Human Collagen Krox Up-Regulates Type I Collagen Expression In Normal And Scleroderma Fibroblasts Through Interaction With Sp1 And Sp3 Transcription Factors., Magdalini Kypriotou, Gallic Beauchef, Christos Chadjichristos, Russell Widom, Emmanuelle Renard, Sergio A. Jimenez, Joseph Korn, François-Xavier Maquart, Thierry Oddos, Otto Von Stetten, Jean-Pierre Pujol, Philippe Galéra

Department of Medicine Faculty Papers

Despite several investigations, the transcriptional mechanisms that regulate the expression of both type I collagen genes (COL1A1 and COL1A2) in either physiological or pathological situations, such as scleroderma, are not completely known. We have investigated the role of hc-Krox transcription factor on type I collagen expression by human dermal fibroblasts. hc-Krox exerted a stimulating effect on type I collagen protein synthesis and enhanced the corresponding mRNA steady-state levels of COL1A1 and COL1A2 in foreskin fibroblasts (FF), adult normal fibroblasts (ANF), and scleroderma fibroblasts (SF). Forced hc-Krox expression was found to up-regulate COL1A1 transcription through a -112/-61-bp sequence in FF, ANF, …

The Use Of Non-Natural Nucleotides To Probe Template-Independent Dna Synthesis, Anthony J. Berdis, David Mccutcheon

Chemistry Faculty Publications

The vast majority of DNA polymerases use the complementary templating strand of DNA to guide each nucleotide incorporation. There are instances, however, in which polymerases can efficiently incorporate nucleotides in the absence of templating information. This process, known as translesion DNA synthesis, can alter the proper genetic code of an organism. To further elucidate the mechanism of template-independent DNA synthesis, we monitored the incorporation of various nucleotides at the “blunt-end” of duplex DNA by the high-fidelity bacteriophage T4 DNA polymerase. Although natural nucleotides are not incorporated at the blunt-end, a limited subset of non-natural indolyl analogues containing extensive π-electron surface …

Differential Response Of Various Spore Species To Sporicidal Disinfectants, Michael David Pratt

Theses and Dissertations

In the fall of 2001, letters laced with anthrax spores were delivered to various news organizations in New York and Florida, as well as to two Senators in Washington, D.C. Over 22 anthrax infections and five deaths resulted from exposure to these spores, and decontamination of the affected buildings was both time consuming and costly. Since these attacks, interest in sporicidal disinfectants has increased greatly. Many chemical sporicidal disinfectants are available commercially, but the exposure time required to sterilize can be relatively long. In addition, some spores are simply injured or inhibited by chemical disinfectants, but not necessarily killed. Studies …

Continuous Simulation Of Groundwater Use And Effluent Discharge In Catfish (Ictalurus Punctatus) Ponds At Five Locations In The Southeast U.S, Sugeng Triyono

Theses and Dissertations

Long-term climatological data were used to evaluate the effectiveness of a drop/add management strategy to reduce groundwater use and effluent discharge in catfish ponds in the southeast U.S.. A drop/add approach is based on the creation of a storage volume in the pond for rainfall collection. The storage volume is created by allowing water level in the pond to decrease until some minimum level is reached. When the minimum level is reached, the pond is partly refilled, leaving the remaining volume available to capture incident precipitation. In this way, the role of precipitation in the water budget is increased. In …

Free-Form Deformation For Computer-Aided Engineering Analysis And Design, Amy Lynn Ladner

Theses and Dissertations

Toward support of the use of geometry in advanced simulation, a freeorm deformation (FFD) tool was designed, developed, and tested using object oriented (OO) techniques. The motivation for creating this FFD tool in-house was to provide engineers and researchers a cost efficient, quick, and easy way to computationally manipulate models without having to start from scratch while readily seeing the resulting geometry. The FFD tool was built using the OO scripting language, Python, the OO GUI toolkit, Qt, and the graphics toolkit, OpenGL. The tool produced robust and intuitive results for two-dimensional shapes especially when multiple point manipulation was utilized. …

A Bioeconomic Model Of Recirculating Shrimp Production Systems, Xia Vivian Zhou

Theses and Dissertations

To prevent disease outbreaks and increase competitiveness of U.S. shrimp products, U.S. aquaculture researchers have developed super-intensive, bio-secure, recirculating shrimp production systems since the early 1990s. The general objective of this research is to determine an optimal production strategy to maximize the net revenue for the system. An inventory optimization model was built to determine the optimal harvesting week, shrimp size, and number of crops per year for experimental trials conducted at the Gulf Coast Research Laboratory (Ocean Springs, MS), the Waddell Maricultural Center (Bluffton, SC), and the Oceanic Institute (Oahu, HI). Survival rate and selling price sensitivity analyses were …

Assessment Of Uncertainty In Flow Model Parameters, Channel Hydraulic Properties, And Rainfall Data Of A Lumped Watershed Model, Jairo Nelvedir Diaz-Ramirez

The Role Of A Non-Microtubule-Based Spindle Matrix In Eukaryotic Cellular Division, Melissa Gwen Chambers

Theses and Dissertations

A non-microtubule-based spindle matrix has been observed in Drosophila melanogaster meiotic and somatic cells. This matrix comprises the proteins: Skeletor, Megator and Chromator, which localize to the nuclear periphery and chromosomes at prophase and to the microtubule spindle during mitosis and meiosis. This matrix might play a role in nuclear organization and microtubule assembly and stabilization. It is important to determine the presence or absence of this matrix in other species in order to compare form and function to that in Drosophila. These matrix proteins were studied in both normally dividing cells and cells in which division was disrupted. Our …

Economic Impacts Of White-Tailed Deer From Hunting In Mississippi, Micah Whittington Whiteside

Theses and Dissertations

White-tailed deer (Odocoileus virginianus) are an important ecological, social, and economic resource in Mississippi. Studies have been conducted on expenditures by white-tailed deer hunters, but none have administered a research-based, economic impact assessment for white-tailed deer in Mississippi. The economic impacts and associated values of white-tailed deer in Mississippi through a selfministered mail questionnaire were examined to collect white-tailed deer hunter expenditure data during the 2003/2004 hunting season. Expenditures of white-tailed deer hunters were obtained from a mail survey (N = 1,257, 38.6% response rate) and were used in an input-output model to determine economic impacts for the State. Economic …

Effects Of 6/85-Strain Mycoplasma Gallisepticum Inoculation Alone At 10 Weeks Of Age Or In Conjunction With Fmg Inoculation Overlays At 22 Or 45 Weeks Of Age On The Performance, Egg, Blood, And Visceral Characteristics Of Commercial Egg Laying Hens, Kristin Allo Viscione

Theses and Dissertations

The effects of 6/85-strain M. gallisepticum (6/85MG) inoculation alone or in conjunction with a F-strain M. gallisepticum (FMG) over-lay and its timing on the performance, egg, blood, and visceral characteristics of commercial egg laying hens were investigated. The applied treatments did not affect layer performance, but did affect yolk moisture and fatty acids, liver moisture, and plasma protein. The plasma protein and liver moisture changes may be indicative of the effects of the treatments on the hydration statuses of the birds during lay, whereas alterations in yolk palmitic, oleic, and linolenic acid levels with treatment may have been manifested by …

Nmr Structure And Relaxation Studies Of Dhfr From Haloferax Volcanii At High Salt, Bulent Binbuga

Theses and Dissertations

The studies of enzymes from extreme sources have gained significance due to their increasing potential applications. The proteins from halophiles (salt loving) have adapted to challenging environmental conditions and require salt for their structure and function. How halophilic proteins adapt to a hypersaline environment is still an intriguing question. It is important to mimic the environmental conditions of the sample under investigation with experimental techniques. In this study, structure and dynamic features of a halophilic enzyme have been investigated under high salt conditions. The acquisition of NMR data on high salt samples has always been problematic. We have devised a …

Proteome And Phosphoproteome Dynamic Change During Cell Dedifferentiation In Arabidopsis Thaliana, Brahmananda Reddy Chitteti

Theses and Dissertations

Cell dedifferentiation is a cell fate switching process in which a differentiated cell reverts to a status with competence for cell division and organ regeneration like an embryonic stem cell. Although the phenomenon of cell dedifferentiation has been known for over two and a half centuries in plants, little is known of the underlying mechanisms. Here, the proteome map of Arabidopsis cotyledons has been established and investigated the dynamic change of the cotyledon proteome in the time course of cell dedifferentiation. Among the 353 distinct genes, corresponding to 500 2-DE gel protein spots identified with high confidence, 12% have over …

Influence Of Nursery Stock, Planting Practices, Fertilization And Competition Control On Initial Survival And Growth Of Nuttall And White Oak Seedlings, Joshua Larue Moree

Theses and Dissertations

This project evaluates the survival and initial growth response of oak seedlings produced under special nursery protocols (?enhanced? seedlings) compared to nursery-run oak seedlings of the same species, and the influence of various cultural practices on these same nursery stocks. Survival did not differ significantly between nursery stocks. Significant differences in survival among competition control treatments did occur. Intensive competition control regimes using glyphosate can negatively impact seedling survival if seedlings come in contact with herbicide spray drift.Nursery-run seedlings had significantly greater growth and many were larger than enhanced seedlings after two growing seasons. Height growth was typically greater with …

Systematics Of Holarctic Teleiodini (Lepidoptera : Gelechiidae), Sangmi Lee

Theses and Dissertations

Phylogenetic relationships of 25 genera of Holarctic Teleiodini (Gelechiidae) are postulated based on morphology and molecular characters, including CO?I, CO?II, and 28S genes. The phylogenetic analysis of the morphology matrix yielded six equal most parsimonious trees (length 329 steps, CI = 0.38, RI = 0.53) and a strict consensus tree (length 342 steps, CI = 0.36, RI = 0.50) with two polytomies and two trichotomies. The phylogenetic analysis of the combined morphology matrix and the CO?I + CO?II + 28S matrix yielded two equally most parsimonious trees (length 1184 steps, CI = 0.50, RI = 0.41) and a strict consensus …

The Ecology And Morphological Variation Of Opuntia (Cactaceae) Species In The Mid-South, United States, Lucas C. Majure

Theses and Dissertations

Opuntia species have been poorly studied ecologically and taxonomically in the eastern United States. This study deals with the ecology of Opuntia species in the mid-south United States and covers not only the high degree of morphological variation exhibited by taxa, but also the taxonomy and distributions of the group for Mississippi. The taxa in the mid-south have distinct habitat preferences and can be separated based on habitat characterization. Information from this work provides valuable data useful in predicting possible routes that an invasive species, Cactoblastis cactorum (the cactus moth), might use in its potential westward migration. Phenotypic plasticity exhibited …

The Effects Of Changing Technology On Average Costs For Mississippi Cotton Producers: From 1996 - 2005, William Michael Thompson Ii

Theses and Dissertations

Row crop production can be characterized by constant change. Agricultural technology is responsible for most of the changes in productivity observed at the field level since the advent of mechanized farm equipment. Genetically modified (GM) cotton varieties have changed many aspects of cotton production in the United States. The advent of GM varieties has been the source of altered cropping practices in cotton production. The rapid adoption of GM cotton varieties in Mississippi has allowed producers to alter certain aspects of their farming operation because of added flexibility, increased yields, and other benefits of GM varieties. This study analyses the …

The Effects Of The Secondary Carbon Source Glycerol On The Lipid Accumulation And Fatty Acid Profile Of Rhodotorula Glutinis, Emily Ruth Echols Easterling

Theses and Dissertations

Producing biodiesel from triacylglycerol (TAG) generates glycerol as a byproduct which could be recycled and used to grow the oleaginous yeast Rhodotorula glutinis. R. glutinis has the ability to produce up to 70% of its weight in the form of TAG. This study is designed to determine the effects of glycerol on the TAG and fatty acids produced by R. glutinis.

The Influence Of Probiotic Lactobacilli On Glucose Uptake By Caco-2 Cells, Arun Kumar Rooj

Theses and Dissertations

The resident microbes of human gastrointestinal tract cause both harmful and beneficial effects and these effects can be modulated by the administration of beneficial probiotic bacteria. Probiotics attribute several therapeutic and preventive beneficial effects, for both humans and animals. Despite the good effects of probiotic bacteria, the role of probiotic bacteria or their metabolites on the nutrient uptake by enterocytes is very less known. Most studies describe the genomic effects of probiotic bacteria on the transport properties. This thesis describes the short term (10 min or less) non-genomic effects of probiotic bacteria on the glucose uptake by human enterocytes like …

The Metaphase Checkpoint In Cells Undergoing Mitosis Without Chromosome Duplication, Mary Kathrine Johnson

Theses and Dissertations

Chinese hamster ovary cells (CHO) were arrested with hydoxyurea at the beginning of DNA synthesis. Subsequent treatment with caffeine induced cells to bypass S-phase and undergo mitosis with unreplicated genomes (MUG). Treated cells built a normal spindle and distributed unattached kinetochores to daughter cells. To determine if MUG cells obey the metaphase checkpoint, we used immunoflourescence to detect and localize known metaphase checkpoint and motor proteins. In addition, the drug taxol was used to stabilize microtubules in MUG cells. The localization of CENP- E, the presence of anaphase A, taxol arrest, and taxol release acted in a similar manner as …
