  2. 1. Bark Biorefinery : Isolation, Characterization and Application

    Author : Isabella Kwan; Monica Ek; Åsa Emmer; Anette Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sustainability; bark; biorefinery; Norway spruce; nanocellulose; Pickering emulsion; organosolv; extraction; lignin; Hållbarhet; bark; bioraffinaderi; gran; nanocellulosa; Pickering emulsioner; organosolv; extraktion; lignin; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. READ MORE

  4. 2. The evolutionary ecology of plant reproductive diversity and floral signals : Mating system and floral scent in Arabis alpina

    Author : Hampus Petrén; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabis alpina; floral scent; intraspecific variation; mating system; parental conflict; phenotypic plasticity; phenotypic selection; reproductive isolation; speciation; volatile organic compound VOC ;

    Abstract : Flowering plants display an extraordinary floral- and reproductive diversity. Variation in the size, shape, colour and scent of flowers, and in systems and strategies of mating, is ubiquitous in comparisons of different species, but also exists among different conspecific populations.

  5. 3. Nitration of Oxo-pyramidines and Oxo-imidazoles

    Author : Abraham Langlet; Christina Moberg; Jan Bakke; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; explosives; gem-Dinitro compounds; Dinitromethane; Nitroform; Organic chemistry; Organisk kemi;

    Abstract : This thesis is mainly focused on the reactions of oxo-pyrimidines and oxo-imidazoles with nitric acid in sulfuric acid and properties of the gem-dinitro products formed in this process. Low temperature nitrations of 2-methylimidazoles produced – in addition to the known 2-methyl-5(4)-nitroimidazole – 2-(dinitromethylene)-5,5-dinitro-4-imidazolidinone and parabanic acid. READ MORE

  6. 4. Studies on anti-leukemic terpenoids from medicinal mushrooms and marine sponges with ChemGPS-NP-based targets investigation of lead compounds

    Author : Kuei-Hung Lai; Anders Backlund; Christina Wedén; Fang-Rong Chang; Yang-Chang Wu; Nicholas Oberlies; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ChemGPS-NP analysis; antileukemic agents; lanostanoids; sesterterpenoids; manoalide; Pharmacognosy; Farmakognosi;

    Abstract : This thesis investigates the anti-leukemic activity of terpenoids isolated from medicinal mushrooms and marine sponges, as well as their possible targets and mechanisms of action.In the first section, we focused on studying the triterpenoidal components of three triterpenoid-enriched medicinal mushrooms Antrodia cinnamomea, Ganoderma lucidum, and Poria cocos, which have been used in folk medicine for centuries and also developed into several contemporary marketed products.

  7. 5. Characterization of parameters influencing intracellular bioavailability and prediction of intracellular drug exposure

    Author : Andrea Treyer; Per Artursson; Gert Fricker; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular drug bioavailability; unbound drug concentration; drug disposition; ADME; drug transport; drug metabolism membrane partitioning; phospholipid; drug-drug interaction; antisense oligonucleotide; cell-penetrating peptide; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : This thesis work investigates factors influencing intracellular drug disposition. An experimental method for measurement of intracellular bioavailability (Fic), was used throughout. Fic is defined as the ratio between the unbound drug concentration inside the cell and the compound concentration in the cell exterior. READ MORE
