Suppression Of Chronically Induced Breast Carcinogenesis And Role Of Mesenchymal Stem-Like Cells, Kusum Rathore
Suppression Of Chronically Induced Breast Carcinogenesis And Role Of Mesenchymal Stem-Like Cells, Kusum Rathore
Doctoral Dissertations
Sporadic breast cancers are mainly attributable to long-term exposure to environmental factors, via a multi-year, multi-step, and multi-path process of tumorigenesis involving cumulative genetic and epigenetic alterations in the chronic carcinogenesis of breast cells from a non-cancerous stage to precancerous and cancerous stages. Epidemiologic and experimental studies have suggested that various dietary compounds like green tea and grape seed may be used as preventive agents for breast cancer control. In this research, I have developed a cellular model that mimics breast cell carcinogenesis chronically induced by cumulative exposures to low doses of environmental carcinogens. I used the chronic carcinogenesis model …
Examining The Roles Of Pstoc75 Potra Domains In Chloroplast Protein Import, Richard Franklin Simmerman
Examining The Roles Of Pstoc75 Potra Domains In Chloroplast Protein Import, Richard Franklin Simmerman
Masters Theses
During chloroplast formation via endosymbiosis most of the plastid genome was transferred to the host nuclear genome. Genomic and proteomic analysis suggests that >95% of the original plastid proteome is now encoded in the nucleus, and these now cytosolically fabricated proteins require a post-translational transport pathway back into the organelle. This process is not well understood, yet it has been shown to involve translocons at the outer and inner envelope of the chloroplast membranes (TOC & TIC). These translocons interact with a cleavable N-terminal extension of between 20 and 100 residues on chloroplast-bound precursor proteins known as the transit-peptide. Precursor …
A Time-And-Space Parallelized Algorithm For The Cable Equation, Chuan Li
A Time-And-Space Parallelized Algorithm For The Cable Equation, Chuan Li
Doctoral Dissertations
Electrical propagation in excitable tissue, such as nerve fibers and heart muscle, is described by a nonlinear diffusion-reaction parabolic partial differential equation for the transmembrane voltage $V(x,t)$, known as the cable equation. This equation involves a highly nonlinear source term, representing the total ionic current across the membrane, governed by a Hodgkin-Huxley type ionic model, and requires the solution of a system of ordinary differential equations. Thus, the model consists of a PDE (in 1-, 2- or 3-dimensions) coupled to a system of ODEs, and it is very expensive to solve, especially in 2 and 3 dimensions.

Protein Engineering For The Enhanced Photo-Production Of Hydrogen By Cyanobacterial Photosystem I, Ifeyinwa Jane Iwuchukwu
Protein Engineering For The Enhanced Photo-Production Of Hydrogen By Cyanobacterial Photosystem I, Ifeyinwa Jane Iwuchukwu
Doctoral Dissertations
Photosystem I (PSI) from plants, algae, and cyanobacteria can mediate H2 evolution in vivo and in vitro. A simple, self-platinization procedure that permits stable PSI-mediated H2 evolution in vitro has been developed. The H2 evolution capabilities of PSI from Thermosynechococcus elongatus have been characterized. This organism utilizes cytochrome c6 (cyt c6) as the e- donor to P700. Using a solution-based, self-organized platinization of the PSI nanoparticles, this study demonstrates a sodium ascorbate-cyt-PSI-Pt-H2 electron transport and proton reduction system that yields light-dependent H2. The system was thermostable with H2 evolution increasing up to 55°C. In addition, stability studies have shown the …
The Effects Of Bisphenol A On Adipose Tissue Development, Metabolism, And Endocrine Function And The Role It May Play In The Development Of Obesity, Brantley Nelson Wyatt
The Effects Of Bisphenol A On Adipose Tissue Development, Metabolism, And Endocrine Function And The Role It May Play In The Development Of Obesity, Brantley Nelson Wyatt
Masters Theses
While diet and sedentary lifestyle remain important factors in the development of obesity, recent findings have shown the possible involvement of environmental obesogens, chemicals that can disrupt homeostatic energy balance and increase adiposity. Bisphenol A (BPA) is a compound used in the manufacturing of plastics as a hardening agent and is ubiquitous in the environment due to its widespread use. BPA has been shown to be an endocrine disruptor through its ability to mimic estrogen, which is now known to play important roles in adipose tissue growth and metabolism. In fact, a small but compelling number of studies have shown …
