Single Step Synthesis Of Antibiotic Kanamycin Embedded Gold Nanoparticles For Efficient Antibacterial Activity, Shravan Gavva Aug 2013

Single Step Synthesis Of Antibiotic Kanamycin Embedded Gold Nanoparticles For Efficient Antibacterial Activity, Shravan Gavva

Masters Theses & Specialist Projects

Nanotechnology has become the most advanced type of drug delivery system within the last decade. This advancement shifted the focus on small carriers to increase the efficiency of the drugs. Among these, gold nanoparticles (GNPs) were found to have profound biomedical applications. In current research, kanamycin embedded GNPs were prepared in a single step, single phase, and bio-friendly (green synthesis) procedure. The synthesized Kanamycin-GNPs (Kan-GNPs) were spherical in shape and had a size range of 15 ± 3 nm. The chosen kanamycin is an aminoglycosidic antibiotic that is isolated from Streptomyces kanamyceticus. These special antibiotic GNPs are further characterized using …


Development Of Tools To Assess The Effects Of Lunasin On Normal Development And Tumor Progression In Drosophila Melanogaster, Gillian E. Jones Aug 2013

Development Of Tools To Assess The Effects Of Lunasin On Normal Development And Tumor Progression In Drosophila Melanogaster, Gillian E. Jones

Masters Theses & Specialist Projects

Soy contains many bioactive molecules known to elicit anti-cancer effects. One such peptide, Lunasin, has been shown to selectively act on newly transformed cells while having no cytotoxic effect on non-tumorigenic or established cancer cell lines. In this study we attempt to understand the developmental effects of Lunasin overexpression in vivo and create reagents that will help us understand Lunasin’s anti tumorigenic effects in an intact organism. cDNA encoding lunasin and EGFP-lunasin were cloned into pUAST and microinjected into Drosophila embryos. Tissue-specific overexpression of EGFP-Lun in the resulting transgenic lines was accomplished by crossing transgenics to various GAL4 driver lines. …


Effect Of Coconut Oil On Ulcerative Colitis In The Mouse Model, Pranav Chandra Alok May 2013

Effect Of Coconut Oil On Ulcerative Colitis In The Mouse Model, Pranav Chandra Alok

Masters Theses & Specialist Projects

Ulcerative colitis (UC) is a chronic disease of the colon or large intestine that causes inflammation and ulceration of the inner lining of the colon and rectum. In patients with ulcerative colitis, the body’s immune system overreacts and the body mistakes food, bacteria or other internal materials in the colon for an invading substance. The immune system attacks the material, thus irritating the colon. Limited knowledge of inflammatory conditions coupled with a narrow range of therapeutic options necessitates investigating the role of natural products. This study describes the effect of natural coconut oil on chemically-induced acute and chronic disease in …


Biomass Assisted Synthesis Of Antibacterial Gold Nanoparticles And Commentary On Its Future Potential And Applications In Medicine, Chad Willis May 2012

Biomass Assisted Synthesis Of Antibacterial Gold Nanoparticles And Commentary On Its Future Potential And Applications In Medicine, Chad Willis

Mahurin Honors College Capstone Experience/Thesis Projects

Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the green synthesis and characterization of biocompatible, biodegradable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potential antibacterial activity. GNPs were synthesized using the bioreduction property of xylose on the chloroaurate anions in an aqueous solution at room temperature and at atmospheric pressure. The characterization of synthesized GNPs was examined by UV-vis spectroscopy; transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR). Results indicate that the particles were stable; near spherical in shape with an …
