  2. 1. New Methods for the Synthesis of Vicinal Stereocenters : Palladium-Catalyzed Domino Reactions and Asymmetric Transfer Hydrogenation

    Author : Brinton Seashore-Ludlow; Somfai Peter; Kevin Booker-Milburn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric synthesis; domino reactions; palladium-catalyzed reactions; oxindoles; amino alcohols;

    Abstract : In this thesis the synthesis of vicinal stereocenters is investigated in two distinct contexts, namely the construction of 3,3-disubstituted oxindoles and the synthesis of b-hydroxy-a-amino acids. Both scaffolds are prevalent in a range of natural products and biologically relevant compounds and, therefore, methods for their synthesis are of great import. READ MORE

  4. 2. Preclinical tumor-immune modeling : For the identification of immunomodulatory drugs

    Author : Tove Selvin; Mårten Fryknäs; Rolf Larsson; Claes Andersson; Malin Jarvius; Brinton Seashore-Ludlow; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immuno-oncology; anti-cancer drugs; preclinical modeling; drug screening; repurposing;

    Abstract : For a long time, the field of cancer research was dominated by a tumor cell-centric view. That, however, changed once it became recognized that medical cancer treatment is largely influenced by the combined effect exerted on both cancer and immune cells. READ MORE

  5. 3. Diversity and Life Habits of Silurian Strophomenide Brachiopods of Gotland

    Author : Ole Andreas Hoel; Lars E. Holmer; Michael Bassett; David A. T. Harper; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Gotland; Silurian; brachiopod; functional morphology; ecology; Llandovery; Wenlock; Ludlow; Strophomenoidea; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : The Superfamily Strophomenoidea is a very diverse group of brachiopods in the Early Palaeozoic. In the Silurian succession on Gotland, they are among the most easily identifiable, and commonly found fossils. READ MORE

  6. 4. Silurian Carbonate Platforms of Gotland, Sweden - Archives of Local, Regional and Global Environmental Changes

    Author : Mårten Eriksson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Sedimentology; fysisk geografi; Geologi; physical geography; Geology; Gotland; Silurian; Facies; Carbonate platforms; Sequence stratigraphy; Stable isotopes; Palaeoclimate;

    Abstract : This thesis treats the Silurian carbonate platforms of Gotland, Sweden, which formed close to the equator within the East Baltic Basin. Three different time intervals, all involving changes in facies composition and structure of the platforms, have been studied; Late Homerian, latest Homerian ? earliest Gorstian, and late Ludfordian, respectively.

  7. 5. Reef biostromes and related facies from the Middle Silurian of Gotland, Sweden

    Author : Olof Sandström; Geologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; stromatoporoids; facies analysis; palaeobiology; Reefs; biostromes; Geologi; fysisk geografi;

    Abstract : Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. READ MORE
