Role Of "Caax" Protein Processing In The Retina, Jeffrey Rowan Christiansen Jan 2011

Role Of "Caax" Protein Processing In The Retina, Jeffrey Rowan Christiansen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Prenylation is a posttranslational modification which adds a lipid, either a farnesyl or geranylgeranyl group, to the C-terminal cysteine of proteins ending in a "CAAX" motif. Two additional steps referred to as "CAAX" protein processing follow prenylation. First, the terminal three amino acids are cleaved by the endoprotease RAS converting enzyme1 (RCE1), then isoprenylcysteine methyltransferase (ICMT) adds a methyl group to the cysteine. While it is clear that the addition of the prenyl group is required for the association of proteins with membranes, the function of proteolysis and methylation is not obvious. Two lines of evidence suggest a critical role …

Development Of High Volume Fly Ash And/ Or Slag Modified Concrete And Geopolymer Concrete As Sustainable Construction Materials, Soumya Sundar Chowdhury

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although cement constitutes only about 10% to 15% of the total weight of concrete, it accounts for 6% of global CO2 emissions. The other emissions from cement plants are: particulate matter, CO, NOx, SOx, total hydrocarbon, and the major wastes are cement kiln dust and water. Unfortunately cement is also an energy intensive material as 1 metric tonne of cement requires 1 million MJ of energy. Therefore, a large reduction in cement content in concrete by replacing it with other cementitious materials can make concrete a greener and sustainable material. Industrial by-products such as fly ash and ground granulated blast …

This is particularly evident in female rats due to their susceptibility to diet induced renal disease. In female rats, the initiation of chronic kidney disease …


Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell Jan 2011

Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lysine is thought to be oxidized primarily by lysine alpha-ketoglutarate reductase (LKR) and saccharopine dehydrogenase (SDH), which are restricted to the mitochondrial matrix. Lysine is presumably transported through the plasma membrane by isoforms(s) of a cationic amino acid transporter (CAT). Although the mechanism(s) of lysine transport through the inner mitochondrial membrane is not known, it is presumptively transported by one or both mitochondrial "ornithine transporters" (ORC-1/ORC-2). Tissue distribution of LKR and the mechanism(s) responsible for alterations in hepatic lysine catabolism in swine are unclear. Also, the roles of the alternative pathways of lysine degradation, the L-amino acid oxidase-dependent (LAAO), in …

Rapid Assessment Of Delay-Of-Reinforcement Effects On Key Pecking Maintained By Fixed-Ratio Schedules, David P. Jarmolowicz Jan 2011

Rapid Assessment Of Delay-Of-Reinforcement Effects On Key Pecking Maintained By Fixed-Ratio Schedules, David P. Jarmolowicz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research on delay of reinforcement has focused primarily on variable-interval schedules. A fair amount is known about effects of delay duration, signaled versus unsignaled delays, and interval length in the context of these schedules. Less is known about these effects on other schedules of reinforcement. For example, little is known about the effects of delay duration, signals versus unsignaled delays, or the way that delays interact with ratio requirement when behavior is maintained by fixed-ratio schedules. Furthermore, the steady-state designs (wherein stable responding is obtained at each delay duration) used to investigate delay-of-reinforcement effects are often time consuming. The …
