    Abstract : The general iron fortification of white wheat flour was removed after 50 years of iron fortification. It was considered important to evaluate the effects of withdrawal of iron fortification among vulnerable groups in the population. Adolescents have high iron requirements for growth and the girls for menstrual losses. READ MORE

  5. 13. Physical activity, cardiovascular fitness and abdominal adiposity in children and adolescents

    Author : Francisco B Ortega Porcel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Physical activity; accelerometry; fitness; aerobic capacity; adiposity; waist circumference; children; adolescents;

    Abstract : Cardiovascular fitness (CVF) and adiposity, especially abdominal adiposity, are well-known factors associated with general health status in childhood and adolescents. Physical activity (PA) may play a crucial role in CVF enhancement and the prevention of abdominal adiposity accumulation. READ MORE

  6. 14. Teaching genetics - a linguistic challenge : A classroom study of secondary teachers' talk about genes, traits and proteins

An understanding of how language is used in action can give detailed information about how the subject matter is presented to the students as well as insights in linguistic challenges. READ MORE

  7. 15. Binding and immunogenicity of MHC class-I specific peptides and glycopeptides

    Author : Ussama M Abdel-Motal; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Short synthetic MHC class I (MHC-I) Db and Kb binding peptides were found to be strongly immunogenic and capable of inducing virus-specific cytotoxic T lymphocyte (CTL) responses. Restimulation of primed splenocytes with a low peptide concentration generated optimal CTL responses. READ MORE
