  1. 1. Imaging Anxiety : Neurochemistry in Anxiety Disorders Assessed by Positron Emission Tomography

    Författare :Andreas Frick; Mats Fredrikson; Tomas Furmark; David J Nutt; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fear; Brain; Serotonin; Neurokinin; Substance P; Psychology; Psykologi;

    Sammanfattning : Anxiety disorders, including social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD) are common and disabling conditions. Largely based on animal and pharmacological studies, both the serotonergic and substance P/neurokinin-1 (SP/NK1) systems have been implicated in their underlying pathology. LÄS MER

  3. 2. Diabetes in 3D : β-cell mass assessments in disease models & evaluation of SPECT based imaging

    Författare :Saba Parween; Ulf Ahlgren; Helena Edlund; Eckhard Lammert; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optical projection tomography; Diabetes; β-cell mass; disease etiology; 3D imaging; radiotracers; Single photon emission computed tomography; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. LÄS MER

  4. 3. PET and MR imaging in prostate cancer

    Författare :Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

    Sammanfattning : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. LÄS MER

  5. 4. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

  7. 5. Guided Regeneration of the Human Skin : in vitro and in vivo studies

    Författare :Erika Nyman; Gunnar Kratz; Fredrik Huss; Joakim Henricson; Lars B. Dahlin; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Every day and in all parts of the world, humans experience different grades of wounding and tissue loss of the skin, thus initiating one of the most complex biological processes. Acute and chronic wounds, as well as the additional problem of skin scarring, involve not only great suffering for the patient but also extensive health care costs for the society. LÄS MER
