  2. 1. Minimally invasive aortic valve replacement

    Author : Magnus Dalén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Minimally invasive aortic valve replacement (AVR) through a ministernotomy has been developed as an alternative approach to conventional full sternotomy AVR. During recent years, sutureless aortic bioprostheses were introduced with the aim to facilitate implantation, especially in minimally invasive procedures. READ MORE

  4. 2. Pharmacokinetic consequences of CYP2D6 genotypes with emphasis on gene duplication / amplification

    Author : Per Dalén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Drug metabolism; CYP2D6. debrisoquine; nortriptyline; quinidine; genotype; phenotype; cytochrome P450; gene duplication; gene amplification;

    Abstract : The relationship between the major Caucasian and Oriental CYP2D6 genotypes and the disposition of two CYP2D6 substrates nortriptyline and debrisoquine was investigated. Caucasians with 0, 1, 2, 3/4 and 13 functional CYP2D6-genes as well as Chinese and Korean subjects homo- and heterozygous for the CYP2D6*1 and CYP2D6*10 alleles were included. READ MORE

  5. 3. Standing with and without vibration in children with severe cerebral palsy

    Author : Ylva Dalén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Children with severe cerebral palsy (CP) risk fragile bones, fractures and hip dislocation due to disuse. A standing shell allows these children weight bearing in an upright position. Recommended standing time is one to two hours/day but evaluations are lacking. READ MORE

  6. 4. Price measurement and index construction : some contributions to theory and application

    Author : Jörgen Dalén; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Konsumentprisindex;

    Abstract : Four different problems are treated, all concerned with problems arising when compiling price indexes in official statistics. One deals with the computation of so called elementary aggregates, low level indexes for single products, when proper weights for the observations are not available. READ MORE

  7. 5. Distribution and abundance of genetic variation in the arctic fox

    Author : Love Dalén; Anders Angerbjörn; Robert K. Wayne; Stockholms universitet; []
    Keywords : population genetics; DNA; ecology; population history; gene flow; Alopex lagopus;

    Abstract : This thesis investigates how changes in population size and spatial movements of individuals have shaped the distribution and abundance of neutral genetic variation in the arctic fox. This is done through mitochondrial and microsatellite DNA analyses on samples covering most of the species’ distribution, but with special emphasis on Scandinavia. READ MORE
