  1. 1. Development of a Sel-tag for multimodality imaging and studies of mammalian thioredoxin reductase 1

    Författare :Qing Cheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Selenocysteine (Sec; U in one-letter code), the 21st amino acid existing in all selenoproteins, has unique biochemical properties due to its selenium atom, including a low pKa and a high reactivity with many electrophilic agents. When a selenoprotein is translated, the insertion of Sec occurs at a UGA codon, normally yielding translational termination. LÄS MER

  3. 2. Surface complexation in natural particle suspensions

    Författare :Qing Du; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : This thesis is a summary of our studies on (i) the proton and copper adsorption at aqueous illite surfaces, (ii) the proton and copper complexation of humic substances (fulvic acid FA and humic acid HA), (iii) the interaction between illite and fulvic acid, and (iv) the copper complexation behaviors in illite-FA bi-complexant systems. These particular studies were designed to help us develop a framework for modelling heavy metal complexation/adsorption mechanisms at natural particle surfaces. LÄS MER

  5. 4. Revisiting Optimal Link Activation and Minimum-Time Scheduling in Wireless Networks

    Författare :Qing He; Di Yuan; Vangelis Angelakis; Erik Bergfeldt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the popularity of wireless communications in the last two decades, data traffic is exponentially increasing and requests high speed transmission. However, the resources, in particular, spectrum and energy, are limited. LÄS MER

  7. 5. Endothelin-1-immunoreactive protein and neuroendocrine differentiation and nerve supply in human non-neoplastic and neoplastic adrenal cortex : Immunohistochemical, ultrastructural, and biochemical findings

    Författare :Qing Li; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; adrenal cortex; human; endothelin-related protein; innervation; neuroendocrinedifferentiation; immunohistochemistry; electron microscopy; biochemistry; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : The occurrence and distribution of endothelin (ET)-1-immunoreactive (ir) protein, neuro-endocrine markers and neurohormonal peptides in endocrine cells and nerves in human non-neoplastic and neoplastic adrenal cortex are described.ET-1-ir cell groups were regularly seen in human adrenal cortex, mainly in zona fasciculata, but not in the medulla.
