1. 16. Methods of image acquisition and calibration for x-ray computed tomography

   Författare :Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

   Sammanfattning : X-ray computed tomography (CT) is a common medical imaging device for acquiring high-resolution 3D images of the interior of the human body. The images are formed by mathematical reconstruction from hundreds of planar x-ray images that have been acquired during less then a second. LÄS MER

3. 17. Molecular dissection of the Goodpasture epitope

   Författare :Thomas Hellmark; Njurmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urologi; autoimmune; anti-GBM nephritis; glomerulonephritis; nephrology; Urology; nefrologi;

   Sammanfattning : Goodpasture disease is a prototype autoimmune disease that is characterized by a rapidly progressive glomerulonephritis, with or without lung haemorrhage, associated with autoantibodies against the glomerular basement membrane. The major antigen has previously been shown to be the non-collagenous domain of the a3 chain of type IV collagen, one of the six known a chains of type IV collagen. LÄS MER

4. 18. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

   Författare :Cecilia Leal; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

   Sammanfattning : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. LÄS MER

5. 19. Synchrotron X-ray Scattering and Monte Carlo Simulations of Structure and Forces in Silicate Nanoplatelet Dispersions

   Författare :Mo Segad; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAXS; MC simulations; Swelling; Tactoids; EXAFS; DLS; Cryo-TEM; Nanoplatelets; MX80; Na Ca montmorillonite.;

   Sammanfattning : Clays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. LÄS MER

7. 20. Unusual vascular responses in the umbilical artery, mediated by endothelin-like receptors

   Författare :Maria Laursen; Urogynekologi och reproduktionsfarmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; sexuality; Obstetrik; gynekologi; andrologi; sexualitet; andrology; gynaecology; Obstetrics; Medicin människa och djur ; Medicine human and vertebrates ; unusual vascular responses; endothelin-like receptors; human umbilical artery; reproduktion;

   Sammanfattning : In this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery.
