Chemical And Genetic Composition Analysis Of Organic And Nonorganic Tortilla Chips, Aubrey White-Day
Chemical And Genetic Composition Analysis Of Organic And Nonorganic Tortilla Chips, Aubrey White-Day
Honors Theses
The aim of this study was to explore the chemical and genetic differences between organic and nonorganic tortilla chips using GC-MS and PCR. Twenty chip brands were selected: 10 organic and 10 nonorganic. A survey on shopping preferences was created and distributed to compare results of public opinion to experimental data. It yielded 212 responses. All organic chip brands, and one out of ten nonorganic chip brands, tested negative for GMOs. This study concluded that there are minimal chemical differences based on Jaccard similarity indicies and stark genetic differences between organic and nonorganic tortilla chips. In comparing statistical analyses to …
Effects Of Creatine, Leucine, And Ethanol On Glial Cell Line-Derived Neurotrophic Factor In C2c12 Skeletal Muscle Cells, Daniel Waters
Effects Of Creatine, Leucine, And Ethanol On Glial Cell Line-Derived Neurotrophic Factor In C2c12 Skeletal Muscle Cells, Daniel Waters
Honors Theses
Glial Cell Line-Derived Neurotrophic Factor (GDNF) is a protein expressed throughout the mammalian nervous system that serves several protective functions. Originally discovered in the brain, where it supports the survival of dopaminergic neurons, GDNF has since been shown to be expressed in skeletal muscle and is vital for the maintenance of motor neurons. The relationship between muscle hypertrophy, and GDNF is not well understood. The purpose of this study was to examine the relationship between hypertrophy and GDNF by inducing hypertrophy in C2C12 skeletal muscle cells using leucine and creatine, inhibiting hypertrophy using ethanol and measuring GDNF content. As measured …
Sds Non-Acrylamide Polymeric Gel-Filled Capillary Electrophoresis For Molecular Size Separation Of Protein, Devon Andres
Sds Non-Acrylamide Polymeric Gel-Filled Capillary Electrophoresis For Molecular Size Separation Of Protein, Devon Andres
Honors Theses
Sodium dodecyl sulfide (SDS) non-acrylamide gel-filled capillary columns are a new technology being used for analysis and separation of biotechnology-derived proteins. This research was to compare this new technology to the current methods of SDS polyacrylamide gel electrophoresis (SDS-PAGE) and high-performance size-exclusion chromatography (HPSEC). The molecular mass of four different recombinant proteins were determined by two commercialized SDS non-acrylamide gel-filled capillary columns, SDS-PAGE, and HPSEC. The data obtained showed that the SDS non-acrylamide gel-filled capillary columns were compatible with the SDS-PAGE technique for molecular mass determination. HPSEC was shown to be unreliable for molecular weight determination. SDS non-acrylamide gel-filled capillary …
