  2. 7. Time and general practice consultations : aspects of length, attendance and quality

    Författare :Sven-Olof Andersson; Bengt Mattsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General practice; primary health care; consultation; time; doctor-patient relation; satisfaction; primary care nurse; frequent attender;

    Sammanfattning : The consultation is the GP’s form of work. How long a consultation should be, and what short/long consultations imply with regard to the satisfaction of patient and doctor has been much debated. The aim of this thesis was to study consultations with regard to content and time consumption in a short term and long term perspective. LÄS MER

  3. 8. Urinary tract infections in primary health care in northern Sweden : epidemiological, bacteriological and clinical aspects

    Författare :Sven Ferry; Bengt Mattsson; Lars Burman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract infection UTI ; primary health care PHC ; epidemiology; clinical presentation; bacteriuria diagnosis; bacteriology; drug resistance; therapy;

    Sammanfattning : The epidemiology of urinary tract infection (UTI) in the population of Vännäs (8 000 inhabitants) was studied during one year. The annual incidence increased from 0.5% in the first decade of life to more than 10% in the age group 90-100 years. LÄS MER

  4. 9. A multivariate approach to QSAR

    Författare :Sven Hellberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; beta-adrenergic agents; haloalkanes; halogenated anesthetics; peptides; fractional factorial design; multivariate data analysis; principal components PC ; partial least squares PLS ;

    Sammanfattning : Quantitative structure-activity relationships (OSAR) constitute empirical analogy models connecting chemical structure and biological activity. The analogy approach to QSAR assume that the factors important in the biological system also are contained in chemical model systems.The development of a QSAR can be divided into subproblems:1.

  5. 10. T cell dependent B lymphocyte activation, growth and maturation : the role of lymphokines

    Författare :Sven Pettersson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TH cell activated B- cell growth maturation B-cell growth factor BSF-pI B-cel1 maturation factor s BMA neonatal B-cell prol iferation anti body secretion;

    Sammanfattning : The present work concerns the regulation of B cell activation, growth and terminal differentiation of helper T cells.T cell dependent (TD) B cell activation requires physical cell to cell contact between competent helper T cells (TH) and B cells and the recognition of MHC Class II antigens.
