  1. 16. Sensitivity and selectivity studies in capillary electrophoresis

    Författare :Maria Petersson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptides; dansyl amino acids; imaging detection; cyclodextrins; enantiomer separation; acoustic levitation; solid-phase extraction; preconcentration; capillary electrophoresis; micellar electrokinetic chromatography; drugs; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

  3. 17. Molecular epidemiology of tuberculosis

    Författare :Ramona Petersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tuberculosis (TB) is a global epidemic, with one third of the world's population infected, at least 9 million new active cases per year and about 2 million deaths per year. Without adequate chemotherapy treatment TB may be a mortal disease. LÄS MER

  4. 18. Effect of body posture on regional ventilation and perfusion at normal and increased gravity

    Författare :Johan Petersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The prone position is increasingly used to improve arterial oxygenation in intensive care patients with severe acute respiratory failure. This beneficial response is well documented but our understanding of the responsible mechanisms remains incomplete, as does our knowledge of the effect of posture on lung function in healthy individuals.

  5. 19. Cereal Dietary Fibre - Physicochemical Properties and Suitability for Addition to Low-Fat Meat Products

    Författare :Karin Petersson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dietary fibre; cereals; oat bran; rye bran; wheat bran; barley fibre; hydrolytic enzymes; physicochemical properties; low-fat sausages; low-fat meatballs; sensory perception; texture;

    Sammanfattning : It is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. LÄS MER

  7. 20. Pharmacovigilance : spontaneous reporting in health care

    Författare :Elisabet Ekman; Göran Petersson; Susanna Wallerstedt; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacovigilance; adverse drug reaction; spontaneous reporting; nurses; physicians; attitudes; torsades de pointes; erectile dysfunction; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Pharmacovigilance in healthcare is essential for safe drug treatment. Spontaneous reporting is the most common source of information in the context of implementing label changes and taking a drug off the market. However, underreporting is found to be very prevalent. LÄS MER
