¡Sí, Se Puede! Yes, You Can! Employing a Personal Testimonio to Show Young Latinx Students and Families That Their Dreams of College are Well Within Reach

Creator:: Curtis, Lorenzo Michael
Abstract:: From my personal experiences, I’ve noticed that Latinx students and families are most receptive to college-related information communicated as anecdotes. Latinx students are among the most poorly represented demographic at universities nationwide, which I believe can be mitigated through calculated efforts to increase collegiate literacy and understanding. This project is...

Breeding and genetics of lilacs and hardy hibiscus

Creator:: Lattier, Jason D.
Abstract:: Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

Total synthesis of phorboxazole A

Creator:: Lee, Tae Hee
Abstract:: The total synthesis of a highly potent cytotoxic marine natural product, phorboxazole A, is described. Both a palladium(II)-mediated and a palladium(II)-catalyzed intramolecular alkoxycarbonylation were used as key steps for the preparation of the two cis-2,6-disubstituted tetrahydropyran rings (C22-C26 and C11-C15) of phorboxazole A. The synthesis used a convergent approach involving...

Studies of non-mevalonate isoprenoid biosynthesis : the 1-deoxy-D-xylulose-5-phosphate isomeroreductase (DXR) mediated reaction

Creator:: Woo, Youn-Hi
Abstract:: This dissertation details the investigation of an alternate pathway to isoprenoids that occurs in plants and microorganisms, the non-mevalonate pathway. This exploration of the pathway focuses on the second step, the conversion of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methylerythritol-4-phosphate (MEP) by the enzyme DXP isomeroreductase (DXR). These studies led to an appreciation...

Precursor-directed Biosynthesis and Total Synthesis of Aniline-containing Natural Products from the Endophytic Fungus Chalara sp. 6661

Creator:: Khoshbakht, Mahsa
Abstract:: Chalaniline A, an unusual xanthone-like aminofulvene with modest cytotoxicity, and chalaniline B [1-anilino-2,8-dihydroxy-3-(hydroxymethyl)xanthone], an antibacterial aminoxanthone, were previously isolated by Loesgen and coworkers from vorinostat-treated Chalara sp. 6661. Of note, the anilino moiety found within both chalaniline structures originates from biotransformation of the HDAC inhibitor vorinostat (SAHA, suberanilohydroxamic acid) by...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

Total Synthesis of Isotopologues of Xanthohumol and its Congeners for Biological Studies

Creator:: Plagmann, Layhna S.
Abstract:: Xanthohumol [XN, (E)-6´-methoxy-3´-(3-methylbuten-2-yl)-2´,4´,4´´-trihydroxychalcone], the principal prenylated chalcone from hops, and its 2,3-dihydro- (DXN) and O6-desmethyl-2,3-dihydro- (DDXN) congeners, are of potential utility for the amelioration of metabolic syndrome; however, their complex bioactivity profiles cannot be properly studied and understood without access to appropriately produced synthetic materials. In the first part of...

Part I: Synthetic Studies toward C10-functionalized Lycopodium Alkaloids. Part II: Exploration of the Pummerer Cyclization and Its Application to the Total Syntheses of the Abietane Diterpenoids

Creator:: Li, Xin
Abstract:: This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

The role of innate immunity in cnidarian-dinoflagellate symbiosis

Creator:: Poole, Angela Z.
Abstract:: Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....
