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

    Författare :Johan Kjellström; Bröstcancer-genetik; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Samordnad individuell plan (SIP) : Professionellas samt barn och föräldrars erfarenheter

    Författare :Erik Nordström; Sofia Kjellström; Berith Hedberg; Iréne Josephson; Johan Berlin; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduktion. Många barn och unga idag har så pass komplexa behov att de behöver samtidiga insatser från olika huvudmän. Insatserna blir alltmer specialiserade och fragmenterade, vilket kräver att professioner inom hälso- och sjukvård, socialtjänst och skola samverkar. LÄS MER

  4. 3. High-resolution simulations of two cold palaeo climates in Europe : MIS 3 and LGM

    Författare :Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Anders Moberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palaeo climate; climate modelling; proxy data; LGM; MIS 3; meteorologi; Meteorology;

    Sammanfattning : The study of past climate is important because it increases our understanding of how the climate system works. Past climate is often reconstructed by using proxies (that is observations of things that tell something about past climate, for example tree rings, pollen in lake sediments and fossils). LÄS MER

  5. 4. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

    Författare :Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. LÄS MER

  7. 5. Exterior Colours at Rural Dwellings in Southern Sweden during the 19th Century - To increase knowledge regarding local differentiations

    Författare :Richard Kjellström; Bebyggelsevård; []
    Nyckelord :19th century; local colour schemes; rural; Johan Jöran Öller; SEM analysis; cross-section; exterior colour; farmhouses; dwellings;

    Sammanfattning : Abstract The project’s main objective is to verify the existence of local colours and colour schemes in the exteriors of buildings. The research focused on 19th century dwellings in the rural areas of southern Sweden. LÄS MER
