  1. 1. Radioiodine Therapy of Hyperthyroidism - Simplified patient-specific absorbed dose planning

    Författare :Helene Jönsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Radiofarmaceutisk teknik; Radiopharmaceutical technology; absorbed dose. optimise; hyperthyroidism; therapy; 131-I; radioiodine; Nukleärmedicin; radiobiology; Nuclear medicine;

    Sammanfattning : Radioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined.

  2. 2. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

    Författare :Helene Larsson Jönsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

    Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER

  3. 3. Droplet microfluidics for high throughput biological analysis

    Författare :Håkan Jönsson; Helene Andersson-Svahn; Andrew Griffiths; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Microfluidics; Droplet microfluidics; High throughput biology; Single cell analysis; Hydrodynamic separation; Enzyme amplification; Fluorescence polarization; Microfabrication; Bioengineering; Bioteknik; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : Many areas of biological research increasingly perform large-scale analyses.  In genomics the entire gene repertoire of an organism is analyzed.  Proteomics attempts to understand the function and expression patterns of all proteins in a cell or organism. LÄS MER

  4. 4. Droplet microfluidics for screening and sorting of microbial cell factories

    Författare :Sara Björk; Helene Svahn Andersson; Håkan Jönsson; Christoph Merten; KTH; []
    Nyckelord :Droplet microfluidics; Cell factories; High-throughput screening; Cell culture; Biotechnology; Bioteknologi;

    Sammanfattning : Cell factories are cells that have been engineered to produce a compound of interest, ranging from biopharmaceuticals to biofuels. With advances in metabolic engineering, the number of cell factory variants to evaluate has increased dramatically, necessitating screening methods with increased throughput. LÄS MER

  5. 5. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Författare :Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER
