Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Development and broad application of a mass spectrometry based metabolomics platform

Creator:: Kirkwood, Jay Steven
Abstract:: Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...

Characterization of the Mechanisms of Action and Molecular Targets of Hop-derived Flavonoids in the Mitigation of Obesity-related Metabolic Impairments

Creator:: Paraiso, Ines L.
Abstract:: Obesity is a complex multifactorial disease resulting from excessive energy intake compared to energy expenditure. The excess energy is mostly stored as fat in enlarged adipocytes, but some lipids may infiltrate other organs such as the liver to form ectopic fat. Adipose tissue and ectopic fat produce and secrete a...

Phyto-edaphic relationships and ecotypic development of Festuca idahoensis in eastern Oregon habitat types of Artemisia tridentata

Creator:: Doescher, Paul Steven
Abstract:: This research assessed certain specific plant-soil and community interrelationships in eastern Oregon habitat types dominated by subspecies of Artemisia tridentata. The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial grass-low shrub and low perennial grass-high shrub composition. Soil concentrations of total nitrogen, organic...

Optimal harvesting of continuous age structured populations

Creator:: Smith, Steven J.
Abstract:: We investigate the optimal harvesting strategies for McKendrick type population models. Models of this type endow the population with a continuous age structure. They consist of a partial differential equation with a boundary condition which involves an integral of the solution. We study two problems, the first concerns the yield...

Effect of defoliation treatments on forage quality, quantity, and species composition of a Lolium perenne (L.) - Trifolium subterraneum (L.) pasture

Creator:: Motazedian, Iraj
Abstract:: As part of investigations to adapt a suitable grazing system in western Oregon, this research was designed to monitor the effects of defoliation treatments on dry matter production, forage quality, regrowth after defoliation, and species composition of a Lolium perenne Trifolium subterraneum pasture for three consecutive growing seasons from 1980...

An observational study of the wind fields associated with GATE cloud clusters

Creator:: Tollerud, Edward I.
Abstract:: The wind and thermodynamic fields associated with eastern Atlantic cloud clusters are studied using radiosonde data from the Global Atmospheric Research Program Atlantic Tropical Experiment (GATE). These data are from the gridded set of winds prepared by Dr. Katsuyuki Ooyama (AOML-NOAA) and Dr. Jan-Hwa Chu (SSEC, University of Wisconsin, Madison)...

Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...
