  2. 1. Coagulation and inflammation in experimental endotoxemia in vitro and in vivo : monitoring method and effects of nicotinamide

    Author : Johanna S Ungerstedt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Sepsis; endotoxin; tissue factor; cytokines; nicotinamide; coagulation; inflammation;

    Abstract : In gram negative sepsis, endotoxin from the bacterial membrane elicits proinflammatory and procoagulant host responses. Sepsis and its frequent complication disseminated intravascular coagulation (DIC) are leading causes of morbidity and mortality in the intensive care. READ MORE

  4. 2. Predicting oral performance of lipid-based formulations using in vitro methods

    Author : Oliver Hedge; Christel Bergström; Frédéric Carriere; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid-based formulation s ; SEDDS; artificial membrane s ; cell monolayer s ; oral drug delivery; lipolysis; permeation; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Oral administration of drugs is widely considered preferable to other methods by end-users and healthcare providers alike; however, not all drug compounds are inherently suited for it because some molecules are not well-absorbed by the intestine. Good absorption requires both dissolution and permeation. READ MORE

  5. 3. Heteroatom-doped porous carbon materials derived from poly(ionic liquid)s and their composites for battery and catalytic applications

    Author : Sadaf Saeedi Garakani; Jiayin Yuan; Diego Cazorla-Amorós; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heteroatom doped carbon; Porous carbon membrane; Poly ionic liquid -derived carbon; Wood-derived carbon; Catalytic activity; Peroxidase-like activity; lithium sulfur battery; materialkemi; Materials Chemistry;

    Abstract : In the past decade, there has been significant interest in heteroatom-doped porous carbons, driven by the distinctive and adjustable physical and chemical properties that they exhibit across scales, from the atomic to the macroscopic level. Particularly, attributes such as conductivity, electron density, high specific surface area, hierarchical pore structure, and oxidation resistance offer a wide range of characteristics for diverse applications.

  6. 4. Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis

    Author : Joakim Högblom; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Hydrogen; EPR; Cobalt; Biokemi; metabolism; Biochemistry;

    Abstract : The work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. READ MORE

  7. 5. Quantum Coherence for Light Harvesting

    Author : David Palecek; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Abstract : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. READ MORE
