  1. 1. Cyanide and central nervous system : a study with focus on brain dopamine

    Författare :Gudrun Cassel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Sammanfattning : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. LÄS MER

  4. 3. Cyanide in breath as a marker for cyanide poisoning

    Författare :Kristin Stamyr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Approximately 120 people die every year due to fires in Sweden. A majority of the fire victims die due to toxic fire gases. Carbon monoxide is often thought to be the major cause of death. Still, another very toxic fire gas, hydrogen cyanide, is formed when materials containing nitrogen burn, e. LÄS MER

    Sammanfattning : Epidemics of a permanent, non-progressive spastic paraparesis with sudden onset hasbeen reported from several rural areas of sub-Saharan Africa. Studies in East Africasuggested an association with dietary cyanide intake from unprocessed cassava. LÄS MER

  7. 5. New Methods for Chiral Cyanohydrin Synthesis

    Författare :Erica Wingstrand; Christina Moberg; Benjamin List; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acyl cyanides; asymmetric synthesis; biocatalysis; cyanide; cyanohydrins; dual activation; enzymes; high-throughput screening; Lewis acid; Lewis base; metal catalysis; minor enantiomer recycling; salen; titanium; Chemistry; Kemi;

    Sammanfattning : This thesis deals with method development in asymmetric catalysis and specifically syntheses of enantioenriched O-functionalized cyanohydrins. The first part describes the development of a method for the synthesis of O‑alkoxycarbonylated and O-acylated cyanohydrins. LÄS MER
