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...

Biosynthesis, production and structural studies of secondary metabolites in cultured marine cyanobacteria

Creator:: Vulpanovici, Florina Alexandra
Abstract:: This thesis details investigations of marine cyanobacterial secondary metabolism, with emphasis on a strain of Phormidium sp. collected in Indonesia. These studies assessed the effects of nineteen putative elicitor compounds on the growth and metabolite production of five species of marine cyanobacteria, biosynthetic investigation of an intriguing secondary metabolite, phormidolide,...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

Crystallin proteolysis in lens during aging and cataract formation

Creator:: Ueda, Yoji
Abstract:: The major purpose of this research was to characterize partially degraded proteins appearing in the ocular lens during aging and cataract, and to identify the responsible proteolytic activities. This research is significant, because increased protein degradation is associated with lens opacification and cataract. Determining the sites where lens proteins become...

Micro total analysis system for in-situ and autonomous spectrophotometric monitoring of iron in groundwater

Creator:: Koch, Corey R.
Abstract:: We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...

Half-life : essays

Creator:: Fath, Lauren
Abstract:: Lauren Fath, in her non-fiction collection Half-Life: Essays, examines the underpinnings of her upbringing in suburban Fort Wayne, Indiana, focusing primarily on familial relationships and the importance of hindsight in understanding how our families make an imprint on our lives. By looking at our relationships through the lens offered by...

Network coding in relay networks

Creator:: Alban, Eduardo
Abstract:: Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...

Indole-3-carbinol and 3,3'-diindolylmethane : relative potency as modulators of drug metabolism and carcinogenesis

Creator:: Katchamart, Sirinmas
Abstract:: Indole-3-carbinol (I3C), the most abundant metabolite of glucobrassicins, is found in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage and cauliflower. I3C has been shown to have anticarcinogenic activity against many chemical carcinogens in multiple target organs in animal models. However, the anticarcinogenic activity of I3C is considered indirect since...

The effect of nitrogen, irrigation, and cultivation on Pinot noir juice and wine composition from the Willamette Valley, Oregon

Creator:: Wall, Katherine Elizabeth
Abstract:: This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...

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...
