Baseline Survey And Habitat Analysis Of Aquatic Salamanders In The Pigeon River, North Carolina, Nikki J. Maxwell
Baseline Survey And Habitat Analysis Of Aquatic Salamanders In The Pigeon River, North Carolina, Nikki J. Maxwell
Masters Theses
The Pigeon River was severely impacted beginning in the early 1900s by a paper mill located in Canton, North Carolina. The mill discharged chemical byproducts into the Pigeon River until 1992 when the paper mill modified their processes. As a result, water quality improved but the status of salamander species in the Pigeon River was unknown. Worldwide amphibian declines over the last 20 years have drawn attention to the need for more research and a better understanding of species-specific habitat relationships. There is concern about amphibian population declines because amphibians are critical to the balance of ecosystems and are considered …
Morphological Convergence And Character Displacement In Two Species Of Polymorphic Salamanders (Genus Plethodon) In Eastern Tennessee, Jason R. Jones
Morphological Convergence And Character Displacement In Two Species Of Polymorphic Salamanders (Genus Plethodon) In Eastern Tennessee, Jason R. Jones
Masters Theses
In situations involving the co-occurrence ecologically similar species, one of two different evolutionary responses is often expected. If sympatry results in competition over a shared resource, character displacement would be a favored outcome, while morphological convergence is an alternative outcome if the species have similar responses to the shared environment. In this study, I examine cranial morphology and dorsal coloration of two ecologically similar salamander species (Plethodon serratus, the Southern Red-backed Salamander, and P. ventralis, the Southern Zig-zag Salamander) to evaluate the alternative hypotheses of character displacement or convergence. Results from linear morphometrics analyses showed no significant …
Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Masters Theses
Sedimentation affects both stream physical and biological integrity. Improperly designed stream passage accompanied with sedimentation and altered hydrology can impede fish passage and reduce fish assemblage integrity. The purpose of this study was to: 1) quantify impacts of poorly constructed road stream crossings and eroding banks on fish assemblages, and 2) assess these sites as sediment sources and connectivity breaks on entire fish assemblages and individual fish species. Electrofishing was conducted during spring and fall 2004 and 2005. A total of 29 electrofishing reaches were sampled which included 5 road-stream and streambank restoration sites. Sickle Creek (1st order) had reduced …
A Community Ecology And Stable Isotope Study Of Plankton, Macroinvertebrate, And Fish Communities Surrounding Groundwater Vents In Lake Huron, Michigan, Thomas Garrison Sanders Jr.
A Community Ecology And Stable Isotope Study Of Plankton, Macroinvertebrate, And Fish Communities Surrounding Groundwater Vents In Lake Huron, Michigan, Thomas Garrison Sanders Jr.
Masters Theses
Extreme environments can create ecotones with uncharacteristic physicochemical conditions and ecological communities. Recently, several submerged sinkholes were discovered in Lake Huron where hypoxic groundwater that is rich with dissolved ions intrudes into surrounding lake water. Researchers have documented large growths of cyanobacteria and chemosynthetic bacteria surrounding these groundwater vents, but little is known if this production is utilized by upper trophic level organisms and how the environmental conditions affect local community density and diversity. My objectives were threefold: (1) I wanted to confirm the presence and describe the nature and extent of chemical and physical gradients in the sublacustrine sinkhole …
From In-Vitro To In-Vivo: Corporate Development And Efficacy Of A Topical Hair Growth Agent Derived From Natural Extracts, Kelly Michael Glynn
From In-Vitro To In-Vivo: Corporate Development And Efficacy Of A Topical Hair Growth Agent Derived From Natural Extracts, Kelly Michael Glynn
Masters Theses
Androgenetic alopecia (male pattern baldness) affects up to 50% of the world’s population, propelling the development for a possible treatment. The hair follicle is influenced by several genetic and physiologic factors, which, when gone awry, lead to androgenetic alopecia. Vascular endothelial and keratinocyte growth factors are believed to be promoters of hair growth, as is inhibition of the proteasome complex. The cytokine IL-1α is also known to regulate follicle dynamics. The research objective described herein was an attempt to develop a botanical blend, which could mediate the above biomarkers, be successfully incorporated into a safe topical product and be evaluated …

Oxidative Stress, Calcium Homeostasis, And Altered Gene Expression In Human Lung Epithelial Cells Exposed To Zno Nanoparticles, Chuan-Chin Huang
Oxidative Stress, Calcium Homeostasis, And Altered Gene Expression In Human Lung Epithelial Cells Exposed To Zno Nanoparticles, Chuan-Chin Huang
Masters Theses
"The influence of 20 nm ZnO nanoparticles on oxidative stress, intracellular calcium homeostasis, and gene expression was studied in human bronchial epithelial cells (BEAS-2B). ZnO caused a concentration- and time-dependent cytotoxicity while elevating oxidative stress and causing membrane damage (cellular LDH release). There was a remarkably steep relationship between concentration and toxicity at concentrations from 5 to 10 μg/ml. Exposure to ZnO increased intracellular calcium levels in a concentration- and time-dependent manner. Treatment with the antioxidant N-acetylcysteine prevented cell loss and diminished the increase in intracellular calcium concentration, suggesting oxidative stress mediated cytotoxicity. Exposure to a sublethal concentration of ZnO …

In Vitro Evaluation Of Bioactive Glass Scaffolds And Modified Bioactive Glasses With An Osteogenic Cell Line, Vernon C. Modglin
In Vitro Evaluation Of Bioactive Glass Scaffolds And Modified Bioactive Glasses With An Osteogenic Cell Line, Vernon C. Modglin
Masters Theses
"This investigation consisted of two parts focused on bioactive glasses and scaffolds for in vitro growth of bone cells for tissue engineering and bone repair. The first part involved evaluation of the ability of two new types of porous 13-93 bioactive glass scaffolds to support the growth and differentiation of mouse MLO-AS cells, an established osteogenic cell line used as a model of developing bone tissue. The two scaffold types tested included 13-93 glass fiber and trabecular-like scaffolds seeded with MLO-AS cells and cultured for intervals of 2 to 12 days. Collectively, in vitro results indicate that the 13-93 glass …

Electricity Generation And Ethanol Production Using Iron-Reducing, Haloalkaliphilic Bacteria, Varun Paul
Masters Theses
"Microbial life in extreme environments has been studied primarily for their metabolic activities. Very few commercial or industrial applications have been known from these systems. In this study, the metabolic pathways and properties of bacteria from a haloalkaliphilic environment of Soap Lake, Washington were employed in two research applications related to energy production. In the first study, the bacterial cultures that were known to reduce iron (III) were used in a Microbial Fuel Cell (MFC) reactor. Iron reducing bacteria have shown to shunt their electrons on to the surface of a carbon electrode of an MFC, and the electrons can …
Nona-Arginine Peptides Facilitate Cellular Entry Of Semiconductor Nanocrystals: Mechanisms Of Uptake, Yi Xu
Nona-Arginine Peptides Facilitate Cellular Entry Of Semiconductor Nanocrystals: Mechanisms Of Uptake, Yi Xu
Masters Theses
"Luminescent semiconductor quantum dots (QDs) have recently been used for delivering and monitoring biomolecules, such as drugs and proteins. However, QDs alone have a very low efficiency of transport across the plasma membrane. In order to increase the efficiency of QD delivery, synthetic nona-arginine (sR9) was used, a cell penetrating peptide, to facilitate uptake. Data demonstrated that sR9 could significantly increase the cellular uptake of QDs by noncovalent binding between QDs and sR9. Furthermore, the mechanisms of QD/sR9 cellular internalization were investigated. Low temperature and metabolic inhibitors markedly inhibited the uptake of QD/sR9, indicating that internalization is an energy-dependent process. …
