  1. 16. Unpacking Rational Use of Antibiotics : Policy in Medical Practice and the Medical Debate

    Författare :Hedvig Gröndal; Tora Holmberg; Ericka Johnson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Antibiotics; Policy; Medical Sociology; Actor-Network Theory; Human-microbial relations; Antimicrobial Resistance; Everyday Infections; Material semiotics; Medical sociology; Medical objects; Medical technologies; Medical knowledge; Sociologi; Sociology;

    Sammanfattning : Rational use of antibiotics–using antibiotics only when needed and in the right way–is a prioritized goal in policy aimed at preventing antimicrobial resistance. A vast body of research is devoted to understanding why unnecessary antibiotics are prescribed. LÄS MER

  3. 17. DNA precursor biosynthesis-allosteric regulation and medical applications

    Författare :Reza Rofougaran; Anders Hofer; Thomas Borén; Staffan Eriksson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; DNA biosynthesis; ribonucleotide reductase; allosteric regulation; Trypanosoma brucei; adenosine kinase; nucleoside analogs; mitochondrial DNA; TWINKLE; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Ribonucleotide reductase (RNR) is a key enzyme for de novo dNTP biosynthesis. We have studied nucleotide-dependent oligomerization of the allosterically regulated mammalian RNR using a mass spectrometry–related technique called Gas-phase Electrophoretic Mobility Macromolecule Analysis (GEMMA).

  5. 19. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography

    Författare :Cheng Xu; Hans Bornefalk; Mats Danielsson; Ami Altman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photon counting; spectral computed tomography; silicon strip detector; ASIC; energy resolution; cadmium telluride; charge sharing; Monte Carlo simulation; synchrotron;

    Sammanfattning : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.

  7. 20. Efficient Medical Volume Visualization : An Approach Based on Domain Knowledge

    Författare :Claes Lundström; Anders Ynnerman; Hans Knutsson; Dirk Bartz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scientific Visualization; Medical Imaging; Computer Graphics; Volume Rendering; Transfer Function; Level-of-detail; Fuzzy Classification; Uncertainty Visualization; Virtual Autopsies; Medical engineering; Medicinsk teknik;

    Sammanfattning : Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations.
