  1. 1. Recognition and Separation of Hemoglobin Variants via Molecularly Imprinted Polymers

    Författare :Ka Zhang; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; molecularly imprinted polymers; haptoglobin; protein purification; chromatography glyceraldehyde 3-phosphate dehydrogenase; Pickering emulsion;

    Sammanfattning : Hemoglobin (Hb) is the predominant protein in red blood cells with allosteric regulation mechanisms for delivering oxygen between the lungs and tissues. After the 1980s, concentrated research on modified Hb emerged because of the necessity for the development of a blood substitute (oxygen carrier). LÄS MER

  3. 2. Role of cytokines in experimental neurodegenerative and neuroinflammatory disorders

    Författare :Xing-Mei Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Altered expression of cytokines in response to body injury has diverse actions that can exacerbate, mediate, reduce or inhibit neuronal and myelin damage as well as influence the disease development in a variety of nervous system disorders, such as Alzheimer s disease (AD), multiple sclerosis and Guillain-Barré Syndrome (GBS). In these studies, we attempted to explore the possible roles of tumor necrosis factor (TNF)-α and interleukin (IL)-18 in experimental neurodegenerative and neuroinflammatory disorders. LÄS MER

  4. 3. Dynamics and Applications of Long Josephson Junctions

    Författare :Yongming Zhang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The first object of this work is to theoretically study the effects of tunnel junction parameters on flux-flow Josephson oscillators (FFOs) by numerical simulation and to experimentally study the rf properties of FFOs by integrating them together with an SIS (superconductor-insulator-superconductor) mixer/detector on a chip. By using a CAD modeled integrated sub-mm wave receiver, the composite linewidth of two FFOs was measured to be less than 2. LÄS MER
