The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Effect of pharmaceuticals and natural products on multidrug resistance mediatedtransport in Caco-2 and MDCKII-MDR1 drug transport models

Creator:: Fan, Ying
Abstract:: This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:: Konrad, Kevin
Abstract:: Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

The effect of food processing on the bioavailability of selenium in tuna and wheat : human and rat studies

Creator:: Alexander, Anne Rose
Abstract:: Bioavailability of selenium (Se) in processed tuna and wheat products was studied in humans and rats. The protein source of the rat diets was torula yeast with Se supplied by either raw, precooked or canned tuna, or whole wheat flour, bread or bran. Sodium selenite was used as a control....

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...
