1. 11. Methods for Processing and Analysis of Biomedical TEM Images

   Författare :Amit Suveer; Ida-Maria Sintorn; Carolina Wählby; Natasa Sladoje; Jari Hyttinen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; deep learning; transmission electron microscopy; denoising; super-resolution reconstruction; registration; detection; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Transmission Electron Microscopy (TEM) has the high resolving capability and high clinical significance; however, the current manual diagnostic procedure using TEM is complicated and time-consuming, requiring rarely available expertise for analyzing TEM images of the biological specimen. This thesis addresses the bottlenecks of TEM-based analysis by proposing image analysis methods to automate and improve critical time-consuming steps of currently manual diagnostic procedures.

5. 14. Epidemiological aspects of drug-related vitamin D deficiency and osteoporotic fractures

   Författare :Ola Nordqvist; Martin Carlsson; Pär Wanby; Thomas Neumark; Björn Wettermark; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vitamin D; secondary osteoporosis; fractures; drug risk management; medical guideline adherence; electronic health records; real-world data; risk assessment; awareness; attitudes; personalised medicine; cross-sectional study; cohort study; qualitative analysis; thematic analysis; pharmacoepidemiology; Biomedical Sciences; Biomedicinsk vetenskap;

   Sammanfattning : Background: Vitamin D deficiency, secondary osteoporosis and low-energy fractures (LEF) as side effects of specific drugs were first described more than half a century ago. These effects are recognized in guidelines where patients prescribed risk drugs are recommended follow-up with testing and supplementation. LÄS MER

7. 15. Pharmaceutical and Biomedical Applications of Spectroscopy in the Photon Migration Regime

   Författare :Tomas Svensson; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosimetry; Biomedical optics; Pharmaceutical analysis; Monte Carlo; Scattering media; Photon migration; Laser spectroscopy; High-resolution spectroscopy; Time-resolved spectroscopy; Time-of-flight;

   Sammanfattning : The present thesis is devoted to two different matters: One part is the development of a novel optical technique for characterisation of solid pharmaceutical materials. The other part being the continued development of photon time-of-flight spectroscopy, as well as exploration of new application areas of this method. LÄS MER
