Gold Nanoparticle Interactions And Impact Upon A Common Biofilm Source: Legionella Pneumophila , Amber Stojak Dec 2009

Gold Nanoparticle Interactions And Impact Upon A Common Biofilm Source: Legionella Pneumophila , Amber Stojak

All Theses

There exists widespread concern of pathogenic bacteria colonizing and establishing biofilms in water systems providing a direct exposure route to the public. Legionella are widely distributed in human-made and natural environments, and colonization lends the potential to infect human hosts that may lead to the development of Legionnaire's Disease. Silver has been used in cooling towers and water filtration systems for removal of planktonic bacteria and biofilms; however permanent removal of L. pneumophila biofilms with metal ions is impossible when established biofilms are in hard to access places such as dead end piping or inside a protozoan host. Bulk metals …

Molecular Analysis Of Split Hand/Foot Malformation (Shfm) At The Shfm3 And Shfm5 Loci, Megan Chryst-Ladd

All Theses

Split hand/foot malformation (SHFM) is a congenital limb malformation observed in humans characterized by a reduction or loss of the central digits of the hands and/or feet. The condition affects one in every 8,500 to 25,000 births, accounting for 8-17% of all limb reduction defects. A tandem duplication of approximately 500 Kb has been determined to be the causative mutation at the SHFM3 locus. Patients that are heterozygous for this duplication have three copies of the genes BTRC, POLL, and DPCD as well as an extra copy of exons 6-9 of FBXW4. The SHFM3 critical region also contains the FGF8 …

Inhibition Of Pi 3-Kinase Signaling Contributes To Metronidazole Resistance In The Protozoan Parasite, Entamoeba Histolytica, Rhonda Powell Dec 2009

Inhibition Of Pi 3-Kinase Signaling Contributes To Metronidazole Resistance In The Protozoan Parasite, Entamoeba Histolytica, Rhonda Powell

All Theses

Amoebiasis is defined as an intestinal infection with the human protozoan parasite, Entamoeba histolytica; approximately 100,000 deaths annually can be attributed to amoebiasis. Disease states range from asymptomatic colonization to invasive amoebiasis, characterized by abdominal pain and dysentery. Dissemination to extraintestinal sites, such as the liver and/or brain, can occur. Vesicle trafficking is critical for parasite virulence, and multiple signaling cascades within the pathogen facilitate these events.
One important regulator of signal transduction is the tightly controlled PI 3-kinase (PI3K), which phosphorylates the lipid, phosphatidylinositol bisphosphate (PIP2), producing phosphatidylinositol trisphosphate (PIP3). Effector proteins, such as Akt, …


Cloning And Expression Of Porcine Dicer And Argonaute-2, Heather Stowe Dec 2009

Cloning And Expression Of Porcine Dicer And Argonaute-2, Heather Stowe

All Theses

In vitro-produced embryos exhibit aberrations in development, but the reasons for these developmental problems are unknown. Recently, a class of small non-coding RNA called microRNA (miRNA) has been described and reported to have roles in normal mammalian embryonic development. These miRNAs are encoded in the genome, transcribed by RNA pol II and processed into fragments approximately 22 nt in length by ribonuclease enzymes, the final one being a protein called Dicer. miRNA work through the RNA-induced silencing complex (RISC), of which the argonaute gene family are key proteins. Argonaute-2 (Ago2) has been identified as the only member possessing endonuclease activity, …

Using A Multimedia Assessment Tool To Impact Evolution Education Strategies In South Carolina's Public High Schools, Matthew Johnson Dec 2009

Using A Multimedia Assessment Tool To Impact Evolution Education Strategies In South Carolina's Public High Schools, Matthew Johnson

All Theses

The theory of evolution is widely accepted as one of the fundamental disciplines of modern science. Evolution provides a foundation for all aspects of biology, and thus it is essential that present and future biologists have a detailed understanding of evolutionary principles. However, since the famous Scopes trial in 1925, the teaching of evolutionary theory in the public school system has been under attack. Though several court cases over the last 85 years have continually supported evolution and discredited creationism (the idea that evolution cannot explain the diversity of life on earth and therefore must have arisen through the influence …


Low-Dose Of Sodium Arsenite Causes Delayed Differentiation In C2c12 Mouse Myoblast Cells Through The Repression Of The Transcription Factor Myogenin, Amanda Steffens Dec 2009

Low-Dose Of Sodium Arsenite Causes Delayed Differentiation In C2c12 Mouse Myoblast Cells Through The Repression Of The Transcription Factor Myogenin, Amanda Steffens

All Theses

A number of epidemiological studies have correlated arsenic exposurwith cancer, skin diseases, cardiovascular diseases, and adverse developmental outcomes such as stillbirths, spontaneous abortions, neonatal mortality, low birth weight, and delays in the use of musculature. The current study used C2C12 mouse myoblast cells to examine whether low concentrations of arsenic could alter their differentiation into myotubes, which would indicate that arsenic has the ability to act as a developmental toxicant. Myoblast cells were exposed to 20nM sodium arsenite and allowed to differentiate into myotubes and expression of the muscle-specific transcription factor myogenin, along with the expression of myosin light chain …


Effects Of Vegetation Structure On Fire Behavior And Wiregrass Seedling Establishment In Xeric Sandhills, Evelyn Wenk Aug 2009

Effects Of Vegetation Structure On Fire Behavior And Wiregrass Seedling Establishment In Xeric Sandhills, Evelyn Wenk

All Theses

The xeric sandhills on Carolina Sandhills National Wildlife Refuge have a monospecific overstory of longleaf pine and an understory dominated by turkey oak and wiregrass. The understory vegetation is spatially heterogeneous within stands, with small patches dominated by either turkey oak or wiregrass, or lacking understory vegetation. I described the fuel complexes created by the variable vegetation structure, in terms of their chemical and physical properties, and used prescribed fire to test for differences in fire behavior among the vegetation types. In addition, I compared the effects of the vegetation structure and below-ground competition on the establishment of wiregrass.

Nudibranchs Of The Ross Sea, Antarctica: Phylogeny, Diversity, And Divergence, Christopher Shields Aug 2009

Nudibranchs Of The Ross Sea, Antarctica: Phylogeny, Diversity, And Divergence, Christopher Shields

All Theses

The Southern Ocean (SO) surrounding Antarctica is extremely cold and geographically isolated. The phylogenetic affinities of only a few SO taxa have been examined in detail; in these, a high degree of endemism and radiation within the SO has been established using molecular phylogenetic methods. In order to address these Antarctic paradigms, we used Bayesian inference to construct phylogenetic trees of nudibranch molluscs based on mitochondrial cytochrome-c oxidase I (COI) and 18S ribosomal DNA. We gathered sequences from temperate (COI n=37; 18S n=31) and polar (COI n=21; 18S n=22) species and then combined them with sequences retrieved from GenBank (COI …

Reproductive Strategies And Colony Relatedness In The Invasive Ponerine Ant Pachycondyla Chinensis (Emery), Andrew Tebeau

All Theses

Pachycondyla chinensis (Emery) (Formicidae: Ponerinae), is an ancestral ant introduced from Asia. It is considered a pest species of medical and ecological concern. Since its initial 1932 documentation occurring in three Southeastern U.S. states at relatively low frequencies, the invasion of P. chinensis has spread to at least three additional states in discontinuously widespread populations that are locally abundant. Little is known about P. chinensis population structure and reproduction, and an investigation into these strategies offers insight into the means by which this pest species proliferates, and ultimately, can assist in the design of management strategies. The objectives of this …


Development And Testing Of A Machine-Coatable Chitosan Coating Applied To A Flexible Packaging Sealant, Steffen Rau Aug 2009

Development And Testing Of A Machine-Coatable Chitosan Coating Applied To A Flexible Packaging Sealant, Steffen Rau

All Theses

Chitosan is a naturally derived material that has anti-microbial properties. Studies have shown that chitosan is effective when it is in contact with the surface of the product upon which the antimicrobial effect is desired. This suggests that chitosan should be on the inside surface of the package. In this work, a machine coatable chitosan coating was developed for application to the sealable (LDPE) side of a PET/LDPE lamination. The viscosities and percent solids of the coating were evaluated over 12 days. The coating was tested using manual drawdowns (Mayer rods) and also on a gravure coating line. Adhesion properties …

Anticancer Properties Of Research-Grade Hydrastis Canadensis (Goldenseal) And Characterization Of Its Effect On The Mdr1-Encoded Phosphoglycoprotein Efflux Pump, Sara Garrett

All Theses

Multiple drug resistance (MDR) in tumors, observed both in vivo and in vitro, is generally attributed to efflux-mediated reduced drug accumulation via mdr1/P-gp. Notoriously chemoresistant colorectal cancers exhibit the highest P-gp expression, account for 9% of all cancer deaths, and are the third most common cancer in men and women. P-gp, a 170kDa protein, contains twelve transmembrane segments with two ATP-binding domains used to extrude intracellular compounds of broad specificity against a concentration gradient. Studies concerning natural health products are becoming more prevalent in the search for safe anti-P-gp remedies and Hydrastis canadensis (goldenseal) was studied for its anti-cancer properties. …

Overseeded Bermudagrass Spring Trasition Response To Mowing Height, Nitrogen Rate, Sulfonylurea Herbicide, And Allelopathy, Raymond Mccauley

All Theses

Hybrid bermudagrass [Cynodon transvaalensis Burtt-Davey x C. dactylon (L.)
Pers.] is the preferred turf for golf courses and athletic fields across the southern United
States because of its dark green color, fine texture, good wear and drought tolerance, and
excellent recuperative rate. Despite its many attributes, bermudagrass goes dormant and
turns an unsightly brown color when soil temperatures fall below 10-13oC (50-55super>oF).
Perennial ryegrass (Lolium perenne L.) is often overseeded into bermudagrass in the fall
to sustain acceptable turf quality through the spring months. However, perennial ryegrass
aggressively competes with the bermudagrass for resources in the spring and potentially …

Managing Linepithema Humile (Mayr), The Argentine Ant, In South Carolina State Park Campgrounds, Brittany Ellis

All Theses

Linepithema humile (Mayr), the Argentine ant, is known as a pest in many urban areas of the southeastern United States. In the Piedmont region of South Carolina, there is a documented problem with L. humile invading the campsites of state park campgrounds. While some parks have tried to implement proactive control programs, the most widely used tactic is spraying insecticides when L. humile populations become intolerable to visitors. Although park personnel are treating problem areas with liquid insecticide, park visitors also treat their campsites with insecticidal products, as well as products not labeled for ant control.
Surveys in 2008 showed …

Root-Zone Characteristics And Bermudagrass Response To Saline Water Delivered By Subsurface Drip Irrigation, Kelsey Gorman

All Theses

Population growth and recurring drought conditions have placed high demands on freshwater resources in South Carolina. Thus, turfgrass irrigation management practices that reduce freshwater use while maintaining quality turfgrass need to be identified.
Previous research in the arid Southwest USA documents water conservation on bermudagrass by using saline water sources and subsurface drip irrigation (SDI) systems. A field-scale facility was constructed in Florence, SC, to evaluate `Tifway' bermudagrass
(Cynodon dactylon (L.) Pers. X C. transvaalensis Burtt Davy) quality, growth, and rootzone characteristics when subjected to saline (3.15 dS m-1) or freshwater (0.07 dS m-1) irrigation, SDI lines spaced 41 or …


Population Reconstruction Model To Analyze Harvest And Banding Data For Mourning Doves In South Carolina, Christopher Chumbley May 2009

Population Reconstruction Model To Analyze Harvest And Banding Data For Mourning Doves In South Carolina, Christopher Chumbley

All Theses

Mourning dove (Zenaida macroura) call count indices for South Carolina indicate a negative trend over the past 42 years (1.2% decline per year, p < 0.05). Total harvest estimates in the state increased from 2003-2007. Banding data from doves banded in South Carolina and data from annual examinations of harvested mourning dove wings during 2003-2007 were collected and analyzed. Data sets used contained 6,600 banded doves and 21,240 harvested dove wings. Survival estimates from band recovery analyses for adult and juvenile doves were 0.44 (± 0.04 SE) and 0.35 (± 0.06 SE), respectively. Survival rates were constant from year to year while recovery rates differed annually for adults and juveniles. The average natural mortality estimates for adults and juveniles in the presence of hunting were 0.45 ± 0.122 and 0.47 ± 0.189, respectively, during the study period. The average harvest and kill rates for adults and juveniles were also estimated. Age-at-harvest ratios adapted from annual wing examinations during the harvest were used with recovery rates to derive estimates of annual productivity in the population. Linear regression analysis of productivity estimates found a significant decline in productivity during 2003-2007 (-0.21, p < 0.10). The average productivity estimate was 1.43 (± 0.33 SE) juveniles per adult and the estimated productivity required to maintain a stable population was 1.60 (± 0.30 SE). The effects of constant survival rates, varying hunting mortality estimates and declining productivity estimates were discussed in relation to breeding populations in rural areas of South Carolina.
