  1. 1. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration

    Detta är en avhandling från Stockholm : Institutionen för neurokemi

    Författare :Jonas Hälldin; Tiit Land; Paolo Arosio; [2007]

    Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER

  4. 4. Compounds with Non-Buttressed Metal-Metal Bond between Platinum and Thallium. Model Systems for Photoinduced Two-Electron-Transfer

    Detta är en avhandling från Stockholm : Kemi

    Författare :Mikhail Maliarik; [2001]
    Nyckelord :thallium; platinum; cyanide; metal-metal bond; non-buttressed; heterometallic; photoinduced; electron transfer; redox reaction; NMR; chemical shift; spin-spin coupling constant; Raman; EXAFS; X-ray diffraction; equilibrium; oxidation state; oxidative;

    Sammanfattning : A new family of oligonuclear cyano compounds incorporatingtransition (Pt) and main group (Tl) metals bound with anon-buttressed Pt-Tl bond was synthesised in aqueous solution.The metal-metal linkage is formed in the reaction betweenplatinum and thallium in their stable oxidation forms, Pt(II)and Tl(III), orvice versa: Pt(IV) and Tl(I).

    Sammanfattning : Stroke is a major cause of death and adult disability in the western world. Most often, stroke is caused by the occlusion of a brain artery. Within the perfusion territory of the occluded vessel, various degrees of necrotic and delayed programmed cell death will occur if the occlusion persists, leading to expanding tissue damage. LÄS MER
