Cost Burden Of Social Isolation For Wheelchair Users In Louisville, Kentucky., Connie Light May 2018

Cost Burden Of Social Isolation For Wheelchair Users In Louisville, Kentucky., Connie Light

Electronic Theses and Dissertations

Background: Social isolation is an important predictor for poor health status, chronic diseases, and healthcare utilization and costs. There is a growing number of Americans with one or more disabilities, and evidence suggests that many are also socially isolated. This is especially true for those with immobility, as the built environment including housing structures are not universally designed to be accommodating. Immobility describes those who use walkers, canes, or wheelchairs, with the latter suffering the most impact. The cost of social exclusion can be measured by the exacerbation of disease in wheelchair users, whose fragile health status and social networks …


Exercise Preconditioning And Tfam Overexpression Diminish Skeletal Muscle Atrophy., Nicholas Todd Theilen May 2018

Exercise Preconditioning And Tfam Overexpression Diminish Skeletal Muscle Atrophy., Nicholas Todd Theilen

Electronic Theses and Dissertations

This dissertation is an analysis of skeletal muscle atrophy and a molecular assessment of potential preventative treatments. Chapter I begins with a background of skeletal muscle atrophy along with an analysis of associated molecular pathways. Here, we discuss how skeletal muscle atrophy is the consequence of protein degradation exceeding protein synthesis and can occur when a muscle is abnormally disused. The development of therapies prior to skeletal muscle atrophy settings to diminish protein degradation is scarce and could be useful to prevent negative clinical outcomes of patients who must unload and disuse musculature over extended periods. Mitochondrial dysfunction is associated …

A Role Of Vitamin B2 In Reducing Amyloid-Beta Toxicity In A Caenorhabditis Elegans Alzheimer’S Disease Model, Muhammad Tukur Ameen May 2018

A Role Of Vitamin B2 In Reducing Amyloid-Beta Toxicity In A Caenorhabditis Elegans Alzheimer’S Disease Model, Muhammad Tukur Ameen

Electronic Theses and Dissertations

Alzheimer’s disease (AD) is associated with amyloid-beta peptide deposition and loss of mitochondrial function. Using a transgenic C. elegans AD worm model expressing amyloid-beta in body wall muscle, we determined that supplementation with either of the forms of vitamin B2, flavin mononucleotide (FMN) or flavin adenine dinucleotide (FAD) protected against amyloid-beta mediated paralysis. FMN and FAD were then assayed to determine effects on ATP, oxygen consumption, and reactive oxygen species (ROS) with these compounds not significantly improving any of these mitochondrial bioenergetic functions. Knockdown of the daf-16/FOXO transcriptional regulator or the FAD synthase enzyme completely abrogated the …

Diet Breadth Evolution And Diversification Of A Generalist Insect Herbivore, Mayra Cadorin Vidal Jan 2018

Diet Breadth Evolution And Diversification Of A Generalist Insect Herbivore, Mayra Cadorin Vidal

Electronic Theses and Dissertations

Insect herbivores are one of the most diverse groups of multicellular organisms, and the vast majority are specialists, which feed on only a few plant species. The factors that cause some herbivores to be specialists and others to be generalists are still unclear. It is known that the selective forces from natural enemies (top-down) and the host plants (bottom-up) influence an herbivore's diet breadth. In my meta-analysis evaluating the relative important of top-down and bottom-up forces on insect herbivore fitness, I found that herbivores usually have greater performance on better quality plants and in the absence or reduction of enemy …


Social Conflict On The Seas: Links Between Overfishing-Induced Marine Fish Stock Declines And Forced Labor Slavery, Jessica L. Sparks Jan 2018

Social Conflict On The Seas: Links Between Overfishing-Induced Marine Fish Stock Declines And Forced Labor Slavery, Jessica L. Sparks

Electronic Theses and Dissertations

Despite media attention detailing labor abuses in fisheries, social-ecological systems research has largely failed to consider whether fish stock declines could be contributing to increases in forced labor slavery. Empirical fisheries data suggests, though not a ubiquitous response to declining stocks, many vessels will fish longer, farther from shore, and deeper in waters to maintain yields. This effort intensification increases production costs, and Brashares et al. (2014), consistent with slavery theory, posited cheap and/or unpaid labor as an approach to offset increasing costs and continue harvesting fish species at a rate otherwise cost-prohibitive.

Using fuzzy cognitive mapping - a participatory, …

Tripartite Interactions Of Legumes With Arbuscular Mycorrhizal Fungi And Rhizobial Bacteria: Insight Into Plant Growth, Seed Yield, And Resource Exchange, Arjun Kafle Jan 2018

Tripartite Interactions Of Legumes With Arbuscular Mycorrhizal Fungi And Rhizobial Bacteria: Insight Into Plant Growth, Seed Yield, And Resource Exchange, Arjun Kafle

Electronic Theses and Dissertations

Under natural conditions, legumes, such as alfalfa (Medicago) and soybean (Glycine max) are colonized with arbuscular mycorrhizal (AM) fungi and rhizobial bacteria forming tripartite interactions. Legumes are important crop species due to their high nutritional and economic values. Most of the previous literatures focused on experiments with an individual symbiont: either AM fungi or rhizobial bacteria, but not with both symbionts at the same time, thus our current understanding of resource exchange in tripartite interactions is limited. It has been reported that AM fungi primarily provide phosphate (P), nitrogen (N), and other nutritional and non-nutritional benefits while rhizobial bacteria solely …

Electronic Theses and Dissertations

Two evaluations were conducted to evaluate the biological and economic production efficiency of retaining replacement females in a straight-bred Angus herd (HR) as opposed to purchasing crossbred replacements for a terminal sire production system (PR) where maximum maternal and individual heterosis is achieved. The first study was a comparison of the HR system versus PR system. It was modeled after a 100 hd, straightbred Angus cowherd that raises their own replacement females. The (NASEM, 2016) model was used to determine the required metabolizable energy (ME)/animal for each stage of production. Stages were broken into segments including weaning – d 28, …


Diversity Of Free – Living Nitrogen – Fixing Bacteria In Soil Of Sioux Prairie Of South Dakota, Nabilah Ali Alshibli Jan 2018

Diversity Of Free – Living Nitrogen – Fixing Bacteria In Soil Of Sioux Prairie Of South Dakota, Nabilah Ali Alshibli

Electronic Theses and Dissertations

There are only two natural ways by which molecular nitrogen can be available to support life, either by free-living or by symbiotic nitrogen fixing bacteria. The best studied diazotrophs form symbiotic associations with plants, primarily legumes and certain tree species, but little is known about how non-leguminous plants such as grasses obtain nitrogen in their environment. Natural prairies have few legumes, thus have less symbiotic nitrogen fixer interaction. This indicates presence of free-living nitrogen (FLN) fixation activity towards the balance of the N cycle. The objective of this study was to characterize the culturable diversity of free-living diazotrophs in native …

Genetic Component Effects Of Two Loci On Seed Dormancy, Awn, Low-Temperature Germination, Plant Height, And Flowering Time In Rice (Oryza Sativa L.), Ugur Korkmaz

Electronic Theses and Dissertations

Seed dormancy (SD) is an adaptive trait of both ecological and agricultural importance. Cereal crops have been selected for reduced SD to promote germination, which also caused the pre-harvest sprouting (PHS) problem in crop production. The previous research identified a set of quantitative trait loci (QTL) for SD, including qSD1- 2 and qSD8, in the conspecific weedy and cultivated rice (Oryza sativa). qSD1-2 carries a dormancy-enhancing allele from the cultivated rice and has a pleiotropic effect on plant height. qSD8 carries a dormancy-enhancing allele from the weedy rice and tightly links to qAL8 for awn length. The …

Study Of Anti-Proliferative Activity Of Cucurbitacins Inspired Estrone Analogs On Hepatocellular Carcinoma, Sara Elgazwi

Electronic Theses and Dissertations

Hepatocellular carcinoma (HCC) is considered the third leading cause of death from cancer. Overall survival rate is significantly low, due to the emerging resistance to chemotherapeutic agents and lack of selectivity. Recent studies have demonstrated that epidermal growth factor receptor (EGFR) is a promising molecular target for cancer therapy, especially HCC. Current studies showed that cucurbitacins are potent anticancer compounds which target EGFR. This prompted us to investigate the antiproliferative activity of novel cucurbitacins inspired estrone analogs (CIEA) against sensitive and resistant HepG2 cell lines. Anti-proliferation activity of 20 CIEA analogs were examined against HepG2 using MTT assay and showed …


Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez Jan 2018

Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez

Electronic Theses and Dissertations

Phytochemicals such as tannins included in dairy cow nutritional programs, as a natural feed additive, promise to improve rumen bypass protein and consequently reduce the feeding cost by decreasing the amount of CP needed in the ration. Additionally, if tannins are fed along with high quality protein sources, this could improve the AA profile reaching the small intestine and potentially improving health and performance of dairy cows. The black pepper, specifically its alkaloid piperine, is a nontoxic, natural dietary compound with a broad range of physiological activity. Lactating dairy cows ingesting these phytochemicals (tannin extracts and black pepper) will potentially …


Efficiency Of Utilizing Standardized Ileal Digestible Lys And Thr For Whole Body Protein Retention In Pregnant Gilts During Early, Mid And Late Gestation, Ron Aldwin Sapin Navales Jan 2018

Efficiency Of Utilizing Standardized Ileal Digestible Lys And Thr For Whole Body Protein Retention In Pregnant Gilts During Early, Mid And Late Gestation, Ron Aldwin Sapin Navales

Electronic Theses and Dissertations

In pregnant pigs, amino acid (AA) requirements represent the sum of those required for maintenance functions, protein retention and efficiency of utilizing AA intake for the aforementioned body processes. The NRC (2012) model assumed AA efficiency is constant across period of gestation; however this is not reflective of the changes in metabolic demand during gestation. Therefore, two experiments were conducted to evaluate the efficiency of utilizing SID Lys and Thr for whole body protein retention (kSIDLys and kSIDThr) in pregnant gilts during early, mid and late gestation. Three 12 d N-balance studies were conducted to represent different periods of gestation. …
