  1. 21. Quantification and optimisation of lung ventilation SPECT images

    Författare :Pernilla Norberg; Michael Sandborg; Gudrun Alm Carlsson; Agneta Gustafsson; Katarina Sjögreen Gleisner; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Currently, lung function tests are the gold standard for lung function measurements. Since the outcome of a lung function test is a summation of the status of the whole lung, significant changes in lung function may occur before a deviation from the norm can be identified. LÄS MER

  3. 22. Alternative Methods for Assessment of Split Renal Function

    Författare :Henrik Björkman; Anders Magnusson; Jonas Wadström; Torbjörn Andersson; Uppsala universitet; []
    Nyckelord :Radiology; Split renal function; Live kidney donor; CT; Renography; Dynamic MRI; Renal volume; Respiratory triggering; Radiologisk forskning;

    Sammanfattning : Living kidney donation is a clinical situation with unique features in the sense that healthy individuals voluntarily expose themselves to certain risks and inconveniences. Therefore, eliminating as much of the associated discomfort as possible is crucial. LÄS MER

  4. 23. Novel computational methods for image analysis and quantification using position sensitive radiation detectors

    Författare :Alejandro Sanchez Crespo; Stig A. Larsson; Magnus Dahlbom; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SPET; PET; CMOS; spatial resolution; photon depth of interaction; positron annihilation; positron range; non-collinearity; scatter; attenuation; lung ventilation; lung perfusion; breast tumour; Medicine; Medicin;

    Sammanfattning : The major advantage of position sensitive radiation detector systems lies in their ability to non invasively map the regional distribution of the emitted radiation in real-time. Three of such detector systems were studied in this thesis, gamma-cameras, positron cameras and CMOS image sensors. LÄS MER

  5. 24. Rational and combinatorial protein engineering for vaccine delivery and drug targeting

    Författare :Maria Wikman; Stefan Ståhl; Carl A. K. Borrebaeck; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; affibody; affinity chromatography; biotin; combinatorial; delivery; phage display; Biomedicin; Microbiology; Mikrobiologi;

    Sammanfattning : This thesis describes recombinant proteins that have been generated by rational and combinatorial protein engineering strategies for use in subunit vaccine delivery and tumor targeting.In a first series of studies, recombinant methods for incorporating immunogens into an adjuvant formulation, e.g. LÄS MER

  7. 25. Regulation and function of the human fallopian tube

    Författare :Kjell Wånggren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fallopian tube; endometrium; embryo; transport; prostaglandin; receptors; progesterone; mifepristone; LIF; LIFR; gp130;

    Sammanfattning : The Fallopian tube is essential for human reproduction. Transport of the spermatozoa, the egg, and later the pre-embryo is believed to be aided by muscular contractions in the wall of the Fallopian tube and cilia in the mucosa. LÄS MER
