  1. 6. Studies of Cytotoxic Compounds of Natural Origin and their Mechanisms of Action

    Författare :Jenny Felth; Lars Bohlin; Joachim Gullbo; Ulf Göransson; Thomas Efferth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxic; cardiac glycoside; gambogic acid; cancer; mechanism of action; Pharmacognosy; Farmakognosi; Pharmacognosy; Farmakognosi;

    Sammanfattning : Cancer incidence is increasing and novel anticancer drugs with new mechanisms of action are essential for future chemotherapeutic treatment. Natural products have historically played an important role in the development of anti-cancer drugs and have potential to do so also in the future. LÄS MER

  3. 7. Structure and Activity of Circular Plant Proteins : Cytotoxic Effects of Viola Cyclotides

    Författare :Anders Herrmann; Ulf Göransson; Lars Bohlin; Douglas Kinghorn; Uppsala universitet; []
    Nyckelord :Pharmacognosy; cyclotide; cytotoxic; anti-tumour; macrocyclic; cyclic cystine knot; Alpine violet; Sweet violet; Viola; Violaceae; chemical modifications; structure-activity studies; mass spectroscopy; cDNA clones; Farmakognosi;

    Sammanfattning : Cyclotides are a family of small and macrocyclic proteins that have been found in Violacaee and Rubiaceae plant species. These proteins contain a cystine knot: two disulfides bonds together with their connecting peptide backbone form an embedded ring which is penetrated by a third disulfide bond. LÄS MER

  4. 8. Polyporoid fungi of Tanzania : Taxonomy, transcriptomics and biochemical analyses of Kusaghiporia usambarensis and Piptoporellus baudonii

    Författare :Juma Mahmud Hussein; Sanja Tibell Savić; Donatha Tibuhwa; Christina Wedén; Ulf Göransson; Jan Stenlid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematics; Laetiporaceae; pharmacognosy; cysteine-rich peptide; baudonii; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Polyporoid fungi refers to basidiomycetes with fruiting bodies with the hymenium located to the inner surfaces of pores or narrow tubes. The majority of polyporoids belongs to Polyporales. Most Polyporales are saprobes, but some are plant pathogens. LÄS MER

  5. 9. Studies on cysteine-rich peptides from Nemertea and Violaceae : Proteomic and transcriptomic discovery and characterization

    Författare :Erik Jacobsson; Ulf Göransson; Håkan S. Andersson; Robert Burman; Espen Hansen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptide toxin; cystine knot; nemertide; cyclotide; nemertea.; Farmakognosi; Pharmacognosy;

    Sammanfattning : The overall aims of the projects included in this thesis were to discover, synthesize and characterize disulphide-stabilized peptides from marine worms (Nemertea sp.) and plants (Viola sp.). LÄS MER

  7. 10. Micro-Structure Modelling of Acoustics of Open Porous Material

    Författare :Eva Lundberg; Peter Göransson; Per Wennhage; Ulf Orrenius; Camille Perrot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; porous material; flow resistivity; micro-structure; anisotropic; foam; strut; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Transportation is a large and growing part of the world’s energy consumption. This drives a need for reduced weight of rail vehicles, just as it does for road vehicles. In spite of weight reductions, the vehicle still has to provide the same level of acoustic comfort for the passengers. LÄS MER
