  2. 6. The Mussel Adhesive Protein (Mefp-1) : A GREEN Corrosion Inhibitor

    Author : Fan Zhang; Jinshan Pan; Douglas C. Hansen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

    Abstract : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. READ MORE

  4. 7. Hankel operators and Plancherel formula

    Author : Genkai Zhang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We consider the natural unitary action of the group SU(d, 1) on the Hilbert space L2(B,d/j,\), where B is the unit ball of C , dfi\ is the measure K(z, z)~~*+ï dm(z), and K(z, z) the reproducing kernel of the Bergman space on B. For A >—1 and not an integer, a Plancherel formula is proved for this action and, in particular, an explicit formula for the correponding Plancherel measure is found. READ MORE

  5. 8. Chromatographic studies of interactions between solutes, lipid bilayers and the glucose transporter Glut1

    Author : Yanxiao Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : It is advantageous to analyze solute interactions with biological membranes by chromatography on stationary phases that mimic the membrane structures. In the present work, liposomes, proteoliposomes, human red cells and red cell membrane vesicles were immobilized for analyses ofinteractions between solutes (peptides, drugs, inhibitors and glucose), lipid bilayers and theglucose transporter Glut1.

  6. 9. Calcium-binding proteins as markers and functional determinants of neurons in pain networks

    Author : Mingdong Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The thesis focuses on the anatomical and cellular distribution of three EF-hand calcium binding proteins, secretagogin, neuronal calcium-binding protein 1 (NECAB1) and NECAB2 in dorsal root ganglia (DRGs) and spinal cord of three species, mouse, rat and human, and their possible roles in pathophysiological pain. In Paper I and Paper IV, we report that the expression of secretagogin is limited to a small subpopulation of peptidergic neurons in mouse and human DRGs expressing calcitonin generelated peptide (CGRP).

  7. 10. Cytokine induced airway hyperreactivity characterized in an in-vitro model of asthma

    Author : Yaping Zhang; Klinisk och experimentell allergiforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxicology; Farmakologi; farmakognosi; MAPK; TNF-alpha; 5-HT; Respiratory system; Andningsorganen; Pharmacological sciences; pharmacognosy; pharmacy; interleukin-1beta; hyperresponsiveness; endothelin-1; airway; bradykinin; toxikologi; farmaci;

    Abstract : Asthma is a chronic disorder of the lower airways, characterized by inflammation and hyperreactivity. Pro-inflammatory cytokines like tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) are known to play important roles in the pathogenesis, but our knowledge how these cytokines contribute to the development of airway hyperreactivity is limited.
