  2. 1. Characterization of Endocrine Cells and Tumours in the Stomach

    Author : Apostolos V. Tsolakis; Eva T. Janson; Mats Stridsberg; Guida M. Portela-Gomes; Ola Nilsson; Uppsala universitet; []
    Keywords : Oncology; ECL cells; ghrelin cells; gastric endocrine tumours; VMAT-2; ghrelin; obestatin; HDC; U-MeImAA; Onkologi;

    Abstract : Enterochromaffin-like (ECL) and ghrelin cells, in the human gastric mucosa and in gastric endocrine tumours (GETs), were subclassified with respect to immunohistochemical reaction vs. vesicular monoamine transporter 2 (VMAT-2), ghrelin/obestatin, and histidine decarboxylase (HDC).

  4. 2. Electrostatic turbulence and electron heating in collisionless shocks

    Author : Ahmad Lalti; Yuri V. Khotyaintsev; Hans Nilsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Collisionless shocks are one of the most peculiar phenomena in space where non-linear collective phenomena in the plasma dominate the dynamics. They are believed to be one of the most efficient particle accelerators in the universe, and have internal dynamics that are yet to be fully explored. READ MORE

  5. 3. Liver tissue characterization and influence of chemotherapy in liver surgery

    Author : Jan Nilsson; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal liver metastases; liver regeneration; incisional hernia; steatosis; hepatic microcirculation; diffuse reflectance spectroscopy; DRS; sidestream dark-field imaging; SDF; laser speckle contrast imaging; LSCI;

    Abstract : Background & Aims: Primary liver cancer is the second most common cause of death from cancer worldwide. In the western world, the majority of liver malignancies consist of colorectal metastases. Liver resection is the primary treatment for cure in liver tumor disease. READ MORE

  6. 4. Impact of Surgery for Primary Hyperparathyroidism

    Author : Martin Nilsson; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primär hyperparatyroidism; paratyroidektomi; mortalitet; frakturer; bone mineral density; hjärt-kärlsjukdom; kalcium; paratyroideahormon; adenom; multiglandulär sjukdom; primary hyperparathyroidism; parathyroidectomy; mortality; fractures; bone mineral density; cardiovascular disease; calcium; parathyroid hormone; adenoma; multiglandular disease;

    Abstract : Primär hyperparathyroidism, pHPT, är en relativt vanlig endokrinologisk sjukdom som karaktäriseras av förhöjd utsöndring av bisköldkörtelhormon, PTH, i förhållande till kalciumnivån i blodet. Sjukdomen är vanligast hos äldre och kvinnor, och orsakas oftast av en godartad tumör i en bisköldkörtel (80–85% av fallen) eller mer diffus förstoring av flera bisköldkörtlar. READ MORE

  7. 5. Volumetric MRI measurements of velocity and flow - Accuracy, visualisation and technical improvements

    Author : Anders Nilsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; 4D flow; phase contrast MRI; velocity mapping;

    Abstract : In the last two decades, phase-contrast magnetic resonance imaging (PC-MRI) has evolved from two-dimensional velocity and flow measurements to volumetric, time-resolved depictions of velocity fields (4D PC). The acquisition of time-resolved velocity fields allows flow visualisations that might provide better understanding of the dynamics of the cardiac system. READ MORE
