The unilateral posterior crossbite with a functional shift is one of the most common early adolescent malocclusions. It is caused by a transversely deficient maxilla, relative to the mandible, and results when the mandible shifts to one side to so the teeth can maximally interdigitate. This shift is thought to cause the contralateral condyle to move anteriorly, inferiorly, and medially within the TMJ. Much attention has been given recently to the affects of this functional shift on the condyles. An attempt is being made to determine if pathological position of the condyles can cause condylar signs or symptoms similar …
