  2. 11. Autoantibodies in congenital heart block

    Author : Robert Klauninger; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neonatal lupus erythematosus (NLE) affects neonates of Ro/SSA and La/SSB positive women. NLE is associated with several clinical manifestations including skin rash, cytopenia and congenital heart block (CHB). CHB is the most severe manifestation which can develop into a lethal atrioventricular (AV) block. READ MORE

  4. 12. Risk factors for autoimmune-mediated congenital heart block

    Author : Sabrina Meisgen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Placental transfer of maternal Ro/SSA and La/SSB autoantibodies during pregnancy is associated with conduction disturbances and inflammation in the developing fetal heart, termed autoimmune-mediated congenital heart block (CHB). Maternal Ro/SSA and La/SSB autoantibodies are the main risk factors associated with the fetal cardiac manifestations to date, however, the low recurrence rate despite persisting autoantibodies in subsequent pregnancies indicates that additional factors determine fetal susceptibility.

  5. 13. Induction of apoptosis in relation to chromatin structure and inhibition of replication by DNA damage from ionizing radiation

    Author : Jesper Torudd; Mats Harms-Ringdahl; Mats Ljungman; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; DNA-loop; replication fork; Toxicology; Toxikologi;

    Abstract : The theme of this thesis has been chromatin organization ranging from methodological studies to involvement in apoptotic response. The aims have been: (i) to compare the information obtained by the AVTD method and comet assay concerning DNA-loop organization, (ii) to test the hypothesis that DNA-loop relaxation could be the triggering signal for induction of apoptosis in G0-lymphocytes, and (iii) to study the dose response for inhibition of the replication fork movement and pathways for the DNA repair process at the replication fork.

  6. 14. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions

    Author : Gandharva Appagere; Maria Doncel Monasterio; Per-Erik Tegnér; Michael Papenbrock; Andreas Heinz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hyperons; multi-strangeness; neutron-stars; cross-section; Lambda-lambda; Physics; fysik;

    Abstract : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. READ MORE

  7. 15. Pelagic Fish Distribution and Dynamics in Coastal Areas in the Baltic Sea Proper

    Author : Thomas Axenrot; Sture Hansson; Stein Kaartvedt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; herring; Baltic; hydroacoustic; distribution; behaviour; Biology; Biologi;

    Abstract : Pelagic fish distribution and diel behaviour patterns were studied in coastal areas in the north-western Baltic Sea Proper to understand more about how fish distribution and behaviour might affect planning and analyses of results of hydroacoustic surveys (Papers I and II). The vertical distribution of fish at night from spring to autumn showed seasonal and annual trends that could be explained by predictable and consistent seasonal changes, e. READ MORE
