The Response Of Naturally Regenerating Hardwood Seedlings To Post-Harvest Weed Control And Fertilization, Kevin Andrew Tomlinson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Current models to predict post-harvest success rely upon pre-harvest regeneration assessments, which rarely occur. Furthermore, these models lack management recommendations to improve regeneration success of naturally regenerating desired hardwood species following overstory removal. Factorial combinations of weeding and fertilization were randomly assigned to individual naturally regenerating black cherry (Prunus serotina Ehrh.), chestnut oak (Quercus montana Willd.), white oak (Quercus alba L.), and red oak (Q. rubra L., Q. velutina Lam., and Q. coccinea Muenchh.) seedlings in the spring of 2015, three growing seasons post-harvest. Factorial ANOVA models with size at treatment application as a covariate were developed and showed species-specific …

Characterization And Shelf-Life Of Soluble Protein Powder Derived From Silver Carp (Hypophthalmichthys Molitrix), Derek Warren
Graduate Theses, Dissertations, and Problem Reports (ETD)
Better management of current resources is one method to feed an ever growing population. Currently, sarcoplasmic proteins, water soluble proteins making up 25--30% of total protein in fish, are disposed of through municipal water treatment in surimi waste wash water. There is potential for the development of a simple method to reclaim and repurpose soluble protein from surimi wash water. The objective of this research was to 1) determine if processing temperature impacted protein recovery, 2) characterize the soluble protein powder, and 3) compare shelf stability to that of a similar protein powder (80% whey protein concentrate WPC). Separation temperature …
Exploring The Power Of County-Level Regional Classifications On Predicting Sex-Specific All-Cause Mortality In The United States, Julia Kay Wolf
Exploring The Power Of County-Level Regional Classifications On Predicting Sex-Specific All-Cause Mortality In The United States, Julia Kay Wolf
Graduate Theses, Dissertations, and Problem Reports (ETD)
Sex-specific mortality rates have been found to differ across regions of the United States; however, these areas are typically the broad Census Bureau regions (i.e., Midwest, Northeast, South, and West) that do not consider sociological factors known to affect health. By testing the predictive capabilities of theoretically driven regional classifications distinguished at county-level, I explore whether there are more accurate ways of assessing mortality differences across the United States. Specifically, I use the US Census Bureau divisions and regional groupings produced by Joel Garreau (1981) and Colin Woodard (2011) to predict sex-specific, age-adjusted, all-cause mortality for 2008-2012 (centered on 2010). …

Characterization Of The Immune Response To Lipopolysaccharide In Early Pregnant Ewes As A Model To Study Bacterial Infection Induced Embryonic Loss, Jessalyn Marie Hadfield
Graduate Theses, Dissertations, and Problem Reports (ETD)
An immunological balance has to be established during pregnancy that protects the mother yet tolerates the semi-allogenic fetus. To understand the innate immune response during bacterial infections that may cause early embryonic loss, a lipopolysaccharide (LPS) treated sheep model was used. Two objectives of this study were to examine if omega-3 PUFAs in the form of supplementary whole flaxseed could reduce the inflammatory response to an LPS challenge and to examine if there is a differential immune response to LPS in Suffolk and Dorset ewes. A total of 3 experiments were conducted; two investigating the effect of supplement and one …
Using Long-Term Records To Investigate Watershed Nitrogen Supply And Demand Dynamics At The Fernow Experimental Forest, West Virginia, Usa, Mark Benjamin Burnham
Using Long-Term Records To Investigate Watershed Nitrogen Supply And Demand Dynamics At The Fernow Experimental Forest, West Virginia, Usa, Mark Benjamin Burnham
Graduate Theses, Dissertations, and Problem Reports (ETD)
Fossil fuel combustion has caused elevated anthropogenic nitrogen (N) deposition onto forests in the northeastern United States since the middle of the 20th century, and has resulted in the supply of N exceeding the ecosystem N demand in many forests across the region. While the supply-demand imbalance is often attributed to elevated N inputs, a reduction in N demand may also make a significant contribution to diminished levels of N retention. Long-term records of N inputs, outputs, and stand dynamics at the Fernow Experimental Forest (FEF) in Tucker County, WV, provide a unique opportunity to study how changes in ecosystem …
The Effects Of Conjugated Linoleic Acid And Berberine Supplementation On Markers Of Allopurinol Activated Oxidative Stress In Broiler Chickens, Vincent Dartigue
The Effects Of Conjugated Linoleic Acid And Berberine Supplementation On Markers Of Allopurinol Activated Oxidative Stress In Broiler Chickens, Vincent Dartigue
Graduate Theses, Dissertations, and Problem Reports (ETD)
Selection for rapid growth in poultry can be linked to an exaggerated state of oxidative stress (reactive oxidative species, ROS). Reactive oxidative species are kept in balance by endogenous and exogenous antioxidants. Two compounds, conjugated linoleic acid (CLA) and berberine (BRB) a purified compound from plant root extract have been suggested to ameliorate antioxidant activity. A ten week study examined the effect of CLA and berberine supplementation on markers of oxidative stress in poultry. Broiler chickens (n=60) were equally divided into six groups; a control, a CLA group where half of the regular oil used in a standard was substituted …

Novel Treatment Strategies For Brain Metastases Of Breast Cancer, Afroz Shareef Mohammad
Novel Treatment Strategies For Brain Metastases Of Breast Cancer, Afroz Shareef Mohammad
Graduate Theses, Dissertations, and Problem Reports (ETD)
About 20-40% of advanced breast cancer patients will develop symptomatic brain metastases. Once the patients diagnosed with metastatic brain tumors, there is 80% mortality rate within one year. The presence of blood-brain barrier makes it difficult for drugs to reach the site of action in brain-related ailments. To overcome we came up with two strategies: First, we encapsulated the chemotherapy in a liposome and thereby significantly improving the plasma pharmacokinetics of chemotherapy. We also observed that tumor drug exposure significantly improved by liposomal formulation. This improvement in plasma drug pharmacokinetics and tumor drug accumulation after administration of the liposomal formulation …

Novel Mechanisms Controlling The Expression Of The Antidiabetic Hepatokine Fibroblast Growth Factor 21, Kimberly M. Alonge
Graduate Theses, Dissertations, and Problem Reports (ETD)
The incidence of obesity has increased at an alarming rate during the past thirty years. Current therapies for the treatment and prevention of obesity and metabolic syndrome are ineffective and/or produce undesirable side effects. Fibroblast growth factor 21 (FGF21) is a liver derived hormone that mediates adaptive changes in hepatic glucose and lipid metabolism by elevating energy expenditure and reducing lipid storage. Pharmacological administration of FGF21 analogs in both animal and human models induces striking reversals of obesity and type 2 diabetes. However, the activity of FGF21 analogs exhibit short half-lives in blood circulation and are unsuitable for current treatment. …

Bioacoustics And Behavior Of American Crocodiles In Belize, Miriam Boucher
Graduate Theses, Dissertations, and Problem Reports (ETD)
American Crocodiles (Crocodylus acutus) are large-bodied crocodylians broadly distributed throughout coastal and lowland wetlands in the Americas. Despite their being large, charismatic megafauna, the study of American Crocodile ecology is still lacking in many areas. As such we assessed the behavior and bioacoustics of American Crocodiles in Belize to address the paucity of data regarding these two facets of American Crocodile ecology. We conducted behavioral observations from three sites in the coastal zone of Belize. We categorized American Crocodile behavior and recorded activity duration for observed behaviors. In conjunction with behavioral data, we also assessed study sites to quantify the …

Phenotypic And Genotypic Characterization Of Lumbosacral Stenosis In Labrador Retrievers, Meenakshi Mukherjee
Graduate Theses, Dissertations, and Problem Reports (ETD)
Lumbosacral stenosis (LS) is a structural narrowing of the spinal canal in the canine lumbosacral spine. Large-sized working and sporting dog breeds such as Labrador retrievers are predisposed for reasons that are incompletely understood. Early diagnosis is essential for maximizing the quality of life, and minimizing the likelihood of early retirement in working dogs. Lumbosacral stenosis is usually considered to be a condition associated with degenerative changes observed with normal aging, however presence of the disease in young and middle aged working dogs has also been reported. This leads to the probable theory that some dogs in large breeds like …

Sleep Patterns And Associated Factors In Children And Adolescents With Inflammatory Bowel Disease, Margo M. Szabo
Graduate Theses, Dissertations, and Problem Reports (ETD)
Youth with inflammatory bowel disease (IBD) may be at increased risk for sleep difficulties due to the inflammatory nature of their disease. Moreover, previous research has demonstrated that children and adolescents with IBD experience impairment across a variety of psychosocial domains. However, the current literature has yet to examine the complex interplay between sleep, disease-related symptoms, and psychosocial factors such as mood and health-related quality of life in youth with both types of IBD (i.e., Crohn's disease and ulcerative colitis). Therefore, the purpose of this study was to examine sleep patterns and associated factors, including pain, disease activity, mood, and …

Identification And Functional Predication Of Long Non-Coding Rnas In Rainbow Trout And Cattle, Jian Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The simplest definition of a long noncoding RNA (lncRNA) is an RNA transcript larger than 200 nucleotides that does not encode for a functional protein product. This definition distinguishes lncRNAs from small regulatory RNAs such as microRNAs (miRNAs), short interfering RNAs (siRNAs), Piwi-interacting RNAs (piRNAs) and other short RNAs. They have emerged as a new class of regulatory transcripts in recent years. Recent advances in sequencing technologies have opened a new horizon for the identification and annotation of this class of RNAs in many species. With the increasing evidence supporting important roles of lincRNAs in diverse processes, a systematic catalog …
