  1. 1. Clinical and Biological Patterns in Soft Tissue Sarcoma

    Författare :Emelie Styring; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiosarcoma; radiation-associated sarcoma; irradiated; RET; KIT; MYC.;

    Sammanfattning : Soft tissue sarcomas (STSs) are rare malignant tumors, of which 3/4 are high-grade and 1/3 metastasize. For optimal management, STSs should be treated at multidisciplinary sarcoma centers. LÄS MER

  3. 2. Studies of the two redox active tyrosines in Photosystem II

    Författare :Nigar Ahmadova; Fikret Mamedov; Stenbjörn Styring; Robert Burnap; Uppsala universitet; []
    Nyckelord :Photosystem II; Tyrosine Z and D; proton-coupled electron transfer;

    Sammanfattning : Photosystem II is a unique enzyme which catalyzes light induced water oxidation. This process is driven by highly oxidizing ensemble of four Chl molecules, PD1, PD2, ChlD1 and ChlD2 called, P680. Excitation of one of the Chls in P680 leads to the primary charge separation, P680+Pheo-. LÄS MER

  4. 3. EPR Studies of Photosystem II : Characterizing Water Oxidizing Intermediates at Cryogenic Temperatures

    Författare :Kajsa G.V. Havelius; Stenbjörn Styring; Holger Dau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : The principles of natures own light-driven water splitting catalyst, Photosystem II (PSII), can in the future inspire us to use water as electron and proton source to generate light-driven H2 production. To mimic this challenging step, it is important to understand how the enzyme system can oxidize water. LÄS MER

  5. 4. The Far-Red Limit of Photosynthesis

    Författare :Fredrik Mokvist; Stenbjörn Styring; Tomáš Polívka; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Far-red light; Photosystem I; Photosystem II; P700; P680; EPR; Charge Separation; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Sammanfattning : The photosynthetic process has the unique ability to capture energy from sunlight and accumulate that energy in sugars and starch. This thesis deals with the light driven part of photosynthesis. LÄS MER

  7. 5. Photosynthetic water oxidation : the function of two extrinsic proteins

    Författare :Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; Plant physiology; Växtfysiologi;

    Sammanfattning : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. LÄS MER
