  2. 1. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Author : Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Abstract : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). READ MORE

    Abstract : G protein-coupled receptors (GPCRs) are one of the largest protein families in mammals. GPCRs are instrumental for hormonal and neurotransmitter signalling and are important in all major physiological systems of the body. READ MORE

  5. 3. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties

    Author : Maryam Tofiq; Göran Alderborn; Ann-Sofie Persson; Josefina Nordström; Peter Kleinebudde; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dry granulation; Powder compression; Compression parameters; Granule composition; Granule structure; Granule strength; Granule fragmentation; Granule deformation; Tablet tensile strength; Loss of tabletability;

    Abstract : Dry granulation (DG) is often utilized as an intermediate process during tablet manufacturing, for improving flow characteristics of the powder blend and/or reducing segregation issues related to the active pharmaceutical ingredient (API). The resulting granules exhibit typically irregular shapes with rough surfaces and their mechanical properties are related to the feeding powder and the process parameters used during the DG.
