  1. 6. Application of new technology : MEPS and LC-MS/MS for determination of therapeutic drugs

    Författare :Rana Said; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bioanalysis most often requires an extraction procedure to isolate the target compounds from a complex matrix. The aim of this work was to evaluate microextraction in packed syringe (MEPS) performance as a sample preparation technique by developing new analytical methods for different categories of compounds utilizing MEPS in combination with LC-MS/MS.

  3. 7. A three dimensional scaffold for single staged tissue engineering

    Författare :Said Zeiai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Study I. Aims: Evaluate a collagen-PCL scaffold with minced bladder mucosa in vitro. M&M: Minced tissue was cultured on top of the scaffold. Scaffold properties were evaluated. LÄS MER

  4. 8. Photosystem II : organization, function and regulation

    Författare :Said Eshaghi; Matthias Rögner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : What makes plants, green algae and cyanobacteria so remarkable is their ability to convert light energy to chemical energy and at the same time evolve oxygen. In order to do so, they have developed a complex molecular machinery involving pigment and co-factor binding multi-protein complexes. LÄS MER

  5. 9. Effect of thimerosal on the murine immune system : especially induction of systemic autoimmunity

    Författare :Said Havarinasab; Per Hultman; Klas Nordlind; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; thimerosal; ethylmercury; autoimmunity; mice; immunosuppression; Th1; Th2; Pathology; Patologi;

    Sammanfattning : The organic mercury compound ethylmercurithiosalicylate (thimerosal), an antiseptic and a preservative, has recently raised public health concern due to its presence in vaccines globally. Thimerosal dissociates in the body to thiosalicylate and ethyl mercury (EtHg), which is partly converted to inorganic mercuric mercury (Hg2+). LÄS MER

  7. 10. On Dynamic Spectrum Access in Cognitive Radio Networking

    Författare :Said Rutabayiro Ngoga; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Cognitive Radio Networking; Dynamic Spectrum Access; Wireless Communications;

    Sammanfattning : The exploding increase of wireless communications combined with the existing inefficient usage of the licensed spectrum gives a strong impetus to the development and standardization of cognitive radio networking and communications. In this dissertation, a framework for Dynamic Spectrum Access (DSA) is first presented, which is the enabling technology for increasing the spectral efficiency of wireless communications. LÄS MER
