2. 1. Clinical factors and outcome in T-cell lymphoma: a population-based perspective

   Author : Fredrik Ellin; Tumörmikromiljö; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T-cell Lymphoblastic Lymphoma; peripheral T-cell lymphoma; prognostic factors; autologous stem cell transplantation; central nervous system relapse; comorbidity;

   Abstract : The heterogeneous group of T-cell lymphomas consist mostly of aggressive diseasess, with generally unfavourable outcome compared to aggressive B-cell lymphomas following similar therapy. This thesis focus on outcome and risk factors for inferior survival, in an unselected population-based cohort of T-cell lymphoma patients. READ MORE

4. 2. Epidemiological and clinical aspects of T-cell lymphoma

   Author : Henrik Cederleuf; Medicinsk onkologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; population-based; peripheral T-cell lymphoma; Anaplastic large cell lymphoma; angioimmunoblastic; elderly; ASCT; comorbidity; prognostic factors; follow-up; limited stage; etoposide; CHOP; overall survival; radiotherapy;

   Abstract : T-cell lymphoma (TCL) is a rare group of malignancies and one of the important aims in this thesis has been to broaden the general knowledge of TCL with descriptive patient data. Main focus has been to examine prognosticfactors for overall survival (OS) and progression-free survival (PFS), and to evaluate different treatment approaches and follow-up (FU) after treatment.

5. 3. Cationic Interactions with Nucleic Acids With Focus on Anticancer Active Platinum(II) Complexes

   Author : Åse Sykfont Snygg; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-line cleavage; Cisplatin; oxaliplatin; circular dichroism; DENSPM; polyamines; siRNA; pseudoknot; RNA; thermal melting; anticancer active Pt II complex; DNA;

   Abstract : It is well documented that the antitumour activity of the Pt(II)-complex cisplatin, and similar anticancer active complexes, is a result of metalation of DNA, and thereby inhibition of cell proliferation. Since nucleic acids are polyanions at physiological pH, the rate of adduct formation with positively charged complex, as the hydrolyzed Pt(II) complexes studied in this work, is influenced by the ionic environment surrounding the polymer.

6. 4. Platinum(II) and Palladium (II) Complexes with Group 14 and 15 Donor Ligands. Synthesis, Structure and Substitution Mechanisms

   Author : Ola Wendt; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanism; kinetics; substitution; platinum; palladium; aryl; silyl; nitrile; triphenylstibine; NMR; IR; Raman; X-ray crystallography; stopped-flow; synthesis; Inorganic chemistry; Oorganisk kemi;

   Abstract : The present thesis deals with Pd(II) and Pt(II) complexes with group 14 and 15 donor ligands. Such complexes have been prepared and investigated mainly with regard to their ground state structures and the mechanism according to which they undergo substitution. READ MORE

7. 5. Interactions of Anticancer Active Platinum(II) Complexes with DNA

   Author : Johan Kjellström; Bröstcancer-genetik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; polyelectrolyte; medium effects; salt dependence; DSC; CD; HPLC; oligonucleotide; hairpin; DNA; anticancer active platinum II compounds; kinetics; mechanism; Oorganisk kemi; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Abstract : The kinetics and mechanism for interactions of the anticancer active platinum(II) complexes cis-[PtCl2(NH3)2)], cis-[PtCl2(NH3)(c-C6H11NH2)], and trans-[PtCl2-(NH3)(quinoline)] with DNA have been studied using a combination of HPLC, circular dichroism (CD), UV/vis spectroscopy, and differential scanning calorimetry (DSC). Reactions of the monoaqua forms (charge = +1) of these complexes with single-stranded DNA oligonucleotides, typically between 13-17 bases long, were found to depend on i) the composition of the reaction medium, ii) the exact nature and location of the platination target, and iii) on the DNA structure.
