Arachidonic Acid Reverses The Pyriproxyfen And Ibuprofen Induced Toxicity In Daphnia Magna, Gautam Kumar Ginjupalli
Arachidonic Acid Reverses The Pyriproxyfen And Ibuprofen Induced Toxicity In Daphnia Magna, Gautam Kumar Ginjupalli
All Dissertations
Healthy reproduction and neonatal sex ratios of Daphnia are crucial to the health of the aquatic ecosystems in which Daphnia play principal roles in trophic transfer of nutrients. Combinations of environmental factors such as availability and quality of diet, overcrowding, hypoxia, reduced photoperiods and fall in ambient temperatures perturb normal parthenogeneic reproduction and induce sexual reproduction through male production. Male production provides a mechanism for overcoming specific stressors such as overcrowding and overwinter pond desiccation. However, it also induces a decrease in the Daphnia population that could have adverse implications on the pond ecosystem that depend on Daphnia . Interestingly, …
The Household Poverty Dimensions Infuencing Forest Dependence In Protected Area Neighboring Communities In Africa And The Mitigation Potential Of Tourism: The Case Of Volcanoes National Park, Rwanda, Ian Munanura
All Dissertations
Volcanoes National Park (VNP) in Rwanda is one of the important protected areas for conservation in the Albertine Rift ecoregion. It inhabits some of the most rare and endemic wildlife species including mountain gorillas. Despite such importance, it continues to be threatened by forest dependence practices of local residents such as, poaching for bush meat and the harvest of non-timber forest products. These practices have been attributed largely to high levels of poverty among park neighboring residents. It is believed that poor residents rely on forest resources to supplement their subsistence livelihoods. The relationship between poverty and forest dependence behavior …

Analyses Of Multivitamins In Nutraceuticals By Reverse Phase Hplc With Dad, Elsd And Ms, Hsiang-Chi Huang
All Theses
ABSTRACT
Vitamins are essential to human beings and support long-term healthy lifestyle. They exist widely in food, but in small amount. Hence, dietary supplements and fortified food products are more and more popular in the nutritional markets. According to the Infant Formula Act of 1980, the range of each of the nutrients should fall within a specific range or above the required minimum, so there is an increasing interest of accurate measurement of vitamins, particularly the B-group vitamins. However, traditional methods for vitamin B analyses are time-consuming and often in poor accuracy. As a result, rapid and reliable analytical methods …
Genetic And Environmental Determinants In The Evolution Of Alternative Mating Strategies In The Sailfin Molly, Poecilia Latipinna (Poeciliidae: Poecilia: Mollienesia), Elizabeth Lange
All Theses
Understanding the genetic and environmental factors responsible for differences in size, morphology and behavior can aid in determining how alternative male mating strategies evolve in natural populations. One important environmental factor is nutrition, as it underlies growth of both body size and morphological traits that are linked to alternative mating strategies in many animals. In sailfin mollies, Poecilia latipinna , male size is fixed at maturity, highly variable within populations and correlated with dorsal fin morphology and expression of alternative male mating behaviors. Large males with exaggerated dorsal fins use courtship behavior while small males with reduced dorsal fins use …

Development Of Hplc Methods For The Determination Of Water-Soluble Vitamins In Pharmaceuticals And Fortified Food Products, Hung Khiem Trang
All Theses
Though many HPLC methods have been developed and reported in literature for vitamin analysis for the past two decades, applying certain methods directly from literature more than often fails to reproduce the results reported due to many variables of liquid chromatography. This issue was targeted in this project through the examination of chromatographic behaviors of water-soluble vitamins in order to help the analysts better modify methods from literature or even develop new methods from scratch to fit their analytical need with the resources available (e.g., columns, detectors, etc.) in their lab.
The first part of the project investigated the chromatographic …

Biofabrication Of Scaffolds For Intervertebral Disc (Ivd) Tissue Regeneration, Benjamin Whatley
Biofabrication Of Scaffolds For Intervertebral Disc (Ivd) Tissue Regeneration, Benjamin Whatley
All Dissertations
The ultimate goal of tissue regeneration is to replace damaged or diseased tissue with a cell-based or biomaterial-based tissue that accurately mimics the functionality, biology, mechanics, and cellular and extracellular matrix (ECM) composition of the native tissue. Specifically, the ability to control the architecture of tissue engineered constructs plays a vital role in all of these issues as scaffold architecture has an affect on function, biomechanics, and cellular behavior. Many tissue engineered scaffolds focus on the ability to mimic natural tissue by simulating the ECM due to the fact that in each distinct tissue, the ECM serves as a structural …

Role Of Phosphoinositide-Based Signaling In Virulence In Entamoeba Histolytica, Amrita Koushik
Role Of Phosphoinositide-Based Signaling In Virulence In Entamoeba Histolytica, Amrita Koushik
All Dissertations
Entamoeba histolytica is an intestinal protozoan parasite and is the causative agent of amoebiasis. Upon entering the human host, cellular processes such as adhesion, phagocytosis, motility and secretion play a vital role in its propagation and pathogenicity. In other systems, each of these cellular processes is preceded by activation of signal transduction pathways, which often involve membrane phosphoinositides such as phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2). Little is known about phosphoinositide signaling in E. histolytica pathogenicity. In this study, we demonstrated that PI(4,5)P2 is localized to cholesterol-rich microdomains, lipid rafts, of the E. histolytica membrane and to the trailing edge …

All Dissertations
Escherichia coli O157:H7 and Listeria monocytogenes are pathogens that have received special attention by federal agencies, food safety researchers and food industries due to their economic and human health impact. To reduce the presence of these pathogens, alternative interventions have been studied. However, increasing consumer's demand for natural ingredients has made the investigations of effectiveness of natural antimicrobials necessary. In this study, in vitro antimicrobial activity of bromelain and papain against E. coli JM109 and L. monocytogenes was investigated. Furthermore, actinidin and papain were evaluated to reduce populations of L. monocytogenes strain and three mixed strains of E. coli O157:H7 …
Electrospun Nanofiber Yarns For Nanofluidic Applications, Chen-Chih Tsai
Electrospun Nanofiber Yarns For Nanofluidic Applications, Chen-Chih Tsai
All Dissertations
This dissertation is centered on the development and characterization of electrospun nanofiber probes. These probes are envisioned to act like sponges, drawing up fluids from microcapillaries, small organisms, and, ideally, from a single cell. Thus, the probe performance significantly depends on the materials ability to readily absorb liquids. Electrospun nanofibers gained much attention in recent decades, and have been applied in biomedical, textile, filtration, and military applications. However, most nanofibers are produced in the form of randomly deposited non-woven fiber mats. Recently, different electrospinning setups have been proposed to control alignment of electrospun nanofibers. However, reproducibility of the mechanical and …

Residential Summer Camp: A New Venue For Nutrition Education And Physical Activity Promotion, Alison K. Ventura, Barry A. Garst
Publications
Millions of children attend residential summer camps each year. However, few studies have examined the potential of camps for obesity prevention efforts. Research in the domain of positive youth development has shown that camp programs as short as one week have both short- and long-term positive effects on self-esteem, self-efficacy and other youth outcomes. The objective of the present study was to highlight the potential of resident camps as promising venues for the promotion of healthy eating and physical activity behaviors in the children who attend.

Evaluation Of Wetland Plants For Susceptibility To Species Of Phytophthora Present In Runoff Water At Ornamental Plant Nurseries, Garrett Ridge
All Theses
Competition between agricultural producers and urban communities for high quality water is increasing; therefore, growers need to adopt water conservation and reuse practices to ensure an adequate supply of irrigation water. One concern with recycled irrigation water is the potential to recirculate propagules of oomycete pathogens. Constructed wetlands are a biologically-based treatment option for nutrient and chemical remediation that potentially also could filter pathogen propagules. The goal of this study was to assess the susceptibility of plants routinely used in constructed wetlands to infection by species of Phytophthora commonly found at ornamental plant nurseries. In laboratory and greenhouse experiments, an …

Bacterial Recovery, Transfer To Hands And Survival On Restaurant Menus, Ibtehal Alsallaiy
All Theses
Some non-food contact surfaces such as restaurant menus are not routinely cleaned or evaluated for microbial contamination and thus may be a potential contamination risk. The main objectives of this study were to detect bacteria on restaurant menus, test the rate of bacteria transfer from menus to consumers and determine the survival rate of bacteria on the menu surface. Evaluation of samples can 'find' that menus harbored detectable levels of aerobic organisms and Staphylococcus spp. The average mean of Total Plate count (TPC) was 28 CFU/15cm2 per sampling area during busy periods and 15 CFU/15cm2 per sampling area during less …
The Effect Of Packaging Material Properties On Consumer Food Quality Perception In Quick-Service Restaurants, Emily Thackston
The Effect Of Packaging Material Properties On Consumer Food Quality Perception In Quick-Service Restaurants, Emily Thackston
All Theses
The majority of menu items available in quick-service restaurants (QSR) are consumed directly from a container or package. The main reasons consumers choose to eat fast food are because it is convenient, prepared quickly, a good value, and inexpensive. Therefore, the packaging becomes an integral part of the food product and from a consumer perspective must be consistent with their expectations and motives for choosing to eat fast food. Prior research has directly linked characteristics of consumer food packaging experience to their perception of its contents. The purpose of this research is to determine if consumer quality perception of food …
