Compression of Coated Drug Beads for Sustained Release Tablet of Glipizide: Formulation, and Dissolution

Creator:: Nguyen, Chien, Christensen, J. Mark, and Ayres, James W.
Abstract:: A promising formulation of glipizide comprising compression of four-layer coated beads into tablets which has advantages of providing a lag time (~ 2 hours) before drug release, retaining sustained-release characteristics, and providing approximately zero-order drug release, with drug release nearly independent of paddle speeds of 50 and 100 rpm during...

Evaluating Drosophila suzukii immunomarking for mark-capture research

Creator:: Klick, Jimmy, Lee, Jana C., Hagler, James R., Bruck, Denny J., and Yang, Wei Q.
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae) utilizes ‘Himalaya’ blackberry, Rubus armeniacus Focke (Rosaceae), as a host and may invade berry and stone fruit crops from field margins containing this invasive weed. Laboratory and semi-field studies were conducted to determine (1) the persistence of protein marks including 10% chicken egg whites (egg...

Constraints on the Late Holocene Anthropogenic Contribution to the Atmospheric Methane Budget

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Metabolism of Nonesterified and Esterified Hydroxycinnamic Acids in Red Wines by Brettanomyces bruxellensis

Creator:: Schopp, Lauren M., Lee, Jungmin, Osborne, James P., Chescheir, Stuart C., and Edwards, Charles G.
Abstract:: While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids...

Pine Creek Conservation Area : 2013 mapping and monitoring report

Creator:: Nielsen, Eric M., Noone, Matthew D., Kagan, James S., and Lee, Matthew T.
Abstract:: Pine Creek Conservation Area (PCCA), just northeast of the John Day River in Wheeler County, Oregon, was acquired in 1999-2001 by the Confederate Tribes of Warm Springs with support from the Bonneville Power Administration (BPA), to mitigate for wildlife losses created by the large, hydropower Columbia River Dams, particularly the...

Total synthesis of the marine toxin phorboxazole A using palladium(II)-mediated intramolecular alkoxycarbonylation for tetrahydropyran synthesis

Creator:: Kuntiyong, Punlop, Lee, Tae Hee, Kranemann, Christian L., and White, James D.
Abstract:: The potent antitumor agent phorboxazole A was synthesized from six subunits comprising C1-C2 (115), C3-C8 (98), C9-C19 (74), C20-C32 (52), C33-C41 (84) and C42-C46 (85). Tetrahydropyrans B and C containing cis-2,6-disubstitution were fabricated via palladium(II)-mediated intramolecular alkoxycarbonylation which, in the case of tetrahydropyran C, was carried out with catalytic palladium(II)...

Genetic framework for flowering-time regulation by ambient temperature-responsive miRNAs in Arabidopsis

Creator:: Lee, Hanna, Yoo, Seong Jeon, Lee, Jeong Hwan, Kim, Wanhui, Yoo, Seung Kwan, Fitzgerald, Heather, Carrington, James C., and Ahn, Ji Hoon
Abstract:: Flowering is the primary trait affected by ambient temperature changes. Plant microRNAs (miRNAs) are small non-coding RNAs playing an important regulatory role in plant development. In this study, to elucidate the mechanism of flowering-time regulation by small RNAs, we identified six ambient temperature-responsive miRNAs (miR156, miR163, miR169, miR172, miR398 and...

An Estimate of Tidal Energy Lost to Turbulence at the Hawaiian Ridge

Creator:: Klymak, Jody M., Moum, James N., Nash, Jonathan D., Kunze, Eric, Girton, James B., Carter, Glenn S., Lee, Craig M., Sanford, Thomas B., and Gregg, Michael C.
Abstract:: An integrated analysis of turbulence observations from four unique instrument platforms obtained over the Hawaiian Ridge leads to an assessment of the vertical, cross-ridge, and along-ridge structure of turbulence dissipation rate and diffusivity. The diffusivity near the seafloor was, on average, 15 times that in the midwater column. At 1000-m...

Development of Biological Control of Tetranychus urticae (Acari: Tetranychidae) and Phorodon humuli (Hemiptera: Aphididae) in Oregon Hop Yards

Creator:: Woods, J. L., Dreves, Amy J., James, D. G., Lee, J. C., Walsh, D. B., and Gent, D. H.
Abstract:: The temporal development of biological control of arthropod pests in perennial cropping systems is largely unreported. In this study, the development of biological control of twospotted spider mite, Tetranychus urticae Koch, and hop aphid, Phorodon humuli (Schrank), in a new planting of hop in Oregon is described over a period...

Efficient Synthesis and In Vivo Incorporation of Acridon-2-ylalanine, a Fluorescent Amino Acid for Lifetime and FRET/LRET Studies

Creator:: Speight, Lee C., Muthusamy, Anand K., Goldberg, Jacob M., Warner, John B., Wissner, Rebecca F., Willi, Taylor S., Woodman, Bradley F., Mehl, Ryan A., and Petersson, E. James
Abstract:: The amino acid acridon-2-ylalanine (Acd) can be a valuable probe of protein conformational change because it is a long lifetime, visible wavelength fluorophore that is small enough to be incorporated during ribosomal biosynthesis. Incorporation of Acd into proteins expressed in E. coli requires efficient chemical synthesis to produce large quantities...
