  1. 21. Equilibrium studies of ternary aluminium(III) hydroxo complexes with ligands related to conditions in natural waters

    University dissertation from Umeå : Umeå universitet

    Author : Lars-Olof Öhman; Umeå universitet.; [1983]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aqueous solution; binary and ternary hydroxo complexes of Al3 ; carbonic acid; citric acid; phenolic ligands; emf-titrations; equilibrium analysis; model calculations towards natural waters;

    Abstract : The thesis is a summary and discussion of eight papers. During the last decades, precipitation has become increasingly acidic due to the extensive use of fossil fuels. In areas of poorly buffered bedrocks, e.g. READ MORE

  2. 22. Modelling of melanocortin receptors and their ligands

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peteris Prusis; Uppsala universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; melanocortin; G-protein coupled receptor; modeling; three-dimensional; QSAR; chemometrics; Farmaceutisk biovetenskap; PHARMACY Biopharmacy; FARMACI Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : Five subtypes of melanocortin receptors (MC1-MC5R) mediate a wide range of physiological actions, including control of skin tanning, inflammation and food intake. The natural ligands for these receptors are the melanocortins, which are linear peptides 11 to 39 amino acids long. READ MORE

  3. 23. Opioid ligands and receptors of the joint

    University dissertation from Stockholm : Karolinska Institutet, Department of Molecular Medicine and Surgery

    Author : Jonas Bergström; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Opioid peptides; enkephalin; opioid receptors; joint; primary afferents; synovial lining cells; vascular smooth muscle; arthritis; osteoarthrosis; immunohistochemistry; radioimmunoassay; RTPCR; binding assay;

    Abstract : The aim was to explore the occurrence of an opioid system in joints. Thus, joint tissues from rats with and without arthritis and also from patients with knee osteoarthrosis were investigated by EM, immunohistochemistry, RIA, HPLC, receptor binding assay and RT-PCR. READ MORE

    Abstract : Popular Abstract in Swedish Asymmetrisk katalys är ett omfattande forskningsområde där ett flertal olika typer av enantioselektiva katalysatorer har utvecklats och använts i en mängd olika kemiska reaktioner med varierande resultat. Det finns ingen katalysator som fungerar lika väl i alla applikationer, utan resultaten varierar från fall till fall och för vissa typer av substrat behövs det därför alternativa lösningar för att erhålla önskad selektivitet.
