  1. 21. Cold-induced nonshivering thermogenesis : tissue origin, activation, recruitment

    Författare :Valeria Golozoubova; Martin Brand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Sammanfattning : Two types of heat production, shivering and nonshivering thermogenesis, are activated in mammals in the cold. In small mammals, nonshivering thermogenesis becomes the main source of heat upon long-term cold exposure. LÄS MER

  3. 22. Photon migration in tissue : laser induced fluorescence for cancer diagnostics and influence of optical properties on microvascular Doppler spectroscopy

    Författare :Henrik Nilsson; Othar Svaasand Svansand; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser induced flourescence (LIF) is an "optical biopsy" method, based on the selective accumulation of fluorophores in neoplastic tissue. Two recently developed, non-photosensitizing tumor seeking carotenoporphyrins were assessed regarding tumor selectivity, and biodistribution, in experimental animals. LÄS MER

  4. 23. Laser doppler tissue flowmetry : fiberoptic methods in microvascular research

    Författare :Göran Salerud; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler flowmetry (LDF) constitutes a method for measuring the flux of blood cells in the microcirculatory bed. Photons are scattered in the moving blood cells, where they undergo a frequency shift according to the Doppler principle. LÄS MER

  5. 24. Diffusion in Bone Tissue

    Författare :Gustav Lindberg; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; diffusion; stress enhanced; finite element method; steady-state; periosteal membrane; diffusion in bovine bone; diffusion experiment; Conductivity measurement; Fick’s law; Fourier series; Kalman filter; transient solution;

    Sammanfattning : In order to prevent or modify the processes of bone degeneration the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. LÄS MER

  7. 25. Tissue Factor in Complex : Studies of interactions between blood coagulation proteins

    Författare :Karin Carlsson; Magdalena Svensson; Susanne Wisén; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Many biological processes rely on specific protein-protein interactions, for example immune responses, cell signaling, transcription, and blood coagulation. Blood coagulation is initiated when a vessel wall is damaged, exposing tissue factor (TF) to the circulating factor VII/factor VIIa (FVII/FVIIa) which results in the formation of the TF:FVIIa complex and thereby the initiation of blood coagulation.
