An Evaluation Of Hibiscus Moscheutos Ssp. Lasiocarpos And Ipomoea Pandurata As Host Plants Of The Specialist Bee, Ptilothrix Bombiformis (Apoidea: Emphorini) And The Role Of Floral Scent Chemistry In Host-Selection., Melissa Diane Simpson

Theses

Ptilothrix bombiformis (Hymenoptera: Apoidea) is a specialist bee belonging to the tribe Emphorini. The emphorine phylogeny suggests that Convolvulacea is the ancestral plant family and independent evolutionary host-switches to several unrelated plant families have occurred. The role of floral scent has been well-characterized in pollination systems involving moths, butterflies, bumblebees, and honeybees, but little is known about how specialist bees mediate host selection, or how host-choice evolved in specialist bees. This research investigates the role of floral scent in host selection by P. bombiformis. Ptilothrix bombiformis has traditionally been classified as a Hibiscus (Malvaceae) oligolege. My research shows that it …

Thermoregulation Of Capsule Production Of Streptococcus Pyogenes Strain Hsc5, Trilce Michelle Galeas

Theses

Group A Streptococcus (GAS) is responsible for mild and common infections like tonsillitis and pharyngitis, and more serious invasive disorders like necrotizing fasciitis and glomerulonephritis. The ability to invade tissues is closely linked to the virulence factors expressed by the bacterium. Hyaluronic acid capsule expression is variable among all the strains in S. pyogenes and confers the capacity to evade the immune response. In a previous study, it was found that capsule production in CovR mutants was temperature-regulated, showing no capsule production at 37℃ but increased production was observed at 25℃. In this study, the objective is to find the …

Patterns Of Affiliation And Agonism In A Ringtailed Lemur, , Society: Tests Of The Socioecological Model And Other Hypotheses, Gena Christine Sbeglia

Theses

Efforts to understand the variation in primate social systems and the underlying social interactions have focused on both intrinsic and extrinsic factors. In the socioecological model, food distribution and abundance have been argued to be the primary influences on the social relationships and resulting social organization of primate groups. In the first part of this study, I examined the relationship of food and three additional factors (kinship, proximity, previous agonism) with patterns of affiliative and agonistic interactions in two semi-free ranging ringtailed lemur, , social groups (n=14) at Duke Lemur Center in Durham, NC.

Classifying The Fire Regime Condition Class For Upland Oak-Hickory Forests, Paul David Tikusis

Theses

Several reports of widespread establishment of mesophytic vegetation within oak-hickory upland forests have been documented throughout the Central Hardwoods Region. Previous studies suggest deviations from historic disturbance regimes may be a primary driver of vegetation change, necessitating the use of Fire Regime Condition Class (FRCC) guidelines to measure changes in forest structure. Current parameters of forest structure and fuel loading were assessed within mature oak-hickory uplands throughout the ecological subsections of the Shawnee National Forest, including the Greater Shawnee Hills, Lesser Shawnee Hills, Cretaceous Hills, and the Illinois Ozarks. Present species importance values and forest structure were compared with reference …

Characterization Of The Type Vi Secretion Systems Of P. Syringae Pathovars Phaseolicola And Syringae

Theses

Pseudomonas syringae is a bacterial plant pathogen that infects a large variety of agricultural crops. Bacteria colonize leaf surfaces and enter plant mesophyll tissue through wounds or stomata. Once inside, P. syringae can alter plant cell signaling pathways and suppress plant defense responses enabling it to grow in the intercellular space in the mesophyll. P. syringae possesses at least two types of virulence factors that suppress plant defense responses: i) small phytotoxin molecules, and ii) effector proteins that are translocated through specialized secretion systems. Gram-negative bacteria possess at least six types of secretion systems. The P. syringae type II and …

The Potential For Misleading Visual Communication On Food Packaging, Terry Ann Hayes

Theses

Consumers today are becoming more health conscious in light of America's growing obesity epidemic. Because of this, food companies often selectively highlight the healthfulness of their products, while carefully de-emphasizing the unhealthy components. These messages are frequently communicated by the food packaging itself, because packaging is a major influence on a shopper's perception of the food inside. The design of the food package, comprising both the two-dimensional surfaces and overall three-dimensional form, conveys these messages through variables related to color, imagery, typography, language, and shape. This thesis examined both organic and natural food packaging to uncover how healthfulness is communicated …

Moral Concerns In Genomic Medicine Beyond Gina, Stuart Paul Reeves

Theses

Genomic medicine, including pharmacogenomics, represents a potential paradigm shift in the diagnosis of disease and delivery of healthcare. Beyond the promise to address and resolve pandemics affecting specific ethnic/racial communities is the potential to develop pharmacological therapies custom tailored to the individual patient¿s genomic profile. However, the delivery of such promise rests on the contribution of genomic samples from individuals in communities where the culpable polymorphisms are present in high volumes. With the potential for an ever-widening disparity in overall population health among the socio-economic tiers in which these communities are often found, a theory of justice is needed to …

In Silico Drug Design Of Potential Novel Anti Malarial Agents, Vishal Thovarai

Theses

This thesis project incorporates the principles of rational and computer aided drug design in the quest for an improved anti-malarial agent. The target, a pathway for isoprenoid biosynthesis (the deoxy-D-xylulose-5-phosphate (DOXP) pathway) occurs in the parasite plastid – the apicoplast, and among the factors that make it an excellent target for an anti-malarial agent is its uniqueness from the pathway in the host, thus accounting for its specificity and low toxicity. A library of 18 potential anti malarial analogues/ ligands were designed and tested in silico against the receptor using molecular docking. The analogue L ο (omicron) - {3-[acetyl(hydroxy)amino]-1-hydroxypropyl} phosphonic …

Generating Sustainable Weight Loss: Investigating The Efficacy Of A Behavioral Based Weight Loss Intervention, Michael James Bordieri

Theses

Two thirds of Americans are overweight or obese. Traditional obesity interventions (e.g. drug therapy, diets, behavior therapy) generate moderate short-term weight loss but have little evidence of long-term weight maintenance. The cultural phenomenon of "yo-yo dieting" mirrors empirical findings which suggest that weight loss, albeit demanding, is a far easier process to target than weight maintenance. The present study sought to evaluate the efficacy of an acceptance based behavioral intervention designed to generate improvements in psychological health and quality of life in obese and overweight adults as well as encourage gradual and sustainable weight loss. The therapy package combined the …

Understanding The Link Between Ethanol Production And Food Prices, Nathalia Ferreira Monteiro

Theses

Food prices have increased rapidly in recent years, and so has ethanol consumption. Some studies have claimed that there is a connection between those two. Net exporters of food tend to benefit from higher prices, while regions that are net importers of food, tend to be adversely affected. The large amount of poor countries in the second group justifies an investigation of the causes of increasing food prices. This thesis aims to contribute to the discussion, analyzing, theoretically and empirically, the impact that the diversion of feedstock from food to ethanol production has on food prices. The interaction between food …

Epidemiology And Drug Resistant Profiles Of Candida Species, In Cork Hospitals., Emma Mccurtin

Theses

Candida causes superficial infections in healthy individuals; however in the immunocompromised host Candida can cause invasive, systemic infections and is a significant cause of morbidity and mortality. This is not due to a more virulent phenotype but to a weakened immune system unable to fight this opportunistic pathogen. The immunocompromised population is ever increasing, due to medical advancements and more aggressive treatments, and hence is the need for epidemiological data of these potentially life threatening infections. The aim of this study was to provide an epidemiological snapshot, of Candida infections from the immunocompromised population in Cork hospitals. Surveillance programmes from …

Gender Bias Of Cardiovascular Risk In Caucasian Type Ii Diabetics: A Haemostatic Explanation?, William Quirke

Theses

People with type II diabetes are disproportionately affected by cardiovascular disease compared to those without diabetes. The relative risk of cardiovascular disease caused by type II diabetes is higher in females than in males. This risk has not been fully explained by traditional risk factors and attention has turned to the possible role of haemostatic abnormalities in explaining the excess cardiovascular morbidity and mortality among diabetic females. We examined specific parameters of the coagulation (factor VII, factor VIII, von Willebrand factor, fibrinogen) and fibrinolytic (plasminogen activator inhibitor- 1, thrombin-activatable fibrinolysis inhibitor) system in 113 Irish Caucasian type II diabetics to …
