  1. 1. Vanadate and Peroxovanadate Complexes of Biomedical Relevance A speciation approach with focus on diabetes

    University dissertation from Umeå : Kemi

    Author : András Gorzsás; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; vanadium; hydrogen peroxide; lactate; citrate; phosphate; alanyl serine; picolinic acid; speciation; formation constants; equilibrium; solution structure; potentiometry; NMR 51V; 31P; 13C; 1H ; Oorganisk kemi; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain.

    Abstract : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  4. 4. Structure/function relationships of inorganic phosphate transporters

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Dieter R. Samyn; Linnéuniversitetet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic phosphate; transporters; Saccharomyces cerevisiae; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Biokemi; Biochemistry;

    Abstract : Of the many nutrients that make the metabolic clock tick, inorganic phosphate fulfills an essential role in all yeast (and other organisms), being necessary for both structural and metabolic purposes. In order to transport phosphate into the cell interior, Saccharomyces cerevisiae makes use of two systems, comprising high- or low-affinity transporters, which are responsible for the cellular accumulation of inorganic phosphate.

  5. 5. The Challenge of Probing Lithium Insertion Mechanisms in Cathode Materials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Höwing; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Li-ion battery; cathode materials; insertion mechanism; single-crystal X-ray diffraction; vanadium oxide; lithium iron phosphate; Oorganisk kemi; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi;

    Abstract : The Li-ion battery has, from its commercialisation in the early 1990's, now become the most widely used power source for portable low-power electronics: laptops, cellular phones and MP3-players are a few examples. To further develop existing and find new electrode materials for these batteries, it is vital to understand the lithium insertion/extraction mechanisms taking place during battery operation. READ MORE
