  2. 1. The role of reactive oxygen species in traumatic brain injury : Experimental studies in the rat

    Author : Niklas Marklund; Uppsala universitet; []
    Keywords : Medical sciences; Apoptosis; CBF; controlled cortical contusion injury; 3; 4-dihydroxybenzoate; fluid percussion injury; glucose; 4-hydroxybenzoate; microdialysis; Morris Water Maze; neuroprotection; nitrones; PBN; rat; reactive oxygen species ROS ; salicylate; S-PBN; TBI; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Neurosurgery; neurokirurgi;

    Abstract : Traumatic brain injury (TBI) is a major cause of mortality and disability. As common sequelae in survivors of TBI are disabling functional, emotional and cognitive disturbances, improved treatment of TBI patients is urgently needed. At present, no neuroprotective pharmacological treatment exists. READ MORE

  4. 2. Asymmetric 1,3-Dipolar Cycloaddition Reactions of Azomethine Ylides, Thiocarbonyl Ylides, and Nitrones

    Author : Staffan Karlsson; KTH; []
    Keywords : ;

    Abstract : This thesis describes the development of methods for thepreparation of chiral non-racemic substituted pyrrolidines,tetrahydrothiophenes, and isoxazolidines. This has beenaccomplished by using asymmetric intermolecular 1,3-dipolarcycloaddition reactions of azomethine ylides, thiocarbonylylides and nitrones, respectively, with variousdipolarophiles.
